Independent sample t-test and one-way ANOVA were used to compare the differences in physical fitness indexes of preschool children in different groups. Chi square test and binary Logistic regression model were used to analyze the factors affecting physical health of preschool children.@*Results@#The total qualified rate of physical fitness was 79.75%, among which the excellent rate was 3.16%, the good rate was 15.12%, the qualified rate was 61.47% and the unqualified was 20.25%. From the perspective of BMI, the excellent physical fitness rate (3.74%) and good physical fitness rate ( 17.47% ) were highest in healthy weight preschool children, and the qualified physical fitness rate of overweight preschool children (69.03%) was higher than that of obese (55.88%) and healthy weight preschool children (60.68%)( χ 2=53.56, P <0.01). From the perspective of ethnic, Tibetan children s physique proficiency (3.69%), good rate ( 17.13% ) than with the elevation of the Han nationality (0.74%, 5.88%), fraction defective (16.97%), lower than that of Han nationality (35.29%) ( χ 2=53.71, P <0.01); The results of chest circumference, skinfold thickness, body fat percentage, tennis throw distance, continuous jump of both feet, sitting forward bend and balance beam walking of Tibetan children were higher than those of Han children, and the results of quiet heart rate and standing long jump were lower than those of Han children ( t = 2.72 , 10.95, 9.66, 3.68, 3.88, 8.04, 3.56, 8.70, -4.39 , -4.40, P <0.01). Binary Logistic regression analysis showed that Tibetans ( OR =2.29), breastfeeding ( OR =1.51), body dynamics outdoor daily exercise duration 30-90 min (30-<60 min ;OR = 2.03 ; 60-90 min: OR =2.22) were positively correlated with physical health of preschool children ( P <0.05).@*Conclusions@#The total physical qualification rate of preschool children aged 3-6 years old in Tibet is lower than the national average. Ethnic group, feeding pattern during infancy, and physical activity are all factors that affected the physical fitness of preschool children in Tibet. It is of great significance to improve the physique of preschool children in Tibet to promote their sustainable and healthy development.

Preschool Children Feeding Patterns And Early Childhood Oral Health Impact In Tanah Merah, Kelantan, Malaysia

@#Introduction: Poor feeding patterns increase risk of Early Childhood Caries (ECC), which can cause negative impacts on oral health-related quality of life (OHQoL) of preschool children and parents. This study aims to assess feeding patterns of preschool children and OHQoL of the children and their parents in Tanah Merah. Methods: A cross-sectional study was conducted involving 134 preschool children aged 5-6 years old from eight private preschools, chosen by multi-staged stratified cluster sampling. Parents answered adopted self-administered questionnaire on feeding patterns and oral health-related impacts. Mann-Whitney U test and Kruskal-Wallis test were used to compare the median between groups of feeding patterns. Results: A total of 122 parents responded. Majority of the children had history of bottle-feeding (97.5%) and being given solid food during infancy (61.2%). Many children were still using bottle to drink (38.5%). Majority were still given formula milk at least three times daily (51.1%) and were feed with bottle to put to sleep (97.9%). The Child Impact Section (CIS), Family Impact Section (FIS) and Overall ECOHIS mean scores were 2.39 (SD=3.41), 0.71 (SD=1.45) and 3.10 (SD=4.41), respectively. Most common impact reported in CIS was ‘oral pain’ (26.2%) whereas in FIS, ‘parents felt guilty’ (7.4%). None of feeding patterns were found significantly different in terms of ECOHIS score median (p-value>0.05). Children OHQoL reporting by proxy should be treated as complementary. Conclusion: Many preschool children were involved in prolonged, frequent and nocturnal bottle-feeding. No significant difference in median ECOHIS scores found according to feeding patterns.

