Midlife as a Pivotal Period in the Life Course: Balancing Growth and Decline at the Crossroads of Youth and Old Age

Association between health literacy and self-management among middle-aged women: A systematic review

OBJECTIVE

We aimed to review and synthesize the literature on the association between health literacy (HL) and self-management in middle-aged women aged 35-64 years and examine the definitions and measurements of HL.

METHODS

Eleven electronic databases were used for searching specific terms. Experimental and non-experimental studies in English or Korean were included based on the eligibility criteria. Two authors independently conducted study selection, data extraction, and methodological quality assessment.

RESULTS

One experimental and 13 non-experimental studies were included. Of the 11 studies that defined HL, nine conceptualized it as reflecting multidimensional HL. Four studies measured HL capturing all dimensions of the concept (i.e., accessing, understanding, appraising, and applying) and two studies used context-specific HL measurements. Women with greater HL challenges generally had lower self-management context, process, and outcomes across the health continuum.

CONCLUSIONS

Enhancing HL is a critical strategy for improving self-management in middle-aged women. Future research should investigate the effectiveness of HL interventions on self-management considering multidimensional definitions and measures of HL.

PRACTICE IMPLICATIONS

Health professionals should be alert to middle-aged women's HL and implement HL interventions that provide them with opportunities to access, understand, analyze, and utilize health-related information to effectively improve HL and engage in self-management.

Cross-sectional associations between patterns and composition of upright and stepping events with physical function: insights from The Maastricht Study

INTRODUCTION

Age-related declines in physical functioning have significant implications for health in later life. Physical activity (PA) volume is associated with physical function, but the importance of the pattern in which PA is accumulated is unclear. This study investigates associations between accelerometer-determined daily PA patterns, including composition and temporal distribution (burstiness) of upright and stepping events, with physical function.

METHODS

Data was from participants who wore an activPAL3 accelerometer as part of The Maastricht Study. Exposures included a suite of metrics describing the composition and the temporal distribution (burstiness) of upright and sedentary behaviour. Physical function outcomes included the six-minute walk test (6MWT), timed chair-stand test (TCST), grip strength (GS), and SF-36 physical functioning sub-scale (SF-36pf). Multivariable linear regression models were used to assess associations, adjusting for covariates including overall PA volume (daily step count).

RESULTS

Participants(n = 6085) had 6 or 7 days of valid data. Upright and stepping event metrics were associated with physical function outcomes, even after adjusting PA volume. Higher sedentary burstiness was associated with better function (6MWT, TCST, and SF-36pf), as was duration and step volume of stepping events (6MWT, TCST, GS, and SF-36pf), step-weighted cadence (6MWT, TCST, and SF-36pf). Number of stepping events was associated with poorer function (6MWT, GS, and SF-36pf), as was upright event burstiness (SF-36pf). Associations varied according to sex.

CONCLUSION

Our study reveals that diverse patterns of physical activity accumulation exhibit distinct associations with various measures of physical function, irrespective of the overall volume. Subsequent investigations should employ longitudinal and experimental studies to examine how changing patterns of physical activity may affect physical function, and other health outcomes.

Cross-sectional associations between temporal patterns and composition of upright and stepping events with physical function in midlife: Insights from the 1970 British Cohort Study

INTRODUCTION

Age-related decline in physical functioning has significant implications for health in later life but declines begin earlier in midlife. Physical activity (PA) volume is associated with physical function, but the importance of the pattern in which PA is accumulated is unclear. This study investigates associations between patterns of PA accumulation, including the composition, variation, and temporal distribution of upright and stepping events, with physical function in midlife.

METHODS

Participants (n = 4378) from the 1970 British Cohort Study wore an activPAL3 accelerometer on the thigh for 7 consecutive days. Exposure measures included a suite of metrics describing the frequency, duration, and composition of upright events, as well as the duration and volume (total steps) of stepping events. In addition, patterns of accumulation of upright and sedentary events were examined including how fragmented/transient they were (upright-to-sedentary transition probability [USTP]) and their burstiness (the tendency for events to be clustered together followed by longer interevent times). Physical function outcomes included grip strength (GS), balance, and SF-36 physical functioning subscale (SF-36pf). Cross-sectional analyses included multivariable linear regression models to assess associations, adjusting for covariates including overall PA volume (mean daily step count).

RESULTS

Higher upright event burstiness was associated with higher GS, and higher USTP was associated with lower GS. Duration and step volume of stepping events were positively associated with SF-36pf in females. Step-weighted cadence was positively associated with SF-36pf and balance. Contradictory findings were also present (e.g., more transient stepping events were associated with better GS) particularly for GS in males. Inconsistencies between sexes were observed across some associations.

CONCLUSION

Our study reveals that diverse patterns of PA accumulation exhibit distinct associations with various measures of physical function in midlife, irrespective of the overall volume. Contradictory findings and inconsistency between sexes warrant further investigation. Patterns of PA accumulation, in addition to volume, should be considered in future PA research. Longitudinal studies are required to determine whether a given volume of activity accumulated in different patterns, impacts associations between PA and health outcomes.

Mothering While Sick: Poor Maternal Health and the Educational Attainment of Young Adults

At a time when educational attainment in young adulthood forecasts long-term trajectories of economic mobility, better health, and stable partnership, there is more pressure on mothers to provide labor and support to advance their children's interests in the K-12 system. As a result, poor health among mothers when children are growing up may interfere with how far they progress educationally. Applying life course theory to the National Longitudinal Study of Adolescent to Adult Health to investigate this possibility, we found that young adults were less likely to graduate from college when raised by mothers in poor health, especially when those mothers had a college degree themselves. Young people's school-related behaviors mediated this longitudinal association. These findings extend the literature on the connection between education and health into an intergenerational process, speaking to a pressing public health issue-rising morbidity among adults in midlife-and the reproduction of inequality within families.

Midlife diseases of despair and cardiometabolic risk: testing shared origins in adolescent psychopathology

BACKGROUND

Rising midlife mortality in the United States is largely attributable to 'deaths of despair' (deaths from suicide, drug poisonings, and alcohol-related diseases) and deaths from cardiometabolic conditions. Although despair- and cardiometabolic-related mortality are increasing concurrently, it is unclear whether they share common developmental origins. We tested adolescent psychopathology as a potential common origin of midlife diseases of despair and cardiometabolic risk.

METHODS

Participants (N = 4578) were from the National Longitudinal Study of Adolescent to Adult Health, a nationally representative cohort followed from adolescence to early midlife. Adolescent psychopathology included depression, anxiety, eating disorders, PTSD, conduct disorder, and ADHD at ages 11-18. Diseases of despair (suicidality, substance misuse, pain, and sleep problems) and cardiometabolic risk (hypertension, hyperlipidemia, high-risk waist circumference, diabetes, and cardiovascular conditions) were multi-modally measured at ages 33-43.

RESULTS

At midlife, adolescents who experienced psychopathology exhibited more indicators of despair-related diseases and cardiometabolic risk (IRRs = 1.67 [1.46-1.87] and 1.13 [1.04-1.21], respectively), even after accounting for demographics, adolescent SES, and adolescent cognitive ability. Associations were evident for internalizing and externalizing conditions, and in a dose-response fashion. In mediation analyses, low education explained little of these associations, but early-adult substance use explained 21.5% of psychopathology's association with despair-related diseases. Midlife despair-related diseases and cardiometabolic risk co-occurred within individuals (IRR = 1.12 [1.08-1.16]). Adolescent psychopathology accounted for 8.3% of this co-occurrence, and 16.7% together with adolescent SES and cognitive ability.

CONCLUSIONS

Adolescent psychopathology precedes both diseases of despair and cardiometabolic risk. Prevention and treatment of psychopathology may mitigate multiple causes of poor midlife health, reducing premature mortality.

Adult Development and Associated Health Risks

Much has been learned about adult development in recent decades. Adults go through stages of development (emerging adulthood, young adulthood, middle adulthood, post-retirement, and very old age) with certain challenges at each stage. Viewing patients through a developmental lens is part of providing patient-centered care. Knowing the prominent issues, stressors, and risks at each stage of development is important in understanding patients. This knowledge can help customize medical advice to patients regarding obesity, disability, sleep, substance use, relationships, and age-related declines. This paper summarizes an updated view of adult development and discusses its relevance to health risks and patient-centered care practices at different stages.

