Title: The Culture, Politics and Economics of Our Obesogenic Society
1The Culture, Politics and Economics of Our
Obesogenic Society How to Fix It
- Antronette K. Yancey, MD, MPH, FACPM
- Associate Professor,
- UCLA School of Public Health
2Summary Points
- Current strategies are not containing the obesity
and sedentariness epidemics - Need shift away from clinical view of obesity as
personal disorder requiring medical Rx - An ecological approach regards obesity as a
normal response to an abnormal environment,
rather than vice versa - Understanding, measuring, and altering the
obesogenic environment is criticalsociety has
key role in sharing, with individuals, the high
costs of healthy lifestyle change/maint.

22Excess physical environmental risk in underserved
communities
- targeted/exploitative marketing
- excess fast food outlets
- few supermarkets
- limited shelf choices
- high-fat food availability (home, church
- poorer public/less pvt transportation
- distance to private fitness facilities
- few worksite fitness opportunities
- few/poor neighborhood recreation facilities
- lesser neighborhood safety
- poorer public/less pvt transportation
23Excess economic environmental risk in underserved
communities
- low neighborhood demand for healthy food choices
- low family incomes
- other household expenses
- little homegrown food
- financial incentives for under-resourced schools
by commercial vendors
- limited investment in parks/rec facil.
- fitness facility fees
- cost of exercise equipment
- less stable employmt patterns
- fewer trained PE instructors
- large PE classes
- poorly equipped facil.
24Excess sociocultural environmental risk in
underserved communities
- traditional cuisine
- fasting-feasting
- prevalent obesity/norms
- body image
- female roles
- (perceived) food insecurity
- cultural attitudes about PA, rest
- fears about safety

LA County Adults
31Influence of Self-Perceived Weight Status on
PA, LA County Adults
- Across racial/ethnic groups, regardless of BMI,
those perceiving themselves as overweight more
sedentary than those with average wt.
self-perception (45 vs. 30) - Influence most pronounced for males and normal
weight individuals - In multivariate analysis, self-perceived
overweight, not BMI, predicts sedentary behavior
(OR1.40, CI 1.19, 1.64) - Yancey, Wold et al., in preparation, 2003
32A small behavior change over time can
create/prevent some weight problems.
33Population benefit estimates of risk factor
change weight
- Weight loss of 8-15 lbs or 5-10 would decrease
Type 2 diabetes risk by 30-60, without achieving
ideal body weight - Modest weight loss normalizes BP (Resnick et al.,
2000), elevates mood and relieves anxiety (Wadden
et al., 1996) - --5 reduction in SBP would reduce stroke
incidence by 30 (Law et al., 1991) - --2 decrease in DBP would decrease CHD risk by
6, stroke/TIA by 15 (Cook et al., 1995)
34Population benefit estimates of risk factor
change PA
- If the entire U.S. population increased its PA
level by 30 min. of brisk walking/day, colon CA
incidence would decrease by 15 (Colditz et al.,
1997), stomach CA by 5- to 6-fold (Terry et al.,
1998), and CHD risk by 30-40 in women (Manson et
al., 1999) - Maintenance of moderate PA is assoc. with a 1/3
to 2/3 lowering of Type 2 diabetes incidence over
4-14 yrs (Clark, 1997) - Type 2 diabetes risk was 50 lower among
individuals physically active at any level, and
66 lower among those at least moderately active
(James et al., 1998)
35Physical Fitness and Academic Performance
- The California Department of Education studied
353,000 fifth graders, 322,000 seventh graders,
and 279,000 ninth graders across the state to see
whether 2001 SAT-9 performance was related to
results of the state-mandated physical fitness
test (the Fitness-gram), measuring - Aerobic capacity
- Body fat composition
- Abdominal strength
- Trunk extension strength
- Upper body strength
- Flexibility.

41Effective Physical Activity Promotion
- Physical environmental change is not enough!
Social norms and values must also be addressed.
Unlike hunger, theres no inherent drive for
PAwe must make it easier to do it than not to do
it!!
42Effective Physical Activity Promotion
- Cultivation of role models in PA promotion
ideally to create enjoyable experience - Exercise skills demonstration
- Engaging, interactive leadership style
- Fostering interactions between audience members
- Modeling behaviors encouraging others
- Relevant characteristics, in addition to
ethnicity and gender, include weight status,
fitness level, agility, and age aspirational
inspirational role models NEEDED!

