Feasibility of the Remembering Warmth and Safeness Intervention in older ADRD caregivers.

BACKGROUND: The number of older adults in the U.S. living with ADRD is projected to increase dramatically by 2060. As older adults increasingly assume informal caregiving responsibilities, community-based intervention to sustain caregiver well-being is a dementia research priority. OBJECTIVE: To evaluate the feasibility of the RWSI among older ADRD caregivers. The RWSI is informed by the Neurovisceral Integration Model, in which memories that engage safety signals cultivate feelings of safety and well-being. METHODS: A within-subjects pre/post-intervention design with older ADRD caregivers to evaluate feasibility (acceptability, demand, fidelity) and empirical promise (well-being). RESULTS: The feasibility of the RWSI, implemented with fidelity, was strongly endorsed, as participants attended each intervention session, after which reported experiencing feelings of warmth and safeness, and provided the highest possible acceptability ratings. Participant narratives provided corroboration. DISCUSSION: Findings support the feasibility of the RWSI in older ADRD caregivers, providing the basis for continued research.

Relations Between Cardiorespiratory Fitness and Cognition in Older Adults With Amnestic Mild Cognitive Impairment From the Aerobic Exercise and Cognitive Training (ACT) Trial: Sex Differences.

Objective: To examine the associations of cardiorespiratory fitness with executive function, episodic memory, and global cognition and sex differences in these associations in community-dwelling older adults with amnestic mild cognitive impairment. Design: A cross-sectional study using baseline data from the aerobic exercise and cognitive training (ACT) trial. Setting: The ACT trial conducted exercise testing in an exercise laboratory and data collections in a research facility. Participants: ACT trial participants were recruited through referrals, registries, exhibits, flyers, media, and advertisements and screened for eligibility. To be eligible for this study, ACT enrollees needed complete data on all study variables. Among 146 ACT enrollees, 142 met eligibility for this study (N=142). Interventions: None. Main Outcome Measures: Cardiorespiratory fitness was measured as peak oxygen consumption (Vo2peak) with a peak cycle-ergometer test, executive function with the EXAMINER, episodic memory with the Brief Visuospatial Memory Test-Revised, and global cognition with Montreal Cognitive Assessment. Results: The average age of the sample was 73.8±5.8 years with 16.9±2.9 years of education, with 87.3% White, 51.4% men, and 69.7% married. After controlling for covariates, Vo2peak was significantly related to executive function (b=.037, standard error [SE]=0.015, P=.0154, semipartial [sr] correlation coefficient=.239) and episodic memory (b=.590, SE=0.226, P=.0102, sr=.216), but not global cognition (b=.074, SE=0.055, P=.1837, sr=.125). For men, Vo2peak was significantly associated with executive function (b=.063, SE=0.024, P=.0099, r=.430) and episodic memory (b=1.088, SE=0.312, P=.0009, r=.382). Conclusions: Our findings show that Vo2peak was associated with executive function and episodic memory in the overall sample and in men. Future studies can examine the longitudinal relations between cardiorespiratory fitness and cognition.

Gastrointestinal and Neuropsychological Symptoms Are Associated With Distinct Vomiting Profiles in Patients Receiving Chemotherapy.

OBJECTIVES: To identify subgroups of patients with distinct chemotherapy-induced vomiting (CIV) profiles; determine how these subgroups differ on several demographic, clinical, and symptom characteristics; and evaluate factors associated with chemotherapy-induced nausea and CIV profiles. SAMPLE & SETTING: Adult patients (N = 1,338) receiving cancer chemotherapy. METHODS & VARIABLES: Data were collected on demographic, clinical, and symptom characteristics. Differences among subgroups of patients with distinct CIV profiles were evaluated using parametric and nonparametric tests. RESULTS: Three CIV profiles (None, Decreasing, and Increasing) were identified. Compared with the None class, Decreasing and Increasing classes were more likely to have lower household income and a higher comorbidity burden, as well as to report higher rates of dry mouth, nausea, diarrhea, depression, anxiety, sleep disturbance, morning fatigue, and pain interference. IMPLICATIONS FOR NURSING: Clinicians need to assess common and distinct risk factors for CIV and chemotherapy-induced nausea.

