Purpose: To investigate body compositons and bone mineral density(BMD) in college women and to find the relationship between them. Method: From January to March of 2001, BMD at four parts(forearm, lumbar, femur and whole body), body mass index(BMI), body fat mass(BFM), lean body mass(LBM) and body fat percentage(%Fat) were measured with the Dual Energy X-ray Absorptiometry. Other physical characteristics were measured with a scale, a height measurer, and questionnaires. Result: Grouping by the BMI, 43.2% showed low weight, and 5% over weight. When applying the percent Fat, 43.8 % was diagnosed as obesity group. The fact indicate that a majority of college women have unbalanced body composition with high percent Fat, compared to their body weight. Assessing the BMD with the WHO standards, 91.4～95.7% of the BMD of forearm and whole body was normal. But, 40.3% and 33.1～43.9% showed osteopenia at lumbar and femur, and 104 %, 0.7～7.2% showed osteoporosis. The BMD at all parts showed significant correlation each other(r=.29～.89, p=.001～.000). Body weight and BMI showed correlations to with BMDs at all parts of the body(r=.19～46, p=.025～.000; r=18～.45, p=.039～.000). But the percent Fat had a correlation with only femur neck BMD(r=.19, p=.024). Conclusion: This study showed a majority of healthy college women were exposed to the risk for osteoporosis. Additional study is required to develop nursing interventions to remove the risk factors of osteoporosis. In particular, the acquisition of balanced body composition is necessary, increasing body weight and BMI through the increase of LBM, not through the quantitative increase of BFM.

The purpose of this study was to investigate Bone Mineral Density(BMD) and affecting factors on BMD of college women in Seoul. The subjects were 47 healthy college women aged 18-25 years. Antrophometric and body fat measurements were performed by Bioelectrical Impedance Fatness Analyzer(Tanita TVF 202). Blood pressure and pulse frequency were measured. Dietary intakes and general living habits were examined through questionnaires and nutrient intakes were analyzed by Computer Aided Nutritional Analysis(CAN) program for professional. Serum total cholesterol, TG(triglyceride), HDL-cholesterol, total protein, albumin, GOT, calcium were measured by Spotchem(SP-4410). Serum osteocalcin and alkaline phosphatase(ALP) were measured to monitor bone formation. BMD of lumbar spine(L2-L4), right hip(neck, ward's triangle, trochanter) and right forearm were measured by Dual Energy X-ray Absorptiometry(DEXA). Muscle strength was measured by examining leg flexion strength(right and left), leg extension power(right and left), handgrip power(right and left) and back strength. All data were statistically analyzed by the SAS PC package program. BMD of college women was normal(by WHO, 1994). Their muscle strength was bad(by national fitness guidebook, 1995). Only a mall number of them exercised (32.6% of subjects). There was no significant difference among BMD, muscle strength and % body fat(p<0.05). There were significant differences between BMD and total cholesterol as well as TG and VLDL-cholesterol(p<0.05). Total cholesterol was associated with decreasing BMD of the right forearm(p<0.05). TG and VLDL-cholesterol are associated with increasing BMD of right hip ward's triangle(p<0.05). There were significant differences among BMD, ALP and serum total protein. ALP was associated with decreasing BMD of the right forearm(p<0.05). There were significant differences between BMD and Ca as well as between Na and K intakes (p<0.05). Intakes of Na and K were associated with decreasing BMD of the right forearm (UD)(p<0.05). There were significant differences between in BMD and pulse frequently and serum albumin (p<0.05). Serum albumin is associated with increasing BMD of L3-L4(p<0.05), right hip neck(p<0.05). %Body fat, TG, VLDL-C, Ca intake, pulse frequency and serum albumin were associated with increasing BMD(p<0.05). Intakes of Na and K, ALP, total cholesterol, total cholesterol, total protein and height are associated with decreasing BMD(p<0.05). Overall results indicate that Ca intake but to be moderate in protein and Na intakes in order to increase BMD. Body exercise was recommended to increase BMD as well.

