Derivation of some contemporary scales to measure adolescent risk-taking in Canada

Young mother risk-taking moderates doula home visiting impacts on parenting and toddler social-emotional development

This longitudinal randomized controlled trial examined the impact of a doula home visiting intervention for young, low-income mothers on parenting and toddler social-emotional development and tested whether intervention effects were moderated by maternal emotional and behavioral health characteristics. 156 mothers were offered home visits from a home visitor starting in mid-pregnancy through several years postpartum, with a community doula also working with the mother during pregnancy and after the birth. 156 received case management. Interviews, video recordings of mother-child interactions, and toddler assessments were conducted at 3 weeks, 3 months, 13 months, and 30 months of age. Intent-to-treat analyses conducted with the full sample showed some intervention effects. Moderation analyses, however, showed that most effects were concentrated among mothers engaged in high levels of risk-taking (delinquent behaviors, school suspensions, smoking, alcohol use, sexual risk-taking). Among higher risk-taking mothers, the intervention was related to less intrusiveness during early infancy, less psychological and physical aggression during toddlerhood, more sensitive parenting attitudes, and greater toddler social relatedness. Maternal depressive symptoms were only a moderator for toddler behavior problems. These findings suggest that doula home visiting may be a particularly effective model for enhancing sensitive, non-aggressive parenting among young mothers with a history of risk-taking behavior.

Correlations between weight perception and overt risk-taking among Canadian adolescents

OBJECTIVE

Perceptions of body weight represent an important health issue for Canadian adolescents. While associations between weight perception and mental health concerns like eating disorder symptomatology are well established, there is need for more Canadian evidence about how weight perception is associated with overt risk-taking among adolescents, and further how such associations differ by biological sex.

METHODS

We conducted a national analysis of grade 9-10 students participating in the 2017-2018 cycle of the Health Behaviour in School-aged Children (HBSC) study in Canada. This analysis described contemporary patterns of alternate weight perception and then examined the strength and statistical significance of such associations by biological sex, with tobacco, alcohol, and cannabis use, binge drinking, fighting, and illicit drug use as outcomes. Behaviours were considered both individually and in combination. Analyses were descriptive and analytical, with regression models accounting for the nested and clustered nature of the sampling approach.

RESULTS

Responses from 2135 males and 2519 females were available for a complete case series analysis. A total of 26% and 35% of males and females, respectively, perceived themselves as "too fat" while 20% and 9% identified as "too thin". Females perceiving themselves as "too fat" reported higher likelihoods of engaging in individual and scaled indicators of overt risk-taking. Conversely, among males, alternate weight perception was associated with lower levels of such behaviours.

CONCLUSION

As males and females perceive and react to weight perception differently, clinical and health promotion strategies should be developed and uniquely targeted to groups of adolescents in regards to weight perception and risk-taking.

Compositional associations of time spent in sleep, screen time, and physical activity with polysubstance use in adolescents

This study of grade 6-10 students used compositional analysis to examine the relationship between the movement behavior composition (time in sleep, screen time, and physical activity) and polysubstance use (frequency of using cigarettes, alternative tobacco products, alcohol, cannabis, and illicit drugs). In grades 6-8 students and grades 9-10 girls: 1) sleep was negatively associated with polysubstance use, 2) screen time was positively associated with polysubstance use, and 3) reallocating physical activity or screen time into sleep was associated with lower polysubstance use. In grades 9-10 boys, reallocating 60 min/day from physical activity into screen time or sleep was associated with greater polysubstance use.

Mechanisms accounting for gendered differences in mental health status among young Canadians: A novel quantitative analysis

Adolescent girls consistently report worse mental health than boys. This study used reports from a 2018 national health promotion survey (n = 11,373) to quantitatively explore why such gender-based differences exist among young Canadians. Using mediation analyses and contemporary social theory, we explored mechanisms that may explain differences in mental health between adolescents who identify as boys versus girls. The potential mediators tested were social supports within family and friends, engagement in addictive social media use, and overt risk-taking. Analyses were performed with the full sample and in specific high-risk groups, such as adolescents who report lower family affluence. Higher levels of addictive social media use and lower perceived levels of family support among girls mediated a significant proportion of the difference between boys and girls for each of the three mental health outcomes (depressive symptoms, frequent health complaints, and diagnosis of mental illness). Observed mediation effects were similar in high-risk subgroups; however, among those with low affluence, effects of family support were somewhat more pronounced. Study findings point to deeper, root causes of gender-based mental health inequalities that emerge during childhood. Interventions designed to reduce girls' addictive social media use or increase their perceived family support, to be more in line with their male peers, could help to reduce differences in mental health between boys and girls. Contemporary focus on social media use and social supports among girls, especially those with low affluence, warrant study as the basis for public health and clinical interventions.

