Epidemiology Counts – Episode 8 “Gun Violence”

Gun violence is endemic in the United States. It’s become a politically polarized topic and the discourse, which tends to focus on mass shootings, is replete with misinformation. Key questions underlying this debate are inherently epidemiological and population research can help separate fact from fiction. For example, what does the data tell us about trends in gun ownership and gun violence in the United States? To what extent are gun deaths attributable to mass shootings and murders versus gun suicides? What policy levers regulate gun ownership and use, and what do we know (and not know) about their impacts? In this episode, guest Dr. David Hemenway, Director of the Harvard Injury Control Research Center, joins Matt Fox and Arijit Nandi in grappling with these fundamental questions, and tries to bridge the gap between the perceived and actual reality of gun violence in the United States.  

Epidemiology Counts – Episode 7 “Vaping”

While cigarette smoking has declined in the US, vaping has increased dramatically—especially among younger Americans. While vaping may be less harmful to human health than combustible tobacco products like cigarettes, it still contains highly addictive nicotine and other potentially harmful but not well-understood chemicals. And yet many of us don’t really know exactly what vaping is and how it differs from cigarette smoking. Should vaping be seen as a less harmful alternative to cigarettes for smokers, or a gateway to nicotine and other addictions for teens and current non-smokers? How is vaping regulated and does this need to change? ​In the sixth episode of Epidemiology Counts, Bryan James and Matt Fox interview Dr. Craig Ross from the Boston University School of Public Health about the health effects and increasing rates of vaping, and whether this can be seen as a net benefit or harm to society.

Epidemiology Counts – Episode 6 “Influenza”

Did you get your flu shot? Employers and other institutions that have a stake in our health, wellbeing and productivity have decided the flu shot is a worthwhile investment. However, many people seem ambivalent about the flu shot. What is behind these different perspectives? In the 6th episode, Matt Fox and Jennifer Ahern interview Dr. Arthur Reingold on the topic of influenza and the flu vaccine. In this episode we uncover some of the details behind the flu as a disease, its transmission, and learn about the flu vaccine to help everyone make better informed decisions for themselves and their families.

Epidemiology Counts – Episode 5 “Consequential Epidemiology”

How do we know what’s really making us sick? And how to do we make it better?  If we read the newspaper, we might think it’s whether we follow a low fat diet, whether we took the stairs those two flights to our office instead of jumping on the elevator, and ditching cigarettes once and for all. But our guests today, Sandro Galea and Katherine Keyes, will argue that those decisions are all part of a broader picture of what drives health, and that intervening upstream of diet and cigarettes has a greater potential to affect the health of populations. We know that education, poverty, social injustice, and health care system organization have vast consequences for life and health; Galea and Keyes will discuss how these factors shape population health, and what we can do to re-prioritize research so that we maximize the potential to improve health for many.

Epidemiology Counts – Episode 4 “Sweeteners”

Did you know there are 39 grams of sugar in a standard can of soda? That’s approximately equal to consuming 10 sugar cubes in one sitting! In the fourth episode, Matt Fox and Hailey Banack interview Dr. Barry Popkin on the topic of sugar sweetened beverages. In this episode we highlight the links between sugar sweetened beverages and obesity and discuss some ideas for public health policy to limit consumption of sugar sweetened beverages.

Epidemiology Counts – Episode 3 “Plastics and Public Health”

In the third episode, Matt Fox and Anna Pollack interview Leonardo Trasande, MD, MPP, professor at NYU Langone Health, on plastics. In this episode, we answer that nagging question as you microwave your lunch – should we microwave our food in plastic? Do plastics in consumer products reflect a health risk? If so, how could we change our habits to minimize that risk?

Epidemiology Counts – Episode 2 “Community Immunity”

In the second episode, Matt Fox, Justin Lessler and Jennifer Ahern discuss the concept of herd immunity or community immunity. What is it? What has it accomplished? How do we know it works? What happens when we lose it? Interviews with Walter Orenstein, Elizabeth Halloran and Saad Omer, enrich the discussion by bringing historical, technical and social perspectives to understanding of this important phenomenon.

Epidemiology Counts – Episode 1
“Why should I trust that new health study?”


Welcome to Epidemiology Counts from the Society for Epidemiologic Research! Each episode delves into a particular disease or health condition or something that we are exposed to in our daily lives that may affect our health, and bring you a look at what we currently know and don’t know about each of these conditions or potential causes of disease.

In this inaugural episode, Matt Fox, Hailey Banack, and Bryan James give a big picture look at why you should believe anything epidemiologists do and how you can digest all the health information you hear in a way that makes sense and will set the stage for future episodes that take on specific disease areas.
