Abstract

BACKGROUND AND OBJECTIVES:

Few studies have described the socioeconomic disparity of dietary quality in Northwest China. The present study aimed to evaluate the diet quality of pregnant women in Shaanxi province of Northwest China by using the Diet Balance Index for Pregnancy (DBI-P) and explored the relationships with socioeconomic status (SES).

METHODS AND STUDY DESIGN:

A cross-sectional analysis of data from 7,630 women who were pregnant during 2012-2013 was performed. Dietary intake during the whole pregnancy was assessed by FFQ within 12 months (median, 3 months; 10th-90th percentile, 0-7 months) after delivery. Diet quality evaluated by the DBI-P was related to socioeconomic factors.

RESULTS:

Most women had insufficient consumption of vegetables (72.27%), dairy (89.58%), meat (82.07%), fish and shrimp (92.23%), eggs (62.54%), and dietary variety (97.92%). 67.76% of women had excessive intake of grains, and 87.77% and 69.79% of participants had surplus consumption of edible oil and salt respectively. Women with higher education, occupation and household wealth index (HWI) consumed more vegetables, fruit, dairy, soybean and nuts, meat, fish and shrimp, eggs, edible oil, alcohol and dietary variety but less grains and salt. After adjusting for confounders, education, occupation and HWI were negatively associated with the level of inadequate dietary intake. Conversely, individuals with medium HWI had higher level of excessive dietary intake compared to low HWI groups.

CONCLUSIONS:

The diet quality of pregnant women in Northwest China was associated with SES. Socioeconomic disparities in diet quality should be considered when planning nutrition interventions for pregnant women.
