摘要

本研究旨在探讨在三级医院分娩的孕妇血清维生素B12浓度是否与胎盘重量和产妇社会人口学特征相关。这项横断面研究共纳入了497名孕龄达到37周的单胎孕妇。所有孕妇都通过一份关于营养和饮食习惯、孕期体重增加、产前补充多种维生素和社会人口特征的问卷进行评估。研究人员测量了孕妇的血清维生素B12水平,并在分娩后立即对她们的胎盘进行称重。约有79.5%的孕妇缺乏维生素B12,尽管63%的参与者报告在产前服用了复合维生素补充剂。家庭经济状况和孕前体重指数(BMI)被确定为与母亲维生素B12水平相关的重要因素。此外,家庭经济状况和母亲年龄是影响胎盘重量的重要因素。这项研究发现,维生素B12缺乏症在低收入孕妇中非常普遍。此外,它揭示了胎盘重量与家庭经济状况的关系。研究结果还强调,尽管产前补充多种维生素的比例相对较高,但维生素B12缺乏仍然是一个关键问题。胎盘重量与血清维生素B12浓度之间未发现有统计学意义的关系。需要进一步的大规模和前瞻性研究来确定母体维生素B12水平对胎盘重量的影响。

Associations Between Maternal Vitamin B12 Levels, Sociodemographic Factors and Placental Weight: A Cross-Sectional Analysis in a Tertiary Hospital.

This study aimed to investigate whether serum vitamin B12 concentration is associated with placental weight and maternal sociodemographic characteristics in pregnant women who delivered in a tertiary hospital. A total of 497 pregnant women with a single foetus who had achieved 37 weeks gestational age were included in this cross-sectional study. All pregnant women were evaluated via a questionnaire about nutrition and dietary habits, weight gain during pregnancy, antenatal multivitamin supplementation and sociodemographic features. The serum vitamin B12 levels were measured in pregnant women, and their placentas were weighed immediately after delivery. Vitamin B12 deficiency was observed in about 79.5% of pregnant women, despite 63% of participants reporting the use of antenatal multivitamin supplements. Household economic status and pre-pregnancy body mass index (BMI) were identified as significant factors associated with maternal vitamin B12 levels. Furthermore, household economic status and maternal age were found to be significant factors associated with placental weight. This study identified a high prevalence of vitamin B12 deficiency among pregnant women with low family incomes. Moreover, it revealed a relationship between placental weight and household economic status. The findings also highlight that despite a relatively high rate of antenatal multivitamin supplementation, vitamin B12 deficiency remains a critical issue. No statistically significant relationship between placental weight and serum vitamin B12 concentration has been detected. Further large-scale and prospective studies are needed to establish the effect of maternal vitamin B12 levels on placental weight.
