Predictive value of women's weight trajectories in determining familial cardiovascular disorders: a family-based...

Considering the dynamic nature of body mass index (BMI) and its importance in determining cardiovascular risks, this study aimed to investigate the life-course trajectory pattern of women's BMI and its association with cardiovascular risk factors. A total of 1356 couples with 2976 children were recruited and followed up for an average period of 20 years. Latent growth curve modeling was applied to determine women's BMI trajectories; logistic regression was used to investigate the associations between trajectory patterns and cardiovascular risk factors, including hypertension (HTN), dyslipidemia, diabetes mellitus (DM), and obesity. Women were classified into three trajectories, including normal, stage 1 obesity, and stage 2 obesity. Compared to women's in the normal trajectory group, those in obesity trajectories had higher odds ratios for HTN, DM, and dyslipidemia. Men with obese spouses showed a higher rate of HTN 1.54 (95% CI 1.05-2.25) and DM 1.55; (95% CI 1.00-2.44). The odds of men's obesity were higher in obese spouses (OR 1.70; 95% CI 1.10-2.62). Offspring of stage 2 obese (OR 2.39; 95% CI 1.67-3.44) and stage 1 obese (OR 4.81; 95% CI 3.16-7.34) mothers were more likely to be obese. Our findings emphasized paying more attention to women with excessive weight to promote familial cardiovascular health in the communities.
