Sexual Minority Women Report Higher Weight Stigma Levels Than Heterosexual Women in the National Weight Control Registry.

BACKGROUND: Little is known about weight stigma in sexual minority women, and even less is known about weight stigma in those who have attained substantial weight loss and maintenance. PURPOSE: This study examined weight stigma experiences and internalization in sexual minority women from the National Weight Control Registry (NWCR) who had lost ≥30 pounds and maintained this weight loss for ≥1 year, and compared weight stigma levels between sexual minority women versus heterosexual women in the NWCR. METHODS: NWCR participants completed an electronic survey. Women who identified as a sexual minority (n = 64; 98% White; MBMI = 29 ± 8; Mage = 47 ± 13) and heterosexual women matched on body mass index (BMI), age, and race (n = 64; 98% White; MBMI = 28 ± 7; Mage = 51 ± 13) were included. Participants completed assessments of experienced and internalized weight stigma. RESULTS: Generalized linear models showed that a significantly larger proportion of sexual minority women in the NWCR reported experiencing weight stigma in the past year (24.2%) compared with heterosexual women (4.7%; p < .05). Furthermore, sexual minority (vs. heterosexual) women reported significantly higher levels of internalized weight stigma (p < .001), and a greater proportion of sexual minority women (35%) reported clinically significant internalized weight stigma relative to heterosexual women (2%; p < .001). CONCLUSIONS: Sexual minority women are at greater risk for experienced and internalized weight stigma than their heterosexual counterparts among women who have attained significant long-term weight loss. It is critical to expand research on weight stigma in sexual minority women.

This study examined weight stigma experiences and internalization in sexual minority women who attained substantial weight loss and maintenance, compared with heterosexual women of similar body mass index (BMI), race, and age, in a sample of adults from the National Weight Control Registry. Results showed that 24% of sexual minority women reported experiencing weight stigma in the past year and 35% reported clinically meaningful internalized weight stigma, levels that were higher than those of heterosexual women of similar BMI, age, and race in the sample. These data suggest that sexual minority women who have attained major weight loss may be at greater risk for weight stigma than heterosexual women with similar weight losses.

Evaluating the effect of targeting body shape concerns on long-term weight change.

OBJECTIVE: The goal of this follow-up to a randomized proof-of-concept study was to determine if targeting body shape concern (BSC) has a clinically significant impact on long-term weight change among adult women of higher body weight with BSC. A secondary aim was to observe the maintenance of body image improvements during follow-up. METHOD: In the original 4-week trial, women were randomized to behavioral weight loss recommendations alone (control; n = 15) or combined with the evidence-based body project intervention (n = 17). All participants were directed to continue monitoring diet and exercise through Week 8. The current analysis focused on follow-up data collected on weight, BSC, internalized weight bias, internalized thin ideal, and body appreciation at 8 weeks, 6 months, and 12 months. Percent weight change was calculated from baseline and compared against clinical milestones of -2.5% and -5%. An intent-to-treat approach was used for individuals lost to follow-up (n = 11). RESULTS: Body project participants achieved the clinically significant target of -2.5% weight loss by 12 months. Control participants did not reach the milestone and regained lost weight at 12 months. Neither condition reached the 5% clinical target. Both groups experienced improved body image, but body project participants maintained a greater magnitude of improvement in all measures except internalized thin ideal at 12 months. CONCLUSION: The current study provides preliminary evidence that targeting BSC among women with BSC who want to lose weight may improve long-term weight loss. Further intervention development and testing are warranted. PUBLIC SIGNIFICANCE: The results of this study suggest that targeting negative body image among adult women with high BSC might be a pathway to improve long-term weight loss in behavioral weight management. This is aligned with precision medicine priorities to optimize weight-related health care.

Associations that Cardiorespiratory Fitness and Body Mass Index Loss Have with Deficit Accumulation Frailty.

