AbstractObjective:This article reviews information on the rapid changes in diet, activity and body composition that lower- and middle-income countries are undergoing and then examines some of the potential health implications of this transition.Design and Setting:Data came from numerous countries and also from national food balance (FAOSTAT) and World Bank sources. Nationally representative and nationwide surveys are used. The nationally representative Russian Longitudinal Monitoring Surveys from 1992–96 and the nationwide China Health and Nutrition Survey from 1989–93 are examined in detail.Results:Rapid changes in the structure of diet, in particular associated with urbanization, are documented. In addition, large changes in occupation types are documented. These are linked with rapid increases in adult obesity in Latin America and Asia. Some of the potential implications for adult health are noted.Conclusions:The rapid changes in diet, activity and obesity that are facing billions of residents of lower- and middle-income countries are cause for great concern. Linked with these changes will be a rapid increase in chronic diseases. Little to date has been done at the national level to address these problems.

BackgroundThere is currently limited literature on the association between visual impairment and suicidal thoughts and behaviours, especially among older adults from low/middle-income countries (LMICs). Thus, we aimed to investigate the associations of objectively measured distance visual impairment with suicidal ideation and suicide attempts among adults aged ≥50 years from six LMICs and to identify potential mediators.MethodsCross-sectional, community-based, nationally representative data from the WHO Study on global AGEing and adult health were analysed. Objective distance visual acuity was measured using the tumbling E logMAR chart, and vision impairment was categorised as none, mild, moderate and severe. Self-reported information on past 12-month suicidal ideation and suicide attempts was also collected. Multivariable logistic regression and mediation analysis were conducted.ResultsData on 34 129 individuals aged ≥50 years (mean (SD) age, 62.4 (16.0) years; 47.9% men) were analysed. After adjustment for potential confounders, compared with no visual impairment, severe visual impairment was significantly associated with suicidal ideation (OR=9.50; 95% CI=2.47 to 36.52). Moderate and severe visual impairment were significantly associated with a 2.22 (95% CI=1.14 to 4.35) and 11.50 (95% CI=1.44 to 91.88) times higher odds of suicide attempts, respectively. Disability, poor self-rated health, mobility and loneliness explained 14.0%, 9.3%, 7.2% and 6.3% of the association between moderate/severe visual impairment and suicide attempts, respectively.ConclusionInterventions to reduce suicidal ideation and suicide attempts among older adults with visual impairment in LMICs are required, targeting identified mediators, while using tested strategies for suicide prevention per se in LMICs may yield beneficial outcomes.

Abstract Objective: To assess whether the observed prevalence of the double burden of malnutrition (DBM) would be higher than expected on the basis of chance, through analyses at national, wealth quintile and individual child levels. Design: We selected nationally representative surveys from low- and middle-income countries (LMIC) carried out since 2005 with anthropometric measures on children under 5 years of age. Household wealth was assessed through asset indices. The expected prevalence of DBM was estimated by multiplying the prevalence of stunting (low height/length for age) and overweight (high weight for height/length). The WHO recommended cut-offs (20% for stunting and 10% for overweight) that were used to define DBM at national level. DBM at individual level was defined as co-occurrence of stunting and overweight in the same child. Setting: Nationally representative surveys from ninety-three LMIC. Participants: A total of 825 633 children were studied. Results: DBM at national level was observed in five countries, whereas it would be expected to occur in eleven countries. Six countries did not present evidence of DBM at national level but did so in at least one wealth quintile. At individual level, thirty countries (32·3%) showed higher prevalence of DBM than would be expected, but most differences were small except for Syria, Azerbaijan, Albania and Egypt. Conclusions: The observed number of countries or socio-economic subgroups within countries with the DBM using recommended thresholds was below what would be expected by chance. However, individual-level analyses showed that one-third of countries presented higher prevalence of DBM than would be expected.

Currently, there are limited data on the association between multimorbidity (i.e., ≥ 2 chronic conditions) and anxiety, especially among the older population in low- and middle-income countries (LMICs). Thus, the aim of the present study was to examine the association between multimorbidity and anxiety symptoms in a large sample of adults aged ≥ 50 years from six LMICs (China, India, Ghana, Mexico, Russia, South Africa). Cross-sectional, nationally representative, community-based data from the Study on Global Ageing and Adult Health (SAGE) were analysed. A total of 11 chronic physical conditions were assessed. Anxiety symptoms referred to extreme/severe problems with worry or anxiety in the past 30 days. Multivariable logistic regression and meta-analyses were conducted. Data on 34,129 adults aged ≥ 50 years were analysed (mean (SD) age 62.4 (16.0) years; 52.1% females). Compared with no chronic conditions, 2, 3, 4, and ≥ 5 chronic conditions were significantly associated with 1.47 (95% CI = 1.08–1.98), 2.46 (95% CI = 1.74–3.47), 3.04 (95% CI = 2.15–4.30), and 4.70 (95% CI = 2.99–7.38) times higher odds of anxiety symptoms, respectively. A country-wise analysis showed that multimorbidity was significantly associated with anxiety symptoms in all six countries (OR = 1.78–12.39) with the overall estimate based on a meta-analysis being OR = 2.29 (95% CI = 1.71–3.07). Multimorbidity was associated with higher odds of anxiety symptoms among older adults in LMICs. Future longitudinal studies are warranted to assess the temporal associations and mechanisms underlying this association.

