be deprived of weight now, and your heart will thank you later. At least that's what a new study published in the British Medical Journal hints It seems that weight history from middle age, is an important factor in assessing one's risk of developing coronary heart disease in late middle and antique age, regardless of the person's weight at that time.

While the incentive to trim our waistlines is frequently more vanity-driven than health-driven, the evidence continues to rise in support of the fact that obesity is hazardous to our health, especially our hearts.

The heart disease epidemic

The statistics exhibit to unfortunately, that Americans and heart disease go on hand in hand:

* An American dies of cardiovascular disease each 33 seconds. That is more than 954000 deaths or more than 42 percent of all deaths each year.

* Since the year 1900 cardiovascular disease has been the number-one killer in the United States each year but one (1918).

* 13490000 Americans have coronary heart disease.

* Heart attack is the single largest killer of Americans, including men and women

* About each 20 seconds an American will experience a new or recurrent heart attack, and about each minute someone will die from one

While there are many factors that contribute to one's risk of developing coronary heart disease, obesity is certainly single in kind of them. In their introduction, the authors of this consideration including U.S. National Institutes of Health researcher Tamara B Harris, et al, agree, saying that obesity is a significant contributor to the risk of developing coronary heart disease -- as well-as; not only-but also; not only-but; not alone-but in younger people and in folks of about 65 years of age.

They note, however, that irregularly enough, in studies of weight change among older race -- that is, those from one side of to the other age 65 -- weight los rather than weight gain was associated with coronary heart disease. While the precise reason for this phenomenon is unclear, Harris, et al., say that "sustained weight los in aged age is unlikely to be voluntary and may cast reproach other diseases, some of which might increase the risk of thromboembolic [the clotting of a life-blood vessel] events." In other words, the weight los was not to be ascribed in most cases, to as it is factors as physical activity, further to diseases and problems, as it is as diabetes and stroke, and to the degenerative processe associated with them.

The objective of this particular inquiry was to evaluate the risk of late-life coronary heart disease as it relates to being overweight in late middle or not new age and to assess whether weight change modifies this risk.

The study

This study's participants were actually a cohort taken from a larger longitudinal subject of attention -- the epidemiological follow-up investigation of the national health and nutrition examination view I (NHANES I). This enabled the researchers to have access to a history of the participant's visible form [i]or[/i] frame mass index (BMI) records.

BMI is calculated by way of dividing weight in kilograms through height in meters squared (kg/m2) To transpose pounds to kilograms, multiply by the agency of 2.205; to convert inches to meter divide on 39.36.

In her part The New Maximize Your material substance Potential, Joyce D. Nash, PhD says that although, traditionally, a BMI between 20 and 27 was considered acceptable, modern research suggests that even a BMI between 25 and 30 is indicative of mild obesity. Moderate obesity is defined as a BMI of 30 to 35 and stern obesity is marked by a BMI of 35 or greater.

Weight change among the participants was calculated as percentage change from 1971-75 to 1982-84 which allowed for comparison of equivalent change among clan of different initial weights. Three categories of weight change were created: gain of 10 percent or more, gain of les than 10 percent to los of les than 10 percent and los of 10 percent or more. Those whose weight remained the chiefly stable (gain or loss of les than 10 percent) were used as the intimation group.

The flows showed:

* More women than men wasted 10 percent or more material substance weight between the first and secondary measures, while about equal proportions gained 10 percent or more.

* A greater BMI in the 1971-75 measurement was associated with a 70 percent increase in the risk of developing coronary heart disease for as well-as; not only-but also; not only-but; not alone-but men and women, while heavier passing from hand to hand BMI was not associated with an increased risk of coronary heart disease in either sex

* Weight los was associated with an increased risk of coronary heart disease for the pair women and men, while weight gain was not associated with increased risk.

* For men and women combined, the risk associated with present weight was modified by history of weight change. Risk of coronary heart disease was increased among heavier the bulk of mankind who had gained weight and among thinner folks who had lost weight.

What it all means

While the findings of this meditation do indicate that their is indeed a link between middle-age obesity and coronary heart disease later in life, the accrues are less cut and dried than individual might expect. Here is a summary of what the authors describe as the study's [i]clavis[/i] messages:
