5Executive summaryZambiahasseenremarkable improvement inchildhoodsur-vivaloverthepasttwodecades.Whilethescale-upofmalariacontrol interventionshasbeenproposedasoneof thebig-gestdriversbehindthatimprovement,littleresearchhasbeendoneonhowmuchof the reduction in childhoodmortalitymaybeattributedtomalariacontrolandhowmuchisthere-sult of improvements inother childhealth interventions.Toaddressthisknowledgegap,theUniversityofZambia(UNZA)and the Institute for Health Metrics and Evaluation (IHME)worked together on theMalaria Control Policy Assessment(MCPA) project. The goal ofMCPAwas to harness existingdatainZambiaanduserigorousstatisticalmethodstoquan-tify the impact of malaria control and other child healthinterventionsonunder-5mortalitytrendsacrossdistricts.
Wefoundthatbetween1990and2010,acombinationofrapidlyscaledupchildhealthinterventionscontributedtoanadditional11%ofdeclinesinunder-5mortalityacrossZambia.We lookedat thecombinedeffectof these interventionsbe-cause the scale-up in ownership of insecticide-treated nets(ITNs)anduseofindoorresidualspraying(IRS)coincidedwiththescale-upinthreeotherkeychildhealthinterventions:thepentavalentvaccine,exclusivebreastfeeding,andservicestohelppreventmother-to-child transmissionofHIV (PMTCT)athealthfacilities.Isolatingthespecificimpactofeachinterven-tion isnotpossible.Nevertheless, jointly, these interventionscontributedsignificantlytothereductionofunder-5mortalitythroughoutthecountry.
TheMCPAprojectinZambiaproduceddistrict-leveltrendsforkeychildhealthoutcomesandinterventionsfrom1990to2010.This is thefirst time thatannualestimates forunder-5mortalityandinterventioncoveragehavebeengeneratedatthedistrict level. In this report,districtprofilesdetail trendsin child health over time and benchmark the districts per-formance across indicators.With this information, local andnationalpolicymakersandhealthofficials can identify areasofsuccessfulhealthservicedeliveryanddetectearlysignsofdeclininginterventioncoverageorstalledprogress.
This report shows that Zambia is succeeding on severalfrontsinchildhealth.First,countrywidereductionsinunder-5mortalitywerealsoaccompaniedbyimprovementsinequity
acrossdistricts,assomeofthedistrictswiththehighestmor-talityratesin1990recordedsomeofthegreatestdeclinesby2010.Second,coverageofkeymalariacontrolinterventions,such as ITN ownership, increased dramatically inmany dis-tricts.Third,themajorityofdistrictsweresuccessfulinquicklyincreasing coverage of the pentavalent vaccine after its in-troduction in 2005. Finally, rates of exclusive breastfeedingmarkedly rose in most districts, reflecting the countrys in-vestments in improving child nutrition and breastfeedingpractices(WBTi2008).
ThesesuccesseswereaccompaniedbyconcerningtrendsforthreekeychildhealthinterventionsinZambia.First,mostdistrictssawadeclineinthe2000sinantenatalcare(ANC4),which is theproportionofpregnantwomen15 to49 yearsold who had four or more visits to a health facility duringpregnancy. This finding is particularlyworrisomegiven thatdistrictsgenerallyincreasedlevelsofANC4duringthe1990s.Second, coverage of polio immunization dropped in someof thedistricts that are consideredathigh risk forpolio im-portationfromneighboringcountries.Third,insomeareasofZambia, skilledbirthattendancedeclined tovery low levels.Targeting these areas for improvement shouldbe aprioritytoensurethatthecountrysachievementsinchildhealthcon-tinueintothepresentdecade.
Withafocusondistricts,findingsfromtheMCPAprojectin Zambia provide side-by-side comparisons of health per-formanceover time, geography, and intervention type.Thechild health landscape is remarkably heterogeneous acrossdistricts,highlightingtheneedforcontinuousandtimelyas-sessmentofdistrict-leveltrends.Withregularlycollectedandanalyzed district health information, policymakers can havetheevidencebasetomaketargeted,data-drivendecisionsforachievinggreaterandmoreequitablehealthgainsinZambia.
6IntroductionOver the past decade, Zambias child health and develop-ment landscape has been substantially reshaped by newprograms, interventions, and priorities, including extensivemalariacontrolprograms. Inorder to fullyunderstandwhathascontributedtoZambiasprogress inunder-5mortality, itisimportanttocomprehensivelyaccountforalleffortstoim-provechildhealth.
TheMCPAprojectinZambiahadtwomainobjectives:
1) Determine what proportion of the decline in all-causeunder-5 mortality in Zambia was attributable to thescale-upofmalariacontrolinterventions,whileaccountingfor a range of other key child health interventions andnon-healthfactors.
2) Assessthisimpactatthedistrictlevelbetween1990and2010.
Inordertoachievetheseobjectives,annualestimatesofdistrict-level trends from 1990 to 2010 were systematicallygenerated foreachof the72districts inZambiaandacrossa range of key child health outcomes and interventions.Detaileddescriptionsofthefindingsforeachdistrictarepre-sented in this report.District-leveldatacanbedownloadedfrom IHMEs Global Health Data Exchange: http://ghdx.healthmetricsandevaluation.org/.

