American Journal of Public Health June issue research highlights:
Lack of transportation impedes access to health care
Nearly 6 million U.S. adults delay medical care each year because they lack transportation to health care facilities, a study in the June issue of APHA’s American Journal of Public Health finds.
Researchers examined data from the National Health Interview Survey between 1997 and 2017, analyzing responses from people who said they had delayed care in the past year.
In 2017, about 5.8 million adults reported delaying doctor’s visits because they lacked transportation, the researchers found. Overall, about 2% of women said they delayed care because of transportation barriers in 2017, as did 1.5% of men.
Education played a role, with the least educated having the hardest time getting to health care facilities. Income was also a factor: About 7% of people who delayed care because of transportation barriers had yearly earnings below the U.S. poverty line.
Nearly 12% of people who delayed care said they had poor health, suggesting chronic ailments may have played a role in lack of access to transportation. Of those respondents, 7% had kidney problems and nearly 7% were stroke survivors.
“Transportation barriers to health care have a disproportionate impact on individuals who are poor and who have chronic conditions,” the researchers said.

Bike sharing reduces crashes between cars, cyclists
City bike-share programs result in more people bicycling, while also lowering the risk of crashes between cars and cyclists, a study in the June issue of AJPH finds.
Researchers reviewed data from Philadelphia, examining crashes between cars and cyclists that were listed in the Pennsylvania Department of Transportation Public Crash Database between 2010 and 2018.
Researchers looked at over 4,450 crashes that resulted in vehicle damage and at least one injury. Before the introduction of Indego — Philadelphia’s city-run bike-sharing program — in 2015, such crashes decreased on average about 1%.
But from 2015-2018, after Indego was in use, crashes involving cars and bikes decreased by 13%. The drop occurred even though more bicyclists were riding in the city and no citywide bike infrastructure had been built to help protect the riders.
The “safety-in-numbers theory” may explain the decrease, according to study researchers. With more bicyclists throughout Philadelphia, drivers changed their behavior, watching out for bicyclists, resulting in proportionally fewer crashes, they said.
“Our results suggest that, in the long run, bicycle-share programs do not lead to increases in the rates of bicyclist injuries caused by crashes with motor vehicles and, in fact, may accelerate their decrease,” the researchers suggested.

Firearms contribute to increases in brain injury-related deaths
Deaths from traumatic brain injuries have increased in the U.S. in recent years, with firearm-related suicides accounting for almost half of the surge, a study in the June issue of AJPH finds.
Researchers examined records in the National Vital Statistics System from 2008 to 2017, focusing on information on deaths from head injuries. Over 500,000 cases were identified, involving both adolescents and adults. Intent and means of death were classified using data from the National Center for Health Statistics.
The researchers found that firearm suicide accounted for about 48% of the increase in TBI-related deaths over the study period. Unintentional falls accounted for about 44% of the increase, followed by gun-related homicides, at about 4%, nonfirearm-related suicides, at about 1%, and other causes making up the remainder.
Most of the TBI-related firearm suicides involved men. In 2017, almost 18,000 men died by that means, compared to about 2,700 women. Over 60% of the deaths occurred at home.
Public health and safety workers should prioritize suicide prevention, especially through policies restricting or limiting access to a firearm, the researchers said.
“Safe storage of firearms among people at risk, and training of health care providers and community members to identify and support people who may be thinking of suicide, are part of a comprehensive public health approach to suicide prevention,” they said.

Labels on juice drinks for kids blur nutritional value
Labels on juice drinks are not helpful in determining which products are healthy for children, a study in June’s AJPH finds.
Researchers examined federal laws governing juice labels, then analyzed information from 39 children’s juice drinks. While the U.S. Food and Drug Administration specifies offers terms that may be used to describe a product on its label — such as 100% juice, flavored water, juice drink or natural flavor — deceptive labeling makes it difficult to distinguish healthy products from those with added sugar and sweeteners with no nutritional value, the researchers found.
“We identified numerous labeling practices that obscure the true nature of drinks purporting to contain juice and would make it difficult for consumers to identify healthier products,” the researchers said. “Labeling practices appear to be designed to blur the distinction between drinks recommended for children and those containing added sugar or nonnutritive sweeteners.”
While health and nutrition experts recommend that children do not consume products with added sugar and sweeteners, the confusing labeling practices make it hard for consumers to select healthy products, the study found.
“The FDA should revise its regulations to ensure the labels for drinks containing or purporting to contain juice are clear and not misleading,” the researchers said.
