title: Prevalence of overweight and associated factors among Oklahomans.
abstract: BACKGROUND
  Obesity among adults in the, United States has been increasing for the last three decades. Overweight is associated with numerous health risks such as diabetes, atherosclerosis, hypertension, sedentary lifestyle, etc. It also throws a very heavy economic burden on society, estimated at $39.3 billion in 1986.
  
  
  OBJECTIVE
  To estimate the prevalence of obesity and its associated factors so that efforts to achieve the Healthy Oklahomans 2000 objectives may be brought into sharper focus.
  
  
  METHODS
  The study design is cross-sectional.
  
  
  METHODS
  The study is based on the data from the Behavioral Risk Factor Surveillance System (a three-stage cluster sample survey) for the years 1991 through 1994. Statistical analysis was done with SUDAAN software for complex survey.
  
  
  RESULTS
  More than 25% of Oklahomans are overweight. To reach the Year 2000 objectives, a reduction of 10% in overweight will have to be achieved in about three and one-half years. Prevalence of moderate obesity among women is higher than among men. Prevalence of severe obesity is higher among the black community than among other communities. However, prevalence of moderate obesity is the same among blacks and whites. Severe obesity is significantly higher among those with less than a high school education than among those with college education. The prevalence of moderate obesity among non-smokers is significantly higher than among smokers. Among the severely obese, hypertension is more than twice as prevalent as normal blood pressure. Among the moderately obese, high blood pressure is more than one and one-half times more prevalent than normal blood pressure. Obesity increases with age in a predictive manner; it drops after the age of 54. Moderate obesity is significantly higher among women who have had a hysterectomy than those who have not had a hysterectomy. Prevalence of severe obesity as well as moderate obesity is very much higher among diabetics than among non-diabetics. A large proportion of severely obese people are physically inactive. We did not find an association between consumption of fruits and vegetables as a part of normal diet and prevalence of obesity.
  
  
  CONCLUSIONS
  Strenuous and focused efforts need to be made among the vulnerable groups, in view of the short time left until year 2000, to reduce the prevalence of obesity to the level laid down in the Year 2000 objectives.
