Marital Failure and Subsequent Heart Failure: A Prospective Study

Area of Science:

• Cardiovascular Health
• Social Determinants of Health
• Epidemiology

Background:

• Loss of a stable spousal relationship is linked to increased morbidity and mortality.
• Limited evidence exists on the association between marital failure and subsequent heart failure (HF) risk.
• This study investigates the impact of marital failure on heart failure incidence.

Purpose of the Study:

• To examine the association between marital failure and the risk of subsequent heart failure (HF).
• To identify specific subgroups, such as those with higher education or poor lifestyle, who may be more vulnerable.

Main Methods:

• Utilized data from two large prospective cohort studies (Kailuan Study I and II) with 125,042 participants.
• Marital status was self-reported; heart failure (HF) cases were identified through multiple data sources.
• Cox proportional hazards models were employed to analyze associations, adjusting for various covariates.

Main Results:

• Marital failure was associated with a 30% increased hazard ratio for heart failure (HF) (HR, 1.30; 95% CI, 1.14-1.49) compared to marital stability.
• The association was significantly stronger in individuals with higher educational attainment.
• A poorer lifestyle score (smoking, drinking, physical activity, diet, BMI) also amplified the HF risk associated with marital failure.

Conclusions:

• Marital failure is a significant risk factor for subsequent heart failure (HF) in a large prospective cohort.
• Individuals with higher education and unhealthy lifestyle habits are particularly susceptible to this increased risk.
• Marital failure should be considered a noteworthy socioeconomic factor for identifying at-risk populations and developing targeted health interventions.
