From terrible twos to sassy sixes: The development of vocabulary and executive functioning across early childhood.

Across the early childhood period of development, young children exhibit considerable growth in their executive functioning (EF) and vocabulary abilities. Understanding the developmental trajectory of these seemingly interrelated processes is important as both early vocabulary and EF have been shown to predict critical academic and socio-emotional outcomes later in childhood. Although previous research suggests that EF and vocabulary are correlated in early childhood, much of the existing longitudinal research has focused on unidirectional relations among preschool child samples. The current large-scale study, therefore, sought to examine whether children's vocabulary and EF abilities are bidirectionally related over time across four measurement waves in early childhood (i.e., at ages 2, 3, 4, and 6). At each timepoint, children's vocabulary skills were positively correlated with their concurrent EF abilities. After controlling for child sex and maternal education status, the best-fitting, cross-lagged panel model was a unidirectional model whereby children's early vocabulary scores predicted their later EF performance at each timepoint. Although age 2 EF significantly predicted age 3 vocabulary size, this association was no longer significant after accounting for maternal education status. Our results illustrate that vocabulary size plays an important role in predicting children's later EF performance across various timepoints in early childhood, even after controlling for children's initial EF scores. These findings have important implications for intervention research as fostering early vocabulary acquisition may serve as a possible avenue for improving EF outcomes in young children. RESEARCH HIGHLIGHTS: Children's vocabulary size is positively correlated with their concurrent executive functioning skill at ages 2, 3, 4, and 6 Young children's early vocabulary scores predict their later EF performance across measurement waves, even after controlling for initial EF skill There is stability in children's relative vocabulary size and executive functioning performance over time in early childhood.

Barriers to Service Use Among Dementia Family Caregivers in Rural Appalachia: Implications for Reducing Caregiver Overload.

Although the benefits of home- and community-based services (HCBS) to support the needs of older adults are well-established, researchers have persistently reported service underutilization by dementia caregivers to assist them with their caregiving responsibilities. Using the Health Behavior Model and Conservation of Resources Theory, the aim of the current study was to understand what barriers prevent caregivers from using HCBS and the toll it takes on them. Utilizing a sample of 122 rural family caregivers (74% female, 87% white, Mage = 64.86 years) of persons living with dementia (PLwD), simultaneous ordinary least square regressions were employed to understand the association between barriers to service use and the current use of support services and personal services, and concurrently on caregiver role overload. Financial barriers, caregiver's reluctance to use services, and their capability of seeking services were associated with lower use of support services. After controlling for need and enabling factors, caregivers who used more support services, and those who reported system complexities to using support services experienced higher role overload. Financial barriers, system complexities, and caregivers' reluctance also affected the use of personal care services. Despite the use of personal services, caregivers of PLwD with greater needs and fewer enabling factors experienced higher role overload. Study findings suggest that reducing system complexities of HCBS and improving prevention and intervention efforts to facilitate caregivers' awareness of HCBS are needed to address lack of service use and reduce caregiver overload.

Extended Family Caregivers for Persons Living With Dementia.

Despite changes in the structure of contemporary families, little is known about extended family members-siblings, grandchildren, nieces/nephews, stepkin-who are primary caregivers for a relative living with dementia. Information about these caregivers is needed to help ensure their needs are understood by providers in health care and social service settings. The focus of this research was on the care situations of extended family caregivers and the impact of caregiving on their health and well-being. In Study 1, data from the National Study of Caregiving were used to describe the experiences of 107 extended family caregivers. In Study 2, case study techniques elicited additional information about the experiences of 10 extended family caregivers. Collectively, these caregivers provide care with little or no formal support and occasional help from a small informal network. Caregiving affected their physical and emotional health, depending on the strength of the relationship between the caregiver and the person living with dementia and the type of care provided. Findings contribute new knowledge about extended family caregivers and highlight the important role extended family dementia caregivers play and the challenges they face.

Couples Facing Skin Cancer in Old Age: A Dyadic Investigation of Partner Support and Quality of Life.

