Background Socioeconomic gradients in health exist in Canada. Although multiple Canadian area-based socioeconomic measures (ABSM) have been developed, none have been specifically validated against pediatric outcomes. Our objective was to compare the strength of association between key pediatric health outcomes and a number of ABSM, including income quintile. Methods This was a retrospective cross-sectional assessment of the association between socioeconomic status (SES) measured by ABSM and 20 specific pediatric health outcomes. Data from the Manitoba Population Research Data Repository were used for residents aged 0–19 years from 2010 to 2015. Outcomes included birth-related events (e.g. mortality), vaccination uptake, hospitalizations, and teen pregnancy. Regression goodness of fit was used to assess the strength of individual associations. Inequality was measured by slope index of inequality (SII) and relative index of inequality (RII). Results Overall, 19 of 20 outcomes had socioeconomic gradients identified by SII and RII. The multidimensional CAN-Marg indices had the best explanatory power in standard regression models. The simplest ABSM—income quintile—detected 16 of 19 confirmed inequalities, more than any other single measure. Conclusions At all ages, many pediatric health outcomes in Manitoba were associated with significant socioeconomic inequalities; while income quintile detected most, CAN-Marg composite indices had the best explanatory power.

使用基于地区的社会经济措施评估儿童健康结果的不平等：一项使用曼尼托巴省人口数据的回顾性横断面研究

背景 加拿大存在健康方面的社会经济梯度。尽管已经开发了多种基于加拿大地区的社会经济措施 (ABSM)，但没有一项专门针对儿科结果进行验证。我们的目标是比较关键儿科健康结果与许多 ABSM（包括收入五分之一）之间的关联强度。方法 这是对 ABSM 测量的社会经济地位 (SES) 与 20 项特定儿科健康结果之间关联的回顾性横断面评估。曼尼托巴人口研究数据库中的数据用于 2010 年至 2015 年 0-19 岁的居民。结果包括出生相关事件（例如死亡率）、疫苗接种、住院和少女怀孕。回归拟合优度用于评估个体关联的强度。不平等是通过不平等的斜率指数（SII）和不平等的相对指数（RII）来衡量的。结果 总体而言，20 个结果中有 19 个具有 SII 和 RII 确定的社会经济梯度。多维 CAN-Marg 指数在标准回归模型中具有最好的解释力。最简单的 ABSM（收入五分之一）检测到 19 个已确认的不平等中的 16 个，比任何其他单一衡量指标都多。结论 在所有年龄段，曼尼托巴省的许多儿科健康结果都与显着的社会经济不平等有关；虽然收入五分位数检测最多，但 CAN-Marg 综合指数的解释力最好。多维 CAN-Marg 指数在标准回归模型中具有最好的解释力。最简单的 ABSM——收入五分之一——检测到 19 个已确认的不平等中的 16 个，比任何其他单一衡量指标都多。结论 在所有年龄段，曼尼托巴省的许多儿科健康结果都与显着的社会经济不平等有关；虽然收入五分位数检测最多，但 CAN-Marg 综合指数的解释力最好。多维 CAN-Marg 指数在标准回归模型中具有最好的解释力。最简单的 ABSM（收入五分之一）检测到 19 个已确认的不平等中的 16 个，比任何其他单一衡量指标都多。结论 在所有年龄段，曼尼托巴省的许多儿科健康结果都与显着的社会经济不平等有关；虽然收入五分位数检测最多，但 CAN-Marg 综合指数的解释力最好。
