Risk Factors for Geo-Helminthiasis in Children Aged 6 - 36 Months in a Rural Health District in Cameroon

Introduction and Objectives: Soil-Transmitted-Helminthiasis (STH) is a public health problem in Cameroon. The control strategies currently in place, particularly chemoprevention, has shortcomings linked to the target population, which are school-age children. The objective was to determine the prevalence and the risk factors associated with geo-helminthiasis in children aged 0 to 3 years in a rural health district. Method: From December 2020 to May 2021, a descriptive and analytical cross-sectional study of 376 children between 6 and 36 months was carried out in the Akonolinga health district. This was a cluster sampling in 4 health areas. Stool samples were collected and analysed using the mini-FLOTAC method. The results expressed as the number of eggs per gram of stool. A questionnaire on socio-demographic and lifestyle data was administered to the parents. The Chi-squared test was used to measure the association between geo-helminth infection and the data collected. A multivariate analysis using logistic regression was performed (p 0.05). Results: The prevalence of STH was 19.4% (Ascaris lumbricoides: 16% and Trichuris trichiura: 8%). Risk factors were: consumption of contaminated water (AOR = 1.93 [1.03 - 3.6];p = 0.040), early contact of the child with the ground (before age of 4 months) (AOR = 4.9 [2.1 - 11.37];p .001), habit of walking barefoot (AOR = 2.91 [1.1 - 7.97];p = 0.038), and living in a habitat with unpaved ground (AOR = 7.4 [1.55 - 35.7];p = 0.012). Conclusion: The prevalence of STHs in infants was high. Preventive chemotherapy should be extended to this age-group, and other measures intensified.

Factors Associated with Acute Respiratory Infections in Children Aged 0 - 5 Years in the Yénawa District of Cotonou (Benin) in 2023

Introduction: Acute respiratory infections remain one of the main causes of mortality in children aged 0 to 5. This work aimed to study the associated factors with the occurrence of acute respiratory infections in children 0 to 5 years old in Yénawa, Cotonou in 2023. Subjects and Method: It was an analytical cross-sectional study of children aged 0 - 5 years and their mothers in Yénawa, selected by four-degree random sampling. The sampling size, calculated using the Schwartz formula, was 126 children and 126 mothers. The dependent variable was the occurrence of acute respiratory infections. The independent variables were classified into four groups: socio-demographic and economic characteristics, behavioral factors, child-related factors, and environmental factors. Data collected by observation and questionnaire survey were analyzed using STATA version 15 software. Associated factors were investigated by bivariate analysis and multiple logistic regression, at the 5% significance level. Results: A total of 126 children aged 0 - 5 years and 126 mothers were surveyed, aged 23.5 (11 - 36) months and 30 (18 - 48) years respectively. The prevalence of acute respiratory infections was 74.60% (CI95% = 66.89 to 82.30). The associated factors were the mother’s age between 18 and 28 (OR = 10.77;CI95% = 1.89 to 61.27;p = 0.007), the use of charcoal/wood for cooking (OR = 7.36;IC = 1.99 to 27.10;p = 0.003)), children's poor personal hygiene (OR = 8.87;IC = 2.92 to 26.97;p 0.001)), and cohabitation with domestic animals (OR = 7.27;IC = 1.67 to 31.71;p = 0.015). Conclusion: Communicating with mothers about the factors identified will help reduce the prevalence of acute respiratory infections in children aged 0 to 5.

The Correlation between Social Anxiety and Loneliness of Left-Behind Children in Rural China: Effect of Coping Style

In this study, the relationship between social anxiety, coping style and loneliness amongst left-behind children was investigated. The participants were 773 left-behind children recruited from 8 junior middle schools in rural areas of Zhejiang Province in China who completed the Social Anxiety Scale for Children, Simplified Coping Style Questionnaire and Children’s Loneliness Scale. Results show that there was a moderate correlation between social anxiety and loneliness, and these variables had a significant negative relationship with positive coping style and a significant positive relationship with negative coping style. Furthermore, the left-behind children’s social anxiety, coping style and loneliness were different within specific demographic groups, such as gender, only child status and different type of parental work. Also negative coping style moderated the association between loneliness and social anxiety, so that children who were more likely to use negative coping strategies showed a stronger relationship between social anxiety and loneliness. Finally, the left-behind children’s social anxiety not only directly predicted their loneliness, but also had an indirect effect mediated by their copying style.

