Our aim was to analyze multilevel correlates of cardiorespiratory fitness (CRF) according to sex, nutritional status and maturity status among adolescents.
Cross-sectional study conducted in public schools.
This was a cross-sectional study on 1,209 adolescents aged between 10 and 17 years. CRF was estimated from the 20-meter shuttle run test. Anthropometric data on body mass index and waist circumference were obtained. Somatic maturation was assessed from the peak height velocity. Questionnaires were used to evaluate socioeconomic variables (family income, parents' education level and number of siblings) and behavioral variables (physical activity, screen time and alcohol and tobacco consumption) among the parents and adolescents.
Boys, adolescents with normal weight and on-time maturers presented greater CRF (P < 0.05). Concerning socioeconomic correlates, girls (tobacco smoking, alcohol consumption, physical activity and screen time), adolescents with normal weight (alcohol consumption, physical activity and screen time), and on-time maturers (alcohol consumption, physical activity during childhood and habitual physical activity) demonstrated higher numbers of behavioral correlates with CRF. Normal-weight adolescents presented a higher number of biological correlates (chronological age, age at peak height velocity and waist circumference).
Different correlates were observed according to sex, nutritional status and somatic maturation status. However, habitual physical activity, waist circumference and chronological age seemed to be the strongest factors associated with cardiorespiratory fitness among adolescents.
我们的目的是分析青少年中根据性别、营养状况和成熟状态的心肺适能（CRF）的多层次相关因素。
在公立学校进行的横断面研究。
这是一项针对1209名年龄在10至17岁之间青少年的横断面研究。通过20米往返跑测试估算CRF。获取了体重指数和腰围的人体测量数据。根据身高增长高峰速度评估身体成熟度。使用问卷评估父母和青少年的社会经济变量（家庭收入、父母教育水平和兄弟姐妹数量）以及行为变量（身体活动、屏幕时间以及酒精和烟草消费）。
男孩、体重正常的青少年和按时成熟者的CRF更高（P<0.05）。关于社会经济相关因素，女孩（吸烟、饮酒、身体活动和屏幕时间）、体重正常的青少年（饮酒、身体活动和屏幕时间）以及按时成熟者（饮酒、儿童期身体活动和习惯性身体活动）与CRF的行为相关因素数量更多。体重正常的青少年呈现出更多的生物学相关因素（实足年龄、身高增长高峰速度时的年龄和腰围）。
根据性别、营养状况和身体成熟状态观察到不同的相关因素。然而，习惯性身体活动、腰围和实足年龄似乎是青少年心肺适能最强的相关因素。
