The EAT-Lancet Commission has proposed a model diet to improve the health of human beings and that of the planet. Recently, we proposed the Planetary Health Diet Index (PHDI) to assess adherence of the population to this model diet. In this study, we aimed to evaluate adherence to the PHDI and obesity outcomes using baseline data from 14,515 participants in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). The dietary data were assessed using a 114-item FFQ. Body mass index (BMI) and waist circumference (WC) were both used continuously and categorized. Linear and multinomial regression models adjusted for potential confounding factors were performed to assess the relationship between adherence to PHDI and outcomes. An inverse association was observed between adherence to PHDI and obesity indicators. Individuals with high adherence to the PHDI had lower BMI (β-0.50 95% CI-0.73:-0.27) and WC (β-1.70 95% CI-2.28:-1.12) values. They were also 24% less likely to be overweight (OR 0.76 95% CI 0.67:0.85) or obese (OR 0.76 95% CI 0.65:0.88), and they were 14% and 27% less likely to have increased WC (OR 0.86 95% CI 0.75:0.98) or substantially increased WC (OR 0.73 95% CI 0.64:0.83) than those with lower adherence. Our results showed that higher adherence to the PHDI may decrease obesity indicators.
EAT 柳叶刀委员会提出了一种改善人类和地球健康的饮食模式。最近，我们提出了行星健康饮食指数（PHDI）来评估人群对这种饮食模式的遵守情况。在这项研究中，我们旨在使用巴西成人健康纵向研究（ELSA-Brasil）的 14515 名参与者的基线数据评估对 PHDI 的遵守情况和肥胖结果。使用 114 项 FFQ 评估饮食数据。身体质量指数（BMI）和腰围（WC）均连续分类，并进行了调整潜在混杂因素的线性和多项回归模型，以评估 PHDI 与结果之间的关系。PHDI 遵守程度与肥胖指标呈负相关。高 PHDI 遵守者的 BMI（β-0.50 95%CI-0.73：-0.27）和 WC（β-1.70 95%CI-2.28：-1.12）值较低。他们超重的可能性也降低了 24%（OR 0.76 95%CI 0.67：0.85）或肥胖（OR 0.76 95%CI 0.65：0.88），他们 WC 增加（OR 0.86 95%CI 0.75：0.98）或 WC 显著增加（OR 0.73 95%CI 0.64：0.83）的可能性也降低了 14%和 27%。我们的结果表明，较高的 PHDI 遵守程度可能会降低肥胖指标。
