Behavior, lifestyle, and socioeconomic variables as determinants of health status: implications for health policy...

Health promotion has become an official health policy of this country, and it is being pursued through efforts to change individuals' health-related behavior. This approach is based on the assumption that it is in fact an individual's behavior that most directly determines his or her health status. But how good is the evidence that supports this assumption? Specifically, is the evidence sufficient for this assumption to outweigh the long-standing finding that social and economic conditions have a strong relationship to health status? The major support for the behavior approach derives from the coronary heart disease risk-factor studies and the Alameda County Study. In a series of reports over time, the relationship between individuals' health practices and their health status generally, as well as that between heart disease and cancer specifically, have been established by these studies. These observations, however, have not been confirmed when deliberate efforts have been made to change those practices. The evidence in support of the importance of social and economic conditions to health status has been documented through a long series of studies in this country, which have found a direct relationship between individuals' socioeconomic status and their health status. This relationship, however, has not in this country been tested by intervention. Only a few studies have examined the interrelationship between these two approaches to health promotion, but the evidence to date has failed to suggest that either one is the mediator of the other. We must, therefore, conclude that pursuing a policy of health promotion based on either approach to the exclusion of the other would indeed be short-sighted health policy.
