“…Numerous previous studies showed reduced effects of sex (Hackett et al, 1976;Maggiorini et al, 1990;Schneider et al, 2002;Vardy et al, 2006;Wang et al, 2010) and age (Schneider et al, 2002;Vardy et al, 2005;Wang et al, 2010) on AMS, but some studies found a higher risk of AMS in women (Honigman et al, 1993) or men ( Johnson and Rock, 1988), and in younger adults (Hackett et al, 1976;Honigman et al, 1993) or the elderly (Maggiorini et al, 1990). Our results suggest that sex and age differences are of little importance in terms of the prevalence and severity of AMS among climbers of Mt.…”

Moreover, our sample size (n = 2267) was much larger than those typically found in previous epidemiological studies (n = 130-827 participants) (Hackett et al, 1976;Maggiorini et al, 1990;Basnyat et al, 2000;Schneider et al, 2002;Vardy et al, 2005Vardy et al, , 2006Mairer et al, 2009Mairer et al, , 2010, although one previous study had over 3000 participants (Honigman et al, 1993).…”

Horiuchi, Masahiro, Tadashi Uno, Junko Endo, Yoko Handa, and Tatsuya Hasegawa. Impact of sleeping altitude on symptoms of acute mountain sickness on Mt. Fuji. High Alt Med Biol. 19:193-200, 2018. Aims: We sought to investigate the factors influencing acute mountain sickness (AMS) on Mt. Fuji in Japan, in particular, to assess the effects of sleeping altitude, by means of a questionnaire survey. This study involved 1932 participants who climbed Mt. Fuji, and obtained information regarding sex, age, and whether participants stayed at the mountain lodges. The AMS survey excluded the perceived sleep difficulties assessed with the Lake Louise Scoring (LLS) system for all climbers. Results: The overall prevalence of AMS was 31.6% for all participants (LLS score ‡3 with headache, excluding sleep difficulties). A univariate analysis revealed that overnight stay at Mt. Fuji was associated with an increased prevalence of AMS, but that sex and age were not. For overnight lodgers, the mean sleeping altitude in participants with AMS was slightly higher than that in participants without AMS ( p < 0.05). Moreover, participants who stayed above 2870 m were more likely to experience AMS than those who stayed below 2815 m ( p < 0.001), but sex and age were not significantly associated with the probability of experiencing AMS. Conclusions: Staying overnight at a mountain lodge, especially one above 2870 m, may be associated with an increased prevalence of AMS on Mt. Fuji.

“…Preparedness plays a key role in reducing certain risks when trekking at high altitude. A previous study has shown that foreign national trekkers in the Nepal Himalaya who were better prepared, in terms of their understanding of AMS, were more likely to adhere to recommended ascent guidelines and experience fewer altitude-related illnesses (Vardy et al, 2005). However, within our study (which did not assess participants' understanding of AMS), approximately 90% of trekking groups included foreign nationals who had received or read information on altitude illness and acclimatization.…”

This cross-sectional study investigates preparedness and medical problems in Nepalese staff and porters compared with foreign nationals trekking at altitude in the Nepal Himalaya. 331 Nepalese and 338 foreign nationals in 61 trekking groups were surveyed over 4 weeks on the Annapurna trekking circuit. Foreign nationals reported that 92% of trekking groups received altitude illness information and carried a medical kit. However, fewer than 30% knew the evacuation insurance status of the Nepalese staff and porters on their trek, 39% would not pay for an ill Nepalese national's helicopter evacuation, and 41% reported insufficient resources to carry an individual. Medical problems occurred in 44% of groups. A significantly higher proportion of Nepalese staff and porters were evacuated compared with foreign nationals. No significant differences in Nepalese and foreign national preparation were found between groups with and without medical problems. Medical problems were commonly encountered, yet many groups lacked resources to evacuate someone dangerously ill. Foreign and Nepalese nationals have a duty of care towards each other; recognizing that preparedness relies not only on a first aid kit, but also on knowledge of acclimatization and individuals' insurance is an important part of health and safety for individuals trekking at altitude.

“…For example, athletes may train at high altitudes, which can result in erythrocytosis. Some studies suggest that a high–low method of sleeping at high altitude followed by training at low altitude is a better training strategy than training or sleeping at either high or low altitudes alone 54. Some athletes have tried sleeping at simulated high altitude by using low oxygen tents.…”

Drug abuse occurs in all sports and at most levels of competition. Athletic life may lead to drug abuse for a number of reasons, including for performance enhancement, to self-treat otherwise untreated mental illness, and to deal with stressors, such as pressure to perform, injuries, physical pain, and retirement from sport. This review examines the history of doping in athletes, the effects of different classes of substances used for doping, side effects of doping, the role of anti-doping organizations, and treatment of affected athletes. Doping goes back to ancient times, prior to the development of organized sports. Performance-enhancing drugs have continued to evolve, with “advances” in doping strategies driven by improved drug testing detection methods and advances in scientific research that can lead to the discovery and use of substances that may later be banned. Many sports organizations have come to ban the use of performance-enhancing drugs and have very strict consequences for people caught using them. There is variable evidence for the performance-enhancing effects and side effects of the various substances that are used for doping. Drug abuse in athletes should be addressed with preventive measures, education, motivational interviewing, and, when indicated, pharmacologic interventions.
