Background : Foot and body odor have been found in some dermatologic diseases such as foot odor in pitted keratosis [PK]. The
studies about odors are limited, especially, their impacts on patients’ quality of life [QoL].
Objective : To demonstrate the effects of odor on patients’ QoL, focusing on foot odor and association between the severity of foot
odor and PK.
Materials and Methods: Seven hundred eighty-eight Thai naval rating cadets enrolled in the study. Odor was assessed by
questionnaires. The severity of foot odor was evaluated using visual analog scale [VAS] score by the participant’s self-determination.
QoL was assessed by Dermatology Life Quality Index [DLQI] questionnaire. Physical examination was performed by dermatologists.
The association among PK, DLQI total score, and odor were analyzed.
Results : Seven hundred twenty-nine participants (92.5%) completed the questionnaires and physical examination. Foot odor was
reported in 309 (42.4%), whereas body odor was found in 140 (19.2%). The mean DLQI total score signi(cid:976)icantly increased in the
participants who had foot or body odor; comparing with those without odor. The positive correlation between DLQI total score
and the severity of odor was demonstrated (r = 0.4, p-value <0.001). Foot odor signi(cid:976)icantly affected on patients’ QoL de(cid:976)ining as
DLQI score greater than 6 (p-value 0.04), comparing with those reporting no foot odor. Moreover, PK was described in 125 (17.1%)
cases in the present study. The median VAS score of foot odor was signi(cid:976)icantly different between the participants with and without
PK (p-value 0.002).
Conclusion : The present study demonstrated that odor had signi(cid:976)icant impact on patients’ QoL, using statistical analysis. Severity
of unpleasant foot odor was correlated with diagnosis of PK. Thus, physicians should pay attention to this problem and perform
a proper management.
