Hawaii-IBIS PRAMS Data Release Notes

General Release Notes

2019 PRAMS

The number of completed interviews for the 2019 survey is smaller than normal. The first 6 months of PRAMS 2019 data collection did not meet CDC's data quality standards due to issues with the data collection contractor. These issues were resolved, and the last 6 months met the CDC quality standards and the response rate requirement for weighted data. CDC recommended only releasing the 6-month dataset containing July - December births.

Because the sample size for 2019 is considerably smaller, many indicators may not be reportable for 2019. In these cases, users should consider aggregating years or reducing the number of filters selected to improve reliability and availability of the data.

2017-2018 PRAMS

Due to extenuating circumstances, PRAMS data collection operations were interrupted during the 2017 and 2018 calendar years. There is no survey data from this time period.

2016 PRAMS

New Demographics category

We introduced a new demographics category in this release. This section allows users to view detailed information about the PRAMS population. Please note that some of the demographic information is self-reported by the mother, and some comes directly from the birth certificate. The source of the data can be found by hovering over the question mark by the indicator selection title and under the Question Wording sub-heading in the Data Notes section of the indicator report.

Two new dimensions are now available

  • Gestational age, which comes from the birth certificate and is categorized as early preterm (<32 weeks), preterm (32-36 weeks), normal term (37-41 weeks) and post term (42+ weeks).
  • Birthweight, which comes from the birth certificate and is categorized as low (<2,500 grams), normal (2,500-3,999 grams), or high (4,000+ grams).

2015 PRAMS

The primiparous dimension is not available in 2015 due to irregularities with the underlying data.

2014 PRAMS

Mother's education level - this dimension comes from the birth certificate form. In 2014, the State of Hawaii transitioned to a new birth certificate form and this transition resulted in irregularities in this data field. Accordingly, mother's education will be suppressed from 2014 forward pending consultation with the Office of Health Status Monitoring at the Hawaii Department of Health.

All Years

Race/Ethnicity Data

The birth certificate allows for up to 4 race/ethnicities to be captured for both the mother and the father. The DOH Office of Health Status Monitoring (OHSM) uses the following algorithm to code a single race/ethnicity for each individual. Ethnicity of the child is based on the ethnicity of the father. It is based on the ethnicity of the mother when the ethnicity of the father is unknown.

Only one ethnicity is coded from the actual certificates. If more than one ethnicity is listed on the certificate, the following rules apply:
    1. If Hawaiian is one of the multiple ethnicities listed, Part-Hawaiian is coded.
    2. If a non-Caucasian ethnicity is listed with a Caucasian ethnicity, the non-Caucasian ethnicity is coded.
    3. If there is more than one non-Caucasian ethnicity listed, the first one is coded.
    4. If there is more than one Caucasian ethnicity listed, the first one is coded.

In IBIS, the most granular level is the program race/ethnicity (PRG) which rolls up into the DOH standard race/ethnicity (DOH), which rolls up into Census race reporting categories (Census). The table below illustrates how the data is aggregated.

Race/Ethnicity Classifications

Other Information

Note about indicator/dimension changes:

The PRAMS is constantly changing. HHDW staff carefully review the PRAMS survey instrument each year to assess how changes in the survey instrument impact indicators and dimensions within the Hawaii-IBIS system. If you have questions, check the Question Wording in the Data Notes section of the report.
