SAN DIEGO (KGTV) — New studies are showing that one of the most important risk factors for COVID-19 is weight, including for children.People who are obese are more than twice as likely to wind up in the hospital with COVID-19 as those with normal weight, and 48 percent more likely to die from it, according to a study last month that looked at hundreds of thousands of patients.“Some people have made the argument that the deaths from COVID are just in people with preexisting conditions. Well, this is a preexisting condition that affects a third of the U.S. population in the obese range and another third in the overweight range,” said Dr. Christian Ramers of Family Health Centers of San Diego. “So it’s extremely common.”More than 71 percent of adults are either overweight or obese, according to the CDC. Adults are considered overweight if their body mass index is 25 or higher, and obese if their BMI is 30 or higher.The U.S. has one of the highest rates of obesity in the world, and some experts have theorized it’s one of the reasons why the virus has hit our country harder than others.The risk extends to children as well, who are generally spared from severe cases of COVID-19. Among children hospitalized with the disease, 38 percent had obesity, by far the largest risk factor, according to a CDC study.But what is it about fat that makes the virus worse?There are several theories. People who are obese have blood that clots more easily, one of the main ways COVID-19 kills. Fat cells secrete tiny proteins that cause inflammation, another huge problem with COVID patients that can spiral out of control in what’s called a cytokine storm.Overall, obese people have weaker immune systems.“The theory is that the fat is taking over in certain parts of your body that normally are producing white blood cells,” said Dr. Marsha Blount of Sharp Rees-Stealy Medical Center.Extra fat on the abdomen makes it harder to get air into the lungs, exacerbating conditions like pneumonia. And the extra weight makes it harder to use a ventilator, said Dr. Ramers.On top of all that, people with obesity frequently have other underlying conditions.“Hypertension, diabetes, obesity, fatty liver -- these things are all associated with each other,” Dr. Ramers said. “What we’ve seen is that each of them is related to a poor outcome with COVID.”Studies have shown that simply being overweight increases the risk of COVID-19. A study of nearly 17,000 hospitalized patients in the U.S. found that 29 percent were overweight and another 48 percent were obese.The encouraging news, according to Dr. Blount, is that losing just 5 percent of your weight can have significant benefits. Dr. Blount teaches other physicians how to talk about weight loss with a technique called motivational interviewing.“That 5 percent has been proven time and time again to decrease the risk of getting diabetes. It decreases breast cancer risk for females. It lowers triglycerides and improves HDL, which are different lipid numbers and that thereby decreases your risk of stroke and heart attack,” she said.It can also reduce blood pressure, another major risk factor for COVID, suggesting a little weight loss can go a long way. 3215

SAN DIEGO (KGTV) - President Trump's call for some teachers to be armed is sparking local debate.Linda bought her first handgun three years ago for personal protection. She's a local music teacher at elementary, middle and high schools who applauds the President's idea. "It's a good idea because we're going against violence people doing violent things. I can't protect all 30 of my students with pencils, erasers and rulers," said Linda.RELATED: Trump pushing to 'finally do something' on gunsEric Heins, President of the California Teachers Association, is in town for the state Democratic convention and says schools should not be a war zone. "To try and militarize a student campus by introducing more guns is insane. On a practical level, it wouldn't work," said Heins.He says teachers are simply not trained to deal with shooters armed with assault rifles, trying to figure out who and what to shoot at.RELATED: University in Florida to allow teachers, staff to carry guns through program with sheriff's office"It's a recipe for unintentional disaster," said Heins.But Linda, who owns concealed weapons permits in five states, says teachers can be trained. She's gone through extensive firearms training the last three years."Teachers can be trained to eliminate the threat, to stop a threat," said Linda.Heins says resources would be better spent on counselors, psychologists and other things to address the cause of the violence. Linda says those causes should be addressed, but armed teachers are needed as a final defense. 1566

SAN DIEGO (KGTV) - Nearly 1,000 students and volunteers will work together to clean Mission Beach Thursday as part of this year's Kids' Ocean Day. After removing the litter, students will create an aerial art image that will read "WAVES OF CHANGE" to advocate for a safer, cleaner ocean.Humans deposit eight million metric tons of plastic into the world's oceans every year. Plastics break down into smaller and smaller pieces called microplastics, which are dangerous to both marine life and people. San Diego’s event was coordinated locally by I Love A Clean San Diego (ILACSD). It is one of five happening across the state.DetailsWhen: Thursday, May 24, 2018 from 8:00 a.m- 12:00 p.m 714

SAN DIEGO (KGTV) — More rain arrived in San Diego Wednesday, less than a week after a storm swept through the county, leaving some areas flooded and city crews preparing for the wet weather.In Coronado, on First Street, crews worked to clear pipes near the shoreline. This is a large reason for flooding in the area. Public Services Director, Clifford Maurer, says flooding comes after sand and sediment gets into the storm drain from the high tides.“Some of the outfalls, the pipes that go into the bay or into the open waters have flapper valves on them. So they only allow water to go out, not come in,” says Maurer. “But when the water is above those valves there’s nothing you can do. There’s just nowhere for the water go."RELATED: Check out your daily forecastThe City of Coronado is also offering sandbags to residents. The bags are already filled and can be picked up at four different locations around the island.The City of San Diego is also preparing for the rain. Crews have signs and barricades already lined up in Mission Valley, an area frequent to flooding.Crews are placing bypass pumps in area they expect to flood. “Bypass pumps help relieve some areas of our system that may be overwhelmed with stormwater,” says Anthony Santacroce.RADAR: Live updating San Diego radarFifteen two-person crews that will be out patrolling areas within the city, looking for any storm damage or flooding.Both cities suggest homeowners should make sure the storm drains near their homes are clear of debris, so it doesn’t get swept in with the rain. 1558
