- Perinatal programming especially related to nutrition and exercise as determinants of adult disease
- Vitamin D and bone metabolism
Dr. Atkinson’s research program is focused on developmental programming as influenced by environmental exposures (such as nutrition, physical activity, stress) during fetal, neonatal and early childhood life, which may program metabolic regulation thereby altering normal growth, body composition and risk of major non-communicable diseases in childhood and adult life.
Current research encompasses clinical trial and epidemiological investigations of the environmental (nutrition), genetic and biochemical factors during fetal, neonatal and early childhood life that play a role in defining the offspring phenotype and as risk determinants for non-communicable diseases. In a prospective, longitudinal birth cohort study children are followed from pregnancy to 10 years of age with the objective of elucidating the early determinants of obesity, diabetes, and risk of cardiovascular disease and osteoporosis. She leads a multi-disciplinary team of researchers in the conduct of randomized clinical intervention trials of nutrition and exercise in pregnancy (named B-HIP – Be Healthy in Pregnancy), designed to reduce excess gestational weight gain and to optimize maternal and child health outcomes including bone health. Research facilities include wet laboratory based investigations for analysis of biomarkers of nutritional status and metabolism and measures of bone and body composition using dual energy x-ray absorptiometry and bioimpedence; as well as dry lab space for conduct of physical anthropometry and other clinical measures.Collaborative research with colleagues has allowed expansion of investigations to include the impact of nutrition on the microbiome in pregnancy and infancy and neurobehavioural outcomes in the offspring.
Dr. Atkinson is active in training of graduate students and clinician scientists through her position as McMaster Centre Leader for the Canadian Child Health Clinician Scientist Program(CCHCSP) and Faculty in McMaster Medical Sciences Graduate Program. She serves in national and international leadership roles as Chair of the Institute Advisory Board of the Institute of Nutrition, Metabolism and Diabetes of the Canadian Institutes of Health Research (CIHR); Chair of the Board of Directors of the Maternal, Infant, Child and Youth Health Research Network (MICYRN); member of the Scientific Advisory Council for Osteoporosis Canada; and Executive of the Board of Trustees of the North American International Life Sciences Institute (Washington, DC). She is also an invited consultant on various Expert Advisory Committees for Health Canada and the National Institutes of Health in the USA.
