Determinants of low birth weight in the children of adolescent mothers: a hierarchical analysis.

This study aimed to identify the determinants of low birth weight (LBW) amongst children of adolescent mothers through a hierarchical approach in a cross-sectional study of 751 adolescents attended at a public hospital in Rio de Janeiro. Sociodemographic data, prenatal care, and biological and maternal obstetric conditions were analyzed. Possible determinants of LBW were identified in the bivariate analysis and then hierarchical logistic regression models were tested, considering as taggered hierarchy of distal, intermediate, and proximal levels.

Association between maternal glucose levels during pregnancy and gestational diabetes mellitus: an analytical cross-sectional study.

Background: To evaluate the association between fasting glucose levels in women throughout pregnancy and the occurrence of gestational diabetes mellitus (GDM) and other pregnancy complications, macrosomia, and cesarean delivery.

Methods: An analytical cross-sectional study with 829 healthy pregnant women receiving health care at a public maternity unit in Rio de Janeiro between 1999 and 2008. The dependent variables assessed in the study were: GDM (was confirmed when two or more values were above the glucose curve using 100 g glucose), complications, mode of delivery and birth weight.

The performance of various anthropometric assessment methods for predicting low birth weight in adolescent pregnant women.

Objective: To evaluate the performance of various anthropometric evaluation methods for adolescent pregnant women in the prediction of birth weight.

Methods: It is a cross-sectional study including 826 adolescent pregnant women. In the pre-pregnancy body mass index (BMI) classification, the recommendations of the World Health Organization were compared with that of the Brazilian Ministry of Health and the Institute of Medicine (IOM) of 1992 and 2006.

Impact of an intervention nutrition program during prenatal on the weight of newborns from teenage mothers.

Introduction: The nutritional care for teenage mothers had been studied as a factor that influences the course of pregnancy and neonatal outcomes, especially in birth weight.

Objective: Evaluate the effect of a prenatal intervention nutrition program, with early start of the nutritional care and individualized attendance on teenage mother newborns' weight.

Methods: Not randomized study of intervention performed with 746 teenage mothers (14 to 19 years old), subdivided in historic control group (GI; n= 542) and intervention group (GII; n= 204).

[Nutritional care and weight gain in pregnant adolescents: a quantitative and qualitative approach].

This study sought to evaluate the impact of nutritional assistance (intervention) on total gestational weight gain in adolescents and to understand the perceptions of adolescents regarding the intervention. It is a quantitative and qualitative survey using triangulation methods conducted in a public maternity hospital in Rio de Janeiro with 204 adolescents, divided into pre-intervention and intervention groups. The hypothesis of homogeneity of proportions was tested by bivariate and multivariate analysis using Poisson regression with robust variance.

[Pre-pregnancy nutritional status, maternal weight gain, prenatal care, and adverse perinatal outcomes among adolescent mothers].

Objective: To identify the association between pre-gestational nutritional status, maternal weight gain, and prenatal care with low birth weight (LBW) and prematurity outcomes in infants of adolescent mothers.

Methods: Cross-sectional study with 542 pairs of adolescent mothers and their children attending a public maternity hospital in Rio de Janeiro. Data were collected from medical records.

[Interpersonal relations between health professional and pregnant adolescents: distances and approaches of integral and humanized care].

This study presents an analysis of relations between health professionals and pregnant adolescents in the installations of the prenatal care program of a public hospital in Rio de Janeiro. It involves qualitative research based on an interpretive approach, with comprehensiveness and humanization of care in relationship dimensions as a theoretical benchmark. Based on two predefined themes - the interaction between subjects and educational dimension of health practices - 22 individual and group care sessions were observed, with the participation of 31 pregnant adolescents, 5 professionals and 2 nutrition interns.

[Effect of weekly rice fortification with iron on anemia prevalence and hemoglobin concentration among children attending public daycare centers in Rio de Janeiro, Brazil].

This was a double-blind, placebo-controlled, community-based trial. For 16 weeks, children in the intervention group (n = 180) received iron-fortified rice, while children in the control group (n = 174) received rice with placebo. Anemia was defined as hemoglobin < 11.
