Development and effect of an N-3 fatty acid-rich spread on the nutritional and cognitive status of school childrenDalton, Annalien 03 1900 (has links)
Thesis (PhD (Food Science))--University of Stellenbosch, 2006. / Long-chain polyunsaturated fatty acids (LCPUFA), especially the n-3 LCPUFA metabolic
products eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) play an important
role as regulators in many biological processes. To date hake (Merluccius capensis) heads, a
rich source of EPA and DHA, have been discarded at sea. The South African Fisheries Policy
Development Committee concerned with the environmental impact of this practice has
rendered it undesirable. The high prevalence of under-nutrition amongst children in South
Africa can be addressed by the supplementation of their diet with this unexploited fish source.
The aim of the current study was to develop a microbiologically safe and sensory acceptable
sandwich spread using fish flour prepared from fish heads, as a prime ingredient. The
intervention trial aimed to compare the effects of an increased dietary intake of n-3 LCPUFA,
specifically DHA, on the blood fatty acid levels and absenteeism (as indicator of immune
function), as well as the cognitive status, of the subjects. The microbiological content of the
sandwich spread was determined after storage for 20 d at 5°C and 15 d at 25°C. Sensory
evaluation was performed by consumers (n = 95; M:F = 44:51; 6 – 9 yr) to determine
acceptance of the five different flavours individually incorporated into the sandwich spread to
mask the fishy note and to provide different flavour options. For the intervention trial
subjects (n = 351) were stratified within class group (A - E) and gender and randomly
assigned to two treatment categories, an experimental group (EG; n = 174) receiving 25 g
sandwich spread.d-1 (191.66 mg DHA. d-1) and a control group (CG; n = 177) receiving an
analogous placebo. On school days (104 d), each subject received two sandwiches consisting
of two slices of bread (ca. 60 g), spread with 25 g of either the placebo or the experimental
spread. Blood samples were drawn at baseline and post intervention. Plasma fatty acid and
red blood cell (RBC) membrane status, C-reactive protein levels, as well as vitamin and
micronutrient status, were determined. Trained test administrators conducted a battery of
cognitive tests. According to South African Government health standards, the sandwich
spread remained microbiologically safe after storage. Male and female consumer respondents
revealed a significant difference between gender preferences of the five different spread
flavours (p <0.05). Significant treatment effects (p <0.05) were observed in n-3 LCPUFA
status of the EG, as well as for their absenteeism from school. The two subtests of the
Hopkins Verbal Learning test, Recognition and Discrimination Index, showed significant
differences between the EG and CG (p <0.05) post intervention in the Grade 2 subjects. The
Spelling tests also showed a significant difference between the two groups (p <0.05). In the
current study a microbiologically safe and sensory acceptable sandwich spread was developed
and tested during an intervention trial, and could possibly in future, provide a healthier option in the School Nutritional Programme. This study proved that supplementation of children (6 -
9 yr) with n-3 LCPUFA, with specific reference to EPA and DHA from a marine source,
could have a beneficial effect on their fatty acid status and absenteeism from school. Based
on the outcomes of the Hopkins Verbal Learning test and Spelling test, the current study
proved that an n-3 fatty acid-rich spread improved the learning ability and memory of
children.

The prevalence of obesity amongst learners attending the schools in Belhar, Delft and Mfuleni in Cape Town, South AfricaSomers, Avril January 2004 (has links)
Thesis (MTech (Biomedical Technology))--Peninsula Technikon, 2004. / The prevalence of obesity amongst both the adult and paediatric population has
assumed almost epidemic proportions in many developed and developing
countries. A recent study by the Medical Research Council found that a disturbing
20% of all South African children could be categorized as being obese. Limited
data is currently available on the prevalence of obesity in South African children,
particularly from the previously disadvantaged population. Given the global
epidemic of paediatric obesity, hypertension and type-2-diabetes and the limited
available data relating to obese South African children, further studies to enhance
the understanding of the risk factors associated with the epidemic are imperative.

