Thus, we could suppose that the main reasons for non-response included the respondent was not at home for the interview; she/he had a health condition that prevented her/him from answering it; and/or another adult answered the questionnaire on his/her behalf.
Por lo tanto, se podría decir que las principales causas de no contestar eran no estar presente en el hogar, presentar problemas de salud y/o que otro adulto haya contestado la encuesta.
