Abstract Aims Body roundness index (BRI) is an obesity‐related anthropometric index that combines waist circumference and height to better reflect body fat. This study aims to prospectively explore the relationship between BRI and the risk of heart failure (HF) based on a community‐based cohort. Methods and results A total of 140 362 individuals without tumour and HF at baseline were included from the Kailuan cohort study. Their demographic information, anthropometric parameters, and biochemical indexes were collected or measured. The participants were followed up until 31 December 2016 or death or diagnosed with HF, whichever came first. Cox proportional hazards model was used to calculate the hazard ratios (HRs) and 95% confidence intervals (CIs) for incident HF. Restricted cubic spline analysis was applied to further evaluate the possible non‐linear dose–response relationship between BRI and the risk of HF. After a median follow‐up period of 9.84 years, we identified 1990 HF events. The participants were grouped into four groups according to the quartiles of BRI (Q1: ≤2.93, Q2: 2.93–3.59, Q3: 3.59–4.38, and Q4: ≥4.38). After adjustment for potential confounders, compared with the group of participants in the lowest quartile of BRI, the adjusted HRs (95%CI) were 1.03 (95%CI: 0.87–1.22), 1.27 (95%CI: 1.07–1.49), and 1.50 (95%CI: 1.26–1.78) for subjects in the Q2, Q3, and Q4 groups, respectively. With each standard deviation (here is 1.10) of BRI increasing, the risk of HF increased by 18% (HR: 1.18, 95%CI: 1.12–1.24). Subgroup analysis indicated that the association between BRI and HF was more prominent in younger people (HR: 2.94, 95%CI: 1.80–4.80) than older (HR: 1.89, 95%CI: 1.57–2.27) (P for interaction < 0.001). A significant linear dose–response relationship between BRI and HF was also observed (P for non‐linearity = 0.730). Conclusions Our study suggests that higher BRI is associated with an increased risk of HF. If these findings can be replicated in other populations, future studies need to examine whether lowering the BRI may lower the risk of incident HF.
