Effect of school-based interventions on body composition of grade-4 children from lower socioeconomic communities in Gqeberha, South Africa

AbstractThis paper contains a narrative review of the literature in the field of school-based mind–body interventions (MBIs). The aim of the current review is to verify whether the school-based MBI programs implemented in primary and secondary schools over the past 5 years are effective in helping schoolchildren cope with stress-related, behavioral, and affective issues, as well as improve stress response and school performance. All articles were retrieved using a number of databases. Inclusion criteria comprised qualitative and quantitative, English language, and peer-reviewed studies among third graders (8–9 years old) to twelfth graders (17–18 years old), including special needs pupils. Qualitative studies were limited to pupils’ experience only. Ten studies meeting the criteria for this review were assessed. The school-based interventions included yoga-based programs and mindfulness training. Evidence was evaluated and summarized. Across the reviewed studies, we found support for MBIs as part of school curricula to reduce negative effects of stress and promote overall well-being with caveats to consider in choosing specific programs. The practical implications of the current review include considerations related to the incorporation of MBIs in school curricula, which would likely benefit schoolchildren.

Abstract Objective: To determine whether food security, diet diversity and diet quality are associated with anthropometric measurements and body composition among women of reproductive age. The association between food security and anaemia prevalence was also tested. Design: Secondary analysis of cross-sectional data from the Healthy Life Trajectories Initiative (HeLTI) study. Food security and dietary data were collected by an interviewer-administered questionnaire. Hb levels were measured using a HemoCue, and anaemia was classified as an altitude-adjusted haemoglobin level < 12·5 g/dl. Body size and composition were assessed using anthropometry and dual-energy x-ray absorptiometry. Setting: The urban township of Soweto, Johannesburg, South Africa. Participants: Non-pregnant women aged 18–25 years (n 1534). Results: Almost half of the women were overweight or obese (44 %), and 9 % were underweight. Almost a third of women were anaemic (30 %). The prevalence rates of anaemia and food insecurity were similar across BMI categories. Food insecure women had the least diverse diets, and food security was negatively associated with diet quality (food security category v. diet quality score: B = –0·35, 95 % CI –0·70, –0·01, P = 0·049). Significant univariate associations were observed between food security and total lean mass. However, there were no associations between food security and body size or composition variables in multivariate models. Conclusions: Our data indicate that food security is an important determinant of diet quality in this urban-poor, highly transitioned setting. Interventions to improve maternal and child nutrition should recognise both food security and the food environment as critical elements within their developmental phases.

Regular exercise during school hours is encouraged since childhood obesity has reached epidemic proportions. Moreover, a great majority of adolescents do not meet the recommendations for moderate-to-vigorous physical activity. The present study aimed to determine the effects of school-based high-intensity interval training (HIIT) and nutrition intervention on body composition and physical fitness in overweight adolescent girls. Forty-eight girls were included in the study, of whom 24 (age = 15.5 ± 0.7 years) were randomized to a experimental group (EXP) (HIIT and nutrition intervention school-based program) and 24 (age = 15.7 ± 0.6 years) to a control group (CON) that maintained their usual physical education activities. HIIT consisted of 10 stations of own bodyweight exercise and was done three times per week for eight weeks. Moreover, the EXP participated in the nutrition program led by a nutritionist two times a week. Apart from body composition assessment, participants performed countermovement jump (CMJ), medicine ball throw, hand-grip test, and Yo-Yo Intermittent Recovery Level 1 Test (YYIRT1). A significant effect of group (EXP vs. CON) x time (pre vs. post) interaction was observed for weight [F(1,44) = 7.733; p = 0.008], body mass index [F(1,44) = 5.764; p = 0.020], body fat (in kg) [F(1,44) = 17.850; p < 0.001], and body fat (in %) [F(1,44) = 18.821; p < 0.001]. Moreover, a significant interaction was observed for the medicine ball throw [F(1,44) = 27.016; p < 0.001] and YYIRT1 [F(1,44) = 5.439; p = 0.024]. A significant main effect for time was found for hand grip [F(1,44) = 9.300; p = 0.004] and CMJ [F(1,44) = 12.866; p = 0.001].The present study has demonstrated that just eight weeks school-based HIIT and nutrition intervention, including three sessions a week, can improve body composition and muscular and physical aerobic performance in overweighted adolescent girls.
