 目的  探究上海市职业人群工作时间、心理健康状况与失眠的关系。方法  采用方便抽样的方法,在上海市抽取24家用人单位,再从用人单位中抽取2 000名职工进行自编问卷调查。采用WHO-5身心健康指标检测心理健康状况、Nakata失眠状况问卷检测失眠状况。同时调查人口学特征、每周平均工作时间、职业紧张情况、行为危险因素及慢性病患病情况等。结果  将心理健康状况与工作时间的交互作用纳入分析模型发现,当心理健康状况较差,合并平均每周工作>40 h患有失眠的危险性最大,相对心理状况较好并且每周工作≤40 h 的OR为2.80 (95%CI:1.98~3.97),而当心理健康状况较好,平均每周工作时间>40 h表现为与失眠无统计学意义,相对心理健康状况较好并且每周工作≤40 h的OR值为0.77 (95%CI:0.56~1.08)。结论  工作时间与睡眠的关系可能受心理健康状况的影响,在心理健康状况不良的情况下,超时工作成为失眠的危险因素,在心理健康状况良好的情况下,超时工作与失眠无统计学关系。
