The trajectory of head circumference and neurodevelopment in very preterm newborns during the first two years of life: a cohort study.

Objective: To evaluate the growth trajectory of head circumference and neurodevelopment, and to correlate head circumference with cognitive, language, and motor outcomes during the first two years.

Method: Prospective cohort study in a tertiary hospital including 95 newborns under 32 weeks or 1500 g. Neonates who developed major neonatal morbidities were excluded.

Association between preterm infant body composition in the first 3 months of life and preschool age: a cohort study.

Compared with full-term infants, preterm infants have fat-free mass deficit in the first months of life, which increases the risk of metabolic diseases in the future. In this cohort of children born under 32-week gestational age or less than 1500 g, we aimed to evaluate the associations of body composition at term equivalent age and in the first 3 months of life with fat-free mass and fat mass percentage at 4 to 7 years of life. Body composition assessments by air displacement plethysmography and anthropometry were performed at term, at 3 months of corrected age, and at 4 to 7 years of age.

Physical and social activities constraint and its effects on Body Mass Index of former Neonatal Intensive Care children.

Objective: It is reported weight gain in children due to the confinement measures during the Covid-19 pandemic. We aimed to describe the effect of these measures on the nutritional status of former Neonatal Intensive Care Unit children.

Methods: Cross-sectional study, including former Neonatal Intensive Care Unit children.

Body composition at 4 to 7 years of age in children born <32 weeks gestational age or 1500 g: A cohort study.

Background: Small for gestational age preterm infants show differences in body composition when compared to those appropriate for gestational age at term, which have consequences on metabolism.

Aim: To compare growth and body composition of children born small and appropriate for gestational age between 4 and 7 years.

Method: A Cohort of small and appropriate for gestational age infants <32 weeks or 1500 g were followed at term and 3 months corrected ages and at 4 to 7 years.

Influence of gestational and perinatal factors on body composition of full-term newborns.

Objective: To evaluate the influence of gestational and perinatal factors on body composition and birth weight of full-term newborns.

Method: This was a cross-sectional study, within a prospective cohort, consisting of 124 postpartum women and their newborns. Data included the following: maternal age; ethnicity; pre-gestational body mass index; gestational weight gain; parity; gestational morbidities (hypertension and gestational diabetes mellitus); gestational age at birth; birth weight; and newborn's gender.

Growth and body composition of preterm infants less than or equal to 32 weeks: Cohort study.

Background: Extremely preterm infants with weights less than the 10th percentile at discharge have a fat-free mass deficit.

Aim: To analyze the relationship of weight Z-scores less than -2SD at term age with fat-free mass and fat mass at term age and at 1 and 3 months of corrected age in very preterm infants.

Study Design: COHORT STUDY: Subjects: Sixty-six preterm infants born before or at 32 weeks gestation with birth weight equal or greater than the 10th percentile for age were included at term age.
