Soon after the pandemic began a year ago, Americans began joking about the dreaded “quarantine 15”, worried that they might gain weight while staying locked in homes with food stores, computer screens and bi Boulders stick to Netflix.
The concern is genuine, but assessing the scope of the problem is a challenge. Surveys that simply ask people about their weight are highly unreliable, and many medical journeys have been virtual.
Now a much smaller study using objective measures – measuring weight with Bluetooth-connected smart scales – suggests that adults under shelter-in-order Gained more than half a pound every 10 days.
That translates to about two pounds a month, Drs. Gregory M. Marcus, senior author of the research paper, published Monday at the PAR-reviewed JAMA Network Open. He said that Americans who maintained their lockdown habits could easily gain 20 pounds in a year.
“We know that weight gain is already a public health problem in the US, so anything that makes it worse is definitely related, and shelter-in-place orders are so ubiquitous that the sheer number of people affected by it makes it Extremely relevant, ”Dr. Marcus, a cardiologist and professor of medicine at the University of California at San Francisco.
Although it is nearly impossible to generalize based on the study – which included fewer than 300 people scattered across the United States – all participants were regularly tracking their weight.
Dr. Marx said that many of these people were losing weight, as asylum-related orders were issued in their states. He added, “It is appropriate that these individuals are more commonly associated with their health, and are more disciplined and on top of things.” “It turns out that we can be underestimated – that this is the tip of the iceberg.”
Excess weight is associated with a greater risk of developing more severe Kovid-19 disease, and the United States already has the highest rate of overweight and obesity in the world. Some 42 percent of American adults over the age of 20 have obesity, as defined by the body mass index, while the other 32 percent of Americans are only overweight.
The risk of serious illness has also been documented in young adults who are overweight or obese. Many states are giving priority to people who are overweight or obese for vaccination, as well as those who have other chronic conditions such as diabetes or high blood pressure.
The new study analyzed data received from 269 participants who were involved in the ongoing cardiology study, the Health Ehart Study. He reported voluntarily measuring weights with Bluetooth-connected smart scales and weighed himself regularly; The researchers collected 7,444 weight measurements over a four-month period, an average of 28 weight measurements from each participant.
The group was not nationally representative in any way, so the results are not generalizable: about three-quarters were White, and just 3.5 percent identified as Black or African-American; About 3 percent identify as Asian-American. The average age was 51, and they were divided equally between men and women.
Participants were from 37 states and the District of Columbia. The researchers analyzed the weight measurements taken between February 1, 2020, and June 1, 2020, to see the change in weight before and after the issuance of the asylum-in-order order for each state.
While the participants had lost most pounds before the order was issued, their weight increased rapidly at a rate of about six-tenths of a pound every ten days after 10 days of the order, regardless of where they were in the country. And no matter what the medical condition.
Lockdown definitely has an effect on dietary patterns, what people eat and how often they eat. But the sanctions also stopped Hamdam Physical activity that is part and parcel of daily lifeThe researchers said.
“If you think of people coming and going, even running to the metro or bus stop, or a letter while stepping into the post office, or stopping at the store – we do the non-exercise activities of daily life. I burn a lot of calories: “said Lean Redman, a professor of clinical physiology at the Pennington Biomedical Research Center, part of Louisiana State University.
His research found that people were eating a healthy diet in the early days of the bandh, but were more sedentary.
An earlier study by UCSF researchers calculated the daily steps tracked by a smartphone, among about half a million people from about 200 countries. The number of steps people took It dropped 27 percent a month after the World Health Organization declared an epidemic.
Concern about exercise also extends to children who are known to pack on unhealthy pounds during summer days when they are not in school. The risk is even greater for white children than for Hispanic and black children, the author of a recently published paper by Andrew G. Rundley, an associate professor of epidemiology at Columbia University’s Mailman School of Public Health Worry that school will be closed Current racial health disparities.
“We argued that dropping out of school, which we thought would last six months and last longer, would be like summer vacation, but worse, because everyone would be loaded onto a shelf-stable calorie-rich meal , And stay indoors and don’t go out, “he said. “Everything that makes heat dangerous for children will be increased by lockdown.”
