Active school transport (AST) is a recommended strategy to promote physical activity (PA) and prevent overweight (OW) in school-aged children. In many developing countries, such as Colombia, this association has not been well characterized.
To determine the association between AST and weight status in a representative sample of adolescents from Montería, Colombia.
Participants were 546 adolescents (278 boys) aged 11 to 18 years old from 14 randomly selected schools in Montería, Colombia in 2008. The PA module of the Global School Health Survey (GSHS-2007) was used to determine the prevalence of AST. To identify OW, participants were classified according to CDC 2000 criteria (BMI ≥85th percentile). Association between AST and OW was determined by binomial logistic regression.
Odds ratios adjusted for age, sex, location of school, compliance with PA, and screen time recommendations showed that adolescents who reported AST had a significantly lower likelihood to be OW compared with adolescents who reported nonactive transportation (OR = 0.5, 95% CI 0.3-0.8, P < .05).
These results support the importance of AST as a useful PA domain with potential implications for overweight prevention, in rapidly developing settings. Further epidemiologic and intervention studies addressing AST are needed in the region.
积极的学校交通出行（AST）是一项推荐策略，旨在促进学龄儿童的身体活动（PA）并预防超重（OW）。在许多发展中国家，如哥伦比亚，这种关联尚未得到充分描述。
确定哥伦比亚蒙特里亚具有代表性的青少年样本中AST与体重状况之间的关联。
2008年，从哥伦比亚蒙特里亚14所随机选取的学校中招募了546名11至18岁的青少年（278名男孩）。使用全球学校健康调查（GSHS - 2007）的身体活动模块来确定AST的患病率。为了识别超重，参与者根据美国疾病控制与预防中心（CDC）2000年标准（BMI≥第85百分位数）进行分类。通过二项式逻辑回归确定AST与超重之间的关联。
在对年龄、性别、学校位置、身体活动依从性和屏幕时间建议进行调整后，优势比显示，与报告非积极交通出行的青少年相比，报告AST的青少年超重的可能性显著降低（OR = 0.5，95% CI 0.3 - 0.8，P <.05）。
这些结果支持了AST作为一个有益的身体活动领域对于预防超重具有潜在意义的重要性，在快速发展的环境中。该地区需要进一步开展针对AST的流行病学和干预研究。
