摘要:
目的 分析我国孕妇妊娠期糖尿病(gestational diabetes mellitus, GDM)的发病率及不健康生活方式在孕妇人群中的分布, 并探究二者之间的关联性, 以期为降低孕期合并症提供理论依据。 方法 收集2018年12月31日前分娩的中国孕产妇队列中纳入的孕妇, 通过调查问卷收集孕妇孕早期的体力活动、久坐、烟草暴露、酒精摄入、饮食及睡眠水平共6项生活方式指标, 并收集孕妇GDM发病情况。采用二分类Logistic回归分析模型分析不健康生活方式与GDM之间的关联性。 结果 在3 162例孕妇中有372例孕妇被诊断为GDM。单因素分析结果显示缺乏体力活动(RR=1.015, 95% CI=1.005~1.279, P=0.046)和低睡眠水平(RR=1.019, 95% CI=1.004~1.196, P=0.047)是GDM的独立危险因素。与无不健康行为的孕妇相比, 6种全部有表现者有更高的GDM发病风险(RR=1.530, 95% CI=1.263~8.880, P=0.036)。 结论 我国孕妇的GDM发病率为11.76%, 缺乏体力活动和低睡眠水平会增加GDM的发病风险, 有多种不健康生活方式会增大GDM风险。适量运动、戒烟戒酒、合理饮食等多种健康生活方式是预防GDM合理有效的方式。 Abstract:Objective To analyze the incidence of gestational diabetes mellitus(GDM) among Chinese pregnant women and the distributions of unhealthy lifestyles. Exploring the association between these behaviors and GDM to provide some suggestions to GDM prevention. Methods Women who were enrolled by the Chinese Pregnant Women Cohort Study and delivered before the 31 st December, 2018 were enrolled by this study. The characters of physical activity, sedentary lifestyle, tobacco exposure, alcohol consumption, unhealthy diet and low sleep level were assessed by questionnaire and also the pregnancy complications. Binary Logistic regression model was adopted to analyzed the relationship between the dependent and independent variables. Results A total of 3 162 women were enrolled in this study and 372 of them were diagnosed GDM. Single variable analysis showed that lack of leisure time physical activity(RR=1.015, 95% CI=1.005-1.279, P=0.046) and low sleep quality(RR=1.019, 95% CI: 1.004-1.196, P=0.047) were two risk factors of GDM. Compared with women who showed none of these unhealthy lifestyle, those who showed all six unhealthy behaviors had higher risk of GDM(RR=1.530, 95% CI: 1.263-8.880, P=0.036). Conclusions The incidence of GDM among Chinese women was 11.76%. Lack of physical activity and poor sleep quality could increase the risk of GDM and the cluster of unhealthy lifestyles is associated with higher GDM risk. Adequate physical activity, no smoking and drinking, balanced diet and other healthy behaviors are important to GDM prevention. -
