Yoga practice among ethnically/racially diverse emerging adults: Associations with body image, mindful and disordered eating, and muscle-enhancing behaviors

The impact of yoga on body image in adults: A systematic review of quantitative studies

Evidence suggests that yoga can be used as an intervention to improve body image. This systematic review evaluates the evidence of the efficacy of yoga in improving body image among adults. Authors followed PRISMA guidelines, searching Pubmed, Ovid MEDLINE, Embase, Cochrane, CINHAL, PsycInfo, and grey literature up to December 2, 2023 and identifying 446 unique records. Eligibility criteria included English-language, peer-reviewed studies with quantitative data on adult populations. Twenty-nine studies were eligible for inclusion and were evaluated for methodological quality using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach. Interventions focused solely on yoga varied in length, frequency, and style. Our synthesis revealed that yoga is associated with improved body satisfaction and appreciation, as well as reduced body dissatisfaction, across diverse adult populations, including those with clinical or subclinical levels of body dissatisfaction. Most low- and moderate-quality studies reported significant improvements, and some suggested a dose-response relationship. However, the evidence is limited by methodological weaknesses, such as a lack of blinding and inadequate reporting. Despite these limitations, findings support yoga as a promising intervention for improving body image in adults. Future research should aim for methodologically rigorous studies that use validated outcome measures and more inclusive populations.

Do parents engage in weight- and health-focused conversations with their emerging adult children and are there cross-sectional associations with weight and well-being outcomes?

BACKGROUND

Research indicates harmful associations between parental weight-focused conversations and markers of pediatric health and well-being. However, little is known about the prevalence and consequences of parent conversations focused on weight or health behaviors (i.e., physical activity or nutrition) with emerging adult children.

METHODS

Data are from the 2018 follow-up survey of the population-based EAT 2010-2018 (Eating and Activity over Time) in cohort from Minneapolis-St. Paul, MN. Participants were emerging adults at follow-up with ages 18-26. Regression models adjusted for sociodemographic characteristics were conducted.

RESULTS

Over two-thirds (68%) of mothers and 44% of fathers engaged in weight-focused conversations with their emerging adult children; 25% of both parents reported engaging in conversations focused only on health behaviors; and 8% of mothers and 26% of fathers reported not engaging in either type of conversation. Health-focused conversations by both parents were associated with lower body mass index (BMI) and disordered eating behaviors, higher intake of fruit and vegetables, and psychosocial well-being in emerging adult children. Weight-focused conversations with both parents were associated with higher BMI and disordered eating behaviors in emerging adults. There were gender moderated associations of paternal conversations about weight and health with vegetable intake, binge eating, and depressive symptoms.

DISCUSSION

The high prevalence and negative health outcomes associated with weight-focused conversations coupled with the low prevalence and positive health outcomes associated with health-focused conversations by parents suggests the need for public health messaging and intervention development aimed at reducing parental weight talk with emerging adult children.

The Role of Mindfulness Therapy in the Treatment of Chronic Pain

PURPOSE OF REVIEW

Mindfulness therapy is a widely used treatment for many diseases and has been shown to improve pain-related functions. There is growing support for the use of psychotherapy in the treatment of chronic pain. While studies have shown a positive effect of mindfulness therapy, it is important to consider psychosocial factors as there are still a small number of studies that question its effectiveness.

RECENT FINDINGS

Based on current studies, mindfulness therapy involves cognitive factors related to chronic pain, both in terms of cognitive production and its impact on cognitive control. Psychological and neurobasic studies were reviewed to provide a deeper understanding of these components, which include thought inhibition, attention deficit, pain catastrophizing, and self-efficacy. Mindfulness therapy has the potential to normalize psychology and nerves, and increase internal and external connectivity to work networks related to stress perception, cognition, and emotion. However, further research is needed to fully understand its effects. By exploring the relationship between mindfulness therapy and chronic pain. This review provides a new avenue for future research in psychotherapy for patients with chronic pain.

Associations of regular consumption of breakfast, lunch and dinner with Body Mass Index during adolescence: longitudinal findings by weight status among the Eating and Activity over Time 2010-2018 cohort

OBJECTIVE

To examine how the associations between meal consumption and BMI over 8 years differ by weight status in a sample of adolescents.

