Abstract
INTRODUCTION: Serum proteins are an important indicator of the nutritional status in an individual. There is a worldwide prevalence of both undernourishment and obesity. It has been suggested that low Body Mass Index (BMI) is associated with a decrease in serum protein levels predisposing them to other illnesses. Overweight and obese individuals carry risk for various other non-communicable diseases. AIM: To compare the serum protein levels in underweight, overweight and obese individuals with that of normal body mass index individuals. MATERIALS AND METHODS: This prospective study was conducted in subjects who attended the master health checkup clinic of PSG hospitals. Subjects in the age group of 20-50 years were selected. Their serum proteins and BMI was measured. Twenty subjects each of underweight, normal, overweight and obese individuals were selected, categorized and compared. RESULTS: The serum protein level of normal individuals (Group I) was compared with underweight (Group II), overweight (Group III) and obese subjects (Group IV) by one-way ANOVA analysis. The mean serum total proteins in gm/dl in group I controls was 7.555±0.37 compared to Group II (underweight) which was 7.295±0.419. Low BMI was found to be associated with a decrease in serum protein level which was not statistically significant. Elevated BMI as in overweight and obese subjects showed no significant alterations in serum protein levels with p >0.05 and the changes were found to be independent of the body mass index. CONCLUSION: Underweight individuals showed a decrease in serum protein levels whereas there were no significant changes in the serum protein levels in overweight and obese individuals.