Comparison of packed school lunches of boys and girls in primary schools in East LondonWilkinson, Jeanne January 2015 (has links)
Submitted in fulfilment of the requirements for the degree Master of Applied Science in Food and Nutrition, Durban University of Technology, 2015. / Objective: To determine the contribution of packed school lunches to the daily food intake of girls and boys in two Primary Schools in East London.
Methods: The study was conducted among 199 girls and boys aged 9-13 years. Three 24-Hour recalls and a Food Frequency Questionnaire were completed during an interview with the participants to gather data on dietary patterns over a period of three consecutive days. Additionally, the contents of one lunch box per participant were recorded and weighed. Anthropometrics and socio-demographics were also completed during the interview.
Results: The three 24-Hour Recall nutrient measurements revealed a low energy intake in 91 percent for the girls and 77 percent for the boys who were consuming below the recommended Estimated Energy Requirement for energy. The lunchboxes contributed one-third of the daily nutrient intake of the children. The 24-Hour recall revealed an energy-dense, carbohydrate-based diet. The contribution of total fat (30-32%) to the total energy is higher than the World Health Organization (WHO) recommendation of 15-30 percent. The daily fruit and vegetable intake (215.1g and 216.9g), according to the 24-Hour recall and lunchbox analysis respectively, was insufficient compared to the WHO-recommendation of >400g /day. Although the mean intake of most of the nutrients was sufficient, a large number of the participants did not meet requirements for the age group. The risk of overweight was high (24% for girls and 29.2% for boys) with 1.5 percent falling into the obese category.
Conclusion: The results of the study indicated a high-fat and carbohydrate intake and a very low fruit and vegetable intake. The girl participants had better food choices for the lunchboxes but the majority of the participant’s daily intake did not meet the basic requirements of a balanced diet. The risk of overweight in the age category is an increasing problem among low- and high-income countries. Nutritional education should concentrate on healthy food choices in school lunchboxes as a large part of the day is spent at school.

Impact of a nutrition education programme on the nutrition knowledge of grade R learners in DurbanVermeer, Susan Inge January 2015 (has links)
Submitted in fulfillment of the requirements of the Masters of Applied Science in Food and Nutrition, Durban University of Technology, 2015. / AIM: The aim of the study was to identify the need, develop, implement and determine the effect of a Grade R Nutrition Education Programme (NEP) in order to make recommendations to the South African Department of Basic Education (DBE) to include an effective NEP in the pre-primary school education curriculum.
OBJECTIVES: The objectives for this study is in two phases, The objective of the baseline study was to assess the need for nutrition education (NE) in Grade R in suburban areas of Durban and identify the most suitable nutrition education tools (NETs) for this age group.
For the intervention study the objectives were 1) to develop a nutrition knowledge questionnaire (NKQ) to determine the existing nutrition knowledge of Grade R learners in suburban government and private schools in Durban, 2) to develop a nutrition education programme (NEP) for Grade R based on the South African Food-Based Dietary Guidelines (FBDGs) and the food groups, 3) to implement the NEP in Grade R in a government and private school, 4) to determine the effect of the NEP on the retention of FBDGs (Section one) and food group (Section two) knowledge, and 5) to compare the results between the control group (CG) and the government (EGG) and private (EPG) experimental school groups, and between genders.
METHODS: A self-administered nutrition education needs questionnaire was completed by 20 Grade R teachers in Durban suburban schools.
Nutrition education material was identified based on the results from the pilot study and a Nutrition education programme developed. The classroom-based intervention study involved 120 Grade R learners in three schools, two experimental schools: government (n=37) and private (n=40), with a control school (n=43), with 35 percent (n= 42) male and 65 percent (n=78) female participants, ranging in age from five to seven years. A validated questionnaire assessed baseline nutrition knowledge of these children. A qualified foundation phase teacher was trained to implement the NEP. The experimental school groups received eight one hour nutrition education (NE) lessons over an eight week period; the control group did not receive any NE. During the lesson firstly theory was covered then the children worked on the related fun activities in the Healthy Eating Activity Book (HEAB) and lastly involved in the nutrition educational games. These included a food group plate puzzles, a NEP board game, a card game and ‘My little story books’. A post-test determined the impact of the intervention.
