Abstract:
Objective:To find out the prevalence and risk factors of Atopic Dermatitis(AD) of children under 1 year old in Shihua area ,Jinshan District ,Shanghal .Methods:Neonatal general conditions at birth were collected in Jinshan Hospital , Fudan University from September 2012 to August 2013 ,while questionnalre survey was conducted to understand the correlative factors .Follow‐up was done at 1 ,2 ,6 ,9 ,12 month‐old so as to understand the incidence of AD and the conditions about feeding and growth .Results:There were 2426 newborns were selected ,and 915 were followed‐up .There were 271 AD patients ,and the prevalence rate is 29 .6% .Prevalence rate of AD was 29 .9%‐37 .6% in newborns who were born in March , April ,May ,July ,August and September ,which was higher than those in other months(20 .7%‐24 .2% ) .Univariate analysis showed that the prevalence of AD was significantly correlated with parents’ allergies and increase of the eosinophil count in infant blood (P<0 .01) .It was also correlated with boy ,caesarean section ,artificial feeding or mixed feeding ,mother’s high level of education of mothers ,passive smoking ,and there were significant differences (P< 0 .05) .However ,it was not correlated with the mother’s prenatal history of infection (P>0 .05) .Multivariate logistic regression analysis showed that AD prevalence rate was significantly correlated to mother’s high level of education ,increase of eosinophil count in infant blood(P<0 .01) .It was also correlated to caesarean section ,artificial feeding or mixed feeding ,parental allergy history ,and there were significant differences(P< 0 .05) .Conclusions:The prevalence rate of infant AD in Jinshan District of Shanghal City was 29 .6% .The incidence of AD had seasonal trends .Infants ,who were born in the spring and summer ,had higher prevalence rates of AD .Parents with allergies ,mother’s high level of education ,artificial feeding or mixed feeding after birth ,caesarean section and increase of eosinophil count in infant blood are risk factors for infant AD .
