Recent trends in maternal and child health inequalities in Latin America and the Caribbean: analysis of repeated national surveys.

BACKGROUND: Although most Latin American and the Caribbean (LAC) countries made important progress in maternal and child health indicators from the 1990s up to 2010, little is known about such progress in the last decade. This study aims at documenting progress for each country as a whole, and to assess how within-country socioeconomic inequalities are evolving over time. METHODS: We identified LAC countries for which a national survey was available between 2011-2015 and a second comparable survey in 2018-2020. These included Argentina, Costa Rica, Cuba, the Dominican Republic, Guyana, Honduras, Peru, and Suriname. The 16 surveys included in the analysis collected nationally representative data on 221,989 women and 152,983 children using multistage sampling. Twelve health-related outcomes were studied, seven of which related to intervention coverage: the composite coverage index, demand for family planning satisfied with modern methods, antenatal care (four or more visits and eight or more visits), skilled attendant at birth, postnatal care for the mother and full immunization coverage. Five additional impact indicators were also investigated: stunting prevalence among under-five children, tobacco use by women, adolescent fertility rate, and under-five and neonatal mortality rates. For each of these indicators, average annual relative change rates were calculated between the baseline and endline national level estimates, and changes in socioeconomic inequalities over time were assessed using the slope index of inequality. RESULTS: Progress over time and the magnitude of inequalities varied according to country and indicator. For countries and indicators where baseline levels were high, as Argentina, Costa Rica and Cuba, progress was slow and inequalities small for most indicators. Countries that still have room for improvements, such as Guyana, Honduras, Peru and Suriname, showed faster progress for some but not all indicators, although also had wider inequalities. Among the countries studied, Peru was the top performer in terms of increasing coverage and reducing inequalities over time, followed by Honduras. Declines in family planning and immunization coverage were observed in some countries, and the widest inequalities were present for adolescent fertility and antenatal care coverage with eight or more visits. CONCLUSIONS: Although LAC countries are well placed in terms of current levels of health indicators compared to most low- and middle-income countries, important inequalities remain, and reversals are being observed in some areas. More targeted efforts and actions are needed in order to leave no one behind. Monitoring progress with an equity lens is essential, but this will require further investment in conducting surveys routinely.

Trends and inequities in adolescent childbearing in Latin American and Caribbean countries across generations and over time: a population-based study.

BACKGROUND: Latin America and the Caribbean present the second highest adolescent fertility rate in the world, only after sub-Saharan Africa, and have reached the third position globally in the incidence of motherhood in adolescence. We aimed to explore trends and inequities in adolescent childbearing in the region. METHODS: We used nationally representative household surveys from Latin American and Caribbean countries to address trends in early childbearing (proportion of women having their first livebirth before age 18 years) over generations and in adolescent fertility rates (AFRs; livebirths per 1000 women aged 15-19 years) over time. For early childbearing, we analysed the most recent survey conducted since 2010 from 21 countries (2010-20); for AFR, we analysed nine countries with two or more surveys, with the most recent being conducted from 2010 onwards. For both indicators, variance-weighted least-square regression was used to estimate the average absolute changes (AACs) at the national level and by wealth (bottom 40% vs top 60%), urban versus rural residence, and ethnicity. FINDINGS: Among 21 countries studied, we noted a decrease in early childbearing along generations in 13 of them, with declines varying from -0·6 percentage points (95% CI -1·1 to -0·1) in Haiti to -2·7 percentage points (-4·0 to -1·4) in Saint Lucia. We observed increases over generations in Colombia (1·2 percentage points [0·8 to 1·5]) and Mexico (1·3 percentage points [0·5 to 2·0]) and no changes in Bolivia and Honduras. The fastest early childbearing decline occurred among rural women, whereas no clear pattern was observed for wealth groups. Decreasing estimates from oldest to youngest generations were found among Afro-descendants and non-Afro-descendant and non-indigenous groups, but results were mixed for indigenous people. All nine countries with data for AFR presented reductions over time (-0·7 to -6·5 births per 1000 women per year), with the steepest declines observed in Ecuador, Guyana, Guatemala, and the Dominican Republic. In general, adolescents in rural areas and the poorest adolescents had the largest reductions in AFR. If current trends persist, by 2030 most countries will present AFR values ranging between 45 and 89 births per 1000 women, with notable wealth-related inequalities. INTERPRETATION: Our results indicate a reduction in AFR in Latin American and Caribbean countries that was not necessarily accompanied by a decrease in early childbearing overall. Large inequalities both between countries and within countries were observed, with no clear reduction over time. Understanding trends in adolescent childbearing and its determinants is essential for planning and designing programmes to ensure the desired reductions in rates and gaps across population subgroups.

