Utilizaron cuestionarios para evaluar los síntomas de THDA en los niños, el consumo de tabaco durante el embarazo, síntomas de trastorno conductual y adversidad familiar en una muestra de población de 1.452 parejas de mellizos.
Los factores genéticos están implicados en la mayoría de casos del trastorno, tal como explican los autores. Sin embargo, advirtieron una significativa asociación entre el consumo de tabaco durante la gestación y el desarrollo de síntomas del THDA en los niños.
