This study investigated anthropometric and biochemical characteristics, nutrient intakes, and bone density of Korean elderly men (over 65 yrs). Data on bone density and anthropometric (height, weight, waist circumference, body mass index and blood pressure) and biochemical (total cholesterol, high-density lipoprotein (HDL)-cholesterol, low-density lipoprotein (LDL)-cholesterol, triglyceride and hemoglobin) characteristics, nutrient intakes, and nutrient density were obtained from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES, 2008∼2011). Subjects were categorized into smoking and non-smoking groups, and smoking groups were divided into three groups by smoking period (under 20 yrs, 21∼40 yrs and over 41 yrs). Serum triglyceride concentrations of the smoking group aged 21∼40 yrs were higher than those of other groups (P＜0.01), whereas other biochemical factors were not different. Intake ratios of energy, protein, phosphorus and sodium in subjects were over 100% of Dietary Reference Intake for Koreans (KDRI). Nutrient densities according to intakes of thiamin, riboflavin, and niacin per 1,000 kcal were significantly different among the groups (P＜0.05). Bone density of subjects decreased according to smoking period (T-score of total femur in non-smoking group -0.3108, and -0.2918, -0.4941, -0.6847 in smoking group, respectively). Ratio of osteoporosis was 38.1% in the non-smoking group and 44.4%, 51.1%, and 64.0% in the smoking group, respectively. The findings of the present study show that smoking may be associated with bone health, higher ratio of osteoporosis, and low nutrient density in elderly men. Therefore, practical and systematic non-smoking programs are required to improve the bone density of elderly men as well as maintain healthy bone levels and desirable lifestyle.
