Brain-derived neurotrophic factor is a crucial neurotrophic factor that plays a significant role in brain health. Although the vast majority of meta-analyses have confirmed that exercise interventions can increase brain-derived neurotrophic factor levels in children and adolescents, the effects of specific types of exercise on brain-derived neurotrophic factor levels are still controversial. To address this issue, we used meta-analytic methods to quantitatively evaluate, analyze, and integrate relevant studies. Our goals were to formulate general conclusions regarding the use of exercise interventions, explore the physiological mechanisms by which exercise improves brain health and cognitive ability in children and adolescents, and provide a reliable foundation for follow-up research. We used the Pub Med, Web of Science, Science Direct, Springer, Wiley Online Library, Weipu, Wanfang, and China National Knowledge Infrastructure databases to search for randomized controlled trials examining the influences of exercise interventions on brain-derived neurotrophic factor levels in children and adolescents. The extracted data were analyzed using Review Manager 5.3. According to the inclusion criteria, we assessed randomized controlled trials in which the samples were mainly children and adolescents, and the outcome indicators were measured before and after the intervention. We excluded animal experiments, studies that lacked a control group, and those that did not report quantitative results. The mean difference(MD;before versus after intervention) was used to evaluate the effect of exercise on brain-derived neurotrophic factor levels in children and adolescents. Overall, 531 participants(60 children and 471 adolescents, 10.9–16.1 years) were included from 13 randomized controlled trials. Heterogeneity was evaluated using the Q statistic and I^(2) test provided by Review Manager software. The meta-analysis showed that there was no heterogeneity among the studies(P = 0.67, I^(2) = 0.00%). The combined effect of the interventions was significant(MD = 2.88, 95% CI: 1.53–4.22, P < 0.0001), indicating that the brain-derived neurotrophic factor levels of the children and adolescents in the exercise group were significantly higher than those in the control group. In conclusion, different types of exercise interventions significantly increased brain-derived neurotrophic factor levels in children and adolescents. However, because of the small sample size of this meta-analysis, more high-quality research is needed to verify our conclusions. This metaanalysis was registered at PROSPERO(registration ID: CRD42023439408). 展开更多

Mycoplasma pneumoniae(M.pneumoniae)is a common pathogen that causes community-acquired pneumonia in children.The clinical presentation of this pathogen can range from mild self-limiting illness to severe and refractory cases.Complications may occur,such as necrotizing pneumonia and respiratory failure.Extrapulmonary complications,including encephalitis,myocarditis,nephritis,hepatitis,or even multiple organ failure,can also arise.In this editorial,we dis-cuss the clinical implications of the significant findings from the article"Serum inflammatory markers in children with M.pneumoniae pneumonia and their predictive value for mycoplasma severity"published by Wang et al.They reported that measuring lactic dehydrogenase,interleukin-6 levels,and D-dimer effectively predicts refractory M.pneumoniae pneumonia cases. 展开更多

BACKGROUND Although breast milk is ideal for newborns,in some cases,it is replaced with cow’s milk,which contains proteins that increase the risk of cow’s milk protein allergy(CMPA).AIM To evaluate CMPA prevalence in Bahrain and compare clinical characteristics of children with immunoglobulin E(IgE)-and non-IgE-mediated CMPA.METHODS This retrospective cohort study examined children with CMPA diagnosed at the pediatric gastroenterology outpatient clinic of the Salmaniya Medical Complex,Bahrain,between 2014 and 2022,and assessed CMPA prevalence.Clinical presentations,laboratory findings,dietary modifications,and outcomes were compared between children with IgE-mediated and non-IgE-mediated CMPA.Categorical variables were compared using Fisher’s exact test or Pearson’sχ2 test,whereas continuous variables were compared using Student’s t-test or the Mann-Whitney U test.RESULTS Of 8332 patients,6022(72.3%)adhered to their appointment.Of them,618(10.3%)were suggested of having CMPA and 595(96.3%)were included;CMPA prevalence was 2%.Most patients were Bahraini(93.8%)and males(55.3%).Non-IgE-mediated type accounted for 77.3%cases and IgE-mediated type,22.7%.IgE-mediated CMPA presented more in boys(P=0.030),and later in life(5.1 months±4.5 months vs 4.2 months±4.2 months,P=0.016,95%CI:0.08-1.73),had more associated diseases(P<0.001);and presented with more cutaneous(P=0.024)and respiratory(P=0.003)manifestations,severe symptoms[rash/dry skin(P=0.031),facial swelling/angioedema(P=0.003),failure to thrive(P=0.013),apparent life-threatening event(P<0.001)],and positive physical findings(P=0.002)than non-IgE-mediated CMPA.Most patients were exclusively fed cow milk formula(50.3%).The amino acid-based formula(AAF)was most prescribed(60.5%)with no difference between the two types(P=0.173).Although breastfeeding was recommended to 49.6%,only 8.2%were exclusively breastfed.IgE-mediated CMPA was associated with a longer follow-up duration than non-IgE-mediated CMPA(17.3 months±14.0 months vs 13.5 months±13.4 months,P=0.005,95%CI:1.1-6.3).CONCLUSION This study revealed a high CMPA prevalence with clinical differences between both types that can influence treatment.AAF was most prescribed,while breastfeeding with dietary modification is rarely applied. 展开更多

