Objectives: To investigate sex differences in sociodemographic and lifestyle correlates of frequent energy drink (ED) consumption in adolescents. Study design: This study was based on data collected among French-speaking Belgian adolescents aged 11e20 years (n ¼ 8137) within the 2018 Health Behaviour in School-aged Children study. Methods: Multiple logistic analyses stratified by sex were performed to estimate the associations between consuming EDs more than once a week, and various sociodemographic and lifestyle characteristics. Results: Overall, 14.0% of boys and 7.6% of girls consumed ED more than once a week. For both genders, the likelihood of consuming ED more than once a week was higher among adolescents consuming soft drinks daily (vs. < daily), alcohol weekly (vs. < weekly), spending at least 5 h/day in front of screens (vs. < 5 h/day), and going to bed later than 11:30 PM (vs. 10:00 PM). Among boys, adolescents reporting at least 1 h of moderate-to-vigorous physical activity (MVPA) daily (vs. < 1 h/day MVPA) were more likely to consume ED more than once a week (adjusted odd ratio (aOR) ¼ 1.49 (95% confidence interval [CI] 1.11e2.01)). Among girls, adolescents from low affluence families (vs. high affluence) (aOR ¼ 2.03 (95% CI 1.19e3.48)) and immigrants (vs. natives) (2nd generation: aOR ¼ 1.75 (95% CI 1.31 e2.32); 1st generation: aOR ¼ 1.90 (95% CI 1.20e3.03)) were more likely to consume ED more than once a week. Conclusions: We identified different patterns of ED consumption in boys and girls. These results suggest that sex-tailored interventions could be relevant to reduce ED consumption in adolescents.
Introduction Early alcohol consumption can irreversible damage the adolescents’ brain and may affect their quality of life. In order to better prevent such a deleterious behaviour, knowing its determinants is needed. So far, only few studies among adolescents aged <15 years exist, of which the majority failed to include gender differences. Therefore, the aim of this study was to investigate whether gender differences in the association between alcohol use and sociodemographic and psychosocial characteristics among 10-14-year olds exist. Methods Data came from the 2018 Health Behaviour in School-Aged Children (HBSC) study conducted in French-speaking schools of Belgium. The sample analysed here comprised 4,364 10-14-year olds from the Walloon Region. Associations of the recent alcohol consumption (at least one glass during the past month) with sociodemographic and psychosocial characteristics were estimated using gender-stratified multivariable logistic regression modelling. Results Prevalence of early alcohol consumption was 14% (boys: 16%; girls: 12%). Migration status and family affluence scale (FAS) were associated with early alcohol consumption only in boys. Second-generation immigrant boys (vs. natives: OR = 0.66 [0.47–0.92]) and boys from “low” FAS families (vs. “high”: OR = 0.56 [0.32–0.98]) or “medium” FAS (vs. “high”: OR = 0.63 [0.43–0.92]) were less likely to have consumed alcohol in the past month. In both genders, alcohol consumption was positively associated with age and inversely associated with school satisfaction and family support. No association was observed with family structure, peer support and life satisfaction in the multivariable models. Conclusion Our findings showed that gender differences may exist in the determinants of alcohol consumption among young adolescents. They will contribute to the development of public health policies and actions for the most vulnerable adolescents, which should take gender differences into account.
