Pet Insects May Improve Physical Performance and Sleep in Community-Dwelling Frail Elderly People with Chronic Diseases: A Single-Arm Interventional Pilot Study

Purpose

Animal-assisted intervention (AAI) is an effective intervention that improves the mental and physical health. However, few have examined the efficacy of pet insects as a form of AAI for prefrail and frail elderly. This study aimed to ascertain the effects of pet insects on physical performance and psychological health in community-dwelling frail elderly individuals with a chronic disease.

Patients and Methods

This study was an 8 week prospective single-arm interventional pilot study that enrolled prefrail and frail community-dwelling adults aged 70 years and older, all of whom had a chronic disease and attended a daycare facility. Pet insects and appropriate equipment were provided, and supporting programs were used to educate participants about how to rear the insects and how to get close to them. Pre- and post-interventional physical and psychological functions were evaluated.

Results

A total of 23 subjects (mean age, 82.78 years) were enrolled in the final analysis. The timed up-and-go-test (TUG) was used to measure functional mobility, and grip strength was used as a measure of muscle strength; both showed significant changes after the 8-week intervention (Δ = -0.35±0.73 sec, P = 0.034; and Δ = 0.73±0.99 kg, P = 0.002, respectively). In addition, the insomnia severity index (ISI) and average sleep duration improved significantly (Δ = -2.91±5.64, P = -0.021; and Δ = 0.87±1.98, P = 0.047, respectively). There were no significant changes in the results of other psychometric tests. Logistic regression analysis using the forward stepwise selection method revealed that the baseline ISI score and the absence of other comorbidities were significantly associated with the probability of positive changes in both the TUG and HS tests after the intervention.

Conclusion

Pet insects may be an effective and easily applicable type of AAI, which improves physical function and sleep in prefrail and frail elderly individuals.

Factors Affecting the Deterioration of the Physical Health Status of Taxi Drivers by Age Group

With the rapidly aging population, taxi drivers are aging at a fast pace, and competition in the taxi industry is intensifying due to the emergence of various transportation platforms. A descriptive secondary data study was conducted (on a total of 936 subjects) to determine the factors affecting the deterioration of taxi drivers’ physical health status (PHS) according to their age group. The increased incidence of chronic diseases and cognitive decline among taxi drivers aged 55−64 years had the greatest influence on the deterioration of their PHS. Driver obesity was more likely to be related to deterioration of the PHS in the drivers aged 55−64 years (OR: 2.459, <0.001) and 35−54 years (OR: 2.133, <0.001). Among the financial factors, a driver’s income and their number of dependent family members were correlated with the deterioration of the PHS for drivers aged 55 years or over. Therefore, chronic diseases, obesity and cognitive decline were related with deterioration of the physical health status. This suggests that attention should be paid to healthcare policies not only for the elderly aged over 65 years but also those aged 50 to 64 years, i.e., middle-aged people at the beginning of the transition to old age.

Effect of Severe External Airborne Agents' Exposure on Dementia

The impact of occupational and environmental exposure to external airborne agents on cognitive function, especially in incidence of dementia, is understudied. The present study was conducted to elucidate the association between severe external airborne agents' exposure and incidence of dementia among an elderly population and to explore the effects of exposure to severe external airborne agents on preclinical dementia using the screening test of dementia. From the National Health Insurance Service-Health Screening Cohort (NHIS-HealS, 2002-2015), 514,580 participants were used for data analysis. We estimated the standardized incidence ratio (SIR) according to the exposure to external airborne agents. Of the total participants (n = 514,580), 1340 (0.3%) experienced severe external airborne agents exposure, and 26,050 (5.1%) had been diagnosed with dementia. The SIRs (95%CI) of dementia in Alzheimer's disease, vascular dementia, dementia in other diseases, and unspecific dementia were 1.24 (1.01-1.49), 0.88 (0.37-1.32), 1.16 (0.01-2.77), and 0.69 (0.36-1.02), respectively. The risk of testing positive in the dementia screening significantly increased with exposure to severe external airborne agents after adjusting for all confounding variables. This study found that exposure to severe external airborne agents is a potential risk factor for dementia, especially in Alzheimer's disease. It is essential to create international awareness regarding the effect of airborne agents' exposure on dementia.
