Michigan Contraceptive Access, Research, and Evaluation Study Children: Phase 1 (M-CARES-K)

May 30, 2026 updated by: Martha Bailey, University of Michigan

The Effects of Unintended Pregnancy on Children

This project builds on the Michigan Contraceptive Access Research and Evaluation Study (M-CARES) to evaluate the long-term effects of mothers' access to free contraceptives and reductions in unintended pregnancies on their children's well-being.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

M-CARES uses a randomized control trial design to assess the effects of providing free contraception to mothers on their children born before the intervention. The population subject to intervention is fecund women age 18-35 years at risk of pregnancy and who are clients at Planned Parenthood clinics of Michigan (PPMI), who meet income eligibility criteria, and who would otherwise pay out-of-pocket for services on the day of recruitment (i.e., lacking insurance coverage for received service). The experimental (treatment) condition is a mother's receipt of a voucher providing access to no-cost contraception (up to the price of a name-brand intrauterine device) for 100 days. The control group of mothers receives no voucher. All enrolled women complete a two-part baseline survey and consent to be re-contacted for two follow-up interviews in outgoing years. They also complete a two-part baseline survey and consent to be re-contacted for two follow up interviews in outgoing years. In addition, mothers consent to linkages to their own and their children's administrative data from records held by state and federal health, education, criminal justice, and tax records. Consent covers children already born to women at the time of intervention and children born after intervention. Survey and administrative data provide outcome measures to assess children's well-being and development up to age 18. The study will compare children of mothers who receive the intervention to those who did not.

Interventional

Enrollment (Estimated)

Enrollment

4700

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

1 second to 17 years (Child)

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

The proposed project will analyze the outcomes of children ages 0 to 17 years old whose mothers enrolled in the Michigan Contraceptive Access, Research and Evaluation Study (M-CARES). M-CARES participation requires that mothers are:

  • 18-35 years old
  • physically capable (biologically female and fecund) and at risk of having a pregnancy,
  • not pregnant at the time of enrollment
  • not wishing to become pregnant in the 12 months after enrollment,
  • are seeking care at Planned Parenthood of Michigan, and
  • face out-of-pocket costs for contraceptives at Planned Parenthood of Michigan.

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Experimental Group
Mothers randomized to receive a voucher to be used at Planned Parenthood to cover the cost of contraceptives
Behavioral: Mother receives voucher valued at 100% of cost of name-brand IUD (March 4, 2019-March 31, 2023)
M-CARES randomized vouchers for contraception valued up to 100% of inserting a name-brand IUD (e.g., Skyla, Paraguard, Mirena) for women with out of pocket costs at Planned Parenthood. This intervention occurred from March 4, 2019, forward.
Behavioral: Mother receives voucher valued at 50% of cost of name-brand IUD (August 26, 2018-March 3, 2019)
M-CARES randomized vouchers for contraception valued up to 50% of inserting a name-brand IUD (e.g., Skyla, Paraguard, Mirena) for women with out of pocket costs at Planned Parenthood. This intervention occurred after November 4, 2019.
No Intervention: Control Group
Mothers randomized to NOT receive a voucher. Mothers in this arm receive the Planned Parenthood standard of care priced according to the Planned Parenthood sliding scale.
