A retrospective study on the effect of intensive nutrition counseling on weight gain of pregnant women and birth weight of their infants was conducted at an outpatient clinic by comparing one group of 86 women who attended only a nutrition class with another group of 114 women who attended the class plus multiple counseling sessions on appropriate weight gain and nutrient intake. The women receiving the counseling on an average gained 2.5 kg more weight, had fewer low-birth-weight infants (4% vs. 13%), and had infants weighing 100 gm more at birth. That indicates that intensive nutrition counseling results in a superior outcome of pregnancy. When the cost of intensive neonatal care for six infants was compared with the cost of nutrition counseling, a benefit-to-cost ratio of 1:5 was found.
在一家门诊诊所进行了一项关于强化营养咨询对孕妇体重增加及其婴儿出生体重影响的回顾性研究。研究将一组仅参加营养课程的86名女性与另一组参加该课程并接受了多次关于适当体重增加和营养摄入咨询的114名女性进行了比较。接受咨询的女性平均体重增加了2.5千克，低体重婴儿较少（4%对13%），且婴儿出生时体重平均重100克。这表明强化营养咨询能带来更好的妊娠结局。当将六名婴儿的强化新生儿护理成本与营养咨询成本进行比较时，发现效益成本比为1:5。
