Our aim was to clarify the effect of aging on the coherence of electromyograms of plantar flexor pairs during bipedal stance and to clarify the relationship between coherence and center-of-mass acceleration (COMacc). The subjects were 16 adults and 18 older adults. Intra- and intermuscular coherence and phase analyses were used to analyze the muscle pairs of bilateral and unilateral plantar flexor muscle groups. The relationship between coherence value and anterior–posterior COMacc of the plantar flexor muscle pairs was also examined to determine whether the connectivity of the lower limb muscle pairs is functionally important. The older adults showed higher coherence in the frequency range of 0–4 Hz for muscle pairs than the younger adults. In phase analysis, the older adults showed a phase difference between bilateral heteronymous muscle pairs in the frequency range of 0–6 Hz, which was one of the characteristics not seen in the younger adults. Correlation analysis showed that all the muscle pairs were moderately correlated with COMacc in the older adults. Not only does aging affects the organization of the bilateral and unilateral postural muscle activity of the plantar flexors during bipedal stance, but such organization may also be related to the increased COMacc characteristics of older adults.

Purpose The purpose of this paper aims to examine differences in measures of and relationships between visitation and quality of life (QOL) among older and younger jailed adults. The authors also explored the contribution of visitation to QOL among adults in this setting. The authors anticipated fewer visits and lower QOL among older adults. Framed by psychosocial developmental theory, the authors also anticipated a larger effect in the relationship between visitation and QOL among older rather than younger adults and that visitation would contribute most readily to psychological QOL. Design/methodology/approach Cross-sectional data from a large US jail were used (n = 264). The authors described the sample regarding visitation and QOL measures among older (≥45) and younger adults (≤44) and examined differences in measures of and relationships between visitation and QOL using independent sample t-tests and bivariate analyses. The authors explored the contribution of visitation to psychological, social relationships, physical and environmental QOL among jailed adults using hierarchical multiple linear regression. Findings Older adults had fewer family visits and lower physical QOL than younger adults, disparities were moderate in effect (d range = 0.33–0.35). A significant difference also emerged between groups regarding the visitation and environmental QOL relationship (z = 1.66, p <0.05). Visitation contributed to variation in physical and social relationships QOL among jailed adults (Beta range = 0.19–0.24). Originality/value Limited research exists among jailed older adults and scholars have yet to examine the relationship between visitation and QOL among persons in these settings.

BACKGROUND An electronic personal health record (ePHR), also known as a personal health record (PHR), was broadly defined as an electronic application through which individuals can access, manage, and share their health information in a secure and confidential environment. Although ePHRs can benefit individuals as well as caregivers and healthcare providers, the use of ePHRs among individuals continues to remain low. The relationship between age and ePHRs use has been documented in previous studies, which indicated younger age was related to higher ePHRs use, and patients who are younger were more likely to use ePHRs. OBJECTIVE The current study aims to examine the relationship between human-technology interaction factors and ePHRs use among adults, and then compare the different effects of human-technology interaction factors on ePHRs use between younger adults (18-54 years old) and older adults (55 years of age and over). METHODS We analyzed the from the Health Information National Trends Survey (HINTS5, Cycle 3) collected from U.S. adults aged 18 years old and over in 2019. Descriptive analysis was conducted for all variables and each item of ePHRs use. Bivariate tests (Pearson test for categorical variable and F-test for continuous variables) were conducted over four age groups. Lastly, adjusting for socio-demographics and healthcare resources, a weighted multiple linear regression was conducted to examine the relationship between human-technology interaction factors and ePHRs use. RESULTS The final sample size was 1,363 and divided into two age groups: 18-54 years old and 55 years of age and older. The average level of ePHRs use was low (Mean=2.76, range=0-8). There is no significant difference on average ePHRs use between two age groups. Including clinical notes was positively related to ePHRs use in both groups: 18-54 years old (beta=0.28, P<0.01), 55 years old and above (beta=0.15, P<0.01). While accessing ePHRs using a smartphone app was only associated with ePHRs use among younger adults (beta=0.29, P<0.001), ease to understand health information in ePHRs was positively linked to ePHRs use only among older adults (beta=0.13, P<0.01). CONCLUSIONS This study found that including clinical notes was positively related to ePHRs use in both age groups, which suggested that including clinical notes as a part of ePHRs might improve the effective use of ePHRs among patients. Moreover, accessing ePHRs using a smartphone app was associated with higher ePHRs use among younger adults while ease of understanding health information in ePHRs was linked to higher ePHRs use among older adults. The design of ePHRs should provide the option of being accessible through mobile devices to promote greater ePHRs use among young people. For older adults, providers could add additional notes to explain health information recorded in the ePHRs.

