Prevalence of diabetes among homeless and slum dwellers in Accra, Ghana: a survey study.

A total of 130 homeless and slum dwellers took part in the study out of which 7 (5.4%) participants were diagnosed with diabetes while 13 (10%) were considered as having prediabetes. This is slightly lower than what had been reported two decades ago but similar to overall estimates of diabetes prevalence in Africa (5.7%). Diagnosis of normoglycemia, prediabetes and diabetes was based on individual's hemoglobin A1c (HbA1c) level: ≤ 5.9%, 6.4-6.0%, and ≥ 6.5%, respectively. There was no significant association between prevalence of diabetes or prediabetes and the socio-demographic characteristics of the participants. The slightly lower diabetes prevalence among the homeless and slum dwellers compared to the general population may be due to constant movement of these people in the streets, a practice that could serve as a form of exercise for them. Intensive social support aimed at preventing and managing diabetes is crucial if we are to further reduce the incidence of diabetes in homeless people.
