Abstract: International audience ; Background Comparable international data on food and nutrient intake is often hindered by the lack of a common instrument to assess food intake. Objective Within the Global Allergy and Asthma European Network of Excellence (GA2LEN) we developed and piloted a food frequency questionnaire (FFQ) to assess its validity in Europe. Design Five countries participating in GA2LEN took part in the pilot. 200 adults aged 31 to 75 years old were invited to answer a FFQ in 2 occasions and to give a blood sample. The intra-class correlation coefficient (ICC) was used to assess repeatability of the FFQ. Plasma phospholipid fatty acids were analysed by gas chromatography. Pearson correlation was used to analyse the correlation between estimated dietary fatty acid intake and plasma phospholipid fatty acid levels. Results 177 participants (89%) had complete data on FFQ1 and plasma phospholipid fatty acids. 152 participants (76%) completed both FFQs. ICCs between macronutrients ranged from 0.70 (saturated fatty acids) to 0.78 (proteins) and between 0.70 (retinol) to 0.81 (vitamin D) for micronutrients. Dietary n-3 fatty acids showed a good correlation with total plasma phospholipid n-3 fatty acids and with docosahexaenoic acid in the whole sample (0.40) and in individual countries. Poor correlations were observed for other fatty acids. Conclusion The GA2LEN FFQ is an appropriate tool to estimate dietary intake for a range of nutrients across Europe regardless of cultural and linguistic differences. The FFQ seems to be useful to estimate the intake of n-3 fatty acids but not other fatty acids.
