SERRA, Camila Denise  and  GOMEZ, Eliana Daniela. Evaluation of gestational weight gain in adolescent pregnancy at a state hospital’s obstetric care. Diaeta [online]. 2018, vol.36, n.165, pp.08-15. ISSN 1852-7337.

Introduction: in Argentina, adolescent pregnancy represents 15% of total births. Despite this high prevalence, knowledge and specific recommendations for this population group are low. Adolescent mothers usually have more weight gain than recommended, increasing the risk of obstetric and neonatal complications. Objective: to evaluate the gestational weight gain in adolescent pregnancy following recommendations by the Institute of Medicine 2009. Methods: a cross-sectional observational study was carried out in adolescents with single pregnancies in immediate puerperal period, between August 2017 and January 2018. The pre-pregnancy BMI and the gestational weight gain were studied and compared to age, medical history and obstetric complications. Results: a total of 89 adolescents averaged age 17 ± 1.54 were evaluated; only 4.49% of the sample corresponded to mothers aged under 15. The pre-pregnancy BMI was: underweight 6.74%, normal weight 71.91%, overweight 13.48% and obesity 7.87%. 22.47%, 31.46% and 46.07% had a lower, appropriate and excessive weight gain respectively. 66.67% of underweight adolescents showed a lower weight gain, while the overweight ones exceeded the recommendations in 57.89% of cases. Within total obese, 71,42% presented obstetric complications. Conclusions: nearly 70% of adolescent mothers had an inappropriate weight gain. The adolescents who started the gestation with underweight gained less weight than recommended, and the ones with overweight gained more weight than the one recommended by the guidelines. Lastly, it is worth highlighting the development of obstetric complications in obese adolescents.
