SUMMARY:

Congenital Zika Syndrome (CZS) is one of the most well-known syndromes in Brazil, gaining greater prominence during the outbreak of infections that occurred in 2015. Zika virus is an arbovirus of the genus Flavivirus, family Flaviviridae, and its main vector is the mosquito Aedes aegypti. Microcephaly is one of the main neurological conditions resulting from Zika virus infection. Children with brain lesions or malformations of the central nervous system, such as microcephaly associated with CZS, may present feeding difficulties that directly impact nutritional status. Considering the importance of adequate nutrition for proper child development and improved quality of life for these children, the aim of this study was to investigate the presence of inadequate nutrient intake and the consumption of ultra-processed foods among children with microcephaly associated with CZS. This is a cross-sectional study including information on dietary intake and anthropometric data of children with microcephaly associated with CZS from the state of Rio Grande do Norte, Brazil. Recruitment was carried out at the Child and Adolescent Health Care Unit (UASCA) of the Onofre Lopes University Hospital (HUOL). Up to three 24-hour dietary recalls were collected to analyze information on foods consumed by the children on the day prior to the consultations. Nutrient intake analysis was based on data from the Brazilian Food Composition Table (TBCA), and the prevalence of micronutrient inadequacy was calculated according to sex, age, and the Estimated Average Requirement (EAR). Food classification according to the degree of processing was performed using the NOVA classification system to identify ultra-processed foods (UPFs). High prevalences of micronutrient inadequacy were observed, particularly for magnesium (93.32%), vitamin E (73.24%), and selenium (71.23%). In addition, children consumed an average of 21.25% of their total energy intake from UPFs. When energy intake from UPFs was analyzed according to nutritional status classification, children classified as having high weight-for-age according to WHO criteria presented the highest percentage of calories derived from UPFs (p = 0.004). In conclusion, children with microcephaly associated with CZS present a high prevalence of inadequate micronutrient intake, anthropometric alterations such as low weight-for-age and short stature-for-age, as well as excessive consumption of UPFs.
