A survey of parents across the United States estimates that one in 40 children has autism spectrum disorder, according to a study published Monday in the journal Pediatrics.In other words, the condition was reported in 2.5% of children, representing an estimated 1.5 million kids ages 3 to 17.A report released this year by the US Centers for Disease Control and Prevention estimated the prevalence at one in 59 children or about 1.7%, based on 2014 data."Prevalence is not growing that rapidly, although the CDC's data suggests it is still growing," Thomas Frazier, chief science officer of the advocacy organization Autism Speaks, said in an emailed statement. He was not involved in the new report."What is happening is that these studies use methods that are a bit more liberal and inclusive than the CDC's methods," Frazier said, adding that he prefers the CDC's numbers but understands "that they are likely a bit conservative."The new study is based on the 2016 National Survey of Children's Health, which was conducted by the US Census Bureau and which collected information from parents of more than 50,000 children up to age 17. To be included in the estimate, parents would have had to report that their child had ever received a diagnosis of autism spectrum disorder and that they currently had the condition.The new numbers were also slightly lower than those in the 2017 National Health Interview Survey. It estimated that 2.76% of children had ever received such a diagnosis, which the authors of the new report note is a broader definition.The fact that the new study relies on parental reporting -- which is not validated by health and education records, as in the CDC report -- may be a limitation despite the broad scope of the research, the authors say.Frazier said the 1-in-40 figure is "generally consistent with previous parent surveys and other direct prevalence studies where researchers directly screen for and attempt to identify autism."The parents in the new study also reported more difficulties getting the health care their children need, versus those with Down syndrome, or other behavioral disorder, such as attention-deficit hyperactivity disorder."Though we've seen progress in recent years, this confirms what we know from our parents -- that many children face unacceptable delays in getting a diagnostic evaluation, even after parents, teachers or other caregivers have recognized the signs of autism," Frazier said.In the new study, more than a quarter of children with autism spectrum disorder were taking medication for symptoms related to the condition, and nearly two-thirds have received "behavioral treatments" in the past year, the study says.It also found a higher prevalence for autism spectrum disorder among certain groups such as boys, children of single mothers and households below the federal poverty level, compared with those at least four times above that income threshold.The differences between the new study's numbers and those of the CDC study might be explained by the years they were conducted, the ages of children studied and where they lived, according to the new study.The CDC report was based on data collected from 11 communities across the country but was not necessarily nationally representative, according to that report's co-author Daisy Christensen, surveillance team lead in the developmental disabilities branch of the CDC's National Center on Birth Defects and Developmental Disabilities."Parents know their child best," Christensen, who was not involved in the new report, previously told CNN. "We want to encourage parents to be aware of their child's development, to be aware of the milestones that children achieve."Autism spectrum disorder, a lifelong developmental disability, is characterized by problems with communication and social interaction with accompanying repetitive behavior patterns.The authors note that it's difficult to compare the new report with prior iterations due to updates in how the survey collected its data and how questions were worded."We cannot tell what proportion was explained by internal survey changes rather than external factors," the authors wrote.Still, the report comes as estimated prevalences of the disorder have been rising for decades."Over the '80s and '90s, the diagnostic criteria expanded to include more children," Christensen said, "so I think that's definitely a possibility for the increase that we've seen."In the past, more than half of children identified with autism also had intellectual disability, and now it's about a third, she said. "And that's really consistent with identifying children who are perhaps at the milder end of the spectrum."The new study's authors also note that universal screening recommendations in the 2000s may have led to a rise in prevalence among younger children, for example."Because there is no biological marker, [autism spectrum disorder] is a particularly challenging condition to track," the authors note.But understanding how common it is allows health experts to distribute resources and get families the help they need, according to Frazier."Having prevalence estimates -- even if there is some variation -- helps us to advocate for improved screening, diagnosis, interventions and supports," he said. 5314

A new boarding process is coming to Delta Air Lines.Beginning on January 23, 2019, the airline will ditch zone boarding in favor of a new — and more complex — process based on ticket type and color.Despite the expansion in number of groups from six to eight, Delta said the new format hopes to "encourage fewer customers to line up in the gate area" and ultimately speed up boarding.The Atlanta-based carrier will still begin boarding with passengers that need extra time, followed by premium passengers sitting in its Delta One suites (applicable on select domestic and all international flights) and then its new Premium Select cabin on some international flights or First Class on domestic flights.After that, it gets complicated: The airline used to board the Sky Priority zone — passengers sitting in Comfort+ and Gold and Platinum Medallion members — together.Moving forward, that group will split into two, with Comfort+ passengers boarding first followed by Sky Priority, meaning high-spending members of its frequent flier program will have to wait a little bit longer.Following that, Delta will board economy passengers by announcing Main Cabin 1 though 3, instead of Zone 1 though 4.Fliers that purchase Delta's cheapest tickets will board last in a new group: Zone 4 will now be called Basic Economy. Delta credit card holders and Silver Medallion members will board with Main Cabin 1.Each section will have different colors displayed when they purchase their ticket on Delta's website and on airport screens to help."This latest enhancement further refines how Delta's process works and is designed to better link the Delta product they purchased to differentiated experiences throughout their journey," said Tim Mapes, Delta's chief marketing officer, in a statement.Delta (DAL) joins United (UAL) and American (AAL), which both recently revamped their boarding processes. The goal is to minimize delays and load planes quicker. 1950

