This measurement will start by performing a blood pressure measurement at the first phase. In the second phase the pulse wave recording for pulse waveform analysis is performed. First the device will inflate back to the measured diastolic value and register the pulse waves and second, the device inflates further to the suprasystolic value (to the measured systolic value +35 mmHg), occluding the brachial artery completely in this way and registers the pulse waves.'}, {'measure': 'Echocardiography (age 2.5-4 years)', 'timeFrame': '12 months', 'description': 'Echocardiography will be performed in a supine position. Three ECG electrodes will be attached on the skin. The child can watch a movie during the measurements. Using M-mode and Tissue Doppler Echocardiography several measurements of the systolic and diastolic function of the right and left ventricle will be performed.'}, {'measure': 'Anthropometry (both age categories)', 'timeFrame': '12 months', 'description': 'Body height and weight will be measured to the nearest 0.1 cm and 0.1 kg respectively without wearing shoes. Distance between the jugular fossa and symphysis will be measured (needed for calculation of pulse wave velocity). Waist circumference will be measured twice at the bare skin using a non-elastic measuring tape, between the superior iliac anterior spine and the lowest rib in a horizontal line, at the end of a normal expiration. Hip circumference will be measured twice over light clothing at the most posterior point of the buttocks. Thoracic circumference will be measured at the end of the expiration and signs of respiratory disease will be noted.'}, {'measure': 'Carotid intima media thickness (age 6-8 years)', 'timeFrame': '12 months', 'description': 'The carotid IMT will be determined by using ultrasound based on the gold standard Wall Track System (Art.lab System, Esaote and the Cardiovascular Research Institute Maastricht).'}, {'measure': 'Fat mass determination (6-8 years)', 'timeFrame': '12 months', 'description': 'The intra-abdominal fat will be assessed by ultrasound by determination of the distance between the posterior side of the linea alba and the anterior vertebrae.

The venipuncture will be performed in a vein in the cubital fossa. Two different tubes of blood will be drawn, one sodium-heparin and one lithium-heparin tube, with in total a maximum of 19 cc blood.

Although mostly known for its reproductive consequences, PCOS is associated with metabolic abnormalities related to insulin resistance and obesity. Children born from PCOS mothers are considered to be at risk for early insulin resistance, leading to development of PCOS and metabolic abnormalities in childhood and adolescence. Obesity and insulin resistance are considered as states of low- and pro-inflammation associated with endothelial dysfunction. In addition, it has been shown that endothelial dysfunction develops from the first decade of life in response to genetic and environmental risk factors. Therefore, offspring of women with PCOS may be at increased risk for vascular disease later in life. Moreover, some evidence suggests that early life respiratory disease also contributes to later life cardiovascular consequences. The number of studies on offspring of PCOS mothers is low and a systematic follow up of children born form PCOS mothers has not been performed yet. the investigators propose a systematic evaluation of cardiometabolic and pulmonary health characteristics of children (aged 2,5-8 years) born from mothers diagnosed with PCOS. A saliva sample will be performed to determine the biochemical androgenic status of the children. Mothers of these children have undergone standardized phenotyping prior to conception; the investigators will therefore be able to correlate the metabolic status of the mother around the time of conception and the cardiometabolic and pulmonary health of their offspring.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD'], 'maximumAge': '8 Years', 'minimumAge': '30 Months', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Cases Children born from mothers who are diagnosed with PCOS at the UMCU will be asked to participate.
