A study on changes in weight and body mass index of patients post below knee amputation secondary to diabetes

Abstract

Introduction: The number of people with lower-limb amputations (LLA) is expected to double by the year 2050, largely because of vascular disease associated with an aging population and increased incidence of diabetes and heart disease. The change in weight pattern will help us in designing linear spring based osseointegrated prosthetics for people living in hilly areas with amputation who living in hilly terrain. Methodology: N were selected for the study. We used weights and heights obtained during inpatient and outpatient clinical encounters. N going under transtibial amputation were selected and the patients were categorized under two groups Type-1 and Type -2 diabetes. Height and B.M.I. was taken from the case record form at the time of entry of a patient in the general surgery department. Percent weight change, calculated as the difference between weight at time x and weight at baseline, divided by baseline weight x 100, was the primary outcome of interest. Results: Among 20 patients selected for the study (n=100). Out of which 6 patients were Type-1 diabetic and the rest 14 were type two diabetic. The height of twenty patients ranged from 154cm-174cm. with a mean height of 163.8cm. As expected based on our matching, the distribution of ages, BMI, reference years, and presence of a diabetes: 65 percent of individuals were between the ages of 25 and 74 yr, 73 percent had diabetes, and nine patient were overweight (range 25.5-29.9) where rest eleven patients were obese, out of which nine have B.M.I. 30-35 and rest two were above 35.1.The difference in change in weight between type one and type two patient were noted. Type one patient showed mean weight increase of 5055gm, where as type two diabetic showed an increase of 4894gm within the span of three months.