INTRODUCTION/PURPOSE: Lower cardiorespiratory fitness and obesity may accelerate aging processes. The degree to which changes in fitness and body mass index (BMI) may alter the rate of aging may be important for planning treatment. We assessed cross-sectional and longitudinal associations that cardiorespiratory fitness and BMI had with a deficit accumulation frailty index (FI). METHODS: Fitness, based on standardized graded exercise tests, and weight to calculate BMI at baseline and year 4 were collected from 3944 participants aged 45-76 yr in the Action for Health in Diabetes (Look AHEAD) randomized controlled clinical trial. A validated 38-item deficit accumulation FI was used as a marker of aging. Associations between baseline and changes in fitness and BMI with changes in FI were assessed using linear models. RESULTS: Both baseline and 4-yr changes in fitness and BMI were independently associated with 4-yr changes in frailty (all P < 0.001). Mean (95% confidence interval) changes in FI ranged from -0.019 (-0.024, -0.013) for participants in the group with the greatest fitness increase and BMI loss to 0.029 (0.024, 0.034) for participants in the group with the greatest fitness loss and BMI gain. Associations of 4-yr changes in fitness and BMI with FI changes were similar across subgroups based on age, sex, baseline BMI, diabetes duration, and cardiovascular disease history. Increased fitness across 4 yr was associated with less FI accumulation independent of baseline fitness. CONCLUSIONS: Adults with type 2 diabetes and overweight or obesity may slow aging processes captured by an FI by increasing their cardiorespiratory fitness and losing weight.

Association of weight and shape concern with weight change and weight-related behaviors in behavioral weight loss treatment.

Weight and shape concern (WSC) is a facet of negative body image that is common among individuals with overweight/obesity seeking behavioral weight loss treatment (BWL), but remains understudied. This secondary analysis evaluates associations between WSC, weight change, and weight-related behaviors among individuals in a 24-week BWL. Adults (n = 32) with body mass index 25-50 kg/m2 completed a baseline WSC questionnaire, measured weight at 12 and 24 weeks, measured physical activity via accelerometer, and completed 24-hour dietary recalls. Adherence to self-monitoring dietary intake and weight were assessed. A series of linear mixed models were used to evaluate associations between baseline WSC and weight change, as well as weight-related behaviors. Results revealed no significant effect of WSC on weight change. There were significant WSC x time interactions, such that those rating WSC "very important" decreased self-weighing and the "low importance" group decreased their caloric intake during treatment. The "pretty important" group had greater minutes of activity than the "low importance" group. Findings indicated that WSC may impact weight-related behaviors that contribute to BWL success. This trial was pre-registered on ClinicalTrials.gov (NCT03739151).

Association of Weight-Related Stigmas With Daily Pain Symptoms Among Individuals With Obesity.

BACKGROUND: Individuals with obesity are disproportionately impacted by pain-related symptoms. PURPOSE: This study evaluated experienced weight stigma and internalized weight bias (IWB) as predictors of pain symptoms in daily life among individuals with obesity. METHODS: Adults with obesity (n = 39; 51% female, 67% White, 43.8 ± 11.6 years old, BMI = 36.8 ± 6.7 kg/m2) completed a baseline assessment (demographics, experienced weight stigma, IWB) and a 14-day Ecological Momentary Assessment (EMA) period involving five daily prompts of pain/aches/joint pain, muscle soreness, experienced weight stigma, and IWB. Generalized linear models were used to assess experienced weight stigma and IWB at baseline as prospective predictors of EMA pain/soreness symptoms. Multi-level models were used to test the association of momentary weight stigma experiences and IWB with pain/soreness at the same and subsequent EMA prompts. RESULTS: IWB at baseline, but not experienced weight stigma, was associated with more frequent pain symptoms (p < .05) and muscle soreness (p < .01) during EMA. Momentary IWB (but not experienced stigma) was associated with more pain/aches/joint pain and muscle soreness at the same and subsequent prompt. CONCLUSIONS: Internalized (but not experienced) weight bias was prospectively associated with pain symptoms in daily life among individuals with obesity. Results are consistent with growing evidence that weight-related stigmas represent psychosocial factors that contribute to weight-related morbidity typically attributed to body size.

Weight changes during the COVID-19 shutdown in older individuals with type 2 diabetes: the Look AHEAD Study.

