    ABSTRACT: Objective: Frailty is a significant healthcare challenge in China. However, the relationship between frailty and the prognosis of older people in China remains unclear. The present study aimed to evaluate the prevalence of frailty and determine if the frailty index, a comprehensive geriatric assessment, was associated with the prognosis of older people in a Chinese population. Methods: Data were drawn from the Beijing Longitudinal Study of Aging, a representative cohort study with an 8-year follow-up. Evaluations based on the use of the frailty index were performed in a cohort of 1808 people aged 60 years and over residing in Beijing urban and rural areas. The initial survey was conducted in 2004, with follow-up surveys at 3, 5, and 8 years. Mortality data for all individuals were collected and analyzed. Results: The frailty index and the age of individuals showed the same trend, with a higher frailty index expected as age increased. Respondents with the same frailty index level differed across factors such as sex and location. Male individuals, rural dwellers, and older individuals showed higher frailty rates than female individuals, urban dwellers, and younger individuals. Conclusions: Frailty is a condition associated with problems across multiple physiological systems. The frailty index increases with age, and may be a significant tool for evaluation of the prognosis of older people in China.

    ABSTRACT: Background: Sensory impairment affects an increasing number of elderly adults, with a negative psychological impact. Our objective was to examine the associations of visual and hearing impairment with subjective well-being (SWB), an important psychological concept defined by life satisfaction [LS], positive affect [PA], negative affect [NA], and affect balance [AB] among long-lived individuals (LLIs) over 95 years of age. Methods: Data on 442 LLIs from the Rugao longevity cohort, a population-based study in Rugao, China, were analyzed. Graded classifications of visual and hearing impairment (none, mild, moderate, and severe) were constructed from self-reported items. Bivariate correlation and multiple regression analysis were performed to test the associations. Results: Approximately 66.1% and 87.3% of the subjects reported varying degrees of visual and hearing impairment. Following the degree of vision impairment, LS, PA, and AB decreased linearly, whereas NA increased linearly (all p for trend<0.05). Vision was significantly related to LS (r=0.238, p<0.001), PA (r=0.142, p<0.01), NA (r=-0.157, p<0.001), and AB (r=0.206, p<0.001). After adjustment for multiple variables including functional ability, an important factor of SWB, the associations of vision impairment with LS, NA, and AB, while diminished, still existed. Conclusions: Visual impairment, but not hearing impairment, was independently associated with low SWB among LLIs, and functional ability may play a mediating role in the observed relationship. The findings indicate that rehabilitation targeted for those with reduced vision and functioning in long-lived populations may be important for promoting well-being and quality of life.

    ABSTRACT: Background: For older individuals with multimorbidity the appropriateness of prescribing preventive medicines remains a challenge. Objective: Investigate the prevalence and temporal trends in utilisation of preventive medicines in older New Zealanders from 2005 to 2013 stratified according to age, sex, ethnicity and district health board domicile. Methods: A repeated cross-sectional analysis was conducted on pharmaceutical dispensing data for all individuals' ≥65 years. Variable medication possession ratio (VMPR) was used to measure adherence. Prescribing of low-dose aspirin, clopidogrel, dipyridamole, warfarin, dabigatran, statins and bisphosphonates with a VMPR≥0.8 were examined. Results: Aspirin utilisation increased by 19.55% (95% CI: 19.39-19.70), clopidogrel by 2.93% (95% CI: 2.88-2.97) and dipyridamole decreased by 0.65% (95% CI: -0.70 to -0.59). Utilisation of aspirin with clopidogrel increased by 1.78% (95% CI: 1.74-1.81) and aspirin with dipyridamole increased by 0.54% (95% CI: 0.50-0.58%).Warfarin decreased by 0.87% (95% CI: -0.96 to -0.78) and dabigatran increased by 0.65% (95% CI: 0.60-0.70). Statins increased by 7.0% (95% CI: 6.82-7.18) and bisphosphonates decreased by 2.37% (95% CI: -2.44 to -2.30). Aspirin, clopidogrel, dabigatran and statins utilisation showed a greater increase in males. Interestingly, clopidogrel, warfarin and statins use increased in older adults aged 85+ compared to the younger age groups (65-84 years). Conclusion: To our knowledge, this is the first study investigating the prevalence and trends of preventive medicines use in older people in New Zealand. This study may facilitate further research to examine the appropriateness of prescribing these medicines in older people with multimorbidity.

