Abstract
Lower socioeconomic status (SES) is probably the most powerful single contributor to premature morbidity and mortality, not only in the United States but worldwide. Since lower SES groups are more likely to engage in a number of risky health behaviors, it has been tempting to assume that these behaviors are responsible for the health problems that mount as SES decreases—and to draw the logical conclusion that simply by bringing about a reduction in these risky behaviors, the health problems associated with lower SES will disappear. Unfortunately for this hypothesis, as Lantz et al1 show quite convincingly in this issue of THE JOURNAL, 4 important health behaviors—smoking, alcohol consumption, body mass index, and physical activity level—explain no more than a modest "12% to 13% of the predictive effect of income on mortality." By incorporating in this study a nationally representative longitudinal sample with both men and women, the authors overcome the limitations of prior studies that found these and other physical risk factors to account for no more than a third of the excess mortality associated with lower SES.Keywords
