The gap in life expectancy between black and white Americans is smaller than it has ever been, thanks largely to a decline in the number of deaths resulting from heart disease and HIV infection, a new analysis has found. That's the good news. The bad news is that the gap is still large: A black baby boy born today can expect to live 5.4 fewer years, on average, than his white counterpart, and a black baby girl will die 3.7 years earlier, on average, than her white counterpart. What's more, the narrowing of the gap between 2003 and 2008 is due in part to a troubling development among whites: They are more likely than in the past to die from overdoses of powerful prescription medications like OxyContin and Vicodin, along with other unintentional poisonings.

Babies born in the United States in 2009 have a record life expectancy of about 78 years and 2 months. That's the latest from preliminary figures released Wednesday from the Centers for Disease Control and Prevention. Life expectancy didn't rise all that much from 2008 -- just two-tenths of a year for men to 75.7 years and one-tenth of a year for women to 80.6 years. The National Vital Statistics Reports also show that white women have the highest life expectancy followed by black females, white males and black males.

Life expectancy is up in the United States. We know this because the headlines have been trumpeting the news floating around all week. So maybe it’s time for a closer look at what factors affect life expectancy -- and what you can do about it. The National Vital Statistics Reports from the Centers for Disease Control and Prevention points to these causes of death (no surprises if you've been keeping up on health news). Heart disease is the No. 1 cause (616,067) followed by cancer (562,875)

A new study links even small reductions in fine particle air pollution to increased life expectancy. Researchers who compared data from 545 counties across the U.S., including many in California, found that a drop in fine particulate matter , known as PM2.5, between 2000 and 2007 corresponded with an average rise in life expectancy of 0.35 of a year. The study, led by researchers at the Harvard School of Public Health, is described as the largest to date to find public health benefits from ongoing reductions in U.S. air pollution levels.

BEIJING - Life expectancy is 5.5 years lower in northern China than in the south because of heavy air pollution, a study examining 20 years of data concludes. The research -- published Monday in the Proceedings of the National Academy of Sciences by four economists in China, the United States and Israel - examined air quality readings collected in 90 Chinese cities from 1981 to 2000, and compared them with mortality data collected from 145 locations from 1991 to 2000. Other studies have established strong correlations between air pollution and poor health and attempted to quantify the resulting loss of life in China.

So, what's it worth to lace up those sneakers and break a sweat for about 30 minutes a day? About 3.5 extra years of life, on average - and about 4.2 additional years for those willing to step up the intensity or put in closer to an hour a day of brisk walking or its equivalent, according to a new study. Even for the severely obese - those with a body mass index above 35 - exercising for about 2.5 hours a week at moderate intensity or for 75 minutes at vigorous levels puts average life expectancy a notch above that of a normal-weight person who is sedentary, the research shows.
