The Mediterranean diet (MD) and other lifestyle characteristics have been associated with well-being, a broad multiparameter concept that includes individual's subjective assessment of their own well-being (SWB). Some studies have suggested that diet influences SWB, thus, this work aimed to add novel information on the association of MD and SWB in a sample of Portuguese adults. Data on sociodemographic, economic, lifestyle, diet, and SWB were collected through a self-filled online questionnaire. MD adherence was assessed by the Mediterranean Diet Adherence Screener (MEDAS) score ]. Results showed a moderate adherence to the MD in 490 Portuguese adults (mean MEDAS of 7.4 ± 2.1). A higher MD adherence was found to be significantly positively associated with women, employed individuals, a higher number of meals per day, and those with frequent contact with nature (-value < 0.0025, using Bonferroni adjustment). As a novelty, this study divided the participants into low SWB, medium SWB, and medium to high SWB profiles (3.9 ± 1.0; 6.2 ± 1.0; 8.2 ± 1.3, respectively; -value < 0.05), which reported significantly increasing MEDAS scores (6.5 ± 2.1; 7.3 ± 2.1; 7.8 ± 1.9; respectively, -value < 0.05).
地中海饮食（MD）和其他生活方式特征与幸福感有关，幸福感是一个广泛的多参数概念，包括个体对自身幸福感的主观评估。一些研究表明，饮食会影响幸福感，因此，本研究旨在为葡萄牙成年人样本中 MD 和幸福感之间的关联提供新的信息。通过在线自填问卷收集了社会人口统计学、经济、生活方式、饮食和幸福感方面的数据。采用地中海饮食依从性筛查器（MEDAS）评分评估 MD 依从性。结果显示，490 名葡萄牙成年人的 MD 依从性处于中等水平（平均 MEDAS 为 7.4 ± 2.1）。更高的 MD 依从性与女性、就业人员、每天用餐次数较多以及经常接触大自然的人呈显著正相关（-值<0.0025，采用 Bonferroni 调整）。本研究的新颖之处在于，将参与者分为低幸福感、中幸福感和中高幸福感三个组（3.9 ± 1.0；6.2 ± 1.0；8.2 ± 1.3，-值<0.05），报告显示 MEDAS 评分显著增加（6.5 ± 2.1；7.3 ± 2.1；7.8 ± 1.9，-值<0.05）。
