Metabolic Disorders Increase the Risk to Incident Cardiovascular Disease in Middle-aged and Elderly Chinese

Objective The association of metabolic syndrome （MetS） with cardiovascular diseases （CVD） has not been adequately explored in middle-aged and elderly Chinese. This study aimed to investigate MetS＇ prevalence and its impact on the CVD incidence in this specific population group. Methods A data set of a community-based prospective cohort study was analyzed. A total of 2300 subjects aged 40-94 years were followed up for the CVD events. MetS defined according to the JCDCG criteria was assessed at baseline, and the middle-aged and elderly groups were classified by the WHO definition. Results As compared with the middle-aged group, the prevalence of MetS increased by 0.6 times （34.6% vs. 21.3%） and the incidence density of CVD increased by 4.9 times in the elderly group （52.3/1000 person-year vs. 8.9/1000 person-year）. Furthermore, the multivariate Cox regression revealed that the risk to CVD incidence was independently related to increased waist circumference in the middle-aged group （HR=2.23, P〈0.01） and to elevated blood glucose in the elderly group （HR=1.39, P〈O.01）. Conclusion MetS was highly prevalent in middle-aged and elderly Chinese. MetS significantly increased the risk to OdD incidence in the elderly. All individuals with metabolic disorders should receive active clinical care to reduce the incidence of CVD.

Public Square Dancing Intervention on Subjective Well-Being of Middle-Aged and Elderly People:A Meta-Analysis

Objective:To understand the influence of public square dancing on the subjective well-being of middle-aged and elderly people.Methods:According to the principle of Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA)guidelines,we search Chinese databases,such as CNKI,Wanfang Data,and VIP,and English databases,such as Proquest,Web of Science,Pubmed,Cochrane,and ScienceDirect,and collect relevant articles at home and abroad from 2006 to December 2019 for meta-analysis in January 2020.Result:A total of 10 articles were included.The meta-analysis results showed that the well-being of middle-aged and elderly people in the public square dancing intervention group was significantly higher than that of the other exercise group and control group(both P<0.01).The results of the subgroup analysis showed the following:Different durations of intervention significantly influence the intervention effect(P<0.01).No difference was found between the effect of the mixed-gender intervention and the individual female intervention(P>0.05).No significant difference was found between the groups with weekly intervention frequency(P>0.05).Conclusion:Public square dancing intervention is effective for middle-aged and elderly people’s subjective well-being.Neither mixed intervention nor the times of weekly intervention have an impact on the intervention effect.However,the length of duration of intervention influences the intervention effect.

Relationship between platelet-lymphocyte ratio and carotid atherosclerosis in middle-aged and elderly patients with type 2 diabetes mellitus

Objective:To investigate the relationship between platelet-lymphocyte ratio(PLR)and carotid atherosclerosis(CAS)in middle-aged and elderly patients with T2DM.Methods:A total of 420 middle-aged and elderly patients with T2DM who were hospitalized in the Endocrinology Department of our hospital from September 2018 to September 2020 and were examined by ultrasound were selected as the subjects.The carotid artery intima-media thickness(CIMT)was examined by color Doppler ultrasonography,including normal CIMT group(n=111),CIMT thickening group(n=103)and CAS plaque group(n=206).The differences of serum PLR levels among the three groups were compared.Multivariate Logistic regression was used to analyze the relationship between PLR and CAS plaque formation.The receiver operating curve(ROC)was used to evaluate the value of multivariate Logistic regression model(Logit P)in the diagnosis of CAS lesions.Results:The mean value of PLR in CAS plaque group(127.86±48.54)was significantly higher than that in CIMT normal group(109.15±48.35).Multivariate Logistic regression analysis showed that after adjusting for other confounding factors,the increase of PLR was an independent risk factor for the occurrence of CAS plaque.ROC showed that the efficacy of multivariate Logit P model in the diagnosis of CAS plaque was(AUC=0.807,95%CI=0.759-0.858).Conclusions:PLR is one of the important risk factors for the occurrence of CAS lesions.At the same time,the multivariate Logistic regression model established in this study has clinical reference value in predicting CAS lesions in middle-aged and elderly patients with T2DM.

Design Method for Optimizing the Interactive Interface of Live Broadcasting Platform for the Elderly Users

In the era of network live broadcasting for everyone,the development of live broadcasting platforms is also more intelligent and diversified.However,in the face of a large group of elderly users,the interface interaction design mode used is still mainly based on the interaction mode for young groups,and is not designed for elderly users.Therefore,a design method for optimizing the interaction interface of live broadcasting platform for elderly users was proposed in this study.Firstly,the case study method and Delphi expert survey method were used to determine the design needs of elderly users and the design mode was analysed.Secondly,the orthogonal design principle was used to design a test sample of the interactive interface of live broadcasting platform applicable for the elderly users,and then a user evaluation system was established to calculate the weights of the design elements using hierarchical analysis,and then the predictive relationship between the design mode of the interactive interface of live broadcasting platform and the elderly users was established by Quantitative Theory I.Finally,Genetic Algorithm was applied to generate the optimized design scheme.The results showed that the design method based on the Genetic Algorithm and the combination of Quantitative Theory can scientifically and effectively optimize the design of the interactive interface of the live broadcasting platform for the elderly users,and improve the experience of the elderly users.

