Abstract
Objectives To determine the mediating effects of depression on health-related quality of life and fatigue in individuals with multiple sclerosis (MS).

Design A cross-sectional study.

Setting Tertiary urban hospital.

Participants One hundred and eight patients (54% women) with MS participated in this study.

Outcome measures Demographic and clinical data (weight, height, medication and neurological impairment), fatigue (Fatigue Impact Scale), depression (Beck Depression Inventory-II) and health-related quality of life (Short-Form Health Survey 36) were collected.

Results Fatigue was significantly associated with bodily pain, physical function, mental health and depression. Depression was associated with bodily pain and mental health. The path analysis found direct effects from physical function, bodily pain and depression to fatigue (all, P<0.01). The path model analysis revealed that depression exerted a mediator effect from bodily pain to fatigue (B=−0.04, P<0.01), and from mental health to fatigue (B=−0.16, P<0.01). The amount of fatigue explained by all predictors in the path model was 37%.

Conclusions This study found that depression mediates the relationship between some health-related quality of life domains and fatigue in people with MS. Future longitudinal studies focusing on proper management of depressive symptoms in individuals with MS will help determine the clinical implications of these findings.
take control of your own health
pursue optimal self care at least as actively as a diagnosis
ask for referrals to preventive health care specialists eg dietitians
don't let suboptimal self care muddy any underlying diagnostic picture!
