Body-related emotions and subsequent physical activity behaviour: An ecological momentary assessment.

Body-related shame and guilt are theorized to be time-varying affective determinants of physical activity, yet research has predominantly relied on self-report measures of physical activity and between-person associations. To address these limitations, the present study used ecological momentary assessment to examine within- and between-person associations between body-related shame and guilt, and subsequent time spent in moderate-to-vigorous physical activity (MVPA) measured by continuously worn accelerometers. University students (n = 98; 79.6% female; mage = 19.45) were prompted 49 times over seven days to report body-related shame and guilt, and wore activPAL accelerometers to monitor movement behaviours. Higher levels of within-person body-related guilt, but not shame, were associated with increased subsequent time spent in MVPA. Contrary to existing literature, neither body-related shame nor guilt demonstrated a significant association with average levels of MVPA between individuals. These findings support theoretical propositions that body-related guilt may impact engagement in physical activity in daily life.

Body-related self-conscious emotions, self-compassion, and dietary restraint in Canadian undergraduate university students: A multilevel mediation and moderation analysis.

OBJECTIVE: Self-compassion has an inverse association with dietary restraint however, the mechanisms linking self-compassion and dietary restraint are not clear. This study aimed to determine to what extent self-compassion was inversely concurrently related to dietary restraint, indirectly through body-related self-conscious emotions, and to what extent trait self-compassion moderated the concurrent within-person association between body-related self-conscious emotions and dietary restraint. METHOD: Data was collected from 224 Canadian university students who reported on trait self-compassion at baseline and body-related shame, guilt, envy, and embarrassment, and dietary restraint biweekly between November 2020 and August 2021. RESULTS: Results from a 2-1-1 multilevel mediation model showed that trait self-compassion was indirectly concurrently related to dietary restraint through body-related shame, guilt, envy, and embarrassment. Results from the moderation model showed that there was a significant positive concurrent within-person association between body-related shame, envy, and embarrassment, but not guilt, with dietary restraint. These relationships were not moderated by trait self-compassion. DISCUSSION: This study adds to our understanding of the concurrent association between body-related self-conscious emotions and dietary restraint, and the mechanisms through which self-compassion is related to dietary restraint. Given body-related self-conscious emotions were related to dietary restraint at both the within-person and between-person level, both compassion-focused interventions that aim to improve general levels of body-related self-conscious emotions and interventions that aim to overcome spikes in these emotions compared with one's usual level are warranted. PUBLIC SIGNIFICANCE STATEMENT: Negative body-related self-conscious emotions were related to higher levels of dietary restraint both across individuals and within individuals over time; and may play a mechanistic role in linking self-compassion with dietary restraint. Interventions aimed at reducing negative body-related self-conscious emotions are warranted in the prevention of eating disorder psychopathology.

Consequences of daily self-weighing: a pilot study in higher-weight women with a history of breast cancer.

Self-monitoring weight is commonly recommended for higher-weight women with a history of breast cancer, despite evidence demonstrating potentially negative psychological consequences of frequent self-weighing. The extent to which higher-weight women with breast cancer experience emotional and behavioral consequences in response to daily self-weighing is unknown. In this pilot study, women (n = 51) with a history of breast cancer in a behavioral weight management program completed a weeklong daily diary protocol. Participants were asked to self-weigh every morning and report on subsequent weight-related shame and guilt, and end-of-day engagement in compensatory exercise, diet, and purging behaviors. Women reported higher levels of guilt on days when their body weight was higher than usual, and when there was more discrepancy between their current vs. goal weight. Additionally, women engaged in higher levels of compensatory diet behavior on days when they experienced more weight-related guilt than usual. Based on these preliminary findings, daily self-weighing may be associated with harmful emotional and behavioral consequences among higher-weight women with a history of breast cancer.

Body image flexibility and exercise motivation: A two-sample replication study.

