Association Between Hair Loss and Cardiometabolic Diseases in Chinese Adults: A Cross-Sectional Analysis in Tianning Cohort

This cross-sectional study of 5,020 Chinese adults from the Tianning cohort found that severe hair loss is associated with higher odds of hypertension, diabetes, and cardiometabolic multimorbidity (CMM), but not dyslipidemia. Specifically, individuals with severe hair loss had 48% higher odds of hypertension and 44% higher odds of diabetes. The associations were more pronounced in adults under 55 years and in women, suggesting shared hormonal and vascular mechanisms. Despite limitations such as potential residual confounding and the use of visual assessment scales, the study highlights the need for attention to cardiometabolic health in individuals with significant hair loss and suggests that hair loss may be an indicator of cardiometabolic health risks.
