The associations between physical activity in leisure time with special focus on jogging and the level of mental stress and life dissatisfaction were studied in 12 028 randomly selected men and women aged 20-79 years. The associations were similar in men and women; thus, results are given for pooled data. The odds ratios (ORs) are presented as adjusted for sex, age, body mass index, smoking, alcohol consumption, education and income. With increasing physical activity in leisure time, there was a decrease in high level of stress, between sedentary persons and joggers, OR=0.30 (95% confidence interval (CI) from 0.16 to 0.56). With increasing physical activity there was also a decrease in life dissatisfaction, between sedentary persons and joggers, OR=0.30 (95% CI from 0.18 to 0.52). Although there was a dose-response effect between physical activity and psychosocial well-being the most pronounced difference with regard to the level of stress and dissatisfaction was seen between the group with low and the group with moderate physical activity, e.g., 2-4 h of walking per week. In conclusion, we recommend that increased well-being should be a key argument in future campaigns for increased leisure-time physical activity.
