Examining measurement invariance of appetitive trait and ARFID symptom measures by food security status

OBJECTIVE

Measures assessing appetitive traits (i.e., individual differences in the desire to consume food) and disordered eating have generally been developed in predominantly food-secure populations. The current study aims to test measurement invariance (MI) for a measure of appetitive traits and a measure of Avoidant Restrictive Food Intake Disorder (ARFID) symptomology across food security status.

METHOD

Data from a sample of mothers (n = 634) and two undergraduate samples (n = 945 and n = 442) were used to assess MI for the Adult Eating Behavior Questionnaire (AEBQ), which measures appetitive traits, and the Nine Item ARFID Screen (NIAS), which measures ARFID symptomology. Current food security was assessed using the 18-item USDA Household Food Security Survey Module, which was dichotomized into two groups: 1) the 'food insecure' group included marginal, low, and very low food security and 2) the 'food secure' group included high food security. Overall and multi-group confirmatory factor analyses were conducted separately for each measure in each sample.

RESULTS

Results demonstrated scalar (i.e., strong) MI for both measures across samples, indicating that these measures performed equivalently across food-secure and food-insecure individuals.

CONCLUSION

Findings suggest that differences in appetitive traits by food security status observed in prior research are not artifacts of measurement differences, but instead reflect true differences. Additionally, past mixed results regarding the relationship between food insecurity (FI) and ARFID symptomology are not likely driven by measurement error when using the NIAS.

Cross-sectional and longitudinal associations between higher weight and eating disorder risk among collegiate athletes

OBJECTIVES

To examine whether higher weight status is associated with increased eating disorder risk in athletes.

DESIGN

Study 1 used cross-sectional (N = 942) and longitudinal (N = 483) data collected over a five-year period from Division I athletes at a Midwestern university. Study 2 used cross-sectional data from athletes competing at various levels at universities across the United States (N = 825).

METHODS

Weight and height were measured in Study 1 and self-reported in Study 2; higher weight was defined as body mass index ≥ 25 kg/m2. Eating disorder risk was assessed with preliminary (Study 1) and final (Study 2) versions of the Eating Disorders Screen for Athletes. Study 1 examined weight status in relation to both concurrent and one-year changes in Eating Disorder Screen for Athletes score. Study 2 examined weight status in relation to both the Eating Disorders Screen for Athletes score and elevated eating disorder risk using the established Eating Disorders Screen for Athletes cut-off. All models adjusted for gender and sport type; Study 2 additionally adjusted for race/ethnicity, age, and competition level.

RESULTS

Across studies, higher weight status was significantly associated with increased eating disorder risk among athletes. This association was observed both cross-sectionally and longitudinally, and the prevelence of elevated eating disorder risk was 43 % greater among athletes with higher weight status than among those without higher weight status.

CONCLUSIONS

Despite existing stereotypes that eating disorders tend to occur with low weight status, findings highlight the importance of screening all athletes for eating disorders, regardless of their weight status.

Associations between parental engagement in disordered eating behaviors and use of specific food parenting practices within a racially, ethnically, and socioeconomically diverse sample

Parents influence their children's eating behaviors through their use of food parenting practices, or goal-directed behaviors that guide both what and how they feed their child. Prior research suggests that parents who engage in disordered eating behaviors are more likely to use coercive food parenting practices, which are known to be associated with the development of maladaptive eating behaviors in young people. The present study sought to extend our current understanding by examining the association between parental engagement in disordered eating behaviors and use of a broader range of food parenting practices in a socioeconomically and racially diverse, population-based sample (n = 1306 parents/child dyads). Parents self-reported their disordered eating behaviors, as well as use of coercive and structure-based food parenting practices. A series of separate linear regression models, adjusting for parent and child sociodemographic and anthropometric characteristics, revealed that parents engaging in restrictive disordered eating behaviors and binge eating reported significantly higher levels of coercive food parenting practices, including pressure-to-eat, restriction, threats and bribes, and using food to control negative emotions. Parental engagement in restrictive disordered eating behaviors was also associated with significantly higher use of food rules and limits. Overall, parental engagement in compensatory disordered eating behaviors was significantly associated with higher levels of restrictive and emotional feeding practices, as well as with lower levels of monitoring. Given prior research supporting a relationship between exposure to coercive control food parenting practices and the development of maladaptive eating behaviors in young people, results from the current study provide support for the role that food parenting practices might play in the intergenerational transmission of disordered eating behaviors.

Reported Intergenerational Transmission of Parent Weight Talk and Links with Child Health and Wellbeing

OBJECTIVES

To examine if intergenerational transmission of parent weight talk occurs, the contextual factors prompting weight talk, and whether parent weight talk is associated with child weight, dietary intake, psychosocial outcomes, and food parenting practices.

STUDY DESIGN

Children aged 5-9 years and their families (n = 1307) from 6 racial and ethnic groups (African-American, Hispanic, Hmong, Native American, Somali/Ethiopian, White) were recruited for a longitudinal cohort study through primary care clinics in Minneapolis/St. Paul, Minnesota from 2016 through 2019. Parents filled out surveys at 2 time points, 18 months apart. Adjusted regression models examined associations of interest.

RESULTS

Intergenerational transmission of parent weight talk was observed. In addition, significant associations were found between parent engagement in weight talk and higher weight status and poorer psychosocial outcomes in children 18 months later. Parent engagement in weight talk was also associated with more restrictive food parenting practices 18 months later.

CONCLUSIONS

Parents' exposure to weight talk as children increased the likelihood of engaging in weight talk with their own children and had harmful associations over time with parent restrictive feeding practices, child weight, and psychosocial wellbeing in children. Health care providers may want to consider both modeling positive health-focused conversations and educating parents about the potential harmful and long-lasting consequences of engaging in weight talk with their children.

Past-Year Suicidal Ideation, Plans, and Attempts by Food Security Level in a Nationally Representative Sample of U.S. Adults

OBJECTIVE

The Interpersonal Theory of Suicide posits that suicidal behavior results from thwarted belongingness, perceived burdensomeness, and capability for suicide. Considering that food insecurity (FI) may be linked to these constructs to differing extents based on severity of FI, this study examined cross-sectional associations between levels of FI and suicidal ideation, plans, and attempts in a nationally representative sample of adults in the United States.

METHODS

Data for this study were collected in 2001-2003 from 5,552 participants in the National Comorbidity Survey Replication (Mage=44.8 ± 0.5 years; 53.8% female). Prevalence ratios (PRs) and 95% confidence intervals (CIs) were generated using modified Poisson regression to examine past-year ideation, plans, and attempts with intent of lethality by past-year FI level (assessed with a modified version of the Short Form U.S. Household Food Security Scale).

RESULTS

After controlling for sociodemographic covariates, low food security was significantly associated with elevated prevalence of suicidal ideation, plans, and attempts (ideation: PR = 2.21, 95% CI 1.32-3.70; plans: PR = 5.42, 95% CI 2.71-10.83; attempts: PR = 5.35, 95% CI 2.38-12.03). Very low food security (i.e., more severe FI) exhibited stronger associations yet with suicidal ideation, plans, and attempts (ideation: PR = 6.99, 95% CI 4.10-11.92; plans: PR = 17.21, 95% CI 8.41-35.24; attempts: PR = 14.72, 95% CI 4.96-43.69).

CONCLUSIONS

Findings indicative of a dose-response relationship between FI and suicidal ideation, plans, and attempts emphasize the need to increase reach of food assistance programs, increase availability of mental health services in food-insecure populations, and routinely screen for FI in mental health practice.

How Parental Feeding Practices Relate to Young People's Intuitive Eating: Cross-Sectional and Longitudinal Associations by Gender and Weight Concern

PURPOSE

To evaluate cross-sectional and longitudinal associations between controlling parental feeding practices in adolescence (i.e., restrictive feeding and pressure-to-eat [PE]) and intuitive eating (IE) in adolescence and emerging adulthood; and explore child gender and parental concern about child weight as moderators.

METHODS

The sample included participants (N = 1,383) from the population-based EAT 2010-2018 study who provided data in adolescence (14.4 ± 2.0 years) and emerging adulthood (22.0 ± 2.0 years) and had at least one caregiver complete surveys in adolescence. Generalized estimating equations evaluated cross-sectional and longitudinal associations between restrictive feeding and PE in adolescence and IE in adolescence and emerging adulthood. Interactions with gender and parental concern over child weight in adolescence were explored.