AbstractBackground:The relevance of schema theory to psychopathology, in particular personality disorder, in younger adults is established. Investigations into the relevance of schema theory to older adults, however, is highly limited.Aims:To consider the relationship of schema modes to psychopathology in older adults and establish whether maladaptive schema modes are associated with unmet needs and that this relationship is mediated by the healthy adult mode of responding in this population.Method:One hundred and four older adults were recruited from an established database. Participants completed questionnaires assessing psychopathology, schema modes (YAMI: Young-Atkinson Mode Inventory) and basic psychological needs (BPNS: Basic Psychological Needs Scale – autonomy, competence and relatedness). Ninety-four responses were included after applying exclusion criteria.Results:The healthy adult schema mode was found to be associated with reduced psychopathology, and maladaptive child modes (angry and vulnerable child) to increased psychopathology. The healthy adult schema mode mediated the relationship between maladaptive child modes and needs satisfaction.Conclusions:As predicted by schema theory, the presence of one of the maladaptive child modes makes it difficult for an older individual to have their needs met, but the presence of healthy adult mode works to support this process.

Abstract Racial microaggressions are a common form of racial discrimination consisting of subtle or interpersonal slights. Racial microaggressions are linked to various kinds of psychological distress in younger adults, but have not been studied across the lifespan. We examined the relationship of racial microaggressions with psychological distress and anger rumination among younger and older adults identified as racial or ethnic minorities. We hypothesized that age would moderate the relationship between racial microaggressions and psychological distress and anger rumination, that is, the relationship would be weaker for older than for younger adults. Participants were recruited from Amazon Mechanical Turk and were compensated $1 for their participation. Preliminary tests of the hypotheses (N=220), using multiple regression analyses to test for moderation, failed to support the hypothesis that age would mitigate the impact of microaggressions on symptom severity. Both age and microaggressions were related to psychological distress and anger rumination, but contrary to prediction, older adults showed more exacerbation of distress in the face of microaggressions than younger adults. The results also differed by gender and ethnic groups, suggesting the importance of examining intersectional experiences of race, gender, and age in response to discrimination. These cross-sectional findings lend support to the importance of considering both subtle and overt discriminatory experiences in understanding the mental health challenges for minority groups in the U.S., but more work is needed to examine the intersection of ethnicity with other demographic variables, and to understand how the lifelong experiences of discrimination may shape older adults’ vulnerability, well-being, and resilience.

To achieve an appropriate level of reliance on an automated system, the operator must have an accurate system representation such that he/she is aware of the capabilities and limitations of the system. The appropriate use of an automated system can lead to optimal performance by the human-machine dyad. This study investigates the relationship between an accurate system representation and behaviors associated with human-automation interaction (e.g., reliance). Furthermore, age-related effects are also included in the investigation. A cooking memory aid (Cook's Collage) is used as an automated aid that keeps track of the ingredients used in a specific recipe. Participants are asked to interact with the automated device for 5 sessions (each on different days). Tasks are structured to simulate those in a real kitchen. Preliminary results suggest that that there is a different pattern of interaction with the aid as a function of age. Older adults tend to rely on the aid for real-time feedback while younger adults use the aid as a verification tool that they have executed the recipe as desired.

This study examined the psychological responses to an acute bout of aerobic exercise in sedentary older and younger adults. Eighteen young (mean age 24 years) and 15 older adults (mean age 64 years) completed a 20-min bout of stationary cycling at 65% of VO2peak. Affective responses were assessed before, during, and immediately after exercise. Participants’ exercise self-efficacy beliefs were assessed before and immediately after exercise. Both groups reported reduced pleasant feeling states and self-efficacy and increased physical exhaustion in response to acute exercise. Older adults also demonstrated a significant decrease in revitalization during and after cycling. Correlation analyses revealed that self-efficacy was related to feelings of fatigue during exercise and postexercise feelings of energy and fatigue. Both groups reported negative shifts in affect and self-efficacy during and 5 min after cycling. Acute affective and self-efficacy responses might influence one’s motivation to adopt and maintain regular physical activity. The relationship between these acute responses and physical activity behavior across the life span warrants future inquiry.

