Abstract
In 2020, nearly one-in-three people globally lacked access to adequate food; that is, they were food insecure. Food insecurity (FI) has four dimensions – availability, access, utilization, and stability – and is linked to poor health outcomes. Our understanding of the relationship between FI and health, however, is compromised by the fact that most research on FI focuses on the access dimension. This has resulted in a poor understanding of the utilization dimension; that is, how people cope with inadequate access to food as manifest by food choice. Here, we explore the relationship between maternal perceptions of food access and food choice, measured as dietary diversity, in 706 Nicaraguan households across urban, peri-urban and rural settings, and hypothesize that as food access worsens, dietary diversity will decline. Access was measured using the Latin American and Caribbean Food Security Scale. Dietary data were collected via a locally-developed, 7-day food-frequency questionnaire and converted to a household dietary diversity score (HDDS). The relationship was analyzed via multiple regression and ANOVA. We found that 82% of households experienced insufficient access to food and had a mean HDDS=10.9±1.2 out of a maximum score of 12. As access to food worsened, dietary diversity declined (r2=0.15, p<0.001), and the effect of food access on HDDS varied across settings (F=3.53, p=0.02). While we found a relationship between food access and HDDS, the high prevalence of insufficient access to food combined with a high average HDDS suggests that HDDS is too blunt an instrument to capture the lived experience.