    ABSTRACT: Background: Abnormal hematogram components could predict future metabolic syndrome (MetS) and diabetes. However, there was no study focusing on the subgroups of the elderly. In this ten-year longitudinal study, we investigated the association between hematogram components, future MetS and diabetes in the elderly. Methods: Subjects above 65 years were divided into three groups by age (young old: ≧65 and <75, old-old: ≧75 and <85 and oldest-old ≧85).By using multiple logistic regression, the hazard ratio (HR) of higher hemoglobin (Hb), white blood cell count (WBCC) and platelet (PLT) to have future MetS and diabetes were evaluated. Results: There were 15169 subjects in the young-old group, 3536 in the old-old group and 202 in the oldest-old group, respectively. After 10 years follow-up, only higher WBCC and Hb levels (>5.0×10(3), 15g/dL, respectively) was correlated to future MetS in young-old men (adjusted HR: 1.242, 1.166, respectively). In addition, higher Hb (>13.7g/dL) was originally associated with future MetS in young-old and old-old women but failed in adjusted HR. Moreover, the PLT did not correlate with any of the endpoints. Finally, higher chances of diabetes could be noted with higher WBCC in both men and women (adjusted HR: 1.404, 1.206, respectively). Conclusions: The associations between hematogram and future MetS were different in each subgroup of the elderly. Higher WBCC and Hb levels could predict future MetS in young-old men. Moreover, Higher WBCC is positively correlated with future diabetes in both young-old men and women.

    ABSTRACT: Background: The association between cerebrovascular atherosclerosis and Alzheimer's disease (AD) has been examined in many cross-sectional studies; however, there are few data regarding the role of cerebrovascular atherosclerosis on the longitudinal course of cognitive decline in AD. The aim of this study was to examine the progression of cognitive function in AD patients with cerebrovascular atherosclerosis compared to those without atherosclerosis over a two-year period. Methods: Forty-seven AD patients with cerebrovascular atherosclerosis and 81 AD patients without atherosclerosis were assessed for cognitive function at the time of diagnosis and again at follow-up after two years. The cognitive functions were evaluated by neuropsychological tests including mini-mental state examination (MMSE) and clinical dementia scale (CDR). Results: Repeated-measures multivariate analyses showed that there was a significant group-by-time interactions for the temporal changes of the MMSE and CDR between the two groups. The group-by-time interactions remained significant when the atherosclerotic patients were sub-classified into either an extracranial stenosis (EC) group or an intracranial stenosis(IC) group. Comparing either the EC or IC group with the non-atherosclerosis group, there were no main effects by time or group alone, but there were significant group-by-time interactions for the MMSE and CDR. Conclusions: Cognitive function worsened more in terms of progressive impairment in AD patients with cerebrovascular atherosclerosis compared to AD patients without cerebrovascular atherosclerosis, regardless of whether the atherosclerosis was extracranial or intracranial.

    ABSTRACT: Multiple tender points are common in the population and, in studies of mid-life adults, are strongly associated with high levels of psychological distress. Whether this relationship occurs in older adults is unclear. This cross-sectional study investigated whether high levels of psychological distress would be associated with a high tender point count and whether the relationship would be moderated by age. Three thousand three hundred and seventy-nine individuals were mailed a questionnaire which included the Hospital Anxiety and Depression (HAD) scale, the Pain Catastrophising Scale (PCS), the Brief Illness Perception Questionnaire (Brief IPQ), and the Pittsburgh Sleep Quality Index (PSQI). A random sample of approximately 10% of subjects who returned the questionnaire undertook a physical assessment, including a manual tender point count assessment. A total of 2385 (71%) subjects completed the questionnaire, of whom 798 (33%) were invited to take part in the physical assessment and 290 (12%) participated. Of the 290 participants the median age was 64 years (range 34-97) and 63% were female. The median HAD score was 9 (IQR 5-14) and the median number of tender points was 3 (range 0-7). Increasing HAD score was positively and significantly associated with tender point count, but this relationship was not moderated by age. In a final multivariable model, sex, HAD score and PSQI score were independent predictors of multiple tender points. Psychological distress was associated with multiple tender points independent of age. Psychological distress and trouble sleeping were important, potentially modifiable factors associated with the outcome.

    ABSTRACT: Objective: This study aimed to evaluate the association between reproductive variables and metabolic syndrome (MetS) among Chinese community elderly women. Methods: We conducted a cross-sectional study in a Beijing urban district. A two-stage stratified clustering sampling method was used and 1251 elderly women were included. Results: The prevalence of MetS was 65.1% in this population. Women with MetS had younger menarche age, a greater number of years after menopause, higher gravidity and parity. The prevalence of MetS showed an increasing trend for tertiles of years after menopause (p=0.002) and number of children (p<0.001), while decreasing trend for menarche age (p=0.021). Logistic regression showed ORs of age at menarche, years after menopause and number of children for MetS were 0.94, 1.40, and 1.36 for second and 0.63, 1.58, and 1.75 for last tertiles. Conclusion: There is strong association between reproductive variables and higher risk of MetS. Simple information on timing of menarche and menopause could help identify women who may have higher risk of getting MetS and take early action to prevent related chronic diseases.

