To examine the associations between lifestyle factors and active commuting to school in Spanish adolescents.
Cross-sectional study. Lifestyle factors (overall/extracurricular physical activity, television viewing, reading as a hobby, sleep duration, breakfast/fruit intake, smoking and alcohol intake) as well as mode and duration of commuting to school were self-reported. Active commuters were defined as those adolescents who walked or cycled to school.
Secondary schools in Madrid, Spain.
Adolescents (n 2029) aged 13 to 17 years.
Similar percentages of adolescent boys (57·6 %) and girls (56·1 %) were classified as active commuters to school (P = 0·491). The analysis showed that only adequate sleep duration (OR = 1·35, 95 % CI 1·11, 1·66; P = 0·003) and breakfast consumption (OR = 0·66, 95 % CI 0·49, 0·87; P = 0·004) were independently associated with active commuting to school.
Only those behaviours that occur immediately before commuting to school (sleep and breakfast) are associated with active commuting in Spanish adolescents.
研究生活方式因素与西班牙青少年主动上学通勤之间的关联。
横断面研究。生活方式因素（总体/课外体育活动、看电视、阅读爱好、睡眠时间、早餐/水果摄入、吸烟和饮酒）以及上学通勤的方式和时间都是自我报告的。主动通勤者被定义为步行或骑自行车上学的青少年。
西班牙马德里的中学。
年龄在 13 至 17 岁的青少年（n=2029）。
相似比例的男青少年（57.6%）和女青少年（56.1%）被归类为主动上学通勤者（P=0.491）。分析表明，只有充足的睡眠时间（OR=1.35，95%CI 1.11，1.66；P=0.003）和早餐摄入（OR=0.66，95%CI 0.49，0.87；P=0.004）与主动上学通勤独立相关。
只有那些在上学通勤前立即发生的行为（睡眠和早餐）与西班牙青少年主动上学通勤相关。
