Advances in wearable technologies now allow modern smartwatches to collect body composition estimates through bioelectrical impedance techniques embedded within their design. However, this technique is susceptible to increased measurement error when postural changes alter body fluid distribution. The purpose of this study was to evaluate the effects of postural orientation on body composition and total body water (TBW) estimates produced by smartwatch bioelectrical impedance analysis (SWBIA) and determine its agreement with criterion measures. For this cross-sectional evaluation, 117 (age: 21.4±3.0 y; BMI: 25.3±5.7 kg/m2) participants (F:69, M:48) completed SWBIA measurements while in the seated, standing, and supine positions, then underwent criterion dual-energy X-ray absorptiometry (DXA) and bioelectrical impedance spectroscopy (BIS) assessments. In the combined sample and females, body fat percent, fat mass, and fat-free mass using SWBIA were significantly different between the supine and standing positions (all p

Higher levels of omega-3 track with longer telomeres, lower inflammation, and blunted sympathetic and cardiovascular stress reactivity. Whether omega-3 supplementation alters the stress responsivity of telomerase, cortisol, and inflammation is unknown. This randomized, controlled trial examined the impact of omega-3 supplementation on cellular aging-related biomarkers following a laboratory speech stressor. In total, 138 sedentary, overweight, middle-aged participants (n = 93 women, n = 45 men) received either 2.5 g/d of omega-3, 1.25 g/d of omega-3, or a placebo for 4 months. Before and after the trial, participants underwent the Trier Social Stress Test. Saliva and blood samples were collected once before and repeatedly after the stressor to measure salivary cortisol, telomerase in peripheral blood lymphocytes, and serum anti-inflammatory (interleukin-10; IL-10) and pro-inflammatory (interleukin-6; IL-6, interleukin-12, tumor necrosis factor-alpha) cytokines. Adjusting for pre-supplementation reactivity, age, sagittal abdominal diameter, and sex, omega-3 supplementation altered telomerase (p = 0.05) and IL-10 (p = 0.05) stress reactivity; both supplementation groups were protected from the placebo group's 24% and 26% post-stress declines in the geometric means of telomerase and IL-10, respectively. Omega-3 also reduced overall cortisol (p = 0.03) and IL-6 (p = 0.03) throughout the stressor; the 2.5 g/d group had 19% and 33% lower overall cortisol levels and IL-6 geometric mean levels, respectively, compared to the placebo group. By lowering overall inflammation and cortisol levels during stress and boosting repair mechanisms during recovery, omega-3 may slow accelerated aging and reduce depression risk.

ObjectiveCancer, particularly, during young adulthood, can evoke difficult emotions, interfere with normative developmental activities, and challenge coping responses. Emotion-regulating coping efforts aimed at active emotional processing (EP) and emotional expression (EE) can be beneficial to cancer adjustment and perceptions of positive growth. However, it may be that EP and EE work differently to influence well-being. This study examines relationships of EP and EE with psychological distress, posttraumatic growth (PTG), and resilience. We expect that EP will be positively associated with PTG and resilience, whereas EE will be negatively associated with psychological distress.MethodsYoung adults with cancer (M age  = 34.68, N = 57) completed measures of emotional; approach coping (EP and EE), psychological distress (depressive symptoms, fear of cancer; recurrence [FCR]) and indicators of positive adjustment and growth (resilience and PTG).ResultsGreater use of EP was associated with higher resilience (β = 0.48, p = 0.003) and PTG (β = 0.27, p = 0.05), whereas greater use of EE was associated with lower resilience (β = -0.33, p = 0.04). The EE × EP interaction was significant for FCR (β = 0.29, p = 0.04) such that low EE was associated with lower FCR in those with high EP. Interaction effects were not significant for depressive symptoms, resilience, or PTG.ConclusionsFindings highlight differing relationships between EP and EE among young adults with cancer. Interventions aimed at increasing emotion-regulating coping strategies may prove useful in facilitating positive adjustment and growth, strengthening young adults' ability to cope with the diverse effects of disease, treatment, and survivorship.

BackgroundWorry increases risk for long-term health issues by prolonging the physiological stress response. In contrast, relaxation may ameliorate the psychological and physiological burden resulting from worry. This study examined the impact of experimentally induced worry and relaxation on cortisol, heart rate variability (HRV), and inflammation.MethodParticipants (N = 80) completed both a worry and relaxation induction (presented in a fixed order) while HRV was collected continuously. Three blood samples were taken (at baseline, after the worry induction, and after the relaxation induction) to measure IL-6, IFN-γ, TNF-α and serum cortisol.ResultsThere were significant changes in IL-6 (p < 0.001), IFN-γ (p < 0.01), HRV (p < .001), and cortisol (p

In this longitudinal study of students with concealable chronic health conditions (CCHCs), we applied components of interpersonal disclosure process models to investigate how illness disclosures and perceived partner responsiveness conferred health and social benefits during the COVID-19 pandemic. Students with CCHCs and in relationships completed online surveys at the beginning, middle, and end of the academic year in which they returned to campus amid the COVID-19 pandemic (n Time1 = 101, n Time2 = 52, n Time3 = 54). Mixed models showed students with greater illness disclosures and perceived partner responsiveness had better physical health, engaged in less health-compromising behaviors, felt less worried and stressed about the COVID-19 pandemic, and experienced lower illness-related stigma, discrimination, and social isolation. Over time, students' greater illness self-disclosures predicted lower health-compromising behaviors and illness-related discrimination. Notably, perceived partner responsiveness connected greater illness self-disclosures to better health, COVID-related, and social-contextual outcomes. These findings demonstrate the health and social benefits of talking openly about concealable illnesses with partners and, in turn, feeling cared for, validated, and understood amid the COVID-19 pandemic. This study provides new evidence on relational pathways to better social and health outcomes among those with heightened health risks. [ABSTRACT FROM AUTHOR]

