Description of intervention(s) / exposure
Children born to mothers that participated in SCOPE study (ANZCTRN12607000551493). will be included in current follow up study.
Prevalence of obesity and vascular impairment among children born of complicated pregnancies including preeclampsia, gestational hypertension, small for gestational age, spontaneous preterm birth and gestational diabetes will be compared with that of children born after uncomplicated pregnancies.
Participation in the study involves a single session of approximately 1 hour.

Outcomes
Primary outcome [1] 298005 0
Prevalence of obesity will be assessed.
The height and weight will be measured from which BMI will be calculated. Overweight is defined as a BMI at or above the 85th percentile and below the 95th percentile for age and sex. Obesity is defined as a BMI at or above the 95th percentile for age and sex.
Timepoint [1] 298005 0
Prevalence of obesity will be assessed at 9-10 years of age
Secondary outcome [1] 322885 0
Prevalence of high blood pressure,
Blood pressure will be measured using a sphygmomanometer.

Statistical methods / analysis
Data of children born after complicated pregnancies will be compared with that of children born after uncomplicated pregnancies. Logistic and linear regression will be used for data analyses.

A previous study on assessing vascular function in obese kids compared to kids with normal BMI reports higher peak perfusion and longer recovery time among obese kids (Schlager et al., 2011). With the effect size observed in this study, a sample size of 800 will give 90% power at 5% significance level. Therefore, we expect the proposed study to be adequately powered.
