To investigate the effects of socioeconomic changes from birth to 11 years of life on emotional, conduct, and attentional/hyperactivity problems in 15-year-old adolescents, from the 1993 Pelotas (Brazil) birth cohort study.
The original cohort was composed of 5,249 hospital-born children whose mothers answered a questionnaire. We conducted interviews with 87.5% and 85.7% of the original cohort in 2004-2005 and 2008, respectively. We divided family income changes into nine possible categories based on two assessment points (birth and 11 years of age) and three income levels. To assess the psychopathology of the adolescents at 15 years of age, 4,423 mothers answered the Strengths and Difficulties Questionnaire.
Adolescents who were always poor or who became poor between birth and 11 years of age had greater conduct problems at 15 years of age. There was no consistent association between poverty and emotional and attentional/hyperactivity problems.
The effects of income change were more specific to conduct problems than to emotional and attentional/hyperactivity problems, similar to what has been previously described in developed countries.
从 1993 年巴西佩洛塔斯出生队列研究中，调查从出生到 11 岁期间的社会经济变化对 15 岁青少年情绪、行为和注意力/多动问题的影响。
原始队列由 5249 名在医院出生的儿童组成，其母亲回答了一份问卷。我们分别于 2004-2005 年和 2008 年对原始队列中的 87.5%和 85.7%进行了访谈。我们根据两个评估点（出生和 11 岁）和三个收入水平，将家庭收入变化分为九个可能的类别。为了评估 15 岁青少年的精神病理学，4423 名母亲回答了《长处和困难问卷》。
在 15 岁时，一直贫困或在出生到 11 岁之间变得贫困的青少年有更大的行为问题。贫困与情绪和注意力/多动问题之间没有一致的关联。
与发达国家之前的描述类似，收入变化的影响对行为问题比情绪和注意力/多动问题更具体。
