The Association Between State Characteristics and Latinx People's Treated Hypertension in Established and New Latinx Destination States: A Multilevel Analysis.

This study sought to quantify the contributions of state-level factors including income inequality, state's legislature political control, and Medicaid expansion in new and established Latinx destination states on Latinx individuals' treated hypertension. Mixed-effects logistic regression analyses were conducted to analyze 2017 Behavioral Risk Factor Surveillance System data from 7524 Latinx adults nested within 39 states. Overall, 70% reported being pharmacologically treated for hypertension, and 66% resided in established destination states. Compared with Latinx people in established destination states, Latinx people in new destinations had lower odds of having treated hypertension (odds ratio [OR] = 0.72, 95% CI = 0.54-0.95). Within established Latinx destinations, the odds of treated hypertension were lower in states where legislatures expanded Medicaid than in states that did not expand Medicaid (OR = 0.84, 95% CI = 0.79-0.89). However, after controlling for the effects of individual-level factors, this association was no longer statistically significant. In new Latinx destination states, Medicaid expansion, legislatures' political control, and income inequality were not associated with treated hypertension. The study results highlight the importance of considering both individual- and state-level factors, as the interplay of such factors could hinder the successful implementation of cardiovascular risk reduction interventions.

Community and Organizational Readiness to Adopt a Physical Activity Intervention in Micropolitan Settings.

BACKGROUND: Assessing community and organizational readiness is key to successfully implementing programs. The purpose of this study was to assess the baseline readiness of micropolitan communities to adopt an evidence-based physical activity (PA) intervention by exploring three dimensions: (1) attitudes and current efforts toward prevention, (2) community and organizational climate that facilitates (or impedes) change, and (3) capacity to implement change. METHOD: Data were collected from community leaders in 14 communities through an online survey in June 2021 (n = 149). Data were analyzed in aggregate using descriptive statistics for multiple-choice responses and content analysis for open ended responses. One-way repeated analyses of variance were used to compare mean score differences. RESULTS: In reference to their attitudes prior to the pandemic, respondents said that addressing PA was "somewhat a priority" in their professional positions (M = 2.01, SD = 0.94), their organizations (M = 2.08, SD = 0.91), and their communities (M = 2.28, SD = 0.88). Current PA efforts included statewide initiatives, community sponsored events/clubs, and youth sports leagues. The community climate included both PA facilitators (mainly outdoor PA resources) and barriers (cost, lack of social services, and an unsupportive PA environment). Individual-level capacity (M = 2.94; SD = 1.21) to adopt a PA program was regarded lower than the community's capacity (M = 3.95; SD = 0.82), and perceptions of capacity at the community level improved even more if technical assistance (M = 3.96; SD = 0.84) or financial support (M = 4.12; SD = 0.80) were provided. CONCLUSION: Readiness varied by dimension, suggesting the need for tailored implementation supports including technical assistance and financial support.

The "dirty work" of last responders: Occupational stigma risk and protective factors.

Last responders constitute an occupational category that includes all those who are involved in the postmortem care of deceased persons and their families. The work of last responders is often considered "dirty work" and, as a result, stigmatized. Last responders are aware of this stigma, and stigma consciousness has been associated with negative health outcomes. Despite the wide acknowledgment of stigma among last responders, specific risk, or protective factors for experiencing stigma have not been investigated. This paper aims to identify determinants of stigma among last responders in the United States. The data for this study were obtained from a national cross-sectional survey of last responders. The survey included a measure of stigma and multiple sociodemographic characteristics. A hurdle model was used to assess the association between the characteristics of last responders and their perceived stigma. Respondents were predominantly male (55.1%), White non-Hispanic (90.2%), and employed full-time (96%). Seventy-seven percent reported having experienced at least one form of occupation-related stigma. There was no significant association between the experience of stigma and any socio-demographic variables. The experience of stigma is nearly ubiquitous among last responders->75% of last responders in the sample experienced at least one form of stigma. Another aspect of its ubiquitous nature is the lack of evidence that stigma was experienced differentially across sex, race/ethnicity, employment type, and length of years as a last responder. Interventions are needed to decrease stigma among last responders and to support last responders in managing the consequences of the stigma they experience.

