Adherence to the Mediterranean diet (MD) has previously been related to better quality of life in the general population. Further, children and adolescents have obtained better health outcomes when they have shown high adherence to the MD in recent studies. Nevertheless, the association between the adherence to this type of diet and subjective happiness have not been previously analysed in this population. The main aim of the present study was to evaluate the relationship between MD adherence, health-related quality of life (HRQOL) and subjective happiness in a sample of 527 Spanish adolescents. Results obtained show positive associations of MD adherence with higher levels of subjective happiness and better HRQOL. Moreover, mediation analyses showed a full mediation effect of some components of HRQOL, namely, emotional well-being, mood and emotions, financial resources and social acceptance, in the association between MD adherence and subjective happiness. This study advances our understanding of the association of MD and levels of happiness in the general population, specifically in adolescents, through the positive effects of specific components of HRQOL. Future studies should evaluate other variables that could influence or also mediate this relationship, evaluating specific groups of adolescents, such as clinical samples.
先前有研究表明，坚持地中海饮食（Mediterranean diet，MD）与普通人群的生活质量改善有关。此外，最近的研究表明，儿童和青少年如果高度遵循 MD，他们的健康状况会更好。然而，这种饮食方式与主观幸福感之间的关联在该人群中尚未得到先前的分析。本研究的主要目的是评估在 527 名西班牙青少年样本中，MD 依从性、与健康相关的生活质量（health-related quality of life，HRQOL）和主观幸福感之间的关系。研究结果表明，MD 依从性与更高的主观幸福感和更好的 HRQOL 呈正相关。此外，中介分析表明，HRQOL 的某些成分，即情绪幸福感、情绪和情感、经济资源和社会接纳，在 MD 依从性和主观幸福感之间的关联中具有完全中介作用。本研究通过 HRQOL 的特定成分的积极影响，增进了我们对 MD 和普通人群幸福感水平之间关联的理解，特别是在青少年中。未来的研究应该评估可能影响或也介导这种关系的其他变量，并评估特定的青少年群体，如临床样本。
