A exposi\u00e7\u00e3o \u00e0 viol\u00eancia e a outras formas de estresse t\u00f3xico nos primeiros anos de vida est\u00e1 relacionada a preju\u00edzos do desenvolvimento cognitivo e social, com consequ\u00eancias que podem persistir por toda a vida. Realizamos medidas da exposi\u00e7\u00e3o ao estresse por meio de entrevistas e question\u00e1rios com pais e jovens e an\u00e1lise de marcadores biol\u00f3gicos nas coortes de Pelotas<\/a> que acompanham 20 mil crian\u00e7as nascidas em 1982, 1993, 2004 e 2015 no Sul do Brasil.<\/p>\n

Ambientes estressantes podem sobrecarregar pais e cuidadores, reduzindo sua capacidade de proporcionar acolhimento \u00e0s crian\u00e7as e aumentando o risco de pr\u00e1ticas parentais r\u00edspidas e inadequadas. Maus tratos podem vir \u00e0 tona em situa\u00e7\u00f5es como as de estresse intenso, uso de \u00e1lcool ou drogas, ou condi\u00e7\u00f5es criminais ou psiqui\u00e1tricas dos pais. No primeiro estudo desse g\u00eanero em um pa\u00eds em desenvolvimento, estamos examinando o estresse cr\u00f4nico entre m\u00e3es para determinar como essa condi\u00e7\u00e3o influencia as pr\u00e1ticas parentais e o desenvolvimento cognitivo e psicossocial da crian\u00e7a. Um mecanismo chave pelo qual o estresse pode afetar o desenvolvimento infantil \u00e9 atrav\u00e9s da desregula\u00e7\u00e3o do eixo HPA (Hipot\u00e1lamo-Pituit\u00e1ria-Adrenal). Avaliamos a ativa\u00e7\u00e3o cr\u00f4nica do eixo HPA usando medidas dos n\u00edveis de cortisol capilar em m\u00e3es e crian\u00e7as, para testar se os n\u00edveis desse marcador biol\u00f3gico do estresse s\u00e3o preditores da agressividade e do desenvolvimento sociocognitivo da crian\u00e7a. O\u00a0estudo PI\u00c1<\/a>\u00a0est\u00e1 avaliando se interven\u00e7\u00f5es de orienta\u00e7\u00e3o e apoio a pais com filhos pequenos podem evitar essa cadeia de eventos adversos.<\/p>\n
