Acute mountain sickness and ascent rates in trekkers above 2500 m in the Nepali Himalaya.

Introduction: The aim of this study was to ascertain the incidence of acute mountain sickness (AMS) at different altitudes in the Solu-Khumbu. This was a pilot to examine the feasibility of investigating demographic, behavioral, and physiological factors related to the etiology of AMS and to assess the region's suitability for a future study.

Methods: A convenience sample of 150 recreational trekkers staying in teahouses was interviewed at altitudes above 2500 m.

Can knowledge protect against acute mountain sickness?

Background: Studies show that the well-prepared traveller is less likely to suffer travel related illness. This study is designed to examine trekkers' knowledge of altitude sickness in an attempt to see whether knowledge can protect against acute mountain sickness (AMS) and high altitude pulmonary or cerebral oedema (HAPE/HACE).

Methods: A convenience sample of 130 trekkers were interviewed in the Solu Khumbu region of Nepal.
