Being obese and commuting by car can be a deadly mix, a new study warns. Researchers analyzed data on more than 163,000 adults, aged 37 to 73, in the United Kingdom. The participants were followed for an average of five years. Compared to people of normal weight who walked or cycled to work (active commuters), those who were obese and commuted by car had a 32% higher risk of early death from any cause; twice the risk of dying from heart disease; and a 59% higher risk for non-fatal heart disease. Obesity was defined by the researchers as having a body mass index (BMI) of more than 30. BMI is a measure of body fat based on height and weight. As an example, a person who is 5 feet, 9 inches tall weighing 204 pounds has a BMI of just over 30. The study also found that overall risk of early death among obese people who were active commuters was similar to that for active commuters whose weight was normal. That suggests cycling or walking to work could reduce the harmful effects of obesity. However, the risk of heart disease was still 82% higher for obese active commuters than for normal-weight active commuters, researchers said. “Our findings, if causal, suggest that people with overweight or obesity could potentially decrease the risk of premature mortality if… read on >

(HealthDay News) — Thousands of young children face injury or death in car accidents each year. Proper use of car seats can keep children safe in the event of a crash, says American Academy of Pediatrics (AAP). The AAP provides these guidelines for choosing car seats: All infants and toddlers should ride in a rear-facing seat. After outgrowing a rear-facing seat, a child should ride in a forward-facing seat with a harness. After outgrowing the forward-facing seat, a child should use a belt-positioning booster seat. Children old enough and large enough to fit correctly should use seat belts. All children under 13 years of age should ride in the back seat.

Traffic pollution causes about 4 million new asthma cases in children worldwide each year, new research shows. Two-thirds of these kids live in urban areas, according to the study by researchers at George Washington University in Washington, D.C. “Our findings suggest that millions of new cases of pediatric asthma could be prevented in cities around the world by reducing air pollution,” said senior study author Susan Anenberg. She is an associate professor of environmental and occupational health at the university’s Milken Institute School of Public Health. Between 2010 and 2015, about 4 million children in 194 countries developed asthma each year due to exposure to nitrogen dioxide (NO2) air pollution, the researchers said. NO2 mainly comes from vehicle exhaust. “Improving access to cleaner forms of transportation, like electrified public transport and active commuting by cycling and walking, would not only bring down NO2 levels, but would also reduce asthma, enhance physical fitness, and cut greenhouse gas emissions,” Anenberg said in a university news release. About 13% of asthma incidence in children is linked with NO2 pollution, the study authors noted. But among 92 of 125 major cities included in the new study, NO2 pollution accounted for more than 20% of childhood asthma cases, the findings showed. The 10 cities with the highest rates included eight in China (with rates reaching 37% to 48%), as well… read on >

The risks of using voice-based technology in your car may be greater than you think. Many consider this technology safer than using their hands to operate devices while driving, but it’s not risk-free, the AAA Foundation for Traffic Safety warns. Mental distractions can last as long as 27 seconds after drivers use voice-assisted technology to dial, change music or send a text message. At 25 mph, a car travels the length of nearly three football fields during this short time. “Just because your eyes are on the road and hands are on the wheel, does not mean you are focused on driving,” David Yang, the foundation’s executive director, said in a AAA news release. “Research from the AAA Foundation shows that mental distractions resulting from talking, texting, or programming navigation can last longer than you think and lead to crashes,” he cautioned. The risk of a crash is up to four times higher for drivers who talk on a cellphone, and up to eight times higher for those who text behind the wheel, the researchers said. Even so, nearly half of drivers report talking on a handheld phone while driving recently, and about one-third have sent a text or email, according to the foundation. The risky behavior persists even though nearly 58% of drivers say talking on a cellphone behind the wheel is a very… read on >

Spring break may mean sun and fun for lots of college kids, but it doesn’t mean they can forget about contact lens care, experts say. Your risk of eye infections increases if you wear contacts and do things such as sleep in them, shower or swim with them in, and not wash your hands before handling them — all of which are more likely to happen when you’re busy enjoying your spring break. The American Academy of Ophthalmology, American Academy of Optometry and the U.S. Centers for Disease Control and Prevention offer the following contact lens safety tips for travelers: Pack a spare pair of glasses. Take out your contact lenses before jumping into the water at a beach or pool. Take your contact lenses out before bed, even if you’re up late. Bring enough contact lens supplies with you on your trip. Don’t top off by adding new solution to old. Never wear contact lenses that were not prescribed to you, especially decorative lenses sold at souvenir shops. Always wash your hands with soap and water before touching your contact lenses. Remove your contact lenses and call an eye doctor immediately if you experience redness, pain, tearing, discharge or swelling of your eyes, as well as increased light sensitivity or blurred vision. “Most people don’t think of contact lenses as a medical device, but… read on >

(HealthDay News) — Foodborne illness is often preventable, yet millions of people become sick from this, says the World Health Organization. The organization’s “Five Keys to Safer Food” are: Wash your hands before handling/consuming food. Separate raw and cooked food. Cook food thoroughly. Keep food below 5 degrees C or above 60 degrees C. Avoid tap water and unpeeled fruits/vegetables while outside the United States. Before leaving home, WHO also recommends speaking with your doctor about diseases at your destination. He or she may recommend preventative measures, such as vaccinations.

A healthy democracy means better health for its citizens, a new study claims. Researchers analyzed political, economic and population health data from 170 countries over 46 years — 1970 to 2016. They concluded that as levels of democracy increased, governments spent more on health, irrespective of their country’s economic situation. “The results of this study suggest that elections and the health of the people are increasingly inseparable,” said study leader Thomas Bollyky, of the U.S. Council on Foreign Relations. “Without the same pressure or validation from voters or foreign aid agencies, autocratic leaders have less incentive than their democratic counterparts to finance the more expensive prevention and treatment of heart diseases, cancers and other chronic illnesses,” he added. The researchers concluded that democracy supported by regular free and fair elections not only increases health but potentially reduces deaths from several noncommunicable diseases and traffic injuries. Specifically, they found that average adult life expectancy (after controlling for HIV/AIDS) improved faster — an average of 3 percent over 10 years — in countries that switched to democracy between 1970 and 2015, compared to those that did not adopt democracy. The causes of death most affected by a switch to democracy — heart disease, tuberculosis, traffic injuries and several other noncommunicable diseases — cause more than one-quarter of all the death and disability in people 70 and younger… read on >

The switch to Daylight Saving Time can increase the risk of driver fatigue and crashes, but there are a number of ways to reduce the danger, an expert says. “Any time change can exacerbate drowsiness because your internal clock has not adjusted to the time change. This can lead to disruptions in sleep until your body adjusts, which can take a few days to a week,” said Jeff Hickman, a research scientist at the Virginia Tech Transportation Institute in Blacksburg. After clocks spring ahead one hour at 2 a.m. on Sunday, try to avoid driving during rush hours and in early morning, when crash risk increases, he suggested. Driving between 2 a.m. and 4 a.m. is particularly dangerous, because your circadian rhythm is at its lowest during this two-hour period. Drivers should try to sleep at least seven to eight hours, Hickman said. But one night of good rest may not be enough if you have had several sleepless nights. If that’s the case, you’ll need several nights of restful sleep to compensate. Watch for signs of drowsy driving, including slow eyelid closures, yawning, gentle swaying of the head, fidgeting in the seat, trouble staying in your lane, difficulty maintaining speed and slow reactions, Hickman said in a Virginia Tech news release. Be extra careful in situations that increase drowsiness, including driving alone, monotonous road… read on >
