Abstract

In order to evaluate the repeatability of nutrient values estimated from a semiquantitative food frequency questionnaire(SFFQ) for elderly Korean, a sample of 100 participants(45 men, 55 women) were interviewed to complete a SFFQ developed by this study twice at an approximately 3 month interval. The mean age of subjects was 70.4 years. Males(mein=8.75 years) had more education thu females(1.4 years). In males, Nutrient values calculated from the repeat questionnaire were not significantly different from the baseline results by paired t test. Correlation coefficients of most nutrients ranged from 0.4-0.6. For most nutrients,60-73% males classified into the lowest tertile in baseline data belonged to the same tertile in a repeat questionnaire, but these values appeared to be less than 50% for females. These results were comparable to previously published results and confirm that repeatability of nutrient intakes estimated using SFFQs was acceptable. The repeatability of SFFQ was higher for males than females, which implies that years of schooling should be considered in the development of SFFQ for the elderly. Only f3r males, Mean Adequacy Ratio(MAR) of nutrient intake was higher for those who were less nutritionally at risk and less depressed, and physically functioned better. Considering the educational level of the Korean elderly overall, more studies on the development of simpler dietary assessment methods f3r this population are needed.(Korean J Nutrition 31(7) : 1183-1191, 1998)
