Norman K. Pollock, PhD

FACULTY, GEORGIA PREVENTION INSTITUTE
Associate Professor of the Department of Pediatrics, Physiology and Graduate Studies

Contact Information 

Dr. Pollock is a nutritionist and bone biologist whose research studies pertain to childhood growth and nutrition, body composition, skeletal metabolism, and bone mineral accretion and structural development across the lifespan.  The major focus of his research is to determine how adipose tissue and bone interact to affect energy regulation, emphasizing factors such as diet, metabolic diseases, and hormonal imbalances that are associated with both obesity and poor skeletal health.

Research Interests

Dr. Norman Pollock is an Associate Professor of Pediatrics at Augusta University's Medical College of Georgia. He has training in the fields of clinical nutrition, bone biology, endocrinology, and biostatistics. Dr. Pollock has clinical trial experience conducting dietary and exercise interventions in children and adults at risk for cardiovascular disease and diabetes. His research interest are related to how fat and bone metabolism affect energy regulation, emphasizing on factors such as diet, physical inactivity, metabolic diseases, hormonal imbalances, and genetic influences that are synonymous to both obesity and poor skeletal health. Dr. Pollock has been funded by NIH to determine the influence of the hormone osteocalcin, a bone-derived protein, on energy metabolism, and he is currently funded by the American Heart Association to study the effects of vitamin K supplementation on markers of lipid and glucose metabolism in obese children with prediabetes. Additional research projects by Dr. Pollock are the following: (1) vitamin K supplement trials in three different populations (healthy children, overweight adults, and chronic kidney disease patients) to determine the roles of the vitamin K-dependent proteins, matrix Gla protein and osteocalcin, on lipid and glucose metabolism; (2) a prospective cohort study of children 8 -17 years to determine the influence of cardiometabolic risk factors on bone mineral accretion and bone structural development; and (3) drug trial (Irbesartan, Avapro®) to provide evidence that the stress-related hormone angiotensin II is a contributing factor linking mental stress to the development of hypertension and osteoporosis, particularly in salt-sensitive individuals.