Ignored and distressed: a cross-sectional study of the impact of COVID-19 on last responders.

BACKGROUND: Last responders constitute an occupational category that includes all those that are involved in the postmortem care of deceased persons and their families. Last responders are exposed to several categories of work-related stressors that affect their health and well-being. COVID-19 exacerbated these stressors. Research to understand the consequences of COVID-19 on the health and wellbeing of last responders is nascent. This study aimed to assess COVID-19 related stress, coping and wellbeing among last responders in the United States. METHODS: We conducted a national cross-sectional survey of last responders in July through September of 2020. The survey measured wellbeing, stress, coping, and stigma; COVID-19 experiences, and socio-demographics. A ridge regression model was fit for the outcome variables. RESULTS: Analysis was conducted on 366 respondents from 43 states. Respondents were male (55.4%), age 50 + (57.4%), and White non-Hispanic (90.3%); 54% reported moderate-high stress and 41% endorsed mild-severe anxiety. Seventy-seven percent had experienced at least one form of stigma related to their occupation. Variables associated with higher perceived stress and anxiety included gender (female), shorter length of employment, perceiving a higher impact from COVID-19 on everyday life, and increased perceived stigma. CONCLUSIONS: Last responders are a critical part of the health care system. Throughout this pandemic, last responders have been frequently ignored and not prioritized for protection and support. Interventions to support last responders cope with stress, and to decrease anxiety are urgently needed. There is also a critical need to challenge community stigma towards last responders.

Waterpipe tobacco smoking (WTS) control policies: global analysis of available legislation and equity considerations.

INTRODUCTION: The Framework Convention on Tobacco Control (FCTC) offers guidance on evidence-based policies to reduce tobacco consumption and its burden of disease. Recently, it has provided guidance for alternative tobacco products, such as the waterpipe. Waterpipe tobacco smoking (WTS) is prevalent worldwide and policies to address it need to take into consideration its specificities as a mode of smoking. In parallel, a growing body of literature points to the potential of evidence-based tobacco control policies to increase health inequities. This paper updates a previous global review of waterpipe tobacco policies and adds an equity lens to assess their impact on health inequities. METHODS: We reviewed policies that address WTS in 90 countries, including 10 with state-owned tobacco companies; 47 were included in our final analysis. We relied primarily on the Tobacco-Free Kids organisation's Tobacco Control Laws website, providing access to tobacco control laws globally. We categorised country tobacco policies by the clarity with which they defined and addressed waterpipe tobacco in relation to nine FCTC articles. We used the PROGRESS (Place of residence, Race/ethnicity/culture/language, Occupation, Gender/sex, Religion, Education, Socioeconomic status and Social capital) framework for the equity analysis, by reviewing equity considerations referenced in the policies of each country and including prevalence data disaggregated by equity axis and country where available. RESULTS: Our results revealed very limited attention to waterpipe policies overall, and to equity in such policies, and highlight the complexity of regulating WTS. We recommend that WTS policies and surveillance centre equity as a goal. CONCLUSIONS: Our recommendations can inform global policies to reduce WTS and its health consequences equitably across population groups.

High-School Students Rarely Use E-Cigarettes Alone: A Sociodemographic Analysis of Polysubstance Use Among Adolescents in the United States.

