Age Differences in the Association of Severe Psychological Distress and Behavioral Factors with Heart Disease

Abstract EN

Few studies have examined the risk factors of serious psychological distress (SPD) and behavioral factors for heart disease separately stratified as young (18–44 years), middle aged (45–64 years), and elderly (65 years or older).

A total of 3,540 adults with heart disease and 37,703 controls were selected from the 2005 California Health Interview Survey.

Data were weighted to be representative and adjusted for potential undercoverage and nonresponse biases.

Multiple logistic regression models were used to estimate the associations of the factors with heart disease at different ages.

The prevalence of SPD was 8% in cases and 4% in controls, respectively.

For young adults, SPD and higher federal poverty level (FPL) were associated with an increased risk of heart disease while for middle-aged adults, SPD, past smoking, lack of physical activity, obesity, male, and unemployment were associated with an increased risk of heart disease.

In addition, SPD, past smoking, lack of physical activity, obesity, male, unemployment, White, and lower FPL were associated with an increased risk of heart disease in elderly.

Our findings indicate that risk factors for heart disease vary across all ages.

Intervention strategies that target risk reduction of heart disease may be tailored accordingly.
