Associations between prenatal diet quality and gestational weight gain.
BACKGROUND
Improving prenatal diet quality may promote appropriate gestational weight gain (GWG).


AIM
To examine relationships between dietary quality in the second and third trimesters of pregnancy and GWG.


METHODS
Participants' (n = 41) dietary intake was assessed at 14-20 and 35 weeks gestation via the Automated Self-Administered 24-h recall (ASA-24). Kilocalories and Healthy Eating Index (HEI-2015) scores were calculated and associations with GWG were explored via linear regression.


RESULTS
Participants reported consuming 2139 ± 719 and 2085 ± 704 kilocalories at 18 and 35 weeks, respectively. HEI-2015 total scores at 18 (55.6 ±12.6) and 35 weeks gestation (56.6 ± 14.1) indicated a need for improvement. Greens and beans component score at 35 weeks was the only diet quality score associated with GWG.


CONCLUSIONS
GWG was not associated with most diet quality indices. However, vegetable intake may help to attenuate GWG. Future research should seek to elucidate relationships between GWG and dietary quality/intake to provide valuable insight for researchers and clinicians.