The associations between type 2 diabetes and plasma biomarkers of Alzheimer's disease in the Health and Aging Brain Study: Health Disparities (HABS-HD).

Alzheimer's disease (AD) affects Latinos disproportionately. One of the reasons underlying this disparity may be type 2 diabetes (T2D) that is a risk factor for AD. The purpose of this study was to examine the associations of T2D and AD blood biomarkers and the differences in these associations between Mexican Americans and non-Hispanic Whites. This study was a secondary analysis of baseline data from the observational Health and Aging Brain Study: Health Disparities (HABS-HD) that investigated factors underlying health disparities in AD in Mexican Americans in comparison to non-Hispanic Whites. HABS-HD participants were excluded if they had missing data or were large outliers (z-scores >|4|) on a given AD biomarker. Fasting blood glucose and glycosylated hemoglobin (HbA1c) levels were measured from clinical labs. T2D was diagnosed by licensed clinicians. Plasma amyloid-beta 42 and 40 (Aß42/42) ratio, total tau (t-tau), and neurofilament light (NfL) were measured via ultra-sensitive Simoa assays. The sample sizes were 1,552 for Aß42/40 ratio, 1,570 for t-tau, and 1,553 for NfL. Mexican Americans were younger (66.6±8.7 vs. 69.5±8.6) and had more female (64.9% female vs. 55.1%) and fewer years of schooling (9.5±4.6 vs. 15.6±2.5) than non-Hispanic Whites. Mexican Americans differed significantly from non-Hispanic Whites in blood glucose (113.5±36.6 vs. 99.2±17.0) and HbA1c (6.33±1.4 vs. 5.51±0.6) levels, T2D diagnosis (35.3% vs. 11.1%), as well as blood Aß42/40 ratio (.051±.012 vs. .047±.011), t-tau (2.56±.95 vs. 2.33±.90), and NfL levels (16.3±9.5 vs. 20.3±10.3). Blood glucose, blood HbA1c, and T2D diagnosis were not related to Aß42/40 ratio and t-tau but explained 3.7% of the variation in NfL (p < .001). Blood glucose and T2D diagnosis were not, while HbA1c was positively (b = 2.31, p < .001, ß = 0.26), associated with NfL among Mexican Americans. In contrast, blood glucose, HbA1c, and T2D diagnosis were negatively (b = -0.09, p < .01, ß = -0.26), not (b = 0.34, p = .71, ß = 0.04), and positively (b = 3.32, p < .01, ß = 0.33) associated with NfL, respectively in non-Hispanic Whites. To conclude, blood glucose and HbA1c levels and T2D diagnosis are associated with plasma NfL levels, but not plasma Aß and t-tau levels. These associations differ in an ethnicity-specific manner and need to be further studied as a potential mechanism underlying AD disparities.

The Effects of Exergame Telerehabilitation in Persons With Subjective Cognitive Decline.

BACKGROUND AND OBJECTIVES: The primary aim of this Stage IB randomized controlled trial (RCT) was to test the preliminary effects of a dual-task exergaming telerehabilitation intervention on cognition and aerobic fitness, compared to aerobic exercise (AEx) only and attention control (stretching) in older adults with subjective cognitive decline. RESEARCH DESIGN AND METHODS: This RCT randomized 39 participants on a 2:1:1 allocation ratio to supervised exergame (n = 20), AEx (n = 11), and stretching (n = 8) for 12 weeks. The dual-task exergaming was concurrent moderate-intensity cycling and BrainFitRx cognitive telerehabilitation. Cognition was assessed by NIH Toolbox Cognitive Battery and aerobic fitness by 6-minute walk test (6MWT) and shuttle walk test. RESULTS: The participants were 74.6 (7.4) years old and 69% were female. The effect of time was significant, F(1, 23.9) = 13.16, p = .001, for the Fluid Composite score, and significant within-group changes were seen for the exergame group, t(14.08) = 2.53, p = .024, d = 0.33. Between-group changes did not reach significant levels for any cognitive test. Between-group changes for the 6MWT were not significant. DISCUSSION AND IMPLICATIONS: The exergame participants further improved their fluid cognition, whereas the AEx and stretching groups did not, indicating a potential synergistic effect from AEx and cognitive training. The aerobic fitness changes were similar between the exergame and AEx-only groups, indicating that the feasibility of adding cognitive training to AEx concurrently without sacrificing gains in aerobic fitness from AEx. This study shows the flexibility of exergame delivery and its potentially therapeutic effects in persons at risk for Alzheimer's dementia. CLINICAL TRIAL REGISTRATION NUMBER: NCT04311736.

