Relationship of sleep quality, chronotype, and obstructive sleep apnea with migraine in the elderly population.

Disturbances of sleep have frequently been reported in individuals with migraine. On top of this, an elderly patient with migraine also suffers from sleep disturbances due to changes in physiologic and mental health associated with aging. This study aimed to compare several sleep factors, namely sleep quality, chronotype, and obstructive sleep apnea (OSA) risk, between elderly people with and without migraine. This was amulticenter cross-sectional study conducted in 10neurologic clinics located in Tehran, Iran, over 2years. The sample size was calculated as 189, including 63migraine and 126non-migraine patients. Asignificant difference was observed in the mean score of the global Pittsburgh Sleep Quality Index (PSQI) between migraine and non-migraine groups (p-value = 0.002), and in the individual components of the PSQI. However, there were no significant differences in the frequency of different types of chronotype (p-value = 0.125, T = 1.541) or OSA risk between the two groups (p-value = 0.568, T = -0.573). The binary logistic regression model showed that the relationship between global PSQI and migraine was significant (p = 0.002). Sleep quality is aproblem for elderly migraine sufferers. Meanwhile, certain factors such as chronotype and OSA have no significant relationship with migraine among community-dwelling seniors. Further studies are required to enhance our understanding of this observation.

Impacts of Remote Physical Exercises on Functional Status and Mobility among Community-Dwelling Pre-Disabled Seniors during the Covid-19 Lockdown.

To assess whether remote physical exercise interventions helped maintain function in daily life, level of physical activities, basic mobility and frailty status in pre-disabled seniors during the first Covid-19 lockdown. This is an interventional study conducted from May 2020 to May 2021. Community-dwelling older adults in 2 Canadian cities. 84 pre-disabled seniors. 12-week physical exercise programs (1 hour/ 3 times/ week) in kinesiologist-guided groups using Zoom or phone-supervised individual booklet-based home-program (n=44) vs. Control (usual life habits; n=40). Functional status in daily activities (OARS scale); Daily level of aerobic (TAPA-1) and strengthening/flexibility (TAPA-2) physical activities; Basic mobility abilities (SPPB: balance, lower limbs strength, walking speed; Timed Up-and-Go) and Frailty (SOF index) were assessed at baseline and at 3, 6, 9 and 12-month follow-ups. The participants' mean age was 78.5 ± 7.2 and 76.5 % were women. There was a group * time effect for the OARS scale (p=0.02), the TAPA-1 (p=0.06) and the TAPA-2 (p=0.007) scores. For these outcomes, scores significantly improved during the first 3 months of follow-up and then stabilised in the intervention group whereas they remained constant in the control group over time. There was an overall time effect for the SPPB (p=0.004), the 4-m walking speed (p=0.02) and for the SOF index (p=0.004), with no between-group differences. Finally, no effect was observed for the TUG. Remote home-based physical exercise interventions and monitoring during the first Covid-19 lockdown seemed to have helped maintain seniors' level of physical activities without impacting on basic mobility abilities. Further studies are needed to identify parameters of remote exercise programs that can improve daily function and mobility in this population.

Smartphones and Threshold-Based Monitoring Methods Effectively Detect Falls Remotely: A Systematic Review.

In the US, at least one fall occurs in at least 28.7% of community-dwelling seniors 65 and older each year. Falls had medical costs of USD 51 billion in 2015 and are projected to reach USD 100 billion by 2030. This review aims to discuss the extent of smartphone (SP) usage in fall detection and prevention across a range of care settings. A computerized search was conducted on six electronic databases to investigate the use of remote sensing technology, wireless technology, and other related MeSH terms for detecting and preventing falls. After applying inclusion and exclusion criteria, 44 studies were included. Most of the studies targeted detecting falls, two focused on detecting and preventing falls, and one only looked at preventing falls. Accelerometers were employed in all the experiments for the detection and/or prevention of falls. The most frequent course of action following a fall event was an alarm to the guardian. Numerous studies investigated in this research used accelerometer data analysis, machine learning, and data from previous falls to devise a boundary and increase detection accuracy. SP was found to have potential as a fall detection system but is not widely implemented. Technology-based applications are being developed to protect at-risk individuals from falls, with the objective of providing more effective and efficient interventions than traditional means. Successful healthcare technology implementation requires cooperation between engineers, clinicians, and administrators.

