The effect of seasonal food variety and dietary diversity on the nutritional status of a rural community in KZNNsele, Nelisiwe 07 August 2014 (has links)
Submitted in fulfillment of the requirements for the Degree Magister Technologiae: Consumer Science Food and Nutrition, Durban University of Technology, 2014. / Introduction: Dietary diversity is an indicator of access and measurement of household food security as it relates to income, location and seasonality. Dietary diversity is measured by physically counting the number of individual foods as well as food groups consumed over a given reference period. When dietary diversity is accurately measured, nutrient adequacy will be easily predicted. In order to measure dietary diversity accurately, it is important to determine household food security. Insufficient food and resources often result in food insecurity which leads to little or no dietary diversity. Poor populations suffer most from achieving dietary diversity because they consume a standard diet based on starchy staple food with limited fruits and vegetables resulting in multiple nutrient deficiencies. Rural communities rely on seasonal food variety in order to obtain fruits and vegetables needed by the body to limit nutrient deficiencies. Some seasons are more productive than others. Rural communities also use various coping strategies to deal with food insecurity in all four seasons. High levels of unemployment as well as a lack of nutrition education results in most rural households unable to cater for dietary diversity.
Aim: The aim of the study is to determine the effect of seasonal food variety, dietary diversity and nutrient adequacy on the nutritional status of women in rural areas.
Method: A hundred women in this community were weighed and measured and BMI determined and classified according to the WHO cut-off points for BMI. Waist circumference was measured in order to determine the waist-to-height ratio indication risk of metabolic syndrome. Twenty four hour recall questionnaires were used to determine actual intake compared to dietary reference intake (DRIs). Food Frequency Questionnaires for a period of seven days were completed captured and analysed using the SPSS version for descriptive statistics in order to determine food diversity. Coping strategies were determined by Focus Group interviews with community members in order to identify the various strategies used in time of food shortages. The severity of these strategies was determined by the community. Seasonal food consumption patterns and dietary intake behaviour were assessed over the four seasons. The highest frequency score (7) x severity weight (1-4) x10 strategies = maximum score of 140. Thus the higher the score the more food insecure the community is.
Results: Food production from crops differs in different seasons. Food insecurity is high in summer and autumn due to a low number of food items harvested from crops. The community cope less in summer and autumn due to less crops available. The community is more food insecure in spring and winter due to the high number of food items harvested from crops. The community cope better in winter and spring due to the high level of available crops. Anthropometric measurements indicated that 41.2% of women between 31 and 50 and 49% of women between 51 and 70 years of age had a BMI of 30 and above. About 44% of total women are obese and 29% are pre obese. Only 26% had a normal weight. The 24 hour recall analysis indicates that the high level of obesity is due to the fact that a high number of participants consume large amount of carbohydrates every day.
Conclusion: Overall results in this study indicated that this rural community is food insecure, on a higher level during summer and autumn, which leads to the consumption of undiversified diets. The women are malnourished and obese with a risk of metabolic syndrome. The information obtained in this study can be used to formulate strategies to develop interventions that can be used to access sufficient food in rural area in order to improve food insecurity, dietary diversity and, therefore, nutrient adequacy.

Food security and coping strategies of a rural community within the Valley of a Thousand HillsFelt, Leigh January 2014 (has links)
Submitted in fulfillment of the requirements for the degree Master Technology: Consumer Science Food and Nutrition, Durban University of Technology, Durban, South Africa, 2014. / Food security is a global concern and the insecurity thereof is prevalent in South Africa even though the country is deemed to be secure in terms of food availability.
The study was conducted to determine the socio-economic, health and nutrition and food security status of the community living in the Valley of a Thousand Hills in KwaZulu Natal, in addition to analysing their coping strategies.
Two hundred and fifty seven respondents were required to participate in this study. Data were collected by interviewing the respondents using pre-designed and pre-tested questionnaires; socio demographic questionnaires, dietary intake questionnaires- namely 24 hour recall and Food Frequency Questionnaire (FFQ) and the coping strategy questionnaires were used. Lastly anthropometric measurements were taken to determine BMI.
A prevalence of extreme poverty exists as a magnitude of the high unemployment rate, out of which 75.8% had been unemployed for more than 3 years. The household monthly income was less than R500 per month for 37.3% of the respondents. The mean Food Variety Scores (FVS) (±SD) for all foods consumed from the food groups during seven days was 22.45 (±10.32), indicating a low food variety score. In this study the food group diversity is summarized as the majority of the respondents (91.1%, n=226) being classified with a good dietary diversity score using 6-9 food groups. The mean of the three 24-Hour recall nutrient analysis indicated a deficient intake by both men and women in all of the nutrients (100% of the men and women could not meet the DRI’s for energy and calcium) except for the mean (±SD) carbohydrate intake by men aged 19-50 (214.71 ± 80.22). The main source of food intake was from the carbohydrate food group with an insufficient intake of animal products, dairy products and fruits and vegetables respectively; contributing to the macro and micro nutrient inadequacies.
Ninety six percent of this community experienced some level of food insecurity with the worst Coping Strategy Index food insecurity score being 117 out of a possible 175. Four percent of this community was classified as being food secure.
Overweight and obesity were the most exceptional anthropometric features by the women respondents with 26.5% (n=66) being overweight and 57% (n=142) obese. The men’s anthropometric features were predominantly normal weight.
This study has established poverty and unemployment as being the principal contributors for the food insecurity experienced by the populace and poor dietary intakes. The low food variety diet consumed by the respondents resulted in the DRI’s not achieved for most nutrients. The majority of the respondents only consumed two meals a day, as a coping strategy to reduce/prevent temporary food insecurity. Intervention strategies are needed to improve the food security status and dietary intake of the community members to overcome the crisis of malnutrition. / M
