Abstract
The growing prevalence of overweight and obesity is a major public health concern. Among the U.S. adult population, the prevalence of obesity (defined as a body mass index ranges from 30.0 kg/m2 to 99.8 kg/m2) increased from approximately 20% in 2000 to 27% in 2008. Previous researches indicated that obesity might be significantly associated with depression. Several researches conducted in the United States and Canada have indicated associations between obesity and depressive symptoms, measures of psychological distress, and history of depression. However, none of the studies to date has been conducted based on the 2006 Behavioral Risk Factor Surveillance System Survey (BRFSS). The propounded study participants will be 2006 Behavioral Risk Factor Surveillance System (BRFSS) responders. The 2006 BRFSS was chosen due to a significant set of “healthy days” questions along with some optional modules and state- added questions. Findings from this research can provide instructions to government officers on making social policy decisions to help people in need of mental health services.
Key words: obesity, depression, PHQ, BRFSS
Specific Aims
The growing prevalence of overweight and obesity is a major public health concern. Among the U.S. adult population, the prevalence of obesity (defined as a body mass index ranges from 30.0 kg/m2 to 99.8 kg/m2) increased from approximately 20% in 2000 to 27% in 2008 [1]. Obesity can lead to many kinds of disease problems, such as diabetes, high blood pressure, high cholesterol, asthma, arthritis and poor health status. Usually, the overweight or obesity prevalence is perceived due to the consequence of an energy imbalance, with energy intake exceeding that of energy expenditure. It is estimated that each year, among the U.S. death persons, 280,000 of whom are attributed to obesity or overweight [2]. Obesity-related morbidity is estimated to account for 9.1% of total annual U.S. medical expenditures each year [3].
