Hypothesis

What are the risk factors for overweight and obesity and how does body mass index change over time in Chinese adults in Shanghai?

Conclusion

The study found a high prevalence of overweight and obesity in Shanghai, with various risk factors identified, and slight changes in BMI over 3.6 years.

Supporting Evidence

  • The prevalence of overweight was found to be 27.5% and obesity 3.7% according to WHO standards.
  • Family history of obesity increased the risk of overweight and obesity by about 1.2-fold.
  • Current male smokers had a lower risk of overweight and obesity compared to nonsmokers.
  • Current male drinkers had a higher risk of overweight and obesity compared to nondrinkers.
  • Medium- and high-educated women had a lower risk of overweight and obesity compared to low-educated women.

Takeaway

This study shows that many adults in Shanghai are overweight or obese, and factors like family history and education can affect this.

Methodology

A population-based longitudinal study analyzed anthropometric and biochemical data from 5364 subjects over a follow-up period of 3.6 years.

Potential Biases

Differences in demographics between subjects followed up and those lost to follow-up could introduce bias.

Limitations

Many subjects were lost to follow-up, primarily due to relocation, which may affect the results.

Participant Demographics

Subjects aged 25–95 years, with a mix of genders and educational backgrounds.
