Abstract
Aim:
To investigate the health profile of a cohort of people receiving HD in Sri Lanka and to identify factors associated with interdialytic weight gain (IDWG).

Method:
Cross-sectional study of 166 adults receiving haemodialysis. A structured chart audit form collected demographic and HD treatment characteristics, and recent biochemical and haematological results. Odds ratios were calculated to identify independent risk factors for IDWG.

Results:
Mean age was 52 years (SD = 12.5), over half were male (60.2%, n = 100), and most were receiving four hours of HD once per week (87.3%, n = 145). Approximately half (51.8%, n = 86) had an IDWG > 2%. Being female (OR = 3.39; 95% CI, 1.51–7.61), increased comorbidities (OR = 1.50; 95% CI, 1.22 – 1.84) and having body mass index outside of the normal range (overweight/obese [OR = 8.49; 95% CI, 3.58–20.13] or underweight [OR = 4.61; 95% CI, 1.39–15.31) were independent risk factors for increased IDWG.

Conclusion:
Only modest alterations in potassium, phosphate, and fluid status were observed even though most patients were receiving four hours of HD once per week. Targeted, low-cost self-management interventions for ‘at risk’ groups could reduce the consequences of inadequate HD during times of war, climate, or financial challenges.