Identifying Specific Gaps in Knowledge of Aging and Examining Its Relation to Biases Toward Older Adults

Accurate aging knowledge is key to reducing ageist attitudes that impact older adult well-being. We first investigated how aging knowledge and negative and positive age-bias indirectly expressed via aging knowledge responses were related to an explicitly negative ageism measure. We then identified specific gaps in the aging knowledge of emerging adults and middle-aged adults. More negative ageism correlated with less aging knowledge overall and in psychological and social, but not biological, domains. Negative ageism correlated with negative age-bias, but not positive age-bias, expressed via aging knowledge responses. Knowledge of aging was poorest regarding social and psychological aspects of aging and best regarding biological aging. Middle-aged adults had slightly, but significantly, more accurate aging knowledge and less negative age-bias than emerging adults; positive age-bias did not differ by age-group. These results suggest that effectiveness of anti-ageism educational interventions may be enhanced if focused on improving knowledge of social and psychological aging.

Limited English Proficiency Is Not Associated With Poor Postoperative Outcomes or Follow-Up Rates in Patients Undergoing Breast Reduction Mammoplasty - A Single Institution Retrospective Cohort Study

INTRODUCTION

Limited English Proficiency (LEP) status has been associated with worse patient outcomes on a variety of metrics.

METHODS

A retrospective review of all bilateral breast reduction mammoplasty patients at our institution between 2015 and 2019 was performed. Data collected include patient demographics, language status, interpreter usage, complications, and follow-up clinic/emergency department visits. Patients were grouped into high and low follow-up cohorts by median follow-up. Bivariate testing and regression modeling were used for analysis.

RESULTS

A total of 1023 patients were included. Average age and body mass index (BMI) were 37.7 years and 31.7 kg/m2. All LEP (21%) patients used interpreters. There were 590 individuals in the low follow-up and 433 in the high follow-up group. Those in low follow-up were younger, with lower BMI, and were more likely to use Medicaid. Prevalence of diabetes and postoperative emergency department visits were higher in the high follow-up cohort. There were no significant differences in race/ethnicity, smoking status, and interpreter use between groups. Poisson modeling demonstrated that presence of complications is associated with a 0.435 increase in the number of clinic visits and a 1-y increase in age is associated with a 0.006 increase (P < 0.001). Interpreter use was not significantly associated with postoperative clinic visits. Multivariable regression modeling demonstrated BMI and diabetes to be significantly associated with incidence of any complication (odds ratio: 1.08 & 2.234; P < 0.001 &P = 0.01, respectively).

CONCLUSIONS

LEP status was not associated with worse postoperative outcomes or follow-up length in patients undergoing breast reduction mammoplasty. This may be due to interpreter use and effective patient education.

Socioeconomic inequalities in deaths of despair: Age heterogeneity in Canada's working age population

PURPOSE

Although prior literature documented socioeconomic inequalities in deaths of despair among working age population, it is unclear whether and how (a) the link between socioeconomic status and deaths of despair differs by age (b) each measure of socioeconomic status has independent effects on deaths of despair. This study aims to reduce these knowledge gaps.

METHODS

Using data from a large scale nationally representative linked dataset (2011 Canadian Census Health and Environment Cohorts), this study employed Fine-Gray subdistribution hazard models to estimate the link between socioeconomic status and deaths of despair due to suicide, drug overdose, and alcoholic liver disease among working age population (N = 4,076,530). Age stratified analysis was conducted to examine age heterogeneity.

RESULTS

Socioeconomic status, such as housing tenure, employment status, household income, and education level, was associated with deaths of despair among working age population. Age differences in the association between socioeconomic status and deaths of despair were found. While education level was pronounced for deaths of despair for younger adults, a combination of socioeconomic status was significantly associated with deaths of despair for those in late adulthood.

CONCLUSIONS

Socioeconomic inequalities in deaths of despair are manifest among Canadian working age population. This study lends support the social and health policies aimed at reducing gaps in mortalities.

Negative Aging Stereotypes: Fear of Dependency Impact on Anxiety and Depression in Middle and Older Adults, Examined by Gender

Negative stereotypes of aging, such as dependency, tend to paint a picture of older adults as frail or a burden on society. This study aimed to explore the relationship between the Fear of Dependency Scale and anxiety and depression, evaluating gender, age, and physical health as moderators. Findings suggest that age moderated the relationship between fear of dependency and depression and anxiety in women, with middle-aged women reporting the highest levels of depression and anxiety. Similarly, poor physical health in women with high fear of dependency was related to higher levels of depression and anxiety. Fear of dependency was related to higher levels of depression, but not anxiety in men. Age did not moderate the relationship between fear of dependency and mental health measures, but physical health did moderate the relationship. Men with poor perceived health and a high fear of dependency reported higher levels of depression.

COVID-19 Pandemic-Related Stress and Subjective Well-Being Across Age: The Mediating Role of Social Resources

Stress associated with the COVID-19 pandemic and the measures implemented to prevent its spread dramatically shifted our social networks, interactions, and contexts, all of which influence the assessment of one's subjective well-being (SWB). Drawing on data collected from 1,318 adults between April and May 2020, we used structural equation modeling to analyze the relationship between pandemic-related stress and SWB (life satisfaction, positive affect, negative affect), and examined how these relationships vary across age. Pandemic-related stress was associated with lower life satisfaction and higher negative affect. However, no evidence of age moderation emerged. Subsequent analysis examined different aspects of social resources as potential mediating variables. Loneliness fully mediated the relationship between stress and life satisfaction, while social support demonstrated evidence of partial mediation. Further, loneliness and social support partially mediated the relationship between stress and negative affect. Findings suggest that pandemic-related stress impacts SWB, and social resources help explain these impacts.

Examining reactivity to the measurement of physical activity and sedentary behavior among women in midlife with elevated risk for cardiovascular disease

OBJECTIVES

To estimate the extent of reactivity to measurement of physical activity (PA) and sedentary behavior among women in midlife with elevated risk for cardiovascular disease (CVD).

DESIGN

Secondary analysis of a 10-day observational study of PA and sedentary behavior.

MAIN OUTCOME MEASURES

PA (steps, minutes of light PA, total minutes of moderate-to- vigorous PA [MVPA]) and percent time in sedentary behavior per day were assessed using ActiGraph GT3X tri-axial accelerometers in 75 women in midlife with elevated CVD risk (e.g. hypertension; MAge = 51.61, MBMI = 34.02 kg/m2). Two-level multilevel models were used to test for evidence of reactivity, with the addition of random effects to test for evidence of individual differences in observed trends.

RESULTS

All outcomes showed linear trends across days (ps < 0.001), though this masked what appeared to be meaningful dropoff after Day 1 or Day 2 (with little difference between subsequent days; srs ranging from 0.15 to 0.32). The random effect was significant only for percent time in sedentary behavior (χ2[1] = 10.40, p = 0.02).

CONCLUSIONS

Consistent small to medium effects were found for all PA and sedentary behavior outcomes, underscoring the importance of considering measurement reactivity in populations with elevated CVD risk.

Stress, depression, and anxiety: psychological complaints across menopausal stages

Introduction

With the number of menopausal women projected estimated to reach 1.2 billion by 2030 worldwide, it is critically important to understand how menopause may affect women's emotional well-being and how many women are affected by this. This study aimed to explore (i) the relationship between psychological complaints (depression, anxiety, poor memory) across different menopausal stages and (ii) investigate the correlation between resilience, self-efficacy, and perceived stress levels, with psychological complaints and whether this was associated with menopausal stage and/or age.

Methods

287 respondents completed the Menopausal Quality of Life (MenQoL), Perceived Stress Scale (PSS-10), Brief Resilience Scale (BRS), and General Self-efficacy (GSE) scales. Parametric and non-parametric analysis were used to analyse how bothered women were by self-reported poor memory and feelings of depression and anxiety, alongside perceived stress, resilience, and self-efficacy between women in different menopausal stages using STRAW criteria. The association between protective factors (self-efficacy and resilience) and psychological complaints was analysed with partial correlation analysis controlling for menopausal stages and/or age.

Results

A significant difference was found between the levels of perceived stress, and how bothered women were by feelings of depression and anxiety between early-perimenopausal and post-menopausal women. However, with the inclusion of age as a covariate, menopausal stage no longer predicted the level of self-reported stress and anxiety in menopausal women. There was also no difference between poor self-reported memory, or of self-efficacy or resilience between women in different menopausal stages. However, self-efficacy and resilience were associated with how bothered women were by feelings of depression and anxiety, and the experience of stress. Stress was the only variable to be associated with poor self-reported memory independent of age and/or menopausal status.

