ObjectivesTo systematically review the prevalence of asthma in adults (>14 years old) in China.MethodsPubMed, Web of Science, CENTRAL, CINAHL, WanFang Data, CBM, CNKI, and VIP databases were electronically searched to collect cross-sectional studies on the prevalence of asthma in Chinese adults from January 2000 to December 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using Stata 15.0 software.ResultsA total of 67 cross-sectional studies, involving 1 381 673 subjects and 19 871 adult asthma patients were included. The results of meta-analysis showed that the prevalence rate of asthma in adults in China was 1.81% (95%CI 1.59% to 2.01%). The subgroup analysis showed that the prevalence rates of asthma in males and females were 1.87% and 1.76%, respectively. The prevalence rates were 2.16% in the northeast region, 1.34% in the central region, 1.63% in the eastern region and 2.23% in the western region. The prevalence rates were 0.73%, 1.53%, and 2.81% in 15-40 years old, 41-60 years old, and >60 years old, respectively. The prevalence rates were 3.07% in illiteracy population, 1.69% in primary school population, 1.46% in junior middle school population, 1.01% in senior high school population and 0.98% in college and above population. The prevalence rates were 2.23%, 2.10%, 1.17%, 1.45%, 1.09%, and 1.41% in agriculture, forestry and animal husbandry personnel, workers, public officials, business and service personnel, military personnel, and other occupations, respectively. The prevalence rates were 1.41% and 1.59% in Han and other ethnic populations, respectively. The prevalence rates were 2.03% in cities and 1.99% in rural areas. And the prevalence rates were 1.22% in 2000 to 2005, 2.07% in 2006 to 2010, 2.25% in 2011 to 2015, and 2.62% in 2016 to 2019.ConclusionsThe prevalence rate of asthma in Chinese adults is higher, which is different due to the influence of age, sex, region, education, and occupation.
Objective To systematically review the rate of delayed consultation among older pulmonary tuberculosis patients in China. Methods Databases including Web of Science, PubMed, The Cochrane Library, CBM, CNKI, VIP, and WanFang Data were electronically searched to collect cross-sectional studies on the incidence of delayed consultation in older patients with tuberculosis in China from January 2000 to August 2021. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed by Stata 15.0 software. Results In total, 76 cross-sectional studies with 461 896 cases involving 321 411 elderly delayed consultation tuberculosis patients were included. The results of meta-analysis showed that the rate of delayed consultation was 55.1% (95%CI 52.0% to 58.1%) in older Chinese adults with tuberculosis. The results of the subgroup analysis showed that the delayed consultation rate of male tuberculosis patients was 57.1% and that in female tuberculosis patients was 60.3%. The delayed consultation rates of patients from the eastern, central, western, and northeastern regions were 54.1%, 58.0%, 56.0%, and 53.3%, respectively, and those of patients aged 60 to 69, 70 to 79, and 80 years or older were 73.1%, 76.8%, and 78.1%, respectively. The delayed consultation rates of tuberculosis patients with illiteracy, primary school education, junior high school education, and above were 50.0%, 56.0%, and 53.4%, respectively. The delayed consultation rates of the patients in the papers published between 2000 and 2005, 2006-2010, 2011-2015, and 2016-2021 were 39.3%, 53.3%, 58.3%, and 54.4%, respectively. Among the different detection methods, the delayed consultation rates of tuberculosis patients due to symptoms or recommendations, referrals, follow-ups, and other detection methods were 72.9%, 69.0%, 73.4%, and 57.2%, respectively. Regarding treatment classification, the delayed consultation rates of initial treatment and the retreatment of pulmonary tuberculosis were 72.3% and 75.2%, respectively. The delayed consultation rates of pulmonary tuberculosis patients with negative and positive etiological examinations were 73.9% and 65.2%, respectively. The delayed consultation rates of farmers and non-farmers with pulmonary tuberculosis were 74.3% and 71.8%, respectively. Conclusion The incidence of delayed consultation among older tuberculosis patients in China remains high and shows a fluctuating upwards trend. Additionally, there are substantial differences in the rates of delayed consultation by gender, age, geographical location, educational level, discovery method, occupation, and so on.
ObjectiveTo systematically review the incidence of social isolation in Chinese elderly population. MethodsCNKI, WanFang Data, VIP, CBM, PubMed, EMbase, Web of Science and CENTRAL databases were electronically searched to collect studies on the incidence of social isolation in China from inception to May 2022. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies, then, meta-analysis was performed by using Stata 15.1 software. ResultsA total of 20 studies involving 86 111 subjects were included. Meta-analysis results showed that the incidence of social isolation among the elderly in China was 27.54% (95%CI 22.15% to 57.74%). The results of subgroup analysis showed that gender, age, educational level, marital status, self-assessment of health, living style, year of publication, and region surveyed were all influential factors of the incidence of social isolation among the elderly in China. ConclusionCurrent evidence shows that the incidence of social isolation among the elderly in China is relatively high. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
