Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Maternal gestational weight change	Maternal weight prior to pregnancy (or within 8 weeks of pregnancy), at around 20, 26, 32 weeks' gestation, before delivery and one month postpartum will be determined by digital scales, changes in maternal weight during pregnancy will be recorded in kg.	From pregnancy until one month postpartum
Primary	Newborn size	Weight (kg) will be measured with digital scales and height/length (cm) will be measured in supine with tape, comparing against reference to derived gestational age and sex-specific growth parameter Z-scores. To identify whether the neonates was small/appropriate/large for gestational age.	Day 1 after birth
Primary	Neonatal skinfold thickness (at birth)	Measured with skinfold caliper, a summation of skinfold thickness at several body sites including triceps, biceps, subscapular, suprailiac and thigh, will be derived in cm.	Day 1 after birth
Primary	Maternal blood lipid profile postpartum (3 years)	Measured by autoanalyzer, total lipids (total cholesterol, triglycerides, high/low density protein cholesterol) expressed in mmol/L.	Three years after delivery
Primary	Maternal blood glucose profile postpartum (3 years)	Measured by autoanalyzer, blood glucose level in mmol/L.	Three years after delivery
Primary	Maternal blood insulin profile postpartum (3 years)	Measured by commercial ELIZA kit, total and free insulin in pmol/L.	Three years after delivery
Primary	Child blood lipid profile (3 years)	Measured by autoanalyzer, total lipids (total cholesterol, triglycerides, high/low density protein cholesterol) expressed in mmol/L.	At three years of age
Primary	Child blood glucose profile (3 years)	Measured by autoanalyzer, blood glucose level in mmol/L.	At three years of age
Primary	Child blood insulin profile (3 years)	Measured by commercial ELIZA kit, total and free insulin in pmol/L.	At three years of age
Primary	Child growth parameters (3 years)	Weight measured with digital scales in kg, length measured in standing position in cm, using weight and length to derived body mass index, comparing against age and sex-specific references for Z-score.	At three years of age
Primary	Incidence of pregnancy complications	Incidence of physician-diagnosed pregnancy complications, including gestational diabetes mellitus, hypertensive disorders	From 20 weeks' gestation until one month postpartum
Secondary	Child skinfold thickness (6 months)	Measured with skinfold caliper, a summation of skinfold thickness at several body sites including triceps, biceps, subscapular, suprailiac and thigh, will be derived in cm.	At six months of age
Secondary	Child skinfold thickness (1 year)	Measured with skinfold caliper, a summation of skinfold thickness at several body sites including triceps, biceps, subscapular, suprailiac and thigh, will be derived in cm.	At one year of age
Secondary	Child skinfold thickness (3 years)	Measured with skinfold caliper, a summation of skinfold thickness at several body sites including triceps, biceps, subscapular, suprailiac and thigh, will be derived in cm.	At three years of age
Secondary	Child skinfold thickness (6 years)	Measured with skinfold caliper, a summation of skinfold thickness at several body sites including triceps, biceps, subscapular, suprailiac and thigh, will be derived in cm.	At six years of age
Secondary	Child growth parameters (6 months)	Weight measured with digital scales in kg, length measured with tape in supine position in cm, using weight and length to derived body mass index, comparing against age and sex-specific references for Z-score.	At six months of age
Secondary	Child growth parameters (1 year)	Weight measured with digital scales in kg, length measured with tape in supine position in cm, using weight and length to derived body mass index, comparing against age and sex-specific references for Z-score.	At one year of age
Secondary	Child growth parameters (6 years)	Weight measured with digital scales in kg, length measured in standing position in cm, using weight and length to derived body mass index, comparing against age and sex-specific references for Z-score.	At six years of age

Secondary	Child blood insulin profile (6 years)	Measured by commercial ELIZA kit, total and free insulin in pmol/L.	At six years of age
Secondary	Neurological development of child (1 year)	Assessed by using Gesell testing, which measures the child's cognitive, language, motor (gross & fine) and social-emotional responses. Higher score in each domain is desired, there is no upper limit. Overall score of less than 86 indicates suspected developmental retardation.	At one year of age
