The effect of social support and coping style on depression in patients with continuous ambulatory peritoneal dialysis in southern China.
OBJECTIVE
To explore the effect of social support and coping style on depression in patients on CAPD in Southern China.


METHODS
The patients undergoing CAPD therapy for more than 3 months were recruited from Jan 1 to May 31, 2009. The Beck Depression Inventory-II (BDI-II), Social Support Rating Scale, Medical Coping Modes Questionnaire, and Medical Outcomes Study Short Form (SF-36) were used to evaluate depression, social support, coping style, and quality of life (QoL), respectively.


RESULTS
Of the 191 recruited patients, 65 patients (34.0 %) suffered from depression, with a BDI-II score of 23.8 ± 8.4. The average score of QoL (44.9 ± 13.9 vs. 64.7 ± 14.2, p < 0.001), social support (37.9 ± 7.2 vs. 42.1 ± 7.3, p < 0.001), and "confrontation" coping style (17.2 ± 3.9 vs. 18.8 ± 3.8, p = 0.006) in depressed patients was significantly lower than those in non-depressed patients, respectively. While the depressed patients had significantly higher score of "acceptance-resignation" coping style (12.9 ± 2.5 vs. 10.4 ± 3.5, p < 0.001) compared with those of non-depressed patients. Univariate analysis showed that the BDI-II score was negatively associated with social support (r = -0.284, p < 0.001) and "confrontation" (r = -0.180, p = 0.013), but positively associated with "acceptance-resignation" (r = 0.482, p < 0.001). Logistic regression analysis revealed that age (OR = 0.971, p = 0.038), female sex (OR = 2.211, p = 0.039), diabetes mellitus (OR = 3.046, p = 0.015), long PD duration (OR = 1.021, p = 0.020), fatigue (OR = 2.500, p = 0.032), high Pittsburgh Sleep Quality Index (PSQI) score (OR = 1.143, p = 0.001), low social support (OR = 0.945, p = 0.046), and high "acceptance-resignation" (OR = 1.096, p = 0.020) were independently associated with depression.


CONCLUSIONS
There was a high prevalence of depression in CAPD patients. Age, female sex, diabetes mellitus, long PD duration, fatigue, sleep disturbance, low social support, and high "acceptance-resignation" coping style were independently associated with depression.
