“…However, inconsistent results are shown in similar studies by Lisowski et al [ 56 ], who reported no sex differences in the prevalence of overweight in children, and by Kantanista et al [ 57 ], indicating BMI may not be a significant factor for boys or girls when planning health-focused PA programs in adolescents aged 14 to 16 years old. Moreover, Nevill et al [ 58 ] suggested that BMI may not properly reflect changes in body fat percentage. Indeed, these authors confirm that there might be differences in BMI by sex even after adjustment of percent body fat.…”

Attaining healthy behaviors is essential at any life stage, particularly childhood, due to the strong link between children’s lifestyle and the subsequent adult state of health. This multidisciplinary study aimed to assess lifestyle behaviors of Austrian pupils of secondary schools I and II, with a specific focus on PA habits and diet types based on a large sample. In total, 8845 children/adolescents participated in the short standardized online survey on relevant health-related aspects nationwide. Valid and complete data was provided by 8799 pupils, including 1.14% of the eligible 771,525; 63% girls, 76% having a normal body weight, 70% attending secondary schools II, and more pupils/students living in rural vs. urban areas (3:1 ratio). Across the total sample, 11.8% were considered overweight/obese with a higher prevalence of overweight/obesity in boys than girls (15.5% vs. 9.6%) and urban vs. rural participants (13.9% vs. 10.8%; p < 0.05). The majority of participants (84.5%) reported a mixed diet, while 7.2% and 8.5% reported a vegan and vegetarian diet, respectively. Vegans reported a lesser alcohol intake (p < 0.05) compared to non-vegan pupils (no difference in dietary subgroups for smoking). Although overall PA and dietary behaviors suggest an appropriate health status among Austrian youth, attention should be focused on policies to increase healthy lifestyle habits at best through a dual approach to health permanently combining regular PA, sports, and exercise with a healthy diet, which would contribute to matching the current recommendations for improving individual and public health.

At the age of 11-15 (the period of younger adolescents), there are significant changes in body composition due to pre-pubertal and pubertal development. In our paper, the differences in indicators of body composition of elementary school students in the context of age and gender were evaluated. Boys and girls from primary schools aged 10-11 years (n=32 and n=38), 12-13 years (n=36 and n=57) and 14-15 years (n= 38 and n=33) were examined. In addition to age, body height (BH), body weight (BW), Quetelet's index (BMI), body fat mass (BFM), body fat mass index (BFMI), skeletal muscle mass (SMM), percentage of body fat (PBF), waist-hip ratio (WHR) and visceral fat (VFA) were monitored. The data were obtained using the InBody 230 device using the multi-frequency bioimpedance method of measuring body composition. The measured data were processed using IBM SPSS Statistics, version 20.0. Since data were not normally distributed (Shapiro-Wilk test), they were processed using non-parametric methods through Kruskal-Wallis Anova (age differences) and multiple comparisons with the Mann-Whitney U test with the application of the Bonferonni adjustment. The most significant differences were only found in the intersex comparison of 14-15-year-old pupils, when in the relative values of fat representation (BFMI and PBF), girls achieved higher mean values, on the contrary, higher values of in the group of boys are visible in the indicators describing active body mass (FFM, FFMI and SMM).
