RESUMEN
BACKGROUND AND AIM: Cardiovascular diseases (CVD) is a major threat to public health, while cardiorespiratory fitness (CRF) is a key predictor of chronic disease. Given this, the purpose of this study was to investigate the relationship between estimated CRF (eCRF) and CVD in middle-aged and elderly Chinese people. METHODS AND RESULTS: The China Health and Retirement Longitudinal Study (CHARLS) with 4761 individuals were included in analysis. Participants were divided into three groups according to eCRF quantile in sex subgroups. Cox proportional hazards regression models were used to explore the correlation of eCRF with CVD (stroke or cardiac events). In total, 4761 participants were included in this cohort study (2500 [52.51%] women). During a 7-year follow-up from 2011 to 2018, 796 CVDs (268 Strokes and 588 cardiac events) were recorded. In multivariable-adjusted analyses, for per 1 SD increase of eCRF, the age-adjusted risk of CVD was reduced by about 18% (HR = 0.82; 95% CI, 0.72-0.93) in men, and was reduced by about 29% (HR = 0.71; 95% CI, 0.62-0.81) in women. Similar associations were also found between eCRF and stroke and cardiac events. Both subgroup and interaction analyses showed that the interaction of age had a statistically significant effect on CVD risk. CONCLUSION: ECRF was inversely associated with CVD risk (stroke or cardiac events) in both men and women. Remarkable sex and age differences exist in the effectiveness of increasing eCRF to reduce the risk of CVD. As a potential, efficient and cost-effective risk prediction tool, eCRF deserves further attention and wide application.
RESUMEN
The rapid development of digital technology has radically changed people's lives. Simultaneously, as the population is rapidly aging, academic research is focusing on the use of Internet technology to improve middle-aged and older people's health, particularly owing to the popularity of mobile networks, which has further increased the population's accessibility to the Internet. However, related studies have not yet reached a consensus. Herein, empirical analysis of the influence of mobile Internet use on the subjective health and chronic disease status of individuals in their Middle Ages and above was conducted utilizing ordered logit, propensity score matching (PSM), and ordered probit models with data from the 2020 China Health and Retirement Longitudinal Study. The study aimed to provide a theoretical basis and reference for exploring technological advances to empower the development of a healthy Chinese population and to advance the process of healthy aging. The health of middle-aged and older adults mobile Internet users was greatly improved, according to our findings. Further, the use of mobile Internet by these persons resulted in improvements to both their self-assessed health and the state of their chronic diseases. As per the findings of the heterogeneity analysis, the impact of mobile Internet use was shown to be more pronounced on the well-being of middle-aged persons aged 45-60 years compared to those aged ≥ 60 years. Further, the endogeneity test revealed that the PSM model could better eliminate bias in sample selection. The results suggest that the estimates are more robust after eliminating endogeneity, and that failure to disentangle sample selectivity bias would overestimate not only the facilitating effect of mobile Internet use on the self-assessed health impacts of middle-aged and older adults, but also the ameliorating effect of mobile Internet use on the chronic diseases of middle-aged and older adults. The results of the mechanistic analysis suggest that social engagement is an important mediating mechanism between mobile Internet use and the health of middle-aged and older adults. This implies that mobile Internet use increases opportunities for social participation among middle-aged and older adults, thereby improving their health.

