Prevention-oriented life styles and diffusion of cholesterol screening and awareness: Massachusetts behavioral risk...

Universal screening of the adult population for detection of elevated serum cholesterol has been recommended. We examined the relation of eight risk factors for morbidity and mortality (hypertension, overweight, inactivity, tobacco use, safety belt nonuse, binge alcohol consumption, driving after alcohol consumption, and chronic alcohol consumption) to adoption of cholesterol screening and to awareness of cholesterol level. Data were collected through the Massachusetts Behavioral Risk Factor Surveillance System between 1987 and 1991 (mean number of respondents interviewed annually, 1240). We compared trends in prevalence of cholesterol screening and awareness within risk groups defined on the basis of the presence or absence of each risk factor. Cholesterol screening prevalence increased from 46.8% in 1987 to 67.9% in 1991. Overweight and hypertensive respondents were more likely to have been screened than nonoverweight or normotensive respondents; for the other six risk factors, individuals at increased risk were less likely to have been screened. The difference in cholesterol screening prevalence between increased-risk and lower-risk respondents increased between 1987-1988 and 1990-1991 for four risk factors. Prevalence of awareness of cholesterol level increased from 7.8% in 1987 to 35.4% in 19991. Trends by risk status were comparable to those observed for cholesterol screening. Individuals already motivated toward a preventive life style appear to be those most likely to avail themselves of a new prevention possibility.
