Centre-based care is a significant predictor of lower body mass index in early childhood: Longitudinal evidence from Chile.
BACKGROUND: The prevalence of childhood overweight has increased by approximately 50% in the past three decades, becoming a major public health concern worldwide. In Chile, an upper middle-income country, about 38% of children between two and four years of age are overweight, almost double the average in Latin America and the Caribbean. Various environmental and individual factors, and their interactions, affect childhood weight. Emerging evidence suggests childcare may also matter. Because the public provision of centre-based care is growing, childcare may be a useful policy tool to help prevent childhood overweight. METHODS: Using a nationally representative longitudinal survey of ~ 15 000 children in Chile (2010 and 2012), we estimated whether the type of child care (centre-based or maternal) a child attended at age 24 to 36 months was a significant predictor of the child's sex-and-age-specific body-mass-index (BMI) at age 36-48 months. We restricted our sample to children in full-time maternal care at baseline (12-24 months of age; n = 1273), but tested the robustness of results with the full sample. We compared children in centre-based care and in maternal care using difference-in-difference estimators and propensity score matching, and adjusted our estimates using child, family, and neighborhood characteristics. RESULTS: Children attending centre-based care had 0.27 SD lower BMI than children in maternal care at follow-up (P < 0.05). We found suggestive evidence this association may be modulated by the child's socioeconomic status and by how frequently the child watched television: we found smaller BMI changes for children at the bottom 80% of socioeconomic status (P < 0.05) and also for children who frequently watched television (P < 0.10). Our results were robust to various model specifications. CONCLUSIONS: Our findings suggest centre-based care programs, with adequate regulation and enforcement, may be a useful support to help curb the early childhood overweight epidemic, in addition to known effects in labor supply and child development
Math Skills and Market and Non-market Outcomes: Evidence From an Amazonian Society
Research in industrial nations suggests that formal math skills are associated with improvements in market and non-market outcomes. But do these associations also hold in a highly autarkic setting with a limited formal labor market? We examined this question using observational annual panel data (2008 and 2009) from 1,121 adults in a native Amazonian society of forager-farmers in Bolivia (Tsimane’). Formal math skills were associated with an increase in wealth in durable market goods and in total wealth between data collection rounds, and with improved indicators of own reported mental health and child health. These associations did not vary significantly by people’s Spanish skills or proximity to town. We conclude that the positive association between math skills and market and non-market outcomes extends beyond industrial nations to even highly autarkic settings
Gender targeting of unconditional income transfers and child nutritional status: Experimental evidence from the Bolivian Amazon
Observational studies suggest that women’s income benefits children’s health and nutritional status, as well as education, more than men’s income, apparently because women are more likely to shift marginal resources to their children. These studies have influenced policies such as conditional cash transfers, which typically target women. However, previous studies have been unable to control for unobserved heterogeneity in child endowments and parental preferences. We report the results of a trial that allocated randomly one-time in-kind income in the form of edible rice (the main staple and cash crop in the study area) or rice seeds to the female or male household head (edible rice transfers, range: 30-395 kg/household; rice seeds: 5.9 kg/household). The trial took place in a society of native Amazonian forager-farmers in Bolivia (2008-2009). Outcomes included four anthropometric indicators of short-run nutritional status of 848 children from 40 villages. We found that the transfers produced no discernible impact on short-run (~5 months) nutritional status of children, or any differential effects between girls and boys by the gender of the household head who received the transfers. These null results probably relate to specific social norms of the Tsimane’, such as pooling of food resources, shared preferences, and relatively equal bargaining power between Tsimane’ women and men. The results highlight the probable importance of culture in household resource allocation and suggest that gender targeting in cash transfer programs might not increase investments in children in societies where women and men have more egalitarian household relationship
Evaluación preliminar técnica, económica e institucional para la implementación de un servicio de ferris en el Caribe Oriental
La Comisión Económica para América Latina y el Caribe (CEPAL), en el marco de una asistencia técnica a la Asociación de Estados del Caribe (AEC), realizó, entre otras actividades, un primer estudio sobre la posibilidad de lanzar una red regional de ferris, cuyos resultados se exponen en este documento. En la primera parte se presenta una evaluación técnica y económica del mercado del Caribe Oriental, incluidos cuatro paÃses del continente (Colombia, Guyana, Suriname y Venezuela (República Bolivariana de)), en la que se identifican los flujos potenciales y las posibles rutas para la implementación de un plan piloto, y se propone la flota que se emplazarÃa y las necesidades de infraestructura. En la segunda parte se analiza la posible inclusión de la participación privada, en su versión de asociaciones público-privadas, para el financiamiento y la operación de dichas rutas en el Caribe, asà como para el financiamiento y la operación de los puertos requeridos para ello. También se analizan casos similares exitosos de asociaciones público-privadas, de los cuales se pueden extraer elementos clave al momento de impulsar el proyecto de ferris para el Caribe.Introducción .-- I.

Prevalence of Depressive Disorder in the Adult population of Latin America: a systematic review and meta-analysis
Background: Depressive disorder is one of the leading causes of disability worldwide; however its prevalence and association with inequality and crime is poorly characterised in Latin America. This study aimed to: i. systematically review population-based studies of prevalence of ICD/DSM depressive disorder in Latin America, ii. report pooled regional, country, and sex-specific prevalence estimates, and iii. test its association with four country-level development indicators: human development (HDI), income (Gini) and gender inequality (GII), and intentional homicide rate (IHR).
