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

This study evaluated the prevalence and the socio-demographic determinants of food insecurity among young adults at a time of economic crisis recovery.
A 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.
At 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).
Our 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.