BACKGROUND: With the continuing impact of the aging population, medical-elderly care integrated institutions, as a way to bear the pressure of medical and elderly care, effectively ensure the quality of life of the elderly in their later years. OBJECTIVES: To explore the preferences of medical-elderly care integrated institutions among Chinese middle-aged and older people and to provide a reference for establishing elderly-oriented development of medical-elderly care integrated institutions. METHODS: In this study, a discrete choice experiment (DCE) was used to investigate the preferences of people aged 45 years and older in medical-elderly care integrated institutions in China from October 20, 2022, to November 10, 2022. A mixed logit regression model was used to analyze the DCE data. Participants' willingness to pay for each attribute was also calculated. RESULTS: Data from 420 participants who provided valid responses were included in the analysis. In terms of the choice preference, moderate service quality (vs. poor service quality: ß = 1.707, p < 0.001, 95% CI 1.343 ~ 2.071) and high medical technology level (vs. low medical technology level: ß = 1.535, p < 0.001, 95% CI 1.240 ~ 1.830) were the most important attributes to middle-aged and older people, followed by monthly cost, environmental facilities, the convenience of transportation, and entertainment activities. Regarding the willingness to pay, participants were more willing to pay for service quality and medical technology level than for other attributes. They were willing to pay $3156 and $2838 more for "poor service quality" and "low medical technology level," respectively, to receive "moderate service quality " (p = 0.007, 95% CI 963 ~ 5349) and "high medical technology level" (p = 0.005, 95% CI 852 ~ 4824). CONCLUSIONS: The state should attach great importance to the development of medical-elderly care integrated services industry, actively optimize the model of the medical-elderly care integrated service, improve the facilities, and create a healthy environment. At the same time, give full play to the role of medical insurance, long-term care insurance, and commercial insurance, so as to improve the comprehensive quality of life of the elderly. PUBLIC CONTRIBUTION: The design of the experimental selection was guided by 10 experts in the field, 5 Chinese government officials, and interviews and focus group discussions, without whose participation this study would not have been possible.
RESUMEN
Background and Objectives: The older members of a population might experience unmet medical needs, despite desiring medical care due to activity limitations driven by their perception of aging. This study conducted a cross-sectional analysis of the association between perceived activity restriction (PAR) due to people's own perception of aging and unmet medical needs (UMN) in late middle-aged and older Koreans based on the Korean National Health and Nutrition Examination Survey (KNHANES). Materials and Methods: The 2016-2020 KNHANES was used to analyze a total of 2008 participants among groups aged 45 years or older by applying individual weights imposed from the raw data. The independent variable of PAR was assessed using self-reported questionnaires based on the global activity limitation indicator. Also, the dependent variable of UMN, referring to the state in which a patient's medical care or service was insufficient, inadequate, or lacking, was assessed using a single question. After excluding missing values, the data on 2008 individuals were analyzed using a chi-square test, weighted logistic regression, and a stratified analysis of gender, age, and the presence of chronic illnesses. Results: The group that experienced PAR had an OR 2.13 higher (odds ratio [OR]: 2.13; 95% confidence interval [CI]: 1.27-3.56) to present UMN than the group that did not experience PAR. Furthermore, the results of the stratified analysis indicated that, in the group of female participants with chronic illness and in the group of elderly people, experiencing PAR was associated with a higher experience of UMN. Conclusions: There was a close association between PAR and UMN. In particular, when PAR occurred in the group of female participants with chronic illness and in the group of elderly people, the incidence rate of UMN was also found to be high. This finding highlights the need for policies and institutional measures to reduce UMN within vulnerable groups with an increased risk of medical inaccessibility due to activity restriction.

BACKGROUND: This study aims to identify the current status and factors influencing self-management of knee discomfort in middle-aged and elderly people in China. METHODS: A stratified multistage cluster sampling method was used to select participants from communities in China from January 15 to May 31, 2020. A cross-sectional survey was conducted using the general information questionnaire and the Knee Joint Discomfort Self-management Scale. Univariate analysis and a generalized linear model were used to analyze the factors influencing self-management. RESULTS: The prevalence of knee discomfort was 77%. Moderate to severe discomfort accounted for 30.5%. The average item score of self-management in 9640 participants was 1.98 ± 0.76. The highest and lowest levels were: 'daily life management' and 'information management'. Gender, ethnicity, education level, economic source, chronic disease, knee pain in the past month, and the degree of self-reported knee discomfort were significant predictors of self-management. CONCLUSION: The self-management of knee discomfort in middle-aged and elderly people is poor, and the degree of discomfort is a significant predictor. Healthcare providers should consider socioeconomic demographic and clinical characteristics to help these individuals improve their self-management skills. Attention should also be given to improving their ability to access health information and making them aware of disease risks.