Identification of late-onset hypogonadism in middle-aged and elderly men from a community of China

In this study, we investigated the essential criteria for late-onset hypogonadism （LOH） syndrome based on the presence of symptoms associated with low testosterone levels in Han Chinese men. Blood tests for total testosterone （TT） and sex hormone-binding globulin （SHBG） were performed, and the aging male symptoms （AMS） questionnaire was conducted in a randomly selected cohort composed of 944 Chinese men aged 40 to 79 years from nine urban communities. Three sexual symptoms （decreased ability/frequency of sexual activity, decreased number of morning erections, and decreased libido） were confirmed to be related to the total and free testosterone levels. The thresholds for TT were approximately 12.55 nmol l^-1 for a decreased ability/frequency to perform sex, 12.55 nmol l^-1 for decreased frequency of morning erections, and 14.35 nmol l^-1 for decreased sexual desire. The calculated free testosterone （CFT） thresholds for these three sexual symptoms were 281.14, 264.90, and 287.21 pmol l^-1, respectively. TT 〈13.21 nmol l^-1 （OR =1.4, 95%Ch 1.0-1.9, P= 0.037） or CFT 〈268.89 pmol l^-1 （OR - 1.5, 95%Ch 1.1-20, P=0.020） was associated with an increase in the aforementioned three sexual symptoms. The prevalence of LOH was 9.1% under the criteria, including all three sexual symptoms with TT levels 〈13.21 nmol l^-1 and CFT levels 〈268.89 pmol l^-1. Our results may improve the diagnostic accuracy of LOH in older men.

Prevalence of late-onset hypogonadism among middle-aged and elderly males in China:results from a national survey

This study aimed to propose an operational definition of late-onset hypogonadism(LOH)that incorporates both clinical symptoms and serum testosterone measurements to evaluate the prevalence of LOH in aging males in China.A population-based sample of 6296 men aged 40 years-79 years old was enrolled from six representative provinces in China.Serum total testosterone(TT),sex hormone-binding globulin(SHBG),and luteinizing hormone(LH)were measured and free testosterone(cFT)was calculated.The Aging Males’Symptoms(AMS)scale was used to evaluate the LOH symptoms.Finally,5078 men were included in this analysis.The TT levels did not decrease with age(P=0.59),and had no relationship with AMS symptoms(P=0.87 for AMS total score,P=0.74 for≥3 sexual symptoms).The cFT levels decreased significantly with age(P<0.01)and showed a negative association with the presence of≥3 sexual symptoms(P=0.03).The overall estimated prevalence of LOH was 7.8%(395/5078)if a cFT level<210 pmol l−1 combined with the presence of≥3 sexual symptoms was used as the criterion of LOH.Among them,26.1%(103/395)and 73.9%(292/395)had primary and secondary hypogonadism,respectively.After adjustment for confounding factors,primary and secondary hypogonadism was positively related to age and comorbidities.Body mass index was an independent risk factor for secondary hypogonadism.The results suggest that the AMS total score is not an appropriate indicator for decreased testosterone,and that the cFT level is more reliable than TT for LOH diagnosis.Secondary hypogonadism is the most common form of LOH.

Prevalence of stroke and metabolic disorders in the middle-aged and elderly Chinese with type 2 diabetes

Background Stroke is now the most prevalent and debilitating disease affecting diabetic population in China. The study aimed to investigate the prevalence of stroke and metabolic disorders in the middle-aged and elderly Chinese with type 2 diabetes. Methods A total of 4 629 subjects with type 2 diabetes （males： 1 917; females： 2 712） aged ≥ 40 years from Shijingshan district, Beijing, China from November 2011 to August 2012 were included in the study. Data on demographic information, lifestyle, history of diabetes mellitus, stroke, coronary heart disease, hypertension, and dyslipidemia were collected. The oral glucose tolerance test or a standard meal test was performed. Non-fatal stroke was reported by the subjects. The 2-tailed test was used, and P 〈0.05 was regarded as statistically significant. Results Prevalence of stroke in the subjects with type 2 diabetes was 5.5%. The prevalence of smoking, overweight or obesity, hypertension, and dyslipidemia was 41.0%, 65.8%, 67.4%, and 52.0% in males, and 2.2%, 65.5%, 69.5%, and 57.6% in females. Multivariate Logistic regression analysis showed that increased age, hypertension, diabetic duration, and overweight or obesity were positively correlated with stroke in the population with type 2 diabetes, whereas high- density lipoprotein cholesterol level was negatively correlated with stroke. After adjustment for age and gender, the odds ratio values of stroke in subjects having 1,2 or ≥3 of 4 risk factors, including smoking, overweight or obesity, hypertension and dyslipidemia, were 2.302 （95% CI： 0.789-6.712）, 4.089 （95% CI： 1.470-11.373）, 6.023 （95% CI： 2.176-16.666）, compared with subjects without any of the above 4 risk factors. Conclusions The prevalence of stroke was higher in middle-aged and eldedy Chinese with type 2 diabetes than that in the general population. With the aggregation of risk factors, the prevalence of stroke increased.
