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, BRFSSS pacific 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 . 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 . Obesity-related morbidity is estimated to account for 9.1% of total annual U.S. medical expenditures each year . Previous researches indicated that obesity might be significantly associated with depression [4,5]. Depression is one of the most prevalent mental disorders . The National Institute of Mental Health (NIMH) in 2000 estimated that 9.5% of the U.S. populations suffer from a depressive illness in any given year . The National Survey on Drug Use and Health (NSDUH) estimated that, during the years 2005-2006, 11.29% of total U.S. adults had experienced serious psychological distress in past year . 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 . It is reported that the relationship between depression and obesity is dependent upon different gender, age, and race/ ethnics. People younger than 65 years old are much more prone to get depressed than their counterparts . Besides, significant positive associations between depression and obesity are observed among women but not men [12,13,14]. However, when it comes to the relationship between depression and obesity dependent upon different races, there are some discrepancies. One report indicated that the Non-Hispanic Whites had a higher rate of depression compared to Non-Hispanic Blacks, Hispanics, and Asians . Another report observed that Hispanics are much more prone to get depressed than Whites and Blacks .
摘要：越來越多的超重和肥胖患病率是一個重要的公共衛生問題。美國成人人口當中，肥胖的患病率（定義為身體質量指數從30.0 KG/M2范圍99.8 KG/M2）從2000年的約20％上升到2008年的27％。以往的研究表明，肥胖可能會顯著地與抑郁癥有關。在美國和加拿大進行的一些研究表明肥胖和抑郁癥狀，心理困擾的措施，和抑郁癥病史的之間的關聯。然而，迄今的研究已進行了2006年的行為危險因素監測系統調查（BRFSS）的基礎上。會否研究參與者將是2006年行為風險因素監測系統（BRFSS）應答。被選為2006 BRFSS由于一個重大一套“健康日”的問題，隨著一些可選模塊和國有增值問題。從這項研究結果可以提供指示政府官員在社會政策決策，以幫助人們在需要心理健康服務。關鍵詞：肥胖，抑郁，警察總部，BRFSSS泰富致力日益增長的超重和肥胖的患病率是一個重要的公共衛生問題。美國成人人口當中，肥胖的患病率（定義為身體質量指數從30.0 KG/M2范圍99.8 KG/M2）從2000年的約20％上升到2008年的27％。肥胖可導致多種疾病的困擾，如糖尿病，高血壓，高膽固醇，哮喘，關節炎，健康狀況不佳。通常情況下，被認為超重或肥胖的患病率，由于能源失衡的后果，能量攝入超過能量消耗。據估計，每年在美國死亡人數280,000人歸因于肥胖或超重的。肥胖有關的發病率估計占美國每年的醫療總支出的9.1％，每年的。以往的研究表明，肥胖可能會顯著地與抑郁癥有關[4,5]。抑郁癥是最普遍的精神障礙之一。國立精神衛生研究所（NIMH）估計在2000年，美國人口的9.5％患有抑郁疾病，在任何給定的一年。全國藥物使用和健康調查（NSDUH），的估計，在2005-2006年期間，11.29％，占美國成年人經歷過嚴重的心理困擾，在過去的一年中。在美國和加拿大進行的一些研究表明肥胖和抑郁癥狀之間的關聯，心理困擾的措施，抑郁癥病史的。據悉，抑郁癥和肥胖癥之間的關系是依賴于不同的性別，年齡和種族/倫理。年齡小于65歲的人更容易獲得比他們的同行郁悶。此外，觀察到顯著的正相關，憂郁和肥胖之間的婦女，但不是男人[12,13,14]。然而，當它涉及到抑郁癥和肥胖癥之間的關系取決于不同的種族，也有一些差異。一份報告指出，非西班牙裔白人有較高的抑郁癥相比，非西班牙裔黑人，西班牙裔和亞裔。另一份報告指出，拉美裔比白人和黑人更容易產生郁悶。