OBJECTIVES: This study assessed the correlation between middle-aged and elderly fraud victimhood's experiences of being defrauded (EOBD) and depressive symptoms. STUDY DESIGN: This was a prospective study. METHODS: Data from China Health and Retirement Longitudinal Study 2018 (N = 15,322, mean age = 60.80 years) were used. Logistic regression models were used to identify the association between EOBD and depressive symptoms. Independent analyses were used to examine the association between different types of the fraud and depressive symptoms. RESULTS: Among the middle-aged and elderly people, 9.37% of them have EOBD, and it was significantly associated with depressive symptoms. Among those with EOBD, fundraising fraud (3.72%) and fraudulent pyramid scheme and sales fraud (22.4%) were significantly associated with depressive symptoms, whereas telecommunication fraud (73.88%) had a limited role in inducing depressive symptoms in victimhood. CONCLUSION: This study suggested that the government should make further efforts to prevent fraud, pay more attention to the mental health of the middle-aged and elderly victimhood, and provide timely psychological assistance to reduce the secondary harm caused by fraud.

OBJECTIVE: To investigate the dietary consumption of branched-chain amino acids(BCAAs)intake status of middle-aged and elderly people 50 years and older in China, and to analyze the distribution differences between different ages, genders and regions. METHODS: The research sample was derived from the 2015 Chinese adult chronic disease and nutrition monitoring data. The survey adopts the stratified multi-stage cluster random sampling method, and selects 298 monitoring points from 31 provinces(autonomous regions and municipalities), a total of 44 218 people aged 50 years and over were sampled. Condiment weighing method, 24-hour dietary review method, and weighing method were used to obtain individual dietary data, and the dietary BCAAs intake of middle-aged and elderly people was calculated based on the Chinese Food Composition Table. RESULTS: In 2015, the dietary BCAAs of middle-aged and elderly people in China accounted for 45.1% of leucine, 29.8% of valine and 25.1% of isoleucine. The top six dietary sources were cereals, red meat, vegetables, fish and seafood, beans and eggs. There were differences in the intake of three branched-chain amino acids(F=1926.67, P<0.01), the intake of leucine was greater than that of valine, and the intake of valine was greater than isoleucine. There were statistically significant differences in dietary BCAAs intake between different age groups, genders, urban and rural areas and regions(P<0.01), among which men were greater than women(t=12.89, P<0.01), and the south was greater than the north(t=-6.36, P<0.01), the eastern part was larger than the central part, and the central part was larger than the western part(F=82.42, P<0.01). The intake of BCAAs decreased with the increase of age groups(F=22.69, P<0.01), and there was no significant difference in age groups over 70 years old. The dietary intake of BCAAs was higher in the eastern coastal areas and Inner Mongolia, Xinjiang and Tibet. CONCLUSION: There were gender, age and geographical differences in dietary BCAAs intake among middle-aged and elderly people in China, and the contribution of various foods to dietary BCAAs was also different.