RESULTS

Restrictive feeding was cross-sectionally associated with lower IE in adolescence (b = -0.04), though evidence of moderation by parental weight concern indicated this association was only observed in the context of low parental weight concern. Greater PE was associated with lower adolescent IE among boys but higher IE among girls. Longitudinally, the association between PE in adolescence and IE in emerging adulthood differed by parental weight concern; greater PE predicted higher emerging adult IE at high parental weight concern, but lower IE at low parental weight concern.

DISCUSSION

Controlling feeding practices in adolescence displayed differential associations with child IE in adolescence and emerging adulthood based on child gender and parental concern over child weight. Notably, PE was associated with greater IE among adolescent girls but lower IE among boys. Results suggest that parental feeding is a valuable intervention target.

Adverse childhood experiences and food insecurity in emerging adulthood: findings from the EAT 2010-2018 study

OBJECTIVE

Low childhood socio-economic status (SES) and adverse childhood experiences (ACE) are associated with poor health outcomes in adulthood. Determining how ACE may be linked to food insecurity among young people from socio-economically diverse households can inform health-protective strategies. This study examined if ACE are associated with food insecurity during the transition to adulthood and investigated prevalence differences across SES strata.

SETTING

Participants were recruited from twenty secondary schools in Minneapolis-St. Paul, Minnesota.

PARTICIPANTS

The analytic sample (n 1518) completed classroom surveys in 2009-2010 (mean age = 14·5 years) and follow-up surveys in 2017-2018 (mean age = 22·0 years).

DESIGN

Past-year food insecurity was reported at both time points, and ACE were reported at follow-up. Logistic regression models were used to estimate emerging adult food insecurity prevalence by ACE exposure; models were stratified by childhood SES (low, middle and high).

RESULTS

The adjusted prevalence of food insecurity was 45·3 % among emerging adults who reported three or more ACE compared with 23·6 % among those with one or two ACE and 15·5 % among those with no ACE (P < 0·001). All forms of ACE were related to an elevated prevalence of food insecurity in emerging adulthood. ACE-food insecurity associations were strongest for emerging adults from lower and middle SES households. Among emerging adults from low SES households, childhood experiences of emotional abuse and substance use by a household member were associated with the largest prevalence differences in food insecurity.

CONCLUSIONS

Findings suggest a need for trauma-informed services within food assistance programs to better serve individuals with a history of ACE.

Longitudinal associations between family meal quality and quantity: Does one matter more for child, parent, and family health and well-being or are they synergistic?

It is unknown how family meal quantity (i.e., frequency) and quality (i.e., meal healthfulness and interpersonal quality) are associated with child, parent, and family health and well-being over time. This study aimed to examine longitudinal associations between family meal quantity and quality and child, parent, and family health and well-being and whether there was a synergistic effect between family meal quantity and quality. Children ages 5-9 and their parents from six racial/ethnic groups participated in this longitudinal cohort study. Regression models adjusted for socio-demographic characteristics examined family meal quantity, interpersonal quality, and nutritional quality at baseline and interactions between quantity and quality, in relation to changes in child, parent, and family health outcomes from baseline to 18-month follow-up. Higher family meal quantity predicted reduced obesity prevalence, improved diet quality and less food fussiness, food responsiveness, and conduct problems among children at follow-up. Higher family meal quality predicted improved diet quality, lower emotional problems, less food responsiveness, and fewer peer relationship problems among children, improved diet quality and reduced psychological distress for parents, and less family chaos at follow-up. One interaction between family meal quantity and quality was found for child peer relationship problems. Overall, family meal quantity and quality were independently important for child health and well-being and for some parent and family health outcomes. Clinicians working with families may want to emphasize the importance of both family meal quantity and quality, as these longitudinal findings suggest potential benefits for the entire family.

More Than Identity: An Intersectional Approach to Understanding Mental-Emotional Well-Being of Emerging Adults by Centering Lived Experiences of Marginalization

Understanding social determinants that shape pertinent developmental shifts during emerging adulthood (i.e., ages 18-25 years) and their associations with psychological health requires a nuanced approach. In our exploratory study, we investigated how multiple social identities and lived experiences generated by systems of marginalization and power (e.g., racism, classism, sexism) intersect in connection to the mental-emotional well-being of emerging adults (EAs). Eating and Activity Over Time (EAT, 2010-2018) data were collected from 1,568 EAs (mean age = 22.2 (standard deviation, 2.0) years) recruited initially in 2010 from Minneapolis/St. Paul schools. Conditional inference tree analyses were employed to treat "social location" and systems of marginalization and power as interdependent social factors influencing EAs' mental-emotional well-being outcomes: depressive symptoms, stress, self-esteem, and self-compassion. Conditional inference tree analyses identified EAs' subgroups with differing mean levels of mental-emotional well-being outcomes, distinguished primarily by marginalized social experiences (e.g., discrimination, financial difficulties) rather than social identities themselves. The relative positioning of EAs' experiences of social marginalization (e.g., discrimination) to their social identities (e.g., race/ethnicity) suggests that the social experiences generated by systems of privilege and oppression (e.g., racism) are more adjacent social determinants of mental-emotional well-being than the social identities used in public health research to proxy the oppressive systems that give them social meaning.

The interplay between food insecurity and family factors in relation to disordered eating in adolescence

This study examined the association between food insecurity and both binge eating and unhealthy weight-control behaviors (UWCBs) and assessed whether such associations differ by factors within the family environment. Data were collected from a diverse sample of adolescents (Mage = 14.5 years; 54.1% female) and their parents/guardians (N = 2137 dyads) participating in EAT 2010 (Eating and Activity over Time). Food-insecure adolescents were more likely to report binge eating (prevalence ratio [PR] = 1.94; 95% confidence interval [CI]: 1.41-2.69) and UWCBs (PR = 1.34; 95% CI: 1.21-1.49) than food-secure adolescents. Family meal importance (p = .03) and family communication (p < .001) significantly moderated the association between food insecurity and UWCBs, such that the association was weaker at lower levels of these factors. Significant interactions with parental weight talk/concern (p < .001) and weight teasing (p = .04) indicated a weaker association between food insecurity and UWCBs in the presence of these factors. Findings indicate that the association between food insecurity and UWCBs among youth is less salient in the absence of family protective factors and in the presence of family risk factors for UWCBs, indicating the importance of targeting food insecurity itself, regardless of the presence of family risk or protective factors for UWCBs.

Is intuitive eating a privileged approach? Cross-sectional and longitudinal associations between food insecurity and intuitive eating

OBJECTIVE

To examine: (1) cross-sectional and longitudinal associations between measures of food insecurity (FI; household status and youth-reported) and intuitive eating (IE) from adolescence to emerging adulthood; and (2) the association between FI persistence and IE in emerging adulthood.

DESIGN

Longitudinal population-based study. Young people reported IE and FI (two items from the US Household Food Security Module) in adolescence and emerging adulthood. Parents provided data on household FI via the six-item US Household Food Security Module in adolescence.

SETTING

Adolescents (Mage = 14·3 ± 2 years) and their parents, recruited from Minneapolis/St. Paul public schools in 2009-2010 and again in 2017-2018 as emerging adults (Mage = 22·1 ± 2 years).

PARTICIPANTS

The analytic sample (n 1372; 53·1 % female, 46·9 % male) was diverse across race/ethnicity (19·8 % Asian, 28·5 % Black, 16·6 % Latinx, 14·7 % Multiracial/Other and 19·9 % White) and socio-economic status (58·6 % low/lower middle, 16·8 % middle and 21·0 % upper middle/high).

RESULTS

In cross-sectional analyses, youth-reported FI was associated with lower IE during adolescence (P = 0·02) and emerging adulthood (P < 0·001). Longitudinally, household FI, but not adolescent experience of FI, was associated with lower IE in emerging adulthood (P = 0·01). Those who remained food-insecure (P = 0·05) or became food-insecure (P = 0·02) had lower IE in emerging adulthood than those remaining food-secure. All effect sizes were small.

CONCLUSIONS

Results suggest FI may exert immediate and potentially lasting impacts on IE. As evidence suggests IE is an adaptive approach conferring benefits beyond eating, it would be valuable for interventions to address social and structural barriers that could impede IE.

