Context Depression negatively affects health and well being among older adults, but there have been no nationally representative comparisons of depression prevalence among older adults in England and the United States. Objective The authors sought to compare depressive symptoms among older adults in these countries and identify sociodemographic and clinical correlates of depression in these countries. Design and Setting The authors assessed depressive symptoms in non-Hispanic whites aged 65 years and older in 2002 in two nationally representative, population-based studies: the U.S. Health and Retirement Study and English Longitudinal Study of Ageing. Participants A total of 8,295 Health and Retirement Study respondents and 5,208 English Longitudinal Study of Ageing respondents. Main Outcome Measures The authors measured depressive symptoms using the eight-item Center for Epidemiologic Studies Depression Scale. The authors determined whether depressive symptom differences between the United States and England were associated with sociodemographic characteristics, chronic health conditions, and health behaviors. Results Significant depressive symptoms (Center for Epidemiologic Studies Depression Scale score ≥4) were more prevalent in English than U.S. adults (17.6% versus 14.6%, adjusted Wald test F[1, 1593] = 11.4, p < 0.001). Adjusted rates of depressive symptoms in England were 19% higher compared with the United States (odds ratio: 1.19, 95% confidence interval: 1.01–1.40). U.S. adults had higher levels of education, and net worth, but lower levels of activities of daily living/instrumental activities of daily living impairments, tobacco use, and cognitive impairment, which may have contributed to relatively lower levels of depressive symptoms in the United States. Conclusions Older adults in the United States had lower rates of depressive symptoms than their English counterparts despite having more chronic health conditions. Future cross-national studies should identify how depression treatment influences outcomes in these populations.
