The Malmö food study : The reproducibility of a novel diet history method and an extensive food frequency questionnaire
(1996) In European Journal of Clinical Nutrition 50(3). p.134-142- Abstract
Objective: To assess the reproducibility of two diet assessment methods, an extensive quantitative food frequency questionnaire (method A) and a novel shorter quantitative food frequency questionnaire with a 14 day food record (method B). Design: A randomized prospective cohort study. Setting: General community. Subjects: 241 residents of the town of Malmö, aged between 50-69 years, 126 men and 115 women who completed the methods one year apart. Methods: Both diet methods were designed to cover the whole diet and portion sizes were estimated using a booklet with 120 photographs; method A comprised 250 items and method B combined a two-week food record measuring lunch and dinner meals and a shorter 130 item quantitative food frequency...

Objective: To assess the reproducibility of two diet assessment methods, an extensive quantitative food frequency questionnaire (method A) and a novel shorter quantitative food frequency questionnaire with a 14 day food record (method B). Design: A randomized prospective cohort study. Setting: General community. Subjects: 241 residents of the town of Malmö, aged between 50-69 years, 126 men and 115 women who completed the methods one year apart. Methods: Both diet methods were designed to cover the whole diet and portion sizes were estimated using a booklet with 120 photographs; method A comprised 250 items and method B combined a two-week food record measuring lunch and dinner meals and a shorter 130 item quantitative food frequency questionnaire for average consumption of foods, snacks and beverages during the past year; Results: The percent difference between estimated energy intake one year apart were for men 10.7% for method A and 0.2% for method B, corresponding values for women 13.7% and 1.1%. Method B showed a good agreement between measurements for energy-providing nutrients, micronutrients and major food groups, i.e. meat products, edible fats, milk, fish, fruits and vegetables with correlation coefficients between 0.70-0.90 for women. The percent difference of average intake of edible fat was about 10%. Average energy-adjusted Pearson's correlation coefficients were of the order of 0.50-0.80 for most nutrients including 14 fatty acids. The correlation for the ratio between polyunsaturated and saturated fatty acids were about 0.70 for men and 0.80 for women; Conclusion: A modified diet history method combining a food record and a food frequency questionnaire shows good reproducibiiity. Sponsorship: This study was granted by the Swedish Medical research Council (Grant K 84-19X-7010-1) and by the International Agency for Research on cancer (Collaborative research agreement DEB/85/43).
