Surveys

This survey is the first wave of the Elfe study. It was carried out by trained midwifes shortly after birth in the selected maternity wards. The survey is composed by a face-to-face questionnaire with the child’s mother, data extracted from medical records and two self-administered questionnaires (mother / father). The main objective is to obtain information about the pregnancy development and the socio-demographic context of the household.

This survey is the first step follow up survey. It was carried out by trained interviewers two months after the child’s birth through a telephone interview. The survey is formed by a mother questionnaire and a father questionnaire, which have as objective the setting of the household’s socio-demographic situation and the baby’s first development elements.

This survey covers the feeding habits of the child within his first life months. Parents could fulfil this self-administered questionnaire by electronic or paper interview.

This survey continues the tracing of the Elfe’s child about 1 year after his/her birth. It was carried out by trained interviewers through a telephone interview. The survey is also formed by a mother’s questionnaire and a father’s questionnaire, with the objective to set the main household’s socio-demographic changes, the child development and the first tracks of his/her social and cultural environment.

This database includes indicatory variables regarding the socio-economic context of the household’s region in 2011.
