An unfinished agenda on adolescent health: Opportunities for interventions

Focusing on colorectal cancer in young adults (Review)

Colorectal cancer (CRC) ranks as the third leading cause of cancer-related mortality worldwide. Recent years have witnessed an increase in the incidence of CRC among adults <50 years old on a global scale. The increased incidence is associated with several modifiable risk factors, including obesity, type II diabetes, physical inactivity and frequent antibiotic use. In younger individuals, haematochezia and abdominal pain are the most common symptoms, predominantly affecting the left-side colon. While certain cases of early-onset CRC (eoCRC) are associated with a genetic predisposition, the majority result from sporadic mutations in the genes APC, KRAS, BRAF and TP53, which trigger uncontrolled cell proliferation and tumour formation. Colorectal carcinogenesis involves three major pathways: The chromosomal instability (CIN), microsatellite instability and CpG island methylator phenotype pathways. Dysregulation of the CIN pathway accounts for 85% of sporadic cases of eoCRC. Notably, eoCRC exhibits a distinctive molecular profile, characterized by a decreased prevalence of BRAF mutations, an increased prevalence of KRAS mutations and LINE-1 hypomethylation, and involvement of the Microsatellite and Chromosomal Stable pathway. Prevention strategies for eoCRC primarily centre on lifestyle modifications and the development of screening programs targeting younger populations. Further exploration into the molecular mechanisms involved in the identification of novel risk factors associated with eoCRC is imperative. These efforts, in conjunction with the development of specific screening strategies, hold the potential to reduce morbidity and mortality in the future.

The effect of solution-focussed education and counselling on problematic internet usage, sleep quality and school achievement: A randomized controlled trial

AIM

The aim of this study was to determine the effects of solution-focussed education and counselling on problematic internet usage, sleep quality and school achievement.

METHODS

This randomized controlled trial was conducted between January - December 2016 with 44 adolescents who participated in a solution-focussed intervention to address their problematic internet usage and poor sleep quality. After the intervention, the teens were followed up for 6 months to measure problematic Internet usage, sleep quality and school achievement using the Internet Addiction Test, Pittsburg Sleep Quality Index, Parent-Child Internet Addiction Scale and the students' end-of-term school grades. Data were analysed in Statistical Package for the Social Sciences programme using Chi-square test, Independent t test, Man-Whitney U test, Friedman test and Spearman correlation analysis.

RESULTS

The median Internet Addiction Test and Pittsburg Sleep Quality Index scores of the adolescents in the intervention group were significantly lower than those of the controls (P < 0.05), and there was a positive and moderate association between problematic Internet usage and sleep quality in both groups after the follow-up (r = 0.537, P = 0.010; r = 0.576 P = 0.005).

CONCLUSION

The education and counselling intervention decreased problematic Internet usage and increased sleep quality. There was also an improvement in school achievement, but the difference was not significant.

Needs, Barriers and Facilitators of Adolescents Participating in a Lifestyle Promotion Program in Oncology: Stakeholders, Adolescents and Parents’ Perspective

Treatments for adolescent cancer can cause debilitating side effects in the short- and long-term such as nausea and malnutrition but also cardiometabolic disturbances. Although the risk for cardiometabolic complications is greater for adolescents with cancer than younger ones, adolescents typically respond poorly to family-oriented health promotion programs. This study aims to assess the needs, barriers and facilitators to healthy lifestyle promotion interventions for adolescents with cancer and how to best adapt these interventions for them. Interviews were held with adolescents treated for cancer (n = 9) and parents (n = 6), focus groups were conducted with stakeholders working in oncology (n = 12) and self-report questionnaires were sent to stakeholders involved in a health promotion intervention (n = 6). At the time of interview, mean age of adolescent participants (40% female) was 17.0 ± 1.9 years (mean age at diagnosis: 14.6 ± 1.6 years). Verbatim and responses to questionnaires were coded and analyzed using qualitative methods. Stakeholder stated that adolescents with cancer need to access activities adapted to their age, to communicate with peers going through a similar experience, and to preserve their schooling and friendships. Barriers to intervention reported by adolescents, parents and stakeholders include lack of motivation, schedule conflicts, fatigue and treatment side effects. Some of the barriers mentioned by adolescents and parents include pain, post-surgery problems, school, physical deconditioning, and lack of time. Facilitators mentioned by adolescents and parents comprise trust in stakeholders’ expertise, personalized approaches, scheduling flexibility. Stakeholders recommended to build trust in the relationship, favoring non-moralizing teachings, adapt interventions to adolescents’ limited attention span and avoiding the use of long-term health benefits as a motivator.

