Utilization of physician mental health services by birthing parents with young children during the COVID-19 pandemic: a population-based, repeated cross-sectional study.

BACKGROUND: The COVID-19 pandemic and nonpharmaceutical interventions that reduced the spread of infection had impacts on social interaction, schooling and employment. Concerns have been raised about the impact of these disruptions on the mental health of high-risk groups, including birthing parents of young children. METHODS: This population-based, repeated cross-sectional study used health administrative databases in Ontario, Canada, to link children to birth parents and to measure subsequent mental health visits of birthing parents of younger (age 0-5 yr) and school-aged (6-12 yr) children. We used a repeated cross-sectional study design to estimate expected rates for visits to physicians for mental health diagnoses, based on prepandemic trends (March 2016-February 2020), and to compare those to observed visit rates during the March 2020-November 2021 period of the pandemic. RESULTS: We identified 2 cohorts: 986 870 birthing parents of younger children and 1 012 997 birthing parents of school-aged children. In both cohorts, observed visit rates were higher than expected in the June 2020-August 2020 quarter (incidence rate ratio [IRR] 1.13, 95% confidence interval [CI] 1.10-1.16; and IRR 1.10, 95% CI 1.07-1.13, respectively), peaked in December 2020-February 2021 (IRR 1.24, 95% CI 1.20-1.27; and IRR 1.20, 95% CI 1.16-1.23) and remained higher than expected in September 2021-November 2021 (IRR 1.12, 95% CI 1.08-1.16; and IRR 1.09, 95% CI 1.06-1.13). The increases were driven mostly by visits for mood and anxiety disorders, and trends in increases were similar across physician type, birthing-parent age and deprivation quintile. INTERPRETATION: The COVID-19 pandemic was associated with increased mental health visits for parents of young children. This raises concerns about mental health impacts and highlights the need to address these concerns.

Sex differences among children, adolescents and young adults for mental health service use within inpatient and outpatient settings, before and during the COVID-19 pandemic: a population-based study in Ontario, Canada.

OBJECTIVES: The pandemic and public health response to contain the virus had impacts on many aspects of young people's lives including disruptions to daily routines, opportunities for social, academic, recreational engagement and early employment. Consequently, children, adolescents and young adults may have experienced mental health challenges that required use of mental health services. This study compared rates of use for inpatient and outpatient mental health services during the pandemic to pre-pandemic rates. DESIGN: Population-based repeated cross-sectional study. SETTING: Publicly delivered mental healthcare in primary and secondary settings within the province of Ontario, Canada. PARTICIPANTS: All children 6-12 years of age (n=2 043 977), adolescents 13-17 years (n=1 708 754) and young adults 18-24 years (n=2 286 544), living in Ontario and eligible for provincial health insurance between March 2016 and November 2021. PRIMARY OUTCOME MEASURES: Outpatient mental health visits to family physicians and psychiatrists for: mood and anxiety disorders, alcohol and substance abuse disorders, other non-psychotic mental health disorders and social problems. Inpatient mental health visits to emergency departments and hospitalisations for: substance-related and addictive disorders, anxiety disorders, assault-related injuries, deliberate self-harm and eating disorders. All outcomes were analysed by cohort and sex. RESULTS: During the pandemic, observed outpatient visit rates were higher among young adults by 19.01% (95% CI: 15.56% to 22.37%; 209 vs 175 per 1000) and adolescent women 24.17% (95% CI: 18.93% to 29.15%; 131 vs 105 per 1000) for mood and anxiety disorders and remained higher than expected. Female adolescents had higher than expected usage of inpatient care for deliberate self-harm, eating disorders and assault-related injuries. CONCLUSIONS: Study results raise concerns over prolonged high rates of mental health use during the pandemic, particularly in female adolescents and young women, and highlights the need to better monitor and identify mental health outcomes associated with COVID-19 containment measures and to develop policies to address these concerns.

Higher Neighborhood Drivability Is Associated With a Higher Diabetes Risk in Younger Adults: A Population-Based Cohort Study in Toronto, Canada.

OBJECTIVE: Car dependency contributes to physical inactivity and, consequently, may increase the likelihood of diabetes. We investigated whether neighborhoods that are highly conducive to driving confer a greater risk of developing diabetes and, if so, whether this differs by age. RESEARCH DESIGN AND METHODS: We used administrative health care data to identify all working-age Canadian adults (20-64 years) who were living in Toronto on 1 April 2011 without diabetes (type 1 or 2). Neighborhood drivability scores were assigned using a novel, validated index that predicts driving patterns based on built environment features divided into quintiles. Cox regression was used to examine the association between neighborhood drivability and 7-year risk of diabetes onset, overall and by age-group, adjusting for baseline characteristics and comorbidities. RESULTS: Overall, there were 1,473,994 adults in the cohort (mean age 40.9 ± 12.2 years), among whom 77,835 developed diabetes during follow-up. Those living in the most drivable neighborhoods (quintile 5) had a 41% higher risk of developing diabetes compared with those in the least drivable neighborhoods (adjusted hazard ratio 1.41, 95% CI 1.37-1.44), with the strongest associations in younger adults aged 20-34 years (1.57, 95% CI 1.47-1.68, P < 0.001 for interaction). The same comparison in older adults (55-64 years) yielded smaller differences (1.31, 95% CI 1.26-1.36). Associations appeared to be strongest in middle-income neighborhoods for younger residents (middle income 1.96, 95% CI 1.64-2.33) and older residents (1.46, 95% CI 1.32-1.62). CONCLUSIONS: High neighborhood drivability is a risk factor for diabetes, particularly in younger adults. This finding has important implications for future urban design policies.

