DYNAMIC ASSESSMENT OF OBESITY STIGMATIZATION Jason D. Seacat, Ph.D. Department of Psychology, Western New England University Overview Part 1: Obesity Overview Define and discuss obesity and trends in US Obesity stigmatization Consequences of obesity stigmatization Part 2: Assessment of Stigmatization Daily diary assessment of stigmatization Preliminary Laboratory research findings assessment of stigmatization effects Triangulating assessment strategies Part I: Operational Definitions Operational Definitions (CDC Body Mass Index) Overweight ≥ 25 Obesity ≥ 30 Morbid Obesity ≥ 40-44.9 Super Morbid Obesity ≥ 45 Assessment of Obesity Status BMI Body Fat % Scales (e.g., Tanita) Skin fold thickness Bioelectric impedance assay Obesity Trends-Adults Prevalence of Overweight/Obese in the United States Despite increasing awareness, education and intervention the obesity epidemic continues to intensify 36% of adults are overweight 34% of adults are obese (Flegal et al., 2008) U.S. Trends and Projections National Health and Nutrition Survey U.S. Disparities Racial/Ethnic Disparity of Obesity Non-Hispanic Black- 44% Mexican American- 39.3% All Hispanic- 37.9% Caucasian- 32.6% Geographic Disparity South- 29.4% Midwest- 28.7% Northeast- 24.9% West- 24.1% CDC, 2011 Consequences of Obesity Physical Health Consequences Coronary Heart Disease/Stroke Type II Diabetes Hypertension Certain Cancers (e.g., endometrial, colorectal) Osteoarthritis Economic Consequences Medical costs alone associated with obesity $147 Billion (Finkelstein, 2009) Consequences of Obesity Social Consequences Obesity stigmatization According to Puhl and Heuer (2009), obesity “remains one of the last acceptable targets of stigma/discrimination” Despite increasing rates of obesity, obesity stigmatization is also increasing Obesity Stigmatization Rates of obesity stigmatization have increased by 66% since 1995 (Schvey, Puhl & Brownell, 2011) More than 70% of overweight/obese individuals now report frequent stigmatization Obesity stigmatization occurs in ALL life domains While both sexes encounter weight stigma, women are more frequently targeted than men Women may also be more susceptible to negative consequences of stigma due to gender-based attractiveness norms Types of Obesity Stigma Direct- (Institutional & Interpersonal) (e.g., bullying, denial of housing, workplace harassment, relationship abuse, ostracizing of obese individuals) Indirect- (Perceived) Individual perceptions of stigma and/or internalization of stigma Indirect stigma may actually be more potent than direct as it operates independently of actual occurrences Researchers need to assess both direct and indirect forms of stigmatization Consequences of Obesity Stigma Though consequences of stigma are individualized there are several commonly reported outcomes, including: Lack of access/opportunity Psychological/emotional trauma Social isolation Delay/avoidance of medical treatment Avoidance of healthy behaviors (e.g., exercise, compensatory eating) (Seacat & Mickelson, 2009; Vartanian & Colleagues, 2011) Perpetuation and exacerbation of obesity status** Assessing Obesity Stigmatization Existing stigma studies indicate that experiences with obesity stigma range from a low of 1 time per month to a high of 1-2 times per week (19992011) Most commonly experienced stigmatizing situations include (Sarwer et al., 2008) Nasty comments from children Nasty comments from family members Inappropriate comments from health care personnel Encountering physical barriers Limitations Existing stigma studies have widely employed crosssectional and retrospective assessments spanning up to 30 years or more in lifetime Memory erosion “Repression” of traumatic or painful events Underestimation of event frequency Limited ability to capture relationships between obesity stigma and actual health behavior (exercise/diet) Focus on “clinical” populations Hypotheses H1) Rates of obesity stigma will be higher than previous retrospective reports H2) BMI status will be positively correlated with obesity stigma H3) Levels of obesity stigma will be inversely related to participants’ average amount of exercise (in minutes) H4) Levels of obesity stigma will be inversely correlated with participants’ perceptions of the “healthfulness” of their daily diet Daily Diary Assessment of Stigma Seacat & Dougal (2011; In Prep) sought to test hypotheses and address limitations with a daily diary assessment study of obesity stigmatization Participants 50 overweight-obese women Aged 19-61 (M = 37.90) BMI 25.00-77.90 (M = 42.56) 42% Married 90% Caucasian 60% college educated (2yr-Completion of Grad Sch.) Daily Diary Assessment Procedure Approved by IRB, WNE Study was advertised on weight-related websites and blogs (e.g., Obesity Forum, Biggest Loser, My Big Fat Blog) Participants completed a baseline demographic survey and a daily diary assessment for a period of 7 days All participants were eligible for a raffle drawing for one of five $50 Visa check cards Daily Diary Assessment Measures Stigmatizing Situations Questionnaire (Myers and Rosen, 1999) (modified) 50 items/11 sub-scales Comments from children Comments from family Isolation, feeling ignored Barriers in environment Daily exercise/dietary habits Daily activities/places visited Daily interpersonal