Women with large hips will be easy to get asthma.

Is your waist size is appropriate? If not, get ready had asthma. Researchers from the United States found that a large waist women more susceptible to asthma.

Julie Von Behren and his colleagues from the Northern California Cancer Center, Berkeley found that women's waist size greater asthma more susceptible than normal waist size women.

Large waist is usually associated with obesity a disease, but not all women who also had a relatively large waist obesity. There are standard sizes. Researchers also said that the woman waist size more than about 88 cm or 34 inches is at risk of asthma.

"Especially if the woman's obesity, asthma can get worse," said Von Behren was quoted as saying by Reuters on Thursday (8/10/2009).

Von Behren and colleagues surveyed 88,304 women aged 40 to 70 years, and found that obese women get more medical treatment of asthma associated with sustained disease.

As many as 13 percent of survey respondents who are classified as follows obesity with body mass index or body mass index (BMI) is above 30. A total of 1.5 per cent classified as extremely obese with a BMI over 40.

BMI is a standard measure to determine how big or how a normal person's body size according to height ratio and body weight. Normal BMI ranges between 18.5 and 24.9.

Although it is known asthma risk is greater in those who are obese, but other facts found in this study is the woman's waist size large (although not obese) are more susceptible to asthma.

"This study did show the risk of asthma in women who mostly belong to obesity, but there are also those who are big waist, but not considered obese. So that the default is the waist size, whether or not including the normal," said Von Behren.