Discussion

Early perimenopausal women experienced the highest level of stress and were more severely bothered by feelings of depression and anxiety, with the poorest overall self-reported psychosocial quality of life. Post-menopausal women, however, reported to have similar experiences as premenopausal women. Age explained the associations between menopausal stage, stress and anxiety, but not between depression and different menopausal stages. Resilience and self-efficacy were associated with psychological complaints independent of menopausal stage and age, suggesting that therapies focusing on increasing resilience and self-efficacy may be beneficial to help target these psychological complaints at any time.

Emotion regulation shows an age- and sex-specific moderating effect on the relationship between chronic stress and cognitive performance

Despite the extensive knowledge about the effects of chronic stress on cognition, the underlying mechanisms remain unclear. We conducted a cross-sectional moderation analysis on a population-based sample of 596 adults to examine the age- and sex-specific role of emotion regulation (ER) in the relationship between chronic stress and cognitive performance using validated self-report questionnaires. While women showed no direct or moderated relationship between stress and cognition, men displayed a distinct age-related pattern where stress was negatively associated with poorer cognitive performance at older ages, and the onset of this relationship was detected earlier in men with ER problems. These results showed that suppression of emotions and lack of executive control of ER amplify the negative consequences of chronic stress and suggest that there are sex-specific differences in the decline of ability to cope with long-term exposure to stressors.

"Am I Too Old to Pursue a Degree?" Ageism at Midlife in a Community College Setting

Adults who are beginning or returning to finish a degree program at midlife face different challenges than do their younger counterparts whose college experience begins at 18 years of age. We suspect that internalized ageism, defined as self-directed ageist attitudes and behaviors, may hinder nontraditional age students along with the experience of individual and institutional ageism. To evaluate this notion, we assessed the prevalence of self-reported positive and negative ageist behaviors in 205 students (M = 21.95, SD = 7.28, age range: 16-52 years) and 29 faculty (M = 49.55, SD = 11.07, age range: 33-71 years) in a community college in southeast Louisiana in the spring of 2019. All completed the Relating to Older People Evaluation (ROPE; Cherry & Palmore, 2008) and an open-ended question on how they viewed middle-aged students. Quantitative analyses indicated that students' ROPE scores exceeded those of the faculty and more positive than negative ageist behaviors were reported. Qualitative analyses revealed mostly positive expectations of middle-aged students among narrative responses to the open-ended question. As a follow-up, 10 nontraditional age students were individually interviewed in person to obtain an in-depth assessment of their community college experience. Strong evidence of internalized, individual, and institutional ageism were evident in their responses. Their narratives also revealed atypical life experiences and rich details of faculty-level and institutional-level policies that supported or hindered their academic progress. Implications of these data for addressing ageism on multiple levels in higher education are considered.

Multiple Myeloma in Young Patients: A Scoping Review

Data on the disease course, presenting features, outcomes, and prognosis of younger patients with multiple myeloma (MM) are lacking. Younger patients with MM have historically been considered to have better outcomes primarily based on better tolerance of treatment and lack of medical comorbidities, but the specific age range of this population has not been uniformly defined. Given the lack of consistent data reporting in patients considered to be young MM patients, we performed a scoping review to highlight the research currently available to start drawing conclusions about these patients and highlight unmet areas of need to focus on further investigation. We searched Embase, Cochrane Central Register of Controlled Trials, CINAHL Plus, Web of Science, and the OVID version of MEDLINE including broad terms that embody the concept of young patients with MM. Our final review included 201 studies which were then categorized according to age group, number of patients, outcomes, and comparators to older patients, along with location and database when available. We have chosen to categorize 3 age groupings: <50: young adults with MM (YA MM), 50 to 65: mid-life adults with multiple myeloma (ML MM) and 65+: older adults with multiple myeloma (OA MM). This review demonstrates the heterogeneity that exists in defining and describing young patients with MM, highlights the lack of studies specifically addressing the unique needs of younger patients, and emphasizes areas of future research unique to this population.

Affective reactivity to daily stressors and immune cell gene expression in the MIDUS study

Affective reactivity to stress is a person-level measurement of how well an individual copes with daily stressors. A common method of measuring affective reactivity entails the estimation of within-person differences of either positive or negative affect on days with and without stressors present. Individuals more reactive to common stressors, as evidenced by affective reactivity measurements, have been shown to have increased levels of circulating pro-inflammatory markers. While affective reactivity has previously been associated with inflammatory markers, the upstream mechanistic links underlying these associations are unknown. Using data from the Midlife in the United States (MIDUS) Refresher study (N = 195; 52% female; 84% white), we quantified daily stress processes over 10 days and determined individuals' positive and negative affective reactivities to stressors. We then examined affective reactivity association with peripheral blood mononuclear cell (PBMC) gene expression of the immune-related conserved transcriptional response to adversity. Results indicated that individuals with a greater decrease in positive affect to daily stressors exhibited heightened PBMC JUNB expression after Bonferroni corrections (p-adjusted < 0.05). JUNB encodes a protein that acts as a transcription factor which regulates many aspects of the immune response, including inflammation and cell proliferation. Due to its critical role in the activation of macrophages and maintenance of CD4+ T-cells during inflammation, JUNB may serve as a potential upstream mechanistic target for future studies of the connection between affective reactivity and inflammatory processes. Overall, our findings provide evidence that affective reactivity to stress is associated with levels of immune cell gene expression.

Midlife Health in Britain and the US: A comparison of Two Nationally Representative Cohorts

Background

Older adults in the United States (US) have worse health and wider socioeconomic inequalities in health compared to Britain. Less is known about how health in the two countries compares in midlife, a time of emerging health decline, including inequalities in health.

Methods

We compare measures of smoking status, alcohol consumption, obesity, self-rated health, cholesterol, blood pressure, and glycated haemoglobin using population-weighted modified Poisson regression in the 1970 British Cohort Study (BCS70) in Britain (N= 9,665) and the National Longitudinal Study of Adolescent to Adult Health (Add Health) in the US (N=12,297), when cohort members were aged 34-46 and 33-43, respectively. We test whether associations vary by early- and mid-life socioeconomic position.

Findings

US adults had higher levels of obesity, high blood pressure and high cholesterol. Prevalence of poor self-rated health, heavy drinking, and smoking was worse in Britain. We found smaller socioeconomic inequalities in midlife health in Britain compared to the US. For some outcomes (e.g., smoking), the most socioeconomically advantaged group in the US was healthier than the equivalent group in Britain. For other outcomes (hypertension and cholesterol), the most advantaged US group fared equal to or worse than the most disadvantaged groups in Britain.

Interpretation

US adults have worse cardiometabolic health than British counterparts, even in early midlife. The smaller socioeconomic inequalities and better overall health in Britain may reflect differences in access to health care, welfare systems, or other environmental risk factors.

The social readjustment rating scale: Updated and modernised

The Social Readjustment Rating Scale, originally devised in 1967 by Holmes and Rahe, measures the impact of life events stress. At the time, the SRRS advanced its field of research by standardising the impact of stress with a set of independently derived weights called 'life change units' (LCUs) for 43 life events found to predict illness onset. The scale has been criticised for being outdated, e.g. "Mortgage over $10,000" and biased, e.g. "Wife begin or stop work". The aim of this cross-sectional survey study is to update and improve the SRRS whilst allowing backwards compatibility. We successfully updated the SRRS norms/LCUs using the ratings of 540 predominantly UK adults aged 18 to 84. Moreover, we also updated wording of 12 SRRS items and evaluated the impact of demographics, personal experience and loneliness. Using non-parametric frequentist and Bayesian statistics we found that the updated weights were higher but broadly consistent with those of the original study. Furthermore, changes to item wording did not affect raters' evaluations relative to the original thereby ensuring cross-comparability with the original SRRS. The raters were not unduly influenced by their personal experiences of events nor loneliness. The target sample was UK rather than US-based and was proportionately representative regarding age, sex and ethnicity. Moreover, the age range was broader than the original SRRS. In addition, we modernised item wording, added one optional extra item to the end of the scale to evaluate the readjustment to living alone and identified 3 potential new items proposed by raters. Backwards-compatibility is maintained.

