Objective Associations between self-reported sleep duration and obesity indices in children are well recognised; however, there are no studies on associations between objectively measured other sleep parameters and physical activity with body composition in preschoolers. Therefore, the aim of this study was to determine the associations between sleep parameters and moderate-to- vigorous physical activity (MVPA) with body composition indices in preschoolers using objective measures. Design A cross-sectional study. Participants The study group consisted of 676 children aged 5–6 years, who were enrolled in kindergartens in the 2017/2018 school year. Outcome measures Sleep parameters and MVPA were measured using accelerometers for 7 days. Bioelectrical impedance analysis was used to estimate body composition. Results Sleep duration and sleep efficiency were inversely associated with body fat percentage (BFP) (β=−0.013 and β from –0.311 to −0.359, respectively) and body mass index (BMI) (β from −0.005 to −0.006 and from −0.105 to –0.121, respectively), and directly associated with fat-free mass (FFM) (β from 0.010 to 0.011 and from 0.245 to 0.271, respectively) and muscle mass (β from 0.012 to 0.012 and from 0.277 to 0.307, respectively) in unadjusted and adjusted models. BFP was inversely associated with MVPA and positively associated with number of awakenings and sleep periods. Number of sleep periods was inversely associated with FFM, and positively with BMI and muscle mass. Correlation matrix indicated significant correlation between BFP, FFM and muscle mass with sleep duration, sleep efficiency, number of sleep periods and MVPA. Conclusions Periodic assessment of sleep parameters and MVPA in relation to body composition in preschool children may be considered, especially in those who are at risk for obesity.

Introduction. In recent years there has been a significant increase in the prevalence of overweight and obesity in humans. It turns out that the problem is not limited to adults; excessive body weight is occurring in children more often. Aim. The main purpose of this work was to determine the prevalence of overweight and obesity in preschool children from the Rzeszów district, and to determine risk factors for occurrence. Materials and survey method. The study was conducted among 200 preschool children (3 - 6 years of age) from the Rzeszów poviat area. Measurements of height, weight, and determination of BMI were performed and these values are standardized according to the WHO centile grids appropriate for each age group. Survey results. Normal weight was observed in 58% of the respondents, 11% were overweight, and 10.5% were obese, whereas 20.5% of children had undernourishment. Obese children were the largest group among 6-year-olds. Among 4 year old children, abnormal body weight were more frequent in boys. On the other hand, in children aged 5 years, undernourishment or overweight was found more frequently in girls. Conclusions. The study did not confirm a significant relationship between gender, place of residence and socio-economic situation of respondents, and the prevalence of overweight or obesity. The results of this study indicate that the problem of excessive body weight refers to the increasing number of children.