This study investigated perceived support received by partners and its association with quality of life (QOL) in older couples facing skin cancer. Thirty couples (n = 60; MAge = 70) in which one partner had a skin cancer diagnosis (PwSC) completed either online or paper surveys about their skin cancer diagnosis, perceived partner support, and overall QOL. Actor-partner interdependence models revealed that when PwSCs reported overprotection from their healthy partners (HPs), they were more likely to report lower QOL. Protective buffering received by HPs was negatively associated with their QOL as well as their PwSCs QOL. Active engagement support, however, was not associated with either partner's QOL. While couples may use all three styles of relationship-focused support, protective buffering and overprotection affected each partner's QOL. Implications of the study findings for interventions for couples facing illnesses like skin cancer are discussed.

Depressive symptoms among adult children caregivers in China: moderating effects of working status and gender.

Objectives: With over one-fifth of the world's older population, shrinking family size and increasing number of women in the workforce, elder care is a growing challenge for families in mainland China. This study explored the moderating effect of working status and gender on caregiving time and depressive symptoms among adult children caregivers in mainland China. Method: Participants were 660 adult children caregivers from a nationally representative sample of individuals aged 45 + (N = 13,204) who participated in the China Health and Retirement Longitudinal Study (CHARLS) Wave 2 (2013). Multiple linear regression was used to analyze the direct effect of caregiving time and the moderating effects of working status and gender on symptoms of depression among caregivers. Results: Significant main effect between caregiving time and depressive symptoms was found controlling for demographic covariates. The three-way interaction between working status, gender and caregiving time was also significant. Working status and gender moderate the effect of caregiving time on depressive symptoms: among employed men and women caregivers, spending more hours providing care predicted fewer depression symptoms. Unemployed men caregivers who spent more hours providing care showed highest level of depressive symptoms. Conclusion: The relationship between caregiving time and depressive symptoms was moderated by working status and gender. Future research is needed to explore factors that influence changes in caregivers' health and well-being over time.

The δ13C Value of Fingerstick Blood Is a Valid, Reliable, and Sensitive Biomarker of Sugar-Sweetened Beverage Intake in Children and Adolescents.

Background: Reliance on self-reported dietary intake methods is a commonly cited research limitation, and dietary misreporting is a particular problem in children and adolescents. Objective indicators of dietary intake, such as dietary biomarkers, are needed to overcome this research limitation. The added sugar (AS) biomarker δ13C, which measures the relative abundance of 13C to 12C, has demonstrated preliminary validity in adults. Objective: The purpose of this investigation was to determine the comparative validity, test-retest reliability, and sensitivity of the δ13C biomarker to detect AS and sugar-sweetened beverage (SSB) intake using fingerstick blood samples in children and adolescents. Methods: Children (aged 6-11 y, n = 126, 56% male, mean ± SD age: 9 ± 2 y) and adolescents (aged 12-18 y, n = 200, 44% male, mean ± SD age: 15 ± 2 y) completed 4 testing sessions within a 3-wk period. Participants' height, weight, demographic characteristics, and health history were determined at the first session; 24-h recalls were obtained at each visit and fingerstick blood samples were collected at visits 1 and 3. Samples were analyzed for δ13C value using natural abundance stable isotope mass spectrometry. δ13C value was compared with dietary outcomes in the full sample, and in child and adolescent subgroups. t Tests and correlational analyses were used to assess biomarker validity and reliability, whereas logistic regression and area under the receiver-operator characteristic curve (AUC) were used to evaluate sensitivity. Results: Reported mean ± SD AS consumption was 82.2 ± 35.8 g/d and 329 ± 143 kcal/d, and SSB consumption was 222 ± 243 mL/d and 98 ± 103 kcal/d. Mean δ13C value was -19.65 ± 0.69‰, and was lower in children than in adolescents (-19.80 ± 0.67‰ compared with -19.56 ± 0.67‰, P = 0.002). δ13C values were similar across sessions (visit 1: -19.66 ± 0.68‰; visit 3: -19.64 ± 0.68‰; r = 0.99, P < 0.001) and were associated (P < 0.001) with intake of total AS (grams, kilocalories: r = 0.29) and SSB (milliliters, kilocalories: r = 0.35). The biomarker was able to better discriminate between high and low SSB consumers than high and low AS consumers, as demonstrated by the AUC (0.75 and 0.62, respectively). Conclusions: The δ13C biomarker is a promising, minimally invasive, objective biomarker of SSB intake in children and adolescents. Further evaluation using controlled feeding designs is warranted. Registered at clinicaltrials.gov as NCT02455388.