Cluster characteristics of physical activities among children inside and outside kindergartens and its relationship with athletic abilities / 中国学校卫生

Objective@#Based on physical activity (PA) and sedentary behavior (SB) variables on weekdays and weekends, the study aims to cluster the physical activities inside and outside kindergartens and to explore the cluster characteristics of different children using physical fitness indicators, so as to provide new strategies and methods for early childhood education and health.@*Methods@#From March to June 2019, 291 children aged 3-6 years from 6 kindergartens in Nanchang were recruited by a stratified cluster random sampling method. The ActiGraph GT3X-BT triaxial accelerometer was used to measure and analyze the PA and SB levels inside and outside the kindergarten. A twostep clustering algorithm model was employed for cluster analysis. Physical fitness were measured and evaluated according to the "National Physical Fitness Measurement Standard Manual (Preschool Section)". Differences in physical fitness among different clusters of children were compared, and the cluster characteristics of different children were analyzed.@*Results@#The clustering algorithm model indicated that based on six indicators, including PA and SB inside the kindergarten on weekdays, and PA and SB outside the kindergarten on both weekdays and weekends, children could be divided into three categories:active inside (high PA, low SB inside), active outside (high PA outside), and inactive (low PA, high SB both inside and outside). The average silhouette coefficient of the model was 0.3, indicating good clustering results. Both the active inside and active outside children showed significantly higher PA inside on weekdays, PA outside on weekdays and weekends, daily low intensity physical activity (LPA) and moderate-to-vigorous physical activity (MVPA) than the inactive children ( F=157.91, 80.79 , 95.86, 95.52, 124.74, P <0.05). After adjusting for gender and age, the physical fitness scores of both active outside ( 19.03 ±0.47) and active inside (19.11±0.40) were significantly higher than those of the inactive children (17.94±0.31). Additionally, active inside children (3.91±0.14) also showed significantly better performance in continuous double-leg jumps, compared to inactive children (3.45±0.11) ( P <0.05).@*Conclusion@#Children active inside and those active outside perform well in PA. Future research should focus on the proportion of structured and unstructured PA time to enhance the overall physical fitness of children.

Objective@#To evaluate the effectiveness of sex education curriculum on sex related knowledge, attitude and practice of preschool children in senior class, so as to provide a reference basis for the comprehensive development of early childhood sex education in the future.@*Methods@#From December 2021 to July 2022, the two stage stratified sampling method was used to select 12 kindergartens in Luzhou City, of which 6 senior classes were chosen as the intervention group (360 before the intervention, 354 after the intervention), and the other 6 senior classes as the control group (416 before the intervention, 326 after the intervention). The intervention group was conducted with early childhood sex education classes in the form of a series of courses, with a total of four topics including one parent course and three child courses every month, while the control group received routine teaching schedule. A survey was conducted on the knowledge, attitude and practice of early childhood sex education among preschool children and their parents before and after the intervention. χ 2 text analysis was used to carry out the effect.@*Results@#There was no statistically significant difference in sexual education related knowledge, attitude and practice between the intervention group and the control group before intervention ( P >0.05). There were statistically significant differences in the awareness rate of sexual knowledge (77.4%, 69.6%), positive attitude rate (73.7%, 10.1%), good practice rate (59.3%, 38.0%), and good knowledge, attitude and practice rate (37.9%,1.8%) between the intervention group and the control group after intervention ( χ 2=5.28, 279.77, 30.77, 134.62, P <0.05). Similar findings were observed in the intervention group before and after the intervention ( χ 2=63.39, 344.31 , 41.41, 161.03, P <0.05). The difference in the awareness rate of sexual related knowledge between the control group before and after intervention was statistically significant ( χ 2=44.29, P <0.05).@*Conclusion@#The early childhood sex education curriculum might help improve sex related knowledge, attitude and practice. Kindergartens should be encouraged to actively promote sex education, training, and guidance for preschool children and their parents, in order to improve the sex related knowledge, attitude and practice.

Eating behaviors and associated factors among preschool children in Tongling City / 中国学校卫生

