• 1 other identifier: CIRB: Ref No.: 2017/3015
• Study Type: interventional

Brief Summary

The aim of this study is to examine the effect of walking exercise in postpartum women and to evaluate the weight management intervention by using step tracker. The following hypotheses will be tested:

1. 1.The intervention in postpartum women would reduce the retention of weight gained during pregnancy and lower the risk factors of chronic disease.
2. 2.Step tracker is an effective tool in encouraging the postpartum women to do more physical activity.
3. 3.Higher physical activity is recommended for postpartum women for healthy weight lost.
