Study on emotional, behavioral problems and related determinants among stranded children aged 4 to 7 years in the rural areas of China / 中华流行病学杂志

Objective To understand emotional, behavioral problems and related determinants among rural stranded children and to provide evidence for further psychological support. Methods A total of 3944 caregivers of children in the rural areas and aged 4 to 7 years but without parents around, were randomly selected. Data were collected through Strengths and Difficulties Questionnaires (the edition for parents, SDQ). Results The overall prevalence of children with behavioral/emotional problems was 43.6% among those stranded children including 8.3% having experienced emotional symptoms, 9.5% reported to be displaying 'conduct' problems, 8.7% exhibited significant hyperactivity/inattention, 18.9% experienced peer relationship problems and 16.8% having prosocial behaviors. The prevalence of behavioral/emotional problems was significantly higher in boys than those in girls and in lower age groups. Significant differences were also found in conduct problems, hyperactivity/inattention and prosocial behaviors (P<0.01). The result from logistic regression analysis showed that factors as education level and motivation of the caregivers as well as financial support from the parents were related to emotional/ behavioral problems among the stranded children. Conclusion The prevalence of emotional and behavioral problems was high among children living the rural areas but without their parents around which should call for psychological intervention.

Risk prediction model of perinatal congenital heart disease / 中华流行病学杂志

Through analyzing the influencing factors of congenital heart disease (CHD), it is aimed to establish CHD risk prediction model in fetus, and simultaneously provide theoretical foundation for CHD prevention. One-factor logistic regression method was used to screen the significant factors regarding CHD, and to separately adopt multiple-factor non-conditional logistic regression method and decision tree to set up model prediction fetus CHD risk and to analyze the advantages and shortcomings. Correct classification rates turned to be 80.93% and 82.79% respectively among 215 'training samples' by the two methods and the rates were 85.45 % and 89.09% respectively among 55 'testing samples'. The alliance of logistic regression and decision tree can overcome influence by co-linearity to guarantee the accuracy and perfection, as well as promoting the predictive accuracy.

The status on care and nutrition of 774 children staying in rural areas while parents were in towns / 中华流行病学杂志

Objective To understand the status on care and nutrition of children living in the rural areas (so called 'left-behind' children) while their parents were seeking for jobs in the urban areas. Methods Cross-sectional study was employed in this investigation.The group of‘left-behind' children (n=774) and the comparison group (n=774) were identified.The ascertainment methods mainly included questionnaire,anthropometries measurements,food-frequency,and laboratory examination.Results be poorly attended (X2=6.671,P=0.036;X2=15.053,P=0.001 ).Mothers who chose to work outside of their households would tend to choose bottle-feeding or decrease the duration of breastfeeding for their infants (X2=5.051,P=0.031;t=-7.201,P=0.001).The intake of milk and bean products in children were obviously lower than that seen in the control group (t=-2.150,P=0.032 ;t=-2.054,significant difference when comparing with the control group (X2=4.560,P=0.033 ).Conclusion communities,parents and extended families would facilitate more attention and effective intervention programs to improve the situation.
