title: Primary Sarcopenia in Older People with Normal Nutrition.
abstract: OBJECTIVE
  The aim of this study was to investigate the presence of primary sarcopenia in older patients with normal nutrition and to assess the relationships between the primary sarcopenia with anthropometric measurements.
  
  
  METHODS
  In this prospective clinical cross-sectional study, six-hundred patients who applied to Polyclinic of Geriatrics between dates 2010 and 2011 have been evaluated. The 386 patients who were supposed to have potential secondary sarcopenia were excluded from the study. Age, gender, weight, height, BMI, calf and waist circumference, ongoing medications, additional diseases of the 214 patients included in the study have been surveyed. The sarcopenia criteria of EWSGOP have been applied.
  
  
  RESULTS
  Two hundred fourteen cases included in the study were composed of 148 female and 66 male subjects. Mean age was 71.8 ± 2.1 years. Sarcopenia was detected in 105 (49%) subjects while 109 (51%) were normal. Sixty-four female (61%) and 41 (39%) male subjects were sarcopenic. Normal group included 84 female (77%) and 25 male (23%) subjects. Incidence of sarcopenia was found higher in the female patients (p<0.001). No statistically significant difference was detected between sarcopenic and normal groups with respect to age, height, weight, calf circumference and evaluation tests. Waist circumference was higher in the sarcopenic group than the normal group (p=0.02). When both groups were analyzed for BMI; 53 (51%) of the 105 sarcopenic patients had BMI over 30 kg/m2 while 29 (27%) and 23 (22%) patients had BMI of 25-30 kg/m2 and below 25 kg/m2, respectively. Incidence of sarcopenia was significantly higher in the group with BMI over 30 kg/m2 when compared with the groups with BMI of 25-30 kg/m2 and below 25 kg/m2 (p=0.01).
  
  
  CONCLUSIONS
  Sarcopenia that makes older people physically dependent and decreases their quality of life that receive sufficient nutritional support and are also obese should be comprehensively investigated with respect to presence of sarcopenia.
