본 연구의 목적은 생활습관 요인 인자들과 (흡연, 비운동, 복부비만 등) 현대사회에서 가장 흔히 발생하는 10대 암 사망률과의연관관계를 조사 하는데 있었다. 생활습관 요인 인자들은 0, 1, 2, 3 종류의 통합된 생활습관 형태로 분류하였다. 건강한 남자들을(N=24,723; 연령, 20-80세), 평균적으로 14.5년 동안 추적 조사한 결과, 244명이 10대 암으로 인해 사망하였다. 나이 및 모든 공 변량 변수들을 통제한 후, 콱스(Cox) 비례위험 회귀분석을 이용하여 생활습관 요인 인자들과 10대 암 사망률과의 연관관계를 조사분석한 결과, 금연과 운동, 그리고 정상적인 복부둘레를 유지한 남자들이, 흡연과 비운동, 그리고 복부비만을 유지한 남자들에 비해, 10대 암으로 인한 사망률이 73%나 낮게 나타났다. 또한, 이 세 가지 좋은 생활습관을 유지한 남자들이 나쁜 생활습관을 유지한 남자들에 비해 평균수명이 8년이나 길게 나타났다. 암 예방 측면에서 보았을 떼, 만약 나쁜 생활습관을 유지한 남자들이 좋은생활습관을 유지하였더라면, 대략 53%가량의 남자들이 10대 암으로 인한 사망으로부터 생명을 구 할 수 있었다고 예측할 수 있다. 결론적으로, 흔히 발생하는 10대 암을 예방하기 위해서는, 금연과 운동, 그리고 정상적인 복부둘레를 유지 하는 것이 중요하며, 또한 수명을 연장하는데도 중요한 역할을 한다고 보인다. 특히, 평생 좋은 생활습관을 유지 하는 것은 웰빙의 근원이며 무병장수의 초석이 될 것으로 보인다. Cigarette smoking, physical inactivity, and obesity are key modifiable risk factors for most common??cancers. We examined the combined effects of these risk factors on the most common cancer mortality (top 10 leading??cancers) in men. This was a prospective cohort study using data from 24,723 men (aged 20-80 years). We classified a low-risk??profile as never smoked, moderate or high fitness, and normal waist girth, and further categorized them as 0, 1, 2, or 3??combined low-risk factors. During an average of 14.5 years of follow-up (358,055 person-years), there were 244 most common??cancer deaths. Cox proportional hazards regression was used to examine the association between the number of low-risk??factors and the 10 leading cancer mortality in men. After adjustment for multiple risk factors, men who were physically fit, never??smoked, and had a normal waist girth had a 73% lower risk of the 10 leading cancer mortality (95% confidence interval??[CI], 56%-83%) compared with men with zero low-risk factors. Men who maintained these three low-risk factors had an 8 year??(95% CI: 5.4-11.0) longer life expectancy as compared with men with none of these low-risk factors. Approximately 53% (95%??CI, 37%-64%) of the 10 leading cancer deaths might have been avoided if the men had maintained these 3 low-risk factors.??Maintaining a normal waist girth, being fit, and never smoking is associated with lower risk of the most common cancer mortality??in men.

Purpose: This study was conducted to investigate the wearing dentures status of the elderly and understand the relationship between demographic sociological properties, oral health care habits, lifestyle, and whether they wears dentures or not. Methods: In a surveying of 349 elderly who lives in Daegu and Kyung-pook, following results are obtained. Results: Wearing dentures rates of the aged are 58.5%. The more the aged is female(p=0.025), elderly(p=0.000), a low education level(p=0.000), no job(p=0.006), and a solitary person(p=0.016) the higher rate they wears dentures. The more the aged brushes their teeth after each meal(p=0.029) and uses the oral health devices(p=0.000) the lower rate they wears dentures. The more the aged have dinner alone(p=0.009), do not kept up with the exercises (p=0.000), and would like to dine off a soft food(p=0.000) the higher rate they wears dentures. Conclusion: This study showed that an old people's condition of oral health care who live in Daegu Kyungpook is very serious. Therefor not only an elderly but other aged people is need of constant and organized education for taking their oral health care habits and changing their lifestyle. Because wearing dentures rates of the aged by demographic sociological properties, oral health care habits, and lifestyle is lower.

신말연(Mal Ryun Shin),이종도(Chong Do Lee),강호율(Ho Yul Kang),오덕자(Duk Ja Oh),최혜진(Hea Jin Choi) 한국무용과학회 2008 한국무용과학회지 Vol.16 No.-

