UNASSIGNED: This case-control study collected data from December 2018 to December 2019 on 1522 preschool children in Urumqi (779 boys and 743 girls) who were diagnosed with pneumonia by a physician. A control group of children who had never had pneumonia was matched in a 1:1 ratio based on gender, age, and ethnicity. Using questionnaires, data were collected on children\'s general characteristics, passive smoking, types of housing, flooring materials, and indoor dampness, analyzing potential factors associated with the incidence of pediatric pneumonia.
UNASSIGNED: Multivariate analysis revealed that cesarean birth (odds ratio [OR] = 1.27; 95 % confidence interval [95%CI] = 1.08-1.48), being an only child (OR = 1.32; 95%CI = 1.13-1.55), antibiotic treatment during the first year of life (OR = 2.51; 95%CI = 1.98-3.19), passive smoking during the mother\'s pregnancy (OR = 1.62; 95%CI = 1.24-2.13), living in multi-family apartment housing (OR = 1.64; 95%CI = 1.28-2.10) and other types of housing (OR = 1.47; 95%CI = 1.09-1.99), laminate flooring (OR = 1.31; 95%CI = 1.01-1.72), and tile/stone/cement flooring flooring (OR = 1.31; 95%CI = 1.06-1.61), and dampness in dwelling (during first year of mother\'s pregnancy) (OR = 1.30; 95%CI = 1.04-1.63) were risk factors for pediatric pneumonia. The use of fresh air filtration systems in children\'s residences (OR = 0.66; 95%CI = 0.50-0.86) was identified as a protective factor.
UNASSIGNED: This study underscores the importance of indoor environmental factors in the prevention of pediatric pneumonia. Public health strategies should consider these factors to reduce the incidence of pneumonia in children. Future research needs to be conducted over a broader geographical range and consider a more comprehensive range of factors influencing pediatric pneumonia.
■本病例对照研究收集了2018年12月至2019年12月乌鲁木齐1522名学龄前儿童(779名男孩和743名女孩)经医生诊断为肺炎的数据。对照组从未患过肺炎的儿童根据性别以1:1的比例匹配,年龄,和种族。使用问卷,收集了关于儿童一般特征的数据,被动吸烟,住房类型,地板材料,室内潮湿,分析与小儿肺炎发病相关的潜在因素。
■多变量分析显示剖宫产(比值比[OR]=1.27;95%置信区间[95CI]=1.08-1.48),作为独生子女(OR=1.32;95CI=1.13-1.55),生命第一年的抗生素治疗(OR=2.51;95CI=1.98-3.19),母亲怀孕期间被动吸烟(OR=1.62;95CI=1.24-2.13),住在多户公寓住房(OR=1.64;95CI=1.28-2.10)和其他类型的住房(OR=1.47;95CI=1.09-1.99),复合地板(OR=1.31;95CI=1.01-1.72),和瓷砖/石材/水泥地板(OR=1.31;95CI=1.06-1.61),和潮湿(母亲怀孕第一年)(OR=1.30;95CI=1.04-1.63)是小儿肺炎的危险因素。在儿童住宅中使用新鲜空气过滤系统(OR=0.66;95CI=0.50-0.86)被确定为保护因素。
■本研究强调了室内环境因素对预防小儿肺炎的重要性。公共卫生策略应考虑这些因素,以减少儿童肺炎的发生率。未来的研究需要在更广泛的地理范围内进行,并考虑更全面的影响小儿肺炎的因素。
