Objective: To explore the association between executive function and emotional and behavioral problems in first-grade elementary school students, so as to provide a reference for promoting children s mental health. Methods: From March to May 2024, 423 first-grade elementary school students from 6 primary schools aged 6-7 were selected by using stratified cluster random sampling in Shanxi, Shanghai, Shandong, Guangxi, Xinjiang, and Jiangxi. Data were collected by using the Executive Function Assessment Scale and the Strengths and Difficulties Questionnaire. An independent samples t-test was used to analyze differences in executive function of different genders and differences in emotional and behavioral problems among first-grade school students with varying executive function levels; a linear regression model was employed to analyze the association between children s executive function and emotional and behavioral problems. Results: A total of 42 first-grade elementary school students (9.9%) were identified as having executive function deficits. Students in the executive function deficit group scored higher on internalizing behavior (7.50±0.52), externalizing behavior (11.26±0.52), and total difficulties (18.52± 0.93 ) were significantly higher than those of children without deficits (4.37±0.14, 6.69±0.17, 10.64±0.27) ( t =5.79, 8.50, 9.23, all P <0.05). Results of linear regression analysis showed that, after controlling for relevant covariates such as gender, age, family economic status, being an only child, and body mass index, the factor scores, dimensional scores, and total scores of executive function were all positively correlated with scores for externalizing problems, internalizing problems, and total difficulties ( β =0.07-0.32, all P <0.05). Conclusions Children s executive function is closely associated with emotional and behavioral problems, and those with poorer executive function exhibit more pronounced emotional and behavioral problems. Improving children s executive function may help promote their mental health.

Objective To evaluate the relationship between the trend of glutamyl transpeptidase(GGT)change and newly developed metabolic syndrome(MS),and to explore the relationship between GGT and MS.Methods The study was a prospective cohort study,with baseline data sourced from the Beijing subcenter population of the"REACTION"study.A total of 6482 non-MS subjects was enrolled as the study subjects,and divided into four groups using the quartile method based on GGT level:G1(GGT<14.2 U/L,n=1613),G2(14.2≤GGT<18.6 U/L,n=1602),G3(18.6≤GGT<26.1 U/L,n=1639)and G4(GGT≥26.1 U/L,n=1628)group.Follow up was conducted 3.2 years later to analyze the correlation between baseline GGT and the trend of GGT changes with the risk of new MS.Results Baseline GGT was a risk factor for newly diagnosed MS.Compared with G1 group,the relative risk(RR)(95%CI)of newly diagnosed MS at follow-up in G2,G3,G4 group were 1.480(1.220～1.780,P<0.01),2.090(1.750～2.490,P<0.01),and 2.800(2.360～3.320,P<0.01),respectively.The increase in GGT is a risk factor for newly diagnosed MS during follow-up in this population.Compared with the group with decreased GGT,the RR(95%CI)of newly diagnosed MS during follow-up was 1.410(1.320～1.510)(P<0.01)in the group with increased GGT.In stratified subgroup analysis,the incidence of new-onset MS was[1.650(1.410～1.940)vs 1.510(1.310～1.750),P<0.01]respectively in female and middle-aged people in the GGT increase group compared with the GGT decrease group.There was no statistically significant difference in the risk of developing new MS in both male and elderly populations between the GGT increasing group and the decreasing group(P>0.05).Conclusions The increase in GGT is a risk factor for newly diagnosed MS,especially in female and middle-aged populations.