INTRODUCTION: Most adolescents reporting e-cigarette use have also used combustible tobacco; however, the extent to which they use other substances is less clear. This study assessed e-cigarette use with tobacco, alcohol, or cannabis and quantified the risk of polysubstance use among adolescents overall and by sociodemographic characteristics. AIMS AND METHODS: Using 2017 Youth Behavioral Risk Factor Surveillance System data from adolescents (grades 9-12) with complete substance use information (n = 11 244), we examined e-cigarette poly-use status (none [referent], e-cigarettes only, or e-cigarettes + other substances). We estimated the prevalence of substance use and modeled odds of e-cigarette use, alone or with other substances, by several sociodemographic characteristics. Analyses were completed in Stata version 15.1 using survey procedures to account for the complex survey design. RESULTS: Approximately 12% of adolescents reported past 30-day e-cigarette use. Almost all (93%) e-cigarette users also reported other substance use; alcohol appeared most frequently in combinations. Odds of e-cigarette single use and e-cigarette poly-use (vs. no use) were higher for males and adolescents with lower grades (odds ratios [ORs] = 1.44-2.31). Racial/ethnic minorities had lower odds of e-cigarette poly-use than White peers (ORs = 0.18-0.61), and bisexual (vs. straight) adolescents were more likely to be e-cigarette poly-users (OR = 1.62). E-cigarette use increased from 9th grade (7%) to 12th grade (16%). CONCLUSIONS: Polysubstance use is highly prevalent among adolescents who use e-cigarettes. Therefore, e-cigarette screening should include the assessment of other substances, especially alcohol. Early and comprehensive prevention efforts to reduce e-cigarette and other substance use could have a substantial beneficial impact on population health over time. IMPLICATIONS: This study extends knowledge about e-cigarette use among adolescents by exploring its use with alcohol, cannabis, and other tobacco products. We found that e-cigarettes were very rarely used alone, and our analysis identified several sociodemographic factors associated with greater odds of e-cigarette polysubstance use. In response, we recommend that prevention interventions address multiple substances concurrently, screen repeatedly to detect new initiation as age increases, focus on e-cigarette use as a less stigmatized entry point to discussions of substance use, and target priority population subgroups.

'When I smoked it, it was like a slap in the face but it felt really good': exploring determinants of midwakh use among young adults in Lebanon.

BACKGROUND: Dokha ('dizziness' in English) is a type of alternative tobacco product (ATP) increasing in popularity in the Arab world; and smoked in a pipe called a midwakh. Midwakh use is common among nationals in the United Arab Emirates (UAE); yet, evidence indicates its spread among expats in the UAE as well as beyond the UAE. Research on midwakh use is nascent, and no qualitative research has been published. This paper explored the context and determinants of midwakh use among young adults in Lebanon using qualitative methods. METHODS: We conducted four focus group discussions with 18 midwakh ever smokers aged 18-25 years in Lebanon. Discussions were recorded, transcribed and thematically analysed using the Pragmatics, Attraction, Communication, Expectations framework. RESULTS: 'Pragmatics' was evident in participants' comments about availability of a supply of dokha. For 'attraction', participants described why they prefer midwakh smoking and compared it to other ATPs. Regarding communication, participants shared terms used to describe their use of midwakh (eg, 'buzz'/taking a hit). Participants also described expectations from smoking midwakh, including stress relief. CONCLUSION: Midwakh smoking is appealing to young adults due to factors such as the 'buzz', perceived harm reduction, stress relief and its ability to satisfy nicotine craving with small amounts of tobacco. As a result, despite experiencing negative effects on first use, young adults choose to continue to use midwakh, and find it hard to quit. These results have implications for prevention and control of midwakh smoking among young adults. Framework Convention on Tobacco Control guidance documents to address ATPs are critically needed to prevent the global spread of yet another tobacco product.

A call to advance and translate research into policy on governance, ethics, and conflicts of interest in public health: the GECI-PH network.

