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.

Background: In France, uptake of the recommended human papillomavirus (HPV) vaccination remains low. The vaccine cannot be administered without parental consent, but studies have shown that adolescents can make informed decisions about their health. We aimed at understanding the weight of adolescents' vaccination intention in parents' vaccination decision, using data from parent-adolescent dyads collected at baseline of a randomized trial of vaccine promotion interventions.

Method: About 649 parent-adolescent dyads from 61 middle schools in France independently completed an online questionnaire on their knowledge and attitudes toward HPV vaccination, structured around the seven psychological domains of vaccine readiness (VR). We used multivariate and path analyses to understand the family decision-making process.

Results: HPV vaccination was reported by 50.1% of adolescents and 45.5% of parents. Individual antecedents of VR were poorly correlated within dyads (r = .14-.36). Vaccine intentionality among parents of girls depended both on their own VR (β = .53, p < .001) and on their daughters' vaccine intention (β = .25, p < .001). But among parents of boys, vaccine intention depended only on their own VR (β = .72, p < .001). Adolescents' VR depended more strongly on the social environment's attitude among boys than among girls (β = .54 vs. .34, p < .01).

Conclusions: The defined model showed shared decision processes between parents and adolescent girls, but not boys, which can be understood in the context of a recent expansion of HPV vaccination to boys. Beyond this, it suggests that promotion targeting adolescents and their social environment can have a positive influence on parental intentions.

Objective: Differences in automatic cognitive processes exist among individuals with overweight and obesity, thus there is a need to expand our conceptualization of overweight and obesity to emphasize the predictive utility of these automatic processes, rather than focusing solely on behavioral outputs. Implicit association tests (IATs) may afford a noninvasive method of examining automatic preferences that might contribute to overweight and obesity; namely, preferences for unhealthy foods and sedentary behavior versus healthy foods and physical activity. The purpose of the current study was to examine whether implicit attitudes toward foods and physical activity differed based on body mass index (BMI) status. The relationships between implicit attitudes and key psychosocial factors and health behaviors were also examined.

Method: Participants (N = 127) included undergraduate students with an average age of 19.05 years old (SD = 1.52). Average BMI of the sample was 24.20 (SD = 4.93); 33.8% met criteria for overweight or obesity. Participants completed an IAT and questionnaires.

Results: There were no differences in implicit preferences based on BMI or BMI status. Overall, the sample demonstrated implicit preferences for healthy foods and active words, and preferences were not linked to the corresponding behavioral outputs, though preferences were linked to various indices of emotion and emotion regulation.

Conclusions: Future research should explore an extended model to examine how implicit preferences might impact intentions to engage in protective versus risky obesity-related health behaviors, and the various psychosocial factors that might impact the translation of those preferences and intentions in actual behavioral outputs.

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.

Objective: Women dealing with breast cancer (BC) face many challenges, one of which is the fear of cancer recurrence (FCR). This study examined whether disease severity predicts FCR 6 months after cancer diagnosis through psychological distress and whether cognitive-emotion regulation moderates this effect.

Method: The study sample included 656 women from Italy (27.5%), Finland (31.9%), Israel (19.8%), and Portugal (20.8%) diagnosed with Stages I-III of BC. Participants' age ranged between 40 and 70 years (M = 54.92, SD = 8.22). Participants were tracked following BC diagnosis and at 3 and 6 months follow-up. Participants filled out self-report questionnaires, including the FCR inventory-short form, the Hospital Anxiety and Depression Scale, and the cognitive-emotion regulation questionnaire along with medical-social-demographic data.

Results: Greater disease severity at baseline indicated by higher cancer stage predicted greater psychological distress, which in turn predicted greater psychological distress at 3 months. The latter predicted greater FCR at 6 months. This serial mediation model was moderated by negative cognitive-emotion regulation. The mediating effect of disease severity on FCR through psychological distress was significant only in women with mean or higher levels of negative cognitive-emotion regulation.