Short-term changes in added sugar consumption by adolescents reflected in the carbon isotope ratio of fingerstick blood.

BACKGROUND: Consumption of added sugars (AS) and sugar-sweetened beverages (SSB) may adversely affect adolescents' weight and cardiovascular disease risk. Reliance on self-reported dietary assessment methods is a common research limitation, which could be overcome by dietary intake biomarkers. AIM: The investigation was a proof-of-concept study to evaluate the proposed carbon isotope ratio (δ13C) biomarker of AS intake in adolescents, using a controlled feeding design. METHODS: Participants (n = 33, age 15.3 years, 53% female) underwent two seven-day controlled feeding periods in a randomly assigned order. Diets were matched in composition except for AS content (5% or 25% of total energy). Fasting fingerstick blood samples were collected daily during each diet period. RESULTS: Fingerstick δ13C values changed from day 1 to 8 by -0.05 ± 0.071‰ on 5% AS, and +0.03 ± 0.083‰ on 25% AS (p ≤ 0.001). Reliability was demonstrated between day 7 and 8 δ13C values on the 5% (ICC = 0.996, p ≤ 0.001) and 25% (ICC = 0.997, p ≤ 0.001) AS diets. CONCLUSIONS: Larger scale investigations are warranted to determine if this technique could be applied to population-level research in order to help assess the effectiveness of interventions aimed at reducing the consumption of AS or SSB intake.

The role of compassion, suffering, and intrusive thoughts in dementia caregiver depression.

OBJECTIVES: Exposure to suffering of a relative or friend increases the risk for psychological and physical morbidity. However, little is known about the mechanisms that account for this effect. We test a theoretical model that identifies intrusive thoughts as a mediator of the relation between perceived physical and psychological suffering of the care recipient and caregiver depression. We also assess the role of compassion as a moderator of the relation between perceived suffering and intrusive thoughts. METHODS: Hispanic and African American caregivers (N = 108) of persons with dementia were assessed three times within a one-year period. Using multilevel modeling, we assessed the mediating role of intrusive thoughts in the relation between perceived physical and psychological suffering and CG depression, and we tested moderated mediation to assess the role of caregiver compassion in the relation between perceived suffering and intrusive thoughts. RESULTS: The effects of perceived physical suffering on depression were completely mediated through intrusive thoughts, and compassion moderated the relation between physical suffering and intrusive thoughts. Caregivers who had greater compassion reported more intrusive thoughts even when perceived physical suffering of the CR was low. For perceived psychological suffering, the effects of suffering on depression were partially mediated through intrusive thoughts. DISCUSSION: Understanding the role of intrusive thoughts and compassion in familial relationships provides new insights into mechanisms driving caregiver well-being and presents new opportunities for intervention.

Questionnaires for outcome expectancy, self-regulation, and behavioral expectation for resistance training among young-old adults: development and preliminary validity.

The purpose of the present research was to develop questionnaires to assess outcome expectancy for resistance training (RT), behavioral expectation in the context of perceived barriers to RT, and self-regulation strategies for RT among young-old adults (50-69 years). Measurement development included (a) item generation through elicitation interviews (N = 14) and open-ended questionnaires (N = 56), (b) expert feedback on a preliminary draft of the questionnaires (N = 4), and (c) a quantitative longitudinal study for item-reduction and psychometric analyses (N = 94). Elicitation procedures, expert feedback, and item reduction yielded four questionnaires with a total of 33 items. Positive outcome expectancy (α = .809), negative outcome expectancy (α = .729), behavioral expectation (α = .925), and self-regulation (α = .761) had-with one exception-moderate bivariate associations with two different indicators of self-reported RT behavior at one-month follow-up (r = .298 to .506). The present research provides preliminary support for newly developed questionnaires to facilitate understanding of the psychosocial determinants of RT among young-old adults.

Factors Associated with Nursing Home Admission after Stroke in Older Women.