Socioeconomic status and eating disorder prevalence: at the intersections of gender identity, sexual orientation, and race/ethnicity

BACKGROUND

Longstanding biases have fostered the erroneous notion that only those of higher socioeconomic status (SES) experience eating disorders (EDs); however, EDs present across all SES strata. Considering the dearth of ED research among those of lower SES, this study examined (1) the overall association between SES and ED prevalence, and (2) ED prevalence in the context of four relevant social identities (i.e. SES, gender identity, sexual orientation, and race/ethnicity) from an intersectional perspective, as unique combinations of multiple social identities may differentially influence risk.

METHODS

A sample of 120 891 undergraduate/graduate students from the Healthy Minds Study self-reported family SES with a single-item question, gender identity, sexual orientation, and race/ethnicity, and were screened for ED risk.

RESULTS

Participants of lower SES had 1.27 (95% CI 1.25-1.30) times greater prevalence of a positive ED screen than those of higher SES. Substantial heterogeneity was observed across the four social identities beyond the association with SES. For example, positive ED screens were particularly common among lower SES, Latinx, sexual minority cisgender men and women, with 52% of bisexual men and 52% of lesbian women of Latinx ethnicity and lower SES screening positive.

CONCLUSIONS

Although positive ED screens were more common among undergraduate/graduate students of lower SES, the particularly high ED risk reported by certain groups of lower SES with multiple minority identities reinforces the importance of investigating multi-layered constructs of identity when identifying groups at disproportionate risk.

Do the SCOFF items function differently by food-security status in U.S. college students?: Statistically, but not practically, significant differences

Despite food insecurity (FI) being associated with eating disorders (EDs), little research has examined if ED screening measures perform differently in individuals with FI. This study tested whether items on the SCOFF performed differently as a function of FI. As many people with FI hold multiple marginalized identities, this study also tested if the SCOFF performs differently as a function of food-security status in individuals with different gender identities and different perceived weight statuses. Data were from the 2020/2021 Healthy Minds Study (N = 122,269). Past-year FI was established using the two-item Hunger Vital Sign. Differential item functioning (DIF) assessed whether SCOFF items performed differently (i.e., had different probabilities of endorsement) in groups of individuals with FI versus those without. Both uniform DIF (constant between-group difference in item-endorsement probability across ED pathology) and non-uniform DIF (variable between-group difference in item-endorsement probability across ED pathology) were examined. Several SCOFF items demonstrated both statistically significant uniform and non-uniform DIF (ps < .001), but no instances of DIF reached practical significance (as indicated by effect sizes pseudo ΔR2 ≥ 0.035; all pseudo ΔR2's ≤ 0.006). When stratifying by gender identity and weight status, although most items demonstrated statistically significant DIF, only the SCOFF item measuring body-size perception showed practically significant non-uniform DIF for perceived weight status. Findings suggest the SCOFF is an appropriate screening measure for ED pathology among college students with FI and provide preliminary support for using the SCOFF in individuals with FI and certain marginalized identities.

Exploring differences in disordered eating and related appetitive traits among women based on childhood and current food security status

Despite emerging evidence that food insecurity (FI) is associated with elevated rates of eating pathology, little is known about the lasting impact of FI on eating behaviors. Studies that have explored the association between FI during childhood and eating behavior in adulthood have not accounted for current FI. The present study explored differences in disordered eating (DE) and related appetitive traits among four groups of cisgender female mothers: individuals who (1) endorsed childhood FI only (n = 96), (2) endorsed current FI only (n = 134), (3) endorsed both childhood and current FI (n = 257), and (4) denied both childhood and current FI (n = 146). Participants responded to online questionnaires including items from the USDA Household Food Security Survey Module, the 7-item Eating Disorder Examination-Questionnaire, the Eating Disorder Diagnostic Scale, and the Adult Eating Behavior Questionnaire. Adjusting for age and race/ethnicity, ANCOVAs explored mean differences between groups in DE and appetitive traits, and a modified Poisson regression model examined differences in binge-eating prevalence across the four FI groups. The "current FI only" group consistently endorsed the highest levels of DE and related appetitive traits followed by the "current and childhood FI" group, suggesting newly food-insecure women may be at highest risk for DE. Interestingly, across almost all constructs, the "childhood FI only" group did not differ significantly from the "no FI" group. These findings suggest that improved access to food may help offset risk for adult DE related to experiences of FI in childhood.

Household food insecurity is associated with greater prevalence and 18-month incidence of a range of disordered eating behaviors in a racially and ethnically diverse sample of parents

This study examined cross-sectional and longitudinal associations between household food insecurity (FI) and a range of disordered eating behaviors (DEBs) and explored whether associations differ by Supplemental Nutrition Assistance Program (SNAP)/Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) participation. Data came from 1120 racially/ethnically diverse parents (Mage = 35.7 ± 7.8 years at baseline) in the Family Matters longitudinal cohort study. Parents reported on household FI and SNAP/WIC participation at baseline, and on past-year restrictive weight-control behaviors (WCBs; e.g., fasting), compensatory WCBs (e.g., self-induced vomiting), and binge eating at baseline and 18-month follow-up. Sociodemographics-adjusted modified Poisson regressions examined baseline household FI in relation to baseline prevalence and 18-month incidence (i.e., new onset) of each type of DEB. Moderation by SNAP/WIC participation was also tested. Household FI affected 29.6 % of participants and was associated with significantly greater baseline prevalence (prevalence ratios ranging from 1.38 to 2.69) and 18-month incidence (risk ratios ranging from 1.63 to 2.93) of each type of DEB examined. The association between household FI and incident compensatory WCBs differed significantly by SNAP/WIC participation, such that household FI significantly predicted new-onset compensatory WCBs at follow-up only among those participating in SNAP/WIC. Results from this study are the first, to our knowledge, to demonstrate that FI is longitudinally associated with restrictive and compensatory DEBs, thereby highlighting FI as a risk factor not only for binge eating, but for a range of DEBs. These findings emphasize the importance of screening for FI in clinical settings and the need to address structural barriers to food security.

Identifying transdiagnostically relevant risk and protective factors for internalizing psychopathology: An umbrella review of longitudinal meta-analyses

Internalizing mental disorders are highly comorbid with one another, and evidence suggests that etiological processes contributing to these disorders often overlap. This systematic umbrella review aimed to synthesize meta-analytic evidence from observational longitudinal studies to provide a comprehensive overview of potentially modifiable risk and protective factors across the depressive, anxiety, and eating disorder psychopathology domains. Six databases were searched from inception to August 2022. Only meta-analyses of longitudinal studies that accounted for baseline psychopathology (either via exclusion of baseline cases or statistical adjustment for baseline symptoms) were included. Methodological quality of meta-analyses was evaluated using the AMSTAR 2, and quality of evidence for each analysis was rated using GRADE. Study selection, quality assessment, and data extraction were conducted in duplicate by independent reviewers. The protocol for this review was registered with PROSPERO (CRD42020185575). Sixty-one meta-analyses were included, corresponding to 137 meta-analytic estimates for unique risk/protective factor-psychopathology relationships. Most potential risk/protective factors, however, were examined only in relation to depressive psychopathology. Concern over mistakes and self-esteem were the only risk and protective factors, respectively, identified as statistically significant across depressive, anxiety, and eating disorder psychopathology domains. Eight risk factors and four protective factors also emerged as having transdiagnostic relevance across depressive and anxiety domains. Results suggest intervention targets that may be valuable for preventing/treating the spectrum of internalizing psychopathology and reducing comorbidity. However, few factors were identified as transdiagnostically relevant across all three internalizing domains, highlighting the need for more research investigating similar sets of potential risk/protective factors across internalizing domains.

