Objective: To examine the odds of overweight and related correlates in Chinese adolescents. Method: Cross-sectional study in 9023 adolescents. Results: Chinese youth were more likely to be overweight if they spent more time being sedentary; slept <7 hours/night; were male; were younger; participated more in vigorous physical activity; and had higher levels of parental education, a higher frequency of veg-etable intake, and a lower frequency of sweet/fast food intake. Conclusions: Overweight-related correlates seem to play different roles in the Chinese culture than in Western cultures. This may be due to culture-specific perceptions and changes in lifestyle accompanying socioeconomic transitions.
