探讨营养摄入与颈椎重塑的直接关系。纵向描述性设计。一个中西部城市的母胎医学诊所。47名怀孕的非裔美国妇女。参与者在妊娠19至24周和27至29周时完成Block简短的食物频率问卷，并在妊娠19至21周、23至25周、27至29周、31至33周和35至37周时进行定量超声衰减估计。轨迹混合模型在我们的样本中确定了两个亚群：高危人群（n = 36）和低风险人群（n = 11）。风险较低组的参与者比风险较高组的参与者摄入了钙、维生素A、叶酸、维生素E、锌和维生素D的膳食参考摄入量（DRI）。低风险组中摄入推荐DRI维生素E的参与者比例是风险组中女性比例的两倍（分别为82%和44%，p= 0.004）。低风险组的平均钙摄入量几乎是风险组的1.3倍（p = 0.05），锌摄入量是风险组的1.5倍（p =0.04）。医生可以告诉妇女，某些营养物质，特别是锌、钙和维生素E，对子宫颈的健康很重要，可以抑制宫颈过早重塑，从而有助于预防早产。营养摄入锌、钙或维生素E不足的非裔美国孕妇发生过早颈椎重塑的风险更高。
To examine the direct relationship between nutrient intake and cervical remodeling. Longitudinal descriptive design. Maternal-fetal medicine clinic in a Midwestern urban city. Forty-seven pregnant African American women. Participants completed the Block brief food frequency questionnaire at 19 to 24 weeks and 27 to 29 weeks gestation and had quantitative ultrasound attenuation estimates at 19 to 21 weeks, 23 to 25 weeks, 27 to 29 weeks, 31 to 33 weeks, and 35 to 37 weeks gestation. Trajectory mixture models identified two subpopulations within our sample: at-risk (n = 36) and less-risk (n = 11) for premature cervical remodeling. More participants in the less-risk group consumed the dietary reference intake (DRI) for calcium, vitamin A, folate, vitamin E, zinc, and vitamin D than in the at-risk group. The percentage of participants in the less-risk group who consumed the recommended DRI for vitamin E was twice the percentage of women in the at-risk group (82% and 44%, respectively, p=.004). Mean intake of calcium was almost 1.3 times more (p = 0.05) and for zinc was 1.5 times more (p =0.04) in the less-risk group than in the at-risk group. Practitioners can inform women that certain nutrients, particularly zinc, calcium, and vitamin E, could be important to the health of the cervix and inhibit premature cervical remodeling, which in turn may help to prevent preterm birth. Pregnant African American women with poor nutritional intake of zinc, calcium, or vitamin E were at higher risk for premature cervical remodeling.
