Abstract: Background　In recent years，the incidence of chronic diseases in China has been increasing rapidly，causing a heavy burden of disease.As a controllable factor in the risk factors of chronic diseases，behavioral lifestyle is very important for prevention and control of chronic diseases.Objective　To explore the types of common chronic diseases and the association between common chronic diseases and the residents' lifestyle in Shanxi Province，so as to provide basis for intervention of chronic diseases.Methods　The multi-stage random sampling method was used to survey the residents aged 35 years and over in Shanxi Province.The contents include basic demographic characteristics, behavior and lifestyle, and chronic diseases.Latent class analysis was applied to classify the individuals into different groups.Further studies were conducted to compare the prevalence of chronic diseases among different lifestyle groups.Results　A total of 3 800 questionnaires were distributed and 3 496 valid questionnaires were recovered，with an effective recovery rate of 92.00%.The prevalence of chronic diseases in Shanxi Province was 39.99%（1 398/3 496），among which hypertension 〔20.68%（723/3 496）〕，diabetes 〔8.67%（303/3 496）〕，rheumatoid arthritis 〔6.61%（231/3 496）〕 and hyperlipidemia 〔5.84%（204/3 496）〕 were identified as common chronic diseases according to the rank of disease prevalence.Four latent classes were yielded：behavioral health group〔59.98%（2 097/3 496）〕，smoking and drinking group〔19.99%（699/3 496）〕，unhealthy diet group〔12.01%（420/3 496）〕 and unhealthy lifestyle group〔8.01%（81/3 496）〕.The prevalence of hypertension，diabetes and hyperlipidemia among the four groups were different （P<0.05）. There was no significant difference in the prevalence of rheumatoid arthritis among the four groups （P>0.05）. Conclusion　There was a clear classification of behavioral lifestyles among residents in Shanxi Province.Distribution of people with hypertension，diabetes mellitus and hyperlipidemia in different latent categories was significantly different.Different intervention strategies should be advocated for people in different categories.

摘要： 背景　近年来，我国慢性病发病呈快速上升趋势，造成了沉重的疾病负担，行为生活方式作为慢性病危险因素中的可控因素，对于慢性病的防控至关重要。目的　初步确定山西省常见慢性病的种类，探讨常见慢性病与居民日常行为生活方式之间的关联性，为慢性病的干预提供依据。方法　于2017年6—9月通过多阶段随机抽样方法对山西省35岁及以上居民进行问卷调查，内容包括基本人口学特征、行为生活方式、慢性病患病情况。采用潜在类别分析方法对研究对象的生活行为方式进行聚类，比较不同生活行为方式居民的慢性病患病率。结果　共发放问卷3 800份，回收有效问卷3 496份，有效回收率为92.00%。山西省居民慢性病患病率为39.99%（1 398/3 496），其中按照疾病别患病率顺位将高血压〔20.68%（723/3 496）〕、糖尿病〔8.67%（303/3 496）〕、类风湿关节炎〔6.61%（231/3 496）〕、高脂血症〔5.84%（204/3 496）〕确定为常见慢性病。潜在类别分析将研究对象分为4类：行为生活方式基本健康组〔59.98%（2 097/3 496）〕，吸烟、饮酒组〔19.99%（699/3 496）〕，饮食不健康组〔12.01%（420/3 496）〕及行为生活方式不健康组〔8.01%（81/3 496）〕。4组居民高血压、糖尿病、高脂血症患病率不同（P<0.05）；4组居民类风湿关节炎患病率比较，差异无统计学意义（P>0.05）。结论　山西省居民的行为生活方式有明显的分类特征，不同潜在类别中高血压、糖尿病、高脂血症人群分布存在明显的差异，应针对不同类别人群的行为生活方式进行差异性干预。
