An Epidemiology Investigation Study On Chronic Pharyngitis And Analyze The Characteristics Of Syndromes Of Guangdong Highway System Employees

Chronic pharyngitis is a diffuse inflammation which occurs in the pharynx mucous membrane, submucous membrane and the lymph system. Viral or bacteria infections can cause chronic pharyngitis. Pathogen can infect the pharynx directly. And chronic pharyngitis be infected by abutting areas such as the nasal cavities, the paranasal sinus or from decayed teeth. The physical simulating factors include excessive smoking and drinking, high temperature particulate matters, and toxic gas etc. Some systemic diseases can cause chronic pharyngitis, for example, anemia, constipation, chronic lower respiratoryitis, and meta blood stasis from cardiovascular diseases.The chronic pharyngitis is a throat familiar and frequently occurring disease with patients condition waving, lingering and difficult to cure. It has a bad influence on work and life of amplitude patients. The epidemiology investigation and the study of distinctive symptom complexes are insufficient at this time. Recently, the causes and treatments of chronic pharyngitis become complicated and intangible because of variations in the environment and the life style and diversifications in occupations. Therefore, it is very important for clinic and epidemiology from comprehensive researches for chronic pharyngitis.Objective:Investigated the epidemiological study on chronic pharyngitis of Guangdong Highway System Employees. To explore the risk factors of chronic pharyngitis and analyze the characteristics of TCM Syndrome so as to provide basis for formulating strategy of cure.Methods:Used the approach of cross-sectional study, adopted the on-the-spot investigation. Throat examination and questionnaire survey 769 Employees in Guangdong Highway System. The study discussed and analyzed the related epidemiology factors of chronic pharyngitis. The study designed an epidemiology questionnaire on chronic pharyngitis 18 questions and TCM Syndrome were in the questionnaire. The comprehensive questions include sexual, age, education level, profession, seniority, diet indulgence, habits and customs, exercise habits, working atmosphere, allergy history, family history, disease history, chronic pharyngitis history and morbidity timing. And the TCM Syndrome epidemiology include course of disease, clinical symptom, physical sign, tongue, pulse manifestation. Multiple Logistic regression models were used to analyze the date about chronic pharyngitis. Gathered the respondent's information material of the four diagnosis methods of the traditional Chinese medicine through doctor interview and carried on different of symptoms and signs according to the relevant syndromes standard of the Chinese traditional medicine. Obtained the information of chronic pharyngitis samples, and analyzed chronic pharyngitis prevalence rate, the related epidemiology factors, syndromes characteristics and card type distribution rule.Results:â‘ This survey was cases with chronic pharyngitis 310 patients. The overall prevalence of chronic pharyngitis was 40.3% in Guangdong Highway System Employees. The prevalence of chronic pharyngitis in male was 48.9% (244 cases), in female was 24.4%(66 cases). There was no significant difference between men and women (x2=43.540 p> 0.05). The prevalence of chronic pharyngitis in outdoor workers was 76.3%(280 cases), and the prevalence in indoor workers was 7.5%(30 cases). The distinction between them was significant difference (x2=377.76 p< 0.01).â‘¡With single factor x2 inspection analysis relative factors and chronic pharyngitis prevalence results showed that occupation, educational level, night shift, working place, working environment, nasal disease and cold situations and the related to chronic pharyngitis (p<0.05), and the age, sex, age, smoking, alcohol consumption, cold food, spicy food, Fried foods, sleep time, adjacent organs and systemic history (nasal disease except), history of allergies, family history and chronic pharyngitis unrelated (p> 0.05). The binary classification Logistic regression analysis was used to analyze the date about chronic pharyngitis. Logistic regression results indicated that the workplace of road and professional, nasal disease were risk factors (OR>1), and working place of authority of management center and flu cases annual were protective factors (OR<1).â‘¢In this study,310 patients with chronic pharyngitis, male 244, female 66 cases; 18 to 35 years 220 cases,78 cases from 36 to 50 years old,51 to 60 years in 12 cases. In the questionnaire on common symptoms of chronic pharyngitis quantify each classification, results show that13 common symptoms of chronic pharyngitis severity (points) from high to low are: continuous dry cough, throat discomfort, Pharyngeal foreign body sensation, pharyngeal adherent viscous sputum, dry throat, throat itching, burning sensation in the throat, swallowing sting, snoring, nausea, retch and phlegm continuous sound, hoarseness.â‘£After the traditional dialectical classification, we know that the lung-kidney syndrome types is the most in TCM Syndrome of chronic pharyngitis. It is 136 cases (43.87%); Secondly for taste weak syndrome types of 81 cases (26.13%). TanNing blood stasis syndrome types is 74 cases (accounted for 23.87%). spleen and kidney Yang syndrome types is 5 patients (1.61%). Other syndrome types is 14 cases (4.52%). The common clinical symptom of TanNing blood stasis syndrome types is most serious. The second serious common clinical symptom is the lung-kidney syndrome types. And the common clinical symptom of kidney Yang syndrome types is the most light. Conclusions:Guangdong Highway system employees' chronic pharyngitis prevalence is in high levels. Population distribution and associated risk factors of chronic pharyngitis have professional characteristics. The incidence of chronic pharyngitis related to professional characters, working environment, personal health state. In TCM Syndrome of chronic pharyngitis, the people of lung-kidney syndrome types is the most and kidney Yang syndrome types is rare. The common clinical symptom of TanNing blood stasis syndrome types is most serious. The second serious common clinical symptom is the lung-kidney syndrome types. And the common clinical symptom of kidney Yang syndrome types is the most light.
