The health significance of triglyceride-rich lipoproteins, also known as remnant cholesterol, has been increasingly recognized. However, evidence of their associations with cause-specific mortality in the general population was previously insufficient. To explore these associations and their heterogeneities across subgroups, a prospective cohort study was conducted including 3,403,414 community-based participants from ChinaHEART, an ongoing government-funded public health program throughout China, from November 2014 through December 2022. The study assessed mortality risk of all-cause mortality, cardiovascular disease (CVD) mortality (including mortality from ischemic heart diseases (IHD), ischemic stroke (IS), and hemorrhagic stroke (HS), separately), and cancer mortality (including lung cancer, stomach cancer, and liver cancer, separately). During the 4-year follow-up, 23,646 individuals died from CVD (including 8807 from IHD, 3067 from IS, and 5190 from HS), and 20,318 from cancer (including 6208 from lung cancer, 3013 from liver cancer, and 2174 from stomach cancer). Compared with individuals with remnant cholesterol <17.9 mg/dL, multivariable-adjusted mortality hazard ratios (HRs) for individuals with remnant cholesterol ≥27.7 mg/dL were 1.03 (1.00-1.05) for all-cause mortality, 1.17 (1.12-1.21) for CVD (1.19 (1.12-1.27) for IHD mortality, and 1.22 (1.09-1.36) for IS mortality), and 0.90 (0.87-0.94) for all-cancer mortality (0.94 (0.87-1.02) for lung cancer, 0.59 (0.53-0.66) for liver cancer, and 0.73 (0.64-0.83) for stomach cancer). In summary, this study revealed a correlation between increased remnant cholesterol levels and an elevated risk of cardiovascular disease mortality, as well as a reduced risk of mortality for certain types of cancer.

Background:High-density lipoprotein cholesterol (HDL-C) has been inversely associated with cardiovascular disease (CVD) risk, but recent evidence suggests that extremely high levels of HDL-C are paradoxically related to increased CVD incidence and mortality. This study aimed to comprehensively examine the associations of HDL-C with all-cause and cause-specific mortality in a Chinese population.Methods:The China Health Evaluation And risk Reduction through nationwide Teamwork (ChinaHEART) project included 3,397,547 participants aged 35-75 years with a median follow-up of 3.9 years. Baseline HDL-C levels were measured, and mortality data was ascertained from the National Mortality Surveillance System and Vital Registration of Chinese Center for Disease Control and Prevention.Findings:This study found U-shaped associations of HDL-C with all-cause, cardiovascular and cancer mortality. When compared with the groups with the lowest risk, the adjusted hazard ratios (95% CIs) for HDL-C <30 mg/dL was 1.23 (1.17-1.29), 1.33 (1.23-1.45) and 1.18 (1.09-1.28) for all-cause, CVD and cancer mortality, respectively. For HDL-C >90 mg/dL, the corresponding HR (95% CIs) was 1.10 (1.05-1.15), 1.09 (1.01-1.18) and 1.11 (1.03-1.19). Similar U-shaped patterns were also found in associations of HDL-C with ischemic heart disease, ischemic stroke, and liver cancer. About 3.25% of all-cause mortality could be attributed to abnormal levels of HDL-C. The major contributor to mortality was ischemic heart disease (16.06 deaths per 100,000 persons, 95% UI: 10.30-22.67) for HDL-C <40 mg/dL and esophageal cancer (2.29 deaths per 100,000 persons, 95% UI: 0.57-4.77) for HDL-C >70 mg/dL.Interpretation:Both low and high HDL-C were associated with increased mortality risk. We recommended 50-79 mg/dL as the optimal range of HDL-C among Chinese adults. Individuals with dyslipidemia might benefit from proper management of both low and high HDL-C.Funding:The CAMS Innovation Fund for Medical Science (2021-1-I2M-011), the National High Level Hospital Clinical Research Funding (2022-GSP-GG-4), the Ministry of Finance of China and National Health Commission of China, and the 111 Project from the Ministry of Education of China (B16005), the Program for Guangdong Introducing Innovative and Enterpreneurial Teams (2019ZT08Y481), Sanming Project of Medicine in Shenzhen (SZSM201811096), the Young Talent Program of the Academician Fund, Fuwai Hospital Chinese Academy of Medical Sciences, Shenzhen (YS-2022-006) and Guangdong Basic and Applied Basic Research Foundation (2023A1515010076 & 2021A1515220173).