Parental Migration’s Effects on the Academic and Non-Academic Performance of Left-Behind Children in Rural China

This study investigates the impact of parental labor migration on the academic achievements and non-academic growth of left-behind children in fourth and seventh grades. Employing survey data collected from rural China in 2014, 2015, and 2016, we examine the effect of parental absence on children's academic achievement using Propensity Score Matching(PSM) and Difference in Difference(DID) methods. The results demonstrate that left-behind children whose parents have migrated for one year have statistically significantly lower academic scores. Academic scores drop lower for fourthgrade students and students from higher-income families. There are also adverse effects on left-behind children's confidence, teacher-student relationships, subjective well-being, and educational expectations if parents migrate for one year. Surprisingly, if parental migration lasts longer(totaling two years), these adverse effects disappear, and student's educational expectations even improve. These results may be because, over time, the adverse effects that occur immediately after parental migration are offset by the positive effects of migration(i.e. higher income). These conclusions can inform migrant parents on ways to utilize their resources to improve the academic performance of their left-behind children.

留守还是流动?--家庭化迁移对儿童认知能力和非认知能力的影响

近年来,人口城镇化进程的加快得益于大规模进城务工的流动人口,这同时也引发了学者对其子女流动儿童与留守儿童问题的关注。现有文献关于家庭化迁移过程对儿童人力资本影响效应的研究结论并不清晰,因此本文基于2010—2018年中国家庭追踪调查(CFPS)数据,使用工具变量法探讨了迁移对儿童认知能力和非认知能力的影响。结果显示,迁移可显著提高儿童的认知能力约0.051个标准差,提高非认知能力约0.032个标准差。通过进一步机制分析发现,相较于留守子女,父母对流动子女的教育支出和陪伴时间显著增加,这是流动儿童人力资本水平提高的重要原因。此外,本文在进一步探讨中聚焦于家庭化迁移对流动儿童中“离城不回乡”的再迁儿童的异质性影响,细化了流动儿童分类,拓展了现有研究对该群体的认识。

Narration and Healing of Psychological Trauma in Chinese Left-behind Children

The problem of left-behind children appears under the background of China’s industrialization,urbanization and modernization with the deepening of its reform and opening up. From 1980s,literature began to give attention to this special phenomenon.Many writers wrote about children’s psychological trauma in alienated families and social environment,and also gave suggestions on the healing of left-behind children’ psychological trauma in their works. This paper argues that the weakening of family education,the deficiency of schooling and the low social coordination are essential factors that lead to the psychological trauma of left-behind children in rural China. Joint effort from family,school and society contribute to the healing of the trauma,among which,love,writings and speeches are effective ways.

Good Experience of Values Education Mode in the UK and the US for the "Left-behind" Children's Values Education in China

Based on the development status and development characteristics of the "left-behind" children, we analyze the current situation of the "left-behind" children's values education in China. After studying the training methods and mode of young people's values in the US and Europe, we reflect on the "left-behind" children's values education in China, and point out the following deficiencies in the "left-behind" children's values education in China: the traditional Chinese culture is at the ebb, and socialist core values have not received close attention, being developed sluggishly; the educational content is stale and the method is single; the rise of science education leads to the decline of humanities education, hindering comprehensive human development. We draw the following precious experience from the values education in the UK and the US for the "left-behind" children's values education in China: laying great emphasis on humanities education, to promote comprehensive human development; seeking and reshaping the mainstream values under plural values; giving full play to the social forces, to promote the development of the "left-behind" children's values education.

Path of Student Volunteer Organizations in Agricultural Universities for Serving Rural Left-behind Children: A Case Study of Northwest A&F University

Most volunteer organizations in universities focus their attention on urban communities and residents,but neglect rural residents.Agricultural universities have responsibilities and conditions to serve rural areas,and should bring into play their leading role. This study surveyed situations of volunteers of Northwest A&F University serving rural left-behind children,and found that there are problems including weak volunteer awareness,unstable organization members,imperfect organization construction,and lack of effect incentive mechanism. Finally,it came up four recommendations: strengthening " active service" ideological education,improving management system construction,establishing incentive mechanism,and setting up brand project,to provide feasible path for agricultural universities serving rural weak groups in a better way.

Preliminary Study on Crime Prevention of Left-behind Children in Rural China

In the process of social and economic development in China,there appears the inevitable problem of crime of left-behind children.Extensive researches and disputes prove that it is,to a greater extent,a social phenomenon resulted from social factors. It is recommended to improve the treatment of migrant workers and solve the problem of school admission for their children,provide effective legal education for those left-behind children whose problem can not be solved in a short term,and supplement the guardianship role to control the crime rate of leftbehind children. Another more effective method is to resume effective control of people's social life through the rural cultural tradition,to fundamentally prevent crime of left-behind children.

Current Situation and Mental Health and Intervention Measures of Left-behind Children

In the Outline of the Twelfth Five-Year Plan for National Economic and Social Development of the People's Republic of China,it proposed of improving distribution and form of urbanization and strengthening urbanization management. With acceleration of the urbanization,numerous rural labors flow to cities,and the number of left-behind children becomes increasingly large,which not only increases burden of family and education,but also gives rise to many mental problems. Due to lack of family education,many left-behind children have mental,emotional and ethical disorder and problem,which creates hidden trouble for building a harmonious society and economic development. This paper analyzed current situation and factors influencing mental health of left-behind children,including family environment,grandparent upbringing,and school environment. Finally,it came up with pertinent intervention measures from changing ideas of parents,improving the relationship between parents and children,and improving mental health education of schools.

