摘要

Background and Objectives: Although large-scale natural disasters and the resultant changes in living environments worsen dietary habits among adults immediately after the disasters, whether this association remains for a long period is unclear. This is particularly important for recent mothers because lactating women require additional nutrition for milk production. Thus, we investigated the association of living environments with dietary habits and nutritional intake of recent mothers between four and seven years after the Great East Japan Earthquake (11th March, 2011). Methods and Study Design: We analyzed 8,551 mothers who participated to the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study. Living environments were characterized into four categories: ＂same home before the earthquake＂, ＂rental housing＂, ＂reconstructed home＂, and ＂acquaintance's home＂. Dietary habits and nutritional intake were evaluated using a food frequency questionnaire answered 12 months after their deliveries (the questionnaire was answered between March 2015 and July 2018). Results: Multiple linear regression analyses demonstrated that mothers in 'rental housing' or 'reconstructed home' had a significantly lower intake of almost all nutrients or certain nutrients, respectively, compared with those residing in 'same home before the earthquake'. However, fewer significant differences were detected between the nutritional intake of the mothers lodging in an 'acquaintance's home' and that of those living in 'same home before the earthquake'. Conclusions: Our findings indicate that living environments long-term after large-scale disasters are associated with dietary habits and nutritional intake among recent mothers.
