a The follow-up questionnaire asked participants who were not already breastfeeding at the time they enrolled in the biomonitoring study to describe whether they were "planning to breastfeed", "very likely to breastfeed", or "considering breastfeeding." The original GB-PBDE questionnaire did not make this distinction; biomonitoring participants were described as either currently breastfeeding or planning to breastfeed. |
