Comparison of Anthropometry, Serum Lipid Levels and Nutrient Intakes of Two Groups Based on their Drinking, Smoking, Exercise, Menopause and Obesity Status: In Residents of Youngdong Area: Hae Won Nam, Eun Kyung Kim, Un Hyung Cho; Korean J Community Nutr 2003;8(5):770-780. Published online October 31, 2003

Abstract PDF: The purpose of this study was to compare the anthropometry, the serum lipid levels and the nutrient intakes of two groups according to their alcohol intake, smoking habits, regular exercise patterns, menopause status and obesity levels. The subjects consisted of 180 clinically normal adults (males 89, females 91) in the Youngdong area. There were significant differences in the triglyceride (TG) concentrations between the alcohol consumers (169.3 +/- 130.0 mg/dl) and the non-alcohol consumers (111.4 +/- 64.5 mg/dl), and the smokers (165.0 +/- 103.6 mg/dl) and the non-smokers (110.8 +/- 39.0 mg/dl). Although regular exercise did not affect the serum lipid levels, the dietary intakes of cholesterol, niacin and phosphate were significantly higher (p < 0.05) in the male exercising group than in the male non-exercising group ; and female exercising group consumed more polyunsaturated fatty acids (p < 0.05) than the female non-exercising group. The waist/hip ratio, serum total cholesterol (198.4 +/- 36.3 mg/dl) and serum LDL-cholesterol (119.5 +/- 34.9 mg/dl) levels of the postmenopausal females were significantly higher than those of the premenopausal females (p < 0.01). The obese males showed higher serum cholesterol, LDL-cholesterol, LDL/HDL, and relative cholesterol levels than those of the normal-weight males ; and the obese females showed higher serum TG levels than that of the normal-weight females (p < 0.01). These results suggested that drinking, smoking, menopause and obesity are risk factors for hyperlipidemia. Thus, moderation in alcohol consumption, non-smoking, regular exercise and the maintenance of normal weight are necessary to prevent hyperlipidemia in middle-aged people.

Relationship between Nutrient Intake and Biochemical Markers of Bone Metabolism in Korean Postmenopausal Women: Haeng Shin Lee, Da Hong Lee, Chung Ja Sung; Korean J Community Nutr 2001;6(5):765-772. Published online December 31, 2001

Abstract PDF: To delineate the relationship between the nutrient intake from diet and the serum biochemical markers of bone metabolism, 56 postmenopausal women of 50 to 77 years of age were recruited. The biochemical markers including osteocalcin, calcium, phosphorus, estradiol and free testosterone were measured in fasting blood. Bone mineral density(BMD) was measured also by dual energy X-ray absorptiometry, and the nutrient intake of earth individual subject was estimated by 24-hour recall of 3 days. The age of the subjects was 64.8 +/- 7.7 years, and the BMDs of the subject were 0.86 +/- 0.26g/cm2(Lumbar spine), 0.60 +/- 0.10g/cm2 (Femoral neck), 0.49 +/- 0.10g/cm2(Trochanter), and 0.41 +/- 0.14g/cm2(Ward's triangle). There were no significant differences among age and nutrient intake level groups due to the small sample size. The biochemical markers showed certain degree of relationship with nutrient intake levels. The results were compared among 3 groups with different nutrient intake level classified by the percentage of Recommended Daily Allowances(RDA) for Koreans as follows low < 75% RDA, 75% RDA < or = adequate< 125% RDA, high > or = 125% RDA. The low energy and low riboflavin groups showed significantly higher serum osteocalcin levels than those of the high intake groups(p<0.05). On the other hand, there was a trend for serum Ca level to be higher with high nutrient intake. In this case, protein and thiamin were the only nutrients that reached a statistical significance(p<0.05). And the groups with low intake for protein and Ca showed significantly lower serum free testosterone levels than that of other intake groups(p<0.05). This study suggests an important role of nutrient intake levels on blood biochemical markers of bone metabolism.

Serum Lipids by Gender, Age and Lifestyle in Korean Adults: Mi Kyung Kim; Korean J Community Nutr 2000;5(1):109-119. Published online March 31, 2000

Abstract PDF: The purpose of this study was to measure serum lipids concentrations by gender and age, and to investigated the relation of serum lipids levels to cigarette smoking alcohol intake exercise and menopausal status in Korean adults. The subjects consisted of 463 healthy adult(29- men and 173 women) volunteers who were visiting the health Promotion Center in the Asan Medical Center from July 1, 1994 to July 22, 1994 Subjects were ambulatory free-living people and aged 20- 80 years, Anthropometric measurement was performed and serum triglyceride(TG), HDL-cholesterol and total cholesterol(TChol) concentrations were measure by automatic system(Hitachi 736-40). Data on life styles were obtained using structured questionnaires issued by a trained interviewer, All data were statistically analyzed by PC-SAS(Version 6.04) Serum concentrations of triglyceride and total cholesterol was higher(p<0.05) in men than in women, and serum HDL-cholesterol was lower(p<0.05) in men than in women. The prevalence of hyperlipidemia(TG>170 mg/dL and TChol>220 mg /dL) was 12.5% in men and 4.1% in women. The levels of serum triglyceride, total cholesterol and BMI increased with age in women. The distribution curves of serum triglyceride, total cholesterol and LDL-cholesterol of women were located in lower increased more rapidly with aging than in men, The distribution curves of BMI of women increased with aging after the thirties, The BMI of women was located in higher levels than of men in their sixties. The serum concentration of triglyceride and total cholesterol of male current-smokers and non-smokers were significantly(p<0.05) higher than those of ex-smokers. The concentrations triglyceride the male current0drinkers were higher(p<0.05) than those of male non-drinkers. In non-smokers and non-drinkers, serum TG concentration were lower (p<0.05) than those of current-smokers and current-drinkers. In exercisers, the serum triglyceride concentration was significantly(p<0.05) lower than in non-exercisers. In postmenopausal woman BMI and serum concentrations of TChol, TG and LDL-Chol were significantly by age and gender and smoking alcohol drinking, exercise and menopausal staus might be a better indicator to predict serum lipids in both genders.
