The association between maternal blood pressures and offspring size at birth in Southeast Asian women

Table 2 Associations between blood pressures (per 1-SD increase) and size at birth ^*

Measures of size at birth	N	Peripheral systolic blood pressure (1 SD = 11.1 mmHg)	Peripheral diastolic blood pressure (1 SD = 8.3 mmHg)	Central systolic blood pressure (1 SD = 10.0 mmHg)	Central pulse pressure (1 SD = 6.5 mmHg)
Measures of size at birth	N	ß (95% CI)	ß (95% CI)	ß (95% CI)	ß (95% CI)
Weight (g)	713	−35.56 (−66.57 to −4.54)	−25.13 (−55.36 to 5.09)	−40.52 (−70.66 to −10.37)	−24.10 (−51.24 to 3.03)
Length (cm)^**	711	−0.16 (−0.32 to 0.01)	−0.10 (−0.27 to 0.06)	−0.19 (−0.36 to −0.03)	−0.14 (−0.28 to 0.01)
Head circumference (cm)^**	711	−0.09 (−0.19 to 0.02)	−0.08 (−0.18 to 0.02)	−0.12 (−0.23 to −0.02)	−0.07 (−0.16 to 0.02)
Placental weight (g)^***	699	−8.78 (−18.74 to 1.19)	−6.94 (−16.63 to 2.76)	−11.16 (−20.85 to −1.47)	−6.44 (−15.04 to 2.16)

SD, standard deviation; CI, confidence interval.
^*Multiple linear regression models were used with adjustment for baby’s sex, gestation at delivery, maternal age, ethnicity, education, parity, smoking history, height, BMI at 27 weeks gestation, coffee consumption and depression.
^**There were 2 women with missing information on length and head circumference.
^***There were 14 women with missing information on placental weight.
