Logistic Regression Analysis Of Predisposing Factors For Recurrent Respiratory Tract Infections In Children

Objective:To find the influencing factors of recurrent respiratory tract infections(RRTI),we make analysis of predisposing factors of children with RRTI.At the time this work provides clinical significance to prevent RRTI.Methods: Data was collected from inpatients who were admitted in first auxiliary hospital of Dalian Medica l University from June,2014 to June,2015.By taking thorough medical history,total number of 100 children with RRTI were found and their parents were requested to fill the questionna ire given.Similarly 100 children who had no RRTIs their parents were also asked to fill the questionnaire.According to the inclusion and excluding standards,there were 86 cases in a trial group and 92 cases in a control group identified.The main orderly finish the general message questionnaire.The measure-tool was measurement of temperament in 3-7 year old child and self-rating anxiety scale.This was a case-control study,SPSS version17.0 was used for data analyses: the measured data was analysed by t-test,and counting data by X2 test and Kruskal Wallis test for single factor analysis were considered to be statistically significant when P was 0.05 or less(P≤0.05).Single factor results were analysed by Logistic regression,to get the protective or risk factors of RRTI.Results: 1.There were 47 males(54.6%)and 39 females(45.4%)in trial group,whose average age was(3.76±1.19).there were 60 children of age of 3~5years is 60,26 of age5~7years respectively.There were 52(56.5%)males and 40(43.5%)females in a trial group,whose average their age was(4.02±1.43).58 kids of age 3~5years and 34 kids of age 5~7years.There was no statistical difference in sex and age.2.Main orderlies,maternal childbearing age,spontaneous labor,gestational age(premature delivery),allergic constitution,guardian’s anxiety,passive smoking,outdoor activity(>5h/w),masks,average vegetable and fruit(>250g/d),antibiotic usage(>30days/y),temperament type(difficulty)are related to RRTI.3.Spontaneous labor,outside activity(>5h/w)and average vegetable and fruit consumption(>250g/d)are protective factors of RRTI;gestational age(premature delivery),allergic constitution,guardian’s anxiety,passive smoking,antibiotic usage(>30days/y)and temperament type(difficulty)are risk factors of RRTI.Conclusion: 1.Birth condition is relative to RRTI,spontaneous labor is protect factor of RRTI whereas gestational age(premature delivery)is risk factor of RRTI.2.Life environment and life style are related to RRTI,enough outside activity(>5h/w)and average vegetable and fruit(>250g/d)may be protective factors of RRTI.And passive smoking may be risk factor of RRTI 3.Allergic constitution and antibiotic usage(>30days/y)may be risk factors of RRTI.4.Guardian’s anxiety and some temperament type(difficulty)may be risk factors of RRTI.They are possibly the result of each other.