Body image flexibility - defined as one's ability to accept positive and negative body-related experiences - is theorized to promote adaptive motivational and behavioural outcomes. To date, there is a dearth of literature examining how body image flexibility is related to exercise motivation, a key predictor of exercise behaviour. The purpose of this study was to examine prospective within- and between-person associations between body image flexibility and autonomous and controlled exercise motivation in two independent samples. In Study 1 (N = 204) and Study 2 (N = 165), university students completed online surveys once a week for three weeks. Findings were consistent across studies, whereby during weeks when participants experienced higher than usual body image flexibility, they reported lower levels of controlled motivation (bs = -0.13 to -0.09, ps < .001). Further, participants with higher average levels of body image flexibility reported lower average scores of controlled motivation (bs = -0.30 to -0.27, ps< .001). Body image flexibility was not associated with autonomous motivation in either study. The findings provide novel insights on the relationship between body image flexibility and exercise motivation and identify body image flexibility as a potential modifiable factor that may be associated with lower controlled exercise motivation in daily life.

Accelerometer-Based Physical Activity and Shape and Weight Concerns Among Youth With Overweight and Obesity: A Pilot Exploratory Ecological Momentary Assessment Study.

Background: A bidirectional association between shape and weight concerns (SWC) and physical activity (PA) has been previously documented. This relationship may be particularly salient among youth with overweight/obesity, given that social marginalization of larger bodies has been associated with elevated SWC and barriers to PA. This pilot study explores reciprocal relationships between momentary SWC and accelerometer-assessed PA behavior. Methods: Youth with overweight/obesity (N = 17) participated in a 14-day ecological momentary assessment protocol, during which they were prompted to respond to questions about SWC several times per day. They also continuously wore Actiwatch 2 accelerometers to capture light and moderate-to-vigorous PA behavior. Results: Hierarchical linear modeling revealed a unidirectional association between SWC and PA, whereby after engaging in a higher duration of PA, participants reported lower SWC. SWC did not predict subsequent PA. Conclusion: The findings support a negative temporal relationship between PA and SWC. While further work is needed to replicate and extend these preliminary findings, they may suggest that PA acutely benefits SWC among youth with overweight and obesity.

An integrative model of weight stigma, body image, and physical activity in adolescents.

Negative weight-related experiences and internalized weight stigma have been associated with poorer body image and reduced physical activity in adolescents. However, exploring body image and physical activity as discrete weight stigma outcomes fails to consider the theoretically- and empirically-supported covariation between the two. The present study tested a novel integrated model of the associations among negative weight-related experiences and internalized weight stigma (via weight-related distress), body image (shame, authentic pride, body appreciation), and physical activity. Canadian adolescents (N = 311, Mage ± SD = 16.00 ± 1.01, 75.5% girls) completed a cross-sectional self-report survey. A structural equation model with maximum likelihood robust estimation was tested. Higher negative weight-related experiences were indirectly associated with poorer body image (i.e., higher shame; lower authentic pride and appreciation) through higher weight-related distress. Authentic pride was associated with moderate-to-vigorous physical activity. Higher negative weight-related experiences were indirectly associated with lower physical activity through higher weight-related distress and lower body-related authentic pride. These findings elucidate targetable individual mechanisms and larger systems that could improve body image and foster physical activity among adolescents who encounter negative weight-related experiences and internalized weight stigma.

Beyond the medals: a cross-sectional study exploring retired elite female athletes' health.

