Furthermore, the validity of commonly used coverage indicators for iron\u2010containing supplement consumption is questionable. The WHO\u2013UNICEF Technical Expert Advisory Group on Nutrition Monitoring, and partners, have systematically worked to identify a feasible and valid indicator of iron\u2010containing supplement coverage for reporting by countries. In 2019, we conducted key informant interviews with respondents in eight countries, fielded an online survey (in three languages using SurveyMonkey) to which 142 nutrition professionals from 52 countries responded, and used Demographic and Health Surveys (DHS) data from four countries to assess determinants of the quality of iron\u2010containing supplement coverage data. Less than half (45%) of online survey respondents were satisfied with the current methods for collecting iron\u2010containing supplement coverage data in their context. Recommended changes by study respondents include recall period &lt;5 years, adding questions about counselling, including other beneficiary groups, and assessing supply chain functionality. The DHS analysis suggested an association between time since pregnancy and data quality. Data heaping on multiples of 30 was observed in 40%\u201375% of data. There is a clear demand for a revised indicator and measurement guidance for coverage of iron\u2010containing supplementation during pregnancy. Future research should continue the development and validation of a global indicator, to more precisely validate the quality of recall data, including the distinction between distribution and consumption using various question formulations.<\/jats:p>","DOI":"10.1111\/mcn.13314","type":"journal-article","created":{"date-parts":[[2022,1,29]],"date-time":"2022-01-29T07:49:24Z","timestamp":1643442564000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Critical assessment of the current indicator for antenatal iron\u2010containing supplementation coverage: Insights from a mixed\u2010methods study"],"prefix":"10.1111","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9148-843X","authenticated-orcid":false,"given":"Aatekah","family":"Owais","sequence":"first","affiliation":[{"name":"Nutrition International Ottawa Canada"},{"name":"Centre for Global Child Health, Research Institute Hospital for Sick Children Toronto Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1972-0150","authenticated-orcid":false,"given":"Sara","family":"Wuehler","sequence":"additional","affiliation":[{"name":"Nutrition International Ottawa Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rebecca","family":"Heidkamp","sequence":"additional","affiliation":[{"name":"International Health, Bloomberg School of Public Health Johns Hopkins University Baltimore Maryland USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vrinda","family":"Mehra","sequence":"additional","affiliation":[{"name":"Data and Analytics Section, Division of Data, Analysis, Planning and Monitoring UNICEF New York City New York USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lynnette M.","family":"Neufeld","sequence":"additional","affiliation":[{"name":"Global Alliance for Improved Nutrition (GAIN) Geneva Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lisa M.","family":"Rogers","sequence":"additional","affiliation":[{"name":"Department of Nutrition and Food Safety World Health Organization Geneva Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kuntal Kumar","family":"Saha","sequence":"additional","affiliation":[{"name":"Department of Nutrition and Food Safety World Health Organization Geneva Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,1,28]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1177\/0890334417691506"},{"key":"e_1_2_10_3_1","unstructured":"Canadian travel survey microdata user's guide.