Purpose: The purpose of this study was to review the literature to explore the relationship between body mass index (BMI) and bone mineral density (BMD) in elderly using an integrative review. Methods: The keywords 'osteoporosis,' 'body mass index,' and 'bone mineral density' were used to search peer-reviewed publications through four databases. Among 1,389 searched articles, eight articles were selected after excluding those that did not meet the inclusion criteria. Results: Seven articles stated that BMI was positively associated with BMD among elderly. In the elderly, the prevalence of osteoporosis was 25-55.7% in women, and 11-13% in men. Conclusion: This study found that high BMI may be helpful to increase BMD among elderly although the mechanism was not clear. It is necessary to identify BMD and fractures in elderly according to body composition in future research.

지방제외체질량(lean mass) 및 지방량(fat mass)과 같은 체성분이 골밀도에 미치는 영향은 매우 복잡하고 다양하게 나타나는 것으로 알려져 있다. 본 연구에서는 전국민을 대상으로 한 표본조사로부터 얻은 질병관리본부의 국민건강영양조사 2008-2011년 자료를 이용하여 50세 이상 남성(N=2,139) 및 폐경후여성(N=2,193)에서 체성분과 골밀도와의 관련성에 대해 조사하고자 하였다. 골다공증약물을 사용한 경우 및 골밀도에 영향을 미치는 질환 및 악성질환 등이 있는 대상은 제외하였다. 신체계측, 설문조사, 혈액검사 등과 함께 이중에너지흡수방사선을 이용하여 요추 및 대퇴골에서 골밀도를 측정하였고, 총지방제외체질량(TLM; total lean mass), 총지방량(TFM; total fat mass), 몸통지방량(TrFM; truncal fat mass) 등을 측정하였다. 체성분 지표들과 요추 및 대퇴골 골밀도는 유의한 양의 상관관계를 보였다. 연령, 체질량지수, 월 가구수입, 교육수준, 신체활동, 1일 칼슘섭취량, 혈중 비타민 D 농도를 포함하는 다중회귀분석을 시행한 결과 남녀 모두에서 TLM이 증가할수록 요추 및 대퇴골 골밀도가 유의하게 증가하였다. TLM의 가장 낮은 사분위수에 해당하는 군에서 요추 및 대퇴골 골밀도는 남녀 모두에서 다른 사분위수에 해당하는 군에 비해 유의하게 낮았다. TrFM은 위의 교란요인들을 보정한 이후 남성에서는 대퇴골전체 골밀도와 여성에서는 대퇴골경부 골밀도와 음의 상관관계를 보였다. 결론적으로 TLM은 50세 이상 남성 및 폐경후여성에서 골밀도를 유지하는데 매우 중요한 인자임을 확인할 수 있었다.

The purpose of this study was to investigate the effect of bone mineral density on life styles, dietary habits and nutrient intakes among the male college students. The subjects were divided into four groups; $Q_1$ (calcaneus BMD < 25 percentile, n = 117), $Q_2$ (25 percentile $\le$ calcaneus BMD < 50 percentile, n = 118), $Q_3$ (50 percentile $\le$ calcaneus BMD < 75 percentile, n = 118) $Q_4$ (calcaneus BMD $\ge$ 75 percentile, n = 116). And they were asked about general characteristics, life style, dietary habit, and nutrient intake using questionnaire and 24-hr recall method. They were measured the bone mineral density of calcaneus using quantitative ultrasound. The average age of the subjects of the study was 23.0 yews and the average height, weight, and BMI were 174.7 cm, 69.0 kg, $22.5 kg/m^2$. The bone mineral density in calcaneus was $0.43 g/cm^2$ in $Q_1,\;0.50 g/cm^2$ in $Q_2,\;0.56 g/cm^2$ in $Q_3$, and $0.69 g/cm^2$ in $Q_4$ (p < 0.001). The results showed that $Q_1$ tended to have irregular exercise compared to the other three groups. Compared with $Q_1$ and $Q_2$, the frequency of skipping breakfast was lower in $Q_3$ and $Q_4$. Also the results showed that the $Q_4$ was significantly more often to drink coffee compared with the other three groups (p < 0.01). The mean daily energy intake was 2210.6 kcal ($88.4\%$ of RDA). The intake of energy, vitamin $B_2$, calcium, and zinc did not meet the Korean RDA. Also the $Q_2$consumed significantly lower intakes of protein (p < 0.05) and plant protein (p < 0.05) compared to the $Q_3$ and $Q_4$. The $Q_1$ and $Q_2$ consumed significantly lower intakes of vitamin $B_2$ (p < 0.01) compared to the $Q_3$ and $Q_4$. In conclusion, male student in lower bone mineral density appeared to have unhealthy life styles and dietary habits in terms of irregular exercise, high frequency of skipping breakfast and lower intakes of protein, vitamin $B_2$ showing a strong need proper education on meal practices and exercise habits for the bone health.

