Obesity: Medical and Financial Consequences
• Medical Comorbidities– Coronary heart disease – Type 2 diabetes – Cancers (endometrial, breast, and colon) – Hypertension – Dyslipidemia– Stroke – Liver and Gallbladder disease – Sleep apnea and respiratory problems – Gynecological problems (abnormal menses, infertility)– Pain conditions
• Medical Expenditures– $147 billion in 2008 (Finkelstein et al., 2009)

What about obesity and mental health?
Allison et al., 2009; Dickerson et al., 2006
• Individuals with serious mental illness (SMI) have an extremely high prevalence of obesity• Nearly twice that
of the overall population
![Page 8: Sept 25, 2013 Integrated Care Conference](https://reader035.fdocuments.net/reader035/viewer/2022070501/5681693e550346895de0bb95/html5/thumbnails/8.jpg)
Obesity and Mental Health
• Those with SMI have increased weight-related conditions
• Mortality rates are 2-3 times higher in SMI as compared to the overall population
Bresee et al., 2010; Carney et al., 2006; Himelhoch et al., 2004
![Page 9: Sept 25, 2013 Integrated Care Conference](https://reader035.fdocuments.net/reader035/viewer/2022070501/5681693e550346895de0bb95/html5/thumbnails/9.jpg)
Causes of Obesity in SMI?
• Less active than the general population• Dietary behaviors in comparison to general
population:– Higher fat intake– Less fruits and vegetables– Higher overall caloric intake
• Medication side effects• Psychological factors/comorbidities
Amani, 2007; Compton et al., 2006; Daumit et al. 2004; Jerome et al., 2009; McCreadie, 2003; Strassnig et al., 2003

Psychiatric Disorders Associated with Obesity
• Binge Eating Disorder (BED)– recurring episodes of eating significantly
more food in a short period of time than most people would eat under similar circumstances, with episodes marked by feelings of lack of control. • eating quickly, often in absence of hunger;
feelings of guilt, embarrassment, or disgust, binge eating alone to hide the behavior; marked distress
– occurs, on average, at least once a week over three months. APA, DSM-5

Psychiatric Conditions Associated with Obesity
• Night Eating Syndrome (NES)–evening hyperphagia (ingestion of at
least 25% of daily calories after supper)
–awakenings with ingestions at least three times a week • awareness and recall of the eating • associated with significant distress
and/or impairment in functioning Stunkard, 2008

Dietary Approaches to Lifestyle Modification
Calorie Deficit ~1200-2000 kcal/d
Dietary Approaches:Low-fatLow-carbohydrateMediterranean Low-glycemic loadPortion-controlled diets
![Page 15: Sept 25, 2013 Integrated Care Conference](https://reader035.fdocuments.net/reader035/viewer/2022070501/5681693e550346895de0bb95/html5/thumbnails/15.jpg)
Increasing Physical Activity
> 180 m/wk MVPA for weight loss Must also include caloric restrictionAssociated with a number of health improvements,
independent of weight lossCan be performed in short boutsIncreasing other lifestyle activities is also effective
> 2000 steps for weight loss; > 6000 to avoid regainCritical for long-term weight loss maintenance
~ 60 m/d MVPA
![Page 16: Sept 25, 2013 Integrated Care Conference](https://reader035.fdocuments.net/reader035/viewer/2022070501/5681693e550346895de0bb95/html5/thumbnails/16.jpg)
Lifestyle Modification Interventions for Obesity
•Self-monitoring•Goal Setting•Stimulus control•Problem solving
• Increase self-efficacy and social support
• Relapse Prevention
![Page 17: Sept 25, 2013 Integrated Care Conference](https://reader035.fdocuments.net/reader035/viewer/2022070501/5681693e550346895de0bb95/html5/thumbnails/17.jpg)
Short-Term Outcomes
• Lifestyle modification programs typically produce 7 to 10% reduction in initial weight in 6 months
• Generally sustained at one year with ongoing, regular maintenance therapy
![Page 18: Sept 25, 2013 Integrated Care Conference](https://reader035.fdocuments.net/reader035/viewer/2022070501/5681693e550346895de0bb95/html5/thumbnails/18.jpg)
Weight Loss Maintenance
• Patients gain ~ 1/3 of their lost weight in the year following treatment
• Nearly half return to their original weight within 5 yrs
• 1:6 adults accomplish > 1 yr of maintaining > 10% of IBW
• Weight loss maintenance interventions can decrease the chance of weight regain

Adding cognitive therapy to standard treatment is associated with less relapse in obesity
Werrij et al., 2009
![Page 23: Sept 25, 2013 Integrated Care Conference](https://reader035.fdocuments.net/reader035/viewer/2022070501/5681693e550346895de0bb95/html5/thumbnails/23.jpg)
What is Cognitive-BehavioralTreatment of Obesity
– Assigns central importance to cognitive processes that maintain a problem
– For lasting change to occur, maintaining mechanisms need to be modified
– Utilize cognitive and behavioral procedures to change the maintaining mechanisms• Primary aim is to produce cognitive change• Behavioral experiments and cognitive restructuring
are central
Cooper, Fairburn & Hawker, 2003
![Page 24: Sept 25, 2013 Integrated Care Conference](https://reader035.fdocuments.net/reader035/viewer/2022070501/5681693e550346895de0bb95/html5/thumbnails/24.jpg)
Assess
• Motivation:– How are weight, dietary behaviors, and inactivity
interfering with:• What patient wants to do? How patient feels?
Health?
• History• Current Behavior:
– Dietary and PA Assessment– Logs
• Pros and cons of treatment; potential barriers; strengths; support; expectations

Circumstances
• Who am I with?• What am I thinking?• What is going on?• What do I really want right now? • Where am I and how do I feel about this place? • When am I eating? You should be recording the date and time in the
appropriate section, but here you can record more detail about what is going on. (I am eating when everyone else goes to bed)
• Why am I eating? • How am I feeling physically? (I am in pain, I am tired) emotionally?
(Do any of these words apply at the time of or right before this meal: bored, depressed, lonely, anxious, angry, guilty?)
![Page 28: Sept 25, 2013 Integrated Care Conference](https://reader035.fdocuments.net/reader035/viewer/2022070501/5681693e550346895de0bb95/html5/thumbnails/28.jpg)
Self-monitoring
• To weigh or not to weigh?
• Calories vs. no calories• Behaviors vs. calories• Provide an instruction
sheet– Portions, etc.
• When to introduce “circumstances”
• Meals in brackets.• Include start and stop time of meal.• State simply the foods or beverages you
consumed. • As much as possible, include portions. For
example, if you have pizza include number of slices or state if something was a pre-portioned meal (e.g., Lean Cuisine). Often labeling of a product will give information about what the manufacturer considers a serving size for that particular food.
• It is fine to use terms like “1 handful”, “2 serving spoons”, or “the size of a deck of cards” to estimate portions.
• Include both caloric and non-caloric beverages. • Include whether you are using a low-fat version
of a particular fool (e.g., skim milk)• Try to also record condiments like mayo or
sugar packets.

Regulate Eating Schedule
• No skipping meals– 3 meals vs. 3 meals/2 snacks vs. 6 smaller
meals• Eat breakfast• Eat around same time every day

Conclusions
• Obesity is a serious pubic health problem, particularly among those with SMI
• Lifestyle Modification is the cornerstone of all obesity treatments
• Cognitive-behavioral therapy can help with more sustained change