Suitability of the Attitudes to Aging Questionnaire Short Form for Use among Adults in Their 50s: A Cross-Sectional e-Survey Study

This cross-sectional e-survey study examines the suitability (reliability and validity) of the 12-item Attitudes to Aging Questionnaire Short Form (AAQ-SF) for use among adults in their 50s. The AAQ-SF instrument was originally designed to capture subjective perceptions of physical change, psychosocial loss, and psychological growth by asking people aged 60 and beyond how they feel about growing older. Our sample comprised 517 people residing in three Canadian provinces. Respondents completed the Attitudes to Aging Questionnaire Short Form, the Rosenberg Self-Esteem Scale, and a short sociodemographic profile. Our findings replicate the original AAQ-SF structure for physical change, psychosocial loss, and psychological growth, with a promising internal consistency range for the third subscale. In our sample, psychological growth is best represented as 'Self' and 'Generativity', with a particularly greater capacity to explain variations in scores for item 18 and item 21. Physical change and psychosocial loss scores strongly differed based on perceived health and chronic illness presence. Psychosocial loss and psychological growth were moderately correlated with two aspects of self-esteem. We relate these patterns of findings within the context of prevailing growth and development theory and their perceived implications within the context of COVID-19 and post-pandemic life.

Autism through midlife: trajectories of symptoms, behavioral functioning, and health

BACKGROUND

This study describes change in autism symptoms, behavioral functioning, and health measured prospectively over 22 years. Most studies tracking developmental trajectories have focused on autism during childhood, although adulthood is the longest stage of the life course. A robust understanding of how autistic people change through midlife and into older age has yet to be obtained.

METHODS

Using an accelerated longitudinal design with 9 waves of data, developmental trajectories were estimated from adolescence through midlife and into early old age in a community-based cohort (n = 406). The overall aim was to determine whether there were age-related increases or decreases, whether the change was linear or curvilinear, and whether these trajectories differed between those who have ID and those who have average or above-average intellectual functioning. Subsequently, the slopes of the trajectories were evaluated to determine if they differed depending on age when the study began, with the goal of identifying possible cohort effects.

RESULTS

There were significant trajectories of age-related change for all but one of the measures, although different measures manifested different patterns. Most autism symptoms improved through adulthood, while health worsened. An inverted U-shaped curve best described change for repetitive behavior symptoms, activities of daily living, maladaptive behaviors, and social interaction. For these measures, improved functioning was evident from adolescence until midlife. Then change leveled off, with worsening functioning from later midlife into early older age. Additionally, differences between autistic individuals with and without ID were evident. Although those who have ID had poorer levels of functioning, there were some indications that those without ID had accelerating challenges in their aging years that were not evident in those with ID - increases in medications for physical health problems and worsening repetitive behaviors.

CONCLUSIONS

Meeting the needs of the increasingly large population of autistic adults in midlife and old age requires a nuanced understanding of life course trajectories across the long stretch of adulthood and across multiple domains. Given the heterogeneity of autism, it will be important not to generalize across sub-groups, for example those who are minimally verbal and those who have above-average intellectual functioning.

A Study on the effect of lifestyle educational intervention based on the theory of planned behavior on promoting quality of life of middle-aged women

The present study aimed to determine the effect of lifestyle educational intervention based on the theory of planned behavior on promoting the quality of life of middle-aged women. The present quasi-experimental study examined 80 middle-aged women and randomly divided them into two groups (intervention and control). Data collection tools included the demographic information questionnaire, the Health Promoting Lifestyle Profile-II (HPLP-II), the 12-Item Short-Form Health Survey (SF-12), and the author-developed questionnaire based on constructs of the theory of planned behavior. Data were collected via WhatsApp twice (before and three months after the educational intervention). Five 45-minute training sessions were held for the intervention group and a 60-minute session for a family member regarding physical activity and spiritual growth over two months via WhatsApp. Data were analyzed using SPSS, and the results were considered significant at a statistical level (p < .05). The implementation of the educational intervention significantly increased the mean scores of quality of life, physical activity and spiritual growth, knowledge regarding physical activity and spiritual growth, attitude toward physical activity and spiritual growth, subjective norms toward spiritual growth, perceived behavioral control for physical activity, and behavioral intention to perform physical activity and spiritual growth in the intervention group in comparison with the control group. The educational intervention, which was designed based on constructs of the theory of planned behavior, was influential in promoting the lifestyles and quality of life of middle-aged women. Therefore, it is suggested to use the educational program of the present study in addition to other middle-age health care.

Long-term function, body composition and cardiometabolic health in midlife former athletes: a scoping review

While sports medicine has traditionally focused on recovering from injury and returning athletes to sport safely after injury, there is a growing interest in the long-term health of athletes. The purpose of this scoping review was to (1) summarise the literature (methodologies and findings) on physical function, body composition and cardiometabolic health in midlife (age 40-65 years) former competitive athletes compared with non-athlete controls, (2) identify areas for future study in long-term health in athletes and (3) determine outcomes that could be evaluated in a future systematic review(s). We searched PubMed, CINAHL, Web of Science and SPORTDiscus for studies published between 2000 and 2022 evaluating former athletes and controls on physical function, body composition and/or cardiometabolic measures using MeSH terms. We identified 20 articles that met our criteria. Outcomes varied considerably across studies, most of which were cross-sectional and evaluated only males. Limited data suggest that former endurance athletes have leaner body compositions, higher aerobic capacity and better cardiometabolic indicators than controls; former athletes who maintain higher physical activity (ie, self-reported exercise) are healthier than those who do not; and former team sport athletes, who have higher injury prevalence, may have poorer functional performance than controls who were recreationally active in college. Studies rarely evaluated functional performance, did not control for prior injury or diet and seldom assessed current physical activity levels. Future research should include females and evaluate sex differences, control for prior sports-related injury(ies), quantify physical activity, use standardised outcome measures including performance-based functional assessments and incorporate longitudinal designs.

Insights into caregivers' perspectives on abuse of older persons: a qualitative exploratory study in southwest Nigeria

OBJECTIVE

Elder abuse perpetration by caregivers is well documented, particularly from the perspectives of older persons who are victims of abuse. However, few studies in Nigeria have examined the caregivers' viewpoints. This study explored the perception about the perpetration of elder abuse perpetration among adults aged 18-59 in Nigeria.

DESIGN

Using a qualitative descriptive approach, this study generated data through four in-depth interviews (IDIs) and eight focus group discussions (FGDs). All IDIs and FGDs were audiorecorded, transcribed coded and analysed thematically with Atlas ti.

SETTING

Rural and urban communities in Oyo State, southwest Nigeria.

PARTICIPANTS

73 purposively selected adults who had provided care for or lived near an older person in southwestern Nigeria.

RESULTS

Types of elder abuse identified were verbal (grumbling, insulting, snapping and shouting at older persons), physical (shoving and beating an older person) and neglect (refusing to render assistance, cook or carry out chores for an older person). Participants believed relatives of older persons were unlikely to perpetrate abuse compared with neighbours and paid caregivers. They, however, felt that people whose parents had maltreated them during childhood could perpetrate abuse especially neglect of their older parents. Identified possible provocation for abuse included an unkempt physical appearance, poor attitude or offensive behaviour in the older person. Participants further opined that lack of communal unity or mutual respect, loss of moral ideals and religious values and erosion of cultural values could also provide an environment where elder abuse can thrive.

CONCLUSION

Interventions for community-level prevention of elder abuse can leverage on the identified moral and religious values, relationship and cultural factors for successful deployment.

Ecological Momentary Assessment of Midlife Adults' Daily Stress: Protocol for the Stress Reports in Variable Environments (STRIVE) App Study

BACKGROUND

Daily stressors are associated with cognitive decline and increased risk of heart disease, depression, and other debilitating chronic illnesses in midlife adults. Daily stressors tend to occur at home or at work and are more frequent in urban versus rural settings. Conversely, spending time in natural environments such as parks or forests, or even viewing nature-themed images in a lab setting, is associated with lower levels of perceived stress and is hypothesized to be a strong stress "buffer," reducing perceived stress even after leaving the natural setting. However, many studies of daily stress have not captured environmental contexts and relied on end-of-day recall instead of in-the-moment data capture. With new technology, these limitations can be addressed to enhance knowledge of the daily stress experience.

OBJECTIVE

We propose to use our novel custom-built Stress Reports in Variable Environments (STRIVE) ecological momentary assessment mobile phone app to measure the experience of daily stress of midlife adults in free-living conditions. Using our app to capture data in real time will allow us to determine (1) where and when daily stress occurs for midlife adults, (2) whether midlife adults' daily stressors are linked to certain elements of the built and natural environment, and (3) how ecological momentary assessment measurement of daily stress is similar to and different from a modified version of the popular Daily Inventory of Stressful Events measurement tool that captures end-of-day stress reports (used in the Midlife in the United States [MIDUS] survey).

