Type 2 diabetes mellitus is a complex metabolic disease that is associated with serious complications resulting in increased morbidity and mortality. The objective of the present study was to evaluate the effect of educational intervention on BMI of patients with type 2 diabetes mellitus.
Quasiexperimental pretest posttest control group design was adopted for the present study. The study was conducted among 140 patients with type 2 diabetes mellitus-70 in the experimental group and 70 in the control group-who attended the diabetic clinic, Medical College Hospital, Thiruvananthapuram. Samples were selected consecutively. Researcher collected data from the patients using a semi structured interview schedule and BMI was calculated by dividing the body weight in kilogram by the square of height in meter. The educational intervention was given to the patients in the experimental group at the diabetic clinic in small groups/individually and the patients in the control group received only the standard treatment. The effect of intervention was evaluated in the 3 rd month and 6th month.
The study showed that in the experimental group there was a reduction in the mean BMI from 24.60±3.14 kg/m2 to 24.22±3.16kg/m2 from base line to 6 months follow up, whereas there was an increase in mean BMI from 24.89±3.81kg/m2 to 25.41±3.82 kg/m2 in the control group. The effect of educational intervention on BMI in the experimental group with respect to control group was assessed by repeated measures ANOVA and found that it was statistically significant (p<0.0001). This study showed that educational intervention would significantly decrease the BMI among patients with type 2 diabetes mellitus.
We conclude that educational intervention was effective in decreasing the BMI in patients with type 2 diabetes mellitus.
