Background No previous study has examined the effect of maternal hypothyroidism on a broad spectrum of cardiovascular disease (CVD) endpoints in the offspring. Methods A nationwide population-based cohort study based on the linkage of several Danish nationwide registries was conducted to explore whether maternal hypothyroidism is associated with offspring's CVD. Altogether 1,041,448 singletons born between the 1st of January 1978 and the 31st of December 1998 were investigated from the age of 8 years to the 31st of December 2016. Exposure was maternal diagnosis of hypothyroidism across lifespan and the outcome of interest was a CVD diagnosis in the offspring. Cox regression models were performed to estimate the hazard ratios (HRs) of CVD. Results Offspring born to mothers with hypothyroidism had an increased risk of CVD (hazard ratios (HR)=1.23, 95% confidence interval (CI): 1.12-1.35), and of several subcategories of CVD including hypertension, arrhythmia, and acute myocardial infarction in offspring. The magnitude of association was the most pronounced in an exposure occur during pregnancy (HR=1.71, 95% CI: 1.10-2.67), which is consistent across all the subgroup analysis, including sibling analysis. Conclusions Maternal hypothyroidism is associated with an increased risk of CVD in offspring. Thyroid hormone insufficiency during pregnancy may predominantly contribute to the observed associations; however, the effects of a shared genetic background and a time-stable familial environment/lifestyle factors cannot be excluded.

母体甲状腺功能减退症与后代心血管疾病的关系。

背景 以前没有研究检查过母体甲状腺功能减退对后代心血管疾病 (CVD) 终点的影响。方法 进行了一项基于丹麦全国登记处关联的全国人群队列研究,以探讨母体甲状腺功能减退是否与后代 CVD 相关。从 8 岁到 2016 年 12 月 31 日,对 1978 年 1 月 1 日至 1998 年 12 月 31 日期间出生的 1,041,448 名单身人士进行了调查。暴露是母亲在整个生命周期中诊断出的甲状腺功能减退症,感兴趣的结果是在后代。进行 Cox 回归模型以估计 CVD 的风险比 (HR)。结果 患有甲状腺功能减退症的母亲所生的后代患心血管疾病的风险增加(风险比 (HR)=1. 23, 95% 置信区间 (CI):1.12-1.35),以及 CVD 的几个亚类,包括后代的高血压、心律失常和急性心肌梗塞。关联程度在怀孕期间发生的暴露中最为明显(HR = 1.71,95% CI:1.10-2.67),这在所有亚组分析(包括兄弟姐妹分析)中都是一致的。结论 母体甲状腺功能减退与后代 CVD 风险增加有关。怀孕期间甲状腺激素不足可能主要促成观察到的关联;然而,不能排除共同的遗传背景和稳定的家庭环境/生活方式因素的影响。关联程度在怀孕期间发生的暴露中最为明显(HR = 1.71,95% CI:1.10-2.67),这在所有亚组分析(包括兄弟姐妹分析)中都是一致的。结论 母体甲状腺功能减退与后代 CVD 风险增加有关。怀孕期间甲状腺激素不足可能主要促成观察到的关联;然而,不能排除共同的遗传背景和稳定的家庭环境/生活方式因素的影响。关联程度在怀孕期间发生的暴露中最为明显(HR = 1.71,95% CI:1.10-2.67),这在所有亚组分析(包括兄弟姐妹分析)中都是一致的。结论 母体甲状腺功能减退与后代 CVD 风险增加有关。怀孕期间甲状腺激素不足可能主要促成观察到的关联;然而,不能排除共同的遗传背景和稳定的家庭环境/生活方式因素的影响。怀孕期间甲状腺激素不足可能主要促成观察到的关联;然而,不能排除共同的遗传背景和稳定的家庭环境/生活方式因素的影响。怀孕期间甲状腺激素不足可能主要促成观察到的关联;然而,不能排除共同的遗传背景和稳定的家庭环境/生活方式因素的影响。
