ABSTRACT
O Brasil vive uma transição demográfica que favorece o aparecimento e desenvolvimento de doenças crônicas não transmissíveis (DCNT). Em um cenário em que as DCNT estão entre as principais causas de mortes, reforçar a importância de uma alimentação saudável é imprescindível, e medidas preventivas tomam lugar de destaque. Pensando nisso, foram realizadas 11 intervenções de educação alimentar e nutricional em um grupo de atividade física intergeracional, com o objetivo de promover autonomia alimentar. O estudo contou com 25 participantes, na faixa etária de 37 a 83 anos, sendo a maior incidência de 61 a 69 anos (n=12) e predominância de pessoas do gênero feminino (92%). Os parâmetros para avaliar o grupo foram os feedbacks das(os) participantes e o grau de adesão, no qual houve aumento significativo ao longo do período interventivo. Destaca-se a importância de ampliar a abordagem dos hábitos alimentares saudáveis em diversos ambientes, sendo os grupos de atividades físicas um campo fértil, que requer a adaptação da linguagem e formato das atividades, considerando o nível de escolaridade das(os) participantes. Assim, a educação alimentar e nutricional pode ser usada como ferramenta efetiva para a promoção da saúde, a prevenção e o tratamento de DCNT.
Brazil is undergoing a demographic transition that favors the onset and development of chronic non-communicable diseases (NCDs). In a scenario where NCDs feature among the main causes of death, reinforcing the importance of healthy eating is essential and preventive measures should take place. Consequently, eleven Food and Nutritional Education interventions were conducted with an intergenerational physical activity group to promote food autonomy. A total of 25 individuals aged 37 to 83 years participated in the study, with the highest prevalence of 61 to 69 years (n=12) and women (92%). Evaluation parameters were participant feedback and the degree of adherence, which increased significantly over the interventional period. Results highlight the importance of broadening the approach to healthy eating habits in various environments, with physical activity groups being a fertile setting which requires adapting language and the format of activities according to participants' schooling level. Nutritional Food Education can be used as an effective tool for health promotion, prevention and treatment of NCDs.

ABSTRACT
Resumo Fundamento A doença cardiovascular (DCV) é uma série de doenças que afetam o coração ou os vasos sanguíneos. Objetivos Avaliar a relação entre os níveis de pressão arterial (PA) definidos pelo American College of Cardiology/American Heart Association (ACC/AHA) de 2017 diretriz e risco de DCV/doença cardiovascular aterosclerótica (DCVA) para pessoas de meia-idade e idosos na China. Métodos Um total de 6.644 pessoas de meia-idade e idosas do Estudo Longitudinal de Saúde e Aposentadoria da China CHARLS (China Health and Retirement Longitudinal Study) foram finalmente incluídas. De acordo com a diretriz ACC/AHA de 2017, todos os indivíduos foram divididos em quatro grupos: PA normal, PA elevada, hipertensão estágio 1 e hipertensão estágio 2. O desfecho deste estudo foi considerado o risco de DCV e DCVA. Modelos de regressão COX univariados e multivariados foram adotados para examinar a relação da classificação de PA ACC/AHA de 2017 com o risco de DCV. Modelos de regressão logística univariada e multivariada foram utilizados para investigar a associação entre os níveis de PA e o risco de DCVA. Foram realizadas análises de subgrupos baseadas em idade, sexo e uso de medicamentos anti-hipertensivos. P<0,05 foi aceito como estatisticamente significativo. Resultados Após ajustar todas as covariáveis, em comparação com pacientes de meia-idade e idosos com PA normal, descobrimos que pacientes com hipertensão estágio 1/2 estavam associados a um maior risco de DCV, separadamente. Simultaneamente, também observamos uma associação positiva entre indivíduos com PA elevada, hipertensão estágio 1, hipertensão estágio 2 e maior risco de DCVA no modelo totalmente ajustado. O resultado das análises de subgrupos indicou que a relação entre hipertensão estágio 1/2 e DCV/DCVA alta foi robusta em diferentes idades e sexos, e participantes sem uso de medicamentos anti-hipertensivos. Conclusão A classificação da PA de acordo com as diretrizes de PA da ACC/AHA de 2017 pode ser aplicada à população chinesa.
Abstract Background Cardiovascular disease (CVD) is a series of diseases affecting the heart or blood vessels. Objectives To assess the relationship between blood pressure (BP) levels defined by the 2017 American College of Cardiology/American Heart Association (ACC/AHA) guideline and CVD/atherosclerotic cardiovascular disease (ASCVD) risk for middle-aged and elderly people in China. Methods A total of 6,644 middle-aged and elderly people from the China Health and Retirement Longitudinal Study (CHARLS) were finally included. According to the 2017 ACC/AHA guideline, all subjects were divided into four groups: normal BP, elevated BP, stage 1 hypertension, and stage 2 hypertension. The outcome of this study was considered as the risk of CVD and ASCVD. Univariate and multivariate COX regression models were adopted to examine the relationship of the 2017 ACC/AHA BP classification with the risk of CVD. Univariate and multivariate logistic regression models were used to investigate the association between BP levels and ASCVD risk. Subgroup analyses based on age, gender, and use of antihypertensive drugs were performed. P<0.05 was accepted as statistically significant. Results After adjusting all covariates, compared to middle-aged and elderly patients with normal BP, we found that patients with stage 1/2 hypertension were associated with a higher risk of CVD, separately. Simultaneously, we also observed a positive association between individuals with elevated BP, stage 1 hypertension, stage 2 hypertension, and higher ASCVD risk in the fully adjusted model. The result of subgroup analyses implied that the relationship between stage 1/2 hypertension and CVD/ high ASCVD was robust in different ages and genders, and participants without using antihypertensive drugs. Conclusion BP classification under the 2017 ACC/AHA BP guidelines may apply to the Chinese population.
