Lower education predicts poor response to dietary intervention in pregnancy, regardless of neighbourhood affluence: secondary analysis from the ROLO randomised control trial.

摘要: Objective To determine if response to a low glycaemic index (GI) dietary intervention, measured by changes in intake and gestational weight gain, differed across women of varying socio-economic status (SES). Design Secondary data analysis the ROLO randomised control trial. The intervention consisted two-hour low-GI education session early pregnancy. Change GI was using 3 d food diaries pre- post-intervention. Gestational gain categorised as per 2009 Institute Medicine guidelines. SES neighbourhood deprivation. Setting National Maternity Hospital, Dublin, Ireland. Subjects Women (n 625) recruited Results significantly reduced excess (EGWG) among with third level residing both disadvantaged (GI, mean (sd), v. control: −3·30 (5·15) −0·32 (4·22), P=0·024; EGWG, n (%), 7 (33·6) 22 (67·9); P=0·022) advantaged areas (GI: −1·13 (3·88) 0·06 (3·75), P=0·020; EGWG: 41 (34·1) 58 (52·6); P=0·006).