DESIGN

Longitudinal, population-based study. Breakfast, lunch and dinner consumption and BMI were self-reported. Linear regressions were used to examine how the associations between meal consumption and BMI differed by weight status.

SETTING

Adolescents in the Minneapolis/St. Paul metropolitan area.

PARTICIPANTS

Adolescents (n 1,471) were surveyed as part of the EAT 2010-2018 in 2009-2010 (Mage = 14·3 years) and 2017-2018 (Mage = 22·0 years).

RESULTS

The prevalence of regular breakfast, lunch and dinner consumption (≥ 5 times/week) ranged from 45 to 65 %, 75 to 89 % and 76 to 94 %, respectively, depending on weight status category. Among adolescents with a sex- and age-specific BMI < 15th percentile, regular consumptions of breakfast, lunch and dinner during adolescence were positively associated with BMI in emerging adulthood compared with irregular consumption of breakfast, lunch and dinner (<5 times/week) after adjustment for socio-demographic characteristics (β = 5·43, β = 5·39 and β = 6·46, respectively; all P-values <0·01). Among adolescents in the BMI 15-85th and 85-95th percentiles, regular consumptions of breakfast, lunch and dinner were positively associated with BMI but to a lesser extent (P-values <0·01). For participants with a BMI ≥ 95th percentile, regular consumptions of breakfast, lunch and dinner were positively associated with BMI, but the associations were not statistically significant (P-values > 0·05).

CONCLUSIONS

The relationship between meal consumption during adolescence and BMI in emerging adulthood differs by adolescent weight status. Future studies should investigate underlying factors related to meal consumption routines and BMI.

Leveraging ecological momentary assessment to understand variability in food parenting practices within a low-income racially/ethnically diverse sample of parents of preschoolers

Children's eating behaviors are shaped significantly by their home food environment, including exposure to food parenting practices. The current study leveraged ecological momentary assessment (EMA) to describe how food parenting practices used to feed preschoolers (n = 116) differed across contextual factors around eating, including type of eating occasion (i.e., meals vs. snacks), day of the week (i.e., weekend vs. weekday), who initiated the meal (parent vs. child), emotional climate of the eating occasion. Parent perceptions of how well the eating occasion went, including how well the child ate and whether the food parenting practices worked as intended were also explored. Parent use of specific food parenting practices, situated within four higher-order domains (i.e., structure, autonomy support, coercive control, indulgent), was found to differ by type of eating occasion; parents engaged in a higher proportion of structure practices at meals than at snacks. Use of specific food parenting practices differed by mealtime emotional climate; parent use of structure and autonomy support was associated with eating occasions described as relaxed, enjoyable, neutral, and fun. Finally, parent perception of how well the child ate differed by use of specific food parenting practices; during eating occasions when parent's felt their child ate "not enough", they used less autonomy support and more coercive control compared to eating occasions where the child ate "enough and a good balance." Leveraging EMA allowed for increased understanding of the variability in food parenting practices and contextual factors. Findings may be utilized to inform the development of larger-scale studies seeking to understand why parents choose specific approaches to feeding their children, as well as the impact of various approaches to child feeding on child health outcomes.

Can Family and Parenting Factors Modify the Impact of Weight Stigma on Disordered Eating in Young People? A Population-Based Longitudinal Study

PURPOSE

Weight stigma is a prevalent problem in adolescents and a risk factor for disordered eating behaviors (DEBs). This study examined whether positive family/parenting factors were protective for DEBs among an ethnically/racially and socioeconomically diverse sample of adolescents with and without weight stigmatizing experiences.

METHODS

In Project Eating and Activity over Time (EAT) 2010-2018, 1,568 adolescents (mean age = 14.4 ± 2.0 years) were surveyed and followed into young adulthood (mean age = 22.2 ± 2.0 years). Modified Poisson regression models examined the relationships between three weight-stigmatizing experiences and four DEBs (e.g., overeating and binge eating) in models adjusted for sociodemographic characteristics and weight status. Interaction terms and stratified models examined whether family/parenting factors were protective for DEBs based on weight stigma status.