A St. Louis couple who waved guns at peaceful protesters near their property earlier this year will speak in support of President Donald Trump next week at the Republican National Convention, The Washington Post, NPR and CNN report.The couple will reportedly deliver remarks remotely, as in-person portions of the convention have been canceled.Mark and Patricia McCloskey gained national attention in late June as Black Lives Matter protesters marched toward the home of St. Louis Mayor Lyda Krewson. Krewson and the McCloskeys live in a private, gated community.Though the protesters were peaceful and staying away from the McCloskey's mansion, the couple emerged from their homes with firearms and ordered protesters to leave.Various social media videos show Patricia McCloskey pointing a small handgun at protesters. Mark McCloskey carried a long gun.In July, the couple was charged with unlawful use of a weapon for waving the guns in a "threatening" manner. Both have maintained their innocence, saying they were afraid for their lives and were simply protecting themselves.The White House has previously expressed support for the couple. Press Secretary Kayleigh McEnany said in July that the charges against the McCloskeys were "absurd." Missouri Gov. Mike Parson has also said he's spoken with Trump about the situation.The RNC will take place next week between Aug. 24 and Aug. 27. 1398

A student at Island Park High School in Florida was suspended after the principal and other staff members saw him imitating a gun with his hands and pretending to shoot in a classroom.This happened Friday. "You shouldn't be doing something like that at all," former Island Park High School student Devan Hinton said."It's just not something to be taken lightly," Sam Sherman, who lives in Fort Myers, told Scripps station WFTX in Fort Myers, Florida.The principal called the Lee County Sheriff's Office to file an incident report after he saw the student "imitating a rifle with his hands and pointing it to the classroom."Another staff member described the student making "a gesture with his arm simulating as if he was firing a weapon into the classroom."A third staff member said the student "stood in the classroom doorway and made a machine gun style pose with his arms pretending to shoot at the classroom.""That isn't OK. With everything going on, that's not something to joke about. That's lives in someone's hands," Hinton said.The principal said he didn't think the student was serious but will not tolerate this behavior in school, so he suspended him.It's an action Sherman said he agrees with for the safety of the students."It's better to be preventative than wait and let it go on, and God forbid something else occur," he said.The principal of Island Park High School, Arthur Nauss, sent WFTX this statement:"I took the disciplinary action of sending the student home after I observed him pointing his finger at another student imitating that he was shooting a gun. The student pointing the finger and the student he was pointing at know each one another and were laughing at one another. There was no threat being issued but I believe it necessary to make it clear to the student, and all our students, that this is unacceptable behavior considering the recent events here in Florida. I called the student’s mother to inform her of what had occurred and let her know I would be working with the student in the future to ensure this behavior does not reoccur.When the student returns to school he will be informed that any future actions such as this one will result in a suspension or expulsion from school. I will also let him know that actions like this in the future will be reported to the appropriate authorities." 2379

A new study by the Institute for Health Metrics and Evaluation found in the past 10 years, the number of deaths attributed to alcohol has gone up 35 percent. Among women, alcohol-related deaths soared 85 percent.Ron and June Byrd know the pain of watching a loved one struggle with alcohol. They helplessly watched their daughter, Erika, fight it for years.“It would have to be in all caps: helpless. As a father, I was supposed to be able to fix things. I couldn't fix it,” Ron Byrd says.After becoming partner at her law firm, doctors diagnosed Erika with breast cancer. Her parents say she became depressed, and it made her drinking worse.Rehab didn’t work.“Despite our best effort, her friends’ best efforts, her best efforts, it was to no avail,” says Ron. “And it killed her.”Erika died in 2011 at the age of 42.Her death is part of a disturbing, growing trend.“I just know it's a terrible epidemic,” Ron says. “Alcohol kills you in many ways: suicides, accidents, organ failures, disease.”The study by the Institute for Health Metrics and Evaluation found this spike started during the recession and that growing pressure on working mothers might also play a role.“They are, I think, by in large, ashamed of it. Our daughter was,” Ron says. “They do their best to hide it until they can't.”Erika's parents hope the report helps break the stigma associated with alcoholism and leads to more resources devoted to fighting the problem. 1447
