潜艇艇员航海期间发生功能性便秘的影响因素分析

Analysis of influencing factors for functional constipation in submariners during navigation

目的探讨影响潜艇艇员在航海期间发生功能性便秘(FC)的影响因素。方法通过问卷调查分析740名返航潜艇艇员的临床资料。采用χ2检验和Logistic多因素分析模型, 对航海时间、新鲜蔬果供应、饮水量、服役年限、受教育水平、体重指数、晕船情况、运动频次和排便辅助装置等可能影响潜艇艇员航海期间发生FC的因素进行单因素和多因素分析。结果航海时间(χ^(2)=32.704, P<0.001)、新鲜蔬果供应(χ^(2)=6.829, P<0.001)、饮水量(χ^(2)=41.156, P<0.001)、体重指数(χ^(2)=6.858, P=0.009)、运动频次(χ^(2)=17.701, P<0.001)和排便辅助装置(χ^(2)=6.171, P=0.013)是影响潜艇艇员航海期间发生FC的相关因素。Logistic多因素分析显示, 航海时间(OR:0.134, 95%CI:0.069~0.260, P<0.001)、饮水量(OR:0.121, 95%CI:0.060~0.244, P<0.001)、体重指数(OR:0.550, 95%CI:0.384~0.788, P=0.001)、运动频次(OR:0.032, 95%CI:0.012~0.084, P<0.001)以及排便辅助装置(OR:0.580, 95%CI:0.351~0.959, P=0.034)是影响潜艇艇员航海期间发生FC的独立影响因素。结论潜艇艇员在航海期间发生FC可能与航海时间长、饮水量少、体重指数高、缺乏运动以及无排便辅助装置等因素有关。

Objective To investigate the influencing factors of functional constipation(FC)in submariners during navigation.Methods The clinical data of 740 submariners returning from navigation were analyzed by questionnaire.The chi-square(χ2)test and multiple logistic regression analysis were used to conduct univariate and multivariable analyses of factors that may influence the occurrence of FC in submariners during navigation,such as sailing time,fresh fruit and vegetable supply,water intake,years of service,education background,body mass index(BMI),seasickness,exercise frequency,and defecation assistance devices.Results Sailing time(χ^(2)=32.704,P<0.001),fresh fruit and vegetable supply(χ^(2)=6.829,P<0.001),water intake(χ2=41.156,P<0.001),BMI(χ^(2)=6.858,P=0.009),exercise frequency(χ^(2)=17.701,P<0.001),and defecation assistance devices(χ^(2)=6.171,P=0.013)were related factors of the occurrence of FC in submariners during navigation.Multiple logistic regression analysis showed that sailing time(OR:0.134,95%CI:0.069-0.260,P<0.001),water intake(OR:0.121,95%CI:0.060-0.244,P<0.001),BMI(OR:0.550,95%CI:0.384-0.788,P=0.001),exercise frequency(OR:0.032,95%CI:0.012-0.084,P<0.001),and defecation assistance devices(OR:0.580,95%CI:0.351-0.959,P=0.034)were independent risk factors of the occurrence of FC in submariners during navigation.Conclusion The occurrence of FC in submariners during navigation may be related to factors such as long sailing time,low water intake,high BMI,lack of exercise,and no available defecation assistance devices.