This cross-sectional study aimed to analyse the relationship between Tai Chi exercise habits and depression tendency and sleep quality in people practicing Tai Chi in Chengdu, China. A total of 1352 Tai Chi practitioners aged 50-79 years old were divided into six groups according to age and gender for Tai Chi exercise habits, depression tendency and sleep quality. The frequency of weekly Tai Chi practice and duration of single Tai Chi practice have a significant positive correlation with the exercise years. For female subjects who had long-term Tai Chi exercise, depression decreased with the duration and weekly frequency of a single exercise. Tai Chi exercise habits reduced sleep disturbance scores (in the male group aged 60-69 years old, exercise years, r = -0.242, p = 0.004) and sleep duration (in the male and female group aged 70-79 years old, duration of single Tai Chi practice, r = -0.334, p = 0.035; r = -0.235, p = 0.029), suggesting that long-term Tai Chi exercise may reduce the trend of poor sleep quality due to increased ageing.
RESUMEN
BACKGROUND: Dyslipidemia is a key factor causing cardio cerebrovascular diseases, and the total cholesterol (TC) is an important lipid indicator among them. Studies have shown that environmental factors have a strong association with TC levels. Previous studies only focused on the seasonal variation of TC level and the short-term effects of some environmental factors on TC level over time, and few studies explored the geographical distribution of TC level and quantified the impact of environmental factors in space. METHODS: Based on blood test data which was from China Health and Retirement Longitudinal Study (Charls) database, this study selected the TC level test data of middle-aged and elderly people in China in 2011 and 2015, and collected data from 665 meteorological stations and 1496 air pollutant monitoring stations in China. After pretreatment, the spatial distribution map of TC level was prepared and the regional statistics were made. GeoDetector and geographically weighted regression (GWR) were used to measure the relationship between environmental factors and TC level. RESULTS: The TC level of middle-aged and elderly in China was higher in females than in males, and higher in urban areas than in rural areas, showing a clustered distribution. The high values were mainly in South China, Southwest China and North China. Temperature, humidity, PM10 and PM2.5 were significant environmental factors affecting TC level of middle-aged and elderly people. The impact of pollutants was more severe in northern China, and TC level in southern China was mainly affected by meteorological factors. CONCLUSIONS: There were gender and urban-rural differences in TC levels among the middle-aged and elderly population in China, showing aggregation in geographical distribution. Meteorological factors and air pollutants may be very important control factors, and their influencing mechanism needs further study.

OBJECTIVE: Sleep plays an important role in the health and well-being of middle aged and elderly people, and social capital may be one of the important factors for sleep disorders. This study aimed to understand the relationship between social capital and sleep disorders in a unique region of China -Tibet that generally has the disadvantaged economic status compared to other parts of China. METHODS: The study was based on Tibetan data from The China Multi-Ethnic Cohort (CMEC) and was conducted from May 2018 to September 2019. A total of 3194 Tibetans aged > 50 were selected from the community population by multi-stage stratified cluster sampling. Social capital was measured using two validated health-related social capital scales, family/community and society.. Sleep disorders were measured as the presence of disorders of initiating and maintaining sleep, early morning awakening, or daytime dysfunction. Logistic regression models were applied to examine the association between social capital and sleep disorders. RESULTS: 39.9% (1271/3194) of the participants had sleep disorders. In addition, after controlling for all potential variables, family social capital was significantly negatively associated with sleep disorders (OR = 0.95, P < 0.05), while community and society social capital was not associated with sleep disorders. Then, when we did all the sex-stratified analyses, the significant association between social capital and sleep disorders was found only in women (OR = 0.94, P < 0.05), while no association was found in males; neither males nor females showed any association with community and society social capital. CONCLUSION: Our study would help to better understand the extent of health inequality in China, and guide future interventions, strategies and policies to promote sleep quality in low-income areas, taking into account both the role of Tibetan specific cultural traditions, lifestyles and religious beliefs in social capital and the gender differences in social capital.

OBJECTIVE: To explore the association between sleep duration and mild cognitive impairment(MCI) in people aged 55 and above in 4 provinces of China. METHODS: A stratified multi-stage cluster random sampling method was adopted. From May to August 2018 in 32 survey districts and counties in 4 provinces of Hebei, Zhejiang, Shaanxi, and Hunan, 5334 55-year-old and older persons who met the inclusion criteria were randomly selected. Among them, there were 2362 males and 2972 females, with an average age of(67. 43±7. 48) years. A questionnaire survey was conducted to collect their basic information, lifestyle, disease history, sleep duration, etc. MCI were screened based on the Montreal cognitive assessment(MoCA). Multivariate Logistic regression was used to analyze the association between sleep duration and MCI. RESULTS: 16. 76% of them slept for less than 7. 0 hours, 19. 10% of the middle-aged and elderly people slept for 9 hours or more, and 36. 24% of them were found to be MCI. After adjusted the area, age, gender, education level, work status, family monthly income per capita, smoking, drinking, physical activity, meditation time, depression, hypertension, diabetes, myocardial infarction and stroke, the result of multivariate Logistic regression analysis shown that, compared with 7. 0-7. 9 hours of sleep, the risk of MCI among middle-aged and elderly people over 55 years old with <6. 0 hours and 8. 0-8. 9 hours of sleep were 1. 417 times(95%CI 1. 012-1. 984)and 1. 191 times(95%CI 1. 001-1. 418)of the former, respectively, and the differences were statistically significant(P<0. 05). The risk of men suffering from MCI for sleep duration <6. 0 hours was 2. 083 times(95%CI 1. 145-3. 789)that of the former, and the risk of women suffering from MCI for sleep duration ≥ 9. 0 hours was 1. 741 times(95%CI 1. 301-2. 331)that of MCI. The differences are statistically significant(P<0. 05). CONCLUSION: Shorter or longer sleep time is an important factor independently related to MCI. Insufficient sleep in men and longer sleep time in women can increase the risk of MCI.

