BALZA, Auteur ; Andrés CAMACHO, Auteur ; Nicolás GÓMEZ-PARRA, Auteur Article en page(s) : p.929-940 Langues : Anglais (eng) Mots-clés : Heat exposure  early childhood development  climate change  temperature Index. décimale : PER Périodiques Résumé : Background Increasing evidence suggests that climate change, along with its cascading impacts on ecosystems, societies, and communities, has significant effects on both physical and mental health. However, less is known about how exposure to excessive heat early in life may influence the development of foundational skills that shape lifelong developmental trajectories. This study examined the effects of ambient heat on early childhood development across six countries, using geographic and time-stamped data on child development and ambient temperature. Methods Our primary outcome is the Early Childhood Development Index. We used linear probability models with geographic and seasonality fixed effects to account for baseline climatic conditions, as well as other individual and contextual covariates to address potential selection bias. The sample comprised 19,607 children aged three and four from Georgia, The Gambia, Madagascar, Malawi, Sierra Leone, and the State of Palestine, all participants in Multiple Indicators Cluster Surveys collected between 2017 and 2020. We merged these data with temperature data from the ERA5-Land Monthly Aggregated Climate Dataset, calculating the mean monthly maximum temperature children experienced from birth to interview. Results We found that children exposed to average maximum temperatures above 32°C were less likely to be developmentally on track compared to those exposed to cooler temperatures, even after accounting for baseline average climatic conditions and other covariates. Domain-specific models indicate that these effects were most pronounced in literacy and numeracy skills. Subgroup analyses revealed that the negative impacts were particularly severe for children in economically disadvantaged households and urban areas, and for those lacking access to adequate water and sanitation. Conclusions This study highlights the potential impact of excessive heat on early childhood development, emphasizing the need for policies and interventions that enhance preparedness, adaptation, and resilience to support human development in an rapidly warming world.

The acute effects of community violence on young children's regulatory, behavioral, and developmental outcomes in a low-income urban sample in Brazil / Dana Charles MCCOY in Journal of Child Psychology and Psychiatry, 65-5 (May 2024)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 65-5 (May 2024) . - p.620-630 Titre : The acute effects of community violence on young children's regulatory, behavioral, and developmental outcomes in a low-income urban sample in Brazil Type de document : texte imprimé Auteurs : Dana Charles MCCOY, Auteur ; Marta DORMAL, Auteur ; Jorge CUARTAS, Auteur ; Angélica CARREIRA DOS SANTOS, Auteur ; Günther FINK, Auteur ; Alexandra BRENTANI, Auteur Article en page(s) : p.620-630 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background Existing research on the impacts of adversity on young children's psychological well-being has largely focused on household-level risk factors using observational methods in high-income countries. This study leverages natural variation in the timing and location of community homicides to estimate their acute effects on the regulatory, behavioral, and developmental outcomes of Brazilian 3-year-olds. Methods We compared the outcomes of children who were assessed soon after a recent neighborhood homicide to those of children from the same residential neighborhoods who had not recently experienced community violence. Our sample included 3,241 3-year-olds (Mage = 41.05 months; 53% female; 45% caregiver education less than middle school; 26% receiving a public assistance program) from seven neighborhoods in São Paulo, Brazil. Child outcome measures included parent reports of effortful control and behavior problems as well as direct assessments of children's developmental (cognitive, language, and motor) skills. Community homicides were measured using police records. Results Recent exposure to community homicides was associated with lower effortful control, higher behavior problems, and lower overall developmental performance for children (d = .05-.20 standard deviations; p = ns - <.001). Effects were consistent across subgroups based on sociodemographic characteristics and environmental supports, but generally largest when community violence exposure was geographically proximal (within 600 m of home) and recent (within 2 weeks prior to assessment). Conclusions Results highlight the pervasive effects that community violence can have on young children as well as the need to expand support to mitigate these effects and prevent inequities early in life.
