[Effects of different types of scaly scalp diseases on patients' quality of life]

This study investigated the disease spectrum in 209 patients with different types of scalp scaly cutaneous diseases. The quality of life of patients with the diseases were also analyzed. We found that seborrheic dermatitis (52.6%), dandruff (14.4%), eczema (17.7%) and psoriasis (15.3%) are common scalp scaly diseases. Eczema and psoriasis can be restricted to the scalp. The four diseases occur frequently in 20-40 years. Compared with patients with seborrheic dermatitis, those with dandruff were statistically different in terms of gender (P=0.004), occupation (P=0.010), drinking (P=0.007) and distressing factors (P=0.016). The average quality of life scores for scalp seborrheic dermatitis, dandruff, eczema and psoriasis were 3.00(1.00, 6.00),2.00(1.00, 5.25),4.00(1.00, 8.50)and 3.00(1.25, 6.75), respectively (P=0.42). The difference between the quality of the four diseases were not statistically significant. The diseases reduced patients' quality of life.