Objective:To examine the joint association of healthy lifestyles and statin use with all-cause and cardiovascular mortality in high-risk individuals, and evaluate the survival benefits by life expectancy.Methods:During 2015-2021, participants aged 35-75 years were recruited by the China Health Evaluation And risk Reduction through nationwide Teamwork. Based on number of healthy lifestyles related to smoking, alcohol drinking, physical activity, and diet, we categorized them into: very healthy (3-4), healthy (2), and unhealthy (0-1). Statin use was determined by self-report taking statin in last two weeks.Results:Among the 265,209 included participants at high risk, 6979 deaths were observed, including 3236 CVD deaths during a median 3.6 years of follow-up. Individuals taking statin and with a very healthy lifestyle had the lowest risk of all-cause (HR: 0.70; 95 %CI: 0.57-0.87) and cardiovascular mortality (0.56; 0.40-0.79), compared with statin non-users with an unhealthy lifestyle. High-risk participants taking statin and with a very healthy lifestyle had the highest years of life gained (5.90 years at 35-year-old [4.14-7.67; P < 0.001]) compared with statin non-users with an unhealthy lifestyle among high-risk people. And their life expectancy was comparable with those without high risk but with a very healthy lifestyle (4.49 vs. 4.68 years).Conclusion:The combination of preventive medication and multiple healthy lifestyles was associated with lower risk of all-cause and cardiovascular mortality and largest survival benefits. Integrated strategy to improve long-term health for high-risk people was urgently needed.

AIM:To determine the associations between the Chinese visceral adiposity index (CVAI) and the risks of all-cause and cause-specific mortality.MATERIALS AND METHODS:A total of 3 916 214 Chinese adults were enrolled in a nationwide population cohort covering all 31 provinces of mainland China. The CVAI was calculated based on age, body mass index, waist circumference, and triglyceride and high-density lipoprotein cholesterol concentrations. We used a Cox proportional hazards regression model to determine the hazard ratios and 95% confidence intervals (CIs) for risk of mortality associated with different CVAI levels.RESULTS:The median follow-up duration was 3.8 years. A total of 86 158 deaths (34 867 cardiovascular disease [CVD] deaths, 29 884 cancer deaths, and 21 407 deaths due to other causes) were identified. In general, after adjusting for potential confounding factors, a U-shaped relationship between CVAI and all-cause mortality was observed by restricted cubic spline (RCS). Compared with participants in CVAI quartile 1, those in CVAI quartile 4 had a 23.0% (95% CI 20.0%-25.0%) lower risk of cancer death, but a 23.0% (95% CI 19.0-27.0) higher risk of CVD death. In subgroup analysis, a J-shaped and inverted U-shaped relationship for all-cause mortality and cancer mortality was observed in the group aged < 60 years.CONCLUSIONS:The CVAI, an accessible indicator reflecting visceral obesity among Chinese adults, has predictive value for all-cause, CVD, and cancer mortality risks. Moreover, the CVAI carries significance in the field of health economics and secondary prevention. In the future, it could be used for early screening purposes.

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. Compared with men, women had seemingly better primary prevention (aspirin usage: relative risk [RR], 1.24 [95% CI, 1.18-1.31] and statin usage: RR, 1.48 [95% CI, 1.39-1.57]); however, women's status became insignificant or even worse when adjusted for metabolic factors. In secondary prevention, the sex disparities in usage of aspirin (RR, 0.65 [95% CI, 0.63-0.68]) and statin (RR, 0.63 [95% CI, 0.61-0.66]) were explicitly larger than disparities in usage of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (RR, 0.88 [95% CI, 0.84-0.91]) or β blockers (RR, 0.67 [95% CI, 0.63-0.71]). Nevertheless, women had better hypertension awareness (RR, 1.09 [95% CI, 1.09-1.10]), similar hypertension control (RR, 1.01 [95% CI, 1.00-1.02]), and lower CVD mortality (hazard ratio, 0.46 [95% CI, 0.45-0.47]). Heterogeneities of sex disparities existed across all subgroups. Significant correlations existed between regional Gender Inequality Index values and sex disparities in usage of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (Spearman correlation coefficient, r=-0.57, P=0.0013), hypertension control (r=-0.62, P=0.0007), and CVD mortality (r=0.45, P=0.014), which remained significant after adjusting for economic factors. Conclusions Notable sex disparities remain in CVD prevention and outcomes, with large subgroup heterogeneities. Gendered socioeconomic factors could reinforce such disparities. A sex-specific perspective factoring in socioeconomic disadvantages could facilitate more targeted prevention policy making.

