Objective: Obesity is one of the most prominent health issues in modern society. Although previous research has identified chronic psychological stress as a risk factor for obesity, much of this research only examined how an individual's own stress affects their adiposity. The current study utilized an actor-partner interdependence model to examine the unique associations of youths' and parents' chronic stress with both their own and each other's adiposity.

Method: Five hundred sixty-nine dyads of youths (48.7% females, 49.9% Whites, M_age = 13.70 years) and one of their parents (82.6% females, 58.2% Whites, M_age = 45.38 years) participated in a cross-sectional lab study, where both youths and parents completed interviews and anthropometric measurements. Trained interviewers conducted the UCLA Life Stress Interview to assess chronic psychological stress of youths and parents, respectively. Youth and parent adiposity was measured using three indicators, including body mass index, waist circumference, and body fat percentage.

Results: The actor-partner interdependence model showed that when both youths' and parents' chronic stress were included simultaneously in the model, youths' chronic stress was uniquely associated with both their own and their parents' adiposity, and parents' chronic stress was also uniquely associated with youths' adiposity.

Conclusion: Chronic psychological stress of youths and parents is uniquely associated with each other's adiposity, over and above their own stress. Thus, the psychosocial experiences of close others can be linked to both youth and adult obesity. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: Despite the proven benefits of vaccination, people differ in their willingness to get vaccinated. These differences are the result of multiple factors, including social, cultural, and psychological variables. This meta-analysis estimated the effects of people's Big Five personality traits on their vaccination attitudes, intentions, and behaviors and examined the role of theoretically and empirically derived moderator variables.

Method: We meta-analyzed data from 28 studies that sampled over 48,000 individuals to estimate the effects of Big Five personality traits on vaccination attitudes, intentions, and behaviors. In addition, we tested the moderating effects of age, gender, sample region, sample type (representative vs. convenience), vaccination measure (attitude, intention, behavior, compound), vaccination type (COVID-19, Influenza, or other), and reliability of the Big Five measure on the links between personality traits and vaccination.

Results: People with high levels in agreeableness and extraversion, and low levels in neuroticism reported more positive attitudes toward vaccination, whereas open people reported stronger intentions to get vaccinated. Open and agreeable people were also more positive about novel COVID-19 vaccines, whereas extraverted people were more positive about influenza vaccines. There were no effects for conscientiousness. Overall, effect sizes were small but generalized across age. Other moderator effects suggested a more nuanced picture across cultural regions, sample types, and gender.

Conclusions: The findings provide a compelling picture of significant, albeit small, effects of personality traits on vaccination. Questions remain about the processes through which personality traits may affect vaccination attitudes, intentions, and potentially also behavior.

Objective: Despite the popularity of mindfulness in research and interventions, information is missing about how and why mindfulness may benefit employee sleep health. Drawing from emotion regulation theory, we evaluate affective rumination, negative affect, and positive affect as potential mechanisms. We also explore differential effects of trait and state attentional mindfulness on both subjective (e.g., quality and sufficiency) and actigraphy-measured aspects (e.g., duration and wake after sleep onset) of sleep health.

Method: Ecological momentary assessment and sleep actigraphy data were collected across two independent samples of health care workers (N1 = 60, N2 = 84). Ecological momentary assessment was also used to collect daily information on state mindfulness, affect, and rumination.

Results: Our results support rumination and, to a less consistent extent, negative affect as mediators of the association between mindfulness and sleep health but not positive affect. Trait and state mindfulness demonstrate comparable benefits for employee sleep health, but these benefits largely emerge for subjective sleep dimensions than actigraphy-measured.

Conclusions: These findings support emotion regulation as a sound theoretical framework for sleep and mindfulness research and may support more informed workplace mindfulness interventions. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objectives: To examine the prospective association between perceived everyday discrimination and Type 2 diabetes incidence in a large population-based sample.

Method: Data were from the Health and Retirement Study of 14,900 individuals aged ≥ 50 years without a diabetes diagnosis. Participants self-reported experiences of everyday discrimination and diabetes status. Associations between baseline perceived everyday discrimination (one time point) and incident diabetes in the following 10 years were modeled using Cox regression, adjusting for potential confounders. Exploratory analyses assessed the association between repeated reports of perceived everyday discrimination (reports of everyday discrimination at more than one time point) and later diabetes onset.

