Abstract

Prediabetes and Type 2 diabetes mellitus (T2DM) is increasingly prevalent and both conditions have a variety of comorbidities. There are many programs aimed at the reduction or prevention of prediabetes and/or T2DM. However, only a few studies have evaluated the effect of intervention duration and evidence-based frameworks on specific populations at risk for prediabetes or T2DM. This review evaluated evidence-based lifestyle intervention programs to determine whether the duration of programming relates to the efficacy of evidence-based lifestyle change interventions. The aim was to assess relevant outcomes of these interventions in prediabetic or T2DM individuals aged 45 and older. The PRISMA framework was followed. Searches systematically screened and evaluated 2654 articles. Thirteen articles met the inclusion/exclusion criteria. Databases searched included: PubMed; SCOPUS; ProQuest; Biomed Central; SpringerLink; ScienceDirect; EBSCOHost; JSTOR; Taylor & Francis; Wiley Online; BioOne; CINAHL; SAGE Journal; and Google Scholar (2009–2022). Identifying the most effective timeframe for lifestyle intervention programming to reduce the risks associated with prediabetes/T2DM can help providers develop appropriate educational initiatives for patients at risk for pre-diabetes and/or T2DM. After screening, there were 13 studies which met the review criteria. All of the studies included in this comparative review used evidence-based interventions. Evidence-based lifestyle intervention programs that are ≥12 months produced significant and consistent results in mediating outcomes related to prediabetes/T2DM than <12-month programs in adults aged 45 years and older.
