Clinical Trial Summary

Suspected preterm labour (SPL), define as the presence of regular and painful uterine contractions and cervical shortening, constitute a prenatal insult with potential long-term consequences. However, despite recent evidence demonstrating a suboptimal neurodevelopment at 2 years in this population, it remains under-recognized as a significant risk factor for neurodevelopmental disorders or other chronic diseases. The objective of this study is to assess the impact of suspected preterm labour during pregnancy on cardiometabolic profile and neurodevelopment during childhood (6-8 years). Prospective cohort study including children whose mothers suffered a suspected preterm labor during pregnancy and paired controls. A neurodevelopment, cardiovascular and metabolic assessment at 6-8 years of age will be performed. A trained psychologist will carry out the neurodevelopment assessment. Body composition and physical fitness assessment will be performed by one trained pediatrician and nurse. Finally, cardiovascular assessment, including echocardiography and blood pressure, will be performed by two pediatric cardiologists. Data regarding perinatal and postnatal characteristics, diet, lifestyle and weekly screen time of the child will be obtained from clinical histories and direct interviews with the families. Primary outcome measures will include body mass index and adiposity, percentage of fat mass and total and regional lean mass, bone mineral content and density, cardio-respiratory resistance, isometric muscle strength, dynamic lower body strength, systolic and diastolic blood pressure, left ventricle (LV) systolic and diastolic function, general intelligence index, visuospatial working memory span, visual development test, visual acuity, index of emotional and behavioral problems.

Outcome

Type Measure Description Time frame Safety issue
Primary Percentage of fat mass and total and regional lean mass 6-8 years
Primary Body mass index and adiposity 6-8 years
Primary Cardio-respiratory resistance After fitting the safety harness, the test began when the participants were able to walk easily on the treadmill (Quasar Med 4.0, h/p/cosmos, Nußdorf, Germany). The protocol started with a speed of 2.4 km/h, increasing by 0.8 km/h every 2 min until the participants were unable to walk or reached a speed of 4.8 km/h. Then, the slope was increased by 4% every minute until exhaustion or up to a maximal slope of 24%. The respiratory gas exchange data were measured breath-by-breath using open-circuit spirometry (Oxycon Pro, Jaeger/Viasys Healthcare, Hoechberg, Germany). Maximal oxygen uptake (VO2max) values were averaged over consecutive 15 s periods. 6-8 years
Primary Systolic and diastolic blood pressure 6-8 years
Primary Left ventricle (LV) systolic and diastolic function End-diastolic and end-systolic diameter, septum and posterior wall thickness, heart rate, ejection fraction (by Teicholz and biplane Simpson methods), mitral annulus S´ wave velocity (tissue doppler), mitral annulus E and A waves velocity (pulse-wave doppler), E´ and A´ waves velocity (tissue doppler), TEI index (tissue doppler) and LV strain and strain rate at three apical views (speckle tracking). 6-8 years
Primary General intelligence index 6-8 years
Primary Visual development test 6-8 years
Primary Global index of problems 6-8 years
Primary Index of emotional problems 6-8 years
Primary Index of behavioral problems 6-8 years
