In March, for example, HHS dropped questions about sexual orientation and gender identity in two surveys of elderly people.
HHS has also removed information about LGBT Americans from its website. The department's Administration for Children and Families, for example, archived a page that outlined federal services that are available for LGBT people and their families, including how they can adopt and receive help if they are the victims of sex trafficking.
At the CDC, the meeting about the banned words was led by Alison Kelly, a senior leader in CDC's Office of Financial Services, according to the CDC analyst who spoke on the condition of anonymity because the person was not authorized to speak publicly.
Kelly did not say why the words are being banned, according to the analyst, and told the group that she was merely relaying the information.
Other CDC officials confirmed the existence of a list of forbidden words. It's likely that other parts of HHS are operating under the same guidelines regarding the use of these words, the analyst said.
At the CDC, several offices have responsibilities for work that uses some of these words. The National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention is working on ways to prevent HIV among transgender people and reduce health disparities. The CDC's work on birth defects caused by the Zika virus, for example, includes research on the developing fetus.
The ban is related to the budget and supporting materials that are to be given to CDC's partners and to Congress, the analyst said. The president's budget for 2019 is expected to be released in early February. The budget blueprint is generally shaped to reflect an administration's priorities.
The words to avoid:
• Vulnerable
• Entitlement
• Diversity
• Transgender
• Fetus
• Evidence-based
• Science-based.
Federal agencies are sending in their budget proposals to the Office of Management and Budget, which has authority about what is included.
Neither an OMB spokesman nor a CDC spokeswoman responded to requests for comment Friday.
The longtime CDC analyst, whose job includes writing descriptions of the CDC's work for the administration's annual spending blueprint, could not recall a previous time when words were banned from budget documents because they were considered controversial.
The reaction of people in the meeting was "incredulous," the analyst said. "It was very much, 'Are you serious? Are you kidding?' "
"In my experience, we've never had any pushback from an ideological standpoint," the analyst said.
News of the ban on certain words hasn't yet spread to the broader group of scientists at the CDC, but it's likely to provoke a backlash, the analyst said. "Our subject matter experts will not lay down quietly - this hasn't trickled down to them yet."
The CDC has a budget of about $7 billion and more than 12,000 employees working across the nation and around the globe on everything from food and water safety to heart disease and cancer to infectious disease outbreak prevention. Much of the CDC's work has strong bipartisan support.
Kelly told the analysts that "certain words" in the CDC's budget drafts were being sent back to the agency for corrections. Three words that had been flagged in these drafts were "vulnerable," "entitlement" and "diversity." Kelly told the group she had been authorized to give verbal instructions about the remaining banned words.
