| Objective By studying the epidemiological characteristics of osteoarthritis of the knee in plateau troops,we screened out the risk factors of osteoarthritis of the knee in plateau troops,based on which we gave more targeted stepwise treatment for osteoarthritis of the knee in troops in plateau areas,and initially formed a treatment plan for osteoarthritis of the knee in troops in plateau areas,providing a theoretical and applied basis for the clinical treatment of osteoarthritis of the knee in troops in plateau areas of our army.Methods This study is a prospective epidemiological survey study,a group of troops in our western war zone as the study population,the inclusion of the survey subjects are always in the altitude of 2000 m above sea level officers and soldiers,from each station randomly selected troops officers and soldiers 1300 people.1.Design the "knee osteoarthritis epidemiological questionnaire" to randomize the epidemiological survey study by questionnaire to screen out suspected KOA patients.The survey mainly includes: general items: such as name,gender,age,occupation,education level,contact information;onset: such as date of onset,date of consultation,clinical manifestations,imaging examinations,laboratory tests and treatment,etc.2.X-ray examination of officers and soldiers suspected of having KOA to obtain a confirmed patient.Classify the confirmed patients according to X-ray Kellgren-Lawrence classification.3.Data were included in an Excel sheet,a database was established,and data were reviewed and corrected.For statistical analysis,all data were reassigned,and differences were considered statistically significant at the α=0.05 test level,with P<0.05.Variables with significant differences from single-factor analysis were then subjected to multi-factor logistic regression analysis.Results In this study,a total of 1300 copies of the questionnaire "Epidemiological Questionnaire of Osteoarthritis of the Knee" were distributed,and a total of 1234 valid questionnaires were collected,with a pass rate of 94.92%(1234/1300);66 invalid questionnaires were not completed because the basic information was not filled in and the questionnaire content was not filled in.The study subjects were all officers and soldiers stationed in the western plateau region for a long time,and the included study subjects included males,aged 19-53 years old.217 cases(17.59%,217/1234)of suspected osteoarthritis of the knee were found through epidemiological questionnaires,physical examination and subsequent follow-up,and 73 cases were later confirmed by medical units within the military system.In this survey and study,the high-altitude In this study,the prevalence of osteoarthritis was 5.92%(73/1234)among the grassroots officers and soldiers in high altitude areas;the variables that were significant in the univariate analysis were then subjected to multifactor logistic regression analysis,and the results suggested that age,years of service,average annual temperature,training intensity,average daily training hours,and history of knee trauma were risk factors for KOA.Conclusion 1.The prevalence of KOA in basic officers and soldiers at high altitude was 5.92%,and the prevalence tended to increase with age;compared with other epidemiological surveys of KOA at the social level,the prevalence of KOA was higher in basic officers and soldiers at high altitude in the same age group.2.Age,years of service,average annual temperature,training intensity,average daily training hours,and history of knee trauma were the risk factors for KOA in basic officers and soldiers at high altitude.An increase in age by one age(10 years)was associated with a 1.462-fold increase in the likelihood of developing KOA.An increase of one intensity in training intensity increased the likelihood of developing KOA by 0.039 times.3.This study prospectively investigated and studied the prevalence and risk factors of1234 grassroots officers and soldiers in high altitude areas;the results of the appeal examination have important implications for the prevention of KOA in officers and soldiers of troops in high altitude areas,and provide a theoretical basis for future research on the prevention and treatment of KOA and stepped treatment of officers and soldiers in high altitude areas. |
