Abstract: Background: Previous work has suggested significant associations between various psychological symptoms (e.g., depression, anxiety, anger, alcohol abuse) and hypertension. However, the presence and extent of associations between common mental disorders and subsequent adult onset of hypertension remain unclear.
Importance Bipolar disorder is associated with premature mortality, but the specific causes and underlying pathways are unclear. Objective To examine the physical health effects of bipolar disorder using outpatient and inpatient data for a national population.
Importance Long-term longitudinal studies are needed to delineate the trajectory of depressive symptoms across adulthood and to individuate factors that may contribute to increases in depressive symptoms in older adulthood. Objectives To estimate the trajectory of depressive symptoms across the adult life span; to test whether this trajectory varies by demographic factors (sex, ethnicity, and educational level) and antidepressant medication use; and to test whether disease burden, functional limitations, and proximity to death explain the increase in depressive symptoms in old age. Design Longitudinal study
Abstract: Objective: This study examined if associations between body mass index (BMI) and mental and physical health were independent of genetic and familial factors.Method: Data from 2831 twins (66% female) were used in an epidemiological co-twin control design with measures of BMI and mental and physical health outcomes. Generalized estimating equation regressions assessed relationships between BMI and health outcomes controlling for interdependency among twins and demographics. Within-pair regression analyses examined the association of BMI with health outcomes controlling for genetic and familial influences.Results: Adjusted analyses with individual twins found associations in women between BMI and perceived stress (P=.01) and depression (P=.002), and the link between BMI and depression (P=.03) was significant in men
Abstract: Objective: This study sought to examine the prevalence of skin picking disorder (SPD) in a university sample and assess associated physical and mental health correlates.Methods: A 54-item anonymous, voluntary survey was distributed via random email generation to a sample of 6000 university students. Current psychological and physical status was assessed, along with academic performance. Positive screens for SPD were determined based upon individuals meeting full proposed DSM-V criteria.Results: A total of 1916 participants (31.9%; mean age 22.7±5.1; 58.1% female) responded and were included in the analysis.
