The Statistics
  • Poverty
  • Food Insecurity
  • Food Insecure with Hunger

What is obesity?
  • A nutritional disorder related to the increased
    consumption of energy dense (high fat, high
    sugar, high salt) processed foods and beverages
  • A lifestyle disorder in advanced economies and
    urbanising societies
  • A medical disorder associated with around 35
    diseases (e.g. Type II diabetes mellitus, severe
    osteoarthritis, hypertension, heart disease)

5
What is obesity? (cont)
  • Obesity is part of a new world-wide trend of
    chronic lifestyle-based non-communicable
    diseases (WHO). It is
  • Found in societies also suffering both food
    surplus and insufficiency
  • Has poor and expensive treatment implications
  • Requires whole-society preventive
    considerations similar in complexity and scope
    to those of drugs or HIV.

6
Inaction in the face of the obesity epidemic has
massive consequences for society to economic
efficiency and medical and human costs Geof
Rayner, PhD ICD 2004

Obesity Trends Among U.S. Adults between 1985 and
2002
  • Definitions
  • Obesity having a very high amount of body fat in
    relation to lean body mass, or Body Mass Index
    (BMI) of 30 or higher
  • Body Mass Index (BMI) a measure of an adults
    weight in relation to his or her height,
    specifically the adults weight in kilograms
    divided by the square of his or her height in
    meters

2001
  • Source of the data
  • The data shown in these maps were collected
    through CDCs Behavioral Risk Factor Surveillance
    System (BRFSS). Each year, state health
    departments use standard procedures to collect
    data through a series of monthly telephone
    interviews with U.S. adults

Obesity Trends Among U.S. Adults between 1985 and
2002
  • Source of the data
  • The data shown in these maps were collected
    through CDCs Behavioral Risk Factor Surveillance
    System (BRFSS). Each year, state health
    departments use standard procedures to collect
    data through a series of monthly telephone
    interviews with U.S. adults
  • Prevalence estimates generated for the maps may
    vary slightly from those generated for the states
    by BRFSS (http//aps.nccd.cdc.gov/brfss) as
    slightly different analytic methods are used.

29
CDC National Trends and Statistics 2002 (NHANES)
  • 21 Adults Obese
  • Over 60 overweight
  • 8,800,000 children 6-19yo Overweight or Obese
  • 1963-2000 changes
  • 6-11yo 4.2 15.3
  • 12-19yo 4.6 15.5

More Definitions
  • Food Insecurity
  • Hunger
  • FRAC definition of Hunger in America
  • Mild Malnutrition
  • Food Insufficiency
  • Food Security

31
  • Nutrition Security
  • Community Food Security
  • also ADA Definition
  • Food Restriction

32
Children Overweight vs. Obese
  • Term overweight is used to describe children in
    lieu of obese
  • 95th percentile is considered overweight
  • 85th percentile at risk for obesity

33
BMI
  • Overweight is defined as over 25 kg/m2
  • Not used consistently
  • Establish the benchmark in use when reading
    research.

34
The Food Security Model Survey Categorization
  • Food Secure
  • Food Insecure
  • Food Insecure with Hunger (mild/severe)

35
Food Security Measurement
  • National food security survey
  • Developed in early 1990s in response to National
    Nutrition Monitoring process
  • Core module consists of 18 scaled items
  • All items in context, because there was no
    money or stamps to buy food. Involuntary
    vs. voluntary food restriction.
  • Now included in
  • numerous state surveys including CA
  • national surveys (NHANES IV)
  • supplement to Current Population
    Survey since 1995

36
  • Questions Asked
  • Anxiety that the household budget is inadequate
    to buy enough food
  • Inadequacy in the quantity or quality
  • And instances of reduced food intake or
    consequences of reduced food intake for adults
    and for children.
  • Food Use

37
The Paradox
  • What actually is it?
  • High Prevalence of obese overweight
  • Low income Food Insecure
  • - Watch
  • Terminology
  • Data Sets
  • Keep trends in mind

38
  • Olsen et.al. in 1993 study Women
  • Female BMI significantly higher (P lt 0.05)
  • Food secure households 25.6
  • Food insecure households 28.2
  • 37 had BMIs in excess of 30

39
  • Basiotis LIno (2002)- Women
  • NHANES HEI
  • Women 19-55
  • Lower Diet Quality (HEI 58.8 vs 62.7)
  • BMI 25-30 Overweight food sufficient 42
  • BMI 25-30 Overweight food insufficient 58