Measurement of Mental Health Among Adolescents at the Population Level: A Multicountry Protocol for Adaptation and Validation of Mental Health Measures.

PURPOSE: Mental disorders are among the leading causes of disability among adolescents aged 10-19 years. However, data on prevalence of mental health conditions are extremely sparse across low- and middle-income countries, even though most adolescents live in these settings. This data gap is further exacerbated because few brief instruments for adolescent mental health are validated in these settings, making population-level measurement of adolescent mental health especially cumbersome to carry out. In response, the UNICEF has undertaken the Measurement of Mental Health Among Adolescents at the Population Level (MMAP) initiative, validating open-access brief measures and encouraging data collection in this area. METHODS: This protocol presents the MMAP mixed-methods approach for cultural adaptation and clinical validation of adolescent mental health data collection tools across settings. Qualitative activities include an initial translation and adaptation, review by mental health experts, focus-group discussions with adolescents, cognitive interviews, synthesis of findings, and back-translation. An enriched sample of adolescents with mental health problems is then interviewed with the adapted tool, followed by gold-standard semistructured diagnostic interviews. RESULTS: The study protocol is being implemented in Belize, Kenya, Nepal, and South Africa and includes measures for anxiety, depression, functional limitations, suicidality, care-seeking, and connectedness. Analyses, including psychometrics, will be conducted individually by country and combined across settings to assess the MMAP methodological process. DISCUSSION: This protocol contributes to closing the data gap on adolescent mental health conditions by providing a rigorous process of cross-cultural adaptation and validation of data collection approaches.

Validation of the Kriol and Belizean English Adaptation of the Revised Children's Anxiety and Depression Scale for Use With Adolescents in Belize.

PURPOSE: To validate a culturally-adapted Kriol and Belizean English version of the Revised Children's Anxiety and Depression Scale (RCADS) through comparison with clinical diagnoses made using the Kiddie Schedule of Affective Disorders and Schizophrenia. METHODS: Participants comprised of 256 adolescents aged 10-14 years and 15-19 years, who completed the adapted RCADS (10 depression items, 12 anxiety items) in one-on-one interviews, followed by a diagnostic assessment using Kiddie Schedule of Affective Disorders and Schizophrenia administered by trained clinicians. Sensitivity, specificity, positive predictive value, negative predictive value, diagnostic odds ratios, area under the curve (AUC), and Youden's Index were calculated for RCADS cutoffs and scores on the total scale and anxiety and depression subscales. RESULTS: For adolescents aged 10-14 years (n = 161), the AUC was 0.72 for the full scale, 0.67 for anxiety subscale, and 0.76 for depression subscale. For adolescents aged 15-19 years (n = 95), the AUCs were 0.82, 0.77, and 0.83. Most depression items performed well in discriminating those with and without diagnoses. Separation anxiety items performed poorly. "Thoughts of death" were common even among adolescents not meeting diagnostic criteria. The RCADS depression subscale presented the strongest psychometric properties with adolescents aged 15-19 years (at cutoff of 13, sensitivity = 0.83, specificity = 0.77, positive predictive value = 0.47, negative predictive value = 0.95, odds ratio = 15.96). CONCLUSION: The adapted RCADS-22 had acceptable categorization for adolescents aged 10-14 years and excellent categorization for adolescents aged 15-19 years; therefore, the tool is recommended for use among the latter age group. Based on sensitivity and specificity values at different cutoffs, guidance is provided to select different thresholds to suit clinical, public health, or other uses to detect and quantify adolescent depression and anxiety in Belize.

Implications for Mental Health Promotion and Prevention Interventions: Findings From Adolescent Focus Group Discussions in Belize, Kazakhstan, and South Africa.

