Which statement best describes predisposition factors in occupational skin conditions?

• A. They are always protective factors.
• B. They are unrelated to susceptibility.
• C. They are factors like age, sweating, and ATOPY that increase susceptibility.
• D. They refer to laboratory safety policies.

Answer: (C)

Predisposition factors are host-related characteristics that influence how susceptible someone is to occupational skin conditions. They describe inherent features of the person that affect their skin’s response to exposures, rather than something about the exposure itself. Examples like age, sweating, and atopy illustrate how biology can change the likelihood of developing dermatitis when workers are in contact with irritants or allergens. Age can alter skin barrier function and hydration; sweating can keep the skin moist and macerated, increasing irritation and permeation of substances; atopy reflects a genetic tendency toward heightened skin reactivity and allergic responses. These factors increase susceptibility, not provide protection, and they aren’t about safety policies or procedures.
