RESUMEN
BACKGROUND: Research on the impact of the COVID-19 pandemic on mothers/childbearing parents has mainly been cross-sectional and focused on psychological symptoms. This study examined the impact on function using ongoing, systematic screening of a representative Ontario sample. METHODS: An interrupted time series analysis of repeated cross-sectional data from a province-wide screening program using the Healthy Babies Healthy Children (HBHC) tool assessed changes associated with the pandemic at the time of postpartum discharge from hospital. Postal codes were used to link to neighborhood-level data. The ability to parent or care for the baby/child and other psychosocial and behavioral outcomes were assessed. RESULTS: The co-primary outcomes of inability to parent or care for the baby/child were infrequently observed in the pre-pandemic (March 9, 2019-March 15, 2020) and initial pandemic periods (March 16, 2020-March 23, 2021) (parent 209/63,006 (0.33%)-177/56,117 (0.32%), care 537/62,955 (0.85%)-324/56,086 (0.58%)). Changes after pandemic onset were not observed for either outcome although a significant (p = 0.02) increase in slope was observed for inability to parent (with questionable clinical significance). For secondary outcomes, worsening was only seen for reported complications during labor/delivery. Significant improvements were observed in the likelihood of being unable to identify a support person to assist with care, need of newcomer support, and concerns about money over time. CONCLUSIONS: There were no substantive changes in concerns about ability to parent or care for children. Adverse impacts of the pandemic may have been mitigated by accommodations for remote work and social safety net policies.
RESUMEN
PURPOSE: People with learning disabilities have complex challenges and needs that differ from people without these conditions. Accessing needed health and mental health care may be affected by level of independence and severity of learning challenges. Our study examined factors and associations which impact help seeking and satisfaction with mental health care in a Canadian nationally representative sample. METHODS: Logistic regression and multinomial logistic regression was used to analyze the 2012 Canadian Community Health Survey- Mental Health (CCHS 2012) cross-sectional survey. We investigated the odds of distressed individuals (1) perceiving a need for mental health care, (2) seeking out professional mental health care, and (3) if their needs were met by mental health services. The presence of a learning disability was assessed as a moderator variable in all models. RESULTS: Distressed adults with learning disabilities did not perceive a need for mental health care as often as distressed adults without a learning disability (OR = 3.82;95%CI:1.64,8.93 vs. OR = 12.00;95%CI:9.19,15.67). Distressed adults with a learning disability weren't as likely to seek out mental health services, but were more satisfied with the mental health care they received as compared to adults without a learning disability. CONCLUSION: The findings suggest that adults with learning disabilities have unmet needs. They are less likely to perceive a need for treatment, or to seek treatment, when they are distressed. Future investigation is necessary to understand the factors that influence perceived need and treatment seeking in this under-served population.
RESUMEN
PURPOSE: Migrants may have elevated exposure to stressors, which can affect their physical and mental well-being. However, migrants often experience a healthy immigrant effect, the applicability of this phenomena to eating disorders is unknown. We aimed to synthesize the available literature and estimate a summary measure of prevalence odds ratio for eating disorders in migrant populations compared to local populations. METHODS: A literature search was conducted using MEDLINE, Embase, PsycINFO, and Web of Science with keywords on migration and eating disorders. Inclusion criteria involved using a validated eating disorder scale and having a comparator group. Two independent reviewers performed study screening and data extraction. The NIH Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies was used to assess risk of bias. Random-effects models of meta-analysis were applied to compare eating disorder prevalence between migrants and local populations. RESULTS: There were 10 studies included in our review (meta-analysis = 6, narrative synthesis = 4). Studies provided prevalence estimates for: any eating disorder, binge eating disorder, anorexia nervosa, and bulimia nervosa. Among studies with a diagnostic instrument, the pooled prevalence odds ratio (POR) between migrants and local populations for any eating disorder was 0.45 (95%CI: 0.35-0.59). However, a subgroup analysis of eating disorder instruments among studies using risk assessment tools demonstrated inconsistent findings, with both increases and decreases in prevalence. CONCLUSION: Migrants were found to have a lower prevalence of eating disorders compared to local populations, supporting the healthy immigrant hypothesis. However, this effect differs between diagnostic and risk assessment tools.