Conclusion: This study suggests that facilitating psychological well-being and effective cognitive-emotion regulation in the early stages after a cancer diagnosis may protect women from FCR. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: Childhood trauma may contribute to lifelong health through chronic systemic inflammation. However, associations between childhood trauma and inflammation are mixed, indicating that distinct types of childhood trauma may relate to inflammation differently. Moreover, most studies use a single assessment of inflammatory markers that may not reliably estimate stable interindividual differences. The current study is the first to examine relationships between childhood trauma and an ecologically valid measure of inflammation derived from repeated assessments of interleukin (IL)-6 in daily life. We also examine the possibility that glucocorticoid sensitivity and patterns of daily cortisol may contribute to observed associations. Finally, we explore whether biological sex moderates relationships between childhood trauma and IL-6.

Method: Participants were 283 healthy adults aged 40-64 (57% female, 23% Black, Indigenous, and People of Color) who completed the Childhood Trauma Questionnaire and self-collected dried blood spots at home on 4 days to measure IL-6. Measures of salivary cortisol and blood-based glucocorticoid sensitivity were also assessed.

Results: Childhood trauma was not associated with IL-6 in the sample as a whole. However, exploratory analyses showed that childhood trauma related to IL-6 differently for males and females, such that total trauma and emotional neglect predicted higher IL-6 for males but not females. Results persisted after adjustment for covariates. There was no evidence for indirect effects via cortisol or glucocorticoid sensitivity.

Conclusions: Childhood trauma and, specifically, emotional neglect were associated with IL-6 in daily life among middle-aged males. Additional research is needed to elucidate biological and behavioral pathways underlying these associations. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: To determine the day-to-day associations between minority stressors (i.e., anticipated and experienced discrimination) and sleep health outcomes (i.e., total sleep time (TST), sleep disturbances, and sleep-related impairment) among sexual and gender minority (SGM) people of color.

Method: An online sample of SGM people of color living in the United States participated in a 30-day daily diary study. Daily anticipated and experienced discrimination as well as subjective sleep outcomes were assessed via electronic diaries using validated measures. Wrist-worn actigraphy was used to objectively assess TST. Multilevel linear models (MLMs) were used to estimate the independent associations of daily intersectional minority stressors with subsequent sleep outcomes, adjusted for demographic factors and lifetime discrimination.

Results: The sample included 43 SGM people of color with a mean age of 27.0 years (± 7.7) of which 84% were Latinx, 47% were multiracial, and 37% were bisexual. Results of MLMs indicated that greater report of daily experienced discrimination was positively associated with same-night sleep disturbances, B (SE) = 0.45 (0.10), p < .001. Daily anticipated discrimination was positively associated with sleep-related impairment on the following day, B (SE) = 0.77 (0.17), p < .001. However, daily anticipated and experienced discrimination were not associated with same-night TST.

Conclusions: Findings highlight the importance of considering the differential effects of daily intersectional minority stressors on the sleep health of SGM people of color. Further research is needed to identify factors driving the link between daily minority stressors and sleep outcomes to inform sleep health interventions tailored to this population.

Objectives: This study investigated the causal impact of sleep durations on participants' physical activity (PA) in real-world conditions.

Method: We performed a secondary analysis of PA data from 146 young adults using a randomized crossover design: both restricted (5-6 hr/night) and well-rested (8-9 hr/night) sleep weeks were assessed, with a washout week in between. Sleep and activity were tracked via research-grade actigraphy. Data analysis of PA involved repeated-measures analysis of variance (ANOVA) and regression techniques.

Results: Analysis plans and hypothesis were preregistered before data analysis. The exogenously assigned sleep restriction (SR) treatment reduced nightly sleep an average of 92.65 min (± 40.44 min) compared to one's well-rested sleep treatment. The impact of SR on PA was substantial, leading to a 7% reduction in average hourly PA: 18,081.2 (well-rested) versus 16,818.2 (restricted sleep). Significant findings were revealed in daily, F(1, 6) = 84.37, p < .001, η_p² = 0.934, and hourly comparisons, F(1, 166) = 30.47, p < .001, η_p² = 0.155. Further, sensitivity analysis using a variety of regression specifications also found that exogenously assigned SR decreased average wake-hour activity counts by approximately 4.4%-4.7% (p < .01 in all cases) when controlling for other factors. Exploratory analysis showed the PA effects of SR manifested via reductions in PA intensity with concurrent increases in the proportion of time considered as sedentary.

Conclusions: SR significantly lowered PA by around 7%, characterized by reduced intensity and elevated sedentary behavior in a naturalistic setting. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
