DESIGN: Cross-sectional study. SETTING: Multicentre investigation conducted in ten European cities.ParticipantsAdolescents aged 12.5-17.5 years (n 3215) who completed over 75 % of the NKT. RESULTS: Factor analysis indicated that the NKT can be analysed with a one-dimensional model. Eleven out of twenty-three items from the NKT presented adequate parameters and were selected to be included in the NKTS. Nutrition knowledge was positively associated with consumption of fruits, cereals, dairy products, pulses, meat and eggs, and fish, as well as with blood concentrations of vitamin C, beta-carotene, n-3 fatty acids, holo-transcobalamin, cobalamin and folate; nutrition knowledge was negatively associated with intake of olives and avocado, alcohol and savoury snacks. CONCLUSIONS: The NKTS assessed nutritional knowledge adequately and it is proposed as a new tool to investigate this subject in future studies.Lire moins >
