Abstract：
UNASSIGNED: The aim of this study was to analyse whether the association between adherence to the Mediterranean diet and health-related quality of life (HRQoL) is mediated by physical fitness components (i.e., cardiorespiratory fitness, lower-limb strength, upper-limb strength and motor competence) in adolescents.
UNASSIGNED: This is a cross-sectional study including mediation analyses. This study involved 181 adolescents (86 girls) aged 15.8 ± 0.3 years recruited from secondary schools and sport clubs located in Castellon (Spain). Adherence to the Mediterranean diet was evaluated using the KIDMED questionnaire. HRQoL was assessed with the KIDSCREEN-10 questionnaire. Cardiorespiratory fitness was assessed using the 20-m shuttle run test. Lower-limb strength was assessed through the standing broad jump test. Upper-limb strength was evaluated using a handgrip dynamometer. Motor competence was assessed using the 4 × 10 m shuttle run test. Mediation analyses were performed for each physical fitness component in order to assess its mediating effect on the association between adherence to the Mediterranean diet and HRQoL. Indirect effects (IE) with confidence intervals (CI) not including zero were interpreted as statistically significant.
UNASSIGNED: Cardiorespiratory fitness and lower-limb strength had a mediating effect on the positive association between adherence to the Mediterranean diet and HRQoL (IE = 0.11, 95 % CI = 0.01; 0.27 and IE = 0.07, 95 % CI = 0.01; 0.19). Upper-limb strength and motor competence did not act as mediators in the association between adherence to the Mediterranean diet and HRQoL (IE = 0.00, 95 % CI = -0.04; 0.07 and IE = 0.01, 95 % CI = -0.03; 0.07, respectively).
UNASSIGNED: Our findings showed that the positive association of adherence to the Mediterranean diet on adolescents\' HRQoL was mediated by physical fitness. Educational and public health strategies aiming to improve Spanish adolescents\' HRQoL should focus on diet and physical fitness.

摘要：
■这项研究的目的是分析坚持地中海饮食与健康相关生活质量（HRQoL）之间的关联是否由身体健康成分介导（即，心肺健康，下肢力量,青少年的上肢力量和运动能力）。
■这是一项横断面研究，包括调解分析。这项研究涉及181名年龄在15.8±0.3岁的青少年（86名女孩），他们从位于Castellon（西班牙）的中学和体育俱乐部招募。使用KIDMED问卷评估对地中海饮食的依从性。使用KIDSCREEN-10问卷评估HRQoL。使用20米穿梭试验评估心肺适应性。通过站立跳远测试评估下肢力量。使用手柄测力计评估上肢力量。使用4×10m穿梭运行测试评估了运动能力。对每个身体健康成分进行了中介分析，以评估其对坚持地中海饮食与HRQoL之间关联的中介作用。置信区间（CI）不包括零的间接效应（IE）被解释为具有统计学意义。
■心肺健康和下肢力量对坚持地中海饮食和HRQoL之间的正相关具有中介作用（IE=0.11，95％CI=0.01;0.27和IE=0.07，95％CI=0.01;0.19）。在坚持地中海饮食与HRQoL之间的关系中，上肢力量和运动能力并不充当媒介（IE=0.00，95％CI=-0.04；0.07和IE=0.01，95％CI=-0.03；0.07，分别）。
■我们的研究结果表明，坚持地中海饮食对青少年HRQoL的正相关是由身体素质介导的。旨在改善西班牙青少年HRQoL的教育和公共卫生策略应侧重于饮食和身体健康。
