不同肥胖度之員工參加職場體重管理計劃之成效－－以某健康促進醫院為例

A Study of the Effectiveness of Weight Loss Competition among Health Promoting Hospital Employees with Different Body Mass Index Levels

目的：探討職場不同肥胖度之員工參加體重管理計劃之減重成效。方法：某健康促進醫院101年體重管理計劃招募身體質量指數（Body Mass Index BMI）≧20之員工，以自我導向方式參加減重競賽或體重自主登錄，本研究分析不同體位員工參加體重管理計劃體重、BMI、減重百分比之減重成效。結果：在101年體重管理計劃共602位參加，參加者86.7%為女性；平均年齡37.3±9.1歲，平均體重為61.3±10.0公斤；BMI23.7±3.2kg/m^2。計劃結束後平均-0.6±2.5公斤，BMI-0.2±0.9kg/m2，過重肥胖者減重成效優於標準體位。計劃參與週數及磅重次數較多者減重成效較佳。結論：在職場上推動員工自主性高減重競賽，具有正面成效，參與員工遵從性高可得到較佳的減重成效，但計劃內容及方式若能依職場員工之需求適度調整並增加誘因，健康體重管理計劃將可吸引更多員工的參與。

This study investigated the outcomes in a worksite weight loss competition among hospital employee with different body mass index levels. 602 completers (86.7% female; age=37.3±9.1; body weight=61.3±10.0kg) showed losing 0.6±2.5kg, BMI -0.2±1.0 kg/m^2. Participants achieved a clinically significant weight loss≥5% compliance to an intervention programme than the other group with weight loss≤5%.These results suggest that the worksite weight loss competition to prevent weight gain. Higher compliance to a programme were associated with weight loss outcomes. Employees in the workplace to promote self-directed weight loss competition has a positive effect. Employees get involved in high compliance better weight reduction results. The modified weight management program which to increase incentives will attract more employees to participate.
