A new British study, involving 500,000 adults, has found that living near fast food restaurants could harm the health of the heart.

These kinds of ready-to-eat food environments typically provide unhealthy foods and drinks, and have been linked to cardiovascular diseases, mostly heart failure. The findings were published in Circulation, an American Heart Association journal.

Heart failure is a condition in which the heart muscle can’t pump enough blood to meet the body’s needs for blood and oxygen. In this case, fluids can accumulate in the lungs, causing shortness of breath. This condition can lead to narrowing the heart arteries and raising blood pressure.

This study is likely the first to assess the association between food environment and heart failure with long-term observation, according to the researchers.

The study involved more than 500,000 adults, ages 37-73 years old, in the UK.

During the research, the team measured the link between living within one-kilometer from three types of food environments — pubs or bars, restaurants or cafeterias and fast-food restaurants.

The study documented nearly 13,000 heart failure cases during a 12-year follow-up period.

The analysis found that a closer proximity and a greater density of ready-to-eat food outlets were associated with a 16% risk of heart failure compared to those with no ready-to-eat food environments near their homes.

It also found that those in the highest density areas of pubs and bars showed a 14% higher risk for heart failure; while those in the highest density areas for fast-food outlets had a 12% higher risk.

Heart failure risk was stronger among participants without a college degree and adults in urban areas without access to formal physical activity facilities such as gyms.

According to the researchers, these findings add to previous studies that have suggested that exposure to ready-to-eat food environments is associated with risks of other disorders, such as Type 2 diabetes and obesity, which may also increase the risk of heart failure.

Authors said the findings suggest that improving access to healthier food environments and physical fitness facilities in urban areas, along with helping more people attain higher levels of education, could reduce the increased risk of heart failure linked to quick-meal options.

Climate change is driving changes in rainfall patterns across the world, scientists said in a paper published on Friday, which could also be intensifying typhoons and other tropical storms.

Taiwan, the Philippines and then China were lashed by the year's most powerful typhoon this week, with schools, businesses and financial markets shut as wind speeds surged up to 227 kph (141 mph). On China's eastern coast, hundreds of thousands of people were evacuated ahead of landfall on Thursday.

Stronger tropical storms are part of a wider phenomenon of weather extremes driven by higher temperatures, scientists say.

Researchers led by Zhang Wenxia at the China Academy of Sciences studied historical meteorological data and found about 75% of the world's land area had seen a rise in "precipitation variability" or wider swings between wet and dry weather.

Warming temperatures have enhanced the ability of the atmosphere to hold moisture, which is causing wider fluctuations in rainfall, the researchers said in a paper published by the Science journal.

"(Variability) has increased in most places, including Australia, which means rainier rain periods and drier dry periods," said Steven Sherwood, a scientist at the Climate Change Research Center at the University of New South Wales, who was not involved in the study.

"This is going to increase as global warming continues, enhancing the chances of droughts and/or floods."

FEWER, BUT MORE INTENSE, STORMS

Scientists believe that climate change is also reshaping the behavior of tropical storms, including typhoons, making them less frequent but more powerful.

"I believe higher water vapor in the atmosphere is the ultimate cause of all of these tendencies toward more extreme hydrologic phenomena," Sherwood told Reuters.

Typhoon Gaemi, which first made landfall in Taiwan on Wednesday, was the strongest to hit the island in eight years.

While it is difficult to attribute individual weather events to climate change, models predict that global warming makes typhoons stronger, said Sachie Kanada, a researcher at Japan's Nagoya University.

"In general, warmer sea surface temperature is a favorable condition for tropical cyclone development," she said.

In its "blue paper" on climate change published this month, China said the number of typhoons in the Northwest Pacific and South China Sea had declined significantly since the 1990s, but they were getting stronger.

Taiwan also said in its climate change report published in May that climate change was likely to reduce the overall number of typhoons in the region while making each one more intense.

The decrease in the number of typhoons is due to the uneven pattern of ocean warming, with temperatures rising faster in the western Pacific than the east, said Feng Xiangbo, a tropical cyclone research scientist at the University of Reading.

Water vapor capacity in the lower atmosphere is expected to rise by 7% for each 1 degree Celsius increase in temperatures, with tropical cyclone rainfall in the United States surging by as much as 40% for each single degree rise, he said.
