Longitudinal associations between gut microbiome diversity and emotional well-being.
Objective: While a significant link between emotional well-being (EWB) and the gut microbiome has been reported recently, their temporal relationships remain elusive. This study aims to fill this gap by examining the longitudinal associations between EWB and the Shannon Index (SI), an indicator of gut microbiome diversity. Method: The analysis focused on a dataset that collected participants’ current EWB and fecal samples in both 2019 and 2022 (N = 57, 56.1% female, Mage = 52.47 years, SD = 12.65). Gut microbiome profiles were generated by sequencing the 16S rRNA gene, from which SI was subsequently calculated. Results: The cross-lagged panel analysis revealed significant positive cross-sectional associations between EWB and SI in both 2019 (β = .296, SE = 0.121, p = .014) and 2022 (β = .324, SE = 0.119, p = .006). However, no significant longitudinal associations were found between 2019 EWB and 2022 SI (β = .068, SE = 0.138, p = .623), nor between 2019 SI and 2022 EWB (β = −.016, SE = 0.13, p = .899). Conclusions: Our findings indicate that emotional happiness may be associated with gut microbiome profiles at a particular time point, but they may not serve as predictive factors for each other over time. Future research is needed to establish causal relationships between them. (PsycInfo Database Record (c) 2024 APA, all rights reserved)
Personal and illness identity in youth with type 1 diabetes: Developmental trajectories and associations.
Objective: Having Type 1 diabetes (T1D) may complicate the normative developmental task of personal identity formation in adolescence and emerging adulthood. Besides exploring and committing to identity choices in different life domains, youth with T1D need to integrate their illness into their identity, a process labeled as illness identity. The present study examined whether youth with T1D belonging to different personal identity trajectory classes developed differently on four illness identity dimensions (acceptance, enrichment, engulfment, rejection). Method: This four-wave longitudinal study over a 3-year period used self-report questionnaires to examine how personal identity trajectory classes were related to illness identity over time in youth with T1D (baseline: n = 558; 54% female; age range = 14–25 years). Personal identity trajectory classes were identified using latent class growth analysis. Differential development of the four illness identity dimensions among these personal identity trajectory classes was examined using multigroup latent growth curve modeling. Results: Five personal identity trajectory classes were identified: achievement, foreclosure, moratorium, carefree diffusion, and troubled diffusion. Individuals in achievement and foreclosure displayed highest levels of diabetes integration (i.e., high levels of acceptance and enrichment; low levels of engulfment and rejection), whereas individuals in troubled diffusion displayed lowest levels of illness integration (i.e., low levels of acceptance and enrichment; high levels of engulfment and rejection). Conclusions: The present study confirms that personal identity development relates to illness identity development over time in youth with T1D. Understanding the intricate link between personal and illness identity may help clinicians to tailor their interventions to patients’ individual needs.

Preliminary effects of a rural skin cancer prevention intervention for youths.
Objectives: To pilot and assess the feasibility, acceptability, and preliminary effects of the Rural Adult and Youth Sun (RAYS) protection program, a multilevel skin cancer preventive intervention for young children living in rural U.S. communities, delivered through community-organized team sports. Method: Three rural counties in Utah participated with two receiving the intervention and the third serving as a control. Youth sports leagues were recruited through recreation departments and the study took place from May through October 2021. Intervention leagues received sun protection supplies for players and coaches, educational materials for parents, and coaches were offered training on skin cancer and sun protection behaviors. Results: The RAYS program is both feasible to deliver and acceptable to coaches, parents, and players. The intervention also demonstrates beneficial preliminary effects on components of observed child sun-protective behaviors, coach sun protection behaviors, knowledge of skin cancer prevention recommendations, and self-efficacy in skin cancer prevention. Conclusions: Multilevel interventions for skin cancer prevention among young children can be successfully delivered through community organizations and their settings. A priority moving forward is the identification of ways to optimize delivery of such programs to positively influence skin cancer preventive behaviors among children living in diverse rural areas.