ABSTRACT
<b>Objective</b> To evaluate the effect of glycogen synthase kinase 3β (GSK3β) on hypoxia/reoxygenation (H/R)-induced injury of senescent renal tubular epithelial cell (RTEC) in aged mice and its regulatory mechanism. <b>Methods</b> RTEC were divided into the Young group (young RTEC with normal growth), Old group (aged RTEC induced by Etoposide), Old+Ad-shNC+H/R group [aged RTEC induced by Etoposide and then transfected with adenovirus negative control (Ad-shNC) for H/R treatment], and Old+Ad-shGSK3β+H/R group (aged RTEC induced by Etoposide and then transfected with short-hairpin RNA-expressing adenovirus with targeted silencing GSK3β for H/R treatment), respectively. Apoptosis level and mitochondrial reactive oxygen species level were detected by flow cytometry. Calcium ion level was determined by immunofluorescence staining. The expression and phosphorylation levels of GSK3β, mitochondria-associated endoplasmic reticulum membrane (MAM)-related proteins of inositol 1,4,5-trisphosphate receptor1 (ITPR1), voltage dependent anion-selective channel 1(VDAC1) and glucose-regulated protein 75 (GRP75) were detected by Western blot. The interaction between GSK3β and MAM-related proteins was analyzed by immunoprecipitation. <b>Results</b> Compared with the Young group, the apoptosis, mitochondrial reactive oxygen species and mitochondrial calcium ion levels were higher in the Old group. Compared with the Old group, the apoptosis, mitochondrial reactive oxygen species and mitochondrial calcium ion levels were higher in the Old+Ad-shNC+H/R group. Compared with the Old+Ad-shNC+H/R group, the apoptosis, mitochondrial reactive oxygen species and mitochondrial calcium ion levels were lower in the Old+Ad-shGSK3β+H/R group, and the differences were statistically significant (all <i>P</i><0.05). Compared with the Young group, the expression levels of ITPR1, GRP75 and GSK3β proteins were up-regulated, the phosphorylation levels of ITPR1 and GRP75 were increased, whereas the total protein and phosphorylation levels of VDAC1 were decreased in the Old group. Compared with the Old group, the expression level of GSK3β protein was unchanged, the total protein and phosphorylation levels of ITPR1 and GRP75 were increased, the expression level of total VDAC1 protein remained unchanged and the phosphorylation level was increased in the Old+Ad-shNC+H/R group. Compared with the Old+Ad-shNC+H/R group, the expression level of GSK3β protein was decreased, the expression levels of total ITPR1, GRP75 and VDAC1 proteins were unchanged, whereas the phosphorylation levels were decreased in the Old+Ad-shGSK3β+H/R group. Immunoprecipitation showed that GSK3β could interact with ITPR1, GRP75 and VDAC1 proteins. <b>Conclusions</b> The expression level of GSK3β is up-regulated in senescent RTEC. Down-regulating GSK3β expression may reduce the phosphorylation level of ITPR1-GRP75-VDAC1 complex, constrain the overload of mitochondrial calcium ion, protect mitochondrial function and mitigate cell damage during reperfusion.
ABSTRACT
Objective To explore the mediating role of cognitive function in the association between literacy level and depressive symptoms in middle-aged and elderly people in China. Methods Using the fourth national follow-up data of the China Health and Elderly Care Tracking Survey 2018, 8 124 middle-aged and elderly people aged 45 years and above were included as the study subjects. The PROCESS 4.0 program was used to test the mediating effect of cognitive function between literacy level and depressive symptoms, and the Bootstrap method was used for the mediator variable validation. Results The detection rate of depressive symptoms among middle-aged and elderly people in China was 38.10%. After controlling for gender, place of residence, marital status, smoking, alcohol consumption, and exercise, literacy level was a negative predictor of depressive symptoms in middle-aged and elderly people (β =－0.480, t =－11.248, P<0.001). Cognitive function accounted for 58.75% of the amount of mediating effect between literacy level and depressive symptoms. Conclusion Literacy level and cognitive function are associated with depressive symptoms in middle-aged and elderly people. Literacy level can influence depressive symptoms directly or indirectly through the mediation of cognitive dysfunction.