BACKGROUND: Few studies have examined how parenting influences the associations between prenatal maternal stress and children's mental health. The objectives of this study were to examine the sex-specific associations between prenatal maternal stress and child internalizing and externalizing symptoms, and to assess the moderating effects of parenting behaviors on these associations. METHODS: This study is based on 15 963 mother-child dyads from the Norwegian Mother, Father, and Child Cohort Study (MoBa). A broad measure of prenatal maternal stress was constructed using 41 self-reported items measured during pregnancy. Three parenting behaviors (positive parenting, inconsistent discipline, and positive involvement) were assessed by maternal report at child age 5 years. Child symptoms of internalizing and externalizing disorders (depression, anxiety, attention-deficit hyperactivity disorder, conduct disorder, and oppositional-defiant disorder) were assessed by maternal report at age 8. Analyses were conducted using structural equation modeling techniques. RESULTS: Prenatal maternal stress was associated with child internalizing and externalizing symptoms at age 8; associations with externalizing symptoms differed by sex. Associations between prenatal maternal stress and child depression, and conduct disorder and oppositional-defiant disorder in males, became stronger as levels of inconsistent discipline increased. Associations between prenatal maternal stress and symptoms of attention-deficit hyperactivity disorder in females were attenuated as levels of parental involvement increased. CONCLUSIONS: This study confirms associations between prenatal maternal stress and children's mental health outcomes, and demonstrates that these associations may be modified by parenting behaviors. Parenting may represent an important intervention target for improving mental health outcomes in children exposed to prenatal stress.

BACKGROUND: Maternal immune activation is a potential mechanism underlying associations between maternal stress during pregnancy and offspring mental health problems. This study examined associations between prenatal maternal stress, maternal inflammation during pregnancy, and children's internalizing and externalizing symptoms from 3 to 10 years of age, and whether maternal inflammation mediated the associations between prenatal maternal stress and children's internalizing and externalizing symptoms. METHODS: This study comprised 4,902 mother-child dyads in the Generation R study. Prenatal maternal stress was assessed using self-reported data collected during pregnancy and analyzed as a latent variable consisting of four stress domains. Maternal inflammation during pregnancy was assessed using serum concentrations of C-reactive protein (CRP) measured at a median of 13.5 weeks' gestation. Child internalizing and externalizing symptoms were assessed using the Child Behavior Checklist (CBCL) by maternal report at ages 3 years, 5 years, and 10 years; paternal-reported CBCL data were also available at 3 years and 10 years. RESULTS: Prenatal maternal stress was associated with maternal-reported internalizing and externalizing symptoms of the child at 3, 5, and 10 years of age, and with paternal-reported internalizing and externalizing symptoms at 3 and 10 years. Prenatal maternal stress was associated with maternal CRP concentrations prior to, but not after, covariate adjustment. Maternal CRP concentrations during pregnancy were associated with paternal-reported internalizing symptoms of offspring at 10 years of age prior to, but not after, covariate adjustment. There was no evidence that CRP concentrations mediated the associations between prenatal maternal stress and children's internalizing or externalizing symptoms. CONCLUSIONS: Maternal stress during pregnancy is associated with higher levels of internalizing and externalizing symptoms in children, but this association is not because of differences in maternal immune activation linked to maternal stress. Replication of these findings in other cohorts is required; examination of other biomarkers or variation in immune activity during pregnancy would also benefit from further exploration.