본 연구는 16세에서 24세의 여학생 167명으로 전공별 무용, 즉 한국무용(n=65), 현대무용(n=45), 발레(n=57)대상자로 골밀도를 분석하였다. 측정은 이중 에너지 방사선 골밀도 측정법(Dual Energy X-ray Absorptiometry, DEXA)을 이용하여 요추(Lumbar spine, L₂-L₄), 대퇴 경부(Femoral neck), 대퇴 전자부(Greater trochanter), 대퇴 삼각부(Ward's triangle) 를 측정하였다. 본 연구의 자료의 처리는 SAS(Statistical Analysis Systems) 통계 패키지를 이용하여 각 변인들 간의 평균값(M)과 표준편차(SD)를 산출하였고 일반 선형 모형 General Linear Model (GLM)을 이용하여 골밀도에 연령, 월경의 규칙과 불규칙, 초경의 나이, 운동경력, BMI를 보정한 후, 비교분석하였으며, 사후분석은 Scheffe를 이용하였다. 총 요추의 평균 골밀도를 살펴본 결과, 무용유형별 집단 간의 유의한 차가 있는 것으로 나타났다(p<.001). 이를 사후분석한 결과, 현대무용집단의 평균 골밀도가 한국무용 및 발레집단보다 높은 것으로 나타났다(p<.05). 골밀도에 영향을 주는 여러 인자들을 통제한 후, 총 대퇴 골밀도(Proximal femur)를 비교한 결과에서도 현대무용집단이 발레 및 한국무용집단보다 높은 골밀도를 보여주고 있다(p<.05). 결론적으로, 무용유형별로는 현대무용이 발레, 한국무용에 비하여 골밀도가 높은 것으로 나타났고, 발레와 한국무용은 골밀도에 유의한 차가 없다고 볼 수 있으며, 현대무용이 요추 및 대퇴부의 골밀도에 긍정적인 영향을 미치는 것으로 사료된다. This study examined the association between dancing types and bone mineral density (BMD) in female high school and college students. The subjects comprised of 167 female dancers (aged 16 to 24 years): ballet (n=57); Korean dance (n=65); modern dance (n=45). Duel energy x-ray absorptiometry(DEXA) was used to measure areal bone density in lumber spine (L2-L4), femoral neck, femoral trochanter, and Ward's triangle. BMD in lumber spine was estimated using an arithmetic average of L2-L4 and BMD in proximal femur was calculated using an average of femoral neck, femoral trochanter, and Ward's triangle. General linear models were used to test mean differences of BMDs across ballet, Korean dance, and modern dance categories with adjustment for covariates. Schefee's post-hoc tests were used to detect mean differences across different dance categories. After adjustment for age, menstrual abnormality, age at menarche, years of exercise, and body mass index, there were significantmean differences in lumbar spine (p<0.001), proximal femur (p<0.001), femoral neck (p<0.001), trochanter (p<0.001), and Ward's triangle (p=0.004), respectively, across ballet, Korean dance, and modern dance categories. Modern dancers had greater BMDs in lumber spine, proximal femur, trochanter, and Ward's triangle when compared with ballet and Korean dancers (p<0.05), but there were no statistical differences in these BMDs between Ballet and Korean dancers. For the femoral neck, modern dancers had a greater BMD as compared with Korean dancers, but had a similar BMD as Ballet dancers. We conclude that modern dancers had better BMDs in lumber spine and proximal femur as compared with ballet or Korean dancers.

이 연구의 목적은 새로 개발된 삼축 가속도계인 T-REX의 신체활동량 추정에 대한 타당도를 준거 도구(가스호흡분석기)와 참고 도구(가속도계)와의 비교를 통해 검증하는 것이다. 건강한 20대 남녀 50명은 운동자각인지도 12-14 수준으로 훌라후프, 스텝박스, 줄넘기와 제자리 걷기를 수행하였다. 대상자들은 운동을 수행하는 동안 T-REX(발목, 상완, 가슴, 허리, 손목 위치)와, ActiGraph(허리 위치), Actical(허리, 가슴 위치)을 착용하였으며, 산소섭취량이 동시에 측정 되었다. 타당성은 피어슨 상관계수로 분석하였다. T-REX는 발목, 가슴, 허리 위치에서 스텝박스 운동과(r=.83-.91) 훌라후프 운동 시 상완과 손목 위치에서(r=.82-.84) 산소섭취량과 매우 강한 상관관계를 보였으며, 제자리 걷기 운동 시에는 상완과 손목에서 보통이상의 상관관계(r=.63-.71)를 나타내었다. T-REX는 두 종류의 참고도구와 비교했을 때 산소섭취량과 더 높은 상관관계를 보여, 신체활동 검사 도구로 충분히 상용화될 수 있을 것으로 판단된다. This study examined the validity of the T-REX accelerometer to measure physical activity in men and women comparing with Actigraph and Actical. Fifty healthy men and women completed four different types of exercise (step box, jump rope, Hula hoop, and on-site walking) at a perceived exertion intensity rated 12-14. Oxygen uptake (VO₂) were assessed from all participants while assessing physical activity using T-REX (attached at the ankle, arm, chest, waist, and wrist) and, simultaneously, Actigraph (attached at waist) and Actical (attached at the waist and chest), respectively. VO₂ was measured using the Cosmed K4b2 portablesystem. There were very strong to strong associations between T-REX and VO₂ measured during Step box activity (T-REXs were attached at the ankle (r=.91), chest (r=.83), and waist (r=.86). There were also strong associations between T-REX and VO₂ measured during Hula hoop activity (T-REXs were attached to the arm (r=.82) and wrist (r=.84). Also, there were significant associations between T-REX and VO₂ measured during on-site walking at five locations (r=.63-.71). When compared with ActiGraph and Actical, T-REX showed higher associations with VO₂, which indicates a superior instrument to measure physical activity. The T-REX has high validity with VO₂ to measure physical activity including Step box activity in three locations (ankle, chest, and waist), Hula hoop activity in two locations (arm, wrist), and on-site walking in one location (ankle).
