Availability of Healthy Foods in Baltimore: Associations with Diet Quality and BMI Manuel Franco MD, PhD CLF Innovation Grant 2006 Johns Hopkins Bloomberg School of Public Health Department of Epidemiology
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 • 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
Data Collection: May – July 2006 • 226 food stores completed in 159 neighborhoods • Supermarkets (41), Grocery stores (110), Convenience stores (54), Behind glass stores (21) • Original list: 365 • Misclassified: 130 (34%) • Refusals : 21 (8%) • New Stores : 12 • Data Collectors: Amanda Rosecrans, Brooke Mickle, Gila Neta, Krissett Loya
Grocery Store in West Baltimore 83 MESA participants within 1 mile
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 • “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
Availability of healthy foods and neighborhoods’ racial composition 159 contiguous census tracts and the 226 food stores located within them
Availability of healthy foods in Baltimore neighborhoods by racial compositions **P<0.001, compared to predominantly white neighborhoods
Means and 95 % CI of dietary patterns by availability of healthy foods assessments Dietary patterns scores ** P for trend < 0.05
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)