The actuality and influences of undergraduates' participation in high impact educational practices in Chinese universities

High Impact Educational Practices (HIPs) are effectively educational practices that have an important impact on student learning and development. The purpose of this study is to investigate the impact of different types of high-impact educational activities on students' learning outcomes. The data comes from the 2019 "tracking research survey on learning and development of Chinese college students," in which undergraduates from 39 Chinese colleges and universities participated. This study first clarified the concept and classification of high-impact educational activities, and then used multiple linear regression analysis to analyze the impact of three types of high-impact educational activities, including extended learning activities, research-related activities, and social practice activities, on students' learning gains. It's found that most Chinese college students do not perform well on HIPs, while the "Double First-Class" university students engage more than other colleges. Participating in HIPs has a significant impact on students' knowledge, ability and values, especially on the latter two. This study provides valuable enlightenment for universities on how to promote students' participation in high impact educational activities and improve the quality of higher education.

Development of a novel continuous measure of adolescent mental health inspired by the dual-factor model

Background

According to the Dual-factor Model, mental health is comprised of two related constructs: subjective well-being and psychopathology. Combining these constructs can provide a more accurate and comprehensive assessment of adolescent mental health than considering either on its own. The model suggests the need to group mental health into four distinct categories, which does not recognize its potential continuum and adds statistical complexity. In this study, we developed a continuous measure inspired by, and as a complement to, the Dual-factor Model. Our goal was to demonstrate a novel approach to developing a valid measure for use in public health research that captures varying mental health states more accurately than traditional approaches and has advantages over the categorical version.

Methods

Self-report data are from the 2014 Canadian Health Behavior in School-aged Children study (n = 21,993). Subjective well-being was measured by combining indicators of life satisfaction, positive affect, and negative affect. Internalized and externalized symptoms scales were combined to measure psychopathology. The continuous dual-factor measure was created by subtracting standardized psychopathology scores from standardized subjective well-being scores. Construct validity was assessed using multivariable linear regression by examining associations between factors known to be associated with adolescent mental health status (demographic characteristics, social and academic functioning, and specific indicators of mental health) and average mental health scores.

Results

The average age was 14.0 (SD = 1.41) years. The continuous mental health score ranged from 5 to 67 [Mean (SD): 50.1 (9.8)], with higher scores indicating better overall mental health. The nature and direction of the associations examined supported construct validity. Being from a more affluent family, and having more supportive relationships with family, peers, teachers, and classmates was associated with greater mental health (Cohen’s d: 0.65 to 1.63). Higher average marks were also associated with better mental health. Average mental health scores were much lower if students reported feeling hopeless or rated their health as fair or poor.

Conclusion

A continuous measure of mental health based on the Dual-factor Model appears to be a comprehensive and valid measure with applications for research aimed at increasing our understanding of adolescent mental health.

A Systematic Review on Economic Evaluation Studies of Diagnostic and Therapeutic Interventions in the Middle East and North Africa

INTRODUCTION

Due to the increase in healthcare budget constraint, economic evaluation (EE) evidence is increasingly required to inform resource allocation decisions. This study aimed to systematically review quantity, characteristics, and quality of full EE studies on diagnostic and therapeutic interventions conducted in 26 Middle East and North Africa (MENA) countries.

METHODS

PubMed and Scopus databases were comprehensively searched to identify the published EE studies in the MENA region. The quality of reviewed studies was evaluated using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist.

RESULTS

The search identified 69 studies. The cost-utility approach was adopted in 49 studies (71 %). More than half (38 studies; 55 %) were conducted in Iran and Turkey. Sixteen countries (62 %) did not have any EE studies. The most frequently analyzed therapeutic areas were infectious diseases (19 studies; 28 %), cardiovascular diseases (11 studies; 16 %), and malignancies (10 studies; 14 %). Ten studies (14 %), 46 (67 %), 12 (17 %), and 1 study (1 %) were classified as excellent, high, moderate, and poor quality, respectively. The mean of items reported was 85.10 % (standard deviation 13.32 %). Characterizing heterogeneity, measurement of effectiveness, time horizon, and discount rate were missed in 21 (60 %), 22 (32 %), 20 (29 %) and 15 (25 %) studies, respectively. Data on effectiveness and utility relied primarily on studies conducted outside the region.