Objectives: Little is known about the impact of elite sport participation on long-term athlete health. We aimed to: (1) describe musculoskeletal, mental health, reproductive/endocrine and cardiovascular characteristics in retired elite female athletes and compare to the general population and (2) explore athletes' perceptions of their elite sport participation and its impact on health. Methods: A 136-item online questionnaire was disseminated to Canadian elite female rowing and rugby athletes >18 years old, >2 years retired from elite competition. Matched general population data were obtained from Statistics Canada when available. Results: Seventy-four (24% response rate) athletes (average age 45 (±9) years; retired 15 (±9) years) completed the questionnaire (30 rowing, 44 rugby athletes). During their career, 63 athletes (85%) experienced a hip/groin, knee, foot/ankle injury, or low back pain, with 42 (67%) reporting ongoing symptoms. Athletes 35-54 years reported worse knee symptoms and quality of life compared with the general population (symptom: p=0.197; d=1.15 [0.66, 1.63]; quality of life: p=0.312 d=1.03 [0.54, 1.51]) while other hip, knee and foot/ankle outcome scores were similar. Retired athletes had lower odds of anxiety (OR=0.155 [95% CI0.062 to 0.384]), greater lifetime/ever odds of amenorrhea (OR=6.10 [95%CI 2.67 to 13.96]) and gave birth when older (p<0.05). Fifty-nine (79%) recalled witnessing or experiencing at least one form of harassment/abuse during their career. Sixty athletes (81%) rated their current health as above average or excellent and 61 (82%) would compete at the same level again if given the choice. Conclusion: These novel insights can inform future preventative efforts to promote positive elite sport-related outcomes for current, former and future female athletes.

Body image self-conscious emotions get worse throughout adolescence and relate to physical activity behavior in girls and boys.

Body image is a commonly-reported factor perpetuating declines in physical activity levels during adolescence. However, the evidence is predominantly qualitative, cross-sectional, and focused on girls. Furthermore, the affective dimension of body image has been overlooked compared to the perceptual (e.g., misrepresentations of body size) and cognitive (e.g., dissatisfaction) dimensions. Affective body image includes a range of self-conscious emotions including guilt, shame, envy, embarrassment, and authentic and hubristic pride. This study examined (i) body-related self-conscious emotions over time, and (ii) associations between body-related emotions and physical activity over five years during early-to-mid adolescence. Potential gender differences were also explored. Self-report data for this study were collected once a year over 5 years as part of the MATCH study. The main analyses involved mixed-effects modeling. Participants (n = 776, 55.8% girls) initially aged 12.6 (SD = 0.6) years who provided data on at least one occasion were included in the analysis. Girls reported higher body-related guilt, shame, envy, and embarrassment than boys, and boys reported higher hubristic pride than girls. Over five years from early to mid-adolescence, body-related shame, guilt, envy, and embarrassment significantly increased for boys and girls, authentic pride did not change, and hubristic pride increased for girls only. Controlling for gender and puberty status, body-related guilt, shame, and embarrassment were negatively, and body-related authentic and hubristic pride were positively, associated with physical activity over time. Body-related envy was not significantly related to physical activity. These findings suggest that adolescents express greater negative body-related self-conscious emotions over time. Since these were negatively related to physical activity, interventions focused on reducing negative body-related emotions and enhancing positive body-related emotions may be valuable in adolescence to help curb declining physical activity.

The Associations Between Adverse Childhood Experiences, Physical and Mental Health, and Physical Activity: A Scoping Review.

BACKGROUND: Adverse childhood experiences (ACEs) may be associated with worse physical and mental health in adulthood, and low physical activity engagement, but the relationships are not fully understood. OBJECTIVES: To establish the scope of the literature exploring associations between ACEs, physical activity, and physical and mental health. METHODS: We conducted this scoping review according to PRISMA-ScR guidelines. We searched MEDLINE, Scopus, SPORTDiscus, and PsycInfo for relevant articles. RESULTS: Eighteen studies were included, 17 observational and 1 randomized controlled trial. The majority of studies were cross-sectional and employed self-reported physical activity and ACE measures. Six studies explored physical health, 9 explored mental health, and 3 explored both. Associations between ACEs and poor physical health outcomes (poor self-reported physical health, inflammation, high resting heart rate, and obesity) were consistently weaker or attenuated among those who were physically active. Physical activity may also moderate the associations between ACEs and depressive symptoms, psychological functioning, and health-related quality of life. CONCLUSION: Associations between ACEs and poor physical and mental health were observed in those with less frequent physical activity engagement, though the majority of evidence relies on cross-sectional observational designs with self-report instruments. Further research is required to determine whether physical activity can prevent or treat poor physical and mental health in the presence of ACEs.