Perceived Balance, Balance Performance, and Falls Among Community-Dwelling Older Adults: A Retrospective, Cross-Sectional Study.

Objectives: To examine the extent to which older adults' perceived balance, a balance performance test, and fear of falling (FOF) were associated with falls in the last month. Methods: The Health Belief Model served as the theoretical framework. A retrospective, cross-sectional, secondary analysis using data from the National Health and Aging Trends Study was conducted (N = 7499). Results: Multiple logistic regression analysis revealed that the odds of reporting a fall in the past month were 3.3 times (p < .001) greater for participants who self-reported having a balance problem compared to those who did not. The Short Physical Performance Battery and FOF were not uniquely associated with falls. Discussion: Our findings support limited evidence suggesting that older adults' perceived balance is a better predictor of falls than balance performance. Assessing older adults' perceived balance may be a new way to assess older adults' fall risk to prevent future falls.

A test of pre-exposure spacing and multiple context pre-exposure on the mechanisms of latent inhibition of dental fear: A study protocol.

BACKGROUND: Latent inhibition occurs when exposure to a stimulus prior its direct associative conditioning impairs learning. Results from naturalistic studies suggest that latent inhibition disrupts the learning of dental fear from aversive associative conditioning and thereby reduces the development of dental phobia. Although theory suggests latent inhibition occurs because pre-exposure changes the expected relevance and attention directed to the pre-exposed stimulus, evidence supporting these mechanisms in humans is limited. The aim of this study is to determine if two variables, pre-exposure session spacing and multiple context pre-exposure, potentiate the hypothesized mechanisms of expected relevance and attention and, in turn, increase latent inhibition of dental fear. METHODS: In a virtual reality simulation, child and adult community members (ages 6 to 35) will take part in pre-exposure and conditioning trials, followed by short- and long-term tests of learning. A 100ms puff of 60 psi air to a maxillary anterior tooth will serve as the unconditioned stimulus. Pre-exposure session spacing (no spacing vs. sessions spaced) and multiple context pre-exposure (single context vs. multiple contexts) will be between-subject factors. Stimulus type (pre-exposed to-be conditioned stimulus, a non-pre-exposed conditioned stimulus, and an unpaired control stimulus) and trial will serve as within-subject factors. Baseline pain sensitivity will also be measured as a potential moderator. DISCUSSION: It is hypothesized that spaced pre-exposure and pre-exposure in multiple contexts will increase the engagement of the mechanisms of expected relevance and attention and increase the latent inhibition of dental fear. It is expected that the findings will add to theory on fear learning and provide information to aid the design of future interventions that leverage latent inhibition to reduce dental phobia.

A study protocol testing pre-exposure dose and compound pre-exposure on the mechanisms of latent inhibition of dental fear.

