Abstract
OBJECTIVE: To evaluate the reliability and utility of the FIGO Nutrition Checklist to identify dietary and nutritional inadequacy in early pregnancy by comparing it against nutritional indicators and dietary quality indices (Dietary Approaches to Stop Hypertension [DASH] score, Mediterranean Diet Score [MDS], and Dietary Quality Index-International [DQI-I]), derived by a locally validated food frequency questionnaire (FFQ). METHODS: A prospective cohort study of healthy Chinese pregnant women randomly recruited between September 2017 and April 2018 at their first antenatal appointment. Women completed the FIGO Nutrition Checklist (translated into Chinese) and the FFQ. Spearman correlation was performed to examine association between the Checklist and dietary quality indices or food and nutrient intakes, calculated based on dietary data from the FFQ. RESULTS: Of 160 participants, 156 (97.5%) completed both the FIGO Nutrition Checklist and FFQ and were included. There were 148 (95%) women who reported at least one suboptimal dietary behavior using the Checklist. Checklist score was significantly associated with dietary quality indices (DASH ρ=0.344, P<0.001; DQI-I ρ=0.304, P<0.001; MDS ρ=0.164, P=0.041). The Checklist question on fruit/vegetables was significantly associated with fiber, vitamin C, and fruit and vegetable intake as calculated from the FFQ (0.325 ≤ ρ ≤0.441, P<0.001). The question on dairy intake was significantly associated with intake of calcium, milk and dairy products captured via FFQ (0.576 ≤ ρ ≤0.655, P<0.001). CONCLUSION: This study supports the use of the FIGO Nutrition Checklist to identify women with suboptimal dietary quality in early pregnancy.
