This study examines age and gender differences in risk factors for isc
hemic heart disease mortality using data from the 1986 National Mortal
ity Followback Survey. The sample includes 4,206 decedents over the ag
e of 30 for whom the proxy respondent was a family member. Risk factor
s are grouped according to Acquired Risks, living arrangements, occupa
tional prestige, health practices, and Biological Risks, body mass, fa
mily history of heart disease, diabetes, and hypertension, to assess d
ifferential impact, with demographic controls. Logistic regression rev
eals that age differences are more pronounced than gender differences
and that biological risks are stronger than acquired risks. Findings s
uggest that increasing health practices among younger individuals and
treating co-morbidities among older individuals may be most likely tar
gets for successful intervention.
