Association between physical activity, nutritional status and cognitive performance among school children in southern Tanzania
Background: Physical activity is pivotal in promoting overall health and wellbeing, improving brain function and cognitive performance, and reducing risk of excessive weight and non-communicable diseases. Despite these benefits, physical inactivity among children and adolescents remains a global concern, particularly in low- and middle-income countries (LMICs). Only few studies have explored the association between physical activity, nutritional …
A Combined Physical Activity and Multi-Micronutrient Supplementation Intervention in South African Primary Schools
Background/Objectives : Declining physical activity (PA) and cardiorespiratory fitness (CRF) in children are global public health concerns, particularly in populations experiencing urbanization and economic transition. This study investigated the effects of a school-based intervention on PA, CRF, and cardiovascular disease (CVD) risk factors in children aged 6-12 years from marginalized communities in Gqeberha, South Africa. Methods : A cluster r…
Effect of a School-Based Physical Activity and Multi-Micronutrient Supplementation Intervention on Cognitive Function and Academic Achievement Among Schoolchildren in Tanzania
PA and MMNS interventions showed no significant cognitive or academic improvements versus placebo. Further research should optimize school-based nutrition and PA programs for improved learning outcomes
Effect of physical activity and multi-micronutrient supplementation on body composition among Tanzanian schoolchildren
The study was registered on 9 August 2018, with ISRCTN. https://doi.org/10.1186/ISRCTN29534081
Physical Activity, Sedentary Behaviour, Weight Status, and Body Composition among South African Primary Schoolchildren
Background: Over the past decades, childhood overweight has increased in many African countries. We examined the relationship between sedentary behaviour, moderate-to-vigorous physical activity (MVPA), and body composition in South African primary schoolchildren living in peri-urban settings. Methods: MVPA was measured via 7-day accelerometry and body composition via bioelectrical impedance analysis in 1090 learners (49.2% girls, M age = 8.3 ± 1.…
Moderate-to-Vigorous Physical Activity Is Associated With Cardiorespiratory Fitness Among Primary Schoolchildren Living in Côte d'Ivoire, South Africa, and Tanzania
Background: Physical inactivity and low cardiorespiratory fitness (CRF) are independent cardiovascular risk factors among children, but have rarely been investigated concurrently in sub-Saharan Africa. The purpose of this study was to compare physical activity (PA) and CRF of primary schoolchildren living in Côte d'Ivoire (CI), South Africa (ZA), and Tanzania (TZ), to test sex- and age-related differences, and to examine whether PA and CRF are as…
Prevalence of Stunting and Relationship between Stunting and Associated Risk Factors with Academic Achievement and Cognitive Function
Childhood stunting can have negative long-term consequences on cognitive development, academic achievement, and economic productivity later in life. We determined the prevalence of stunting and examined whether stunting and associated risk factors (low dietary diversity, insufficient hemoglobin, food insecurity, and soil-transmitted helminth (STH) infections) are associated with academic achievement and cognitive function among South African chil…
Physical Activity, Cardiorespiratory Fitness and Clustered Cardiovascular Risk in South African Primary Schoolchildren from Disadvantaged Communities
The coexistence of multiple cardiovascular risk factors has been reported in school-aged children from the age of nine years, but most evidence stems from high-income countries. This cross-sectional study aimed at describing the cardiovascular health risk, physical activity (PA) behavior and cardiorespiratory fitness (CRF) levels of South African primary schoolchildren, and at examining the associations between PA/CRF and a composite measure of c…
How are academic achievement and inhibitory control associated with physical fitness, soil-transmitted helminth infections, food insecurity and stunting among South African primary schoolchildren
Academic performance has been shown to be compromised in schoolchildren living in marginalised areas, compared to schoolchildren in less disadvantaged parts of South Africa. The present study suggests that cardiorespiratory fitness and grip strength are two potentially modifiable factors that are associated with children's academic achievement and cognitive performance, and that should be targeted in future school-based interventions
Health care cost of overweight-related diseases in Bangladesh
Objective: To estimate the economic burden of overweight in Bangladesh. Design: We used data from Household Income and Expenditure Survey, 2010. A prevalence-based approach was used to calculate the population attributable fraction (PAF) for diseases attributable to overweight. Cost of illness methodology was used to calculate annual out of pocket (OOP) expenditure for each disease using nationally representative survey data. The cost attributabl…
Prevalence and risk factors of vitamin D insufficiency and deficiency among 6–24-month-old underweight and normal-weight children living in an urban slum of Bangladesh
Objective We quantified the prevalence of vitamin D status in 6–24-month-old underweight and normal-weight children and identified the socio-economic and dietary predictors for status. Design Cross-sectional, baseline data from a nutritional intervention study were analysed. Multinomial logistic regression was used to estimate the odds of being vitamin D deficient or insufficient with the reference being vitamin D sufficient. Setting Urban slum a…
Double burden of underweight and overweight among Bangladeshi adults differs between men and women
Objective To estimate the prevalence of underweight and overweight among Bangladeshi adults and to determine if the double burden of underweight and overweight differs by gender and other socio-economic characteristics of individuals. Design We used data from the Bangladesh Demographic and Health Survey 2011. Multinominal logistic regression was used to examine associations between the different nutritional statuses of individuals and related det…
Beliefs and motives related to eating and body size
The findings from this study are helpful in the understanding of the reasons why strategies for the prevention and treatment of obesity may not be as effective as expected. The belief system of particular social groups within different SESs should be considered in order to understand the etiology of obesity and develop effective strategies
The effect of zinc supplementation on body composition and hormone levels related to adiposity among children
Objective To provide a comprehensive synthesis of the effects of Zn supplementation on childhood body composition and adiposity-related hormone levels. Design Five electronic databases were searched for randomized controlled trials of Zn supplementation studies published before 28 February 2015. No statistical pooling of results was carried out due to diversity in study designs. Setting Community- or hospital-based, from fourteen developing and d…
Food, eating and body image in the lives of low socioeconomic status rural Mexican women living in Queretaro State, Mexico
Energetic and nutritional regulation of the adaptive immune response and trade‐offs in ecological immunology
Ecological Immunology views immunocompetence as a costly process involving trade‐off decisions among competing nutrient demands by different life‐history traits. This review examines immunocompetence fitness costs in light of recent work on the role the energetic and nutritional status of the host plays in the regulation of the adaptive T‐helper lymphocyte response. Three phenotypically distinct T‐lymphocyte populations have been identified: the …
