"Lives and times": The case for qualitative longitudinal research in anatomical sciences education.

Qualitative longitudinal research (QLR) focuses on changes in perceptions, interpretations, or practices through time. Despite longstanding traditions in social science, QLR has only recently appeared in anatomical sciences education (ASE). While some existing methodology papers guide researchers, they take a narrow view of QLR and lack specificity for ASE. This discursive article aims to (1) describe what QLR is and its benefits, its philosophies, methodologies and methods, considerations, and quality indicators, and (2) critically discuss examples of QLR in ASE. Underpinned by relativist ontology and subjectivist epistemology, time can be understood as fluid/subjective or fixed/objective. QLR is a flexible, creative, and exploratory methodology, often associated with other methodologies. Sampling is typically purposive, with repeated and recursive data collection methods, and complex three-strand analyses (themes, cases, and time), enabling cross-sectional and longitudinal analyses. QLR involves ethical, relationship, analytical, dissemination, and funding considerations. Key quality indicators relate to qualitative research as well as temporal aspects. Most of the nine ASE papers reviewed explored changes in anatomy learners, but few labeled their methodology as QLR. Just under half described their sampling as purposive, most employed pre-planned and standardized repeated interviews, analyzed their data cross-sectionally, and utilized qualitative data analysis software. Most cited the confirmability and transferability of their studies, but few cited credibility and dependability elements. Study timeframes and tempos were generally clear, but details of longitudinal retention/attrition were often lacking, and longitudinal data analysis was not often conducted. We therefore provide recommendations for the conduct of QLR in ASE.

Role of intergenerational connections in cognitive aging: Evidence from a Chinese longitudinal study.

Objective: To explore the impact of intergenerational connections on cognitive function in middle-aged and older adults (45-60 years and over 60 years, respectively) and analyze the urban-rural and sex differences in the effects of intergenerational connections on cognitive function. Method: Based on China Health and Retirement Longitudinal Study data (CHARLS), this study conducted ID matching for four waves of data from 2011, 2013, 2015, and 2018. Cognitive function was measured via Telephone Interview for Cognitive Status-modified (TICS-m), word recall, and imitation drawing. Using a combination of cross-sectional and longitudinal research, we constructed the cross-lagged panel model (CLPM) with a sample of 1,480 participants to explore the relationship between intergenerational connections and cognitive function. Results: This study examines the impact of intergenerational connections on cognitive function in middle-aged (45-60 years) and older adults (over 60 years) using data from the CHARLS. It identifies urban-rural and sex differences, with notable effects among rural female participants. The frequency of meeting with one child negatively predicts cognitive function (ß = -0.040, p = 0.041), and the frequency of communication with one child positively predicts cognitive function (ß = 0.102, 0.068, 0.041, p < 0.001, p = 0.001, 0.045). Meanwhile, intergenerational connections with multiple children positively predicts cognitive function (ß = 0.044, p = 0.031), (ß = 0.128, 0.084, and 0.056, p < 0.001, 0.001, p = 0.008). There are urban-rural and sex differences in the effects of intergenerational connections on cognitive function; additionally, the effects of intergenerational connections on cognitive function are significant in rural female middle-aged and older adults. Discussion: This study proposes the theory of skewed intergenerational support, which suggests that as middle-aged and older adults age, the responsibility for intergenerational support is skewed toward one child. This leads to conflicts between middle-aged and older parents and the child, which further affects cognitive function. In addition, this study put forward the boat-carrying theory of intergenerational relations and "to hold a bowl of water level" is the art of dealing with intergenerational relationships.

Emphasizing the need for longitudinal research and cultural adaptation in mindfulness-based interventions for cancer patients.

This letter to the editor emphasizes the importance of conducting longitudinal research on mindfulness-based interventions (MBIs) for cancer patients to better understand their long-term impact on mental health and quality of life. It also calls for research focused on cultural and contextual adaptations of MBIs to ensure their relevance and effectiveness in diverse populations. By prioritizing these areas, researchers can optimize MBIs, making them more sustainable and applicable across different cultural and geographical contexts, ultimately improving the overall well-being of cancer patients worldwide.

Understanding the motivational mechanisms for smoking and vaping among dual users and exclusive smokers.

