Measurement and description of cigarette smoking and weight reducing behaviors in female adolescents.Benedict, Jamie Ann January 1990 (has links)
Ethnographic interviews with female adolescents were used to develop summated-rating scales to measure cigarette smoking and weight-reducing behaviors. The Cigarette Smoking Scale is based on the frequency that one smokes cigarettes rather than the number of cigarettes smoked, and includes items related to the subjective and addictive effects of nicotine, social cues for cigarette smoking, and situational opportunities to smoke. The Dieting Patterns Scales measure the frequency of employing three different types of weight-reducing strategies; exercise and a "healthy" diet, skipping meals and fasting, and the use of diet pills and diet drinks. The scales were found to be: (a) sensitive to group differences, indicating construct validity, (b) stable, and (c) internally consistent. The Cigarette Smoking Scale and Dieting Patterns Scales were used to examine the relationships among cigarette smoking, weight-reducing behaviors, dietary intake, maturation, and body composition of 129 eighth-, tenth-, and twelfth-grade girls. Two-thirds of girls included in this study reported dieting to lose weight within the past year. This behavior was associated with a lower energy intake, a higher body mass index, and lower socio-economic status. Both dieting and frequency of employing different types of weight-reducing strategies were consistent across school grades. The importance of measuring both the frequency and type of weight-reducing strategy was indicated by the distinct relationships noted among the Dieting Patterns Scales, dietary intake, and body mass index. The use of diet pills and diet drinks was associated with significantly lower energy, macronutrient, calcium, iron and riboflavin intake. Skipping meals and fasting was unrelated to energy intake but positively related to vitamin C and folacin intake. Lastly, exercise and "healthy" diet behaviors were related to a higher intake of dietary fat. Cigarette smoking was unrelated to weight-reducing behaviors and dieters were not more likely to smoke than non-dieters. However, smokers were thinner. Teens' knowledge and/or beliefs regarding the effects of smoking on body weight may help define the relationship between smoking and dieting.

Dietary intakes of twenty-six preadolescent girlsGee, Frances Walmsley January 1958 (has links)
The purpose of this experiment was to study the self-selected dietary intakes and some of the food practices of twenty-six preadolescent girls as determined from two-week dietary records and to compare the calculated self-selected intakes with Recommended Dietary Allowances of the National Research Council.
Subjects between the ages of seven and nine years and in the height-weight range considered normal for this sex-age group were chosen. After different methods of dietary survey were considered the two-week record of food intake was used. Forms and instructions for recording data were given to the mothers and they recorded foods consumed by the subjects in household measurements. Nutrient intakes for each subject were calculated using United States Department of Agriculture Handbook Number 8.
The mean dietary intakes for all subjects were equal to or above allowances of the National Research Council. The seven year old group had higher nutrient intakes than the eight or nine year old groups.
Food habits were studied. The consumption of about a quart of milk per day per subject and the practice of eating substantial breakfasts were practices to which credit was due for above average rating in nutrient intake.
Since girls in this study were to be subjects in a metabolism balance study to follow, it was imperative that their typical food intakes be at least equal to and compare favorably with the average for this age group. Their dietary histories and their physical examinations proved them to be entirely acceptable. / Master of Science

Nutrition knowledge, disordered eating, and body dissatisfaction among middle school femalesMack, Jennifer E. January 2001 (has links)
The purpose of the study was to better understand nutrition knowledge, disordered eating and body dissatisfaction among middle school females, in hopes of disseminating this information to parents, teachers, and others with an interest in the well-being of young women. The design of the study determined prevalence of disordered eating and body dissatisfaction, and the level of nutrition knowledge among middle school females. 134 subjects completed a 66-item questionnaire. Descriptive statistics along with an independent t-test, chi square, and Pearson product moment correlation coefficient were used to analyze the data. Prevalence of disordered eating among 7th graders was 18.8%, and 15% for 8" graders. High levels of body dissatisfaction were observed in 35% of 7"' graders and 26% of 8t' graders. A significant relationship was found between nutrition knowledge and disordered eating (r=-.309). There was no statistically significant difference between 70' and 8th graders for either disordered eating or body dissatisfaction. / Department of Physiology and Health Science