RESULTS: The baseline study confirmed the need for NE in Grade R and identified suitable NETs that were used in the intervention.
At pre-test, the nutrition knowledge of Grade R children in the two experimental groups (EG) and one CG was very similar with knowledge of FBDGs greater than knowledge relating to the food groups.
Both Grade R EGs showed a significant increase in knowledge for the whole test immediately after the intervention with the CG, achieving similar post-to pre-test results. The intervention had a significant impact on nutrition knowledge of Grade R children in both experimental schools (EGG p=0.004 and EPG p=0.001). The EPG were most knowledgeable regarding FBDGs with no significant difference in knowledge of the EGG. Food group knowledge in all schools was poor at baseline and the NEP resulted in the EGG obtaining the highest post-test results. Post-intervention for the whole test the EGG were marginally (0.80 percent) more knowledgeable than the EPG.
The knowledge of boys and girls were very similar in pre-and post-test results. However, the boys were fractionally more knowledgeable than the girls in relation to the whole post-test. In Section two, relating to food group knowledge, girls were slightly more knowledgeable than boys although both genders lacked knowledge in relation to which foods belonged to a particular food group.
CONCLUSION: The primary aim of formal NE was met as the statistical significance between the CG and experimental group post-test results was evident in the majority of Section one questions and in all questions in Section two. The NEP resulted in similar increase in knowledge of Grade R learners in the government and private experimental school groups in Durban. In addition, the boys and girls showed a minimal difference in nutrition knowledge.

The impact of home gardens on dietary diversity, nutrient intake and nutritional status of pre-school children in a home garden project in Eatonside, the Vaal triangle, Johannesburg, South Africa.Selepe, Bolyn Mosa. January 2010 (has links)
Urban agriculture is a strategy poor urban, informal settlement residents adopt to reduce
poverty and improve food security and child nutrition. It is widely asserted in the literature
and development circles that household vegetable gardens can provide a significant
percentage of recommended dietary allowances of macro- and micro-nutrients in the diets of
pre-school children. These children are vulnerable in terms of food access and nutrition. The
first five years of a child’s life are crucial to psychological well-being. This study set out to
determine the impact of home gardens on access to food, dietary diversity and nutrient intake
of pre-school children in an informal settlement in Eatonside, in the Vaal Region,
Johannesburg, South Africa.
The home gardening project was undertaken in five phases, namely the planning phase; a
baseline survey (including quantitative food intake frequencies, 24-hour recall, individual
dietary diversity questionnaires and anthropometric measurements); a training programme on
home gardens; planting and tending the gardens and evaluating the impact of home gardens
on access to food, dietary diversity and nutrient intake of pre-school children.
Children aged two to five years (n=40) were selected to participate in the study. The sample
population consisted of 22 boys and 18 girls. The children were categorised into three groups
at the start of the project: children of 24-35 months (four boys and one girl), 36-47 months
(four boys and five girls) and 48-60 months (14 boys and 12 girls). All but 10 per cent of the
children’s consumption of foods in the food groups increased. At the start of the project, low
consumption rates were observed for white tubers and roots, vitamin A-rich fruit, other fruit
and fish. After the gardening project, the number of children consuming vegetables increased
considerably. There was an increase in the intake of food groups over the period of the
project. The number of children consuming vitamin A-rich increased the most, with all
children (45 per cent improvement) consuming vitamin A-rich vegetables at the end of the
project, compared with just over half at the start of the project. The consumption of
vegetables increased with 78 per cent of the children consuming beans and 33 per cent
beetroot. Most children (95 per cent) consumed cabbage, carrots and spinach post-home
gardening. Seventy eight percent of children consumed beans by the end of the project, but
only a third of the children had consumed beetroot during the post-project survey period.
Intakes of all nutrients considered in the study improved by the end of the project, except for
energy and calcium, which dropped marginally, but both remained at around 50 per cent
below requirements.
