To investigate the determinants of overweight and obesity among 10- to 15-year-old schoolchildren in a population transitional phase North West Province South Africa.A cross-sectional survey was used weight status (anthropometric indicators) overweight/obesity including dietary intake, physical activity socio-economic status. A single, random sample (n=1257), stratified for gender, type school ethnic group, used. Data were collected on demographics, family circumstances, habitual activity,...
A range of psychophysical taste measurements are used to characterize an individual’s sweet perception and assess links between dietary intake. The aims this study were investigate the relationship four different perception, explore which measures relate food Forty-four women aged 20–40 years recruited for study. Four (detection recognition thresholds, intensity hedonic liking suprathreshold concentrations) assessed using glucose as tastant. Dietary included a four-day weighed record,...
ABSTRACT This cross-sectional, analytical study was a comprehensive health assessment focusing on dietary quality of 170 randomly selected elderly respondents in Sharpeville, South Africa. The methods included sociodemographic, food frequency questionnaire, 24 h-recall questionnaires, and anthropometric biochemical measurements. low mean±standard deviation (SD) diversity score (3.41±1.34) variety (4.77±2.2) compared with poverty parameters confirmed household insecurity this community....
Abstract Air displacement plethysmography ( ADP ) and dual‐energy X‐ray absorptiometry DXA are well‐regarded methods for predicting body fat percentage BF %). Bioelectrical impedance analysis BIA also predicts % has distinct advantages in research settings. Aim To assess the validity of against to measure %, test reliability each method. Methods Adults n = 166) with a wide range mass index (19–38 kg/m 2 were tested twice during 5‐day period. was conducted BodPod (Life Measurement Inc,...
An exploratory qualitative investigation was done to determine the feeding and weaning practices, knowledge attitudes towards nutrition of mothers/caregivers children up 3 years old attending baby clinics in Moretele district (South Africa).Qualitative data collection on six relevant topics using focus group interviews. Trained moderators, a pre-tested, structured interview schedule, interviewed participants age groups. Focus interviews were taped, transcribed translated. Content analysis...
ABSTRACT A trained sensory panel was used to establish terminology for describing the attributes of different cultivars orange‐fleshed sweet potato (OFSP) and white‐fleshed (WFSP). Quantitative descriptive analysis applied evaluate samples in terms aroma, texture, flavor aftertaste attributes. Thirteen were identified. Principal component (PCA) identify any factors differentiating between cultivars. The findings indicated that main differences were, PC1, density adhesive textural...
Ascorbic acid, and more recently, the carotenoids lutein zeaxanthin have been shown to enhance Fe absorption. However, it is not clear whether status improves when foods high in ascorbic acid are consumed with Fe-fortified meals. The present study aimed investigate consuming v. low acid-, lutein- zeaxanthin-rich fruit (gold kiwifruit banana) breakfast cereal milk improved women stores. Healthy aged 18–44 years ( n 89) stores (serum ferritin ≤ 25 μg/l Hb ≥ 115 g/l) were randomly stratified...
Obesity is a leading cause of morbidity and mortality, yet preventable. This study aimed to investigate associations between body mass index, fat percentage obesity-related eating behaviors. Women (n = 116; 18-44 years) were measured for height, weight using air displacement plethysmography (BodPod). completed the validated Three Factor Eating Questionnaire assess their behaviors Restraint, Disinhibition Hunger factor categories sub-categories. The behavior data analyzed with index...
Abstract Purpose The number of people living longer after a cancer diagnosis is increasing. Guidelines for survivorship recommend healthy diet and maintaining weight post-treatment. While survivors often express the need professional support nutrition management, few report seeing dietitian. This study aimed to explore primary care dietitians’ experiences, practices, perspectives in providing nutritional Australia. Methods qualitative used in-depth, semi-structured interviews with dietitians...
The unique composition of green kiwifruit has the potential to benefit CVD risk. aim present study was investigate effect consuming two kiwifruits daily in conjunction with a healthy diet on plasma lipids and other metabolic markers examine response according APOE genotype hypercholesterolaemic men. After undergoing 4-week diet, eighty-five men (LDL-cholesterol (LDL-C) > 3.0 mmol/l TAG < 3 mmol/l) completed an 8-week randomised controlled cross-over intervention sequences per d plus...
In New Zealand, there are few adequate food frequency questionnaires for assessing dietary intake. This study aimed to develop and assess the relative validity of a multi-nutrient, culturally appropriate, semi-quantitative questionnaire use in young adult Zealand women (the Women's Food Frequency Questionnaire (NZWFFQ)).Women (n = 110) aged 16-45 years Māori, Pacific or European ethnicity completed NZWFFQ intake over previous month, 4-day weighed record. Relative was evaluated by comparing...
Background/Objectives: To assess associations between dietary fibre intake, adiposity, and odds of metabolic syndrome in Pacific New Zealand European women. Methods: (n = 126) (NZ European; n 161) women (18–45 years) were recruited based on normal (18–24.9 kg/m2) obese (≥30 BMIs. Body fat percentage (BF%), measured using whole body DXA, was subsequently used to stratify participants into low (<35%) or high (≥35%) BF% groups. Habitual intake calculated the National Cancer Institute (NCI)...
Examining dietary patterns provides an alternative approach to investigating behaviors related excess adiposity. The study aim was investigate and body composition profiles of New Zealand European (NZE) women, participating in the women's EXPLORE (Examining Predictors Linking Obesity Related Elements) study. Post-menarche, pre-menopausal NZE women (16-45 years) (n = 231) completed a validated 220-item, self-administrated, semi-quantitative food frequency questionnaire. Body mass index (BMI)...
Obesity is a complex, multifactorial condition that an important risk factor for noncommunicable diseases including cardiovascular disease and type 2 diabetes. While prevention management require healthy energy balanced diet adequate physical activity, the taxonomic composition functional attributes of colonic microbiota may have supplementary role in development obesity. The metabolic capacity fecal 286 women, resident Auckland New Zealand, was determined by metagenomic analysis....
Background In South Africa, households living in informal urban settlements, rural areas, and on commercial farms experience various levels of dietary variety, food intake, household hunger. Low incomes, poor production availability, low spending power characterize these households. Households employ food-coping strategies to alleviate stress or availability. Objective To apply an existing strategy (FCS) index assess hunger its usefulness identifying the level patterns coping farm-worker...
The aim of this study was to explore associations between habitual dietary fibre intake, adiposity, and biomarkers metabolic health in Pacific New Zealand European women who are known have different disease risks. (n = 126) (NZ European; n 161) (18-45years) were recruited the PROMISE cross-sectional (1) based on normal (18-24.9kg/m2) obese BMI (≥30kg/m2). Body fat percentage (BF%), measured using whole body DXA, used stratify participants into low (<35%) or high (≥35%) BF% groups....