PURPOSE: This study aimed to understand 10- to 19-year-old adolescents' conceptions of mental health and well-being, and suggestions for appropriate interventions, in three low- and middle-income countries to inform the design of adolescent-responsive preventive and promotive mental health programming. METHODS: Ninety-one adolescents participated in focus group discussions in Belize, Kazakhstan, and South Africa. The discussions were recorded, transcribed, translated, and analyzed using thematic analysis. RESULTS: Adolescents were active contributors to the discussions and provided important information and solutions for improving adolescents' mental health from interpersonal skills training to interventions in schools and communities. Adolescents identified a need for social emotional skills development, particularly regarding interpersonal relationships and navigating peer pressure and bullying. Furthermore, the discussions highlighted the need for programming to be tailored to the local context regarding language, contextual challenges faced by adolescents, and choice of program facilitators. Adolescents valued supportive interactions with adults in their lives and recommended that programs should include teacher/parent training on interacting with adolescents. CONCLUSIONS: These findings highlight that adolescents are valuable partners in developing adolescent health interventions and show that social emotional skills are key components in such interventions. These programs should be culturally and locally appropriate and include components for teachers and parents.

Detecting Depression and Anxiety Among Adolescents in South Africa: Validity of the isiXhosa Patient Health Questionnaire-9 and Generalized Anxiety Disorder-7.

PURPOSE: Screening tools such as the Patient Health Questionnaire-9 (PHQ-9) and the Generalized Anxiety Disorder-7 (GAD-7) could potentially be used in resource-limited settings to identify adolescents who need mental health support. We examined the criterion validity of the isiXhosa versions of the PHQ-9 and GAD-7 in detecting depression and anxiety among adolescents (10-19 years) in South Africa. METHODS: Adolescents were recruited from the general population and from nongovernmental organizations working with adolescents in need of mental health support. The PHQ-9 and GAD-7 were culturally adapted and translated into isiXhosa and administered to 302 adolescents (56.9% female). The Kiddie Schedule for Affective Disorders and Schizophrenia was administered by trained clinicians as the gold standard diagnostic measure for depression and anxiety. RESULTS: For the PHQ-9, the area under the curve was 0.88 for the full sample of adolescents (10-19 years old). A score of ≥10 had 91% sensitivity and 76% specificity for detecting adolescents with depression. For the GAD-7, the area under the curve was 0.78, and cutoff scores with an optimal sensitivity-specificity balance were low (≥6). A score of ≥6 had 67% sensitivity and 75% specificity for detecting adolescents with anxiety. DISCUSSION: The culturally adapted isiXhosa version of the PHQ-9 can be used as a valid measure for depression in adolescents. Further research on the GAD-7 for use with adolescents is recommended.

Validation of the English and Swahili Adaptation of the Patient Health Questionnaire-9 for Use Among Adolescents in Kenya.

PURPOSE: Our study aimed to validate culturally adapted English and Swahili versions of the Patient Health Questionnaire-9 (PHQ-9) for use with adolescents in Kenya. Criterion validity was determined with clinician-administered diagnostic interviews using the Kiddie Schedule of Affective Disorders and Schizophrenia. METHODS: A total of 250 adolescents comprising 148 (59.2%) females and 102 (40.8%) males aged 10-19 years (mean = 14.76; standard deviation = 2.78) were recruited. The PHQ-9 was administered to all respondents concurrently in English and Swahili. Adolescents were later interviewed by clinicians using Kiddie Schedule of Affective Disorders and Schizophrenia to determine the presence or absence of current symptoms of major depressive disorder. Sensitivity specificity, positive predictive value (PPV) and negative predictive value (NPV), and likelihood ratios for various cut-off scores for PHQ-9 were analyzed using receiver operating characteristic curves. RESULTS: The internal consistency (Cronbach's α) for PHQ-9 was 0.862 for the English version and 0.834 for Swahili version. The area under the curve was 0.89 (95% confidence interval, 0.84-0.92) and 0.87 (95% confidence interval, 0.82-0.90) for English and Swahili version, respectively, on receiver operating characteristic analysis. A cut-off of ≥ 9 on the English-language version had a sensitivity of 95.0%, specificity of 73.0%, PPV of 0.23, and NPV of 0.99; a cut-off of ≥ 9 on the Swahili version yielded a sensitivity of 89.0%, specificity of 70.0%, PPV of 0.20, and NPV of 0.90. DISCUSSION: Psychometric properties were comparable across both English-adapted and Swahili-adapted version of the PHQ-9, are reliable, and valid instrument to detect major depressive disorder among adolescents which can be used in resource-limited settings for early identification of adolescents in need of mental health support.