Relative food abundance predicts greater binge-eating symptoms in subsequent hours among young adults experiencing food insecurity: Support for the "feast-or-famine" cycle hypothesis from an ecological momentary assessment study

Food insecurity (FI) may increase risk for binge eating through a "feast-or-famine" cycle, where fluctuations in food availability correspond to alternating periods of food restriction and opportunities for binge eating, but research on this topic is limited. To clarify the relationship between food availability and binge eating in the context of FI, this study examined the association between momentary food security level and subsequent binge-eating symptoms among individuals in food-insecure households and investigated how this association differs by factors that may modify the extent to which food availability fluctuates. Ecological momentary assessment data were collected in 2020-2021 from 75 young adults (Mage = 25.3 ± 1.8 years; 72% female; 72% Black, Indigenous, or a Person of Color) in the United States who had experienced past-month household FI. For 14 days, participants reported four times per day on food security and eating episodes, and binge-eating symptoms were assessed for each reported eating episode. About 35% of the variance in momentary food security ratings was accounted for by within-person variability over time. A significant within-person association was observed in multilevel analyses, indicating that instances of greater food security relative to one's average level predicted greater subsequent binge-eating symptoms. Moderation analyses revealed that this association was significant only among individuals reporting use of food assistance programs, high engagement in resource trade-off coping strategies (e.g., skipping bill payments to buy food), or low food security-related self-efficacy. Overall, findings offer support for the "feast-or-famine" cycle hypothesis as an explanation for the link between FI and binge eating, emphasize the importance of identifying approaches to promote more stable access to adequate food, and suggest potential intervention targets to reduce risk for binge eating in populations experiencing FI.

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.

Participation in varsity sports, dance, and Greek life associated with menstrual disturbance in a national sample of female college students

Objective: The objective of this study was to identify university-sponsored activities associated with increased odds of menstrual disturbance among female college students. Participants: The sample included 3,277 female-identifying students at 12 colleges and universities participating in the Healthy Bodies Study during the 2013-2014 and 2014-2015 academic years. Methods: Crude and adjusted logistic regression models were run to report odds of any menstrual disturbance and amenorrhea (AMN) for participants in sports, dance, and Greek Life. Survey weights were used to account for response bias. Results: In the adjusted models, participation in varsity sport (OR = 1.82, CI 1.37, 2.37), dance (OR = 1.68, CI 1.37, 2.05) and Greek life (OR= 2.12, CI 0.13,0.18) was significantly associated with increased odds of menstrual disturbance, compared to non-participants. Conclusions: Findings suggest additional need for prevention and intervention programming against menstrual disturbance in varsity sports, dance, and Greek life activities.

Exploring the intersection of multiple social determinants of health and disordered eating behaviors in a population-based sample in the United States

OBJECTIVE

Disordered eating behaviors (DEBs) have long-term, deleterious effects on health and are more prevalent among socially marginalized groups, likely as a result of systemic inequities across social determinants of health (SDoH). This exploratory study aimed to identify subgroups of emerging adults characterized by main and interactive associations between SDoH and two forms of DEB (binge eating, extreme unhealthy weight control behaviors).

METHOD

Participants (n = 1568; age 22.2 ± 2.1 years) from the United States were drawn from the EAT 2010-2018 longitudinal study. Conditional inference tree (CIT) analyses derived main and intersecting SDoH related to DEB across 33 input variables collected during adolescence and emerging adulthood.

RESULTS

The binge eating CIT revealed five subgroups (prevalence: 6.3-23.2%) shaped by variables collected during emerging adulthood: appearance-based teasing (p < .001), financial difficulty (p = .003), gender (p < .001), and everyday discrimination (p = .008). The CIT results for extreme unhealthy weight control behaviors derived six subgroups (prevalence: 2.3-45.5%) shaped by weight teasing (p < .001) and gender (p < .001) during emerging adulthood and public assistance (p = .008) and neighborhood safety (p = .007) in adolescence.

DISCUSSION

This exploratory study revealed distinct subgroups of emerging adults with varying DEB prevalence, suggesting that variability in DEB prevalence may be partially explained by intersecting SDoH during adolescence and emerging adulthood. Hypothesis-driven research and replication studies are needed to further explore the associations between SDoH and DEB during emerging adulthood.

PUBLIC SIGNIFICANCE STATEMENT

Disordered eating behaviors are common among young people in the United States and have long-term health consequences. This exploratory study identified subgroups of young people, characterized by combinations of social inequities (e.g., financial difficulties, teasing). Results highlight high-risk subgroups of emerging adults that should be examined further in hypothesis-driven research.

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.

It Is Not What Happens to You But How You React to It That Matters: PTSD as a Moderator of the Association Between Trauma and Impulsive Behaviors

ABSTRACT

We examined the moderating role of posttraumatic stress disorder (PTSD) in the association between trauma and impulsive behaviors. Adult women ( N = 97) with a history of childhood sexual abuse (CSA; n = 26), rape in adulthood ( n = 21), both CSA and adult rape ( n = 25), or no history of sexual trauma ( n = 25) completed self-report questionnaires. PTSD symptoms were positively associated with self-harm and with stealing and accident proneness, but not with sexual impulsivity. Trauma group had no independent associations with impulsive behaviors. PTSD reexperiencing symptoms interacted with trauma group such that reexperiencing symptoms were positively associated with self-harm for the two trauma groups that included CSA but not for the control and adult rape-only groups. Overall, results indicate that PTSD symptoms-more so than the occurrence of trauma itself-associate with impulsive behavior. Results highlight the importance of assessing posttraumatic symptomatology, and not just trauma occurrence, when aiming to prevent or treat impulsive behaviors.

Past-Year Abuse and Eating Disorder Symptoms Among U.S. College Students

Evidence consistently indicates associations between eating disorders (EDs) and childhood emotional, physical, and sexual abuse, but the relationship between EDs and abuse occurring later in development has largely been unexplored. Therefore, the objective of this study was to examine associations between past-year abuse and ED symptoms among college students. Participants represented 12 U.S. colleges and universities participating in the Healthy Bodies Study (HBS) between 2013 and 2015 (N = 10,204; M_age = 23.38 years). Students self-reported experiences of emotional, physical, and sexual abuse over the past year. Cognitive ED symptoms (i.e., dietary restraint, shape/weight overvaluation, body dissatisfaction) were measured via the Short-Eating Disorder Examination-Questionnaire (S-EDE-Q), and behavioral ED symptoms (i.e., binge eating, purging) were measured via items from the full EDE-Q. Regression models that adjusted for demographics and weight status were conducted to examine associations between past-year abuse and ED symptoms. Past-year emotional, physical, and sexual abuse each exhibited independent associations with ED symptoms. When mutually adjusting for emotional, physical, and sexual abuse, past-year emotional abuse was associated with higher levels of dietary restraint (b = 0.20, p = .02), shape/weight overvaluation (b = 0.85, p < .001), body dissatisfaction (b = 0.63, p < .001), binge eating (prevalence ratio [PR] = 1.23, p = .002), and purging (PR = 1.68, p < .001), and past-year sexual abuse was associated with shape/weight overvaluation (b = 0.35, p = .03) and purging (PR = 1.71, p = .009) but no other ED symptoms. No associations were observed for past-year physical abuse in mutually adjusted models. In summary, past-year emotional abuse emerged as a key correlate of all ED symptoms examined in this sample of U.S. college students, while past-year sexual abuse also emerged as a key correlate of shape/weight overvaluation and purging. Findings emphasize the need to screen for abuse and implement abuse prevention efforts on college campuses.

Correlates of weight-related self-monitoring application use during emerging adulthood in a population-based sample

PURPOSE

This study was designed to examine (1) the types of technologies or other applications (apps) emerging adults use to track their eating, physical activity, or weight; (2) who uses these apps and (3) whether eating and weight-related concerns during adolescence predict app use in emerging adulthood.

METHODS

Longitudinal survey data were obtained from EAT 2010-2018 (Eating and Activity over Time study, N = 1428), a population-based sample of ethnically/racially and socioeconomically diverse adolescents (mean age: 14.5 ± 2.0 years), who were followed into emerging adulthood (mean age: 22.0 ± 2.0 years). Data were used to examine sociodemographic correlates of physical activity- and dietary-focused app use. Adjusted, gender-stratified logistic regressions were used to investigate longitudinal relationships between eating and weight-related concerns in adolescence and app use in emerging adulthood.

RESULTS

Compared to men, women were more likely to use physical activity- (23.2 versus 12.5%, p < 0.001) and dietary-focused apps (16.1 versus 5.5%, p < 0.001). Among women, eating and weight-related concerns in adolescence, particularly unhealthy muscle-building behaviors (OR = 1.73, 95% CI 1.03-2.92), were associated with later dietary-focused app use. Among men, use of other muscle-building behaviors and body dissatisfaction in adolescence predicted use of physical activity- (OR_{other muscle-building} = 1.60, 95% CI 1.03-2.49 and OR_{body dissatisfaction} = 1.67, 95% CI 1.06-2.65) and dietary-focused (OR_{other muscle-building} = 2.18, 95% CI 1.07-4.47 and OR_{body dissatisfaction} = 2.35, 95% CI 1.12-4.92) apps 8 years later.

