Republihsed article: Oxidative Stress in Relation to Obesity Indices in Gujarati and Non-Gujarati Young Girls Before and After Fiber Diet

Abstract

The global epidemic of obesity has alarmed all and is also becoming an increasing problem in many developing countries. The current dietetic practice is to recommend a healthy eating plan of reduced fat, and increased fiber intake1. Oxidative stress plays a crucial role in this process by lipid Peroxidation. The present study emphasizes on an anthropometric study and clinical study with maize diet in 1001 Gujarati and non-Gujarati girls, aged between 18-30 years. The study was divided into two parts. The first part comprised of classifying and distributing the total girls into two groups, Gujarati and non-Gujarati groups to find out the prevalence of girls according to various subgroups or categories. Out of the 1001 girls, 526 girls were Gujaratis and 475 girls were non-Gujaratis. In the second part of the study the girls were examined for oxidative stress, before and after maize diet. The parameters selected to evaluate oxidative stress were malondialdehyde, an oxidative stress marker; along with the statistical evaluation of the parameter. Normal weight girls had low MDA. Parameter for all three weight ranges was highly significant when matched for maize diet. As far as the effect of maize diet is concerned all four groups of body mass index showed almost similar results in the form of highly significant parameter (P < 0.001). MDA was significantly changed in normal and overweight groups. MDA in all three categories changed significantly after the maize diet (P < 0.001), When a comparison of Gujarati and non-Gujarati was done according to waist hip ratio categories it was significant for the obese category. Subjects with high waist circumference, waist hip ratio, body mass index > 25 kg/m2 showed quite high values of MDA, when compared to subjects with a normal waist circumference, waist hip ratio and body mass index < 25 kg/m2. Mean values of MDA, for overweight and normal weight categories were 3.22 ± 0.18 nmol/ml v/s 1.64 ± 0.35 nmol/ml, However, the dietary effect of maize was highly significant in all categories of indices (P < 0.001). Two categories of body fat percent < 33% and > 33% and two categories of total body fat < 20 kg and > 20 kg were made, and effect of maize diet was almost found to be equal on it for all categories with statistically significant parameter.