골밀도 감소는 골다공증의 발생과 골절 위험성 증가 등을 유발하기 때문에 사회적인 건강문제로 대두된다. 골다공증은 사전 예방이 매우 중요하며, 골밀도가 감소되는 중년기 이후보다 골밀도가 형성되고 최고로 발달되는 시기인 청년기에 적극적인 관리와 예방이 중요하다. 골밀도에 영향을 주는 요인으로는 유전적요인, 신체적요인, 환경적 요인 등이 있다. 최근, 사회분위기가 많이 바뀌면서 생활습관, 식습관 등이 이전과는 달라지고 있다. 그러므로 이 연구를 통해 사회 분위기 변화에 따른 젊은 층의 생활습관 변화가 골밀도에 어떠한 영향을 미치는지를 파악하고자 한다. 본 연구는 동남보건대 재학생 중 여자 134명, 남자 75명(총 209명)을 대상으로 하여 골밀도 측정과 생활습관에 대한 설문조사를 병행하였다. 골밀도 측정은 이중에너지 X-ray 흡수장치(DEXA)를 사용하여 넙다리뼈 목(femoral neck)과 허리뼈(Lumbar spine, L1 ~ L4)부위를 측정하였다. 또한 생활습관에 대해서는 미리 작성한 설문지에 답하도록 하였다. 자료의 분석은 spss프로그램을 사용하였으며, 골밀도와 신장, 체질량지수의 관계는 상관분석 및 다중회귀분석을 이용하였다. 음주, 흡연, 운동 유무 집단에서의 차이는 t-test를 이용하여 검정하였다. 그 결과 다음과 같은 결론을 얻었다. 첫째, 체질량지수(BMI)에 따른 골밀도(BMD)의 비교에서는 통계적으로 유의한 차이가 있었으나, 음주, 흡연과 골밀도(BMD)와는 특별한 상관관계가 없었다. 둘째, 카페인 섭취량에 따라 골밀도가 낮아지는 경향이 나타났고, 특히 여성에게서 통계적으로 유의하였다. 또한 여성과 남성 모두 넙다리뼈 목에서 운동량과 통게적으로 유의한 상관관계를 보였다. 셋째, 식사습관에 따른 골밀도의 관계에서는 여성의 허리뼈에서 유의한 관계가 있었으나, 남성의 허리뼈와 여성의 넙다리뼈에서는 통계적으로 유의한 관계가 없는 것으로 나타났다(또한 다이어트와 골밀도도 통계적으로 유의한 관계가 없는 것으로 나타났다). 그러므로 골다공증을 예방하기 위해서는 식후 1시간 이내에 카페인을 섭취하는 것을 삼가는 게 좋다. 또한 걷거나 뛰기 등의 운동을 지속적으로 하면서, 영양이 균형 잡힌 식사를 하는 것이 골다공증을 예방하는 데에 도움이 될 것으로 사료된다.

This study was performed to evaluate the effect of sodium cholride supplementation on bone metabolism in female rats consuming a low calcium diet. Twenty five female rats were divided into three dietary groups (control Na : 0.1038%, 1% Na : 1.036%, 2% Na : 2.072%). All experimental diets contained 0.27% Ca and were fed to rats with deionized water for 7 weeks. Bone mineral density(BMD) and bone mineral content(BMC) of total body, spine and femur were measured using energy x-ray absorptiometry(DEXA) by small animal software. Then Ca efficiency was calculated from BMD and BMC. Serum Ca, P, Na and urine Ca, P, Na were determined. Urinary pyridinoline, serum ALP were measured to monitor bone resorption. Following 7 weeks, sodium cholride supplemented groups had higher urinary Ca excreteion, urinary pyridinoline, crosslinks value and serum ALP. There was no significant difference in case of serum Ca among all groups. Sodium chloride supplemnted groups had lower Ca effciency of total, spine and femur BMD and BMC than that of control group. In conclusion high salt intake not only increases urinary Ca excretion as urinary Na excretion does but also increase bone resorption and decrease Ca efficiency of each bone. It is been suggested that high salt intake may be harmful for bone maintenance. Therfore, the decrease of salt intake to the level of recommendation would be desirable.

