FELIX GUTIERREZ, Andrea et al. The COVID-19 pandemic and its impact on the nutrition of women and children in marginalized areas of Hermosillo. Biotecnia [online]. 2024, vol.26, e2435.  Epub 21-Abr-2025. ISSN 1665-1456.  https://doi.org/10.18633/biotecnia.v26.2435.

The COVID-19 pandemic had significant repercussions on the nutritional health of the population in Hermosillo, Mexico. This study analyzed the consequences of the food environment and nutritional food insecurity in Hermosillo households with medium and high levels of marginalization. In 2021, 104 women and 41 children participated in this study, with data contrasted with information from 2019. Changes in the purchasing patterns of women were identified (p = 0.001), showing a preference for convenience stores, linked to a larger waist circumference (p = 0.001). Among children, there was a 6.5 % increase in the prevalence of overweight and obesity according to BMI-for-age Z score, and it was negatively associated with grocery shopping at convenience stores (p = 0.02). Additionally, an increase in the mean BMI of women was observed, rising from 29.6 to 30.5 (p = 0.05). There was also a 9 % rise in moderate nutritional food insecurity cases after the pandemic. A correlation was found between food acquisition locations and the nutritional status of women and children during the pandemic.
