Falls among community-dwelling older adults in the Philippines and Viet Nam: Results from nationally representative samples

Falls are a significant public health issue globally. However, studies with nationally representative samples have yet to be done to understand falls among older adults in the Philippines and Viet Nam. Using a biopsychosocial perspective, this study investigated the prevalence of falls and their associated factors among community-dwelling older adults in these countries. Cross-sectional data were drawn from the baseline survey of the Longitudinal Study of Ageing and Health in the Philippines (2018, N = 4,606) and the Longitudinal Study of Ageing and Health in Viet Nam (2018, N = 4,378). The outcome variables were any falls in the past year. Independent variables included sociodemographic factors (age, sex, education, living in urban areas, living alone, social network size), biophysical factors (vision, chronic conditions, functional impairments, pain locations, insomnia symptoms, sleep medications, grip strength, walking speed, postural control), and psychological factors (depressive symptoms). Descriptive analysis and logistic regression analysis were used to analyze the data. The results showed that 17.7 % and 7.3 % of older Filipino and Vietnamese adults fell in the year before the study. Significant factors associated with the odds of any falls among Filipino older adults were having a higher level of education, living in urban areas, living with others, experiencing more functional impairments, reporting one or more pain locations, and having poor grip strength. In Viet Nam, having more chronic conditions, experiencing more functional impairments, and reporting two or more pain locations were found to be associated with higher odds of any falls. The population in the Philippines and Viet Nam is aging rapidly. Findings from this study are timely in identifying at-risk individuals and preparing for effective fall prevention strategies.

Nutritional Status Predicts Injurious Falls Among Community-Dwelling Older Adults: Does Sex Matter?

The association of poor nutritional status with falls-related injuries other than fractures is unclear. Although there are sex differences in poor nutritional status and the rate of falls-related injuries, whether the impacts of poor nutritional status on falls-related injuries differ by sex is unclear. We investigated whether baseline poor nutritional status predicted injurious falls, fall-related minor injuries, and fractures at 3-year follow-up and whether these relationships differed by sex among community-dwelling older adults (N = 3257). We found that being at risk of malnutrition at baseline significantly predicted injurious falls but not minor injuries and fractures at follow-up. Compared to older males at risk of malnutrition at baseline, females at risk of malnutrition were significantly more likely to have injurious falls and minor injuries later. Being at risk of malnutrition predicted injurious falls, especially among older females. Regular nutritional screenings among older females should be implemented to provide prompt interventions against falls.

Nutrition Strategies Promoting Healthy Aging: From Improvement of Cardiovascular and Brain Health to Prevention of Age-Associated Diseases

BACKGROUND

An increasing number of studies suggest that diet plays an important role in regulating aging processes and modulates the development of the most important age-related diseases.

OBJECTIVE

The aim of this review is to provide an overview of the relationship between nutrition and critical age-associated diseases.

METHODS

A literature review was conducted to survey recent pre-clinical and clinical findings related to the role of nutritional factors in modulation of fundamental cellular and molecular mechanisms of aging and their role in prevention of the genesis of the diseases of aging.

RESULTS

Studies show that the development of cardiovascular and cerebrovascular diseases, neurodegenerative diseases, cognitive impairment and dementia can be slowed down or prevented by certain diets with anti-aging action. The protective effects of diets, at least in part, may be mediated by their beneficial macro- (protein, fat, carbohydrate) and micronutrient (vitamins, minerals) composition.

CONCLUSIONS

Certain diets, such as the Mediterranean diet, may play a significant role in healthy aging by preventing the onset of certain diseases and by improving the aging process itself. This latter can be strengthened by incorporating fasting elements into the diet. As dietary recommendations change with age, this should be taken into consideration as well, when developing a diet tailored to the needs of elderly individuals. Future and ongoing clinical studies on complex anti-aging dietary interventions translating the results of preclinical investigations are expected to lead to novel nutritional guidelines for older adults in the near future.

