1.Introduction
Smokingduringpregnancyis associatedwithadverse health outcomesforboththebaby,suchasanincreasedriskoflowbirth weight,fetalgrowthrestrictionandstillbirth,andforthemother, suchascardiovasculardiseaseandcancer[1,2].However,despite these health risks, some women continue to smoke during pregnancy. Withanestimatedprevalence ofaround8%, Europe hasthehighestprevalenceofsmokingduringpregnancycompared tootherregionsintheworld[3]. Womenfromlower socioeco-nomicgroups,womenwhoexperiencehigherlevelsofstress,and womenwithasmokingpartneraremorelikelytosmokeduring pregnancy[4,5].
Toencouragepregnantwomentoquitsmokingandtoremain abstinentpostpartum,healthcareprofessionalsprovidesmoking cessationsupport.Severalguidelinesrecommendthathealthcare professionalsprovidecounsellingforbehaviouralchanges[6–8], oftenbasedonstagesofanindividual’sreadinessforsuchchange [9].Ifneeded,behaviouralcounsellingcanbecombinedwithmore intensiveinterventions,likepharmacotherapyortelephone-based support [6–8]. Smoking cessation support has shown to be effectiveinincreasingtheproportionofwomenwhoquitsmoking duringpregnancy[10,11].
However,despiteitseffectiveness,onlyasmallpercentageof pregnant women make use of professional smoking cessation support: in the United Kingdom (UK) and in the Netherlands respectively12%and7%ofpregnantwomen[12,13].Reasonsfor this mightbethatsomehealthcareprofessionalsdonotdiscuss smoking behaviour or offer support because they lack the necessaryknowledgeandtrainingandareconfrontedwithtime restrictionsand women’slackof motivationtodiscusssmoking cessation [14,15]. On the other hand, some pregnant women perceive thatthey havemissedopportunities,as theywerenot informed about support options or have not received the information and support they preferred, and the support by professionalsdidnotfittheirneeds[16,17].
Tothebestofourknowledge,onlyafewstudiestodatehave investigated pregnant women’s needsfor professionalsmoking cessationsupport.Thesestudies,performedintheUK,Australia, andNewZealand,werefocusedmainlyonindigenousandsocially disadvantaged women [17–20]. Personalised support, easily accessibleinformation,andrespectfuldiscussionswithout judge-ment were identified as women’s needs when considering smoking cessation support [17–19]. In addition, the study that focusedonamoregeneralpopulationfoundthatpregnantwomen prefer to receive support from someone who has also had experiencewithsmoking[20].
Because of cross-country differences in smoking cultures, it cannot be said with certainty that these reported needs for professionalsmokingcessationsupportarethesameasthoseof pregnant women in the Netherlands. Compared to the Netherlands,theUKandAustraliahavehighlevelsofimplemented tobacco control policies (e.g. budget for public information campaignsandsmokingcessationservices)[21,22].Furthermore, in these countries the smoking cessation support services for pregnantwomendiffer.TheUKhandlesanopt-outreferralsystem forpregnantwomen,andoffersCarbonMonoxide(CO)testingas standard procedure[6].InAustraliaandNewZealand,pregnant womenarereferredtotelephone-basedcounselling(Quitline)for smoking cessation support [8,23], whereas in the Netherlands pregnantwomenareadvisedtoconsultaspecialisedhealthcare professionalformoreintensivesupport[7].
Studies performed to evaluate these smoking cessation programs generallyreport that theyareeffective byincreasing theproportionofpregnantwomenwhostopsmoking.IntheUK, the introductionoftheopt-out referral systemwithCO testing
has-, compared to the previous opt-in system, doubled the proportion of pregnant women who set a quit date and who actuallystoppedsmoking[24].Althoughnostudiesareavailable ontheuseoftheQuitlinebypregnantwomeninAustraliaandNew Zealand, telephone-based counselling in general seems to be effectivebyincreasingcessationrates[11].Astudyperformedin theNetherlandsreportedthatbehaviouralcounsellingprovidedby midwivesdoubledtheproportionofpregnantwomenwhostop smoking[25].However,only10%oftheDutchmidwivesactually providefullbehaviouralcounselling;morethan79%oftheDutch midwivesreferpregnantwomenformorespecialisedsupport[26]. Theaimofthisqualitativestudywastoinvestigatetheneedsof pregnantwomenandtheirpartnersinthenorthernNetherlands forprofessionalsmoking cessationsupport.Thefocusis onthe north of the Netherlands because of its high percentage of pregnant women who smoke [27]. Moreover, as the smoking behaviour of pregnant women is associated withthe smoking behaviourofpartners,theneedsofthelatterwillalsobetakeninto account[5].
2.Methods 2.1.Design
This qualitative study makes use of a phenomenological framework,aimedatunderstandingpeople’sexperienceswithin thecontextoftheirdailylife[28].Semi-structuredinterviewswere heldtogaininsightintotheneedforsmokingcessationsupport duringpregnancyonthepartofwomenandtheirpartnerslivingin the northern Netherlands [28]. In February 2020, at a Dutch conferencefortobaccocontrol,apeerdebriefingwasperformed. Thepurposeofapeerdebriefingistoestablishthereliabilityand trustworthinessofthedata[28]. Ontheconferencefortobacco control, we presented themethod and results of this study to researchersandhealthcareprofessionalsresponsiblefor support-ingsmokingcessation.Afterthepresentation,theinterpretationof theresultswasdiscussedwiththepeerresearchersandhealthcare professionals.Theresearchersandhealthcareprofessionalsatthe Dutchconferencefortobaccocontrolconfirmedtheresultsofthis paper.
2.2.Recruitmentofwomenandtheirpartners
Interviewswereconductedwithwomenandpartnerslivingin thenorthernprovincesoftheNetherlands,i.e.Groningen, Fries-landandDrenthe.Becausetheprevalenceofwomenwhosmokeis knowntoincreasepostpartum intheNetherlands[13],women who had recentlygiven birth werealsoinvolved in this study. Womenwereinvitedtoparticipateiftheywerepregnantandwere currentlysmoking,pregnantandhadquitsmokingatthestartofor duringtheirpregnancy,oriftheyhadgivenbirthwithinthelast yearandwerecurrentlysmoking.
Twoexpertsbyexperienceinpovertyandsocialexclusion,and tworesearchersfromanorganisationthatrepresentsthevoicesof consumersinresearch(inDutch:Zorgbelang),wereinvolvedinthe recruitmentofwomen.Aflyerwithinformationaboutthestudy and contactdetailsof thefirstauthor(SW)was distributed via Facebook groups targeting mothers in the north of the Netherlands,socialmediapagesoftheresearchers(i.e.LinkedIn and Facebook), the network of Zorgbelang, food banks, super-markets, baby stores, midwives, and obstetricians, and subse-quentlyvia women and theirpartners. We aimed toinclude a representativesampleofwomenandtheirpartnerswithdifferent socialbackgrounds,livinginthenorthoftheNetherlands.Women couldsignup fortheinterviewbycontactingSW viae-mailor telephone.