BACKGROUND: Understanding the motivational processes that influence e-cigarette use in a laboratory setting may help elucidate mechanisms that support long-term ecigarette use, which could have significant clinical and public health consequences. METHODS: Secondary analyses were conducted on data from exclusive smokers (N=47) and dual users (N=88) who underwent a laboratory ad lib use session. Participants were given 10minutes to smoke (exclusive smokers) or vape (dual users) as much as they wanted. Withdrawal was assessed pre- and post-use. Smoking and vaping behavior was coded from session videos. Person-level predictors included cigarette/ecigarette craving-relief expectancies, demographics, and cigarette/e-cigarette use and dependence. Smoking and vaping status was assessed at Year 1 using self-reported 30-day point prevalence. Data were analyzed using general linear models and logistic regressions. RESULTS: Both groups reported reductions in withdrawal after product use, including cigarette craving. Baseline e-cigarette craving-relief expectancies, pre-session ecigarette craving, heaviness of e-cigarette use, and relative e-cigarette dependence were significant univariate predictors of continued vaping in dual users at Year 1 (ORs>1.04, ps<.05). Dual users and exclusive smokers did not differ on use behavior (i.e., average number of puffs, ps>.16). CONCLUSIONS: E-cigarette use alleviated withdrawal, including cigarette and e-cigarette craving, in dual users. Laboratory use behavior did not differ between dual users using e-cigarettes and exclusive smokers using cigarettes. Greater e-cigarette craving-relief expectancies, e-cigarette craving, heaviness of e-cigarette use, and morning product use pattern ('relative dependence') may reflect mechanisms that sustain e-cigarette use.

Assessment of Long-Term Pulmonary Function and Quality of Life in Patients with Chronic Obstructive Pulmonary Disease (COPD).

Background: Chronic obstructive pulmonary disease (COPD) is a prevalent respiratory condition portrayed by persistent airflow limitation and correlated symptoms. Despite advances in treatment, COPD remains a significant global health burden, necessitating ongoing research to understand its long-standing impact on pulmonary function and quality of life (QoL). Methods: This longitudinal research enrolled 200 COPD and followed them over a 5-year period. Baseline assessments included spirometry to measure forced expiratory volume in one second (FEV1) and forced vital capacity (FVC), along with standardized questionnaires assessing QoL. Follow-up assessments were conducted annually, and statistical analysis was performed to examine changes in pulmonary function and QoL over time. Results: Significant declines in FEV1 and FVC were observed at each follow-up time point compared to the baseline, indicating progressive deterioration in lung function. QoL scores, as assessed by the St. George's Respiratory Questionnaire and the COPD Assessment Test, also worsened progressively over the research period. Conclusion: Current conclusions underscore the progressive nature of COPD, highlighting the importance of proactive management strategies aimed at preserving lung function and improving QoL. Early intervention and ongoing monitoring are essential in optimizing outcomes for COPD subjects and reducing the disease burden on individuals and healthcare systems.

Exploring the reciprocal relationships between body image flexibility and body fat and muscularity dissatisfaction: An 18-month longitudinal study in Chinese adolescents.

Body image flexibility has shown robust negative associations with body dissatisfaction. However, research in this area is confined to cross-sectional studies on adults in Western cultural contexts. Responding to these gaps and the unique cultural nuances and increasing prevalence estimates of body dissatisfaction in China, we examined the bi-directional nature of body image flexibility and body fat and muscularity dissatisfaction in Chinese adolescent boys and girls (N = 1381, 57.3 % girls) at two points over 18 months (Wave [W] 1=baseline, W2=18 months later). We also explored sex differences in longitudinal models. In boys, higher W1 body image flexibility was associated with lower W2 body fat dissatisfaction, and higher W1 body fat dissatisfaction was associated with lower W2 body image flexibility. Null prospective associations between body image flexibility and muscularity dissatisfaction were identified in boys. In girls, higher W1 body fat and muscularity body dissatisfaction were associated with lower W2 body image flexibility. Higher W1 body image flexibility was associated with lower W2 body fat and muscularity dissatisfaction in girls. We found no significant sex differences in the models. Findings advance a multicultural understanding of the temporal and bi-directional links between body image flexibility and body fat and muscularity dissatisfaction in Chinese adolescents.

Navigating household food insecurity and environmental sustainability on a low income: An exploration of Sheffield mothers.