8Main findings
Under-5 mortality declines observed across districts, accompanied by reductions in inequities Zambia made substantial progress in improving child sur-vivalbetween1990and2010.Atthenationallevel,all-causeunder-5 mortality decreased by 37%, from 174 deaths per1,000 livebirths in1990 (95%CI: 168, 181) to109 in2010(95%CI:104,116).Alldistrictssawreductionsintheirlevelsofunder-5mortalityduringthistime.Moreover,manyofthedistrictswith thehighest levelsofunder-5mortality in1990showedthegreatestdeclinesby2010.Figure1depictshowthe range in under-5mortality across districts has becomenarrower.
In 1990, levels of under-5 mortality spanned from 125deaths per 1,000 live births (95%CI: 97, 161) to 276 (95%CI:220,338)indifferentdistricts.Twentyyearslater,thisgapsubstantiallytightened,witharangeof83deathsper1,000livebirths(95%CI:60,113)to150(95%CI:109,203).Thedif-ferencebetweenthedistrictwiththehighestlevelofunder-5mortalityandthelowestwasmorethanhalvedfrom1990to2010 (dropping fromadifferenceof 151 to 67), illustratinghowZambiasprogressinreducingunder-5mortalitywasalsoassociatedwithdecreasedhealthinequitiesacrossdistricts.
Despitetheseimprovements,itisworthnotingthatsomedistricts and regionsdocumented lessprogress.Districts inNorthernprovincehadveryhigh levelsofunder-5mortalityin 1990, and though many recorded large declines, theirratesstillremainedamongthehighestinthecountryin2010(greater than 120 deaths per 1,000 live births). Additionalefforts toreduceunder-5mortalityneedtobeprioritized inthesedistricts.
Malaria interventions are rapidly scaled up in Zambia, but most districts fall short of national targetsCoverageofmalariainterventionsgreatlyincreasedthrough-
outZambiaafter2000,withmostofthegainsoccurringsince2005. Nationally, the proportion of households that eitherownedatleastoneITNorreceivedIRSincreasedfrom8%in2000to37%in2005andthenrapidlyclimbedto71%in2010.Coverage of intermittent preventive therapy in pregnancy(IPTp2)quicklyrosefrom16%in2002toaround70%in2008.
In theearly2000s, coverageofmalaria control interven-tionswasverylowthroughoutZambia,withonlyafewdistrictsbenefitingfromITNpilotprogramsandearlyimplementationofIRS.By2010,however,alldistrictshadcoveragelevelsex-ceeding55%forhavingeitherITNsorIRS.Figure2showstheriseincoverageofmalariacontrolfrom2000to2010.

In 2010, polio immunization coverage reached 81% atthe national level. However, coverage varied greatly acrossdistricts,rangingfrom24%(95%CI:10%,42%)to99%(95%CI:98%,100%).Zambiaspolio-freecertificationwasacceptedin2005,but severaldistricts thatborder theDemocraticRe-public of Congo (DRC) andAngola are considered at highrisk forpolio importation from thesecountries (WHO2011).Someofthesehigh-riskdistrictsrecordeddecliningcoverageofpolioimmunizationduringthe2000sandhadsomeofthelowest levelsofcoverage inZambia in2010. IfZambia is tooptimallyprotectitselffromimportedpolio,deliberateeffortsare needed to ensure that levels of polio immunization aresustainedathighlevelsinhigh-riskareas.