OBJECTIVE: To investigate the potential association between multimorbidity and the handgrip strength of middle-aged and older adults. METHODS: The baseline (2011) and second-round follow-up (2015) data of China Health and Retirement Longitudinal Study (CHARLS) were used. Adults≥40 were selected as the subjects of the study. Variables incorporated in the study included handgrip strength, chronic disease prevalence, demographic variables, and health behavior variables. Generalized estimating equations were used to analyze the longitudinal association between handgrip strength and multimorbidity. RESULTS: A total of 28 368 middle-aged and older adults were included in the baseline and follow-up samples, with an average age of (59.1±9.7) years old, the oldest being 96 while the youngest being 40. Among them, 6 239 were male, accounting for 47.3%. In the second-round follow-up, 9 186 baseline respondents and 5 994 new respondents were covered, reaching a total of 15 180 respondents. Compared with the baseline, a higher proportion of the second-round follow-up respondents were female ( P=0.033) and were older ( P<0.001). From the baseline to the second-round follow-up, Q1, the lowest grip strength category, increased from 23.4% to 26.6%, while Q4, the highest grip strength category, decreased from 26.5% to 21.2%. The prevalence of having more than three chronic diseases increased from 18.2% to 24.2% and the prevalence of having more than five chronic diseases increased from 3.3% to 6.2%. After adjusting for confounding variables, the interaction items of handgrip strength and time showed statistical significance. After stratification by gender, the interaction items of male handgrip strength and follow-up time were statistically significant in both models ( P<0.05). The marginal effect graph of the interactive item showed that the multimorbidity prevalence of respondents with lower handgrip levels grew faster with age. Individual effect analysis showed that the correlation between handgrip strength and multimorbidity was not statistically significant at baseline, but the follow-up done four years afterwards showed statistical significant correlation between handgrip strength and multimorbidity. CONCLUSION: Respondents with lower baseline handgrip strength are associated with increasingly higher risk of multimorbidity over time. Handgrip strength can be used as an effective screening tool for middle-aged and older adults in China to identify those at higher risks of multimorbidity of chronic diseases.

OBJECTIVE: To understand the status of depression and its influencing factors in the middle-aged and older adult populations aged 45 and above in China on the basis of data from the 2018 China Family Panel Studies (CFPS), and to provide empirical evidence for the improvement of the mental health of the middle-aged and older adults and the alleviation of their depressive symptoms. METHODS: The source of the research data was the 2018 CFPS. The Center for Epidemiologic Studies Depression Scale (CES-D) was used to assess the prevalence of depression. A two-level two-category unconditional logistics regression method was used to analyze the influencing factors of the prevalence of depressive symptoms. RESULTS: The 80th percentile interval score of depression score was used as the critical value, and the detection rate of depressive symptoms was 23.61%. It was more likely for women to suffer from depressive symptoms than it was for men. Widowed individuals were at an even higher risk for having depression. The more education one had, the lower the possibility of developing depression. Middle-aged and older adults in rural areas were more likely to suffer from depression. Middle-aged and older adults with chronic diseases and self-rated poor health were at higher risk of depression. Sleep time is a protective factor that suppressed symptoms. After controlling the above-mentioned individual-level factors, middle-aged and older adults in coastal and economically developed areas were less likely to suffer from depression than those from inland and economically underdeveloped areas did. CONCLUSION: The health departments concerned should focus on the depressive symptoms of women, widowed individuals, and middle-aged and older adults with chronic diseases. In rural areas and underdeveloped inland regions, the state should invest more health resources in the prevention and improvement of depression among middle-aged and older adults.

