Newswise — STONY BROOK, N.Y., April 8, 2011 – In a meta-analysis of 42 studies with data on 20 million people regarding the relationship between unemployment and the risk of death, a team of researchers at Stony Brook University found that the risk of death was 63 percent higher in those who experienced an episode of unemployment than those who did not. They also found that the increased risk was greater for men (78 percent) than for women (37 percent). Reported in Social Science & Medicine, the overall study results reveal that the relationship between unemployment and mortality risk has remained constant for the past 50 years.
“Our study results clearly indicate that unemployment is not just bad for your pocketbook; it’s also bad for your health,” says Joseph E. Schwartz, Ph.D., Senior Author, Professor of Psychiatry and Behavioral Science, Stony Brook University School of Medicine, and Visiting Professor, Department of Medicine and Psychiatry, Columbia University. “The results suggest a causal relationship between unemployment and higher risk of death, as well as the need to identify strategies to minimize the adverse health effects of unemployment.”
Dr. Schwartz points out that while unemployment is always an issue for society, the current economic crisis and unemployment rates intensify the need to research the relationships between unemployment, health risks, and premature death. According to the U.S. Department of Labor, the national unemployment rate reached 9.6 percent in August 2010, near its highest level in 25 years. The rate continues to be high, at 8.8 percent in March 2011.
The study, titled “Losing life and livelihood: A systematic review and meta-analysis of unemployment and all-cause mortality,” included an analysis of working-age men and women mainly in Western countries over a 40-year period. Employment and unemployment were documented in the studies for people in all phases of their careers. Individuals were followed for different lengths of time in the various studies.
The researchers also found that for those who were younger (under age 50) and who experienced an episode of unemployment, the risk of death was greater (approximately 75 percent) than for those who were 50 or older (25 percent) experiencing the same.
“Those studies that followed people for more than 10 years showed a weaker relationship between unemployment and risk of death,” adds David J. Roelfs, first author, and a doctoral candidate in the Department of Sociology at Stony Brook University. “This finding strongly suggests that the increase in risk is greater during an episode of unemployment and the initial 10 years thereafter.”
Dr. Schwartz and colleagues emphasize that future research should focus on possible mediating, moderating, and confounding factors, and on whether the risk of death could be modified in individuals, either at the health care system level or individual level. Some methods they suggest could include public health initiatives that target unemployed people for more aggressive cardiovascular screening, or targeted interventions to help unemployed individuals reduce risk-taking behaviors.
The research was supported in part by a grant from the National Institutes of Health. Other study co-authors include: Eran Shor, a graduate student in the Department of Sociology, Stony Brook University (at the time of the study), and now of the Department of Sociology, McGill University, Montreal, Canada; and Karina W. Davidson, Department of Medicine and Psychiatry, Columbia University.
