To examine eating habits and energy and nutrient intake among adolescents participating in weight-related and power team sports and non-sport-involved adolescents.
Data were drawn from Project EAT (Eating Among Teens), which was conducted with 4,746 adolescents from 31 middle and high schools in the Minneapolis/St Paul metropolitan area.
Urban secondary schools.
Adolescents reporting participation in a weight-related sport, a power team sport, or no consistent participation in a sport.
Meal and snack frequency, mean energy and nutrient intake, and mean physical activity.
Analyses were conducted by sex across the three groups. General linear models were used to compare mean energy and nutrient intake, composite nutrient adequacy, and mean physical activity across the three groups. Percentages of youth meeting nutrient recommendations were compared across the three groups using chi(2) tests.
For both males and females, youth involved in weight-related sports ate breakfast more frequently than non-sport-involved peers (females: 3.6 and 3.2 times per week, respectively, P<0.01; males: 4.7 and 3.7 times per week, respectively, P<0.01). Weight-related and power team sport-involved youth also had higher mean protein, calcium, iron, and zinc intakes than non-sport-involved peers. However, adolescent females had low calcium intake, regardless of sports involvement (weight-related sports 1,091 mg/day, power team sports 1,070 mg/day, and non-sport-involved 1,028 mg/day, P<0.05).
Sport-involved adolescents have better eating habits and nutrient intake than their non-sport-involved peers. However, they are still in need of nutrition interventions, particularly around calcium intake.
研究参与与体重相关运动和力量团队运动的青少年以及不参与运动的青少年的饮食习惯、能量和营养摄入情况。
数据来自“青少年饮食”(EAT)项目,该项目对明尼阿波利斯/圣保罗大都市地区31所中学的4746名青少年进行了调查。
城市中学。
报告参与与体重相关运动、力量团队运动或未持续参与任何运动的青少年。
进餐和吃零食的频率、平均能量和营养摄入量以及平均身体活动量。
按性别对三组进行分析。使用一般线性模型比较三组的平均能量和营养摄入量、综合营养充足率以及平均身体活动量。使用卡方检验比较三组中达到营养建议标准的青少年百分比。
对于男性和女性青少年,参与与体重相关运动的青少年吃早餐的频率均高于不参与运动的同龄人(女性:分别为每周3.6次和3.2次,P<0.01;男性:分别为每周4.7次和3.7次,P<0.01)。参与与体重相关运动和力量团队运动的青少年的平均蛋白质、钙、铁和锌摄入量也高于不参与运动的同龄人。然而,无论是否参与运动,青春期女性的钙摄入量都较低(参与与体重相关运动的女性为1091毫克/天,参与力量团队运动的女性为1070毫克/天,不参与运动的女性为1028毫克/天,P<0.05)。
参与运动的青少年比不参与运动的同龄人有更好的饮食习惯和营养摄入。然而,他们仍需要营养干预,特别是在钙摄入方面。