ABSTRACT
Objective:To investigate the self-care contribution and binary coping level of spouse caregivers for middle-aged and young stroke patients and explore the relationship between the two, in order to improve the quality of self-care contribution of spouse caregivers to middle-aged and young stroke patients.Methods:A cross-sectional survey was conducted among 200 middle-aged and young stroke patients ′ spouse caregivers in the People ′s Hospital of Xinjiang Uygur Autonomous Region from January to June 2023 by the general data questionnaire, the Caregiver Contribution to Self-care of Stroke Patient Scale, the Dyadic Coping Inventory. The correlation between self-care contributions and binary coping strategies of spousal caregivers was analyzed, and the factors that affect their self-care contributions were screened. Results:Finally, 192 middle-aged and young stroke patients ′ spouse caregivers were included, including 70 males and 122 females, aged 18-59 years old. The total score of self-care contribution of spousal caregivers of middle-aged and young stroke patients was (75.43 ± 6.80) points, and the total score of binary coping was (117.12 ± 9.59) points, both of which were positively correlated ( r=0.691, P<0.05). Hierarchical regression analysis showed that after controlling for the influence of general data, binary coping could explain 28.4% variation in the self-care contribution of spouse caregivers of middle-aged and young stroke patients ( P<0.05). Conclusions:The duality coping level positively predicts the quality of spouse caregivers ′ self-care contribution to middle-aged and young stroke patients. Medical staff should assess the dual coping level of middle-aged and young stroke patients and their spouses, and carry out targeted dual intervention measures to improve the quality of caregivers' contribution to stroke patients ′ self-care.
ABSTRACT
Objective:To explore the influencing factors of dietary behavior change of young and middle-aged patients after percutaneous coronary intervention (PCI) from the perspective of the family system, so as to provide the basis for home dietary intervention of patients.Methods:Using the phenomenological research method, 32 young and middle-aged PCI patients and their family members from Department of Cardiology, Xuanwu Hospital, Capital Medical University were interviewed in a semi-structured in-depth way by purposive sampling method from May to October 2022, and the data were analyzed by Colaizzi 7-step analysis method.Results:Among the 32 surveyed individuals, there were 17 males and 15 females, aged 22-61 years old. Two themes of dietary behavior change facilitators and barriers of young and middle-aged patients after PCI were extracted. The facilitators included six subthemes: behavioral autonomy, adaptive change, small family size, motivation for family responsibility, internal family resources, and external family resources. The barriers included five subthemes: bad learned habits, special physical conditions, lack of nutritional literacy, passive dietary environment, and limited economic level.Conclusions:Dietary behavior changes in young and middle-aged patients after PCI were affected by individual and family factors in the family. Medical staff should establish a family-centered dietary management model and integrate the advantages of family resources to give patients targeted individualized nutrition intervention.
ABSTRACT
Objective To analyze the current oral health status of middle-aged and elderly people in Wuhan,and to provide clinical evidence for preventing and promoting oral health among middle-aged and elderly people.Methods The data was col-lected from the annual health examination data system of Wuhan,which included 1994 patients aged 45～95.According to the World Health Organization(WHO)"Basic Methods of Oral Health Survey"(5 th edition),the data of caries,periodontal disease,dentition defect,dentition loss and denture restoration was mainly studied.Statistical methods such as Chi-square test and vari-ance analysis were used for data analysis.Results Among the 1994 subjects,1613 people(80.89％)were male and 218 people(10.93％)were older than 75 years old.The average numbers of caries and teeth loss were 2.68 and 2.03,respectively.The mean number of caries and tooth loss increased with age.The mean numbers of caries and tooth loss in 45～,55～,65～,75～,and 85～95 years old groups were 0.98 and 0.54,1.82 and 1.39,3.21 and 2.48,7.65 and 6.04,12.65 and 9.91,respective-ly.The difference among different age groups was statistically significant(P＜0.01).The proportion of restoration of teeth loss was also elevated with the increase of age(P＜0.01),and the difference of community periodontal index(CPI)among different age groups was also statistically significant(P＜0.01).The proportion of people in CPI1 group(shallow periodontal pocket)was decreased with the increase of age,while the proportion of people in CPI2 group(deep periodontal pocket)was increased with the increase of age(P＜0.01).Conclusion The overall oral health examination results of middle-aged and elderly people in Wuhan shows that the oral health status is slightly better when compared with the result of urban area in the 4th National Oral Health Examination.But caries,periodontal disease,tooth loss and unrepaired dentures are still serious in the elderly population.It is necessary to improve the prevention awareness of oral diseases in the elderly through regular oral examination,timely detection and treatment.At the same time,attention should be paid to dental restoration in the elderly population to improve the quality of life.