Predicting physical activity and quality of life in coronary heart disease patients: An 18-month path analysis of motivational and emotional factors.
Objective: Investigating factors that promote cardiovascular health outcomes is essential for secondary prevention. In a sample of coronary heart disease patients, we examined the direct and indirect effects of selected psychological factors on physical activity behavior and health-related quality of life (HRQoL) over 18 months. Method: Patient-reported data were collected over three time points. Through structured equation modeling, a longitudinal path analysis was conducted to estimate the indirect effects of baseline HRQoL and cardiac self-efficacy on reported physical activity behavior and HRQoL (evaluated at 18 months) through the mediation of anxiety and depression symptoms, patients’ reported intention to change the behavior, and emotions regulation strategies (evaluated at 9 months). Results: A total of 410 patients were included. Significant indirect effects of baseline HRQoL (β = .05, 95% CI [−0.001, 0.111]) and cardiac self-efficacy (β = .105, 95% CI [0.06, 0.16]) on physical activity behavior were found, with anxiety symptoms and emotions regulation strategies as significant mediators. Additionally, the mediation of reported intention in the association between cardiac self-efficacy and physical activity levels was estimated. At the final follow-up, we also found a significant direct association between physical activity behavior and HRQoL (β = .12, p <.01), which was indirectly impacted by baseline HRQoL (β = .006, 95% CI [0.000, 0.017]) and cardiac self-efficacy (β = .012, 95% CI [0.003, 0.027]). Conclusions: This study underlines the significance of addressing stress management, anxiety symptoms reduction, and cardiac self-efficacy enhancement when targeting better cardiovascular health outcomes. Identifying cardiovascular risk profiles based on these findings may benefit future clinical practice and further inform secondary prevention policy guidelines.

Parallel processes of posttraumatic stress and cardiometabolic dysfunction: A systemic illness of traumatic stress.
Objective: To determine if and how cardiometabolic conditions (MetC) may be associated with posttraumatic stress disorder (PTSD) symptoms over time when controlling for the influence of potentially confounding variables. Method: Parallel process latent growth modeling was applied to self-reported longitudinal data collected from 35,788 World Trade Center 9/11 survivors to determine how the development and course of PTSD symptoms and MetC influence each other when controlling for age, sex, race/ethnicity, preexisting traumas, physical health problems, general psychological distress, smoking, and alcohol use. Results: A unidirectional relationship was found in which the intercept of PTSD symptoms predicted the slope of MetC. Hyperarousal (β = .172) and emotional numbing (β = .171) PTSD symptoms demonstrated the strongest association with MetC changes over and above the effects of control variables and potential confounders. Post hoc analyses indicated that utilization of PTSD-related psychotherapy was associated with decreased early presentations of MetC following trauma, which may have vital implications for the integrated treatment of trauma-exposed individuals. Conclusions: Findings have strong theoretical and clinical implications for conceptualizing traumatic stress reactions as systemic processes and utilizing integrated treatment practices following psychological trauma.

Intraday relations between physical activity and energy intake among behavioral weight loss participants.
Objective: Weight loss results from a negative energy balance, when energy intake (EI) is less than energy expended, e.g., from physical activity (PA). However, PA may impact energy balance beyond energy expenditure alone, through indirect effects on eating behavior. Yet, no research has examined if engaging in PA—a central component of most weight loss programs—is associated with same-day EI among individuals with overweight/obesity pursuing weight loss. Method: Adults (N = 101) with overweight/obesity in a weight loss program were prescribed a reduced-calorie diet and PA regimen (250 min of moderate-to-vigorous PA at midtreatment). For 3 weeks at midtreatment, PA and EI were measured via an accelerometer and self-monitoring app, respectively. Multilevel models examined within-person relations between PA and EI preceding PA (“pre-PA”), acutely following PA (“acute post-PA,” the 2 hr following PA), in the time following the acute post-PA period (“remaining time in day”), and across entire PA days (“full-day”), relative to non-PA matched time periods. Results: EI was higher in the pre-PA and acute post-PA periods. There were no reliable differences in EI during the remaining time in day nor across the full-day on PA days versus within-subject matched non-PA days. There also was insufficient evidence to suggest EI pre-PA, post-PA, or across entire PA days, relative to non-PA matched time periods, was associated with percent weight change. Conclusions: Findings suggest that engaging in PA was associated with different within-person EI patterns compared to non-PA days, though there was little evidence to support that these patterns relate to weight change.

Impact of childhood and adult socioeconomic position on change in functional aging.
Objectives: To examine life-course models by investigating the roles of childhood and adult socioeconomic position (SEP) in longitudinal changes in a functional aging index. Method: Up to eight waves of testing, covering 25 years, were available from the Swedish Adoption/Twin Study of Aging: N = 654, intake age = 50–82. A two-slope latent growth curve model was applied to the data, and the impact of including childhood and adult SEP as covariates of the intercept (at age 70) and slopes (before and after age 70) was tested. Results: Both childhood and adult SEP contributed to the best-fitting model. Childhood SEP was significantly associated with intercept and Slope 1 (before age 70) of the latent growth curve model (p <.05). Association of adult SEP with Slope 2 (after age 70) trended toward significance (p <.10). There was a significant interaction effect of childhood and adult SEP on the intercept (p <.05). As a result, intercept at age 70 was highest and change after age 70 was fastest for those whose SEP decreased from childhood to adulthood. Conclusions: Both childhood and adult SEP impact change in functional abilities with age, supporting both critical period and social mobility models. The social environment is modifiable by policies at local, national, and international levels, and these policies need to recognize that early social disadvantage can have long-lasting health impacts.
