背景：一些干预措施，以改善认知的风险儿童已经提出。识别预测认知的关键变量对于指导这些干预措施是必要的。本研究进行了确定这些变量在乌干达儿童和指导这样的interventions.Methods：一个队列的89名健康儿童（45名女性）年龄在5至12岁，随后超过24个月，并有认知测试测量视觉空间处理，记忆，注意力和空间学习管理在基线，6个月和24个月。营养状况，儿童的教育水平，母亲的教育，社会经济地位和家庭环境的质量也在基线测量。一个多变量的纵向模型被用来确定24个月内认知的预测因素。结果：孩子的教育水平越高，记忆力越好（p = 0.03），注意（p = 0.005）和24个月内的空间学习得分（p = 0.05）;较高的营养分数预测更好的视觉空间处理（p = 0.002）和空间学习得分（p = 0.008）;家庭环境得分越高，记忆力得分越高结论：乌干达儿童的认知能力受教育程度、营养状况和家庭环境的影响。社区干预措施，以改善认知可能是有效的，如果他们针对多个社会经济变量。
Background: Several interventions to improve cognition in at risk children have been suggested. Identification of key variables predicting cognition is necessary to guide these interventions. This study was conducted to identify these variables in Ugandan children and guide such interventions.Methods: A cohort of 89 healthy children (45 females) aged 5 to 12 years old were followed over 24 months and had cognitive tests measuring visual spatial processing, memory, attention and spatial learning administered at baseline, 6 months and 24 months. Nutritional status, child's educational level, maternal education, socioeconomic status and quality of the home environment were also measured at baseline. A multivariate, longitudinal model was then used to identify predictors of cognition over the 24 months.Results: A higher child's education level was associated with better memory (p = 0.03), attention (p = 0.005) and spatial learning scores over the 24 months (p = 0.05); higher nutrition scores predicted better visual spatial processing (p = 0.002) and spatial learning scores (p = 0.008); and a higher home environment score predicted a better memory score (p = 0.03).Conclusion: Cognition in Ugandan children is predicted by child's education, nutritional status and the home environment. Community interventions to improve cognition may be effective if they target multiple socioeconomic variables.
