Association of BMI with mortality and health-related quality of life among 4.4 million adults: Evidence from a nationwide, population-based, prospective cohort study.

Aims: The body mass index (BMI), as an easy-to-calculate measure of body fatness, is closely associated with all-cause mortality, but few studies with a large enough scale have examined the relationship between BMI and quality of life. A comprehensive and precise insight into a new range is needed.

Materials And Methods: Based on the ChinaHEART (Health Evaluation And risk Reduction through nationwide Teamwork), a nationwide, population-based cohort study, 4,485,773 participants living in 20,159 communities or villages were passively followed for death records, through a linkage of data with the National Mortality Surveillance System and Vital Registration.

Cardiovascular disease-specific and all-cause mortality across socioeconomic status and lifestyles among patients with established cardiovascular disease in communities of China: data from a national population-based cohort.

Background: Evidence of socioeconomic status (SES)-related health inequality is scarce in patients with cardiovascular diseases (CVDs) who need both lifestyle change and medical care, particularly in developing countries.

Methods: The study employed a nationwide population-based cohort design, covering all 31 provinces of Chinese mainland from September 2014 to March 2021. Participants aged 35-75 years with self-reported CVD diagnoses were included.

Forecasting cardiovascular disease risk and burden in China from 2020 to 2030: a simulation study based on a nationwide cohort.

Background: Cardiovascular disease (CVD) remains a significant public health challenge in China. This study aimed to project the burden of CVD from 2020 to 2030 using a nationwide cohort and to simulate the potential impact of various control measures on morbidity and mortality.

Methods: An agent-based model was employed to simulate annual CVD incidence and mortality from 2021 to 2030.

Influence of Socioeconomic Gender Inequality on Sex Disparities in Prevention and Outcome of Cardiovascular Disease: Data From a Nationwide Population Cohort in China.

Background Knowledge gaps remain in how gender-related socioeconomic inequality affects sex disparities in cardiovascular diseases (CVD) prevention and outcome. Methods and Results Based on a nationwide population cohort, we enrolled 3 737 036 residents aged 35 to 75 years (2014-2021). Age-standardized sex differences and the effect of gender-related socioeconomic inequality (Gender Inequality Index) on sex disparities were explored in 9 CVD prevention indicators.

Cardiovascular disease prevention and mortality across 1 million urban populations in China: data from a nationwide population-based study.

Background: China has been undergoing a rapid urbanisation. There are substantial disparities between old and new urban citizens in access to health care. We aimed to compare cardiovascular disease prevention and death risks among four distinct urban groups.