In 2023, 25% of adults in England, Wales and Northern Ireland experienced food insecurity. The concentration of food insecurity in both socioeconomically disadvantaged groups and households containing children raises concerns about its uneven nutritional and health impacts across different groups. In parallel with rising food insecurity over the past decade, concerns about the environmental consequences of human diets are intensifying, where urgent changes are needed to people's diets to avoid irreversible environmental damage. It is generally assumed that cost has a significant impact on people's ability to adopt more environmentally sustainable food practices. This UK Research Council-funded project seeks to gain insights into the ways in which low-income mothers (are able to) engage with environmentally sustainable food practices. RQ1 will examine the day-to-day food practices that mothers undertake for their families to offer insights into everyday food insecurity and the relevance of environmentally sustainable food practices. RQ2 will explore biographical experiences to highlight how mothers' life histories influence their familial food practices, including their current household food security and engagement with environmentally sustainable food practices. Finally, RQ3 will explore mothers' upcoming prospects of food insecurity and environmentally sustainable food practices. These research questions will be explored through a qualitative longitudinal, feminist study of 15 low-income mothers in Sheffield, UK, combining in-depth interviews with ethnographic elements. Gaining improved knowledge of mothers' food practices on a low income will be valuable to influence realistic, effective and meaningful philosophies, policies and practical action that prioritises equity, good nutrition and environmentally sustainable food practices.

Exploring preparedness transitions in medicine and pharmacy: a qualitative longitudinal study to inform multiprofessional learning opportunities.

Despite extensive preparedness literature, existing studies fail to adequately explore healthcare graduates' feelings of preparedness longitudinally across new graduate transition journeys, nor do they compare different healthcare professions to ascertain what opportunities exist for multiprofessional transition interventions. Therefore, this Australian study, underpinned by temporal theory, explores the preparedness transitions of medicine and pharmacy graduates. Our 6-month qualitative longitudinal study involved 12 medicine and 7 pharmacy learners after purposive sampling. They participated in an entrance interview before starting internship, longitudinal audio-diaries during their first three months of internship, and an exit interview. Framework analysis explored patterns in the data cross-sectionally and longitudinally for the whole cohort (thinking over time), with pen portraits illustrating individuals' journeys (thinking through time). Preparedness and unpreparedness narratives involved practical skills and tasks, interpersonal skills, knowledge, and professional practice for medicine and pharmacy. However, narratives for practical skills and tasks, and professional practice were dominant amongst medicine graduates, while narratives for interpersonal skills and knowledge were dominant amongst pharmacy graduates. We found numerous cohort changes in feelings of preparedness over time, but the illustrative pen portraits demonstrated the complexities and nuances through time, including feelings of preparedness before internship becoming unpreparedness during internship (e.g., cannulas), improving preparedness through time (e.g., cover shifts), and persistent feelings of unpreparedness (e.g., patient interactions). While our cross-sectional findings are reasonably consistent with existing research, our comparative and longitudinal findings are novel. We recommend that educators build learners' preparedness through uniprofessional transition interventions involving practical skills and tasks, and professional practice in medicine, and interpersonal skills and knowledge in pharmacy. More importantly, we recommend multiprofessional transition interventions for medicine and pharmacy learners before internship focusing on knowledge, and during internship focusing on practical skills and tasks.

Measuring Continuous Affect in Daily Life With Intensity Profile Drawings.

We examined continuous affect drawings as innovative measure of affective experiences over time. Intensive longitudinal data often rely on discrete assessments, containing "blind spots" between measurements. With continuous affect drawings participants visually depict their affect fluctuations between assessments. In an experience sampling study, participants (N = 115) rated their momentary positive and negative affect 6 times daily. From the second daily rating on, they additionally drew their positive and negative affect changes and reported affective events between assessments. They received one measurement burst between assessments daily. The strength of the approach is a substantial amount of informational gain (average 7%) over linearly interpolated points between assessments. The additional information was subsequently categorized into positive and negative affect peaks and valleys, each occurring once a day per person on average. The probability of detecting peaks and valleys increased with reported events. The drawings correlated positively with momentary affect scores from the burst. Yet, the drawing predicted the bursts less well suggesting that the momentary ratings may yield different information than the drawings. Although the timing of retrospective drawings is less precise than individual momentary assessments, this method provides a comprehensive understanding of affective experiences between assessments, offering a unique perspective on affect dynamics.

Coping style as a risk factor for future alcohol use disorder: A 16-year longitudinal study in a Canadian military sample.