Twenty five percent of boys (24-35 months) were underweight and below the 50th percentile
at the pre- and post-project stages. The same boys were severely stunted (on average -4.41
standard deviations below the third percentile). Of the boys aged 36-47 months, 25 per cent
were stunted pre-project, but by the end of the project, this number had decreased to 50 per
cent. Twenty one per cent of the older boys (48-60 months) were within their normal height
for age.
Twenty five per cent of girls were underweight (36-47 months). A slight change was
observed in the 36-47 month group, where the mean changed from -0.14 standard deviations
(below 50th percentile) pre-project to -0.5 (below 50th percentile) post-project. All girls aged
24-35 months were below -2 standard deviations pre-project. After the home gardening
project, the figure dropped to 50 per cent. For girls aged 36-47 months, 25 per cent were
below -3 standard deviations after the project, compared with 20 per cent pre-project. Height-for-
age for girls aged 36-47 months dropped by 10 per cent below -2 standard deviation post-home
gardening. Girls from 24 to 35 months were severely stunted [-3.02 (below 3rd
percentile) pre- and -2.31 (below 5th percentile) post-project]. Stunting was observed in 36-47
months girls who had means of -2.39 (below 3rd percentile) and 1.86 (below 25th percentile)
both pre-and post-gardening respectively and were at risk of malnutrition. The older girls
were well nourished with means of height-for-age at -0.88 (below 50th percentile) pre-project
and -0.92 (below 50th percentile) post-project.
Home-gardening improved food access, dietary diversity, energy, protein, carbohydrate, fat,
fibre, vitamin A and iron intakes, but did not make a significant impact on the malnutrition
of the children in the project or ensure adequate intakes. Home gardens had a positive
impact on height-for-age scores; but had no significant impact on mean weight-for-age and
height-for-weight z-scores of the pre-school children. Increases in carbohydrate and fat
intakes were shown to have the only significant impact on the children’s nutritional status
and only with regard to improving height-for-age scores. The results show that the gardens
did not have the expected impact on children’s nutrition, but confirm that increases in
incomes from gardening are likely to have a greater impact through savings from consuming
produce grown and selling produce to buy energy-dense foods for the children. This needs
to be considered in nutrition interventions. / Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2010.

The tuck shop purchasing practices of grade 4 learners at selected primary schools in Pietermar[it]zburg, South Africa.Wiles, Nicola Laurelle. 12 November 2013 (has links)
Aim: To determine whether the tuck shop purchasing habits of Grade 4 learners were
contributing towards the development of childhood overweight and obesity.
Objectives: To assess the nutritional quality of the food and beverages available for learners to
purchase; items regularly purchased from the tuck shop as well as factors influencing the
learner’s decision to purchase these items; the anthropometric and socio-demographic
characteristics of grade 4 learners as well as their nutrition knowledge related to the tuck shop items purchased.
Method: A survey administered to 11 tuck shop managers, a questionnaire administered to 311
Grade 4 learners and two single-sex focus groups of 5 learners each were conducted.
Results: Fifty six percent of the sample were female (n=173) and 44% were male (n=138).
Twenty seven percent of the study sample was overweight (n = 83) and 27% were obese (n = 85).
Eighty six percent of learners (n = 266) claimed to buy from their school tuck shop. Twenty two
percent of learners purchased from their tuck shop at least three times per week (n =58). Learners
who purchased from the tuck shop had a significantly higher BMI than those who did not (p = 0.020). Learners who purchased from the tuck shop spent on average R8,38 per day with a
minimum of R1 and a maximum of R40 (standard deviation R5.39). The most popular reasons
for visiting the tuck shop included “this is my favourite thing to eat or drink” (66.5%, n = 177)
and “I only have enough money to buy this item” (47.0%, n = 125).
Savoury pies were the most popular "lunch" item for all learners for both food breaks (45%, n = 5 schools and 27.3%, n = 3 schools) selling the most number of units (43) per day at eight of the
eleven schools (72.7%). Iced popsicles were sold at almost every school, ranked as the cheapest
beverage and also sold the most number of units (40.7). Healthy beverages sold included canned
fruit juice and water, while healthy snacks consisted of dried fruit, fruit salad, bananas, yoghurt
and health muffins. The average healthy snack contained almost half the kilojoules of its
unhealthy counterpart (465kJ vs 806kJ). Nutritional analyses of the healthy lunch options
revealed total fat contents that exceeded the DRI and South African recommended limit.
