Back to school time usually means it's time for a new backpack.Nowadays there are tons of choices in how kids can lug around their belongings. Rolling backpacks, shoulder sling options, or the traditional two-strap pack. But which one is right for them?Will it support their back? Stay together through the school year? Does it look good? These are some of the questions parents grapple with in the middle of shopping aisles.A study by UC San Diego researchers found that children commonly carry about 10 to 20 percent of their body weight in backpacks, which is also the limit recommended by the American Academy of Pediatrics.UCSD researchers tested the correlation between backpack weight and a child's back pain. They tested a group of 8 children and measured spinal pressure at three different amounts of backpack weight meant to mimic 10, 20, and 30 percent of their weight.They found that as the weight of the backpack load increases, back pain in children increases and spinal disc height shrinks as lumbar asymmetry grows.Which brings us back to the original question: How do you make sure a backpack is right for a child? A graphic from the folks at RetailMeNot have outlined how a backpack should rest on a child:Safety strapsBackpack straps are more important than kids think. Shoulder straps should be wide and padded to help distribute the pack's weight evenly, according to the website Healthy Children. Abdominal straps also help distribute weight across the waist, hips, and back.It's also recommended not to wear backpacks on only one shoulder, which shifts all that weight and leads to neck and back pain.Wearing it rightThe top of a backpack should sit one to two inches below the top of the shoulders. Also, the pack should not sit more than four inches below the waistline.The bottom of the backpack should align with the curve of the lower back.Preventing injury on the goWhile at school, its important for kids to be careful while lugging around their backpack. If possible, students should stop by their lockers often to unload any unneeded gear from their backpack. If bending down, kids should use both of their knees while wearing a backpack and not bend at the waist.Learning back-strengthening exercises can also help build up muscles primarily used while carrying weight.Consult a pediatrician if necessaryTalking with your child's doctor about back health is vital. Speak with your child as well about being vocal about back discomfort. And for parents, don't ignore complaints about back pain.If may also be worth speaking with school administrators about lightening the load of work carried around or buying separate textbooks to keep at home. 2740

As vaccinations get underway in the United Kingdom, United States and other rich countries who could afford to pre-purchase doses of the COVID-19 vaccines, researchers warn that about a quarter of the world’s population will be unable to be vaccinated until 2022.There are 13 vaccine manufacturers working on coronavirus vaccines, and they are capable of producing around 6 billion courses of vaccine by the end of 2021.“Just over half (51%) of these doses will go to high income countries, which represent 14% of the world’s population,” researchers from the Johns Hopkins Bloomberg School of Public Health wrote in their report, published in the British Medical Journal."Of the 13 manufacturers, only six have sold to low and middle-income countries,” they noted.At the time of the report, the U.S. had reserved 800 million doses of the vaccine. Japan and Australia, which account for fewer than 1% of the world’s COVID-19 cases, have reserved and potential options to get 1 billion doses.“Even if all 13 of these vaccine manufacturers were to succeed in reaching their maximum production capacity, at least a fifth of the world’s population would not have access to vaccines until 2022,” researchers noted.Covax, a global effort organized by the World Health Organization, had made initial purchases of 300 million vaccine doses. Covax is working to create equitable access to COVID-19 tests, treatments and vaccines for all countries. President Donald Trump’s administration said they would not participate in the effort."This study provides an overview of how high-income countries have secured future supplies of COVID-19 vaccines, but that access for the rest of the world is uncertain," the researchers concluded. "Governments and manufacturers might provide much-needed assurances for the equitable allocation of COVID-19 vaccines through greater transparency and accountability over these arrangements." 1921

As the battle between the United States and California over immigration makes its way in court, the war of words is just beginning.The Justice Department sued California late Tuesday, alleging that state policies that prohibit some cooperation with federal immigration enforcement are unconstitutional.California Attorney General Xavier Becerra fired back hours later, saying his state should not be forced to do the federal job of trying to enforce immigration laws."We're not gonna have them coerce us into doing things that they want us to do simply because they don't want to do it them themselves," he told CNN's Anderson Cooper on Wednesday night.Sessions slams policies 684
