Objective To analyze the epidemiological characteristics and associated factors of delayed voiding among middle school students, and to provide the basis for health education.
Methods A total of 1 260 middle school students were selected from Sanmen country in Taizhou by using multi-stage stratified sampling method. A cross-sectional survey was conducted to investigate the demographic characteristics, epidemiological characteristics and associated factors of delayed voiding by questionnaire.
Results The proportion of frequent delayed voiding among middle school students was 14.37% (181). The proportion among senior high school students was 15.51% (90), and among junior high school students was 13.67% (91), no significant differences were found by grade (χ 2 = 0.57, P = 0.45). The multivariate Logistic regression analysis showed that residential school, homework per day >2 hours, games and reduce the frequency of drinking ≥7 times/week were risk factors for delayed voiding frequently in junior high school students ( OR = 3.71, 1.70, 3.02, 6.52, P<0.05). Higher than 2 hours of daily homework, a supportive or indifferent attitude to delayed voiding, staying in bed after waking up, drinking <0.5 L/d or ≥ 2.0 L/d, and reduce the frequency of drinking ≥7 times/week were risk factors for delayed voiding behavior in high school students ( OR = 2.23, 1.81, 2.22, 3.48, 2.69, 3.00, P< 0.05).
Conclusion The prevalence of frequent delayed voiding was high among middle school students. Attitude, environment and the quality of drinking water were the primary factors of frequent delayed voiding.
【摘要】 目的 了解中学生强制性尿潴留行为流行特征及影响因素, 为开展相关的健康干预提供参考依据。 方法 采用多阶段分层整群随机抽样方法, 在台州三门县抽取 1 260 名中学生。通过问卷调査法收集人口社会学特征、强制性尿 潴留行为现状和影响因素等信息。 结果 中学生过去半年经常强制性尿潴留行为的报告率为 14.37% (181 名), 初中生为 13.67% (91 名), 髙中生为 15.51% (90 名) , 学段间差异无统计学意义 (χ 2 = 0.57, P =0.45)。多因素 Logistic 回归分析发现, 住校、每天完成课外作业时间 >2 h、玩游戏和每周减少喝水 ≥7 次与初中生经常强制性尿潴留行为呈正相关 ( OR 值分别为 3.71, 1.70, 3.02和6.52, P 值均<0.05)；每天完成课外作业时间 >2 h、对强制性尿潴留持不抵制态度、睡醒后赖床不起、饮水 量 ≥2 L/d 或 <0.5 L/d、为了避免上课排尿减少喝水 ≥7 次/周与髙中生强制性尿潴留行为发生呈正相关 ( OR 值分别为 2.23, 1.81, 2.22, 3.48, 2.69, 3.00, P 值均<0.05)。 结论 中学生强制性尿潴留不良排尿行为较为普遍。态度、环境和饮水情 况是中学生强制性尿潴留的主要影响因素。