Serum vitamin D levels and mortality in Mexicans: results from the Mexican Health and Aging Study.

Background: the population in Latin America is aging and elders face several obstacles for good health, including an elevated frequency of vitamin D deficiency. Thus, identification of patients at high risk to develop its negative consequences should be a priority. Objective: the objective of this analysis was to determine if levels of vitamin D lower than 15 ng/ml are associated with high mortality in Mexican elderly population, from the database of the Mexican Health and Aging Study (MHAS). Methods: prospective, population study in Mexico, that included Subjects of 50 years and older who were evaluated for Serum vitamin D levels during the year 2012 (third wave of the study). Serum 25(OH)D levels were categorized into four groups, based on cutoff points used in previous studies on vitamin D and frailty: < 15, 15-< 20, 20-< 30 and ≥ 30 ng/ml. Mortality was evaluated during 2015 (fourth wave of the study). Hazard ratio was calculated (for mortality) through Cox Regression Model, adjusted for covariates. Results: we included 1626 participants, and those with lower levels of vitamin D were older, more often women, required more aid for activities of daily living, reported higher number of chronic diseases, and lower scores on cognition. The relative risk of death was 5.421 (95 % CI 2.465-11.92, p < 0.001) for the participants with vitamin D levels < 15, which after adjusting for covariates, remained statistically significant. Conclusions: levels of vitamin D lower of 15, are associated with an increase in the rate of mortality in community-dwelling senior Mexicans.

Association Between Procrastination in Childhood and the Number of Remaining Teeth in Japanese Older Adults.

BackgroundProcrastination is associated with stress and unhealthy behaviors. The oral condition reflects the long-term history of an individual’s stress exposure and oral health behaviors; however, empirical studies on the association of procrastination in childhood with remaining teeth in older age are limited. We investigated the association of procrastination in childhood with the number of remaining teeth among community-dwelling older Japanese adults.MethodsIn total, 1,616 community-dwelling senior residents of Wakuya City (Miyagi Prefecture, Japan) who were enrolled in the National Health Plan & the Medical Care System for the Elderly completed a self-administered questionnaire on the number of teeth. Procrastination was measured using a single binary question about timing of holiday homework completion in childhood. The number of remaining teeth was assessed via a questionnaire with response options of ≥20, 10–19, 1–9, and 0 teeth. Ordered logistic regression models with potential confounders (sex, age, maternal education, childhood socioeconomic status [SES], childhood maltreatment, conscientiousness trait) and mediators (adulthood SES, smoking history, alcohol use history) were estimated.ResultsForty-six percent of participants reported a higher tendency to procrastinate in childhood. The proportions of participants with ≥20, 10–19, 1–9, and 0 teeth were 39.6%, 22.7%, 24.0%, and 13.7%, respectively. After adjusting for all covariates, a higher tendency to procrastinate in childhood was significantly associated with having fewer remaining teeth (odds ratio 1.28; 95% confidence interval, 1.05–1.57).ConclusionA higher tendency to procrastinate in childhood was associated with having fewer remaining teeth in later life.

Prevalence and risk factors of untreated thyroid dysfunctions in the older Caucasian adults: Results of PolSenior 2 survey.

IntroductionTo determine the prevalence of treated and untreated thyroid dysfunction and to identify factors associated with increased risk of undiagnosed thyroid dysfunction in older adults.MethodsThe population of 5987 community-dwelling Polish Caucasian seniors aged 60 years and above who participated in the PolSenior 2 study (2018–2019). Population-based cross-sectional multidisciplinary study in design. Data from structured questionnaires, geriatric tests, and scales were obtained from all study participants who underwent anthropometric and blood pressure measurements during three home visits. Assessment of thyroid function was based on TSH serum measurements.ResultsThe prevalence of thyroid dysfunction in the Polish population aged 60 years or above was estimated at 15.5% (21.5% in women and 7.2% in men), with 3.2% of undiagnosed individuals among them. The prevalence of hypothyroidism and hyperthyroidism in the studied group was 13.9% (19.4% in women and 6.3% in men) and 1.6% (2.1% in women and 0.9% in men) respectively, untreated hypothyroidism was revealed in 21.9% (in 160 out of 732 subjects) and untreated hyperthyroidism in 34.2% of subjects (in 41 out of 120 participants). In multiple regression analysis independent risk factors for thyroid disorders being untreated were older age (> 75 years), male sex, a low education level (primary or lower), and low utilization of medical services.ConclusionsOne-fifth of Polish Caucasian seniors with hypothyroidism and one-third with hyperthyroidism are untreated. Older, poorly educated and rarely utilizing medical services seniors, especially men, are more frequently untreated for thyroid dysfunction and some of them do not benefit from contemporary achievements in medicine.

Effects of mind–body exercise Baduanjin on cognition in community-dwelling older people with mild cognitive impairment: A randomized controlled trial

ABSTRACT Objective To determine the effect of a 6-month traditional Chinese mind-body Baduanjin exercise intervention on cognitive ability in older people with Mild cognitive impairment (MCI). Methods A total of 135 community-dwelling seniors with MCI were randomized into either the Baduanjin group (BDJ), the brisk walking group (BWK) or the usual physical activity control group (UPA). Cognitive ability was assessed at baseline, 2, 4 and 6 months post-intervention, and 3 months after the intervention ended. Results After 6 months of intervention, the MoCA score of the BDJ group was significantly higher than that of the UPA group (P < 0.05), The Go/No-go correct numbers of the BDJ group and BWK group were significantly higher than those of the UPA group (P < 0.05). There was no statistical difference in other outcomes, or there were only a tiny effect size. Three months after the intervention, there was no significant difference between the primary and secondary outcomes(P > 0.05). Conclusion The 6-month period of Baduanjin training has positive benefits on global cognitive function and attention function in community-dwelling elderly individuals with MCI. The effect seems to have been transient and needs to be confirmed by additional studies.

Smart fall prediction paradigm for community-dwelling seniors through fitness screening protocols and machine learning

This study aimed to predict the fall risk of community-dwelling seniors through fitness screening protocols and machine learning algorithms. Specifically, a customized questionnaire, simple functional performance tests (six items), and physical fitness tests (six items) were employed. A data processing was conducted to enhance the performance, including a deep neural network-based imputation approach (DataWig), an adaptive index filtration algorithm (multi-ReliefF), and decision tree (DT)-based prediction models. Historical data contained 215 community-dwelling seniors were used, and results showed that the proposed paradigm achieved promising and stable performance (e.g., accuracy: 0.933–0.950, F1-score: 0.951–0.955). The developed DT models presented satisfactory performance (top three in almost all evaluation metrics), and the utilized multi-ReliefF enhanced the accuracy (from 1.0% to 3.1%). These results indicated that the proposed paradigm could be a helpful tool for monitoring the health conditions of seniors during their daily exercises, which could help reduce the risk of falls.

Correlation of static and dynamic balance with fear of falls in institutionalised elderly

Background:- Fear of Falling (FoF) is described as a disproportionate fear of falling or the notion that one cannot avoid falling. To remain physically active, you must maintain your balancing function. Fear of falling is one of the leading causes of actual falls among the elderly, according to previous research. In hospitalized aged people, falls and starts falling injuries are more prevalent than in community-dwelling seniors. It is an established fact that with age the person’s ability to maintain balance reduces and along with FoF further restricts mobility and movement. Hence finding correlation among them is important, because no exact correlation has been done between the two. Methodology – The research was carried out in Pune, India. The approach of easy sampling was used to choose 90 samples. Individuals above the age of 60 were chosen based on selected studies. The Falls Efficacy Scale-International was used to quantify fear of falling, while FICSIT-4 and TUG were used to record stationary and non - stationary balance. Results - The data was therefore correlated using Pearson's correlation coefficient after passing the Normality test.

A Neuropsychological Approach to Mild Cognitive Impairment.

A neuropsychological approach to the detection and classification of mild cognitive impairment (MCI) using "gold standard" clinical ratings (CRs) was examined in a sample of independently functioning community dwelling seniors. The relationship between CRs and life satisfaction, concurrent validity of cognitive screening measures, and agreement between CRs and existing criteria for MCI were also determined. One hundred and forty-two participants, aged 75years and older, were administered a comprehensive battery of neuropsychological tests, along with self-report measures of psychological and psychosocial functioning, and functional independence. CRs were based on demographically corrected neuropsychological variables. The prevalence of MCI identified using CRs in this sample was 26.1%. Single and multiple domain subtypes of MCI were readily identified with subtypes reflecting Amnestic and Executive Function impairment predominating. Executive Function was a significant predictor of Life Satisfaction. The MoCA and MMSE both showed weak performance in detecting MCI based on CRs. There was substantial agreement between CRs and the classification criteria for MCI defined by Petersen/Winblad and Jak/Bondi. A global deficit score had near perfect performance as a proxy for CRs in detecting MCI in this sample. The results provide strong support for the utility of neuropsychological CRs as a "gold standard" operational definition in the detection and classification of MCI in older adults.

Gonadotropins at Advanced Age - Perhaps They Are Not So Bad? Correlations Between Gonadotropins and Sarcopenia Indicators in Older Adults.

Many hormones fluctuate during the aging process. It has been suggested that gonadotropins, which increase with age, contribute to the occurrence of many diseases and syndromes in older life, such as cardiovascular diseases, obesity, frailty syndrome and osteoporosis. This study aims to assess the relationship between circulating gonadotropins and other hormones potentially contributing to age-related functional decline and sarcopenia indicators in 39 male and 61 female community-dwelling seniors, mean age 80 years. According to the definition developed by the second European Working Group on Sarcopenia in Older People (EWGSOP2), the following indicators of the sarcopenia were assessed: bioimpedance-measured body composition, gait speed, handgrip strength, timed up and go test (TUG), chair stand test, Short Physical Performance Battery (SPPB). Blood levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, testosterone, dehydroepiandrosterone sulphate (DHEAS) and cortisol were also measured. In the men, FSH and partially LH correlated positively with muscle mass percentage, gait speed, handgrip strength and SPPB, and negatively with percent body fat. Additionally, testosterone and DHEAS correlated negatively with the percentage of fat mass in men. Whereas in the women, FSH and LH were mainly negatively associated with body mass and adipose tissue measures. Cortisol did not show any relationship with the examined indicators. The study shows that the indicators of sarcopenia are strongly associated with levels of gonadotropins, sex hormones and DHEAS, especially in older men. The obtained results, after being confirmed in a larger group, may modify prevention and treatment strategies of sarcopenia.

Community-Academic Partnership to Improve Nutrition and Blood Pressure in Seniors: Outcomes &amp; Impact of COVID-19

The Dietary Approaches to Stop Hypertension (“DASH diet”) has been proven in research settings to lower blood pressure, but its implementation is untested among seniors in congregate meals settings. We report the planning, implementation, impact of COVID-19, and results of an Administration of Community Living-funded study to test whether two evidence-based interventions - DASH-alignment of congregate meals, and home blood pressure self-monitoring, can lower systolic blood pressure and increase blood pressure control among community-dwelling seniors.. Congregate meal menus were aligned with the DASH eating plan, through collaboration of Bionutrition professionals on the research team, CBN food services leadership, and the NYC Department for the Aging. Seniors provided feedback on the DASH-modified meal options. The intervention began on October 15, 2019 (Site 1) and February 3, 2020 (Site 2). The study was interrupted by the COVID-19 pandemic in March 2020, when congregate meals ceased, and when approximately 75% of primary outcome data were collected. Modified implementation permitted completion of modified study outcomes. Preliminary analyses suggest that some participants were able to lower their blood pressure in this program. The DASH diet implemented in the congregate meal setting, along with programs to support BP self-efficacy through modification of existing programs, may be a valuable and scalable model to reduce cardiovascular risk among community-living seniors.

Changing Family Relationships During the COVID-19 Pandemic: The Case of Elder Abuse

Since the first confirmed case being identified in January 2020, authorities in Hong Kong have implemented various measures in an attempt to control the spread of the disease. These measures include compulsory quarantining of infected persons and those suspected of exposure, temporary closure of high-risk premises, and suspension of public activities and services, encouraging work-from-home arrangement etc. These measures, however, may exacerbate the impact of known risk factors and create new avenues for elder mistreatment. Life stress, financial strains and work-from-home arrangements increase chances of family conflicts, cessation of public services increases burden in the already stressed caregivers. This study examines the changing intergenerational family relations in the midst of the pandemic. A total of 1200 community dwelling senior citizens participated through responding to a telephone survey. Information was collected on participants’ demographic characteristics, perceived disruptions brought about by COVID-19, family relations, physical and mental health, etc. Family conflicts and abuse were commonly reported: 27.8% reported family conflicts, 14.5% psychological abuse, 3.1% physical abuse, 3.9% financial abuse. A large proportion of participants (41.8%), however, also reported improved family relations during the pandemic. Results of logistic regression indicate that advanced age, female gender, poor financial situation were significant predictors for family conflicts and abuse. Contrary to our expectations, pandemic related disruptions in daily lives and perceived safety in the community were not associated in family conflicts and abuse in the present sample.

Understanding Global Deprescribing Policy: Opportunities and Challenges

The landscape of deprescribing, the planned process of dose reduction or stoppage for medications which are no longer of benefit, has been rapidly expanding with global efforts and the formation of regional and national deprescribing networks. The purpose of this qualitative study is to describe successes and challenges about deprescribing from thought-leaders across the world to inform future policy initiatives. We aim to conduct at least 15 key informant (KI) interviews; we have completed 13 to date. Codes were constructed to identify themes that depict the perspectives regarding deprescribing policy across the globe. The KIs primarily represent the fields of pharmacy and medicine from four global regions with years of deprescribing experience ranging from 5 to > 20. We identified two emerging overarching themes through our qualitative analysis: Regional Organization Support and Evidence & Knowledge gaps. Within these overarching themes, we further identified sub-themes and their representative quotes: Network Structure: “idea of the network was threefold: 1) To try and figure out what we need to activate healthcare providers to deprescribe; 2) To do work with community-dwelling seniors to motivate them and give them opportunities to deprescribe; 3) ...getting pharmacists to provide the education to the patients.” Cost-effectiveness: “If we can show that it is cost-effective to deprescribe, that there is actually a return here, not just in health terms but in monetary terms, I think that would really push it along.” This research will help to advance global efforts to optimize medication management.

Diabetes is a risk factor for hearing loss in older adults: Results of a community screening programme.

To investigate the association between diabetes mellitus (DM) and the prevalence and severity of hearing loss in a population of community-dwelling older adults in Singapore. This is a retrospective, cross-sectional study of 1787 adults aged 60-100 who had undergone a comprehensive audiological assessment in a community-based audiology clinic. Data extracted included their age, hearing profile, medical history, and comorbidities collected through verbal interview at the point of audiologic assessment. Multivariate linear regression and multivariate logistic regression were performed to investigate the relationship between DM and hearing loss. The prevalence of DM in our studied population is 17.9%. After controlling for age, gender, race, hypertension, and hyperlipidaemia status, DM was found to be independently associated with at least moderate hearing loss (adjusted OR 1.3 [95% CI 1.06-1.59], p=.012). This was especially so in the younger (<70) age group (adjusted OR 1.7 [95% CI 1.18-2.44], p=.004). DM is an independent risk factor for the presence of at least moderate hearing in community-dwelling seniors. Individuals aged <70 with DM should be screened for hearing loss to enable early intervention.

Acceptability and feasibility of public square dancing for community senior citizens with mild cognitive impairment and depressive symptoms: A pilot study

ObjectivesTo explore the acceptability and feasibility of public square dancing among community residents with mild cognitive impairment (MCI) and depressive symptoms. MethodsThis mixed-method study consisted of a quantitative and a qualitative phase. From January to July 2018, a total of 241 community-dwelling senior citizens who complained of memory loss in one community in the Haidian District in Beijing were approached and screened, and 41 qualified for the study. Among them, 35 senior citizens participated in the public square dancing intervention. By the end of the three-month follow-up, 31 senior citizens completed the whole study. The Subjective Exercise Experience Scale (SEES) was used to survey senior citizens at the end of the three-month public square dancing intervention and follow-up to measure the participants’ subjective exercise experience. Then 15 senior citizens were interviewed to collect attitudes, opinions, and suggestions related to the intervention. ResultsDuring the intervention, 90.6% of senior citizens met the requirement for defined hours. All senior citizens continued to dance at the three-month follow-up, and 32.3% met the requirement for defined hours. The scores of psychological well-being (11.03 ± 2.82 vs. 14.87 ± 3.93, P < 0.001) and fatigue (11.00 [8.00, 12.00] vs. 14.00 [9.00, 18.00], P < 0.001) increased at the end of the three-month follow-up. Qualitative research results extracted four major themes: increased confidence and a sense of accomplishment; easy to learn, close to real life, and sense of belonging; promotes physical and mental health; future expectations include music selection, reduced weather disruption, and self-organizing workouts. ConclusionPublic square dancing proved to be an acceptable, viable, and valuable intervention for MCI residents with depressive symptoms, which could be carried out by nursing staff in the community. Future studies should consider the appropriate population, intensity, and frequency of public square dancing and its effect on specific cognitive functions.

