A new government report reveals that a surprising number of boys received the vaccine for human papillomavirus (HPV) last year, the first year that it was recommended for adolescent boys. The Centers for Disease Control and Prevention says 1 in 5 boys received at least one dose of the HPV vaccine, NBC News reports.
Shared through sexual contact, HPV can cause cervical cancer in women and genital warts in both sexes, and in rare cases, throat and anal cancer. The vaccine was first recommended for girls ages 11 and 12 beginning in 2006, and then recommended for boys in 2011. More from NBC News:
The shots are largely intended not to protect boys from disease, but to stop them from spreading a sexually transmitted virus to girls that could cause cervical cancer.
The vaccine hasn’t been very popular among girls. The government report issued Thursday is the first real sense of how many boys are getting the shots.
“It’s a good start,” said Shannon Stokley, a vaccination expert with the Centers for Disease Control and Prevention.
Introduced in 2006, the vaccine protects against human papillomavirus, which is spread during sex. Most infections go away on their own, without people developing symptoms. But the virus can cause cervical cancer in females, genital warts in both sexes, and some other, less common conditions like throat and anal cancer.
The vaccine was first recommended for girls ages 11 and 12 because it works best if given before a teen starts to have sex. In 2011, it was also recommended for boys that age to help prevent the virus’s spread.
The CDC report covers vaccination rates for last year, the first full year since the shots were advised for boys. It’s based on telephone calls to families for about 19,000 boys and girls ages 13 to 17.
About 21 percent of the boys had gotten at least one of the three doses. Less than 7 percent were fully vaccinated.
The rates look relatively good compared to the initial rates for some other vaccines aimed at adolescents. For example, the initial rate for a meningococcal vaccine was just 12 percent.
Rates tend to start low when a vaccine is first recommended and build after. So the HPV numbers for boys are reason to be optimistic, said the CDC’s Dr. Melinda Wharton, although she added a word of caution.
“Given how the coverage level has stalled for girls, though, a solid start isn’t enough,” she said.

A survey by the Centers for Disease Control and Prevention finds that schools are making some strides in helping kids make healthy choices. The report revealed a jump in the number of schools phasing out junk foods, and found more elementary schools offering gym classes. More from The Washington Post:
[A]fter years of efforts to phase out junk food like candy and chips, the percentage of school districts that prohibited such food in vending machines increased from 29.8 percent in 2006 to 43.4 percent in 2012, according to the CDC’s 2012 School Health Policies and Practices Study. Also, slightly more than half of school districts – up from about 35 percent in 2000 — made information available to families on the nutrition and caloric content of foods available to students.
“Schools play a critical role in the health and well-being of our youth,” said CDC Director Tom Frieden, in the news release. “Good news for students and parents — more students have access to healthy food, better physical fitness activities through initiatives such as ‘Let’s Move,’ and campuses that are completely tobacco free.”
Since 2000, the number of school districts that require elementary schools to teach physical education increased. In addition, the number of districts entering into agreements with local YMCAs, Boys & Girls Clubs or local parks and recreation departments went up, according to the study.
Meanwhile, the percentage of districts with policies that prohibited all tobacco use during any school-related activity increased from 46.7 percent in 2000 to 67.5 percent in 2012.
The CDC study is a periodic, national survey that examines key components of school health at the state, district, school, and classroom level, including health education; physical education and activity; health services; mental health and social services; nutrition services; healthy and safe school environment; faculty and staff health promotion; and family and community involvement.