Perceived barriers to stocking healthy items included cost and refrigeration restrictions. The average score for the food groups was only 33% indicating that learners were not familiar
with the Food Based Dietary Guidelines (FBDG). Further analyses showed that the total
knowledge scores of those learners that reported to buy from the tuck shop frequently, was
significantly lower when compared to the total knowledge scores of those learners who bought
from the tuck shop less frequently (13.0 ± 3.9 and 11.6 ± 3.1, respectively; p < 0.05). Logistic
regression analysis confirmed that the total knowledge of a learner could be used to predict
whether he or she is more likely to make purchases from the tuck shop (significance = 0.017).
Focus group results revealed that learners are aware of “healthy” and “unhealthy” tuck shop
items. Most learners stated that they would continue to purchase items from their tuck shop if all “unhealthy” items were removed.
Conclusion: Primary school tuck shops of well resourced schools in Pietermaritzburg are
contributing to childhood overweight and obesity through a combination of factors. These
include the poor nutritional quality of the items stocked at the tuck shop as well as the poor tuck
shop purchasing practices. Much consultation is required amongst dieticians, school principals
and privatised tuck shop managers to overcome barriers to stocking healthy items. School
management and government have an important role to play in imposing restrictions on the sale
of unhealthy items; along with improving the quality of the nutrition education curriculum to
ensure that learners are able to translate their knowledge into healthier purchasing practices. / Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2011.

Nutrient intakes, dietary diversity, hunger perceptions and anthropometry of children aged 1-3 years in households producing crops and livestock in South Africa : a secondary analysis of national food consumption survey of 1999.Bolaane, Lenkwetse. January 2006 (has links)
Children less than five years of age are at a risk of growth failure worldwide. The
South African National Food Consumption Survey (NFCS) of 1999 showed that
25.5% of children aged 1 - 3 years were stunted. Poor growth of young children in
developing countries (South Africa included) has been associated with multiple
micronutrient deficiencies because of the use of starchy plant-based complementary
foods with little variety, especially among resource poor households. Dietary
diversification through the use of crop and livestock production has been
recommended as a strategy to improve the micronutrient intake and food security of
households in resource poor settings.
This study was a cross sectional secondary analysis of the South African NFCS of
1999 data, designed to investigate the impact of crop and livestock production on
nutrient intake, dietary diversity, intake of selected food groups, hunger perceptions
and anthropometric status of children aged 1 - 3 years in South Africa. Children
from households producing crops only (n=211), crops and livestock (n=110),
livestock only (n=93) and non-producers were compared at the national, in rural
areas and among households with a total income of less than R12 000.00 per
household per year.
In rural areas and among households with a total income of less than R12 000.00 per
household per year, children in the crops and livestock group had higher nutrient
intakes for energy, vitamin 86, calcium and folate than the other groups (p<0.05),
while the crops only group had higher nutrient intakes for vitamin A and vitamin C.
The majority of children in all the four study groups had less than 67% of the RDAs
for vitamin A, vitamin C, folate, calcium, iron and zinc. In addition , children in all the
groups had a median dietary diversity score of four out of 13 food groups. In rural
areas and among low income households, higher percentages (over 60%) of children
in the crops only group consumed vegetables while the non-producers group was the
lowest (47.7%). The non-producers group had the highest percentages of children
consuming meat and meat products and the crops and livestock and livestock only
groups had the lowest percentages. In both rural areas and among households withlow income, the majority of the households in all the study groups were experiencing
hunger. In rural areas, one in five households were food secure.
Crop and livestock production improved the nutrient intake and the intake of
vegetables of children in rural and poor households. However, nutrient intakes were
not adequate to meet the recommended nutrient levels. The high levels of food
insecurity require support of these households to increase crop and livestock
production and, integration of nutrition education to increase the consumption of the
produced products. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2006.

