Brief Summary

This proposed study is to test whether Health Check-up for Expectant Moms (HCEM), a computer-delivered screening and brief intervention (SBI) that simultaneously targets sexually transmitted infection (STI) risk and alcohol/drug use during pregnancy, reduces antenatal and postpartum risk more than an attention, time, and information matched control condition among pregnant women seeking prenatal care.

Primary Outcome Measures
NameTimeMethod
Unprotected Sexual Occasions (USOs)Up to 6 months

USOs were instances of sexual intercourse where neither partner utilized any form of contraception. Participants were assessed using Timeline Follow-Back (TLFB), a calendar assisted structured interview that provided a way to cue memory so that accurate recall was enhanced for event-level data. TLFB has been used to assess sexual risk-taking. Participants were asked to provide the number of USOs experienced 90 days prior to baseline assessment, between baseline assessment and 2-month follow up, and from 2-month follow up to 6-month follow up.

Alcohol Use Measured by Timeline Follow-Back (TLFB)Up to 6 months

Alcohol use was measured by the TLFB. Participants were asked if they had consumed any standard alcoholic drinks 90 days prior to baseline assessment, between baseline assessment and 2-month follow up, and from 2-month follow up to 6-month follow up. Participants' responses could only be Yes or No. Results reflect the participants who responded Yes.

Cannabis Use Measured by Timeline Follow-Back (TLFB)Up to 6 months

Cannabis use was measured by the TLFB. Participants were asked if they had used or consumed any cannabis 90 days prior to baseline assessment, between baseline assessment and 2-month follow up, and from 2-month follow up to 6-month follow up. Participants' responses could only be Yes or No. Results reflect the participants who responded Yes.

Secondary Outcome Measures
NameTimeMethod
Heavy Episodic Drinking6 weeks postpartum (up to 11 months)

Heavy episodic drinking was defined as consumption of 4 or more standard alcoholic drinks during a single day. Participants were asked if they had engaged in any heavy episodic drinking 90 days prior to baseline assessment and from the period from birth to 6 weeks postpartum. Participants' responses could only be Yes or No. Results reflect the participants who responded Yes.

Sexually Transmitted Infections (STIs)Baseline to 6 weeks postpartum (up to 11 months)

STIs were measured using urine samples or home vaginal swabs testing kits, which were collected at the baseline assessment and 6 weeks postpartum. Results reflect participants whose results came back with positive results for any STI.

Unprotected Sexual Occasions (USOs) Postpartum6 weeks postpartum (up to 11 months)

USOs were instances of sexual intercourse where neither partner utilized any form of contraception. Participants were assessed using Timeline Follow-Back (TLFB), a calendar assisted structured interview that provided a way to cue memory so that accurate recall was enhanced for event-level data. TLFB has been used to assess sexual risk-taking. Participants were asked to provide the number of USOs experienced from the period of birth up to 6 weeks postpartum.

Birth Weight of Baby6 weeks postpartum (up to 11 months)

Birth weight of participants' babies was measured in grams.

Baby Head Circumference6 weeks postpartum (up to 11 months)

Head circumference of participants' babies was measured in centimeters.

Baby Birth Length6 weeks postpartum (up to 11 months)

Birth length of participants' babies was measured in centimeters.

Estimated Cost-effectiveness of Health Check-up for Expectant Moms (HCEM)6 weeks post-partum (up to 11 months)

Cost-effectiveness was measured in US dollars (USD) and was evaluated as the incremental cost-effectiveness ratio (ICER) that considers the difference in the mean total costs and the difference in health outcomes and events between the two arms. Results reflect the cost-effectiveness evaluation based on estimated costs per case of unprotected sexual occasion averted, alcohol or illicit drug use averted, and sexually transmitted infection (STI) event averted. To develop a plausible full range, a 25% variation of the estimated mean in each arm was used. All participants who were randomized were included in the analysis for this outcome measure.