ABSTRACT
BACKGROUND:Middle-aged and elderly women have a high risk of osteoporosis,and chronic diseases increase the risk of osteoporosis.Low bone mass is a risk stage before the onset of osteoporosis.There are a small amount of relevant reports on the difference of fracture risk and the tangent value of diagnostic indicators in the population with common chronic diseases. OBJECTIVE:Through the analysis of fracture risk of middle-aged and elderly women with different chronic diseases,to investigate the correlation between obesity,hypertension,hyperlipemia,diabetes,arteriosclerosis and bone mineral density and identify the cut-off value of low bone mass index,thereby providing reference for the prevention and treatment of osteoporosis. METHODS:A total of 203 cases of female adults aged 45-70 years were divided into normal group and chronic disease group.The calcaneal bone density was measured by using an ultrasonic bone densitometer.Brachial-ankle pulse wave velocity was tested by using an arteriosclerotic instrument.Blood sugar and blood lipid were tested by using an automatic biochemical analyzer.Body mass index,fat mass and muscle mass were measured by using a body composition analyzer. RESULTS AND CONCLUSION:There were significant differences in body mass index and fracture risk coefficient of women aged 61-70 years and bone strength of women aged 51-60 years and 61-70 years compared with those aged＜50 years(P＜0.05).The fracture risk of diabetes group was significantly higher than that of the other groups,while the fracture risk of arteriosclerosis group was significantly higher than that of normal group and obesity group(P＜0.05).Bone mineral density was negatively correlated with age,left vascular elasticity,right vascular elasticity and triglyceride level,but positively correlated with body mass index(P＜0.05).The area under the receiver operating characteristic curve of body mass density and the above indexes was 0.5-0.7,and the corresponding tangents of low body mass density were 55.5 years old(age),756.0 cm/s(left vascular elasticity),789.0 cm/s(right vascular elasticity),1.115 mmol/L(triglyceride level)and 22.35 kg/m2(body mass index).To conclude,diabetes and arteriosclerosis increase the risk of fracture in middle-aged and elderly women.Body mass index,vascular elasticity and triglyceride level have a certain early diagnostic value in predicting low bone mass in women.
ABSTRACT
Objective:To analyze the impact of individual and regional level socioeconomic characteristics on the mental health of middle-aged and older adults based on data from the China Health and Retirement Longitudinal Study.Methods:This study was a cohort study. Using the data from the China Health and Retirement Longitudinal Study, subjects without depression were screened in the baseline survey, the depression status of the selected subjects was tracked and observed for seven years. Descriptive statistical analysis, multivariate logistic analysis, joint analysis were used to analyze the influence of factors such as gender, personal annual income, education level, urban and rural areas, and eastern, central, and western regions on the risk of depression among middle-aged and elderly people.Results:The 7-year follow-up results showed that the prevalence of depression symptoms in the study subjects was 42.24%; compared with men, women′s risk of developing depression symptoms was significantly increased ( OR=1.782); compared with junior college education and above, middle school (including technical secondary school), primary and lower education levels had a significantly increased risk of developing depression symptoms ( OR=1.476, 2.134); compared with annual income of more than 10 000 yuan, subjects with an annual income of 10 000 yuan or below had significantly increased risk of developing depression symptoms ( OR=1.251). At the same time, compared with the urban area, the risk of developing depression symptoms was significantly increased in the rural areas ( OR=1.389). Compared with the eastern area, the risk of developing depression symptoms was significantly higher in the central and western areas ( OR=1.342, 1.730). The joint analysis results showed that compared with high-income and high-education men, low-income low-education women, high-income low-education women, low-income middle-education women, and high-income middle-education women were at the top four odd ratios for developing depression symptoms ( OR=5.050, 3.662, 3.047, 2.641); compared with men in eastern cities, rural women in the west, rural women in the middle, women in the western cities, and rural women in the east ranked the first four odd ratios for developing depression symptoms ( OR=4.286, 3.216, 2.642, 2.158). Conclusion:Socioeconomic factors at the individual and regional levels have a significant impact on the risk of developing depressive symptoms in middle-aged and older adults, and mental health management of middle-aged and older adults with low socioeconomic status should be strengthened.
ABSTRACT
Objective:To investigate the relationship between thyroid-stimulating hormone(TSH) levels and 10-year mortality in women aged 40 years and older.Methods:Residents aged 40 and over in urban areas of Guiyang City who participated in the " Epidemiological Study of Cancer Risk in Patients with Type 2 Diabetes in China(REACTION)" were followed up in 2011. Finally, 5 614 people were enrolled, and the baseline general information, physical examination and TSH detection were carried out. The average follow-up was(9.77±1.55) years, and the treatment and death of thyroid-related diseases were recorded. The Cox proportional hazards model was used to analyze the relationship between TSH level and 10-year mortality in middle-aged and elderly women, and plotting survival time curves(Kaplan-Meier curves) to study the association between elevated TSH levels and lifespan in subjects under 65 years old. Results:The multivariate Cox proportional hazards model showed that compared with the normal group, after multivariate adjustment, the risk of death in the TSH increased group was decreased( HR=0.644, 95% CI 0.478-0.868, P<0.05); after stratifying the elevated TSH group, the risk of death was decreased in the slightly elevated TSH group( HR=0.566, 95% CI 0.405-0.791, P<0.001); the elevated TSH group was further stratified by age. In the group under 65 years old, compared to the normal group, the mildly elevated group showed a reduced risk of mortality( HR=0.429, 95% CI 0.245-0.751, P=0.003). In the group aged 65 and above, there were no statistically significant differences in mortality risk between the mildly elevated group, severely elevated group, and the normal group( P>0.05). In the group under 65 years old, the K-M curve indicated that the survival rate of the mildly elevated TSH group was significantly higher than that of the normal group( χ2=11.931, P=0.003), the difference was statistically significant. Conclusion:Mildly elevated TSH levels in women aged 40-65 years are associated with a reduced risk of all-cause death and longer lifespan.
