BACKGROUND & AIMS: Non-Alcoholic Fatty Liver Disease (NAFLD) is a global public health risk. The occurrence of adolescent NAFLD coincides with high rates of overweight and obesity, with an unhealthy lifestyle also playing a role. Data on prevalence and factors contributing to NAFLD among Asian adolescents is lacking as most studies focus on adults. This systematic review aims to determine the prevalence and factors contributing to NAFLD among adolescents.
METHODS: A systematic search was conducted using five (Goh et al., 2013) [5] databases: Cochrane, PubMed, Scopus, Science Direct, EBSCO and grey literature. Two reviewers independently screened studies using predefined inclusion and exclusion criteria and performed data extraction. Assessment of methodological quality was completed using the Newcastle-Ottawa checklist.
RESULTS: The quality of most studies were of high quality, with the majority reporting no association between lifestyle factors and NAFLD. A total of 6 studies were included in this systematic review. The prevalence of NAFLD among adolescents varied between 8.0% (Fraser et al., 2007) in a study on 5586 adolescents aged 12-19 and 16.0% (Chen et al., 2009) in another survey of 1724 adolescents aged 12-13 years old. Snacking habits and lack of physical activity had potential associations with adolescent NAFLD. Current evidence shows that lifestyle factor (Western dietary pattern) is associated with a higher risk of developing NAFLD among adolescents.
CONCLUSIONS: Lifestyle factors, including snacking habits and lack of physical activity, were associated with a higher risk of developing NAFLD among adolescents from high-income countries. The difference in the prevalence of NAFLD between countries with different incomes requires further investigation.
