title: Relationship between cigarette smoking and one leg with eyes closed balance in Japanese men.
abstract: OBJECTIVE
  To investigate the link between cigarette smoking and one leg with eyes closed balance in Japanese men.
  
  
  METHODS
  We used data from 4224 Japanese men, aged 43.3 ± 13.9 years, in this cross-sectional study. Balance, such as one leg with eyes closed balance was measured. In addition, cigarette smoking habits were obtained by well-trained medical staff. The effect of cigarette smoking on one leg with eye closed balance was evaluated.
  
  
  RESULTS
  A total of 1613 men (38.2 %) had smoking habit and 1471 men (34.8 %) regularly exercised. Age-related changes in one leg with eyes closed balance were noted. One leg with eyes closed balance in subjects with cigarette smoking (30.9 ± 31.8 s) was significantly lower than those in subjects without cigarette smoking (32.4 ± 33.5 s) even after adjusting for confounding factors i.e. age, body weight and exercise habits.
  
  
  CONCLUSIONS
  Cigarette smoking might be associated with one leg with eyes closed balance in Japanese men.
