Urban-rural differences in the prevalence of female pattern hair loss among secondary school girls: A cross-sectional study.

AIM: Female pattern hair loss (FPHL) is a common condition that is influenced by many external and internal factors. We aimed to identify the prevalence of FPHL among secondary school girls and identify possible associated factors.

METHODS

FPHL among 3405 adolescent females was identified using detailed history, physical examination, and dermoscopy in this cross-sectional study.

RESULTS

Among the 3405 included students, 2430 (71.4%) had no FPHL and 975 (28.6%) were diagnosed with FPHL (p = 0.001). The mean age of girls with FPHL was 16.43 ± 1.10 and ranged between 15 and 18 years. Among those with FPHL, 427 (43.8%) attended urban schools while 548 (56.2%) attended rural schools. No significant differences regarding paternal and maternal education, family income, or parental degree of education were observed among those with FPHL and those without (p = 0.230; p = 0.063; p = 0.276, respectively).

CONCLUSION

FPHL had an overall prevalence of 28.6% among secondary school girls with a significant predominance in rural over urban areas and with a significantly associated family history. Irregular menses, history of thyroid disease, and hirsutism were significant predictors for FPHL.
