The purpose of this study was to assess the role of siblings in day care as a determinant of infants' risk of lower respiratory tract infections.
A total of 3238 children (86%) out of 3754 Oslo, Norway, newborns recruited in 1992/93 were followed for 1 year.
In logistic regression analysis, the risk of infection was increased in (1) infants with one or more siblings compared with infants without siblings (adjusted odds ratio [OR] = 2.3; 95% confidence interval [CI] = 1.84, 2.85) and (2) infants with one or more siblings in day care compared with infants with siblings not in day care (adjusted OR = 1.7; 95% CI = 1.21, 2.26).
The results suggest that siblings in day care outside the home increase infants' risk of lower respiratory tract infections.
本研究旨在评估兄弟姐妹在日托机构中作为婴儿下呼吸道感染风险决定因素的作用。
对1992/93年在挪威奥斯陆招募的3754名新生儿中的3238名儿童(86%)进行了为期1年的随访。
在逻辑回归分析中,与无兄弟姐妹的婴儿相比,(1)有一个或多个兄弟姐妹的婴儿感染风险增加(调整后的优势比[OR]=2.3;95%置信区间[CI]=1.84,2.85);与兄弟姐妹不在日托机构的婴儿相比,(2)有一个或多个兄弟姐妹在日托机构的婴儿感染风险增加(调整后的OR=1.7;95%CI=1.21,2.26)。
结果表明,家庭外日托机构中的兄弟姐妹会增加婴儿下呼吸道感染的风险。
