Data for earthquake-related alterations in physique among young children in developed countries is lacking. The Great East Japan Earthquake caused severe damage in Iwate, Miyagi, and Fukushima Prefectures in northeastern Japan.
We retrospectively obtained anthropometric measurements in nursery school from 40,046 (cohort 1, historical control) and 53,492 (cohort 2) children aged 3.5-4.5 years without overweight in October 2008, and in October 2010, respectively. At the time of the earthquake in March, 2011, children in cohort 1 had already graduated from nursery school; however, children in cohort 2 were still enrolled in nursery school at this time. We compared the onset of overweight at 1 year after the baseline between children enrolled in their school located in one of the three target prefectures versus those in other prefectures using a logistic regression model, with adjustment for sex, age, history of disease, and obesity index at baseline. Overweight was defined as an obesity index of >+15%, which was calculated as (weight minus sex- and height-specific standard weight)/sex- and height-specific standard weight.
The odds ratio (OR) for the onset of overweight in the three target prefectures was significant in cohort 2 (OR 1.25; 95% confidence interval [CI], 1.01-1.55) but not in cohort 1. When the two cohort were pooled (n = 93,538), the OR of the interaction term for school location × cohort was significant (OR 1.56; 95% CI, 1.09-2.23).
Incident overweight in young children was significantly more common in the three prefectures affected by the Great East Japan Earthquake than in other prefectures after the disaster.
发达国家缺乏有关幼儿地震相关身体变化的数据。东日本大地震给日本东北部的岩手县、宫城县和福岛县造成了严重破坏。
我们回顾性地获取了2008年10月40,046名（队列1，历史对照）和2010年10月53,492名（队列2）3.5至4.5岁无超重幼儿在幼儿园的人体测量数据。2011年3月地震发生时，队列1的儿童已经从幼儿园毕业；然而，队列2的儿童此时仍在幼儿园就读。我们使用逻辑回归模型比较了位于三个目标县之一的学校的儿童与其他县的儿童在基线后1年超重的发生率，并对性别、年龄、疾病史和基线肥胖指数进行了调整。超重定义为肥胖指数>+15%，肥胖指数计算公式为（体重减去性别和身高特定标准体重）/性别和身高特定标准体重。
队列2中三个目标县超重发生率的优势比（OR）显著（OR 1.25；95%置信区间[CI]，1.01-1.55），但队列1中不显著。当将两个队列合并（n = 93,538）时，学校位置×队列交互项的OR显著（OR 1.56；95% CI，1.09-2.23）。
东日本大地震受灾的三个县幼儿超重的发生率在灾后明显高于其他县。