Rapid scale-up of key child health interventions contributes to declines in under-5 mortalityToassess the impactofmalariacontrolonunder-5mortalityin Zambia, theMCPA research team conducted a causal at-tribution analysis that included a full range of child healthinterventions and non-health factors. More details on themethodsandstatisticalmodelsusedcanbefoundinAnnex1.
The teamfoundthatZambiahadscaledupseveral inter-ventionsat thesametime.Figure5showshowgains in ITNand IRS coverage coincided with rising levels of the pen-tavalentvaccine,exclusivebreastfeeding,andtheavailabilityof PMTCT in health facilities. It was statistically impossibleto teaseout the individual effects of these interventionsonunder-5mortality. Instead, researchers created a compositeindicatorofrapidlyscaledupinterventions.
Figure 5. The scale-up of malaria control interventions and a subset of key child health interventions
After accounting for other factors (including socioeco- nomic indicators), rapidly scaled up interventions were sig- nificantly associated with Zambias reductions in all-causeunder-5mortality. Ifthecoverageoftheseinterventionshadremainedatlevelsobservedin2000,under-5mortalitywouldhave been 11% higher in 2010 (124 deaths per 1,000 livebirths(95%CI:118,129))thanwhatwasactuallyobservedforthatyear(109deathsper1,000livebirths(95%CI:104,116))(Figure6).

Between 1990 and 2010, the health landscape in Zambiamarkedlychanged,and for themostpart, thesechangesre-flect progress and service delivery success throughout thecountry.Under-5mortalitysubstantiallydecreasedat thena-tionallevel,andthegapbetweendistrictswiththehighestandlowest under-5 mortality substantially decreased. These de-clinesinunder-5mortalitycanbetiedtoZambiassuccessfulefforts in expanding coverage for a subset of child healthinterventions:ITNownership,IRS,thepentavalentvaccine,ex-clusivebreastfeeding,andtheavailabilityofPMTCTservices.These five interventions were rapidly scaled up during the2000sandjointlycontributedtoanadditional11%reductioninall-causeunder-5mortalityinZambiabeyondwhatwouldhavebeenexpectedbasedonthecountrystrendsinunder-5mortality during the 1990s. The scale-up ofmalaria controlhas been a key part of Zambias improved health serviceenvironment, and sustaining high levels of malaria controlinterventions, alongsideother life-saving interventions, is ofcriticalimportance.

Intotal,20householdsurveys,onehealthfacilitycensus,threepopulationcensuses,and two administrative sources (National Malaria ControlCentreindoorresidualsprayingdatabaseandfacilityPMTCTservicesfromtheNationalAIDSCouncil)wereincludedinthefinalanalysis.
(2) Estimating trends for 72 districts from 1990 to 2010. GiventherangeofdatatypesassembledfortheMCPAproject,statisticalmodelingapproacheshad tobeused inorder tosynthesizetheestimatesfromthesedifferentdatasourcesintoaunifiedtrend.Demographicmethodsforanalyzingbirthhis-torydatawerecombinedwithsmallareaestimationmodelingtogeneratedistrict-leveltrendsforall-causeunder-5mortality.Atwo-stepmethodinvolvingspatio-temporalsmoothingandGaussianProcessRegression(GPR)wasusedtoproducedis-trict-level trends for intervention coverage and non-healthindicators.
(3) Conducting causal attribution analyses. Many models and combinations of covariates were rigorously tested inorder to identify the most robust and valid model for as-sessing the relationship between declines in mortality andindividual health interventions and non-health indicators.Thetypesofmodelsthatwereexploredincludedsingle-andmultistage linearmodels, lasso, functionaldataanalysis,firstdifferences, differences-in-differences, structural equationsmodeling,andfactoranalysis.Themodelthatwasultimatelyselectedisalinearmodelwithbootstrapping,asitbetterac-countsforautocorrelationoveryearsanddistricts.Thelistofcovariatesthatwereexploredincludedrainfalllevels,fertility,birthspacing,maternaleducation,schoolattendanceamongteenagers,femaleheadshipofhouseholds,meanhouseholdsize, household sanitation, prevalence of improved sourcesofcookingfuel,prevalenceof improvedwall type inhomes,electricity, immunization coverage, and coverageofmalariaandmaternalandchildhealthinterventionsdescribedinthe
main text of this report. Covariates that were not includedbecauseof lackofdata availability include coverageofma-lariatreatmentforchildrenwithfever,coverageofantibiotictreatment for childrenwithpneumonia, coverageof oral re-hydration treatment for children with diarrhea, coverage ofpediatricHIV treatment,qualityofdistrict healthofficeman-agement, district health expenditures and health personnel,accesstohealthfacilities,malariatransmission intensityovertimeandbydistrict,andnutritionalinterventions.
The MCPA research team found that it was statisticallyimpossible to tease out the impact of malaria control in-terventions from other interventions that also experiencedlargegains incoverageduring the2000s. Instead,principalcomponentanalysis(PCA)wasusedtobundletheserapidlyscaled-up interventionsmalaria control, exclusive breast-feeding,facilitiesofferingPMTCTperpopulationunder1yearold, and coverage of the pentavalent vaccineinto a com-positeindicator.Thefinalmodelestimatesthejointeffectoftheseinterventionsonunder-5mortality: ln(q) = 0 + 1Scaled + 2SES + 3Und + 4SES * Scaled + 5SES * Und + 6ANC1 + 7DPT3 + 8Meas + 9Year + k[ ] +