Participatory Action Research for Adolescent Sexual and Reproductive Health: A Scoping Review

Introduction: Youth-friendly sexual and reproductive health (SRH) interventions are essential for the health of adolescents (10–19 years). Co-designing is a participatory approach to research, allowing for collaboration with academic and non-academic stakeholders in intervention development. Participatory action research (PAR) involves stakeholders throughout the planning, action, observation, and reflection stages of research. Current knowledge indicates that co-producing SRH interventions with adolescents increases a feeling of ownership, setting the scene for intervention adoption in implementation settings. Objectives: This scoping review aims to understand the extent of adolescents’ participation in PAR steps for co-designed SRH interventions, including the barriers and facilitators in co-designing of SRH intervention, as well as its effectiveness on adolescents’ SRH outcomes. Methods: Database searching of PubMed, Medline, Embase, CINAHL, Scopus, Web of Science, Google Scholar, and organisational websites was performed, identifying 439 studies. Results: Upon screening, 30 studies (published between 2006–2021) met the inclusion criteria. The synthesis identified that adolescents were involved in the planning and action stages of the interventions, but not in the observation and reflection stages. Although the review identified the barriers and facilitators for co-designing SRF interventions, none of the included studies reported on the effectiveness of co-designing SRH interventions with adolescents; therefore, meta-analysis was not performed. Conclusions: While no specific outcome of the interventions was reported, all papers agreed that adolescent co-designing in ASRH interventions should occur at all stages to increase understanding of local perceptions and develop a successful intervention.

Early Nutritional Intervention to Promote Healthy Eating Habits in Pediatric Oncology: A Feasibility Study

This study aims to describe the feasibility of a nutritional intervention that promotes healthy eating habits early after cancer pediatric diagnosis in patients and their parents. Participants were recruited 4 to 12 weeks after cancer diagnosis as part of the VIE study. The one-year nutritional intervention included an initial evaluation and 6 follow-up visits every 2 months with a registered dietician. The feasibility assessment included rates of retention, participation, attendance, completion of study measures, and participants' engagement. A preliminary evaluation of the intervention's impact on the participants' dietary intakes was conducted. A total of 62 participants were included in the study (51.6% male, mean age = 8.5 years, mean time since diagnosis = 13.2 weeks). The retention and attendance rates were 72.6% and 71.3%, respectively. Attendance to follow-up visits declined over time, from 83.9% to 48.9%. A majority of participants had high participation (50.8%) and high engagement (56.4%). Measures of body-mass-index or weight-for-length ratio and dietary 24-h recalls were the procedures with the highest completion rates. Participants with refractory disease or relapse were less likely to complete the intervention. Post-intervention, participants (n = 21) had a lower sodium intake compared to the initial evaluation. These results suggest that a nutritional intervention that involves patients and parents early after a pediatric cancer diagnosis is feasible.

Non-communicable diseases among adolescents: current status, determinants, interventions and policies

BACKGROUND

Addressing non-communicable disease (NCDs) is a global priority in the Sustainable Development Goals, especially for adolescents. However, existing literature on NCD burden, risk factors and determinants, and effective interventions and policies for targeting these diseases in adolescents, is limited. This study develops an evidence-based conceptual framework, and highlights pathways between risk factors and interventions to NCD development during adolescence (ages 10-19 years) and continuing into adulthood. Additionally, the epidemiologic profile of key NCD risk factors and outcomes among adolescents and preventative NCD policies/laws/legislations are examined, and a multivariable analysis is conducted to explore the determinants of NCDs among adolescents and adults.

METHODS

We reviewed literature to develop an adolescent-specific conceptual framework for NCDs. Global data repositories were searched from Jan-July 2018 for data on NCD-related risk factors, outcomes, and policy data for 194 countries from 1990 to 2016. Disability-Adjusted Life Years were used to assess disease burden. A hierarchical modeling approach and ordinary least squares regression was used to explore the basic and underlying causes of NCD burden.

RESULTS

Mental health disorders are the most common NCDs found in adolescents. Adverse behaviours and lifestyle factors, specifically smoking, alcohol and drug use, poor diet and metabolic syndrome, are key risk factors for NCD development in adolescence. Across countries, laws and policies for preventing NCD-related risk factors exist, however those targeting contraceptive use, drug harm reduction, mental health and nutrition are generally limited. Many effective interventions for NCD prevention exist but must be implemented at scale through multisectoral action utilizing diverse delivery mechanisms. Multivariable analyses showed that structural/macro, community and household factors have significant associations with NCD burden among adolescents and adults.

