Because of its high prevalence and possible problems for pregnant women and their offspring,
gestational diabetes is a global health concern. As a result, patient education is one of the most
important factors in increasing women's knowledge and habits. Early detection of high-risk factors
for gestational diabetes can be prevented by educational programs designed and implemented to
decrease the high prevalence and prevent complications. Aim: To evaluate the effect of intervention
PRECEDE model on knowledge and practice of preventive behaviors among high-risk pregnant
women regarding gestational diabetes. Subjects and method: Design: Quasi-experimental research
design pre-post-test was used to achieve the aim of this study. Settings: The study was applied in
the antenatal outpatient clinics at Beni-Suef University Hospitals. Sample: A purposive sample of
200 pregnant women diagnosed as high-risk for gestational diabetes was recruited from the selected
settings. Tools: Four tools were used: (1) a Structured interviewing questionnaire, (2) Predisposing,
Enabling, and Reinforcing Questionnaire (PRECEDE model questionnaire), (3) a High-risk
pregnant women's reported practices questionnaire of gestational diabetes preventive behavior, and
(4) High-risk pregnant women's attitude questionnaire regarding gestational diabetes prevention.
Results: The current results revealed that the mean score of knowledge, enabling factors, and
reinforcing factors have been increased with statistical significance immediately and after one
month of the intervention. High-risk pregnant women had adequate practices toward gestational
diabetes preventive measures one-month post-intervention compared to pre-intervention. High-risk
pregnant women had a positive attitude toward gestational diabetes preventive measures one-month
post-intervention compared to pre-intervention. There was a statistically significant relationship
between knowledge, enabling, reinforcing factors scores, and practices scores of gestational diabetes
preventive measures throughout the intervention phases. Conclusion: It was concluded that
implementing intervention based on PRECEDE model for high-risk pregnant women was effective
in improving knowledge and practice regarding the prevention of gestational diabetes.
Recommendation: The intervention based on PRECEDE model regarding gestational diabetes
prevention should be integrated into the antenatal care for pregnant women in the different study
settings.
