We conducted free, voluntary, public cholesterol screenings in supermarkets in the Rochester, New York, area during a four-month period for demonstration and research purposes. We assessed demographic characteristics and attendance patterns of the 8,583 participants. Compared with 1980 census data for the same census tracts, our participants were likelier to be white, older, female, and better educated than the general population in the area. Most screenees knew about the screenings in advance, and 79% came to the store just for screening. Weekend and weeknight screenings attracted more men and more younger people, in comparison to weekday screenings. However, referral rates based on high cholesterol (HC) test results were similar during all screening times. Overall, 22% of screenees reported a previous diagnosis of HC, but in the highest cholesterol-level group, 45% of screenees reported a history of HC. Previous awareness of HC did not vary according to screening time. These findings indicate that, like other screenings, cholesterol screenings in a public setting do not attract a representative sample of the whole population. The screenings did, however, attract a large number of high-risk individuals, many of whom had no prior awareness of HC. These results should be valuable in planning and targeting future cholesterol screenings.
出于示范和研究目的，我们在纽约州罗切斯特地区的超市进行了为期四个月的免费、自愿、公开的胆固醇筛查。我们评估了8583名参与者的人口统计学特征和出勤模式。与同一普查区的1980年人口普查数据相比，我们的参与者比该地区的普通人群更有可能是白人、年龄较大、女性且受教育程度更高。大多数受检者提前知道了筛查活动，79%的人到商店只为了进行筛查。与工作日的筛查相比，周末和工作日晚上的筛查吸引了更多男性和更年轻的人。然而，在所有筛查时间段内，基于高胆固醇（HC）检测结果的转诊率相似。总体而言，22%的受检者报告曾被诊断为HC，但在胆固醇水平最高的组中，45%的受检者报告有HC病史。对HC的既往知晓情况在不同筛查时间段并无差异。这些发现表明，与其他筛查一样，在公共场所进行的胆固醇筛查并未吸引到具有代表性的全体人群样本。不过，这些筛查确实吸引了大量高危个体，其中许多人此前并不知道自己患有HC。这些结果对于规划和定位未来的胆固醇筛查应具有重要价值。