40
  • Townsend et.al. - Adults/Women
  • CSFII
  • Overweight Defined at 27.3 vs. 25 (new standard)
  • Examination of Food Insecurity
  • Low income outcomes (excluding severely food
    insecure households)
  • Food Secure - 34 Overweight
  • Mildly Food Insecure - 42 Overweight
  • Moderately Food Insecure -52Overweight

41
Townsend Cont.
  • Food Stamp Recipient Outcomes
  • Food Secure 48.4
  • Mildly Food Insecure 53.7
  • Moderately Food Insecure 68.3
  • Food Insecurity a predictor of overweight and
    above the effect of income (P lt 0.0001)
  • Women significantly at risk and men not

42
The Food Stamp Component
  • Perez-Escamilla et al (2000)
  • When Food Stamps Last the Entire Month
  • Food Security greater
  • Food Insecurity lower
  • Possibility of Consistent Food Intake

43
  • Anand et.al. (1999) Children
  • Using NHANES (Food Insufficiency)
  • Higher parents BMI the higher the risk for their
    child
  • Positively Associated with Fat and Protein
  • Negatively Associated with Total Caloric Intake,
    but what is consumed is high fat
  • Avid TV watching (Safety/Society?)

44
Overweight Children
  • Children with overweight parents
  • 5x more likely to be overweight (Guo)
  • The higher the parents BMI
  • the greater the risk that the child will have a
    high BMI (Anand)

45
The Food Environment/Quality
  • Supersizing
  • Marketing
  • High Fat, High Sugar - often cheap
  • Bottle Feeding

46
The Living Environment
  • Television
  • Computers
  • Safety of Community

47
Bringing it All Together
48
  • Limitations of existing data
  • Sample size
  • Historically focus food insufficiency not food
    security
  • NHANES is family measure with the same values for
    children and adults

49
The Food Stamp Cycle Hypothesis
  • Townsend
  • Promotion of wt gain
  • (1-3 wks food secure period)
  • Binging possible
  • Promotion of wt loss
  • (3-4wks food insecure period)
  • Involuntary Restriction
  • Metabolic impact
  • Studies to date

50
Deterrents to Access
51
  • Food Access
  • Food Deserts
  • Equipment
  • Transportation
  • Elderly
  • Skills Education
  • Preparation
  • Media Literacy
  • Housing
  • Lack of affordable housing less funds for food

52
  • Unemployment
  • Lack of Education
  • Seasonal Employment
  • Changing Market Needs
  • Psychological Components
  • Depression
  • Stress

53
Immediate Actions
54
  • Significant Food Stamp outreach to eligible
    households
  • Enhanced transportation for low income and rural
    communities
  • Improved access to fresh fruits and vegetables

55
  • Support of both WIC and Senior Farmers Market
    Nutrition Programs
  • Incorporate Food Security Core Survey Module into
    clinical settings, and consider when making diet
    prescriptions
  • Encourage Breastfeeding Baby Friendly Hospital
    Initiative

56
  • Adequate funding for Child Nutrition Programs
  • Expansion and outreach for Child Nutrition
    Programs (assisting Summer Food Program sponsors,
    WIC, CACFP)
  • Incorporation of education component into Child
    Nutrition Reauthorization

57
Why Breastfeeding?
  • Breastfed Babies evidence of less weight gain
  • Higher insulin levels prolonged insulin
    response assoc w/weight gain
  • Higher levels of leptin
  • Breast fed babies may develop better internal
    cues stop feeding/eating when they are full vs.
    overfeeding that is associated with bottle
    feeding
  • Formula increases affinity for fatty and sweet
  • Made with sucrose (sweeter) vs. lactose

58
Long Term Barriers - Actions
  • Research we need more
  • Food Cycle Hypothesis
  • Studies of Food Insecure Populations
  • Federal Nutrition Programs need to examine
  • Policy
  • Purchasing
  • Preparation

59
Long Term Barriers - Actions (cont.)
  • Living Wage
  • Support of Child Care
  • Food stamp levels that ensure adequate nutrition.
  • More flexible rules to allow people on TANF to
    pursue education and job training.
  • Affordable housing opportunities.

60
Expanded Concept ofCommunity Food Security
61
  • Community Food Security
  • Community food security (CFS) is defined as a
    situation in which all community residents obtain
    a safe, culturally acceptable, nutritionally
    adequate diet through a sustainable food system
    that maximizes community self-reliance and social
    justice.