OBJECTIVES:To assess the different educational inequalities in mortality among generations born between 1940 and 1979 in China, and to investigate the role of socioeconomic, behavioural, and metabolic factors as potential contributors to the reduction of educational inequalities.DESIGN:Nationwide, population based, prospective cohort study.SETTING:The ChinaHEART (China Health Evaluation And risk Reduction through nationwide Teamwork) project in all 31 provinces in the mainland of China.PARTICIPANTS:1 283 774 residents aged 35-75 years, divided into four separate cohorts born in 1940s, 1950s, 1960s, and 1970s.MAIN OUTCOME MEASURES:Relative index of inequality and all cause mortality.RESULTS:During a median follow-up of 3.5 years (interquartile range 2.1-4.7), 22 552 deaths were recorded. Among the four generations, lower education levels were found to be associated with a higher risk of all cause death: Compared with participants with college level education or above, the hazard ratio for people with primary school education and below was 1.4 (95% confidence interval 1.2 to 1.7) in the 1940s cohort, 1.8 (1.5 to 2.1) in the 1950s cohort, 2.0 (1.7 to 2.4) in the 1960s cohort, and 1.8 (1.4 to 2.4) in the 1970s cohort. Educational relative index of inequality in mortality increased from 2.1 (95% confidence interval 1.9 to 2.3) in the 1940s cohort to 2.6 (2.1 to 3.3) in the 1970s cohort. Overall, the mediation proportions were 37.5% (95% confidence interval 32.6% to 42.8%) for socioeconomic factors, 13.9% (12.0% to 16.0%) for behavioural factors, and 4.7% (3.7% to 5.8%) for metabolic factors. Except for socioeconomic measurements, the mediating effects by behavioural and metabolic factors decreased in younger generations.CONCLUSION:Educational inequalities in mortality increased over generations in China. Improving healthy lifestyles and metabolic risk control for less educated people, especially for younger generations, is essential to reduce health inequalities.

BACKGROUND:Since 2010, China has made vast financial investments and policy changes to the primary care system. We aimed to assess how hypertension awareness, treatment, and control might be used to assess quality of primary care systems, which reflect the outcomes of public health services and medical care.METHODS:We used The China Patient-centred Evaluative Assessment of Cardiac Events Million Persons Project, a government-funded public health project that focuses on cardiovascular disease risk in China. We linked primary care institution characteristics that were captured in the survey between 2016 and 2017 to the participant-level data gathered in baseline visits between 2014 and 2021. Participants were included if they had hypertension and lived in the towns or streets that took part in the primary care survey. Participants were excluded if they had missing data for blood pressure measurement, history of hypertension, sex, or age. Primary care institutions were excluded if the catchment area had fewer than 100 participants with hypertension. Hypertension awareness was defined as the proportion of participants with hypertension who self-reported a hypertension diagnosis. Hypertension treatment was defined as the proportion of participants who currently use antihypertensive medications among those who were aware. Hypertension control was defined as the proportion of participants with an average systolic blood pressure less than 140 mm Hg and an average diastolic blood pressure less than 90 mm Hg over two readings among those who were treated during the study. All patients were included in the analysis. This trial was registered at ClinicalTrials.gov, NCT02536456.FINDINGS:Between Sept 15, 2014, and March 16, 2021, we assessed 503 township-level primary care institutions for eligibility. 70 institutions were excluded as they could not be linked with individual data or because their catchment area had fewer than 100 participants with hypertension. We analysed 433 township-level primary care institutions across all 31 provinces of mainland China, including 660 565 individuals with hypertension in their catchment areas. Across townships, age-sex standardised hypertension awareness varied from 8·2% to 81·0%, treatment varied from 2·6% to 96·5%, and control proportions varied from 0% to 62·4%. Hypertension awareness, treatment, and control were significantly associated with the following institutional characteristics: government funding through balance allocation (ie, institutions have their human resources funded by local government, but need to be self-supporting in other aspects; awareness odds ratio 0·88, 95% CI 0·78-0·99; p=0·027), having financial problems that interrupted routine service delivery (awareness 0·81, 0·72-0·92; p=0·0007, control 0·84; 0·75-0·94, p=0·0034), setting performance-based bonus (treatment 1·39, 1·07-1·80; p=0·013), basic salary defined by number of patient visits (control 0·85, 0·76-0·95; p=0·0053), using electronic referrals (treatment 1·41, 1·14-1·73; p=0·0012, control 1·17; 1·03-1·33, p=0·014), implementing family physician contract services (awareness 1·13, 1·00-1·28; p=0·045, control 1·30; 1·15-1·46, p<0·0001), and proportion of physicians who are formally licensed (awareness per 10% increase 1·04, 1·01-1·08; p=0·019, treatment 1·08; 1·02-1·14, p=0·0077; control per 10% increase 1·07, 1·03-1·10; p=0·0006).INTERPRETATION:The role of primary care role in hypertension management might benefit from new strategies that promote best practices in institutional financing, performance appraisal, service delivery, and information technology.FUNDING:Chinese Academy of Medical Sciences Innovation Fund for Medical Science, and the National High Level Hospital Clinical Research Funding.TRANSLATION:For the Chinese translation of the abstract see Supplementary Materials section.