RESULTS

Higher family functioning and support for psychological autonomy were cross sectionally protective for DEBs. However, this pattern was primarily observed in adolescents who did not experience weight stigma. For example, among adolescents who did not experience peer weight teasing, high support for psychological autonomy was associated with lower prevalence of overeating (high support: 7.0%, low support: 12.5%, p = .003). Whereas, in participants who experienced family weight teasing, the difference in prevalence of overeating based on support for psychological autonomy was not statistically significant (high support: 17.9%, low support: 22.4%, p = .260).

DISCUSSION

General positive family and parenting factors did not entirely offset the effects of weight-stigmatizing experiences on DEBs, which may reflect the strength of weight stigma as a risk factor for DEBs. Future research is needed to identify effective strategies family members can use to support youth who experience weight stigma.

Implications of the COVID-19 Pandemic for the Well-Being of Emerging Adult Populations: A Synthesis of Findings From the COVID-19 Eating and Activity Over Time (C-EAT) Study

Research addressing the impact of the COVID-19 pandemic on psychosocial well-being and health behavior is accumulating; however, implications for emerging adult populations are underexplored. This manuscript synthesizes findings from a mixed-methods study of well-being, eating and activity behaviors, and food insecurity among a diverse, longitudinal cohort of emerging adults. The review includes findings from 11 original studies that involved collecting online surveys from 720 emerging adults and in-depth, virtual interviews with 33 respondents who were food insecure. Findings indicated the pandemic had widespread impacts on well-being. Population groups at greatest risk for poor outcomes included women; those who identified as Black, Indigenous, or a Person of Color; persons in households of low socioeconomic status; parents of young children; and persons who previously experienced mental health challenges or weight stigma. Further research will be needed to evaluate efforts to improve the well-being of emerging adults in the aftermath of the pandemic.

Weight-related Self-monitoring App Use Among Emerging Adults is Cross-sectionally Associated With Amount and Type of Physical Activity and Screen Time

Weight-related self-monitoring (WRSM) apps are often used by emerging adults to assist in behavior change. However, little is known about the relationship between WRSM among the general population of emerging adults and various physical activity and screen time behaviors. This paper examines associations between WRSM app use and various forms of physical activity and screen time among a population-based sample of emerging adults. Data come from EAT 2018 (N = 1,568, mean age = 22.0 ± 2.0 years), a population-based sample of emerging adults from Minneapolis/St. Paul, Minnesota. Participants reported on the types of WRSM apps used (physical activity and/or dietary focused), in addition to how much time they spent doing physical activity, whether they practiced yoga, compulsive exercise, recreational screen time, social media use, and whether they viewed dieting/weight loss materials. Linear and logistic regressions were used to assess adjusted means and prevalences of outcomes. We found that physical activity-focused WRSM app users engaged in more hours of total (8.7 vs 7.2, P < .001), and moderate-to-vigorous (5.1 vs 4.3, P = .002) physical activity compared to non-users. Similar results were found for dietary WRSM app users compared to non-users. However, WRSM app users had higher levels of compulsive exercise and were more likely to view dieting/weight loss materials (Ps < .001). Findings suggest that although physical activity is higher among WRSM users, the types of physical activity and screen time behaviors WRSM users are engaging in may be harmful.

Like parent, like child? Intuitive eating among emerging adults and their parents

Intuitive eating (IE) emphasizes relying on hunger and satiety cues to guide eating, and is associated with positive mental health and health-promoting behaviors. Although parents' own eating patterns often shape those of their children, no known research has explored familial associations of IE. The purpose of this cross-sectional, population-based study was to examine IE concordance between emerging adults and their parents, and whether concordance differed across sociodemographic characteristics and weight perceptions. The analytic sample included 891 emerging adults (M age = 22.0) and their primary parent (M age = 50.4) who participated in the population-based, longitudinal EAT and F-EAT 2010-2018 studies. Parents and emerging adults were grouped into dyads based on IE concordance: (1) neither are intuitive eaters; (2) only the emerging adult is an intuitive eater; (3) only the parent is an intuitive eater; (4) both are intuitive eaters. Dyads differed across socioeconomic status (SES), race/ethnicity, and weight perceptions. Concordant dyads who ate intuitively were more likely to be at higher SES and perceive their weight as "about right" than concordant dyads who did not eat intuitively. Asian emerging adults were most likely to belong to concordant non-intuitive eater dyads. Emerging adults who shared their parent's perception their weight was "overweight" were less likely to be intuitive eaters (even if their parents were). In this sample, sociodemographic characteristics and weight perceptions were related to IE concordance among emerging adults and their parents. Lower SES might be an intergenerational barrier to IE disproportionately impacting communities of color, though longitudinal data are needed. Results also suggest rather than motivating healthful eating, perceiving one's weight as "overweight" could hinder IE. Differences across sociodemographic variables likely intersect in meaningful ways, which is an important future research direction.

