This study investigated food insecurity in households with young children in the Western Brazilian Amazon, finding a high prevalence associated with low income and parental education.

This population-based household survey studied the prevalence of food insecurity and its associated factors among 557 children under five and their families living in an urban cluster in a municipality in the Western Brazilian Amazon, using the Brazilian Food Insecurity Scale and multiple Poisson regression to estimate prevalence ratios. The study found a high prevalence of food insecurity (76.47%), with associations with low family income, participation in governmental income transfer programs, and household heads having less than seven years of schooling, and it also reported substantial frequencies of height deficit and overweight among children. The authors’ interpretation links these patterns to geographic isolation and social exclusion, and the caveat is that the work is a preprint and tables were only available as downloadable files, indicating limited peer-reviewed context. Relevance to endometriosis: the paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Abstract Background: Hunger affects millions of people worldwide. In the current pandemic scenario of COVID-19, Brazil experienced an epidemic peak of hunger, amplifying existing pre-pandemic vulnerabilities, mainly in the Northern Region of the Country. The aim of the present study was to investigate the prevalence of food insecurity and its associated factors in homes with children under five years of age in an urban cluster of a municipality of the Western Brazilian Amazon. Methods: A household survey was conducted with a probabilistic sample of 557 children and their families. Food insecurity (FI) was determined using the Brazilian Food Insecurity Scale. Associations between variables were analyzed based on the prevalence ratio (PR) and respective 95% confidence intervals (CI) calculated through multiple Poisson regression analysis. Variables with a p -value <0.05 after adjustments were considered significantly associated with the outcome. Results: A high prevalence of food insecurity was found among the families in the study (76.47%, PR=1.90, CI: 1.36-2.67, p <0.001); 42.90% had moderate (PR=1.93, CI: 1.31-2.83, p <0.01) and severe FI (PR=1.41, CI: 1.10-1.83, p <0.02), which was associated with low family income, participation in governmental income transfer programs, and heads of households with less than seven years of schooling. Moreover, substantial frequencies of height deficit and overweight were found among the children. Conclusions: The high prevalence of hunger and food insecurity and its associated factors reflects the context of geographic isolation and social exclusion in which these families live, suggesting that a substantial portion of the population under five years of age had experienced episodes of hunger in the 90 days prior to the survey. The high prevalence of height deficit and overweight among the children reveals a scenario of epidemiological/nutritional polarization, requiring the formulation of specific public policies for this population.