ABSTRACT
ObjectiveThis study aims to explore risk factors for the development of major adverse cardiovascular and cerebrovascular events （MACCEs） in middle-aged and elderly patients with type 2 diabetes mellitus complicated with stable angina pectoris （T2DM-SAP） based on real-world clinical data in traditional Chinese medicine （TCM）， so as to develop a COX proportional risk prediction model and visualize the predicted results using a nomogram. MethodBased on the clinical scientific research information sharing system， the medical records of 586 T2DM-SAP patients （45-94 years old） were collected from January 2012 to December 2019， including age， gender， course of disease， major medical history， laboratory examination， tongue image， pulse image， TCM syndrome， and major treatment drugs. MACCE outcome indicators of patients were obtained by telephone follow-up and re-hospitalization records. The data was divided into a training set and a validation set according to 7∶3. In the training set， COX univariate analysis was used to determine the risk factors for MACCE in T2DM-SAP patients， and then variables were screened by forward-backward stepwise regression method， so as to establish a MACCE risk prediction model and construct a nomogram. The predictive efficacy of the model was reflected by the C-index， receiver operating characteristic （ROC） curve， calibration map， and clinical decision curve. ResultThe history of cerebrovascular disease ［Hazard ratio （HR）=1.983， 95% confidence interval （CI，1.314-2.993）］， low-density lipoprotein （LDL-C/mmol·L-1）≥4.1［HR=2.683， 95%CI（1.461-4.925）］， dull red tongue ［HR=1.955， 95%CI（1.273-3.002）］， dull purple tongue ［HR=4.214， 95%CI（2.017-8.803）］， white thick coating ［HR=3.030， 95%CI（1.634-9.293）］， thin and weak pulse ［HR=2.233， 95%CI（1.283-3.888）］， and syndrome of wind-phlegm blocking collaterals ［HR=2.007， 95%CI（1.179-3.418）］ were found to be risk factors in middle-aged and elderly T2DM-SAP patients. Insulin ［HR=0.604， 95%CI（0.399-0.914）］， glycosidase inhibitor ［HR=0.627， 95%CI（0.409-0.962）］， and TCM treatment ［HR=0.328， 95%CI（0.214-0.503）］ were protective factors in middle-aged and elderly T2DM-SAP patients. The prediction model was constructed based on the above risk factors. The C-index of the model was 0.818 （95% CI 0.777 -0.859） in the training set and 0.814 （95% CI 0.773-0.855） in the validation set， and the change of C-index over time was plotted. The AUC of patients for 5， 10， 15 years in the training set was 0.71， 0.67， and 0.61. The AUC of patients for 5， 10， and 15 years in the validation set was 0.60， 0.68， and 0.63， respectively. The calibration map and clinical decision curves of 5， 10， 15 years were drawn in the training set and the validation set， respectively. The model was well calibrated and clinically effective. ConclusionThe history of cerebrovascular disease， LDL， dull red tongue， dull purple tongue， white thick coating， thin and weak pulse， and syndrome of wind-phlegm blocking collaterals are risk factors for MACCE in middle-aged and elderly T2DM-SAP patients， and insulin， glycosidase inhibitors， TCM treatment are protective factors for MACCE in middle-aged and elderly T2DM-SAP patients. A clinical prediction model is established accordingly. This model has good discrimination， calibration degree， and clinical effectiveness and provides a scientific basis for the prevention and treatment of MACCE in middle-aged and elderly T2DM-SAP patients.
ABSTRACT
Objective@#To explore the factors affecting balance ability among middle-aged and elderly people with depressive symptoms, so as to provide the evidence for improving balance ability and prevention of falls.@*Methods@#Based on the 2015 database of China Health and Retirement Longitudinal Study (CHARLS), demographic information, lifestyle and health status were collected from people aged 45 years and older who scored 10 and more on the Self-rating Depression Scale or took antidepressants. The balance ability was assessed by semi-tandem and full-tandem stand tests, which was defined as meeting the standard when both tests were completed. Factors affecting the balance ability among middle-aged and elderly people with depressive symptoms were identified using a multivariable logistic regression model.@*Results@#Data were collected from 4 263 participants with an mean age of (60.73±8.53) years, including 1 748 males (41.00%) and 2 515 females (59.00%). There were 1 241 people failed to meet the standard of balance ability test, accounting for 29.11%. Multivariable logistic regression analysis showed that participants who were at ages of 65 years and older (OR=1.234, 95%CI: 1.071-1.421), were female (OR=1.422, 95%CI: 1.161-1.741), were physically disabled (OR=1.309, 95%CI: 1.127-1.521) and had physical pain (OR=1.170, 95%CI: 1.023-1.340) had higher risks of failing to meet the standard of balance ability test, while participants who took naps (OR=0.856, 95%CI: 0.748-0.980), never smoked (OR=0.641, 95%CI: 0.517-0.793) and had social activities (OR=0.864, 95%CI: 0.755-0.988) had lower risks of failing to meet the standard of balance ability test.@*Conclusion@#The balance ability among middle-aged and elderly people with depressive symptoms was associated with age, gender, napping, smoking, social activities, physical disability and physical pain.

