The rise in noncommunicable diseases and their risk factors in developing countries may have changed or intensified the effect of parity on obesity. We aimed to assess this association in Peruvian women using data from a nationally representative survey.
We used data from Peru's Demographic and Health Survey, 2012. Parity was defined as the number of children ever born to a woman. We defined overweight as having a body mass index (BMI, kg/m) of 25.0 to 29.9 and obesity as a BMI ≥30.0. Generalized linear models were used to evaluate the association between parity and BMI and BMI categories, by area of residence and age, adjusting for confounders.
Data from 16,082 women were analyzed. Mean parity was 2.25 (95% confidence interval [CI], 2.17-2.33) among rural women and 1.40 (95% CI, 1.36-1.43) among urban women. Mean BMI was 26.0 (standard deviation, 4.6). We found evidence of an association between parity and BMI, particularly in younger women; BMI was up to 4 units higher in rural areas and 2 units higher in urban areas. An association between parity and BMI categories was observed in rural areas as a gradient, being highest in younger women.
We found a positive association between parity and overweight/obesity. This relationship was stronger in rural areas and among younger mothers.
发展中国家非传染性疾病及其危险因素的增加可能改变或加剧了生育次数对肥胖的影响。我们旨在利用来自具有全国代表性的调查的秘鲁妇女数据来评估这种关联。
我们使用了来自秘鲁 2012 年人口与健康调查的数据。生育次数定义为女性生育的孩子数量。我们将超重定义为体重指数（BMI，kg/m）为 25.0 至 29.9，肥胖定义为 BMI≥30.0。使用广义线性模型，根据居住区域和年龄调整混杂因素后，评估生育次数与 BMI 和 BMI 分类之间的关联。
分析了 16082 名女性的数据。农村地区女性的平均生育次数为 2.25（95%置信区间[CI]，2.17-2.33），城市地区为 1.40（95% CI，1.36-1.43）。平均 BMI 为 26.0（标准差 4.6）。我们发现生育次数与 BMI 之间存在关联，尤其是在年轻女性中；农村地区的 BMI 高出 4 个单位，城市地区高出 2 个单位。在农村地区，生育次数与 BMI 分类之间存在关联，呈梯度分布，在年轻女性中最高。
我们发现生育次数与超重/肥胖之间存在正相关。这种关系在农村地区和年轻母亲中更强。