METHODS

We will enroll a total of 150 midlife adults living in greater Indianapolis, Indiana, in this study on a rolling basis for 3-week periods. As those in underrepresented minority groups and low-income areas have previously been found to experience greater levels of stress, we will use stratified sampling to ensure that half of our study sample is composed of underrepresented minorities (eg, Black, American Indian, Hispanic, or Native Pacific Islanders) and approximately one-third of our sample falls within low-, middle-, and high-income brackets.

RESULTS

This project is funded by the National Institute on Aging from December 2022 to November 2024. Participant enrollment began in August 2023 and is expected to finish in July 2024. Data will be spatiotemporally analyzed to determine where and when stress occurs for midlife adults. Pictures of stressful environments will be qualitatively analyzed to determine the common elements of stressful environments. Data collected by the STRIVE app will be compared with retrospective Daily Inventory of Stressful Events data.

CONCLUSIONS

Completing this study will expand our understanding of midlife adults' experience of stress in free-living conditions and pave the way for data-driven individual and community-based intervention designs to promote health and well-being in midlife adults.

Diversity of network communication mode and interpersonal interactions: Relationship with social support and well-being

Social interactions today expand beyond in-person interactions. Therefore, it is important to recognize that social interactions can occur with social network members across multiple communication modes (in-person, phone, and online). The current study explored the role that social support plays in the relationship between mode frequency (in-person, phone, and online), network communication mode diversity (breadth and evenness of communicating with network members via different communication modes), and well-being (positive affect, stress, and loneliness) from the 3-year UCNET (UC Berkley Social Networks Study, N = 1159) dataset. The study contained samples for two age groups (cohorts) - 21-31 year-olds and 50-70 year-olds, which also allowed for an exploration of age differences in these relationships. Longitudinal random-intercept cross-lagged panel models (RI-CLPM) showed a high degree of stability over the 3 years for all variables. Cross-sectional structural equation mediation models showed that social support mediated the relationships of mode frequency (in-person, phone, and online) and network communication mode diversity with well-being (more positive affect and less loneliness and stress). Age differences were found in the relationship between frequency of communication modes and social support, in that the frequency of communication mode was positively related to social support for younger adults, but not for middle-aged/older adults. Current findings provided future research directions geared toward further understanding of the mode frequency and network communication mode diversity constructs and how they relate to various psychosocial outcomes.

Effects of a digital self-control intervention to increase physical activity in middle-aged adults

The goal of this study was to test the effects of a 7-week digital self-control intervention to increase physical activity using a two-arm randomized controlled trial. The self-control treatment group showed greater increases in self-reported physical activity (MET's) than the comparison group. Both groups significantly increased their daily steps and self-control. Participants with higher initial levels of conscientiousness were better able to increase their daily steps during the intervention and participants who increased more in self-control showed greater increases in MET's. These moderation effects were more pronounced in the self-control treatment group as compared to the comparison group. This study shows that the effects of physical activity interventions may depend on personality characteristics and outcomes may be improved when individual differences are considered and targeted.

Midlife Transition Experiences of South Asian Immigrant Women in Canada: A Qualitative Exploration

BACKGROUND

South Asians make up a significant portion of the immigrant population in Canada, and a large portion of them are in their midlife. To improve the midlife transition of South Asian immigrant women, it is necessary to understand their lived experiences.

PURPOSE

Guided by the transition theory, this study investigates the midlife experiences of South Asian immigrant women in Canada.

METHODS

Twenty-two South Asian midlife, immigrant women were recruited to participate in this study from the Greater Toronto Area, Ontario, Canada. This study consisted of one asynchronous online focus group with 12 participants and ten one-on-one telephone interviews. Qualitative content analysis was guided by transition theory.

RESULTS

South Asian immigrant women experienced many different transitions in their midlife in Canada. These transitions included changes in their (a) lifestyle, (b) career, (c) family, (d) physical health, (e) mental health, (f) social, (g) environment, and (h) personal development. Women actively managed their transitions using strategies such as exercise, socialization, counseling, and religion. Women expressed the need for social, community, and governmental support to facilitate their midlife transitions.

CONCLUSION

To promote healthy midlife transition, governments need to create better employment policies to facilitate immigrant women settlement, transferring skills, and re-employment in Canada. In addition, health care and community services to promote physical and mental health should be emphasized.

How do middle-aged patients and their healthcare providers manage multimorbidity? Results of a qualitative study

BACKGROUND

It is particularly difficult for healthcare providers to deliver optimal medical care to multimorbid middle-aged persons because patients' professional activities, family lives, and other everyday responsibilities hinder them from making necessary lifestyle changes. Our aim was to find out how patients and healthcare providers view and manage the problems of dealing with multimorbidity in middle age.

METHODS AND FINDINGS

This qualitative study consisted of three steps. First, we conducted semi-structured in-depth interviews with 15 purposively sampled middle-aged persons living with multimorbidity to explore the experiences of care in the context of their leisure time, family lives, and work. Second, further individual interviews were carried out to find out the views of 14 healthcare providers. Third, the results of the interviews with patients and healthcare providers were presented to and discussed with four healthcare providers at an interprofessional workshop. Interview data was coded using an inductive-deductive approach and analyzed using content analysis. While patients reflected on challenges in several life domains, healthcare providers differentiated between levels of challenges. Both shared recommendations for better care including i) helping patients cope, ii) providing relief in activities of daily living, iii) continuity of care, iv) interprofessional cooperation, v) health promotion/prevention, vi) expansion of health services and vii) general system-level changes. Furthermore, the healthcare provider workshop highlighted the importance of increasing patient-centeredness, reducing complexity through a care coordinator and promoting interprofessional cooperation/networking.

CONCLUSIONS

To further improve the care of patients living with multimorbidity, barriers to managing multiple chronic conditions and facilitators to navigating complex care scenarios should be explored not only for people beyond working age, but for individuals in their mid-life specifically.

Training effects of set- and repetition-interval rest time on recumbent-boxing exercise: Could virtual reality improve further?

This study examined the influence of set-interval and repetition-interval rest time of virtual reality (VR) boxing game in supine-lying posture. Fifty healthy middle-aged adults were randomly assigned into VR and non-VR groups to perform six different exercise protocols with varying set-interval and repetition-interval rest times (S0R0, S0R1/3, S0R2/3, S40R0, S40R1/3, and S40R2/3). Analysis on the non-VR group showed significant differences between exercise protocols for average heart rate (p < 0.001), maximum ventilation volume (p < 0.001), respiratory quotient (p < 0.001), oxygen pulse (p < 0.001), and excess post-exercise oxygen consumption (EPOC) (p = 0.003). VR appeared to have no further improvement on physical training effects in middle-aged adults, while the participants reported negative experience that might be associated with the over-exertion. Future study might need to explore game design elements that can accommodate high-exertion exercises.

Derivation and external validation of a risk score for clinically important declines in health and function among two longitudinal cohorts of women in the mid-life

OBJECTIVES

Women in mid-life often develop chronic conditions and experience declines in physical health and function. Identifying factors associated with declines provides opportunity for targeted interventions. We derived and externally validated a risk score for clinically important declines over 10 years among women ages 55-65 using the Physical Component Summary Score (PCS) of the SF-36.

DESIGN

Derivation and validation of a risk score.

SETTING

Two longitudinal cohorts from sites in the USA were used.

PARTICIPANTS

Women from the Study of Women's Health Across the Nation (SWAN) and women from the Women's Health Initiative (WHI) Observational Study and/or clinical trials.

OUTCOME MEASURES

A clinically important decline over 10 years among women ages 55-65 using the PCS of the SF-36 predictors was measured at the beginning of the 10 years of follow-up.

RESULTS

Seven factors-lower educational attainment, smoking, higher body mass index, history of cardiovascular disease, history of osteoarthritis, depressive symptoms and baseline PCS level-were found to be significant predictors of PCS decline among women in SWAN with an area under the curve (AUC)=0.71 and a Brier Score=0.14. The same factors were associated with a decline in PCS in WHI with an AUC=0.64 and a Brier Score=0.18. Regression coefficients from the SWAN analysis were used to estimate risk scores for PCS decline in both cohorts. Using a threshold of a 30% probability of a significant decline, the risk score created a binary test with a specificity between 89%-93% and an accuracy of 73%-79%.

