title: Three-year measured weight change in the African American health study.
abstract: OBJECTIVE
  This study examines 3-year weight change in African Americans.
  
  
  METHODS
  Nine hundred and ninety-eight participants 49 to 65 years old were assessed at baseline and 3 years later. Weight was measured, and weight change was defined as clinically meaningful increases or decreases (+/- 5 kg). Potential risk factors were investigated using multinomial logistic regression.
  
  
  RESULTS
  In-home measured weights were available for 752 participants (75%): 504 (67%) had stable weights, 131 (17%) gained more than 5 kg, and 117 (16%) lost more than 5 kg. Among all participants, the risks for weight gains were cancer, chronic obstructive pulmonary disease, lower income, and Medicaid status; the risks for weight losses were angina, cancer, high measured systolic blood pressure, asthma, and physical inactivity. Sex-stratified analyses reveal differences involving age, socioeconomic status, cancer, blood pressure, and lower body function.
  
  
  CONCLUSIONS
  Three-year weight changes in middle-aged African Americans were frequent and significantly associated with several risk factors.
