More than half of women in the central south of China have central obesity, spend more than 4 hours of sedentary time per day, or do not consume the recommended amount of fruits and vegetables. Healthier lifestyle interventions are needed to prevent central obesity, including reducing sedentary time to less than 4 hours per day for peri- and post-menopausal women, and increasing fruit and vegetable intake to five servings per day for pre-menopausal women.
(1) Background: The prevalence of central obesity is growing rapidly among women, and the prevalence differs by menopausal status. Longer sedentary time and less fruit/vegetable (F/V) intake increased the risk of central obesity. Among women of different menopausal statuses, controversy surrounds the association between sedentary time or F/V intake and central obesity. This study aimed to explore whether the independent and joint associations between sedentary time or F/V intake and menopausal status are correlated with central obesity, respectively. (2) Methods: This cross-sectional study was conducted in Hunan, China. Self-reported questionnaires were used to gather information on demographic characteristics, menopausal status, sedentary time, and F/V intake. Waist circumference was measured at the study site. Binary logistic regression and multiple interaction models were used to explore the independent and joint associations of menopausal status and the above two lifestyle variables with central obesity. (3) Results: A total of 387 women with a mean age of 47.7 +/- 6.6 years old participated in the study. The prevalence of central obesity was 52.8%. Peri- and post-menopause statuses and not taking five servings of F/V per day were risk factors of central obesity (p < 0.05), whereas no significant association was found between sedentary time and central obesity (p > 0.05). Among peri-menopausal (mutual odds ratio (OR): 2.466, 95% confidence interval [CI]: 0.984-6.182; p < 0.05) and post-menopausal women (mutual OR: 2.274, 95% CI: 1.046-4.943; p < 0.05), more than 4 h of sedentary time per day was associated with a high risk of central obesity. Among pre-menopausal women, the consumption of five servings of F/V per day was associated with a low risk of central obesity (mutual OR: 0.444, 95%CI: 0.236-0.837, p < 0.05). (4) Conclusions: More than half of women in the central south of China presented with central obesity, spent >4 h of sedentary time per day, or did not engage in recommended F/V intake. Healthier lifestyle intervention is warranted to prevent central obesity development, including reducing the sedentary time to <4 h per day for peri- and post-menopausal women, while increasing taking five servings of F/V per day for pre-menopausal women.
