Abstract:Objective To investigate the disease spectrum of hospitalized soldiers in the Tibetan region and provide data for disease prevention in plateau mountain areas.Methods The inpatients from the armed police forces who had been treated at our hospital between November 1, 2013 and May 31, 2016 were selected and classified according to the ICD-10. Their medical records were analyzed.Results 611 cases were collected with a mean age of 22.74 years old. About 244 soldierss were admitted each year. The top five systemic diseases were associated with the digestive system (23.7%), musculoskeletal and connective tissue (12.6%), skin and subcutaneous tissue (10.8%), injury and poisoning (10.6%), and respiratory system (9.0%). The top five diseases were gastroenteritis and tonsillitis (6.2%), protrusion of the intervertebral disc (4.9%), upper respiratory tract infection (4.7%), appendicitis (4.4%), and hemorrhoids (3.9%). In autumn, the incidence of musculoskeletal and connective tissue diseases was the highest, but in other seasons digestive system diseases were the most prevalent. Injuries during military training accounted for 19.3%.Conclusion Diseases related to the digestive system, musculoskeletal and connective tissue, skin and subcutaneous tissue, injury and poisoning, and the respiratory system should be the focus of attention at Tibetan mountain hospitals for armed police forces. Targeted prevention measures should be recommended based on the spectral characteristics of different populations and seasons.
