  • Early prevention of sarcopenia can be an important strategy for muscle maintenance, but most studies target subjects at slightly pre-sarcopenic state. Our previous paper describes the effect of protein supplements rich in leucine and vitamin D on muscle condition, and in this paper, we performed a sub-analysis to evaluate who benefitted the most in terms of improvement in muscle health. A 12-week randomized clinical trial of 120 healthy adults (aged 50 to 80) assigned to an intervention group (n = 60) or control group (n = 60) were analyzed. Subjects in the intervention group received, twice per day, a protein supplement containing (per serving) 800 IU of vitamin D, 20 g of protein (3 g of total leucine), 300 mg of calcium, 1.1 g of fat, and 2.5 g of carbohydrate. The subjects were classified into 'insufficient' and 'sufficient' groups at 25-hydroxyvitamin D (25[OH]D) value of 30 ng/mL. The skeletal muscle mass index normalized to the square of the skeletal muscle mass (SMM) height (kg/m2) increased significantly in the 'insufficient group' difference value of change between weeks 0 and 12 (Δ1.07 ± 2.20; p = 0.037). The SMM normalized by body weight (kg/kg, %) was higher, but not significantly, in the insufficient group (Δ0.38 ± 0.69; p = 0.050). For people with insufficient (serum 25[OH]D), supplemental intake of protein and vitamin D, calcium, and leucine and adequate energy intake increases muscle mass in middle-aged and older adults and would be likely to exert a beneficial effect on muscle health.

  • The purpose of this study was to investigate nutritional risk factors, perceptions on nutrition and health, nutritional knowledge, flood habits and their correlation to supplement use in middle-aged and elderly Koreans. A nationwide survey was conducted in the metropolitan areas (6 cities) and middle-sized cities (8 cities) of Korea from October to December, 2000. Subjects were randomly selected based on population, and 2,188 non-institutionalized adults aged over 50, and elderly (male 765, female 1,423) were studied. Data were collected using a standardized questionnaire administered in personal interviews. Nutrition and health-related scores of nutritional risk factors, perceptions on nutrition and health, nutritional knowledge, and flood habits were significantly higher in supplement users as compared to non-users. There was a negative correlation between nutritional risk factors and other nutrition and health-related scores on perceptions on nutrition and health, nutritional knowledge, flood habits, and pocket money. Also there was a positive correlation between nutritional risk factors and age. Therefore, these results may provide basic information for proper supplement use by middle-aged and elderly koreans.

  • Purpose: This study investigated the factors influencing sleep quality in adults according to age groups. The escriptive study was conducted in metropolitan areas of South Korea to control for possible sleep differences between adults living in rural areas and those living in cities. Participants were 450 adults between 19 and 65 years old. Methods: Self-administered questionnaires consisting of including the Korean Modified Sleep Leeds Evaluation Questionnaire, the International Physical Activity Questionnaire and the Perceived Stress Scale were used to assess the quality of adults' sleep. Results: Sleep quality was poor across the all age groups Stress and subjective health status were influencing factors of sleep quality among participants in their 20s; subjective health status and circadian rhythm (evening-type) were influencing factors of those in their 30s; subjective health status, alcohol consumption, and work days of less than 8 hours were influencing factors among participants in their 40s; and stress, circadian rhythm (evening-type), subjective health status, work days of over 11 hours, past smoking habit, and light physical activity were influencing factors of those aged 50 years and over. Conclusion: The quality of sleep was low across the all adult age groups in South Korea. Although the factors influencing quality of sleep differed by age groups, they in general indicate the need to focus on maintaining and controlling health status in sleep interventions.

  • The purpose of this study was to compare cerebral blood flow between hyperlipidemic patient group and normal healthy aldult group using transcranial doppler ultrasonography(TCD). I investigated cerebral blood flow of 63 hyperlipidemic patients and 42 healthy adults. To evaluate the cerebral blood flow, I measured the systolic peak velocity(Vs) and mean flow velocity(Vm) of the milddle cerebral artery(MCA), anterior cerebral artery(ACA), posterior cerebral artery(PCA), basilar artery(BA), internal carotid artery(ICA) in the two groups using TCD. In normal healthy adults, subjects showed a decerease in Vs and Vm with advancing in age. There was a significant difference in the Vm of ICA. There was no significant differences in the Vm of ACA and ICA. In normal healthy adults, females showed high velocities of all examined vessel. There was a significant difference in the Vs of ICA. There was a significant differences in the Vm of MCA and ICA. Normal healthy adults higher than hyperlipidemic patients in the Vs of MCA, ACA, PCA. There was no significant difference in the Vs of all exmined vessels. Hyperlipidemic patientsincrease higher than normal healthy adults in the Vm of ACA. There was a significant difference in the Vs of BA. In the patients aged under 50's, normal healthy adults higher than hyperlipidemic patients in the Vs and Vm except BA. But there was no significant difference in all exmined vessels. In the patients aged over 50's, hyperlipidemic patients higher than normal healthy adults in all examined vessel expect PCA. There was a significant difference in the Vs of BA and ICA. And hyperlipidemic patients higher than that normal healthy adults in all exmined vessels. There was a significant difference in BA and ICA. In this study, visible differences in blood flow between hyperlipidemic patient group and normal healthy aldult group were shown. However, these results do not come up to the previous values that were reported and known worldwide.