- CDC-funded Racial Ethnic Approaches to
Community Health mechanism to address ethnic
health disparities - 24 implementation phase projects nationally
- Community Health Councils, Inc., lead agency for
African Americans Building a Legacy of Health,
collaborates with 220 local agencies, CBOs, govt
entities, universities, and businesses on various
projects, to sponsor seminars for providers,
patient education workshops, office staff

HealthProcess evaluation
- Intervention Multi-component, centered around
modeling the behaviors promoted (walking the
talk)(1) incorporation of fitness breaks into
meetings, events and other gatherings, (2)
provision of wellness training focused on
changing the norms of organizations to
incorporate physical activity into their regular
conduct of business, (3) provision of a personal
training to CBO leaders, (4) development of a
small grants program to map enhance PA
opportunities
50African Americans Building a Legacy of
HealthProcess evaluation
- Measures Level of organizational support for
physical activity integration assessed by level
of commitment represented in interventions
selected Results Nearly half of the gt200
participating organizations demonstrated active
support for physical activity integration, with
gt25 committed at the highest level of support
51African Americans Building a Legacy of
HealthProcess evaluation
- Conclusions Broad capacity and support for
organizational integration of physical activity
was demonstrated, with level of commitment
varying by organization type. Similar to the
successful evolution of tobacco control,
organizational policies that incorporate physical
activity into the normal conduct of business
should be implemented and evaluated.

eating among staff - To provide skills and tools to influence staff to
promote physical activity healthy eating among
WIC clients/families
54California Fit WIC Staff Wellness Training
- Training sessions included
- Engagement around ubiquitous nature of the
problem (toxic environment surrounding us) - Skills training in workplace practice change
(e.g., movement breaks, walking mtgs, leading
co-workers to stairs vs. elev., healthy
refreshments identifying practical strategies
to integrate PA (parking farther away, walking
around childrens play area, carrying a basket
vs. pushing a grocery cart) - Empowerment thru provision of tools, e.g.,
videos, audiotapes, exercise bands, pedom.

categorized PA levels tended to be more
correlated with PA stage of change (r.42)
compared with controls (r.28, z1.41, p.16)

break made them feel better about their jobs - Mirrors data from worksite PA prom. studies
demonstrating improved employee productivity
morale
69LAC Fitness Wellness StudyConclusions
- Captive sedentary, overweight audiences may be
engaged in brief bouts of PA as a part of the
workday, regardless of stage of change - PA experience decreases sedentary individuals
satisfaction with their suboptimal fitness levels
and, perhaps, their over-estimation of their own
PA participation - Organizational practices that incorporate PA into
the normal conduct of business should be
implemented and evaluated

73Community Steps to Minority Youth Fitness
- NICHHD-funded R01, part of NIH Innovative
Approaches to Prevention of Obesity Initiative
74METHODS
- Sixth-grade students from a randomly assigned
southern Los Angeles middle school were recruited
for a 10-week in-school nutrition/ physical
activity program replacing standard PE classes.
75METHODS
- Sixth-grade students from a second middle school,
matched for ethnic and SES status, were recruited
as a control group. They participated in the
standard PE curriculum.
76CHALLENGES
- 6th grade enrollment in intervention site
increased by 50 (from 600 to 900 students)
between conduct of pilot and full study
implementationextending t devoted to roll call
clothes change - Intervention site was named one of four
under-performing schools threatened with state
administrative take-over
77RESULTS
- Baseline sample (n226)
- Gender Female124 (54.9)
- Ethnicity
- Latino/Hispanic122 (54)
- African American 88 (38.9)
- Caucasian 0
- Asian American 2 (0.9)
- Native American 2 (0.9)
- Biracial 9 (4.0)
- Other 3 (1.3)
78RESULTS
- Using revised CDC guidelines for BMI
classification, 52.8 (n105) were normal weight,
15.6 (n31) were at risk for becoming
overweight, and 31.7 (n63) were overweight. - Serum cholesterol levels were elevated among
46.4 of the students.
79Preliminary InterventionRESULTS
80CONCLUSIONS
- Pre-adolescent ethnic minority students already
manifest health complications associated with
poor eating habits fitness, including obesity,
elev. BP hyperlipidemia. - Elevated systolic BP, but not Chl, shows positive
linear correlation with BMI. - Age-related declines in fruit, juice and
vegetable consumption, but not weight or fitness,
may be decreased by low-intensity, intervention
in low-resource school environment.
81Community Cost-Sharing
- 1. Leveraging funding agency role to
- mandate healthy/fit workplace practices, with
added resource allocation (e.g., 5) - ensure that a majority of intervention models
include a structural (environmental) change
component and are developed and tested in
ethnically diverse, non-affluent settings - 2. Changing internal organizational culture
(social norms) to create healthy/fit foundation
workplaces (Walk the Talk)
82Community Cost-Sharing(cont.)
- 3. Modeling recommended behaviors in regularly
scheduled public (televised) private meetings
and events, e.g., staff meetings, school board
hearings, city council meetings, state
legislative sessions, gospel choir rehearsals,
adult evening classes, pot lucks, middle school
home room periods, press conferences - Example Culver City provides 60 min./wk (20
min. on 3 days) of work time for PA breaks - Example REACH project-- gt100 CBOs actively
incorporated PA breaks into mtgs/events
83Govt Cost-Sharing(cont.)
- VISION Employees feel the same sense of
entitlement to exercise breaks on company time
as breaks for smoking or coffee - MODEL Smokefree workplace practices, often
mandated by funding agencies, pre-dated
legislative policy smokefree workplace mandates
84Community Cost-Sharing(cont.)
- BOTTOM LINE Actively engaging decision-makers,
opinion leaders, service providers gatekeepers
in healthy lifestyle change is critical to their
prioritizing these issues (a) in creating the
social momentum/political will for legislative
policy change and (b) in their professional and
personal governance of youth activities.
