3.1ThefirstthousanddaysNHSChoices(PregnancyandBabyCare)(NHSChoices2016b)providesextensiveadviceonhealthandlifestylefactorsforpregnantwomenandmothersofinfantsandyoungchildrentohelpthemgivetheirchildthebeststartinlife–includinghealthydietsforpregnantwomen,theharmsmokingandalcoholcancausetheunbornbaby,andbreastfeeding.However,theimportanceofthefirstthousanddaysoflife,startingwithconception,isnotwidelyrecognised,despitetheincreasingbodyofresearchshowingthatearlydevelopment(theperiodfromconception–andthereforepreconception–toagetwo)isverysensitivetodisruptionbyenvironmentalinfluencesthataffecttheriskofdevelopingnon-communicablediseases(NCDs)inlaterlife(Wadhwaetal.2009;HansonandGluckman2014).ThisrelativelynewareaofresearchisknownasDOHaD(DevelopmentalOriginsofHealthandDisease)andthereisevidencethattheriskofdevelopingNCDsinlaterlifecanbepassedontofuturegenerationsthroughtheprocessofepigenetics.

‘Barker’shypothesis’emergedintheearly1980s‘fromepidemiologicalstudiesofbirthanddeathrecordsthatrevealedahighgeographiccorrelationbetweenratesofinfantmortalityandcertainclassesoflateradultdeathsaswellasanassociationbetweenbirthweightandratesofadultdeathfromischemicheartdisease’(Wadhwaetal.2009).TheseobservationsledtothetheorythatundernutritionduringpregnancyprogrammesthemetabolismofthedevelopingfoetusandthatthiscanleadtoanincreasedriskofdevelopingNCDsinlaterlife.Anumberofotherfactorscandisruptearlydevelopment,includingmaternalobesity,infantoverfeedingwithformulaproducts,pretermbirth,gestationaldiabetesandexposuretotobaccosmoke,toxinsandpollutantssuchasheavymetalsandairbornemicroparticles(HansonandGluckman2014).Exposuretoharmfulenvironmentalfactorscanaffectdevelopmentofvitalorgans(includingtheheartandbrain)andtheprogrammingofbiochemicalandphysiologicalprocesses(forexample,theimmunesystemandthesatietyresponse),whichhaveimpactsonhealththroughoutlaterlife.

TheimpactofairpollutionishighlightedinarecentreportfromtheRoyalCollegeofPhysiciansandtheRoyalCollegeofPaediatricsandChildHealth,EveryBreathWeTake:theLifelongImpactofAirPollution(RCP/RCPCH2016).Damagecanstartfromconceptionandparticularlyvulnerabletimesaregestation,

In2004,theInternationalSocietyforDevelopmentalOriginsofHealthandDiseasewassetuptopromotemultidisciplinaryresearchinthisarea.AwhitepaperpublishedinthejournalEnvironmentalHealth(Baroukietal.2012)concludedthattheDOHaDevidencewasrobustenoughtojustifyfutureinvestmentinresearchanddisease-preventionstrategiesthataretargetedattheperiodofearlylife,includinggestation.ArecentsupplementinReproductiveHealthwasdevotedtopreconceptioncareandhighlightstheimportanceofnutritionaladviceforwomenofchild-bearingage,particularlyadolescents(Deanetal.2014)andtheneedforbetterunderstandingofthepossibleadverseeffectsofsubstanceabuseonfuturepregnancies(Lassietal.2014).

Followingthis,theUK’sNationalChildbirthTrustprogramme,TheFirstThousandDays(NCT2016),wassetup;itseekstoeducateandsupportparentsfrompregnancythroughtoeducationofyoungchildren.NCTisalsocarryingoutamajorstudytofindoutwhatlifeislikefortoday’sparentsinthefirstthousanddays.

Thelinkbetweenearlydevelopmentandhealthinlaterlifehasledtotheargumentthat‘ifweactearlywecanpreventharm’(BertramandPascal2014).Thisreportstressedthatamixofuniversalandtargetedinterventionsisthebestwayforward.Thisisparticularlyimportantinthecaseofpreterminfants,whoaremoresusceptiblethanchildrenbornattermtoabnormalitiesthataffecttheirfuturehealthandwellbeing,suchasmotordevelopment,behaviourandschoolperformance(Moreiraetal.2014).

3.4.1.Diet,exerciseandobesity

TheWorldHealthOrganizationGlobalStrategyonDiet,PhysicalActivityandHealth,whichwasadoptedbytheWorldHealthAssemblyin2004,highlightschildhoodobesityasoneofthemostseriouspublic-healthchallengesofthe21stcenturybecauseoverweightandobesityinchildhoodarelikelytocontinueinadulthoodandleadtoanincreasedriskofdevelopingnon-communicableconditionssuchascardiovasculardiseaseanddiabetesatarelativelyyoungage(WHO2004).TheWHO’sCommissiononEndingChildhoodObesity(ECHO)reportedin2016,emphasisingthatmanychildrenaregrowingupinanobesogenicenvironmentthatresultsinenergyimbalancefromacombinationofahigh-energydiet(encouragedbytheaccessibilityandmarketingofhigh-caloriefoods)andasedentarylifestyle.Thereportconcludedthatnosingleinterventioncanhalttheriseofthegrowingobesityepidemicandthatthereneedtobeeffectivestrategiestoaddresstheobesogenicenvironment,bearinginmindtheeffectsatcriticalstagesinthelifecourse(i.e.preconception/pregnancy,infancy/earlyyearsandchildhood/adolescence)(WHO2016).

Riskfactorsforoverweight/obesityarepoordietandlackofexercise,andNHSChoicesprovidesextensiveadviceandrecommendationsforahealthydiet(NHSChoices2016b)andphysicalactivitylevels(NHSChoices2016a)forpregnantwomenandchildrenunderfive.Theimportanceofahealthydietinpregnancy–withplentyoffruitandvegetablesandavoidinganexcessofsugaryandhigh-fatfoods–ishighlighted,andthereisadviceontakingsupplementssuchasvitaminDandfolicacid.Thereisalsoinformationonbreastfeeding,expressingbreastmilkandbottlefeeding.

TheNHSrecommendsthatinfantsareexclusivelybreastfedforatleastsixmonthsandthenbreastfeedingiscontinuedforanothersixmonthswhileotherfoodsareintroduced.However,theresultsofaninternationalsurveyofbreastfeedingreportedinTheLancetfoundthatonly34percentofUKwomenbreastfeedforsixmonths,andonly0.5percentcontinuetobreastfeedfor12months(Victoraetal.2016).Thiscomparesbadlywithotherhigh-incomecountries–forexample,inNorway35percentofwomencontinuetobreastfeedfor12months,whileinlow-incomecountriessuchasIndiathefigureisover90percent.Theauthorsalsodescribedevidenceforthehealthbenefitsofbreastfeedingbothtothemother(itprotectsagainstbreastcancer,andpossiblyalsoovariancancer)andchild(itprotectsagainstinfectionandmayalsodecreasetheriskofobesityanddevelopingdiabetes).Theyconcludedbypointingoutthatprotection,promotionandsupportofbreastfeedingisdirectlyrelevanttoGoals2(improvenutrition)and3(ensurehealthylivesandpromotewellbeingforallatallages)oftheSustainableDevelopmentGoals(UN2015).