Introduction During adolescence, physical activity tends to decline, especially among girls. Adolescent inactivity is due in part to biological factors, among which pubertal development may play a role. Our aim was to study in girls, the relationship of sexual maturation based on menarche with physical activity and sedentary behaviour. Methods Analyses were based on a two-stage random sample of 3,911 10-15-year-old girls included in the 2018 cross-sectional Health Behaviour in School-aged Children survey carried out in French-speaking schools. Menarche, sufficient levels of physical activity (PA) (global PA: at least 60 min. of moderate- to vigorous-intensity PA daily, and vigorous PA: at least 3 times/week), sedentary week time based on all-screen use duration (SWT; categories based on tertiles), and sociodemographic characteristics were self-reported. Multilevel multiple binary (for PA) and multinomial (for SWT) logistic regressions were performed, stratified by age group (≤12.5 years vs. >12.5 years). Results Twenty percent of girls aged ≤ 12.5 years and 85.0% of girls aged > 12.5 years have had their first period. Within the group aged ≤12.5, post-menarcheal girls were more likely to spend long SWT (≥8h/day) than pre-menarcheal girls (vs. short SWT (<4h/day): aRRR= 1.74 [1.27-2.37]; NS for moderate SWT (4-7h/day)). Within those aged >12.5, post-menarcheal girls were less likely to engage in sufficient vigorous PA (aOR=0.76 [0.59-0.98]) than pre-menarcheal girls. Moreover, they were more likely to spend moderate (aRRR=1.70 [1.19-2.42]) and long SWT (aRRR=2.74 [1.94-3.88]) than pre-menarcheal girls of same ages. Additional adjustments for age modified the strength of associations. Conclusions Our results suggest that during adolescence, the physiological changes induced by sexual maturation may contribute to the decline in physical activity (in > 12.5 years), and in the increase in sedentary behaviour in girls. Potential confounding by age will be explored further. Key messages Development of strategies aimed at improving physical activity among adolescent girls should take into account, among other aspects, pubertal development. Specific interventions, targeting pubescent girls, should also be developed to reduce screen time in order to prevent its potential negative consequences.
Background Rising levels of childhood obesity is a worldwide concern, with physical inactivity considered to be amongst the many contributors. Worryingly, physical activity (PA) tends to decline throughout adolescence. Although there is extensive research on the sociodemographic disparities of adolescent PA participation, less evidence is available on the potential involvement of immigration status in such disparities. The aim of this study was to investigate PA levels according to migration status among adolescents aged 12-20 years in Belgium. Methods This study used the data from the cross-sectional 2018 Health Behaviour in School-aged Children (HBSC) survey in French-speaking Belgian schools (Brussels and Wallonia). A two-stage random sample was used to select participants. Data was collected using self-administrated questionnaires. Adolescents aged 12 to 20 were included in the analyses presented here (n = 8635, boys: n = 4179, girls: n = 4456). The association of global PA (GPA) and vigorous PA (VPA) with migration status (natives, 2nd and 1st-generation immigrants) was analysed using multiple binary logistic regression analyses. Interactions with gender were tested. Results The prevalence of adolescents undertaking sufficient GPA (moderate to vigorous PA 60 minutes/day and VPA ≥3 times/week) was higher amongst 1st-generation immigrants (11.7%) compared to 2nd-generation immigrants (7.4%) and natives (8.9%) (p = 0.01). Vigorous PA ≥ 3 times/week was significantly more prevalent amongst natives (52.6%) than 2nd (44.9%) and 1st (48.8%) generation immigrants. After adjusting for sociodemographic variables, compared to natives, 2nd-generation immigrants were less likely to participate in sufficient GPA (aOR= 0.83, 95%CI: 0.69-1.00) and VPA (aOR= 0.77, 95%CI: 0.68-0.87). Conversely, 1st-generation immigrants were more likely to be sufficiently active compared to natives (GPA: aOR= 1.44, 95%CI: 1.03-2.01). An interaction between migration status and gender was found for VPA only (p > 0.001). Compared to natives, 1st-generation immigrant boys were more likely (aOR=1.42, 95%CI: 1.15-1.75) and immigrant girls were less likely to undertake VPA ≥3 times/week (2nd-generation: aOR= 0.66, 95%CI: 0.56-0.78; 1st-generation: aOR=0.72, 95%CI: 0.57-0.90). Conclusions This study shows disparities in PA participation according to migration status and gender, independently of sociodemographic characteristics, for adolescents living in French-speaking Belgium. These findings will enable to inform future public health initiatives promoting PA in adolescents on migration and gender-specific considerations.
