Integrating epidemiologic modeling and explainable machine learning to evaluate body roundness index for WHO-defined high cardiovascular risk: evidence from the ChinaHEART-Luohe screening cohort (opens in new tab)

BackgroundEfficient identification of individuals at high cardiovascular disease (CVD) risk is essential for prevention in middle-aged and older adults. The body roundness index (BRI), derived from waist circumference and height, may capture body-shape-related risk beyond conventional measures. We examined the association of BRI with World Health Organization (WHO)-defined CVD high-risk status in a community-based screening population.MethodsThis cross-sectional study used baseline data from ...