Research of Problems of Left-behind Children in the View of Inclusive Education

Inclusive Education is one of the most advanced educational concepts at the present time. It advocates raising the participation of children and alleviating the exclusion problems between them at the same time. Although China is a large agricultural country, under the situation of fast-growing economic development, an increasing number of adults prefer to work in big city,we call this"working fever". This situation contributes to a growing number of Left-behind children, the problem became severer. As a major receiver of basic education in China, Left-behind children may easily suffering from the problems due to their family. This violates the original intention of Inclusive Education.

The Adverse Effect of the 2-1-1 Regimen for Rabies PEP in Preschool Children

Post-exposure prophylaxis（PEP） has proved to be the most important measure for rabies prevention and control. There is little information regarding adverse reactions to the Essen and 2-1-1 regimens in preschool children（aged 0-6）. We reexamined the outcomes of 1,109 preschool children who were vaccinated using SPEEDA under the Essen regimen between January 2011 and December 2012 and 1,267 preschool children under the 2-1-1 regimen between January 2013 and December 2014. We find that, in preschool children, the febrile reaction after the first 2-dose injection in the 2-1-1 regimen was significantly higher than that induced by the first 1-dose in the Essen procedure. Thus, we recommend that the Essen regimen should still be used for rabies PEP in preschool children.

Prevalence and Years Lived with Disability for Dental Caries among Children Aged 0-14 Years in China, 1990-2016

The estimate of dental caries among Chinese children at the microscale level using standard methodology remains unclear. In this study, we assessed and analyzed the disease burden of childhood dental caries in China by extracting data from the Global Burden of Disease, Injuries, and Risk Factors Study 2016 （GBD 2016）. In 2016, the number of cases, prevalence, years lived with disability （YLD）, and age-standardized YLD rate of dental caries was 93.0 million, 43.0%, 32,200 person years, and 14.8 per 100,000, respectively. Across 33 provincial units, the disease burden was highest in Hubei （YLD rate 28.6 per 100,000）, lowest in Macao （9.1 per 100,000）, while geographical clustering was not observed. Compared with 1990, the prevalence in 2016 decreased from 46.8% to 43.0%, and the YLD rate decreased from 16.5 per 100,000 to 14.8 per 100,000. Given the slight decrease in dental caries burden, the prevalence and disease burden remained high among Chinese children. Strategies for addressing the spatial inequity of childhood dental caries require geographical targeting.

The Relationships between Serum Concentration of IGF-I and Left Ventricular Function as well as Coronary Collateral Circulation in Patients with Coronary Artery Disease

Objective To investigate therelationships between serum concentration of insulin -like growth factor - I (IGF-I) and left ventricular function as well as coronary collateral circulation in patients with coronary artery disease (CAD) . Methods In 41 patients with CAD and 15 control subjects without CAD, the concentrations of serum IGF - I were measured using radioimmunoassay. The relationships between the concentration of serum IGF - I and Leaman coronary artery score, Rentrop grade of coronary collateral circulation, left ventricular ejection fraction (LVEF) as well as left ventricular wall motion Cortina score were assessed. Results 1. There was no significant difference in the mean level of serum IGF -I between the CAD group and the control group (107. 92±44.74 ng/ml vs 113.05 ±33. 65 ng/ml, P> 0. 05), but the IGF - I concentrations in the subgroup with collateral circulation were significantly greater than that in the control group (147. 33 ±29. 92 ng/ml vs 113. 05±33. 65 ng/ml, P < 0. 01) or in the subgroup without collateral circulation (147. 33 ±29. 92 ng/ml vs 80. 01±29. 75 ng/ml , P < 0. 01). 2. The serum concentration of IGF -I had no significant correlation to the Leaman coronary artery score. 3. The serum level of IGF -I had significantly positive correlation to both LVEF ( r = 0. 45, P < 0. 001) and the Rentrop grade of coronary collateral circulation ( r = 0. 74, P < 0. 001), and was negatively related to the left ventricular wall motion Cortina score (r = -0. 53, P < 0. 001). 4. The Leaman coronary artery score had no significant correlation to the Rentrop grade of coronary collateral circulation. 5. The Leaman coronary artery score was related to neither the LVEF nor the Cortina score in the whole CAD group. In the subgroup without coronary collateral circulation, however, the Leaman score had significantly negative correlation to LVEF ( r = - 0. 46, P < 0. 05) and positive correlation to the Cortina score (r = 0. 47, P < 0. 05) . Conclusions The serum concentration of IGF -I was associated with both left ventricular function and coronary collateral circulation in patients with CAD. IGF -I may play a role in promoting coronary collateral circulation and in protecting left ventricular function in patients with coronary artery disease.