BACKGROUND: We examined the social and economic factors associated with nursing home (NH) admission in older women, overall and poststroke. METHODS: The Women's Health Initiative (WHI) included women aged 50-79 years at enrollment (1993-1998). In the WHI Extension Study (2005-2010), participants annually reported any NH admission in the preceding year. Separate multivariate logistic regression models analyzed social and economic factors associated with long-term NH admission, defined as an admission on 2 or more questionnaires, overall and poststroke. RESULTS: Of 103,237 participants, 8904 (8.6%) reported NH admission (2005-2010); 534 of 2225 (24.0%) women with incident stroke reported poststroke NH admission. Decreased likelihoods of NH admission overall were demonstrated for Asian, Black, and Hispanic women (versus whites, adjusted odds ratio [aOR] = .35-.44, P < .001) and women with higher income (aOR = .75, 95% confidence interval [CI] = .63-.90), whereas increased likelihoods of NH admission overall were seen for women with lower social support (aOR = 1.34, 95% CI = 1.16-1.54) and with incident stroke (aOR = 2.59, 95% CI = 2.15-3.12). Increased odds of NH admission after stroke were demonstrated for women with moderate disability after stroke (aOR = 2.76, 95% CI = 1.73-4.42). Further adjustment for stroke severity eliminated the association found for race/ethnicity, income, and social support. CONCLUSIONS: The level of care needed after a disabling stroke may overwhelm social and economic structures in place that might otherwise enable avoidance of NH admission. We need to identify ways to provide care consistent with patients' preferences, even after a disabling stroke.

Associations between self-rated health and personality.

OBJECTIVE: The goal of our study was to examine how Big Five personality factors predict variability in self-rated health in a sample of older African Americans from the Baltimore Study of Black Aging. METHODS: Personality was measured by the NEO Personality Inventory-Revised, and self-rated health was assessed by the Health Problems Checklist. PARTICIPANTS: The study sample had 202 women and 87 men. Ages ranged from 49 to 90 years (M = 67.2 years, SD = 8.55), and average years of formal education was 10.8 (SD = 3.3). RESULTS: Multiple linear regressions showed that neuroticism and extraversion were significant regression predictors of self-rated health, after controlling for demographic factors. CONCLUSIONS: These findings suggest individual personality traits may influence health ratings, behaviors, and decision-making among older African Americans.

Dementia Care in Rural Appalachia: Multilevel Analysis of Individual- and County-Level Factors.

BACKGROUND AND OBJECTIVES: Home- and community-based services (HCBS) are underutilized, despite offering significant health benefits to both care recipients and caregivers. Drawing upon Andersen's extended behavioral model of health services use, we examined individual- and county-level factors influencing HCBS utilization for dementia care in rural Appalachia. RESEARCH DESIGN AND METHODS: We analyzed data from telephone interviews with 123 dementia family caregivers in rural Appalachian counties (Mage = 64.7, SDage = 12.2). Multilevel analyses were conducted to examine the effects of individual-level and county-level factors on the use of home-based services (home healthcare and personal care services) as well as community-based services (adult day care and transportation services). RESULTS: Results indicated that caregivers' receipt of informal support from family or friends was associated with more use of home-based services (B = 0.42, p = .003). Conversely, longer travel times to service providers were linked to use of fewer community-based services (B = -0.21, p < .001). Residing in counties with more home health agencies was associated with higher utilization of home-based services (B = 0.41, p = .046). However, higher county tax expenditures for HCBS were not linked to home-based or community-based service use. DISCUSSION AND IMPLICATIONS: Findings suggest that informal support in caring for the person living with dementia enables HCBS use in rural Appalachia. In contrast, limited geographic accessibility and service availability can impede HCBS use in rural regions. Policymakers are urged to allocate direct public funding to service providers to expand service availability in underresourced rural regions.

Family Caregivers' Management of Behavioral Expressions of Dementia.

BACKGROUND AND OBJECTIVES: Behavioral expressions of dementia are often stressful for family caregivers to manage as they strive to ensure their relative's needs are met. Guided by Lazarus and Folkman's Transactional Model of Stress and Coping, we identified specific behaviors that disrupt daily routines and challenge the achievement of caregiving goals, and the approaches and strategies caregivers employ to address them. RESEARCH DESIGN AND METHODS: We conducted semistructured interviews with 30 family caregivers in rural Appalachia caring for a relative living with dementia. Analysis involved use of open and focused coding processes to identify the ways caregivers managed behaviors and bar graphs to examine management approaches relative to categories of behaviors and caregiver demographic and emotional well-being variables. RESULTS: Analyses revealed 10 types of behavioral expressions of dementia associated with confusion, irritability, and resistance to engaging in necessary activities of daily living. Caregiver approaches to managing behaviors included gentle persuasion, being harsh by yelling or threatening, being persistent in expecting the person with dementia to complete the tasks at hand, disengaging by postponing the activity, and employing a combination of strategies. Approaches differed across types of behavior and caregiver demographics and had varying effects on caregiver well-being. DISCUSSION AND IMPLICATIONS: Uncovering specific behaviors family caregivers of persons living with dementia found bothersome, caregivers' adaptive strategies for managing behaviors, and the impact of those approaches provides new information to inform training on effective dementia caregiving practices and development of targeted intervention programs for dementia care.

