Effectiveness of behavioral intervention programs for preventing and managing diabetes in adults: a systematic review of evidence
摘要
Diabetes is a growing global health issue that can have serious consequences. As the value of behavioral intervention programs for preventing and managing this disease in adults becomes more evident, this study aimed to assess the effectiveness of these programs in mitigating and managing diabetes among adult populations.
MethodsA comprehensive search strategy was employed utilising a range of electronic databases like Google Scholar, PubMed, Science Direct, Medline, PsycINFO, and Cumulative Index to Nursing and Allied Health Literature. Only research articles written in English and published between 2012 and 2024 were included. Included were articles focusing on behavioral interventions targeting glycemic control (HbA1c) in adults (≥ 18 years) with or at risk for type 2 diabetes. The review adhered to PRISMA guidelines, with 39 studies meeting inclusion criteria after screening 1,156 initial records.
ResultsThirty-nine studies met inclusion criteria. Of these, 28 reported significant glycemic improvements, with mean HbA1c reductions of − 0.3% to − 0.7% (Cohen’s d ≈ 0.28). Dietary and culturally tailored programs achieved the largest reductions, while CBT and technology-assisted approaches showed modest but clinically relevant effects. Prevention trials reduced diabetes incidence by 20–30% compared with controls.
ConclusionBehavioral interventions effectively improve glycemic control and prevent diabetes in at-risk populations. Key components of success include individualized support, multidisciplinary care, and technology integration. These findings underscore the potential of behavioral strategies to complement clinical diabetes management globally.
