Urinary Na:K (mmol/mmol) and prevalence of urinary Na:K ≤1.0 in Irish adults by age group and gender based on spot urine samples (n = 1121).* Corrected for gender-specific 24-h urine volume estimations derived from a study by Perry et al. (men: 1.97 L; women: 1.67 L). ** World Health Organisation (WHO) recommendation (molar Na:K ≤1.0) (WHO guidance on potassium at least 3510 mg per day, on sodium less than 2000 mg per day). *** Shown to exhibit lower CVD risk.
