This ecological study aimed to analyze the trend of the nutritional status of pregnant adolescent beneficiaries of the Brazilian Bolsa Família conditional cash transfer program in the 2008-2018 period. We evaluated secondary data of pregnant adolescent beneficiaries of the Bolsa Família Program from January 2008 to December 2018, extracted from the public reports of the WEB Food and Nutrition Surveillance System. We accessed the monitoring reports on the consolidated public-access health conditionalities of the Bolsa Família Program, always considering the second validity. An annual variation of -1.2% (95%CI: [-1.6; -0.8] p<0.01) was observed in the prevalence of underweight in Brazil in the studied sample. The prevalence of overweight and obesity in the country had annual variations of 2.9% (95%CI: [2.0; 3.7] p<0.01) and 7.5% (95%CI: [5.7; 9.3] p<0.01), respectively. We conclude by saying, that, in the evaluated period, the prevalence of underweight among pregnant adolescent beneficiaries of the Bolsa Família Program showed a decreasing trend, while the prevalence of overweight and obesity increased throughout Brazil.

The clinical and nutritional status of pregnant women are important variables for birth-weight risk inadequacies. Thus, this study sought to evaluate the nutritional status of high-risk pregnant women and its association with birth weight of their offspring. It involved a cross-sectional study with high-risk pregnant women assisted at the university hospital of Maceio in the State of Alagoas and their newborns. The nutritional status of pregnant women and their offspring was evaluated according to body mass index for gestational age and birth weight, respectively. The association between maternal factors (comorbidities and nutritional status) and birth weight was assessed by the chi-square test and Pearson correlation, by adopting a confidence level of 95%. One hundred and forty-nine pregnant women were studied, 19.7% of whom were of normal weight; 32% were underweight; and 48.3% were overweight. Among newborns, 39.6% referred to as small for gestational age (SGA); 26.8% appropriate for gestational age (AGA) and 33.6% large for gestational age (LGA). LGA offspring were associated with overweight and the presence of metabolic comorbidities and SGA offspring were associated with insufficient gestational weight gain, whereby interventions are needed to reduce these outcomes.
