The purpose of this study was to compare the nutrient intake and diet quality of male college student according to smoking groups. Subjects were recruited and divided into three groups according to the smoking, which included non-smoker (n = 100), light-smoker (n = 78; packyear < 5), and heavy-smoker (n = 76; packyear > or = 5). Subjects were interviewed using a general questionnaire, 24-hour recall method for dietary intake and diet quality. The average age of the subjects were 22.7 years for non-smoker, 23.5 years for light-smoker, and 23.4 years for heavy-smoker. Also the results showed that the heavy-smoker was significantly more often to drink coffe and alcohol compared with the other two groups (p < 0.001, p < 0.05). The mean daily energy intake was 2278.1 kcal in non-smoker, 2148.3 kcal in light-smoker, and 2144.4 kcal in heavy-smoker. The heavy-smoker consumed significantly lower intakes of vitamin C (p < 0.001), calcium (p < 0.01), animal calcium (p < 0.01), and potassium (p < 0.05) compared to the non-smoker and light-smoker. Also NAR (Nutrient Adequacy Ratio), ND (Nutrient Density), and INQ (Index of Nutritional Quality) of these nutrients in heavy-smoker were lower than the other two groups. Mean adequacy ratio (MAR) was 0.78 in non-smoker, 0.78 in light-smoker, and 0.74 in heavy smoker (p < 0.05). The heavy-smoker consumed significantly lower intakes of fruits (p < 0.001) compared to the non-smoker and light-smoker. The DVS (Dietary Variety Score) of heavy-smoker (26.8) was significantly lower than that 30.4 of non-smoker and 31.5 of light-smoker (p < 0.01). In conclusion, heavy-smoker man have low intake status of vitamin C, calcium and potassium, and partly low diet quality. Therefore it was needed that well planed diet to replace the nutrients supplied from excluded food groups in heavy- smoker.
