Abstract

Objective: To describe the prevalence of preserved ratio impaired spirometry (PRISm) in participants from the China Kadoorie Biobank (CKB) and explore the influencing factors. Methods: The CKB project conducted the baseline survey, the first and the second resurvey in 2004-2008, 2008, and 2013-2014, respectively. Based on the lung function tests, the participants were categorized into three groups: regular, PRISm, and airflow obstruction. The prevalence of PRISm was reported by gender, age, and region at the baseline survey. The secular trend in the prevalence of PRISm was described during the three surveys. Finally, we used the multiple logistic regression model to examine the factors related to PRISm in the baseline survey. Results: After standardization for gender, age, and region according to the sixth national census data in 2010, the overall prevalence of PRISm and airflow obstruction among the 434 760 participants at baseline was 24.8% and 6.1%, respectively. The prevalence of PRISm was higher in rural (25.4%) than that in urban areas (24.3%). Of the 10 study regions, Gansu had the highest prevalence of PRISm (56.0%), while Henan had the lowest (15.4%). After standardization for gender, age, and region according to the baseline population, the prevalence of PRISm decreased from 24.9% at baseline to 15.7% in the second resurvey, and the prevalence of airflow obstruction increased from 5.9% to 21.4%. Unmarried status, current smoking, using solid fuels for cooking, low body weight, being overweight, obesity, and central obesity were associated with an increased risk of PRISm. In contrast, higher education attainments, increased household income, and maintaining a specific degree of physical activity were associated with a reduced risk of PRISm. Conclusions: The prevalence of PRISm was high in adults aged 40 years and above in China, and it varied by sociodemographic and lifestyle factors.

[中国10个地区40岁及以上成人保留比值肺功能受损患病率及影响因素]。

目的：了解中国嘉道里生物样本库（CKB）参与者中保留比肺功能受损（PRISm）的流行情况，并探讨其影响因素。方法：CKB项目分别于2004-2008年、2008年和2013-2014年进行基线调查、第一次调查和第二次调查。根据肺功能测试，将参与者分为三组：常规组、PRISm组和气流阻塞组。PRISm的流行程度在基线调查中按性别、年龄和地区报告。在三次调查中描述了PRISm流行的长期趋势。最后，我们使用多元逻辑回归模型来检验基线调查中与PRISm相关的因素。结果：根据2010年第六次全国人口普查数据，对性别、年龄和地区进行标准化后，434760名参与者基线时PRISm和气流阻塞的总体患病率分别为24.8%和6.1%。PRISm在农村的患病率（25.4%）高于城市（24.3%）。10个研究区中，甘肃PRISm患病率最高（56.0%），河南最低（15.4%）。根据基线人群进行性别、年龄和地区标准化后，PRISm的患病率从基线时的24.9%下降到第二次调查时的15.7%，气流阻塞的患病率从5.9%上升到21.4%。未婚、吸烟、使用固体燃料做饭、体重过轻、超重、肥胖和中心性肥胖与PRISm风险增加相关。相比之下，较高的教育程度、增加的家庭收入和保持一定程度的身体活动与PRISm的风险降低有关。结论：PRISm在中国40岁及以上成年人中患病率较高，且受社会人口和生活方式因素的影响。
