研究问题
Over recent decades, nutritional epidemiology has shifted from individual nutrients towards overall dietary patterns.1 Evidence from cohort and intervention studies consistently links healthier dietary patterns to lower risks of major chronic diseases and healthier ageing outcomes.2–6 At the same time, population ageing and rapid nutrition transitions are reshaping disease burdens worldwide, while food environments…
方法
[Covariates and outcomes] To account for major socioeconomic and ecological differences between countries, we included urbanisation rate, population density, per capita health expenditure, population-weighted exposure to ambient fine particulate matter with an aerodynamic diameter of 2.5 μm or less (PM2.5), the Socio-demographic Index (SDI), annual minimum and maximum temperature, precipitation, and altitude.；Analyses of dietary adherence included all 185 countries, whereas outcome models included 164 countries with sufficient outcome and covariate data.；To examine whether associations between dietary adherence and HALE varied across geography and calendar time, we fitted geographically and temporally weighted regression (GTWR) models.34 35 GTWR gives greater weight to observations that are closer in space and time and allows regression coefficients to vary across locations.；They included DMI, sex, and the prespecified socioeconomic and ecological covariates.
核心结论
In South America, Brazil was consistently classified in low–low clusters for AHEI, with a median local Moran’s I of 0.92 (95% UI 0.56–1.17).；In East Asia, China formed a prominent hotspot for WCRF and hPDI, remaining in high–high clusters in up to 100% of observed years. ‖ 结论：These component probabilities are then combined using an aggregation rule that increases the influence of marked shortfalls on the overall score.
局限
Between-country heterogeneity was greatest in midlife.；The contrast between sub-Saharan Africa and East Asia illustrates why dietary adherence and its association with HALE should be considered separately.；Existing examples, including the sugar-sweetened beverage levy in South Africa and sodium-reduction strategies in China, show that component-specific dietary policies can be implemented at population scale.43–46 DMI could provide a common framework for identifying dietary components that may warrant greater attention in different populations.

本文属人体研究证据，但需注意：观察性或小样本干预的结论不等于已证实临床获益；效应量与长期安全性仍需更大规模、更长随访的试验验证。