Objective To analyze the association between fatty liver index(FLI)and the risk of newly diagnosed diabetes mellitus(DM)in people with different glucose metabolism.Methods A retrospective cohort study was conducted,with baseline data sourced from the Beijing sub center population of the REACTION study.The follow-up was conducted 3.2 years later.A total of 6425 non DM subjects were included in this study,and divided into four groups using the quartile method based on FLI level:Q1(FLI＜11.68,n=1608),Q2(11.68≤FLI＜24.33,n=1607),Q3(24.33≤FLI＜44.73,n=1604)and Q4(FLI≥44.73,n=1606).Results During follow-up,a total of 556 new DM patients were found,with a cumulative incidence rate of 8.7%.Logistic regression analysis showed that FLI level was an independent risk factor for new DM patients,whether in non-DM people,NGT subgroups or IGR subgroups.In non DM population,the risk of developing new DM in the Q1,Q2,Q3 is 1.650 times(95%CI 1.200～2.290,P=0.002),2.040 times(95%CI 1.420～2.940,P＜0.001),and 2.950 times(95%CI 1.860～4.670,P＜0.001)higher than that in the Q1,respectively.In the NGT population,the risk of newly diagnosed DM in the Q3,Q4 is 1.670 times higher(95%CI 1.010～2.750,P=0.045)and 2.320 times higher(95%CI 1.410～3.800,P=0.001)than that in the first quartile,respectively.FLI level is an independent risk factor for newly diagnosed DM in the IGR population(P=0.012).The risk of newly diagnosed DM in the Q2,Q3,Q4 is 1.480 times(95%CI 1.080～2.020,P=0.015),1.620 times(95%CI 1.190～2.220,P=0.002),and 1.630 times(95%CI 1.180～2.250,P=0.003)higher than that in the Q1 respectively.Conclusions FLI is significantly associated with the risk of new onset DM in both NGT and IGR populations,and is an independent risk factor for newly diagnosed DM.

Objective:To analyze the correlation between fatty liver index (FLI) and myocardial remodeling.Methods:For cross-sectional study, cluster sampling was used to conduct a follow-up study of “Risk evaluation of cancers in Chinese diabetic individuals: A longitudinal (REACTION) study” among communities of Gucheng and Pingguoyuan of Beijing from April 2015 to September 2015. According to the inclusion and exclusion criteria, 8 848 participants were selected. Biochemical indicators such as body mass index, waist circumference, triglycerides, and γ-glutamyl transpeptidase were detected to calculate the FLI. The correlation between FLI and myocardial remodeling was analyzed. Interventricular septal thickness (IVS), left atrial diameter (LAD), left ventricular end diastolic diameter (LVEDD), and the presence of diastolic dysfunction were measured by color doppler ultrasound. The participants were divided into Q1 group (FLI<30, 4 529 cases), Q2 group (30≤FLI<60, 2 762 cases), and Q3 group (FLI≥60, 1 557 cases) based on FLI levels. Single factor analysis of variance was used for inter-group comparison, logistic regression analysis was used to analyze the correlation between FLI and myocardial remodeling.Results:A total of 8 848 subjects were selected for the study (3 110 male and 5 738 female, mean age: 59.96 years). The IVS of Q1, Q2, and Q3 groups were (9.35±1.08), (9.73±1.22), and (10.07±1.31) mm, respectively. The LAD were (30.94±3.90), (33.37±4.12), and (34.98±4.47) mm, respectively. The LVEDD were (42.51±5.05), (44.43±5.10), and (46.06±5.52) mm, respectively. All increased with the increase of FLI (all P<0.001). FLI was an independent risk factor for IVS thickening, LAD increase, LVEDD increase, and diastolic function decrease. The respective risks for IVS thickening, LAD increase, LVEDD increase, and diastolic function decrease in a population with intermediate and higher FLI levels was 1.62 times (95% CI 1.39-1.89) and 2.53 times (95% CI 2.13-3.00); 2.71 times (95% CI 2.39-3.06) and 5.00 times (95% CI 4.12-6.08); 2.36 times (95% CI 1.85-3.00) and 4.33 times (95% CI 3.33-5.62); and 1.90 times (95% CI 1.63-2.19) and 1.95 times (95% CI 1.60-2.37) than those with lower FLI levels. Conclusion:There is a certain relevance between FLI and myocardial remodeling.

