Minnesota Heart Health Program (Table 3) | ‘No statistically significant treatment effects’; Author referenced two publications [31, 61] | ‘The residents of the intervention communities of the Minnesota Heart Health Study were somewhat more physically active (self-reported) at the end of the follow-up. The increased physical activity was apparently due to an increase in activities with a low intensity’ For a special school-based element of the study ‘Girls in the intervention communities reported significantly greater amounts of exercise than girls in control communities. Boys showed a similar tendency, but the difference […] was smaller.”Author referenced three publications [29–31] | ‘Some evidence that regular physical activity increased in experimental communities relative to control communities’ And ‘mass media approaches were most successful in heightening physical activity-related awareness and knowledge whereas setting-specific programs strategies that occurred over a period of time, such as those conducted in schools and worksites, were more cost- effective in increasing actual levels of physical activity participation’; Author referenced two publications [26, 31] | ‘Physical activity levels throughout most of the follow up period were significantly higher in the intervention community for females […] The class of 89 study could not distinguish between community and classroom effects but modest nature of the school-based activities suggests that the community based activities played an important role in the generally positive outcomes.’ Author referenced four publications [29–31, 34] | ‘Cohort data […] revealed an increase in physical activity in all of the communities,with the intervention communities slightly exceeding the comparison communities at the last follow-up survey’ and ’the exposure data suggest that the Minnesota Heart Health Program may not have added a great deal to the level of risk reduction activity that would have been expected without the program’; Author also reported an intervention effect for girls in the school based sub-study Author referenced one publication [31] | Different |
