The association of functional capacity with health-related behavior among urban home-dwelling older adults

The effect of social isolation on the cognitive ability of the oldest old in Chinese nursing homes in post-COVID-19: a moderated chain mediation model

Background

Both pre-or post-COVID-19, older adults residing in nursing homes are at significant risk for social isolation, which is negatively associated with cognitive ability. Currently, the elderly aged 80 years and older are the fastest-growing age group globally. The extent of social isolation within this group post-COVID-19 and its impact on cognitive abilities remain inadequately explored.

Objective

This research aimed to evaluate the prevalence of social isolation among the oldest old in Chinese nursing homes post-COVID-19 and to investigate the mediating and moderating roles of basic activities of daily living (BADL), depression, and subjective socioeconomic status in the relationship between social isolation and cognitive ability.

Methods

This cross-sectional study included 453 participants aged 80 years and older from 11 nursing homes in Ningbo, Zhejiang Province, China. Social isolation was assessed using the Lubben Social Network Scale-6 (LSNS-6), cognitive ability using the Mini-Mental State Examination (MMSE), BADL using the Barthel Index (BI), and depression using the Patient Health Questionnaire-9 items (PHQ-9). Mediation and moderation effects were statistically analyzed using SPSS 23.0 and PROCESS 3.5.

Results

The mean age of the study sample was 87.1 ± 3.8 years, among whom 60.3% (n = 273) were female, and 56.1% experienced social isolation, with 41.1% and 63.1% being isolated from family and friends, respectively. Social isolation indirectly affected cognitive ability through BADL and depression, respectively, and through the chain mediation effect of BADL and depression. Subjective socioeconomic status moderated the relationships between social isolation and BADL and between social isolation and depression. However, no moderating effect of subjective socioeconomic status was found between social isolation and cognitive ability.

Conclusion

This study deepens our understanding of the current state of social isolation and its mechanisms of action in the oldest old post-COVID-19 and provides a new basis for future public health policy development and related research.

Value of the 3-min walk test and its association with motor functions in older adults

BACKGROUND

The 3-min walk test (3MWT) has been used in the clinical setting.

OBJECTIVE

To present the 3MWT value and investigate its association with motor and respiratory functions of healthy older adults.

METHODS

Two hundred six older adults and 27 younger adults were enrolled. The 3MWT was assessed by the walking distance within 3 min. Knee extension muscle strength (KEMS), 5-repetition sit-to-stand (5 R-STS), Timed Up and Go (TUG), forced vital capacity (FVC), forced expiratory volume 1.0 (FEV1.0), maximal expiratory pressure (MEP), and maximal inspiratory pressure (MIP) were measured. The 3MWT distance was examined by age group (18-39, 60-69, 70-79, and 80-89 years). A multivariate regression analysis investigated the association between 3MWT and motor function test.

RESULTS

The 3MWT values in each age group were 273-385, 233-414, 93-351, and 171-345 m for men and 215-375, 220-349, 198-325, and 174-332 m for women respectively. The 3MWT values were correlated with age, body mass index (BMI), KEMS, 5 R-STS, TUG, FVC, FEV1.0, MEP, and MIP. On the multivariate regression analysis, 3MWT was significantly associated with BMI (standard beta = -0.18; 95% confidence interval [CI], -3.20 to 0.83), KEMS (standard beta = 0.37; 95% CI, 0.06-0.13), 5 R-STS (standard beta = -0.13; 95% CI, -5.70 to -0.13), and TUG (standard beta = -0.36; 95% CI, -17.15 to -7.73) in older adults (adjusted R2 = 0.47).

CONCLUSIONS

The 3MWT distance decreased with age and was associated with motor and respiratory functions. No range trends were observed among groups. Our findings suggest that 3MWT reflects functional capacity.

Satisfaction with Life, Subjective Well-Being and Functional Skills in Active Older Adults Based on Their Level of Physical Activity Practice

Studies about the influence of physical activity on life satisfaction, functional ability and subjective well-being in physically active older adults without cognitive impairment are very few for the moment. Therefore, the aim of this research was to evaluate the life satisfaction, functional skills and subjective well-being of physically active older adults based on the level of activity practiced. The IPAQ (International Physical Activity), CUBRECAVI and LSIA (Life Satisfaction Index) scales were tested for a sample of 397 Spanish older adults between 61 and 93 years of age (M = 69.65; SD = 4.71). The results showed that those who performed high physical activity obtained higher scores in functional skills (p < 0.01) and in the activities of daily living (p < 0.01). In addition, subjective well-being (p < 0.01) and the functional autonomy of older adults (p < 0.01) were related to the level of physical activity that they practiced. In conclusion, it could be said that the older adults with a high level of physical activity have more functional skills and less difficulties performing the activities of daily living, and that they value their autonomy and health better.

Association between out-of-home trips and older adults' functional fitness

AIM

To explore the purposes of older adults' out-of-home trips, and to investigate the association between the frequency of these trips and older adults' functional fitness.

METHODS

A total of 412 older adults in Taiwan were recruited from 2009 to 2010. Participants were asked to fill out questionnaires on out-of-home trips, and trained volunteers assessed the functional fitness of respondents using objective measures. Descriptive statistics, univariate analysis, multivariate regression analysis and canonical correlation analysis were then used to analyze the resulting data.

