Chart Not Available
The data are grouped by more dimensions than the chart is capable of displaying. If you would like this chart you will need to remove one or more grouping selections on the query definition builder page and then resubmit the query request or choose a different chart that supports multiple dimensions.Question Wording:
During the month before you got pregnant with your new baby, how many times a week did you take a multivitamin, a prenatal vitamin, or a folic acid vitamin?Statistical Stability
Statistical stability, reported in the data table, is based on a statistic called the "Relative Standard Error," or RSE, which is the standard error expressed as a proportion of the point estimate (e.g., 30% of the point estimate)."Stable" is displayed when the relative standard error (RSE) is below 0.30 and the count or rate may be considered stable.
"Unstable" is displayed when the RSE is 0.30-0.50. An unstable count or rate may fluctuate widely across time periods due to random variation (chance).
"Very Unstable" is displayed when the RSE is greater than 0.50. A very unstable count or rate should not be used to inform decision. Problems with statistical instability typically occur when there is a small number of health events in a small population. You may combine years or otherwise increase the population size used in the query to achieve a more stable count or rate.
"No Variance" is displayed when there is no record, or only one record in the sample population, for the selected indicator and demographics.
Suppression of Estimates
According to CDC PRAMS guidelines, a minimum of 30 respondents must answer the question in order for it to be reported. Where the number of respondents is below 30, or the RSE is greater than 0.50, ** will appear in the table.Weighted Survey Data
The percentages reported above have been produced by weighting the sample so that the results better represent the population of Hawaii. Numerator and denominator data have been rounded to the nearest 100. In cases where the numerator is 49 or less, it is displayed as 50.Survey Sample
PRAMS uses a two-stage, stratified random sampling method to identify the sample. The sampling frame is drawn from birth certificates. Each month, approximately 200 women who are 2 to 4 months post-delivery are chosen. The sample includes only residents of Hawaii who had a recent live birth in the state. The results are weighted to ensure accurate representation of the population.Average Annual Population Estimate
The denominator includes all survey respondents except those with missing, don't know and refused answers. If the query was limited to a particular sub-population-group, only those respondents are included in the denominator.Asymmetric Confidence Intervals
The confidence bounds are asymmetric. They do not extend evenly above and below the percentage, especially as the percentage gets close to 0% or 100%.- Hawaii Pregnancy Risk Assessment Monitoring System, Hawaii State Department of Health, Family Health Services Division, Maternal and Child Health Branch.
