目的：在转型后国家，肥胖对妇女的影响不成比例。纵向研究可以发现需要采取行动的高危人群。我们调查了智利育龄妇女BMI变化的幅度和速度，并评估这些趋势是否在特定群体中有所不同。设计：纵向研究。我们分别在2007年（基线）和2010年（随访）测量了体重和身高；我们估计了3年内BMI（体重/身高(2)）的变化，并评估了其与年龄、受教育年限和性别的关系，这些数据是在基线和随访时使用问卷收集的。背景：以人群为基础的智利中低收入妇女队列。受试者：参加生长与肥胖队列研究（GOCS）的761名育龄妇女（平均32.0 （SD 7.0）岁），均为儿童的母亲。结果：基线时，61%的女性BMI = 25.0 kg/m(2)。3年后，女性平均体重增加2.6公斤，肥胖（BMI指数= 30.0 kg/m(2)）增加了23%（12%的新肥胖病例）。营养状况正常的女性BMI高于肥胖女性（1.4 vs . 0.6 kg/m, P < 0.001）。胎次增加与BMI变化呈正相关，与年龄、营养状况和教育程度无关（P < 0.05）。在控制其他因素后，年龄和受教育程度与BMI变化无相关性（P < 0.05）。结论：在智利这个转型后的国家，我们观察到育龄妇女肥胖率的惊人增长。我们的结果表明，在这一人群中，需要针对所有妇女采取行动，而不管她们的营养状况如何。这些政策的一个关键组成部分应该是避免怀孕期间体重过度增加。
Objective: In post-transitional countries, obesity disproportionally affects women. Longitudinal studies can detect high-risk groups in whom to target actions. We investigated the magnitude and velocity of BMI changes in Chilean women of reproductive age and evaluated whether these trends vary in specific groups.Design: Longitudinal study. We measured weight and height in 2007 (baseline) and again in 2010 (follow-up); we estimated change in BMI (weight/height(2)) within the 3-year period and assessed its relationship with age, years of education and parity, collected at baseline and follow-up using a questionnaire.Setting: Population-based cohort of low- to middle-income Chilean women.Subjects: Seven hundred and sixty-one women of reproductive age (mean 32.0 (SD 7.0) years), mothers of children who participate in the Growth and Obesity Cohort Study (GOCS).Results: At baseline, 61 % of women had BMI >= 25.0 kg/m(2). After 3 years, women gained on average 2.6 kg and obesity (BMI >= 30.0 kg/m(2)) increased by 23 % (12 % new obesity cases). Women with normal nutritional status gained more BMI than obese women (1.4 v. 0.6 kg/m(2), P < 0.001). An increase in parity was positively associated with BMI change, independently of age, nutritional status and education (P < 0.05). Age and education were not associated with BMI change after controlling for other factors (P > 0.05).Conclusions: In Chile, a post-transitional country, we observed an alarming increase in obesity among women of reproductive age. Our results indicate that in this population actions need to be targeted at all women irrespective of their nutritional status. A key component of these policies should be avoiding excessive weight gain during pregnancy.
