摘 要:目的探讨中国lO~17岁中小学生耐力素质的影响因素。方法利用2010年中国学生体质与健康调研数据,选取资料完整的10~17岁中小学生为研究对象,共68458名,将耐力跑测试时间≤同年龄、同性别第25位百分数(P)时间值确定为耐力素质好,耐力跑测试时间≥同年龄、同性别P时间值确定为耐力素质差..比较不同耐力素质者,耐力跑时间的差异,同时,采用x2检验、logistic回归及多水平模型分析城乡、BMI、饮食、运动、锻炼意愿等因素对耐力素质的影响。结果68458名研究埘象中,耐力素质好者有34239名(50.0%).耐力素质差者有34219名(50.0%)。耐力素质好者的比例,乡村学生为53.8%(18285/33996),高于城市学生的46.3%(15954/34462)(X2=384.16,P〈0.01);肥胖学生为12.2%(448/3660),低于BMI正常I55.2%(28183/51028)]、超重[29.3%(2012/6874)]和消瘦的学生[52.1%(3596/6896)],差异有统计学意义(x。=3840.08,P〈0.01);每天吃早餐的学生为52.5%(25534/48679),高于从来不吃或每周吃l~2次早餐的学生[41.3%(3209/7768)]()(。=438.3l,P〈0.01);每天喝牛奶的学生为51.7%(11580/22379),高于从来不喝或有时喝牛奶的学生[49.2%(22659/46079)](0=39.84,P〈0.01);体育课充足的学生为55.3%(18961/34314),高于体育课不足的学生[44.7%(15278/34144)](x。=756.41,P〈0.01);每天体育锻炼lh及以上的学生占58.6%(9484/16195),高于锻炼lh以下学生[47.4%(24755/52263)](x。=619.82,P〈0.01);愿意参加长跑锻炼学生占60.1%(19287/32118),高于意愿为“一般”[45.4%(10569/23272)]和“不愿意”[33.5%(4383/13068)]学生(妒=2909.61,P〈0.01)。多水平分析显示,耐力素质差的风险,乡村学�Objective To explore the influencing factors on physical endurance among Chinese primary and middle school students aged 10 - 17. Methods Data was used from "2010 National Physical Fitness and Health Surveillance", from which 68 458 primary and middle school students with complete information were selected. Good physical endurance was defined as endurance running time ~〈 P2s of same gender and age, pool' physical endurance as i〉 P75 of same gender and age. Difference of endurance running time in different physical endurance groups was compared; chi-square test, logistic regression and muhiple level model were used to analyze influence of region, BMI, diet, exercise and exercise willingness on physical endurance. Results There were 34 293(50. 0% ) students of good physical endurance and 34 219 (50. 0% ) ones of poor physical endurance in 68 458 subjects. Percentage of good physical endurance was 53.8% ( 18 285/33 996) in rural students, higher than urban ones (46.3% ( 15 954/34 462) ) ( X2 = 384. 16, P 〈0. 01 ). Percentage of good physical endurance was 12.2% (448/3660) in obese students, lower than normal (55.2% (28 183/51 028) ), overweight (29.3% (2012/6874)) and emaciated ones (52. 1% (3596/6896)) (X2 =3840. 08, P 〈0. 01 ). Percentage of good physical endurance was 52.5% (25 534/48 679) in students having breakfast everyday, higher than ones never having breakfast or 1 - 2 times per week (41.3% ( 3209/7768 ) ) ( X2 ~ 438.31, P 〈 0. 01 ) . Percentage of good physical endurance was 51.7% ( 11 580/22 379 ) in students having milk everyday, slightly higher than ones never or sometimes having milk (49.2% (22 659/46 079) ) ( X2 = 39.84, P 〈0. 01 ). Percentage of good physical endurance was 55.3% ( 18 961/34 314) in students with adequate physical education class, higher than ones with inadequate class (44. 7% ( 15 278/34 144) ) ( X2 = 756. 41, P 〈 0. 01 ).