Sex Differences in Subsequent Falls and Falls Risk: A Prospective Cohort Study in Older Adults

BACKGROUND

Sex differences for subsequent falls and falls risk factors in community-dwelling older adults who have fallen are unknown. Our aim was to: (1) compare the number of falls between sexes, (2) identify modifiable falls risk factors, and (3) explore the interaction of sex on falls risk factors in older adults who fall.

METHODS

Four hundred sixty-two community dwellers seeking medical attention after an index fall were recruited from the Vancouver Falls Prevention Clinic and participated in this 12-month prospective cohort study. Ninety-six participants were part of a randomized controlled trial of exercise. Falls were tracked with monthly falls calendars. Demographics, falls risk measures, and the number of subsequent falls were compared between sexes. A principal component analysis (PCA) was employed to reduce the falls risk measures to a smaller set of factors. The PCA factors were used in negative binomial regression models to predict the number of subsequent falls. Age, exposure time (i.e., number of falls monitoring days), and prescribed exercise (yes/no) were used as covariates, and sex (male/female) and PCA factors were used as main effects. The interaction of sex by PCA factor was then included.

RESULTS

Males fell more over 12 months (males: 2.80 ± 6.86 falls; females: 1.25 ± 2.63 falls) than females, and poorer executive function predicted falls in males. Four PCA factors were defined - impaired cognition and mobility, low mood and self-efficacy, mobility resilience, and perceived poor health - each predicted the number of falls. The sex by mobility resilience interaction suggested that mobility resilience was less protective of falls in males.

CONCLUSION

Modifiable risk factors related to cognition, physical function, psychological wellbeing, and health status predicted subsequent falls. In males, better mobility was not as protective of falls compared with females. This may be due to males' poorer executive function, contributing to decreased judgement or slowed decision-making during mobility. These results may inform efficacious sex-specific falls prevention strategies.

When Will My Patient Fall? Sensor-Based In-Home Walking Speed Identifies Future Falls in Older Adults

BACKGROUND

Although there are known clinical measures that may be associated with risk of future falls in older adults, we are still unable to predict when the fall will happen. Our objective was to determine whether unobtrusive in-home assessment of walking speed can detect a future fall.

METHOD

In both ISAAC and ORCATECH Living Laboratory studies, a sensor-based monitoring system has been deployed in the homes of older adults. Longitudinal mixed-effects regression models were used to explore trajectories of sensor-based walking speed metrics in those destined to fall versus controls over time. Falls were captured during a 3-year period.

RESULTS

We observed no major differences between those destined to fall (n = 55) and controls (n = 70) at baseline in clinical functional tests. There was a longitudinal decline in median daily walking speed over the 3 months before a fall in those destined to fall when compared with controls, p < .01 (ie, mean walking speed declined 0.1 cm s-1 per week). We also found prefall differences in sensor-based walking speed metrics in individuals who experienced a fall: walking speed variability was lower the month and the week just before the fall compared with 3 months before the fall, both p < .01.

CONCLUSIONS

While basic clinical tests were not able to differentiate who will prospectively fall, we found that significant variations in walking speed metrics before a fall were measurable. These results provide evidence of a potential sensor-based risk biomarker of prospective falls in community living older adults.

Longitudinal effects of nocturnal insomnia symptom subtypes and nonrestorative sleep on the incidence of depression among community-dwelling older adults: results from the Health and Retirement Study

OBJECTIVE

The relationships between different insomnia symptom subtypes and the onset of depression among older adults are inconsistent. It may be that each subtype has a distinct temporal effect on depression not easily captured by the different follow-up intervals used in past studies. We systemically investigated the temporal effects by examining the links between subtypes and the onset of depression at different follow-up intervals among community-dwelling older adults.

