Ethnic differences in bmi among Dutch adolescents
What is the role of screen viewing, active commuting to school, and consumption of soft drinks and high-caloric snacks?
Samenvatting
Background: The threats posed by the rising prevalence of overweight and obesity on public health have been widely acknowledged. Several population groups, which deserve special attention because of their higher prevalence rates, have been identified. These include adolescents and ethnic sub-groups.
The aim of the present study was twofold:
- to assess ethnic differences in body mass index (BMI) and in behaviours that are related to both energy intake and energy expenditure, and
- to examine whether these behaviours explain the relationship between ethnicity and BMI.
Methods: We conducted a cross-sectional data analysis among 957 Dutch adolescents (mean age = 12.7 years). Body height and weight were measured using a standardized protocol. Adolescents completed a questionnaire on screen-viewing behaviour, physical activity, consumption of sugarcontaining beverages, and consumption of high-caloric snacks.
Conclusion: Behaviours related to both energy expenditure and energy intake may contribute to the ethnic differences in BMI in adolescents and should be considered when tailoring overweight prevention programs to ethnic subpopulations.