Efficacy of Eat Breathe Thrive: A randomized controlled trial of a yoga-based program

Evidence positions yoga as a promising intervention for enhancing positive embodiment and supporting the prevention of, and recovery from, eating disorders (EDs) by reducing ED symptomatology and building skills that facilitate an ongoing, embodied sense of wellbeing. However, yoga-based programs are few and rigorous literature on their efficacy is limited. This study examined the efficacy and feasibility of a yoga-based program called Eat Breathe Thrive (EBT) which aims to prevent EDs and support embodiment. Participants (N = 168, 93.5 % women) from a community sample in the United States and United Kingdom, ages 18-65, were randomly allocated to a 2-h, 7-week EBT program or waitlist-control condition. Compared to controls, EBT participants experienced significant decreases in ED behaviors, depression, and difficulties regulating emotions. They reported significantly greater use of mindfulness skills, such as interoceptive awareness, mindful self-care, and mindful eating. After a single session, participants reported immediate improvement in their sense of well-being, indicating increased state positive embodiment. Most effects were sustained at 6-month follow-up. The majority of individuals attended most sessions. Self-reported treatment integrity was excellent. Directions for future research are proposed. Results support the efficacy and feasibility of an integrated yoga intervention that fosters positive ways of inhabiting the body.

Body Esteem Explains the Relationship Between Mindful Eating and Self-Compassion: a Mediation Analysis

Research illustrates that high levels of self-compassion are associated with individuals eating in a mindful way. Previous research focusing upon emotional eating behaviours has suggested that body esteem is a mechanism that links self-compassion to eating behaviours, whilst mindful eating relates negatively to emotional eating and displays another, more adaptive way of eating. The present research explored whether body esteem could explain (i.e. mediate) the relationship between mindful eating and self-compassion. Two hundred participants were recruited to participate in a cross-sectional study to investigate the relationship between mindful eating, self-compassion, and body esteem. The present study highlights a positive correlation between mindful eating and body esteem, with a mediation effect being observed for mindful eating on self-compassion via the appearance subscale of body esteem. Possible explanations and future directions are discussed further with an emphasis on the need for more empirical work. In addition, suggestions are provided regarding the inclusion of body esteem within weight management interventions focusing upon mindful eating and self-compassion.

Yoga at Every Size: A Preliminary Evaluation of a Brief Online Size-Inclusive Yoga and Body Gratitude Journaling Intervention to Enhance Positive Embodiment in Higher Weight College Women

The present pilot randomized controlled trial (RCT) evaluated the feasibility, acceptability, and preliminary efficacy of a 4-week online yoga and body gratitude journaling intervention for strengthening positive embodiment among racially-diverse higher weight college women. Seventy-five participants were initially randomized to either the yoga condition (n = 36) or to a wait-list control (n = 39). Participants completed measures of positive and negative body image, weight bias internalization, self-compassion, drive for leanness, and physical activity acceptance at both baseline and post. Preliminary results among the 42 analyzed completers (mean age = 20.9, SD = 2.4; 30% Black or African American) revealed acceptable feasibility given the low-intensity nature of the intervention reflected in a 36% attrition rate. Self-reported adherence was strong for the yoga component with 81% of participants indicating that they practiced with the videos ≥3–4 times per week as suggested. Although 71% reported completing the body gratitude journal ≥1–2 times per week, daily adherence was minimal. Acceptability was also high among participants randomized to the yoga condition as indicated by 86% expressing at least moderate levels of satisfaction with the overall program. Qualitative feedback from participants further supported the acceptability of the program and pointed to important areas in further refining the protocol in the future. Preliminary efficacy was supported by significant reductions in internal body shame and gains in body appreciation, functional body appreciation, functional body satisfaction, functional body awareness, and behavioral commitment to physical activity engagement among the yoga vs. wait-list control participants. These promising findings once replicated in larger, higher-powered trials may have important implications for extending the reach and accessibility of mind-body wellness practices like yoga to benefit racially-/ethnically-diverse college women of higher weight. This research is further responsive to the growing need for efficacious remotely-delivered, and scalable behavioral health interventions in the ongoing era of the COVID-19 pandemic. However, additional research is warranted to explore ways of enhancing engagement of participants with lower levels of positive embodiment and to further incentivize the journaling component of the intervention.

