title: [Impact factors on physical activity level among the urban junior high school personnel in Hangzhou].
abstract: OBJECTIVE
  To explore the level of physical activities (PA) and related influencing factors among junior high school personnel in Hangzhou.
  
  
  METHODS
  In a cross sectional study, a self administered questionnaire was used to assess the levels of PA. Kruskal-Wallis H test and ordinal regression were applied to analyze the related factors.
  
  
  RESULTS
  Among the 1 497 school personnel included in this study, prevalence rates on the low, moderate and high levels of PA were 40.8%, 40.6% and 18.6%, respectively. Data from the multinomial logistic regression analysis indicated that:when comparing with the low level, people aged ≥ 45 (OR = 1.576, 95% CI:1.128-2.201) or those having minor perceived stress (OR = 1.490, 95% CI:1.141-1.946) more likely to fall into the moderate level. However, factors as higher awareness scores on the benefit of PA (OR = 1.070, 95%CI:1.002-1.143), being male (OR = 3.088, 95%CI:2.162-4.409), always or very often taking PA together with colleagues (OR = 2.903, 95%CI:1.587-5.312), taking PA once in a while together with colleagues (OR = 1.900, 95%CI:1.160-3.110) or having space to walk around home (OR = 1.657, 95% CI:1.022-2.688) would increase the likelihood of having high PA level. However, factors as marital status, socioeconomic status, years of working at school, BMI, level of having received education and positive impact from colleagues etc. did not seem to have significantly related to the PA level.
  
  
  CONCLUSIONS
  Gender, age, stress from work and supportive environment should be taken into account while planning on promoting the PA level among junior high school personnel in Hangzhou.