Efforts to adopt public health policies that would limit the consumption of unhealthy commodities, such as tobacco, alcohol and ultra-processed food products, are often undermined by private sector actors whose profits depend on the sales of such products. There is ample evidence showing that these corporations not only try to influence public health policy; they also shape research, practice and public opinion. Globalization, trade and investment agreements, and privatization, amongst other factors, have facilitated the growing influence of private sector actors on public health at both national and global levels. Protecting and promoting public health from the undue influence of private sector actors is thus an urgent task. With this backdrop in mind, we launched the "Governance, Ethics, and Conflicts of Interest in Public Health" Network (GECI-PH Network) in 2018. Our network seeks to share, collate, promote and foster knowledge on governance, ethical, and conflicts of interest that arise in the interactions between private sectors actors and those in public health, and within multi-stakeholder mechanisms where dividing lines between different actors are often blurred. We call for strong guidance to address and manage the influence of private sector actors on public health policy, research and practice, and for dialogue on this important topic. Our network recently reached 119 members. Membership is diverse in composition and expertise, location, and institutions. We invite colleagues with a common interest to join our network.

"Taking Up a New Problem": Context and Determinants of Pod-Mod Electronic Cigarette Use Among College Students.

In this article, we explore the context and determinants of pod-mod electronic cigarette (ECIG) use among college students aged 18 to 24 in the United States. We conducted semi-structured interviews with 55 students (M age = 20 years, 56% female, 65% White) on three campuses in the Northwest, Midwest, and Southeast. We performed a thematic analysis. Students described ECIG use by peers, increased ECIG exposure and prevalence in college, and school-related stress as reasons for vaping. Pod-mod features such as convenience, design, easy concealment, and flavors made vaping more appealing. Negative aspects of vaping included addiction, cost, and possible health consequences. Most viewed vaping as a college behavior and intended to quit after graduation. Our results show that the college environment plays a major role in young adult ECIG use. These findings can inform the development of targeted interventions to prevent and control uptake of ECIGs by young adults.

"I Like to Try My Hardest to Keep My Small Family Together": Housing as a Key Resource for Academic Success of Pregnant and Parenting College-Aged Students.

Pregnant and/or parenting students (PPS) face unique challenges to attending college. The prevalence of housing insecurity may be higher among college PPS. Adding to the limited research in this area, our study explores how housing could be a barrier to attending and maintaining academic success in college for PPS. We partnered with a Midwestern community college (CC) to conduct the study, which consisted of (1) an environmental scan of in-state collegiate housing programs available to PPS, (2) an online survey among PPS attending the partner CC, and (3) key informant interviews with providers at agencies serving PPS and high school PPS planning to attend college. Eight of the 18 institutions we identified from our environmental scan offered family housing. Populations most often addressed were married students (56%), families (39%), and single parents (28%). Out of 22 responses from our online survey, about a third of PPS disagreed or strongly disagreed that they felt satisfied with housing support provided by the partnering CC and that housing options offered were family friendly. PPS perceived affordability, proximity to campus and to their children's school, on-site day care, and amenities as important aspects of housing. Key informant participants (n = 9 interviews) described social support, PPS-specific housing, and access to services as important to college attendance. Community college efforts to meet the needs of PPS must consider the unique barriers PPS face to finding affordable and stable housing. Collaborating with local agencies that offer services for PPS is one approach to ensuring their academic success.

'Most at risk' for COVID19? The imperative to expand the definition from biological to social factors for equity.

First recognized in December 2019, the Coronavirus Disease 2019 (COVID19) was declared a global pandemic by the World Health Organization on March 11, 2020. To date, the most utilized definition of 'most at risk' for COVID19 morbidity and mortality has focused on biological susceptibility to the virus. This paper argues that this dominant biomedical definition has neglected the 'fundamental social causes' of disease, constraining the effectiveness of prevention and mitigation measures; and exacerbating COVID19 morbidity and mortality for population groups living in marginalizing circumstances. It is clear - even at this early stage of the pandemic - that inequitable social conditions lead to both more infections and worse outcomes. Expanding the definition of 'most at risk' to include social factors is critical to implementing equitable interventions and saving lives. Prioritizing populations with social conditions is necessary for more effective control of the epidemic in its next phase; and should become standard in the planning for, and prevention and mitigation of all health conditions. Reversing disparities and health inequities is only possible through an expansion of our 'most-at-risk' definition to also include social factors.

