BACKGROUND
The aim of this study was to determine the relationship between parity and obesity in Iranian women.
METHODS
In a cross-sectional study, a total of 6447 urban women aged 40-65 were studied. Parity(number of full-term births), age at menarche, menopausal status, age, height, weight, marital status, education level and occupation were gathered by a checklist. Body Mass Index (BMI) was calculated. Statistical associations between parity and obesity using multiple logistic regression model were examined.
RESULTS
The mean age of the enrolled women was 48.40 ± 6.13 years. The mean BMI was 27.55 ± 4.47 kg/m. Of the total participants enrolled, 3517 (54.55%) had < 3 parities, while 2930 (45.44%) had ≥ 3 parities. The prevalence of obesity (BMI ≥ 30 kg/m) and overweight (30 > BMI ≥ 25) was 27.50 % (95% CI 26.85-28.15) and 43.70% (95% CI 42.98-44.42), respectively. After adjustment for potential confounders, women with ≥ 3 parities were at higher risk of being obese (OR 1.19, 95% CI 1.05-1.35).
CONCLUSION
There was a statistically significant positive association between higher parity and obesity. It is recommended that health policymakers plan appropriate weight loss programs for postpartum.
背景
本研究旨在探讨伊朗女性生育次数与肥胖之间的关系。
方法
采用横断面研究，共纳入 6447 名年龄在 40-65 岁的城市女性。通过检查表收集生育次数（足月产次数）、初潮年龄、绝经状态、年龄、身高、体重、婚姻状况、受教育程度和职业等信息。计算体重指数（BMI）。采用多因素逻辑回归模型分析生育次数与肥胖的相关性。
结果
纳入研究的女性平均年龄为 48.40±6.13 岁，平均 BMI 为 27.55±4.47kg/m。6447 名参与者中，3517 名（54.55%）生育次数<3 次，2930 名（45.44%）生育次数≥3 次。肥胖（BMI≥30kg/m）和超重（30>BMI≥25）的患病率分别为 27.50%（95%CI：26.85-28.15）和 43.70%（95%CI：42.98-44.42）。调整潜在混杂因素后，生育次数≥3 次的女性肥胖风险更高（OR=1.19，95%CI：1.05-1.35）。
结论
生育次数与肥胖之间存在统计学显著的正相关关系。建议卫生政策制定者为产后女性制定适当的减肥计划。
