Keywords:
Lead Exposure, Male Workers, Unacceptable Health Risk, Chao Lay, Bulon Island, SatunAbstract
This predictive research aimed to study the level of health risk of lead exposure and the predicting factors for health risk of lead exposure among male workers in Bulon island, Satun province. The study was conducted from July to August, 2020. Samples were 130 male workers called Chao Lay, and calculated by G*power program. A cluster random sampling was applied. The research instrument was a questionnaire consisting of four parts: 1) demographic data, 2) job description, 3) frequency of health hazard exposure, and 4) health risk assessment. Content validity of the questionnaire was approved by three experts, yielding values ranged between 0.67-1.00. Reliability of questionnaire was tested using Conbach's alpha coefficient, yielding a value of .82. Data were analyzed using descriptive statistics, and stepwise multiple regression analysis. Results showed the following.
1. Most of health risk scores of lead exposure among male workers in Bulon island at Satun province were at an unacceptable risk level (50.77%) or a high risk level (19.23%).
2. It was found that 52.1 percent (R2adj= 0.521) of the variability of outcome variable could be explained by the combination of 2 variables with statistical significance (p<0.001): duration of occupation, and working time.
These research findings suggest that employer should pay more attention on duration of occupation and working time, in order to prevent lead exposure at an unacceptable rate.
