Obesity is an increasing global problem. It has important implications, as it is associated with various life threatening diseases and metabolic disorders. Scientists at the Tel Aviv University have confirmed the long-held notion that sedentary lifestyle leads to obesity. Researchers said that the more time people spend sitting, the more fat they accumulate in the lower half of their bodies, or backside. According to the latest survey conducted by the Centers for Disease Control and Prevention, more than 35 percent of American adults and 17 percent of American children are considered obese. Obesity causes diabetes, heart disease, stroke, and certain types of cancer, placing a huge burden on health care systems and the economy. The medical condition is usually treated through a combination of diet, nutrition, exercise, and other techniques. The present study was initiated to estimate and compare the body composition of sedentary and nonsedentary working women. Most of the body composition studies are in males. Very few studies have been taken in female sedentary working women. We intended to study body composition parameters in sedentary working women and compare these parameters in women having nonsedentary life-style. Objective was to to calculate Body mass index [BMI], Body fat percentage and Waist-hip ratio [WHR] and to caregorise subjects according to classification and compare between groups. Body composition of sedentary working women (30) compared with nonsedentary working women (30). Obesity is an important indicator of health since it is significantly linked to morbidity and mortality. Our study clearly shows that prevalence of obesity is high in sedentary working women. Working women having sedentary life style need to undertake regular 30 minutes of moderate to vigours running, swimming, bicycling or 60 minutes of brisk walking exercise, to reduce or to prevent obesity and thereby preventing complications of obesity.
