PURPOSE: Evaluate the impact of different interventions at workplace to increase the physical activity (PA) and to reduce cardiovascular risk in middle-aged women. DESIGN: RCT with 4 arms. Realized between, February (2010 - 2012) and data analyzed between March and July (2012). SETTING/PARTICIPANTS: 195 women aged 40 to 50 years that did not perform PA in leisure time were randomly assigned to one of 4 interventions. INTERVENTION: Control group (GI) a brief medical orientation (n = 47); Pedometer-Based Individual Counseling (GII) (n = 53); Pedometer-based Group Counseling (GIII) (n = 48); Aerobic Training (GIV, n = 47). MAIN OUTCOME MEASURES: Median change for total steps number (primary outcome), median change for moderate (>110 steps/min) steps number, body mass and waist circumference (secondary outcomes) after 3 or 6 months of intervention. RESULTS: Only the groups using pedometers (GII and GIII) significantly increased total steps number after 3 months (P<0.05); however the increase in total steps observed in GIII was higher than in GII (p<0.05). GIII also increased the number of moderate steps number. Moreover, after 6 months, no difference was observed among groups. Despite that, women did not modify the body mass that was reduced only in those of the AT group either after 3 and 6 months (-0.7 Kg) (P<0.05). Finally, it was found that interventions with the greatest number of sessions (GIII and GIV) had higher dropout (respectively, 30% and 45%) of participants when compared to GI and GII (respectively, 2% and 4%) (p <0.05).CONCLUSIONS: A pedometer-based intervention with counseling groups at workplace was more effective to increase physical activity at daily life while aerobic training is more effective for weight loss (AU) | |