BACKGROUND: Coping strategies used in response to stress have the potential to influence the development of mental health disorders, including alcohol use disorders. The current study investigated whether coping strategies placed an individual at greater likelihood for developing a future alcohol use disorder. METHODS: This study used data from the Canadian Armed Forces Members and Veterans Mental Health Follow-up Survey; a nationally representative 16-year follow-up survey, with initial data collected in the 2002 Canadian Community Health Survey - Canadian Forces Supplement. The total sample from the two datasets included 2941 individuals who were Regular Force members in 2002. Coping styles included problem-focused, avoidant, and self-medication. Adjusted logistic regression analyses examined relationships between coping style (in 2002) and alcohol use disorders (developed between 2002 and 2018). RESULTS: Self-medication coping in 2002 was associated with any alcohol disorder since last interview (i.e., 2002-2018) (AOR 1.26; 95 % CI, 1.02-1.57) and during the past year (adjusted odds ratios [AOR 1.26; 95 % CI, 1.08-1.47]), as well as past-year binge drinking (AOR 1.19; 95 % CI, 1.09-1.29). Problem-focused coping was protective against past-year alcohol abuse (AOR 0.84; 95 % CI, 0.71-1.00) and any alcohol use disorder (AOR 0.87; 95 % CI 0.76-1.00). CONCLUSION: Coping styles were strongly associated with future alcohol use disorders. Notably, results show the risk extended over a 16-year period. Findings suggest the use of self-medicating coping strategies places an individual at increased risk of developing alcohol use disorders, while problem-focused coping may decrease future risk of alcohol use disorders.

Trajectories of quality of life among disaster victims: A national longitudinal study.

AIM: This study categorized quality-of-life trajectories among disaster victims in South Korea and identified the characteristics and predictors of each trajectory. BACKGROUND: Disaster victims experience tremendous physical and mental distress, which has a long-term impact on their quality of life. METHODS: We conducted a cross-sectional study using data obtained from the fourth Long-term Survey on the Change of Life of Disaster Victims conducted from 2017 to 2019. The study included 257 participants who experienced a typhoon, earthquake, or fire and completed the three-year follow-up. Latent transition analysis was used to identify the potential class of quality-of-life trajectories among disaster victims. Independent t tests, χ2 tests, and logistic regression were used to identify the predictors of quality-of-life trajectories. RESULTS: Two latent quality-of-life classes were identified: persistent low-level and persistent high-level. Factors associated with the persistent high-level trajectory included higher education level, no injury/disease from the disaster, better subjective health status, higher social support, and lower social maladjustment. DISCUSSION: Quality of life early after a disaster is maintained throughout subsequent years; early and active support following disasters is essential to promote its rapid improvement. CONCLUSION: Targeted educational programs in disaster-prone areas are recommended to bolster resilience among individuals with lower education. Moreover, governmental and institutional efforts are needed to support victims who lack resources for disaster recovery. IMPLICATIONS FOR NURSING AND HEALTH POLICY: There is a need to establish community-based social support systems and enhance nurses' disaster response capabilities to support vulnerable groups, with such interventions tailored to reflect disaster-affected victims' unique characteristics and needs, along with ongoing research and evaluation for continuous improvements to nursing practice and disaster response.

Associations of early changes in lung ultrasound aeration scores and mortality in invasively ventilated patients: a post hoc analysis.

BACKGROUND: Lung ultrasound (LUS) in an emerging technique used in the intensive care unit (ICU). The derivative LUS aeration score has been shown to have associations with mortality in invasively ventilated patients. This study assessed the predictive value of baseline and early changes in LUS aeration scores in critically ill invasively ventilated patients with and without ARDS (Acute Respiratory Distress Syndrome) on 30- and 90-day mortality. METHODS: This is a post hoc analysis of a multicenter prospective observational cohort study, which included patients admitted to the ICU with an expected duration of ventilation for at least 24 h. We restricted participation to patients who underwent a 12-region LUS exam at baseline and had the primary endpoint (30-day mortality) available. Logistic regression was used to analyze the primary and secondary endpoints. The analysis was performed for the complete patient cohort and for predefined subgroups (ARDS and no ARDS). RESULTS: A total of 442 patients were included, of whom 245 had a second LUS exam. The baseline LUS aeration score was not associated with mortality (1.02 (95% CI: 0.99 - 1.06), p = 0.143). This finding was not different in patients with and in patients without ARDS. Early deterioration of the LUS score was associated with mortality (2.09 (95% CI: 1.01 - 4.3), p = 0.046) in patients without ARDS, but not in patients with ARDS or in the complete patient cohort. CONCLUSION: In this cohort of critically ill invasively ventilated patients, the baseline LUS aeration score was not associated with 30- and 90-day mortality. An early change in the LUS aeration score was associated with mortality, but only in patients without ARDS. TRIAL REGISTRATION: ClinicalTrials.gov, ID NCT04482621.