Thewomenandtheirpartnerswereinformedabouttheaimof theinterviewsbothinpersonandbyaninformationletter,after which they were asked to sign an informed consent form. Participationwasvoluntaryandwomenandtheirpartnerscould withdrawfromtheinterviewatanymoment.Fortakingpartinthe study,womenandtheirpartnersreceivedavoucherworths25. 2.3.Datacollection
Semi-structured interviewswere held from May 2019 until October2019.Theexpertsbyexperienceandtheresearchersfrom Zorgbelangwereinvolvedinthedevelopmentofasemi-structured interview guide, whereby special attention was paid to the phrasing of the questions. The main questionof interest was: “How would you like tobe supportedwith smoking cessation duringpregnancy?”Aftereachinterview,fieldnoteswerewritten downandtheinterviewguidewasevaluated.Noquestionswere addedtotheinterviewguide.
TheinterviewswereconductedinDutchbySW,eitheraloneor together with an expert by experience or a researcher from Zorgbelang.Allinterviewerswerefemaleandreceivedinterview trainingbeforehand.Atthestartoftheinterview,theinterviewers introducedthemselvestotheparticipant,tellingbrieflyabouttheir workandtheirinvolvementinthestudy.Theinterviewershadno relationship with the women and their partners before the interview. Theinterviewswereheldata locationof thewomen and theirpartners’choice,mostoftenat theirhomesor atthe UniversityMedicalCenterGroningen.Childrenofthewomenand theirpartnerswerepresentduringeleveninterviews.The inter-viewslastedonaverage39min(range18 66min).Theinterviews wereaudiorecordedwithpermissionfromthewomenandtheir partners.Amembercheckwasperformedbygivingwomenand theirpartnerstheoptiontoreadandcommentonthecompleted transcripts[28].Aftercompletionofthestudy,womenandtheir partnerswereinformedabouttheresults,butnoneofthemgave feedbackonthetranscriptsorresults.
2.4.Dataanalysis
Therecordingsoftheinterviewsweretranscribedverbatimand anonymised. Data management and coding was donewiththe software ATLAS.ti 8.4. Data collection and analysis took place concurrently.Thedatawasanalysedusingasix phasethematic approach [29]. First, SW (health scientist) read all transcripts multiple times to become familiar with the data. The second author (JCW – psychologist) also read seven transcripts. After becoming familiar with the data, SW and JCW discussed the transcriptswiththeaimtogenerateinitialcodes.Afterwards,SW appliedtheformulatedcodestothedata.Inthethirdphase,SW and JCWdiscussedthecodeswiththeaimtoidentifypotential patternsinthedata.Thecodeswerearrangedincategorieswhich

