This study reports the results of a worksite weight loss program which allowed female hospital and nursing home employees to enroll in a worksite weight loss program as individuals or as part of a group. After 8 weeks, employees (irrespective of group versus individual participation) lost an average of 6.2 lb and 1.5% body fat. The initial weight, body fat, and body mass index reductions were all significantly greater, in absolute and percentage terms, among group participants than individual participants. Weight reduction averaged 7.6+1.1 lb for group participants and 4.2+6.4 lb for individual participants; body fat reduction was 1.7+1.3% for group participants and 0.9+1.3% for individual participants. Exercising more frequently was significantly associated with weight loss in those participating as a group, while following a written diet plan was significantly associated with weight loss in those participating as individuals.
本研究报告了一项工作场所减肥计划的结果，该计划允许女性医院和养老院员工以个人身份或作为团体的一部分参加工作场所减肥计划。8周后，员工（无论团体参与还是个人参与）平均减重6.2磅，体脂减少1.5%。从绝对值和百分比来看，团体参与者的初始体重、体脂和体重指数降低幅度均显著大于个人参与者。团体参与者平均减重7.6±1.1磅，个人参与者平均减重4.2±6.4磅；团体参与者体脂减少1.7±1.3%，个人参与者体脂减少0.9±1.3%。团体参与者中，更频繁锻炼与体重减轻显著相关，而个人参与者中，遵循书面饮食计划与体重减轻显著相关。