ABSTRACT
Objective To explore the relationship between baseline urinary protein levels and the onset of chronic obstructive pulmonary disease (COPD). Methods A questionnaire survey, blood and urine sample collection, physical examination, and pulmonary function test were conducted among permanent residents over 40 years old in Pudong New Area, Shanghai. The subjects were divided into four groups based on the baseline urine albumin-to-creatinine ratio (ACR) quartiles (0~1.65 mg/g, 1.65~4.89 mg/g, 4.89~10.78 mg/g, and ≥10.78 mg/g). Cox regression analysis was used to explore the relationship between ACR levels and the incidence of COPD in middle-aged and elderly people. Results Among the 3 105 subjects, the median follow-up time was 3.212 years (P25~P75：3.102~3.473). 116 new cases of COPD were observed, with an incidence density of 10.423 per 1000 person-years. The incidence densities for COPD at four ACR levels were 7.922 per 1 000 person-years, 8.300 per 1 000 person-years , 11.419 per 1 000 person-years, and 13.843 per 1 000 person-years, respectively. Cox regression analysis revealed that as the ACR level increased, there was a rising trend in the incidence rate of COPD (χ2=4.396, P=0.036). After adjusting for gender, age, education level, occupational exposure to dust, history of childhood pneumonia, smoking, family history of COPD, central obesity, and hypertension, the risk of developing COPD was 2.499 times higher (95% CI: 1.460~4.276) for ACR levels ≥10.78 mg/g compared to the reference group with a baseline ACR level of 0~1.65 mg/g. Conclusion Elevated ACR levels in middle-aged and elderly population may increase the risk of COPD, and early monitoring of urine protein levels is beneficial for COPD prevention.
ABSTRACT
Objective@#To analyze the association between dietary inflammatory index (DII) and gallstone disease among middle-aged and elderly population, so as to provide the evidence for the prevention and control of gallstone disease.@*Methods@#Baseline survey data were collected from the Shanghai Women's Health Study (SWHS) and Shanghai Men's Health Study (SMHS), including demographic information, gallstone disease prevalence and dietary habits. DII was calculated using 29 kinds of food parameters associated with common inflammatory biomarkers and food intake data of residents. A multivariable logistic regression model was used to analyze the association between dietary inflammatory index and gallstone disease.@*Results@#A total of 132 312 individuals were included in the analysis. There were 59 627 males and 72 685 females. Among males, the median age was 53.07 (interquartile range, 9.73) years, 41 544 cases (69.67%) had an educational level of middle school, 4 463 cases (7.48%) had gallstone disease, and DII was -6.46 to 5.59. Among females, the median age was 50.27 (interquartile range, 9.05) years, 47 380 cases (65.19%) had an educational level of middle school, 8 090 cases (11.13%) had gallstone disease, and DII was -6.44 to 4.93. Multivariable logistic regression analysis showed that after adjusting for age, educational level, income level, smoking, alcohol consumption, tea consumption, physical activity and menopausal status (only for females), DII (OR=1.095, 95%CI: 1.002-1.196) was associated with an increased risk of gallston disease among males, but no statistically association was found among females (P>0.05).@*Conclusion@#DII might be associated with an increased risk of gallstone disease among middle-aged and elderly population.
