Dietary Behaviors Related to Obesity of Adolescents in Shanghai

  • Objective To compare the situation of obesity-related behaviours in adolescents in Shanghai between 2004 and 2008, in order to provide a scientific basis for planning future intervention measures and for developing the Risk Behaviors Surveillance System for Youths in Shanghai.

    Methods There were 12 665 and 11 782 students from 19 districts of Shanghai surveyed in 2004 and 2008 respctively. Chi-square and trend chi-square were used to assess the difference of dietary behaviors between different sex and between the two years, also to assess the trend of changes with age.

    Results In 2008, some student's risk behaviors related to obesity such as ‘drink soft beverage everyday’, ‘eat western style fast food weekly’, and ‘take diet pill to lose weight or control weight gain’ were lower than those in 2004; but some other behaviors such as ‘do not have breakfast everyday’, ‘on diet to lose weight or control weight gain’, and ‘fasting to lose weight or control weight gain’ in 2008 were higher than those in 2004. The proportion of ‘take exercise to lose weight or control weight gain’ was 56.8% in 2008, significantly different from the proportion 21.0% in 2004. The proportions were different between sexes, except the ‘do not take breakfast everyday’ in 2008. The proportions were also different in various ages. More students in 2008 than in 2004 took "lose weight or control weight gain by unhealthy methods".

    Conclusion The proportions of behaviors related to obesity in adolescents of Shanghai are still on high le vel, and the feature of distribution is different in sex and age. The rise of unhealthy behaviors to loss weight or control weight gain raises a cue that the public health workers have to pay more attention to it.
