Abstract:
Objective To investigate the present situation of facial melanin of construction workers in Beijing area,to discuss the relative affecting factors,and to provide theoretical basis for theoretical research on photoaging and occupational protection for construction workers.Methods A total of 157 healthy male construction workers and 61 non-construction workers in Beijing were selected to conduct a questionnaire survey on their exposure to dust,sunlight,noise and high temperature in their working environment.The occurrence of melanin in their face skin was measured by melanin index (melanin index,MI) probe.T test,Spearman rank correlation analysis and multiple logistic regression were used for statistical analysis on two independent samples.Results The exposure of construction workers to dust,sunlight,noise and high temperature was significantly higher than that of non-construction workers (P ＜0.05);the melanin score of construction workers over 40 years old was significantly higher than that of non-construction workers (P ＜0.05) and positively correlated with age (P＜0.05);the melanin of construction workers was affected by age,sunlight and noise (P＜0.05).Conclusions The melanin level of the construction workers aged over 40 is significantly higher than that of the non-construction workers in Beijing.Age,sunlight and noise are the main factors affecting the melanin level.
