Dietary patterns and food insecurity of students participating in a food aid programme: the Mediterranean perspective

Background: To explore the effect of household food insecurity on dietary patterns of children and adolescents participating in a school food-aid programme in regions of Greece with low socioeconomic status. Methods: A cross-sectional study was conducted during the school year 2013-14, among 406 schools in low socioeconomic status regions of Greece. Dietary habits and sociodemographic characteristics of students and their families were recorded. Factor analysis was used in order to derive children's and adolescents' dietary patterns and analysis of covariance was performed to examine the effect of households' food insecurity level on those patterns. A total of 31 399 students participated in the study; 16 652 children (5-11 years) and 14 747 adolescents (12-18 years). Results: Factor analysis identified five dietary patterns in both age groups, explaining the 49.1% (children) and 53.0% (adolescents) of the total variation in intake. After adjusting for various factors, the household's food insecurity was significantly associated with the majority of the derived patterns in both age groups, with most pronounced differences being observed for the consumption of red meat, poultry and fish, fruits, as well as red processed meat, cereals and dairy products, which was lower among children and adolescents with food insecurity. Children with food insecurity consumed significantly more unhealthy food, such as chips, fast food, sugared drinks, sweets, French fries and mayonnaise sauce. Conclusions: Promotion of healthy eating to households facing food insecurity is of crucial importance, giving emphasis in the design of low cost, yet highly nutritious programmes.
