Parents' knowledge and predictions about the age of menarche: experimental evidence from Honduras.

Background: Access to accurate, timely and age-appropriate information about menarche is an essential part of menstrual health. Reliable evidence shows that girls primarily obtain information from their mothers and/or other female family members, therefore, it is important to determine parents' knowledge and their predictions about other parents' knowledge of the age of menarche.

Methods: To this end, we performed a pre-registered study with data collected from 360 households in Santa Rosa de Copán, Honduras.

Binary responses consist of two possible opposing response options (Yes/No). Continuous responses are numerical, where respondents can indicate an option on a 0-10 horizontal blind line.