Separation and quantitation of the seven forms of vitamin B-6 in plasma and 4-pyridoxic acid in urine of adolescent girls by reverse phase high performance liquid chromatographyChrisley, Barbara Mc January 1988 (has links)
The vitamin B-6 status of seemingly healthy adolescent girls was determined using several accepted and proposed parameters in an effort to establish guidelines for status evaluation. HPLC-derived plasma B-6 vitamer [pyridoxal phosphate (PLP), pyridoxine phosphate (PNP), pyridoxamine phosphate (PMP), pyridoxal (PL), pyridoxine (PN), and pyridoxamine (PM)] and 4-pyridoxic acid (4-PA) concentrations and urinary 4-PA levels of 28 white adolescent females, 12-15 years, having radiomonitored plasma PLP concentrations and coenzyme stimulation of erythrocyte alanine aminotransferase activities indicative of adequate status were determined. Mean daily vitamin B-6 and protein intakes of the subjects were 1.48 mg and 78.3 g, respectively. The ranges for plasma B-6 vitamer and 4-PA concentrations for these subjects which had seemingly adequate vitamin B-6 status were as follows: (nmol/L) PLP, 40.9-122.2; PNP, 0-16.1; PMP, 0-8.1; PL, 0- 15.0; PN, 0-21.9; PM, 0-17.8; and 4-PA, 0-55.7. PLP was the predominant plasma B-6 vitamer as well as being the only vitamer found in plasma of all subjects. Urinary 4-PA concentrations of the girls ranged from 0.11-2.50 pmol/mmol creatinine. The B-6 vitamer values of these white adolescent girls should be of use in the establishment of normal ranges for vitamin B-6 status parameters. HPLC methodologies seem to be advantageous for the rapid and accurate assessment of vitamin B-6 status. / Ph. D.

Determining the contribution of lunchbox content to the dietary intake of girls (13-18 years old) in a high school in LindelaniHlambelo, Nomakhosazana 30 July 2013 (has links)
Dissertation submitted in fulfilment of the requirements of the Degree of Magister
Technologiae: Food and Nutrition, Durban University of Technology, 2012. / There is lack of data on the dietary intake and patterns of Lindelani adolescents, which
necessitates comprehensive nutritional assessment.
Objectives: The objectives were to investigate the dietary intake and nutritional analysis of
lunchbox contents of high school girls (13 -18 years of age) in Lindelani and evaluate its
contribution to their dietary intake.
Methodology: The study was of a descriptive nature with an analytical component, a
convenience sample of 61 learners who brought lunchboxes from home and completed a
socio- demographic questionnaire, QFFQ and two 24- hour recall questionnaire used for
evaluation of their dietary intake. Anthropometric measurements, including body
composition, were performed.
Anthropometric data were captured on a Microsoft Excel
spreadsheet and displayed on WHO growth charts to determine stunting, wasting,
underweight and over-weight. . Lunchboxes were required and collected without informing
participants to avoid bias, each lunch box was weighed and the content recorded and analysed
using Food Finder 3 computer software program. It was analysed by selecting the mean
intake of the group and comparing it to the Daily Recommended Intake (DRIs) for this group
of individuals.
Results: The results indicated that the food group most commonly consumed was
carbohydrates. The lunchbox mean energy content was 90.14 kJ (>100% of DRIs) which is a
big portion for a lunchbox since there are other meals of the day to be eaten too. The mean
intake of fruit portion consumed was 135g which was only consumed by 1% in the top 20
food items compared to 141.82g consumed by 18% in 24- hour recall. Bread, margarine and
polony were commonly consumed in QFFQ, Lunchboxes and 24- hour recall. Fat
consumption for lunchboxes was 34.04% higher than the WHO nutrient intake goal which
put these teenagers at risk of overweight. Fruit and vegetable intake was 106.95g (QFFQ),
107.27g (24-hour recall) and 109.49g (mean lunchbox content). This indicates poor intake of
fruit and vegetables, being far lower than WHO recommendation of 400g per day. Dietary
fibre was also found below 25g.
Conclusion: Although the group seemed to consume all the nutrients but it is a small sample
of the population. The study indicated that the majority of the respondents consume mostly
IVcarbohydrate diets and the lunchboxes did not meet the basic requirements of a balanced diet.
The lunchboxes contributed on average one third of the girl’s daily food intake.