Impact of the COVID-19 Pandemic on Diabetes Care for Adults With Type 2 Diabetes in Ontario, Canada.

OBJECTIVES: The COVID-19 pandemic and related public health prevention measures have led to a disruption of the delivery of routine care and may have had an impact on the quality of diabetes care. Our aim in this study was to evaluate the extent to which structure, process and outcome quality measures in diabetes care changed in the first 6 months of the pandemic compared with previous periods. METHODS: A before-and-after observational study of all community-living Ontario residents >20 years of age and living with diabetes. The patients were divided into 3 cohorts: a pandemic cohort, alive March to September 2020 (n=1,393,404); reference cohort 1, alive March to September 2019 (n=1,415,490); and reference cohort 2, alive September 2019 to February 2020 (n=1,444,000). Outcome measures were in-person/virtual visits to general practitioners and specialists, eye examinations, glycated hemoglobin (A1C) and low-density lipoprotein (LDL) testing, filled prescriptions, and admissions to emergency departments (EDs) and hospitals for acute and chronic diabetes complications. RESULTS: The probability of an in-person visit to a GP decreasing by 47% (95% confidence interval [CI], 47% to 47%) in the pandemic period compared with both previous periods. The probability of having an eye exam was lower by 43% (95% CI, 44% to 43%), an A1C test by 28% (95% CI, 29% to 28%) and an LDL test by 31% (95% CI, 31% to 31%) in the pandemic period compared with the same 6-month period the year before. There were very small decreases in drug prescriptions and decreases of 18% and 16% in ED and hospital visits for complications. CONCLUSIONS: We observed disruptions to both structure and processes measures of diabetes care in Ontario during the first wave of the pandemic.

Development of a neighborhood drivability index and its association with transportation behavior in Toronto.

BACKGROUND: Car driving is a form of passive transport that is associated with an increase in physical inactivity, obesity, air pollution and noise. Built environment characteristics may influence transport mode choice, but comprehensive indices for built environment characteristics that drive car use are still lacking, while such an index could provide tangible policy entry points. OBJECTIVE: We developed and validated a neighbourhood drivability index, capturing combined dimensions of the neighbourhood environment in the City of Toronto, and investigated its association with transportation choices (car, public transit or active transport), overall, by trip length, and combined for residential neighbourhood and workplace drivability. METHODS: We used exploratory factor analysis to derive distinct factors (clusters of one or more environmental characteristics) that reflect the degree of car dependency in each neighbourhood, drawing from candidate variables that capture density, diversity, design, destination accessibility, distance to transit, and demand management. Area-level factor scores were then combined into a single composite score, reflecting neighbourhood drivability. Negative binomial generalized estimating equations were used to test the association between driveability quintiles (Q) and primary travel mode (>50% of trips by car, public transit, or walking/cycling) in a population-based sample of 63,766 Toronto residents enrolled in the Transportation Tomorrow Survey (TTS) wave 2016, adjusting for individual and household characteristics, and accounting for clustering of respondents within households. RESULTS: The drivability index consisted of three factors: Urban sprawl, pedestrian facilities and parking availability. Relative to those living in the least drivable neighbourhoods (Q1), those in high drivability areas (Q5) had a significantly higher rate of car travel (adjusted Risk Ratio (RR): 1.80, 95%CI: 1.77-1.88), and lower rate of public transit use (RR: 0.90, 95%CI: 0.85-0.94) and walking/cycling (RR: 0.22, 95%CI: 0.19-0.25). Associations were strongest for short trips (<3 km) (RR: 2.72, 95%CI: 2.48-2.92), and in analyses where both residential and workplace drivability was considered (RR for car use in high/high vs. low/low residential/workplace drivability: 2.18, 95%CI: 2.08-2.29). CONCLUSION: This novel neighbourhood drivability index predicted whether local residents drive or use active modes of transportation and can be used to investigate the association between drivability, physical activity, and chronic disease risk.

Examine the association between key determinants identified by the chronic disease indicator framework and multimorbidity by rural and urban settings.

BACKGROUND: Multimorbidity, often defined as having two or more chronic conditions is a global phenomenon. This study examined the association between key determinants identified by the chronic disease indicator framework and multimorbidity by rural and urban settings. The prevalence of individual diseases was also investigated by age and sex. METHODS: The Canada Community Health Survey and linked health administrative databases were used to examine the association between multimorbidity, sociodemographic, behavioral, and other risk factors in the province of Ontario. A multivariable logistic regression model was used to conduct the main analysis. RESULTS: Analyses were stratified by age (20-64 and 65-95) and area of residence (rural and urban). A total sample of n = 174,938 residents between the ages of 20-95 were examined in the Ontario province, of which 18.2% (n = 31,896) were multimorbid with 2 chronic conditions, and 23.4% (n = 40,883) with 3+ chronic conditions. Females had a higher prevalence of 2 conditions (17.9% versus 14.6%) and 3+ conditions (19.7% vs. 15.6%) relative to males. Out of all examined variables, poor self-perception of health, age, Body Mass Index, and income were most significantly associated with multimorbidity. Smoking was a significant risk factor in urban settings but not rural, while drinking was significant in rural and not urban settings. Income inequality was associated with multimorbidity with greater magnitude in rural areas. Prevalence of multimorbidity and having three or more chronic conditions were highest among low-income populations. CONCLUSION: Interventions targeting population weight, age/sex specific disease burdens, and additional focus on stable income are encouraged.
