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.