With many women waiting to get married and have children, the number of couples who pursue medical treatments to become pregnant seems to be growing exponentially. But new data from federal researchers at the National Center for Health Statistics shows that the national infertility rate has remained virtually unchanged for the past 20 years. More from NBC News:
“Infertility rates have come down a little bit,” says Dr. Anjani Chandra, researcher at the NCHS, part of the Centers for Disease Control and Prevention. “That surprises people because they think it is going up. In fact, it really hasn’t been the case.”
Chandra and colleagues looked at data from the National Survey on Family Growth, in which more than 22,000 people were interviewed face to face between 2006 and 2010. The survey was also done in 1982 and 2002.
The surveys showed that 8.5 percent of married women aged 15 to 44 were infertile in 1982 – defined as having been married and having unprotected sex for 12 months without becoming pregnant. This fell to 6 percent of the same age group, married or unmarried, in 2006-2010.
When they added in women who could finally get pregnant but who miscarried before giving birth, the number rose to 11 percent
“Contrary to popular perceptions based on infertility service use and media coverage about biological clocks, we still don’t see that,” Chandra told NBC News.
It hasn’t changed for men, either.
“Some form of infertility … was reported by 9.4 percent of men aged 15–44 and 12 percent of men aged 25–44 in 2006–2010, similar to levels seen in 2002,” Chandra’s team writes in the report.
One obvious answer would seem to be increased use of fertility treatments. Since 1982, in vitro fertilization or IVF has been perfected, and more than 163,000 treatments were done in 2011 – just about double the number done a decade before. Federal law requires doctors and clinics to report fertility treatments and success rates to the CDC.
But this data doesn’t show whether 163,000 separate people were treated, and the new statistics suggest that in fact more people aren’t being treated. Instead, individuals may be undergoing more treatments in the same year, says Chandra.
That’s because the percentage of women who have ever gotten fertility services was the same in 2006-2010 as compared to 2002 – 11.9 percent in both times.
Dr. Richard Reindollar of the American Society for Reproductive Medicine said the findings were encouraging.
“Even though the ages at which women in the United States have their children have been increasing since 1995, the percentage of the population suffering from infertility or impaired fecundity has not increased,” Reindollar said in a statement.

A decline–small, but significant, experts say–in the obesity rate among preschoolers growing up in low-income family is offering a glimmer of hope that efforts to combat the childhood obesity epidemic may be working. The Centers for Disease Control and Prevention released news of the decline in a recent report. USA Today has more:
Florida, Georgia, Missouri, New Jersey, South Dakota and the U.S. Virgin Islands had the largest absolute decreases in prevalence of obesity, with a drop of at least 1 percentage point, the report says. Obesity rates held steady in 20 states and Puerto Rico. They rose in Colorado, Pennsylvania and Tennessee.
Researchers analyzed weight and height data of about 11.6 million children ages 2 to 4 in federally funded maternal- and child-nutrition programs. The data came from the Pediatric Nutrition Surveillance System.
“Although obesity remains epidemic, the tide has begun to turn for some kids in some states,” Frieden says. “While the changes are small, for the first time in a generation they are going in the right direction.”
Previous research has shown that about one in eight preschoolers are obese in the USA, the CDC says. Preschoolers who are overweight or obese are five times more likely than their normal-weight peers to be overweight or obese as adults.
“It’s great news, but it’s too early to say that I feel confident that we are securely on the path to improvement,” said James Marks, senior vice president at the Robert Wood Johnson Foundation, a philanthropy devoted to public health.
The results are surprising, he said, “because of the speed at which the epidemic appears to be turning around.” The report shows “the highest-risk children in almost half of the states are getting healthier.” Marks, a pediatrician, is the director of the health group of the Princeton, N.J.-based foundation.

Half of American new mothers now breastfeed their newborns for the recommended period of at least six months, according to data analyzed by the Centers for Disease Control and Prevention. More from Today.com:

It’s a big increase from just 35 percent in 2000 and is good news for babies and moms alike, as breastfeeding boosts the immune system, may lower the risk of obesity and is even linked with higher intelligence.
“This is great news for the health of our nation because babies who are breastfed have lower risks of ear and gastrointestinal infections, diabetes and obesity, and mothers who breastfeed have lower risks of breast and ovarian cancers,” said Centers for Disease Control and Prevention director Dr. Tom Frieden.
The American Academy of Pediatrics recommends that newborns get nothing but breastmilk until they are six months old. The AAP recommends that mothers continue to breastfeed, along with giving other food, after six months for at least a year or even longer “as mutually desired by mother and infant.”
Studies show that babies given nothing but breastmilk for the first four months of life have a 72 percent lower risk of severe pneumonia and other lower respiratory tract infections for their first year. If moms stop breastfeeding between four and six months, their babies have four times the risk of pneumonia compared to moms who breastfeed for a year or longer.
Breastmilk contains the nutrients that a newborn baby needs and also transfers disease-fighting antibodies from mother to baby – something that’s very important for the first few months before an infant can be vaccinated. There’s also a growing body of evidence that beneficial bacteria, and perhaps also viruses and fungi, from a mother’s milk and skin can affect her baby’s health.
