, , , , , , , , To estimate the prevalence of inadequate vitamin D level and its associated factors for women of childbearing age in Brazil.
A systematic reviewwas conducted (last updatedMay 2020).Meta-analyses were performed using the inverse-variance for fixed models with summary proportion calculation by Freeman-Tukey double arcsine. Reporting and methodological quality were assessed using the Joanna Briggs Institute tool for prevalence studies.
Our review identified 31 studies, comprising 4,006 participants. All the studies had at least one weakness, mainly due to the use of convenience sampling and small sample size. The overall prevalence of vitamin D deficiency, insufficiency, and both deficiency and insufficiency were 35% (confidence interval, 95%CI: 34-37%), 42% (95%CI: 41-44%), and 72% (95%CI: 71-74%), respectively.
Although the magnitude of the prevalence of inadequate levels of vitamin D is uncertain, the evidence suggests that presence of vitamin D deficiency or insufficiency in women of reproductive age can cause moderate to severe problems.

, , , To analyze the consumption of minimally-processed and ultraprocessed foods in relation with sociodemographic variables, maternal habits, educational activity received during prenatal care and clinical history.
A cross-sectional, analytical and descriptive study with 1,035 pregnant women who lives in the municipalities of the metropolitan region of Grande Vitória, Espírito Santo, Brazil (RMGV-ES), and who were hospitalized in establishments of the Unified Health System (SUS) due to childbirth (April-September 2010). The food frequency questionnaire, pregnant woman’s card and information from the medical records of the health facility unit were analyzed. The Chi-square test and the binary logistic regression model were used to investigate the association between the independent variables and the consumption of ultraprocessed foods.
It was identified that pregnant women ≤ 19 years of agewere 2.9 timesmore likely to consume ultraprocessed foods (confidence interval [CI] 95% 1.683-5.168, p< 0.001), while those ≥ 35 years old were less likely to consume them (odds ratio [OR] 0.265, 95% CI 0.105-0.666, p= 0.005). Maternal smoking increased the odds of consumption of ultraprocessed foods by 2.2 times (95% CI 1.202-4.199, p= 0.011) and pregnant womenwho did not obtain information on healthy food during prenatal care presented 54.1% less chances of consuming minimally-processed foods (OR 0.459, 95% CI 0.307-0.687, p< 0.001).
Smoking during the gestational period and being a teenager are factors that influence the consumption of ultraprocessed foods of pregnant women. Race/ color, head of household, age group, receiving of information about feeding in the prenatal period and not having smoked in gestation determined the consumption of minimally-processed foods.

PURPOSE: to evaluate changes in the nutritional status of lactating adolescents in different postpartum weeks. METHOD: this is an analytical, observational, longitudinal study. Lactating adolescents were followed-up from the 5th to the 15th postpartum week (PPW). The nutritional status was evaluated in the 5th, 10th and 15th PPW by the Body Mass Index (BMI/age). A colorimetric method was used to determine hemoglobin level and microcentrifugation to define hematocrit. ANOVA with repeated measures was used to compare means, followed by the Tukey post-test. The level of significance was 5%. RESULTS: modification in nutritional status was observed from the pregestational period to the 15th PPW, with a reduction in the frequency of lactating adolescents with low weight (from 21% to 9%) and a rise in the frequency of overweight (21% to 27%) and eutrophic (58% to 64%) adolescents. Although mean hemoglobin (12.3±1.7 g/dL) and hematocrit (39.0±4.0%) levels were normal, a high frequency of anemia (30%) was observed throughout the study period. CONCLUSION: the present results show that the body weight of lactating adolescents rises during the lactation period and could lead to a higher frequency of obesity among adolescents. Anemia is still a nutritional problem, not only during pregnancy, but also during the postpartum period. It is necessary to prevent and treat probable subclinical nutritional deficiencies at this biological time.