Results: A total of 917 (6.15%) of the 14,900 participants developed Type 2 diabetes over a maximum 10-year follow-up (Mdn = 6). Baseline perceived everyday discrimination was prospectively associated with an increased risk of diabetes (hazard ratio = 1.37, 95% confidence interval [1.15, 1.63], p < .001) independent of age, sex, wealth, race and ethnicity, and education. This association was robust to further adjustment for body mass index, hypertension, physical activity, smoking, alcohol consumption, and depression. In exploratory analyses, repeated reports of everyday discrimination were not significantly associated with incident diabetes.

Conclusions: Individuals who perceive everyday discrimination are more likely to develop Type 2 diabetes than those who do not perceive everyday discrimination. Further research is needed to investigate the potential pathways linking discrimination and diabetes onset. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: Most work on place-based (e.g., rural-urban) health disparities has been conducted with population-level data, which is limited in its capacity for causal inferences about individuals and lifespan health. The present study leverages individual-level longitudinal data, spanning up to 29 years, to understand how rurality-urbanicity predicts risk for all-cause mortality; whether these associations hold above and beyond socioeconomic status (SES); and whether the association between rurality-urbanicity and mortality risk varies by sex, SES, race, ethnicity, and partner status.

Method: The present preregistered study uses data from two large longitudinal studies of U.S. Americans (Health and Retirement Study and Midlife in the United States; total N = ∼55,000), who reported on their sociodemographic characteristics, had their addresses linked to geographical indicators (i.e., rural-urban continuum codes), and have data from the National Death Index regarding the vital status and survival time.

Results: Using Cox proportional hazards regression models, findings showed that suburban and rural residents were at a 12% and 18% greater risk for earlier mortality compared to urban residents in Health and Retirement Study, but the associations between rurality-urbanicity and mortality risk were nonsignificant in Midlife in the United States. The longitudinal associations between rurality-urbanicity and mortality risk were largely independent of SES. Finally, there was only one statistically significant interaction effect, suggesting the strength and direction of the association between rurality-urbanicity and mortality risk was largely the same across sociodemographic subgroups.

Conclusions: There is tentative evidence suggesting that rurality-urbanicity is an important social determinant of longevity, over and above other sociodemographic factors. Future studies should explore how to promote longer and healthier lives among rural residents. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: The current study applied survival analysis to examine factors associated with nondisclosure of human immunodeficiency virus (HIV) serostatus among mothers living with HIV (MLH) who had participated in a cognitive-behavioral intervention to disclose their HIV status to their children.

Method: Data were utilized from MLH in the intervention arm of the teaching, raising, and communicating with kids (TRACK; Schulte et al., 2021) trial focusing on serostatus disclosure/nondisclosure across four time points (baseline, 3, 9, and 15 months). MLH (M_age = 39.4) resided in California or Georgia and identified as Latina (33%), Black (54%), White (5%), or multiracial (8%). Physical, mental health, and psychosocial measures from the 3-month assessment were used to predict nondisclosure applying Cox regression survival analysis.

Results: Nondisclosure was associated with MLH reporting better physical and mental health, less conflict with their child, better cohesion within their families, and less perceived stigma. MLH reporting better physical functioning were 58% less likely to disclose compared to those reporting physical limitations (hazard ratio [HR] = 0.42). Those reporting lower levels of disclosure self-efficacy were 59% less likely to disclose than those reporting higher levels (HR = 2.47); by 67 weeks into the study, the nondisclosure rate was 56% for those reporting lower self-efficacy compared to 24% for those reporting higher self-efficacy.

Conclusions: Addressing the inclination not to disclose when the MLH is feeling healthy may be an aspect to incorporate into future interventions. Furthermore, improving disclosure self-efficacy to a high level appears to be a critical component to intervention success. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: Loss of control (LOC) eating (feeling unable to control food type/amount eaten) during pregnancy is common and linked to risk for poor cardiovascular health (CVH), but it is unclear whether prenatal LOC eating directly relates to CVH during pregnancy. The current study tested associations between prenatal LOC eating and CVH during pregnancy in a sample with prepregnancy body mass index (BMI) ≥ 25.

Method: At 12-20 weeks' gestation, participants (N = 124) self-reported: prenatal LOC eating, diet, physical activity, nicotine use, sleep; height/weight were measured. Data were collected during 2015-2017. We dichotomized LOC eating (0 = absent; 1 = present) and scored CVH metrics using Life's Essential 8 to create a composite CVH score (range = 0-100; higher = better). Linear and binary logistic regression models tested if LOC eating is related to composite CVH score and odds of scoring low (0)/moderate-high (1) on each CVH metric, respectively. All models employed propensity score adjustment, since those with/without LOC eating may differ in ways affecting CVH, and covaried for: age, gestational age, prepregnancy BMI, ethnicity, race, education, and income.