BACKGROUND Picky eating is a commonly observed behavior among children globally,negatively impacting their physical and mental growth.Although common characteristics distinguish peaky eaters,including food selectivity,food neophobia,and food avoidance,there is no clear definition to assess this behavior.Due to the unavailability of data regarding picky eating,it wasn’t easy to estimate its prevalence.AIM To develop a regional protocol to help healthcare professionals identify and manage mild and moderate picky eating cases.METHODS A virtual roundtable discussion was held in April 2021 to gather the opinions of seven pediatricians and two pediatric dietitians from eight Middle Eastern countries who had great experience in the management of picky eating.The discussion covered different topics,including clearly defining mild and moderate picky eating,identifying the role of diet fortification in these cases,and the possibility of developing a systematic approach to diet fortification.RESULTS The panel identified picky eating as consuming an inadequate amount and variety of foods by rejecting familiar and unfamiliar food.Most of the time,moderate picky eating cases had micronutrient deficiencies with over-or undernutrition;the mild cases only showed inadequate food consumption and/or poor diet quality.Paying attention to the organic red flags like growth faltering and development delay and behavioral red flags,including food fixation and anticipatory gagging,will help healthcare professionals evaluate the picky eaters and the caregivers to care for their children.Although dietary supplementation and commercial food fortification play an important role in picky eating,they were no benefit in the Middle East.CONCLUSION The panel agreed that food fortification through a food-first approach and oral nutritional supplements would be the best for Middle Eastern children.These recommendations would facilitate identifying and managing picky-eating children in the Middle East. 展开更多

The severe environment in Qinling-Daba Mountains has made it not suitable for the long-term residence due to the large amounts of "ecological migrants", and these migrants have moved out of the mountains and changed their economic and life styles, resulting in many problems. In this paper, the problems of "ecological migrants" were analyzed, including the education problem, different life styles, incomplete national protecting measures and policies, with the aim to provide governments with constructive suggestions for the establishment of the education and training system, acceleration of the development of industries (especially the tertiary industry, subsidiary business), and labor transferring, increasing the incomes of "ecological migrants", and making the "ecological migrants" have the financial resources for a long time, thereby better stabilizing the "ecological migrants". 展开更多

The grounded theory of qualitative methods was applied to researching the social integration of tourism la-bor migrants in the Jiuhua Mountain of Anhui Province, China. The research was conducted based on the in-depth in-terviewing of 15 samples, open-consultation and the analysis of secondhand data. The integration models of tourism labor migrants in the Jiuhua Mountain were formed through four processes including theoretic sampling, cod-ing-analysis, cross-tabulation and contextualization. The result shows that modes of production and life styles decide self-integration orientation of tourism labor migrants in the Jiuhua Mountain. Cultural differences are fundamental dis-similarity between tourism labor migrants and natives. There are three kinds of integration models including rapid, free and gradually advancing integration. The differences among different types of migrants’ integration models are re-markable. Taking the working integration as the abscissa and taking the life integration as the coordinate, an "S" model of integration matrix appears in the gradually advancing integration of intermediate and high administers from the working to the life which should be paid special attention to. 展开更多

