| Objectives: To investigate the status of children’s blood lead exposure,its influencing factors and its influence on children’s psychological behavior in Shenyang,and to provide reference for further targeted preventive measures to reduce children’s blood lead level,reduce the occurrence of children’s psychological behavior problems and promote children’s physical and mental health.Methods: The method of convenient sampling was adopted to select hospitalized children aged 1-6 years(mainly with respiratory tract infection)from a Grade A hospital in Shenyang.With the informed consent of their parents,2ml of fasting venous blood was extracted,and the blood lead level was detected by Tungsten-Zhou atomic absorption spectrometry.The mental and behavioral problems of children aged1-6 were evaluated by the Preschool Children Mental Health Assessment Scale.Statistical analysis was performed using SPSS 22.0.Results: 1.In this study,a total of 273 children aged 1-6 were investigated,and the average blood lead level was 26.68μg/L.The average blood lead was 27.52μg/L in boys and 25.97μg/L in girls,and there were 14 children(5.13%)with blood lead levels ≥50μg/L,no blood lead levels ≥100μg /L children.2.The results of univariate analysis showed that the correlative factor of blood lead level in children was age,whether to wash hands before meals,mother’s occupation,and frequency of eating puffed food(all P values <0.05).Multivariate logistic regression analysis showed that frequent consumption of puffed food was an independent risk factor for elevated blood lead levels in children(OR=11.457,95%CI=3.753-34.980).3.The results of a single factor analysis of children’s psychological and behavioral problems showed that blood lead levels,age,and gender were related to children’s behavioral disorders(P<0.05);the education level of the mother,whether the mother smoked,the education level of the caregiver,and the decoration of the living environment and the character of the child Defect dimension is correlated(P<0.05);vegetable intake frequency <1 time/day is correlated with children’s mood disorders,personality defects,social maladjustment,behavior disorders,communication defects,and other barrier dimensions(P<0.05);multiple linearity Regression analysis results show that:(1)Children’s mood disorders are mainly affected by the frequency of eating puffed food(β=-0.513)and the frequency of eating vegetables(β=-1.436).The higher the frequency of eating puffed food,the lower the frequency of eating vegetables.The higher the emotional disorder score;the personality defects of children are mainly affected by the decoration of the living environment(β=1.668),the frequency of eating vegetables(β=-1.018)and the frequency of eating puffed food(β=-0.768),the decoration of the living environment and the eating of puffed food The higher the frequency and the lower the frequency of eating vegetables,the higher the children’s personality defect scores;children’s social maladaptation is mainly affected by the frequency of eating vegetables(β=-0.009)and the frequency of eating puffed foods(β=-0.874),and the frequency of eating puffed foods The higher the frequency and the lower the frequency of eating vegetables,the higher the children’s social maladjustment score;children’s behavioral disorders are mainly affected by age(β=1.146),gender(β=-0.847),mother’s education level(β=-1.169),and blood lead level(β=-0.027),the frequency of eating vegetables(β=-1.392)and the frequency of eating puffed foods(β=-0.921),the older the age,the female gender,the lower the mother’s education level,the higher the blood lead level,The higher the frequency of eating puffed food and the lower the frequency of eating vegetables,the higher the children’s emotional disorder score;Children’s communication defects are mainly affected by the family’s living standard(β=-0.680),the education level of the supporters(β=-0.632),the frequency of eating vegetables(β=-0.576)and the frequency of eating puffed foods(β=-0.727).The lower the standard of living,the lower the education level of the caregivers,the higher the frequency of eating puffed foods,and the lower the frequency of eating vegetables,the higher the children’s communication defect scores;children’s bad habits are mainly affected by the frequency of eating milk and dairy products(β=-0.689),The influence of the frequency of eating fruits(β=-0.773),the frequency of eating puffed foods(β=-0.709)and the frequency of eating carbonated beverages(β=-0.328),the lower the frequency of eating milk and dairy products,the lower the frequency of eating fruits,and the The higher the frequency of puffed food and the higher the frequency of eating carbonated beverages,the higher the children’s bad habits score;other obstacles in children are mainly affected by the family living standard(β=-0.85),the frequency of eating vegetables(β=-0.719)and the frequency of eating puffed food(β=-0.508),the lower the family living standard,the higher the frequency of eating puffed food,and the lower the frequency of eating vegetables,the higher the children’s other obstacle scores.Conclusion: 1.The average blood lead level of children aged 1-6 in Shenyang was26.68μg/L,and that of children with blood lead level over 50μg/L was 5.13%,indicating a significant decrease in blood lead level.Often eating puffed food is the main risk factor of high blood lead level in children.In this study,the blood lead level of children had no significant effect on children’s psychological and behavioral problems.2.The frequency of consuming puffed food,milk and dairy products,fruits and vegetables is associated with the occurrence of emotional disorders,character defects,social maladjustment,communication defects,bad habits,behavioral disorders and other disorders of children;Residential environment decoration is the main risk factor of children’s character defects;The high education level of fosterers is the protective factor of children’s social maladjustment.The protective factors of children’s behavior disorders are the girls,the younger the age,and the higher the education level of the mother.High family living standards are protective factors for children’s communication deficits and other disorders. |