Results: Compared to those without, participants with LOC eating had significantly poorer composite CVH scores (b = -9.27, t(111) = -2.70, p < .01) and lower odds of scoring moderate-high on nicotine use (OR = 0.20, 95% CI [0.04, 0.85], p = .03) and sleep duration (OR = 0.19, 95% CI [0.04, 0.83], p = .03) CVH metrics.

Conclusions: Prenatal LOC eating was associated with poorer CVH during pregnancy in this sample with prepregnancy BMI ≥ 25, even after controlling for propensity of experiencing LOC eating and known risk factors for poor CVH. Thus, prenatal LOC may represent a modifiable factor related to prenatal health risk. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: We examined the links of supportive and conflictual peer interactions to mood and self-care via ecological momentary assessment.

Method: Adolescents with Type 1 diabetes (n = 167, 49% female) recruited between 2018 and 2021 were prompted 8 times a day for 8 days to complete brief surveys that measured perceived social interactions, affect, and self-care.

Results: Cross-sectional analyses revealed between- and within-person (WP) links of peer support to positive mood and conflict to negative mood. Between-person peer support was linked to healthy self-care, but WP support was not. Lagged analyses showed conflictual interactions were associated with self-care decline. There was some evidence that females did not benefit as much from support and were more bothered by conflict than others.

Conclusions: Results underscore differences in between- and WP links of social interactions to health. Individual differences in support were more influential than conflict, but conflictual interactions had more momentary effects than supportive interactions.

Objectives: Adverse childhood experiences (ACEs) have been linked to adulthood chronic diseases, but there is little research examining the mechanisms underlying this association. We tested pathways from ACEs to adult disease mediated via risk factors of depression, smoking, and body mass index.

Method: Prospective data from adults 18 to 74 years old from the Hispanic Community Health Study/Study of Latinos and Sociocultural Ancillary Study were used. Retrospectively reported ACEs and hypothesized mediators were measured at Visit 1 (2008-2011). Outcomes of disease prevalence were assessed at Visit 2, approximately 6 years later. The analytic sample includes 5,230 Hispanic/Latino participants with ACE data. Statistical mediation was examined using structural equation modeling on cardiometabolic and pulmonary disease prevalence and reported probit regression coefficients with 95% confidence intervals (CIs).

Results: We found a significant association between ACEs and the prevalence of asthma/chronic obstructive pulmonary disorder (standardized β = .07, 95% CI [0.02, 0.12]). In the mediational model, the direct association was nonsignificant (β = .02, 95% CI [-0.04, 0.07]) but was mediated by depressive symptoms (β = .03, 95% CI [0.02, 0.04]). There were no associations between ACEs and the prevalence of diabetes and self-reported coronary heart disease or cerebrovascular disease. However, a small indirect effect was identified via depressive symptoms and coronary heart disease (β = .02, 95% CI [0.01, 0.03]).

Conclusion: In this diverse Hispanic/Latino sample, depressive symptoms were found to be a pathway linking ACEs to self-reported cardiopulmonary diseases, although the effects were of small magnitude. Future work should replicate pathways, confirm the magnitude of effects, and examine cultural moderators that may dampen expected associations.

Objective: This study investigates the interaction between message framing and point-of-reference (self vs. others) for vaccine benefits on young adults' COVID-19 vaccine confidence and intentions. It also examines how COVID-19-related health beliefs-such as perceived severity of COVID-19 and perceived benefits of obtaining the vaccine to protect others-mediate these interactions.

Method: In a 2 (framing: gain vs. loss) × 3 (reference point: self, others, university community) between-subjects experiment (Fall 2021), 202 participants ages 18-23 were shown animated messages with embedded manipulations to convey vaccine information. Moderated mediation models tested the conditional indirect effects of framing on vaccine confidence and intentions.

Results: Reference point significantly moderated the effect of framing on the perceived severity of COVID-19. More specifically, and somewhat contrary to previous literature, perceived severity was highest when messages emphasized gains for others. In turn, perceived severity correlated positively with vaccine confidence and intentions, resulting in a significant conditional indirect effect. Despite its positive relationship with COVID-19 vaccine confidence and intentions, perceived benefit to others was not a significant mediator.

Conclusion: This study provides evidence for the role of reference point in moderating the effect of gain-loss message framing on COVID-19 vaccine attitudes and intentions. However, the findings differ from past research, suggesting other-gain messages may be an optimal strategy for promoting these vaccine outcomes for young adults. Overall, findings have implications for developing tailored messaging strategies that account for the nature of targeted populations and the evolving perceptions of the disease and its associated messaging campaigns.
