Associations between 25OHD status and pregnancy outcomes.

Adjusted for maternal age, parity, ethnicity, education, body mass index, smoking exposure, physical activity, pre-existing diabetes and/ or hypertension, neonatal sex. 25OHD inadequacy = 25OHD ≤75nmol/l; 25OHD adequacy = 25OHD>75nmol/l. The values in bold indicate pa Data are presented as Odds Ratio (95% Confidence Interval), unless otherwise indicated.b Data are presented as β regression coefficient (95% Confidence Interval)c Included both emergency and elective caesarean sections.25OHD = 25-hydroxyvitamin D; FG = fasting glucose; 2HPPG = 2-hour postprandial glucose; GDM = gestational diabetes mellitusAssociations between 25OHD status and pregnancy outcomes.

本研究已针对产妇年龄、产次、种族、教育程度、体质量指数、吸烟暴露、体力活动、既往糖尿病和/或高血压及新生儿性别进行混杂校正。25-羟维生素D（25-hydroxyvitamin D，以下简称25OHD）不足定义为25OHD ≤75nmol/L，充足定义为25OHD＞75nmol/L。标粗数值对应的结果以比值比（95%置信区间）呈现，另有说明者除外。b 注：数据以β回归系数（95%置信区间）呈现。c 本研究纳入急诊剖宫产与择期剖宫产病例。其中：25OHD为25-羟维生素D；FG为空腹血糖（fasting glucose）；2HPPG为餐后2小时血糖（2-hour postprandial glucose）；GDM为妊娠期糖尿病（gestational diabetes mellitus）。25羟维生素D水平与妊娠结局的关联。
