宁夏人群期望寿命影响因素定量研究

目的定量研究影响宁夏人群期望寿命的主高危因素，为提高人群期望寿命、制定干预措施提供科学依据。方法使用多阶段抽样，用问卷调查及实验室检测获得影响期望寿命的主危险因素人群暴露率，结合文献采用反事实分析法计算人群归因分值（PAF），并计算去高危因素人群期望寿命增寿年数。结果前5位死因依次是心脑血管疾病、慢性肺疾病、道路交通事故、慢性胃疾病、肝及胆管癌；人群期望寿命75．40岁，期望寿命影响因素前5位是血脂异常（1．41岁）、吸烟（1．32岁）、睡眠不足（0．90岁）、饮酒（0．85岁）、高血压（0．79岁）。结论针对影响人群期望寿命的主行为危险因素进行干预，可以提高人群期望寿命。

Study on the influence of life expectancy of residents in Ningxia

Objective To study the major risk factors for life expectancy of residents in Ningxia, and to provide a scientific ba- sis for developing interventions and improving the population life expectancy. Methods The main risk factors for population exposure rate was obtained by multi - stage sampling, and questionnaire and laboratory testing, combined with literature and counterfactual attri- bution method was used to calculate the population attributable fraction （PAF） and the cause eliminated age of each main disease. Results The top five causes of death were ： cardiovascular and cerebrovascular disease, chronic lung disease, traffic accidents, chronic stomach disease, liver and bile duct cancer. The life expectancy was 75.40 years old. The five top causes of risk factors for life expect- ancy were： Dyslipidemia （ 1.41 ）, smoking （ 1.32 years）, lack of sleep （0.90 years）, and alcohol consumption （0.85 years）, hyper- tension （0.79 years）. Conclusion It is necessary to take the effective measures early preventing the major behavioral risk factors which affected the life expectancy of the population, in order to improve life expectancy.Objective To study the major risk factors for life expectancy of residents in Ningxia, and to provide a scientific ba- sis for developing interventions and improving the population life expectancy.
