Adherence to the modified Planetary Health Diet among the working-age population in 185 countries from 1990 to 2018: a population-based study.
Background: Understanding global dietary patterns and their implications for human and planetary health has become increasingly critical. The Planetary Health Diet (PHD), introduced by the EAT-Lancet Commission in 2019, offers a framework to address nutrition-related diseases while mitigating environmental impacts.
Objectives: We aimed to analyze adherence to a modified PHD (mPHD) among working-age population (WAP) across 185 countries between 1990 and 2018.
Methods: We conducted a serial cross-sectional analysis using data from the Global Dietary Database (GDD) 2018. The modified Planetary Health Diet Index (mPHDI) score was constructed based on consumption of 12 food groups. Each component was scored from 0 to 10, generating a composite score ranging from 0 to 120. Distributive inequalities were assessed using the slope index of inequality and concentration index, which are 2 standard metrics of absolute and relative gradient inequality.
Results: Modest overall adherence to the mPHD recommendations [global mPHDI score: 75.2; 95% uncertainty interval (UI): 74.2, 76.3] was observed, with significant regional variations. Sub-Saharan Africa showed the highest adherence (84.5; 95% UI: 83.2, 85.5), whereas Latin America and the Caribbean showed the lowest (66.0; 95% UI: 64.5, 67.7). Excessive consumption of red/processed meat and added sugar was prevalent across various populations. Over the past 28 y, global improvement was minimal (+1.3; 95% UI: -0.1, 2.4), with concerning declines in South Asia (-4.0; 95% UI: -5.7, -2.2), despite substantial improvements in high-income countries (6.5; 95% UI: 4.0, 8.5). The slope index of inequality decreased from -15.48 (95% confidence interval [CI]: -19.2, -11.76) in 1990 to -8.49 (95% CI: -12.26, -4.72) in 2018.
Conclusions: Our findings reveal substantial global variations in mPHD adherence among WAP, with concerning trends in certain regions. These results provide crucial insights for developing targeted interventions that consider regional contexts while pursuing the dual objectives of promoting healthier diets and ensuring environmental sustainability.
期刊介绍：
American Journal of Clinical Nutrition is recognized as the most highly rated peer-reviewed, primary research journal in nutrition and dietetics.It focuses on publishing the latest research on various topics in nutrition, including but not limited to obesity, vitamins and minerals, nutrition and disease, and energy metabolism.
Purpose:
The purpose of AJCN is to:
Publish original research studies relevant to human and clinical nutrition.
Consider well-controlled clinical studies describing scientific mechanisms, efficacy, and safety of dietary interventions in the context of disease prevention or health benefits.
Encourage public health and epidemiologic studies relevant to human nutrition.
Promote innovative investigations of nutritional questions employing epigenetic, genomic, proteomic, and metabolomic approaches.
Include solicited editorials, book reviews, solicited or unsolicited review articles, invited controversy position papers, and letters to the Editor related to prior AJCN articles.
Peer Review Process:
All submitted material with scientific content undergoes peer review by the Editors or their designees before acceptance for publication.