ABSTRACT
Background Multimorbidity imposes a heavy burden on individuals, families, and society. There are relatively few studies exploring patterns of multimorbidity among middle-aged adults in China. Objective To explore the current status of multimorbidity, associated risk factors, and multimorbidity patterns among adults aged 45-64 years in China, so as to provide a scientific basis to prevent and control multimorbidity in China. Methods A total of 5494 adults aged 45-64 years from the Chinese Health and Nutrition Survey (CHNS) in 2018 were selected. Of these, 2494 (45.39%) were men and 3000 (54.61%) were women. The nine diseases included were hypertension, diabetes, dyslipidaemia, obesity, mild cognitive impairment (MCI), myocardial infarction, stroke, asthma, and tumor. The prevalence of each disease or multimorbidity was expressed as N (%). Comparisons of multimorbidity prevalence between different groups were performed using the χ2 test or Cochran-Armitage trend test. Association rule with the Apriori algorithm was used to explore the pattern of multimorbidity, with parameters set at a minimum conditional support of 3.00%, a minimum rule confidence of 50.00%, and a lift of >1.20. Logistic regression was used to evaluate the associations between selected risk factors and multimorbidity. Results In 2018, 37.44% of participants reported multimorbidity in 15 provinces of China. The prevalence of diseases in descending order was dyslipidaemia (39.99%), hypertension (39.48%), obesity (16.42%), MCI (14.47%), diabetes (14.16%), tumor (1.09%), stroke (1.04%), myocardial infarction (0.71%), and asthma (0.64%). A total of seven multimorbidity patterns were identified in this group. Obesity paired with hypertension, and diabetes paired with dyslipidemia were the two major patterns of multimorbidity in the general population and age or sex subgroups. The multimorbidity patterns of different populations were concentrated in the combination of obesity, hypertension, diabetes, and dyslipidemia. The risk of multimorbidity was lower in females than in males (OR=0.85, 95%CI: 0.75, 0.97). The multimorbidity risk was 1.56 times higher in the 55-64 years group than in the 45-54 years group (OR=1.56, 95%CI: 1.40, 1.75). Drinking in the past year increased the risk of multimorbidity by 25% (OR=1.25, 95%CI: 1.08, 1.45) compared to no alcohol comsumption in the past year. High and medium levels of physical activity were associated with a decreased OR (high: OR=0.74, 95%CI: 0.65, 0.85; medium: OR=0.81, 95%CI: 0.70, 0.93) with low level of physical activity as reference. Conclusion In 2018, there was a high prevalence rate of multimorbidity among middle-aged adults in China. The main multimorbidity patterns were obesity-hypertension and diabetes-dyslipidemia. Surveillance and interventions should be strengthened particularly for men, individuals with alcohol consumption or insufficient physical activity, and those with major multimorbidity patterns.
ABSTRACT
Background The number of persons with thyroid nodules has increased rapidly in recent years, and thyroid cancer caused by malignant nodules has become a key problem endangering the health of young and middle-aged groups in China. Objective To explore work and lifestyle influencing factors for developing thyroid cancer among young and middle-aged patients with thyroid nodules. Methods The subjects with thyroid nodules were reported by routine physical examines ordered at the Huadong Sanatorium. We conducted a 1∶4 matched case-control study in which 232 patients diagnosed with thyroid cancer from 2012 to 2022 were matched to 928 controls by gender and age (±5 years). A validated questionnaire was used to collect data on work and lifestyle behaviors. Univariate and multivariate logistic regression models were applied to explore potential relationships between selected factors (including environment, working hours, stress, diet, exercise, and mental health) and thyroid cancer. Spearman rank correlation was used to analyze the correlations between variables. Results The results of univariate logistic regression showed a history of thyroid cancer reported among first-degree relatives (OR=6.059, 95%CI: 1.007, 36.473), obesity (OR=1.973, 95%CI: 1.296, 3.004), noise and vibration exposure (OR=1.988, 95%CI: 1.143, 3.456), frequent stress (OR=2.093, 95%CI: 1.231, 3.559), frequent depression (OR=2.034, 95%CI: 1.048, 3.947), frequent anger (OR=1.791, 95%CI: 1.066, 3.012), frequent fried food diet (OR=1.535, 95%CI: 1.026, 2.297), and frequent fast food diet (OR=1.836, 95%CI: 1.048, 3.215) were risk factors for reporting thyroid cancer developing from thyroid nodules, while regular meals (OR=0.245, 95%CI: 0.061, 0.989) and frequent exercise (OR=0.571, 95%CI: 0.342, 0.952) were protective factors for reporting no thyroid cancer. The results of Spearman correlation analysis showed that body mass index was positively correlated with frequent fried food, fast food, and sugary beverage diets (r=0.123, 0.083, 0.077, P<0.01), and negatively correlated with frequent depression and anger (r=−0.090, −0.070, P<0.05). The results of multiple logistic regression found that a history of thyroid cancer reported among first-degree relatives (OR=6.712, 95%CI: 1.071, 42.066), obesity (OR=2.032, 95%CI: 1.321, 3.125), noise and vibration exposure (OR=1.991, 95%CI: 1.089, 3.637), and frequent stress (OR=2.468, 95%CI: 1.417, 4.300) were associated with an elevated risk of reporting thyroid cancer developing from thyroid nodules patients. Regular exercise (frequency≥3 times·week−1, > 30 min per episode) (OR=0.516, 95%CI: 0.300, 0.890) was associated with a lowered risk of reporting thyroid cancer. Conclusions Multiple risk factors associated with reporting thyroid cancer among young and middle-aged groups with thyroid nodules are identified, such as obesity, noise and vibration exposure, frequent stress, and lack of exercise.
