Incidence of brittle nails

Area of Science:

• Dermatology
• Epidemiology

Background:

• Brittle nails (onychoshizia) are a common condition with limited epidemiological data.
• Understanding the prevalence and demographics of brittle nails is crucial for public health awareness and resource allocation.

Purpose of the Study:

• To investigate the incidence and prevalence of brittle nails across diverse population groups.
• To analyze the gender and age-specific distribution of brittle nail occurrence.
• To assess treatment-seeking behaviors and perceived efficacy among affected individuals.

Main Methods:

• A cross-sectional study involving 1,584 individuals from five distinct groups: dental clinic outpatients, blood donors, elderly care residents, internal medicine clinic patients, and general practice patients.
• Data collection focused on the presence of brittle nails, demographic information (age, gender), and self-reported treatment history and beliefs.

Main Results:

• Approximately 20% of the total study population exhibited brittle nails.
• Women were significantly more affected (27%) than men (13%), with a higher male-to-female ratio in younger age groups.
• Among those with brittle nails, 44% had attempted treatments, but only 26% believed in their efficacy.

Conclusions:

• Brittle nails represent a prevalent condition, particularly in women, affecting a substantial portion of the general population.
• The low perceived efficacy of treatments suggests a need for further research into effective therapeutic interventions for brittle nails.
• The estimated market for brittle nail therapies indicates a significant unmet need and potential for improved management strategies.
