Get Ready to Argue About the SELECT Outcomes Study

July 8, 2023 — It’s coming. Sometime before September we will be hearing about the results of the SELECT outcomes study of semaglutide in people with obesity and we may as well start getting ready to argue about it now. Because value is in the eye of the beholder. And this study is all about the long-term health value […]

Preventing Long COVID for People with Obesity

June 12, 2023 — In many ways, COVID seems to be in the rear view mirror. Travel, meetings, and busyness have cranked up to a level that makes it seem like the pause we took for the pandemic is a distant memory. But not for folks who develop long COVID – which is about ten percent of people who […]

A Cluster of Unreliable Prevention Studies

March 18, 2023 — The search for effective prevention strategies in obesity is daunting. For decades now, researchers have been casting about for effective ways to educate, nudge, or cajole groups of people into moving more and eating less or better. Trying to influence a group of people means that controlled studies of interventions can wind up being cluster-randomized […]

Stepping Up Your Steps: Is More Really Better?

October 12, 2022 — In a typical day, most people really don’t move around that much. The simplest way of quantifying this is by counting steps and the average for an American adult is between three and four thousand per day. The default goal for improving on this became 10,000 steps – probably because an early pedometer called the […]

Distinguishing Medical and Social Problems

September 22, 2022 — Problems are messy, so to solve them, humans quite naturally move to make them tidy. We sort them, label them, and get to work on resolving them. But news this week reminds us that health issues often resist our efforts to sort them out and find tidy solutions. The USPSTF this week published a draft […]

Nope, Vitamin D Does Not Prevent COVID

September 8, 2022 — It really is becoming hard to remember just how we were clutching at straws to cope with the pandemic two years ago when all we had to prevent COVID was social distance and masks. No vaccines or Paxlovid. One of the straws we were clutching then was vitamin D. Both our ex-President and Tony Fauci […]

Obesity, COVID, Mortality, and Trust

February 4, 2022 — By all traditional measures of public health, Vietnam was in a bad spot when the COVID pandemic began in 2020. It is a small country with weak health and political systems. But early in the pandemic, it succeeded in keeping infections and deaths low. By contrast, the U.S. has done rather poorly. Despite a high […]

Vitamin D and COVID: More Noise Than News

November 15, 2021 — Last year, when we didn’t have many great options for dealing with COVID-19, interest in vitamin D was keen. A number of studies found a correlation between vitamin D levels and COVID risk. So splashy headlines ensued. Even the former president and Tony Fauci told us they were taking it. But in retrospect, those headlines […]

For Teens with Obesity, COVID Vaccines Save Lives

October 21, 2021 — A new report in MMWR this week provides a stark reminder. COVID vaccines save lives – especially for teens with obesity and other medical conditions. The study analyzed 464 patients 12 to 18 years old. Of those, 179 were hospitalized with COVID-19 and 285 were case controls. Nearly three quarters (72 percent) of these patients […]

Vitamin D Helps with Respiratory Infections – But COVID?

March 31, 2021 — Public enthusiasm for vitamin D during the COVID pandemic has been impressive. An ardent fan base follows every twist and turn in this saga. Observational studies find lower risk in people who have higher vitamin D level. Then an RCT comes along to muddy the water by finding no benefit. Two new studies provide new […]
