Study On Influencing Factors Of Recurrent Respiratory Tract Infections In Children And Its Correlation With TCM Syndrome Types

Objective: By observing and recording the distribution of influencing factors,TCM syndrome types and constitution of children with recurrent respiratory tract infections aged 2~5 years old in Kunming area,the influence of influencing factors on the onset of the disease and the correlation with TCM syndrome types are discussed.In order to provide objective basis and reference for improving the accuracy of clinical syndrome differentiation of children with recurrent respiratory tract infections in Kunming area and preventing and treating the disease from various influencing factors.Methods: Formulate a situation questionnaire,syndrome record form and constitution classification and judgment form,include children aged 2~5 who meet the western medicine diagnostic criteria for recurrent respiratory tract infections and live in Kunming area,record the syndrome,signs and general conditions of children,and analyze the influencing factors,TCM syndrome types and constitution distribution of children with recurrent respiratory tract infections in Kunming area through statistical processing,and the influence of influencing factors on the onset of the disease and the correlation with syndrome types.Results: A total of 164 cases with complete information were collected in this study.The basic information is as follows:1.General distribution:(1)Gender distribution: 89 cases(54.3%)were boys and75 cases(45.7%)were girls;(2)Age distribution: 72 children aged 3~4(43.9%),59 children aged 4~5(36.0%),33 children aged 2~3(20.1%);(3)distribution of disease course: 92 cases(56.1%)with disease course > 3 years,72 cases(43.9%)with disease course ? 3 years;(4)Seasonal distribution of diseases: 51 cases(31.1%)in autumn,42 cases(25.6%)in winter,31 cases(18.9%)in spring,26 cases(15.9%)in summer,and 14 cases(8.5%)all year round.2.Distribution of other influencing factors of children's recurrent respiratory tract infections:(1)Distribution of feeding history: 97 cases(59.5%)were non-breast-fed,including 59 cases(36.0%)of artificial feeding and 38 cases(23.2%)of mixed feeding;67 cases(40.8%)were breast fed.(2)Distribution of dietary habits:83 cases(50.6%)were addicted to dryness-heat,53 cases(32.3%)to cold,and 28cases(17.1%)to moderate diet.(3)Nutrient supplement distribution: 90 cases(54.9%)were not supplemented with nutrients;74 cases(45.1%)were supplemented with nutrition,of which 14.6%,6.7% and 6.1% were supplemented with vitamin D,calcium and vitamin D calcium respectively.(4)distribution of outdoor activities: 113cases(68.9%)were < 2h/day,51 cases(31.1%)were ? 2h/day;(5)Distribution of antibiotic use and passive smoking: 99 cases(60.4%)took antibiotics for ? 30days/year,115 cases(70.1%)had passive smoking.3.Physical distribution of children with recurrent respiratory tract infections: 153cases(93.3%)had single physical constitution and 11 cases(6.7%)had compound physical constitution.In single constitution,57 cases(37.3%)were of qi deficiency,35 cases(22.9%)were of excess heat,25 cases(16.3%)were of yin deficiency,18cases(11.8%)were of mild nature,13 cases(8.5%)were of phlegm-dampness nature,and 5 cases(3.3%)were of special nature.In the compound constitution,6 cases(54.5%)were qi deficiency + yin deficiency,3 cases(27.3%)were qi deficiency +phlegm dampness,and 2 cases(18.2%)were qi deficiency + special nature.4.Distribution of TCM syndromes in children with recurrent respiratory tract infection: 63 cases(38.4%)of lung-spleen qi deficiency syndrome,38 cases(23.2%)of lung-stomach excess heat syndrome,30 cases(18.3%)of qi-yin deficiency syndrome,19 cases(11.6%)of Ying-Wei imbalance syndrome,and 14 cases(8.5%)of spleen-kidney deficiency syndrome.5.The relationship between influencing factors and TCM syndromes: through statistical analysis,the course of disease,the season of disease onset,dietary habits and physical factors are correlated with TCM syndromes(p < 0.05);Sex,age group,mode of delivery,birth condition,birth weight,feeding history,outdoor activities,previous illness history of the child,antibiotic use,passive smoking and disease type were not correlated with TCM syndrome type(P > 0.05).Conclusion:In this study:1.There is no significant gender difference in the incidence of recurrent respiratory tract infections among children aged 2~5 years old in Kunming area;The onset age was 3~4 years old.The main course of disease is > 3 years.Disease-prone seasons are usually found in autumn and winter.Non-breast-feeding is common.The eating habits are mostly addicted to dryness-heat.Most outdoor activities are < 2h/day;Most of the children took antibiotics for ? 30 days/year and had passive smoking.2.Common types of recurrent respiratory tract infections in children are deficiency of lung and spleen qi and excess heat of lung and stomach.Its constitution is common in qi deficiency and excess heat.3.The course of children's recurrent respiratory tract infections,the season of disease onset,eating habits,constitution and TCM syndrome types are all correlated,suggesting that the above-mentioned influencing factors can affect the distribution of TCM syndrome types,and also confirm that the differentiation and treatment of this disease must be based on climate,environment and constitution.
