Design outcomes

Primary

MeasureTime frame
The distance measured in millimeters (mm) between the skin and vastus lateralis muscle measured using bedside ultrasound scanning at one time point

Secondary

MeasureTime frame
Body mass index (BMI) calculated using the weight in kgs divided by the height in metres squared, measured using data recorded in the clinical notes system (iCare) during the initial booking appointment (usually within 10 weeks of being pregnant)

Countries
