Objective: To determine how the quality of life of pregnant women who participate in a community program of hydrokinesis therapy for pregnant women (PHTPW) changes. Material and methods: Quasi-experimental, pre-post intervention study. This study was conducted in a community center for physical activity and health promotion. A total of 26 pregnant women, who took part in a community program of hydrokinesis therapy for pregnant women twice a week, were included. Inclusion criteria: provide medical authorization. Exclusion criteria: women who exceeded 24 weeks of pregnancy, who did not provide authorization or who refused to participate in the study. The SF-12 and EuroQol questionnaires were used as specific instruments to measure the variations of quality of life and general health status of the participants. Results: The participants had a mean age of 3274.09. The results obtained were: general physical health condition 1.73 (95% CI À3.00 to 6.46); mental health condition À2.19 (À6.67 to 2.29), EuroQol_5D À0.01 (À0.10 to 0.07) and EuroQol_VAS 0.29 (À7.39 to 7.97). Conclusions: An 8-week long community program of hydrokinesis therapy for pregnant women may stop the normal decrease in health-related quality of life in pregnant women.