CONCLUSIONS

Multi-sectoral efforts are needed to target NCD risk factors among adolescents to mitigate disease burden and adverse outcomes in adulthood. Findings could guide policy and programming to reduce NCD burden in the sustainable development era.

An exploration of occupational choices in adolescence: A constructivist grounded theory study

BACKGROUND

Adolescence is a critical period within the life course, for developing adult occupational competencies and health behaviours. Few studies have considered how 16-17 year olds choose activities and behaviours from an occupational perspective.

AIM AND OBJECTIVES

To explore how adolescents aged 16-17 years old make choices about their daily occupations to inform a theoretical model of occupational choice.

MATERIALS AND METHODS

About 27 secondary school students aged 16-17 years attended one of six focus groups. Transcripts were analyzed using constructivist grounded theory, informing the iterative development of a theoretical model of occupational choice.

RESULTS

Adolescent occupational choice occurred in response to experiencing needs, and was characterized by 'weighing up' and 'juggling' the following four key domains: 'Appraising values and priorities', 'Interacting with the situational context', 'Exploring skills and occupational repertoire' and 'Considering time factors'. A developing sense of responsibility and autonomy for occupational choices was described, leading to the development of the future occupational self.

CONCLUSIONS AND SIGNIFICANCE

A theory illuminating how adolescents make choices was developed. The theory aligns with existing developmental literature and provides unique insights, from an occupational science perspective, on the conscious process by which adolescents make, develop and adapt choices about the occupations they do considering contextual and individual opportunities and constraints.

School health education program in Pakistan (SHEPP)-a threefold health education feasibility trial in schoolchildren from a lower-middle-income country

BACKGROUND

The school environment plays an essential role in promoting health education and physical activity for children and adolescence, and they are more likely to adapt it into their adulthood. School health education program has been endorsed and emphasized by the World Health Organization has not been implemented in true spirit in Pakistan yet. We aim to test feasibility of threefold health education program in children and its potential efficacy on physical activity and diet and cardiometabolic risk factors by including BP, BMI, and waist circumference.

METHODS

It is a parallel-group feasibility intervention trial. It is being conducted in two schools from lower to middle-income areas, at different locations but having the same school curriculum under the Aga Khan Education Service, Pakistan (AKESP). All children aged 9-11 years enrolled from the schools mentioned above were included. Children with any physical disability were excluded. One school received threefold intervention (focused on children, parents, and teachers) of school health education program in Pakistan (SHEPP) while the other school continued routine activity. Intervention of SHEPP is directed towards educating children, parents, and teachers about healthy behaviors. Children will receive interactive educational sessions and specially designed physical activity sessions. A 3-h health education session focusing on same healthy behaviors as for children will be conducted for both parents and teachers. Primary outcome is feasibility of SHEPP in terms of recruitment, retention, and treatment fidelity. Secondary outcomes are physical activity levels, dietary intake (of fruits, vegetable), and cardiometabolic risk factors (blood pressure, BMI, and waist circumference (WC)). The total number of children recruited were 982 (82.5 %); 505 from school A and 477 from school B and 496 (50.5) were boys.

CONCLUSION

SHEPP is a unique health education program for children as it focuses on children while involving the parents and teachers in the behavior change process. If found feasible and demonstrating potential efficacy on physical activity, dietary behaviors, and cardiometabolic parameters, we will be able to replicate this on a larger scale in public sector schools also.

The effect of solution-focused interviews (SFI) conducted by nurses on middle school adolescents' healthy lifestyles: a quasi-experimental study

AIM

This study aimed at assessing the effect of solution-focused interviews for the promotion of health locus of control and self-efficacy on adolescents' healthy lifestyles.

METHOD

The present study, which was designed as a quasi-experimental study, included pretest and post-test control groups and was conducted in the period between 5 February 2017 and 30 April 2017. The intervention group comprised 28 (n = 28) adolescents from a school, and the control group comprised 30 (n = 30) adolescents from another school. Solution-focused interviews, which included educational information regarding leading a healthy lifestyle as well as cognitive-behavioural interview, were conducted with the adolescents of the intervention group, 1 day per week (nine sessions in total).