METHODS

We used the 2006 wave of the Health and Retirement Study as baseline (n = 9151). The outcome was the onset of depression at 2-year (2008 wave), 4-year (2010 wave), and 6-year (2012 wave) follow-ups. The independent variables were difficulty with falling asleep (initial insomnia), waking up during the night (middle insomnia), waking up too early and being unable to fall asleep again (late insomnia), and nonrestorative sleep at baseline. Factors known to be related to depression among older adults were included as covariates.

RESULTS

Our findings showed that each insomnia symptom subtype had distinct temporal effects on the onset of depression. It appeared that the effects of initial insomnia may take longer to emerge than indicated in previous studies. Middle insomnia and late insomnia had weak relationships with depression. Nonrestorative sleep predicted the onset of depression at every follow-up period.

CONCLUSIONS

We found that documenting the temporal effects of insomnia symptom subtypes helps both to classify individuals' insomnia symptoms and predict the onset of depression. We recommend taking temporal effects of insomnia symptom subtypes into account in future investigations and clinical practice.

Use of healthcare services and assistive devices among centenarians: results of the cross-sectional, international5-COOP study

OBJECTIVES

To measure the use of healthcare services and assistive devices by centenarians in five countries.

DESIGN

Cross-sectional study using a survey questionnaire.

SETTING

Community-dwelling and institutionalised centenarians living in Japan, France, Switzerland, Sweden and Denmark.

PARTICIPANTS

1253 participants aged 100 or in their 100th year of life, of whom 1004 (80.1%) were female and 596 (47.6%) lived in institutions.

MAIN OUTCOME MEASURES

Recent use of medical visits, nursing care at home, home-delivered meals, acute care hospital stays overnight, professional assessments such as sight tests, mobility aids and other assistive devices. A set of national healthcare system indicators was collected to help interpret differences between countries.

RESULTS

There was considerable variability in the healthcare services and assistive devices used by centenarians depending on their country and whether they were community-dwelling or institutionalised. In contrast to the relatively homogeneous rates of hospitalisation in the past year (around 20%), community-dwelling centenarians reported widely ranging rates of medical visits in the past 3 months (at least one visit, from 32.2% in Japan to 86.6% in France). The proportion of community-dwellers using a mobility device to get around indoors (either a walking aid or a wheelchair) ranged from 48.3% in Japan to 79.2% in Sweden. Participants living in institutions and reporting the use of a mobility device ranged from 78.6% in Japan to 98.2% in Denmark.

CONCLUSIONS

Our findings suggest major differences in care received by centenarians across countries. Some may result from the characteristics of national healthcare systems, especially types of healthcare insurance coverage and the amounts of specific resources available. However, unexplored factors also seem to be at stake and may be partly related to personal health and cultural differences.

[Survey on psychosomatic treatment options in geriatric clinical routine: state of the art]

BACKGROUND

Mental and physical disorders form a common body of experience and suffering in old age that can negatively influence aging. Experience and handling of age-associated functional impairments are challenging for multimorbid patients, their relatives and the healthcare providers involved. Among patients aged 70 years or older more than 50% suffer from psychopathological symptoms and 30-40% of geriatric inpatients have a psychosomatic or psychiatric comorbidity; however, despite this high prevalence of mental problems in older patients they are hardly ever treated and if treatment is offered it is carried out by specialists for somatic medicine. The aim of the present study of the working group on gerontopsychosomatics of the German Geriatric Society (DGG) was the evaluation of interdisciplinary co-management opportunities for geriatricians who treat inpatients with gerontopsychosomatic needs.

METHOD

Online survey among members of the DGG regarding experiences with interdisciplinary co-management of inpatients with gerontopsychosomatic needs.

RESULTS

The majority of the respondents were senior physicians in a department for geriatrics. While every second institution had access to a psychiatric consultation service, psychosomatic cooperation was only offered in every fifth department. Psychosomatic co-management was particularly required in connection with neurogeriatric problems.

CONCLUSION

There is need of gerontopsychosomatic co-management among geriatric inpatients; however, in comparison to gerontopsychiatric co-management the options are deficient and need to be strengthened.
