Sex differences in the association of physical function and cognitive function with life satisfaction in older age: The Rancho Bernardo Study

Satisfaction with Life and Nutritional Behaviour, Body Composition, and Functional Fitness of Women from the Kraków Population Participating in the "Healthy Active Senior" Programme

Pro-health behaviours are related to a person's personal resources. The aim of the study was to assess the relationship between satisfaction with life (SWL), nutritional behaviours, somatic indices, and functional efficiency of senior women. The research was conducted among 120 women aged 60-84 (Me = 65) participating in the "Healthy Active Senior" project at the University of Physical Education in Kraków. The Satisfaction with Life Scale (SWLS) and the proprietary validated questionnaire of nutritional behaviour were used. Body composition was assessed using the method of bioelectrical impedance (TANITA SC-330ST analyser), while physical fitness was evaluated via the Senior Fitness test (Fullerton Functional Fitness Test). Correlations between the variables were measured by implementing Spearman's R signed-rank correlation coefficients (with p < 0.05). Positive correlations between SWL and selected nutrition behaviours have been demonstrated, including eating 5-6 meals (p < 0.001) and drinking at least 2 litres of fluids a day (p = 0.023), consuming cereal products daily, including whole-grains (p = 0.001), avoiding alcoholic beverages (p = 0.030), and applying vitamin D supplementation (p = 0.010). At the same time, negative correlations between SWL and limiting the consumption of red as well as processed meats (p = 0.002), animal fats (p = 0.046), and the preference for vegetable oils in one's diet (p = 0.023) were shown. Significant correlations between satisfaction with life and two indicators of functional fitness were also confirmed: negative-with the variable '2.44-m Get-Up and Go' (p = 0.003); and positive-with the '2-Minute Step in Place' test (p = 0.034). The relationships between SWL and somatic indices did not reach the level of statistical significance. Among the women participating in the "Healthy Active Senior" programme, correlations between SWL and rational nutritional behaviours, as well as indices of functional fitness, were found (mostly positive), while the trends in these areas were not fully unambiguous, suggesting the validity of conducting further research.

Life Satisfaction Prevents Decline in Working Memory, Spatial Cognition, and Processing Speed: Latent Change Score Analyses Across 23 Years

Background

Within-person growth in life satisfaction (LS) can protect against declines in cognitive functioning, and, conversely, over time. However, most studies have been cross-sectional, thereby precluding causal inferences. Thus, we used bivariate dual latent change score modeling to test within-person change-to-future change relations between LS and cognition.

Method

Community adults completed in-person tests of verbal working memory (WM), processing speed, spatial cognition, and an LS self-report. Five waves of assessment occurred across 23 years.

Results

Reduction in LS predicted future decreases in spatial cognition, processing speed, and verbal WM (|d | = 0.150–0.354). Additionally, depletion in processing speed and verbal WM predicted a future decrease in LS (d  = 0.142–0.269). However, change in spatial cognition did not predict change in LS (|d | = 0.085).

Discussion

LS and verbal WM and processing speed predicted one another across long durations. Evidence-based therapies can be augmented to target LS and cognition.

Predictors and Importance of Social Aspects in Ikigai among Older Women

Ikigai is a unique Japanese concept that encompasses not only joy and happiness, but also the purpose and meaning of life. The purpose of this study was to explore the factors that contribute to Ikigai, an important concept in the health of older women, and to clarify the relationship between Ikigai and the enhancement of the social aspects of their health. The participants in this longitudinal study, conducted between October 2017 and February 2020, were physically healthy older women aged 65 years and above (N = 132). Physical function and social activity were used as predictors of Ikigai. In addition, willingness for new interactions was used to examine the social aspects of health. A causal model was created from these factors, and path analysis was performed. The results demonstrated that participating in numerous interpersonal activities was predictive of increased Ikigai, but physical function was not. In addition, Ikigai was found to affect the willingness for new interactions. Further, Ikigai could be related to the willingness for new interactions. To enhance the social aspects of older women’s health, it is necessary to focus on Ikigai.

Global and domain-specific life satisfaction among older adults with long-term spinal cord injury

OBJECTIVE

Although life expectancy after spinal cord injury (SCI) has increased, knowledge of life satisfaction and associated factors among older adults with long-term SCI is still very limited. The objective of this study was, therefore, to assess global and domain-specific life satisfaction among older adults with long-term SCI and investigate the association with sociodemographics, injury characteristics and secondary health conditions.

DESIGN

Cross-sectional cohort study. Data from the Swedish Aging with Spinal Cord Injury Study (SASCIS).

SETTING

Community settings in southern Sweden.

PARTICIPANTS

Seventy-eight individuals (32% women, injury levels C1-L3, American Spinal Injury Association Impairment Scale (AIS) A-D) mean age 68 years, mean time since injury 31 years.

INTERVENTIONS

Not applicable.

OUTCOME MEASURES

The Life Satisfaction Questionnaire (LiSat-11).

RESULTS

The participants were at least rather satisfied with most of the 11 life domains. They rated the lowest satisfaction with sexual life, activities of daily living and somatic health. Having a partner and being vocationally active was associated with greater satisfaction with life as a whole and with several other life domains. Participants with AIS D injuries were less satisfied with their somatic health than those with tetraplegia AIS A-C and paraplegia AIS A-C injuries. More secondary health conditions were negatively associated with satisfaction in five life domains.