Body dissatisfaction and disordered eating are prevalent problems among U.S. young people from diverse socioeconomic backgrounds: Findings from the EAT 2010-2018 study

PURPOSE

Body dissatisfaction and disordered eating are linked to adverse health consequences. Research describing socioeconomic patterns in the prevalence of these problems is important for informing the design of health services and efforts to improve health equity.

METHODS

Population-based cohort study (EAT 2010-2018: Eating and Activity over Time) of socioeconomically and ethnically/racially diverse U.S. young people who completed surveys as adolescents in 2009-2010 (mean age = 14.5 years) and as emerging adults in 2018 (mean age = 22.0 years). Participants were recruited from 20 schools in Minneapolis-St. Paul, Minnesota. Household socioeconomic status was determined using adolescent report of parental education, employment, and public assistance benefits. Analyses were conducted using data from 1531 participants and regression models that accounted for repeated measures within individuals.

RESULTS

Among females, high body dissatisfaction and unhealthy weight control behaviors (e.g., skipping meals) were more prevalent and regular use of lifestyle weight management behaviors (e.g., exercise) was less prevalent in the low SES group as compared to the middle and/or upper SES groups (p ≤ .010). Among males, thinness-oriented dieting, unhealthy weight control behaviors, and extreme weight control behaviors (e.g., taking diet pills) were all more prevalent in the low SES group as compared to the middle and/or upper SES groups (p ≤ .010). Few differences were observed across SES groups in models that adjusted for ethnic/racial identity and body mass index.

CONCLUSIONS

There is a need for greater attention to the reach and relevance of efforts to prevent disordered eating and improve body satisfaction to ensure efforts benefit young people across SES groups.

Do emerging adults know what their friends are doing and does it really matter? Methodologic challenges and associations of perceived and actual friend behaviors with emerging adults' disordered eating and muscle building behaviors

Disordered eating and muscle building behaviors are common among emerging adults, and friends may be a particularly salient social influence. Epidemiologic research often includes questions about participants' perceptions of their friends. A less common approach, with greater logistical challenges, is to ask for friend nominations and then survey friends about their actual behaviors. The comparability of these different approaches is unknown. This study addresses the following research questions: 1) What is the feasibility of collecting data from emerging adults' friends in epidemiologic research? 2) Do perceptions of friends' weight- and shape-related behaviors align with friends' actual behaviors? and 3) Are perceptions or friends' actual behaviors more strongly and consistently associated with emerging adults' behaviors? Participants (N = 2383) in the EAT (Eating and Activity over Time)-2018 study in Minnesota, USA, were asked to nominate up to three friends and provide data about those friends' weight- and shape-related behaviors (i.e. perceptions); nominated friends were invited to complete an abbreviated survey and report on their own same behaviors (i.e. actual). Among the invited friends, 191 responded and were linked to the 152 EAT 2018 participants who nominated them. Descriptive statistics, Spearman's correlations, and logistic regression were used to address the research questions. The response rate for nominated friends was very low (9.9%), suggesting this approach may have low feasibility for epidemiologic studies of emerging adults. Emerging adults' perceptions of their nominated friends' weight and shape-related behaviors generally did not align well with the behaviors reported by those friends. Furthermore, analytic models found different associations between friends' behavior and EAT 2018 participant behaviors, depending on the measure of friends' behavior used (perceived or actual). Careful consideration of the pros and cons of each study design is essential to build an evidence base and support interventions regarding emerging adults' weight- and shape-related health.

