본 연구는 제 5기 2차년도(2011) 국민건강영양조사 자료를 이용하여 서울 ·경기지역 조사대상자 중 30~80세 여성 513명을 선정하여 골밀도, 혈압, 칼슘섭취 상태를 파악하고 그 관련성을 연구하였다. 대상자의 골 건강도에 따라 일반사항, 신체계측, 골밀도, 혈압, 혈액생화학적 특성, 영양소섭취량을 파악하였고, 칼슘을 포함한 무기질 섭취량과 제요인 간의 상관관계를 분석하였다. 그 결과를 요약하면 아래와 같다.
This study was carried out to investigate bone mineral density (BMD), blood pressure, calcium, sodium intake and related biochemical variables, and to analyze the relationship between BMD, and blood pressure, physical characteristics, nutrient intakes of Korean adult women. The study subjects were 30~80years old, 513 women living in Seoul and Kyunggi area who participated in 2011 KNHANES. The study subjects were divided into three BMD groups; normal, n = 259 (50.4%), osteopenia, n = 169 (32.9%), and osteoporosis, n = 85 (16.7%). Average height and weight and fat free mass decreased with a decrease in BMD. Average BMD of normal, osteopenia, osteoporosis were 0.87, 0.79, 0.70 g/cm2, and T-score were 0.42, ?0.66, ?1.62, respectively. Higher systolic blood pressure, alkaline phosphatase, and triglyceride were significantly associated with a decrease in the BMD. The rates of hypertension were significantly increased from normal to osteoporosis. i.e. 18.5% in normal, 34.3% in osteopenia and 63.5% in osteoporosis. Average nutrientintakes such as protein, fat, calcium, phosphorus, iron, sodium, potassium, vitamin A, vitamin B, vitamin B2, and vitamin C were significantly lower in subjects with lower BMD.n. Average calcium intake of normal, osteopernia and osteoporosis were 528.50, 416.96, 389.56 mg, respectively. There were significant negative correlations between calcium, phosphorus and age, systolic blood pressure, triglyceride. Also, there were negative correlation systolic blood pressure (incomplete sentence). In this study, we found low BMD according to low calcium intake increase the risk of osteoporosis and hypertension rather than sodium intake, also calcium intake decreased with increase age. Therefore, in order to prevent osteoporosis and hypertension, subjects need to be educated regarding the importance of calcium nutrients in diet. (Korean J Community Nutr 18(3) : 269~282, 2013)
