Lifestyle, Education, Activity, Nutrition (LEAN) Into Pregnancy: A Randomized Controlled Trial Investigating the Impact of Healthy Lifestyle Education During Preconception and Early Pregnancy on Cardiovascular and Pregnancy Outcomes

Overview

The goal of this randomized controlled clinical trial is to determine if healthy lifestyle education can help improve cardiovascular health and reduce pregnancy complications in women during the preconception period or early pregnancy. The main aims include: 1. Determine the feasibility and acceptability of the LEAN into pregnancy study. 2. Determine the impact of healthy lifestyle education on Life's Essential 8 cardiovascular health score. 3. Determine the impact of health lifestyle education on adverse pregnancy outcomes, specifically gestational diabetes and preeclampsia. A total of 200 participants will be randomly assigned to receive healthy lifestyle education in addition to routine care, or routine care alone. Participants will be asked to participate in the following activities: * Blood draws to test hemoglobin A1c and lipids * Surveys about diet, physical activity, sleep, and tobacco use * Gaples Nutritional Education Modules (if applicable)

Detailed description

Studies investigating adverse pregnancy outcomes have shown contributing effects from increased rates of diabetes, hypertension, and abnormal cholesterol and cardiovascular disease events. Previous studies have additionally shown that lifestyle modifications such as the DASH diet, regular exercise, and reduction in stress can lower blood pressure, lower LDL cholesterol levels, and decrease poor health behaviors that are linked to cardiovascular disease. However, studies have failed to quantify the effects of lifestyle modifications on more short-term cardiovascular health that may increase adverse pregnancy outcomes. By shifting the focus from cardiovascular disease treatment to positive health promotion, it promotes a paradigm shift to focus on prevention of disease and improved societal health overall. Preliminary data from our group showed significant correlations between preeclampsia and lower availability of healthy food, which is one of the factors quantified in Life's Essential 8. A major gap in the literature remains lifestyle interventions that can lead to risk factors for cardiovascular health in pregnant populations during gestation and also in the preconception period. We believe that lifestyle interventions preconception or during pregnancy can improve cardiovascular health during gestation and reduce adverse pregnancy outcomes.

We hypothesize that the implementation of specific educational modules surrounding diet and exercise and repeated patient interaction will improve Life's Essential 8 cardiovascular score and, in those who are pregnant, potentially reduce the risk for gestational diabetes and preeclampsia.

Interventions

• Other Healthy lifestyle education
  Healthy lifestyle education via nutritional educational modules from the Gaples Institute.

Primary outcome measures

• Feasibility of the LEAN into Pregnancy Study [Time frame: From enrollment through the end of intervention at 3 months.]

Secondary outcome measures (4)

• Life's Essential 8 [Time frame: At enrollment and after intervention at 3 months.]
• Incident rate of gestational diabetes among participants who become pregnant. [Time frame: Up to 2 years after enrollment]
• Acceptability of the LEAN into Pregnancy Study [Time frame: 3 months from enrollment (end of intervention)]
• Incident rate of hypertensive disorders of pregnancy in participants who become pregnant [Time frame: Up to 2 years after enrollment]

Eligibility criteria

Inclusion criteria
