Abstract
Background: To investigate the association between marriage and the prevalence of overweight and obesity in China.
Methods: We conducted cross-sectional and retrospective cohort analyses using a nationwide sample of 36,310 individuals from the China Health and Nutrition Survey [2004–2015].
Results: The prevalence of overweight and obesity increased from 28.7% to 36.7% and from 8.0% to 14.5% between 2004 and 2015, respectively. The cross-sectional analysis showed that married individuals were at a higher risk of being overweight (OR =2.18; 95% CI, 1.90–2.51) or obese (OR =1.95; 1.57–2.43) than never-married individuals. Divorced/widowed individuals were also at a greater risk of being overweight (OR =1.80; 1.51–2.13) or obese (OR =1.67; 1.28–2.17) than never-married individuals. Retrospective cohort analysis showed that individuals who married during the study were 1.55 (1.13–2.11) times more likely to be overweight than those who remained never-married. Compared to those who remained never-married, individuals who remained married were 1.71 (1.42–2.07) and 1.45 (1.11–1.89) times more likely to be overweight and obese. Individuals who became divorced or widowed were more likely to be overweight (RR =1.59; 1.18–2.15) or obese (RR =1.63; 1.08–2.46) than those who remained never-married. However, the risk of being overweight or obese among those who became divorced or widowed did not differ significantly from the risk among those who remained married.
Conclusions: Marriage contributes to an increased risk of overweight and obesity in China; however, this risk is not significantly reduced by exiting a marriage.