Toward a Demand-Driven, Collaborative Data Agenda for Adolescent Mental Health.

PURPOSE: Existing datasets and research in the field of adolescent mental health do not always meet the needs of practitioners, policymakers, and program implementers, particularly in the context of vulnerable populations. Here, we introduce a collaborative, demand-driven methodology for the development of a strategic adolescent mental health research agenda. Ultimately, this agenda aims to guide future data sharing and collection efforts that meet the most pressing data needs of key stakeholders. METHODS: We conducted a rapid literature search to summarize common themes in adolescent mental health research into a "topic map". We then hosted two virtual workshops with a range of international experts to discuss the topic map and identify shared priorities for future collaboration and research. RESULTS: Our topic map identifies 10 major themes in adolescent mental health, organized into system-level, community-level, and individual-level categories. The engagement of cross-sectoral experts resulted in the validation of the mapping exercise, critical insights for refining the topic map, and a collaborative list of priorities for future research. DISCUSSION: This innovative agile methodology enables a focused deliberation with diverse stakeholders and can serve as the starting point for data generation and collaboration practices, both in the field of adolescent mental health and other topics.

Translation and Adaptation of the Revised Children's Anxiety and Depression Scale: A Qualitative Study in Belize.

BACKGROUND: Adapting data collection instruments using transcultural translation and adaptation processes is essential to ensure that respondents comprehend the items and the original meaning is retained across languages and contexts. This approach is central to UNICEF's efforts to expand the use of standard data collection tools across settings and close the global data gap on adolescent mental health. METHODS: We conducted transcultural translation and adaptation processes in Belize using the Revised Children's Anxiety and Depression Scale (RCADS). Items from the original scale were translated into Belizean English and Kriol, reviewed by local mental health experts, and discussed in focus groups. Cognitive interviews were conducted with adolescents and parents. The information collected was analyzed with cultural equivalence domains: comprehensibility, acceptability, relevance, completeness, and technical equivalence. Bilingual discussions of findings informed the final item wordings, and the adapted tool was back-translated. RESULTS: Adaptation of terms and specific expressions were done to improve comprehensibility and to ensure the appropriate clinical meaning. For example, the expression 'feeling scared' was perceived to imply immaturity or threaten masculinity and was adapted to 'feeling afraid.' Expressions like "shaky" were modified to "trimble" in Kriol. Statements were reworded as questions to enhance acceptability and comprehensibility. DISCUSSION: A culturally adapted version of the RCADS was developed for use among adolescents in Belize in Belizean English and Kriol. The transcultural translation and adaptation procedure can be applied for other settings or tools to design contextual adaptations of mental health instruments prior to their validation or use in new settings.

Objectives: Latin America and the Caribbean (LAC) countries have made important progress towards achieving the Sustainable Development Goal (SDG) targets related to health (SDG3) at the national level. However, vast within-country health inequalities remain. We present a baseline of health inequalities in the region, against which progress towards the SDGs can be monitored. Setting: We studied 21 countries in LAC using data from Demographic and Health Surveys and Multiple Indicator Cluster Survey carried out from 2011 to 2016. Participants: The surveys collect nationally representative data on women and children using multistage sampling. In total, 288 207 women and 195 092 children made part of the surveys in the 21 countries. Outcome measures: Five health intervention indicators were studied, related to reproductive and maternal health, along with adolescent fertility and neonatal and under-five mortality rates. Inequalities in these indicators were assessed through absolute and relative measures. Results: In most countries, subnational geographical health gradients were observed for nearly all women, child, and adolescent (WCA) indicators. Coverage of key interventions was higher in urban areas and among the richest, compared with rural areas and poorer quintiles. Analyses by woman's age showed that coverage was lower in adolescent girls than older women for family planning indicators. Pro-urban and pro-rich inequalities were also seen for mortality in most countries. Conclusions: Regional averages hide important health inequalities between countries, but national estimates hide still greater inequalities between subgroups of women, children and adolescents. To achieve the SDG3 targets and leave no one behind, it is essential to close health inequality gaps within as well as between countries.

