About this study
Official title: Physical Exercise Influence on Maternal, Perinatal Outcomes and Quality of Life Among Overweight and Obese Pregnant Women:
Objective: To evaluate the association between physical exercise for obese or overweight women and the maternal, perinatal outcomes and perception of these women about their quality of life.
Methods: A randomized controlled clinical trial with 78 pregnant women. Overweight or obese (BMI ≥ 26 kg / m²), gestational age between 14 and 24 weeks and from age 18 years were included. They will be divided into two random groups: one which will an exercise program under supervision and guidance received from home exercises (study group) and another that followed the standard routine prenatal care service (control group). Both groups will receive standardized nutritional counseling by the department of nutrition and dietetics and a questionnaire measuring quality of life WHOQOL-short at 14 - 24 weeks and at 36 weeks of pregnancy. The intervention results will be analyzed by intention to treat. A P value less than 0.05 will be used to determine statistical significance.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
physical exerciseOther
The exercise protocol was done under supervision once a week. Pregnant women have been told to do some exercise three more times during the week unsupervised and may be the protocol of exercises or walk in mild to moderate intensity.
The exercise protocol lasted 50 minutes with 10 minutes of stretching overall, 30 minutes of exercise for muscle strengthening and 10 minutes of relaxation.
These women also received nutrition counseling and prenatal care.

|---|---|---|
| physical exercise | Other | exercise on obese and overweight pregnant women, routine prenatal care and nutritional counseling Receives: Other: physical exercise |
| no exercise | No intervention | Routine prenatal care and nutritional counseling. No exercise |
What is being measured
The primary outcome is the main question the study is designed to answer.
Gestational Weight Gain
Gestational weight gain is the difference between the prepregnancy weight and the last weight measure at the end of pregnancy
Measured: baseline and at 40 gestational weeks
Weight Gain During the Program
Weight gain during the program was the difference between the weight measured at study entry and final consultation weight, measured by a mechanical scale, in kilos and grams
Measured: at the 14 to 40 gestational weeks
Secondary outcomes (1)
Quality of Life Through World Health Organization Quality of Life Abbreviated Questionnaire WHOQOL-Bref)
All pregnant women responded to the quality of life WHOQOL-bref questionnaire, at study inclusion and at the completion of 36 gestational weeks. The domains of these questionnaires were calculated on a scale of zero (the worse quality of life) to 100 points (the better quality of life).
Measured: at the 14 and at the 40 gestational weeks

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Objective: To evaluate the association between physical exercise for obese or overweight women and the maternal, perinatal outcomes and perception of these women about their quality of life.
Methods: A randomized controlled clinical trial with 78 pregnant women. Overweight or obese (BMI ≥ 26 kg / m²), gestational age between 14 and 24 weeks and from age 18 years were included. They will be divided into two random groups: one which will an exercise program under supervision and guidance received from home exercises (study group) and another that followed the standard routine prenatal care service (control group). Both groups will receive standardized nutritional counseling by the department of nutrition and dietetics and a questionnaire measuring quality of life WHOQOL-short at 14 - 24 weeks and at 36 weeks of pregnancy. The intervention results will be analyzed by intention to treat. A P value less than 0.05 will be used to determine statistical significance.
