Connection Between Depression, Sexual Frequency, and All-cause Mortality: Findings from a Nationally Representative Study

Abstract

We used the 2005–2010 National Health and Nutrition Examination Survey (NHANES), constructed to evaluate health of adults in the United States using consolidated data from interviews and physical exams that were conducted to obtain data for this study. The analysis sample was representative of noninstitutionalized US adults aged 20–59 years. When considering sexual frequency, overall, only female participants with lower sexual frequency were at a higher risk of all-cause death in a dose-response manner with a hazard ratio (HR) of 1.70 (95% CI 1.38–2.10, p trend <52 times/year vs. ≥52 times/year), the adjusted HR was elevated [2.97 (CI 1.20–7.32, p =.02)] among individuals who had depression and low sexual frequency, but it was close to 1.0 (1.75, CI 0.50–6.07, p =.36) among individuals who had depression and high sexual frequency after adjusting for medical (obesity) and demographic (age, gender, education, and ethnicity) risk factors, indicating a 197% increase in mortality among individuals with low sexual frequency and depression than depression alone. Sexual activity is important for overall cardiovascular health possibly due to reduction of heart rate variability and blood flow increase.
