Table_1_Relationships between different trends of the Mediterranean diet and cardiovascular disease-related risk factors in China: results from the CHNS study, 1997–2009.DOCX

ObjectivesThe present study aimed to explore the associations between Mediterranean diet trajectories (MDTs) and cardiovascular disease-related risk factors in Chinese adults.MethodsA total of 4,332 participants from the China Health and Nutrition Survey (CHNS) were included in this study. A group-based trajectory model (GBTM) was used to explore Mediterranean diet trajectories (MDTs). Linear regression analyses were conducted to assess the association between Mediterranean diet trajectories and cardiovascular disease-related risk factors. Stratified analyses by gender were also performed.ResultsThe following four groups were identified in the total population: Group 1 (Persistently low MDT, n = 292, 6.74%), Group 2 (Descent MDT, n = 537, 12.40%), Group 3 (Ascent MDT, n = 454, 10.48%), and Group 4 (Persistently high MDT, n = 3,049, 70.38%). Compared to the persistently low MDT (Group 1), both Group 2 and Group 4 were negatively related to low-density lipoprotein cholesterol (LDL-C) (Group 2: β = −0.23, 95% CI: −0.36 to −0.09, p = 0.001; Group 4: β = −0.25, 95% CI: −0.37 to −0.14, p

本研究旨在探讨地中海饮食轨迹（MDTs）与中国成年人心血管疾病相关风险因素之间的关联。研究方法：本研究纳入了中国健康与营养调查（CHNS）中的4,332名参与者。采用基于群体的轨迹模型（GBTM）来探究地中海饮食轨迹（MDTs）。通过线性回归分析评估了地中海饮食轨迹与心血管疾病相关风险因素之间的关联。此外，还按性别进行了分层分析。研究结果：在总体人群中识别出以下四个群体：第一组（持续低MDT，n=292，6.74%），第二组（MDT下降，n=537，12.40%），第三组（MDT上升，n=454，10.48%），以及第四组（持续高MDT，n=3,049，70.38%）。与持续低MDT（第一组）相比，第二组和第四组与低密度脂蛋白胆固醇（LDL-C）呈负相关（第二组：β=−0.23，95% CI：−0.36至−0.09，p=0.001；第四组：β=−0.25，95% CI：−0.37至−0.14，p
