This study was conducted to develop a computerized food frequency questionnaire (FFQ) for assessing nutritional
status of women of child-bearing age. Computerized food frequency questionnaire (FFQ) that reflect intakes of energy,
carbohydrate, fat and protein was developed for women of child-bearing age. This FFQ is composed of 61 foods or
food groups containing 192 dish items. To estimate of energy intake easily, we have developed a computer program
that can be viewed on a computer screen in an actual size of dish items. Nutrient intakes of the last three months by
the FFQ was validated with comparing the result of a 3-day diet record through 92 college students aged from 20 to
30. The level of energy, carbohydrate and sodium of estimating by the FFQ method was significantly higher than the
level of a 3-day diet records method (p < 0.01). Pearson’s correlation coefficients between the two methods were 0.50
for carbohydrate (p < 0.01), 0.55 for energy (p < 0.01) and 0.56 for protein (p < 0.01). Spearman’s correlation
coefficients were 0.53 for carbohydrate (p < 0.01), 0.55 for energy (p < 0.01) and 0.52 for protein (p < 0.01). The
percent of subject in the lowest quartile in a 3-day diet record belonged to the first and second lowest quartile in food
frequency questionnaire is 78.2% in energy, 91.3% in carbohydrate, 78.2% in protein, 69.5% in fat. Also, the percent
of subject in the highest quartile in a 3-day diet record belong to the first and second highest quartile in food
frequency questionnaire is 78.3% in energy, 73.9% in carbohydrate, 82.6% in protein, and 73.9% in fat. On the whole,
the result of this study seemed to be in good agreement with other studies. Therefore, the FFQ developed by this
study is considered to be a reliable tool to assess nutrients and food intakes for women of child-bearing age. (Korean
