Occupational Hand Dermatitis amongst Cassava Processors in Rural Communities in Southwest Nigeria.

Area of Science:

• Occupational Health
• Dermatology
• Agricultural Science

Background:

• Hand dermatitis (HD) is a common inflammatory condition affecting the hands.
• Agricultural work, particularly in cassava processing, presents significant occupational health risks.
• Wet work and bare-hand exposure during cassava processing are identified as key factors contributing to HD.

Purpose of the Study:

• To investigate the prevalence and characteristics of hand dermatitis among cassava processors.
• To identify predisposing factors for hand dermatitis in this occupational group.
• To assess the impact of protective measures on HD incidence in rural Nigerian communities.

Main Methods:

• A cross-sectional study was conducted with 426 female cassava processors in Southwest Nigeria.
• The Nordic Occupational Skin Questionnaire (NOSQ-2002) was adapted to collect data on work-related skin diseases and environmental exposures.
• Data on participant demographics, symptoms, and glove usage were systematically gathered.

Main Results:

• The prevalence of hand dermatitis within 12 months was 13.4% (57 participants).
• Itching was the most reported symptom (10.3%), followed by pain (6.1%) and small bumps (4.9%).
• The palmar surface of the right hand was most frequently affected, and regular glove use was associated with no reported HD symptoms.

Conclusions:

• Cassava processors are at a significant risk for developing occupational hand dermatitis.
• Health education and the consistent use of protective gloves are crucial preventive strategies.
• Implementing protective measures can mitigate the incidence of hand dermatitis in this vulnerable workforce.
