Abstract

Developmental disability rates may vary by the season or month in which children are born. However, the seasonal mechanisms, such as climate, underlying these variations are unclear. Previous studies focused on high-latitude regions, leaving this climate hypothesis only partially tested. We analyzed rates of developmental disabilities in 3- to 5-year-old children from a tropical climate—South Florida—from 2004 to 2015 (N = 79,047) using a time-series analysis to identify peaks in diagnoses based on birth months. Children with speech impairments were more likely to be born in March, April, and September, a novel finding. Children with developmental delays were more likely to be born in September and October, consistent with studies in colder regions. In contrast to prior studies, there were no effects of birth month for language impairment or autism spectrum disorder. We highlight potential prenatal mechanisms that may contribute to the seasonal variations in some developmental disabilities.
在热带气候下,不同出生月份的发育残疾率不同
发育残疾率可能因孩子出生的季节或月份而异。然而,这些变化背后的季节机制,如气候,尚不清楚。先前的研究集中在高纬度地区,这一气候假说只得到了部分检验。我们分析了2004年至2015年热带气候——南佛罗里达州——3至5岁儿童的发育障碍率(N=79047),使用时间序列分析来确定基于出生月份的诊断峰值。一项新发现,有言语障碍的儿童更有可能在3月、4月和9月出生。发育迟缓的儿童更有可能在9月和10月出生,这与寒冷地区的研究一致。与之前的研究相比,出生月份对语言障碍或自闭症谱系障碍没有影响。我们强调了可能导致某些发育障碍季节性变化的潜在产前机制。

期刊介绍: The Journal of Special Education (JSE) is a multidisciplinary publication presenting primary research and scholarly reviews related to special education. The goal of this journal is to add to current scholarship and provide a sense of emerging directions in the field. Manuscripts initially are screened for (a) appropriateness of content for JSE, (b) adherence to guidelines specified in the APA publication manual, (c) readability of text, and (d) explicit statement of implications for the practice of special education.
