This study aimed to evaluate the sequential changes in the proportion of anemia among young women over eight years after the Great East Japan Earthquake in 2011 using a prospective study of the Fukushima Health Management Survey. This study focused on the women aged between 20 and 44 who lived in the evacuation area of the nuclear power plant accident. The yearly age-adjusted proportion of anemia was accessed with data between July 2011 and March 2019. A total of 9,198 women participated in the health checkup in 2011, albeit the participation was decreased to 1,241 in 2018. The age-adjusted proportion of anemia was 16.7% in 2012 and then declined after 2013 (p with Cochran-Armitage trend test = 0.03). The multivariate regression analysis identified < 23 kg/m of body mass index (BMI), no history of smoking, and no habitual alcohol use as independent baseline characteristics predictive of temporality anemic condition after the disaster (Adjusted odds ratios [95% confidence interval]; 1.98 [1.43-2.74], 1.85 [1.21-2.83], and 1.42 [1.07-1.90], respectively). Thus, women with low BMI and healthier habits might risk temporarily anemic status after the disaster. Our findings signal the importance of preventing anemia in young women after the disaster.
本研究旨在通过福岛健康管理调查的前瞻性研究，评估 2011 年东日本大地震后 8 年期间年轻女性贫血比例的连续变化。本研究关注居住在核电站事故疏散区、年龄在 20 至 44 岁之间的女性。通过 2011 年 7 月至 2019 年 3 月的数据，评估每年年龄调整后贫血的比例。共有 9198 名女性参加了 2011 年的健康检查，但到 2018 年，参加人数减少到 1241 人。2012 年，年龄调整后的贫血比例为 16.7%，之后在 2013 年之后下降（Cochran-Armitage 趋势检验 p = 0.03）。多变量回归分析确定 <23 kg/m2 的体重指数（BMI）、无吸烟史和无习惯性饮酒是灾难后暂时性贫血状况的独立基线特征（调整后的优势比 [95%置信区间]；1.98 [1.43-2.74]、1.85 [1.21-2.83]和 1.42 [1.07-1.90]）。因此，BMI 较低且生活习惯更健康的女性可能会在灾难后面临暂时性贫血的风险。我们的研究结果表明，在灾难后预防年轻女性贫血的重要性。
