Background: Increasing prevalence of diabetes in India is resulting in an epidemiological transition. The care of the people with diabetes is traditionally seen as doctor centered, but the concept of selfâÂÂ€ÂÂ‘care of people with diabetes is a new domain and is proven beneficial. Aim: The aim was to determine the practice of selfâÂÂ€ÂÂ‘care activities among people with diabetes attending a tertiary care hospital in Mangalore. Subjects and Methods: A facilityâÂÂ€ÂÂ‘based crossâÂÂ€ÂÂ‘sectional study was conducted in Government Wenlock Hospital, Mangalore during September–October 2012. A total of 290 patients with >1âÂÂ€ÂÂ‘year duration of diabetes mellitus (DM) were asked to respond to summary diabetes selfâÂÂ€ÂÂ‘care activities questionnaire after obtaining the consent from them. The statistical analysis was performed in terms of descriptive statistics and association between the variables was tested using Mann–Whitney UâÂÂ€ÂÂ‘test. Results: A healthy eating plan on a daily basis was followed by 45.9% (133/290) of the participants, daily exercises for 30 min were followed by 43.4% (126/290), and regular blood sugar monitoring was done by 76.6% (222/290). Regarding the adherence to oral hypoglycemic agents and insulin, daily adherence to medication was seen among 60.5% (155/256) and 66.9% (138/206) were found to be adherent to insulin injections on a daily basis. Conclusions: SelfâÂÂ€ÂÂ‘care practices were found to be unsatisfactory in almost all aspects except for blood sugar monitoring and treatment adherence. As these practices are essential for prevention of complications and better qualityâÂÂ€ÂÂ‘of âÂÂ€ÂÂ‘life, more efforts should be put to educate the people with diabetes.