Objective@#To examine the eating behaviors and associated factors among preschool children from multiple child families, so as to provide a basis for promoting healthy eating habits in this population.@*Methods@#From April to June 2022, a stratified random cluster sampling method was employed to selected 2 647 guardians of preschool children in 11 kindergartens in Tongling City. Parenting style questionnaire, Identification and Management of Feeding Difficulty Questionnaire (IMFeD), Caregiver s Feeding Style Questionnaire (CFSQ) and a self designed questionnaire were administered. Multiple linear regression was performed to analyze the factors influencing eating behaviors among preschool children.@*Results@#In the study, the detection of eating behavior problems among preschool children was 71.4%, and the detection of reduced appetite was the highest (55.6%). The detection rates of anorexia, picky eating, poor eating and improper eating behavior in only child families were higher (60.6%, 41.0%, 32.0%, 19.5%), compared with those in multiple child families (51.7%, 36.4%, 27.2%, 16.6%) ( χ 2=20.05, 5.95, 7.16, 3.92, P < 0.05 ). Among multiple child families, the detection rates of fear of eating and underlying disease were the lowest in 5-<10-year-old group (2.3%, 0.6%) ( χ 2=11.54, 8.51, P <0.05). In multiple child families, the detection rates of picky eating and poor eating habits for the first-born child were higher (42.0%, 32.5%), compared with second born and third born child (34.6%, 25.6%)( χ 2= 6.15, 6.38, P <0.05). The results of multiple linear regression analysis showed that multiplechild families ( β =-1.40), democratic parenting style ( β =-0.07), higher feeding response scores ( β =-0.33) were negatively associated with eating behavior problems among preschool children ( P <0.05). Eating behavior problems among preschool children were positively correlated with less educated mothers [high and junior high school education ( β =0.87), primary school education and below ( β =3.69)], longer average daily screen time ( β =0.10), higher feeding requirements scores ( β =0.64), doting parenting styles ( β =0.21), permissive parenting styles ( β =0.27) and inconsistent parenting styles ( β =0.14)( P <0.05).@*Conclusion@#The detection rate of the eating behaviors problems among preschool children is high in schools. Greater attention should be paid to only child and first born child of multiple child families, and appropriate feeding and parenting styles, so as to promote healthy eating habits among this population.

Analysis of influencing factors of Helicobacter pylori infection in obese preschool children / 中国医师杂志

Objective:To explore and analyze the influencing factors of Helicobacter pylori (HP) infection in obese preschool children.Methods:From May 2020 to May 2022, 50 obese preschool children with HP infection and 50 obese preschool children without HP infection were prospectively selected from Tangshan Maternal and Child Health Hospital. We collected and collected basic data on two groups of children, including gender, age, eating habits, and family related information. Single factor analysis was used to screen for possible influencing factors of HP infection in obese preschool children, and logistic regression analysis was performed on the selected influencing factors.Results:Single factor analysis of variance showed that there were statistically significant differences in the prevalence of HP infection among obese preschool children of different ages, body mass index (BMI), sharing tableware, per capita monthly income of families, using public chopsticks, washing hands before meals, partial eating, habit of biting fingers, family population, binge eating, family history of HP infection, etc. (all P<0.05). Multivariate logistic analysis showed that BMI ( OR=1.576, 95% CI: 1.119-2.221), shared tableware ( OR=1.317, 95% CI: 1.018-1.702), per capita monthly income of households ( OR=1.330, 95% CI: 1.021-1.733), no use of public chopsticks ( OR=1.408, 95% CI: 1.019-1.945), washing hands before meals ( OR=1.206, 95% CI: 1.041-1.397), habit of biting fingers ( OR=1.470, 95% CI: 1.064-2.031), binge eating ( OR=1.443, 95% CI: 1.004-2.074) and family history of HP infection ( OR=1.317, 95% CI: 1.051-1.649) were the influencing factors of HP infection in obese preschool children (all P<0.05). Conclusions:BMI, shared tableware, per capita monthly income of families, failure to use public chopsticks, washing hands before meals, habit of biting fingers, binge eating, family history of HP infection, etc. are the influencing factors of HP infection in obese preschool children. If there are children with abnormal related factors, attention should be paid to them. If there are related infection symptoms, targeted interventions can be taken in time to prevent and control children′s HP infection.

Research progress on the association between screen exposure and autism spectrum disorder in preschool children / 中国学校卫生

Abstract@#Autism spectrum disorder (ASD) is a lifelong neurodevelopmental disorder. Early life social experience assessment before symptoms of ASD might be helpful for determining the causal link between social experiences and early childhood ASD. Younger children are exposed to excessive screen time in recent years. This paper summarizes the association between screen exposure with ASD in preschool children, and proposes future research directions and provides evidencebased guidance to optimize and support children s early media experiences.
