To compare developmental markers and dietary intake of infants born to lower socioeconomic adolescent and adult mothers.
Sixty-one adolescent (age 14-18 years) and 60 adult (age 22-28 years) mothers met inclusion criteria of comparable socioeconomic status, age range, urban/rural residence, and distribution of infants by gender.
SAMPLE/SETTING: Adolescent subjects were recruited in last trimester and adult mothers postpartum. Interviews were conducted when infants were about 6 and 12 months of age. Data included age of occurrence for eight markers, age at adding complementary foods, two 24-h dietary recalls, and two measurements of growth.
Adolescent mothers reported a significantly earlier age at which the infant "holds a spoon by self" and "drinks alone from a trainer cup." Six other markers were not significantly different between groups. Adolescent mothers fed cereal significantly earlier than did adult mothers, but there were no significant differences for fruit, vegetables, and meat. At 12 months, infants of adolescents had intakes of vitamin D and iron which were < 100% of recommended allowances, as did infants of adult mothers for vitamin D, iron, and zinc. Dietary fat was significantly higher at 6 and 12 months and vitamin C was lower at 12 months for infants of adolescents compared to the adult group.
Compared to adult mothers, adolescent mothers reported earlier mean ages for developmental markers related to self-feeding, and introduced cereal earlier. In each group, selected nutrient intakes decreased from recommended amounts in the 6-12-month period. Fat intakes were significantly different between groups at 6 and 12 months.
比较社会经济地位较低的青少年母亲和成年母亲所生婴儿的发育指标及饮食摄入情况。
61名青少年（14 - 18岁）母亲和60名成年（22 - 28岁）母亲符合社会经济地位、年龄范围、城乡居住情况及婴儿性别分布可比的纳入标准。
样本/背景：青少年受试者在孕晚期招募，成年母亲在产后招募。当婴儿约6个月和12个月大时进行访谈。数据包括八项发育指标出现的年龄、添加辅食的年龄、两次24小时饮食回顾以及两次生长测量。
青少年母亲报告婴儿“自己拿勺子”和“用训练杯独自喝水”的年龄明显更早。其他六项指标在两组之间无显著差异。青少年母亲比成年母亲更早开始喂谷类食物，但在水果、蔬菜和肉类喂养方面无显著差异。在12个月时，青少年母亲所生婴儿的维生素D和铁摄入量低于推荐摄入量的100%，成年母亲所生婴儿的维生素D、铁和锌摄入量也是如此。与成年组相比，青少年母亲所生婴儿在6个月和12个月时的膳食脂肪含量显著更高，在12个月时维生素C含量更低。
与成年母亲相比，青少年母亲报告与自主进食相关的发育指标的平均年龄更早，且更早引入谷类食物。在每组中，6至12个月期间选定营养素的摄入量均低于推荐量。两组在6个月和12个月时的脂肪摄入量存在显著差异。