OBJECTIVE: The aims of this study were as follows: 1) examine weight changes in older adults (mean age = 76 years) with type 2 diabetes and overweight or obesity during the COVID-19 shutdown; and 2) compare the behavioral and psychosocial effects of the shutdown in those who had large weight losses (>5%), those who had small weight losses (2%-5%), those who remained weight stable (±2%), or those who gained weight (>2%). METHODS: Look AHEAD (Action for Health in Diabetes) participants (N = 2544) were surveyed during the COVID-19 shutdown (2020), and they self-reported their current weight, reasons for weight change, weight-related behaviors, psychosocial measures, and negative and positive effects of the pandemic on their lives. RESULTS: Comparing self-reported weight during the COVID-19 shutdown with earlier measured weight, Look AHEAD participants lost, on average, 2.2 kg during the COVID-19 shutdown: 47% lost >2%, and only 18% gained >2% (p < 0.0001). Decreases in physical activity and increases in screen time were reported frequently in all weight-change categories. Similarly, there were few differences among the categories on standardized psychosocial measures or self-reported effects of the shutdown on participants' lives. However, when differences were seen, the most negative impact was in those who gained weight. CONCLUSIONS: Although weight loss appeared more common than weight gain during the shutdown, the weight-change groups did not differ on most psychosocial and behavioral variables.

Examining the role of experiential avoidance and valued action in the negative effects of weight self-stigma.

Harmful effects of weight self-stigma on quality of life and health behaviors have been well-established. However, the processes that lead to these negative outcomes are less understood. Psychological inflexibility is defined as a pattern of rigid psychological reactions dominating over values and meaningful actions. A lack in valued action is characterized by the absence of activities that are connected to what is personally meaningful. In this secondary analysis, we aim to extend research by examining two subprocesses of psychological inflexibility, experiential avoidance and lack of valued action, as statistical mediators of the relations between weight self-stigma and quality of life/health behavior outcomes. Baseline data from a clinical trial comparing weight loss maintenance interventions in a sample of 194 adults living with overweight or obesity and seeking treatment is analyzed. Results show that greater experiential avoidance and lower valued action were significantly related to lower quality of life and satisfaction with social roles, as well as greater depression, anxiety, and binge eating. Further, results from a parallel mediation analysis indicated that weight self-stigma is indirectly related to anxiety, disinhibited eating, and hunger through the relationship with experiential avoidance and lack of valued action.

Psychological resilience in older adults with type 2 diabetes from the Look AHEAD Trial.

BACKGROUND: There is growing interest in identifying factors associated with healthy aging. This cross-sectional study evaluated associations of psychological resilience with factors associated with aging in older adults with type 2 diabetes mellitus (T2DM). METHODS: Participants were 3199 adults (72.2 ± 6.2 years of age, 61% female, 61% White, body mass index [BMI] = 34.2 ± 8.2 kg/m2 ) with T2DM enrolled in Look AHEAD (a multi-site randomized clinical trial comparing an intensive lifestyle intervention for weight loss to diabetes education and support). Participants were followed observationally after the 10-year intervention was discontinued. The following items were assessed approximately 14.4 years post-randomization in a cross-sectional analysis: Brief Resilience Scale; overnight hospitalizations in past year; physical functioning measured objectively (gait speed, grip strength) and via self-report (Pepper Assessment Tool for Disability; physical quality of life [QOL; SF-36]); a measure of phenotypic frailty based on having ≥3 of unintentional weight loss, low energy, slow gait, reduced grip strength, and physical inactivity. Depressive symptoms (PHQ-9) and mental QOL (SF-36) were also measured. Logistic/linear/multinomial regression was used to evaluate the association of variables with resilience adjusted for age, race/ethnicity, and gender. RESULTS: Greater psychological resilience was associated with lower BMI, fewer hospitalizations, better physical functioning (i.e., lower self-reported disability, better physical QOL, faster gait speed, greater grip strength, lower likelihood of frailty), fewer depressive symptoms, and greater mental QOL (all p < 0.05). Psychological resilience moderated the relationship of number of hospitalizations in the past year with self-reported disability and grip strength. CONCLUSIONS: Psychological resilience is associated with better physical function and QOL among older adults. Results should be interpreted cautiously given cross-sectional nature of analyses. Exploring the clinical benefits of resilience is consistent with efforts to shift the narrative on aging beyond "loss and decline" to highlight opportunities to facilitate healthy aging.

