Housing as a determinant of Inuit mental health: associations between improved housing measures and decline in psychological distress after rehousing in Nunavut and Nunavik.

ABSTRACT: In 2014-2015, more than 400 public housing units were constructed in Nunavut and Nunavik, two of the four Inuit regions in Canada. This provided the opportunity to assess the impact of improved housing conditions from a population health perspective in 12 Inuit communities where housing needs were the most severe. The aim of the research is to examine the associations between changes in housing conditions and changes in psychological distress pre-post rehousing. A pre-post uncontrolled study was conducted in collaboration with Nunavut- and Nunavik-based organizations. Applicants at the top of public housing waitlists were recruited by local housing officers; participants completed questionnaires 1-6 months before rehousing, and 15-18 months after. Change in psychological distress was measured with the Kessler 6-item scale. Changes in three housing measures were examined: number of adults per household, number of children per household, and sense of home score. For each housing measure, a categorical variable stratified participants into three categories. The reference category included participants reporting significant change in the concerned housing measure; the two other categories included participants reporting little or no change. Associations were tested with linear multilevel regression models for change. A total of 102 Inuit adults completed the study. A reduction in the number of adults per household (living with 2 adults or less after rehousing) and an increase in sense of home were associated with significant decline in psychological distress pre-post rehousing (p < 0.001). Increased investments leading to such improvements in housing circumstances are promising ways to promote mental health in Inuit regions.

Project description:BackgroundInuit children from Nunavut have been observed to have high rates of macrocephaly, which sometimes leads to burdensome travel for medical evaluation, often with no pathology identified upon assessment. Given reports that World Health Organization (WHO) growth charts may not reflect all populations, we sought to compare head circumference measurements in a cohort of Inuit children with the WHO charts.MethodsWe extracted head circumference data from a previous retrospective cohort study where, with Inuit partnership, we reviewed medical records of Inuit children (from birth to age 5 yr) born between Jan. 1, 2010, and Dec. 31, 2013, and residing in Nunavut. To create a cohort of Inuit children similar to the cohorts used in the development of the WHO growth charts, we excluded children with preterm birth, documented neurologic or genetic disease, and most congenital anomalies. We compared head circumference values with the 2007 WHO charts using centiles estimated with a generalized additive model.ResultsWe analyzed records of 1960 Inuit children (8866 data points), of whom 993 (50.8%) were female. Most data were from ages 0 to 36 months. At all age points, we found that the study cohort had statistically significantly larger head circumferences than WHO medians, with most z scores for head circumference measurements among Inuit children falling 0.5-1 standard deviations above the WHO reference (p < 0.001). At age 12 months, median head circumferences were 1.3 cm and 1.5 cm larger for male and female Inuit children, respectively. Using WHO growth curves, macrocephaly was significantly overdiagnosed and microcephaly was underdiagnosed (p < 0.001).InterpretationOur results support the observation that Inuit children from Nunavut have larger head circumferences than other populations, and use of the WHO charts may thus lead to overdiagnosis of macrocephaly and underdiagnosis of microcephaly. Population-specific growth curves for Inuit children should be considered to provide timely and appropriate diagnoses of microcephaly and avoid overinvestigation of macrocephaly.

Project description:BackgroundStructural aspects of health care systems, such as limited access to specialized surgical and perioperative care, can negatively affect the outcomes and resource use of patients undergoing elective and emergency surgical procedures. The aim of this study was to compare postoperative outcomes of Nunavut Inuit and non-Inuit patients at a Canadian quaternary care centre.MethodsWe conducted a retrospective cohort study involving adult (age ≥ 18 yr) patients undergoing inpatient surgery from 2011 to 2018 at The Ottawa Hospital, the quaternary referral hospital for the Qikiqtaaluk Region of Nunavut. The study was designed and conducted in collaboration with Nunavut Tunngavik Incorporated. The primary outcome was a composite of in-hospital death or complications.Secondary outcomes included postoperative length of stay in hospital, adverse discharge disposition, readmissions within 30 days and total hospitalization costs.ResultsA total of 98 701 episodes of inpatient surgical care occurred among patients aged 18 to 104 years; 928 (0.9%) of these involved Nunavut Inuit, and 97 773 involved non-Inuit patients. Death or postoperative complication occurred more often among Nunavut Inuit than non-Inuit patients (159 [17.2%] v. 15 691 [16.1%]), which was significantly different after adjustment for age, sex, surgical specialty, risk and urgency (odds ratio [OR] 1.25, 95% confidence interval [CI] 1.03-1.51). This association was most pronounced in cases of cancer (OR 1.63, 95% CI 1.03-2.58) and elective surgery (OR 1.58, 95% CI 1.20-2.10). Adjusted rates of readmission, adverse discharge disposition, length of stay and total costs were significantly higher for Nunavut Inuit.InterpretationNunavut Inuit had a 25% relative increase in their odds of morbidity and death after surgery at a major quaternary care hospital in Canada compared with non-Inuit patients, while also having higher rates of other adverse outcomes and resource use. An examination of perioperative systems involving patients, Inuit leadership, health care providers and governments is required to address these differences in health outcomes.
