ABSTRACT
Objetivo: identificar o conhecimento e as práticas de prevenção às infecções sexualmente transmissíveis (IST) entre homens jovens universitários. Método: estudo descritivo-exploratório, de natureza qualitativa, realizado em uma universidade pública. Participaram 20 universitários do sexo masculino, na faixa etária de 18 a 29 anos e sexualmente ativos. Realizou-se a coleta de dados por meio de um roteiro semiestruturado e os dados foram analisados pela técnica de análise de conteúdo temático-categorial. Resultados: apesar de os participantes reconhecerem que as IST são transmitidas pela prática do sexo desprotegido, a imprevisibilidade das práticas sexuais, a confiança na parceria sexual em relacionamentos estáveis e o consumo de bebidas alcoólicas são fatores que favorecem o não uso de preservativos. Testes diagnósticos e antirretrovirais são adotados em substituição ao uso de preservativos. Conclusão: o grupo populacional se expõe a riscos e carece de ações de educação em saúde e acesso a serviços de prevenção de doenças.
Objective: to identify the knowledge and prevention practices regarding sexually transmitted infections (STIs) among young male university students. Method: a qualitative nature descriptive-exploratory study, conducted at a public university. 20 sexually active male university students between 18 and 29 years old participated in the study. Data collection was conducted using a semi-structured script, and the data were analyzed using the thematic-categorical content analysis technique. Results: despite participants recognizing that sexually transmitted infections (STIs) are transmitted through unprotected sex, factors such as unpredictability of sexual practices, trust in sexual partners in stable relationships, and alcohol consumption favor the non-use of condoms. Diagnostic tests and antiretroviral medications are adopted as substitutes for condoms use. Conclusion: the population group exposes itself to risks and lacks health education initiatives and access to disease prevention services.

OBJECTIVES: The purpose of this study was to determine which factors influence the bone mineral density (BMD) of total femur (TF), femoral neck (FN) and lumbar spine (LS) of the adult men by analyzing nationally representative Korean survey data. METHODS: This study was conducted based on the data of 1,770 men aged 19-64 years from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES V), 2010~2011. The BMD was analyzed by various factors (general characteristics, anthropometric data, health habits, chronic diseases, nutrient intake status). SPSS statistics for complex samples was used to analyze the data. RESULTS: We observed that the BMD decreased significantly with aging. The BMD in each of the second lowest quartile of waist circumference (in TF & FN) and body mass index (in TF & LS) was lower than the respective BMD in the highest quartile group. The BMD in FN was higher in the group who reported the weight training. The BMD in LS was lower in hypercholesterolemia group than in the normal group. The BMD in TF, FN and LS was lower in hypertriglyceridemia group and in diabetes group than in the normal group. The BMD in TF, FN and LS was higher in the group with < Estimated Average Requirement iron intake. But there was no evidence to suggest that the BMD was related with educational level, income level, smoking, alcohol intake, anemia and nutrient intake status (except for iron). CONCLUSIONS: This study suggested that aging, waist circumference, body mass index, weight training, hypercholesterolemia, hypertriglycemia, diabetes were site-specifically associated with the BMD in TF, FN and LS in the adult men. These bone site-specific factors need to be considered for the prevention of osteoporosis.

O equilíbrio postural é importante na realização das tarefas diárias, exigindo que o sistema nervoso central organize as informações enviadas pelos sistemas sensoriais (visual, vestibular e somatossensorial) e interaja com o neuromuscular para funcionamento ideal. Ele pode ser quantificado através do centro de pressão ou do centro de massa. O centro de massa é a variável que nos permite analisar o comportamento do equilíbrio, enquanto o centro de pressão é o ponto representativo da resultante da aplicação de todas as forças no solo. Porém, o centro de massa é de difícil mensuração e pode ser obtido através de diferentes tipos de métodos, dificultando o entendimento da relação com o centro de pressão. Logo, o propósito do estudo foi verificar as correlações entre o centro de massa calculado por métodos cinemáticos e o centro de pressão em homens adultos na situação de equilíbrio estático. Participaram do estudo 10 homens adultos jovens. Para obtenção dos dados de centro de massa foi utilizado o sistema VICON de cinemetria. Os dados de centro de pressão foram obtidos através de uma plataforma de força AMTI OR6-6 1000. Foram analisadas as amplitudes de deslocamento e as velocidades médias de cada uma das variáveis, correlacionando-as através do teste de correlação Pearson. A força de correlação foi definida pelo critério de Malina e o valor de significância adotado para todos os testes foi de 0,05. As correlações entre as variáveis velocidade e amplitudes do centro de massa com as respectivas variáveis do centro de pressão foram todas fortes e significativas (p < 0,05), com maior força de correlação e significância para a situação de olhos fechados. Conclui-se que na análise do equilíbrio estático de homens jovens, tanto o centro de pressão quanto o centro de massa calculado por métodos cinemáticos são representativos.
The postural balance is very important on diary tasks, challenging the central nervous system to process and synchronize the data sent from sensory systems (visual, vestibular and somatosensory) and interact with neuromuscular system for a better performance. It can be quantified by the center of pressure or by the center of mass. The center of mass is the variable which provides the real measurement of balance control, while the center of pressure is the representative point of the resultant forces on the ground. However the center of mass is difficult to measure and can be calculated by different methods, making hard to understand the relationship with the center of pressure. Therefore, the purpose of this study was to verify the correlations between center of mass calculated by kinematic methods and center of pressure in adult men in static balance condition. 10 adult men participated of the study. To assess the center of mass position, VICON kinematics system was used. The data of center of pressure was obtained using an AMTI OR6-6 1000 force plate. The range of movement and mean velocity of both was observed, correlating them with Pearson correlation test. The correlation power was determined by Malina criterion and the significance level adopted for all the tests used a p-value of 0,05. The correlation between center of mass and respective center of pressure variables (range of movement and velocity) are all strong and significant (p < 0,05). The correlations increase their power and significance when observed in closed eyes condition. It can be concluded that, in young adults static balance, either center of pressure or center of mass calculated by kinematic methods are representative.

ABSTRACT
BACKGROUND: Smoking greatly increases the risk of cancer, cardiovascular diseases and osteoporosis. Besides direct harm from smoking, some dietary pattern of smokers have been reported to increase such risk. This study aimed to analyze various nutrients by smoking status, and to find out whether smokers maintain harmful dietary patterns. METHODS: One thousand and six hundred fourteen men were selected who visited the health promotion center of an university hospital in Seoul. The inclusion criteria was the completion of dietary survey. Dietary analysis was done by calculation of amounts of each nutrients from 24-hour recall method. We compared total intake of each nutrients and total calories by smoking status with analysis of variance (ANOVA). Then we adjusted the results for exercise and education level by ANCOVA (analysis of covariance). RESULTS: The study subjects were 840 current smokers (52.0%), 479 ex-smokers (29.7%) and 295 non-smokers (18.3%). The consumption of total fat and cholesterol was significantly high in smokers than non-smokers (P=0.012, P=0.005). The alcohol intake was higher in smokers and ex-smokers than non-smokers (P <0.001, P=0.007). The smokers and ex-smokers had less calcium than non- smokers (P=0.001, P=0.044). Furthermore, the smokers exercised less than ex-smokers and non-smokers (P <0.001). CONCLUSIONS: The smokers consumed more total fat and cholesterol which increases the risk of cardiovascular diseases. They also had less calcium and drank more alcohol. Comprehensive approach which includes intervention for dietary intakes in addition to smoking cessation is desirable to decrease health risk for smokers.
