About this study

Crying is a survival mechanism for babies and their almost exclusive means of expression until the age of 4 months. Babies 'cry is mostly related to pain, a feeling of hunger, discomfort or separation following the departure of a parent around. Crying is a complex but essential means of communication and information between a baby and his parents that raises the question of their meaning.

Very few longitudinal studies have been produced on preterm's crying. As the term approaches, the characteristics of preterm babies' crying are similar to those of term infants. But these studies date back more than 30 years and are obsolete in terms of the quality and performance of sound recording equipment and signal processing.

No study has looked at the genesis of the cry itself and the varieties of the cry of the preterm baby, depending on whether it was in a situation of hunger, pain, discomfort (bath).

Read the detailed description

This longitudinal study recordings of crying babies from 26 amenorrhea week to 33 amenorrhea week, 24 hours per week, each week until the return home. In the same time, parents will be asked to know the situation of the baby (hunger, pain, bath).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Analysis fundamental frequency (f0)

    Measured by PRAAT software for 24h every week

    Measured: at the end of hospitalization (on average 2 months)

Secondary outcomes (4)
  1. Analysis roughness of the cry (PC1)

    Measured by PRAAT software for 24h every week

    Measured: at the end of hospitalization (on average 2 months)

  2. Analysis pitch of the cry (PC2)

    Measured by PRAAT software for 24h every week

    Measured: at the end of hospitalization (on average 2 months)

  3. Analysis NIP∑ (neonatal index of parasympathetic activity) index

    Measured by monitor MDoloris® for 24h every week

    Measured: at the end of hospitalization (on average 2 months)

  4. Correlation between crying acoustic structures and parent's responses

    Measured by completed questionnaire by parents (Linear Mixed Model) every week

    Measured: at the end of hospitalization (on average 2 months)