BACKGROUND: Dental stimuli can evoke fear after being paired - or conditioned - with aversive outcomes (e.g., pain). Pre-exposing the stimuli before conditioning can impair dental fear learning via a phenomenon known as latent inhibition. Theory suggests changes in expected relevance and attention are two mechanisms responsible for latent inhibition. In the proposed research, we test whether pre-exposure dose and degree of pre-exposure novelty potentiate changes in expected relevance and attention to a pre-exposed stimulus. We also assess if the manipulations alter latent inhibition and explore the possible moderating role of individual differences in pain sensitivity. METHODS: Participants will be healthy individuals across a wide range of ages (6 to 35 years), from two study sites. Participants will undergo pre-exposure and conditioning followed by both a short-term and long-term test of learning, all in a novel virtual reality environment. The unconditioned stimulus will be a brief pressurized puff of air to a maxillary anterior tooth. Pre-exposure dose (low vs. high) and pre-exposure novelty (element stimulus vs. compound stimuli) will be between-subject factors, with stimulus type (pre-exposed to-be conditioned stimulus, a non-pre-exposed conditioned stimulus, and an unpaired control stimulus) and trial as within-subject factors. Pain sensitivity will be measured through self-report and a cold pressor test. It is hypothesized that a larger dose of pre-exposure and compound pre-exposure will potentiate the engagement of the target mechanisms and thereby result in greater latent inhibition in the form of reduced fear learning. Further, it is hypothesized that larger effects will be observed in participants with greater baseline pain sensitivity. DISCUSSION: The proposed study will test whether pre-exposure dose and compound stimulus presentation change expected relevance and attention to the pre-exposed stimulus, and thereby enhance latent inhibition of dental fear. If found, the results will add to our theoretical understanding of the latent inhibition of dental fear and inform future interventions for dental phobia prevention.

Perceived balance and self-reported falls: A retrospective cross-sectional study using the National Health and Aging Trend Study.

AIMS: To examine how perceived balance problems are associated with self-reported falls in the past month after controlling for known correlates of falls among older adults. BACKGROUND: Approximately 30% of adults age 65 and older fall each year. Most accidental falls are preventable, and older adults' engagement in fall prevention is imperative. Limited research suggest that older adults do not use the term 'fall risk' to describe their risk for falls. Instead, they commonly use the term 'balance problems'. Yet, commonly used fall risk assessment tools in both primary and acute care do not assess older adults' perceived balance. DESIGN AND METHOD: The Health Belief Model and the concept of perceived susceptibility served as the theoretical framework. A retrospective, cross-sectional secondary analysis using data from the National Health and Aging Trends Study from year 2015 was conducted. The outcome variable was self-reported falls in the last month. RESULTS: A subsample of independently living participants (N = 7499) was selected, and 10.3% of the sample reported a fall. Multiple logistic regression analysis revealed that the odds of reporting a fall in the past month was 3.4 times (p < .001) greater for participants who self-reported having a balance problem compared to those who did not. In contrast, fear of falling and perceived memory problems were not uniquely associated with falls. Using a mobility device, reporting pain, poor self-rated health status, depression and anxiety scores were also associated with falling. CONCLUSION AND IMPLICATIONS: Older adults' perceived balance problem is strongly associated with their fall risk. Perceived balance may be important to discuss with older adults to increase identification of fall risk. Older adults' perceived balance should be included in nursing fall risk assessments and fall prevention interventions. A focus on balance may increase older adults' engagement in fall prevention.

Mental Health Among Puerto Rican Adolescents Living in the United States During the COVID-19 Pandemic.

OBJECTIVES: The present study examined how different family level (family financial stress, family violence) and individual (food insecurity, gender, race) determinants of health were associated with mental health among Puerto Rican adolescents living in the U.S. during the COVID-19 pandemic. METHOD: A sample consisting of 119 Puerto Rican adolescents, aged 13 to 17, was collected via Qualtrics Panels between November 2020 and January 2021. We examined the association between family financial stress experienced during the pandemic and psychological distress. We also evaluated whether the association between family financial stress and psychological distress was moderated by family violence, food insecurity, and the participant's gender and race. RESULTS: Findings showed that food insecurity positively predicted psychological distress. Results also showed that participants' race moderated the association between family financial stress and psychological distress. Specifically, we found that while there was a significant positive association between family financial stress and psychological distress among Puerto Rican adolescents who identified as a racial minority, this association was nonsignificant among White Puerto Rican adolescents. CONCLUSION: Our research highlights the significant role of COVID-19 related family financial stress and food insecurity on Puerto Rican adolescents' poor mental health during the COVID-19 pandemic.