BACKGROUND: In light of the health poverty alleviation policy, we explore whether the New Rural Cooperative Medical System (NRCMS) has effectively reduced the economic burden of medical expenses on rural middle-aged and elderly people and other impoverished vulnerable groups. The study aims to provide evidence that can be used to improve the medical insurance system. METHODS: Data were obtained from the 2015 China Health and Retirement Longitudinal Study (CHARLS). The method of calculating the catastrophic health expenditure (CHE) and impoverishment by medical expense (IME) was adopted from the World Health Organization (WHO). The treatment effect model was used to identify the determinants of CHE for rural middle-aged and elderly people. RESULTS: The incidence of CHE in rural China for middle-aged and elderly people is 21.8%, and the IME is 8.0%. The households that had enrolled in the NRCMS suffered higher CHE (21.9%) and IME (8.0%), than those that had not enrolled (CHE: 20.6% and IME: 7.7%). The NRCMS did not provide sufficient economic protection from CHE for households with three or more chronic diseases, inpatients, or households with members aged over 65 years. Key risk factors for the CHE included education levels, households with inpatients, households with members aged over 65 years, and households with disabilities. CONCLUSIONS: Although the NRCMS has reduced barriers to the usage of household health services by reducing people's out-of-pocket payments, it has not effectively reduced the risk of these households falling into poverty. Our research identifies the characteristics of vulnerable groups that the NRCMS does not provide enough support for, and which puts them at a greater risk of falling into poverty due to health impoverishment.

Backgroud and Purpose: Hypertension has been regarded as one of the most common chronic diseases reported in different studies, and handgrip strength is a good indicatorof anindividual's overall health. However, few studies have concentrated on investigating the relationship between hypertension and handgrip strength, especially for the middle-aged and elderly population in the community. Therefore, the purpose of this study was to explore the association of handgrip strength with the risk of hypertension.Methods: A cross-sectional study was conducted using a multi-instrument questionnaire. A total of 1152 participants aged 45 and older were included in this study. Handgrip strength, social-demographiccharacteristics, behavioral lifestyle and health-related variables were collected. Binary logistic regression was employed to analyse the relationship.Results: Handgrip strength was positively related to the risk of hypertension. Binary logistic regression models revealed that the increase of handgrip strength was significantly associated with the reduction of hypertension risk in female after adjusting forsocial-demographic characteristics, behavioral lifestyle and health-related variables (OR [95%CI] =0.265 [0.089-0.787]). In addition, after stratifying by age groups, the significant association was still existing in 60-74 years and ≥75 years of female groups, respectively(OR [95%CI] =0.158 [0.032-0.779]; (OR [95%CI] =0.009 [0.000-0.409]). No significant associations were observed in male after adjusting variables.Conclusion: stronger handgrip strength was association with the lower risk ofhypertension for the elderly female population.Abbreviations: BMI: body mass index; DBP: diastolic blood pressure; HC: hip circumference; SBP, systolic blood pressure; WC: waist circumference; WHC: hip-waist relation.

