Diet quality index DQI) offers a new way of comparing eating habits across populations and across countries. Nutrients and food consumption data from 100 elderly Korean women aged 65 and older were collected in Seoul or Kyunggi-do, Korea by the 24 hour recall method. Diet quality index (DQI) was computed for 1049 elderly women (65 and older) from the 1994-1996 Continuing Survey of Food Intakes by Individuals (CSFII) in the US according to US dietary guidelines, and applied to the diet of elderly Korean women for purposes of comparison. A modified 16-point DQI awarded 2 points each for moderate consumption of fat (≤ 30% energy), saturated fat (≤ 10%), cholesterol (≤ 300 mg/day), sodium (≤ 2400 mg/day), and protein (≤ 100% RDA), adequate intakes of carbohydrate (50% energy) and calcium ( 100% RDA), and plenty of fruits and vegetables ( 5 servings). Criteria were based on US dietary guidelines. Partial scores were given if subjects were close to meeting these cutoff points. Diets with ≤ 300 mg cholesterol/day were reported by 97% or the Korean sample and 82% of the American sample, while 90% of the Koreans and 42% of the Americans met the goal of ≤ 30% of energy from fat, and 98% of the Koreans and 47% of American met the recommendation of ≤ 10% of energy from saturated fat. In contrast, only 8% of the Korean sample met the sodium recommendation of ≤ 2400 mg sodium per day, whereas 54% of the American subjects met this goal. The mean DQI scores were 10.1 for the elderly American women and 11.3 for the elderly Korean women. Overall, the elderly Korean diet was more consistent with the US dietary guidelines than the elderly American diet.
