Bariatric Surgery and Long-term Cardiovascular Events

Abstract: Context Obesity is a risk factor for cardiovascular events. Weight loss might protect against cardiovascular events, but solid evidence is lacking. Objective To study the association between bariatric surgery, weight loss, and cardiovascular events. Design, Setting, and Participants The Swedish Obese Subjects (SOS) study is an ongoing, nonrandomized, prospective, controlled study conducted at 25 public surgical departments and 480 primary health care centers in Sweden of 2010 obese participants who underwent bariatric surgery and 2037 contemporaneously matched obese controls who received usual care. Patients were recruited between September 1, 1987, and January 31, 2001. Date of analysis was December 31, 2009, with median follow-up of 14.7 years (range, 0-20 years). Inclusion criteria were age 37 to 60 years and a body mass index of at least 34 in men and at least 38 in women. Exclusion criteria were identical in surgery and control patients. Surgery patients underwent gastric bypass (13.2%), banding (18.7%), or vertical banded gastroplasty (68.1%), and controls received usual care in the Swedish primary health care system. Physical and biochemical examinations and database cross-checks were undertaken at preplanned intervals. Main Outcome Measures The primary end point of the SOS study (total mortality) was published in 2007. Myocardial infarction and stroke were predefined secondary end points, considered separately and combined. Results Bariatric surgery was associated with a reduced number of cardiovascular deaths (28 events among 2010 patients in the surgery group vs 49 events among 2037 patients in the control group; adjusted hazard ratio [HR], 0.47; 95% CI, 0.29-0.76; P = .002). The number of total first time (fatal or nonfatal) cardiovascular events (myocardial infarction or stroke, whichever came first) was lower in the surgery group (199 events among 2010 patients) than in the control group (234 events among 2037 patients; adjusted HR, 0.67; 95% CI, 0.54-0.83; P Conclusion Compared with usual care, bariatric surgery was associated with reduced number of cardiovascular deaths and lower incidence of cardiovascular events in obese adults.

Alcohol and macronutrient intake patterns are related to general and central adiposity.

Abstract: Alcohol and dietary fat have high energy densities and may therefore be related to body weight and fat deposition. We studied associations between alcohol and macronutrient intake patterns and general and central adiposity. A population-based cross-sectional study of 524 men and 611 women. The participants answered a dietary questionnaire describing habitual food consumption including intake of alcoholic beverages. Macronutrient intake was analysed in relation to anthropometric measures and dual energy X-ray absorptiometry determined body fat. In women, total alcohol intake was negatively associated with body fat percentage (β:−0.67, P<0.01). In men, total alcohol intake was positively associated with sagittal abdominal diameter (SAD) (β: 0.28, P=0.01). In addition, positive associations were found between intake of alcohol from spirits and body fat percentage (β: 1.17, P<0.05), SAD (β: 0.52, P<0.05) and waist circumference (β: 2.29, P=0.01). In men, protein intake was positively associated with body mass index (BMI) (β: 0.03, P=0.001), body fat percentage (β: 0.04, P<0.05), SAD (β: 0.02, P=0.01) and waist circumference (β: 0.09, P<0.01). Also in men only, negative associations between fat intake and BMI (β: −0.03, P<0.01), SAD (β: −0.02, P<0.05) and waist circumference (β: −0.05, P<0.05) were found. Alcohol intake was inversely associated to relative body fat in women whereas spirits consumption was positively related to central and general obesity in men. Macronutrient intakes, particularly protein and fat, were differently associated with obesity indicators in men versus women. This may reflect a differential effect by gender, or differential obesity related reporting errors in men and women.
