The spatial variability of three indicators of learning and developmental disability (LDD) was assessed for Cape Cod, Massachusetts. Maternal reports of receiving special education services, attention deficit hyperactivity disorder, and educational attainment were available for a birth cohort from 1969-1983. Using generalized additive models and residential history, maps of the odds of LDD were produced that also controlled for known risk factors. While results were not statistically significant, they suggest that children living in certain parts of Cape Cod were more likely to have a LDD. The spatial variation may be due to variation in the physical and social environment.
对马萨诸塞州科德角的三种学习和发育障碍（LDD）指标的空间变异性进行了评估。1969 年至 1983 年的出生队列提供了母亲接受特殊教育服务、注意力缺陷多动障碍和教育程度的报告。使用广义加性模型和居住史，制作了 LDD 可能性的地图，同时还控制了已知的风险因素。虽然结果没有统计学意义，但它们表明，居住在科德角某些地区的儿童更有可能患有 LDD。空间变化可能是由于物理和社会环境的变化。
