Outputs
OUTPUTS: The goal of the study was to examine the prevalence and factors influencing the intrafamilial obesity among Native Americans and Goals and objectives of the project: African Americans of Oklahoma. The objectives of the study were: a) to identify the patterns across the generations that may influence the childhood obesity. b)to determine the factors that influence childhood obesity such as diet, physical activity and life style. c)to determine the relationship between nutritional status and ethnicity with insulin, leptin, growth hormone and blood lipid profile and glucose concentration within the cohorts in the study. The data collected and analyzed by Dr. Knight and Dr. Spicer during the study period from September 2001 to 2003 indicates that 90%of African American and 89% of Native American parents and grand parents had body mass index greater than 25.0. 42% of African American and 61% of Native Americans children had BMI greater than 85th percentile. Leptin, waist
circumference and blood pressure among African American and Native American women of child bearing age shows that 99% of women were overweight, to obese with a mean BMI of 37 + or minus 7. 58% of Native American and 61% of African American women were obese. The African American women had greater plasma leptin concentration and greater upper arm adipose tissue than Native American women. The Native American women had higher blood glucose level and triglyceride concentrations. The Native American women in this study may have been more sensitive to insulin resistance and were at risk for metabolic syndrome. Further data analysis on life style and dietary factors indicate that all diets were inadequate in fruits, vegetables and milk and also high in total energy fat energy and servings of fats and sugar. The findings indicate that a community based culturally sensitive intervention programs are needed to reduce the incidence of childhood obesity in Oklahoma.
PARTICIPANTS: 88 Families.
Impacts
This project resulted in One Publication, 2 masters, thesis and a creative component for Masters thesis. It also helped to establish a working relationship with Oklahoma State University. It helped Langston to establish a human nutrition research and expose the students different aspects of research.

Progress 01/01/03 to 12/31/03
Outputs
The objective of this study is to examine the prevalence of overweight and obesity among Native and African American children, parents, and grandparents. Also, to examine obesity-related factors, including: diet, physical activity, sedentary behaviors and biochemical values. To date, all data has been collected and partially analyzed. One manuscript is under review and two more manuscripts are in the final stages of development before submission to appropriate journals.
Impacts
Currently there is a lack of population data regarding familial as it relates to overweight/obesity, diet, physical activity and sedentary behaviors. This information can be used to develop effective culturally appropriate interventions to improve diet and physical activity levels and reduce overweight and television viewing in these ethnic groups, particularly for children.

Progress 01/01/02 to 12/31/02
Outputs
The objective of this study is to examine the prevalance of obesity among Native American and African American children, a parent and a grandparent. The study also examines obesity-related factors, including: diet, physical activity, sedentary behaviors and education levels. To date, all data has been collected, entered into a computer database and data is currently being thoroughly checked. Statistical analysis began in February 2003 and is ongoing. Two abstracts from the research project have been developed and submitted. The investigators are currently working on a total of 6 articles to be submitted for publication sometime in the summer of 2003. A follow-up grant proposal has been written by the project manager and will be finalized and submitted to USDA in fall of 2003.
Impacts
Currently there is a crucial need for data that support a variety of culturally appropriate nutrition education interventions to address obesity prevention and innovative methods to improve the overall dietary consumption and physical activity patterns among Native Americans and African Americans.