Ultra-processed food intake, gut microbiome, and glucose homeostasis in mid-life adults: Background, design, and methods of a controlled feeding trial.

BACKGROUND: Aging is associated with gut dysbiosis, low-grade inflammation, and increased risk of type 2 diabetes (T2D). Prediabetes, which increases T2D and cardiovascular disease risk, is present in 45-50% of mid-life adults. The gut microbiota may link ultra-processed food (UPF) with inflammation and T2D risk. METHODS: Following a 2-week standardized lead-in diet (59% UPF), adults aged 40-65 years will be randomly assigned to a 6-week diet emphasizing either UPF (81% total energy) or non-UPF (0% total energy). Measurements of insulin sensitivity, 24-h and postprandial glycemic control, gut microbiota composition/function, fecal short chain fatty acids, intestinal inflammation, inflammatory cytokines, and vascular function will be made before and following the 6-week intervention period. Prior to recruitment, menus were developed in order to match UPF and non-UPF conditions based upon relevant dietary factors. Menus were evaluated for palatability and costs, and the commercial additive content of study diets was quantified to explore potential links with outcomes. RESULTS: Overall diet palatability ratings were similar (UPF = 7.6 ± 1.0; Non-UPF = 6.8 ± 1.5; Like Moderately = 7, Like Very Much = 8). Cost analysis (food + labor) of the 2000 kcal menu (7-d average) revealed lower costs for UPF compared to non-UPF diets ($20.97/d and $40.23/d, respectively). Additive exposure assessment of the 2000 kcal UPF diet indicated that soy lecithin (16×/week), citric acid (13×/week), sorbic acid (13×/week), and sodium citrate (12×/week) were the most frequently consumed additives. CONCLUSIONS: Whether UPF consumption impairs glucose homeostasis in mid-life adults is unknown. Findings will address this research gap and contribute information on how UPF consumption may influence T2D development.

Vigilance, risk, and service use among caregivers of people living with dementia.

OBJECTIVE: The purpose of this investigation was to understand the dynamics among dementia caregiving, vigilance, and home and community-based service use. METHODS: This paper is derived from a larger, mixed-methods study on caregiving. We used a descriptive qualitative approach to analyze interview data of 30 family caregivers of relatives with dementia. RESULTS: We found five domains of vigilance in which caregivers felt "on duty": ensuring attentiveness, ensuring safety, ensuring resources, ensuring healthcare, and ensuring closeness. Formal service use did not necessarily give caregivers relief from vigilance, with the language of risk often employed by caregivers. CONCLUSION: Because service use could contribute to feelings of vigilance, rather than give caregivers a break from a sense of watchfulness, these findings support calls for dementia-specific training for service providers. In future caregiving research, the relationship between vigilance, caregiver distress, and role captivity should be explored.

COVID-19 Vaccination Experiences of Family Caregivers of Persons Living with Dementia in Rural Appalachia.

The study investigated COVID-19 vaccine acceptance, hesitancy, and barriers among family caregivers of rural community-dwelling persons living with dementia (PLwD). Three waves of telephone interviews with 26 family caregivers (96% White, 81% Female, Mage = 63 ± 12 years) were analyzed using thematic content analysis. At Wave 3, although all dyads were eligible, only 10 dyads had received their first dose of the vaccine. In 10 dyads, neither person had received the vaccine; in2 dyads, the caregivers did but the PLwD did not; and in 4 dyads, the caregiver did not but the PLwD did. Perceived direct and indirect health risks, cues from trusted allies, and ability to overcome vaccination barriers affected COVID-19 vaccination acceptance. Vaccine refusals were motivated by a low perceived risk of COVID-19, vaccine fear, and personal beliefs. Findings have implications for administration of preventative care practices for dementia family caregivers living in remote locations during a public health emergency.

