Abstract:
Objective To understand the epidemiological characteristics and influencing factors of Mycoplasma pneumoniae (MP) infection in children with respiratory tract infection in Yangzhou , and provide theoretical guidance for the prevention of this disease. Methods Pharyngeal swab sample was collected from Children of 21 403 in the Respiratory Infection Outpatient Department of Subei People's Hospital in Jiangsu Province from January 2022 to December 2023,and fluorescence quantitative polymerase chain reaction (PCR) was used to detect MP-DNA in samples to analyze the detection of MP . A self-made questionnaire was used to collect information on children's hand hygiene, family dietary habits, indoor air conditioning usage, and outdoor exercise. Binary logistic regression was used to analyze the influencing factors of Mycoplasma pneumoniae infection in children. Results The overall infection rate of Mycoplasma pneumoniae in resident children aged 0-14 in Yangzhou from 2022 to 2023 was 32.04%（6 857/21 403）. There was an age difference in the positive rate of Mycoplasma pneumoniae in children, with a higher incidence in the 7-14 years old ( P < 0.001) . There were differences in the infection rate of Mycoplasma pneumoniae in children with different BMI, geographical location, exercise intensity , frequency of using air conditioning ventilation mode, frequency of washing hands before and after meals, frequency of daily drinks、sweets or snacks, and frequency of brushing teeth per day ( P < 0.05 ) .The logistic regression results showed that age between 1-3 years old , BMI ≥ 24 , and never washing hands before and after meals were independent influencing factors for Mycoplasma pneumoniae infection in children ; monthly cumulative precipitation , PM2.5 , and O3 increase the risk of Mycoplasma pneumoniae infection in children , while PM10 reduces the risk of Mycoplasma pneumoniae infection in children. Conclusion The positive rate of Mycoplasma pneumoniae in 7-14 year old children in Yangzhou is relatively high. BMI, never washing hands before and after meals, and meteorological factors are closely related to Mycoplasma pneumoniae infection.
