ObjectiveTo explore the mediating effect of self-perceived burden on family support and health behavior in hemodialysis patients.

MethodsA total of 96 hemodialysis patients were selected.The general information questionnaire, self-perceived burden scale, family adaptability and cohesion evaluation scale Ⅱ, health promoting lifestyle profile scale -Ⅱ were distributed.Sequential regression test and classical ratio method were used to investigate the mediating effect of self-perceived burden on family health behavior and support function.

ResultsFamily support of hemodialysis patients had significant predictive value for health behavior(β=0.542, t=6.14, P < 0.01).Self-perceived burden score showed significant reverse predictive value for family support(β=-0.582, t=-7.21, P < 0.01).Taking health behavior as the dependent variable, the inclusion of self-perceived burden made the predictive value of family support to health behavior decline, but it was still significant(β=0.322, t=3.99, P < 0.01), and self-perceived burden predicted the health behavior of patients(β=-0.268, t=-4.05, P < 0.01).

ConclusionsSelf-perceived burden has a mediating effect on health behavior and family support.Intervening family support can improve self-perceived burden in patients.
