RESUMEN
Household food insecurity (HFI) has been related to adverse maternal-child health outcomes and mental health worsening during pregnancy. Few studies evaluated the temporal association between HFI and anxiety and depressive symptoms in pregnant women, and this association remains not completely understood. This study aimed to systematically review the association between HFI and symptoms of depression and anxiety in pregnant individuals. The systematic review protocol was registered in the International Prospective Register of Systematic Reviews (CRD42022373615). Systematic searches were conducted on 10 electronic databases and grey literature. Two researchers independently conducted the study selection, data extraction process, and the risk of bias assessment. Random-effects meta-analysis models were used, and I2 > 40% indicated high heterogeneity across studies. Eighteen articles were included for the systematic review, comprising n = 27,882, and a total of 18,987 pregnant individuals aged between 14 and 45 years were included in the meta-analysis. The prevalence of HFI reported in studies ranged from 12.6% to 62.1% (n = 17). The prevalence of depressive and anxiety symptoms ranged from 18% to 49% (n = 11) and 23% to 34% (n = 2), respectively. HFI during pregnancy was associated with increased odds of experiencing symptoms of depression [(OR: 2.52; 95% CI: 2.11-3.02), I2 = 73.23%]. The quality of evidence was very low due to high heterogeneity. Our findings highlighted the association between HFI and depression symptoms during pregnancy. Findings from this study suggest the importance of assessing HFI and mental health during pregnancy.
RESUMEN
Combined deficiencies of nutrients such as iron and folic acid intake during pregnancy are related to nutritional deficiencies risk, such as anemia. The objective of this study was to analyze the association between risk factors (sociodemographic, dietary and lifestyle) and the intake of iron and folate by pregnant women followed up in Primary Health Care (PHC) in the Federal District, Brazil. A cross-sectional observational study was carried out with adult pregnant women of different gestational ages. A semi-structured questionnaire was applied by researchers trained to collect sociodemographic, economic, environmental, and health data. Two nonconsecutive 24-hour recalls (24hr) were carried out to collect data about food consumption. Multivariate linear regression models were used to analyze the association between sociodemographic and dietary risk factors and the consumption of iron and folate. The mean daily energy intake was 1726 kcal (95% CI 1641-1811), with 22.4% (95% CI 20.09-24.66) derived from ultra-processed foods (UPFs). The mean iron and folate intake were 5.28 mg (95% CI 5.09-5.48) and 193.42 µg (95% CI 182.22-204.61), respectively. According to the multivariate model, the highest quintile of ultra-processed foods intake was associated with lower iron (ß = -1.15; IC 95%: -1.74; 0.55; p < 0.001) and folate intake (ß = -63.23; IC 95%: -98.32; -28.15; p < 0.001). Pregnant women with high school degree presented higher iron intake (ß = 0.74; IC 95%: 0.20; 1.28; p = 0.007) and folate intake (ß = 38.95; IC 95%: 6.96; 70.95; p = 0.017) compared to pregnant women with elementary school degree. Folate consumption was also associated with the second gestational period (ß = 39.44; IC 95%: 5.58; 73.30; p = 0.023) and pregnancy planning (ß = 26.88; IC 95%: 3.58; 50.18; p = 0.024). Further research is warranted to enhance evidence on the relationship between the role of processed foods and micronutrients intake to strengthen the nutritional quality of diet of pregnant women attended in Primary Health Care.

Despite the global tendency of maternal anaemia to decline, the persistence of anaemia in Brazil is an important health problem given its vulnerability to deficiencies and the significant increase in nutritional requirements during pregnancy. The aim of this study was to estimate the prevalence of anaemia in Brazilian pregnant women through a systematic literature review and meta-analysis. The systematic review was carried out according to Systematic Reviews and Meta-Analyses PRISMA checklist recommendations and using the following electronic databases: Medline, Scopus, Embase, Web of Science, Lilacs, Scielo, Google Scholar, and CAPES Catalog of Theses and Dissertations. Studies that presented a prevalence of anaemia data in Brazilian pregnant women, considering all gestational trimesters, were included. The total sample included 12,792 pregnant women covering all gestational trimesters. The pooled prevalence of anaemia in Brazilian pregnant women was 23% (95% CI: 20-27), with the highest prevalence in the Northeast Region at 26% (95% CI 23-29), while the lowest prevalence was observed in the North Region with 17% (95% CI 14-20). Among the subgroups, no statistical difference was observed. The prevalence of anaemia status in Brazil is still classified as a moderate public health problem according to the World Health Organization maternal anaemia classification.