Objectives: To investigate the severity and effect on quality of life (QOL) of various types of pain in healthy volunteers.Methods: A total of 384 subjects (male: 158, female: 226, average age: 63 years) were included in a prospective cohort study (Yakumo study). Shoulder pain, low back pain (LBP), sciatica, knee pain, and the American Shoulder and Elbow Surgeons (ASES) shoulder score were evaluated with SF-36.Results: The prevalence of shoulder pain, LBP, sciatica, and knee pain was 42%, 44%, 16%, and 48%, respectively, with similar severities of pain. Shoulder pain visual analogue scale (VAS) and ASES shoulder scores were significantly correlated with SF-36 domains. Subjects with poor physical QOL had significantly higher VAS scores for all pain types and a lower ASES shoulder score. Shoulder pain VAS was also significantly related to poor mental QOL. Multivariate regression analysis adjusted for age and gender showed that shoulder pain VAS (OR: 1.25, p < .05) and 10-m gait speed (OR: 1.82, p < .05) were significant independent risk factors for poor physical QOL.Conclusion: Only shoulder pain of similar severity to other pain and shoulder complaints impacted on both physical and mental QOL. The severity of shoulder pain was an independent risk factor for poor physical QOL.

Objectives: Locomotive syndrome (LS) in middle-aged and elderly people has a high risk of a need for nursing care. The goal of the study was to examine predictors of LS in a prospective longitudinal study. Methods: The subjects were 205 people (87 males, 118 females) aged >40 years who underwent physical examinations and completed health questionnaires in health checkups in the Yakumo study in 2011 and 2016. LS was defined as ≥16 on the 25-Question Geriatric Locomotive Function Scale (GLFS-25). Subjects with LS in 2011 were excluded. Associations of all variables with the GLFS-25 score were analyzed using univariate and multivariate analyses. A receiver operating characteristic (ROC) curve for each physical measurement test was constructed to determine the best threshold value. Results: The subjects were divided into LS (n = 21) and non-LS (n = 184) groups, based on the 2016 checkup. In multivariate analysis, GLFS-25 (odds ratio [OR] = 1.437; p < 0.01), one-leg standing time (OR= 1.043, p < 0.05), and back muscle strength (OR =0.961, p <0.05) were significant predictors of LS. ROC analyses gave GLFS-25 scores of 6.2 and 6.8, one-leg standing times of 26.8 and 23.3 s, and back muscle strengths of 75.2 and 49.5 kg as thresholds for prediction of future LS in males and females, respectively. Conclusions: GLFS-25 score, one-leg standing time, and back muscle strength were identified as significant risk factors for LS in community-dwelling people, and threshold values were determined for these factors in a longitudinal study. For elderly people, these indicators could be predictors of locomotive syndrome, and may have validity for assessment of improvement of physical abilities through muscle training and body balance training.

Objective: To explore the relationship between weight change and the changes in blood pressure, blood glucose and blood lipid profiles in middle-aged and elderly Chinese people. Methods: All participants were from the Dongfeng-Tongji cohort study. The study included 16 606 middle-aged and elderly Chinese people with complete information in the baseline survey in 2008 and the first follow-up survey in 2013. We collected the data on demographic characteristics, lifestyle, history of diseases and medication, and the results of medical health examinations, including height, weight, blood pressure, fasting blood glucose and lipid profiles. We divided the weight change into five groups, moderate or above weight loss (<-8.0%), slight weight loss (-8.0%, -3.1%), weight maintenance (-3.0%, 3.0%), slight weight increased (3.1%, 8.0%), and moderate or above weight increased (>8.0%). Generalized linear regression model was used to analyze the relationship between weight change and the changes in systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting blood glucose (FBG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and triglyceride (TG). Subgroup analyses were used to explore the influences of gender, age and baseline BMI level on the relationship between weight change and the above-mentioned metabolic indicators. Results: The average age of participants in baseline survey was (62.19±7.28) years with a range of 45 to 89 years. During the five-year period, there were 18.86% (2 633), 28.03% (4 655), 35.87% (5 956), 13.96% (2 319), 6.28% (1 043) people with moderate or above weight loss, slight weight loss, weight maintenance, slight weight increased, and moderate or above weight increased, respectively. Regression analyses showed that body weight change were positively correlated with changes in SBP, DBP, FBG, TC, LDL-C and TG, and negatively correlated with change in HDL-C (all linear trend P values were<0.05); As every 10% of weight changed, the ß (95%CI) of changes in SBP (mmHg) (1 mmHg=0.133 kPa), DBP (mmHg), FBG (mmol/L), TC (mmol/L), LDL-C (mmol/L), HDL-C (mmol/L) and TG (mmol/L) were 4.94 (4.32, 5.55), 2.50 (2.11, 2.88), 0.05 (0.02, 0.08), 0.13 (0.11, 0.16), 0.14 (0.12, 0.16), -0.05 (-0.07, -0.04) and 0.16 (0.14, 0.18), respectively. Furthermore, subgroup analyses showed that weight change can lead to greater changes in blood pressure in older and overweight or obesity elderly people (all P for interaction<0.05). Conclusion: Weight loss was beneficial for middle-aged and elderly people to improve the blood pressure, blood glucose and blood lipid profiles, regardless of the weight at the baseline, while weight gain was not.