Comparison of indicators of household food insecurity using data from the 1999 national food consumption survey.Sayed, Nazeeia. January 2006 (has links)
Information on the present situation of household food insecurity in South Africa is
fragmented. There is no comprehensive study comparing different indicators of
household food security. Better information on the household food security situation in
South Africa would permit relevant policy formulation and better decision-making on
the allocation of limited resources. The availability of a national dataset, the first South
African National Food Consumption Survey data (1999) , provided the opportunity to
investigate some of the issues raised above, and to contribute to knowledge on the
measurement of household food security.
The aim of this study was to use the data from the 1999 National Food Consumption
Survey (NFCS) to :
• Determine and compare the prevalence of household food insecurity using different
indicators of household food security ;
• Determine the overlap of households identified as food insecure by the different
indicators (i.e. how many of the same households are identified as food insecure);
and to
• Investigate whether there was any correlation between the indicators selected .
The indicators of household food security selected were: household income, household
hunger experienced, and using the index child: energy and vitamin A intake (from 24
Hour Recall (24HR) and Quantified Food Frequency data), dietary diversity (from
24HR data) and anthropometric indicators stunting and underweight. The cut offs to
determine food insecure household were those used in the NFCS and the cut off for
dietary diversity was exploratory.
The main results of the study were as follows :
• The prevalence estimates of household food insecurity ranged from 10%
(underweight indicator) to 70% (low income indicator). Rural areas consistently
had a higher prevalence of household food insecurity than urban areas . The Free
State and Northern Cape provinces had higher levels of household food insecurity,
with the Western Cape and Gauteng the lower levels of household food insecurity .
• Quantified Food Frequency (QFF) data yielded lower prevalence of household food
insecurity estimates than 24 hour recall (24HR) data. Household food insecurity as
determined by low vitamin A intakes was higher than that determined by low energy
intakes for both the 24HR and QFF data .
• There was little overlap with the indicators (9-52%), indicating that the same
households were not being identified by the different indicators. Low dietary
diversity, low income, 24HR low vitamin A intake and hunger had higher overlaps
with the other indicators. Only 12 of 2826 households (0.4%) were classified by all
nine indicators as food insecure.
• The dataset revealed a number of statistically significant correlations. Overall , low
dietary diversity, low income, 24HR low energy intake and hunger had the stronger
correlations with the other indicators.
Food security is a complex, multi-dimensional concept, and from the findings of this
study there was clearly no single best indicator of household food insecurity status.
Overall , the five better performing indicators (higher overlaps and correlations) were :
low income, 24 hour recall low energy intake, 24 hour recall low vitamin A intake, low
dietary diversity and hunger; this merits their use over the other selected indicators in
this study. The indicator selected should be appropriate for the purpose it is being used
for, e.g. estimating prevalence of food insecurity versus monitoring the long term
impact of an intervention. There are other important criteria in the selection of an
indicator. Income data on a national scale has the advantage of being available annually
in South Africa, and this saves time and money. The 24HR vitamin A intake and 24HR
energy intake indicators has as its main draw back the skill and time needed to collect
and analyse the information, which increases cost and decreases sustainability. Dietary
diversity and hunger have the advantage of being simple to understand, and quicker and
easier to administer and analyse.
It is suggested that a national food security monitoring system in South Africa uses
more than one indicator, namely : 1) household income from already existing national
data, 2) the potential for including a hunger questionnaire in the census should be
explored, and 3) when further researched and validated, dietary diversity could also be
used in national surveys. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2006.

The current infant feeding practices and related factors of Zulu mothers with 0-6 month old infants attending PMTCT and non-PMTCT clinics in central Durban, KwaZulu-Natal : an exploratory study.Kassier, Susanna Maria. January 2005 (has links)
Abstract: Introduction:
Exclusive breastfeeding for the first six months of an infant's life is
recommended worldwide. In 1998 the South African Demographic and
Health Survey (SADHS) showed that only 10% of mothers exclusively
breastfeed at three months. As the HIV virus is transmissible via breast milk,
UNAIDS (2002) recommends that women in developing countries should be
given a choice of feeding method after being counselled on the risks and
benefits of breast feeding versus formula feeding. As a result, the Prevention
of Mother-to-Child Transmission (PMTCT) programme was launched in
KwaZulu-Natal with the aim of providing interventions to prevent Mother-to-Child
Transmission of the HIV virus. However, research has shown that infant
feeding practices are influenced by numerous factors. Ultimately mothers will
feed their infants in a manner they feel comfortable with, even if it is not
always the most appropriate choice.