Methods: We conducted a systematic review and meta-analysis of population-based studies reporting primary data on the prevalence of ICD/DSM depressive disorder in Latin America from 1990 to 2023, irrespective of language. We searched PubMed, PsycINFO, Cochrane Library, SciELO (regional database), LILAC (regional database), and available grey literature. Study quality was assessed using JBI’s critical appraisal tools. We generated pooled estimates using random-effects meta-analysis; heterogeneity was assessed using the I2 statistic. Meta-regression analyses were used to test associations of depression prevalence with indicators of inequality and human development. The study was registered with PROSPERO (CRD42019143054).
Findings: Using data from 40 studies in Latin America, lifetime, 12-month, and current prevalence of ICD/DSM depressive disorder were calculated at 12.58% (95% CI 11.00%–14.16%); 5.30% (4.55–6.06%), and 3.12% (2.22–4.03), respectively. Heterogeneity was high across lifetime, 12-month, and current prevalence, sex, and countries. 12-month and current prevalence was associated with higher Gini and GII, 12-month prevalence with lower HDI, and current prevalence with higher IHR. Interpretation We found a high prevalence of ICD/DSM depressive disorders in Latin America, and a statistically significant association with inequality and development indicators. The high heterogeneity found across prevalence periods and the major gaps in country representation underscore the need to escalate efforts to improve mental health access and research capabilities in Latin America. Systematic, comparable prevalence estimates would inform more effective decision-making in the region
Conditional cash transfers for primary education : which children are left out?
Unidad de excelencia MarÃa de Maeztu MdM-2015-0552Conditional cash transfer (CCT) programs to increase primary-school enrollment and attendance among low-income households have been shown to benefit children and households, but to date little is known about who joins such programs. We test three hypotheses about predictors of CCT program participation in indigenous societies in Bolivia, focusing on attributes of the household (ethnicity), parents (modern human capital), and children (age, sex). We model whether children receive a transfer from Bolivia's CCT program (Bono Juancito Pinto), using data from 811 school-age children and nine ethnic groups. Children from the group least exposed to Westerners (Tsimane') are 18-22 percentage points less likely to participate in the program than children from other lowland ethnic groups. Parental modern human capital and child sex do not predict participation. We discuss possible mechanisms underlying the findings and conclude that the Tsimane's current lower returns to schooling are the most likely explanation
Tool for eliminating dog-mediated human rabies through mass dog vaccination campaigns
The World Health Organization and collaborating agencies have set the goal of eliminating dog-mediated human rabies by 2030. Building on experience with rabies endemic countries, we constructed a user-friendly tool to help public health officials plan the resources needed to achieve this goal through mass vaccination of dogs
Human's Cognitive Ability to Assess Facial Cues from Photographs: A Study of Sexual Selection in the Bolivian Amazon
Background: Evolutionary theory suggests that natural selection favors the evolution of cognitive abilities which allow humans to use facial cues to assess traits of others. The use of facial and somatic cues by humans has been studied mainly in western industrialized countries, leaving unanswered whether results are valid across cultures. Methodology/Principal Findings: Our objectives were to test (i) if previous finding about raters' ability to get accurate information about an individual by looking at his facial photograph held in low-income non western rural societies and (ii) whether women and men differ in this ability. To answer the questions we did a study during July-August 2007 among the Tsimane', a native Amazonian society of foragers-farmers in Bolivia. We asked 40 females and 40 males 16-25 years of age to rate four traits in 93 facial photographs of other Tsimane' males. The four traits were based on sexual selection theory, and included health, dominance, knowledge, and sociability. The rating scale for each trait ranged from one (least) to four (most). The average rating for each trait was calculated for each individual in the photograph and regressed against objective measures of the trait from the person in the photograph. We found that (i) female Tsimane' raters were able to assess facial cues related to health, dominance, and knowledge and (ii) male Tsimane' raters were able to assess facial cues related to dominance, knowledge, and sociability. Conclusions/Significance: Our results support the existence of a human ability to identify objective traits from facial cues, as suggested by evolutionary theory
Socioeconomic factors associated with antimicrobial resistance of Pseudomonas aeruginosa, Staphylococcus aureus, and Escherichia coli in Chilean hospitals (2008-2017).
OBJECTIVE: To identify socioeconomic factors associated with antimicrobial resistance of Pseudomonas aeruginosa, Staphylococcus aureus, and Escherichia coli in Chilean hospitals (2008-2017). METHODS: We reviewed the scientific literature on socioeconomic factors associated with the emergence and dissemination of antimicrobial resistance. Using multivariate regression, we tested findings from the literature drawing from a longitudinal dataset on antimicrobial resistance from 41 major private and public hospitals and a nationally representative household survey in Chile (2008-2017). We estimated resistance rates for three priority antibiotic-bacterium pairs, as defined by the Organisation for Economic Co-operation and Development; i.e., imipenem and meropenem resistant P. aeruginosa, cloxacillin resistant S. aureus, and cefotaxime and ciprofloxacin resistant E. coli. RESULTS: Evidence from the literature review suggests poverty and material deprivation are important risk factors for the emergence and transmission of antimicrobial resistance. Most studies found that worse socioeconomic indicators were associated with higher rates of antimicrobial resistance. Our analysis showed an overall antimicrobial resistance rate of 32.5%, with the highest rates for S. aureus (40.6%) and the lowest for E. coli (25.7%). We found a small but consistent negative association between socioeconomic factors (income, education, and occupation) and overall antimicrobial resistance in univariate (p < 0.01) and multivariate analyses (p < 0.01), driven by resistant P. aeruginosa and S. aureus. CONCLUSION: Socioeconomic factors beyond health care and hospital settings may affect the emergence and dissemination of antimicrobial resistance. Preventing and controlling antimicrobial resistance requires efforts above and beyond reducing antibiotic consumption