Nutritional status and dietary intake of adolescent girls in Mandlenkosi High School, LindelaniSilangwe, Beauty Nontuthuzelo 30 July 2013 (has links)
Dissertation submitted in the fulfilment of the requirements for the Degree of
Magister Technologie: Food and Nutrition, Durban University of Technology, 2012. / Background: Assessing the nutritional status of adolescents could be a catalyst in addressing
malnutrition at an early age and at a school level.
Objectives: The study was conducted to examine the nutritional status and dietary pattern of
adolescent girls attending school in Lindelani, KwaZulu-Natal.
Methods: Adolescent girls were selected from a randomly selected high school. A total of
157 adolescent girls aged 13 to 18 years were surveyed for socio-demographic indicators,
nutritional status and dietary intake. Data were collected by interviewing the adolescent girls
and the parents using pre-designed and pre-tested questionnaires. Weight and height were
measured and socio-demographic data collected by means of a questionnaire. Dietary intake
data were gathered by using two 24hr recall questionnaires and a QFFQ.
Results: The findings indicated that adolescent girls in Lindelani face two distinct nutrition
situations, underweight and overweight. The nutrient intake was compared with the dietary
reference intake (DRI). The prevalence of undernutrition (7.6%) among the participants
assessed as stunting (height-for-age) was based on the usual pattern of food intake. The
results revealed that 92.4% of the girls were of normal height for age (>-1SD to +3SD),
10.8% were overweight (>+2SD to <+3SD) and 1.9% were obese (>+3SD). Consumption of
high carbohydrates based food items was prevalent and carbohydrate intake correlated
positively with the BMI-for-age Z-score. The income of the household was assessed,
however, there was no statistically significant correlation (p=0.442) between BMI-for-age (Z-
scores) and the caregivers level of income. For the intake of protein and dietary fibre, at least
40 and 144 participants, respectively, did not meet the dietary recommended intake measured
by the 24hr recall. The study explains that not only is there under and over nutrition in this
group but also inadequate micronutrient intake, especially of essential nutrients such as
vitamin A, vitamin C, iron and calcium. A substantial proportion of the girls did not consume
adequate folate. The households that reported to have had adequate food at all times were
only 29.3%.
Conclusion: The results show a lack of dietary variety, which may contribute to the nutrient
deficiency. Both undernutrition and overnutrition was prevalent among the girls. The
majority of the population had a lower energy intake than recommended. Intervention
strategies are needed to improve the dietary intake of adolescent girls and overcome the crisis
of malnutrition.