  • The purposes of this study were to investigate use patterns of nutrition information service of 50-and-older adults and analyze the differences in use patterns of nutrition information service according to their socio-demographic variables. The survey was conducted with 500 adults aged 50-and-over living in Seoul between March 28 and April 10, 2007. A total of 401 questionnaires were used for analysis (use rate 80.2%) and the statistical data analyses were completed using SPSS Win (ver 12.0). The main results of this study were as follows. First, most respondents (73.3%) realized the need for nutrition counseling or education. However, 65.3% of respondents have little experience in nutrition counseling or education. Second, the most preferred methods of nutrition counseling or education were field trips (27.7%), counseling in hospitals/public health centers (23.4%), cooking classes (23.2%). And the most often cited sources of nutrition information were TV/radio (66.6%) and newspapers/magazines/books (41.6%). Third, sociodemographic variables such as sex, age, education level, occupations were significantly related to methods of nutrition counseling or education. And variables such as age, education level, occupations were significantly related to often cited sources of nutrition information. Also sex, age, education level, occupations were significantly related to needs for nutrirtion information service.

  • Nasopharyngeal carcinoma (NPC) is the second most common neoplasm of head and neck in Tunisia. The distribution is bimodal with a first period occurrence between 15 and 20 years old and a second peak at around 50 years of age. Undifferentiated carcinoma of nasopharynx type III (UCNT) is the predominant histological type (93.4%). Data of cancer registry of North Tunisia confirmed that it is an intermediate risk area for NPC with overall ASRs of 3.6 and 1.6/100,000 respectively in males and females. This study aimed to present the evolution of incidence rate of nasopharyngeal carcinoma over a period of 12 years (1994-2006). Data of cancer registry of North Tunisia (NTCR), covering half of the Tunisian population, were used to determine evolution of NPC incidence, calculated by 5 year periods. The estimated annual percentage change (EAPC) was used as an estimate of the trend. To best summarize the behavior or the data trend across years, we used a join-point regression program. Between 1994 and 2006, we observed negative annual average change of standardized incidence in men and women (-3.3%and -2.7%) also for the standardized incidences which showed a rather important decline (26.4% in males and 22.3% in females). The truncated age standardized incidence rate of NPC in adults aged of 30 years old and more (N= 1209) decreased by -0.4% per year from 1994 to 2006 over time in north Tunisia dropping from 6.09 to 4.14 person-years. However, the rate was relatively stable during this period among youths aged 0-29 years (N= 233) in both sexes. NPC demonstrated a favorable evolution from 1994-2006 probably due to a improvement in socioeconomic conditions.

  • 본 연구는 성인영양지수 조사지를 바탕으로 북한이탈주민의 전반적인 식사의 질을 평가하고자 진행되었다. 특히 연령대별 식품 섭취 빈도와 식습관 및 식행동, 영양 지수의 차이를 분석하였다. 대상자는 서울 및 경기 일부 지역의 만 19-64세 성인 166명을 대상으로 진행되었으며 각 연령대별로 20대 41명, 30대 41명, 40대 41명, 50대이상 43명으로 연령대를 평준화하였다. 연령대가 낮을수록 라면, 패스트푸드, 과자 (초콜릿, 사탕 포함), 달거나 기름진 빵 (케이크, 도넛, 단팥빵 등), 가당 음료 등 고에너지 식품 섭취 빈도와 외식, 야식 섭취 비율이 높은 것으로 나타났다. 또한 20대 연령대에서 총점 NQ, 절제 영역 총 점수가 낮고 등급은 '하'로 판정된 비율이 높았다. 50대 연령대에서 절제영역의 점수가 높게 나타난 원인은 라면, 패스트푸드, 과자, 달거나 기름진 빵, 가당 음료 등과 같은 고에너지 식품 섭취 빈도도 낮기 때문인데, 이는 이 집단이 절제력있는 식사를 하고 있는 것으로 비춰질 수도 있으나 중년층에서 패스트푸드, 라면과 같은 식품의 기호도가 낮아 아예 섭취 고려 대상이 아니라는 점에 주목해야 한다. 본 연구에서 주목해야 할 점은 연령이 낮을수록 식사의 질이 매우 열악하게 나타나 식사의 질 개선을 위한 맞춤형 영양 교육 프로그램 개발 및 보급의 필요성을 시사한다. 이에 본 연구의 결과와 시사점이 북한이탈주민의 건강 증진을 위한 영양 교육과 이를 위한 정책 마련의 기초자료로 활용되기를 기대한다.