INTRODUCTION: Worldwide, approximately 1900 people die by suicide daily. Daily elevations in air pollution and temperature have previously been linked to a higher risk of death from suicide. To date, there have been relatively few studies of air pollution and suicide, particularly at a national level. National analyses play an important role in shaping health policy to mitigate against adverse health outcomes. METHODS: We used a time-stratified case-crossover study design to investigate the influence of short-term (i.e., day to day) interquartile range (IQR) increases in air pollutants (nitrogen dioxide [NO2], ozone [O3], and fine particulate matter [PM2.5]) and temperature on suicide mortality in Canada between 2002 and 2015. For air pollution models, odds ratios (ORs) derived from conditional logistic regression models were adjusted for average daily temperature, and holidays. For temperature models, ORs were adjusted for holidays. Stratified analyses were undertaken by suicide type (non-violent and violent), sex, age, and season. RESULTS: Analyses are based on 50,800 suicide deaths. Overall, temperature effects were stronger than those for air pollution. A same day IQR increase in temperature (9.6 °C) was associated with a 10.1% increase (95% confidence interval (CI): 9.0%-11.2%) of death from suicide. For 3-day average increase of O3 (IQR = 14.1 ppb), PM2.5 (IQR = 5.6 µg/m3) and NO2 (IQR = 9.7 ppb) the corresponding risks were 4.7% (95% CI: 3.9, 5.6), 3.4% (95% CI: 3.0, 3.8), and 2.0% (95% CI: 1.1, 2.8), respectively. All pollutants showed stronger associations with suicide during the warmer season (April-September). Stratified analyses revealed stronger associations for both temperature and air pollution in women. CONCLUSIONS: Daily increases in air pollution and temperature were found to increase the risk of death from suicide. Females, particularly during warmer season, were most vulnerable to these exposures. Policy decisions related to air pollution and climate change should consider effects on mental health.

PURPOSE: The non-medical use of prescription medications among adolescents has become a concerning public health issue. This study assessed the prevalence of the non-medical use of prescription medications in Ontario high school students, and explored the moderating effect of this use on the relationship between psychological distress and unmet mental health needs. METHODS: Cross-sectional data for 4896 students, age 14-18, were drawn from the 2019 Ontario Student Drug Use and Health Survey. Psychological distress was measured using the Kessler-6 Distress Scale, unmet mental health needs were defined by self-report (yes/no), and non-prescription medication use was defined by self-reported frequency of use. Using logistic regression, we explored the effect of the non-medical use of prescription medications on the relationship between psychological distress and unmet mental health needs. RESULTS: High proportions of Ontario students reported serious psychological distress (22%), some degree of unmet mental health need (38%), and/or non-medical use of prescription medications (13%). While there were strong associations between psychological distress and unmet mental health need, this association was weaker among those reporting non-medical use of prescription medications (OR = 3.3, 95% CI 1.9-5.7) compared to non-users (OR = 5.6, 95% CI 4.5-7.1). CONCLUSION: Our findings suggest that Ontario students experiencing distress and using non-prescribed medications are less likely to identify a need for mental health support, highlighting the consequences of apparent self-medication through misuse of prescription medications. To assist in the redirection of adolescent perceptions of healthy coping strategies, population-based educational programming, with targeted promotion of both formal and informal mental health care resources, should be considered.

Positive maternal mental health can improve perceptions of stressful situations and promote the use of adaptive coping strategies. However, few studies have examined how positive maternal mental health affects children's development. The aims of this study were to examine the associations between positive maternal mental health and children's internalizing and externalizing symptoms, and to ascertain whether positive maternal mental health moderated the associations between prenatal stress and children's internalizing and externalizing symptoms. This study is based on the Norwegian Mother, Father, and Child Cohort Study (MoBa), and comprised 36,584 mother-child dyads. Prenatal stress was assessed using 41 self-reported items measured during pregnancy. Positive maternal mental health (self-efficacy, self-esteem, and enjoyment) was assessed by maternal report during pregnancy and postpartum. Child internalizing and externalizing symptoms were assessed by maternal report at age 5. Structural equation modeling was used for analysis. Maternal self-efficacy, self-esteem, and enjoyment were negatively associated with internalizing and externalizing symptoms in males and females. The association between prenatal stress and internalizing symptoms in males was stronger at low than at high levels of maternal self-esteem and enjoyment, whereas for females, the association was stronger at low than at high levels of maternal self-esteem and self-efficacy. This study provides evidence of associations between positive maternal mental health and children's mental health, and suggests that higher positive maternal mental health may buffer against the impacts of prenatal stress. Positive maternal mental health may represent an important intervention target to improve maternal-child well-being and foster intergenerational resilience.

