The aim of the study was to compare nutrient intakes estimated by a self-administered food frequency questionnaire and a 10-day weighed record in 122 men and 179 women cigarette smokers aged 40-59 years.
Comparison of nutrient intake by means, per cent mean differences and ability to rank individuals correctly between the methods showed good agreement for most nutrients.
Spearman rank correlations were statistically significant for all nutrients except vitamin A intake in men; adjusting for energy intake increased the strength of the associations found.
Bland-Altman plots showed differences in agreement over the range of intakes for energy in men and ascorbic acid in women.
