Data Grouped By:County, Breastfeeding (any) duration (grouped), among initiators

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.

Map Not Available

The data are grouped by 2 or more dimensions. Maps can only be displayed when the data are grouped by a single geographical dimension. If you would like a map, you will need to return to the query definition page and set the Display By (category) to the "Geography" selection and clear the Group By (series) selection. Then resubmit the query.

Question Wording:

Based on a series of questions. Baby's age at time questionnaire was completed. Did you ever breastfeed or pump breast milk to feed your new baby after delivery, even for a short period of time? Are you currently breastfeeding or feeding pumped milk to your new baby?

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 guidelines, a minimum of 30 respondents (women with a recent live birth) must answer a question in order for it to be reported. Where the number of respondents is below 30, ** 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.

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%.