CONCLUSION

Life satisfaction can be affected many years after SCI. The social context, participation in meaningful activities and minimizing secondary health conditions seem to be important for maintaining life satisfaction in older adults with a long-term injury.

The Life Satisfaction Index-A (LSI-A): Normative Data for a General Swedish Population Aged 60 to 93 Years

PURPOSE OF STUDY

To gain Swedish norm value for the Life Satisfaction Index-A (LSI-A) in a population 60-93+ years old stratified for sex and age and to relate these norm values with respect to number of chronic diseases and functional impairment.

MATERIALS AND METHODS

The study population included a random sample of 2656 men (45.7%) and 3159 (54.3%) women from the longitudinal national studies' "Good Aging in Skåne" (GÅS) and SNAC-B, both part of the Swedish National Study on Aging and Care (SNAC). Data on Neugartens Life Satisfaction Index-A (LSI-A), medical history, activities of daily life (ADL) and socio-demographics were collected through structured interviews and questionnaires.

RESULTS

Men scored significantly higher than women; 28.5, sd=6.9, and 27.3, sd=6.6, respectively, out of maximum 40 points. For both genders the scores decreased with age, mean score 6.0 points, lower for men and 7.1 points lower for women between 60 and 93+ years. The highest score was noted for healthy individuals where both men and women scored 29.5 points, sd=6.2. Increased number of chronic diseases and dependency in ADLs were associated with lower LS.

CONCLUSION

Norm values here presented may facilitate assessments and evaluation of life satisfaction in the general elder population and as reference values to clinical trials. Female sex, rising age, morbidity and impaired functional ability were all associated with impaired LS.

Perceived Resources and Satisfaction With Food-Related Life Among Ecuadorian Elderly

OBJECTIVE

To identify variables that explain satisfaction with food-related life in Ecuadorian elderly people.

DESIGN

Stratified random sampling with proportional affixation within each retirement home was conducted based on the rate of rurality, gender, age, and living circumstances.

SETTING

Retirement homes in Guayaquil, Ecuador.

PARTICIPANTS

The sample consisted of 817 elderly people of both genders (47.5% women; mean age 73.7 years; SD 7.45 years; range 60-101 years) registered in retirement homes located in Guayaquil, Ecuador.

MAIN OUTCOME MEASURES

Satisfaction With Life scale, satisfaction with food-related life (SWFL), and 22 food-related perceived resources.

ANALYSIS

Generalized linear models.

RESULTS

Gender, food consumption expenditure, satisfaction with economic situation, unhealthy days, family importance, food-related lifestyles, food neophobia, and the sum of 22 resources were found to be associated with SWFL. In addition, the Pearson bivariate correlation between the Satisfaction With Life scale and SWFL was .38 (P < .01).

CONCLUSIONS

Perceived resources contributed to SWFL and the greatest satisfaction with life was observed among older adults who were more satisfied with their food.

The effect of Tai Chi on quality of life in male older people: A randomized controlled clinical trial

BACKGROUND AND AIM

Physical activity can improve the mental and physical functioning of older people. This study investigated the impact of Tai Chi exercise on the quality of life of older men.

METHODS

This randomized controlled clinical trial was conducted on 132 older men in an urban area of Iran. The subjects were randomly assigned into two groups: a Tai Chi intervention group and a control group (n = 66 per group). Quality of life was evaluated using the Leiden-Padua quality of life questionnaire before and after the intervention. Data analysis was performed using analytical statistics via the SPSS software.

RESULTS

After eight weeks of Tai Chi exercise, the mean scores of quality of life in different areas demonstrated a statistically significant difference between the two groups (p < 0 0.05).

CONCLUSION

This study illustrated that the 8-week Tai Chi intervention had a positive effect on quality of life in older men.

Different indicators of socioeconomic status and their relative importance as determinants of health in old age

Background

Socioeconomic status has been operationalised in a variety of ways, most commonly as education, social class, or income. In this study, we also use occupational complexity and a SES-index as alternative measures of socioeconomic status. Studies show that in analyses of health inequalities in the general population, the choice of indicators influence the magnitude of the observed inequalities. Less is known about the influence of indicator choice in studies of older adults. The aim of this study is twofold: i) to analyse the impact of the choice of socioeconomic status indicator on the observed health inequalities among older adults, ii) to explore whether different indicators of socioeconomic status are independently associated with health in old age.

Methods

We combined data from two nationally representative Swedish surveys, providing more than 20 years of follow-up. Average marginal effects were estimated to compare the association between the five indicators of SES, and three late-life health outcomes: mobility limitations, limitations in activities of daily living (ADL), and psychological distress.

Results

All socioeconomic status indicators were associated with late-life health; there were only minor differences in the effect sizes. Income was most strongly associated to all indicators of late-life health, the associations remained statistically significant when adjusting for the other indicators. In the fully adjusted models, education contributed to the model fits with 0–3% (depending on the outcome), social class with 0–1%, occupational complexity with 1–8%, and income with 3–18%.

Conclusions

Our results indicate overlapping properties between socioeconomic status indicators in relation to late-life health. However, income is associated to late-life health independently of all other variables. Moreover, income did not perform substantially worse than the composite SES-index in capturing health variation. Thus, if the primary objective of including an indicator of socioeconomic status is to adjust the model for socioeconomic differences in late-life health rather than to analyse these inequalities per se, income may be the preferable indicator. If, on the other hand, the primary objective of a study is to analyse specific aspects of health inequalities, or the mechanisms that drive health inequalities, then the choice of indicator should be theoretically guided.
