Prevalence of Behavioural Risk Factors for Non-communicable Diseases Among Adolescents in Schools in Benin in 2016

Abstract

Introduction: Non-communicable diseases (NCDs) are on the rise in sub-Saharan Africa. The overall objective of this study was to estimate the prevalence of behavioural risk factors for NCDs among adolescents in schools in Benin in 2016. Methods: This was a cross-sectional study conducted in 2016 and involving 3,841 adolescents of 10 to 19 years from 40 secondary schools in Benin. Participants were selected using a 2-level random sampling technique. Data were collected through a self-administered questionnaire and were analysed using Stata software. Associated factors were investigated by a logistic regression. Results: The average age of the participants was 16.54 ± 0.04 and the sex ratio was 1.16. The prevalence of alcohol consumption was 48.3%, and was associated with residence and class. The prevalence of tobacco use was 8%, and was associated with gender, age, type of facility and residence. The prevalence of insufficient physical activity was 56.4%, and was associated with gender. The prevalence of physical inactivity was 12.4%, and was associated with age, class, socioeconomic level of parents and type of facility. The consumption of soft drinks was 34.9%, and was associated with gender and type of establishment. The prevalence of under-consumption of fruit and vegetables was 94.3%. That of consumption of fast food was 38.6%, and was associated with the type of establishment, the class and the person who the adolescent lived with. Conclusion: This work shows the importance of NCDs' Risk Factors in schools. It is now urgent to implement specific interventions in order to reverse the trend.

“…This high prevalence agreed with findings from studies among in-school adolescents in Benin and Burkina Faso. [29,36] This high prevalence of inadequate servings of fruits and vegetables in this study could be attributed to insufficient food at home, the high cost of fruits, the non-availability of fruits, and not liking fruits.
