Regular physical exercise is not a widespread habit among the population. Early childhood in a crucial stage for acquiring this habit. The objective of this study was that of ascertaining the behavior of school-age children with regard to the degree of physical activity they do and to examine the factors involved.
An observational study was conducted by means of a survey based on a questionnaire which 6th and 8th grade students in a Basic Health Care District of Cordoba (N-585) filled out on their own. Questions were asked regarding the frequency of exercise, preferences and prospects for practicing sports, the children's physical shape and school physical education classes, in addition to other behavior comprising their lifestyles. A dual-variable (p .05) and a multiple-variable analysis was conducted employing logistic regression.
A total of 548 students filled out the survey (response rate = 97.8%). 79.3% (IC95% 75.7-82.6) were involved in extracurricular physical activities, 21.0% (IC95% 17.1-24.7%) being involved in intense physical exercise. 50.5% (IC95% 46.3-54.8) did not think that they were in good physical shape. The age, sex, type of residence, the involvement in sports on the part of their parents or a close friend and what they considered their degree of healthiness to be comprised the variables quite strongly linked to doing exercise (p .001).
The prevalence of physical exercise is high, although it progressively decreased with age, especially for girls. A major number of students considered themselves to be in unsatisfactory physical condition.
规律的体育锻炼在人群中并非普遍的习惯。幼儿期是养成这一习惯的关键阶段。本研究的目的是确定学龄儿童在体育活动程度方面的行为，并检查其中涉及的因素。
通过基于问卷的调查进行一项观察性研究，科尔多瓦一个基本医疗保健区的六年级和八年级学生（N = 585）自行填写问卷。除了包括他们生活方式的其他行为外，还询问了关于锻炼频率、运动偏好和前景、儿童的身体状况以及学校体育课的问题。采用逻辑回归进行双变量（p <.05）和多变量分析。
共有548名学生填写了调查问卷（回复率 = 97.8%）。79.3%（95%置信区间75.7 - 82.6）参与课外体育活动，21.0%（95%置信区间17.1 - 24.7%）参与剧烈体育锻炼。50.5%（95%置信区间46.3 - 54.8）认为自己身体状况不佳。年龄、性别、居住类型、父母或密友参与体育活动的情况以及他们认为自己的健康程度这些变量与进行锻炼有很强的关联（p <.001）。
体育锻炼的普及率较高，尽管其随年龄逐渐下降，尤其是女孩。大量学生认为自己的身体状况不理想。
