The purpose of this study was to assess the costs and impact of a nutrition education program following a cholesterol screening.
Forty work-sites were randomly assigned to one of two educational interventions: a "usual" intervention of 5 minutes of counseling, or a "special" intervention of 2 hours of behaviorally based education on dietary changes to lower serum cholesterol. Costs were monitored, and cholesterol levels were retested 6 and 12 months later.
The total per-person cost for screening and the educational intervention was about $50. Cholesterol levels differed little between the two intervention groups 6 months after screening, but after 12 months those in the special intervention worksites showed a 6.5% drop in cholesterol, whereas those at the usual intervention worksites showed a drop of only 3.0%. Hence a 3.5% cholesterol reduction was attributable to the special intervention.
A behaviorally based nutrition education program following cholesterol screening can have a meaningful impact on long-term cholesterol levels at a low cost. Nutrition education in work-sites may therefore be a useful way to lower the risk of heart disease in communities.
本研究旨在评估胆固醇筛查后营养教育项目的成本及影响。
40个工作场所被随机分配到两种教育干预措施之一：一种是5分钟咨询的“常规”干预，另一种是基于行为的2小时饮食改变以降低血清胆固醇的教育的“特殊”干预。监测成本，并在6个月和12个月后重新检测胆固醇水平。
筛查和教育干预的人均总成本约为50美元。筛查6个月后，两个干预组之间的胆固醇水平差异不大，但12个月后，接受特殊干预的工作场所的胆固醇水平下降了6.5%，而接受常规干预的工作场所的胆固醇水平仅下降了3.0%。因此，特殊干预导致胆固醇水平降低了3.5%。
胆固醇筛查后基于行为的营养教育项目可以以低成本对长期胆固醇水平产生有意义的影响。因此，工作场所的营养教育可能是降低社区心脏病风险的一种有用方法。
