[Nutritional balance of the diet of the adult residents of Geneva].

Diet of the Swiss population has probably changed over the last 10 years, but these changes have not been recorded yet by nutritional studies. In the present study, 3 registered dieticians interviewed over the telephone 626 adults, resident of Canton Geneva, using a 24 hour recall. Interviews were performed during the 7 days of the week. Participants were randomly selected according to their age, sex and nationality. Participation was 80%. The following caloric (C) and nutritional intakes in proteins (P), lipids (L), carbohydrates (CH) and alcohol (A) were recorded: In non Swiss men: C = 2464 kcal/j., P = 16.2%, L = 32.4%, CH = 44.4%, A = 7.0%; in Swiss men: C = 2752 kcal/j., P = 15.3%, L = 34.0%, CH = 43.5%, A = 7.1%; in non Swiss women: C = 1897 kcal/j., P = 16.4%, L = 35.1%, CH = 46.5%, A = 2.4%; in Swiss women: C = 1865 kcal/j., P = 15.0%, L = 35.3%, CH = 46.0%, A = 3.2%. Total caloric intake and iron intake decreased with age. Older women ate less calcium than younger. In summary, the most important determinants of diet are age and sex. Proportion of lipids is relatively low in both men and women. Small differences related to nationality were observed in men.
