目标。社会经济地位是与健康相关的最强有力的社会因素之一，但随着时间的推移，社会经济地位如何影响儿童健康的动态仍不清楚。这项研究测试了儿童社会经济地位的各种模型(家庭收入的积累、变化、变化和关键时期)如何预测儿童时期最后一个时间点的健康结果。这是一项前瞻性的纵向研究，涉及6306名年龄在10岁至11岁之间的儿童，他们的家人从出生起每隔一年接受一次访谈。样本来自美国全国青少年纵向调查。在同一数据集中，还检查了4305名14至15岁儿童的复制样本。主要结果包括父母对哮喘的报告，以及限制活动和上学以及需要医生治疗的情况。家庭累计收入越低，患上限制儿童活动的疾病的几率就越高，而且这种疾病需要在10岁至11岁的时候接受医生的治疗。与收入变化或收入变化相比，家庭累计收入是更强的预测指标。早期家庭收入较低(0-5岁)与患有限制活动的疾病和10-11岁需要医生治疗的疾病的几率较高相关，与当前的社会经济地位无关。在14至15岁的样本中发现了相同的结果。这些研究结果表明，在整个童年时期，根据家庭收入积累社会经济地位比社会流动或社会经济地位的变化更重要，尽管可能有某些时期(早期生活)对健康有更大的影响。这些发现表明了儿童干预对于减少健康差距的重要性。
Objective. Socioeconomic status is one of the most robust social factors associated with health, but the dynamics of how socioeconomic status over time affects children's health remains unclear. This study tested how various models of childhood socioeconomic status (accumulation, change, variability, and critical periods of family income) would predict health outcomes at a final time point in childhood.Methods. This was a prospective, longitudinal study of 6306 children who were aged 10 to 11 years and whose families were interviewed every other year from birth onward. The sample came from the US National Longitudinal Survey of Youth Children. In the same data set, a replication sample of 4305 14- to 15-year-old children was also examined. Primary outcomes included parent report of asthma and conditions that limited activity and school and required physician treatment.Results. Lower cumulative family income was associated with higher odds for having a condition that limited childhood activities, as well as a condition that required treatment by a physician at ages 10 to 11. Cumulative family income was a stronger predictor than change in income or variability in income. Lower family income early in life (ages 0-5 years) was associated with higher odds for having a condition that limited activities and a condition that required treatment by a physician at ages 10 to 11, independent of current socioeconomic status. Findings were replicated in the 14- to 15-year-old sample.Conclusions. These findings suggest that the accumulation of socioeconomic status in terms of family income across childhood is more important than social mobility or variability in socioeconomic status, although there may be certain periods of time (early life) that have stronger effects on health. These findings suggest the importance of childhood interventions for reducing health disparities.
