Physical Activity and Nutrition (PAN) Epidemiology
The aim of the MDHHS Physical Activity and Nutrition (PAN) Program is to prevent and control obesity and other chronic diseases through healthful eating and physical activity.
The physical activity and nutrition epidemiologist supports the PAN Program by monitoring trends in weight status, nutrition quality and access, and physical activity levels among youth and adults in Michigan. In addition, breastfeeding practices of new mothers are followed over time. Surveillance is also conducted to track disparities in health and behavior by race/ethnicity, socioeconomic status, geography, gender, age, disability status, and other factors.
If you are looking for specific physical activity and nutrition surveillance data that you do not see here, or if you need accessibility assistance reading any of the documents on this webpage, please contact the MDHHS Chronic Disease Epidemiology Section at MDHHS-ChronicEPI@michigan.gov.
