社会支持可能与改善饮食和体力活动有关--这是超重和肥胖的决定因素。健康计划越来越多地针对工作场所。目的是评估工作场所社会支持与饮食行为、体力活动和体重指数(BMI)的关系。从2005年到2007年，通过促进活动和饮食变化获得了来自34个工作地点的2878名员工的基线数据，这是一项在大西雅图进行的团体随机减肥干预措施。工作场所的社会支持、饮食、体力活动和体重指数通过自填式问卷进行评估。主成分分析被应用于工作组问题。为了调整设计效果，采用了随机效果模型。没有发现与工作场所社会支持和BMI或许多肥胖行为有关。然而，与工作场所社会支持较低的个体相比，工作场所社会支持较高的个体的平均体力活动得分高14.3%(95%CI：5.6%~23.7%)，水果和蔬菜的平均摄入量高4%(95%CI：1%~7%)。我们的发现并不支持工作场所较高的社会支持与肥胖行为之间的确凿关系，除了体力活动和水果和蔬菜的摄入。需要进一步的研究来证实这些关系，并评估工作场所的社会支持如何影响试验结果。
Social support may be associated with improved diet and physical activity—determinants of overweight and obesity. Wellness programs increasingly target worksites. The aim was to evaluate the relationship between worksite social support and dietary behaviors, physical activity, and body mass index (BMI). Baseline data were obtained on 2,878 employees from 2005 to 2007 from 34 worksites through Promoting Activity and Changes in Eating, a group-randomized weight reduction intervention in Greater Seattle. Worksite social support, diet, physical activity, and BMI were assessed via self-reported questionnaire. Principal components analysis was applied to workgroup questions. To adjust for design effects, random effects models were employed. No associations were found with worksite social support and BMI, or with many obesogenic behaviors. However, individuals with higher worksite social support had 14.3% higher (95% CI: 5.6%-23.7%) mean physical activity score and 4% higher (95% CI: 1%–7%) mean fruit and vegetable intake compared to individuals with one-unit lower support. Our findings do not support a conclusive relationship between higher worksite social support and obesogenic behaviors, with the exception of physical activity and fruit and vegetable intake. Future studies are needed to confirm these relationships and evaluate how worksite social support impacts trial outcomes.