Higher Levels of Stress and Neuropsychological Symptoms Are Associated With a High Nausea Profile in Patients With Cancer Receiving Chemotherapy.

OBJECTIVES: To evaluate differences in the severity of global, cancer-specific, and cumulative life stress, resilience, and common neuropsychological symptoms among four subgroups of patients with distinct chemotherapy-induced nausea (CIN) profiles. SAMPLE & SETTING: Adult patients with cancer (N = 1,343) receiving chemotherapy. METHODS & VARIABLES: Patients completed stress, resilience, and neuropsychological symptom severity measures. The Memorial Symptom Assessment Scale was used to assess CIN occurrence six times over two cycles of chemotherapy. Parametric and nonparametric statistics were used to evaluate differences among subgroups of patients with distinct CIN profiles. RESULTS: The high class had significantly higher levels of global, cancer-specific, and cumulative life stress; significantly higher levels of depression, anxiety, sleep disturbance, morning and evening fatigue, and pain; and lower levels of morning and evening energy and cognitive dysfunction. IMPLICATIONS FOR NURSING: Clinicians need to evaluate CIN occurrence across each cycle of chemotherapy and assess patients for various types of stress and common neuropsychological symptoms.

Compassion fatigue and COVID-19: A global view from nurses.

BACKGROUND: Due to the rapid spread of COVID-19 variants, the number of people hospitalized for COVID-19 may create psychological burdens on nurses. Nurses with high levels of compassion fatigue (CF) are more likely to make work errors, deliver poor-quality care, and have greater intent to leave their position. OBJECTIVES: This study utilized the social-ecological model to examine factors associated with nurses' CF and compassion satisfaction (CS) during the COVID-19 pandemic. METHODS: Data were collected from the United States, Japan, and South Korea from July to December 2020. The Professional Quality of Life Scale was used to measure burnout (BO), secondary traumatic stress (STS), and CS. RESULTS: Data from 662 responses were used in the analysis. Mean scores were 25.04 (±6.44) for BO, 24.81 (±6.43) for STS, and 37.85 (±7.67) for CS. Multiple regression analyses indicated that resilience and intention to leave nursing were related to each study outcome (i.e., BO, STS, and CS). Greater resilience predicted lower BO and STS but greater CS, whereas intention to leave nursing indicated greater BO and STS, but lower CS. Furthermore, intrapersonal factors and organizational factors (i.e., nurses involved in developing policies to prepare for COVID-19 patients, organizational support, and personal protective equipment [PPE] provisions) were related to BO, STS, and CS. LINKING EVIDENCE TO PRACTICE: To promote nurses' psychological well-being, improvement of organizational factors such as support, PPE, and programs to enhance resilience is recommended to prepare for future emerging infectious disease crises.

Study protocol of an investigation of attention and prediction error as mechanisms of action for latent inhibition of dental fear in humans.

BACKGROUND: Evidence suggests that dental anxiety and phobia are frequently the result of direct associative fear conditioning but that pre-exposure to dental stimuli prior to conditioning results in latent inhibition of fear learning. The mechanisms underlying the pre-exposure effect in humans, however, are poorly understood. Moreover, pain sensitivity has been linked to dental fear conditioning in correlational investigations and theory suggests it may moderate the latent inhibition effect, but this hypothesis has not been directly tested. These gaps in our understanding are a barrier to the development of evidence-based dental phobia prevention efforts. METHODS: Healthy volunteers between the ages of 6 and 35 years will be enrolled across two sites. Participants will complete a conditioning task in a novel virtual reality environment, allowing for control over pre-exposure and the examination of behaviour. A dental startle (a brief, pressurized puff of air to a tooth) will serve as the unconditioned stimulus. Using a within-subjects experimental design, participants will experience a pre-exposed to-be conditioned stimulus, a non-pre-exposed to-be conditioned stimulus, and a neutral control stimulus. Two hypothesized mechanisms, changes in prediction errors and attention, are expected to mediate the association between stimulus condition and fear acquisition, recall, and retention. To ascertain the involvement of pain sensitivity, this construct will be measured through self-report and the cold pressor task. DISCUSSION: Dental phobia negatively affects the dental health and overall health of individuals. This study aims to determine the mechanisms through which pre-exposure retards conditioned dental fear acquisition, recall, and retention. A randomized control trial will be used to identify these mechanisms so that they can be precisely targeted and maximally engaged in preventative efforts.

