Studies that have investigated the effect of nutritional counseling during the prenatal period on the follow-up outcomes of children at 6 mo have produced inconclusive results. The present study aimed to investigate the effect of nutritional counseling, based on the NOVA food classification, encouraging the consumption of fresh and minimally processed foods, with overweight adult pregnant women on infant growth at 6 mo of age. A randomized controlled trial with 195 pairs of pregnant overweight women and their infants at 6 mo of age was conducted in a Brazilian municipality. The pregnant women were allocated to the control group (CG) or intervention group (IG) at the beginning of the pregnancy. The IG received three sessions of nutrition counseling throughout the pregnancy. Linear regression models were used to investigate the effect of the nutritional counseling on infant growth. One hundred ninety-five mother–infant pairs with complete data were included (96 CG, and 99 IG). The mean ± SD infant weight (g) at 6 mo was 7856.1 ± 1.1, and length (cm) was 67.0 ± 2.9. There were no differences in maternal and newborn characteristics between the groups. In the linear regression models, the counseling had no effect on anthropometric parameters of the infants at 6 mo of age: weight-for-length -score (β 0.089 [95% CI −0.250; 0.427], = 0.61); length-for-age -score (β 0.032 [95% CI −0.299; 0.363], = 0.85); weight-for-age -score (β 0.070 [95% CI −0.260; 0.400], = 0.68); BMI-age -score (β 0.072 [95% CI −0.270; 0.414], = 0.68). There was no effect on infant growth at 6 mo of age after the nutritional counseling during pregnancy. Future studies are needed to confirm this hypothesis.

超重孕妇营养咨询对 6 个月时儿童生长的有效性：一项随机对照试验

调查产前营养咨询对 6 个月儿童随访结果影响的研究尚未得出结论。本研究旨在调查基于 NOVA 食品分类的营养咨询对超重成年孕妇食用新鲜和最低限度加工食品的影响，对 6 个月大的婴儿生长的影响。在巴西的一个城市进行了一项随机对照试验，受试者为 195 对超重孕妇及其 6 个月大的婴儿。孕妇在怀孕初期被分配到对照组（CG）或干预组（IG）。 IG 在整个怀孕期间接受了 3 次营养咨询。采用线性回归模型研究营养咨询对婴儿生长的影响。纳入了 195 对具有完整数据的母婴（96 CG 和 99 IG）。 6 个月时婴儿体重（g）的平均值±SD 为 7856.1 ± 1.1，身长（cm）为 67.0 ± 2.9。各组之间的产妇和新生儿特征没有差异。在线性回归模型中，咨询对 6 个月婴儿的人体测量参数没有影响：体重身长评分 (β 0.089 [95% CI -0.250; 0.427], = 0.61)；年龄别长度得分（β 0.032 [95% CI -0.299；0.363]，= 0.85）；年龄别体重评分（β 0.070 [95% CI -0.260；0.400]，= 0.68）； BMI 年龄评分（β 0.072 [95% CI -0.270；0.414]，= 0.68）。怀孕期间的营养咨询对6个月大的婴儿生长没有影响。需要未来的研究来证实这一假设。
