Designing ergonomic toilets and bathrooms for older adults: A study on anthropometric dimensions and recommendations.

AIMS: This study aimed to evaluate the ergonomic design of toilets and bathroom equipment for older adults using anthropometric measurements. DESIGN: This was a descriptive cross-sectional study. METHODS: Data were collected from 2,721 people aged ≥ 65 years in Turkey. Fourteen anthropometric measurements were evaluated. Body dimension characteristics were described using minimum, maximum, and arithmetic means and standard deviations and the 5th, 25th, 50th, 75th, and 95th percentiles. RESULTS: The measurements showed that companies generally do not design bathroom toilet equipment that is suitable for older adults. CONCLUSION: This study provides advice to designers and manufacturers on how to adapt their products to the bathroom according to users' body characteristics in order to increase person-environment fit for older people.

The factors affecting acceptance of gerontechnological products by older Turkish adults.

This study investigates the attitudes of Turkish older people towards the acceptance of gerontechnological products. It included a total of 871 older individuals aged 65 and above from seven geographical regions of Türkiye. A questionnaire adopted from previous studies was applied to collect the data. The use of products of the older people was studied under the headings of (i) home and daily life technology, (ii) communication technology, (iii) health technology and (iv) education and recreation technology. As a result of the factor analysis, 16 questions were classified under: "attitudes towards using technology (AUT), facilitating conditions (FC), perceived ease of use (PEU) and gerontechnology anxiety (GA)". The effect of independent variables on the use of gerontechnological products was investigated by one-way variance analysis, and the relationship between the use of neurotechnological products and the attitudes of the older people towards accepting gerontechnological products was investigated by correlation analysis. Region, place of residence, age, gender, education level, economic and health status were found to be important in use gerontechnological products (p < 0.05). There was a high correlation between product groups as well as between product groups and attitudes. Results can be utilized in the production and dissemination of gerontechnological products to increase the level of life quality of the older people.

Ergonomics and aging: A bibliometric analysis.

BACKGROUND: Despite the prevalence of publications focusing on the trends of the studies on ergonomics, the information of the aging focused studies within these publications is limited. OBJECTIVE: This study aims to provide general information regarding the trends of the studies on ergonomics and aging by using bibliometric analysis techniques and to provide a general view regarding to the development of this field. METHODS: The bibliometric data of the publications on ergonomics and aging were retrieved from the WOS Database and analysed by using the Bibliometrix extension of the R Packet Programme. For the visualisation of the bibliometric data, the Vosviewer programme was used. RESULTS: Analysis results of the 405 papers published between the years of 1979 and 2020 show that main themes were digital human modelling, design for all, workplace ergonomics, transport and vehicle design, kitchen design, human factors, care and vision in old age. CONCLUSIONS: The content of the studies on ergonomics and aging changed from basic elements of ergonomic design for older people to the investigations about computer-aided applications and the effect of the developing technology. Therefore, it can be said that the studies on ergonomics and aging are changing parallel to the development of the technology.

Determination of Workload, Work Stress and Related Factors in Nursing Home Workers during the COVID-19 Pandemic in Turkey.

COVID-19 has caused a major crisis all over the world. To manage this crisis, a fixed shift system was applied to nursing home staff in Turkey to protect nursing home residents from the COVID-19 pandemic. Staff were not allowed to leave the institution during fixed shifts. It is thought that this practice for the COVID-19 outbreak, while protecting nursing home residents on the one hand, increased the workload and related stress of nursing home staff on the other hand. To the best of our knowledge, there is no study examining the workload and stress caused by the COVID-19 pandemic for nursing home staff in Turkey. The aim of this study was to examine the level of workload and work stress experienced by staff working in nursing homes during the COVID-19 pandemic in Turkey. METHODS: A cross-sectional research design was used in the study. The sample of the study consisted of nursing home personnel working in nursing homes in the provinces of Istanbul, Ankara, Izmir and Antalya between October 2021 and January 2022. A personal information form and a workload and stress scale were used for collecting the data. Cluster analysis was performed with SPSS software. RESULTS: In total, 154 nursing home personnel participated in the study. A statistically significant difference was found between the mean age of the two clusters. The first cluster was described as "old" and the second as "young". Statistically significant and high values were found in the quantitative workload, qualitative workload, job organization, social work area and fatigue factors in the nursing home staff in the older participant cluster. CONCLUSION: The results of this study provide new information about the concepts of workload and work stress experienced during the COVID-19 pandemic in Turkey, which will serve as a guide for the management of future pandemics. Therefore, this study will contribute to the strategies to be followed in future pandemics in Turkey.

A comparison of the different anthropometric indices for assessing malnutrition among older people in Turkey: a large population-based screening.

OBJECTIVE: Due to an increase in aging worldwide, assessment of the nutritional status of older people becomes an important matter. Malnutrition in older people increases the risk of infections, disease period and hospitalization rates. This study aimed to compare the different anthropometric indices for detecting malnutrition among older people and comparing these indices among males and females to explain the possible differences. METHODS: In this cross-sectional study, 2721 aged 65 years and older in Turkey were enrolled. Anthropometric measurements weight, height, hip circumference (HC), and waist circumference (WC), abdominal circumference (AC), mid-upper arm circumference (MUAC), triceps skinfold thickness (TST), calf circumference (CC)) were measured. Body mass index (BMI), abdominal volume index (AVI), body roundness index (BRI) and body adiposity index (BAI), and waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR) indices were calculated using standardized formulas. The receiver operator characteristic curves (ROCs) were conducted in detecting the best anthropometric parameters. Adjusted odds ratios (OR) (stratified by sex) calculated for each anthropometric index. RESULTS: Participants with both BMI < 18.5 (1.1%) and BMI > 25 (80%) defined as the malnourished group and BMI of 18.5-24.99 (18.9%) defined as the normal group. In both sexes, the area under the curve (AUC) was > 0.7 for all anthropometric indices except WHR in females (AUC 0.66). BRI, WHR, WHtR, and AVI indices strongly predict the risk of malnutrition among both sexes. In males, the ORs were for BRI (6.83, 95% CI 5.39-8.66), WHR (6.43, 95% CI 5.9-6.9), AVI (2.02, 95% CI 1.86-2.12). In females, the ORs were for BRI (3.72, 95% CI 3.09-4.48), WtHR (2.63, 95% CI 1.3-3.5), and WHR (2.45, 95% CI 1.9-3.06). DISCUSSION: The presence of a large AUC in almost all anthropometric indices suggests that they can be used to assess the risk of malnutrition among older persons in both sexes.
