ABSTRACT
BACKGROUND:
Weight loss is recommended among overweight survivors of myocardial infarction (MI). This study describes patterns of weight change among overweight patients with MI and identifies factors associated with weight change.METHODS:
A prospective cohort of 1253 overweight or heavier (body mass index [BMI] > or = 25 kg/m2) post-MI patients were enrolled in the 19-center PREMIER study and followed up for 1 year to determine changes in weight. Patients were categorized at 1 month as overweight (BMI = 25-29.9 kg/m2), obese (BMI = 30-39.9 kg/m2), or morbidly obese (BMI > or = 40 kg/m2). Unadjusted percent weight change was assessed at 1 year, and multivariable linear regression was used to identify independent correlates of change.RESULTS:
Mean weight change was -0.2% and varied by the severity of baseline obesity (+0.4% for overweight patients, -0.5% for obese patients, and -3.7% for morbidly obese patients [P < .001]). Multivariable analyses revealed the following to be significantly associated with weight change depression 1 month post-MI (+2.7%, P = .001), lack of health insurance (+2%, P = .01), smoking cessation 1 month post-MI (+2.7% vs current smokers, P < .001), morbid obesity (+4.7% vs overweight patients, P < .0001), and increasing age (-0.8% per decade, P = .001). An interaction between smoking cessation and weight class was detected in that overweight patients who quit had a mean increase of 5.3% (95% CI 3.1%-7.4%), whereas no significant change was observed among obese and morbidly obese patients who quit.CONCLUSIONS:
Although post-MI patients had negligible weight loss over 1 year, several sociodemographic, clinical, and lifestyle characteristics were associated with weight change. New, targeted interventions will likely be needed to improve weight management after an MI.
