The accuracy of a long aiming movement was studied as a function of whether it was performed toward or away from the midline of the subject's body in the presence or absence of visual feedback. 30 right-handed, male university students (19—26 yr.) served as subjects. With movement distance and duration controlled, the mean percentage of error was 6 34% less for movements made toward the body's midline than for those performed away from the midline. The mean percentage of error was also 48% less in the presence of visual feedback than in its absence. However, contrary to our expectation, movements executed toward the body's midline were not appreciably less disrupted in the absence of visual feedback than movements performed away from the midline.

Scarce studies described eating habits and diet quality among university students in Lebanon. The aim of this study is to assess the rate of adherence to the Mediterranean diet (MedDiet) among Lebanese university students. A cross-sectional nutritional survey was carried out on 525 students (53% men, 18–25 years old) from the University of Balamand, Lebanon. Adherence to the MedDiet was assessed using a validated 14-item MedDiet adherence score. Mean adherence to the MedDiet was 7.96 (standard deviation 2.2), and it was adequate in 59% of participants. Adherence to the MedDiet was higher in older students and nonsmokers. Legumes, vegetables, fruits, and nuts were consumed according to the MedDiet standards among a minimum of 48.4% and a maximum of 69.5% of participants. Chicken, turkey, or rabbit was preferred by 66.9% of participants instead of beef, pork, hamburgers, or sausages; however, just 56.2% of participants showed adequate intake of red meat, hamburger, or meat products. Only 28.8% of them referred to an adequate intake of fish or shellfish. Most of the participants (86.3%) used olive oil as the main added fat, and 67.2% reported a low intake of butter and derivatives. Sofrito was also very usual among participants (79.6%). Only half of the studied sample reported an adequate intake of sweet or carbonated beverages and commercial sweets or pastries. Among the assessed sample, half the participants showed adequate adherence to the MedDiet; however, the mean of adherence among the sample is low.

Background In Australia, 15- to 29-year-olds account for 75% of all sexually transmissible infection (STI) diagnoses. STI rates among young men are rising, with most diagnosed in general practice. Young men less frequently attend general practice than young women, and rarely present with sexual health issues, making it difficult for general practitioners (GPs) to offer opportunistic STI education and screening. Little is known of the barriers preventing male university students accessing general practice for sexual health care, or what would facilitate this. Methods: Semi-structured interviews were conducted with young men aged 18–24 years attending university between 2012 and 2014. Interviews were recorded, transcribed and analysed using content and thematic analysis. Results: Twenty-eight interviews of 26–50 min duration found self-imposed views of masculinity, privacy and embarrassment as key barriers to accessing GPs for sexual health care. This was compounded by poor STI knowledge and not knowing when or where to go for care. Participants, except if they were international students, acknowledged school as an important source of sexual health education. The need for sexual health education at university was identified. While the Internet was a popular source, there were mixed views on the benefits of social media and text messaging for sexual health promotion. Conclusions: Current expectations of young male university students to seek sexual health care or acquire sexual health information from medical care may be misplaced. Universities have an excellent opportunity to provide young men with appropriate sexual health information and could offer novel strategies to help young men look after their sexual health.

Abstract OBJECTIVE To understand the meanings that male university students assign to the condition of users of alcohol and other drugs. METHOD An exploratory study using a qualitative approach, with inductive analysis of the content of semi-structured interviews applied to 20 male university students from a public university in the southeast region of Brazil, grounded on the theoretical-methodological referential of interpretive anthropology and ethnographic method. RESULTS Data were construed using content inductive analysis for two topics: use of alcohol and/or drugs as an outlet; and use of alcohol and/or other drugs: an alternative for belonging and identity. CONCLUSION Male university students share the rules of their sociocultural environment that values the use of alcohol and/or other drugs as a way of dealing with the demands and stress ensuing from the everyday university life, and to build identity and belong to this social context, reinforcing the influence of culture.