BACKGROUND: Very little research has described risk of suicidal ideation and suicide attempt among transgender youth using high-quality, nationally representative data. We aimed to assess risk of suicidality among transgender and sexual minority adolescents in Canada. METHODS: We analyzed a subsample of adolescents aged 15-17 years from the 2019 Canadian Health Survey on Children and Youth, a nationally representative, cross-sectional survey. We defined participants' transgender identity (self-reported gender different from sex assigned at birth) and sexual minority status (self-reported attraction to people of the same gender) as exposures, and their self-reported previous-year suicidal ideation and lifetime suicide attempt as outcomes. RESULTS: We included 6800 adolescents aged 15-17 years, including 1130 (16.5%) who indicated some degree of same-gender attraction, 265 (4.3%) who were unsure of their attraction and 50 (0.6%) who reported a transgender identity. Compared with cisgender, heterosexual adolescents, transgender adolescents showed 5 times the risk of suicidal ideation (95% confidence interval [CI] 3.63 to 6.75; 58% v. 10%) and 7.6 times the risk of suicide attempt (95% CI 4.76 to 12.10; 40% v. 5%). Among cisgender adolescents, girls attracted to girls had 3.6 times the risk of previous-year suicidal ideation (95% CI 2.59 to 5.08) and 3.3 times the risk of having ever attempted suicide (95% CI 1.81 to 6.06), compared with their heterosexual peers. Adolescents attracted to multiple genders had 2.5 times the risk of suicidal ideation (95% CI 2.12 to 2.98) and 2.8 times the risk of suicide attempt (95% CI 2.18 to 3.68). Youth questioning their sexual orientation had twice the risk of having attempted suicide in their lifetime (95% CI 1.23 to 3.36). INTERPRETATION: We observed that transgender and sexual minority adolescents were at increased risk of suicidal ideation and attempt compared with their cisgender and heterosexual peers. These findings highlight the need for inclusive prevention approaches to address suicidality among Canada's diverse youth population.

BACKGROUND: Adverse childhood experiences (ACEs) are cross-sectionally associated with headache, including migraine, in pediatric populations. OBJECTIVE: The objective of this study was to determine whether ACEs are prospectively associated with incident health-professional diagnosed migraine and prevalence of non-migraine frequent headache in adolescence, either directly or indirectly through symptoms of depression and anxiety. METHODS: We used data from the National Longitudinal Survey of Children and Youth, a Canadian cohort study that followed children aged 0/1 at baseline, and the person most knowledgeable about them (PMK) until the child reached adolescence. The PMK reported on 14 ACEs (e.g., parental death) when the child was 4/5 and 6/7 years, and symptoms of depression and anxiety in late childhood (age 8/9 years), using a validated tool. Migraine (primary outcome) was ascertained via PMK report of a health-professional diagnosis, and non-migraine frequent headache (>1 time per week) was adolescent self-report, both measured at age 14/15. We estimated direct and indirect effects (IEs) on the log-odds scale through symptoms of depression and anxiety (mediator). We adjusted for sex, parental migraine, and economic deprivation. The analytic sample sizes were: n = 2058 (migraine) and n = 1730 (frequent headache). RESULTS: There were nunweighted = 71 respondents with migraine (3.4%, 71/2058) and nunweighted = 204 with non-migraine frequent headache (11.8%, 204/1730). Most respondents experienced no ACEs (weighted percentage = 55.7), followed by 1 ACE (weighted percentage = 34.7) and greater than or equal to two ACEs (weighted percentage = 9.6), respectively. There were direct associations between experiencing one (odds ratio [OR] = 1.71, 95% confidence interval [CI]: 1.01-2.87) and equal to or greater than two (OR = 2.33, 95% CI: 1.13-4.80) ACEs and migraine, but not for non-migraine frequent headache. There were no indirect relationships through symptoms of depression and anxiety for migraine (1 ACE: OR = 1.06, 95% CI: 0.99-1.13 and ≥2 ACEs: OR = 1.11, 95% CI: 0.98-1.28) or non-migraine frequent headache (1 ACE: OR = 0.99, 95% CI: 0.95-1.03 and ≥2 ACEs: OR = 0.98, 95% CI: 0.90-1.07). CONCLUSIONS: ACEs may confer an increased risk of migraine onset in adolescence. The association was not explained by symptoms of depression and anxiety in late childhood.