CONCLUSIONS

Eating and weight-related concerns may predict later use of physical activity- and dietary-focused apps; future research is needed to understand whether use of such apps further increases eating and weight-related concerns.

Lifestyle health behavior correlates of intuitive eating in a population-based sample of men and women

The aim of this observational study was to examine how lifestyle health behaviors hypothesized to influence attunement to internal cues (breakfast consumption frequency, physical activity, yoga practice, sleep, and recreational screen time) are cross-sectionally related to intuitive eating (IE). Data from 765 men and 1009 women (M_age = 31.1 ± 1.7 years) who participated in Project EAT-IV (Eating and Activity in Teens and Young Adults) were analyzed with sex-stratified linear regression models adjusted for age, race/ethnicity, socioeconomic background, and parent status. Sociodemographic-adjusted mean levels of each health behavior by sex were generated at low (one standard deviation below the mean), average (at the mean), and high (one standard deviation above the mean) levels of IE to facilitate interpretation of regression results. Among women only, more frequent breakfast consumption (p = .02), more time spent practicing yoga (p = .03), more sleep (p = .004), and less recreational screen time (p = .01) were each significantly associated with higher IE after adjusting for sociodemographic characteristics. Compared to women with low IE, women with high IE reported, on average, eating breakfast 0.3 more days a week, practicing 12 more minutes of yoga per week, getting 12 more minutes of sleep per night, and engaging in 18 fewer minutes of recreational screen time per day. Results suggest that these modifiable health behaviors may be valuable targets for interventions to increase IE among women, though longitudinal research is needed to elucidate the temporality of these associations.

Attachment insecurity predicts worse outcome in patients with eating disorders treated with enhanced cognitive behavior therapy: A one-year follow-up study

OBJECTIVE

This study aimed to explore the role of attachment insecurity in predicting a worse longitudinal trend of eating disorder (ED) psychopathology and body uneasiness in patients with Anorexia Nervosa (AN) or Bulimia Nervosa (BN) treated with Enhanced Cognitive Behavior Therapy, considering the longitudinal interplay between these dimensions.

METHOD

In total, 185 patients with AN or BN performed the baseline assessment, and 123 were re-evaluated after 1 year of treatment. Participants completed questionnaires evaluating ED psychopathology (Eating Disorders Examination Questionnaire) and body uneasiness (body uneasiness test). For the assessment of adult attachment, the Experiences in Close Relationships-Revised was administered at baseline. Bivariate latent change score analysis within the structural equation modeling framework was performed to investigate the evolution of ED psychopathology and body uneasiness, their longitudinal interplay, and the role of attachment style as an outcome predictor.

RESULTS

After treatment, all psychopathological features showed an overall improvement. Higher baseline levels of body uneasiness predicted a worse course of ED psychopathology. The change in body uneasiness over time depended on changes over time in ED psychopathology, but not vice versa. Insecure attachment predicted a worse longitudinal trend of ED psychopathology, and, through this impairment, it indirectly maintained higher levels of body uneasiness, as confirmed by mediation analyses.

DISCUSSION

The role of attachment insecurity as a predictor of treatment outcome suggests the need for an integration of the cognitive-behavioral conceptualization of EDs with a developmental perspective that considers attachment-related issues.

PUBLIC SIGNIFICANCE STATEMENT

Considering the burden of EDs in terms of public health and the unsatisfactory response to standard treatments, the identification of outcome predictors is of considerable clinical interest. This study demonstrated that attachment insecurity was associated with worse longitudinal trends of ED psychopathology and body uneasiness in patients with AN and BN treated with CBT-E, highlighting the importance of personalizing treatment programs taking into account a developmental perspective on these disorders.

Does Weight-Motivation for Exercise Predict Physical Activity Levels Across the Life Course From Adolescence to Adulthood?

Healthcare professionals may motivate their patients to exercise to lose weight, but it is unknown how weight-focused motivations influence young peoples' PA trajectories.

PURPOSE

To examine if weight-motivated exercise predicts moderate-to-vigorous physical activity (MVPA) from adolescence to adulthood in a population-based sample and if this relationship differs by age and body mass index (BMI).

METHODS

Participants (N = 1,428; 13-18 years at baseline; 48.6% female; 49.0% white) responded to surveys in the 15-year longitudinal study, Project EAT (Eating and Activity in Teens and Young Adults). Weight-motivated exercise was examined as a predictor of MVPA across the life course at five-year intervals using linear regression generalized estimating equations and adjusting for demographics (age modeled continuously), BMI (modeled continuously), weight-related intentions, and prior MVPA.

RESULTS

Weight-motivated exercise predicted higher subsequent MVPA at five-year intervals among females (B = .57, 95% CI:0.13, 1.00) but not males (B = .31, 95% CI:-.09, .72). The association differed by BMI in females (p = .02); weight-motivated exercise was associated with higher subsequent MVPA at lower BMI but lower subsequent MVPA at higher BMI. The association also differed by age in males (p = .008), such that older males who reported weight-motivated exercise had higher subsequent MVPA, whereas this association was not present in younger males.

CONCLUSION

Weight-motivated exercise may have a deleterious influence on MVPA for females with higher BMI and may have an advantageous influence on older males. Understanding how motivations for exercise may influence PA trajectories can inform PA promotion over the life course by providing more nuanced guidance by age, BMI, and sex.

Food insecurity and its associations with bulimic-spectrum eating disorders, mood disorders, and anxiety disorders in a nationally representative sample of U.S. adults

PURPOSE

To examine cross-sectional associations between food insecurity and 12-month eating disorders, mood disorders, and anxiety disorders among U.S. adults.

METHODS

This study used data collected between 2001 and 2003 from 2914 participants in the National Comorbidity Survey-Replication, a nationally representative sample of U.S. adults (mean age = 44.9 years; 53.4% female). Twelve-month food insecurity was assessed with a modified version of the Short Form U.S. Household Food Security Scale. Twelve-month DSM-IV diagnoses of mental disorders were based on the World Health Organization Composite International Diagnostic Interview. Modified Poisson regression models were conducted, adjusting for age, sex, race/ethnicity, education, and income-to-poverty ratio.

RESULTS

Food insecurity was experienced by 11.1% of participants. Food insecurity was associated with greater prevalence of bulimic-spectrum eating disorders (prevalence ratio [PR] = 3.81; 95% confidence interval [CI] 2.26-6.42), mood disorders (PR = 2.53; 95% CI 1.96-3.29), and anxiety disorders (PR = 1.69; 95% CI 1.39-2.07).

CONCLUSION

Results indicate that food insecurity is associated with a range of internalizing mental disorders, though these findings should be confirmed with contemporary data to reflect DSM-5 diagnostic updates and the economic effects of the COVID-19 pandemic. Findings from this study emphasize the need to expand food insecurity interventions and improve access to mental health services for food-insecure populations.

Relationships Between Childhood Abuse and Eating Pathology Among Individuals with Binge-Eating Disorder: examining the Moderating Roles of Self-Discrepancy and Self-Directed Style

Childhood maltreatment appears to increase the risk for eating disorders (EDs). The current study examined potential moderating factors (i.e., self-discrepancy and negative self-directed style), which may increase or decrease the impact of maltreatment (i.e., emotional abuse, physical abuse, sexual abuse) on later ED symptoms. One hundred seven men and women with binge-eating disorder (BED) completed semi-structured interviews and questionnaires assessing childhood maltreatment, self-discrepancy, negative self-directed style, and ED pathology. Linear regression was used to examine the moderating role of self-discrepancy and negative self-directed style in the associations between each type of abuse and level of ED severity. Actual:ought self-discrepancy (i.e., the difference between one's self and who one believes they ought to be) moderated the relationships between ED pathology and emotional abuse (β =.26 p =.007), as well as physical abuse (β =.23, p =.02). Results suggest that the relationship between childhood abuse (i.e., emotional abuse, physical abuse) and ED pathology may be stronger for those with higher levels of actual:ought self-discrepancy. Further clarification of the relationships between actual:ought self-discrepancy and distinct forms of childhood abuse is needed, as well as intervention studies examining whether targeting actual:ought self-discrepancy provides an additional benefit for trauma-exposed individuals with BED.

