A friend of mine is in great physical shape but her husband (we’ll call him “Mr. B”) has gained 40 pounds since they were married five years ago. He also has familial hypercholesterolemia, and several of his relatives have had heart attacks at young ages. Mrs. B is distraught – she is worried about her husband’s health, and has tried to gently nudge him towards healthier eating habits and regular exercise (as well as taking a statin for his cholesterol). Unfortunately, the nudges were received as nagging, and a wedge has formed between them in their relationship.
Last week my friend planned a trip to a primary care physician in the hopes that he would educate Mr. B about the dangers of being overweight and not treating his high cholesterol. “Surely Mr. B will listen to an expert” she thought, “then perhaps he’ll realize that he has to change his behavior.”
Unfortunately, the primary care physician didn’t offer any health counseling to Mr. B. Not only did he not mention that Mr. B should lose weight, but he didn’t provide any warnings about the dangers of untreated, very high cholesterol levels. He merely reported that Mr. B’s total cholesterol was 300, and that a statin was indicated.
Mrs. B was crestfallen. She was depending on the physician’s authoritative input to help her come up with a strategy to steer her husband towards better health. Now Mr. B was left with the impression that things were more-or-less ok, and that his wife’s concerns were exaggerated. Read more »

Obesity contributes to cardiovascular risk no matter where a person carries the weight, concluded researchers after looking at outcomes for nearly a quarter-million people worldwide.
Body mass index, (BMI) waist circumference, and waist-to-hip ratio do not predict cardiovascular disease risk any better when physicians recorded systolic blood pressure, history of diabetes and cholesterol levels, researchers reported in The Lancet.
The research group used individual records from 58 prospective studies with at least one year of follow up. In each study, participants were not selected on the basis of having previous vascular disease. Each study provided baseline for weight, height, and waist and hip circumference. Cause-specific mortality or vascular morbidity were recorded according to well defined criteria.
Individual records included 221,934 people in 17 countries. In people with BMI of 20 kg/m2 or higher, hazard ratios for cardiovascular disease were 1.23 (95 percent CI, 1.17 to 1.29) with BMI, 1.27 (95 percent CI, 1.20 to 1.33) with waist circumference, and 1.25 (95 percent CI, 1.19 to 1.31) with waist-to-hip ratio, after adjustment for age, sex, and smoking status. After adjusting for baseline systolic blood pressure, history of diabetes, and total and HDL cholesterol, corresponding hazard rations were 1.07 (95 percent CI, 1.03 to 1.11) with BMI, 1.10 (95 percent CI, 1.05 to 1.14) with waist circumference, and 1.12 (95 percent CI, 1.08 to 1.15) with waist-to-hip ratio.
BMI, waist circumference, or waist-to-hip ratio did not importantly improve risk discrimination or predicted 10-year risk, and the findings remained the same when adiposity — the carrying of adipose tissue (fat) — measures were considered. Read more »

Most people know that the U.S. is struggling to contain a surging epidemic of obesity, and that the problem is most acute among African-Americans. Whereas about 27 percent of all adult Americans are obese (defined as having a body mass index of 30 or more), fully 37 percent of African-American adults are obese, and that number jumps to an appalling 42 percent among African-American women.
Over the years, public health officials have provided evidence that socioeconomic and cultural factors drive this racial disparity. Now, a new study suggests there is another reason as well: Obese African-Americans receive less obesity-related counseling than their white counterparts, and it matters not whether the physicians they see are African-American or white.
To reach these conclusions, Sara Bleich and colleagues from the Johns Hopkins School of Public Health used clinical encounter data from the 2005–2007 National Ambulatory Medical Care Surveys (NAMCS). The sample included 2,231 visits involving African-American and white obese people who were at least 20 years old and who visited family practitioners and internists that were either African-American or white. Asian and Hispanic patients and physicians were excluded from the study because their numbers were too small to permit hypothesis testing.
For each encounter in the study, the scientists determined whether the patient received guidance on weight reduction, diet and nutrition, or exercise from his or her physician. Read more »
