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

HeartPublished Prospective cohort study

Study context

Population
Adults aged 35–75 years with self-reported CVD in communities of China, September 2014 to March 20215,010 deaths
Participants
104,718 adults
Exposure
Low and medium socioeconomic status (SES) vs high SES
  • High SESn = 27,943reference
  • Medium SESn = 35,802
  • Low SESn = 40,973
Outcome
All-cause and CVD mortality
Follow-up
Mean 48.9±18.9 months
Methodological detailsnationwide population-based, 31 provinces of Chinese mainland
  • Nationwide population-based
  • 31 provinces of Chinese mainland

Main finding

As reported in the abstract

Low SES vs High SESHazard ratio (95% CI)
All-cause death
1.65(1.50–1.80)
CVD death
1.95(1.72–2.20)

Observational data: associations, not effects.

Further findings

OutcomeHR (95% CI)
Low SES with worst lifestyle vs high SES with healthy lifestyleLow SES, worst lifestylevs High SES, healthy lifestyleAll-cause mortality2.72 (2.37–3.12)
Low SES with worst lifestyle vs high SES with healthy lifestyleLow SES, worst lifestylevs High SES, healthy lifestyleCVD mortality3.18 (2.64–3.83)

Joint mediation by lifestyles of excess CVD mortality in low SES

Proportion mediated
19.6% (95% CI 14.8% to 24.2%)
Strongest mediator leisure-time physical activity, then dietary factors
All-cause mortality: similar
  • Interaction P by gender = 0.013
  • Interaction P by urbanity = 0.004
