The Dietary Guidelines for Americans provide recommendations for making better food and physical activity choices that promote health and help prevent disease. The Healthy Eating and Lifestyle for Total Health (HEALTH) Study is a multi-site study with two primary objectives. The first objective is to identify reasons why adults and children from major U.S. racial/ethnic groups may or may not follow the Dietary Guidelines for Americans. The second objective is to examine these influences and other factors as they relate to dietary behavior and body mass index (BMI) by administering surveys across the U.S. population served by USDA Human Nutrition Research sites.

Eligible participants will be 5th grade students or their adult caregiver who attend public school districts in the Lower Mississippi Delta of Arkansas, Louisiana and Mississippi.  Eligible adult participants are defined as the person responsible for food preparation most days of the week for a 5th grade child.  

Delta OPRU is responsible for the collection of information on African-American eligible participants. The study will collect data using cognitive interviews and the Nominal Group Technique (NGT).  Cognitive interviews will be conducted to develop/refine questions to be used in the NGT sessions.   The Nominal Group Technique involves informal group discussions pertaining to diet, exercise and general health in order to identify barriers and facilitators to Dietary Guideline adherence. 

HEALTH Ancillary Study

Delta OPRU will be expanding the data collection to African Americans and Caucasian Americans throughout the Lower Mississippi Delta of Arkansas, Louisiana and Mississippi.