Internalized weight stigma in women with class III obesity: A randomized controlled trial of a virtual lifestyle modification intervention followed by a mindful self-compassion intervention.

Background: Internalized weight stigma (Internalized-WS) is prevalent among individuals with severe obesity, particularly women, and is associated with shame, disordered eating, and weight gain. Effective, accessible interventions that address both severe (Class-III) obesity and Internalized-WS are needed. This randomized pilot trial evaluated the feasibility, acceptability, and preliminary efficacy of a fully-remote lifestyle modification intervention (LM) followed by mindful self-compassion training (MSC) or control. Methods: Twenty-eight women with Class-III obesity (46.6 ± 3.7 kg/m2) and elevated Internalized-WS were randomized to a virtually-delivered 4-month LM followed by a 2-month MSC or cooking/dietary education (CON). Psychosocial measures/weight were assessed at baseline, 4-(post-LM), 6-(post-MSC/CON), and 9-month (follow-up). Results: Improvements in Internalized-WS, shame, and self-compassion were observed with LM. Mean 4-month weight loss was 6.3 ± 3.7%. MSC had lower attendance and usefulness ratings versus CON. Post-MSC/CON, MSC yielded significant and/or meaningful improvements in Internalized-WS, self-compassion, and intuitive eating relative to CON. Weight loss did not differ by group at 6-month, and at 9-month trended lower in MSC versus CON. Conclusion: Virtual LM is feasible, acceptable, and leads to significant weight loss among women with severe obesity; MSC led to further improved Internalized-WS, self-compassion, and intuitive eating. Continued work is needed to elucidate effects of self-compassion training on Internalized-WS, its mechanisms, and linkages to cardiometabolic health and long-term weight loss.

Weight Change During the Postintervention Follow-up of Look AHEAD.

OBJECTIVE: Patients with type 2 diabetes are encouraged to lose weight, but excessive weight loss in older adults may be a marker of poor health and subsequent mortality. We examined weight change during the postintervention period of Look AHEAD, a randomized trial comparing intensive lifestyle intervention (ILI) with diabetes support and education (DSE) (control) in overweight/obese individuals with type 2 diabetes and sought to identify predictors of excessive postintervention weight loss and its association with mortality. RESEARCH DESIGN AND METHODS: These secondary analyses compared postintervention weight change (year 8 to final visit; median 16 years) in ILI and DSE in 3,999 Look AHEAD participants. Using empirically derived trajectory categories, we compared four subgroups: weight gainers (n = 307), weight stable (n = 1,561), steady losers (n = 1,731), and steep losers (n = 380), on postintervention mortality, demographic variables, and health status at randomization and year 8. RESULTS: Postintervention weight change averaged -3.7 ± 9.5%, with greater weight loss in the DSE than the ILI group. The steep weight loss trajectory subgroup lost on average 17.7 ± 6.6%; 30% of steep losers died during postintervention follow-up versus 10-18% in other trajectories (P < 0001). The following variables distinguished steep losers from weight stable: baseline, older, longer diabetes duration, higher BMI, and greater multimorbidity; intervention, randomization to control group and less weight loss in years 1-8; and year 8, higher prevalence of frailty, multimorbidity, and depressive symptoms and lower use of weight control strategies. CONCLUSIONS: Steep weight loss postintervention was associated with increased risk of mortality. Older individuals with longer duration of diabetes and multimorbidity should be monitored for excessive unintentional weight loss.

HIV Status, Obesity, and Risk for Weight Stigma: Comparing Weight Stigma Experiences and Internalization Among Adults with Obesity with and Without HIV.

Little is known about weight stigma among people living with HIV (PLWH). This study examined whether levels of perceived weight stigma experiences and internalization, assessed retrospectively and naturalistically, differed among adults with obesity based on HIV status. 50 PLWH (BMI = 35 kg/m2) and 51 adults without HIV (BMI = 36 kg/m2) completed retrospective assessments of lifetime perceived weight stigma experiences/internalization. Next, participants were invited to complete an optional 2-week Ecological Momentary Assessment study. 28 PLWH and 39 adults without HIV completed five momentary assessments of perceived weight stigma experiences/internalization daily. In covariate-adjusted models, PLWH reported 1.2-2.8 times lower frequency of lifetime and momentary perceived weight stigma experiences than adults without HIV, but levels of retrospectively- and naturalistically-assessed internalized weight stigma did not differ between groups. Findings suggest that HIV status may buffer against perceptions of weight stigma events, but not internalized weight stigma, highlighting weight stigma as an important area for future research in PLWH.

