Maternal dietary and environmental risk factors in children with asthma comorbid neuropsychiatric disorders / 中华实用儿科临床杂志

ABSTRACT

Objective To explore the prenatal dietary and environmental risk factors in children aged 6-16 years with asthma (CWA) comorbid neuropsychiatric disorders.Methods This cross-sectional study was conducted from March 2016 to March 2017.CWA aged 6 to 16 years were recruited as the study participants at the Outpatient Asthma Unit of Guizhou Provincial People's Hospital,China.Informed consent was obtained from their parents,and their parents were invited to participate in the Mini International Neuropsychiatric Interview of children and adolescents (MINI Kid) to assess the current neuropsychiatric disorders.Meanwhile,the questionnaires information about prenatal diet and environment were collected from their mothers as well.Patients were divided into 2 groups,one group with asthma comorbid neuropsychiatric disorders and the other with asthma only.Single factor analysis and multivariate non-conditional Logistic regression analysis were used to determine the risk factors associated with neuropsychiatric comorbidity.Results The study consisted of 261 patients (male163 cases,female98 cases) with asthma,with the age of (11.25 _± 3.12) years,the rate of asthma comorbid neuropsychiatric disorders was 26.4％ (69/261 cases).Single factor analysis showed that prenatal tobacco smoke exposure,winter coal combustion,food additives had statistically significant differences between the 2 group (x2 =7.385,3.993,4.529,all P ＜ 0.05),the other factors were not significantly different between two groups (all P ＞ 0.05);multivariate analysis indicated that prenatal tobacco smoke exposure was the independent risk factor for neuropsychiatric comorbidity in CWA (OR =5.098,95％ CI1.089-23.871,P =0.039).Conclusions The result revealed that the prenatal tobacco smoke exposure is the independent risk factor for neuropsychiatric comorbidity in CWA,need to enhance the propaganda and education of negative effects for parents should be enhanced during pregnancy to diminish the prevalence.
