SAN DIEGO (KGTV) — One of the country's best spots to lay and in the sand and watch the tide roll in is right in San Diego.Stephen Leatherman, a professor at Florida International University more widely known as "Dr. Beach," has released his annual list of the best beaches in the U.S. Rounding out the top 10 at number nine is San Diego's own Coronado Beach for the second straight year.Tucked along Coronado, the beach is hailed by Leatherman as a local oasis and "toast of Southern California."RELATED: Coronado's Free Summer Shuttle service launches before Memorial Day"Coronado Beach is the toast of Southern California; it is a veritable oasis by the sea, measuring hundreds of yards wide. With its lush subtropical vegetation, unique Mediterranean climate, and fine sparkling sand, beach-goers flock to this beach for great ship-watching and the summer’s warm and mild surf," Leatherman writes.The Hotel del Coronado is also touted for its "Old World elegance" and appeal that it adds to the sandy shores. Coronado Beach was the only California beach to make the list. Topping the beach rankings is Kailua Beach Park in Oahu, Hawaii.So what makes Leatherman the expert? He uses 50 criteria to evaluate beaches, including water and sand quality as well as safety and management. Since 1991, the professor has graded beaches and is regarded as a coastal expert, from storm impacts and coastal erosion to beach health. 1430

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) - On the edge of Balboa Park, parkgoers arrived Wednesday to a fresh layer of graffiti across a popular playground area.Joanne Schara leads a boot camp class at Bird Park at Upas three times a week. After a year of working out there, the things that drew her are now awash in graffiti. "It's just sad to see. You come here because you want a happy space. People bring their kids. People bring their pets. Its beautiful," said Schara.The tagging is everywhere, from the tables and benches and the wall wrapping around the playground area to utility boxes and graffiti on the ground."Doesn't give a good image at all," said Schara.Cathy Lea has lived in the neighborhood for 40 years and takes her dogs to the park twice a day."When I see the graffiti, it's disheartening," said Schara.Lea says every few days, there is more graffiti. On the concrete wall that surrounds the park, there are countless layers of tagging that have been painted over, only to be tagged again."That's not what this park is about," said Lea.On the Nextdoor app, some longtime neighbors posted the current graffiti is the "worst they've ever seen." Lately the graffiti has started to creep into areas previously untouched, including the playground set and the nearby rocks. As the tagging spreads, so does the frustration."It's not the kind of message we want to be sending in North Park," said Lea.Several neighbors have posted on the city's Get It Done app to get it cleaned up. Parkgoers worry it'll be tagged as soon as it's cleaned up. 1542
