NCT06631950 | Recruiting

• 1 other identifier: BIOSFER RCT - 101071773
• Study Type: interventional
• Target: 10,000
• Locations: 2 countries
• Sites: 2

Brief Summary

This RCT investigates the impact of an educational video on fecundity knowledge among young adults. The video discusses several risk factors associated with fecundity, such as age and smoking. The primary outcome measure of the RCT is fecundity knowledge. The knowledge level is defined based on the following factors: Age; smoking; sexually transmitted infections; Success of spontaneous pregnancy according to female age; Success of pregnancy according to female age and fertility treatment. The secondary outcomes are: intentions regarding the timing of desired pregnancy/childbirth; fecundity-protective behaviors; life goals; realized fertility later in life.

Conditions

The Focus is to Investigate Effect of an Educational Video on Fecundity Knowledge Among Young Adults

Keywords

Fecundity knowledge; Fertility awareness; Family intentions; Video intervention

Outcome Measures

Primary Outcomes (1)

• Change in fecundity knowledge

  Fecundity knowledge level in intervention arm versus control arm. Fecundity knowledge is measured with validated self-reported questionnaire items; revised Cardiff Fertility Knowledge Scale. The values range from 1-100, higher scores indicate higher knowledge level. The knowledge level is defined as change in knowledge level of the following factors: * Age, smoking, STI (Chlamydia) * Success of spontaneous pregnancy according to female age * Success of pregnancy according to female age and fertility treatment

  Measured immediately after intervention (educational video), and at a later point of time (likely within 1-2 years) depending on the data collection logistics for the two cohorts

Secondary Outcomes (7)

• Change in intentions regarding timing of pregnancy/childbirth

  Measured immediately after intervention (educational video), and at a later point of time (likely within 1-2 years) depending on the data collection logistics for the two cohorts

• Change in life goals

  Measured immediately after intervention (educational video), and at a later point of time (likely within 1-2 years) depending on the data collection logistics for the two cohorts

• Change in adopting fecundity-protective behaviors

  Measured immediately after intervention (educational video), and at a later point of time (likely within 1-2 years) depending on the data collection logistics for the two cohorts

• Change in realized fertility (followed up in registers)

  3, 5, 10 years and 20 years follow-up in national birth registers' after the intervention.

• Change in realized fertility (followed up in registers)

  3, 5, 10 years and 20 years follow-up in national birth registers' after the intervention.

Study Arms (2)

Fecundity knowledge intervention

EXPERIMENTAL

In the experimental arm, participants receive a short (3 minutes) educational video on risk factors of importance for fecundity.

Other: Educational intervention

Control

NO INTERVENTION

In the no-intervention arm, the participants do not receive the intervention (a short educational video).

Interventions

Educational intervention OTHER

The educational intervention group will be provided with information that should allow them to correctly answer questions on fecundity knowledge and fecundity risks factors. The fecundity information will be provided through a short animated educational video (3 minutes) that will be sent out digitally. The control group is not receiving such information.