Lessons learned in the provision NCD primary care to Syrian refugee and host communities in Lebanon: the need to 'act locally and think globally'.

BACKGROUND: Prevention and control of non-communicable diseases (NCDs) remain inadequate in resource-scarce countries, particularly in conflict situations. This paper describes a multicomponent intervention for management of hypertension and diabetes among older adult Syrian refugees and the Lebanese host community and reflects on challenges for scaling up NCD integration into primary care in humanitarian situations. METHODS: Using a mixed method approach, the study focused on monitoring and evaluation of the three components of the intervention: healthcare physical facilities and documentation processes, provider knowledge and guideline-concordant performance, and refugee and host community awareness. RESULTS: Findings revealed overall high compliance of healthcare workers with completing data collection forms. Their knowledge of basic aspects of hypertension/diabetes management was adequate, but diagnosis knowledge was low. Patients and healthcare providers voiced satisfaction with the program. Yet, interruptions in medicines' supplies and lapses in care were perceived by all study groups alike as the most problematic aspect of the program. CONCLUSIONS: Our intervention program was aligned with internationally agreed-upon practices, yet, our experiences in the field point to the need for more 'local testing' of modified interventions within such contexts. This can then inform 'thinking globally' on guidelines for the delivery of NCD care in crisis settings.

Building Emotional Resilience in Youth in Lebanon: a School-Based Randomized Controlled Trial of the FRIENDS Intervention.

In Lebanon, approximately one in four adolescents suffers from a psychiatric disorder. Alarmingly, 94% of adolescents with a mental disorder have not sought any treatment. This study assessed the effectiveness of an evidence-based school-based universal mental health intervention (the FRIENDS program) in reducing depression and anxiety symptoms in middle school students in Lebanon. A total of 280 6th graders aged 11-13 years were recruited from 10 schools in Beirut. Schools were matched on size and tuition and randomly assigned to intervention or control groups. The FRIENDS program was translated into Arabic, adapted, and then implemented by trained mental health professionals during 10 classroom sessions over 3 months. We assessed sociodemographic and relevant psychological symptoms by self-report, using the Scale for Childhood Anxiety and Related Disorders (SCARED), Mood and Feelings Questionnaire (MFQ), and Strengths and Difficulties Questionnaire (SDQ), at baseline. We re-administered these scales at 3 months post-intervention. There was a significant time × group interaction for the SDQ emotional score (p = 0.011) and total MFQ score (p = 0.039) indicating significant improvement in depressive and emotional symptoms in the intervention group. Subgroup analysis by gender showed a significant time × group interaction for the total SCARED score (p = 0.025) in females but not in males (p = 0.137), consistent with a reduction of anxiety symptoms in this stratum of the intervention group as compared with the control group. The FRIENDS program was effective in reducing general emotional and depressive symptoms among middle school students in this Lebanese study population. This intervention provides an opportunity for promoting mental health in Lebanese schools and reducing the treatment gap in mental health care.

Implementing Community-Based Participatory Research with Communities Affected by Humanitarian Crises: The Potential to Recalibrate Equity and Power in Vulnerable Contexts.

Worldwide, over 70.8 million people are forcibly displaced from their homes as a result of persecution, conflict, violence, or human rights violation. In humanitarian crises, protection and the provision of basic needs are often prioritized. Research may be seen as opportunistic. However, without documenting and researching humanitarian responses, knowledge is not shared and does not accumulate, limiting the application of evidence-based interventions where they are most needed. Research in humanitarian crises is complex, both ethically and methodologically. Community-engaged research, and specifically community-based participatory research (CBPR), can address some of the challenges of research in these settings. Using case studies of research we have conducted with communities affected by humanitarian crises, we highlight challenges and opportunities of the application of the ten core principles of CBPR in humanitarian settings. Despite some challenges and barriers, CBPR is a highly effective approach to use when engaging these populations in research. We argue that the application of CBPR in these settings has the potential to recalibrate the scales of equity and power among vulnerable populations.