Tax increases as an incentive to quit smoking: is thinking about quitting due to a tobacco tax increase associated with post-tax increase smoking cessation?

BACKGROUND: The cost of tobacco is one of the most reported reasons to quit smoking. The Netherlands increased tobacco taxes twice in the span of nine months: a €1 increase per pack in April 2020, and a €0.12 increase per pack in January 2021. This study examines to what extent people report to think about quitting due to the upcoming tax increase(s), as well as how it relates to their age, income or educational level. Additionally, we examined whether thinking about quitting was associated with quit intention and quit behaviour, and whether these associations were different for the two tax increases. METHODS: Longitudinal data from the International Tobacco Control (ITC) Netherlands Surveys, Cohort 2 were used (N = 5919 observations; wave 1 (February - March 2020): n = 2051; wave 2 (September - November 2020): n = 1919; wave 3 (June - July 2021): n = 1949). Generalised Estimating Equation (GEE) regressions were fit to test the associations between thinking about quitting due to the tax increase and post-tax increases in quit intention, serious quit attempts, and quitting smoking (≤ 1 cigarette a month), as well as sociodemographic variables. RESULTS: Circa half of the people who smoke reported thinking about quitting smoking due to the upcoming tax increase (Wave 1 = 51.3% (n = 1052); Wave 2 = 47.3% (n = 849)). Individuals who reported thinking about quitting smoking due to upcoming tax increase(s) were more likely to have increased their quit intention (aOR: 2.00, p ≤ .001) or have carried out a serious quit attempt (aOR:1.48, p ≤ .001) post-tax increase. More people attempted to quit smoking between wave 2 and 3 (post 2021 increase) than between wave 1 and 2 (post 2020 increase). We did not find an interaction effect between wave and thinking about quitting for quit intention, quit attempts, and quitting smoking. CONCLUSIONS: Tax increases stimulate people to think about quitting. Thinking about quitting due to an upcoming tax increase was associated with more positive quit intention and serious quit attempts.

Does e-cigarette use predict short-term smoking cessation behaviors among adults who smoke in Mexico? A longitudinal study.

INTRODUCTION: This study assessed quit attempts among adults who use cigarettes either exclusively or with e-cigarettes in Mexico, where non-daily smoking predominates. METHODS: An open cohort of Mexican adults who smoke was surveyed every four months from November 2018 to March 2021. Participants followed to the next survey were analyzed (n = 2220 individuals, 4560 observations). Multinomial logistic models regressed smoking quit attempts reported at the followup survey (ref = no attempt; tried to quit; sustained attempt of ≥30 days) on e-cigarette use frequency (none = ref; 1-2 days/week; ≥3 days/week), adjusting for sociodemographics and smoking-related variables. Additional models subdivided e-cigarette users by intentions to quit smoking in the next six months (i.e., yes/no), use of nicotine (i.e., yes/no), and vaping device used (i.e., open/closed). RESULTS: At 4-month follow-up, 32.7 % had tried to quit, and 2.9 % had quit for 30 days or more. Compared to those who smoke exclusively, occasional, and frequent e-cigarette users were more likely to try to quit (Adjusted Relative Risk Ratio or ARRR = 1.26 and 1.66, respectively) but no more likely to sustain their quit attempt. Among those who intended to quit smoking, e-cigarette users were no more likely to either try or sustain quit attempts. Furthermore, use of e-cigarettes with nicotine (59.6 %) was unassociated with cessation except that those who frequently used e-cigarettes with nicotine were more likely to try to quit than those who smoke exclusively (ARRR = 1.88). Device type used was not differentially associated with outcomes. CONCLUSIONS: Mexicans who smoke and use e-cigarettes appear more likely than those who smoke exclusively to try to quit but not to sustain abstinence.

