Objective@#To systematically evaluate the effect of mini basketball on children s upper limb strength in China, and to provide basis for the development of kindergarten mini basketball and the improvement of children s upper limb strength performance.@*Methods@#CNKI, Wanfang Data, VIP, PubMed, and Web of Science databases were searched from the establishment of the database to July 26, 2023. The PICOST model was used for literature screening, and 13 literature with a total of 20 studies were finally included. The Cochrane System Evaluation Criteria was used for literature quality evaluation. Review Manager 5.4 and Stata 17 were used for statistical analysis and publication bias test.@*Results@#A total of 939 children were included in 20 studies, including 470 in the experimental group and 469 in the control group. Meta analysis showed that mini basketball had an extremely significant effect on the improvement of children s upper limb strength ( SMD=0.83, 95%CI=0.53-1.13, Z=5.40, P < 0.01 ). The results of subgroup analysis showed that there was no significant gender difference in the improvement of children s upper limb strength by mini basketball ( P >0.05), mini basketball exercise with an intervention time of less than or equal to 30 minutes ( SMD=0.49, 95%CI=0.29-0.70, Z=4.70, P <0.01) and an exercise cycle of more than 12 weeks ( SMD=1.25, 95%CI=0.54-1.96, Z= 3.45 , P<0.01) can achieve a better intervention effect on the upper limb strength of children. Meta regression results showed that the exercise intervention time was the main source of heterogeneity ( t=2.71, 95%CI= 1.38-22.93, P <0.05). Egger s test showed that the publication bias of the included studies was not statistically significant ( t=0.78, P >0.05).@*Conclusions@#Mini basketball training can improve the upper limb strength of children, but there is no significant gender difference. The upper limb strength is affected by the restriction of intervention time and exercise cycle. Schools can appropriately add small basketball in physical education classes to improve children s upper limb strength.

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.

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.

Association of pre school children physical activities and sedentary behaviors on calcanues bone density / 中国学校卫生

Objective@#To investigate the effects of physical activity (PA) intensity and sedentary behavior (SB) on calcanues bone mineral density (BMD) in preschool children, so as to provide a basis for rationalizing the daily physical activity of preschool children to promote bone health.@*Methods@#A total of 673 pre school children aged 3-6 years from nine kindergartens in Pingxiang City, Ganzhou City and Yingtan City of Jiangxi Province, were selected from September to December 2021 by using the whole stratified cluster random sampling method. The PA levels and SB were measured by using a three axis acceleration sensor, and left calcanues BMD was measured by an ultrasound bone densitometer. Multiple linear regression was used to explore the effects of changes in PA on calcanues BMD in pre school children of all ages.@*Results@#Of the 673 preschoolers surveyed, 498 (74.0%) achieved an average of ≥60 min of moderate to vigorous physical activity (MVPA) per day, there were 265 boys (71.2%), and 233 girls ( 77.4 %). The difference between genders was not statistically significant ( χ 2=2.77, P >0.05). There was no statistically significant difference in the BMD test of the calcaneus bones of preschoolers by gender ( Z=0.42, P >0.05). The difference in BMD results of pre school children with 3, 4, 5 to 6 years was statistically significant ( H=2.65, P <0.05). Correlation analysis revealed a negative correlation between SB duration and calcaneus BMD ( r =-0.13), and a positive correlation between low intensity physical activity (LPA) duration, MVPA duration, and calcaneus BMD ( r =0.14, 0.25 ) ( P <0.05). Multivariate linear regression analysis showed that SB duration negatively correlated with calcaneus BMD, whereas LPA and MVPA duration positively correlated with calcaneus BMD ( P <0.05).@*Conclusions@#MVPA duration is positively correlated with the growth of BMD in the heel bone and negatively correlated with SB. The kindergartens can adjust their curricula according to the physical and mental developmental characteristics, gender and age differences of pre school children, increase the time of outdoor activities, and reduce the sedentary time to promote the bone health of young children.
