Cutter Lectures & Symposia


Since 1912, the Cutter Lecture on Preventive Medicine has been one of the most respected institutionalized lectures in the fields of preventive medicine and Epidemiology. The Cutter lectures are administered by the Department of Epidemiology at the Harvard T.H. Chan School of Public Health under the terms of the bequest from John Clarence Cutter, MD a graduate of the Harvard Medical School. In his will Dr. Cutter specified that the lectures should concern preventive medicine, should be delivered in Boston and should be free to the medical profession and the press.

The changing character of public health interests is reflected in the history of the Cutter lectures, but all have remained dedicated to enhancing the physical and social welfare of the world’s population.

The lecturers themselves have come from a variety of countries and fields of interest. While the majority of lecturers have been either American or British, many of the other European countries are represented, as well as the continents of Asia and Africa. Lecturers have been some of the most distinguished public health scientists, researchers and professionals, including the founders of modern Epidemiology and Nobel Prize recipients.

The Harvard Chan School hosts a diverse array of speakers, invited to share both scholarly research and personal perspectives. They do not speak for the School, and hosting them does not imply endorsement of their views, organizations, or employers.

Harvard T.H. Chan School of Public Health

2:05PM Quantifying Regression Dilution and Residual Confounding

Richard Peto, FRS
Emeritus Professor of Medical Statistics and Epidemiology
University of Oxford, UK

When regression analyses relate an outcome (y) to an explanatory factor (x), even purely random errors (or “noise”) in the measured values of the explanatory factor x systematically weaken the slope of the regression line of y on x, diluting the explanatory power of x (regression dilution).

Likewise, when multiple regression is used to correct for a confounding factor (x), purely random errors in the measured values of the confounding factor x systematically weaken the magnitude of that correction, so some confounding remains (residual confounding).

These two potentially substantial biases are both directly proportional to 1-r2, where r is the correlation coefficient between the exact values and the noisy values of x.

2:35PM The Limits of Confounding, the Boundlessness of Measurement Error

Donna Spiegelman, ScD
Susan Dwight Bliss Professor of Biostatistics
Director, Center for Methods Implementation and Prevention Science Yale University School of Public Health

It has been claimed that confounding is the major source of bias in epidemiology, and why epidemiology ‘gets it wrong’. Upon infinite replicates of the same trial – an unrealistic scenario — and in large single trials, randomization will balance measured, unmeasured, and still to be discovered confounders. Cornfield (1954) showed that confounding bias is limited by the minimum of the confounder-outcome relative risk, the confounder-exposure association, and the confounder prevalence. These bounds are tight, explaining why confounding adjustment often has little impact on results. On the other hand, measurement error is widespread, including in randomized nutrition trials where non-adherence may feature prominently. In contrast, measurement error bias is boundless. These remarks will be elaborated upon and illustrated by prominent examples.

3:05PM Diet and Disease: Remember Bradford Hill


Walter Willett, MD, DrPH
Professor of Epidemiology and Nutrition
Department of Nutrition
Harvard T.H. Chan School of Public Health

The early years of nutritional epidemiology were focused on measurement error in dietary assessment methods because a hypothesized effect of dietary fat on breast cancer risk was not observed in large cohort studies.  Detailed studies of questionnaire validity have shown that important associations with disease outcomes will not be missed if repeated measures are obtained and appropriate temporal relationships are examined.  When positive associations are seen, confounding is always a concern, but this can be addressed by careful study design and analysis although the effects of different constituents of foods will be challenging to distinguish.  As most dietary hypotheses will be difficult to evaluate with randomized trials, the best evidence will usually be a combination of long term cohort studies and randomized trials with intermediate endpoints.

Abstract: The Centers for Disease Control and Prevention is a 76 year-old agency and a national treasure that, for many, first came to the public’s eye in February 2020 as the earliest cases of Covid-19 reached American shores. I had the great privilege of leading the CDC for some of the most trying years of its history. Using examples from some of the public health challenges during my tenure – from Covid to Mpox to paralytic polio – I will unpack the details as to how and why some decisions were made. I will outline some of the major challenges in public health that lie ahead – from workforce to data and laboratory infrastructure to limited authorities that constrain the ability of the CDC to swiftly act in the face of infectious threats.  And, I will leave plenty of time for questions to shed some light on my wholly unexpected transition from serving as a physician-scientist leader in academia to heading a federal agency of 12,000 in the midst of a once-in-a-century pandemic.

This is an-person event with limited seating. Seats in the main auditorium is first come, first served. There is additional seating in the overflow room. There will also be a livestream of the event for those who cannot attend.

3:05PM  Life expectancy trends in the United States and the impact of drug-overdose and COVID-19 mortality

Elizabeth Arias, PhD
Statistical Analysis & Research Team, Mortality Statistics; Branch, National Center for Health Statistics
Centers for Disease Control and Prevention

The presentation will provide a historical view of trends in life expectancy at birth by race and Hispanic origin in the United States. The effects of changes over time in cause-specific mortality on changes in life expectancy will be discussed. The talk will give special emphasis to the impact on life expectancy of increases in drug-overdose mortality during the past two decades and increases in excess deaths due to the COVID-19 pandemic. Disparities by race and Hispanic origin in the effects of these recent changes in cause-specific mortality will be presented.

3:35PM     Trends in life expectancy in Western European countries and other indicators of longevity

Jean-Marie Robine, PhD
Emeritus Research Professor, French National Institute of Health and Medical Research (INSERM), Emeritus Professor, Ecole pratique des hautes études

Between the trends in life expectancy observed in Japan and the United States of America, what can we learn from the trends observed in Western Europe when the main assumptions about the limits of human longevity are based on European data? This paper compares and discusses recent trends in life expectancy in the main Western European countries. Possible causes of the observed trends, heat waves, flu epidemics, Covid-19 will be discussed.

4:05PM  Public Health Strategies for Addressing the Opioid Crisis

Howard Koh, MD
Harvey V. Fineberg Professor of the Practice of Public Health Leadership
Department of Health Policy and Management
Harvard T.H. Chan School of Public Health

This session will describe the rising toll of US drug overdose deaths with a focus on the growing contribution of the opioid epidemic. it will focus on dynamic aspects of the epidemiology that have contributed to striking declines in US life expectancy through the pandemic. The 2022 Stanford- Lancet Commission on the North American Opioid Crisis offers a comprehensive analysis of root causes of these trends and public health strategies to address them. The speaker will review the interdisciplinary recommendations from that Commission and emphasize the need for a public health approach to address stigma and advance treatment, harm reduction, recovery and prevention.