Youth Participatory Approaches and Health Equity: Conceptualization and Integrative Review.

There is an array of youth participatory approaches relevant to health equity efforts in community psychology, adolescent health, youth development, and education. While they share some commonalities, they also reflect important distinctions regarding key processes and intended level of impact. Here, we consider the following: (a) youth-led participatory action research (YPAR), (b) youth organizing (YO), (c) youth-led planning, (d) human-centered design, (e) participatory arts, and (f) youth advisory boards. Informed by community psychology theories on empowerment and levels of change and social epidemiology frameworks that focus on the social determinants of health inequities, we aim to promote greater clarity in the conceptualization, implementation, and evaluation of youth participatory approaches; frame the "landscape" of youth participatory approaches and their similarities and differences; present an integrative review of the evidence regarding the impact of youth participatory approaches; and describe several illustrative cases so as to consider more deeply how some youth participatory approaches aim to influence the social determinants of health that lead to the physical embodiment of health inequities. We conclude by identifying areas of future policy- and practice-relevant research for advancing youth participation and health equity.

Bullying Victimization and Use of Substances in High School: Does Religiosity Moderate the Association?

Alcohol, tobacco and other drug use continue to pose serious public health concerns among youth. Bullying victimization has been identified as a risk factor and religiosity a protective factor for adolescent substance use. No previous research has examined the potential moderating role of religiosity. We explore the association between bullying victimization and substance use in adolescents with low and high levels of religiosity. A cross-sectional survey was conducted with a representative sample of high school students in greater Beirut. Binary and multinomial logistic models were used, adjusting for demographics, and stratified by level of religiosity. Of the 986 students responding to the survey, 65% were females; 48% had experienced some form of bullying; and 52% self-rated as low in religiosity. Between 10 and 30% were current users of alcohol or tobacco. Students of lower religiosity levels who had been bullied were more likely to use substances than those who self-rated as high religiosity. Religiosity may be a potential moderator of the association between being bullied and substance use, but the exact mechanisms and underlying reasons need further investigation.

Participatory praxis as an imperative for health-related stigma research.

BACKGROUND: Participatory praxis is increasingly valued for the reliability, validity, and relevance of research results that it fosters. Participatory methods become an imperative in health-related stigma research, where the constitutive elements of stigma, healthcare settings, and research each operate on hierarchies that push those with less social power to the margins. DISCUSSION: Particularly for people who are stigmatized, participatory methods balance the scales of equity by restructuring power relationships. As such, participatory praxis facilitates a research process that is responsive to community-identified priorities and creates community ownership of the research, catalyzing policy change at multiple levels and foregrounds, and addresses risks to communities from participating in research. Additionally, through upholding the agency and leadership of communities facing stigma, it can help to mitigate stigma's harmful effects. Health-related stigma research can reduce the health inequities faced by stigmatized groups if funders and institutions require and reward community participation and if researchers commit to reflexive, participatory practices. A research agenda focused on participatory praxis in health-related stigma research could stimulate increased use of such methods. CONCLUSION: For community-engaged practice to become more than an ethical aspiration, structural changes in the funding, training, publishing, and tenure processes will be necessary.

"There Is Zero Regulation on the Selling of Alcohol": The Voice of the Youth on the Context and Determinants of Alcohol Drinking in Lebanon.

