MICH-11.4 Increase abstinence from illicit drugs among pregnant women

About the Data

Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.

Data Source: 
National Survey on Drug Use and Health
Changed Since the Healthy People 2020 Launch: 
Baseline (Year): 
94.5 (2015–16)
Target-Setting Method: 
Total coverage
Target-Setting Method Justification: 
The importance of getting all women to abstain from using illicit drugs during pregnancy warrants this proposed target.

Number of pregnant females aged 15 to 44 years reporting not using any illicit drugs in the past month (30 days)


Number of pregnant females aged 15 to 44 years

Comparable Healthy People 2010 Objective: 
Retained from HP2010 objective
Questions Used to Obtain the National Baseline Data: 

    From the 2015 National Survey on Drug Use and Health:

    • Heroin______
    • Hallucinogens______
    • Inhalants______

    [The following questions are asked separately for nonmedical use of analgesics (prescription pain killers), tranquilizers, stimulants, and sedatives:]

    How long has it been since you last used (a pain killer, tranquilizers, stimulants, sedatives) that was not prescribed for you, or that you took only for the experience or feeling it caused?

Data Collection Frequency: 
Methodology Notes: 

    Illicit drugs are defined as marijuana or hashish, cocaine (including crack), inhalants, hallucinogens (including PCP and LSD), heroin, and nonmedical use of psychotherapeutics. To ensure adequate precision of estimates for pregnant women, estimates are based on combined data from two years.

    In 2014 and 2015 changes were made to the National Survey on Drug Use and Health (NSDUH) resulting in the need to revise the baselines and targets for 20 HP2020 objectives. In 2014, the changes to NSDUH primarily focused on revising the sample design, such as modifying the distribution of the sample across the 50 states and the District of Columbia and reducing the oversampling of youths and young adults. In 2015, SAMHSA implemented changes to the NSDUH data collection equipment, respondent materials, and survey questionnaire, including revisions to existing measures (e.g., prescription drugs, methamphetamine, hallucinogens, inhalants, and binge alcohol) and the addition of new questions (e.g., sexual orientation and attraction, disability status, and identification of active duty family members).

    The 2014 changes to the sample design are expected to result in more precise national estimates overall as well as more precise estimates for older adults. The 2015 changes are expected to improve the quality of data, and the questionnaire revisions will address SAMHSA's substance use and mental health policy and research needs.

    The following report outlines all of the changes that were made to the NSDUH in 2014 and 2015.

Revision History

Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.

Description of Changes Since the Healthy People 2020 Launch: 
The baseline for this objective was revised in 2019 due to a change in the methodology used to track this measure. The baseline year was revised from 2007-08 to 2015-16. The baseline was revised from 94.8% to 94.5%. In keeping with the original target setting method (total coverage), the target remained 100%.