Relationship between physical activity with dietary intake and nutritional status of adolescent girls attending a private school in DurbanWatson, Roxanne January 2017 (has links)
Submitted in fulfilment of the qualification of Master's Degree in Food and Nutrition, Durban University of Technology, 2017. / Aim
The purpose of this study was to investigate the nutritional status of adolescent girls attending a private high school in Durban and included an investigation of what food the girls consumed on a daily basis and an account of physical activity they participated in within a one-week period to determine a relationship between the variables.
Methods
Adolescent girls were selected as part of a convenience study at a private high school. A total of 225 adolescent girls aged 13-18 years were surveyed for nutritional status and dietary intake as well as physical activity levels. The parent/ caregiver of each girl who participated was interviewed to ascertain socio-demographic indicators. Data was collected by interviewing the adolescent girls and the parents/ caregivers using pre-designed and pre-tested questionnaires. Weight and height were measured, physical activity levels were identified through the use of a physical activity questionnaire and socio-demographic data was collected by means of a questionnaire. Dietary intake data was gathered over two week days and one weekend day by using a 24-hour recall questionnaire and a food frequency questionnaire (FFQ).
Results
The majority of the participants were from well-off, financially stable families with good living conditions and well-educated and employed parents/ caregivers who provided a more than adequate variety of food and regular meals every day. The girls were of normal BMI (72.2%) and collectively had a mean BMI of 21.9, lower than the South African national average found for adolescent girls. There was a surprising number of underweight individuals (12.6%) as compared to overweight girls (10.3%). Furthermore, 99.6 percent of the girls were of normal height-for-age (≥-2 <+3SD) but were consuming far less energy than is required for the allocated age category. Energy came from the normal recommended macronutrient range with fat being on the borderline higher end of the normal range and carbohydrates coming from the lower end of the normal range; protein sources were adequately consumed. Fruit and vegetable consumption was reported to be very low subsequently leading to the poor dietary fibre intake identified across the sample group. Supplementation is taken by nearly a third (32.7%) of the girls which may contribute to their overall nutritional wellbeing. Among the top twenty foods consumed, milk, sugar, bread, tea and lettuce were the top five foods in the order stated. Although a wide variety of foods was consumed across all nine food groups over a week period, a mean daily DDS was lower but still adequate with 5.5 and the quantity of foods consumed were not of a substantial enough amount leading to poor total energy consumed and some micronutrient levels such as calcium, magnesium and folate not being met.
All the participants were seen to be fairly physically active, performing a wide variety of sporting activities during school time and after school hours. The girls completed on average 199.64 minutes (SD±134.97) of physical activity per week, which is less than half of the WHO recommended physical activity minutes per week for adolescents. Significant correlations were seen between BMI and physical activity done on the weekend (p=0.041) and BMI and the amount of money spent on food per month (p=0.016) as well as extremely significant correlations between BMI and the number of minutes spent performing physical activities per week (p=0.002), as well as BMI and the amount of sport done over a one week period (p=0.005).
Conclusion
The results confirm that a relationship does exist between the physical activity levels and nutritional status of the adolescent girls surveyed. The majority of the population had low physical activity levels as well as low energy intake, which was supported by an inadequate quantity of food items consumed; however, anthropometric measurements showed to be majority within normal parameters with cases of underweight girls being more prominent than overweight which may suggest that over- and/ or under-reporting may have occurred. A high dietary diversity indicated a higher nutrient intake suggesting the importance of a diversified diet. / M

Low income African American adolescent girl's eating choicesJenkins, Sandra Kay, 1956- 28 August 2008 (has links)
The aim of this exploratory qualitative study is to identify the problems African American adolescent girls face in making eating choices and to learn how they make decisions about eating. Differences related to culture and socioeconomic status influences, and decision-making strategies were explored. Three sites in African American communities were selected for focus groups and individual adolescent girl-parent dyad interviews for data collection. Data were gathered in 5 focus groups and 4 individual adolescent girl-parent dyad interviews with African American adolescents (n=30). Bronfenbrenner's Ecological Systems Theory (EST) provided the conceptual framework for informing the analysis and interpretation of the data. Using grounded theory methods, the researcher identified the core variable or basic psychosocial problem that faced the participants was receiving mixed messages. Low income African American adolescent girls receive mixed messages about nutrition, health and foods from their microsystems that are comprised of friends and family, and from macrosystems that include textbooks and the media. Filtering the mixed messages is the basic psychosocial process that low income African American girls use to handle the barrage of mixed messages they receive from their microsystems and macrosystems regarding eating choices and exosystem influences. The process of filtering the mixed messages is comprised of five phases: Applying a lens, surveying available resources, weighing influences, then choosing alternating eating strategies and evaluating their eating choices. How the adolescent girl applies a lens, surveys resources and weighs the influences together impact the alternating eating strategies that they implement. Over time they evaluate the effectiveness of their eating choices. / text