Alcohol-related research from the Arab world has rarely touched on the experiences or views of Arab adolescents. In this article, we present an in-depth analysis of youth alcohol drinking patterns and determinants derived from focus group discussions completed with more than 100 Lebanese high school/vocational students (15-19 years). The social ecology of alcohol use framework guided our research and analysis. Findings reveal that alcohol drinking is perceived as a pervasive and serious public health problem, triggered by a complex web of social relations, and facilitated by lax policies. Recommendations to curb heavy/harmful alcohol drinking among adolescents include regulating the role of alcohol industry, providing alternative recreational spaces/pass-times, educating about alcohol-related harms, and promoting more research on alcohol and its harms. Findings confirm the social ecology of alcohol use framework, and suggest the addition of the macro level of influence to this model, namely, a comprehensive alcohol harm reduction policy.

Global burden of diseases, injuries, and risk factors for young people's health during 1990-2013: a systematic analysis for the Global Burden of Disease Study 2013.

BACKGROUND: Young people's health has emerged as a neglected yet pressing issue in global development. Changing patterns of young people's health have the potential to undermine future population health as well as global economic development unless timely and effective strategies are put into place. We report the past, present, and anticipated burden of disease in young people aged 10-24 years from 1990 to 2013 using data on mortality, disability, injuries, and health risk factors. METHODS: The Global Burden of Disease Study 2013 (GBD 2013) includes annual assessments for 188 countries from 1990 to 2013, covering 306 diseases and injuries, 1233 sequelae, and 79 risk factors. We used the comparative risk assessment approach to assess how much of the burden of disease reported in a given year can be attributed to past exposure to a risk. We estimated attributable burden by comparing observed health outcomes with those that would have been observed if an alternative or counterfactual level of exposure had occurred in the past. We applied the same method to previous years to allow comparisons from 1990 to 2013. We cross-tabulated the quantiles of disability-adjusted life-years (DALYs) by quintiles of DALYs annual increase from 1990 to 2013 to show rates of DALYs increase by burden. We used the GBD 2013 hierarchy of causes that organises 306 diseases and injuries into four levels of classification. Level one distinguishes three broad categories: first, communicable, maternal, neonatal, and nutritional disorders; second, non-communicable diseases; and third, injuries. Level two has 21 mutually exclusive and collectively exhaustive categories, level three has 163 categories, and level four has 254 categories. FINDINGS: The leading causes of death in 2013 for young people aged 10-14 years were HIV/AIDS, road injuries, and drowning (25·2%), whereas transport injuries were the leading cause of death for ages 15-19 years (14·2%) and 20-24 years (15·6%). Maternal disorders were the highest cause of death for young women aged 20-24 years (17·1%) and the fourth highest for girls aged 15-19 years (11·5%) in 2013. Unsafe sex as a risk factor for DALYs increased from the 13th rank to the second for both sexes aged 15-19 years from 1990 to 2013. Alcohol misuse was the highest risk factor for DALYs (7·0% overall, 10·5% for males, and 2·7% for females) for young people aged 20-24 years, whereas drug use accounted for 2·7% (3·3% for males and 2·0% for females). The contribution of risk factors varied between and within countries. For example, for ages 20-24 years, drug use was highest in Qatar and accounted for 4·9% of DALYs, followed by 4·8% in the United Arab Emirates, whereas alcohol use was highest in Russia and accounted for 21·4%, followed by 21·0% in Belarus. Alcohol accounted for 9·0% (ranging from 4·2% in Hong Kong to 11·3% in Shandong) in China and 11·6% (ranging from 10·1% in Aguascalientes to 14·9% in Chihuahua) of DALYs in Mexico for young people aged 20-24 years. Alcohol and drug use in those aged 10-24 years had an annual rate of change of >1·0% from 1990 to 2013 and accounted for more than 3·1% of DALYs. INTERPRETATION: Our findings call for increased efforts to improve health and reduce the burden of disease and risks for diseases in later life in young people. Moreover, because of the large variations between countries in risks and burden, a global approach to improve health during this important period of life will fail unless the particularities of each country are taken into account. Finally, our results call for a strategy to overcome the financial and technical barriers to adequately capture young people's health risk factors and their determinants in health information systems.