CONCLUSIONS

Seven clinical variables were used to create a valid risk score for PCS declines that was replicated in an external cohort. The risk score provides a method for identifying women at high risk for a significant mid-life PCS decline.

Age Specificity of Effects of Health Problems on Drinking Reduction: A Lifespan Developmental Analysis

Older adult drinking poses a growing public health concern, especially given the ongoing aging of the United States population. As part of a larger lifespan developmental project contrasting predictors of drinking reductions across different periods of adulthood, we tested age differences in effects of health problems on drinking declines across young adulthood, midlife, and older adulthood. We predicted these effects to be developmentally specific to midlife and older adulthood. We also tested moderation by alcohol use disorder (AUD) symptomatology and by indices of sociodemographic disadvantage (sex and race/ethnicity). Analyses used data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), leveraging NESARC's vast age range (18-90 + ; N = 43,093) and two waves of longitudinal data. Multiple-group cross-lag models tested differences across age groups in cross-lag paths between health problems and alcohol consumption. As hypothesized, health problem effects on drinking reductions were developmentally specific to midlife and older adulthood. However, models testing moderation by AUD symptomatology showed that these adaptive effects of health problems on drinking reductions did not extend to those with one or more AUD symptoms. Little evidence was found for moderation by sex or race/ethnicity. Findings support the notion of health concerns as a pathway to drinking reduction that increases in importance across the adult lifespan. However, given the moderation by AUD symptoms, findings also highlight a need to understand barriers to health-related pathways to drinking reduction among relatively severe midlife and older adult drinkers. These findings hold implications for lifespan developmental tailoring of clinical, public health, and policy interventions.

Exploring food insecurity and multimorbidity in Indian socially disadvantaged people: cross-sectional findings from LASI, 2017-18

OBJECTIVES

The present study aimed to examine the association of multimorbidity status with food insecurity among disadvantaged groups such as Scheduled Castes (SCs), Scheduled Tribes (STs), and Other Backward Class (OBCs) in India.

METHOD

The data for this study was derived from the first wave of the Longitudinal Ageing Study in India (LASI),2017-18, focusing on 46,953 individuals aged 45 years and over who belong to SCs, STs, and OBCs groups. Food insecurity was measured based on the set of five questions developed by the Food and Nutrition Technical Assistance Program (FANTA). Bivariate analysis was performed to examine the prevalence of food insecurity by multimorbidity status along with socio-demographic and health-related factors. Multivariable logistic regression analysis and interaction models were used.

RESULTS

The overall prevalence of multimorbidity was about 16% of the study sample. The prevalence of food insecurity was higher among people with multimorbidity compared to those without multimorbidity. Unadjusted and adjusted models suggested that people with multimorbidity were more likely to be food insecure than people without multimorbidity. While middle-aged adults with multimorbidity and men with multimorbidity had a higher risk of food insecurity.

CONCLUSION

The findings of this study suggest an association between multimorbidity and food insecurity among socially disadvantaged people in India. Middle-aged adults experiencing food insecurity tend to reduce the quality of their diet and consume a few low-cost, nutritionally deficient meals to maintain caloric intake, putting them again at risk for several negative health outcomes. Therefore, strengthening disease management could reduce food insecurity in those facing multimorbidity.

Executive function performance in middle-aged adults

Executive functions have been widely studied in the extreme of ages, but studies in middle-aged adults remain largely neglected. Education and gender are known to influence cognitive performance; however, their effect on executive function in middle-aged adults remains unclear.

Objective

The study aimed to observe the effect of hierarchy of educational qualifications (graduate, postgraduate, and PhD) and gender on various executive function tests across middle-aged adults with or without comorbidity.

Methods

A total of 66 middle-aged individuals volunteered for the study (mean age=48.45±5.45 years; 20 graduates, 28 postgraduates, and 18 PhD; 36 males and 30 females; 38 healthy adults and 28 adults with comorbidities). Each subject performed a test assessing short-term memory, spatial working memory, and multitasking abilities on the Cambridge Neuropsychological Test Automated Battery with rest periods in no specific order of tests. Key parameters of cognitive tests were analyzed for differences in educational qualifications (ANOVA), gender (t-test), and the effect of comorbidity as a covariate (ANCOVA).

Results

PhDs performed significantly better (p<0.05) in multitasking than graduates and had superior visuospatial working memory (fewer errors). Differences in simultaneous matching abilities, lower incongruence cost and multitasking cost were statistically significant in healthy females than in males.

Conclusion

On considering adults with comorbidity, those with higher educational attainment retained the ability to multitask compared to their healthy counterparts, which was not seen in the group with lower educational attainment. Thus, higher educational attainment attenuated the influence of comorbidities and deterioration of executive functions in general in middle-aged adults.

The need to change: Is there a critical role of midlife adaptation in mental health later in life?

Although late-life depression (LLD) is a serious health problem and more common than dementia in people over 60, it is underdiagnosed and undertreated. The cognitive-emotional etiology of LLD is particularly poorly understood. This is in contrast to the now extensive literature from psychology and cognitive neuroscience on the characteristics of emotionally healthy aging. This research consistently shows a change in emotional processing in older adults that is modulated by prefrontal regulation. Lifespan theories explain this change in terms of neurocognitive adaptation to limited opportunities and resources that typically occur in the second half of life. Epidemiological data on an increase in well-being after a low point around age 50 suggest that the majority of people seem quite capable of making this adaptation, even though empirical evidence for a causal modulation of this so called 'paradox of aging' and for the role of the midlife dip is still lacking. Intriguingly, LLD is associated with deficits in emotional, cognitive, and prefrontal functions similar to those shown to be crucial for healthy adaptation. Suspected causes of these deficits, such as white matter lesions or affective instability, become apparent as early as midlife when internal and external changes as well as daily challenges set in. Based on these findings, we propose that some individuals who develop depression at older ages may not have been able to successfully implement self-regulatory adaptation at midlife. Here, we review the current evidence and theories on successful aging, the neurobiology of LLD, and well-being across the lifespan. Drawing on recent advances in lifespan theories, emotion regulation research, and cognitive neuroscience, we propose a model of successful versus unsuccessful adaptation that emphasizes the increasing need for implicit habitual control and resource-based regulatory choice during midlife.

Physical and Behavioral Factors Associated With Improvement in Physical Health and Function Among US Women During Midlife

Importance

Women often experience physiological and functional changes in their health during midlife. Identifying women who have clinically important improvements in physical health and function and evaluating the factors associated with these improvements can identify intervention targets at midlife.

Objective

To identify factors associated with improvements in physical health and function among women during midlife.

Design, Setting, and Participants

Participants were part of the Study of Women's Health Across the Nation (SWAN), a diverse cohort of US women early in midlife, and followed up annually for up to 21 years between 1996 and 2017. Analyses were based on visit 8 (2004-2006) through visit 15 (2015-2017). Statistical analysis was conducted from October 2021 to March 2023.

Exposures

Sociodemographic indicators, health status measures, and comorbidities measured at visit 8.

Main Outcomes and Measures

The main outcome was a clinically important (≥5 points) improvement in the physical component score (PCS) of the 36-item Short-Form Health Survey between visit 8 and visit 15.

Results

Of the 1807 women (at visit 8: mean [SD] age, 54.5 [2.7] years; 898 [50%] White participants) in SWAN who qualified for analysis, 265 (15%) experienced a clinically important improvement in PCS over a median of 11.1 years (IQR, 10.9-11.4 years). Factors associated with improvement in PCS included no financial strain (odds ratio [OR], 1.73; 95% CI, 1.18-2.52), no sleep disturbances (OR, 1.43; 95% CI, 1.05-1.96), no osteoarthritis (OR, 1.42; 95% CI, 1.01-1.99), and having a higher physical activity score (OR, 1.17; 95% CI, 1.00-1.37) as assessed at visit 8. Women who had a higher PCS at visit 8 (OR, 0.84; 95% CI, 0.83-0.86), who had a higher body mass index (OR, 0.95; 95% CI, 0.93-0.97), or who were taking more medications (OR, 0.93; 95% CI, 0.88-0.98) had lower odds of an improved PCS.

Conclusions and Relevance

This cohort study of women in midlife suggests that approximately 15% of women experienced clinically important improvements in health and function over an 11-year period. Several potentially modifiable factors associated with improvements may inform women of variables to target for future interventions.

