OBJECTIVE -To evaluate the efficacy of self-management education on GHb in adults with type 2 diabetes. Medline (1980), Cinahl (1982, and the Educational Resources Information Center database (ERIC) (1980 -1999), and we manually searched review articles, journals with highest topic relevance, and reference lists of included articles. Studies were included if they were randomized controlled trials that were published in the English language, tested the effect of self-management education on adults with type 2 diabetes, and reported extractable data on the effect of treatment on GHb. A total of 31 studies of 463 initially identified articles met selection criteria. We computed net change in GHb, stratified by follow-up interval, tested for trial heterogeneity, and calculated pooled effects sizes using random effects models. We examined the effect of baseline GHb, follow-up interval, and intervention characteristics on GHb.
RESEARCH DESIGN AND METHODS -We searched for English language trials inRESULTS -On average, the intervention decreased GHb by 0.76% (95% CI 0.34 -1.18) more than the control group at immediate follow-up; by 0.26% (0.21% increase -0.73% decrease) at 1-3 months of follow-up; and by 0.26% (0.05-0.48) at Ն4 months of follow-up. GHb decreased more with additional contact time between participant and educator; a decrease of 1% was noted for every additional 23.6 h (13.3-105.4) of contact.CONCLUSIONS -Self-management education improves GHb levels at immediate followup, and increased contact time increases the effect. The benefit declines 1-3 months after the intervention ceases, however, suggesting that learned behaviors change over time. Further research is needed to develop interventions effective in maintaining long-term glycemic control.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