interactions Daily media consumption habits Preliminary Findings Hypothesis 1: Previous accounts using SSQ: 1x month to 2 x week Current participants reported a range of 2.74-5.24 stigmatizing events per day We also added open-ended stigma questions for participants to respond to. Many novel events emerged, that were not captured by the SSQ “I walked outdoors today and felt embarrassed to walk for a short time on the highway, where people who knew me might see me. I thought they would assume my car broke down, and not that I was exercising.” Preliminary Findings- Open Ended “[ I was ] with friends at a baby shower today so I went to McDonalds first so people wouldn't look at me eating more than I should” “The dentist was worried I might break his chair” “An old friend saw me and yelled "I didn't know you were pregnant” “While outside, some of the people that drove by seemed to do the "heavy-person double take look" as they passed by” Preliminary Findings-Open Ended “I was told that I was a bad mother because I can't set limits as to what my son or his friends eat during sleepovers, because I can't even control myself” “My ex-boss looked at me several times in a restaurant but acted like he didn't know me. I worked for him for 5 years but he always hated fat people” Preliminary Findings Hypothesis 2: Consistent with existing research and our current hypothesis, there was a significant and positive correlation between BMI and levels of reported obesity stigma (r = .58; p < .001) Preliminary Findings Hypothesis 3: Supporting our hypothesis, levels of obesity stigma were inversely correlated with participants’ average duration of daily exercise (in minutes) ( r = -.323; p =.008) Hypothesis 4: Contrary to our predictions, levels of obesity stigma were not significantly correlated with participants’ perceptions of daily dietary habits ( r = -.03; p = .84) Limitations Participant attrition Reliance upon self-report data Daily assessment may have “sensitized” participants to perceive events they typically would not have Lack of additional assessment methods to corroborate exercise/dietary data Pedometers Diet log Discussion Obesity stigma likely occurring at significantly higher rates than previously demonstrated Stigma increases in frequency as obesity status increases Stigma is significantly and negatively correlated with duration of physical activity in daily life Stigma was not significantly correlated with perceptions of diet Additional Work Dataset also contains detailed accounts of participants’ daily interpersonal interactions, activities, places visited and media consumption habits Next steps will be to analyze these data in conjunction with 11 subscales of SSQ to determine whether significant relationships exist Develop briefer version of SSQ for repeated use on the basis of current participant response patterns Future Directions Inclusion of direct measures of physiological reactivity and exercise/diet into daily diary assessment Reactivity Ambulatory BP monitors Momentary data capture devices Exercise Exercise/diet Pedometer log Laboratory Assessment of Obesity Stigmatization Researchers are now beginning to focus more intently on direct, physiological assessment of responses to obesity stigmatization R.

Hypothesized that encounters with stigma should produce detectable CNS and cardiovascular reactivity Laboratory Assessment of Stigma Though proposed, empirical relationship between obesity stigma and reactivity is yet to be established Majority of obesity stigma is subtle thus reactivity is likely variable and may be limited May produce frequent, low level activation of CNS and cardiovascular system Over time, repeated arousal may contribute to cumulative stress effects Micro-Stressor Effects Short-term effects- unknown Cumulative effects- theoretical Cardiovascular reactivity Exacerbated cardiac response Increased recovery time from stressors Potential Excess CNS Effects- cortisol production Adiposity Current Work Pilot testing a time series trial to assess cardiovascular and HPA activation to subtle stigmabased stressors 40 minute protocol Sex-based academic stigma in Math (St Threat Paradigm) 2x2x2 experimental design Prime-Negative-Male/Female Prime-Boost-Male/Female Neutral-Male/Female Current Work Intra-individual assessment BP, heart rate recorded at baseline and every four minutes Salivary cortisol recorded at baseline and in 8 minute increments thereafter Self-report at conclusion of assessment Restrictions: No caffeine, no nicotine, no exercise w/in 24hrs No food/tooth brushing within 6 hours Control for: Time of day, Med use (BP elevating, saliva diminishing, cortisol modulating) Conclusion Obesity and obesity stigmatization are increasingly prevalent in society Obesity stigma may contribute to perpetuation of obesity epidemic and to morbidity with other health conditions Assessment of experiences with and consequences of obesity stigmatization is in very early stages Methods to triangulate data are most widely accepted (and funded) Acknowledgements Western New England University, Faculty Development Grants 2010, 2011 Dr. Sheri Tershner, Director, Neuroscience Program Dr. Judy Cezeaux, Chair, Biomedical Engineering WNE Students: Sarah Dougal, Cory Saucier, Aaron Krause, Christina Barbarisi and others…
