PA: Physical Activity; C: Control condition; Ibasic: Basic tailored intervention condition; Iplus: Intervention plus including environmental information; Ibasic vs C: effect basic tailored intervention compared with control condition; Iplus vs C: effect intervention plus compared with control condition; Iplus vs Ibasic: effect intervention pluscompared with basic tailored intervention; Perc. Environment: number of perceived physical activity possibilities in direct environment [0-8]; SD: Standard deviation; SE: Standard Error. Regression models were adjusted for age, gender, educational status, occupational status, BMI, baseline levels of outcome, and within- district clustering effects.