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.METHODS:Urban residents aged 35-75 years living in 96 prefecture-level cities from 31 provinces in mainland China were enrolled in the national population-based cohort China Patient-centered Evaluative Assessment of Cardiac Events Million Persons Project. They were categorised into four groups by their former and current places of residence as follows: old-urban in situ residents (local residents in established urban areas since birth), new-urban in situ residents (local residents in newly urbanised areas established during urbanisation), urban-to-urban migrants (migrants from other urban areas), and rural-to-urban migrants (migrants from rural areas). We excluded participants with missing data for former and current places of residence, medical history, socioeconomic status, or lifestyle information. After adjusting for demographic and socioeconomic characteristics, relative risks (RRs) of cardiovascular disease prevention indicators and hazard ratios (HRs) of cardiovascular mortality and all-cause mortality of the other three population groups were estimated by modified log-Poisson models with robust standard error and Cox proportional hazard models, with old-urban in situ residents as the reference group.FINDINGS:From Sept 1, 2015, to Aug 17, 2020, 1 339 329 residents were enrolled, 270 606 were excluded for missing data in key variables, and 1 068 723 were subsequnetly included in the study. Compared with old-urban in situ residents, new-urban in situ residents were less likely to adhere to a healthy diet (RR 0·72 [95% CI 0·62-0·83]), while no significant results were observed in rural-to-urban migrants; new-urban in situ residents were less likely to use statins as primary prevention (RR 0·60 [0·46-0·79]), angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs; RR 0·78 [0·65-0·93]) and β-blockers (RR 0·68 [0·53-0·88]) as secondary prevention; and rural-to-urban migrants were less likely to use aspirin as a primary (RR 0·67 [0·46-0·96]) and secondary (RR 0·71 [0·54-0·94]) prevention and statins (RR 0·70 [0·51-0·97]) and ACEIs or ARBs (RR 0·68 [0·50-0·93]) as secondary prevention. Furthermore, in people diagnosed with hypertension, new-urban in situ residents were less likely to have their blood pressure controlled (RR 0·79 [95% CI 0·72-0·87]), while no significant results were observed in rural-to-urban migrants. New-urban in situ residents had higher risk of cardiovascular mortality (HR 1·16 [95% CI 1·05-1·29]; p=0·005) than did old-urban in situ residents, after a median follow-up of 2·7 years (IQR 2·0-4·2).INTERPRETATION:New-urban in situ residents and rural-to-urban migrants both showed poorer utilisation of primary and secondary prevention medications than did old-urban in situ residents, while new-urban in situ residents also had lower adherence to healthy lifestyles and higher death risks. Comprehensive measures should be taken to strengthen the primary health-care system in newly urbanised areas, and promote interprovincial medical insurance reimbursement.FUNDING:Chinese Academy of Medical Sciences Innovation Fund for Medical Science and the National High Level Hospital Clinical Research Funding.TRANSLATION:For the Chinese translation of the abstract see Supplementary Materials section.

AIMS:We aimed to demonstrate the distribution of alcohol use disorder (AUD) in China and assess its association with quality of life and mortality.METHODS:We studied 367 120 men aged 35-75 years from 31 provinces in the China Patient-Centered Evaluative Assessment of Cardiac Events (PEACE) Million Persons Project. At baseline, AUD was assessed by alcohol use disorders identification test score, and EQ-5D-3L questionnaire was used to measure the quality of life. Mortality data was collected via National Mortality Surveillance System and Vital Registration. Mixed models were fitted to assess the associations of AUD with quality of life, and Cox proportional hazard models were fitted for the associations with all-cause and cause-specific mortality.RESULTS:We identified 39 163 men with AUD, which accounted for 10.7% of male participants and 25.8% of male drinkers. In the multivariable analysis, male drinkers who were aged 45-54 years, with higher education level, currently smoking, obese, with diagnosed hypertension, and without diagnosed cardiovascular diseases had higher rates of AUD. Male drinkers with AUD were less likely to have optimal QOL compared with those without AUD (OR: 0.63, 95% CI: 0.61-0.65, P < 0.001). Moreover, among male drinkers, AUD was prospectively associated with a 20% higher risk for all-cause mortality and a 30% higher risk for mortality from cancer.CONCLUSIONS:In China one fourth of men who drank alcohol had AUD, which was associated with lower QOL and higher risk of all-cause mortality. National policies or strategies are urgently needed to control alcohol-related harms.
