Abstract

Abstract

Objective To evaluate the quality of published cohort studies of smoking for Chinese population. Methods Cohort studies on the relationship between smoking and disease occurrence/mortality for Chinese population among English and Chinese databases were searched, including PubMed, Embase, Cochrane Library, CNKI, WanFang and VIP, respectively. The Newcastle-Ottawa-Scale (NOS) was used to assess the quality of literature, as well as compared the difference between Chinese and English literature. The change of NOS scores was compared before and after the release of the guide of reporting observational research - "Strengthening the Reporting of Observational Studies in Epidemiology" (STROBE). Results Among 99 records of NOS, 75.76% of the studies were published in English, and the quantity of literature increased year by year. The median and quartile of the total NOS scores were 8.0(7.0, 9.0), respectively. Three items got lower scores, which were representativeness of exposed cohort, follow-up duration, and adequacy of follow-up. The quality of English literature was relatively high, especially in the comparability between two groups and adequacy of follow-up. After STROBE statement released, the total NOS score increased, especially in the comparability. In addition, both Chinese and English literature significantly improved in the assessment of outcomes and representativeness of the exposed cohorts. Conclusions The quantity of publications on the relationship between smoking and diseases for Chinese population is on the rise, especially for English literature. The quality of literature is improving, but some information on cohort studies is not fully reported. Therefore, the quality of publications needs to be strengthened in the future.
