Does educational level and marital status affect BMI and obesity risk in Chinese twins?
Odds Ratio: 2.35 (95% CI 1.8–3.08)
p-value: p=<0.001
Marital status and BMI were associated independent of familial factors for both sexes, while common genetic and shared environmental factors contributed to education-associated disparities in BMI in females.
Liao et al. (2018) conducted a cross-sectional in Obesity (n=20,896). Marital status (married vs unmarried) and educational level vs. Unmarried / Primary education was evaluated on Obesity (BMI ≥28 kg/m2) (OR 2.35, 95% CI 1.80-3.08, p=<0.001). Being married was associated with a significantly higher risk of obesity in both men (OR 2.35) and women (OR 2.16), while higher education increased obesity risk in men but decreased it in women.
