RESUMO
Objective@#To analyze the status and correlation between screen time, screen behavior type, and anxiety, depression among children and adolescents in Jiangxi Province, so as to provide a basis for effective intervention measures.@*Methods@#Using the method of stratified random sampling, 8 851 primary and secondary school students in 11 districts of Jiangxi Province were investigated by questionnaire during September to December in 2020. Anxiety and depression status were investigated using the State Trait Anxiety Inventory (STAI) and the Center for Epidemiological Studies Depression Scale for Children(CES-DC), respectively. Single factor analysis using χ 2-test, t-test,analysis of variance,and multivariate analysis using generalized linear models.@*Results@#On school days and weekends, 4.7% and 20.4% of primary and secondary school students in Jiangxi Province had a total screen time of over 2 hours per day, respectively. The weighted scores of the total screen time (primary school students: 1.88± 0.68, junior middle school students: 1.96±0.71, high school students: 2.03±0.80) and time spent for playing video games (primary school students: 1.51±0.64, junior middle school students: 1.62±0.69, high school students: 1.68±0.75) daily showed an upward trend with the increase of educational stage ( F =31.48, 42.13), and with significantly higher in boys (1.97±0.74, 1.66± 0.72) than girls (1.93±0.72, 1.53±0.66)( t =2.48, 9.07)( P <0.05). The average scores of state anxiety and trait anxiety were (42.20±9.05) and (40.65±9.85), which showed an upward trend with the increase of educational stage ( F =168.12, 241.98 ), and were higher in girls than boys ( t =6.63, 8.48)( P <0.01). The average score of depression was (11.99±11.00), which was lower in elementary school students than middle school students and high school students ( F =136.42), with significantly higher in girls ( t =6.85)( P <0.01). On school days, with the increase of total screen time and time spent for playing video games daily, the risk of state anxiety, trait anxiety, and depression among primary and secondary school students significantly increased ( OR = 6.70- 818.98, P <0.01). On weekends, among primary and secondary school students, the total screen time of >1-2 hours daily reduced the risk of state anxiety ( OR =0.30). The risk of developing trait anxiety among students playing video games for more than 2 hours daily was 2.50 times higher than those without screen behavior ( OR =2.50). The risk of developing depression with a total screen time of more than 2 hours daily was 3.15 times higher those whithout screen behavior ( OR =3.15). The risk of developing depression among students playing video games >0-1, >1-2, >2 h daily was 2.14, 2.50, 4.90 times that of those without screen behaviors ( OR =2.14, 2.50, 4.90), and showed an upward trend with the increase of educational stage ( P <0.05).@*Conclusions@#Screen behaviors of primary and middle school students in Jiangxi Province are positively associated with the risk of anxiety and depression, but the total daily video time of >1-2 h on weekends was negatively associated with state anxiety. It is necessary to control the screen time as much as possible and reduce the risk of anxiety and depression.
RESUMO
Objective@#To investigate blood lipid status among children and adolescents in Jiangxi Province, and to provide the basis for prevention and control of dyslipidemia.@*Methods@#Using the method of stratified cluster random sampling,a total of 14 535 children and adolescents aged 6-17 years old were selected from Jiangxi Province in 2019. With physical measurement and blood tests for fasting blood total cholesterol(TC), triglyceride(TG),high-density lipoprotein cholesterol(HDL-C),and low-density lipoprotein cholesterol(LDL-C) levels, dyslipidemia was determined by the definition of dyslipidemia prevention consensus of specialists in Children and Adolescents.@*Results@#The dyslipidemia rate was 14.9%, and the abnormal rates of TC,TG, LDL-C and HDL-C were 5.9%,7.4%,2.9% and 3.4%, respectively.The prevalence of dyslipidemia was higher in female(15.7%) than in male(14.1%)(χ 2=8.01, P<0.01). The prevalence of dyslipidemia in primary school, middle school and high school students was 13.8%,15.5% and 17.3%, respectively(χ 2=21.14，P<0.01),and in students of normal weight, overweight and obesity was 12.8%, 21.9%, 30.0%, respectively(χ 2=297.20, P<0.01).@*Conclusion@#The prevalence of dyslipidemia among children and adolescents in Jiangxi Province is lower than the national level, but the current situation cannot be ignored.
