Publication Learning-by-teaching approach improves dengue knowledge in children and parents(American Society of Tropical Medicine and Hygiene, 2021) Hermida, María Julia; Pérez Santángelo, Agustín; Calero, Cecilia Inés; Goizueta, Carolina; Espinosa, Manuel; Sigman, MarianoThere is narrow evidence on which strategies are most effective for disseminating information on dengue prevention. This is particularly relevant because social habits have a great prevention capacity for dengue. We investigated how effective are children as health educators, and how much they learn as they teach. We recruited 142 children and 97 parents in Argentina's tropical area for two cluster randomized parallel trials. In Study 1, we compared the dynamics of dengue knowledge of 10-year-old children who-after receiving a dengue talk-1) listened to an unrelated topic; 2) read a booklet with information about dengue, 3) taught their parents about dengue, or 4) taught their parents about dengue, using the booklet. In Study 2, we assessed whether the parents' dengue knowledge changed after interacting with their children, in comparison with parents learning about dengue from an expert or about an unrelated topic. Children that taught their parents what they learned, using a booklet, showed 2.53 more correct responses (95% CI [0.20, 4.85]; P 5 0.027) than children who listened to an unrelated topic. This style of teaching also serves to effectively propagate knowledge: parents learned from their children the same as from an expert; and significantly more than parents who learned about an unrelated topic. Parents learned from their children even if they were taught with booklets (1.49, 95% CI [0.01, 2.96]; P 5 0.048) or without (1.94, 95% CI [0.44, 3.44]; P 5 0.006). Specifically, after being taught by their children, parents showed on average 1.49 (if they were taught with a booklet) and 1.94 (without booklet) more correct responses than parents that learned about an unrelated topic. The simple action of prompting children to teach consolidated their own knowledge and broadcasted it effectively to their parents. This strategy is a potential low to no-cost method for sharing information about dengue preventionPublication Temperament Predicts Processing Speed in Low Socioeconomic Status Rural Preschoolers(Wiley, 2020) Hermida, María Julia; Segretin, María Soledad; Shalóm, Diego Edgar; López y Rosenfeld, Matías; Abril, Marcelo Claudio; Lipina, Sebastián Javier; Sigman, MarianoExtreme poverty all over the world is concentrated in rural settings. However, studies about cognition in low socioeconomic status (SES) children are for the most part conducted in urban populations. This paper investigates, in a poor rural sample, what are the individual and socioenvironmental variables that make the difference in performance in a processing speed task. Forty four 5-year-old children were evaluated with a processing speed task; individual and socioenvironmental information was obtained from parents’ interviews. Higher scores in the effortful control dimension of temperament were associated with higher performance in the processing speed task. No other individual or socioenvironmental variable predicted the performance. These results showed that effortful control is important in processing speed and suggest that in low SES rural contexts, low effortful control children would require stronger interventionsPublication Risks for child cognitive development in rural contexts(Frontiers Media, 2019) Hermida, María Julia; Shalóm, Diego Edgar; Segretin, María Soledad; Goldin, Andrea Paula; Abril, Marcelo Claudio; Lipina, Sebastián Javier; Sigman, MarianoWhile poverty all over the world is more typical and extreme in rural contexts, interventions to improve cognition in low socioeconomic status (SES) children are for the most part based on studies conducted in urban populations. This paper investigate how poverty and rural or urban settings affect child cognitive performance. Executive functions and non-verbal intelligence performance, as well as individual and environmental information was obtained from 131 5-year-old children. For the same level of SES, children in rural settings performed consistently worse than children in urban settings. These differences could be accounted mostly by the months of past preschool attendance and the father's completed level of education. These results should inform policies and programs for children living in rural poverty worldwide, and specially in Latin AmericaPublication Corrigendum: Risks for Child Cognitive Development in Rural Contexts(2021) Shalóm, Diego Edgar; Segretin, María Soledad; Sigman, Mariano; Abril, Marcelo Claudio; Lipina, Sebastián Javier; Hermida, María JuliaWhile poverty all over the world is more typical and extreme in rural contexts, interventions to improve cognition in low socioeconomic status (SES) children are for the most part based on studies conducted in urban populations.
