The Correlation Between Obesity, Depression, and Physical Activity
Obesity is becoming an impending epidemic in our society (Hill, Wyatt, Reed, & Peters, 2003; Kottke, Wu, & Hoffman, 2003). Prevalence of obesity is on the rise and deaths attributable to it are higher than ever. It is estimated by the NIDDK (2003) that 30.5% of adults in the United States are obese and if the rate of increase remains constant, 39% of adults will be obese by the year 2008 (Hill, et al. 2003). In a study conducted by Thorpe, et al. (2004) out of 2681 New York elementary school students 24% were obese, so there is a high prevalence in children as well. Flegal, Williamson, Pamuk, and Rosenberg (2004) discovered that the obese population contributes ten times more deaths per year, about 300,000, than the portion of the country within normal weight categories.
The cost of lives is not the only payment for obesity, the nation suffers economically as well by paying more for health care (Kottke, et al. 2003). Obese medical patients have many more risks associated with medical care (NIDDK, 2003; Neville, Brown, Weng, Demetriades, & Velmahos, 2004). A higher rate of multiple organ failure is prevalent in the obese which often leads to death (Neville, et al. 2004). This means that obese patients need to be monitored more closely, which effectively costs more (Neville, et al. 2004). There are also indirect costs of obesity due to lost jobs by individuals who are disabled by their condition (Kottke, et al. 2003). Overall, the yearly cost due to obesity is estimated to be 117 billion dollars (NIDDK, 2003). The words obesity and overweight can have a broad meaning. Scientists and physicians, however, have designated a small number of accepted systems associated with body mass index, or BMI. BMI is a measurement of height versus weight, and appears in the units kg/m^2 (Ariza, Greenberg, & Unger, 2004; NIDDK, 2003). Most research is done with the guidelines being a BMI of 25 to 29.9 is considered overweight, and a BMI greater than 30 is considered obese.
