Massachusetts child obesity rates improve, except among the poor
Massachusetts childhood obesity and overweight rates showed an overall improvement between 2009 and 2014, but disparities among children of different socioeconomic and geographic backgrounds widened, according to new research from the American Journal of Public Health.

Researchers reviewed data from 275 Massachusetts public school districts that annually captured body mass index of students in first, fourth, seventh and 10th grades between the school years 2008-2009 and 2013-2014. The BMI data was reviewed alongside corresponding school district, gender, district-level median household income and report year. Researchers sought to understand trends or changes in obesity and overweight prevalence over the six years after Massachusetts’s 2009 mandated annual screening of BMI.

Results from the study indicate that despite a high prevalence of childhood overweight and obesity, there was an overall decline between 2009 and 2014. However, prevalence only improved among districts with a median household income greater than $37,000. Obesity and overweight rates remained unchanged over the course of the study for the poorest children. Additionally, declines were only seen among children in first and fourth grades, suggesting an opportunity for intervention during these grade levels.

“Although overall prevalence began to decrease, the geographic and socioeconomic disparities in childhood obesity are widening and remain a public health challenge in Massachusetts. Special efforts should be made to address the needs of socioeconomically disadvantaged districts and to narrow the disparities in childhood obesity,” the authors suggest.

States with more gun owners experience more law enforcement homicides
New research from the American Journal of Public Health finds that there is a greater likelihood of law enforcement homicide among states with greater public gun ownership rates.

Using data from the Uniformed Crime Reporting database, the study reviewed annual homicide counts of law enforcement officers for every state and the District of Columbia between 1996 and 2010. The study compared the statewide law enforcement officer homicide rate against each state’s public firearm ownership rate using data from the Behavioral Risk Factor Surveillance System. Researchers controlled for state violent crime rates in their analysis.

Results from the study indicated that states with high prevalence of public firearm ownership pose a greater risk for law enforcement officer homicide than states with lower public firearm ownership rates. According to the study, 10 additional law enforcement officer homicides could result from a 10 percent increase in firearm ownership rate, over the course of 15 years.

“Law enforcement officers working in states with higher levels of gun ownership faced a greater likelihood of being shot and killed on the job compared with their peers in states with lower gun ownership. The differences were large. Officers in the high-gun states had three times the likelihood of being killed compared with low-gun states,” the authors explain.

Bicycle couriers make up a large proportion of NYC injured cyclists  
New research from the American Journal of Public Health finds that commercial bicyclists, defined as business employees operating bicycles for delivery purposes, are frequently injured by motor vehicles. They make up one quarter to one half of all injured cyclists annually treated at Bellevue Hospital Center, a level 1 trauma center.  

Researchers reviewed data from Bellevue Hospital which captured information about more than 800 New York City bicyclists who were injured by motor vehicles and treated at the trauma center. Among the sample, the study collected a number of variables including demographic information, commercial status, helmet use, alcohol use and riding behaviors.

Results from the study indicate that commercial bicyclists make up 24.4 percent to 45.1 percent of injured bicyclists treated in the trauma center annually. These bicyclists tend to be young men and most frequently are of Latino origin. Commercial bicyclists are less likely to have consumed alcohol or to have been distracted by the use of an electronic device. Commercial bicyclists did not differ from other riders in helmet use but had less severe injuries.

“Commercial bicyclists represent a unique cohort of vulnerable roadway users who have received little attention in the scientific and epidemiological literature,” the researchers conclude.
