很少有现场试验检查糖尿病预防干预对心理和行为结果的影响。因此，我们评估了工作场所生活方式干预对心理社会结果、食物组摄入和身体活动步数（PA）的影响。本研究于2012年10月至2014年5月在美国某大学工作场所对患有糖尿病前期的员工进行了为期3个月的随机前测/后测对照组设计。实验组（n = 35）给予为期16周的分组干预，对照组（n = 33）给予常规护理。重复测量方差分析比较不同时间组间结果的变化。干预后两组之间与饮食和PA相关的自我效能感存在显著差异；目标承诺和难度；对减肥和身体健康的满意度；同伴社会对健康饮食的支持；提出解决问题的备选方案；水果、肉类、鱼类、家禽、坚果和种子的摄入量（均p < 0.05）。实验组干预后的步数显著增加（p = 0.0279），在研究结束时报告完成工作的可能性显著增加（p = 0.0231）。工作场所试验促进了可改变的社会心理结果、饮食模式和步数的改善；对糖尿病预防的长期影响值得进一步研究。网站可以成为糖尿病预防工作的有效场所。生活方式干预促进了更健康饮食的采用。参与干预的参与者增加了每周的体力活动步数。实现了对健康生活方式的目标承诺和信心。
Few worksite trials have examined the impact of diabetes prevention interventions on psychological and behavioral outcomes. Thus, the impact of a worksite lifestyle intervention on psychosocial outcomes, food group intake, and step counts for physical activity (PA) was evaluated. A randomized pretest/posttest control group design with 3-month follow-up was employed from October 2012 to May 2014 at a U.S. university worksite among employees with prediabetes. The experimental group (n = 35) received a 16-week group-based intervention while the control group received usual care (n = 33). Repeated measures analysis of variance compared the change in outcomes between groups across time. A significant difference occurred between groups post-intervention for self-efficacy associated with eating and PA; goal commitment and difficulty; satisfaction with weight loss and physical fitness; peer social support for healthful eating; generation of alternatives for problem solving; and intake of fruits, meat, fish, poultry, nuts, and seeds (all ps < .05). The experimental group significantly increased step counts post-intervention (p = .0279) and were significantly more likely to report completing their work at study end (p = .0231). The worksite trial facilitated improvement in modifiable psychosocial outcomes, dietary patterns, and step counts; the long-term impact on diabetes prevention warrants further investigation. ClinicalTrials.gov identifier: NCT01682954 The worksite can be an effective venue for diabetes prevention efforts. The lifestyle intervention facilitated the adoption of a more healthful diet. Intervention participants increased weekly step counts toward physical activity. Goal commitment and confidence regarding a healthy lifestyle were achieved.
