^aLogistic regression models were adjusted for age, gender, race, education, smoking, family history of PD, and residential and occupational pesticide exposures.

^bCompetitive Sports = sum of sport MET value*year of participation (MET-year); tertiles – age periods specific .

Occupational Activity = sum of job MET value*year of participation (MET-year); quartiles – age periods specific.

^cLinear trend was tested using the midpoint of each exposure category as a continuous variable in the regression model.