Objective:To analyze the correlation between fatty liver index (FLI) and the outcomes of individuals with high normal blood pressure.Methods:In this retrospective cohort study, data from the follow-up population of the Beijing branch of the Risk Evaluation of Cancers in Chinese Diabetic Individuals: A Longitudinal (REACTION) study conducted from December 2011 to August 2012 were selected. Obtain indicators such as height, weight, waist circumference, fasting blood glucose, 2-h postprandial blood glucose, triglycerides, high-density lipoprotein cholesterol, and glutamyl transpeptidase were measured, and the FLI was calculated. The population with high normal blood pressure was divided into the FLI<30 group (1 822 cases); 30≤FLI<60 group (1 026 cases); and FLI≥60 group (473 cases) based on FLI levels. The blood pressure outcome data from the follow-up survey of this population from April 2015 to September 2015 were collected. Single factor analysis of variance was used for intergroup comparison, and logistic regression was used to analyze the correlation between FLI and the outcome of high normal blood pressure in the population.Results:The FLI was an independent influencing factor for their conversion to normal blood pressure (all P<0.01). Among all observed populations, the likelihood of conversion to normal blood pressure in the 30≤FLI<60 group and FLI≥60 group was 0.63 (95% CI 0.51-0.78) and 0.61 (95% CI 0.45-0.82) of the FLI<30 group, respectively. In the population of 40≤age<60 years, this likelihood was 0.60 (95% CI 0.47-0.76) and 0.57 (95% CI 0.41-0.79), respectively. FLI is not an independent influencing factor for the conversion to normal blood pressure in individuals aged over 60 years ( P=0.161). FLI is an independent risk factor for hypertension (all P<0.05). Among all observed populations and population of 40≤age<60 years and age>60 years, the risk of hypertension in the 30≤FLI<60 group and FLI≥60 group was 1.49 times (95% CI 1.23-1.80) and 1.54 times (95% CI 1.19-1.98); 1.41 times (95% CI 1.13-1.75) and 1.38 times (95% CI 1.04-1.83); and 1.75 times (95% CI 1.22-2.53) and 2.10 times (95% CI 1.24-3.58) of the FLI<30 group, respectively. Conclusions:There is a correlation between FLI levels and future outcomes of individuals with normal high blood pressure. Although people with higher FLI are more likely to develop hypertension, those with higher FLI are also less likely to develop normal blood pressure in the 40≤age<60-year group.

Objective:To analyze the trend of disease burden of oral cancer attributable to smoking in China from 1990 to 2019, and predict the mortality trend of oral cancer from 2020 to 2034, providing scientific basis for formulating targeted oral cancer prevention and treatment strategy to achieve the goal of "Healthy China 2030".Methods:Using partial data on the global burden of disease in China in 2019, attributive death and disability adjusted life year (DALY) were used to describe. The trend of changes in the burden of oral cancer disease attributed to smoking was analyzed by using the Joinpoint regression model to estimate the annual average percentage change (AAPC) of age standardized mortality and DALY rates. Meanwhile, the Bayesian age-period- cohort model is used to predict oral cancer deaths and DALY trends attributed to smoking over the next 15 years.Results:The age-standardized mortality rate and DALY rate in China from 1990 to 2019 showed an overall upward trend, with an average annual increase of 1.49% (95 %CI: 1.34%-1.65%, P<0.001) and 1.41% (95 %CI: 1.24%-1.59%, P<0.001) respectively, higher than around the earth and in regions with different socio-demographic index (SDI). In 2019, 46.74% (10 584/22 642) of oral cancer deaths in China were attributed to smoking. Compared to 1990, the number of attributed deaths in 2019 increased by 293.75% (7 896/2 688), while DALY increased by 257.97% (189 039/73 280). Moreover, the growth rates of attributed deaths and DALY in males [304.95% (7 584/2 487) and 265.60% (183 349/69 033), respectively] were significantly higher than those in females [154.73% (311/201) and 133.95% (5 690/4 248), respectively] ( P<0.001). The age group results showed that the proportion of deaths and DALY gradually transitioned towards the elderly (>60 years old). The expected number of deaths would increase from 10 731 in 2020 to 14 125 in 2034, with a rise of 31.63% (3 394/10 731). Simultaneously, DALY would increase from 267 064 person years in 2020 to 326 634 person years in 2034, with a rise of 22.31% (59 570/267 064). Conclusions:From 1990 to 2019, the burden of oral cancer diseases attributed to smoking in China showed an increasing trend, with a higher growth rates than in the global and different SDI regions. There were differences in gender and age, and the burden of oral cancer diseases attributed to smoking in China would continue to increase in the next 15 years. It is necessary to educate on the adverse effects of tobacco consumption and to conduct vigilant oral self-examination among high-risk groups to help early detection and intervention at the same time.

Cognitive health is key for older adults to live independently, and exercise intervention can improve cognitive health.Exercise improves cognitive health through a variety of mechanisms, including improvement of cerebral blood perfusion, enhancement of brain capacity and connectivity, promotion of neurogenesis, and release of neurotrophic factors, miRNA and myokines.The exercise mode and dose can affect the effect of exercise intervention on cognitive health.Individualized exercise intervention with a duration of more than 12 weeks and a multi-mode combination is more conducive to improving the cognitive health of older adults.
