OBJECTIVE: To describe morbidity
in low birth weight and normal weight infants and their
association with risk factors. MATERIAL AND METHODS: A
retrospective and comparative, observational study was made
at the Neonatal Intensive Care Unit of the Hospital Español
de México. Maternal variables (history of abortions, type
of complications and intergeneric period) and neonate
(birth weight, gender, gestational age, intrauterine growth
restriction, respiratory distress, Apgar and type of
complications) were evaluated. Descriptive, bivariate and
multivariate analysis were performed with the normal weight
and low weight groups. RESULTS: We registered 248 newborns:
53.6% male and 46.4% female were included. In 14.5% with
low weight and 33.1% presented respiratory difficulty.
63.0% of the mothers had complications during pregnancy.
Infants with respiratory distress had an OR of 3.85 (CI 95%
1.09-13.55, p = 0.036) and an intrauterine restriction of
OR of 861.99 (CI 95% 86.90-8550.32, p = 0.000). CONCLUSION:
Low birth weight is associated with the presence of
respiratory distress and intrauterine
restriction.

BACKGROUND: Obesity and overweight
in pregnancy have a significant impact in fetal
development. However, this association remains
controversial. OBJECTIVE: assess the association between
maternal preconception body mass index (BMI) and the
newborn nutritional status. MATERIAL AND METHODS:
Prospective study, where singleton births were included.
Newborns were classified according to their mother's
preconception BMI and anthropometric measurements were
taken to evaluate the newborn's nutritional status. For the
statistical análisis we present descriptive statistics for
the main variables and we fitted lineal regression models.
RESULTS: A total of 492 dyads were included, 30.7% of the
mothers had overweight or obesity. We found that mothers
with overweight or obesity tend to have products with
higher birth weight (?=0.01; IC95% (0.002,0.019) p0.015),
increased arm circumference (?=0.02; IC95% (0.001,0.045)
p0.037) and a tendency of lower length at birth (?=0.002;
IC95% (-0.003,0.0002) p0.19) CONCLUSIONS: There are
significant changes in the newborns anthropometric measures
of mothers with higher BMI; therefore there could be an
association between maternal preconception overweight and
obesity with abnormal intrauterine growth.

Introduction: Infertility is a
disease characterized by the inability to achieve a
pregnancy after 12 months or more of unprotected sex. In
Mexico, assisted reproduction is on par with any country,
being the third nation in Latin America with the largest
number of reproduction centers. Objective: To determine the
demographic characteristics of mothers and children
undergoing assisted reproduction techniques (ART) at the
Hospital Español de México in 2016. Material and methods:
This is a descriptive, retrospective study that included
newborns product of ART performed in the Hospital Español
de México in 2016. Information was obtained on the method
of delivery, number of products, weeks of gestation at
birth, birth weight and height, and if they required
admission to the NICU, as well as the complications
presented. Results: 292 patients undergoing ART were
included. Of the associated maternal complications, the
most prevalent were infections during pregnancy. Data were
obtained from 373 newborns. The complications in these
patients are described, the most frequent being
respiratory. Conclusions: ART are increasingly used
treatments. Care must be taken when informing prospective
parents about associated complications, taking into account
the variability of the available data.