Internalized weight bias is associated with perceived exertion and affect during exercise in a sample with higher body weight.

OBJECTIVE: For individuals with overweight/obesity, internalized weight bias (IWB) is linked to low physical activity (PA). This study used a laboratory-based paradigm to test the hypothesis that IWB moderates the association between heart rate (HR) and perceived exertion and affect during PA. METHODS: Participants with overweight/obesity completed 30-min of supervised moderate-intensity treadmill walking (65%-75% of age-predicted maximal HR). Body Mass Index (BMI) and Weight Bias Internalization Scale were assessed at baseline. HR was monitored every minute; perceived exertion and affect were assessed every 5 min. Linear mixed models were employed with random effects of time and participant. RESULTS: The sample (n = 59; 79.7% female, 91.5% white) had an average BMI = 32.1 kg/m2 (SD: 3.3), and age = 47.1 (SD: 10.3) years. There was a main effect of IWB on perceived exertion (greater IWB was associated with greater perceived exertion during exercise; p < 0.001). There was an interaction of IWB and HR on affect (B = -0.01, p < 0.01). For individuals with high IWB, HR elevations were associated with a negative affective response during exercise. For individuals with low IWB, HR elevations were associated with increased positive affect during PA. CONCLUSIONS: Findings indicate that among individuals of higher body weight, IWB is associated with reporting higher perceived exertion during 30 min of moderate intensity PA. IWB moderated the relationship between increasing HR during exercise and affect. Among individuals with overweight/obesity who report IWB, the initial experience of PA may be harder and more unpleasant, with lasting implications for the adoption of PA.

Strategies to manage weight during the holiday season among US adults: A descriptive study from the National Weight Control Registry.

BACKGROUND: Holidays are challenging for weight control and are consistently associated with weight gain. Managing holiday weight gain may be especially difficult for individuals with higher body weight or a history of overweight/obesity. The current study evaluated how individuals with a history of successful weight loss plan for the holiday season and how the use of weight control strategies was associated with weight change. METHODS: A subgroup of participants in the National Weight Control Registry (NWCR) were asked to complete a survey before (November) and after the holidays (January). At pre-holiday, participants reported height, weight, and weight goals for the holiday season (lose, maintain, minimize gains, or gain), and selected the top three weight control strategies they planned to use (from a list of 18). Post-holiday, participants reported weight and how often (frequently, infrequently, or not at all) they used each of the 18 strategies throughout the holidays. RESULTS: Individuals who completed both surveys were included in the analysis (n = 683; 69% female, 93% white, 54.6 years [SD: 13.2], 26.9 kg/m2 [SD: 5.5]). Pre-holiday, 64% of participants were currently trying to lose weight. Only 35% of the sample wanted to continue losing weight during the holiday season. The most common strategies individuals planned to use during the holiday season were evidence based (maintaining exercise, monitoring portions, tracking foods, and self-weighing). Participants gained 0.66 kg (SD: 1.85) from pre- to post-holiday and reported using an average of 12/18 strategies. A greater number of strategies were associated with less weight gain (F[1, 670] = 4.28, p = 0.04). Daily self-weighing (p = 0.03) and prioritizing food choices (p = 0.02) were individually associated with less weight gain. DISCUSSION: Participants in the NWCR entered the holiday season with a variety of goals for their weight and used many different strategies to control their weight. Having a wider range of strategies may be helpful to navigate the challenges to weight control during the holidays.

State versus trait weight, shape, and eating concerns: Disentangling influence on eating behaviors among sexual minority women.

