title: Relationship of weight status with mental and physical health in female fibromyalgia patients.
abstract: OBJECTIVE
  To analyze the association of weight status with anxiety, depression, quality of life and physical fitness in fibromyalgia (FM) patients.
  
  
  METHODS
  The sample comprised 175 Spanish female FM patients (51.2 ± 7 years). We assessed quality of life by means of the Short-Form-36 Health Survey (SF36) and anxiety and depression by means of the Hospital Anxiety and Depression Scale (HADS). We used standardized fieldbased fitness tests to assess cardiorespiratory fitness, muscular strength, flexibility, agility, and static and dynamic balance. BMI was calculated and categorized using the international criteria.
  
  
  RESULTS
  33% of the sample was normal-weight, 35% overweight and 33% obese. HADS-anxiety and HADS-depression levels increased across the weight status categories. Obese patients had higher anxiety and depression levels compared to normal-weight patients (p < 0.05) whereas no differences were observed between overweight and obese patients. Physical functioning, bodily pain, general health (all p < 0.01) and mental health (p < 0.05) subscales from the SF36 were worse across the weight status categories. Likewise, levels of cardiorespiratory fitness, dynamic balance/motor agility (both p < 0.05) and upper-body flexibility (p < 0.001) decreased as the weight status increased. Pairwise comparisons showed significant differences mainly between the normal-weight versus obese groups.
  
  
  CONCLUSIONS
  Obese female FM patients displayed higher levels of anxiety and depression and worse quality of life, cardiorespiratory fitness, dynamic balance/motor agility and upper-body flexibility than their normal-weight peers.
