Question: How do we decrease obesity? Clinic 1 v 1 Populations vs.
5
Why? If rising OW/OB trends continue, by 2030 it will reach
Unhealthy Weight Gain Obesity “Toxic” Obesity = Metabolic Syndrome (MetS) If rising OW/OB trends continue, by 2030 it will reach 16-18% of total health-care costs in the United States. (Wang, Beydoun, Liang, Caballero, Kumanyika, 2008) Currently, the world’s leading causes of death are the Atherosclerosis-related dz: Ischemic heart disease (IHD) Stroke (Lopez & Mathers, 2006; Mathers et al., 2009). OW/OB Increases Risk Factors Risk Factors Atherosclerosis Atherosclerosis begins at a young age Cardiovascular Dz (CVD) = Death
6
Goal Provide how-to-steps on how to move the needle on obesity &
prevent premature death from cardiovascular disease.
7
Outline WHY should we care? Metabolic Syndrome, CVD, etc!
Ok, we care. Let’s take action! Let’s Design an intervention that works (review the lit reviews) WHEN = Molten Moment WHERE = Clinic vs. Community WHAT WORKS?* *Informed by Biology The Story of the Fat Cell

Finished w/ Linear Growth
The Story of The Fat Cell Very High Risk of Future CVD Trajectory above the 75th percentile Ventura, Loken, & Birch (2009) Link between Childhood BMI and adult CV death Begins as early as: 8 yo in boys 13 yo in girls BMI child CIMT adult. Further adjustment for adult cardiovascular risk factors did not change the relationship (linear regression coefficient=2.1 microm/s.d.; 95% CI: 1.0; 3.1) between adult (28 yo) CIMT and adolescent BMI. Adjustment for adult BMI attenuated the association (linear regression coefficient=0.9 microm/s.d.; 95% CI: -0.3; 2.2) as the majority of overweight and obese adolescents remained overweight or became obese young adults. (Oren et al., 2003). Elevated BMI in boys as early as 8 and girls as early as 13 is significantly associated with developing metabolic syndrome at >or=30 years. OR y/o males 1.8 (1.3, % CI) and females 2.8 (1.9 to 4 95% CI). However, “elevated” BMI is along the 75th%ile of boys’ CDC chart and girls th percentile…. much much lower than the Expert Committee cutoffs. (Sun, Liang, Huang, Daniels, et al 2008) Denmark: Childhood BMI (7-13 y/o boys, y/o girls) is associated with adult CHD (a fatal or nonfatal event) (adult >=25 y/o). As BMI increased, the risk increased. Each 1 unit increase in BMI (5.6 kg (12.3 lbs) boys, 6.3 kg (13.9 lbs) girls) increased the risk for fatal cardiac events with a hazards ratio adjustede for bw, in 13 y/o boys (HR 1.24) and girls (HR 1.23) (Baker, Olsen, Sørensen, 2007). BMI at 13 y/o predicts cholesterol and glucose resistance in adulthood (Steinberger, Moran, Hong 2001) ‘Overweight’ in adolescents (13-18 y/o) predicts CHD morbidity in men and women (Must, Jacques, Dallal, Bajema, Dietz,1992). Harvard Longitudinal Study to Overweight=”75th percentile in subjects of the same age and sex in a large national survey” ‘Overweight; in adolescents (13-18 y/o) predicts mortality in men (not women): RR of 1.8 for all-cause mortality and 2.3 RR for CHD mortality. (Must, Jacques, Dallal, Bajema, Dietz, 1992). Harvard Longitudinal Study to Overweight=”75th percentile in subjects of the same age and sex in a large national survey” Norway: 227, y/o followed for 31.5 years. Increased risk of mortality became apparent after the age of 30. (Engeland, Bjorge, Sogaard, Tverdal 2003) - Mortality in males (vs. 25th-75%iles CDC charts): -85-95% 30% increased risk ->95% 80% increased risk - Mortality in females ->95% 100% increased risk White-black cohort of Bogalusa Heart Study y/o Srinivasan SR, Bao W, Wattigney WA, Berenson GS. Teenage OW (BMI>=75%ile (as compared to 25-50th%ile)) increases risk of adulthood(27 to 31 y/o): - Hypertension: Prevalence increased 8.5-fold - Dislipidemia: Prevalence increased 3.1 to 8.3-fold Finished w/ Linear Growth Increased BMI = Increased Risk of CVD CVD Risk: Sun et al., 2008 Trajectory: Ventura, Loken, & Birch, 2009

DECREASE Mortality risk in adulthood for OW/OB adolescents
If OW/OB teen Normal Weight by adulthood Risk Factors & Atherosclerosis associated with adiposity DECREASE (Oren et al., 2003; Weiss et al., 2009) But our patient has a 92% chance of remaining obese at the age of 40. (Nader, 2008) Trajectory above the 75th percentile Ventura, Loken, & Birch (2009) Link between Childhood BMI and adult CV death Begins as early as: 8 yo in boys 13 yo in girls BMI child CIMT adult.