RESULTS

Results show that exercise is most frequently the purpose for going out at least once a day, and that parks are the most preferred places to visit. Sex and age are the significant variables explaining variance in older adults' flexibility and physical power, respectively. Canonical correlation analysis showed one significant variate pair (R(2)(c)  = 8.80) between the frequency of out-of-home trips (engaging in exercise and participating in religious activities) and fitness measure test scores including the chair stand, arm curl, 2-min step, and 8-foot up-and-go. The relationship did not exist for the back scratch, nor chair sit-and-reach test scores.

CONCLUSION

The present study provides empirical and objective evidence on older adults' purposes for taking out-of-home trips, and for the positive association between the frequency of these trips, and the muscular strength and cardiovascular endurance, but not flexibility, of older adults.

Older adults' transportation walking: a cross-sectional study on the cumulative influence of physical environmental factors

Background

The physical environment may play a crucial role in promoting older adults’ walking for transportation. However, previous studies on relationships between the physical environment and older adults’ physical activity behaviors have reported inconsistent findings. A possible explanation for these inconsistencies is the focus upon studying environmental factors separately rather than simultaneously. The current study aimed to investigate the cumulative influence of perceived favorable environmental factors on older adults’ walking for transportation. Additionally, the moderating effect of perceived distance to destinations on this relationship was studied.

Methods

The sample was comprised of 50,685 non-institutionalized older adults residing in Flanders (Belgium). Cross-sectional data on demographics, environmental perceptions and frequency of walking for transportation were collected by self-administered questionnaires in the period 2004-2010. Perceived distance to destinations was categorized into short, medium, and large distance to destinations. An environmental index (=a sum of favorable environmental factors, ranging from 0 to 7) was constructed to investigate the cumulative influence of favorable environmental factors. Multilevel logistic regression analyses were applied to predict probabilities of daily walking for transportation.

Results

For short distance to destinations, probability of daily walking for transportation was significantly higher when seven compared to three, four or five favorable environmental factors were present. For medium distance to destinations, probabilities significantly increased for an increase from zero to four favorable environmental factors. For large distance to destinations, no relationship between the environmental index and walking for transportation was observed.

Conclusions

Our findings suggest that the presence of multiple favorable environmental factors can motivate older adults to walk medium distances to facilities. Future research should focus upon the relationship between older adults’ physical activity and multiple environmental factors simultaneously instead of separately.

Exercícios físicos, força muscular e atividades de vida diária em mulheres idosas

O objetivo foi investigar as relações entre força muscular nos membros inferiores e nos superiores, prática de exercícios físicos e atividades de vida diária em mulheres idosas recrutadas na comunidade. Um mil quinhentas e trinta e oito idosas com idade média = 72,07 ± 5,46, renda familiar média = 3,59 ± 3,96 SM, sem déficit cognitivo sugestivo de demência. Foram submetidas a medidas de força de preensão manual e velocidade de marcha; a itens de autorrelato sobre prática regular de exercícios físicos; de desempenho de 13 atividades avançadas de vida diária (AAVD) de natureza social (ex: trabalhar, viajar e frequentar igreja) e de 3 atividades instrumentais de vida diária (AIVD) manejar dinheiro, fazer compras e usar transporte, 1.538 idosas com idade média = 72,07 ± 5,46, renda familiar média = 3,59 ± 3,96 SM, sem déficit cognitivo sugestivo de demência. Foram preditivos de pior desempenho em atividades de vida diária (AVD): baixa força muscular (OR = 2,48 para comprometimento da preensão e da marcha e 1,66 para comprometimento em qualquer dos critérios), baixa renda (OR = 2,46 e 2,45 para < 1 e para 1,1 a 3,0 SM) e sedentarismo (OR 2,08). A funcionalidade de mulheres idosas é afetada pelo envelhecimento fisiológico e por condições contextuais e de estilo de vida.

The effect of functional mobility and balance on health-related quality of life (HRQoL) among elderly people living at home and those living in nursing home

The present study examined the effect of functional mobility and balance on HRQoL among elderly people living at home and those living in nursing homes. The study included 122 elderly people aged 65 and over. With regard to the individuals whose socio-demographic data were collected in the scope of the study, balance and functional mobility levels were evaluated using the timed up and go test (TUG) and Berg balance scale (BBS); HRQoL was evaluated using the Nottingham health profile (NHP); physical independence in daily activities was evaluated using the Barthel index (BI); and basic mobility in daily life was evaluated using the Rivermead mobility index (RMI). Statistically significant differences were found between the TUG, BBS and NHP values of the elderly people living in a home environment and those living in nursing homes (p<0.05). However, no statistically significant difference could be found between the BI and RMI values (p>0.05). A statistically significant relationship was found between the NHP and TUG, RMI, BI and the use of assistive devices in daily life activities (p<0.05). It is thought that the inclusion of functional mobility and balance training in elderly care and rehabilitation programs would be useful for the elderly people to develop functional independence and in increasing their HRQoL.