We assessed the risk of overweight and obesity for six large migrant groups in Switzerland. We used population-based survey data form the Swiss Migrant Health Survey 2010 and the Swiss Health Survey 2007. The sample comprised permanent residents aged 17 - 64 years (n = 14,637). Multivariate logistic regressions have been used to estimate odds ratios (OR). Compared with Swiss nationals, the odds of being obese were 1.97 times higher for Turkish nationals (CI-95 1.26, 3.07), 1.73 times higher for Kosovan nationals (CI-95 1.09, 2.74) and 3.42 times higher for Serbs (CI-95 2.28, 5.12). The chance of being obese was not statistically different between Swiss nationals and those from Portugal, Italy, and Germany. The chance of being overweight or obese (BMI ≥ 25) was higher for migrants than for Swiss nationals. The respective odds were 1.54 times higher for nationals from Portugal (CI-95 1.13, 2.11), 2.05 times higher for those from Turkey (CI-95 1.50, 2.78), 2.67 times higher for those from Serbia (CI-95 1.93, 3.68), 2.68 times higher for those from Kosovo (CI-95 2.01, 3.56), and 2.16 times higher for nationals from Italy (CI-95 1.54, 3.02). We suggest that preventive initiatives should take into account the specific needs of migrants as well as the needs of persons with low education from all nationalities. 展开更多

Objective To examine the relationship between overweight or obesity and the risk of the various hypertension hemodynamic subtypes in Yi farmers and migrants. Methods A cross-sectional study of 2 358 Yi farmers and 2 392 Yi migrants was carried out in the Liangshan Yi autonomous prefecture, Sichuan, China in 2007. Results The standardized prevalence of overweight in female Yi farmers (6.22%) was higher than in males (3.25%), whereas in Yi migrants 32.56% of males and 28.78% of females were overweight. The standardized prevalence of obesity was 0 and 0.62% in male and female Yi farmers, compared to 3.91% and 5.57% in male and female Yi migrants, respectively. For both genders the standardized prevalence of ISH, IDH, and SDH was higher in Yi migrants than Yi farmers. Overweight and obese Yi men and women had a higher risk for IDH and SDH (P〈O.002) than non-overweight/obese individuals. However, an association of overweight or obesity with ISH was observed only in men. Conclusion Yi migrants have substantially higher proportion of overweight and obese individuals, as well as individuals affected by ISH, IDH, and SDH, than do Yi farmers. Overweight and obesity are significant risk factors for the development of hypertension in Yi people. 展开更多

Objective: The objective of this study was to investigate the diagnostic methods of high altitude de-acclimatization syndrome and to formulate diagnostic criteria. Methods: This study was conducted using epidemiological surveys and a multi-center randomized controlled clinical trial. A total of 3011 subjects were studied, and the following indices were collected after their return to low altitude areas from the plateau: general health status, blood, urine and stool samples, myo-cardial enzyme levels, liver and kidney function, nerve function, sex hormone levels, microalbuminuria, electrocardiogram (ECG), echocardiography, pulmonary function, and hemorheological markers. These data were compared to those of randomized healthy subjects in the same age range who lived at the same altitude to determine the characteristics of high altitude de-acclimatization syndrome. Based on these characteristics, diagnostic criteria for high altitude de-acclimatization syndrome were formulated. Results: This study demonstrated that the incidence of high altitude de-acclimatization syndrome was 84.36%. Sixty percent of the cases were mild, 30% were medium, and 10% were severe. The incidence was higher among those who returned to a place of lower altitude, resided at a high altitude for a longer period of time, or engaged in heavy labor while at high altitude. Patients with high altitude de-acclimatization syndrome manifested hematological abnormalities and abnormal ventricular function, notably a right ventricular diastolic function, which recovered to baseline function after one to five years. Exposure to long-term hypoxia often caused obvious changes in cardiac morphology, i.e., left and right ventricular hypertrophy, particularly within the right ventricle. In addition, patients with high altitude de-acclimatization syndrome often presented with low blood pressure, low pulse pressure, and microalbuminuria. A few patients presented with occult blood in their feces. The diagnosis of high altitude de-acclimatization syndrome can be made if a patient who recently returns to the plain from the plateau complains of dizziness, weakness, sleepiness, chest tightness, edema, memory loss, and other symptoms and signs that do not alleviate under short-term rehabilitation or symptomatic treatment, and if organic diseases of the heart, lung, kidney, and other organs have been excluded. Conclusion: The diagnosis of high altitude de-acclimatization syndrome should be made after a comprehensive analysis of the patient’s clinical symptoms and signs. 展开更多

