Not Applicable

• Conditions: Physical Activity; Obesity
• Interventions: Behavioral: individual counseling; Behavioral: group counseling; Behavioral: aerobic training

• Registration Number: NCT01567007
• Lead Sponsor: University of Sao Paulo General Hospital

Brief Summary

The purpose of this study is to evaluate the impact of different types of intervention on physical activity level and co-morbidities in women workers aged between 40 and 50 years. Method: A total of 195 sedentary women aged between 40 and 50 years and those who agreed to participate were randomized to one of the following interventions: GI = Control (n = 47), GII = Individual counseling (n = 53), GIII = Counseling group (n = 48); GIV = physical training set (n = 47). Were evaluated: Physical Activity level (steps number evaluated by a pedometer), quality of life (SF-36), body composition (BMI, waist circumference and bioelectrical impedance) and clinical variables (plasma glucose and blood pressure).

Detailed Description

Protocols and Randomization of subjects: Subjects were randomized into 4 groups: control group (GI), individual counseling (GII), group counseling (GIII) and aerobic training set (GIV). The protocols of interventions are described in detail below:

GI - Control: Comprising session of 15-20 minutes duration. It took place guidelines on physical activity, delivering a manual with general information about physical activity.

GII - Individual counseling: Consisting of three sessions within a maximum period of 3 months. We conducted a counseling, aimed at increasing physical activity, aiming to raise at least 2000 steps over the first week of monitoring. Furthermore, we discuss the importance of physical activity, such as overcoming barriers to physical activity and targets agreed between the parties. The pedometer is given along with a diary to record the number of steps and returned in the last session.

GIII - Group Counseling: The counseling was conducted in groups (10-12 individuals) for 6 sessions at weekly intervals, and two sessions with fortnightly. Each session lasts 60 minutes. The advice is aimed at behavioral changes using the following approaches: advantages and disadvantages of behavior change, how to overcome barriers to physical activity, self-monitoring of physical activity by using the pedometer and setting goals (number of steps / day) in the short term and what to do in case of relapse (not accomplish what was represented) besides livings practices. As the GII and the goal is to raise steps daily, with the main focus physical activity in leisure time and transport.

GIV - Programmed Aerobic Training: The fitness program is held two times per week with individuals and groups with three sessions lasts for 40 minutes performed on a treadmill.

All interventions lasted between 12 and 15 weeks and were carried out on time or before the commencement of work or during lunch or after work hours.
