Outcomes
Primary outcome [1] 298002 0
Prevalence of metabolic syndrome will be assessed.

The height, weight and waist circumference will be measured. Blood pressure (BP) will be measured 20 minutes after resting and in the absence of morning caffeine and cigarettes. If the resting BP greater than 140/90mmHg or if women had experienced a complication in the index pregnancy, the women will be provided a 24 hour ambulatory BP monitor. Hypertension will be diagnosed if more than 25% of the 24 hour BP records are greater than 140/90mmHg during the day and greater than 120/80mmHg during the night and the average BP over the 24 hour period is greater than 130/80mmHg. Urine will be collected in the 24 hours preceding the measurements. The 24 h urine sample will be assayed for albumin, protein, and creatinine output to calculate microalbuminuria corrected for creatinine output (g/mol creatinine) and total protein level (g/24 h). A fasting blood sample will be collected to measure glucose, insulin, glycosylated haemoglobin (HbA1c), LDL cholesterol, HDL cholesterol, triglycerides, blood urea, electrolytes, creatinine and uric acid. The homeostasis model assessment (insulin [mU/L] x glucose [mmol/L]/22.5) will be used to estimate the degree of insulin resistance (HOMA-ir). HbA1c will be expressed as HbA1c [mol]/Hb [mol] x 100%. MetS will be defined based on the guidelines of the World Health Organization as follows): the presence of hyperinsulinemia (fasting insulin equal to 9.2mU/L, fasting blood glucose equal to 6.1 mmol/L, or HOMA-ir equal to 2.2) along with any 2 or more of the following: (1) BMI equal or greater than 30 kg/m2, (2) dyslipidemia (triglycerides equal or greater than 1.69 mmol/L or high-density lipoprotein cholesterol equal or greater than 0.9 mmol/L), (3) hypertension: systolic BP equal or greater than 140 mmHg and/or diastolic BP equal or greater than 85 mmHg or the use of antihypertensive medication, and (4) microalbuminuria (equal or greater than 2.5 g/mol creatinine) or proteinuria (equal or greater than 0.30 g/24 h).

Summary
Brief summary
There is evidence from around the world that women who suffered from pregnancy complications including preeclampsia (PE) and gestational diabetes mellitus (GDM) and those who delivered a small-for-gestational-age infant (SGA) or had a spontaneous preterm birth (sPTB) are more likely to develop various cardiovascular and metabolic diseases later in life and that these occur at a younger age than in women who had uncomplicated pregnancies. Despite increasing knowledge of the long term risks following pregnancy complications to women’s health, current clinical practice does not include follow up of women after these pregnancy complications.
The proposed study is a follow up of women recruited to the Adelaide cohort of the SCOPE study. The SCOPE study is an international, multi-centre, prospective cohort study which aimed to develop screening tests to predict PE, SGA infants and sPTB across different populations. SCOPE recruited 1164 mother-father-baby trios to the Adelaide SCOPE cohort between September 2005 and September 2008. Of the 1164 women who were recruited to the Adelaide SCOPE cohort, 861 had uncomplicated pregnancies, 93 developed PE, 118 had gestational hypertension, 95 normotensive women delivered SGA babies, 69 delivered preterm and 51 had GDM.
All women will be contacted 10-11 years after delivery of the first child. Those consenting will be recruited. The women will be screened for cardiovascular and metabolic risk factors,depression and quality of life. Information will be obtained on diet, exercise and general health. The SF12 questionnaire will be used to assess quality of life. The PHQ9 and GAD 7 questionnaires will be used to assess depression and general anxiety. The height, weight and waist circumference will be measured. Blood pressure (BP) will be measured 20 minutes after resting and in the absence of morning caffeine and cigarettes. If the resting BP is >140/90mmHg or if women had experienced a complication in the index pregnancy, the women will be provided a 24 hour ambulatory BP monitor. Hypertension will be diagnosed if >25% of the 24 hour BP records are >140/90mmHg during the day and >120/80mmHg during the night and the average BP over the 24 hour period is >130/80mmHg. A fasting blood sample will be collected to measure glucose, insulin, glycosylated haemoglobin (HbA1c), LDL cholesterol, HDL cholesterol, triglycerides, blood urea, electrolytes, creatinine and uric acid. Women with risk factors will be referred for specialist care if necessary.
