健康差异的观点表明，低家庭收入状况是认知功能不良的一个危险因素。生物系统的观点表明，睡眠不足和压力反应系统功能低下也是危险因素。这些观点很少被整合来测试社会文化和生物变量的倍增风险或保护作用。我们研究了家庭收入，儿童睡眠和呼吸性窦性心律失常反应性（RSA反应性，索引副交感神经系统反应性）之间的相互作用，以预测学龄儿童的认知表现。参与者为282名儿童（146名男孩; 35%为非洲裔美国人，65%为欧洲裔美国人;法师= 9.42岁，SD= 0.71）。母亲报告了家庭收入。儿童的睡眠质量（效率）和持续时间（分钟）通过一周的活动记录仪进行评估。在实验室中评估了儿童对注意力要求和令人沮丧的星星追踪挑战的RSA反应。儿童完成了标准化的认知评估，检查注意力，处理速度和结晶认知功能。研究结果表明，更佳的睡眠效率和RSA反应性相互作用，以防止认知能力低下，特别是对低收入家庭的儿童。研究结果建立在文献的基础上，表明生物系统和社会经济变量之间的相互作用是理解儿童认知表现的关键。© 2014 Wiley Periodicals，Inc.

A health disparities view suggests that low family income status acts as a risk factor for poor cognitive functioning. A biosystems view suggests that poor sleep and poor stress response system functioning are also risk factors. These views are rarely integrated to test multiplicative risk or protective effects from social–cultural and biological variables. We investigated interactions among familial income, children's sleep and respiratory sinus arrhythmia reactivity (RSA reactivity, indexing parasympathetic nervous system reactivity) in the prediction of cognitive performance of school‐aged children. Participants were 282 children (146 boys; 35% African American and 65% European American;Mage = 9.42 years,SD= .71). Mothers reported on family income. Children's sleep quality (efficiency) and duration (minutes) were assessed via a week of actigraphy. Children's RSA reactivity to an attention demanding and frustrating star tracing challenge was assessed in the lab. Children completed standardized cognitive assessments examining attention, processing speed, and crystallized cognitive functioning. Findings show that more optimal sleep efficiency and RSA reactivity interact to confer protection against poor cognitive performance, particularly for children from lower income homes. Results build on the literature and suggest that interactions between biological systems and socioeconomic variables are key for understanding children's cognitive performance. © 2014Wiley Periodicals, Inc.