The Impact

Preterm birth and stillbirth are important global perinatal health indicators. Definitions of these indicators can differ between countries, affecting comparability of preterm birth and stillbirth rates across countries. This study aimed to document national-level adherence to World Health Organization (WHO) definitions of preterm birth and stillbirth in the WHO Western Pacific region. A systematic search of government health websites and 4 electronic databases was conducted. Any official report or published study describing the national definition of preterm birth or stillbirth published between 2000 and 2020 was eligible for inclusion. A total of 58 data sources from 21 countries were identified. There was considerable variation in how preterm birth and stillbirth was defined across the region. The most frequently used lower gestational age threshold for viability of preterm birth was 28 weeks gestation (range 20-28 weeks), and stillbirth was most frequently classified from 20 weeks gestation (range 12-28 weeks). High-income countries more frequently used earlier gestational ages for preterm birth and stillbirth compared with low- to middle-income countries. The findings highlight the importance of clear, standardized, internationally comparable definitions for perinatal indicators. Further research is needed to determine the impact on regional preterm birth and stillbirth rates.

IntroductionGestational weight gain (GWG) has important implications for maternal and child health and is an ideal modifiable factor for preconceptional and antenatal care. However, the average levels of GWG across all low-income and middle-income countries of the world have not been characterised using nationally representative data.MethodsGWG estimates across time were computed using data from the Demographic and Health Surveys Program. A hierarchical model was developed to estimate the mean total GWG in the year 2015 for all countries to facilitate cross-country comparison. Year and country-level covariates were used as predictors, and variable selection was guided by the model fit. The final model included year (restricted cubic splines), geographical super-region (as defined by the Global Burden of Disease Study), mean adult female body mass index, gross domestic product per capita and total fertility rate. Uncertainty ranges (URs) were generated using non-parametric bootstrapping and a multiple imputation approach. Estimates were also computed for each super-region and region.ResultsLatin America and Caribbean (11.80 kg (95% UR: 6.18, 17.41)) and Central Europe, Eastern Europe and Central Asia (11.19 kg (95% UR: 6.16, 16.21)) were the super-regions with the highest GWG estimates in 2015. Sub-Saharan Africa (6.64 kg (95% UR: 3.39, 9.88)) and North Africa and Middle East (6.80 kg (95% UR: 3.17, 10.43)) were the super-regions with the lowest estimates in 2015. With the exception of Latin America and Caribbean, all super-regions were below the minimum GWG recommendation for normal-weight women, with Sub-Saharan Africa and North Africa and Middle East estimated to meet less than 60% of the minimum recommendation.ConclusionThe levels of GWG are inadequate in most low-income and middle-income countries and regions. Longitudinal monitoring systems and population-based interventions are crucial to combat inadequate GWG in low-income and middle-income countries.

AbstractSeveral studies have documented the burden and risk factors associated with diarrhoea in low and middle-income countries (LMIC). To the best of our knowledge, the contextual and compositional factors associated with diarrhoea across LMIC were poorly operationalized, explored and understood in these studies. We investigated multilevel risk factors associated with diarrhoea among under-five children in LMIC. We analysed diarrhoea-related information of 796,150 under-five children (Level 1) nested within 63,378 neighbourhoods (Level 2) from 57 LMIC (Level 3) using the latest data from cross-sectional and nationally representative Demographic Health Survey conducted between 2010 and 2018. We used multivariable hierarchical Bayesian logistic regression models for data analysis. The overall prevalence of diarrhoea was 14.4% (95% confidence interval 14.2–14.7) ranging from 3.8% in Armenia to 31.4% in Yemen. The odds of diarrhoea was highest among male children, infants, having small birth weights, households in poorer wealth quintiles, children whose mothers had only primary education, and children who had no access to media. Children from neighbourhoods with high illiteracy [adjusted odds ratio (aOR) = 1.07, 95% credible interval (CrI) 1.04–1.10] rates were more likely to have diarrhoea. At the country-level, the odds of diarrhoea nearly doubled (aOR = 1.88, 95% CrI 1.23–2.83) and tripled (aOR = 2.66, 95% CrI 1.65–3.89) among children from countries with middle and lowest human development index respectively. Diarrhoea remains a major health challenge among under-five children in most LMIC. We identified diverse individual-level, community-level and national-level factors associated with the development of diarrhoea among under-five children in these countries and disentangled the associated contextual risk factors from the compositional risk factors. Our findings underscore the need to revitalize existing policies on child and maternal health and implement interventions to prevent diarrhoea at the individual-, community- and societal-levels. The current study showed how the drive to the attainment of SDGs 1, 2, 4, 6 and 10 will enhance the attainment of SDG 3.

