Distribution of Vitamin D Levels in Women of Different Ages in Early Pregnancy
-
摘要:
目的 分析昆明市妇幼保健院妊娠早期妇女血清25-羟维生素D(25OHD)含量水平,并探究其与妊娠年龄相关性,为计划妊娠妇女维生素D合理补充提供建议。 方法 选取2018年1月至2020年12月昆明市妇幼保健院产检4283例妊娠早期妇女作为观察对象,分为16~20岁组(97例),21~25岁组(999例),26~30岁组(1894例),31~35岁组(930例),36~40岁组(303例),41~45岁组(60例)6个组。对6组妊娠期妇女的血清25-羟维生素D含量进行比较。 结果 4 283名妊娠期妇女血清25OHD含量平均水平处于不足状态,16~20岁组25OHD含量相对较低。 结论 妊娠年龄与血清25OHD水平存在相关性,低龄妊娠组血清25OHD水平相对较低,需对低龄妊娠妇女25OHD水平进行早期筛选及干预。 Abstract:Objective To analyze the level of serum 25-hydroxyvitamin D(25OHD) in women of early pregnancy in Kunming Maternal and Child Health Hospital, and to explore the correlation between the level and gestational age, so as to provide suggestions for reasonable vitamin D supplement for women planning pregnancy. Methods From January 2018 to December 2020, 4283 pregnant women in Kunming Maternal and Child Health Hospital were selected as the observation subjects. They were divided into 16 to 20 years old group(97 cases), 21 to 25 years old group(999 cases), 26 to 30 years old group(1894 cases), 31 to 35 years old group(930 cases), 36 to 40 years old group(303 cases). 41 to 45 years old group(60 cases) 6 groups. The serum 25- hydroxyvitamin D levels of 6 groups of pregnant women were compared. Results The average level of vitamin D in 4283 pregnant women was lower than normal, and the level of 25OHD in 16~20 years old group was the lowest. Conclusion Gestational age is correlated with serum 25OHD level, and the serum 25OHD level in the low gestational age group is relatively low, which requires early screening and intervention for the level of 25OHD in the low gestational age women. -