BACKGROUND: Suicide is a leading cause of death, particularly for young adults. Suicidal behaviours are influenced by a wide-range of personal, social, and cultural factors. Emerging evidence suggests that daily changes in meteorological conditions, including temperature, increases the risk of suicide. METHODS: We conducted a systematic review and meta-analysis of studies that examined associations between either daily, or weekly, variations for eight meteorological variables and suicide outcomes (attempts, or deaths). Meta-analytic methods were applied to derive summary measures of association using random effect models. We assessed the heterogeneity in these associations by region and biological sex. RESULTS: We identified 29 studies of suicide. Of these, 26 reported associations between temperature, while fewer studies reported on rain (n = 4), solar radiation (n = 4), humidity (n = 3), sunshine (n = 3), atmospheric pressure (n = 2), wind (n = 2) and cloud cover (n = 2). The overall relative risk for suicide deaths/attempts per 1 °C increase in ambient temperature was 1.016 (95% CI: 1.013-1.019). Subgroup analysis of temperature found stronger associations with suicide when using the maximum rather than the mean daily temperature, among men, and for completed suicides relative to attempts. Regionally, the strongest associations were found in the East Asia and Pacific region. While associations were found for solar radiation and cloud coverage and suicide, we did not undertake a meta-analysis for these exposures as it was not possible to standardize measures of association across studies. Statistically significant associations were not observed for other identified meteorological variables. CONCLUSIONS: Our findings suggest that daily increases in temperature increase the risk of suicide, particularly, among men and in the East Asia and Pacific region.

PURPOSE: To estimate associations between multiple forms of substance use with self-harming thoughts and behaviours, and to test whether gender is an effect modifier of these associations, both independently and along with perceived risk of cannabis use. METHODS: Data were drawn from the 2018 Norwegian Students' Health and Wellbeing Study (SHoT 2018). A national sample of n = 50,054 full-time Norwegian students (18-35 years) pursuing higher education completed a cross-sectional student health survey, including questions on past-year self-harm: non-suicidal thoughts of self-harm, non-suicidal self-harm, suicidal thoughts, and suicide attempt. Students reported their frequency of past-year alcohol use (range: never to ≥ 4 times/ week), illicit substance consumption, and perceived risk of cannabis use. The AUDIT and CAST screening tools measured problematic alcohol and cannabis consumption, respectively. We used logistic regression modelling adjusted for age, symptoms of depression and anxiety, and financial hardship (analytic sample range: n = 48,263 to n = 48,866). RESULTS: The most frequent alcohol consumption category (≥ 4 times/ week) was nearly always associated with more than a two-fold increased likelihood of self-harm. Less frequent alcohol consumption was associated with reduced odds of suicidal thoughts [monthly or less: OR = 0.87 (95% CI: 0.75-1.00), 2-4 times/month: OR = 0.79 (95% CI: 0.69-0.91), and 2-3 times/ week: OR = 0.83 (95% CI: 0.71-0.98)]. Problematic alcohol consumption was associated with most outcomes: odds ranging from 1.09 (95% CI: 1.01-1.18) for suicidal thoughts to 1.33 (95% CI: 1.00-1.77) for suicide attempt. There was evidence of multiple illicit substance by gender interactions: consumption of all but one illicit substance category (other drug use) was associated with all four forms of self-harm for women, but findings among men were less clear. Among men, only one illicit substance category (stimulant) was associated with most forms of self-harm. Women, but not men, who perceived cannabis use as a health risk were more likely to experience non-suicidal thoughts as cannabis consumption increased, and with harmful consumption patterns. CONCLUSION: Frequent alcohol consumption is associated with increased risk of self-harm and suicidality for young women and men. Associations between illicit substance use and self-harm and suicidality appear stronger in women compared to men.

