چکیده مقاله
Study of 100 WWTP operators in Tehran examined links between blood group and productivity indicators fatigue, concentration, performance O 30% and A 25% were most common; B 4% least O− and O reported lower fatigue and higher concentration/performance; B and AB− showed opposite patterns ANOVA showed significant group differences p < 0 05 Tukey tests highlighted O− vs B fatigue, concentration and O vs AB− performance Regression controlling for age, gender, education, and experience identified O− as a predictor of lower fatigue β = −0 28, p = 0 003 and higher concentration β = 0 31, p = 0 001 ; O−/O predicted better performance β = 0 26, p = 0 005 Education, shift type, and role also mattered: diploma/bachelor > master’s; rotating shifts > fixed; supervisors excelled despite more fatigue Fatigue correlated negatively with concentration r = −0 61 and performance r = −0 52 ; concentration correlated positively with performance r = 0 49 Biological and occupational factors jointly shape productivity
