Office work bad for your health: Office work is the new smoking, helping to kill millions of people because of increased physical inactivity, a new study has found. The study, which appeared in the Lancet journal, said sitting for at least eight hours a day could increase the risk of premature death by up to 60% and was posing as great a threat to public health as smoking. Inactivity, the study said, was linked to an increased risk of heart disease, diabetes and some cancers and was associated with more than five million deaths a year. Increased physical activity lowers the risk of at least 13 cancer types.
The researchers analyzed data from more than a million people in 16 studies, and warned that too little was being done to tackle the pandemic of physical inactivity. The good news is doing at least an hour of physical activity a day such as walking or cycling can eliminate this increased risk of death. “For many people who commute or have office jobs, there is no way to escape sitting for prolonged periods of time. For these people in particular, we cannot stress enough the importance of getting exercise, whether it’s getting out for a walk at lunchtime, a run in the morning or cycling to work.
An hour of physical activity a day is ideal, but if this is unmanageable, then doing some exercise each day can help reduce the risk,” said lead author Ulf Ekelund of the Norwegian School of Sports Sciences. “This lack of physical activity is the new smoking,” said Jonathan Broomberg, CEO of Discovery Health, who added that fast-rising numbers of people with diabetes, high blood pressure and heart disease caused by an unhealthy lifestyle were taking a toll on medical aids. –Times Live
Walking for Health: Is it time to rethink traditional work meetings? Replacing a seated work meeting with a walking meeting can increase workers’ physical activity and lead to positive health effects, according to researchers from the University of Miami’s Miller School of Medicine. As part of a study, the researchers recruited 17 workers who led weekly meetings. The workers agreed to wear an accelerometer to track their physical activity at work during a three-week period. They also adhered to guidelines for conducting meetings and note-taking while walking. The protocol included following a set route and walking for at least 30 minutes per meeting.
Results showed that, by the third week, participants had increased their moderate-vigorous physical activity to 117 minutes – up from 107 the first week and 114 the second week. Walking meetings and other interventions to increase physical activity are necessary to “counter the negative health effects of sedentary behavior,” Alberto J. Caban-Martinez, the study’s principal investigator and assistant professor of public health sciences, said in a press release.
Brisk walking for as little as 15 minutes per day can increase a person’s life expectancy by up to three years, researchers said. “Walking is known to have tremendous health benefits,” Hannah Kling, lead study author and project director, said in the release. “Having sedentary, white-collar workers consider walking meetings feasible suggests that this intervention has the potential to positively influence the health of many individuals.” The study was published June 23 in the journal Preventing Chronic Disease. –Safety & Health
Diet & Health – Extra “good fats” from nuts and olive oil in a Mediterranean diet may help older adults lose weight, or at least avoid gaining it, a Spanish study suggests. “Our hypothesis is that not all fats are the same; we have to differentiate fats from vegetables and fats from animal sources,” said lead study author Dr. Ramon Estruch of the University of Barcelona. “Vegetable fat such as extra virgin olive oil and nuts help to reduce body weight when these foods are consumed in a healthy diet such as a Mediterranean diet,” Estruch added by email.
A Mediterranean diet typically includes lots of fruits, vegetables, whole grains, legumes and olive oil. This diet also tends to favor lean sources of protein like chicken or fish over red meat, which contains more saturated fat. While some previous research has linked a Mediterranean diet to weight loss and a reduced risk of heart disease and some cancers, scientists haven’t conclusively proven that the diet itself is responsible, rather than other lifestyle choices made by people who eat this way.
For the current study, Estruch and colleagues randomly assigned 7,447 older adults at risk for cardiovascular disease to follow one of three diets: a Mediterranean diet supplemented with one liter (about 34 fluid ounces)of extra virgin olive oil a week, a Mediterranean diet supplemented with 30 grams (1 oz) of nuts a day, or a low-fat diet. At the start of the study, the men were 55 to 80 years old and the women were 60 to 80. All of them had either diabetes or three or more other risk factors for cardiovascular disease such as a smoking habit, elevated blood pressure or high cholesterol.
None of them were told to restrict calories or exercise during the study. After almost five years, people in all three groups had slightly reduced body weight but the change was bigger with the two groups assigned a Mediterranean diet, researchers report in The Lancet Diabetes and Endocrinology. People assigned to follow a Mediterranean diet supplemented with nuts lost 0.08 kilograms (less than half a pound) more weight than the group on the low-fat diet after five years, the study found.
Those on the Mediterranean diet with added olive oil, lost 0.43 kilograms (almost one pound) more weight than participants on the low-fat diet. Researchers also looked at waist circumference over the five years and found little difference between the people on the Mediterranean diet with extra nuts and the participants assigned to a low-fat diet. The group assigned to a Mediterranean diet with added olive oil had a slightly smaller increase in waist size than the low-fat diet group. –Fox News
