Healthy Foods, Diet Quality and Obesity
  • 2005 Dietary Guidelines:
    • A variety of fruits and vegetables
    • Whole grains
    • Fat-free or low-fat milk
  • Prevention of obesity, diabetes and heart disease
  • Large racial and economic health disparities
  • Hypotheses: Disparities in the availability of healthy foods exist. Availability of healthy foods relates to the quality of diet and body weight
specific aims
Specific Aims
  • Aim 1
  • Investigate the association of neighborhood availability of healthy foods with racial and income composition of 159 neighborhoods in Baltimore
  • Aim 2
  • Investigate the cross-sectional association
  • between availability of healthy foods of 749 individuals’
  • and their diet quality and BMI

slide10

Availability of Healthy Foods in the Baltimore MESA participants

  • 749 men and women, free of CVD, 45 – 84 years
  • 159 Baltimore census tracts
  • For each participant we built 3 complementary measures of availability:
    • Neighborhood = mean stores HFAI in CT
    • Closest Store = HFAI closest store
    • Availability in 1 mile radius
dietary patterns and bmi
Dietary Patterns and BMI
  • “Fats and processed meats” pattern: high consumption of “fats and oils,” “high-fat and processed meats,” “fried potatoes”
  • “Whole grains and fruit” pattern: high consumption of whole-grain bread, fruit and low fat milk
  • Weight and height measured using valid tools and following a standard protocol. (BMI) = Kg/m2

policy implications and following steps
Policy Implications and following steps
  • Support existing stores in inner city neighborhoods
  • Encourage the distribution of locally farmed fruits and vegetables to improve the HFAI in Baltimore stores
  • Collaboration with Baltimore City Health Department and Urban Planning Department
  • 2009 CLF Report: Food Environment in Baltimore
  • First city to have a full map of food stores (Data collection currently ongoing)
