Vidyya Medical News Service For 03-February-2001:

The following stories appear in full on today's Vidyya Medical News Service Web site.

Researchers report that dopamine, a brain chemical associated with addiction to cocaine, alcohol, and other drugs, may also play an important role in obesity. In the February 3 issue of The Lancet, scientists from the US Department of Energy's Brookhaven National Laboratory in Upton, NY, report that obese individuals have fewer dopamine receptors and may eat more to try to stimulate the dopamine "pleasure" circuits in their brains.

The most recent government obesity guidelines propose that doctors use body mass index (BMI) to assess patients because the index is simple, correlates to fatness, and applies to both men and women. To determine BMI, weight in kilograms is divided by height in meters, squared. Too difficult for you to calculate? Then try this BMI calculator.

Periodic height and weight measurements are recommended for all patients. In adults, BMI (body weight in kilograms divided by the square of height in meters) or a table of suggested weights e.g., may be used, along with the assessment of other factors such as medical conditions or WHR, as a basis for further evaluation, intervention, or referral to specialists. In adolescents, a BMI exceeding the 85th percentile for age and gender may be used as a basis for further assessment, treatment, or referral. The height (or length if appropriate) and weight of infants and children may be plotted on a growth chart e.g.,[2] or compared to tables of average weight for height, age, and gender to determine the need for further evaluation, treatment, or referral. The optimal frequency for measuring height and weight in the clinical setting has not been evaluated and is a matter of clinical discretion. There is insufficient evidence to recommend for or against determination of the WHR as a routine screening test for obesity.
