Oral health and self-rated health in community-dwelling older adults in Colombia

BACKGROUND

The relationship between oral health and specific health conditions, such as cardiovascular disease or cognitive impairment, has been extensively studied. However, the effect of oral health status on self-rated health has not been assessed. This could be relevant in older people considering that poor self-rated health status and oral diseases are highly prevalent in this population. The aim of this study was to determine the association between different parameters of oral health and self-rated health status (SRHS) in Colombian community-dwelling older adults.

METHODS

This is a secondary analysis of the SABE-Colombia study performed in 2015. The dependent variable was defined as the SRHS status assessed by the question "Compared with other people, your age: Do you consider your health status to be better, equal, or worse?" We considered four independent variables: total edentulism considering the high prevalence in older people, the GOHAI score to assess self-rated oral health, and the use of fixed and removable dental prostheses as potential modifiers of oral health. An adjusted ordinal logistic regression was performed by each independent variable.

RESULTS

After the exclusion of missing data, 17,945 persons were included in the final analysis. A total of 10.6% reported worse SRHS, 37.6% reported equal SRHS, and 51.6% reported better SRHS. The worse SRHS group was older and had a higher proportion of dependence, cognitive impairment, and depressive symptoms. The frequency of total edentulism and the lower mean score of GOHAI were significant in the worse SHRS group. An ordinal logistic regression for each independent variable was performed, finding that edentulism increases the probability of worse SHRS, while the GOHAI and use of removable or fixed dental prostheses increase the probability of better SRHS.

CONCLUSION

We found an association between total edentulism, GOHAI Index, the use of dental prostheses (both removable and fixed), and self-rated health status, showing the relevance of oral health status to self-rated health status independent of comorbidities and geriatric syndromes. This result supports the inclusion of oral health evaluation in comprehensive geriatric assessment.

[Translated article] One-year mortality and associated factors in patients undergoing surgery for hip fracture

INTRODUCTION

Hip fractures are very common injuries in elderly patients and are associated with increased mortality.

OBJECTIVE

To identify the factors associated with mortality in patients after one year of being operated for hip fracture in an Orthogeriatric Program.

METHODS

We design an observational analytical study in subjects older than 65 years admitted to the Hospital Universitario San Ignacio for hip fracture who were treated in the Orthogeriatrics Program. Telephone follow-up was performed one year after admission. Data were analyzed using a univariate logistic regression model and a multivariate logistic regression model was applied to control the effect of the other variables.

RESULTS

Mortality was 17.82%, functional impairment was 50.91%, and institutionalization was 13.9%. The factors associated with mortality were moderate dependence (OR=3.56, 95% CI=1.17-10.84, p=0.025), malnutrition (OR=3.42, 95% CI=1.06-11.04, p=0.039), in-hospital complications (OR=2.80, 95% CI=1.11-7.04, p=0.028), and older age (OR=1.09, 95% CI=1.03-1.15, p=0.002). The factor associated with functional impairment was a greater dependence at admission (OR=2.05, 95% CI=1.02-4.10, p=0.041), and with institutionalization was a lower Barthel index score at admission (OR=0.96, 95% CI=0.94-0.98, p=0.001).

CONCLUSIONS

Our results shows that the factors associated with mortality one year after hip fracture surgery were: moderate dependence, malnutrition, in-hospital complications and advanced age. Having previous functional dependence is directly related to greater functional loss and institutionalization.

Self-reported glaucoma prevalence and related factors, contribution to reported visual impairment, and functional burden in a cross-sectional study in Colombia

PURPOSE

Describe the self-reported prevalence of glaucoma in Colombian older adults, emphasizing the most important risk factors and associated daily-life functional alterations.

METHODS

This a secondary analysis of the Health, Wellness, and Aging survey conducted in the year 2015. Diagnosis of glaucoma was obtained from self-report. Functional variables were assessed through activities of daily living questionnaires. A descriptive analysis followed by bivariate and multivariate regression models adjusting for confounding variables was conducted.

RESULTS

Self-reported prevalence of glaucoma was 5.67%, with higher rate in women, OR 1.22 (1.13-1.40) p = .003, older age OR 1.02 (1.01-1.02) p < .001, and with higher education OR 1.38 (1.28-1.50) p < .001. Glaucoma was independently associated with diabetes OR 1.37 (1.18-1.61) p  < .001 and hypertension 1.26 (1.08-1.46) p = .003. It also showed statistically significant correlations with poor SRH OR 1.15 (1.02-1.32) p < .001, self-reported visual impairment 1.73 (1.50-2.01) p < .001, and impairment in money management OR 1.59 (1.16-2.08) p  = .002, grocery shopping OR 1.57 (1.26-1.96) p < .001 and preparing meals OR 1.31 (1.06-1.63) p  = .013 and having had falls during the last year OR 1.14 (1.01-1.31) p = 0.041.

CONCLUSION

Our findings suggest the self-reported prevalence of glaucoma in older adults in Colombia to be higher than reported data. Glaucoma and visual impairment in older adults represent a public health concern, since glaucoma was associated with adverse outcomes like functional loss and risk of falling, affecting the quality of life and their participation in society.

Our results shows that the factors associated with mortality one year after hip fracture surgery were: moderate dependence, malnutrition, in-hospital complications and advanced age. Having previous functional dependence is directly related to greater functional loss and institutionalization.

Effect of multicomponent exercise in cognitive impairment: a systematic review and meta-analysis

Background

Multicomponent physical exercise is the most recommended type of physical intervention in older adults. Experimental data suggest the relevance of the muscle-brain axis and the relationship between muscle contraction and release of brain-derived neurotrophic factor, however, the impact of this relationship on cognition remains unclear, especially in people with diagnosis of cognitive impairment. This study assesses the effect of multicomponent physical exercise on global cognition in people with mild cognitive impairment or dementia.

Methods

Randomized controlled trials published until January 2021 were searched across three electronic databases (PubMed, Scopus, and Cochrane Database). Data about exercises included in the multicomponent intervention (endurance, strength, balance, or flexibility), the inclusion of aerobic exercise, and the change in global cognition were extracted. The effect size was represented as a standardized mean difference. Risk of bias was assessed by the RoB2 tool.

Results

A total of 8 studies were included. The overall effect size suggested an effect of multicomponent exercise on global cognition. However, the subgroup analysis showed an effect only when aerobic exercise was included in the intervention. No effect when mild cognitive impairment and dementia were assessed separately was found.

Conclusion

This study suggests that multicomponent physical exercise could have an effect on global cognition in people with mild cognitive impairment or dementia only when aerobic exercise is included in the intervention. Our results support the inclusion of structured physical exercise programs in the management of people with cognitive impairment.

Motoric Cognitive Risk Syndrome: Prevalence and Cognitive Performance. A cross-sectional study

BACKGROUND

Motoric Cognitive Risk Syndrome (MCR) is a predementia stage where slow gait speed and subjective memory complaints are present. The purpose of this study was to estimate the prevalence of MCR and assess its relationship with sociodemographic factors and chronic conditions.

METHODS

This is a secondary analysis of the SABE Colombia study conducted in 2015. The analytic sample consisted of 17·577 participants. After determining MCR prevalence, logistic regression was performed to examine the correlates of MCR.

FINDINGS

The prevalence of MCR was 10·71 %. The median age was 71 years and women composed 74·63 % of the MCR group. After adjusting for confounding variables MCR was associated with increasing age (OR 1·69, CI 1·43 - 1·92), no or low education (OR 1·99, CI 1·67- 2·37), MMSE (OR 0·93, CI 0·91 - 0·95) and chronic conditions such as mental disorders (OR 1·36, CI 1·11-1·67), history of myocardial infarction (OR 1·24, CI 1·04 - 1·47), hypertension (OR 1·23, CI 1·08 - 1·40) and diabetes (OR 1.18, CI 1.01 - 1.37).

INTERPRETATION

This study found a prevalence of 10·71 % of MCR in Colombian older adults. Additionally, MCR was associated with chronic conditions and sociodemographic factors identified in prior studies. These results increase the awareness of a novel predementia stage whose identification can be performed by clinicians in the outpatient clinic, minimizing the cost of a full neuropsychologic evaluation performed in a memory clinic.

Motoric cognitive risk syndrome: Prevalence and cognitive performance

INTRODUCTION

Cognitive decline and dementia have a significant impact on the quality of life of older adults and their caregivers. Increasing and optimizing accessibility of clinical dementia risk assessment is important to set up preventive measures and reduce health care costs. Motoric Cognitive Risk Syndrome (MCRS) is a pre-dementia stage where slow gait speed and subjective memory complaints are present, but where cognitive performance is adequate and without functional impairment. In addition to dementia, MCRS seems to increase the risk of having other geriatric outcomes including frailty, disability, falls and overall mortality.

METHODS

Data from the SABE Colombia study (Health, Well-Being, and Aging) conducted in 2015 in community-dwelling adults aged 60 years and older. Using the 4 aspects considered within the MCRS definition, we evaluated the presence of this syndrome and factors associated in this population with regression models. A sub-sample of 19,004 participants was obtained.

RESULTS

The multivariate analysis showed a prevalence of 5,45% of MCRS. After adjusting for cofounding variables MCRS was associated with MMSE (OR 0.90, CI 0.82-0.99; p 0.028) and frailty (OR 9.1, CI 3.26-25.47, p 0.000; OR 21.38, CI 6.30-72.57, p 0.000).

CONCLUSION

This study found a prevalence of 5.45% of MCRS in Colombian older adults. We found an association between cognitive performance (MMSE), frailty and MCRS. Our results increase the awareness of a pre-dementia stages different to Mild Cognitive Impairment (MCI), as these individuals are at greater risk than those with MCI to develop dementia.

Effect of physical activity on cognitive domains in dementia and mild cognitive impairment: overview of systematic reviews and meta-analyses

OBJECTIVE

To assess the effect of physical activity on cognitive domains in persons with dementia or mild cognitive impairment.

DESIGN

An overview of systematic reviews and meta-analyses of randomized controlled trials were performed.

METHODS

A literature search was performed in PubMed, Scopus, and Cochrane Database of Systematic Reviews databases up to February 2020. Data about the change in cognitive domains after physical activity intervention was extracted and plotted.

RESULTS

We included 11 meta-analyses in this overview. The most frequent type of physical activity for the intervention group was the aerobic exercise with a duration between 6 and 78 weeks. Global cognition was the most common form of assessing the cognitive function, follow of executive function, delayed recall, attention, and verbal fluency. We found a positive effect of physical activity on global cognition, executive function, and delayed recall, but no effect on verbal fluency, attention, and immediate recall.

CONCLUSION

Physical activity shows a positive effect on cognition in people with dementia and mild cognitive impairment, especially when it was assessed as global cognition. Positive effects on executive function and memory were also shown. This result confirms the relevance of physical activity in the treatment of persons with cognitive impairment.

Association of Malnutrition with Functional and Cognitive Trajectories in People Living with Dementia: A Five-Year Follow-Up Study

BACKGROUND

In dementia, functional status depends on multiple factors in addition to cognition. Nutritional status is a potentially modifiable factor related to homeostasis and proper functioning of body systems and may contribute to cognitive and functional decline.

OBJECTIVE

This paper aims to analyze the association of malnutrition with the course of cognitive and functional decline in people living with dementia.

METHODS

This is an analysis of a longitudinal cohort study, the Dementia Study of Western Norway. Data of 202 patients diagnosed with mild dementia were analyzed; Alzheimer's disease (AD) (n = 103), Lewy body dementia (LBD) (n = 74), and other dementias (OD) (n = 25). Cognition was assessed with the Mini-Mental State Examination and functional decline through the activities of daily living included in the Rapid Disability Rating Scale. The Global Leadership Initiative on Malnutrition Index was used to determine nutritional status. Associations of nutritional status with cognitive and functional decline were evaluated through adjusted linear mixed models.

RESULTS

At baseline, the prevalence of general malnutrition was 28.7%; 17.3% were classified as moderate malnutrition and 11.38% as severe malnutrition (there were no significant differences between AD and LBD). Malnutrition at diagnosis and over follow-up was a significant predictor of functional-decline, but not of cognitive decline.

CONCLUSION

According to our results malnutrition was associated with faster functional loss but, not cognitive decline in older adults with dementia. A more comprehensive dementia approach including nutritional assessments could improve prognosis.

Benzodiazepines and antidepressants: Effects on cognitive and functional decline in Alzheimer's disease and Lewy body dementia

OBJECTIVES

We aim to study the effects of the prescription of benzodiazepines and antidepressants on cognitive and functional decline in older adults living with Alzheimer's disease (AD) and Lewy body dementia (LBD) over a 5-year follow-up.

METHODS

This is a longitudinal analysis of a Norwegian cohort study entitled "The Dementia Study of Western Norway" (DemVest). We included 196 patients newly diagnosed with AD (n = 111) and LBD (n = 85), followed annually for 5 years. Three prescription groups were defined: only benzodiazepines (BZD), only antidepressants (ADep), and the combination of benzodiazepines and antidepressants (BZD-ADep). Linear mixed-effects models were conducted to analyze the effect of the defined groups on the outcomes. The outcomes were functional decline, measured by the Rapid Disability Rating Scale-2, and cognition measured with the Mini-Mental State Examination.

RESULTS

Prescription of the combination of benzodiazepines and antidepressants in LBD was associated with faster functional decline. In AD, the prescription of BZD and BZD-ADep was associated with greater functional deterioration. ADep alone did not show positive or negative significant associations with the studied outcomes.

CONCLUSIONS

BZD and especially the combination of BZD and ADep are associated with functional decline in AD and LBD and should be used cautiously.

Body mass index, performance on activities of daily living and cognition: analysis in two different populations

BACKGROUND

With this study, we aim to determine the associations of the different categories of the body mass index (BMI) with activities of daily living (ADL) and cognitive performance in two different populations living in the community; Colombian and South Korean older adults.

METHODS

We performed a cross-sectional analysis of two surveys separately; The Survey on Health, Well-Being, and Aging in Colombia (SABE) (n = 23,343) and the Korean Longitudinal Study of aging (KLoSA) (n = 4556). Participants older than 50 years were selected from rural and urban areas achieving a representative sample. Here we investigated the association between BMI categories with function using zero-inflated negative binomial regressions, and with cognition using logistic regression models.

RESULTS

After adjustment, in Colombia, underweight was associated with an impaired score on the Mini-mental State Examination (MMSE) and worse performance in the instrumental activities of daily living (IADL). Also, being overweight was associated with a better score on the MMSE and the IADL. For both outcomes education level significantly influenced the predictions. In South Korea, there were no significant associations for cognition, IADL, or basic activities of daily living (BADL).

CONCLUSIONS

In the Colombian population, underweight, was associated with reduced cognitive performance and daily functioning. Additionally, being overweight but not obese was associated with better cognition and daily functioning. In South Korea, there were no significant associations between BMI and cognition, IADL, or BADL.

Performance of the Short Physical Performance Battery in Identifying the Frailty Phenotype and Predicting Geriatric Syndromes in Community-Dwelling Elderly

The early identification of seniors at high risk of geriatric syndromes is fundamental for targeting interventions to those who most need them. To date, the predictive value of the Short Physical Performance Battery (SPPB) for multifactorial clinical conditions has not been clearly established. Thus, the aim of the present study was to determine whether the SPPB could identify frailty and predict geriatric syndromes in community-dwelling older adults. Participants comprised men and women aged 60 years and older who participated in the Health and Well-being and Aging Survey in Colombia 2015 (n=4125, 57.6% women). A structured interview was administered to obtain socio-demographic data which included age, sex, ethnicity, socioeconomic status, and urbanicity. The study included the measurement of body mass, grip strength, SPPB, Lawton´s instrumental ADL scale, specific subjective memory complaints (SSMC), frailty phenotype (Fried and FRAIL Scale), and self-reported falls, geriatric syndromes and/or medical conditions. ROC analysis was used to examine the ability of the SPPB test to predict frailty and geriatric syndromes. The cutoff that maximized both sensitivity and specificity for the frailty phenotype was 8 points or below for men and 7 points or below for women. These cutoff values significantly predicted four geriatric syndromes in descending order: mild dementia (♂ ORajus 3.34, and ♀ ORajus 2.79), low grip strength (♂ ORajus 1.98, and ♀ ORajus 2.45), falls (♂ ORajus 1.39, and ♀ ORajus 1.49), and SSMC (♂ ORajus 1.39). In summary, the main finding of the present study was that SPPB score (i.e., ≤ 8 ♂ and ≤ 7 ♀) seems to be a useful measure for identifying the physical frailty phenotype and predicting geriatric syndromes in community-dwelling older adults.

The Influence of Lifestyle Behaviors on the Incidence of Frailty

BACKGROUND

Frailty is a clinical state defined as an increase in an individual's vulnerability to developing adverse health-related outcomes.

OBJECTIVES

We propose that healthy behaviors could lower the incidence of frailty. The aim is to describe the association between healthy behaviors (physical activity, vaccination, tobacco use, and cancer screening) and the incidence of frailty.

DESIGN

This is a secondary longitudinal analysis of the Mexican Health and Aging Study (MHAS) cohort.

SETTING

MHAS is a population-based cohort, of community-dwelling Mexican older adults. With five assessments currently available, for purposes of this work, 2012 and 2015 waves were used.

