Objective: To assess ultra-processed food (UPF) consumption and its socio-demographic, psychosocial and behavioural correlates in a general population of Italian children, adolescents and adults.Design: Cross-sectional telephone-based surveySetting: Italy, 2010–2013.Participants: In total, 9078 participants (5–97 years) from the Italian Nutrition & Health Survey. Dietary intakes were collected by a 1-d 24-h dietary recall. UPF was defined by the NOVA classification and expressed as percentage of total energies.Results: Average energy intake from UPF (95 % CI) was 17·3 % (17·1 %, 17·6 %) among adults and 25·9 % (24·8 %, 27·0 %) in children/adolescents. Top sources of UPF were processed meats (32·5 %) and bread substitutes (16·7 %). Among adults, age (β= −3·10; 95 % CI (−4·40, −1·80) for >65 yearsv. 20–40 years;βs are dimensionless) and residing in Southern Italy (β= −0·73; 95 % CI (−1·32, −0·14)v. Northern) inversely associated with UPF. Screen view during meals was directly linked to UPF, as well as poor self-rated health (β= 5·32; 95 % CI (2·66, 7·99)), adverse life events (β= 2·33; 95 % CI (1·48, 3·18)) and low sleep quality (β= 2·34; 95 % CI (1·45, 3·23)). Boys consumed two-point percent more UPF of the total energy than girls (β= 2·01; 95 % CI (0·20, 3·82)). For all ages, a Mediterranean diet was inversely associated with UPF (β= −4·86; 95 % CI (−5·53, −4·20) for goodv. poor adherence in adults and (β= −5·08; 95 % CI (−8·38, −1·77) for kids).Conclusions: UPF contributes a modest proportion of energy to the diets of Italian adults while being one-quarter of the total energies in children/adolescents. UPF was associated with several psychosocial factors and eating behaviours. Increased adherence to Mediterranean diet would possibly result in lower UPF consumption.
To evaluate the adherence to Mediterranean diet (MD) and its major socioeconomic and psychosocial determinants in a large sample of the Italian population, covering three main geographical areas of the Country (Southern, Central and Northern). Data were obtained from the Italian Nutrition & Health Survey (INHES), including a total of 7, 430 participants (age >20) recruited from all over Italy (2010-13). Dietary information was collected by the European Food Propensity Questionnaire. Adherence to MD was assessed by using the MedDietScore based on 11 food groups. Associations were tested by multivariable logistic regression analysis (Odds ratio [OR] with 95% CI). Adherence to MD was higher in Southern Italy as compared with the Northern (OR = 1.34; 95% CI 1.18-1.53), and was closely associated with adult age (OR= 2.40; 1.61-3.58 for those aged > 75 years as compared with 20-34 years) and higher educational level (OR = 1.77; 1.40-2.24 for post-secondary education as opposed to lowest educational attainment). Subjects reporting adverse life events and those with family-related stress were less likely to show an optimal adherence to MD (OR = 0.55; 0.46-0.67 and OR = 0.44; 0.28-0.69, for highest vs. lowest tertile, respectively) as compared with adequate controls. A number of eating behaviours were also inversely associated with MD, such as consuming higher amount of alcohol in the weekend than in week days. Adherence to MD is strongly determined by age, geographical area and educational level. Psychosocial factors and several eating behaviours are also closely associated.