SDG3-related inequalities in women's, children's and adolescents' health: an SDG monitoring baseline for Latin America and the Caribbean using national cross-sectional surveys.

OBJECTIVES: Latin America and the Caribbean (LAC) countries have made important progress towards achieving the Sustainable Development Goal (SDG) targets related to health (SDG3) at the national level. However, vast within-country health inequalities remain. We present a baseline of health inequalities in the region, against which progress towards the SDGs can be monitored. SETTING: We studied 21 countries in LAC using data from Demographic and Health Surveys and Multiple Indicator Cluster Survey carried out from 2011 to 2016 PARTICIPANTS: The surveys collect nationally representative data on women and children using multistage sampling. In total, 288 207 women and 195 092 children made part of the surveys in the 21 countries. OUTCOME MEASURES: Five health intervention indicators were studied, related to reproductive and maternal health, along with adolescent fertility and neonatal and under-five mortality rates.

Analyses by woman's age showed that coverage was lower in adolescent girls than older women for family planning indicators. Pro-urban and pro-rich inequalities were also seen for mortality in most countries. CONCLUSIONS: Regional averages hide important health inequalities between countries, but national estimates hide still greater inequalities between subgroups of women, children and adolescents. To achieve the SDG3 targets and leave no one behind, it is essential to close health inequality gaps within as well as between countries.

Framework for Evaluating the Health Impact of the Scale-Up of Malaria Control Interventions on All-Cause Child Mortality in Sub-Saharan Africa.

Concerted efforts from national and international partners have scaled up malaria control interventions, including insecticide-treated nets, indoor residual spraying, diagnostics, prompt and effective treatment of malaria cases, and intermittent preventive treatment during pregnancy in sub-Saharan Africa (SSA). This scale-up warrants an assessment of its health impact to guide future efforts and investments; however, measuring malaria-specific mortality and the overall impact of malaria control interventions remains challenging. In 2007, Roll Back Malaria's Monitoring and Evaluation Reference Group proposed a theoretical framework for evaluating the impact of full-coverage malaria control interventions on morbidity and mortality in high-burden SSA countries. Recently, several evaluations have contributed new ideas and lessons to strengthen this plausibility design. This paper harnesses that new evaluation experience to expand the framework, with additional features, such as stratification, to examine subgroups most likely to experience improvement if control programs are working; the use of a national platform framework; and analysis of complete birth histories from national household surveys. The refined framework has shown that, despite persisting data challenges, combining multiple sources of data, considering potential contributions from both fundamental and proximate contextual factors, and conducting subnational analyses allows identification of the plausible contributions of malaria control interventions on malaria morbidity and mortality.

The contribution of poor and rural populations to national trends in reproductive, maternal, newborn, and child health coverage: analyses of cross-sectional surveys from 64 countries.

BACKGROUND: Coverage levels for essential interventions aimed at reducing deaths of mothers and children are increasing steadily in most low-income and middle-income countries. We assessed how much poor and rural populations in these countries are benefiting from national-level progress. METHODS: We analysed trends in a composite coverage indicator (CCI) based on eight reproductive, maternal, newborn, and child health interventions in 209 national surveys in 64 countries, from Jan 1, 1994, to Dec 31, 2014. Trends by wealth quintile and urban or rural residence were fitted with multilevel modelling. We used an approach akin to the calculation of population attributable risk to quantify the contribution of poor and rural populations to national trends. FINDINGS: From 1994 to 2014, the CCI increased by 0·82 percent points a year across all countries; households in the two poorest quintiles had an increase of 0·99 percent points a year, which was faster than that for the three wealthiest quintiles (0·68 percent points). Gains among poor populations were faster in lower-middle-income and upper-middle-income countries than in low-income countries. Globally, national level increases in CCI were 17·5% faster than they would have been without the contribution of the two poorest quintiles. Coverage increased more rapidly annually in rural (0·93 percent points) than urban (0·52 percent points) areas. INTERPRETATION: National coverage gains were accelerated by important increases among poor and rural mothers and children. Despite progress, important inequalities persist, and need to be addressed to achieve the Sustainable Development Goals. FUNDING: UNICEF, Wellcome Trust.
