摘要美国糖尿病预防计划（DPP）显示，以增加体力活动（PA）和减肥为目标的行为生活方式干预计划在预防2型糖尿病和降低心血管疾病（CVD）风险方面有效。DPP生活方式干预的修改版本正在被转化为不同的社区环境，并已成功地降低体重和改善代谢标志物。然而，在这些社区翻译干预工作中，对PA水平的全面评估是罕见的。本研究的目的是评估基于DPP的社区生活方式干预对改善PA水平的有效性。223名有2型糖尿病和/或CVD风险的超重成年人被随机分配（立即或6个月延迟开始组）接受12个月基于DPP的生活方式干预。在基线和干预后用可调整活动问卷评估过去一个月的PA水平。使用简单和混合效应回归模型来确定组间和组内PA水平随时间的变化。PA水平从基线至6个月变化的组间平均差异表明，与延迟开始组相比，干预组的改善显著更大（+6.72 MET·h·wk−1（SE = 3.01），P = 0.03）。检查从基线到干预后的组内变化，我们发现平均PA水平在干预后6个月和12个月分别显著增加了+14.69 MET·h·wk−1（SE = 1.43）和+9.50 MET·h·wk−1（SE = 1.40）。在调整基线PA水平和季节后，PA变化在6个月和12个月时均抵消至约+10 MET·h·wk−1（所有，P < 0.01）。除季节外，性别对PA水平的变化有影响。总之，这种基于社区的生活方式干预显著增加了2型糖尿病和CVD风险超重成年人的PA水平，即使在调整了关键变量后。
ABSTRACT A behavioral lifestyle intervention program with goals of increasing physical activity (PA) and losing weight was shown to be efficacious in preventing type 2 diabetes and decreasing risk of cardiovascular disease (CVD) in the US Diabetes Prevention Program (DPP). Modified versions of the DPP lifestyle intervention are being translated into diverse community settings and have been successful in decreasing weight and improving metabolic markers. However, comprehensive evaluations of PA levels within these community translation intervention efforts are rare. The purpose of this study is to evaluate the effectiveness of a DPP-based community lifestyle intervention for improving PA levels. Two hundred twenty-three overweight adults at risk for type 2 diabetes and/or CVD were randomized (immediate or 6-month delayed-start group) to a 12-month DPP-based lifestyle intervention. The past month's PA level was assessed at baseline and postintervention with the Modifiable Activity Questionnaire. Simple and mixed-effects regression models were used to determine changes in the PA level between and within groups over time. The between-group mean difference for change in PA levels from baseline to 6 months indicated significantly greater improvement in the intervention compared with the delayed-start group (+6.72 MET·h·wk−1 (SE = 3.01), P = 0.03). Examining combined within-group change from baseline to postintervention, we found that mean PA levels significantly increased by +14.69 MET·h·wk−1 (SE = 1.43) and +9.50 MET·h·wk−1 (SE = 1.40) at 6 and 12 months postintervention, respectively. This PA change offset to approximately +10 MET·h·wk−1 at both 6 and 12 months after adjusting for the baseline PA level and season (all, P < 0.01). Other than the season, sex impacted on change in the PA level. In conclusion, this community-based lifestyle intervention significantly increased PA levels among overweight adults at risk for type 2 diabetes and CVD, even after adjusting for key variables.
