Summary
Brief summary
INTRODUCTION: CHIPS-Child is a parallel, ancillary study to the CHIPS randomized controlled
trial (RCT). CHIPS is designed to determine whether 'less tight' control [target diastolic BP
(dBP) 100mmHg] or 'tight' control [target dBP 85mmHg] of non-proteinuric hypertension in
pregnancy is better for the baby without increasing maternal risk.

CHIPS-Child is a follow up study at 12 m corrected post-gestational age (± 2 m) limited to
non-invasive examination [anthropometry, hair cortisol, buccal swabs for epigenetic testing
and a maternal questionnaire about infant feeding practices and background]. Annual contact
will be maintained in years 2-5 and contact will include annual parental measurement of the
child's height, weight and waist circumference.

OBJECTIVE: To directly test, for the first time in humans, whether differential blood
pressure (BP) control in pregnancy has developmental programming effects, independent of
birthweight. We predict that, like famine or protein malnutrition, 'tight' (vs. 'less tight')
control of maternal BP will be associated with fetal under-nutrition and effects will be
consistent with developmental programming.
