title: High Prevalence of Malnutrition among the Above Thirteen with Primary Pyomyositis in Northern Uganda.
abstract: OBJECTIVE
  To determine the prevalence of malnutrition and its association with primary pyomyositis among patients and controls who were age and sex matched.
  
  
  METHODS
  A case-control study was conducted at Gulu Regional, Lacor, Kalongo, Kitgum and St. Joseph's Hospitals in Northern Uganda.
  Study was conducted from September 2011 to November 2013.
  
  
  METHODS
  Primary pyomyositis patients were consecutively recruited to these Hospitals and were age and sex-matched with controls selected during the same period. History, physical examinations, Body Mass Index (BMI), blood samples for haematology, biochemistry, clinical chemistry and muscle biopsy for histology were obtained. Those that did not meet the inclusion criteria were excluded. The study was approved by the Ethics and Review Committee of Gulu University Medical School.
  
  
  RESULTS
  During the study period, 63 patients and 63 controls were recruited; 29 females and 34 males. Among primary pyomyositis patients, 59 (93.7%) had malnutrition while there were 2 in the control group, giving a prevalence of 3.2%.The matched analysis produced an aOR of 449.875 with a 95% CI (79.382, 2549.540; p<0.001) for malnutrition. Among the cases, 16 (25.4%) fulfilled the Clinical Case Definition (CCD) for AIDS, compared to 2 (3.2%) among the controls. The adjusted Odds ratio for the difference in fulfilling the CCD for AIDS between cases and controls was statistically significant aOR of 10.383 with a 95% CI (2.275, 47.397; p<0.001).
  
  
  CONCLUSIONS
  Primary pyomyositis is a common health problem in Northern Uganda. It is evident that malnutrition is the most common risk factor in Primary pyomyositis especially among the above thirteen year olds in Northern Uganda.