OBJECTIVE: To know the prevalence of low body weight among middleaged and elderly people in general rural areas of China and investigate the influence factors. METHODS: A total of 25 464 participants who were 45 years old and above from2010-2012 China National Nutrition and Health Surveillance as subjects to investigate the prevalence of low body weight. For 545 low body weight participants, we performed a1ⶠ2 case-control study to investigate the influence factors. The content of survey included3-condecutive days-24-hour dietary recall, physical examinations, physical activity and social economic factor. RESULTS: The prevalence of low body weight among middle-aged and elderly people was 5. 27%, 5. 52% for male and 5. 05% for female. The prevalence of low body weight increased with the age( P < 0. 01). The daily intake of energy, total proteins, high quality proteins, fat and fruits were lower in low body weight than normal body weight among middle-aged and elderly people( P < 0. 01), however, the consumption of smoking and alcohol were higher in low body weight than normal body weight( P < 0. 01). Multivariate conditional Logistic regression analysis showed that the daily intake of total proteins, vegetables and fruits were protective factors and unhealthy lifestyle such as smoking were risk factors among low body weight people. CONCLUSION: The prevalence of low body weight at a higher level among middle-aged and elderly people in general rural areas of China. It is necessary to promote the middle-aged and elderly people to increase the consumption of high-protein foods, vegetables and fruits, quit smoking and control drinking.

BACKGROUND AND OBJECTIVE: A meta-analysis was conducted to evaluate the impact of resistance training on pro-inflammatory cytokines c-reactive protein (CRP), interleukin 6 (IL 6), and tumor necrosis factor- α (TNF- α) in middle-aged and elderly individuals. METHODS: The retrieval period for the Web of Science and other large electronic databases is set by default to March 2022. Both included and excluded researchers are independent examination literature on the impact of resistance exercise on markers of inflammation in the elderly. The physical medical care Evidence Database scale (Physical Therapy Evidence Database, PEDro) was used to evaluate the research quality, and Revmen 5.3 was used to end the index analysis. RESULTS: After a total of four rounds of elimination, 12 items were eventually included. The total sample size for the research was 388 persons. Resistance training substantially reduced CRP levels in middle-aged and older individuals, with SMD = -0.56 and 95 % confidence interval ([-0.78, -0.34], P < 0.00001, correspondingly. Resistance training can successfully lower IL6 concentrations in middle-aged and older adults, although the combined impact is not substantial. SMD = -0.25, 95 % CI [-0.54, 0.04]; P = 0.09. TNF- concentrations did not alter significantly following resistance exercise in middle-aged and older adults. The overall effect was SMD = -0.07, with a 95 % confidence interval [-0.37, 0.23], while P = 0.64. CONCLUSION: Resistance training reduces CRP, IL6, and TNF-α levels among middle-aged and elderly people. However, it has no significant anti-inflammatory effects on TNF-α. Resistance exercise at a moderate level for 3 times / week with a duration of 6-12 weeks or 16-32 weeks, significantly reduced CRP levels. This work contributing to exploring the resistance training program for the elderly to reduce inflammatory markers, and further, providing suggestions for the elderly to participate in resistance training and reduce the concentration of inflammatory markers.