BACKGROUND: Spinal pain and major depression are prevalent conditions in adult populations and are particularly impactful in the military. However, the temporal relationship between these two conditions remains poorly understood. METHODS: Using data extracted from electronic medical records, we assessed the association between incident diagnoses of spinal pain and major depression in a cohort of 48,007 Canadian Armed Forces personnel followed from January 2017 to August 2018. We used multivariate Poisson regression to measure the association between the period prevalence of these two conditions. We used probabilistic bias modelling to correct our estimates for misclassification of spinal pain and major depression. RESULTS: After correcting for misclassification with probabilistic bias modelling, subjects newly diagnosed with spinal pain during the study period were 1.41 times (95% interval 1.25, 1.59) more likely also to be diagnosed with incident major depression, and personnel newly diagnosed with major depression were 1.28 times (95% interval 1.17, 1.39) more likely also to be diagnosed with spinal pain, compared to undiagnosed counterparts of the same age and sex. Without bias corrections, we would have overestimated the magnitude of the association between major depression and spinal pain by a factor of approximately 2.0. CONCLUSION: Our results highlight a moderate and bi-directional association between two of the most prevalent disorders in military populations. Our results also highlight the importance of correcting for misclassification in electronic medical record data research.

Driving under the influence of cannabis is a growing public health concern among young people. This study assessed the prevalence of cannabis-impaired driving and its related sociodemographic, psychological, and knowledge-based correlates among Canadian adolescents. The sample for this study were drawn from the 2017 Ontario Student Health and Drug Use Survey (OSDUHS), consisting of high school students with valid driver's licenses (mean age = 16.8, SD = 0.71) who were asked about their driving behaviors, drug use, and attitudes regarding cannabis use (N = 1161). A multivariable logistic regression model was performed to determine the strongest correlates of driving after cannabis use. The prevalence of past-year driving within an hour of cannabis use was 10.3% (95% CI: 7.8,13.5). In the final multivariable model, probable cannabis dependence (OR = 12.7, 95%CI: 3.4,47.7), low perceived risk of cannabis use (OR = 5.3, 95%CI: 2.5,11.1), pro-legalization attitudes, (OR = 4.3, 95%CI: 2.0,9.1) and male gender (OR = 2.6, 95%CI: 1.5,4.5) were significantly associated with driving under the influence of cannabis. Other correlates of driving after cannabis user were risky driving behaviors, including past-year texting and driving and driving after alcohol use. There are various correlates of driving under the influence of cannabis, including attitudes related to cannabis which may be amenable to intervention. Future efforts should continue to monitor the prevalence of cannabis-impaired driving in this population and determine whether changes in students' attitudes surrounding cannabis are linked to behavioural changes.

BACKGROUND: Recruitment and engagement of clusters in a cluster randomized controlled trial can sometimes prove challenging. Identification of successful or unsuccessful strategies may be beneficial in guiding future researchers in conducting their cluster randomized controlled trial. This study aimed to identify strategies that could be used to facilitate the delivery of cluster randomized controlled trials in hospitals. METHODS: The study employed the Consolidated Framework for Implementation Research-Expert Recommendations for Implementing Change matching tool. The barriers and enablers to cluster randomized controlled trial conduct identified in our previously conducted studies served as a means of determinant identification for the conduct of cluster randomized controlled trials. These determinants were mapped to Consolidated Framework for Implementation Research constructs and then matched to Expert Recommendations for Implementing Change compilation strategies using the Consolidated Framework for Implementation Research-Expert Recommendations for Implementing Change matching tool. RESULTS: The Expert Recommendations for Implementing Change strategies matched to at least one determinant Consolidated Framework for Implementation Research construct were as follows: (1) 'Identify and prepare champions', (2) 'Conduct local needs assessment', (3) 'Conduct educational meetings', (4) 'Inform local opinion leaders', (5) 'Build a coalition', (6) 'Promote adaptability', (7) 'Develop a formal implementation blueprint', (8) 'Involve patients/consumers and family members', (9) 'Obtain and use patients/consumers and family feedback', (10) 'Develop educational materials', (11) 'Promote network weaving', (12) 'Distribute educational materials', (13) 'Access new funding' and (14) 'Develop academic partnerships'. CONCLUSION: This study was intended as a step in the research agenda aimed at facilitating cluster randomized controlled trial delivery in hospitals and can act as a resource for future researchers when planning their cluster randomized controlled trial, with the expectation that the strategies identified here will be tailored to each context.