Differences in chronic pain prevalence between men and women at mid-life: a systematic review protocol

INTRODUCTION

Epidemiological literature shows differences in chronic pain (CP) prevalence in men and women. Women are more likely to develop CP at different points of the life course, such as adolescence and old age. Less is known about the prevalence of CP by sex and the difference in prevalence during mid-life, when changes may predispose to an earlier differentiation in CP distribution. The aim of this study is to describe the difference in prevalence of CP at mid-life (ages 40-60) in men and women in the general population.

METHODS AND ANALYSIS

This systematic review follows Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Appropriate studies will be identified in the following databases: MEDLINE, EMBASE, AMED and PsycINFO. Two reviewers will independently screen each title and abstract. Studies eligible for data extraction will report estimates of CP prevalence for each sex, and/or a measure of the difference in prevalence between sexes. The findings will be reported in a narrative synthesis following the Social Research Council Methods Programme guidelines. A random effects meta-analysis will be conducted where the reviewers can justify combining results.

ETHICS AND DISSEMINATION

This review will summarise the prevalence of CP in men and women at mid-life, based on existing evidence. It is expected that the results will identify gaps in knowledge and areas for further research. The review will be submitted for publication in topic specific journals and disseminated to professional networks. Individual patient data are not included, so ethical approval is not required.

The Measurement of Acculturation in Neuropsychological Evaluations of Hispanic/Latino Individuals across the Lifespan: A Scoping Review of the Literature

OBJECTIVE

Acculturation has been linked to health outcomes in Hispanics/Latinos (H/Ls). However, there is equivocal evidence of a relationship between acculturation and neuropsychological outcomes. Various factors limit the ability to subject the evidence to systematic/meta-analytic review. We sought to examine the current state of the literature in the context of H/Ls and neuropsychology and describe the various limitations of measuring acculturation across the lifespan.

METHOD

Applying a scoping review approach, we identified unique stand-alone (e.g., questionnaires) measures of acculturation. We focused on psychometric (e.g., internal consistency) and other characteristics (e.g., language, structure/format) and description of the validation samples (e.g., cultural background/country of origin).

RESULTS

A total of 40 unique acculturation measures were identified. Measures spanned various domains (e.g., language proficiency, food preference, music choice), and relied heavily on linguistic behavioral characteristics. Internal consistency varied from unacceptable to clinically acceptable ranges. Variable approaches to development and validation were reported. Validation samples varied from 22 to 2,048 respondents (median = 380), most of which represented a general adult population. Only eight measures were validated for use in pediatric populations; none were developed specifically for use with older adults.

CONCLUSIONS

Published measures are outdated, evidence highly variable psychometric and methodological weaknesses, and lack a lifespan perspective. Several themes in the types of items considered elemental to the acculturative process are revealed and findings are summarized via an "ABC" framework, categorizing items as antecedents, behaviors, and consequent acculturative changes, that lends itself to clinical and research settings.

Modifiable Lifestyle Activities Affect Cognition in Cognitively Healthy Middle-Aged Individuals at Risk for Late-Life Alzheimer's Disease

BACKGROUND

It is now acknowledged that Alzheimer's disease (AD) processes are present decades before the onset of clinical symptoms, but it remains unknown whether lifestyle factors can protect against these early AD processes in mid-life.

OBJECTIVE

We asked whether modifiable lifestyle activities impact cognition in middle-aged individuals who are cognitively healthy, but at risk for late life AD. Participants (40-59 years) completed cognitive and clinical assessments at baseline (N = 206) and two years follow-up (N = 174).

METHODS

Mid-life activities were measured with the Lifetime of Experiences Questionnaire. We assessed the impact of lifestyle activities, known risk factors for sporadic late-onset AD (Apolipoprotein E ɛ4 allele status, family history of dementia, and the Cardiovascular Risk Factors Aging and Dementia score), and their interactions on cognition.

RESULTS

More frequent engagement in physically, socially, and intellectually stimulating activities was associated with better cognition (verbal, spatial, and relational memory), at baseline and follow-up. Critically, more frequent engagement in these activities was associated with stronger cognition (verbal and visuospatial functions, and conjunctive short-term memory binding) in individuals with family history of dementia. Impaired visuospatial function is one of the earliest cognitive deficits in AD and has previously associated with increased AD risk in this cohort. Additionally, conjunctive memory functions have been found impaired in the pre-symptomatic stages of AD.

CONCLUSION

These findings suggest that modifiable lifestyle activities offset cognitive decrements due to AD risk in mid-life and support the targeting of modifiable lifestyle activities for the prevention of AD.

The Development of Generativity in Middle Adulthood and the Beginning of Late Adulthood: A Longitudinal Study from Age 42 to 61

Previous studies have yielded mixed results regarding the development of generativity during adulthood. Longitudinal data were utilized to investigate the average development of generativity between the ages of 42 and 61 as well as individual differences in terms of its development. The study used data from the Jyväskylä Longitudinal Study of Personality and Social Development (JYLS) (initial N = 369). The data consisted of 291 individuals whose generativity scores, measured using the Generativity Scale, were available at age 42, 50, or 61. Rasch analysis was utilized to form a generativity measure. The development of generativity between the measurements was investigated in women and men using Bland–Altman plots and the latent change score model. The results showed that, on average, generativity decreased from age 42 to 61 in women and men; however, there were individual differences in the extent and direction of the change with age. The level of generativity at age 42 predicted the change occurring between ages 42 and 50 and ages 50 and 61. Furthermore, the change between ages 42 and 50 predicted the change occurring between ages 50 and 61. The more positive the baseline value or the earlier occurring change, the more negative the subsequent change. To conclude, despite the mean-level generativity decreases during middle and late adulthood, there was variance across individuals of the same age, who were followed for nearly two decades. The study emphasizes the importance of investigating individual differences in the development of generativity in adulthood.

The Relationship between Personal and Contextual Factors and Participation Restriction in Mid-Life Caregivers

OBJECTIVES

Mid-life family caregivers (CGs) are at risk for participation restriction, which can worsen quality of care for care recipients (CR) and increase CG burden and poor health. We aimed to identify factors associated with participation restriction in mid-life CGs.

METHODS

This was a cross-sectional study of CGs aged 40-64 years (n = 1100) from the 2015 cohort of the National Study of Caregiving (NSOC)/National Health and Aging Trends Study (NHATS). Multivariate logistic regression was used to evaluate personal and caregiving attributes associated with restricted participation.

RESULTS

Individual items from the negative and Positive aspects of caregiving (PAC) scales were associated with participation restriction. Mid-life caregivers with "frequent changes to caregiving routine" and "no time for self" were more likely to report restricted participation and those feeling "closer to the CR" were less likely to report restricted participation.

DISCUSSION

Interventions to optimize caregiving routines and improve dyadic relationships could decrease participation restriction in mid-life CGs.

Self-rated mental health in the transition to adulthood predicts depressive symptoms in midlife

Self-rated mental health (SRMH), a single item asking individuals to evaluate their mental or emotional health, is included in some surveys as an indicator of risk for mental disorders and to monitor population health, yet little longitudinal research examines how well it predicts future outcomes. Following a life course perspective, the current longitudinal study of 502 Canadian high school seniors tracked into midlife examined to what extent SRMH at ages 20, 25, and 32 years predicted depressive symptoms at ages 43 and 50. Hierarchical linear regressions showed that lower SRMH at age 25 and at 32 years was a significant predictor of higher levels of depressive symptoms at ages 43 and 50, even when controlling for sex, participant education, marital/cohabitation status, self-rated physical health, and baseline depressive symptoms. The results provide evidence that SRMH assessed during the transition to adulthood may be useful as a broad and powerful measure of risk for mental health problems decades into the future.

Talking really does matter: Lay perspectives from older people on talking about suicide in later life

Background

The cumulative body of research on suicidality in later life describes its unique and complex features in older people when compared with that in other population groups. Yet significant gaps exist in how research informs the further development of suitable interventions. The perspectives of older people are also limited in research findings.

Aims

Therefore, this exploratory study aimed to (1) identify potential barriers and enablers in discussing suicidal thoughts and their expression in later life from the perspectives of lay older people and (2) explore where opportunities might occur in approach, place, relationships, and language with older people to discuss suicidal thoughts and their expression.

Method

We conducted in-depth qualitative individual interviews with 15 people aged 70-89 years. This method helped explore older peoples' own lay perspectives on suicidal thoughts in later life and how these are expressed, and their understanding of where and how people might seek support.

