【摘要】 目的：描述成都市居民饮茶习惯，探讨居民饮茶的影响因素；开发SF-8中文量表，测试其性能，并利用其测量成都市居民健康相关生命质量；采用结构方程模型分析饮茶等因素对健康相关生命质量的影响作用。方法：采取多层抽样方法，在成都市成华区和青羊区共抽取1517名调查对象进行问卷调查。由临床或预防医学专业硕士研究生担任调查员，使用统一的调查问卷，进行入户和户外设点调查相结合的方式，同被调查者进行面对面的访谈。问卷主要内容包括一般情况、饮茶信息、健康信息和健康生命质量测量量表(SF-8)。结果：(1)77.3％的被调查对象现在有饮茶习惯，是否饮茶在不同性别、年龄、教育程度、职业分布不平衡。饮茶者中有51.5％的人饮用绿茶，45.5％饮用花茶。饮茶种类与性别、年龄、教育程度、职业、个人收入及家庭收入等因素相关。饮茶者每周饮茶次数平均为10.44±4.77次／周，每周饮茶剂量平均为59.00±50.47g／周。(2)通过对SF-8中文量表的性能测试，其总体克朗巴赫α系数为0.749，以SF-36为校标计算的校标效度为0.563。采用因子分析评价量表结构效度，共提取出3个公因子，即躯体健康、心理健康和整体健康三个方面。这都反映了SF-8中文量表具有较好的信度与效度。SF-8量表对成都市居民健康相关生命质量测量总分平均为88.71。(3)通过4个理论上可接受的结构方程模型之间竞争，模型4更接近饱满模型，其X~2值为348.820，自由度为66，NFI为0.995，RMSEA为0.053，所以最终接受模型4。根据模型4，饮茶因素为心理健康的保护因素，但与躯体健康的关系无统计学意义。此外，心理健康还同是否运动有关，躯体健康同年龄、性别、是否运动以及是否患有慢性病有关。结论：成都市居民中饮茶比例较高，以绿茶和花茶为主。SF-8中文量表具有较好的信度和效度，可在以后研究中推广应用。在健康相关生命质量影响因素分析中采用结构方程模型的分析方法是可行的。饮茶因素、年龄、性别、是否运动以及是否患有慢性病与健康相关生命质量相关。更多还原

【Abstract】 A study on tea consumption and health-related quality of life among residents in Chengdu City[Objective] The study was designed to describe the tea dinking habits among residents in Chengdu, and to learn about the influential factors of drinking tea.; to development and evaluation of Chinese version of Short Form 18 (SF-8), and measure health-related quality of life (HRQOL) with SF-8 for residents in Chengdu; to explore the relationship between tea consumption and health-related quality of life with structural equation model(SEM).[Methods] 1517 citizen from Chenghua and Qingyang district in Chengdu were selected by stratified sampling. The investigators, postgraduate students of public health and medicine, interviewed the residents with standard questionnaire which included basic information, tea drinking information, health information and SF-8.[Results] (1) There were 77.3% residents drunk tea, which was influenced by sex, age, education and occupation. There were 51.5% drunk green tea in tea drinker, and 45.5% drunk jasmine tea. The type of tea associated with sex, age, education, occupation, single income and family income. Tea drinkers drunk 10.44±4.77 times per day, consume tea 59.00±50.47g per week.(2) Cronbach’a coefficient of SF-8 was 0.749; correlation coefficient between SF-8 and SF-36 was 0.559; 3 factors mental health, physical health and integrated health, were sorted, which accounted for 71.741% of the scale’ s total variances. All these revealed the good reliability and validity of SF-8. And the average score of Chengdu residents’ HRQOL was 88.71.(3) With competition between 4 acceptable SEMs, model 4 was the best one, with x~2 348.820, Df 66, NFI 0.995, RMSEA 0.053. According to model 4, tea drinking is protecting factor to mental health. But the relationship between tea drinking and physical health has no significance. Besides, mental health relates to sports, and physical health relates to age, sex, sports and chronic disease.[Conclusion] The proportion of tea drinkers in Chengdu residents is high, who mainly drink green tea and jasmine tea. SF-8 has good reliability and validity; it can be used widely in the future study. It is feasible to use SEM to analyze the influential factor of HRQOL. Tea drinking, age, sex, sports, chronic disease relate to HRQOL.更多还原
