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 protests reached unprecedented levels on Wednesday, bolstered by professional athletes sitting out sporting events, Republicans offered a full-throated backing of police officers during Night 3 of the Republican National Convention.Featured on Wednesday, Michael McHale of the National Association of Police Organizations, went after the Biden campaign, who he claimed is “anti-police.”“I’m proud that the overwhelming majority of American police officers are the best of the best and put their lives on the line without hesitation. And good officers need to know their elected leaders and the department brass have their backs,” said McHale.Meanwhile, unrest unfolded in Kenosha, Wisconsin, following the shooting of Jacob Blake. Blake was shot seven times by Rusten Sheskey, a Kenosha Police officer who has since been placed on administrative leave.Investigators, speaking for the first time since Sunday's incident, declined to press charges on Wednesday against Sheskey despite the massive protests. Joining in the protests were athletes from the NBA, MLB and MLS, who took the unprecedented step to boycott playing as players demanded action against the officer who shot Blake. As the fourth night of demonstrations ensued in Kenosha, amid a summer of protests demanding changes to policing, Sen. Marsha Blackburn, R-Tenn., decried protests.“I'm talking about the heroes of our law enforcement and armed services. Leftists try to turn them into villains. They try to cancel them. But I'm here to tell you that these heroes can’t be canceled.,” Blackburn said.Mike Pence, accepting the GOP nomination for a second term as vice president Wednesday, tried to thread the needle between offering support for law enforcement while understanding the pain many Black Americans are experiencing. "We don’t have to choose between supporting law enforcement and standing with African American neighbors," Pence said.While Republicans multiple times claimed that Biden would defund policing, Biden has said he opposes defunding police departments. 2052
