Аннотация
OBJECTIVES: Health check-ups constitute an essential part of China's primary health care policy and a key measure for health screening and risk assessment for elderly people with hypertension and chronic diseases. The role of health check-ups in reducing the incidence of cardiovascular and all-cause mortality remains controversial. This study aimed to investigate the relationship between health check-ups and cardiovascular and all-cause mortality in elderly individuals with hypertension.
STUDY DESIGN: Retrospective cohort study.
METHODS: This study included 625,279 elderly participants with hypertension. Associations of regular and irregular health check-ups with cardiovascular disease related (CVD-related) mortality, all-cause mortality and non-CVD-related mortality were tested via the inverse probability of treatment weighting (IPTW) matching and Cox proportional hazard models. Adjusted hazard ratios (HRs) and 95 % confidence intervals (CIs) were estimated for mortality.
RESULTS: A total of 625,279 participants completed health assessments. During a median follow-up of 5.43 years, 45,927 CVD-related deaths and 25,519 non-CVD-related deaths were recorded. After IPTW, regular health check-ups were significantly associated with reduced CVD-related mortality and all-cause mortality (HR: 0.442, 95 % CI: 0.434-0.450; and HR: 0.441, 95 % CI: 0.435-0.448, respectively). An even stronger association between regular health check-ups and reduced CVD-related mortality was observed in participants with diabetes (HR: 0.40, 95 % CI: 0.39-0.42, P for interaction <0.001), dyslipidaemia (HR: 0.43, 95 % CI: 0.42-0.44, P for interaction <0.001) and a high risk or very high risk of hypertension (HR: 0.41, 95 % CI: 0.40-0.42, P for interaction <0.001).
CONCLUSIONS: Regular health check-ups may be associated with reductions in CVD mortality and all-cause mortality in the elderly population with hypertension, especially in individuals with diabetes, dyslipidaemia and a high risk or very high risk of hypertension.
