Socioeconomically deprived children are at increased risk of ill-health associated with sedentary behavior, malnutrition, and helminth infection. The resulting reduced physical fitness, growth retardation, impaired cognitive abilities may impede children's capacity to pay attention. present study examines how socioeconomic status (SES), parasitic worm infections, stunting, food insecurity, fitness selective attention academic achievement in school-aged children.The cohort included 835...
As traditional lifestyle and diets change with social economic development, disadvantaged communities in low- middle-income countries increasingly face a double burden of communicable non-communicable diseases. We studied the relationship between physical fitness infections soil-transmitted helminths (STHs), intestinal protozoa Helicobacter pylori among schoolchildren Port Elizabeth, South Africa.We conducted cross-sectional survey 1009 children, aged 9 to 12 years, from eight primary...
Objectives To evaluate the effect of a 20-week school-based physical activity intervention program on academic performance and selective attention among disadvantaged South African primary school children. Design Cluster randomized control trial. Methods The study cohort included 663 children from eight schools, aged 8–13 years. Data assessment took place between February 2015 May 2016 following implementation program. d2 test was employed to assess attention, while averaged end-of-year...
Obesity-related conditions impose a considerable and growing burden on low- middle-income countries, including South Africa. We aimed to assess the effect of twice 10-week multidimensional, school-based physical activity intervention children’s health in Port Elizabeth, A cluster-randomised controlled trial was implemented from February 2015 May 2016 grade 4 classes eight disadvantaged primary schools. Interventions consisted education lessons, moving-to-music classes, in-class breaks school...
Background: Over the past decades, childhood overweight has increased in many African countries. We examined relationship between sedentary behaviour, moderate-to-vigorous physical activity (MVPA), and body composition South primary schoolchildren living peri-urban settings. Methods: MVPA was measured via 7-day accelerometry bioelectrical impedance analysis 1090 learners (49.2% girls, Mage = 8.3 ± 1.4 years). The relationships behaviour with various indicators (body fat fat-free mass [total,...
Childhood stunting can have negative long-term consequences on cognitive development, academic achievement, and economic productivity later in life. We determined the prevalence of examined whether associated risk factors (low dietary diversity, insufficient hemoglobin, food insecurity, soil-transmitted helminth (STH) infections) are with achievement function among South African children living marginalized communities. A cross-sectional sample 1277 (aged 5–12 years) was analyzed. Stunting...
Abstract Background In low- and middle-income countries, infectious diseases remain a key public health issue. Additionally, non-communicable are rapidly growing problem that impose considerable burden on population health. One way to address this dual disease burden, is incorporate (lifestyle) promotion measures within the education sector. planned study, we will (i) assess compare physical activity, fitness, micronutrient status, body composition, infections with soil-transmitted...
An in-depth epidemiological investigation on intestinal parasite infections in an impoverished area of Port Elizabeth, South Africa provides a unique opportunity for research its impact children's physical fitness, cognitive performance and psychosocial health. Additionally, we will screen risk factors the development diabetes hypertension adulthood. A 2-year longitudinal cohort study be conducted, consisting three cross-sectional surveys (baseline two follow-ups), eight historically black...
Chronic diseases of lifestyle in South Africa are on the increase, as shown by recent studies. Black women, who have country’s highest levels inactivity, overweight and obesity, particularly at risk. This study used qualitative methods to investigate barriers physical activity participation two generations professional women (teachers, nurses, social workers public managers). The reflect pre- post-democracy age groups Africa. older generation (n=20), aged 35 45 years, spent their formative...
Abstract Background The prevalence of overweight and obesity is increasing among African children potentially predisposing them to greater non-communicable diseases (NCDs) in adulthood. This risk may be higher growth-impaired who have fat mass. Therefore, we examined the effects school-based physical activity (PA) promotion multi-micronutrient supplementation (MMNS) on body composition South enrolled a longitudinal randomized controlled trial. Methods Children were cluster-randomized by...
Low- and middle-income countries are facing a dual disease burden with infectious diseases (e.g., gastrointestinal tract infections) non-communicable diabetes) being common. For instance, chronic parasite infections lead to altered immune regulatory networks, anemia, malnutrition, diarrhea an associated shift in the gut microbiome. These can all be pathways of potential relevance for insulin resistance diabetes. The aim this study was investigate association between common glycemia children...
Albendazole is one of two standard drugs for the control soil-transmitted helminthiasis. A total 149 schoolchildren from Port Elizabeth, South Africa, were examined helminth infections using duplicate Kato-Katz thick smears before and 2 weeks after administration albendazole (400 mg). Trichuris trichiura was predominant species (prevalence 60.4%), followed by Ascaris lumbricoides (47.7%). While highly efficacious against A. (cure rate [CR] 97.2%; egg reduction [ERR] 94.3%), it lacked...
Increased health risks associated with physical inactivity in the Black population have been reported recent years. women, suffering highest levels of inactivity, overweight and obesity, are at greatest risk developing chronic diseases lifestyle. This explorativedescriptive study investigated activity patterns status two generations professional reflecting pre-democracy post-democracy age groups. Quantitative measures were used, including ActiGraph GT1M accelerometer, Global Physical...
Physical inactivity (PIA) is a growing global health problem and evidence suggests that PIA key driver for cardiovascular chronic diseases. Recent data from South Africa revealed only about half of the children achieved recommended daily physical activity (PA) levels. Assessing intensity PA in low socioeconomic communities low-income middle-income countries important to estimate extent risk overall impact on health.We conducted cross-sectional survey eight quintile 3 primary schools...
Hypertension and overweight are growing public health concerns in school-aged children. We examined whether cardiorespiratory fitness sport participation contribute to the prevention of hypertension overweight. conducted a cluster-randomized controlled trial with 853 children aged 8–13 years eight primary schools Port Elizabeth, South Africa. Cardiorespiratory fitness, participation, body mass index, blood pressure were assessed at baseline after physical activity intervention, which took...
The burden of poverty-related infectious diseases remains high in low- and middle-income countries, while noncommunicable (NCDs) are rapidly gaining importance. To address this dual disease burden, the KaziBantu project aims at improving promoting health literacy as a means for healthy active lifestyle. implements school-based intervention package consisting physical education, moving-to-music, specific nutrition education lessons from KaziKidz toolkit. It is complemented by KaziHealth...
Introduction Risk factors for noncommunicable diseases such as insufficient physical activity (PA), overweight or hypertension are becoming increasingly predominant among children globally. While school-based interventions promising preventive strategies, evidence of their long-term effectiveness, especially vulnerable populations, is scarce. We aim to assess the short-term effects and health KaziKidz intervention on cardiometabolic risk long-term, pre-and post-COVID-19 pandemic changes...
Introduction Regular physical activity is associated with multiple health benefits for children. Evidence from cross-sectional studies suggests that positively health-related quality of life (HRQoL). The promotion activity, and hence HRQoL, through a school-based intervention therefore an important endeavor, particularly in disadvantaged areas low- middle-income countries, including South Africa.
