Alarmingly high prevalence of obesity in haemophilia in the state of Mississippi.

The state of Mississippi has consistently been ranked as the state with most number of obese people in the United States with prevalence rates of >30%. Our aims in this study were to estimate the prevalence of overweight and obesity in children and adults diagnosed with haemophilia in Mississippi, and to assess whether race/ethnicity and the severity of haemophilia are important risk factors. A retrospective chart review was performed for all haemophilic patients seen at the Mississippi Hemophilia Treatment Center. Patients were classified into two major age groups: age 2-19.9 years and > or =20 years. Body mass index (BMI) was calculated from the height and weight in kg m(-2) from the last clinic visit. Out of a total of 132 haemophilic patients, 61% were white and 37% were African American. Overall, 51% of the haemophilic patients were either obese or overweight. The prevalence of obesity in the adult (> or =20 years old) haemophilic patients was 36% and an additional 32% were overweight. A significantly greater proportion of patients >20 years old were overweight or obese as compared with the patients in the 2-19.9 year age range (P < 0.002). However, race/ethnicity and severity of haemophilia were not significant risk factors for overweight and obesity. There is a very high prevalence of obesity in the Mississippi haemophilic population, especially in adults. Particular attention at clinic visits should be paid to the BMI in order to identify patients that are overweight or obese to allow for early and appropriate intervention.