CONCLUSIONS

The quantity of EE studies in the MENA region remains low; however, overall quality is high to excellent. The availability of local data, capacity building, and national guidelines are vital to improve both the quantity and quality of EE studies in the region.

Development of a dual-factor measure of adolescent mental health: an analysis of cross-sectional data from the 2014 Canadian Health Behaviour in School-aged Children (HBSC) study

INTRODUCTION

Studies of adolescent mental health require valid measures that are supported by evidence-based theories. An established theory is the dual-factor model, which argues that mental health status is only fully understood by incorporating information on both subjective well-being and psychopathology.

OBJECTIVES

To develop a novel measure of adolescent mental health based on the dual-factor model and test its construct validity.

DESIGN

Cross-sectional analysis of national health survey data.

SETTING AND PARTICIPANTS

Nationally weighted sample of 21 993 grade 6-10 students; average age: 14.0 (SD 1.4) years from the 2014 Canadian Health Behaviour in School-aged Children study.

MEASURES

Self-report indicators of subjective well-being (life satisfaction, positive and negative affect), and psychopathology (psychological symptoms and overt risk-taking behaviour) were incorporated into the dual-factor measure. Characteristics of adolescents families, specific mental health indicators and measures of academic and social functioning were used in the assessment of construct validity.

RESULTS

Proportions of students categorised to the four mental health groups indicated by the dual-factor measure were 67.6% 'mentally healthy', 17.5% 'symptomatic yet content', 5.5% 'asymptomatic yet discontent' and 9.4% 'mentally unhealthy'. Being mentally healthy was associated with the highest functioning (greater social support and academic functioning) and being mentally unhealthy was associated with the worst. A one-unit increase (ranges=0-10) in peer support (OR 1.19; 95% CI 1.15 to 1.22), family support (OR 1.32; 95% CI 1.28 to 1.36), student support (OR 1.20; 95% CI 1.17 to 1.24) and average school marks (OR 1.18; 95% CI 1.10 to 1.27) increased the odds of being symptomatic yet content versus mentally unhealthy. Mentally healthy youth were the most likely to live with both parents (77% vs ≤65%) and report their family as well-off (62% vs ≤53%).

CONCLUSIONS

We developed a novel, construct valid dual-factor measure of adolescent mental health. This potentially provides a nuanced and comprehensive approach to the assessment of adolescent mental health that is direly needed.

The cascade of care in managing hypertension in the Arab world: a systematic assessment of the evidence on awareness, treatment and control

BACKGROUND

Hypertension is a leading risk factor for mortality and morbidity globally and in the Arab world. We summarize the evidence on awareness, treatment, and control of hypertension, to assess the extent of gaps in the hypertension continuum of care. We also assess the influence of gender and other social determinants at each level of the cascade of care.

METHODS

We searched MEDLINE and SSCI databases for studies published between 2000 and 2017, reporting the rates of awareness, treatment or control of hypertension and/or their determinants in the Arab region. We included sources on both general populations and on clinical populations. The review process was based on the PRISMA guidelines. We present rates on the three stages of the care cascade corresponding to (1) awareness (2) treatment and (3) control of blood pressure, and estimated the losses that occur when moving from one stage to another. We also take stock of the evidence on social determinants and assess the statistical significance of gender differences in awareness, treatment and control.

RESULTS

Data from 73 articles were included. Substantial proportions of hypertensives were lost at each step of the hypertension care continuum, with more missed opportunities for care resulting from lack of awareness of hypertension and from uncontrolled blood pressure. More than 40% and 19% of all hypertensive individuals were found to be unaware and to have uncontrolled blood pressure, respectively, but among individuals diagnosed with hypertension, less than 21% were untreated. Awareness rates were higher among women than men but this advantage was not consistently translated into better blood pressure control rates among women.

CONCLUSIONS

This analysis of the cascade of care indicates that barriers to proper diagnosis and adequate control are greater than barriers to delivery of treatment, and discusses potential factors that may contribute to the gaps in delivery.

Clusters of Contemporary Risk and Their Relationship to Mental Well-Being Among 15-Year-Old Adolescents Across 37 Countries

PURPOSE

Adolescents' mental well-being has become a growing public health concern. Adolescents' daily lives and their engagement in risks have changed dramatically in the course of the 21st century, leading to a need to update traditional models of risk to include new exposures and behaviors. To date, studies have examined the relationship between (mainly traditional) risk behaviors and adolescent mental well-being or looked at risk factors that jeopardize mental well-being such as lack of social support but have not combined them together to highlight the most significant risks for adolescent mental well-being today. The present study included new and traditional risk behaviors and risk factors, robustly derived an empirically based model of clusters of risk, and examined the relative association of these clusters to adolescent mental well-being.

