Self-Reported Reasons for Activity Limitations According to Age and Sex in Community-Dwelling Stroke Survivors

We examined self-reported reasons for activity limitations among Korean community-dwelling stroke survivors, focusing on age and sex differences. Data from 1547 stroke survivors who participated in the Korean National Health and Nutrition Examination Survey were analysed. The study outcomes were the self-reported reasons for activity limitations, encompassing general medical factors and stroke-related problems. These reasons were compared by age (<65 vs. ≥65 years) and sex using a complex-sample chi-square test. Stroke survivors reported different musculoskeletal, medical, and neurological problems as reasons for activity limitations, which differed by age and sex. Older stroke survivors reported more problems related to dementia, memory loss, auditory problems, back or neck problems, arthritis, or leg pain than younger survivors. Women reported more psychiatric problems, headaches or dizziness, back or neck problems, arthritis, gastrointestinal problems, and dental or oral problems than men. Older and female stroke survivors reported a higher mean number of reasons for activity limitations compared to younger and male survivors. Thus, a tailored approach considering age and sex is necessary to help stroke survivors with activity limitations in the Korean community. This study highlights the importance of considering demographic factors when designing interventions to improve their quality of life.

Precision and Personalized Medicine: How Genomic Approach Improves the Management of Cardiovascular and Neurodegenerative Disease

Life expectancy has gradually grown over the last century. This has deeply affected healthcare costs, since the growth of an aging population is correlated to the increasing burden of chronic diseases. This represents the interesting challenge of how to manage patients with chronic diseases in order to improve health care budgets. Effective primary prevention could represent a promising route. To this end, precision, together with personalized medicine, are useful instruments in order to investigate pathological processes before the appearance of clinical symptoms and to guide physicians to choose a targeted therapy to manage the patient. Cardiovascular and neurodegenerative diseases represent suitable models for taking full advantage of precision medicine technologies applied to all stages of disease development. The availability of high technology incorporating artificial intelligence and advancement progress made in the field of biomedical research have been substantial to understand how genes, epigenetic modifications, aging, nutrition, drugs, microbiome and other environmental factors can impact health and chronic disorders. The aim of the present review is to address how precision and personalized medicine can bring greater clarity to the clinical and biological complexity of these types of disorders associated with high mortality, involving tremendous health care costs, by describing in detail the methods that can be applied. This might offer precious tools for preventive strategies and possible clues on the evolution of the disease and could help in predicting morbidity, mortality and detecting chronic disease indicators much earlier in the disease course. This, of course, will have a major effect on both improving the quality of care and quality of life of the patients and reducing time efforts and healthcare costs.

Individual and population level impact of chronic conditions on functional disability in older adults

Background

It is unknown if the relationship between multimorbidity and disability differs by combinations of chronic conditions. The objective of our study was to elucidate how joint effect of different combinations of chronic conditions impact the five year risk of functional disability at the population level.

Methods

Participants ≥65 years from the Canadian Study of Health and Aging were assessed for functional disability measured using activities of daily living (ADL) and instrumental ADL (IADL), and the presence of conditions in five disease domains; cardiometabolic, neurological, sensory, musculoskeletal, and respiratory. Logistic regression was used to assess the relationship between each disease domain and incident ADL and IADL measured at five years of follow up and population attributable risk (PAR) was modeled for diseases domains that were significantly associated with disability. Results were stratified by sex and age (65–74 years, ≥75 years).

Results

There were 6272 participants free of ADL disability and 4571 participants free from IADL disability at baseline. For incident ADL, the greatest PAR values were 21.3 (9.8–32.8) for the cardiometabolic domain in males 65–74 years, 22.7 (4.7–40.8) for the musculoskeletal domain for females aged 65–74 years, and 11.2 (2.8–19.7) for the musculoskeletal domain in males ≥75 years. The PAR for the musculoskeletal, sensory, and neurological domains were similar in females ≥75 years(9.3–9.9). PAR values were lower but followed similar patterns for IADL disability.

Conclusion

The chronic disease domains which most strongly predicted incident ADLs and IADLs did not account for the greatest amount of disability at the population level.

Health Care Providers' Advice on Lifestyle Modification for Older Adults

OBJECTIVES

To describe the pattern of health care providers' advice on lifestyle modification to older adults, and identify correlates of receiving such advice.

DESIGN

Cross-sectional survey.

SETTING AND PARTICIPANTS

Data from the National Health and Nutrition Examination Survey study from 2007-2016 on adults ≥65 years (n = 3758) were analyzed.

METHODS

We estimated the weighted prevalence and correlates of receiving advice on the following lifestyle modifications: (1) increase physical activity, (2) reduce fat/calories, (3) control/lose weight, and (4) a combination of control/lose weight and physical activity. Data were analyzed according to level of comorbidity (number of chronic conditions including high blood pressure, high blood cholesterol, type 2 diabetes mellitus, coronary heart disease, and arthritis) and body mass index (BMI).

RESULTS

Physical activity was the most widely prescribed lifestyle modification, reported by 15.7% of older adults free of chronic conditions and 28.9%, 35.4%, and 52.6% of older adults with 1, 2, and ≥3 comorbidities. Advice on reducing fat/calories was reported by 9.2%, 18.5%, 26.3%, and 40.9% of older adults with 0, 1, 2, and ≥3 comorbidities, respectively, and advice on weight loss/control was reported by 6.5%, 19.1%, 20.8%, and 37.5%, respectively. The combination of advice on weight loss/control and physical activity was least commonly reported: 5.1%, 13.5%, 16.6%, and 32.0%, respectively. Overall, lifestyle modifications were more frequently advised to older adults who were overweight, obese, or Hispanic.

CONCLUSIONS AND IMPLICATIONS

In the United States, lifestyle modifications are not routinely recommended to older adults, particularly those free of chronic conditions, presenting a missed opportunity for chronic disease prevention and management. Among those advised to lose or manage weight, concurrent advice to increase physical activity is not consistently provided.
