Data of relevant epidemiological studies were collected by searching articles in PubMed, Web of Science, and Embase till 29 June 2017. Random-effects models were employed to combine study-specific risks.

The joint effects of major lifestyle factors on colorectal cancer risk among Chinese men: A prospective cohort study.

Previous studies have suggested individual healthy lifestyle factors are related to lower risk of colorectal cancer. Their joint effects, however, have rarely been investigated. We aimed to assess the combined lifestyle impact on colorectal cancer risk and to estimate the population attributable risks of these lifestyle factors.

Combined Impact of Known Lifestyle Factors on Total and Cause-Specific Mortality among Chinese Men: A Prospective Cohort Study.

Impact of combined lifestyles on risk of mortality needs to be explored quantitatively. We aimed to evaluate the associations of combined lifestyle factors with total and cause-specific mortality in Chinese men. We used data from the Shanghai Men's Health Study (2002-2013), an on-going population-based prospective cohort study of men (aged 40 to 74 years).

Dietary antioxidant vitamins intake and mortality: A report from two cohort studies of Chinese adults in Shanghai.

Background: Few studies have evaluated dietary antioxidant vitamins intake in relation to risk of mortality in Asia.

Methods: We examined the associations between total carotene, vitamin C, and vitamin E from diet and risk of mortality from all causes, cancer, and cardiovascular disease in 134,358 participants (59,739 men and 74,619 women) from the Shanghai Men's Health Study and Shanghai Women's Health Study, two prospective cohort studies of middle-aged and elderly Chinese adults in urban Shanghai. Participants were followed up for a median period of 8.

Green tea consumption and cause-specific mortality: Results from two prospective cohort studies in China.

Background: Green tea is one of the most widely consumed beverages in Asia. While a possible protective role of green tea against various chronic diseases has been suggested in experimental studies, evidence from human studies remains controversial.

Methods: We conducted this study using data from Shanghai Men's Health Study (SMHS) and Shanghai Women's Health Study (SWHS), two population-based prospective cohorts of middle-aged and elderly Chinese adults in urban Shanghai, China.

Dietary, circulating beta-carotene and risk of all-cause mortality: a meta-analysis from prospective studies.

Observational studies evaluating the relation between dietary or circulating level of beta-carotene and risk of total mortality yielded inconsistent results. We conducted a comprehensive search on publications of PubMed and EMBASE up to 31 March 2016. Random effect models were used to combine the results.

Dietary selenium intake and mortality in two population-based cohort studies of 133 957 Chinese men and women.

Objective: To investigate the potential influence of dietary Se intake on mortality among Chinese populations.

Design: We prospectively evaluated all-cause, CVD and cancer mortality risks associated with dietary Se intake in participants of the Shanghai Women's Health Study (SWHS) and the Shanghai Men's Health study (SMHS). Dietary Se intake was assessed by validated FFQ during in-person interviews.

Association Between Television Viewing Time and All-Cause Mortality: A Meta-Analysis of Cohort Studies.

Findings on the association between television (TV) viewing and all-cause mortality in epidemiologic studies have been inconsistent. Therefore, we conducted a meta-analysis of data from prospective cohort studies to quantify this association. Relevant articles were identified by searching MEDLINE (PubMed; National Library of Medicine, Bethesda, Maryland) and EMBASE (Elsevier B.
