Rod Jackson on Heart-Healthy Living, Teaching Epidemiology, and the GATE Frame

Adrian interviews Dr. Rod Jackson on the Building Bridges Podcast (Butler University Dr. Medical Science Bridge Program), focusing on cardiovascular prevention and his teaching approach. Jackson argues coronary heart disease is driven primarily by dietary saturated fat, largely from meat and dairy, and urges reducing saturated fat first, then avoiding smoking, eating largely unprocessed foods low in salt and refined sugar, and exercising (which he ranks lower than diet). He recommends regular cardiovascular risk assessment, especially for older adults, and notes safe, cheap blood-pressure and lipid-lowering drugs can substantially reduce risk and that lifestyle changes help even after disease develops. Jackson explains his engaging teaching style centers on connecting with students through relatable stories (like his evidence-based lunch) and using pictures to teach epidemiology via the “GATE frame,” which he calls the epidemiological paradigm, plus a “cross” to incorporate evidence, values, politics/cost, and individual circumstances in decisions.

From Hypertension to Cardiovascular Risk: Rod Jackson’s Big-Data Impact in New Zealand

Adrian, a Butler University Medical Science Bridge Program faculty member, interviews Dr. Rod Jackson, an epidemiologist at the University of Auckland, on the Building Bridges podcast. Jackson describes growing up in rural New Zealand, choosing medicine, and shifting from clinical practice to public health after working with cardiovascular epidemiologist Robert Beaglehole, focusing on prevention such as smoking reduction. He explains how conflicting hypertension definitions led him in the late 1980s to advocate replacing single risk-factor thresholds with multivariable cardiovascular risk assessment, influencing New Zealand guidelines in the 1990s and later integrated cardiovascular risk guidelines. To replace Framingham-based estimates, he helped build a primary-care clinical decision support system that created a linked national cohort exceeding 500,000 people, producing New Zealand “PREDICT” risk equations published in The Lancet (2018) and diabetes-specific equations (2021), incorporating ethnicity and social deprivation to address inequities.
