Objective Whether or not combined lifestyle factors are associated with similar decreases in risks of incident hypertension and diabetes among individuals with and without chronic kidney disease (CKD) remains unclear.
Methods This population-based prospective cohort study included participants 40-74 years old who were free from heart disease, stroke, renal failure, hypertension, diabetes, and hypercholesterolemia at baseline (n =60,234). Healthy lifestyle scores (HLSs) were calculated by adding the total number of 5 healthy lifestyle factors (non-smoking, body mass index <25 kg/m2, regular exercise, healthy eating habits, and moderate or less alcohol consumption). Cox proportional hazards models were used to examine associations between the HLS and incident hypertension or type 2 diabetes and whether or not CKD modified these associations.
Results During a median of 4 years, there were 2,773 incident hypertension cases (30.1 cases per 1,000 person-years) and 263 incident diabetes cases (2.4 cases per 1,000 person-years). The risk of developing hypertension and diabetes decreased linearly as participants adhered to more HLS components. Compared with adhering to 0, 1, or 2 components, adherence to all 5 HLS components was associated with a nearly one-half reduction in the risk of hypertension (hazard ratio [HR] =0.52; 95% confidence interval [CI], 0.45-0.60) and diabetes (HR =0.51; 95% CI, 0.32-0.81) in fully adjusted models. CKD did not have a modifying effect on associations between the HLS and incident hypertension (Pinteraction =0.6) or diabetes (Pinteraction =0.3).
Conclusion Adherence to HLS components was associated with reduced risks of incident hypertension and diabetes, regardless of CKD status.