Measurement invariance of body image measures by age, gender, sexual orientation, race, weight status, and age: The U.S. Body Project I

Despite growing interest in comparing body image experiences across diverse groups, limited work has examined whether body image measures operate similarly across different populations, raising important questions about the appropriateness of comparing scale means across demographic groups. This study employed measurement invariance testing to evaluate whether such comparisons are appropriate with existing body image measures. Specifically, multi-group confirmatory factor analysis was conducted using a community sample of 11,620 men and women to test increasing levels of invariance (configural, metric, scalar) across five key demographic variables (age group, gender, sexual orientation, race, weight status) for five commonly used body image measures (the Sociocultural Attitudes Towards Appearance Questionnaire-4, the Body Surveillance subscale of the Objectified Body Consciousness Scale, the Appearance Evaluation and Overweight Preoccupation subscales of the Multidimensional Body-Self Relations Questionnaire, and the Body Image Quality of Life Inventory). Results provided evidence of scalar (i.e., strong) invariance for all five measures across age, gender, sexual orientation, race, and weight status groups, indicating that the latent factors captured by these measures have the same meaning across demographic groups. Findings therefore support the comparison of scale/subscale means across multiple demographic groups for these body image measures.

Sexual orientation differences in pathways from sociocultural and objectification constructs to body satisfaction: The U.S. Body Project I

Objectification theory and the tripartite influence model provide useful frameworks for understanding the body image experiences of men and women. However, there is little systematic investigation of how sexual orientation moderates the links between these constructs and body image satisfaction. It has been hypothesized, for example, that the associations of surveillance (i.e., monitoring of one's appearance due to objectification by others) would be strongest for groups targeted by the male gaze (e.g., gay men, lesbian women, and bisexual men and women). Here we proposed an integrated sociocultural model and examined these pathways in multigroup structural equation models in a national sample of heterosexual, bisexual, and lesbian women (ns = 5395; 598; 213, respectively), and heterosexual, bisexual, and gay men (4869; 194; and 194, respectively) aged 18-65 years. Sexual orientation moderated some of these pathways. The most consistent pattern was that appearance pressures were internalized to a greater extent among bisexual participants. The pathways to poorer body image were generally similar among heterosexual and gay/lesbian men and women. These findings highlight the importance of examining sexual orientation-specific influences on body image across diverse groups, as well as the commonalities in the experiences of men and women across sexual orientations.

Racial identity differences in pathways from sociocultural and objectification constructs to body satisfaction: The U.S. Body Project I

Racial minority men and women face a wide variety of appearance-related pressures, including ones connected to their cultural backgrounds and phenotypic features associated with their identity. These body image concerns exist within a larger context, wherein racial minorities face pressures from multiple cultures or subcultures simultaneously to achieve unrealistic appearance ideals. However, limited research has investigated racial differences in the relationships between theorized sociocultural risk factors and body image in large samples. This study tests pathways from an integrated sociocultural model drawing on objectification theory and the tripartite influence model to three key body image outcomes: appearance evaluation, body image quality of life, and face image satisfaction. These pathways were tested using multigroup structural equation modeling in a national sample of White, Black, Hispanic, and Asian men and women (ns = 205-4797 per group). Although many hypothesized associations were similar in strength across groups, race moderated some of the pathways between sociocultural pressures (media, peer, family), internalization of appearance ideals (thin-ideal, muscular/athletic), appearance surveillance, and body image outcomes. Findings support the likely role of both shared and specific risk factors for body image outcomes, suggesting avenues for tailoring adapted interventions in order to target culturally-salient risk factors.

Weight gain attempts and diet modification efforts among adults in five countries: a cross-sectional study

BACKGROUND

Recent research has emphasized a growing trend of weight gain attempts, particularly among adolescents and boys and young men. Little research has investigated these efforts among adults, as well as the specific diet modifications individuals who are trying to gain weight engage in. Therefore, the aims of this study were to characterize the diet modification efforts used by adults across five countries who reported engaging in weight gain attempts and to determine the associations between weight gain attempts and concerted diet modification efforts.

METHODS

Cross-sectional data from the 2018 and 2019 International Food Policy Study, including participants from Australia, Canada, Mexico, the United Kingdom, and the United States (N = 42,108), were analyzed. In reference to the past 12 months, participants reported on weight gain attempts and diet modification efforts related to increased consumption of calories, protein, fiber, fruits and vegetables, whole grains, dairy products, all meats, red meat only, fats, sugar/added sugar, salt/sodium, and processed foods. Unadjusted (chi-square tests) and adjusted (modified Poisson regressions) analyses were conducted to examine associations between weight gain attempts and diet modification efforts.

RESULTS

Weight gain attempts were significantly associated with higher likelihood of each of the 12 forms of diet modification efforts among male participants, and 10 of the diet modification efforts among female participants. Notably, this included higher likelihood of efforts to consume more calories (males: adjusted prevalence ratio [aPR] 3.25, 95% confidence interval [CI] 2.94-3.59; females: aPR 4.05, 95% CI 3.50-4.70) and fats (males: aPR 2.71, 95% CI 2.42-3.03; females: aPR 3.03, 95% CI 2.58-3.55).

CONCLUSIONS

Overall, the patterns of association between weight gain attempts and diet modification efforts may be indicative of the phenomenon of muscularity-oriented eating behaviors. Findings further highlight the types of foods and nutrients adults from five countries may try to consume in attempts to gain weight.

Variability in Eating Disorder Risk and Diagnosis in Transgender and Gender Diverse College Students

PURPOSE

To examine differences in elevated eating disorder risk and self-reported eating disorder diagnosis across subgroups of transgender and gender diverse (TGD) college students.

METHODS

Data from 5057 TGD college students participating in the national Healthy Minds Study between 2014-2019 were analyzed. Chi-square tests and logistic regression analyses examined heterogeneity in prevalence and odds of elevated eating disorder risk, as measured by the SCOFF, and self-reported eating disorder diagnosis by gender, as well as by intersecting gender and sexual orientation identities.

RESULTS

Genderqueer/non-conforming college students reported the highest prevalence of elevated eating disorder risk (38.8%) relative to gender expansive students. Genderqueer/non-conforming (11.1%), gender expansive (12.3%), and trans men/transmasculine students (10.5%) reported higher prevalence of a self-reported eating disorder diagnosis relative to trans women/transfeminine students (6.3%). Heterosexual or straight trans men had lower odds of eating disorder risk and self-reported diagnosis relative to trans men with a minoritized sexual orientation.

CONCLUSIONS

Genderqueer/non-conforming college students may be at heightened eating disorder risk. Moreover, a heterosexual/straight sexual orientation was associated with lower odds of elevated eating disorder risk and self-reported eating disorder diagnoses among trans men and genderqueer/non-conforming college students, but this finding did not hold for other groups. College campuses should aim to reduce eating disorder risk among TGD students.

An abbreviated 10-item, two-factor version of the Body Image Quality of Life Inventory (BIQLI-10): The U.S. Body Project I

The objective of this study was to re-examine the factor structure of the Body Image Quality of Life Inventory (BIQLI), a measure that quantifies perceived effects of one's body image on various aspects of psychosocial functioning. Data on the 19-item BIQLI from a community sample of 11,620 U.S. men and women were split into cross-validation samples and underwent exploratory and confirmatory factor analysis. An abbreviated 10-item, two-factor version of the BIQLI (BIQLI-10) was identified. The BIQLI-10 measures Social Relations & Psychological Well-Being with one subscale and Appearance & Body Management Activities with the other. Internal consistency was high for each subscale. The BIQLI-10 largely retained the convergent validity of the original 19-item BIQLI, as evidenced by nearly identical correlations with appearance evaluation, overweight preoccupation, body surveillance, appearance pressures, and appearance ideal internalization. Results also supported strong measurement invariance for the BIQLI-10 by age group, gender, sexual orientation, racial group, and weight status. Findings from this study suggest researchers may use this abbreviated version to increase nuance in the measurement of body image quality of life and reduce participant burden without compromising the psychometric integrity of the BIQLI. Further, results support the comparison of BIQLI-10 subscale scores across diverse groups.

