Stricter state-level firearm legislation associated with fewer fatal police shootings

Newswise — Researchers examined whether stricter firearm legislation is associated with rates of fatal police shootings. They evaluated the effect of state-level firearm legislation on rates of fatal police shootings from Jan. 1, 2015, through Oct. 31, 2016, measuring state-level variation in firearm laws using legislative scorecards from the Brady Center and an online database of fatal police shootings maintained by The Guardian.

Results found state-level firearm legislation was significantly associated with lower rates of fatal police shootings. Controlling for sociodemographic factors, states in the top quartile of legislative strength had a 51 percent lower incidence rate than did states in the lowest quartile. Laws aimed at strengthening background checks, promoting safe storage and reducing gun trafficking were associated with fewer fatal police shootings.

“Legislative restrictions on firearms are associated with reductions in fatal police shootings,” the authors concluded. “Although further research is necessary to determine causality and potential mechanisms, firearm legislation is a potential policy solution for reducing fatal police shootings in the United States.”

Airport travelers more likely to walk to gate than take shuttle or train in response to cues

Researchers tested the effectiveness of a point-of-decision intervention to prompt walking, versus motorized transport, in a large metropolitan airport. They installed point-of-decision prompt signage at four locations in the airport transportation mall at Hartsfield-Jackson Atlanta International Airport at the connecting corridor between airport concourses. Six ceiling-mounted infrared sensors counted travelers entering and exiting the study location. They collected traveler counts from June 2013-May 2016 and used a model that incorporated weekly walking variation to estimate the intervention effect on walking.

Results found an 11 percent to 16.7 percent relative increase in walking where 580 to 810 more travelers per day chose to walk. Through May 2016, travelers completed 390,000 additional walking trips.

“The Walk to Fly study demonstrated a significant and sustained increase in the number of airport travelers choosing to walk,” wrote the authors. “Providing signage about options to walk inbusy locations where reasonable walking options are available may improve populationlevels of physical activity and therefore improve public health.”

Incarcerated persons suffer more outbreak-associated foodborne illnesses

Researchers present the first update on the epidemiology of U.S. foodborne correctional institution outbreaks in 20 years in a new study in the American Journal of Public Health. They analyzed data from the Centers for Disease Control and Prevention’s Foodborne Disease Outbreak Surveillance System to describe correctional institution outbreaks from 1998-2014 and compare them with other foodborne outbreaks.

Results found 200 foodborne outbreaks in correctional institutions were reported, resulting in 20,625 illnesses, 204 hospitalizations and five deaths. Median number of outbreak-associated illnesses per 100,000 population per year was 45 compared with seven for other outbreaks. These outbreaks accounted for 6 percent of outbreak-associated foodborne illnesses. Thirty-seven states reported at least one outbreak in a correctional institution. Clostridium perfringens was the most frequently reported single etiology. The most frequently reported contributing factor was food remaining at room temperature.

“Incarcerated persons suffer a disproportionate number of outbreak-associated foodborne illnesses,” concluded the authors,” the authors wrote. “Better food safety oversight and regulation in correctional food services could decrease outbreaks.”