RESULTS

In comparison to the control group, adolescents in the intervention group exhibited differences in all the sub-dimensions health promotion scale (p < 0.001).

CONCLUSIONS

These results established the applicability and effectiveness of the programme, such that the health promotion programme could be included in the literature. Moreover, it is anticipated that this programme would be applied in school settings in the future.

An Estimation of the Burden of Sports Injuries among African Adolescents

The extent to which sports injuries contribute to the burden of injury among adolescents in low- and middle-income countries (LMICs) is unknown. The goal of this study was to estimate the incidence of sports injuries among adolescents in Africa. Data from the World Health Organization Global School-Based Student Health surveys were used to estimate the annual number of African adolescents sustaining sports injuries. Gender-stratified injury rates were calculated and applied to every African country’s adolescent population to estimate country-specific and continent-wide injury totals. A total of 21,858 males and 24,691 females from 14 countries were included in the analysis. Country-specific annual sports injury rates ranged from 13.5% to 38.1% in males and 5.2% to 20.2% in females. Weighted average sports injury rates for males and females were 23.7% (95% CI 23.1%–24.2%) and 12.5% (95% CI 12.1%–12.9%), respectively. When these rates were extrapolated to the adolescent populations of the African continent, an estimated 15,477,798 (95% CI 15,085,955–15,804,333) males and 7,943,625 (95% CI 7,689,429–8,197,821) females sustained sports injuries. Our findings suggest that over 23 million African adolescents sustained sports injuries annually. Further work will help to more precisely define the burden of sports injuries in LMICs and the role that surgery can play in mitigating this burden.

Potential interventions targeting adolescent nutrition in Indonesia: a literature review

Objective

The present study aimed to take stock of nutrition interventions that warrant consideration as a minimum package of interventions in Indonesia to improve four key nutrition indicators for adolescents: stunting, thinness, overweight and anaemia.

Design

We conducted a review of the peer-reviewed literature published between 1995 and 2017 on nutrition-specific and nutrition-sensitive interventions that target adolescents in Indonesia. The search to identify studies was conducted in PubMed, Google Scholar and EMBASE, using key search terms. We also explored programmatic and policy documents from the grey literature as they related to adolescents and/or Indonesia. Our search yielded thirty-five peer-reviewed articles and programmatic documents.

Setting

Indonesia.

Subjects

Adolescent girls and boys.

Results

There is very limited evidence on the impact of interventions specifically among adolescents in Indonesia. Nevertheless, findings from our review suggest the minimum package of interventions in Indonesia could include the following nutrition-specifc interventions: (i) iron–folic acid supplements, paired with antihelminths delivered at scale via school-based platforms and through health centres; and (ii) diet counselling and nutrition education provided through school-based platforms, adolescent youth centres/peer education and technology-based platforms. The minimum package could also include the following nutrition-sensitive interventions: (i) improving access to reproductive health services; and (ii) increasing the coverage of interventions designed to increase school attendance.

Conclusions

Programmes and policies targeting adolescent nutrition are relatively new and coverage is low. To improve the nutritional status of this vulnerable population, additional evaluations of adolescent programming and surveillance data on adolescents are needed.

Using Social Media to Target Cancer Prevention in Young Adults: Viewpoint

Focusing on primary cancer prevention can reduce its incidence. Changing health behaviors is critical to cancer prevention. Modifiable cancer risk factors include lifestyle behaviors related to vaccination, physical activity, weight control and maintenance, alcohol consumption, and tobacco use. These health habits are often formed in young adulthood, a life stage which currently intersects with the growing population of digital natives whose childhood occurred in the internet era. Social media is a critical communication medium to reach this population of digital natives. Using a life course perspective, the purpose of this viewpoint paper is to describe the current landscape of nascent research using social media to target cancer prevention efforts in young adults and propose future directions to strengthen the scientific knowledge supporting social media strategies to promote cancer prevention behaviors. Leveraging social media as a health promotion tool is a promising strategy to impact modifiable behavioral risk factors for cancer and warrants further research on developing effective communication strategies in young adults to prevent cancer in the future generations.

Use of Theory to Examine Health Responsibility in Urban Adolescents

The study's purpose was to examine the factors that may influence health responsibility among adolescents. More specifically, this study examined relationships among health responsibility, resilience, neighborhood perception, social support, and health promoting behaviors in adolescents, between the ages of 13 and 18years old. The Health Promotion Model was used as the theoretical framework. This study empirically tested theoretical relationships postulated in the literature between health responsibility and the variables: (a) resilience (b) social support (c) neighborhood perception (d) social support and (e) health promoting behaviors.

