Practice and effects of pregnancy weight control program based on structure-process-outcome model

Abstract

Objective To evaluate the effects of pregnancy weight control program based on structure-process-outcome model to improve women's health status and pregnancy outcomes. Methods On the basis of Donabedian's structure-process-outcome quality of care model, a pregnancy weight control program designed and carried out for the middle and late pregnancy. The structure, process and outcome of the pregnancy weight control program were evaluated to ensure the quality of the pregnancy weight control program. In addition, the women's pregnancy outcomes were investigated after intervention. Results the prenatal BMI in the intervention group [(23.06±1.11)kg/m2 ] were lower than those in the control group [(25.52±1.89)kg/m2 ], and the incidence of cesarean section (including cesarean section without indication), neonatal macrosomia, labor block, neonatal asphyxia, postpartum hemorrhage, pregnancy induced diabetes and hypertension in the intervention group were significantly lower than those in the control group, P<0.01 or 0.05. Conclusion Donabedian's structure-process-outcome quality of care program is an effective approach to improve women's pregnancy outcomes.