Disordered eating in a population-based sample of young adults during the COVID-19 outbreak

OBJECTIVE

The present study aimed to describe the experience of, and factors associated with, disordered eating in a population-based sample of emerging adults during the COVID-19 outbreak.

METHOD

Participants in the EAT 2010-2018 (Eating and Activity over Time) study were invited to complete the C-EAT (COVID-19 EAT) survey in April-May 2020. There were 720 respondents to the survey (age: 24.7 ± 2.0 years). Psychological distress, stress, stress management, financial difficulties, and food insecurity during the COVID-19 pandemic were examined as cross-sectional correlates of disordered eating in 2020. Open-ended questions assessed the perceived impact of the pandemic on eating behaviors.

RESULTS

Low stress management was significantly associated with a higher count of extreme unhealthy weight control behaviors (UWCBs). Food insecurity, higher depressive symptoms, and financial difficulties were significantly associated with a higher count of less extreme UWCBs. Higher stress and depressive symptoms were significantly associated with greater odds of binge eating. Six themes pertaining to disordered eating during the pandemic emerged: (a) mindless eating and snacking; (b) increased food consumption; (c) generalized decrease in appetite or dietary intake; (d) eating to cope; (e) pandemic-related reductions in dietary intake; and (f) re-emergence or marked increase in eating disorder symptoms.

DISCUSSION

Psychological distress, stress management, financial difficulties, and abrupt schedule changes may have contributed to disordered eating during the COVID-19 pandemic. Interventions that target stress management, depressive symptoms, and financial strain and provide tools to develop a routine may be particularly effective for emerging adults at risk of developing disordered eating during public health crises.

Recreational Screen Time Behaviors during the COVID-19 Pandemic in the U.S.: A Mixed-Methods Study among a Diverse Population-Based Sample of Emerging Adults

Understanding how screen time behaviors changed during the COVID-19 pandemic is important to inform the design of health promotion interventions. The purpose of this study was to quantify and describe changes in recreational screen time from 2018 to 2020 among a diverse sample of emerging adults. Participants (n = 716) reported their average weekly recreational screen time in 2018 and again during the pandemic in 2020. Additionally, participants qualitatively reported how events related to COVID-19 had influenced their screen time. Weekly recreational screen time increased from 25.9 ± 11.9 h in 2018 to 28.5 ± 11.6 h during COVID-19 (p < 0.001). The form of screen time most commonly reported to increase was TV shows and streaming services (n = 233). Commonly reported reasons for changes in screen time were boredom (n = 112) and a desire to connect with others (n = 52). Some participants reported trying to reduce screen time because of its negative impact on their mental health (n = 32). Findings suggest that screen time and mental health may be intertwined during the pandemic as it may lead to poorer mental health for some, while promoting connectedness for others. Health professionals and public health messaging could promote specific forms for screen time to encourage social connection during the COVID-19 pandemic and beyond.

Changes to Physical Activity during a Global Pandemic: A Mixed Methods Analysis among a Diverse Population-Based Sample of Emerging Adults in the U.S

Emerging adults' lives have changed because of the COVID-19 pandemic. Physical activity (PA) behaviors need to be examined to inform interventions and improve health. Responses to the C-EAT (COVID-19 Eating and Activity over Time) survey (N = 720; age = 24.7 ± 2.0 yrs) were analyzed. This mixed-methods study quantitatively examined changes in self-reported PA (hours/week of mild PA, moderate-to-vigorous PA (MVPA), and total PA) from 2018 to 2020. Qualitative responses on how COVID-19 impacted PA were analyzed using a grounded theory approach. Hours of PA were lower on average for all intensity levels during COVID-19 than in 2018 (p's < 0.0001). Over half of the sample reported a decrease in MVPA (53.8%) and total PA (55.6%); 42.6% reported a decrease in mild PA. High SES were more likely to report an increase in total PA (p = 0.001) compared to those of lower SES. Most (83.6%) participants perceived that COVID-19 had influenced their PA. The most common explanations were decreased gym access, effects on outdoor PA, and increased dependence on at-home PA. Results suggest that emerging adults would benefit from behavioral interventions and health promotion efforts in response to the pandemic, with a focus on activities that can be easily performed in the home or in safe neighborhood spaces.