RESUMO
Objective@#To investigate prevalence and influencing factors of overweight and obesity among children and adolescents in Jiangxi Province, and to provide the basis for strategies for prevention and treatment of overweight and obesity.@*Methods@#Using stratified random cluster sampling ,a total of 77 780 primary and middle school students in 11 districts of Jiangxi Province were investigated with physical examination and questionnaire during March to November in 2019.@*Results@#The detection rates of overweight and obesity of children and adolescents in Jiangxi province were 20.5% and 8.4%, respectively. Which decreased with the increase of the learning stage（ χ 2=178.65, 389.86）,with significantly higher in boys and urban areas （ χ 2=1 061.06, 504.21;56.17, 34.14）（ P ＜0.01）.In different economic areas, the detection rates of overweight and obesity in moderate economic area( 23.3 %, 9.7%) were the highest, followed by high economic area (21.1%, 8.7%) and low economic area(18.2%, 7.2%), and the differences were statistically significant（ χ 2=266.29, 143.90， P ＜0.01）.The results of multivariate Logistic regression analysis showed that in terms of social demography, overweight and obesity of children and adolescents in Jiangxi Province were associated with economic area, residence, learning stage and gender; in terms of dietary behavior, overweight of children and adolescents in Jiangxi Province was associated with consumption frequency of sugary drinks, sweets, fresh fruits and vegetables, and the influencing factors of obesity were consumption frequency of sweets and fresh fruits( P <0.05).@*Conclusion@#The situation of overweight and obesity of children and adolescents in Jiangxi Province is sorrisome, and comprehensive prevention and control should be carried out with the joint efforts of society, school and family.
RESUMO
OBJETIVO: Determinar se três variantes (388 G>A, 521 T>C, 463 C>A) do membro 1B1 da família de transportadores de ânions orgânicos portadores de solutos (SLCO1B1) se associam à hiperbilirrubinemia neonatal. FONTE DE DADOS: Foi realizada busca na Infraestrutura do Conhecimento Nacional da China e em MEDLINE. A revisão sistemática com metanálise incluiu estudos genéticos que avaliaram a associação entre hiperbilirrubinemia neonatal e as variantes 388 G>A, 521 T>C, 463 C>A de SLCO1B1 entre janeiro de 1980 e dezembro de 2012. Foi realizada seleção e extração de dados por dois analistas, de forma independente. SUMÁRIO DOS ACHADOS: Foram incluídos dez artigos no estudo. Os resultados revelaram que SLCO1B1 388 G>A se associa a um aumento do risco de hiperbilirrubinemia neonatal (OR< 1,39; IC 95%: 1,07 a 1,82) em recém-nascidos chineses, mas não em recém-nascidos caucasianos, tailandeses, latino-americanos ou malaios. A mutação SLCO1B1 521 T>C mostrou baixo risco de hiperbilirrubinemia neonatal em recém-nascido chineses, e não foram encontradas associações importantes no Brasil nem em recém-nascidos caucasianos, asiáticos, tailandeses e malaios. Não houve diferenças significativas da SLCO1B1 463 C>A entre o grupo com hiperbilirrubinemia e o grupo controle. CONCLUSÃO: O estudo mostrou que a mutação 388 G>A do gene SLCO1B1 é fator de risco para desenvolver hiperbilirrubinemia neonatal em recém-nascidos chineses, mas não em populações caucasianas, tailandesas, brasileiras ou malaias; a mutação SLCO1B1 521 T>C fornece proteção de hiperbilirrubinemia neonatal em recém-nascidos chineses, mas não nas populações caucasianas, tailandesas, brasileiras ou malaias.
OBJECTIVE: To determine whether three variants (388 G>A, 521 T>C, and 463 C>A) of the solute carrier organic anion transporter family member 1B1 (SLCO1B1) are associated with neonatal hyperbilirubinemia. DATA SOURCE: The China National Knowledge Infrastructure and MEDLINE databases were searched. The systematic review with meta-analysis included genetic studies which assessed the association between neonatal hyperbilirubinemia and 388 G>A, 521 T>C, and 463 C>A variants of SLCO1B1 between January of 1980 and December of 2012. Data selection and extraction were performed independently by two reviewers. SUMMARY OF THE FINDINGS: Ten articles were included in the study. The results revealed that SLCO1B1 388 G>A is associated with an increased risk of neonatal hyperbilirubinemia (OR, 1.39; 95% CI, 1.07-1.82) in Chinese neonates, but not in white, Thai, Latin American, or Malaysian neonates. The SLCO1B1 521 T>C mutation showed a low risk of neonatal hyperbilirubinemia in Chinese neonates, while no significant associations were found in Brazilian, white, Asian, Thai, and Malaysian neonates. There were no significant differences in SLCO1B1 463 C>A between the hyperbilirubinemia and the control group. CONCLUSION: This study demonstrated that the 388 G>A mutation of the SLCO1B1 gene is a risk factor for developing neonatal hyperbilirubinemia in Chinese neonates, but not in white, Thai, Brazilian, or Malaysian populations; the SLCO1B1 521 T>C mutation provides protection for neonatal hyperbilirubinemia in Chinese neonates, but not in white, Thai, Brazilian, or Malaysian populations.
