Climate-Safe Pregnancy Intervention for Women With Preeclclampsia
A Climate-Related Nursing Intervention to Improve Knowledge, Health Beliefs, and Protective Behaviors in Women With Preeclampsia: A Randomized Controlled Trial
This randomized controlled trial aims to evaluate the effectiveness of a climate-related nursing intervention in improving pregnancy-specific climate change knowledge, health beliefs, and protective behaviors among pregnant women diagnosed with preeclampsia. Climate change, particularly extreme heat exposure and air pollution, increases maternal and fetal health risks and may worsen hypertensive disorders of pregnancy such as preeclampsia. Despite growing evidence linking climate-related exposures to adverse pregnancy outcomes, there is limited intervention research addressing climate adaptation in high-risk pregnant women.
A total of 104 pregnant women with preeclampsia receiving antenatal care at Benha University Hospitals, Egypt, were randomly assigned in a 1:1 ratio to either the intervention group or the control group. The intervention group received routine antenatal care plus a structured nursing educational program entitled "Climate-Safe Pregnancy: Adaptation and Self-Protection Guidelines for Women with Preeclampsia," while the control group received routine antenatal care alone.
The intervention included an individualized core educational session, structured educational materials, and a booster follow-up session. Outcomes were assessed at baseline, post-intervention, and follow-up using the Pregnancy-Specific Climate Change Awareness Scale (PSCCAS), the Health Belief Model-Based Climate Change and Preeclampsia Scale (HBM-CCP), and the Climate Change Health Protection Behaviors Scale (CCHPB).
The study aims to provide evidence for theory-based nursing interventions that support maternal adaptation to climate-related health risks and improve antenatal care outcomes for women with preeclampsia.

Detaljert beskrivelse
This study is a two-arm, parallel-group randomized controlled trial conducted to evaluate the effectiveness of a structured climate-related nursing intervention for pregnant women diagnosed with preeclampsia. The study was conducted at the antenatal outpatient clinic of Benha University Hospitals, Egypt, between July and December 2025. Preeclampsia is a major hypertensive disorder of pregnancy associated with significant maternal and fetal morbidity. Climate-related exposures such as extreme heat, dehydration, air pollution, and environmental stressors may further increase maternal vulnerability and worsen pregnancy outcomes. Despite growing evidence linking climate change to adverse obstetric outcomes, there is limited intervention research addressing climate adaptation among women with preeclampsia, particularly in low- and middle-income countries.
A total of 104 eligible pregnant women diagnosed with preeclampsia were recruited and randomly allocated in a 1:1 ratio into intervention and control groups using computer-generated block randomization with sealed opaque envelope allocation concealment. The intervention group received routine antenatal care in addition to a structured nursing intervention entitled "Climate-Safe Pregnancy: Adaptation and Self-Protection Guidelines for Women with Preeclampsia." The intervention included an individualized 45-minute core educational session covering climate-related maternal risks, protective behaviors, problem-solving strategies, and self-efficacy enhancement, followed by structured educational materials and a booster reinforcement session delivered after 10 days.
The control group received routine antenatal care only, including standard monitoring, medication management, and routine counseling regarding preeclampsia and antenatal follow-up. The primary outcome was pregnancy-specific climate change knowledge measured using the Pregnancy-Specific Climate Change Awareness Scale (PSCCAS). Secondary outcomes included climate-related health beliefs measured using the Health Belief Model-Based Climate Change and Preeclampsia Scale (HBM-CCP), and climate change health protection behaviors measured using the Climate Change Health Protection Behaviors Scale (CCHPB).
Outcome measures were assessed at baseline, post-intervention, and four-week follow-up. The study aimed to generate evidence for theory-based nursing interventions that improve maternal adaptation to climate-related health risks and strengthen antenatal care outcomes for women with preeclampsia.

Pregnancy-Specific Climate Change Knowledge
Tidsramme: Baseline, 2 weeks post-intervention, and 4 weeks follow-up
|
Pregnancy-specific climate change knowledge measured using the Pregnancy-Specific Climate Change Awareness Scale (PSCCAS), a 21-item validated instrument assessing general climate change awareness, maternal health awareness, and fetal health awareness.
Higher scores indicate greater awareness and knowledge regarding climate-related maternal and fetal risks.
