Dear DHS Forum,
I calculated stillbirth, earlyneonatal and perinatal mortality for the 2015-2016 Malawi DHS data using the below codes. However, I am unable to have the exact numbers of stillbirths, earlyneonatal and perinatal mortality. I wrote to the forum several times for help but no answer. I really need your kind responses and support is highly solicited
gen stillbirths = 0
label variable stillbirths "Stillbirths"
* Births in calendar
gen births = 0
gen births2 = 0
label variable births2 "Births in birth history (including twins)"
* Early neonatal deaths in the five years preceding the survey
gen earlyneo = 0
label variable earlyneo "Early neonatal deaths"
gen beg = v018
gen end = v018+59
local vcal_len = strlen(vcal_1[1])
forvalues i = 1/`vcal_len' {
replace births = births+1 if inrange(`i',beg,end) & substr(vcal_1,`i',1) == "B"
replace stillbirths = stillbirths+1 if inrange(`i',beg,end) & substr(vcal_1,`i',7) == "TPPPPPP"
}
replace end = v008
replace beg = v008-59
rename b3_0* b3_*
rename b6_0* b6_*
forvalues i = 1/20 {
replace births2 = births2+1 if inrange(b3_`i',beg,end)
replace earlyneo = earlyneo+1 if inrange(b3_`i',beg,end) & inrange(b6_`i',100,106)
}
gen totpreg7m = births2+stillbirths
label variable totpreg7m "Number of pregnancies of 7+ months duration"
* total perinatal mortality = early neonatal deaths plus stillbirths
gen perinatal = earlyneo+stillbirths
label variable perinatal "Perinatal mortality"
gen wt = v005/1000000
svyset v021 [pweight=wt], strata(v023)
svy: tab v190 stillbirths, cell count