Background/Objectives: Individuals with mental health conditions such as depression are vulnerable to poor dietary habits, potentially due to the maladaptive eating behaviors often used to regulate negative emotion. However, the specific dietary components most associated with depression, as well as the mediating roles of emotion regulation and other eating behaviors, remains ambiguous in young adults. Methods: For this cross-sectional evaluation, a total of 151 (86 F, 65 M; BMI: 22.0 ± 5.1 kg/m2; age: 21.4 ± 2.5 y) multi-ethnic participants (50 White, 36 Black, 60 Asian, and 5 White Hispanic) completed a digital 24-h dietary recall and self-reported measures of depressive symptoms, emotional regulation, and eating behaviors. LASSO regression was used to identify the dietary variables most associated with each subscale and to remove extraneous dietary variables, and multiple regression and mediation analyses were conducted for the remaining variables. Results: Out of >100 dietary factors included, only added sugar in the combined sample (p = 0.043), and relative sugar in females (p = 0.045), were retained and positively associated with depressive symptoms. However, the relationships between depression and added and relative sugar intake were mediated by craving control and emotional eating, respectively. Individuals with higher added sugar intake (p = 0.012–0.037), and females with higher relative sugar intake (p = 0.029–0.033), had significantly higher odds of risk for major depression disorder and the use of mental health medications. Conclusions: Added and relative sugar intake are significantly associated with depressive symptoms in young adults, but these relationships may be mediated by facets of emotional dysregulation, such as emotional eating and craving control.

A number of studies have shown that self-rated health reliably predicts mortality. This study assessed the impact of perseveration on self-rated health, physical functioning, and physical symptoms (pain, fatigue, breast cancer symptoms) among breast cancer patients. We hypothesized that cancer-related distress would serve as an intervening variable between both worry and rumination and self-rated health, physical functioning, and physical symptoms. Women (N = 124) who were approximately 7 weeks post-surgery but pre adjuvant treatment completed the Impact of Events Scale, the Penn State Worry Questionnaire, and the Rumination Scale. They also rated their pain, fatigue, physical functioning, and self-rated health using the RAND-36 and breast cancer symptoms with the Breast Cancer Prevention Trial Symptom Checklist (BCPT). Covariates included body mass index, age, cancer stage, menopause status, and physical comorbidities. Worry was associated with higher cancer-related distress, which in turn predicted greater pain and breast cancer symptoms, poorer physical functioning, and lower self-rated health. Rumination also predicted greater cancer-related distress, which ultimately contributed to greater pain along with poorer physical functioning and self-rated health. Models with fatigue as an outcome were not significant. These findings suggest that perseveration can heighten cancer-related distress and subsequent perceptions of physical symptoms and health among breast cancer patients prior to adjuvant treatment.

Background Breast cancer survivors often experience many somatic and cognitive side effects resulting from their cancer diagnosis and treatment, including higher rates of pain, fatigue, and memory/concentration problems. Emotion regulation offers opportunities to either enhance or dampen physical health. Purpose In a secondary analysis of a double-blind randomized controlled trial (RCT) using a typhoid vaccine to assess factors associated with breast cancer survivors' inflammatory responses, we assessed how two specific aspects of emotion regulation, mindfulness, and worry, corresponded to acute changes in focus problems, memory problems, and fatigue along with performance on pain sensitivity and cognitive tasks across two visits among breast cancer survivors. Methods Breast cancer survivors (N = 149) completed two 8.5-hr visits at a clinical research center. Survivors were randomized to either the vaccine/saline placebo or a placebo/vaccine sequence. Worry and mindfulness questionnaires provided data on trait-level emotion regulation abilities. Fatigue, memory problems, and focus difficulties were assessed via Likert scales six times—once before the injections and then every 90 min for 7.5 hr thereafter. Women also completed a pain sensitivity task and several cognitive tasks at each visit. Results Findings from this study showed that breast cancer survivors who worried more and were less mindful experienced subjective memory problems, focus problems, and cold pain sensitivity across two visits and irrespective of injection type. Lower mindfulness also corresponded to higher subjective fatigue and hot pain sensitivity and objective ratings. Emotion regulation skills did not predict objective pain sensitivity or cognitive problems. Conclusion Results from this study highlight the benefits of adaptive emotion regulation in helping mitigate symptoms associated with breast cancer survivorship. [ABSTRACT FROM AUTHOR]

Cancer diagnosis and subsequent treatment can impact how young adults make sense of their worlds and disrupt peace of mind. The patient–oncologist therapeutic alliance, built upon mutual care, respect, and trust, may foster a deeper understanding of one's illness and promote peace of mind. The study examined relationships between a comprehensive cancer-specific measure of therapeutic alliance and meaning and peace of mind among young adults with cancer (N = 56). Results indicated that a stronger therapeutic alliance was positively associated with meaning and peace of mind. Findings highlight the importance of the patient–oncologist therapeutic alliance in facilitating positive psychological outcomes among young adults with cancer. [ABSTRACT FROM AUTHOR]