Distinct Nausea Profiles Are Associated With Gastrointestinal Symptoms in Oncology Patients Receiving Chemotherapy.

BACKGROUND: Unrelieved chemotherapy-induced nausea (CIN) occurs 48% of patients undergoing chemotherapy and is one of the most debilitating symptoms that patients report. OBJECTIVE: The aims of this study were to identify subgroups of patients with distinct CIN profiles and determine how these subgroups differed on demographic and clinical characteristics; severity, frequency, and distress of CIN; and the co-occurrence of common gastrointestinal symptoms. METHODS: Patients (n = 1343) completed demographic questionnaire and Memorial Symptom Assessment Scale 6 times over 2 cycles of chemotherapy. Latent class analysis was used to identify subgroups of patients with distinct CIN profiles. Differences among these subgroups were evaluated using parametric and nonparametric statistics. RESULTS: Four distinct CIN profiles were identified: none (40.8%), increasing-decreasing (21.5%), decreasing (8.9%), and high (28.8%). Compared with the none class, patients in the high class were younger, had a lower annual household income, had child care responsibilities, had a lower Karnofsky Performance Status score and a higher Self-administered Comorbidity Questionnaire score, and were more likely to have received chemotherapy on a 14-day cycle and a highly emetogenic chemotherapy regimen. In addition, patients in the high class reported high occurrence rates for dry mouth, feeling bloated, diarrhea, lack of appetite, abdominal cramps, difficulty swallowing, mouth sores, weight loss, and change in the way food tastes. CONCLUSIONS: That 60% of the patients reported moderate to high CIN occurrence rates confirms that this unrelieved symptom is a significant clinical problem. IMPLICATIONS FOR PRACTICE: Nurses need to evaluate patients' level of adherence to their antiemetic regimen and make appropriate referrals for physical therapy, psychological services, and dietary counseling.

Affective Experience and Regulation via Sleep, Touch, and "Sleep-Touch" Among Couples.

Touch associated with sleep (sleep-touch; reported physical contact during or shortly before/after sleep) is underexplored as a distinct contributor to affect regulatory processes associated with adult sleep. Given the affect-regulating effects of interpersonal touch, we theorized that among healthy co-sleeping adults, sleep-touch would add to sleep-related effects on affective "resetting," resulting in the experience of calmer, more regulated states. We studied 210 married heterosexual couples (aged 20-67 years, 79% non-Hispanic white, 13% Latinx) assigned 14 days of twice-daily (morning/evening) sleep/mood diaries. Multilevel daily (within-couple) mediation analyses showed that as hypothesized, more reported sleep-touch was associated with happier/calmer and less angry/irritable morning mood. In turn, happier/calmer mood was associated with greater enjoyment of time with spouse (for both spouses). Sleep-touch also was linked directly to both evening positive spousal events and enjoyment ratings. Sleep-touch was associated indirectly with fewer negative spousal events and less spouse-related stress via less angry/irritable morning mood (both spouses). Further, wives' sleep-touch was related to happier/calmer husband mood and evening enjoyment; husbands' sleep-touch was unrelated to wives' reports. All associations with sleep-touch were present while accounting for subjective sleep quality, prior evening mood, non-sleep-related physical affection, day in study, and weekend versus weekday. We speculate that among relatively healthy satisfied couples, physical touch during and surrounding sleep may add to sleep's restorative and affect-regulatory functions, suggesting a pathway through which co-sleeping can improve affect regulation and ultimately relationships and health.

The Relationships Between Social Media and Human Papillomavirus Awareness and Knowledge: Cross-sectional Study.

