To examine the consistency and adequacy of nutritional intake in a population of Black women in the second and third trimesters of pregnancy.
This was a longitudinal descriptive study. Data were collected from women with low-risk pregnancies at 22- to 24-week prenatal visits and two subsequent visits.
Participants were recruited from urban prenatal clinics in one city in the Northeastern United States.
Pregnant women who self-identified as Black (N = 195).
A 24-hour diet recall was obtained at each of the three study time points. Food models and measuring cups were used to improve the accuracy of portion size reporting. Data from diet recalls were manually entered in Food Processor software to compute nutritional content.
A linear mixed-effects model was used to examine dietary intake. Dietary patterns were stable from the second to the third trimesters, and caloric intake was inadequate. Women met minimal daily requirements for carbohydrate and protein intake, but the overall percentages of fat, protein, and carbohydrates indicated that additional calories needed to come from protein. Although more than 80% of women regularly took prenatal vitamins, micronutrient and fiber intake were consistently inadequate.
Prenatal care to help women identify foods that are rich in fiber, protein, and micronutrients is important for the health of women and newborns. Knowing that nutritional intake is consistently inadequate, nurses can counsel pregnant women whenever they have contact with them to attempt to improve nutritional intake and make women aware of inexpensive nutrient sources.
研究孕期第二和第三阶段黑人女性群体营养摄入的一致性和充足性。
这是一项纵向描述性研究。数据收集自低风险妊娠女性,在其孕22至24周产前检查及随后两次检查时进行。
参与者招募自美国东北部一个城市的城市产前诊所。
自我认定为黑人的孕妇(N = 195)。
在三个研究时间点的每一个时间点都进行了24小时饮食回顾。使用食物模型和量杯来提高食物份量报告的准确性。饮食回顾数据手动录入Food Processor软件以计算营养成分。
使用线性混合效应模型来研究饮食摄入情况。从孕期第二阶段到第三阶段,饮食模式稳定,但热量摄入不足。女性满足了碳水化合物和蛋白质摄入的每日最低需求,但脂肪、蛋白质和碳水化合物的总体百分比表明,额外的热量需要来自蛋白质。尽管超过80%的女性定期服用产前维生素,但微量营养素和纤维摄入一直不足。
提供产前护理以帮助女性识别富含纤维、蛋白质和微量营养素的食物,对女性和新生儿的健康很重要。鉴于营养摄入一直不足,护士在每次与孕妇接触时都可以为其提供咨询,以尝试改善营养摄入,并让女性了解廉价的营养来源。