Aim:
The aim of this study was to determine and compare current infant feeding
practices and some of the factors that influenced these practices among Zulu
mothers with 0 - 6 month old infants attending PMTCT and non-PMTCT
clinics in Central Durban, KwaZulu-Natal.
Methodology:
A cross-sectional, descriptive survey was conducted amongst 150 mothers
sampled from three non-PMTCT clinics and 150 mothers sampled from three
PMTCT clinics. Systematic random sampling of mothers attending the two
types of clinics was used to ensure an equal number of mothers· with infants
aged 0 - < 6 weeks, 6 - < 14 weeks and 14 weeks to 6 months. The number
of mothers interviewed per clinic was determined proportionate to clinic size.
Interviews were conducted in Zulu by trained fieldworkers according to a
structured interview schedule consisting of 87 open- and closed-ended
questions.
Summary of most important findings and conclusion:
Overall, one quarter of the mothers attending non-PMTCT and one third of
mothers at PMTCT clinics were practising exclusive breastfeeding at the time
of the survey. The general trend was that mothers attending PMTCT clinics
were more inclined than those attending non-PMTCT clinics to breastfeed
their infants exclusively (34% versus 24% respectively) or to formula feed
(16,7% versus 12,7% respectively). Furthermore, there was a significant
decline in exclusive breastfeeding and predominant breastfeeding with
increasing infant age in both clinic groups. The opposite held true for mixed
feeding and formula feeding in that infants were more inclined to mixed
feeding or formula feeding with increasing infant age. In both clinic groups,
exclusive breastfeeding was the method of choice in the 0 - < 6 week age
category, while a preference for mixed feeding was shown in the 6 - < 14
week category. This trend persisted in the 14 week - < 6 month age
category, especially in the non-PMTCT clinics, while there was a small but
pronounced increase in formula feeding amongst PMTCT mothers. Although
these findings can be explained as a result of implementing the PMTCT
programme, the positive trends observed in non-PMTCT clinics serve as an
indicator that the Integrated Nutrition Programme (INP) and Baby Friendly
Hospital initiative have also had an impact on the feeding choices mothers
make.
Despite the limited duration of the PMTCT programme at the time of the
study, indicators of the impact of the intervention include that a lower
percentage of PMTCT mothers introduced foods and/or liquids in addition to
breast milk to their infants before six months of age compared to non-PMTCT
mothers. Furthermore, more mothers attending PMTCT clinics were
shown how to breastfeed and were more likely to have received information
about formula feeding. Despite these indicators of a positive impact of the
PMTCT programme, the mean age for introducing liquids and/or solids in
addition to breast milk was about six weeks and the incidence of this practice
was very high for both groups. The similar incidence of formula feeding
observed between the two clinic groups suggests the presence of constraints
to safe infant feeding choices among mothers attending PMTCT clinics.
As observed, infant feeding practices were still not ideal in either of the two
clinic groups. However, the high level of antenatal clinic attendance
documented for both groups serves as evidence that, if opportunities for
providing mothers with appropriate infant feeding advice are utilized
optimally, the antenatal clinic could serve as an ideal medium through which
infant feeding education can take place, especially as the clinic-based nursing
staff were cited as the most important source of infant feeding information by
both groups of mothers in the antenatal and postnatal phases. The
documented infant feeding practices should be interpreted against the
backdrop of factors such as socio-demographic characteristics of the
mothers, availability of resources such as social support from peers and
significant others and reigning infant feeding beliefs that could influence
infant feeding decisions.
