Introduction:

To control gestational obesity, it is necessary to design and implement interventions to improve the quality of diet and physical activity. The objective of the study was to evaluate the efficacy of a psychoeducational nursing intervention for the control of gestational weight in Mexican pregnant women.

Methods:

quasi-experimental study. The sample consisted of 34 participants; n1=17 y n2=17. The psychoeducational intervention consisted of 12 sessions, which included educational, cognitive behavioral techniques and prenatal yoga, for eight weeks. The control group received routine care and a prospectus additional healthy nutrition. We realized anthropometric measurements before and after the intervention, as well as the retention rate in the intervention and the satisfaction of the participants.

Results:

Pregnant women who participated in the intervention had less gestational weight gain than those in the control group ( D̅1 = 5.17 ± 3.01 vs. ( D̅2 = 8.03 ± 4.06; t = -2.32, gl = 32, p = .026). The intervention was feasible, given that 80% complied with the scheduled sessions and satisfactory acceptability, 76.5% of the participants mentioned that the quality of the program was excellent and 100% mentioned that they received the help they expected.

Conclusion:

The psychoeducational intervention favors gestational weight control in the experimental group compared to the control group. Psychoeducational interventions are recommended for the management of weight gain during pregnancy.