1 Understandingwomen’sneeds
Women and their partners expressed that apart from the complexityofanicotineaddiction,circumstancesintheirdailylife influencedtheirdecisiontocontinuesmokingduringpregnancy. Somewomenexperiencedseriouslife-eventsbefore andduring pregnancy,suchasunstablerelationships,financialstress,andloss offamilymembers.Forthesewomensmokingwasawayofcoping withthese life-events;they expressedthat theycouldconsider smokingcessationonlywhenthesestressorsweredealtwith.
In my case it’sto havesomething todo andaslittle stressas possible.Itactuallyhasabittodowithexternalcircumstances–. Yeah,withmeit’sjustatypicalviciouscircle.SoIknowwhyI smokeandso.(#16,pregnant,currentsmoker)
Womenwhoweremotivatedtostopsmokingpreferredthatthe healthcare professional continue to ask about their smoking behaviourandneedforsupportduringtheentirepregnancy.With allwomensmokingwasdiscussedduringthefirstvisit,butoften remainedunaddressedinsubsequentconsultations.Bothwomen who managedtoquitsmokingand thosewho didnot succeed, wouldhavepreferredtodiscusstheirsmokingbehaviourandneed for smoking cessation more often. The women who stopped smoking would have liked toshare theirstruggles and receive complimentsfromthehealthcareprofessional.
Shedidnotdiscussitanyfurther,like"areyoustrugglingwithit?". No, shejustasked "haveyoustopped(smoking)?".AndwhenI confirmed,thatwasthat.ThenIwasthinkingyes[..]'givemea compliment orsomething'. Butshe was like "okay,fine!". (#9, pregnant,quitsmoking)
Women who continued to struggle with smoking cessation would have preferred the healthcare professional to keep considering waysto stopsmoking. On theother hand,women whodidnotwanttostopsmokingexpressedthattheydidnot wantthehealthcare professionaltoaddress theissuein subse-quentvisits.Accordingtothewomen,healthcareprofessionalscan best discuss smoking cessation by asking open questions (e.g. ‘whatwouldbeareasonforyoutothinkaboutsmokingcessation?’ and‘howcanIsupportyouwithsmokingcessation?’).
Ithink, just asking whatsomeone needs, [...] more like if a midwifeasks'howcanIsupportyou?'Likethat.(#12,pregnant, quitsmoking)
Womenandtheirpartnershaddifferentpreferencesastothe kind of healthcare professional tosupport them withsmoking cessation:theirmidwife,generalpractitioner,apracticenurse,an addiction expert, or an expertby experience withsmoking. In general,womenandtheirpartnersemphasisedtheimportanceof someonewithpersonalknowledgeofnicotineaddiction,someone whounderstandstheirstruggle.Somewomenperceivedthattheir healthcare professional didnot really understand how difficult smokingcessationwasforthem.
Butthenyougetthatadvice,thereallystandardadvice.Likeohyes, youjusthavetogoon,andifyoufeeltheurgeyoushouldeata grapeordrinkaglassofwater.Ithinkthatisjustnouse.That’sjust thekindofadvicenon-smokersgive.(#26,pregnant,quitsmoking)
2Responsibilitywithoutcriticism
Themajorityof women andsomepartners highlightedhow important it was that the healthcare professional recognise a woman’sownresponsibilityin smokingcessation.Smokingand smoking cessationwere seen as individual decisions. Although womenwantedthehealthcareprofessionaltoshowinvolvement, somewomenandtheirpartnersexpressedthat theywantedto makethedecisiontoquitsmokingthemselves,andthereforedid notneedadditionalsupportfromahealthcareprofessional.
ButIwanttodoitmyself.I’mthebossovermyownbody;that’s howIseeit.[...]ThenIthink‘yes,I’mtheonewhostarted,Iknow there are lots of disadvantages to smoking, um, I’m a grown

