The study, published last week by VA researchers in the Journal of Occupational and Environmental Medicine, found a higher rate of hypertension among members of the Army Chemical Corps who handled Agent Orange during the war compared to those who didn’t. Corps members who served in Vietnam but did not spray the chemicals also had a higher rate of hypertension than their peers who served outside Vietnam.
Both results were statistically significant and add to a body of evidence linking Agent Orange exposure and hypertension.
The findings come 41 years after the close of the Vietnam War and decades since the last supplies of Agent Orange were incinerated. Since then, veterans have become increasingly distrustful of the VA. They maintain that their exposure to Agent Orange, which contained the toxic chemical dioxin, has harmed their health and has been passed on to their children.
A VA working group has been studying the latest scientific literature since March to determine whether any illnesses should be added to the agency’s list of diseases for which vets are automatically entitled to compensation if they served in Vietnam. Specifically, the group has been looking at new evidence linking bladder cancer, underactive thyroid, Parkinson’s-like symptoms and hypertension to Agent Orange exposure.
The VA had been expected to announce its decision this year, but officials now say that will be left to the administration of President-elect Donald Trump.
“For this administration, the deadline for proposing new rules for potential new presumptions [of service connection to herbicide] has passed, and this will become work for the new administration to take to completion,” VA officials said in a written statement first reported last week in Stars and Stripes.
Hypertension is the most common ailment among veterans seeking health care at the VA. It is one of the most common ailments among older adults generally.
The study released last week found the prevalence of hypertension among members of the Army Chemical Corps to be higher than among other aging veterans. Although most of the Agent Orange used in Vietnam was sprayed from Air Force planes, the Army Chemical Corps also sprayed the herbicide from hand sprayers and helicopters.
