Abstract Background The maximum oxygen uptake (VO2max) during cardiopulmonary exercise testing (CPET) is considered the best measure of cardiorespiratory fitness. Aim To provide up-to-date reference values for the VO2max per kilogram of body mass (VO2max/kg) obtained by CPET in the Netherlands and Flanders. Methods The Lowlands Fitness Registry contains data from health checks among different professions and was used for this study. Data from 4612 apparently healthy subjects, 3671 males and 941 females, who performed maximum effort during cycle ergometry were analysed. Reference values for the VO2max/kg and corresponding centile curves were created according to the LMS method. Results Age had a negative significant effect (p < .001) and males had higher values of VO2max/kg with an overall difference of 18.0% compared to females. Formulas for reference values were developed: Males: VO2max/kg = − 0.0049 × age2 + 0.0884 × age + 48.263 (R2 = 0.9859; SEE = 1.4364) Females: VO2max/kg = − 0.0021 × age2 − 0.1407 × age + 43.066 (R2 = 0.9989; SEE = 0.5775). Cross-validation showed no relevant statistical mean difference between measured and predicted values for males and a small but significant mean difference for females. We found remarkable higher VO2max/kg values compared to previously published studies. Conclusions This is the first study to provide reference values for the VO2max/kg based on a Dutch/Flemish cohort. Our reference values can be used for a more accurate interpretation of the VO2max in the West-European population.

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.
