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) — Nearly three-quarters of the students in San Diego County are currently learning from home, and those numbers don’t make a lot of sense to MIT professor Martin Bazant.Bazant is one of the creators of the COVID-19 Indoor Safety Guideline. The free online tool simulates the fluid dynamics of respiratory droplets in various kinds of rooms to show users the risk of different indoor environments.“If you run the numbers for a typical classroom, especially if the students and the teachers are wearing masks, then the amount of time in the room can be very significant,” Bazant said. “Essentially those people could spend a week in the classroom and not have a problem.”Bazant says the six-foot rule that has largely determined which businesses can stay open is overly simplistic. In some cases, he says the rule creates a false sense of security. In other situations, he says it causes the closure of businesses or schools that could safely operate.“If you place nursing home beds six feet apart in a shared room, they are absolutely not safe,” he said. But he said well-ventilated classrooms, with teachers and students in masks, are another story.“It's only the United States where we follow the six-foot rule. That's given by the CDC. The World Health Organization all along has been saying one meter, which is about three feet. If you simply followed the one-meter rule, all our schools would be open, as they are in most of the world right now,” he said.Bazant and his colleague John Bush said they set out to design a tool that would reveal the risk of transmission based on science, not guesswork.Users start by selecting a room type, like a classroom or an airplane. From there, they can control a wide array of variables to dial in the risk, like the room size, the ceiling height, and the ventilation and filtration systems.From there, users can further tune the model by human behavior. How many people are in the room? Are they whispering, shouting or singing? How many are wearing masks?Mask usage is a critical component, Bazant says. The model quickly reveals the challenges of maskless activities in rooms with poor ventilation. Put five people without masks in a 400 square foot room with closed windows, and it becomes unsafe after 33 minutes.Bazant says studies on super spreader events show in indoor environments, the distance from an infected person doesn’t matter. Infected droplets spread and mix throughout the room like second-hand smoke from a cigarette.But with masks trapping droplets and diverting them upwards like a chimney, an environment like an airplane could be safe for several hours, according to the model. With more than 95% of the passengers and crew wearing surgical masks, a Boeing 737 could support 200 people -- around full capacity depending on the configuration -- for 18 hours. 2850

SAN DIEGO (KGTV) - New data by an environmental foundation shows Mission Valley is seeing a surge in homeless.A study by the San Diego River Park Foundation says the number of homeless living along the river has nearly doubled since last October.In October of 2016, volunteers counted 56 homeless encampments along the San Diego River and in October of this year, they tallied 101."The numbers really were surprising," said SDRPF President Rob Hutsel, "an 80% increase is really a lot."San Diego Police Department made 270 arrests in homeless-related crimes in September. Hutsel says the new wave of homeless is likely from the city's crackdowns.The SDRPF has compiled data on the homeless encampments' locations and even the trash they produce. "93.7% of the trash (here) is sourced to homelessness," said Hutsel pointing to the map on his phone.In Orange County, law enforcement has established curfews on certain banks along of the Santa Ana River where they are experiencing a similar issue with transients.Councilman Scott Sherman's office says the city performs sweeps of the riverbed and curfews are a possibility once the area becomes more developed. 1166

SAN DIEGO (KGTV) - On Monday, the California National Guard confirmed that its service members were recently sent to two San Diego nursing homes that needed help treating residents who were sick with COVID-19.“We supplemented their existing staff- their civilian staff- with our medical teams here in the California National Guard,” Lt. Col. Jonathan Shiroma told ABC10 and said that they were deployed at the direction of the California Department of Public Health (CDPH).The National Guard reports that 20 troops were sent to Santee's Stanford Court nursing facility for a week in October and another 20 troops were sent to El Cajon's Villa Las Palmas for two weeks in November.Lt. Col. Shiroma said teams tested patients and staff and offered other supportive care. “Within the Guard we also have many medical professionals so each of the teams were led by either a physician assistant or a registered nurse or an LPN,” he added.“If you have an outbreak, you have staff that has to quarantine and so in order to provide care you want to get people into the building to help with the residents,” Deborah Pacyna with the California Association of Health Facilities told ABC10 News.The CDPH reports that since the start of the pandemic, 50 healthcare workers have tested positive at the El Cajon facility where 91 residents have gotten the virus and 45 healthcare workers have tested positive at the Santee facility where 58 residents have contracted COVID-19.The National Guard said that it doesn't have any current missions in San Diego but it's always ready. “If something comes in the next few weeks and there’s a need in any part of the state, the California National Guard will respond appropriately,” added Lt. Col. Shiroma.ABC10 News reached out to both nursing facilities for comment. We are waiting for a reply. 1829
