A random telephone survey was conducted to measure the public's willingness to participate in a boycott of popular consumer products manufactured by corporations owned by tobacco companies. Results suggest a strong interest in such a boycott. Previous boycott experiences, attitudes, and smoking statuses significantly predicted subjects' willingness to participate. Age was inversely related to willingness to participate, while sex, income, ethnicity, and education were not related to this variable.

Racial disparities in pregnancy outcomes: the role of prenatal care utilization and maternal risk status.
Distinct black-white differences in pregnancy outcome and prenatal care utilization have been a persistent feature of U. S. natality-related statistics. ⋯ Distinct racial differences in birth weight and gestational age distributions were observed within equivalent maternal risk and prenatal care categories, with whites having an approximately 200-gram mean birth weight and five-day mean gestational age advantage compared to blacks. In this analysis of more than 650,000 cases, low-risk blacks adequately utilizing prenatal care had a lower mean birth weight (3,266 grams) and a higher neonatal mortality rate (6.6) than low-risk, inadequate-care whites (3,302 grams; 6.1).

To understand the external validity of experimental studies, it is important to estimate the extent to which the participants are representative of the general population. This paper describes recruitment methods and considers the representativeness of participants in the San Diego Family Health Project. The study was designed to experimentally evaluate the effectiveness of a family-based behavior change intervention in Anglo and Mexican-American families. ⋯ In separate analyses for Anglo and Mexican-American responders, our data suggested many similarities and a few differences among participant groups. The differences that were observed suggest that participants may already have healthier diets than nonparticipants, although only one of four dietary variables differed by participation status in each ethnic group. The external validity of these data and general recruitment issues are discussed.

As part of the Edgecombe County High Blood Pressure Control Program, a medical record review was conducted within a multispecialty private group practice in the county. The purposes of the review were to assess the relationship between the process of medical care and blood pressure control and to explore the variation in level and impact of medical care by race and sex. At the end of a three-year period, 41 percent of 628 hypertensive patients from the practice had uncontrolled diastolic blood pressure (DBP), as defined by Hypertension Detection and Follow-up Program criteria. ⋯ Hypertensive patients whose physicians were more aggressive in their use of antihypertensive drug therapy were more likely to be controlled. The effect of the level of physician drug aggressiveness tended to be more pronounced for blacks than for whites. Differences by race in exposure to and efficacy of aggressive drug treatment may influence racial variation in blood pressure control.

Clinical research has suggested that isolated systolic hypertension differs from essential hypertension in terms of pathophysiological change. Yet little is known of the descriptive epidemiology of isolated systolic hypertension. This paper examines the prevalence of isolated systolic hypertension in biracial Alameda County, California. ⋯ Comparison with the prevalence estimates of isolated systolic hypertension from biracial, rural Evans County, Georgia, indicated that the Alameda County prevalence was significantly lower for white women (p less than .01), black women (p less than .03), and total population (p less than .01). We posit that the larger number of people under care for essential hypertension is responsible for the lower occurrence of pure, isolated systolic hypertension in Alameda County. The results suggest the importance of female family members in the acceptance and promulgation of health promotion efforts for both essential and isolated systolic hypertension at the population level.