BACKGROUND: Human papillomavirus (HPV) is the most common sexually transmitted infection. HPV can infect both females and males, and it can cause many cancers, including anal, cervical, vaginal, vulvar, and penile cancers. HPV vaccination rates are lower than vaccination rates within other national vaccination programs, despite its importance. Research literature indicates that people obtain health-related information from internet sources and social media; however, the association between such health-seeking behavior on social media and HPV-related behaviors has not been consistently demonstrated in the literature. OBJECTIVE: This study aims to examine the association between social media usage and HPV knowledge and HPV awareness. METHODS: This study analyzed public health data collected through the Health Information National Trends Survey (HINTS) conducted by the US National Cancer Institute. The analysis used data collected in 2020; in total, 2948 responses were included in the analysis. Six HPV-related questions were used to identify HPV awareness, HPV vaccine awareness, and HPV knowledge about HPV-related cancers. Four questions about social media usage and one question about online health information-seeking behavior were used to analyze the associations between social media usage and HPV-related behaviors. Initially, six logistic regressions were conducted using replicate weights. Based on the results, significant factors were included in a second set of regression analyses that also included demographic variables. RESULTS: About half of the respondents were aware of HPV (68.40%), the HPV vaccine (64.04%), and the relationship between HPV and cervical cancer (48.00%). However, fewer respondents were knowledgeable about the relationships between HPV and penile cancer (19.18%), anal cancer (18.33%), and oral cancer (19.86%). Although social media usage is associated with HPV awareness, HPV vaccine awareness, and knowledge of cervical cancer, these associations were not significant after adjusting for demographic variables. Those less likely to report HPV awareness and knowledge included older participants, males, those with a household income of less than US $20,000, those with a formal education equal to or less than high school, or those who resided in a household where adults are not fluent in English. CONCLUSIONS: After adjusting for demographic variables, social media use was not related to HPV knowledge and awareness, and survey respondents were generally not aware that HPV can lead to specific types of cancer, other than cervical cancer. These results suggest that perhaps a lack of high-quality information on social media may impede HPV awareness and knowledge. Efforts to educate the public about HPV via social media might be improved by using techniques like storytelling or infographics, especially targeting vulnerable populations, such as older participants, males, those with low incomes, those with less formal education, or those who reside in the United States but are not fluent in English.

Profiles in Dementia-Related Anxiety: A Latent Profile Analysis.

OBJECTIVES: Dementia-related anxiety (DRA) is the concern about current or future cognitive decline and potential diagnosis of Alzheimer's disease or related dementias (ADRD). Existing research suggests that DRA likely develops due to diverse reasons (e.g., family ADRD history, self-perceived risk, and health-related anxiety), and approaches to managing DRA likely differ as well (e.g., future planning). This study aimed to identify profiles in DRA. METHOD: In a cross-sectional study, a convenience sample of U.S. adults ranging in age from 18 to 82 (N = 492, Mage = 49.25, standard deviation [SDage] = 15.43) completed online assessments of characteristics associated with DRA. Latent profile analysis was used to uncover distinct DRA profiles and promote understanding of individual characteristics associated with varying levels of DRA; multinomial regression assessed if the profiles are further distinguished by covariates. RESULTS: The resulting four-profile model reveals profile differences are largely due to DRA, self-perceived ADRD risk, and preparedness for future care needs; health-related anxiety, age, ADRD exposure, and anticipated ADRD stigma contribute to profile differences as well. Profiles of the youngest and oldest groups reported the lowest and highest levels of preparedness for future care, along with the lowest DRA and self-perceived risk. Several covariates, particularly those assessing general psychological functioning, were also related to profile membership. DISCUSSION: The resulting profiles point to several factors associated with elevated anxiety about ADRD, which do not fully match the risk factors for ADRD.

The Impact of Stereotype Threat on Memory and Cognition in Older Adults.