Sleeping more than 8 h: a silent factor contributing to decreased muscle mass in Chinese community-dwelling older adults.

BACKGROUND: Muscle mass loss is an age-related process that can be exacerbated by lifestyle, environmental and other factors, but can be mitigated by good sleep. The objective of this study was to investigate the correlation between varying time lags of sleep duration and the decline in muscle mass among individuals aged 60 years or older by using real-world health monitoring data obtained from wearable devices and smart home health monitoring devices. METHODS: This study included 86,037 observations from 2,869 participants in the Mobile Support System database. Missing data were supplemented by multiple imputation. The investigation utilized generalized estimating equations and restricted cubic spline curve to examine the relationship between sleep duration and low muscle mass. Various lag structures, including 0, 1, 2, 0-1, 0-2, and 1-2 months, were fitted, and the interaction effect of observation time with sleep duration was estimated for each lag structure. Additionally, subgroup analyses were conducted. The models were adjusted for various covariates, including gender, age, body mass index, footsteps, smoking status, drinking status, marital status, number of chronic diseases, number of medications, diabetes mellitus, hyperlipidemia, coronary artery disease, respiratory disease, and musculoskeletal disease and an interaction term between time and sleep duration. RESULTS: The results of the generalized estimating equation showed a significant correlation (p < 0.001) between sleep duration of 8 h or more and low muscle mass in older adults, using 6-7 h of sleep as a reference. This effect was seen over time and prolonged sleep accumulated over multiple months had a greater effect on muscle mass loss than a single month. The effect of long sleep duration on muscle mass loss was significantly greater in females than in males and greater in the over-75 than in the under-75 age group. Restricted cubic spline plots showed a non-linear relationship between sleep duration and low muscle mass (p < 0.001). CONCLUSIONS: This study found an association between sustained nighttime sleep of more than eight hours and decreased muscle mass in older adults, especially older women.

Clarifying the Links between Perceived Stress and Depressiveness: a Longitudinal Study of COVID-19's Effects on Adolescents in Germany.

Young people are navigating an increasingly uncertain and unstable social and economic environment, further complicated by COVID-19. Individual resources and vulnerabilities, such as mental health and sensitivity to stress, play a significant role in how well youth adapt to the career paths and living conditions altered by the pandemic, a dynamic that is not yet well understood. This study examined the role of COVID-19 on the intertwined relation between perceived stress and depressiveness (negative and positive affect) in adolescents, focusing on gender differences. Longitudinal data from 673 German adolescents (Mage = 16.8 years, SDage = 0.91; female = 59%) were collected in three waves, before (T1) and during the pandemic (T2, T3). Using Latent Change Score models, the bidirectional relation between perceived stress and depressiveness was analyzed, considering gender as a moderator. The results showed that adolescents who found their situation stressful were at risk of developing depressiveness at the outbreak of the pandemic and throughout its progression. As the pandemic progressed, an increase in positive affect was linked to heightened perceived stress. Gender-specific differences were particularly evident in the levels of perceived stress and depressiveness, with women being more vulnerable. This study highlights how vulnerabilities in stress perception affect adolescents' mental health, with gender-specific differences underscoring the need for tailored mental health measures.

Using non-invasive behavioral and physiological data to measure biological age in wild baboons.

Biological aging is near-ubiquitous in the animal kingdom, but its timing and pace vary between individuals and over lifespans. Prospective, individual-based studies of wild animals-especially non-human primates-help identify the social and environmental drivers of this variation by indicating the conditions and exposure windows that affect aging processes. However, measuring individual biological age in wild primates is challenging because several of the most promising methods require invasive sampling. Here, we leverage observational data on behavior and physiology, collected non-invasively from 319 wild female baboons across 2402 female-years of study, to develop a composite predictor of age: the non-invasive physiology and behavior (NPB) clock. We found that age predictions from the NPB clock explained 51% of the variation in females' known ages. Further, deviations from the clock's age predictions predicted female survival: females predicted to be older than their known ages had higher adult mortality. Finally, females who experienced harsh early-life conditions were predicted to be about 6 months older than those who grew up in more benign conditions. While the relationship between early adversity and NPB age is noisy, this estimate translates to a predicted 2-3 year reduction in mean adult lifespan in our model. A constraint of our clock is that it is tailored to data collection approaches implemented in our study population. However, many of the clock's components have analogs in other populations, suggesting that non-invasive data can provide broadly applicable insight into heterogeneity in biological age in natural populations.

