OBJECTIVES
A randomized trial was conducted to evaluate the effectiveness of a work-site health promotion program in reducing obesity and the prevalence of cigarette smoking.
METHODS
Thirty-two work sites were randomized to treatment or no treatment for 2 years. Treatment consisted of health education classes combined with a payroll-based incentive system. Evaluation was based on cohort and cross-sectional surveys.
RESULTS
Of 10,000 total employees in treatment work sites, 2041 and 270 participated in weight control and smoking cessation programs, respectively. Weight losses averaged 4.8 lbs, and 43% of smoking participants quit. Net 2-year reductions in smoking prevalence in treatment vs control work sites were 4.0% and 2.1% in cross-sectional and cohort surveys, respectively. No treatment effect was found for weight. Treatment effects for smoking prevalence and weight were both positively correlated with participation rates in the intervention programs (r = .45 for smoking and r = .55 for weight).
CONCLUSIONS
This work-site health promotion program was effective in reducing smoking prevalence at a cost that is believed to make the investment worthwhile.
目的
开展一项随机试验，以评估工作场所健康促进计划在降低肥胖率和吸烟率方面的有效性。
方法
32个工作场所被随机分为接受治疗组或不接受治疗组，为期2年。治疗包括健康教育课程和基于工资的激励系统。评估基于队列研究和横断面调查。
结果
在接受治疗的工作场所的10000名员工中，分别有2041人和270人参加了体重控制和戒烟计划。体重平均减轻4.8磅，43%的吸烟参与者戒烟。在横断面调查和队列研究中，治疗组与对照组工作场所吸烟率的2年净下降率分别为4.0%和2.1%。未发现对体重有治疗效果。吸烟率和体重的治疗效果均与干预计划的参与率呈正相关（吸烟r = 0.45，体重r = 0.55）。
结论
这项工作场所健康促进计划在降低吸烟率方面是有效的，其成本被认为使投资具有价值。
