Effectiveness of workplace diabetes prevention programs: A systematic review of the evidence

PurposeThe primary purpose is to review diabetes workplace interventions and the degree to which they improve diabetes-related outcomes in employees diagnosed with or at risk for T2DM.MethodsThree electronic databases and ancestry searches were used to identify peer reviewed articles published in English from 2000 to June 2017.ResultsThe number of participants represented by the 22 selected studies, excluding one large outlier, was 4243. On average, the samples were 57% female and ethnically diverse. Interventions-healthy eating behaviors, physical activity, and/or monitoring and self-managing diabetes and cardiovascular risk factors-were delivered in group sessions of fewer than 20 employees. Programs involved 1-h weekly sessions held during lunch hour or at other times during the workday for 12 to 24 weeks. Study outcomes, commonly measured at 6 and/or 12 months, were consistently positive.ConclusionThe literature search uncovered beginning evidence that workplace interventions hold promise for preventing diabetes and/or its complications. More rigorous, creatively designed, workplace studies, are needed for employees at high-risk for developing diabetes.Practice implicationsImplications include the need for employer education about the benefits of employer support for such programs and attention to motivational strategies so employees will take full advantage of programs that are offered