Everyday discrimination as a predictor of maladaptive and adaptive eating: Findings from EAT 2018

Various types of stressors are associated with maladaptive eating, but how the stressor of everyday discrimination (e.g., less respect, poorer service) relates to maladaptive eating and adaptive eating remains unclear. We examined everyday discrimination as a predictor of maladaptive and adaptive eating. Data were collected in a population-based study, Eating and Activity over Time (N = 1410, ages 18-30). Everyday discrimination was categorized as none, low, moderate, or high. Outcomes included maladaptive eating (i.e., overeating and binge eating) and adaptive eating (i.e., intuitive eating and mindful eating). Modified Poisson regressions estimated the prevalence ratios (PRs) for overeating and binge eating associated with everyday discrimination. Linear regressions estimated associations between everyday discrimination and intuitive and mindful eating scores. After adjustment for age, ethnicity/race, gender, and socioeconomic status, moderate and high levels of discriminatory experiences were each associated with a significantly greater prevalence of binge eating (PR = 2.2, [95% CI = 1.3-3.7] and PR = 3.1, [95% CI = 2.0-4.7], respectively) and lower intuitive (β = -0.4, [95% CI = -0.7, -0.2] and β = -0.5 [95% CI = -0.8, -0.3], respectively), and mindful eating scores (β = -0.3, [95% CI = -0.6, -0.1] and β = -0.5 [95% CI = -0.8, -0.3], respectively) compared to young adults with no discriminatory experience. Public health efforts to prevent maladaptive eating and encourage the adoption of adaptive eating should consider the potential contribution of everyday discrimination and the need to advocate for equity and inclusion.

Muscle-building behaviors from adolescence to emerging adulthood: a prospective cohort study

•

Muscle-building behaviors in adolescence to emerging adulthood were studied.

•

Starting muscle-building behaviors is common from adolescence to emerging adulthood.

•

Prevalence of any protein powder/shakes use was 55.1% in males and 33.0% in females.

•

Prevalence of any steroids use was 6.7% in males and 5.4% in females.

•

Protein powder consumption was associated with future use of steroids.

This study aimed to identify patterns of change in muscle-building behaviors from adolescence to emerging adulthood and determine what adolescent factors predict new-onset muscle-building behavior in emerging adulthood. Prospective cohort data from a diverse sample of 1,535 participants followed from adolescence (baseline, M_age = 14.4 ± 2.0 years) to emerging adulthood (follow-up, M_age = 22.1 ± 2.0 years) from the population-based EAT 2010–2018 (Eating and Activity over Time) study were analyzed. Changes in muscle-building behavior were identified (starting, stopping, persistent use, or never use). Log-binomial regression models examined adolescent predictors of starting (i.e., new-onset) muscle-building behaviors in emerging adulthood. Prevalence of any use in adolescence (EAT 2010) and/or emerging adulthood (EAT 2018) was 55.1% (males) and 33.0% (females) for protein powder/shakes, 6.7% (males) and 5.4% (females) for steroids, and 19.4% (males) and 6.5% (females) for other muscle-building substances (e.g., creatine, amino acids). In particular, 22.6% (males) and 13.7% (females) started protein powder/shakes, 2.2% (males) and 1.0% (females) started steroid use, and 9.0% (males) and 2.0% (females) started other muscle-building substances during emerging adulthood. Adolescent protein powder/shake consumption was associated with starting steroids/other muscle-building substances use in emerging adulthood in males (adjusted risk ratio [ARR] 2.09, 95% confidence interval [CI] 1.29–3.39) and females (ARR 4.81, 95% CI 2.01–11.48). Adolescent use of protein powders/shakes may lead to a two- to five-fold higher risk of new use of steroids and other muscle-building products in emerging adulthood. Clinicians, parents, and coaches should assess for use of muscle-building behaviors in adolescents and emerging adults and discourage use of harmful products.

Food insecurity is associated with eating disorders independent of depression and anxiety: Findings from the 2020-2021 Healthy Minds Study

OBJECTIVE

To examine the association between food insecurity and eating disorder (ED) risk independent of co-occurring anxiety/depression.

METHOD

Data were provided by 121,627 undergraduate/graduate students who participated in the 2020-2021 Healthy Minds Study (HMS). Participants responded to questionnaire measures of food insecurity and risk for EDs, depression, and anxiety. Established cut-offs were used to identify students with food insecurity and probable psychopathology. Separate modified Poisson regressions adjusted for age, gender, race/ethnicity, and socioeconomic background examined the association between food insecurity and each form of psychopathology. The association between food insecurity and probable ED was then examined in a regression further adjusted for probable depression and anxiety.

RESULTS

Food insecurity was significantly associated with all three forms of psychopathology when examined separately (prevalence ratios ranged from 1.41 to 1.54, all p's < .001). When accounting for probable depression/anxiety, food insecurity was significantly associated with 1.19 times greater prevalence of a probable ED (p < .001).

DISCUSSION

The association between food insecurity and EDs was replicated in a large, national sample of university students. To our knowledge, this is the first study to examine the independence of this relationship after adjusting for depression/anxiety. This finding supports the hypothesis that specific mechanisms, rather than general psychological distress, likely underlie the food insecurity-ED relationship.

Using apps to self-monitor diet and physical activity is linked to greater use of disordered eating behaviors among emerging adults

Use of weight-related self-monitoring (WRSM) apps is common among emerging adults, as are weight and shape concerns. The present study aimed to examine (1) whether emerging adult use of dietary-focused (e.g., MyFitnessPal) and physical activity-focused (e.g., Fitbit) WRSM apps was associated with weight-control and muscle-building behaviors, including commonly recommended/conventional behaviors and disordered behaviors and (2) whether prior use of weight-control and muscle-building behaviors in adolescence might explain such relationships. Data were collected as part of the EAT (Eating and Activity over Time) 2010-2018 study (n = 1446) and analyzed using gender-stratified logistic regression models adjusted for demographic characteristics and body mass index. Among women and men, physical activity- and dietary-focused app use were associated with greater adjusted prevalence of disordered weight-control behaviors (e.g., fasting, purging), and disordered muscle-building behaviors (e.g., using steroids). Physical activity- and dietary-focused app use were also associated with a higher adjusted prevalence of commonly recommended weight-control and conventional muscle-building behaviors (e.g., exercising, changing eating habits), but only among those who were also engaging in disordered behaviors. The observed associations remained statistically significant in models that further adjusted for adolescent use of the respective behaviors. Findings suggest that emerging adults who use physical activity- and dietary-focused WRSM apps are more likely to engage in disordered weight-control and muscle-building behaviors and that associations are not explained by engagement in these behaviors during adolescence. Future research is needed to examine if there are aspects of WRSM apps that could be modified to reduce potential harm.

Digital technology use and muscle-building behaviors in young adults

OBJECTIVE

Digital technology use and muscle-building behaviors reflect a wide range of behaviors with associated health risks. However, links between digital technology use and muscle-building behaviors remain unknown and this study aimed to address this gap.

METHOD

Data were collected from a diverse sample of 1,483 young adults (mean age 22.2 ± 2.0 years) participating in the population-based Eating and Activity over Time 2018 study. Gender-stratified-modified Poisson regression models were used to determine cross-sectional associations between three types of digital technology use (screen time, social media, weight-related self-monitoring apps) and five types of muscle-building behaviors (changing eating, exercise, protein powders/shakes, pre-workout drinks, steroids/growth hormone/creatine/amino acids) in young adulthood, adjusted for sociodemographic characteristics and body mass index.

RESULTS

Screen time and social media were either not found to be associated with muscle-building behaviors or in a few instances, associated with less use of these behaviors (e.g., screen time and pre-workout drinks in men). In contrast, the use of weight-related self-monitoring apps was positively associated with all muscle-building behaviors, including steroids/growth hormone/creatine/amino acids in men (prevalence ratio [PR] = 1.83; 95% confidence interval [CI]: 1.13-2.97) and women (PR = 4.43; 95% CI: 1.68-11.68).

DISCUSSION

While most recreational screen time may represent sedentary behaviors not related to muscle-building behaviors, weight-related self-monitoring apps are highly associated with more muscle-building behaviors and could be a future target for interventions to discourage the use of steroids and other harmful muscle-building substances.

