The heterogeneity in reported effects was reduced in higher quality studies , when physical activity was self-directed with some professional guidance and when there was on-going professional support .
Our review suggests that physical activity interventions have a moderate effect on self reported physical activity and cardio-respiratory fitness , but not on achieving a predetermined level of physical activity .
Due to the clinical and statistical heterogeneity of the studies , only limited conclusions can be drawn about the effectiveness of individual components of the interventions .
BACKGROUND Little is known about the effectiveness of strategies to enable people to achieve an increase in their physical activity .
OBJECTIVES To assess the effects of interventions for promoting physical activity in adults aged 16 years and older , not living in an institution .
A systematic review of physical activity promotion in primary care office settings.
OBJECTIVE To assess the efficacy of physical activity promotion in primary care office setting s. DESIGN Systematic review of clinical trials in which the efficacy of physical activity promotion was investigated in a primary care office setting with at least one month of follow up . SUBJECTS A total of 13,981 adults , aged 17 - 85 + , were included from 203 practice s in eight trials assessing physical activity promotion in primary care office setting s. MAIN OUTCOME MEASURES Odds ratios and 95 % confidence intervals were calculated comparing the number of participants who increased their physical activity or were active at follow up in the intervention group with a control group for each study . RESULTS Five of eight trials where positive with statistically significant results ( range 0.91 - 6.56 ) , but significant biases or limited clinical relevance of the outcomes were found in all trials . Short term trials of less than one year ( four of four were positive ) , single-risk-factor trials ( three of three were positive ) , r and omised clinical trials ( two of three were positive ) , and those assessing moderate levels of physical activity ( three of four were positive ) were most likely to find benefit . Only one of four trials lasting longer than a year were positive . CONCLUSION There is limited evidence from well design ed trials that office based physical activity promotion in primary care setting s is efficacious in promoting changes in physical activity that could conceivably have lasting clinical benefits
