Personal health practices, health status, and expected control over future health.

Data from Wave 1 of the National Survey of Personal Health Practices and Consequences were used to examine the association between perceived control over future health and 13 health behavior indices. Analyses were conducted within three strata of health status, defined by a cross-tabulation of subjective and functional health ratings. Greater control expected over future health was associated with 11 of the 13 practices in the stratum of persons in best health, but with only 2 practices in the lowest and 3 practices in the middle health strata. Age, gender, education, and a regular source of health care were also important predictors. Overall, persons in the lowest health stratum had the fewest number and least consistent set of predictors of preventive practices. Although the rationales proposed for following preventive practices often rely upon individuals' favorable outlooks on their futures, the present data suggest that background health status may mediate the relationship. Health status can be viewed as a personal resource, which provides an opportunity for predispositions such as perceived control over future health to be consistently expressed in behavior. Attempts to develop theoretical frameworks and intervention programs that are applicable to several behaviors appear to face a difficult challenge, since few of the predictors were consistently related to more than a small number of the 13 practices. Health promotion programs may need to include health status as an additional characteristic around which to structure both the content of recruitment messages, and expectations for persons who will be relatively more easy or difficult to reach.
