Duration of Contact and Frequency of Contact Increased The Risk of Irritant Contact Dermatitis among Workers in Premix Division

Irritant contact dermatitis is inflammation of the skin due to direct contact with a substance on the surface of the skin. It is usually caused by substances such as solvents or other chemicals that can irritate the skin. Exposure can cause red spots and itching on the affected skin area. Irritant contact dermatitis occurs in 80% of all sufferers of contact dermatitis while allergic contact dermatitis only occurs about 10-20%. This study aims to determine the effect of duration of contact and frequency of contact on the incidence of irritant contact dermatitis among workers in premix division. This was an observational study with a cross sectional approach. The populations of this study were all workers in premix division with a total of 65 people who were taken with total sampling technique. Data collection method used herewas interview and physical examination by doctor. It was found that there was a relationship between duration of contact (p = 0.009) and frequency of contact (p = 0.000) and the incidence of irritant contact dermatitis. The results of multivariate analysis showed that the most influential variables on the incidence of irritant contact dermatitis were: duration of contact (p = 0.008), OR (Exp B) 8.257 and frequency of contact (p = 0.000), OR (Exp B) 56.519. The frequency of contact factor was the most dominant predictor. The provision of personal protective equipment in accordance with the potential hazards of chemicals such as neoprene gloves was intended to reduce direct contact with chemicals.
