| Abstract

Adolescent pregnancies are a concern worldwide. This study investigated how pregnancy and lactation during adolescence affects the growth and nutritional status of young mothers in rural developing country settings. A prospective cohort study was conducted among 12-19 year old primigravidae (n=229) and never-pregnant adolescents (n=458) matched on age and time since menarche using a ratio of 1:2. Pregnant adolescents were measured for anthropometry in the early first trimester of pregnancy and at 6-months postpartum. Never-pregnant girls were assessed within a week of these assessments. A large proportion of adolescents (49%) were stunted (height-for-age z-score<-2) and underweight (40%) (weight-for-age z-score<-2), but not thin (∼10%) (BMI-for-age th</super> centile). Pregnant girls did not gain height during the follow-up period, whereas never-pregnant adolescents increased their stature by 0.36±0.04 cm/y, adjusting for confounders. While pregnant adolescents lost weight, BMI, and MUAC by 6-months postpartum, never-pregnant counterparts gained in each ponderal dimension over a one-year period (all p<0.01). Similarly, annual losses in TSF and % body fat were greater and gain in SSF was less among pregnant girls compared to never-pregnant counterparts (p<0.01). Pregnant girls, irrespective of their birth outcome, did not gain in stature. Pregnant adolescents whose infants survived the neonatal period lost weight, BMI, mid-upper arm circumference, and % body fat by 6-mo postpartum, whereas those who experienced a fetal loss or neonatal death did not change in any of the measurements over a year period (all p<0.05). Changes in maternal anthropometry did not differ between adolescents who had normal versus low birth weight infants, term versus preterm delivery, and small-for-gestational age versus normal sized at birth infants. Pregnancy and lactation during adolescence appeared to cease linear growth and resulted in weight loss and depletion of fat and lean body mass of young girls. Cessation of linear growth occurred in all pregnant teenagers regardless of their birth outcome. However, weight loss and depletion of fat and lean body mass were more pronounced among adolescents whose infants survived the neonatal period, which may be due to the increased nutritional demands of late pregnancy and lactation.
