Low socioeconomic status is associated with higher mortality, but also
with such health risk behaviors as smoking, alcohol use, sedentary lifestyle,
and increased body weight, which are known to contribute to increased mortality.
Dr Lantz and colleaguesArticle found that these 4 risk behaviors combined accounted
for only 12% to 13% of the predictive effect of income level on mortality.
A related editorialArticle suggests that psychosocial factors might account for the
remaining increased risk.
