Note that for anthropometry a different procedure is used and age in days is calculated as part of the creation of the anthropometric indices, but this is restricted to living children under the age of 5 that were reported as living in the household. For most analyses, this difference has very little effect, but for a few, it can matter. Similarly, a birth in May 2016 would be considered as 12 months (1 year) old in May 2017, but if the birth is on May 3, 2016, and the interview on May 3, 2017, then the child is 11 months (0 years) old. Thus, if the day of birth is greater than the day of interview (roughly half of all cases) then the age would be over-estimated by one month. For example, a child born February 2017 was considered as 3 months old in May 2017, however, if the birth took place on February 25, 2017, and the interview was May 3, 2017, then the child is actually only two completed months old. Calculating age in months using just month and year of birth and month and year of interview meant that age in months could be off by one month in approximately half of all cases. Why was day of birth added for children in DHS-7?Īdding day of birth permits calculating the age of children more accurately. Additionally, it may also have been reported by a different respondent than the mother of the child. Note that while DHS had previously collected day of birth for children weighed and measured, these data were not used in conjunction with the birth history data as they were not available for a) children who had died, b) children of the respondent who did not live in the household, c) older children, and d) children for whom height and weight was not collected if it was only collected in a subsample of the households. Beginning with the DHS-7 questionnaires, (surveys with fieldwork in about 2015 and later), the woman’s questionnaire collects the day of birth for all children listed in the birth history (all children of the respondents to the woman’s questionnaire) in addition to their month and year of birth. As part of the biomarker data collection, day of birth was also collected for children age 0-5 years and was used in the calculation of the anthropometric indices.