Financial Fraud of Older Adults During the Early Months of the COVID-19 Pandemic.

BACKGROUND AND OBJECTIVES: Coronavirus disease 2019 (COVID-19) created a "perfect storm" for financial fraud targeting older adults. Guided by the Contextual Theory of Elder Abuse, we focused on individual and systemic contexts to examine how older adults became prey to financial fraud. RESEARCH DESIGN AND METHODS: In July 2020, 998 adults who were 60-98 years of age (93% White; 64% female) completed an online survey about experiences with financial fraud. Participants were recruited from gerontology research registries at Florida State University, University of Pittsburg, Virginia Tech, and Wayne State University. RESULTS: Over half (65.9%) of the respondents experienced a COVID-19-related scam attempt, with charity contributions (49%) and COVID-19 treatments (42%) being the most common. Perpetrators commonly contacted older adults electronically (47%) two or more times (64%). Although most respondents ignored the request (i.e., hung up the phone and deleted text/e-mail), 11.3% sent a requested payment, and 5.3% provided personal information. Predictors of vulnerability included contentment with financial situation, concern about finances in the aftermath of the pandemic, and wishing to talk to someone about financial decisions. Respondents targeted for a non-COVID-19 scam attempt were less likely to be targets of a COVID-19-related scam. DISCUSSION AND IMPLICATIONS: Older adults who were financially secure, worried about their financial situation, or wished they could speak with someone about their financial decisions appeared susceptible to falling victim to a fraud attempt. The high number of attempts indicates a need for a measurable and concerted effort to prevent the financial fraud of older adults.

Kin relationship of caregivers and people with dementia: stress and response to intervention.

OBJECTIVE: This study examined the effects of kin relationship on response to use of adult day services (ADS) on feelings of overload, depressive symptoms, and positive affect for family caregivers of people with dementia. METHODS: The sample consisted of 341 participants drawn from two studies of ADS. The studies used a quasi-experimental design, comparing family caregivers enrolling their care receiver with dementia in an ADS program to a control group not using ADS. Using multilevel model analysis, we examined the main and interaction effects of kin relationship (wife vs. daughters/daughters-in-law), intervention (ADS vs. non-ADS users), and time (baseline, 3 months, and 12 months) on overload, depressive symptoms, and positive affect. RESULTS: Kin relationship affected the response to intervention but in a somewhat different way for each outcome measure. For depressive symptoms, both wives and daughters using ADS had lower scores over time compared to controls. Both wives and daughters using ADS had lower feelings of overload over time, but daughters had a greater decline and wives' scores on this measure dropped only to the level found among controls. For positive affect, wives using ADS showed a considerable decline over time. CONCLUSIONS: These findings suggest that kin relationship is an important moderator of caregivers' response to intervention and warrant more attention both in the design and evaluation of interventions with family caregivers.

Dietary biomarkers: advances, limitations and future directions.

The subjective nature of self-reported dietary intake assessment methods presents numerous challenges to obtaining accurate dietary intake and nutritional status. This limitation can be overcome by the use of dietary biomarkers, which are able to objectively assess dietary consumption (or exposure) without the bias of self-reported dietary intake errors. The need for dietary biomarkers was addressed by the Institute of Medicine, who recognized the lack of nutritional biomarkers as a knowledge gap requiring future research. The purpose of this article is to review existing literature on currently available dietary biomarkers, including novel biomarkers of specific foods and dietary components, and assess the validity, reliability and sensitivity of the markers. This review revealed several biomarkers in need of additional validation research; research is also needed to produce sensitive, specific, cost-effective and noninvasive dietary biomarkers. The emerging field of metabolomics may help to advance the development of food/nutrient biomarkers, yet advances in food metabolome databases are needed. The availability of biomarkers that estimate intake of specific foods and dietary components could greatly enhance nutritional research targeting compliance to national recommendations as well as direct associations with disease outcomes. More research is necessary to refine existing biomarkers by accounting for confounding factors, to establish new indicators of specific food intake, and to develop techniques that are cost-effective, noninvasive, rapid and accurate measures of nutritional status.
