ABSTRACT This study examined the unadjusted and adjusted prevalence estimates of depression and anxiety at the state level and examined the odds ratios of depression and anxiety for selected risk behaviors, obesity, and chronic diseases.
The 2006 Behavioral Risk Factor Surveillance Survey, a random-digit-dialed telephone survey, collected depression and anxiety data from 217,379 participants in 38 states, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands. Current depressive symptoms were assessed with the standardized and validated eight-item Patient Health Questionnaire, and lifetime diagnosis of depression and anxiety was assessed by two additional questions (one question for each diagnosis).
The overall prevalence of current depressive symptoms was 8.7% (range by state and territory, 5.3%-13.7%); of a lifetime diagnosis of depression, 15.7% (range, 6.8%-21.3%); and of a lifetime diagnosis of anxiety, 11.3% (range, 5.4%-17.2%). After sociodemographic characteristics, adverse health behaviors, and chronic illnesses were adjusted for, cardiovascular disease, diabetes, asthma, smoking, and obesity were all significantly associated with current depressive symptoms, a lifetime diagnosis of anxiety, and a lifetime diagnosis of depression. Physically inactive adults were significantly more likely than those who were physically active to have current depressive symptoms or a lifetime diagnosis of depression, whereas those who drank heavily were significantly more likely than those who did not to have current depressive symptoms or a lifetime diagnosis of anxiety.
Depression and anxiety were strongly associated with common chronic medical disorders and adverse health behaviors. Examination of mental health should therefore be an integral component of overall health care.

    ABSTRACT: Overall, 13.7% of cancer survivors reported having current depression—higher than reported by adults without cancer (8.9%).•Women with reproductive cancer had 22% higher prevalence ratio for current depression than women without cancer.•Adults with gastrointestinal cancer and melanoma skin cancer had 53–58% higher prevalence ratio than adults without cancer.•Adults with type-unknown cancers had 41% higher prevalence ratio than adults without cancer.•Among cancer survivors, certain characteristics were differentially associated with risks of having current depression.

    ABSTRACT: Evidence shows that people feel mild positive moods when no strong emotional events are occurring, a phenomenon known as positive mood offset. We offer an evolutionary explanation of this characteristic, showing that it improves fertility, fecundity, and health, and abets other characteristics that were critical to reproductive success. We review research showing that positive mood offset is virtually universal in the nations of the world, even among people who live in extremely difficult circumstances. Positive moods increase the likelihood of the types of adaptive behaviors that likely characterized our Paleolithic ancestors, such as creativity, planning, mating, and sociality. Because of the ubiquity and apparent advantages of positive moods, it is a reasonable hypothesis that humans were selected for positivity offset in our evolutionary past. We outline additional evidence that is needed to help confirm that positive mood offset is an evolutionary adaptation in humans and we explore the research questions that the hypothesis generates.

    ABSTRACT: BACKGROUND: Type 2 diabetes and depression are commonly comorbid high-prevalence chronic disorders. Diet is a key diabetes risk factor and recent research has highlighted the relevance of diet as a possible risk for factor common mental disorders. This study aimed to investigate the interrelationship among dietary patterns, diabetes and depression. METHODS: Data were integrated from the National Health and Nutrition Examination Study (2009-2010) for adults aged 18+ (n=4588, Mean age=43yr). Depressive symptoms were measured by the Patient Health Questionnaire-9 and diabetes status determined via self-report, usage of diabetic medication and/or fasting glucose levels >/=126mg/dL and a glycated hemoglobin level >/=6.5% (48mmol/mol). A 24-h dietary recall interview was given to determine intakes. Multiple logistic regression was employed, with depression the outcome, and dietary patterns and diabetes the predictors. Covariates included gender, age, marital status, education, race, adult food insecurity level, ratio of family income to poverty, and serum C-reactive protein. RESULTS: Exploratory factor analysis revealed five dietary patterns (healthy; unhealthy; sweets; 'Mexican' style; breakfast) explaining 39.8% of the total variance. The healthy dietary pattern was associated with reduced odds of depression for those with diabetes (OR 0.68, 95% CI [0.52, 0.88], p=0.006) and those without diabetes (OR 0.79, 95% CI [0.64, 0.97], p=0.029) (interaction p=0.048). The relationship between the sweets dietary pattern and depression was fully explained by diabetes status. CONCLUSION: In this study, a healthy dietary pattern was associated with a reduced likelihood of depressive symptoms, especially for those with Type 2 diabetes.