Child domestic work (CDW) is a hidden form of child labour. Globally, there were an estimated 17.2 million CDWs aged 5–17 in 2012, but there has been little critical analysis of methods and survey instruments used to capture prevalence of CDW. This rapid systematic review identified and critically reviewed the measurement tools used to estimate CDWs in Low- and Middle-Income Countries, following PRISMA guidelines (PROSPERO registration: CRD42019148702). Fourteen studies were included. In nationally representative surveys, CDW prevalence ranged from 17% among 13–24-year-old females in Haiti to 2% of children aged 10–17 in Brazil. Two good quality studies and one good quality measurement tool were identified. CDW prevalence was assessed using occupation-based methods (n = 9/14), household roster (n = 7) and industry methods (n = 4). Six studies combined approaches. Four studies included task-based questions; one study used this method to formally calculate prevalence. The task-based study estimated 30,000 more CDWs compared to other methods. CDWs are probably being undercounted, based on current standard measurement approaches. We recommend use of more sensitive, task-based methods for inclusion in household surveys. The cognitive and pilot testing of newly developed task-based questions is essential to ensure comprehension. In analyses, researchers should consider CDWs who may be disguised as distant or non-relatives.

Abstract Violence against women and girls (VAWG) is a global problem with profound consequences. Although there is a growing body of evidence on the effectiveness of VAWG prevention interventions, economic data are scarce. We carried out a cross-country study to examine the costs of VAWG prevention interventions in low- and middle-income countries. We collected primary cost data on six different pilot VAWG prevention interventions in six countries: Ghana, Kenya, Pakistan, Rwanda, South Africa and Zambia. The interventions varied in their delivery platforms, target populations, settings and theories of change. We adopted a micro-costing methodology. We calculated total costs and a number of unit costs common across interventions (e.g. cost per beneficiary reached). We used the pilot-level cost data to model the expected total costs and unit costs of five interventions scaled up to the national level. Total costs of the pilots varied between ∼US $208 000 in a small group intervention in South Africa to US $2 788 000 in a couples and community-based intervention in Rwanda. Staff costs were the largest cost input across all interventions; consequently, total costs were sensitive to staff time use and salaries. The cost per beneficiary reached in the pilots ranged from ∼US $4 in a community-based intervention in Ghana to US $1324 for one-to-one counselling in Zambia. When scaled up to the national level, total costs ranged from US $32 million in Ghana to US $168 million in Pakistan. Cost per beneficiary reached at scale decreased for all interventions compared to the pilots, except for school-based interventions due to differences in student density per school between the pilot and the national average. The costs of delivering VAWG prevention vary greatly due to differences in the geographical reach, number of intervention components and the complexity of adapting the intervention to the country. Cost-effectiveness analyses are necessary to determine the value for money of interventions.

The Impact

Abstract Background Global recognition of antimicrobial resistance (AMR) as an urgent public health problem has galvanized national and international efforts. Chief among these are interventions to curb the overuse and misuse of antibiotics. However, the impact of these initiatives is not fully understood, making it difficult to assess the expected effectiveness and sustainability of further policy interventions. We conducted a systematic review to summarize existing evidence for the impact of nationally enforced interventions to reduce inappropriate antibiotic use in humans. Methods We searched seven databases and examined reference lists of retrieved articles. To be included, articles had to evaluate the impact of national responsible use initiatives. We excluded studies that only described policy implementations. Results We identified 34 articles detailing interventions in 21 high- and upper-middle-income countries. Interventions addressing inappropriate antibiotic access included antibiotic committees, clinical guidelines and prescribing restrictions. There was consistent evidence that these were effective at reducing antibiotic consumption and prescription. Interventions targeting inappropriate antibiotic demand consisted of education campaigns for healthcare professionals and the general public. Evidence for this was mixed, with several studies showing no impact on overall antibiotic consumption. Conclusions National-level interventions to reduce inappropriate access to antibiotics can be effective. However, evidence is limited to high- and upper-middle-income countries, and more evidence is needed on the long-term sustained impact of interventions. There should also be a simultaneous push towards standardized outcome measures to enable comparisons of interventions in different settings.