Predictors of exclusive breastfeeding in PMTCT and non-PMTCT clinics were
determined by means of multivariate logistic regression analysis. Significant
values were obtained for both clinic groups in terms of the infant not having
received liquids in addition to breast milk. No additional predictors were
found amongst mothers attending non-PMTCT clinics, however predictors
amongst mothers attending PMTCT clinics included whether the mother had
not visited the clinic since the infant's birth, whether she practiced demand
feeding and whether she was experiencing stress at the time of the study.
The limited number of predictors of exclusive breastfeeding documented in
this study, especially among non-PMTCT mothers may be explained by the
fact that infant feeding behaviour is multifactorial by nature and the
interaction between factors that influence feeding choice is strong. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2005.

Impact assessment of the integrated nutrition programme on child malnutrition in South Africa.Musvaire, Rufaro. January 2009 (has links)
The Integrated Nutrition Programme (INP) was implemented in 1995 to target child malnutrition
in South Africa. This study assessed the impact of the INP on child malnutrition by province and
age group using secondary data. Data from three national nutrition surveys, conducted in 1994,
1999 and 2005, were used to describe trends in child stunting, underweight, wasting, vitamin A
deficiency and iron deficiency. The relationship between the prevalence of the human
immunodeficiency virus (HIV) in prenatal women and child nutritional status; challenges and
constraints to implementing the INP at provincial level; and government responses to nutrition
recommendations by lead experts in the 1994 and 1999 surveys were also investigated.
Child nutritional status varied across provinces. In some provinces such as the Northern Cape,
stunting, underweight and wasting remained consistently high. Stunting decreased in the Eastern
Cape, but rates of wasting increased between 1994 and 2005. On the other hand, Gauteng and
the Western Cape generally had lower rates of malnutrition compared to the other provinces.
This may be due to these provinces being the most economically active in the country thus more
opportunities for employment and higher purchasing power of foods rich in micronutrients. By
2005, vitamin A deficiency had doubled in most provinces despite mandatory food fortification
being implemented in 2003. KwaZulu-Natal had the highest rates of vitamin A deficiency, while
Limpopo had the highest rates of iron deficiency. By 2005, malnutrition had decreased in
children aged seven to nine years, but had increased in those aged one to three years. There was
a significant positive correlation (p<0.01) between the prevalence of HIV in prenatal women and
vitamin A deficiency nationally. The prevalence of HIV in prenatal women was positively
correlated (p<0.05) with rates of wasting in children aged one to three years.
Limited skills, inadequate monitoring and evaluation, and limited infrastructure were common
challenges and constraints to implementing the INP at provincial level. The effect of HIV on
human resources and the higher demands of HIV infected patients also posed a challenge to
provinces as they implemented the INP. Government responded to most recommendations made by
nutrition experts. Supplementation,food fortification, growth monitoring and nutrition promotion
programmes were implemented. Based on the data, it would appear that INP activities targeted at
school-going children were more effective than those targeting children under-five. Although food
fortification was implemented in 2003, the vitamin A content of fortified products might not have
met legislative requirements. Additionally, because vitamin A is unstable to heat and light, if
vitamin A fortified foods are cooked or stored this may also influence the bioavailability of
vitamin A. Maternal HIV status might have attenuated child nutrition outcomes due to the negative
effect of HIV on related health conditions such as child caring and feeding practices. Some of
the challenges and constraints at provincial level might have negatively affected the
implementation of the INP and consequently its impact. Although government responded to most
recommendations made by nutrition experts, ongoing monitoring and evaluation of child
nutritional status were not adequately done, which might have also negatively affected INP
outcomes. In addition, factors in the macro-environment such as food inflation and access to
basic sanitation, could have lessened the impact of the INP on child malnutrition.
Interventions directed at malnutrition in children under-five need to be prioritised. There needs
to be rigorous monitoring of micronutrient content, especially vitamin A, of fortified foods.
Future studies need to include assessment of nutritional status in HIV affected and infected
children to help identify specific needs and develop appropriate policies. Frequent nutrition
surveillance to assess key child malnutrition indicators is required. / Thesis (M.Sc.) - University of KwaZulu-Natal, Pietermaritzburg, 2009.
