AB Background: MOBI-Kids is a 14-country case–control studydesigned to investigate the potential effects of electromagnetic fieldexposure from mobile telecommunications devices on brain tumorrisk in children and young adults conducted from 2010 to 2016.This work describes differences in cellular telephone use and personalcharacteristics among interviewed participants and refusersresponding to a brief nonrespondent questionnaire. It also assessesthe potential impact of nonparticipation selection bias on studyfindings.Methods: We compared nonrespondent questionnaires completed by77 cases and 498 control refusers with responses from 683 interviewedcases and 1501 controls (suspected appendicitis patients) insix countries (France, Germany, Israel, Italy, Japan, and Spain). Wederived selection bias factors and estimated inverse probability ofselection weights for use in analysis of MOBI-Kids data.Results: The prevalence of ever-regular use was somewhat higheramong interviewed participants than nonrespondent questionnairerespondents 10–14 years of age (68% vs. 62% controls, 63% vs.48% cases); in those 20–24 years, the prevalence was ≥97%. Interviewedcontrols and cases in the 15- to 19- and 20- to 24-year-old agegroups were more likely to have a time since start of use of 5+ years.Selection bias factors generally indicated a small underestimation incellular telephone odds ratios (ORs) ranging from 0.96 to 0.97 forever-regular use and 0.92 to 0.94 for time since start of use (5+ years),but varied in alternative hypothetical scenarios considered.Conclusions: Although limited by small numbers of nonrespondentquestionnaire respondents, findings generally indicated asmall underestimation in cellular telephone ORs due to selectivenonparticipation.