OBJECTIVE: The Canadian 24-Hour Movement Guidelines for Children and Youth recommend at least 60 minutes of physical activity per day, 2 hours or less of recreational screen time per day, and 9 to 11 hours of sleep per night for 5 to 13 years old and 8 to 10 hours per night for 14 to 17 years old. This study examined the association between meeting these guidelines and psychological distress among adolescents. METHODS: The present cross-sectional sample included 6,364 students aged 11 to 20 years from the 2017 Ontario Student Drug Use and Health Survey. This provincially representative school-based survey is based on a 2-stage cluster design. A confirmatory factor analysis (CFA) was first conducted to confirm the factor structure of the K6, and structural equation modeling adjusted for age, sex, ethnoracial background, subjective socioeconomic status, and body mass index z-score was used to investigate the association between meeting the 24-Hour Movement Guidelines and K6 factors among adolescents. RESULTS: The CFA demonstrated that a 2-factor model (representing anxiety and depressive symptoms) of the K6 fit the data well. The anxiety and depression items demonstrated a composite reliability (Cronbach's α) of 0.86 and 0.83, respectively, indicating a high level of internal consistency. Compared to meeting none of the recommendations, meeting all 3 movement behavior recommendations was associated with lower anxiety (ß = -0.076; P = 0.028) and depressive symptoms (ß = -0.067; P = 0.028). Meeting the screen time + sleep duration recommendations had the strongest association with anxiety (ß = -0.157; P < 0.001) and depressive symptoms (ß = -0.139; P < 0.001), followed by meeting the sleep duration recommendation only for both anxiety (ß = -0.135; P < 0.001) and depressive symptoms (ß = -0.106; P < 0.001). CONCLUSIONS: Meeting the 24-Hour Movement Guidelines was associated with lower anxiety and depressive symptoms among adolescents, and these associations appear mainly driven by meeting the sleep duration recommendation.

PURPOSE: Parenting practices represent important and modifiable factors for health and wellbeing in children and adolescents; however, strength and quality of studies examining relationships between parenting practices in childhood and risk of depression and anxiety in adolescence are unclear. The objective of this systematic review was to synthesize the longitudinal literature that describes these associations. METHODS: Six electronic databases were searched for articles published through March 2018. Eligible articles were published in the English language, peer-reviewed, and had prospective cohort study designs. Articles eligible for inclusion examined positive and negative parenting practices of parents and/or guardians when study subjects were between 0 and 9 years of age, and symptoms of depression, anxiety, and internalizing symptoms when subjects were between 10 and 19 years of age. Heterogeneity of included articles precluded meta-analysis: findings were reported narratively. RESULTS: 4558 references were screened for inclusion, and 19 articles met eligibility criteria and were included for review. Ten articles examined positive parenting practices, and four demonstrated statistically significant associations between positive parenting practices and lower risk of adolescent depression, anxiety, and/or internalizing symptoms. Fifteen articles examined negative parenting practices, and five demonstrated significant associations between negative parenting practices and higher risk of adolescent depression, anxiety, and/or internalizing symptoms. CONCLUSION: This review demonstrates that the evidence base supporting longitudinal associations between parenting practices in childhood and adolescent symptoms of depression, anxiety, and internalizing problems is inconsistent. Findings from this review highlight limitations of the existing literature and identify understudied parenting dimensions that require further investigation.

