Abstract：Objective A cross-sectional study was conducted to assess the aquatic foods intake among pregnant women residing in coastland, lakeland, and inland area of China. Methods 804 mid-pregnancy [(17.0 ± 2.0) weeks] and late-pregnancy [(39.0 ± 2.0) weeks] women from Weihai city (coastland), Yueyang city (lakeland) and Baotou city (inland) were enrolled and surveyed during May to July 2014; eligible women were 18~35 years old, local permanent residents and had singleton pregnancy, and women were excluded if they had been diagnosed with serious heart, liver, renal and pulmonary diseases, mental disorders, or sever vomiting after 16 weeks of gestation, and had aquatic foods allergy. An iPad-based electronic food frequency questionnaire (FFQ) was applied to collect information on the aquatic foods consumed by each participant in the past month. Kruskal-Wallis H and Wilcoxon rank sum test were used to test the inter-region and inter-pregnancy stage differences in the consumption of aquatic foods. Results The median intake of total aquatic foods in coastland, lakeland and inland women were 59.2 g/d, 46.7 g/d, 16.7 g/d, respectively. The total aquatic foods intake in inland women was lower than that in coastland and lakeland women (P<0.05). The medians of total aquatic foods intake for mid-pregnancy women in coastland, lakeland and inland area were 51.7 g/d, 51.7 g/d, and 16.7 g/d, and for late-pregnancy women, 80.8 g/d, 42.5 g/d, and 16.7 g/d, respectively. In the coastland area, the total aquatic foods intake was higher in late-pregnancy women than in mid-pregnancy women (P<0.001), but significant differences were not observed for women lived in the lakeland and inland. Multiple linear regression showed that, in addition to the geographical factor, annual family income per capita and ethnicity was also significantly associated with the total aquatic foods intake of pregnant women (P<0.05). The types of most frequently consumed aquatic foods differed by the region. On average, 10 types of aquatic foods were commonly consumed in the coastland, 7 in the lakeland and 5 in the inland (P<0.05). The top three aquatic foods were clam, prawn, and mantis shrimp in the coastland; goldfish carp, crayfish and eel in the lakeland; common carp, goldfish carp and dried hairy shrimp in the inland. Conclusion The aquatic foods intake for pregnant women lived in both coastland and lakeland accorded with available recommendations (China’s recommendation for general population:40.0-75.0 g/d [1]; the U.S recommendation for pregnant/lactating women:32.4-48.6 g/d [2]), but for women lived in the inland area was far below the recommended levels, indicating a need of strengthening dietary guidance and health education especially for pregnant women lived in the inland area.
