A new study suggests seasonal changes in salt intake affect blood pressure differently in men and women with chronic kidney disease (CKD). Researchers tracked 168 CKD patients over a year, analyzing urine samples and clinical data. While blood pressure and salt intake were generally higher in winter, a strong link between higher salt intake and increased systolic blood pressure was observed in men, particularly during the summer.
Female participants showed fewer seasonal changes. The findings highlight potential sex-specific implications for managing diet and hypertension in CKD patients, suggesting targeted interventions during summer for men may be beneficial. Further research is needed to understand the underlying mechanisms.