PURPOSE: The present study examined associations between nonmedical use of prescription opioids and serious psychological distress, suicidal ideation, and suicide attempts, and tested whether age and sex moderate these relationships. METHODS: Data on 5582 adolescents were obtained from a representative province-wide survey of students in grades 7 through 12 (mean age: 15.3 years) across Ontario, Canada. Nonmedical use of prescribed opioids in the last 12 months was categorized in "no use", "infrequent use (1-2 times)", and "regular use (3 times or more)". Logistic regression analysis was adjusted for age, sex, ethnicity, subjective socioeconomic status, and other substance use (i.e., tobacco cigarette, alcohol, cannabis). RESULTS: Overall, regular nonmedical use of prescription opioids was strongly associated with greater odds of serious psychological distress (OR: 3.47; 95% CI 1.42-8.45), suicidal ideation (OR: 2.73; 95% CI 1.84-4.05), and suicide attempts (OR: 3.21; 95% CI 1.40-7.37). However, infrequent nonmedical use of prescription opioids was associated with greater odds of serious psychological distress (OR: 1.79; 95% CI 1.08-2.98) and suicidal ideation (OR: 1.63; 95% CI 1.20-2.21), but not suicide attempts (OR: 1.84; 95% CI 0.76-4.45). Age-stratified analyses showed that both infrequent (OR: 1.61; 95% CI 1.01-2.58) and regular (OR: 3.40; 95% CI 2.11-5.46) nonmedical use of prescription opioids was strongly associated with greater odds of suicidal ideation among 15- to 20-year-olds, but not 11- to 14-year-olds. CONCLUSION: These findings suggest that nonmedical use of prescription opioids is strongly associated with mental health problems among adolescents. Future research using a longitudinal design is needed to confirm age differences and temporality.

BACKGROUND: Adolescence is a high-risk period for the onset of suicidal thoughts and behaviors. Identification of preceding patterns of internalizing and externalizing symptoms that are associated with subsequent suicidal thoughts may offer a better understanding of how to prevent adolescent suicide. METHODS: Data from the National Longitudinal Survey of Children and Youth, a prospective population-based Canadian cohort, contained Child Behavior Checklist items which were used to examine profiles and transitions of internalizing and externalizing symptoms in children, aged 6-11 years (n = 8266). The association between these profiles/transitions and suicidal thoughts in adolescents was examined using multivariate logistic regression modeling. RESULTS: Latent profile analyses identified four measurement invariant profiles of internalizing and externalizing symptoms at ages 6/7 and 10/11: (1) low on all symptoms, (2) moderate on all symptoms, (3) high on all symptoms, and (4) high on hyperactivity/inattention and internalizing. Recurrent (homotypic or heterotypic) and increasing symptoms from 6/7 to 10/11 were associated with suicidal thoughts in adolescence, compared to those with stable low symptoms. Those with decreasing symptoms from 6/7 to 10/11 were not at increased risk of suicidal thought in adolescence. CONCLUSIONS: While patterns of recurrent symptoms were associated with suicidal thoughts, a similar association was observed between profiles at age 10/11 years and suicidal thoughts. This suggests that the recent assessments of mental health symptoms in children may be as sufficient a predictor of adolescent suicidal thought as transition profiles.

BACKGROUND: Exposure to stressful life events is an established risk factor for the development of adolescent mental disorder. Growing evidence also suggests that neighbourhood social environments, including strong social cohesion, could have a protective effect on mental health. However, little is known about how neighbourhood social cohesion may buffer against the effects of stressful life events on adolescent mental health. Our aim was to assess whether neighbourhood social cohesion modifies the association between stressful life events and adolescent mental health outcomes. METHODS: Data were drawn from a nationally-representative prospective sample of Canadian adolescents, including 5183 adolescents aged 12/13 years at T1 and 14/15 years at T2. Caregivers reported neighbourhood social cohesion at T1, and exposure to stressful life events between T1 and T2. Symptoms of mental health and behaviour problems were self-reported by adolescents at T1 and T2. Multivariable logistic regression was used to determine whether the relationship between stressful life events and outcomes was modified by neighbourhood social cohesion. RESULTS: Associations between stressful life events and adolescent outcomes were statistically significantly lower in neighbourhoods with greater social cohesion for: depression/anxiety (high cohesion OR = 0.98 v. low cohesion OR = 3.11), suicidal ideation (ORhigh = 1.30 v. ORlow = 5.25), aggression/conduct disorder (ORhigh = 1.09 v. ORlow = 4.27), and property offence (ORhigh = 1.21 v. ORlow = 4.21). CONCLUSIONS: Greater neighbourhood social cohesion appeared to buffer the effects of stressful life events on several domains of adolescent mental health. This potentially presents a target for public health intervention to improve adolescent mental health and behavioural outcomes.
