Health behavior characteristics and all-cause mortality

چکیده
OBJECTIVE To examine the potential dose-response relationship between four positive health characteristics (i.e., normal body mass index, physically active, healthy diet and non-smoker) and all-cause mortality. METHODS Data from the 2003-2006 NHANES were used (20 + years; N = 5844), with follow-up through 2011. Participants wore an ActiGraph 7164 accelerometer over a period of up to 7 days to assess physical activity. Dietary behavior and smoking were assessed via self-report. Body mass index was measured using standard procedures. RESULTS There was a clear dose-response relationship between the number of positive health characteristics and all-cause mortality. After adjusting for age, gender, race-ethnicity and comorbid illness, and compared to those with 0 positive health characteristics, those with 1, 2, 3, and 4, respectively, had a 39% (HR = 0.61; 95% CI: 0.40-0.94), 48% (HR = 0.52; 95% CI: 0.34-0.80), 62% (HR = 0.38; 95% CI: 0.22-0.64) and 88% (HR = 0.12; 95% CI: 0.05-0.29) reduced risk of all-cause mortality. CONCLUSIONS Adoption of more positive health characteristics is associated with greater survival.

Growing evidence has linked positive psychological attributes like optimism to a lower risk of poor health outcomes, especially cardiovascular disease. It has been demonstrated in randomized trials that optimism can be learned. If associations between optimism and broader health outcomes are established, it may lead to novel interventions that improve public health and longevity. In the present...

In this paper, we examine black-white differences in cause-specific mortality during the 1980s when blackwhite disparities in mortality widened in the United States. We group causes of death to those amenable to medical intervention, those closely linked to health behaviors or residential location, and all other causes combined. At older ages, we treat cardiovascular disease, stroke, and forms ...