CHILD HEALTH OUTCOMES
SUMMARYChibombosubstantially reducedall-causeunder-5mortalitybetween1990and2010,bringingitsmortalitylevelsamongthe lowest in Zambia. Childhood underweight, however, in-creasedduringthe1990sbeforedeclining.Prioritizingwaysto further accelerate gains for child health outcomes, espe-ciallyunderweight,shouldbeconsidered.
Several interventions, including IPTp2, the pentavalentvaccine, and exclusive breastfeeding, were scaled up toor above the national averageby 2010.After slight dips incoverage,BCGandmeaslesimmunizationroseabovethena-tionalaveragesin2010.
However, amidst these gains, some worrisome trendswere identified and warrant further attention. Chibombosscale-up of ITNs and IRS laggedbehind the national trend,andpoliocoveragedeclinedinrecentyears.Skilledbirthat-tendance stayedquite low, and alarmingly,ANC4droppedsharplyfromhighlevelsofcoverageintheearly1990s.

SUMMARYBetween1990and2010,Kabwereduceditsall-causeunder-5mortality,buttherelativemagnitudeofthedistrictsprogresswasfairlylow.Whilechildhoodunderweightwascomparableto the national average, Kabwe made minimal progress inreducing prevalence. Prioritizing ways to further accelerategainsforchildhealthoutcomesshouldbeconsidered.
Kabwe increased IPTp2 coverage to well above the na-tional average in 2010, and IRS coverage was among thehighest inZambiathatyear.Thedistrictmadenotableprog-ress in increasingcoverageof thepentavalent vaccine,andhighlevelsofBCGandmeaslesimmunizationweresustainedduring the 2000s.

From 1990 to 2010, Kapiri-Mposhi recorded a reduction inall-causeunder-5mortality, dropping26% from151deathsper1,000livebirthsin1990(95%CI:118,193)to112in2010(95%CI:83,149);however, thisdeclinewasnotstatisticallysignificant.In2010,thedistrictsunder-5mortalitywasslightlyhigherthanthenationalaverageof109deathsper1,000livebirths(95%CI:104,116).
The proportion of children who were underweight in-creasedfrom9%in1990(95%CI:4%,18%)toahighof18%in1999(95%CI:15%,21%),butthendeclinedto9%in2009(95%CI: 7%,12%) and remainedat 9% through2010.Thislevel of underweight wasmuch lower than the national av-erageof14%in2010andamongthelowestinZambia.

The district successfully scaled up several interventions,rangingfromIPTp2to thepentavalentvaccine, tocoveragelevels equaling or exceeding the national average in 2010.High levels of measles coverage were maintained after in-creasesinthe1990s,andpoliocoveragerosetoamongthehighestinZambiain2010.
However,amidstthesesuccesses,sometroublingtrendswereidentifiedandwarrantfurtherattention.BCGcoveragefellbelow thenationalaverage in2010,and ITNownershipwas among the lowest levels in Zambia. The district expe-rienced substantial declines in ANC4 coverage and skilledbirthattendance.

This declinewas not statisticallysignificant.In2010,thedistrictsunder-5mortalitywasmuchhigherthanthenationalaverageof109deathsper1,000livebirths(95%CI:104,116).Thislackofprogressisworrisome
given that the districts levels of under-5mortality were farbelowthenationaltrendduringthe1990s.
The proportion of children who were underweight in-creasedfrom13%intheearly1990sto17%in1998(95%CI:13%,21%),and remainedat this level through2002.Under-weightthendeclinedto14%inthelate2000s,equalingthenational average for 2010.Overall, thedistrict showedmar-ginalprogressinreducingchildhoodunderweight.
