Prevalence, Incidence and Factors Associated with Diabetic Foot in People with Type 2 Diabetes: Systematic Review with Meta-Analysis.

BACKGROUND

Diabetic Foot is a severe chronic complication of diabetes and an important factor in the morbidity of diabetic people, resulting in high health costs and increased risk of death.

OBJECTIVE

To analyze the incidence, prevalence, and risk factors associated with diabetic foot in people with type 2 Diabetes Mellitus.

METHOD: Systematic literature review. Searches in MedLine via PubMed, LILACS, Web of Science, Scopus CINAHL, and Cochrane Library databases were performed. Inclusion of 52 studies. The R program, Metan packages, was used to calculate the meta-analysis. Given the heterogeneity of studies, the random effect was used to calculate the meta-analysis of risk factors.

RESULTS

The meta-analysis showed that the prevalence of diabetic foot was 14% in a hospital setting and 5% in a community setting. The overall prevalence and incidence were 9% and 4%, respectively. Significant risk factors included time of DM (odds ratio [OR] =1.46, confidence interval [CI], 0.36-2.57, P = 0.009), smoking (OR = 1.46, CI, 1.16 -1.85, P< .001), glycated hemoglobin (OR = 0.96, CI, 0.50; 1.42, P< .001), peripheral arterial disease (OR = 3.38, CI, 2.07; 5.53, P < .001) and peripheral neuropathy (OR = 5.88, CI, 2.39-14.45, P<.001).

CONCLUSION

Multidisciplinary monitoring, educational strategies, periodic foot examination for alterations, and early identification of risk factors are essential to prevent ulceration and reduce the disease burden.
