Spouse marital adjustment and patient dietary adherence in chronic hemodialysis: A Comparison of Afro-Americans and Caucasians

Abstract

This study investigated racial differences in the relationship between spouse marital adjustment and dietary adherence of chronic hemodialysis patients. Sixty-eight adult patients and their spouse were subjects. Fifty-two percent of the patients were Caucasians while 48% were Afro-Americans. Spouses completed the Locke-Marital-Questionnaire (LMQ) and provided demographic data pertaining to their patient spouses. The patients' predialysis potassium levels (indices of food intake compliance) for the previous three months were matched with the respective questionnaires. Afro-American spouses, especially males, evidenced significantly lower marital satisfaction than Caucasian spouses. Afro-American female patients seemed to be most compliant as far as food intake wasconcemed. Although the spouse LMQ score was negatively correlated with interdialysis weight gain. Afro-Americans who generally scored lower on the LMQ did not differ from Caucasians in so far as their adherence to the dietary regimen was concerned. Implications for improving quality of life of hemodialysis couples in general, and Afro-Americans in particular are discussed.