Keeping Us Young? Grandchild Caregiving and Older Adults' Cognitive Functioning.

Objective: This study investigates longitudinal associations between providing care to grandchildren and cognitive functioning. It also examines heterogeneity in these relationships. Background: Grandchild caregiving may support older adults' cognitive functioning by providing social engagement and emotional meaning. However, studies caution that time- intensive or custodial grandchild caregiving can take a toll on grandparents. The cognitive health implications of grandchild caregiving may thus depend on contexts including time spent providing care and living arrangements. They may also vary across sociodemographic groups and have greater effects on older adults who are more vulnerable to cognitive decline. Method: Data came from the 1998-2016 waves of the Health and Retirement Study (HRS) and represented over 11,000 U.S. adults age 50+. Using linear growth curve and dynamic panel models, the analysis explored relationships between level of grandchild care and cognitive functioning over time and across sociodemographic, family, work and health characteristics. Results: Those providing 100-199, 200-499 or 500+ hours of care to grandchildren had better cognitive functioning than non-caregivers regardless of whether they lived with grandchildren. Positive links between grandchild caregiving and cognition were stronger for lower income, non-working, and unpartnered adults and grew with age and functional limitations. Conclusion: These findings suggest that providing care to minor grandchildren may help support cognitive functioning as adults age. They also support the hypothesis that more vulnerable or isolated groups of older adults may benefit the most from grandchild caregiving.

Positive school climate and strong school identification as protective factors of adolescent mental health and learning engagement: A longitudinal investigation before and during COVID-19.

The COVID-19 pandemic resulted in significant disruptions for children and youth around the world, especially given school closures and shifts in teaching modes (on-line and hybrid). However, the impact of these disruptions remains unclear given data limitations such as a reliance on cross-sectional and/or short-interval surveys as well as a lack of broad indicators of key outcomes of interest. The current research employs a quasi-experimental design by using an Australian four-year longitudinal survey with student responses from Grade 7 to 10 (aged 12-15 years old) (N = 8,735 from 20 schools) in one education jurisdiction. Responses are available pre-pandemic (2018 and 2019) and during the pandemic (2020 and 2021). Importantly the survey included measures of well-being, mental health and learning engagement as well as potential known school-environment factors that could buffer against adversity: school climate and school identification. The findings were generally in line with key hypotheses; 1) during COVID-19 students' learning engagement and well-being significantly declined and 2) students with more positive school climate or stronger school identification pre-COVID-19 fared better through the disruption of the pandemic. However, these same students suffered from a steeper decline in well-being and engagement which may be explained through the impact of losing meaningful social or group connections. This decline was evident after controlling for gender, academic grade (as a proxy of age), parental education, and socioeconomic status. It is concluded that investing in the social environment of schools is important in crisis preparedness and can facilitate better crisis response among youth.

Counternarratives that illuminate faculty agency: A five-year longitudinal qualitative study of physician educators in academic medicine.

PURPOSE: Physician educators are often expected to direct educational programs and assume roles that conform to field norms for career advancement but that may not afford meaningful work for educators. The purpose of this study was to describe and analyse the perspectives and actions taken by physician educators in response to tension between feeling compelled to direct an educational program and doing educationally meaningful work. METHODS AND MATERIALS: We used data from a longitudinal study and focused on three participants who, over the course of the five-year study, offered significant insights into how physician educators act in ways that run counter to expectations for career advancement. Our narrative analysis entailed organizing data from interview transcripts into time-ordered displays, weaving data into counternarratives that were edited by participants, and using the theory of faculty agency (and its key constructs, strategic perspectives and strategic action) to thread the stories together. RESULTS: In each counternarrative, the participant deliberated their sense of being a physician educator (strategic perspectives) and when expectations became untenable, they did what they needed to do to engage in meaningful work (strategic action) rather than comply with expectations for career advancement in academic medicine. For one participant, faculty agency meant leaving academic medicine; for another, it meant reducing clinical time so that unpaid time could be devoted to education; and for another, it meant opting not do direct a reputable education program. CONCLUSIONS: Faculty agency is a useful theoretical lens for conceptualizing how physician educators navigate their careers in academic medicine. Counternarratives that illuminate faculty agency offer stories that describe alternate career paths and portend a different future for physician educators.
