Background: Body mass index (BMI) and skinfold thickness are widely used to evaluate body composition. Information on patterns of skinfold thickness may help to understand changes in body composition during growth. The objectives of this study were to observe patterns of BMI, percentage body fat (%BF), and skinfold thicknesses of Indonesian children and adolescents aged 7-18 years.
Methods: Weight, height, and four skinfold thicknesses were measured in 2104 school children (924 boys, 1,180 girls) aged 7-18 years from Yogyakarta between 2015 and 2018. BMI and ratios between central and peripheral skinfold thicknesses were determined. %BF was predicted using the equation of Slaughter . Data were analyzed using analysis variance (ANOVA), independent sample t-test, and partial correlation (SPSS version 20.0).
Results: At 7-18 years, boys and girls showed a comparable gain in BMI. The comparable gain in %BF between boys and girls only occurred till age 10 and total skinfolds till age 11 years. While, %BF and skinfold thicknesses were higher in girls at 12-17 years, central to peripheral skinfold ratio were higher in boys. Partial correlation analyses showed that all skinfold thickness parameters and %BF were significantly correlated with BMI ( < 0.001; = 0.19-0.87).
Conclusions: The gain in BMI and skinfold thickness between the ages of 7 and 18 years occurred in age- and sex-specific patterns. Instead of comparable BMI, girls showed higher means of total skinfold thickness from age 12 years, while boys had higher central to peripheral adiposity ratio.

In recent years, significant advancements in respiratory and nutritional care have markedly improved the survival rates of preterm infants and enhanced long-term health outcomes. Despite these improvements, emerging research highlights the lasting impacts of early growth patterns on an individual's health trajectory. Adults born prematurely face a higher incidence of health issues related to their early birth.

Background: Malnutrition is a significant challenge in stroke patients, affecting both rehabilitation and independence. This study aims to evaluate whether early L-carnitine supplementation can effectively improve anthropometric parameters and malnutrition status in acute-phase ischemic stroke patients to mitigate the catabolic state.
Methods: Eighty-two first-ever ischemic stroke patients were randomly assigned to either the L-carnitine group (1000 mg three times/day for seven consecutive days) or the matching placebo group.

Background: Lower maternal insulin sensitivity during pregnancy is associated with greater fetal adiposity. Physical activity can improve insulin sensitivity, but it is not known if physical behaviours influence the known association of maternal insulin sensitivity with offspring adiposity. This study aimed to investigate the moderating impact of physical behaviours on this association.

Purpose: Researchers have predicted body fat percentage (BF%), as indicated by dual energy X-ray absorptiometry (DXA), from skinfold thicknesses in North American and European athletes, but not athletes from other regions. We sought to estimate an equation to predict BF% in elite Asian athletes from their skinfold thickness and girth measurements, with DXA as a reference method.
Methods: We collected data from two samples of athletes on Singaporean national teams.
Introduction: Body composition is studied in athletes as a means of measuring physical fitness and progression of training. Athletes can utilize body composition in multiple ways to guide training toward athlete specific goals. Several different methods exist with varying levels of cost, invasiveness, reading complexity, and availability.
