The effect of household crowding and composition on health in an Inuit cohort in Greenland.

Aims: This study aims to investigate the association between household crowding and household composition and self-rated health and mental health (GHQ scale) among the Inuit in Greenland. Poor housing conditions are a concern in Greenland, especially in the villages, where socioeconomic standards in general are lower. Methods: A cohort of 1282 adults participated in two population-based surveys in Greenland, the Inuit Health in Transition survey 2005-2010 (baseline) and The Health Survey in Greenland 2014 (follow-up). Associations between household conditions at baseline and health outcomes at follow-up (poor self-rated health and mental health measured by the GHQ scale) were examined using logistic regression models, adjusting for covariates at baseline. Results: Participants living in an overcrowded dwelling (more than one person per room) at baseline were more likely to report poor self-rated health at follow-up (OR 1.47; 95% CI 1.09; 1.99) compared with those not living in an overcrowded dwelling. In addition, participants who lived alone at baseline were more likely (OR 1.98; 95% CI 1.09; 3.58) to experience poor mental health at follow-up compared with those who lived with children. Conclusions: Results indicate that household conditions are related to health in Greenland. Public health authorities should work to ensure affordable housing of good quality in all communities.

Treatment delay and excessive substance use in bipolar disorder.

The aim of the present study was to investigate the relationship between treatment delay and excessive substance use. A total of 151 bipolar disorder (BD) I and II patients were consecutively recruited from in- and outpatient psychiatric units, and categorized as primary or secondary BD (without or with antecedent excessive substance use). Predictors of treatment delay among all patients, and predictors of subsequent excessive substance use among primary BD patients, were investigated with logistic regression analyses. The median treatment delay was 2.0 years (IQR 14.0). The risk of long treatment delays was increased in patients with BD II disorder, no lifetime psychosis, a higher age at first contact with specialized psychiatric services, primary BD, and excessive substance use. In primary BD, the risk for developing excessive substance use was increased in males, in patients with shorter education and longer treatment delays. Patients with antecedent excessive substance use had reduced risk of long treatment delays. The risk of developing excessive substance use after BD onset increased with longer treatment delays.