This study examined the relative influence of trait and state weight, shape, and eating concerns on dysregulated eating in the daily lives of sexual minority women with overweight and obesity. This study is a secondary analysis of data from an Ecological Momentary Assessment (EMA) study of 55 sexual minority women with overweight/obesity. Trait shape, weight, and eating concerns were assessed at baseline. For the following five days, participants used a smartphone to report state weight/shape concerns, overeating, and binge eating five times daily. Women who endorsed higher levels of trait weight, shape, and eating concerns at baseline reported more frequent state weight/shape concerns in daily life. Trait eating concerns were associated with higher odds of binge eating during EMA, but trait weight/shape concerns were unrelated to future dysregulated eating. In daily life, state weight/shape concerns was associated with greater risk for over/binge eating at the concurrent EMA prompt, the subsequent EMA prompt, and over the course of a full day, independent of trait concerns. State weight and shape concerns may play an important role in predicting dysregulated eating in daily life among sexual minority women of higher body weight.

Association of Baseline and Longitudinal Changes in Body Composition Measures With Risk of Heart Failure and Myocardial Infarction in Type 2 Diabetes: Findings From the Look AHEAD Trial.

BACKGROUND: Intentional weight loss is associated with lower risk of heart failure (HF) and atherosclerotic cardiovascular disease among patients with type 2 diabetes. However, the contribution of baseline measures and longitudinal changes in fat mass (FM), lean mass (LM), and waist circumference (WC) to the risk of HF and myocardial infarction (MI) in type 2 diabetes is not well established. METHODS: Adults from the Look AHEAD trial (Action for Health in Diabetes) without prevalent HF were included. FM and LM were predicted using validated equations and compared with dual-energy x-ray absorptiometry measurements in a subgroup. Adjusted Cox models were used to evaluate the associations of baseline and longitudinal changes in FM, LM, and WC over 1- and 4-year follow-up with risk of overall HF, HF with preserved ejection fraction (EF; EF ≥50%), HF with reduced EF (EF <50%), and MI. RESULTS: Among 5103 participants, there were 257 incident HF events over 12.4 years of follow-up. Predicted and measured FM/LM were highly correlated (R2=0.87-0.90; n=1369). FM and LM decreased over 4-year follow-up with greater declines in the intensive lifestyle intervention arm. In adjusted analysis, baseline body composition measures were not significantly associated with HF risk. Decline in FM and WC, but not LM, over 1 year were each significantly associated with lower risk of overall HF (adjusted hazard ratio per 10% decrease in FM, 0.80 [95% CI, 0.68-0.95]; adjusted hazard ratio per 10% decrease in WC, 0.77 [95% CI, 0.62-0.95]). Decline in FM was significantly associated with lower risk of both HF subtypes. In contrast, decline in WC was significantly associated with lower risk of HF with preserved EF but not HF with reduced EF. Similar patterns of association were observed for 4-year changes in body composition and HF risk. Longitudinal changes in body composition were not significantly associated with risk of MI. CONCLUSIONS: In adults with type 2 diabetes, a lifestyle intervention is associated with significant loss of FM and LM. Declines in FM and WC, but not LM, were each significantly associated with lower risk of HF but not MI. Furthermore, decline in WC was significantly associated with lower risk of HF with preserved EF but not HF with reduced EF.

Waist Circumference Change During Intensive Lifestyle Intervention and Cardiovascular Morbidity and Mortality in the Look AHEAD Trial.

OBJECTIVE: The Action for Health in Diabetes (Look AHEAD) trial was a randomized trial comparing effects of intensive lifestyle intervention (ILI) and diabetes support and education (DSE) on cardiovascular disease (CVD) among individuals with overweight/obesity and type 2 diabetes. A secondary analysis was conducted to evaluate the association between change in weight and waist circumference (WC) and CVD outcomes. METHODS: Participants (N = 5,490) were classified into four categories based on change in weight and WC between baseline and year 1 (both increased, both decreased, etc.). Separate Cox proportional hazards regression models were fit for ILI and DSE (using group that reduced weight/WC as reference), and time to first occurrence of primary and secondary CVD outcomes from year 1 through a median of almost 10 years were compared. Second, time to first event among all four ILI groups relative to DSE was evaluated. RESULTS: Within DSE, CVD outcomes did not differ. ILI participants with increased WC had increased risk of primary outcomes, regardless of weight loss (hazard ratio: 1.55 [95% CI: 1.11-2.17]) or weight gain (hazard ratio: 1.76 [95% CI: 1.07-2.89]), and had increased risk of secondary outcomes (overall P < 0.01) relative to ILI participants who reduced both weight and WC and relative to DSE participants. CONCLUSIONS: In this secondary analysis, increased WC during the first year of ILI, independent of weight change, was associated with higher risk for subsequent cardiovascular outcomes.

