Objective To investigate the relationship between chronic pharyngitis and lifestyle and obesity. Methods A total of 7 655 participants who underwent a health examination in the Navy General Hospital were recruited. These participants came from the same region and had similar occupations. Their lifestyle information data including smoking status, drinking status, and physical activity were collected. Differences of lifestyle and the prevalence of chronic pharyngitis were compared between men and women. Single-factor analysis and multivariate Logistic regression analysis were performed to identify the relationship of chronic pharyngitis and lifestyle and obesity. Results The proportion of smoking and drinking, the prevalence of chronic pharyngitis, levels of systolic blood pressure, diastolic blood pressure, triglycerides, and fasting blood glucose were significantly higher, and the ratio of lack of exercise and normal body weight significantly decreased, in men than those in women (P<0.01). There were no significant differences in age and LDL-C between different gender groups. The prevalence of chronic pharyngitis increased with the frequency of drinking and the increase of obesity in man and women. The prevalence of chronic pharyngitis was not statistically significant in man with smoking than that in man without smoking. There was no significant difference in the prevalence of chronic pharyngitis between females with or without smoking. The prevalence of chronic pharyngitis decreased with the increase of physical activity in both men and women (P<0.01). Higher levels of systolic blood pressure and fasting blood pressure and regular physical activity were protective factors, and obesity was a harmful factor of chronic pharyngitis in men and women. Currently, smoking and regular drinking were harmful factors of chronic pharyngitis in men but not in women. Old age and occasional alcohol consumption were risk factors for women. Conclusion There is a significant value of strengthening physical activity and maintaining normal body weight in the prevention and treatment of chronic pharyngitis. It is also important for men to quit smoking and limit drinking in the prevention and treatment of chronic pharyngitis.%目的：探讨慢性咽炎与生活方式和肥胖的关系。方法选取在我院健康体检的、来源于同一地区、职业相近的7655例研究对象，进行包括吸烟、饮酒和运动状况的生活方式问卷调查。比较不同性别之间生活方式和慢性咽炎患病率的差异，采用Logistic回归分析不同性别下生活方式和肥胖与慢性咽炎的关系。结果除年龄和低密度脂蛋白胆固醇在不同性别间差异无统计学意义外，男性较女性吸烟和饮酒的比例、慢性咽炎患病率、收缩压、舒张压、三酰甘油和空腹血糖水平均升高；不运动、体质量正常的比例降低（P＜0.01）。随着饮酒和肥胖程度的增加，女性和男性中慢性咽炎的患病率均呈增加的趋势；男性目前吸烟者的慢性咽炎患病率高于不吸烟者，女性不同吸烟状况下慢性咽炎患病率差异无统计学意义；而随着运动程度的增加，男性和女性慢性咽炎患病率均呈逐渐降低的趋势（P＜0.01）。无论男女，较高收缩压、空腹血糖、较多的运动量为慢性咽炎的保护因素，肥胖为慢性咽炎的危险因素；目前吸烟和经常饮酒为男性的危险因素，高龄和偶尔饮酒是女性的危险因素。结论在慢性咽炎的预防和治疗管理中，加强身体锻炼、维持体质量正常具有重要意义。对于男性而言，戒烟和限制饮酒在慢性咽炎的防治中也具有潜在意义。
