Abstract

OBJECTIVES
This study was carried out to investigate bone mineral density (BMD), blood pressure, age and biochemical index and nutrient intakes, and to analyze the relationship between BMD, blood pressure, biochemical index, nutrient intakes of Korean women.
METHODS
The study subjects were 499 women with a age range of 30-79 years living in Seoul and Kyunggi area who participated in 2011 KNHANES. The study subjects were divided into 5 age groups: 30 years (145), 40 years (110), 50 years (102), 60 years (85) and 70 years (57), and 3 BMD groups: normal 258 (50.4%), osteopenia 163 (32.9%) and osteoporosis 78 (16.7%).
RESULTS
The average waist circumference, BMI and body fat increased with age, but fat free mass decreased with age. Average BMD and T-score was decreased from 0.84, 0.74 g/cm2 in 30 years to 0.05, -1.05 g/cm2 in 70 years. The rates of osteopenia and osteoporosis increased significantly 22% in 30~40 years, 47% in 50 years and 56% in 60~70 years. Systolic blood pressure and cholesterol were significantly increased with age. The rates of hypertension was significantly increased 2.1% in 30 years, 30.4% in 50 years 89.5% in 70 years. Average nutrient intakes such as protein, calcium, iron, vitamin A and C were significantly decreased with age. There were significant negative correlations between age and calcium, systolic blood pressure, triglyceride.
CONCLUSIONS
In this study, we found the risk of osteoporosis and hypertension were significantly increase with over 50 years age. Calcium and protein intake decreased with age. Therefore, in order to prevent osteoporosis and hypertension, adult women need to be educated regarding the importance of protein, calcium and other nutrients in their diet.
