PG - 188 LID - 10.1186/s13690-023-01197-x [doi] LID - 188 AB - OBJECTIVE: The global epidemic of overweight/obesity in children and adolescents poses a significant public health threat. This longitudinal study aims to investigate the relationship between adolescents' and their parents' dietary knowledge and overweight/obesity among adolescents in China. METHODS: Data were collected from the China Health and Nutrition Survey (CHNS) in 2004, 2006, 2009, 2011 and 2015. Overweight/obesity was defined according to the International Obesity Task Force (IOTF) cut-off for body mass index (BMI). A set of questions were used to assess the dietary knowledge scores of both adolescents and their parents during face-to-face interviews. Mixed effect models were used to analyze the data. RESULTS: A total of 2035 adolescents aged 12-17 years were included in the data analysis. The mean BMI increased from 19.2 in 2004 to 20.5 in 2015, with a significant increase in the prevalence of overweight and obesity from 6.8% and 0.5% in 2004 to 15.1% and 7.8% in 2015, respectively. Adolescents with medium-score dietary knowledge were less likely to be overweight/obese compared to those with low-score dietary knowledge (OR (95% CI): 0.20 (0.05-0.80), P < 0.05). However, there was no association between parental dietary knowledge and adolescents' BMI or overweight/obesity (P > 0.05). Additionally, a significant interaction between adolescents' dietary knowledge score and education in relation to adolescents' BMI (P for interaction < 0.05). CONCLUSION: Adolescents with medium dietary knowledge were less likely to be overweight/obese than those with low knowledge, but no association was found with parental knowledge. Promoting nutritional education and healthy eating habits is vital to prevent overweight/obesity. CI - (c) 2023. BioMed Central Ltd., part of Springer Nature.
