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 [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]. Previous researches indicated that obesity might be significantly associated with depression [4,5]. Depression is one of the most prevalent mental disorders [6]. 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 [7]. 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 [8]. Several researches conducted in the United States and Canada have indicated associations between obesity and depressive symptoms [9], measures of psychological distress [10], and history of depression [11]. 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 [9]. 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 [15]. Another report observed that Hispanics are much more prone to get depressed than Whites and Blacks [9].
摘要：越来越多的超重和肥胖患病率是一个重要的公共卫生问题。美国成人人口当中，肥胖的患病率（定义为身体质量指数从30.0 KG/M2范围99.8 KG/M2）从2000年的约20％上升到2008年的27％。以往的研究表明，肥胖可能会显着地与抑郁症有关。在美国和加拿大进行的一些研究表明肥胖和抑郁症状，心理困扰的措施，和抑郁症病史的之间的关联。然而，迄今的研究已进行了2006年的行为危险因素监测系统调查（BRFSS）的基础上。会否研究参与者将是2006年行为风险因素监测系统（BRFSS）应答。被选为2006 BRFSS由于一个重大一套“健康日”的问题，随着一些可选模块和国有增值问题。从这项研究结果可以提供指示政府官员在社会政策决策，以帮助人们在需要心理健康服务。关键词：肥胖，抑郁，警察总部，BRFSSS泰富致力日益增长的超重和肥胖的患病率是一个重要的公共卫生问题。美国成人人口当中，肥胖的患病率（定义为身体质量指数从30.0 KG/M2范围99.8 KG/M2）从2000年的约20％上升到2008年的27％[1]。肥胖可导致多种疾病的困扰，如糖尿病，高血压，高胆固醇，哮喘，关节炎，健康状况不佳。通常情况下，被认为超重或肥胖的患病率，由于能源失衡的后果，能量摄入超过能量消耗。据估计，每年在美国死亡人数280,000人归因于肥胖或超重的[2]。肥胖有关的发病率估计占美国每年的医疗总支出的9.1％，每年的[3]。以往的研究表明，肥胖可能会显着地与抑郁症有关[4,5]。抑郁症是最普遍的精神障碍之一[6]。国立精神卫生研究所（NIMH）估计在2000年，美国人口的9.5％患有抑郁疾病，在任何给定的一年[7]。全国药物使用和健康调查（NSDUH），的估计，在2005-2006年期间，11.29％，占美国成年人经历过严重的心理困扰，在过去的一年中[8]。在美国和加拿大进行的一些研究表明肥胖和抑郁症状之间的关联[9]，心理困扰的措施[10]，抑郁症病史的[11]。据悉，抑郁症和肥胖症之间的关系是依赖于不同的性别，年龄和种族/伦理。年龄小于65岁的人更容易获得比他们的同行郁闷[9]。此外，观察到显着的正相关，忧郁和肥胖之间的妇女，但不是男人[12,13,14]。然而，当它涉及到抑郁症和肥胖症之间的关系取决于不同的种族，也有一些差异。一份报告指出，非西班牙裔白人有较高的抑郁症相比，非西班牙裔黑人，西班牙裔和亚裔[15]。另一份报告指出，拉美裔比白人和黑人[9]更容易产生郁闷。
