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.

Associations of short-term ambient temperature exposure with lung function in middle-aged and elderly people:A longitudinal study in China

The short-term associations of ambient temperature exposure with lung function in middle-aged and elderly Chinese remain obscure.The study included 19,128 participants from the Dongfeng-Tongji cohort's first(2013)and second(2018)follow-ups.The lung function for each subject was determined between April and December 2013 and re-assessed in 2018,with three parameters(forced vital capacity[FVC],forced expiratory volume in 1 s[FEV1],and peak expiratory flow[PEF])selected.The China Meteorological Data Sharing Service Center provided temperature data during the study period.In the two follow-ups,a total of 25,511 records(average age:first,64.57;second,65.80)were evaluated,including 10,604 males(41.57%).The inversely J-shaped associations between moving average temperatures(lag01–lag07)and FVC,FEV1,and PEF were observed,and the optimum temperatures at lag04 were 16.5C,18.7C,and 16.2C,respectively.At lag04,every 1C increase in temperature was associated with 14.07 mL,9.78 mL,and 62.72 mL/s increase in FVC,FEV1,and PEF in the lowtemperature zone(<the optimum temperatures),whereas 5.72 mL,2.01 mL,and 11.64 mL/s decrease in the high-temperature zone(the optimum temperatures),respectively(all P<0.05).We observed significant effect modifications of gender,age,body mass index,body surface area,smoking status,drinking status,and physical activity on the associations(all Pmodification<0.05).Non-optimal temperatures may cause lung function decline.Several individual characters and lifestyles have effect modification on the temperature effects.

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 and influence factors of self-medication in Chinese middle-aged and elderly people: evidence from 2011, 2013 and 2015 CHARLS panel data

Self-medication is an increasingly frequent phenomenon worldwide and has an important influence on health.In this study,we analyzed the self-medication prevalence rate in Chinese middle-aged and elderly people,and explored the influence factors.The data from China Health and Retirement Longitudinal Study(CHARLS)in 2011,2013 and 2015 were used.Self-medication prevalence was calculated as the number of whole people divided by the number of people taking self-medication.The influence factors of self-medication were analyzed by panel data random effect model.We excluded observations with missing values in our analysis,leaving 16 962,17 876 and 19 572 observations in 2011,2013 and 2015,respectively.The average 3-year self-medication prevalence was 45.52%.Moreover,11.70%of respondents practiced self-medication with prescription medicine in 2011,2013 and 2015.Respondents living in non-rural areas(P=0.009)and western region(P=0.000)took more self-medication.Self-medication was a common phenomenon among middle-aged and elderly population in China.The government should strengthen the guidance for the middle-aged and elderly people who took more self-medication,such as those living in urban and western region.

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.

The Association between Interpersonal Relationship and Erectile Dysfunction of Middle-Aged and Elderly Men in a Rural Area of Zhejiang,China

Objective:To explore the association between interpersonal relationship and erectile dysfunction(ED)of middle-aged and elderly men.Methods:A population-based cross-sectional research was conducted in the rural area of Jiashan County,Zhejiang Province,in 2016.Middle-aged and elderly men(aged 40-80)were selected as study participants.The face-to-face questionnaire was collected,including basic information,lifestyles,interpersonal relationship,and sexual function.The interpersonal relationship was evaluated based on marital relationship,neighborhood relationship,and relatives/friends relationship.According to the International index of erectile function,the study participants were divided into ED group(mild ED,moderate-to-severe ED),and non-ED group.Correlations were evaluated between interpersonal relationship indices and the prevalence or the severity of ED.Potential confounders were adjusted by the logistical regression model.Results:There were 674 study participants with average age of 60.4±8.5 years,and 489 ED patients with prevalence of 72.6%.With age increasing,the prevalence and the severity of ED increased significantly.The men who could get help from spouse when an emergency occurred or who were more cared about by their neighbors had lower ED risk,and odds ratios(ORs)(95%confidence intervals[CIs])were 0.23(0.13-0.42)and 0.58(0.46-0.75),respectively.After the adjustment of the covariates(age,education degree,household income,smoking,and drinking),the ORs(95%CIs)were 0.29(0.14-0.60)and 0.54(0.39-0.74),respectively.Good marital relationship and good neighborhood relationship were associated with a less severity of ED.

Study on Prevention and Treatment of Kidney Deficiency and Bone Mineral Loss in Middle-Aged and Elderly Female Diabetes Patients

In this study, 48 cases of middle-aged and elderly female diabetes patients were dividedrandomly into two groups, and treated separately by western medicine alone ( glibenclamide) in group A, andby traditional Chinese medicine (herbs that replenish the Kidney and activate blood circulation ) and gliben-clamide in group B. Before treatment, the patients of both groups had elevated glycosylated hemoglobin(HbAlc) and fast blood glucose (FBG) levels, decreased serum estradiol (E2 ) and testosterone/estradiol(E2/T) ratio, and the loss of bone mineral (elevated urinary calcium,phosphorus levels) . Most ot the pa-tients in the two groups had the symptoms of soreness and weakness of the loins and knees, general weak-ness ,dizziness,decreased sexual libido , palpitation and frequent urination , etc. These symptoms in traditionalChinese medicine belong to the deficiency of the Kidney. After treatment in both groups. the patients' serumHbAlc, FBG, and urinary Beta-2-microglobulin (B2M) got reduced, the concentration of serum sex hormone(E2 , E2/T ratio) elevated, and the elimination of urinary calcium, phosphorus levels cut down. But , the ther-apeutic effect in group B is apparently better than that in group A. The symptoms of deficiency of the Kidneywas apparently improved in group B. So, The authors think the medicinal herbs(reinforcing Kidney and acti-vating blood circulation) have an important role in the prevention and treatment of the 'Kidney deficiency'and bone mineral loss in middle-aged and elderly female diabetes patients.