Adverse experiences as predictors of maladaptive and adaptive eating: Findings from EAT 2018

Adverse experiences, such as childhood abuse and other violence victimization, are associated with problematic eating. However, whether different types of adversity relate to both maladaptive and adaptive eating behaviors is unclear. This study examined the associations of different adverse experiences with maladaptive (i.e., overeating and binge eating) and adaptive (i.e., intuitive eating and mindful eating) eating by gender. Data were derived from the EAT-2018 (Eating and Activity over Time) study (N = 1411, aged 18-30 years in 2017-2018). Modified Poisson regressions were used to examine the associations between adverse experiences and the prevalence of maladaptive eating. Linear regressions were used to examine the associations between adverse experiences and adaptive eating scores. Each adverse experience was associated with greater prevalence of maladaptive eating and lower adaptive eating scores. Among women, intimate partner sexual violence was strongly associated with more overeating (PR = 2.1 [95% CI = 1.4-3.1]) and binge eating (PR = 2.4 [95% CI = 1.5-3.9]), and less mindful eating (β = -0.6, [95% CI = -0.8, -0.3]); being attacked, beaten, or mugged was most associated with less intuitive eating (β = -0.5, [95% CI = -0.8, -0.2]). Among men, being attacked, beaten, or mugged was strongly associated with more overeating (PR = 2.1 [95% CI = 1.2-3.5]) and binge eating (PR = 3.2 [95% CI = 1.6-6.5]); intimate partner physical violence was strongly associated with less intuitive eating (β = -0.6, [95% CI = -0.9, -0.2]); childhood emotional abuse was strongly associated with less mindful eating (β = -0.8, [95% CI = -1.0, -0.5]). To improve eating behaviors, adverse life experiences and the potential impact on maladaptive and adaptive eating should be considered.

A 1-year follow-up study of the longitudinal interplay between emotion dysregulation and childhood trauma in the treatment of anorexia nervosa

OBJECTIVE

The study aimed to investigate the complex relationship between eating disorder (ED) specific psychopathology, emotion dysregulation, and their longitudinal variations in patients with anorexia nervosa (AN) treated with a multidisciplinary approach including enhanced cognitive-behavior therapy (CBT-E), and to provide an integrated model which includes childhood trauma as a predictor of worse treatment outcomes.

METHOD

In total, 120 female patients with AN were evaluated at admission (T0), and 105 were re-evaluated after 1 year (T1) of treatment. At T0, patients underwent a clinical assessment and filled the Symptom Checklist 90-Revised (SCL90-R), the Eating Disorders Examination Questionnaire (EDE-Q), the Difficulties in Emotion Regulation Scale (DERS), and the Childhood Trauma Questionnaire (CTQ). SCL-90-R, EDE-Q, and DERS were readministered at T1. Variations between T0 and T1 were evaluated, and the proposed model was investigated using bivariate latent change score analysis in a structural equation modeling (SEM) framework.

RESULTS

An overall significant clinical amelioration was observed after treatment. A unidirectional effect of DERS scores on EDE-Q variations was outlined by SEM: patients with higher baseline DERS scores achieved less EDE-Q improvements, and EDE-Q latent change score was significantly predicted by longitudinal variations of DERS-but not vice versa. Higher CTQ scores predicted reduced treatment efficacy for ED-specific psychopathology through the mediating effect of higher baseline DERS scores.

DISCUSSION

The present study sheds light on the mechanism by which early trauma compromises treatment outcome in patients with AN, underlining the crucial role of emotional dysregulation.

Micro-level de-coupling of negative affect and binge eating in relationship to macro-level outcomes in binge eating disorder treatment

BACKGROUND

While negative affect reliably predicts binge eating, it is unknown how this association may decrease or 'de-couple' during treatment for binge eating disorder (BED), whether such change is greater in treatments targeting emotion regulation, or how such change predicts outcome. This study utilized multi-wave ecological momentary assessment (EMA) to assess changes in the momentary association between negative affect and subsequent binge-eating symptoms during Integrative Cognitive Affective Therapy (ICAT-BED) and Cognitive Behavior Therapy Guided Self-Help (CBTgsh). It was predicted that there would be stronger de-coupling effects in ICAT-BED compared to CBTgsh given the focus on emotion regulation skills in ICAT-BED and that greater de-coupling would predict outcomes.

METHODS

Adults with BED were randomized to ICAT-BED or CBTgsh and completed 1-week EMA protocols and the Eating Disorder Examination (EDE) at pre-treatment, end-of-treatment, and 6-month follow-up (final N = 78). De-coupling was operationalized as a change in momentary associations between negative affect and binge-eating symptoms from pre-treatment to end-of-treatment.

RESULTS

There was a significant de-coupling effect at follow-up but not end-of-treatment, and de-coupling did not differ between ICAT-BED and CBTgsh. Less de-coupling was associated with higher end-of-treatment EDE global scores at end-of-treatment and higher binge frequency at follow-up.

CONCLUSIONS

Both ICAT-BED and CBTgsh were associated with de-coupling of momentary negative affect and binge-eating symptoms, which in turn relate to cognitive and behavioral treatment outcomes. Future research is warranted to identify differential mechanisms of change across ICAT-BED and CBTgsh. Results also highlight the importance of developing momentary interventions to more effectively de-couple negative affect and binge eating.

Stay-at-Home Orders during COVID-19: The Influence on Physical Activity and Recreational Screen Time Change among Diverse Emerging Adults and Future Implications for Health Promotion and the Prevention of Widening Health Disparities

BACKGROUND

The purpose of this study was to examine changes in physical activity (PA) and recreational screen time (RST) behaviors from pre-COVID-19 in 2018 to Spring 2020 during the mandatory stay-at-home order in an ethnically/racially, socioeconomically diverse sample of emerging adults.

METHODS

Longitudinal data were analyzed from 218 participants (Mage = 24.6 ± 2.0 years) who completed two surveys: EAT 2018 (Eating and Activity over Time) and C-EAT in 2020 (during COVID-19). Repeated ANCOVAs and multiple linear regression models were conducted.

RESULTS

Moderate-to-vigorous and total PA decreased (4.7 ± 0.3 to 3.5 ± 0.3 h/week [p < 0.001] and 7.9 ± 0.4 to 5.8 ± 0.4 h/week [p < 0.001], respectively), and RST increased from 26.5 ± 0.9 to 29.4 ± 0.8 h/week (p = 0.003). Perceived lack of neighborhood safety, ethnic/racial minoritized identities, and low socioeconomic status were significant predictors of lower PA and higher RST during COVID-19. For example, low SES was associated with 4.04 fewer hours of total PA compared to high SES (p < 0.001).

CONCLUSIONS

Stay-at-home policies may have significantly influenced PA and RST levels in emerging adults with pre-existing disparities exacerbated during this mandatory period of sheltering-in-place. This suggests that the pandemic may have played a role in introducing or magnifying these disparities. Post-pandemic interventions will be needed to reverse trends in PA and RST, with a focus on improving neighborhood safety and meeting the needs of low socioeconomic and ethnic/racial minoritized groups.

Adverse childhood experiences in relation to mood-, weight-, and eating-related outcomes in emerging adulthood: Does self-compassion play a buffering role?

BACKGROUND

Adverse childhood experiences (ACEs) are associated with a range of health problems, yet protective factors such as self-compassion may help buffer these associations.

OBJECTIVE

This study examined associations of distinct patterns of ACEs with depressive symptoms, body mass index (BMI), and disordered eating symptoms and investigated self-compassion as a potential protective factor.

PARTICIPANTS AND SETTING

Data from a diverse sample of 1440 emerging adults (M_age = 22.2 years; 53.7% female; 80.3% with race/ethnicity other than non-Hispanic white) came from the population-based EAT 2018 (Eating and Activity over Time) study.

METHODS

Seven types of ACEs were retrospectively self-reported and used as model indicators in latent class analysis to identify patterns of ACEs. Self-compassion, depressive symptoms, height and weight (to calculate BMI), and disordered eating symptoms were also assessed. Demographic-adjusted regression models were conducted.

RESULTS

Three latent classes emerged: "low ACEs" (66.5% of the sample), "household dysfunction" (24.3%), and "household dysfunction and abuse" (9.1%). Compared to participants in the "low ACEs" class, participants in either latent class involving household dysfunction demonstrated higher levels of depressive and disordered eating symptoms. Participants in the "household dysfunction and abuse" class also had higher BMI. Associations differed by self-compassion for depressive symptoms (p_interaction = 0.01), BMI (p_interaction = 0.03), and disordered eating symptoms (p_interaction = 0.005), such that associations for latent classes characterized by ACEs were weaker with higher levels of self-compassion.

CONCLUSIONS

These findings suggest self-compassion may act as a buffer against adverse mood-, weight-, and eating-related outcomes in the face of adversity and therefore may be an important intervention target.
