There is overwhelming evidence that links diet with chronic disease risk factors, but accurate assessments of dietary intakes are essential for determination of the association between diet and chronic diseases. Data from the Third National Health and Nutrition Examination Survey were used to compare the prevalence of chronic disease risk factors (anthropometric measurements: body mass index (BMI) and waist circumference; physiological measurements: blood pressure; and biochemical variables: serum LDL, HDL, total-cholesterol and triglycerides), based on three categories of dietary reporting. Males, 19-90 years old, were asked to categorize their reported dietary intakes as “less than usual” (Group 1), “usual” (Group 2) or “more than usual” (Group 3). The sample consisted of 1,328 participants of which 2%, 84% and 14% represented Groups 1, 2 and 3, respectively. Weighted data were analyzed using SAS and SUDAAN. Results showed that 19% and 48% of study participants were classified as overweight or obese based on waist circumference and body mass index measurements, respectively. Group 1 participants had a greater prevalence of overweight or obesity than the other groups. Also, Group 1 participants had 3 and 6 times greater prevalence of hypertension than groups 2 and 3 participants, respectively. Further analyses showed a significant difference in blood pressure, BMI , LDL- and HDL- serum cholesterol levels based on the 3 categories of reported dietary intakes. It is suggested that utilizing these categories in dietary data analyses would enhance validity and reliability of reported dietary information and may provide valuable insights in diet-related chronic disease assessments.
