睡眠时间与2型糖尿病罹患风险之间关系的随访研究

[目的]探讨南京市居民睡眠时间与2型糖尿病(T2DM)发生风险的关系。[方法]社区为基础的人群随访研究,2004年7月对多阶段随机抽取的南京市3个城区和1个郊县社区里常住的35岁以上居民进行基线调查,对无T2DM的人群开展为期3年的随访,于2007年7月进行评估调查。采用多因素Logistic回归方法分析睡眠时间与罹患T2DM风险之间的关联。[结果]剔除基线时T2DM、肿瘤患者,合格的随访样本人群为3727名,3年后共随访到3031名,随访率为81.3%。3年内新确诊的T2DM患者为76人,累计发病率为2.5%;男女发病率无统计学差异(2.5%vs.2.6%)。居民平均每天睡眠时间为7.2h,睡眠时间不足(﹤7h/d)和过长(≥9h/d)的比例分别为24.8%、7.5%。与睡眠时间7h/d相比,睡眠时间不足和过长人群罹患T2DM风险均是其2倍左右;但仅有睡眠不足对T2MD的罹患风险的影响差异有统计学意义(RR=1.83,95%CI:1.12～2.99)。经多因素调整后,睡眠时间﹤7h/d者发生T2DM的风险仍显著高于7～8h者(RR=1.71,95%CI:1.04～2.82);进一步调整基线时BMI和高血压病史,睡眠时间不足人群罹患T2DM风险有所降低,但差异仍有统计学意义(RR=1.68,95%CI:1.02～2.76)。[结论]睡眠时间不足可增加罹患T2DM的风险。睡眠时间可能是T2DM的危险因素之一。