The purpose of this study was to examine the effects of dietary green tea powder supplementation on bone metabolism in streptozotocin-induced diabetic rats. Thirty-two male Sprague-Dawley rats (body weight $210{\pm}3g$) were divided into two groups, diabetic and non-diabetic groups. Each group was randomly divided into two subgroups which were fed with the control and 1% green tea powder diets. The serum and urine concentrations of calcium and phosphorus were determined. Serum osteocalcin and ALP and urinary DPD crosslinks value were measured in order to monitor bone formation and resorption. Bone mineral density (BMD) and bone mineral content (BMC) were estimated using PIXImus in the spine and femur. Body weight gain and FER were lower in the diabetic group than in the non-diabetic group regardless of diets. The serum concentration of calcium and phosphorus were not changed among all groups. Urinary calcium and phosphorus excretion were higher in the diabetic group than in the non-diabetic group regardless of diets; however, they were not significantly different by green tea powder intake. Serum alkaline phosphatase (ALP) was increased in the diabetic group than in thenon-diabetic group. Further, there were no significant differences in serum osteocalcin and urinary deoxypyridinoline crosslinks value among all groups. The levels of spine and femur bone mineral density of the diabetic group were significantly lower than that of the non-diabetic group. Within the diabetic group, spine BMD was significantly higher in rats fed with the green tea powder diet than in rats fed the control diet. Therefore, this study suggests that green tea powder has a beneficial effect on bone health, although it is not directly applicable to humans.

The objective of this study was to investigate the effect of soymilk and exercise on bone mineral density (BMD) in underweight college women of 19-22 years of age, who had lower bone mass. The BMD of the lumbar spine and femoral neck was measured for 52 underweight college women. Among them, 33 subjects, whose t-score value was below -1, were selected. Questionnaire survey, anthropometrical measurements, dietary recall, analysis of BMD, fasting serum osteocalcin and urinary deoxypyridinoline (DPD) were conducted before and after the 10 week study. The 33 subjects were divided into 2 groups： soymilk group (n=19), and soymilk ＋ exercise group (n=14). The soymilk group was given 400$m\ell$ soymilk containing 60mg of isoflavones on a daily basis and the soymilk ＋ exercise group exercised three times a week with a daily intake of 400$m\ell$ soymilk for 10 weeks. The average ages of the soymilk group and the soymilk ＋ exercise group were 21.1 years and 20.4 years, respectively and, there were no significant differences between the soymilk group and the soymilk ＋ exercise group in the areas of height, weight or Body Mass Index (BMI). At the baseline, the mean daily energy intake of the soymilk group and the soymilk ＋ exercise group was 1,597.9kcal (79.43％ of RDA) and 1,704.2kcal (85.2％ of RDA), respectively. The mean calcium intake of the soymilk group (408.3mg) was not significantly different from that of the soymilk ＋ exercise group (389.4mg). Despite the 400$m\ell$ soymilk supplementation, there were no significant changes of nutrient intake in either group after treatment. However, there were significant increases in BMD's of lumbar spine and femoral neck in both groups. There were some increases in the serum osteocalcin level and decreases in the urinary deoxypyridinoline level as well. BMD change of the soymilk group was not significantly different from that of the soymilk ＋ exercise group. In conclusion, supplementary intake of soymilk (containing 60mg of isoflavones) resulted in a significant increase in the BMD's of the lumbar spine and femoral neck in underweight college women with low bone mass. However, exercise did not result in any significant changes in the BMD's, implying the necessity for more intensive and specific long-term physical training for any substantial changes. Further investigation is necessary to determine the exercise that most strongly affects BMD.