Abstract Background: The coronavirus disease 2019 (COVID-19) pandemic has changed our daily life. Owing to the imposed restrictions, many educational facilities have introduced remote teaching. This study aims to understand the impact of remote teaching on Japanese university students' sleeping habits.Methods: The participants were medical university students. We used data from an ongoing longitudinal sleeping habits survey. For 684 participants who enrolled in the university during 2018–2020, multilevel analyses of sleep duration during weekdays and weekends across 3 years were conducted, adjusting for gender, grade, place of stay, sleep problems and lifestyle habits. Results: Among the participants, 356 male (mean ± standard deviation: 22 ± 3, 18–37 years old) and 288 female (22 ± 3, 18–32 years old) students in 2018, 365 male (24 ± 3,18–36 years old) and 284 female (22 ± 2, 18–33 years old) students in 2019, and 226 male (20 ± 3,18-36 years old) and 167 female (21 ± 2, 18–34 years old) students in 2020 answered the questionnaire. The mean sleep duration during weekdays (in minutes) was 407.6 ± 60.3 in 2018, 406.9 ± 63.0 in 2019, and 417.3 ± 80.9 in 2020. The mean sleep duration during weekends (in minutes) was 494.5 ± 82.5 in 2018, 488.3 ± 87.9 in 2019, and 462.3 ± 96.4 in 2020. The analysis showed that sleep duration during weekdays was associated with the place of stay and survey year. Moreover, students reported significantly longer sleep duration during weekdays in 2020 than 2019, but no significant difference in sleep duration between 2018 and 2019. Sleep duration during weekends was found to be associated with the survey year, gender and always doing something before going to bed. Sleep duration during weekends was shorter in 2020 than 2019 and longer in male students and students who always do something before going to bed. Ten students were reported to have a delayed sleep phase in 2020. Conclusions: Students' sleep duration increased during weekdays and decreased during weekends in 2020. This difference could be explained by the COVID-19 pandemic and the introduction of remote teaching.

Aim. The article deals with establishing the effect of step aerobics and artistic gymnastics on physical performance in first year female university students. Materials and methods. 80 full-time female university students participated in the study. The first group practiced artistic gymnastics (Group 1, n = 40), the second group (Group 2, n = 40) – step aerobics. The mean age was 18.35 ± 0.04 years. In September and December 2017, their physical development, physical fitness, physical performance, respiratory and cardiovascular systems were assessed based on standard procedures using the data of maximum oxygen consumption and the step test. Results. At the beginning of the experiments, there were no statistically significant differences between Group 1 and Group 2. The mean maximum oxygen consumption values corresponded to satisfactory performance (39.85 ± 0.37 – Group 1, 38.92 ± 0.42 – Group 2, р = 0.1). At the end of the experiment, there were statistically significant differences in terms of the mean maximum oxygen consumption: 40.73 ± 0.21 – Group 1 and 41.61 ± 0.21 – Group 2. The results of the ranking showed that the majority of participants demonstrated an increase in physical performance. Group 1 showed an increase in the standing long jump, Group 2 improved 2000 m running time and the standing long jump. Group 2 also demonstrated a decrease in heart rate and an increase in adaptation capacities. Conclusion. The lessons of artistic gymnastics during a semester do not influence significantly physical performance but improve speed-strength characteristics. Step aerobics influences positively physical performance, speed-strength characteristics, and the cardio­vascular system in first-year female university students not related to sport.

Early diagnosis of breast cancer is the best approach towards its control that may result in alleviating related mortality and morbidity. This study aimed to evaluate knowledge about breast cancer and both practices and perceived barriers to breast self-examination among female university students in Bangladesh. A cross-sectional study was carried out with 400 female students of Jahangirnagar University, Bangladesh. Participants were sampled from female dormitories at the university from January to April 2020. Proportionate stratified random sampling was conducted to calculate the study sample from each dormitory. A pre-tested, semi-structured self-reported questionnaire was employed to collect data from participants during the survey periods. The questionnaire consists of demographic variables, items about knowledge about breast cancer, breast self-examination practices and its barriers. We applied descriptive and inferential statistics, and data were analyzed using SPSS. Participants aged between 18-26 years and comprised university students of 1st year (20%), 2nd year (24%), 3rd year (22%), 4th year (21%) and Masters (14.%). 18% of them had reported positive family history (mother, aunt, sister/cousin, grandmother) of breast cancer. The overall mean score of total knowledge items was 15 (SD = 3) out of 43, with an overall correct rate of 34%. The mean score of total knowledge items was significantly higher (p<0.001) among Masters students and students with family members who have breast cancer. Only one in five students (21%) ever practiced breast self-examination. The mean score of practice towards breast self-examination was significantly higher (p<0.001) among participants who reported having family member of breast cancer. It is noted that the total knowledge score about breast cancer and practice towards breast self-examination are significantly correlated with each other (r = 0.54; p<0.001). About 33% participants had reported that lack of knowledge as the main barrier to practicing breast self-examination followed by I do not have the symptoms (22%), and shyness/ uncomfortable feelings (17%). The study revealed low levels of knowledge about breast cancer and low breast self-examination practices. This implies the need of promotion and implementation of educational interventions programs that are social and culturally appropriate and suitable for specific age groups.