DESIGN/METHODS

A correlational study design was used. A convenience sample of 122 adolescents in an urban setting completed questionnaires assessing health responsibility, resilience, social support, neighborhood perception, health promoting behaviors, and a demographic questionnaire. Pearson correlations were used to examine relationships among variables.

RESULTS

A statistically significant relationship was found between health responsibility and healthy promoting behaviors (r=0.733, p<0.001) and between health responsibility and neighborhood perception (r=0.163, p<0.01). No relationships were found between the dependent variable of health responsibility and the independent variables of resilience and social support in this population.

CONCLUSIONS

Study findings help contribute to the body of knowledge regarding the factors that influence health responsibility among urban adolescents to promote adoption and maintenance of healthy behaviors among this population.

PRACTICE IMPLICATIONS

Nurses need to educate adolescents to provide them with a good understanding of the consequences of health behaviors so that they can assess their own risk and make responsible, healthy choices.

Recommendations on Arresting Global Health Challenges Facing Adolescents and Young Adults

BACKGROUND

The health challenges faced by young people are more complex than adults and can compromise their full growth and development. Attention must be paid to the health of this age group, yet adolescents and youth remain largely invisible and often disappear from the major global datasets.

OBJECTIVE

The aim of this paper is to discuss the global health challenges faced by adolescents and youth, global legislations and guidelines pertaining to this particular age group, recommendations to arrest these challenges, and research priorities.

RESULTS

Major direct and indirect global health risks faced by adolescents include early pregnancy and childbirth, femicide, honor killing, female genital mutilation, nutritional habits and choices, social media, and peer pressure. There are no standard legal age cut-offs for adulthood; rather, the age varies for different activities, such as age of consent or the minimum age that young people can legally work, leave school, drive, buy alcohol, marry, be held accountable for criminal action, and make medical decisions. This reflects the fact that the existing systems and structures are focused on either children or adults, with very few investments and interventions directed specifically to young people. Existing legislation and guidelines need transformation to bring about a specific focus on adolescents in the domains of substance use and sexual behaviors, and the capacity for adolescent learning should be exploited through graduated legal and policy frameworks.

CONCLUSION

Sustainable development goals provide an opportunity to target this neglected and vulnerable age group. A multisectoral approach is needed to bring about healthy change and address the challenges faced by adolescents and youth, from modifications at a broader legislative and policy level to ground-level (community-level) implementations.

Sexual and reproductive health needs and risks of very young adolescent refugees and migrants from Myanmar living in Thailand

Background

The very young adolescent (VYA) population age 10–14 years is often neglected in the field of sexual and reproductive health (SRH) research due to the combined sensitivity of the topic and the young age group, resulting in little data about the SRH needs and concerns of VYA. In 2013, the Women’s Refugee Commission (WRC), Johns Hopkins University (JHU), Adolescent and Reproductive Health Network (ARHN) and Karen Youth Organization (KYO) implemented qualitative participatory research to explore the SRH needs and risks of VYA. The study was conducted in Mae Sot town and Mae La refugee camp, both in Thailand, with migrant populations and refugees, respectively.

Methods

A total of 22 focus group discussions (FGD) were conducted with 176 participants. FGD were implemented with girls and boys aged 10–16, and adults in both settings. The FGD with 10–14 year olds included community mapping and photo elicitation interviews. These activities gathered information about their own perspectives, experiences and values regarding SRH, as well as SRH risks. The FGD with 15–16 year olds and adults focused on their perspectives regarding the SRH needs and risks of VYA.

Results

Fourteen (64%) of FGD were conducted in Mae Sot town, and 8 (36%) were conducted in Mae La refugee camp.

Schools, youth centers and religious institutions were identified as key locations for obtaining SRH information. Schools are most promising, but access to schools is unequal between boys and girls. Parents can provide support and education to adolescents if they are supported to do so and if trust and comfort can be built between adolescents and parents around SRH.

Conclusions

To a large degree, the same themes emerged from both locations, in terms of the awareness of body changes and puberty, the centrality of peer influences, and the value of education. These findings call for rigorous study of youth-directed programs and policies that meaningfully involve key influential adults identified by vulnerable young adolescents and utilize the specific places young adolescents, themselves, voice as being critical settings for obtaining information on SRH issues.