The Three Gorges Project attracts worldwide attention because of the Three Gorges migrants, and the agriculture of the Three Gorges Reservoir Area is a foundation for the development of the Three Gorges migrants. The Three Gorges Reservoir Area is situated at the mountainous area with bad agricultural development conditions and relatively low levels of development. As a result, the large-scale migration fias special influence on its agricultural development, which has attracted much attention. The paper analyzes influence that the migrants have forced on its agricultural development based on the scientific data, and makes some explorations on the models that are suitable for the development of mountainous agriculture in the Three Gorges Reservoir Area. 展开更多

The extant literature on international immigrants has discussed migrants’entrepreneurial activities in the context of Western countries but has paid little attention to return-home entrepreneurial intention(RHEI).Rural migrant workers(RMWs)in China,who used to promote rural development by remittances and were characterized by similarities with early international migrants,have gradually returned to their hometowns to initiate entrepreneurial activities.Based on the structured questionnaire conducted in 2015 and 2020in Anhui Province,China,this article combines the concept of mixed embeddedness with the idea of double-layered embeddedness and analyzes the impacts of the social,economic and institutional context in RMWs’hometowns and migration destinations on RMWs’RHEI by using binary logistic regression.The article shows that the social,economic,and institutional environments of RMWs’hometowns and migration destinations have effects on their RHEI.The embeddedness in the economic and informal institutional context in RMWs’RHEI is even more important than personal characteristics.Compared with migration destinations,RMWs’hometowns exert a more influential effect on their RHEI.However,that does not mean that the role of migration destinations can be undervalued.Actually,the better the social,economic,and institutional environments of migration destinations RMWs moved into is,the higher entrepreneurial intention they will have after returning to their hometowns.The article proposes a modified framework in combination of mixed embeddedness with double-layer embeddedness and proves that it is suitable for analyzing RMWs’RHEI.The framework has important implications for strengthening China’s RMWs to return home to start their own businesses. 展开更多

Old-age pension, a fundamental part of the Chinese social security system, is perceived by the Chinese government as the last support for rural-to-urban migrant workers upon retreating from the labor market. Using survey data collected by the authors, this paper examines a host of factors which influence migrant workers' participation in the old-age scheme. The result shows that individual characteristics, employment status, attitudes toward old-age support and perception of the old-age pension system significantly differentiate two groups of migrant workers between those that have participated in and their counterparts who have not participated in the old-age pension schemes. Among a number of factors, age, educational attainment, holding labor contract, etc. are found to be significant factors influencing migrants' behavior participating(or not participating) the available age-pension schemes. Policy implications for how to improve the rate of participation in existing old-age pension schemes among migrant workers are drawn from the findings. 展开更多

Under the background of accelerated integrated urban-rural development, this paper offers an analysis on the short-term employment of rural migrants in China and resulting wage gap between long-term and short-term rural migrants. On the basis of correcting for sample selection problems arising from labor market participation and short-term employment, rural migrants' wage function is estimated using quantile regression method, and wage gap between long-term and short-term rural migrants is decomposed using MM method. Our empirical results suggest that those with a higher level of education, training experience and local employment recommended by family relations or in formal labor market are more likely to secure long-term labor contract," region and education have significant contributions to the wage of rural migrants," rural migrants of both long- and short-term contract types have great gaps at the bottom of salary distribution; and there exists a sticky floor effect in wage difference of rural migrants. These results have important policy implications in enhancing employment stability of rural migrants, improving income distribution equity, speeding up the process of urbanization, and balancing regional development. 展开更多

