Data was entered using CSPro 4.0 software (US Census,2011) and data cleaning was performed using SPSS version 19. Missing data and outliers were checked against hard-copy questionnaires to ensure accurate data entry.Data from 980 pregnant women who participated in the survey are included in these analyses. One case was excluded from further analyses due to a high proportion(>75%) of missing data. Descriptive statistics, including simple proportions, n (%), for categorical variables and mean with standard deviation for continuous variables,were noted for participant baseline characteristics.