Results

A total of three themes were generated from the dataset: (1) intergenerational and socio-cultural differences in suicide expression, (2) the normalization of suicidal thoughts in later life, and (3) the importance and difficulties of everyday discussion and opportunities to express suicidal thoughts.

Conclusion

Suicidal thoughts and their expression appear commonly and are normalized in later life yet remain taboo and hidden. The participants revealed how such thoughts and behaviors are typically expressed through colloquial or "off-hand" remarks and comments and the importance of authentic listening. The findings highlight the importance of more informal discussions around these topics and how care professionals, practitioners, and providers might frame opportunities for dialogue with people who may want to access support. Further engagement with community-informed participatory research methods in which older people provide their own perspectives and experiences is important in addressing these gaps. There is a need for co-designing in developing screening, assessment, and signposting outside of clinical settings that can be used in everyday caring relationships with people in later life.

Within-person changes in religiosity, control beliefs, and subjective well-being across middle and late adulthood

Given the well-established link between control beliefs and well-being, researchers have turned their attention to characterizing mechanisms that help foster this relationship across the second half of life. Cross-sectional, empirical work has identified a mediating relationship among religiosity and spirituality (R/S), control beliefs, and subjective well-being, such that individuals with higher R/S show higher subjective well-being that is mediated by between-person differences in perceived control. Empirical tests of between-person differences, however, may not represent within-person associations. As such, the present study utilized longitudinal data from the Notre Dame Study of Health & Well-being (NDHWB; N = 1,017) to examine concurrent, within-person associations among three R/S dimensions (i.e., religious coping, religious practices, and spirituality), control beliefs, and subjective well-being. Results from our Bayesian multilevel mediation analyses showed significant within-person associations among these constructs, suggesting potential bidirectionality and circularity in these processes. Cross-sectional age differences and time significantly moderated these associations. In terms of age differences, younger, compared to older, individuals showed stronger positive associations among religious coping and spirituality, control beliefs, and subjective well-being and more negative associations among religious practices, control beliefs, and subjective well-being. Contrarily, the effect of time implied that the relationships among religious coping and spirituality, control beliefs, and subjective well-being became more positive across time. Given this disjunction and that the moderating effect of cross-sectional age by time was not significant, cross-sectional age differences in these relationships likely reflect generational differences in the associations among R/S, control beliefs, and subjective well-being.

Preparedness for healthy ageing and polysubstance use in long-term cannabis users: a population-representative longitudinal study

BACKGROUND

Cannabis is often characterised as a young person's drug. However, people who began consuming cannabis in the 1970s and 1980s are no longer young and some have consumed it for many years. This study tested the preregistered hypothesis that long-term cannabis users show accelerated biological ageing in midlife and poorer health preparedness, financial preparedness, and social preparedness for old age.

METHODS

In this longitudinal study, participants comprised a population-representative cohort of 1037 individuals born in Dunedin, New Zealand, between April, 1972, and March, 1973, and followed to age 45 years. Cannabis, tobacco, and alcohol use and dependence were assessed at ages 18 years, 21 years, 26 years, 32 years, 38 years, and 45 years. Biological ageing and health, financial, and social preparedness for old age were assessed at age 45 years. Long-term cannabis users were compared using independent samples t tests with five groups: lifelong cannabis non-users, long-term tobacco users, long-term alcohol users, midlife recreational cannabis users, and cannabis quitters. In addition, regression analyses tested dose-response associations for continuously measured persistence of cannabis dependence from age 18 years to 45 years, with associations adjusted for sex, childhood socioeconomic status, childhood IQ, low childhood self-control, family substance dependence history, and persistence of alcohol, tobacco, and other illicit drug dependence.

FINDINGS

Of 997 cohort members still alive at age 45 years, 938 (94%) were assessed at age 45 years. Long-term cannabis users showed statistically significant accelerated biological ageing and were less equipped to manage a range of later-life health, financial, and social demands than non-users. Standardised mean differences between long-term cannabis users and non-users were large: 0·70 (95% CI 0·46 to 0·94; p<0·0001) for biological ageing, -0·72 (-0·96 to -0·49, p<0·0001) for health preparedness, -1·08 (-1·31 to -0·85; p<0·0001) for financial preparedness, and -0·59 (-0·84 to -0·34, p<0·0001) for social preparedness. Long-term cannabis users did not fare better than long-term tobacco or alcohol users. Tests of dose-response associations suggested that cannabis associations could not be explained by the socioeconomic origins, childhood IQ, childhood self-control, and family substance-dependence history of long-term cannabis users. Statistical adjustment for long-term tobacco, alcohol, and other illicit drug dependence suggested that long-term cannabis users' tendency toward polysubstance dependence accounted for their accelerated biological ageing and poor financial and health preparedness, although not for their poor social preparedness (β -0·10, 95% CI -0·18 to -0·02; p=0·017).

INTERPRETATION

Long-term cannabis users are underprepared for the demands of old age. Although long-term cannabis use appears detrimental, the greatest challenge to healthy ageing is not use of any specific substance, but rather the long-term polysubstance use that characterises many long-term cannabis users. Substance-use interventions should include practical strategies for improving health and building financial and social capital for healthy longevity.

Higher education and health at midlife: Evaluating the role of college quality

Using the longitudinal data from the National Longitudinal Survey of Youth-1979 linked with external data on college characteristics (N = 7056), this study illustrates an independent stratifying role of college quality in shaping health. College quality has significant and positive influences on physical health, and this positive association tends to strengthen across 40 and 50. By contrast, attending higher-quality colleges is not associated with mental health at either age 40 or age 50. Decompositions were conducted to assess the extent to which early life and demographic characteristics, employment and economic conditions, health behaviors, and family relationships account for observed patterns. Our study highlights the necessity for future research on education and health to incorporate characteristics of schools attended; reveals variation in the college quality-health nexus by specific health outcomes; and provides new insights into understanding health inequalities across the life course.

Mobile learning: research context, methodologies and future works towards middle-aged adults - a systematic literature review

Over the past several years, mobile learning concepts have changed the way people perceived on mobile devices and technology in the learning environment. In earlier days, mobile devices were used mainly for communication purposes. Later, with many new advanced features of mobile devices, they have opened the opportunity for individuals to use them as mediated technology in learning. The traditional way of teaching and learning has shifted into a new learning dimension, where an individual can execute learning and teaching everywhere and anytime. Mobile learning has encouraged lifelong learning, in which everyone can have the opportunity to use mobile learning applications to gain knowledge. However, many of the previous studies on mobile learning have focused on the young and older adults, and less intention on middle-aged adults. In this research, it is targeted for the middle-aged adults which are described as those who are between the ages of 40 to 60. Middle-aged adults typically lead very active lives while at the same time are also very engaged in self-development programs aimed at enhancing their spiritual, emotional, and physical well-being. In this paper, we investigate the methodology used by researchers based on the research context namely, acceptance, adoption, effectiveness, impact, intention of use, readiness, and usability of mobile learning. The research context was coded to the identified methodologies found in the literature. This will help one to understand how mobile learning can be effectively implemented for middle-aged adults in future work. A systematic review was performed using EBSCO Discovery Service, Science Direct, Google Scholar, Scopus, IEEE and ACM databases to identify articles related to mobile learning adoption. A total of 65 journal articles were selected from the years 2016 to 2021 based on Kitchenham systematic review methodology. The result shows there is a need to strengthen research in the field of mobile learning with middle-aged adults.

Harnessing progress: Gender, sexuality, and positive self-perceptions of aging in midlife

Drawing on interviews, this article analyzes how lesbians, gay men, straight women, and straight men construct positive views of aging during midlife, a life course period when negative perceptions of aging are salient. Interviewees engaged in harnessing progress-a process of crafting personal aging narratives that emphasize growth and improvement-which helped them to feel positively about their own aging. All interviewees shared these progress narratives, but reports differed across gender and sexuality groups. Men's narratives focused on the wisdom they gained and how that made them more relevant to older and younger generations. Regarding the latter, straight men viewed their children as beneficiaries of their progress and gay men viewed younger LGBTQ people as beneficiaries. Women's progress narratives focused on self-improvement. Whereas straight women described becoming more self-reliant with age, lesbians described learning to stand up for themselves. Overall, findings reveal how gender and sexual identities-and the lifelong benefits and burdens that accompany those identities-influence how people create positive perceptions of aging.
