The Effects of Vit C Supplementation and Nutrition Education on Nutrition Knowledge, Food Habits and Antioxidative Enzyme Activity in Male Adolescent Smokers: Jae Yeon Lim, Jung Hee Kim; Korean J Community Nutr 2001;6(3):282-289. Published online August 31, 2001

Abstract PDF: The study evaluated the effectiveness of intervention for male adolescent smokers by making an assessment in terms of changes in food habits, nutrition knowledge, plasma catalase, superoxide dismutase(SOD), glutathione peroxidase peroxidase(GSH-px) activities and thiobarbituric acid reactive substance(TBARS) after Vit C supplementation and nutrition education. The subjects, male adolescent smokers, were assigned into four groups : Control group(19 students), education(Educ.) group(19 students), Vit C supplementation (suppl) group(19 students), and Educ. + Vit C suppl. group(19 students). The Educ. group and Educ. + Vit C suppl. group received nutrition education once a week for 2 weeks. The Vit C suppl. group Educ. + Vit C suppl. group received 500 mg ascorbic acid for 35 days. All data were collected before intervention and after intervention. Nutrition knowledge of those who received education increased, and the frequency of fruit and yellow-green vegetable consumption also increased. Plasma antioxidant enzyme activities were not different except for the SOD activity in the Educ. + Vit C suppl. group, which was significantly increased. The plasma ceruloplasmin level of groups that received Vit C supplementation was reduced more than any other groups, and the specific ceruloplasmin ferroxidase activity of groups that received Vit C supplementation was elevated more than other groups. These intervention programs had an impact on food habits, nutrition knowledge, plasma antioxidant enzyme activities, and plasma TBARS in male adolescent smokers. Various nutrition education programs must be implemented for adolescent smokers, and further studied are needed regarding sorts and amount of antioxidant nutrients and supplementation duration.

Dietary Intakes, Serum Lipids and Hematological Indices in Female Adolescent Smokers: Jung Hee Kim, Hee Won Lee, Kyung Won Kim; Korean J Community Nutr 1999;4(2):149-156. Published online June 30, 1999

Abstract PDF: This study was due to investigate the dietary intakes, serum lipids and other hematological indices in female adolescent smokers. The subjects were 85 smokers, whose average pack-year(smoking years on the basis of one pack of cigarettes per day) was 1.26 and 87 nonsmokers who were female high school students in Seoul. An anthropometric measreument was performed and % body fat was also analyzed by the Bioelectrical Impedance Fatness Analyzer(GIF-891). Dietary intakes and food habits were examined through questionnaires and nutrient intakes were analyzed by the Computer Aided. Nutritional analysis program for professional(CAN-pro). Serum TG, HDL-cholesterol and total-cholesterol levels were measured with test kits. Serum glucose, albumin, GOT and GPT were measured by automated dry chemistry system, SPOTCHEM 4410. Hemoglobin, hematocrit, RBC, WBC and MCV were determined by Semi Automated Microcell Counter(F-520). All data were statistically analyzed by SAS PC package program. There was no significant difference in the anthropometric measurements between smokers and nonsmokers. The caloric intake in adolescent smokers tended to be higher than that of nonsmokers but the difference was not statistically significant. In addition, there was no significant difference between smokers and nonsmokers in biochemical indices. Analysis of serum lipids showed that the serum levels of total-cholesterol and LDL-cholesterol of nonsmokers were unexpectedly significantly higher(p<0.05) than those of smokers. Overall results indicate that smoking itself with short pack-year in healthy female adolescent did not seem to influence apparent health and nutritional status.