A Modified CAIDE Risk Score as a Screening Tool for Cognitive Impairment in Older Adults.

Although an efficacious dementia-risk score system, Cardiovascular Risk Factors, Aging, and Dementia (CAIDE) was derived using midlife risk factors in a population with low educational attainment that does not reflect today's US population, and requires laboratory biomarkers, which are not always available. Develop and validate a modified CAIDE (mCAIDE) system and test its ability to predict presence, severity, and etiology of cognitive impairment in older adults. Population consisted of 449 participants in dementia research (N = 230; community sample; 67.9±10.0 years old, 29.6%male, 13.7±4.1 years education) or receiving dementia clinical services (N = 219; clinical sample; 74.3±9.8 years old, 50.2%male, 15.5±2.6 years education). The mCAIDE, which includes self-reported and performance-based rather than blood-derived measures, was developed in the community sample and tested in the independent clinical sample. Validity against Framingham, Hachinski, and CAIDE risk scores was assessed. Higher mCAIDE quartiles were associated with lower performance on global and domain-specific cognitive tests. Each one-point increase in mCAIDE increased the odds of mild cognitive impairment (MCI) by up to 65%, those of AD by 69%, and those for non-AD dementia by > 85%, with highest scores in cases with vascular etiologies. Being in the highest mCAIDE risk group improved ability to discriminate dementia from MCI and controls and MCI from controls, with a cut-off of ≥7 points offering the highest sensitivity, specificity, and positive and negative predictive values. mCAIDE is a robust indicator of cognitive impairment in community-dwelling seniors, which can discriminate well between dementia severity including MCI versus controls. The mCAIDE may be a valuable tool for case ascertainment in research studies, helping flag primary care patients for cognitive testing, and identify those in need of lifestyle interventions for symptomatic control.

Matching Digital Intervention Affordances with Tasks: The Case of a Zoom and WhatsApp Mental Health Intervention for Seniors during the COVID-19 Pandemic

ABSTRACT During the first COVID-19 wave, we conducted a Zoom and WhatsApp digital group intervention that promoted community-dwelling seniors’ mental health. A total of 82 community-dwelling adults participated in this intervention. Based on the media richness theory (MRT) and the affordances approach, we used netnography to explore how group moderators and technical support team members (n = 9), but not the seniors themselves, perceived the ways Zoom and WhatsApp technological affordances/constraints matched intervention tasks and increased intervention performance. We identified four Zoom and WhatsApp affordances: temporality, interactivity, multimediality, and portability. Empirically, our findings represent a first step in creating a conceptual framework for analyzing digital intervention performances that addresses users’ perceptions of technologies and intervention goals. Theoretically, our synergic analysis of MRT and the affordances approach offers a cohesive framework that shifts from a focus on users’ interactions with one type of media to their interactions with all media that are used in attaining intervention goals.

Epidemiology of dementia onset captured in Canadian primary care electronic medical records.

Dementia is an increasing concern in many countries, especially in those experiencing rapid growth in the proportion of older adults in their population. This study aims to describe trends and demographic characteristics of incident dementia cases in community-dwelling older adults managed by primary care physicians. We used electronic medical records from the Canadian Primary Care Sentinel Surveillance Network database to conduct a retrospective analysis to determine the number of, and trends for, incident diagnoses of dementia. Age-standardized annual incidence rates were calculated. Participants in our cohort are Canadian community dwelling seniors aged 65+ years who were not diagnosed with dementia before baseline with at least six years of record at their primary care clinics. The cohort consisted of 39 067 patients of whom 57% were females; the mean (SD) follow-up was 8.4 (1.5) years. During follow-up, 4935 patients were diagnosed with dementia. The risk for dementia diagnosis increased with increasing age but decreased in the last four years among people aged 80 and older at baseline (P < 0.001). People with dementia were more likely to be females (P = 0.001) and urban residents (P < 0.001), they are less likely to be classified into the least deprived group (P = 0.012). The incidence of dementia diagnosis increased with age except in the oldest old in both sexes. This may be attributed to the effect of mortality competing risk. Future research on the association between risk factors and dementia should consider studying dementia among the oldest old separately to minimize bias.
