A randomized community trial to increase mammography utilization among low-income women living in public housing.

BACKGROUND: A randomized trial was conducted to evaluate the impact of a community-based intervention on mammography use among low-income women living in public housing. METHODS: All 41 public housing high-rise buildings were randomized to treatment and delayed treatment (control) conditions. After a cross-sectional baseline survey, an intervention called Friend to Friend was conducted in the treatment buildings by American Cancer Society and building resident volunteers. The intervention consisted of a health professional talk, small group discussions, and an opportunity to request assistance in obtaining a mammogram or mammogram reminder. A second cross-sectional survey was conducted to measure differences in screening rates between the study groups. RESULTS: Participation in the intervention averaged 27%. The study groups were equivalent at baseline. At follow-up, the proportion of women age 50-79 years who reported mammography screening in the previous 15 months was significantly higher in the treatment group (64%) than in the control group (52%). Breast cancer knowledge, attitudes, and beliefs did not differ between groups. CONCLUSIONS: These findings suggest that a multidimensional intervention which reaches women within their social environment and uses community volunteers can increase mammography utilization among women in public housing.

Seasonal variation in plasma cholesterol distributions: implications for screening and referral.

In 3,377 men and 3,900 women who participated in a community-based plasma cholesterol screening program, we found a significant cyclic time-trend in cholesterol levels, with maximum peak in January. The 95% confidence interval (CI) of the peak to trough distance was 5.8-13.8 mg/dL (0.15-0.36 mmol/L) in men, corresponding to 2.6%-6.3% of the average cholesterol level. Corresponding figures for women were 2.0-9.3 mg/dL (0.05-0.24 mmol/L) or 1.0%-4.6%. Applying the cutoff level for high cholesterol risk proposed by the National Cholesterol Education Program (< or = 240 mg/dL [6.21 mmol/L]) to sex-specific bimonthly distributions, we found a statistically significant variation in prevalence, attributable to seasonal trends, in men (P < .01), but not in women. In men, the age-adjusted prevalence in winter (25.4%) was double that in the summer (13.5%). Seasonal variation is an important determinant of the prevalence of hypercholesterolemia in men and should be considered in patient follow-up and screening.

Population screening and referral for hypercholesterolemia.

To determine the potential effect of screening on referral patterns, an adult population sample (4,404 men, 5,164 women, 20-69 years of age) was systematically recruited and screened for hypercholesterolemia and then analyzed by different cholesterol referral recommendations. Using levels suggested by the Lipid Research Clinics Coronary Primary Prevention Trial (greater than or equal to 265 mg/dL), 7.3% of men and 5.8% of women would be referred for follow-up. With the suggested recommendations of the National Cholesterol Education Program (NCEP), (greater than or equal to 200 mg/dL), 49.2% of men and 40.2% of women would be referred. The use of age-related definitions of the NIH Consensus Conference on Lipid Lowering results in 28.0% referrals in men and 21.8% in women. From this population, hypercholesterolemia subjects (greater than or equal to 265 mg/dL at screening; n = 624) were invited for a second cholesterol determination (58% returned), which found 36% below the 265 mg/dL level. Population screening for cholesterol is likely to produce large numbers of patients for follow-up, with the actual numbers strongly dependent on cutoff levels and age-sex distributions. Referral and follow-up of these patients may place a significant load on an unprepared health care community.

Impact of the Mammography Quality Standards Act on access in Minnesota.

OBJECTIVES: The Minnesota Department of Health surveyed registered mammography facilities to assess their accreditation status prior to full implementation of the Federal Mammography Quality Standards Act (MQSA), which mandated accreditation of all mammography facilities by October 1994; to strategize on the steps that might be taken to avoid closure of facilities; and to evaluate the ultimate impact of the law on the availability of mammography in Minnesota. METHODS: Mammography facilities registered with the Radiation Control Section of the state health department were surveyed five months prior to and four months after the October 1994 deadline. Data collected included accreditation status, plans for continuing service, number of mammograms performed, and areas in which technical assistance was needed. In October 1995, the number and distribution of facilities were determined from the Radiation Control Section registration database. RESULTS: The pre-MQSA survey of 182 respondents found that 96% planned to continue mammography services but only 49% were accredited. The remaining 51% had applications in progress. In the post-MQSA survey, 70% of 182 facilities were found to be accredited, and 30% were operating under provisional certification. As of October 1995, although six facilities had closed, there was a net gain of four mammography facilities providing on-site service. CONCLUSIONS: Despite fears to the contrary, access to mammography in the state of Minnesota was not adversely affected by full implementation of the Mammography Quality Standards Act.
