Objective: To validate a diet history questionnaire (DHQ) using a weighed food record (WFR) as the standard method in the estimation of food consumption and nutrient intake in a group of adults. Design: WFR: all foods consumed by subjects during 7 consecutive days were weighed and recorded by nutrition students. Two DHQ interviews were carried out on days 1 (first diet history questionnaire, DHQ1) and 28 (second diet history questionnaire, DHQ2). Setting: Costa Rica. Subjects: Sixty adults: 30 men and 30 women; 30 living in urban and 30 in rural areas. Results: In comparison to the WFR, the DHQ1 gave statistically significant higher estimates of the mean intake of 19 nutrients for men and of three nutrients for women. The uncorrected correlation coefficients for nutrient intake according to both methods ranged from 0.40 to 0.83 for males and from 0.22 to 0.62 for females. Percentage of subjects classified in the same quartiles of nutrient intake according to each method ranged from 33.3% to 63.3% for males and from 23.3% to 53.3% for females. Misclassification in extreme quartiles ranged from 0% to 13.3% for both sexes. The mean food group consumption, according to the DHQ1, when compared with the WFR, gave statistically significant differences for three of the 18 food groups for men and for two groups in the case of women. The two applications of the DHQ gave similar results. Conclusion: Validation of a DHQ using a WFR as the standard method gave results that compare favourably with those reported by other authors. This study found important differences in the response of men and women to the DHQ: among men, the estimates of mean nutrient intake from DHQ1 were significantly greater than those of the WFR, while in the case of women, the mean nutrient intake estimates from both methods were not significantly different. There was a higher degree of correlation between the DHQ1 and the WFR mean nutrient intakes among men than among women. The DHQ showed good reproducibility. Keywords Diet History Questionnaire Dietary assessment methods Nutritional epidemiologyThe health and nutrition situation of the Costa Rican population is one of transition. The health indicators show a reduction in the incidence of childhood infectious diseases and an increase in chronic diseases among adults 1 , a transformation that is associated, among other things, with changing lifestyle patterns and, more specifically, changes in diet. A few studies have been carried out in Costa Rica on the relationship between diet and chronic diseases. Data have been published on the prevalence of cardiovascular risk factors 2 , cervical cancer 3-5 and gastric cancer 6-10 , which is of special interest as Costa Rica has one of the highest incidence and death rates for this type of cancer in the world 11 .The study of diet in epidemiological research requires methods that measure food consumption over the longer rather than shorter term, which can be applied to groups with different characteristics and not just those who are highly motivated an...

“…Interview-based methods such as the diet history questionnaire (DHQ) and food frequency questionnaire (FFQ) are likely candidates. The latter has been applied in several studies of diet and health and recently in Costa Rica 12 . However, use of the FFQ has been questioned by some researchers due to insufficient precision [13][14][15] .…”

Evaluation of the odd fatty acids 15:0 and 17:0 in serum and adipose tissue as markers of intake of milk and dairy fat

Background: There is a need for biomarkers of dietary saturated fatty acids, because several diseases have been related to intake of these fatty acids. Objective: To examine the relation between intake of dairy fat and the proportion of pentadecanoic (15:0) and heptadecanoic (17:0) acid in serum and adipose tissue. Design: Healthy men aged 21-55 y provided serum (n ¼ 110) and adipose tissue samples (n ¼ 107) and completed both 14 days weighed records (WR) and a 180-item food frequency questionnaire (FFQ). The proportions of 15:0 and 17:0 acid in serum and adipose tissue as measured by gas liquid chromatography were evaluated as biomarkers for fat intake from dairy products using Pearsons correlation coefficient and the method of triads. Results: The strongest correlation coefficients were observed between total intake of dairy fat estimated from WR and relative content of 15:0 in adipose tissue (0.52, 95% CI: 0.37, 0.65) and total serum (0.43, 95% CI 0.26, 0.57). A consistent inverse association was observed between the intake of milk fat and relative serum content of 17:0. The validity coefficients observed for the intake of dairy fat estimated from weighed records, the 180-item FFQ and by the relative content of 15:0 in serum and adipose tissue were 0.94 (95% CI: 0.68, 1.00), 0.50 (95% CI: 0.29, 0.67), 0.49 (95% CI: 0.32, 0.67) and 0.56 (95% CI: 0.28, 0.82), respectively. Conclusion: Relative content of 15:0 in serum and adipose tissue may be a useful biomarker for the intake of total dairy fat, whereas FFQs and WRs may provide better estimates of the intake of fat from milk.