    ABSTRACT: Objective: The purpose of this study was to compare the effect of two different approaches of dual-task training and executive training on pattern of gait in older adults with balance impairment. Methods: Thirty older adults with the mean age of 73.8 participated in the study. They scored 52 or less on the Berg Balance Scale (BBS), and walked with a self-selected gait speed of 1.1m/s or less. Participants were randomly assigned to one of the three groups: experimental group one (cognitive dual-task (CDT) training) that focused on gait performance under dual task condition; experimental group two (executive function (EF) training) who underwent 3 types of training on working memory, inhibition, speed of processing; and a control group. Subjects walked 10m, under single-task and dual-task (DT) conditions where kinematics parameters were recorded. Participants in experimental groups received 45-min training sessions, 3 times a week for 8 weeks. The data obtained was analyzed using repeated measure at a criterion p-value of 0.05. Results: The results showed that after training, changes of walking speed, length of stride and step, times of stride, step, single support, and double support, were significant at p<0.05. Asymmetry index in walking with dual task condition increased significantly, but after training asymmetry in DT condition decreased significantly in EF group. Conclusions: Both training groups showed improvements in gait parameters in the post test compared with that in the control group; however, in EF training group, symmetry of limbs and inter-coordination, improved more than that in CDT group.

    ABSTRACT: Objective: The issue of non-response in dementia epidemiological studies, which may result in the underestimation of the prevalence of dementia, has attracted little attention. We aimed to explore the causes and related factors of non-response in a dementia survey among Chinese veterans. Methods: A two-phase, cross-sectional study investigated the prevalence of dementia and mild cognitive impairment in Chinese veterans aged ≥60 years. We collected the socio-demographic data and prior medical history, evaluated the health status of veterans and their caregivers, assessed the cognitive status of veterans, and evaluated the care burden of caregivers by Caregiver Burden Inventory (CBI). Results: Of 9676 eligible participants, 525 (5.4%) veterans in phase 1 and 1706 (35.0%) veterans among 4875 veterans in phase 2 did not respond. Illness, hospitalization and death accounted for 63.0% and 75.5% non-response in phases 1 and 2, respectively. Non-participation in social activities, self-perceived poor health status, worsened health changes, self-reported need for life care, and history of hearing loss or glaucoma independently predicted non-response in phase 1 or 2. The heavy care burden, suggested by the higher CBI scores and self-reported health deterioration of the primary caregivers, predicted non-response in phase 1 or 2. Conclusions: The negative factors from both the participants and their caregivers independently predicted the non-response in the dementia study in an older population. Preventative strategies from the perspectives of the participants and caregivers should be developed to improve the response rates in both phases in a cross-sectional study.

    ABSTRACT: Objective: This analysis assessed the extent to which: (1) wrist accelerometer measures were associated with difficulty performing specific activities of daily living and instrumental activities of daily living and (2) these measures contributed important information about disability beyond a typical self-reported vigorous activity frequency question. Methods: We used data from the National Social Life, Health and Aging Project (NSHAP) accelerometry sub-study (n=738). Activity was assessed using two wrist-accelerometer measures assessed over 3 days (routine activity expressed as mean count/15s epoch during wake time, and immobile time expressed as the proportion of wake time spent immobile), and self-reported average vigorous activity frequency. The association between routine activity, immobile time and difficulty performing fourteen activities of daily living (ADLs) and instrumental activities of daily living (IADLs) plus two summary measures (any ADL or IADL difficulty), was assessed using logistic regression models, with and without controlling for self-reported vigorous activity. Results: Self-reported activity was mildly correlated with routine activity (r=0.27) and immobile time (r=-0.21). Routine activity, immobile time, and self-reported vigorous activity were significantly associated with twelve, ten, and fourteen disability measures, respectively. After controlling for self-reported activity, significant associations remained between routine activity and eight disabilities, and immobile time and six disabilities. Conclusion: Wrist accelerometry measures were associated with many ADL and IADL disabilities among older adults. Wrist acclerometry in older adults may be useful to help assess disability risks and set individualized physical activity targets.

    ABSTRACT: Background: Age and gender effects on muscle tone and mechanical properties have not been studied using hand-held myometric technology. Monitoring changes in muscle properties with ageing in community settings may provide a valuable assessment tool for detecting those at risk of premature decline and sarcopenia. Objective: This study aimed to provide objective data on the effects of ageing and gender on muscle tone and mechanical properties of quadriceps (rectus femoris) and biceps brachii muscles. Methods: In a comparative study of 123 healthy males and females (aged 18-90 years; n=61 aged 18-35; n=62 aged 65-90) muscle tone, elasticity and stiffness were measured using the MyotonPRO device. Results: Stiffness was greater and elasticity lower in older adults for BB and RF (p<0.001). Tone was significantly greater in older adults for BB but not for RF when data for males and females were combined (p=0.28). There were no gender differences for BB in either age group. In RF, males had greater stiffness (young males 292 vs females 233N/m; older males 328 vs females 311N/m) and tone (young 16.4 vs 13.6Hz; older 16.7 vs 14.9Hz). Elasticity in RF was lower in young males than females but did not differ between the older groups (both males and females log decrement 1.6). Conclusions: Stiffness and tone increased with ageing and elasticity decreased. These findings have implications for detecting frailty using a novel biomarker. Age and gender differences are important to consider when assessing effects of pathological conditions on muscle properties in older people.