PARTICIPANTS

A total of 6,087 individuals 50-year or older were included.

MEASUREMENTS

Frailty was defined using a 39-item frailty index. Healthy behaviors were assessed with questions available in MHAS. Individuals without frailty in 2012 were followed-up three years in order to determine their frailty incidence, and its association with healthy behaviors. Multivariate logistic regression models were used to assess the odds of frailty occurring according to the four health-related behaviors mentioned above.

RESULTS

At baseline (2012), 55.2% of the subjects were male, the mean age was 62.2 (SD ± 8.5) years old. The overall incidence (2015) of frailty was 37.8%. Older adults physically active had a lower incidence of frailty (48.9% vs. 42.2%, p< 0.0001). Of the activities assessed in the adjusted multivariate models, physical activity was the only variable that was independently associated with a lower risk of frailty (odds ratio: 0.79, 95% confidence interval 0.71-0.88, p< 0.001).

CONCLUSIONS

Physically active older adults had a lower 3-year incidence of frailty even after adjusting for confounding variables. Increasing physical activity could therefore represent a strategy for reducing the incidence of frailty. Other so-called healthy behaviors were not associated with incident frailty, however there is still uncertainty on the interpretation of those results.

ASSOCIATION OF DEPRESSIVE SYMPTOMS AND SUBJECTIVE MEMORY COMPLAINTS WITH THE INCIDENCE OF COGNITIVE IMPAIRMENT IN OLDER ADULTS WITH HIGH BLOOD PRESSURE

PURPOSE

High blood pressure is a relevant risk factor for vascular damage, leading to development of depressive symptoms and dementia in older adults. Moreover, subjective memory complaints are recognized as an early marker of cognitive impairment. However, it has been established that subjective memory complaints could also be a reflection of depressive symptoms. The objective of this paper is to assess the impact of depressive symptoms and subjective memory complaints on the incidence of cognitive impairment in older adults with high blood pressure.

METHODS

This is a secondary analysis of the Mexican Health and Aging Study, a representative cohort composed by individuals aged ≥ 50 years. Participants with cognitive impairment in 2012 were excluded since the outcome was incident cognitive impairment in 2015. Four groups were created according to depressive symptomatology and subjective memory complaints status, analyses were stratified according to blood pressure status. The odds incident cognitive impairment was estimated through logistic regression models.

RESULTS

A total of 6,327 participants were included, from which 6.44% developed cognitive impairment. No differences were seen regarding the development of cognitive impairment in participants without high blood pressure. However, increased risk was evident in those with both high blood pressure and depressive symptoms (OR=2.1, 95% CI 1.09 - 4.09, p =0.026) as with high blood pressure, depressive symptoms and subjective memory complaints (OR=1.91, 9% CI 1.4 - 3.2, p= 0.001).

CONCLUSION

Individuals with high blood pressure have a higher risk of developing incident cognitive impairment when depressive symptoms and/or subjective memory complaints are present. Our results suggest that a sequence of events related to altered cerebral vascular dynamics is possible.

[Multimorbidity, Depressive Symptoms, and Self-Reported Health in Older Adults: a Secondary Analysis of the Sabe Bogota Study]

Background

Multimorbidity and depressive symptoms (DSs) are common in older adults. Self-rated health (SRH) allows detection of elderly adults with a high burden of multimorbidity plus depression. The aim of this study was to test the association of groups of multimorbidity and DS on SRH in Colombian older adults.

Methods

We conducted a cross-sectional study in 2012 in Bogotá, Colombia, called "Salud, Bienestar y Envejecimiento" (Health, Well-being, and Aging), including 2000 community-dwelling adults 60 years of age or older. SRH was assessed with the question "How would you rate your health?" giving five possible answers. DSs were rated using the 15-question version of the geriatric depression scale, and multimorbidity was defined as having two or more chronic diseases. A logistic regression model was used to identify the association between grouped DS and multimorbidity with SRH.

Results

Groups were distributed as follows: 678 with no DS/no multimorbidity (33.9%), 808 with only multimorbidity (40%), 128 with DS only (6.4%), and 386 with DS/multimorbidity (19.3%). An association of fair/poor SRH with DS/multimorbidity group was found (odds ratio 5.5; 95% confidence interval 3.86-7.95, p < 0.001) when compared to subjects without any of those conditions.

Conclusion

There was an incremental association between DS and multimorbidity with SRH. An older adult referring to his or her own health with a negative connotation should alert to a higher burden of diseases, including DS.
