Long-term exposure to ambient air pollution and metabolic syndrome in children and adolescents: A national cross-sectional study in China.

Background: The prevalence of metabolic syndrome (MetS) rapidly increased over the past decades. However, little evidence exists about the effects of long-term exposure to ambient air pollution on MetS in children and adolescents.

Associations of MGMT promoter hypermethylation with squamous intraepithelial lesion and cervical carcinoma: A meta-analysis.

Background: In this research, an meta-analysis was performed for assessment of the associations between O6-methyguanine-DNA methyltransferase (MGMT) promoter hypermethylation possessing low-grade intraepithelial lesion (LSIL), high-grade intraepithelial lesion (HSIL), cervical cancer (CC), and clinicopathological characters of CC.

Methods: Literature selection were conducted through searching PubMed, Web of science, EMBASE, China National Knowledge Infrastructure and Wanfang databases (up to November 2018). An assessment of associations between MGMT methylation and LSIL, HSIL, CC risk and clinicopathological characteristics was performed through pooled odds ratios (ORs) with relevant 95% confidence intervals (CIs).

[Study on the willingness of care and related influencing factors among caregivers of those stranded children under 7 years in Chinese rural areas].

Objective: To explore the willingness of care and related influencing factors among caregivers of those 'left at hometown' children under 7 years in Chinese rural areas.

Methods: Questionnaires were used to survey caregivers (n = 7585) who were identified by multi-stage stratified cluster sampling. Multi-factor ordinal logistic regression analysis was used to screen the influencing factors on the willingness of care among them.

Results: The prevalence of difficulty among left-behind children was 3.

[A case-control study on genetic and environmental factors regarding polydactyly and syndactyly].

Objective: To explore the genetic and environmental factors related to the development of polydactyly and syndactyly, and to provide evidence for prevention on birth defects.

Methods: A hospital-based case-control study was conducted. 111 cases and 222 controls were interviewed with standardized questionnaires.

[Knowledge, attitude, practice and related determinants on nutrition among caregivers of rural stranded children under 7-year-olds in China].

Objective: To explore knowledge, attitude, practice (KAP) and related determinants on nutrition among caregivers of those rural stranded children under 7 years of age in China and to provide evidence for setting up relevant health education program.

Methods: 1691 caregivers of the stranded children randomly selected were surveyed by a standard questionnaire. Logistic regression models were used to screen the determinants on KAP regarding nutrition.

[Study on emotional, behavioral problems and related determinants among stranded children aged 4 to 7 years in the rural areas of China].

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).

[Study on the nutritional status and determinants among rural stranded children in China].

Objective: To explore the nutritional status and determinants among rural stranded children under 7 years of age.

Methods: The group of stranded children (n=7585) and the children for control (n=7557) were identified by multi-stage stratified cluster sampling. The ascertainment methods mainly included questionnaire, anthropometric measurements and laboratory examination.

[Using multivariate multilevel model in studying the influential factors of violence among rural high school students in Changsha].

Objective: To provide evidence for setting up violence intervention programs in rural middle schools, through studying the influential factors.

Methods: Taking variables including emotional, physical and sexual violence in the past year as the multi-dependent variables before multivariate multilevel model logistic regression model was adopted to analyze the correlations among the three kinds of violence and the influential factors.

Results: Among 3620 respondents, the incidence rates of emotional, physical and sexual violence weres 21.

[Investigation on dietary nutrients among rural stranded children of 2-7 year olds in china].

Objective: To understand the dietary nutrients among rural stranded children.

Methods: 2551 children aged 2 to 7, including 1278 stranded children in the rural areas and another 127 children served as controls were selected, using multistage stratified cluster random sampling. Dietary survey was performed with three-day weighing dietary method and questionnaire on food intake.

[Risk prediction model of perinatal congenital heart disease].

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.

[The status on care and nutrition of 774 children staying in rural areas while parents were in towns].

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.
