Smoking doubles stroke risk in younger women!


By Will Dunham

WASHINGTON (Reuters) - Younger women who smoke have more than double the risk of stroke compared to nonsmokers, with the heaviest smokers among them having nine times the risk, according to a U.S. study published on Thursday.

The research assessed stroke risk in women 15 to 49 years old who smoked cigarettes. Current smokers were 2.6 times as likely to have a stroke than women who never smoked, according to researchers led by Dr. John Cole of the University of Maryland School of Medicine in Baltimore.

Women who smoked the most faced the highest increased risk, said the study, published in the American Heart Association's journal Stroke.

For example, women who smoked 21 to 39 cigarettes a day had a risk of stroke 4.3 times higher than a nonsmoker, while those who puffed at least two packs a day -- 40 cigarettes -- had a stroke risk 9.1 times higher than a nonsmoker.

It has been known for a long time that smoking increases the risk of stroke, along with many other health dangers such as lung and other types of cancer, lung disease and heart disease.

But Cole said less was known about how stroke risk was affected by the number of cigarettes a person smokes.

Strokes typically occur in people older than this study population but the research demonstrated that, even in younger women, stroke risk is greatly increased.

"The more you smoke, the more likely you are to have a stroke," Cole said in a telephone interview. "Certainly quitting is the best thing you could do. But cutting back does offer some benefit." The researchers tracked 466 women in the United States who had already had a stroke and 604 women who had not had a stroke who were of similar age, race and ethnicity.

About a fifth of U.S. women ages 18 to 24 are current smokers, the researchers said.

Cole said he is planning a similar study focusing on stroke risk in younger male smokers.

Why Disasters Are Getting Worse?

By: AMANDA RIPLEY Thu Sep 4, 12:40 PM ET In the space of two weeks, Hurricane Gustav has caused an estimated $3 billion in losses in the U.S. and killed about 110 people in the U.S. and the Caribbean, catastrophic floods in northern India have left a million people homeless, and a 6.2-magnitude earthquake has rocked China's southwest, smashing over 400,000 homes. If it seems like disasters are getting more common, it's because they are. But some disasters do seem to be affecting us worse - and not for the reasons you may think. Floods and storms have led to most of the excess damage. The number of flood and storm disasters has gone up by 7.4% every year in recent decades, according to the Centre for Research on the Epidemiology of Disasters. (Between 2000 and 2007, the growth was even faster - with an average annual rate of increase of 8.4%.) Of the total 197 million people affected by disasters in 2007, 164 million were affected by floods. It is tempting to look at the line-u...

How to boost your immune system

The old saying, “An apple a day can keep the doctor away,” may have truth behind it after all. Eating nourishing foods rich in certain vitamins can help your immune system fight off illness. We talked to registered dietitian Julia Zumpano, RD, LD for a closer look at these vitamins, what foods you can find them in and how they can help keep you healthy. Here’s what she had to say: Vitamin C is one of the biggest immune system boosters of all. In fact, a lack of vitamin C can even make you more prone to getting sick. Foods rich in vitamin C include oranges, grapefruits, tangerines, strawberries, bell peppers, spinach, kale and broccoli. Daily intake of vitamin C is essential for good health because your body doesn’t produce or store it. The good news is that vitamin C is in so many foods that most people don’t need to take a vitamin C supplement unless a doctor advises it. Vitamin B6 is vital to supporting biochemical reactions in the immune system. Vitamin B6-rich foods incl...

Banks Boost Customer Fees to Record Highs

by Jane J. Kim Thursday, November 13, 2008provided by: theworldstreetjournal.com Bounced Checks, Overdrafts and ATM Use All Cost More; Penalizing Repeat Offenders Banks are responding to the troubled economy by jacking up fees on their checking accounts to record amounts. Last week, Citigroup Inc.'s Citibank started charging some customers a new $10 "overdraft protection transfer fee" to transfer money from a savings account or line of credit to cover a checking-account shortfall. Citibank had already raised foreign-exchange transaction fees on its debit cards and added minimum opening deposit requirements for its checking accounts. Over the past year, J.P. Morgan Chase & Co.'s Chase, Bank of America Corp., and Wells Fargo & Co. have boosted the fees they charge noncustomers who use their automated teller machines to as much as $3 per transaction. With all these changes, the average costs of checking-account fees, including ATM surcharges, bounced-check fees a...
