Background: Birth weight is considered an important marker of inadequate maternal nutrition, and it is a critical indicator of the newborn's health and development., Objective: This study evaluated the influence of low birth weight (LBW) on body composition in 7-10-year-old school children from Boane City-Mozambique., Methods: A total of 220 children (female = 122 and male = 98) were divided into two groups according to their birth weight (LBW, n = 41; and normal birth weight, NBW, n = 179). Anthropometric indicators of nutritional status were analyzed by the indices weight-for-age, height-for-age, BMI-for-age, and weight-for-height., Results: LBW children showed reduced skinfolds, and weight-for-height when compared to NBW children. Birth weight was positively associated with all anthropometric variables, except for BMI, which was not associated with any other variable. The r 2 value ranged from .09 (weight-for-age) to .72 (height-for-age). For body composition variables, older children had higher fat mass (β = .26; 95% CI = 0.05-0.48) and fat-free mass (β = 1.10; 95% CI = 0.71-1.48), and boys had lower fat percentage (β = -3.49; 95% CI = -4.35 to -2.65) and fat mass (β = -.92; 95% CI = -1.31 to -0.55) than girls. Birth weight was also positively associated with fat-free mass., Conclusion: LBW seems to influence some growth indicators of children living in Boane, however, current environmental factors seem to weaken this association. Our results suggest that public policies involving healthy nutrition and physical activity can reverse the effects of low weight in children from Boane., (© 2024 Wiley Periodicals LLC.)

Background: Physical activity plays an important role on children with obesity. This study evaluated the effects of plyometric training on the anthropometry, body composition, and the blood pressure (BP) and heart rate (HR) of boys with obesity., Methods: Boys aged 7 to 9 years old were divided in: non-trained (N.=12) and trained (N.=29). The plyometric training program consisted of jumps on nonconsecutive days for twelve weeks. Anthropometry and body composition, BP and HR were evaluated. BP, HR and rate-pressure product were recorded at rest and 2 minutes after the section. Two-way repeated factors ANOVA was used., Results: Trained group had a reduction in skinfolds and an increase in free fat mass (within and between-groups) and a large effect size for most anthropometric and body composition variables. Late systolic response was reduced from 122±1.1 (immediately post-exercise at the first week) to 112±1.0 at the end of plyometric training period. Diastolic reduction was seen two minutes after each session of exercise (from 68±1.1 to 62±1.2). HR was reduced in response to plyometric training (108 bpm to 97 bpm)., Conclusions: Our findings strengthen previous studies that suggest that intense exercise has significant adaptive effects on BP and HR.

Background: Overweight/obesity during adolescence in lower-middle income countries has become a public health problem with consequences in adulthood. Inadequate dietary habits, poor diet quality, sedentary behavior, and parental obesity have been reported., Objective: To describe management of obesity-like food habits and behavior of adolescents from lower-middle income countries with respect to what keeps them using this diet (barriers) and what helps them avoid it (enablers)., Methods: Systematic review of the literature related to obesity and food intake of adolescents conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA)., Results: We classified 11 eligible studies describing the barriers to and enablers of the management of obesity-like food intake and obesity lifestyle. The dual burdens of malnutrition and increased urbanization have been observed. There is preference for processed food, dietary habits, and obesity-like food intake and sedentary behavior. Barriers to managing body weight gain included mostly consumption of fast-food and snack food, less vegetable and fruit intake, skipping meals, and sedentary behavior. Enablers of managing body weight gain included changes in nutritional habits, perception of the consumption of healthy food, physical activity, and engagement in programs to change lifestyle., Conclusion: The globalization of the fast food industry has provided an obesogenic environmental stimulus for adolescents in lower-middle income countries.

Objective: To evaluate associations between low birth weight (LBW) and anthropometry, body composition, physical fitness, and gross motor coordination among schoolchildren from Maputo, Mozambique., Methods: A total of 353 children aged 7 to 10 years old from both genders born in Maputo (Mozambique) were sampled. The sample was divided into two groups: LBW (n = 155) and normal birth weight (NBW, n = 198). Body composition measurements and indices weight-for-age, height-for-age, and weight-for-height were assessed. Physical fitness was assessed by handgrip strength, flexibility, agility, long jump, and running speed. Gross motor coordination was evaluated by using the Korper Koordination Test fur Kinder (KTK) battery., Results: LBW children were lighter and smaller than NBW children with reduced indices for weight-for-age and height-for-age. They also showed a reduced performance in handgrip strength and sideways movement tests. These differences remained significant even after adjustment for age, gender, body size, and fatness skinfold thickness., Conclusion: LBW seems to be the major factor that influences anthropometry, and is a predictor of low muscle strength and low performance on sideways movement tests. This result suggests that growth faltering in LBW children is associated with adverse health consequences, even after controlling for gender, age, fatness, and body size., (© 2017 Wiley Periodicals, Inc.)

Low birth weight (LBW<2500), very low birth weight (VLBW<1500), extremely low birth weight (ELBW<1500) infants are at high risk for growth failure that result in delayed development. Africa is a continent that presents high rates of children born with LBW, VLBW and ELBW particularly sub-Saharan Africa. To review the existing literature that explores the repercussions of LBW, VLBW and ELBW on growth, neurodevelopmental outcome and mortality in African children aged 0-5 years old. A systematic review of peer-reviewed articles using Academic Search Complete in the following databases: PubMed, Scopus and Scholar Google. Quantitatives studies that investigated the association between LBW, VLBW, ELBW with growth, neurodevelopmental outcome and mortality, published between 2008 and 2015 were included. African studies with humans were eligible for inclusion. From the total of 2205 articles, 12 articles were identified as relevant and were subsequently reviewed in full version. Significant associations were found between LBW, VLBW and ELBW with growth, neurodevelopmental outcome and mortality. Surviving VLBW and ELBW showed increased risk of death, growth retardation and delayed neurodevelopment. Post-neonatal interventions need to be carried out in order to minimize the short-term effects of VLBW and ELBW.