METHODS

Data from the 2017-2018 Health Behaviours in School-aged Children study were used. The sample included 32,884 adolescents (51.7% girls) aged 15 years from 37 countries and regions. The principal component analysis was used to determine the existence of clusters of risk, using 21 items related to adolescent mental well-being that included both risk behaviors (e.g., substance use) and risk factors (e.g., peer support). Analysis was conducted in both a randomly split training and test set and in gender separate models. Mixed-effects logistic regressions examined the association between clusters of risk and mental well-being indices (low life satisfaction and psychosomatic complaints).

RESULTS

Seven clusters of risk were identified: substance use and early sex, low social support, insufficient nutrition, bullying, sugary foods and drinks, physical health risk, and problematic social media use (SMU). Low social support and SMU were the strongest predictors of low life satisfaction (odds ratios = 2.167 and 1.330, respectively) and psychosomatic complaints (odds ratio = 1.687 and 1.386, respectively). Few gender differences in predictors were found. Exposure to bullying was somewhat more associated with psychosomatic complaints for girls, whereas physical health risk was associated with reduced relative odds of low life satisfaction among boys. Split-sample validation and out-of-sample prediction confirmed the robustness of the results.

CONCLUSIONS

The results highlight the importance of contemporary clusters of risk, such as low social support and SMU in the mental well-being of young people and the need to focus on these as targets for prevention. We propose that future studies should use composite risk measures that take into account both risk behaviors and risk factors to explain adolescents' mental well-being.

Adolescents' engagement in multiple risk behaviours is associated with concussion

Background

The objective of this study was to investigate the relationship between engagement in multiple risk behaviours (MRB) and concussion amongst youth.

Methods

This was a cross-sectional study that used survey data collected from 3059 students in grades 6–10 (approximate ages 11–15 years) from Ontario, Canada. Students reported whether or not they had a medically diagnosed concussion within the previous 12 months and the frequency that they participated in several risky behaviours including fighting, bullying, smoking, drinking alcohol, using illicit drugs, drinking caffeinated beverages, not using protective equipment, and having unsafe sex. Responses to the risky behavior items were used to create a MRB score. The association between MRB and concussion was explored using logistic regression that controlled for several confounding variables.

Results

Approximately 10.7% of students reported that they had a medically diagnosed concussion within the past year. A dose-response relationship was found between MRB and concussion among students in grades 9–10, while in grades 6–8 students only those in the highest MRB quartile had an increased likelihood of concussion. The relative odds for concussion in the highest versus the lowest MRB quartile were 4.67 (95% confidence interval: 2.33, 9.35) in grades 9–10 students and 2.94 (95% confidence interval, 1.90, 4.56) in grades 6–8 students.

Conclusions

Engagement in MRB may be an important etiologic component of adolescent concussion. Future studies should address whether behavioural interventions designed to decrease engagement in MRB reduce the risk of concussion and other injuries.

A Contemporary Profile of the Mental Health of Girls from Farm and Non-Farm Environments

Background: The mental health of young people has become a public health priority in recent years. Many early symptoms of mental health disorders first appear during adolescence. The aim of this study was to develop a contemporary profile of the mental health of Canadian adolescent girls from farms and determine whether they differed from girls with non-farm backgrounds.Methods: Cross-sectional analyses of an established, school-based survey, the Health Behaviour in School-Aged Children (2014) were conducted. Study subjects were adolescent girls who reported living or working (n = 1,346) and not living or working (n = 13,158) on a farm and attending schools in rural, small, medium and large/metropolitan centers. Scales examining positive (prosocial behaviour, life satisfaction) and negative (psychological problems, overt risk-taking) mental health indicators were compared between the two groups of girls by grade and community size.Results: Both farm and non-farm girls in upper grades reported lower life satisfaction scores and higher scores for psychological problems and overt risking-taking compared to girls in lower grades. By community size, girls from farms in the most rural schools reported more positive mental health than non-farm girls, with the exception of overt risk-taking, where girls in grades 9-10 from the most rural backgrounds reported markedly higher levels of risk-taking, particularly girls from farms.Conclusions: This study identified differences in mental health of girls from farms as community size increases, with more positive indicators among girls in the most rural communities. However, across all community sizes, overt risk-taking was higher in girls from farms. Thus, it appears that agrarian culture and norms have both protective and negative effects on the mental health of girls from farms.

