A review of the effects of UV filters on the environment and human health

Aug 9, 2022

The National Academies presented a public release webinar of a new report on Tuesday, August 9 from 1:00pm to 2:00pm EDT. The report, Review of Fate, Exposure, and Effects of Sunscreens in Aquatic Environments and Implications for Sunscreen Usage and Human Health, calls on the U.S. EPA to conduct an ecological risk assessment of UV filters to characterize possible risks to aquatic ecosystems and the species that live in them. The report contains information useful for such an assessment. It also describes the role of sunscreens in preventing skin cancer and what is known about how human health could be affected by potential changes in usage. The committee chairs shared key takeaways and responded to questions during the webinar.

UPennPRC and CHBR director and UPenn DBEI faculty, Karen Glanz, PhD, MPH, is on the committee. Dr. Glanz addressed the impact of UV filters on human health and stated the many factors involved, including correct application of sunscreen and the use of other barriers such as rash guards.

Healthy Weigh Study Results

Sep 7, 2021

What strategy works better for weight loss in overweight employees?

  • Financial incentives
  • Environment change strategies
  • A combination of the two,
  • On-your-own weight-loss efforts

 

Drs. Karen Glanz and Kevin Volpp, along with the team at the UPenn PRC, found that participants in all groups lost weight. Incidentally, the financial incentives group lost slightly more weight, but none of the strategies netted significantly greater weight losses than the others. The results from their Healthy Weigh Study are currently published in the September 2021 edition of JAMA Network Open.

 

In 2015, the University of Pennsylvania Prevention Research Center (UPenn PRC) conducted a study to test strategies to achieve weight loss and maintain weight loss in urban worksites in Philadelphia.

First, researchers collected data on participants who earned daily financial rewards, in addition to those guided on positive changes to their environment.

Second, they compared each strategy, separately and together, to see which one helped the participants achieve weight-loss.

Third, the team compared that data to those who tried to lose weight on their own.

Ultimately, the goal of the study was to manage obesity by improving nutrition and physical activity, in order to reduce the risk of cardiovascular disease and other chronic health conditions.
