Analysis of Osteoporosis Risk-factor for Women after Menopause; Through the Free Medical-examination Campaign / 대한골다공증학회지

OBJECTIVES: We performed research and analysis to determine the risk factors of osteoporosis for women after menopause by conducting a survey and measuring the bone density through a free program to diagnose osteoporosis. SUBJECTS AND METHODS: Kyungpook National University organized and then started the free osteoporosis diagnosis program on May 11 in 2005. One hundred forty six women whose age was between the early forties and late eighties took the survey. The risk factors for osteoporosis were analyzed according to the data which was obtained from the survey. The measurements of the bone mineral density (BMD) of right calcaneus area were recorded by the use of ultrasound equipment. RESULTS: Within the results, between the advancing age (P=0.000) of subjects, the lower BMI (P=0.002), the more children (P=0.004), the breast fed longer (P=0.047), the individuals who had a lower age when menopause began (P=0.037) and their BMD showed significant correlation. CONCLUSIONS: The results express that the osteoporosis risk-factors for Korean women, despite the advancing age and the lower BMI as absolute factors, that the more children, the longer breast feeding and the lower the age that menopause began, would result in a lower density of bone.

Soroprevalência da infecção pelo vírus da Hepatite B em uma prisão brasileira / Seroprevalence of Hepatitis B virus infection in a Brazilian jail

Esta pesquisa objetivou estimar a prevalência do marcador do HBV e seus fatores de risco na população masculina carcerária da Penitenciária de Ribeirão Preto - SP, Brasil. De 1.030 presidiários, foram sorteados 333 participantes, os quais foram submetidos à aplicação de um questionário e à coleta de sangue, no período de maio a agosto de 2003. Para diagnóstico de exposição ao HBV foi utilizado o ensaio imunoabsorvente de ligação de enzimas (ELISA) para detecção dos marcadores HBsAg, anti-HBsAg e anti-HBc total. A prevalência total de infecção pelo HBV nos presidiários foi de 19,5 por cento (IC95 por cento: 15,2 - 23,8). A média de idade dos participantes foi de 30,1 anos. Na análise univariada, a infecção pelo HBV esteve associada à idade acima de 30 anos (p<0,001), uso prévio de drogas injetáveis (p<0,001) e compartilhamento de agulhas prévio (p<0,001). Em um modelo multivariado, de regressão logística, a infecção pelo HBV foi associada à idade acima de 30 anos (OR = 3,3: IC95 por cento: 1,8 - 6.1) e uso prévio de droga injetável (OR = 2,7; IC95 por cento: 1.9 - 6.4). Infecção pelo HBV nas prisões representa grave problema de saúde pública, principalmente relacionado à idade acima de 30 anos e uso prévio de drogas injetáveis.

This survey aimed to estimate the prevalence of HBV serological markers and risk factors for this infection in male inmates at the Penitentiary of Ribeirão Preto, State of São Paulo, Brazil. Out of 1030 inmates, a simple random sample of 333 participants answered a questionnaire and had blood samples collected, from May to August 2003. Enzyme-linked immunosorbent assay (ELISA) was used to diagnose HBV infection (HBsAg, anti-HBsAg, and total anti-HBc). The overall prevalence for HBV markers in inmates was 19.5 percent (CI95 percent: 15.2 - 23.8). The participants' mean age was 30.1 years. In univariate analysis, HBV infection was associated with age > 30 years (p<0.001), previous injecting drug use (p<0.001) and previous sharing of needles (p<0.001). In a logistic regression multivariate model, HBV infection was associated with age > 30 years (OR = 3.3; CI95 percent: 1.8 - 6.1) and previous injecting drug use (OR = 2.7; CI95 percent: 1.9 - 6.4). HBV infection on prisons represents a major health problem, mainly associated with age over 30 years and previous injecting drug use.

Risk fators of stunting in some communes of ecological regions in Viet Nam

Based on the results of the household cross-sectional study on stunting and its risk fators during 2002-2003 in 32 communes of 8 regions in Viet Nam, authours focused on analyzing the relation between stunting and socio-economic factors at household level. The results of logistic regression showed that stunting was closely related to the height of mother, BMI of mother, birth intervals, and parent’s education level. Children who were sick in the first year of life were at higher risk with stunting (OR=2.5).There was also a strong relation between stunting and household’s living standards (stunting rates were 13,1%, 24,1%, 30.2%, 38.0% and 44.2% in the richest, the mid-upper, the middle, the low-mid and the poorest quintiles, respectively).

Nutritional Risk Factors, Perceptions on Nutrition and Health, Nutritional Knowledge, Food Habits and Their Correlation to Supplement Use in Middle-Aged and Elderly Koreans / 대한지역사회영양학회지

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.