ABSTRACT
ObjectiveTo explore the correlation between skeletal muscle mass and metabolic syndrome （MS） disease risk among middle-aged and elderly community residents in Urumqi， and to provide a theoretical basis for understanding the relationship between skeletal muscle mass and MS among middle-aged and elderly community residents in China. MethodsA total of 1 438 community residents ≥ 50 years old were selected as the research subjects from July 2018 to January 2019 in Urumqi. They were selected from a multi-ethnic natural population cohort in Xinjiang. Data were collected through questionnaires， physical examination， bioelectrical impedance analysis （BIA）， laboratory tests， etc. Skeletal muscle mass was evaluated using the limb skeletal muscle mass index （SMI） corrected for body weight； MS was defined as it at least includes three of the following： abdominal obesity， hypertension， hyperglycemia， high triglycerides and low high-density lipoprotein cholesterol. SMI was divided into four quantile arrays of Q1‒Q4. Trend χ2 test was applied to explore whether there was a correlation between SMI changes and MS. A multivariate logistic regression model was used to analyze whether there is a difference in the risk of MS between the higher SMI group （Q2， Q3， Q4） and the reference group Q1. ResultA total of 560 MS patients were detected in this study， with a prevalence rate of 38.94%. Among them， the prevalence rate of MS was 39.16% in males and 38.80% in females. The increase in male SMI grading level is not correlated with the prevalence of MS （trend P>0.05）； After adjusting for confounding factors （model 4）， the increase in SMI was still not related to the prevalence of MS （Ptrend=0.995）. There was no statistical difference in the risk of MS between the lowest quartile group Q1 and the highest quartile group Q4 （OR=1.01， 95%CI： 0.69‒1.78）. The prevalence of MS in women gradually decreased with the increase of SMI grading level （Ptrend<0.001）； After adjusting for confounding factors （model 4）， there was still a correlation between the increase of SMI and the prevalence of MS （Ptrend=0.005）. With the lowest quartile of SMI Q1 as the reference group， the risk of MS in Q2 （OR=0.63， 95%CI： 0.40‒1.00）， Q3 （OR=0.56， 95%CI： 0.34‒0.94）， Q4 （OR=0.42， 95%CI： 0.23‒0.76） decreased. ConclusionAn increase in skeletal muscle mass may be beneficial for preventing MS， especially among middle-aged and elderly female residents. Considering the intensification of aging in China and the close relationship between MS and related comorbidities， managing skeletal muscle mass may contribute to potential MS prevention.
ABSTRACT
Objective To conduct a retrospective cohort study on the influencing factors of poor prognosis of young and middle-aged patients with pulmonary tuberculosis. Methods Selecting 426 young and middle-aged patients who were diagnosed with pulmonary tuberculosis in our hospital from January to December 2018 as the research subjects. Collecting the social demography information of all patients and the information of potential factors affecting the prognosis (allergy history, smoking history, drinking history, BMI level, disease information, treatment information, etc.) and discussing the factors affecting the prognosis of young and middle-aged pulmonary tuberculosis patients and their effects. Results The average age of 426 patients was (41.93±5.17) years old, the average BMI of them was (21.97±3.15) kg/m2, and an average course of disease of them was (2.76±0.99) years. There was no significant difference in the basic sexual information between men and women. In this study, a total of 128 patients with poor prognosis were retrospectively followed up, including 90 males and 38 females. The detection rate of males was significantly higher than that of females (χ2=16.976, P2=18.850, P2=38.924, P2=127.207, P2=32.566, P2=16.715, P2=17.315, P2=16.976，P1 and P1 and P<0.05; Regular treatment still showed potential protective factors, with an HR of 0.408, P<0.05. Conclusion: Male, emaciated body type, disease course ≥ 5 years, smoking history, number of lung field lesions ≥ 3, presence of pulmonary cavities and comorbidities are potential risk factors, while regular treatment suggests potential protective factors. Conclusion More targeted disease control and management should be implemented for middle-aged and young patients with pulmonary tuberculosis based on the aforementioned influencing factors to improve their prognosis.
ABSTRACT
Objective @#To investigate the mediating effect of negative emotions on visual impairment and resilience among middle-aged and elderly populations, so as to provide insights into improving psychological health among middle-aged and elderly populations.@*Methods@#Demographic information, visual impairment, negative emotions and resilience in the residents at ages of 45 years and older were collected through the database of the Yushu Physical and Mental Health Survey carried out by Institute of Psychology of Chinese Academy of Sciences. Structural equation model was used to analyze the effects of visual impairment and resilience and the mediating role of negative emotions. @*Results@#Totally 2 997 middle-aged and elderly populations were enrolled, with the median age of 50.00 (interquartile range, 47.00) years. There were 1 320 males (44.04%) and 1 677 females (55.96%), 1 627 illiterate persons (54.29%), and 2 780 married persons (92.76%). The scores of visual impairment, negative emotions and resilience were (6.79±2.59), (6.35±3.05) and (33.38±10.41) points, respectively. The results of structural equation model analysis showed that after adjusting for age, gender, educational level and marital status, visual impairment had a direct negative positive effect on resilience, with a direct effect value of -0.157 (95%CI: -0.177 to -0.137), and visual impairment could also negatively affect residence through negative emotions, with a mediating effect value of -0.112 (95%CI: -0.126 to -0.104), and the mediating effect contributed 41.64% to the total effect.@*Conclusion@#visual impairment could reduce residence directly or indirectly through the mediating effect of negative emotions among middle-aged and elderly populations.