Premature Myocardial Infarction in the Middle East and North Africa: Rationale for the Gulf PREVENT Study

The Middle East and North Africa (MENA) region has a high burden of morbidity and mortality due to premature (≤55 years in men; ≤65 years in women) myocardial infarction (MI) and acute coronary syndrome (ACS). Despite this, the prevalence of risk factors in patients presenting with premature MI or ACS is incompletely described. We compared lifestyle, clinical risk factors, and biomarkers associated with premature MI/ACS in the MENA region with selected non-MENA high-income countries. We identified English-language, peer-reviewed publications through PubMed (up to March 2018). We used the World Bank classification system to categorize countries. Patients with premature MI/ACS in the MENA region had a higher prevalence of smoking than older patients with MI/ACS but a lower prevalence of diabetes, hypertension, and dyslipidemia. Men with premature MI/ACS had a higher prevalence of smoking than women but a lower prevalence of diabetes and hypertension. The MENA region had sparse data on lifestyle, diet, psychological stress, and physical activity. To address these knowledge gaps, we initiated the ongoing Gulf Population Risks and Epidemiology of Vascular Events and Treatment (Gulf PREVENT) case-control study to improve primary and secondary prevention of premature MI in the United Arab Emirates, a high-income country in the MENA region.

Sex, drugs, risk and resilience: analysis of data from the Canadian Health Behaviour in School-aged Children (HBSC) study

Background

Risk-taking behaviour among adolescents, particularly those experiencing childhood adversities, can predispose to injury, unwanted pregnancy, long-term morbidity and death. Resilience, i.e. adapting to threats and thriving, has rarely been examined as a protective factor for adolescent risk-taking. We studied whether the malleable traits of empathy, confidence, self-control and optimism, all markers of resilience, align with decreased risk-taking despite adversity, among 11-15 year olds.

Methods

From responses of 22 643 Canadian youth to the Health Behaviour in School-aged Children (2014) survey we validated a five-item resilience scale. Using regression analyses, this scale and a single measure of self-control were considered as potential protective factors for a composite measure of risk-taking behaviour and of initiation of sexual activity before age 14.

Results

There was a dose-dependent association between greater resilience and diminished risk-taking for boys and, even more so, among girls. This relationship remained significant after controlling for family and social support, implying that greater resilience may override the detrimental impact of childhood adversity on risk-taking. The least resilient youth were most likely to report early sexual activity, although this relationship was not linear. Generally, the impact of self-control on risk-taking was not statistically significant, perhaps because of shortcomings of the self-control indicator.

Conclusion

Brief screening protocols can identify assets that protect against risk-taking behaviours among adolescents. The malleable nature of these traits offers primary care providers and public health personnel a novel and effective route to decreasing adolescent risk-taking and fostering future health.

Cardiovascular mortality attributable to dietary risk factors in 51 countries in the WHO European Region from 1990 to 2016: a systematic analysis of the Global Burden of Disease Study

This study was performed to highlight the relationship between single dietary risk factors and cardiovascular diseases (CVDs) in the WHO European Region. We used the comparative risk assessment framework of the Global Burden of Disease Study to estimate CVD mortality attributable to diet; comprising eleven forms of CVDs, twelve food and nutrient groups and 27 risk-outcome pairs in four GBD regions including 51 countries by age and sex between 1990 and 2016. In 2016, dietary risks were associated with 2.1 million cardiovascular deaths (95% uncertainty interval (UI), 1.7-2.5 million) in the WHO European Region, accounting for 22.4% of all deaths and 49.2% of CVD deaths. In terms of single dietary risks, a diet low in whole grains accounted for approximately 429,000 deaths, followed by a diet low in nuts and seeds (341,000 deaths), a diet low in fruits (262,000 deaths), a diet high in sodium (251,000 deaths), and a diet low in omega-3 fatty acids (227,000 deaths). Thus, with an optimized, i.e. balanced diet, roughly one in every five premature deaths could be prevented. Although age-standardized death rates decreased over the last 26 years, the absolute number of diet-related cardiovascular deaths increased between 2010 and 2016 by 25,600 deaths in Western Europe and by 4300 deaths in Central Asia. In 2016, approximately 601,000 deaths (28.6% of all diet-related CVD deaths) occurred among adults younger than 70 years. Compared to other behavioural risk factors, a balanced diet is a potential key lever to avoid premature deaths.
