ABSTRACT
To identify and compare risk factors for recurrent respiratory infections in preschool children between resident and floating population in Yiwu, China. Investigations was conducted in resident and floating population in Yiwu city, Zhejiang province. A structured questionnaire was used to collect information on influence factors. Univariate and multivariate analyses were carried out using the Binary logistic regression. The study was conducted in Yiwu from June 2009 to September 2010. We recruited 844 participants, resident population 639[75.7%] and floating population 205[24.3%] who were preschool children. Multivariate analysis showed that Childbearing age [OR=0.93, 95%CI: 0.88-0.99], Asthma [OR=3.20, 95%CI: 1.60-6.45], Rickets [OR=5.30, 95%CI: 1.99-14.09], Food preference [OR=1.57, 95%CI: 1.02-2.43], Snack [OR=1.50, 95%CI: 1.07-2.07] were the influence factors for recurrent respiratory infections in resident preschool children. Infant feeding [OR=2.24, 95%CI: 1.31-3.81], Snack [OR=2.06, 95%CI: 1.07-3.98,], Trip mode [OR=2.77, 95%CI: 1.11-6.94] were the influence factors for recurrent respiratory infections in floating preschool children. Public health measures against risk factors should be taken to protect against recurrent respiratory infections in resident and floating preschool children respectively
ABSTRACT
<p><b>OBJECTIVE</b>To study the audiological characteristics of newborns and infants who failed hearing screening.</p><p><b>METHODS</b>One hundred and six infants failed hearing screening received follow-up study with routine audiological evaluations (auditory brainstem response, distortion product otoacoustic emission, tympanometry and visual reinforcement audiometry).</p><p><b>RESULTS</b>Sixty-five infants (61.3%) of this group were normal hearing subjects and 39(36. 8% ) of the infants had hearing loss. Two cases (1.9%) received follow-up by phone. Fifteen cases (14.2%) with conductive hearing loss and 24 cases (22.6%) with sensorineural hearing loss. Thirteen (12.3%), 14 (13.2%), 6 (5.7%), and 6 (5.7%) cases were found to be mild, moderate, severe and profound hearing loss respectively. Diagnosis of hearing loss in the thirty-nine infants conducted a prevalence of 0.264% (39/14 785) of congenital hearing loss (both binaural and monaural). The hearing level of those cases with severe and profound hearing loss basically did not change, but that of cases with mild and moderate hearing loss changed.</p><p><b>CONCLUSIONS</b>Early identification and intervention of infants with severe and profound hearing loss by 6 months of age were successful. Infants with mild and moderate hearing loss should be followed up to six or eight months and received routine audiologic evaluations.</p>