Objectives To investigate relationship between iron deficiency of different degrees and physical performance and habitual activity of migrant schoolchildren at the age of 11-14 years. Methods Ninety one randomly selected schoolchildren were divided into three groups according to their iron status. Iron status including hemoglobin (Hb), serum ferritin (SF), serum iron (SI) and sTfR was determined. Physical performance tests included maximum oxygen consumption (VO2max) and maximum work time. Energy expenditure (EE) and daily physical activity were estimated by recording 24-h heart rate (HR). Dietary intake was assessed with frequency questionnaires, and physical activity level was estimated with frequency and physical activity questionnaires. Results Severe iron deficiency (IDA) impaired the aerobic capacity and habitual physical activity. When fat-free mass (FFM) was considered, VO2max (VO2max/FFM) was significantly lower in the iron-marginal group than in the iron-adequate groups among girls (P=0.02), but such a deference was not found among boys (P=0.28). Aerobic activity and EE at leisure were significantly lower in the severe iron deficient group than in the marginal iron deficient and iron adequate groups. Net HR at leisure time was correlated with lib, log SF, body weight, and FFM (P〈0.05). Conclusion The functional effect of iron deficiency on physical performance and habitual physical activity rely on the degree of current iron deficiency. Severe iron deficiency significantly impairs both aerobic capacity and habitual physical activity. Iron-marginal deficiency impairs VO2max/FFM in girls, rather than in boys. 展开更多

Our premise for this literature review is the global demographic change caused by the world’s population living longer and becoming older, and extensive international migration leading to multicultural societies. Increasing age leads to health problems, often long-term or chronic, requiring investments in health care. Worse health and dissimilarities in pattern of morbidity/ mortality have been found in foreign-compared to Swedish-born persons, so it is reasonable to assume that this affects use of health care. The exploratory review focuses on elderly migrants’ (>65 years) use of healthcare. The databases Pub Med, EBSCO, CINAHL and ERIC were searched in 2000-2013. A limited number of studies were found;few had a comparative approach, most were from the USA, and focused on migrants from the former Soviet Union or countries in South-East Asia. A range of factors were identified that influence patterns of health care use: language fluency, ability to communicate, self-reported health status, prevalence of chronic disease, physical distance from care provision, availability of transport to reach care, cost of care, the health insurance system, cultural norms and values regarding different forms of care, level of education, and length of residence in the host country. Most studies treated health care from a general perspective and collected data from community and hospital settings, without analysing usage separately. Some studies indicated elderly migrants making use of health care less than other groups but the pattern is not unambiguous: other studies show that there is an overuse of health care. It is therefore difficult to show any particular pattern, or possible differences in use, regarding community versus in-patient care. Studies focusing on migrants’ actual use of health care are few and further research is needed, especially because elderly people form the largest group of users of health care and will be even larger in the future. 展开更多

Countries and places have introduced a number of policies to address the issue in a timely manner. At first, this paper analyzes the compulsory education policy for migrant workers' children and off-site college entrance policy, then find that there are still many problems in the formulation and implementation of policy. In the future, the relevant departments should be through improving the social status of migrant workers, increasing efforts to support the private school children of migrant workers, increasing investment in adult education, increasing the publicity of city, such the four aspects of policy guidance to coordinate and solve the education of migrant workers' children. 展开更多

Objective To understand the perception of potential condom use and its influencing factors so as to promote condom use among unmarried migrantsMethod A survey, using self-administered structured anonymous questionnaire, was conducted among 1 092 unmarried migrants aged 15~24 years old in urban area of Shanghai. Results The unmarried migrants had some knowledge of condom. However, their knowledge level and their attitude towards condom use were not so optimistic. Subjects' knowledge of contraceptives and STD/AIDS had a positive influence on their attitude toward condom use. Subjects with positive attitude to condom use were more likely to use condom in sexual activity (OR=1.61). Conclusion Unmarried migrants have lower rate of condom use if they have insufficient knowledge of condom. Therefore, it is essential to strengthen the sexual health education among unmarried sex-active migrants in order to encourage contraceptive use, especially condom use. 展开更多
