DESCRIPTION (provided by applicant): The overall goal of this secondary data analysis is to estimate the impact of adolescent pregnancy on maternal and infant anthropometric and micronutrient status in a nutritionally deficient population in rural Nepal. The two data sets that will be used to address these questions derive from two maternal micronutrient supplementation trials undertaken between 1992 and 2000. Together, these trials followed 22,000 pregnancies prospectively from the middle of the first trimester through 6 months postpartum. Approximately 5,000 of these pregnancies were among girls under 20 years of age. In a sample of about 3,000 pregnancies (500 adolescents), a more detailed protocol was followed. The specific aims are to examine whether nutritional status in early pregnancy, 3rd trimester and 3 months postpartum is the same for adolescents as for older pregnant women of the same parity. Measures of nutritional status include weight, body mass index, mid upper arm circumference, arm muscle area and arm fat area, a history of night blindness in pregnancy, hemoglobin and serum retinol. For measures such mid upper arm circumference, the change during pregnancy and from pregnancy through postpartum will also be examined. Among live born offspring, the specific aims are to examine whether adolescents' offspring have similar nutritional status to that of the offspring of older women of the same parity. Measures of nutritional status at birth include weight, length, head, chest and mid upper arm circumference. Growth of these infants through 6 months of age will also be examined, as will hemoglobin and serum retinol at 3 months of age.

描述（由申请人提供）：该二次数据分析的总体目标是估计青少年怀孕对尼泊尔农村农村营养缺乏人口中母体和婴儿人体测量值和微量营养素状态的影响。将用于解决这些问题的两个数据集源自1992年至2000年间进行的两项孕产妇微量营养素补充试验。这些试验共同遵循了22,000次怀孕，从前期妊娠中期到产后6个月。这些怀孕中约有5,000岁是20岁以下的女孩。在大约3,000例怀孕（500名青少年）的样本中，遵循了更详细的方案。具体目的是检查怀孕初期，三个月和产后3个月的营养状况是否与同等奇偶校验的老年孕妇相同。营养状况的措施包括体重，体重指数，上臂圆周，手臂肌肉区域和手臂脂肪区域，妊娠夜失明的病史，血红蛋白和血清视网膜视网膜。对于诸如上臂围此类措施，还将检查怀孕期间的变化，从怀孕到产后。在出生的后代中，具体的目的是检查青少年的后代是否具有与同等奇偶校验的老年妇女的后代相似的营养状况。出生时营养状况的度量包括体重，长度，头部，胸部和上臂围。这些婴儿在6个月大时的生长也将被检查，三个月大时血红蛋白和血清视黄醇也将进行检查。