Cultural stereotypes that equate aging with decreased competence and increased forgetfulness have persisted for decades. Stereotype threat (ST) refers to the psychological discomfort people experience when confronted by a negative, self-relevant stereotype in a situation where their behavior could be construed as confirming that belief. The purpose of this study was to examine the relationships of ST on memory performance in older adults over 24 months. The ST levels on average significantly declined, or improved in the memory training, but not the health training group. Although not significant at the .01 level, the bivariate correlation indicated that change in ST was moderately related to change in verbal memory, suggesting the possibility that improvements (or reductions) in ST may be related to increases in verbal memory scores. We discovered that the unique contribution of ST into the memory performance of healthy older adults offers a possible malleable trait.

Aging through the time of COVID-19: a survey of self-reported healthcare access.

BACKGROUND: Chronic conditions are common and require ongoing continuous management and preventive measures. The COVID-19 pandemic may have affected the management of chronic conditions by delaying care. We sought to understand the impact of personal characteristics (i.e., age) and healthcare factors (i.e., access to a provider) on healthcare access in a sample of Americans 50 years of age or older during COVID-19. METHOD: Participants completed an online survey at the start of the COVID-19 pandemic - the Aging in the Time of COVID Survey. Questions focused on health status, health care access, COVID-19 fear, and social connectedness. Participants were recruited through social media advertisements, list serves, and snowball sampling. Data collection started in early April 2020 and concluded in late May 2020. Logistic regression models examined the results of two key access points: healthcare provider/doctor (n = 481) and medication (n = 765), with 56 and 93% of participants reporting access to a provider and medications, respectively. RESULTS: Individuals with an established primary care provider were much more likely to obtain access to a healthcare provider, OR = 3.81 (95% CI: 1.69, 8.77), and to receive medication, OR = 4.48 (95% CI: 1.61, 11.48), during the time of COVID-19. In addition, access to medication was (a) higher for those who were older, OR = 1.05 (95% CI: 1.01, 1.09), had a higher income (greater than 100 k compared to less than 50 k, OR = 3.04 (95% CI: 1.11, 8.98), and (b) lower for those having caregiving responsibilities, OR = 0.41 (95% CI: 0.21, 0.78), or greater social isolation, OR = 0.93 (95% CI: 0.87, 0.98). CONCLUSIONS: Although most participants had access to medication, just over half had access to a healthcare provider when needed. Notably, health-seeking behaviors for individuals who do not have an established primary care providers as well as those who provide unpaid care, are socially isolated, and younger may require more proactive approaches to care monitoring, management, and maintenance.

Impact of the COVID-19 pandemic on change in sleep patterns in an exploratory, cross-sectional online sample of 79 countries.

OBJECTIVES: To describe changes in sleep patterns during the coronavirus disease 2019 (COVID-19) pandemic, develop profiles according to these patterns, and assess sociodemographic, economic, COVID-19 related, and sleep and mental health factors associated with these profiles. DESIGN, SETTING, AND PARTICIPANTS: A 25-minute online survey was distributed worldwide through social media from 5/21/2020 to 7/1/2020. MEASUREMENTS: Participants reported sociodemographic/economic information, the impact of the pandemic on major life domains, insomnia and depressive symptoms, and changes in sleep midpoint, time-in-bed, total sleep time (TST), sleep efficiency (SE), and nightmare and nap frequency from prior to during the pandemic. Sleep pattern changes were subjected to latent profile analysis. The identified profiles were compared to one another on all aforementioned factors using probit regression analyses. RESULTS: The sample of 991 participants (ages: 18-80 years; 72.5% women; 60.3% residing outside of the United States) reported significantly delayed sleep midpoint, reductions in TST and SE, and increases in nightmares and naps. Over half reported significant insomnia symptoms, and almost two-thirds reported significant depressive symptoms. Latent profile analysis revealed 4 sleep pattern change profiles that were significantly differentiated by pre-pandemic sleep patterns, gender, and various COVID-19-related impacts on daily living such as severity of change in routines, and family stress and discord. CONCLUSIONS: In an international online sample, poor sleep and depressive symptoms were widespread, and negative shifts in sleep patterns from pre-pandemic patterns were common. Differences in sleep pattern response to the COVID-19 crisis suggest potential and early targets for behavioral sleep health interventions.