Body shape concerns across racial and ethnic groups among adults in the United States: More similarities than differences.

This study evaluated the relationship between race/ethnicity and body shape concerns among adults in the U.S. and evaluated if this relationship varied by Body Mass Index (BMI) and gender. Data were collected from U.S. adults (N = 2,212) using a national online survey panel designed to approximate the US census data. Gender, age, race/ethnicity, BMI and body shape concerns (Body Shape Questionnaire) were assessed. Analysis of variance was utilized to evaluate the race/ethnicity and BSQ association and if the relationship varied by gender and BMI category. The sample (65 % White, 13 % Black/African American, 16 % Latino/Hispanic/Mexican American and 6 % Asian/Pacific Islander) was 50 % female; mean age of 44.2 years (SD = 16.8); BMI of 27.4 (SD = 6.7). A gender by BMI category interaction (p < .01) revealed no difference in BSQ scores by gender when BMI < 18, but higher BSQ scores among women for all other BMI groups. A main effect of race/ethnicity revealed BSQ scores were equally high across racial/ethnic groups, except individuals who identified as White (M = 42.0, SD = 19.7) reported higher BSQ than those identified as Asian/Pacific Islander (M = 37.4, SD = 17.4). Body shape concerns are common among US adults. Individuals of racial/ethnic minority status may experience similar gender- and BMI-related differences in body shape concerns as White individuals.

Characterizing Lifetime and Daily Experiences of Weight Stigma among Sexual Minority Women with Overweight and Obesity: A Descriptive Study.

Sexual minority women are disproportionately impacted by obesity yet are underrepresented in weight stigma research. This Ecological Momentary Assessment (EMA) study is a secondary analysis that aimed to elucidate the frequency and contextual characteristics of perceived experiences of lifetime and momentary weight stigma among sexual minority women with overweight/obesity. Participants were 55 sexual minority women ages 18-60 with a body mass index ≥25 kg/m2. Perceived lifetime weight stigma events were assessed at baseline. For the subsequent five days, participants used a smartphone to complete five daily, random EMA prompts assessing the frequency/characteristics of perceived weight stigma events in daily life. All participants reported at least one lifetime weight stigma event. During the EMA period, participants reported 44 momentary weight stigma events (M = 0.80), with 24% of participants reporting at least one event. During most instances of weight stigma, women perceived the stigma's cause to be their weight and another minority identity (e.g., sexual orientation). Findings showing high rates of perceived lifetime weight stigma in this sample and frequent co-occurrence of perceived weight stigma with stigma due to other marginalized identities in daily life underscore the need for future, larger studies investigating weight stigma through an intersectional lens in sexual minority women with overweight/obesity.

The pain of weight-related stigma among women with overweight or obesity.

Pain is prevalent among individuals with overweight or obesity but few studies have examined the mechanism linking pain with excess body weight. Because there is evidence that social and physical pain may be processed through similar physiological mechanisms, weight-stigma may potentiate the experience of physical pain through shared neuroanatomical pathways. This study evaluated the relationship between perceived weight stigma and self-reported bodily pain in a sample of overweight and obese adult women. Sixty-one women with a body mass index (BMI) between 25-35 completed self-report questionnaires assessing perceived stigma, internalized weight stigma, and self-reported pain. Height and weight were measured and participants completed a demographic and health history questionnaire. Hierarchical regression analyses were utilized to predict self-reported pain from perceived stigma, adjusting for demographic variables associated with self-reported pain as well as pain-related conditions. Perceived stigma was associated with pain F(6, 54)=6.10, p<.001) as was internalized stigma. Perceived stigma mediated the relationship between BMI and bodily pain among individuals with a BMI in the overweight range but not among individuals with a BMI in the obese range. Weight-related stigma among women with overweight or obesity appears to be associated with greater experience of physical pain. These results underscore the need to evaluate multiple mechanisms that might explain the relationship between bodily pain and body weight and to determine how the relationship may vary across different subgroups of individuals.