In our everyday lives, we negotiate complex and unpredictable environments. Yet, much of our knowledge regarding locomotion has come from studies conducted under steady-state conditions. We have previously shown that humans rely on the ankle joint to absorb energy and recover from perturbations; however, the muscle–tendon unit (MTU) behaviour and motor control strategies that accompany these joint-level responses are not yet understood. In this study, we determined how neuromuscular control and plantar flexor MTU dynamics are modulated to maintain stability during unexpected vertical perturbations. Participants performed steady-state hopping and, at an unknown time, we elicited an unexpected perturbation via rapid removal of a platform. In addition to kinematics and kinetics, we measured gastrocnemius and soleus muscle activations using electromyography and in vivo fascicle dynamics using B-mode ultrasound. Here, we show that an unexpected drop in ground height introduces an automatic phase shift in the timing of plantar flexor muscle activity relative to MTU length changes. This altered timing initiates a cascade of responses including increased MTU and fascicle length changes and increased muscle forces which, when taken together, enables the plantar flexors to effectively dissipate energy. Our results also show another mechanism, whereby increased co-activation of the plantar- and dorsiflexors enables shortening of the plantar flexor fascicles prior to ground contact. This co-activation improves the capacity of the plantar flexors to rapidly absorb energy upon ground contact, and may also aid in the avoidance of potentially damaging muscle strains. Our study provides novel insight into how humans alter their neural control to modulate in vivo muscle–tendon interaction dynamics in response to unexpected perturbations. These data provide essential insight to help guide design of lower-limb assistive devices that can perform within varied and unpredictable environments.

Inflammatory bowel diseases (IBD), consisting of Crohn’s disease and ulcerative colitis, are chronic remitting, relapsing inflammatory conditions of the gastrointestinal tract. While traditionally a disease of younger ages, the number of older adults with IBD is rising rapidly. Patients with IBD often experience geriatric syndromes at earlier ages. Older adults with IBD have poorer disease and treatment-related outcomes compared with younger adults with IBD. Applying the principles of geriatrics to understanding a chronic disease in older adults may improve health span. Better tools are needed to stratify IBD patients who are at high risk for adverse events. Frailty is a geriatric construct that may approximate biologic age. Frailty is a complex, multi-dimensional syndrome that leads to increased vulnerability to stress and decline of reserve across multiple physiologic systems. In this review, we present the leading conceptual models of frailty and discuss the applications of frailty in immune-mediated diseases. We also review chronic conditions where frailty has been applied successfully as a tool for risk stratification. Finally, we discuss in the detail the growing body of literature highlighting the relationship between frailty and IBD, the epidemiology of frailty in IBD, and ramifications of frailty in IBD.

Background and purpose Ankle function declines with age. The objective of this study was to investigate the association between ankle function and balance in older adults, with a focus on range of motion (ROM) and strength. Methods This was a cross-sectional study that included 88 healthy community-dwelling older adults. Ankle mobility was measured while bearing weight (lunge test) and not bearing weight. The plantar-flexor muscle strength was assessed using a hand-held dynamometer. Balance was measured in terms of dynamic balance and mobility (timed up and go test), monopodal and bipodal static balance with open and closed eyes (single-leg stand test and platform measures), and margins of stability (functional reach test). Linear correlation and multiple regression analyses were conducted with a 95% CI. Results and discussion Most participants had limited ankle mobility (n = 75, 86%). Weight-bearing ankle dorsiflexion ROM was the strongest predictor of dynamic balance and included general mobility and stability (Radj2 = [0.34]; β = [-0.50]). In contrast, plantar-flexor muscle strength was a significant predictor of static standing balance with open eyes (Radj2 = [0.16–0.2]; β = [0.29–0.34]). Overall, weight-bearing ankle dorsiflexion ROM was a more representative measure of balance and functional performance; however, a non-weight-bearing mobility assessment provides complementary information. Therefore, both measures can be used in clinical practice. Conclusion This study supports the concept that ankle mobility contributes to the performance of dynamic tasks, while the plantar-flexor muscle strength helps to develop a standing static balance. Identification of alterations in ankle function is warranted and may assist in the design of tailored interventions. These interventions can be used in isolation or to augment conventional balance training in order to improve balance performance in community-dwelling older adults.