International summit on the nutrition of adolescent girls and young women: consensus statement

An international summit focusing on the difficult challenge of providing adequate nutrition for adolescent girls and young women in low- and middle-income countries was held in Portland, Oregon in 2015. Sixty-seven delegates from 17 countries agreed on a series of recommendations that would make progress toward improving the nutritional status of girls and young women in countries where their access to nutrition is compromised. Delegate recommendations include: (1) elevate the urgency of nutrition for girls and young women to a high international priority, (2) raise the social status of girls and young women in all regions of the world, (3) identify major knowledge gaps in the biology of adolescence that could be filled by robust research efforts, (4) and improve access to nutrient-rich foods for girls and young women. Attention to these recommendations would improve the health of young women in all nations of the world.

Comprehensive Assessment of Health Needs of Young Minority Males Attending a Family Planning Clinic

The objective of this study was to assess the overall health, including sexual and reproductive health (SRH) knowledge and needs, sexual behaviors, and testicular health practices among young minority males. Anonymous questionnaires were administered to 18- to 25-year-old males receiving services at health clinics in a large southwestern U.S. city. The survey was completed by 258 males with a mean age of 20.8 years. Most young males (67.1%) identified as African American, and 32.9% as Hispanic. Results suggest study participants lack SRH knowledge related to pregnancy and condom effectiveness, and engage in risky sexual behavior including not using birth control at their last sexual encounter. Although 21.6% of participants had a sexually transmitted infection (STI) in the past year, approximately 80% perceived their STI/HIV risk as very low or low. Respondents had low engagement and lack of knowledge of testicular health practices. The majority of respondents (71.1%) reported having been in a physical fight one or more times and 18.1% reported being victims of intimate partner violence. These data support a need for comprehensive health services for minority young males.

Socioeconomic disparities in coverage of full immunisation among children of adolescent mothers in India, 1990-2006: a repeated cross-sectional analysis

OBJECTIVE

Studies have highlighted that children of adolescent (aged 15-19 years) mothers are likely to receive relatively poor healthcare. With an unacceptably high adolescent birth rate, India houses the highest number of adolescent mothers globally, putting children at risk of inadequate vaccination. This paper assesses trends and extent of socioeconomic disparities in the coverage of full immunisation among children of adolescent mothers in India.

DESIGN

Repeated cross-sectional analytical study.

DATA SOURCES

3 consecutive rounds of the National Family Health Survey (NFHS) conducted during 1992-1993, 1998-1999 and 2005-2006 were used. Besides, the required information is also extracted from the 2011 Indian Census.

PARTICIPANTS

Children (aged 12-23 months) of adolescent (aged 15-19 years) mothers. Sample inclusion criteria involved the last child of the adolescent eligible to avail full immunisation.

SETTING

Nationally representative sample.

DATA ANALYSIS

The Cochran-Armitage test, χ(2) test and binary logistic regression methods were applied to attain the study objective.

RESULTS

Between 1990 and 2006, a non-significant increase of 4 percentage points in full immunisation of children of adolescent mothers was estimated. During the same period, a large difference between the probability of children of adolescent mothers receiving full immunisation belonging to the least (predicted probability (PP): 0.196 in 1990-1993, and PP: 0.213 in 2003-2006) and the most (PP: 0.589 in 1990-1993, and PP: 0.645 in 2003-2006) socioeconomically privileged group was estimated, and this disparity persisted over the survey period.

CONCLUSIONS

During 1990-2006, an insufficient improvement in provision of full immunisation to children born to adolescent mothers was recorded. The study underscored the suboptimum immunisation of rural, illiterate and poor children of adolescent women. The programme and policymakers could focus on district-wise concentration of adolescent women, especially those belonging to the underprivileged groups, to design a targeted intervention to elevate the level of immunisation of children of adolescent mothers.

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.

Global Maternal, Newborn, and Child Health: Successes, Challenges, and Opportunities

Considerable progress has been made towards reducing under-5 childhood mortality in the Millennium Development Goals era. Reduction in newborn mortality has lagged behind maternal and child mortality. Effective implementation of innovative, evidence-based, and cost-effective interventions can reduce maternal and newborn mortality. Interventions aimed at the most vulnerable group results in maximal impact on mortality. Intervention coverage and scale-up remains low, inequitable and uneven in low-income countries due to numerous health-systems bottle-necks. Innovative service delivery strategies, increased integration and linkages across the maternal, newborn, child health continuum of care are vital to accelerate progress towards ending preventable maternal and newborn deaths.
