Household food insecurity and socio-demographic determinants in young adults: findings from a Portuguese population-based sample.

objectivesThis study evaluated the prevalence and the socio-demographic determinants of food insecurity among young adults at a time of economic crisis recovery.

methodsA cross-sectional study including 954 young adults (26 years old) from the EPITeen cohort (Porto, Portugal) was conducted. Food security status was evaluated using the US Household Food Security Survey Module: Six-Item Short Form. Associations between socio-demographic characteristics (sex, education, occupation, household size and structure and household income perception) and food insecurity were estimated using logistic regression.

resultsAt a time of economic crisis recovery, 11.0% of young adults experienced food insecurity. A higher odds of belonging to a food insecure household was observed in participants reporting an insufficient household income (OR = 23.3; 95% CI 11.3-47.8), those with less education (OR = 1.7; 95% CI 1.0-2.8), lower white-collar workers (OR = 2.3; 95% CI 1.2-4.2) and those living within a nuclear family including a partner and/or children (OR = 2.0; 95% CI 1.1-3.7).

conclusionsOur findings support the need for interventions targeting those from lower income, from nuclear families of young adults with a partner and/or descendants, less educated and with non-manual unskilled occupations, to reduce food insecurity, particularly in economic vulnerable settings.