Formostwomen,thehealthofthefetusandtheirwishtobea role modelfor theirchildrenwas theirmain motivationtoquit smoking.Tobeabletomakeanautonomous,informeddecision, women indicated that they would have liked to receive more tailored and visual information from healthcare professionals aboutthehealthdamageofsmokingforthemandfortheirfetus, forexampleinformationabouttheoxygenlevelintheirplacentaor theconditionoftheirownlungs.

In addition,womenwantedtoreceiveinformation aboutthe various methods for smoking cessation support (e.g. nicotine replacement therapy). A few women expressed a need for medication that can help with smoking cessation and can be takenduringpregnancy.
Since women and theirpartnersperceivedsmoking astheir ownresponsibility,theydidnotwanthealthcareprofessionalsto interfere with this. Therefore, healthcare professionals who criticisewomenforsmokingduringpregnancy,andwhoaddress theissueinajudgmentalway,evokeresistanceonthepartofthe women and their partners. The women and their partners expressed that they wantedtobevalued and respectedbythe healthcareprofessionals,whetherornottheystoppedsmoking.

But that they tried to do everythinginagreementwithme,alsogivinginformation.That wayyoudon’tfeelforced,youdon’tfeelasiftheschoolteacheris wavinghisfingeratyou.Thatwasverynice.(#21,recentlygave birth,smokedduringpregnancy)

Thewomenhadmanysmokersintheirsocialnetworks.Apart from their partners, most women had friends, family, and colleagues who also smoked. Being exposed to the smoking behaviourofotherscanbechallengingforthesewomen.Although mostwomendidnotexpecttheirpartnertostopsmokingduring theirpregnancies, they didexpressthat this would beof great supportforthem.

Furthermore, some women experienced great support from other pregnant women when dealing with smoking cessation. Theyexpressedthatthesewomenknewandunderstoodwhatthey weregoingthrough.Anumberofwomenreceivedgroupprenatal care, where they experienced professional support in a group wheresomeotherwomenhadalsostoppedsmoking.
4.Discussion
Although healthcare professionals offer smoking cessation supportforpregnantwomen,onlyfewwomenactuallymakeuse ofthissupport[12,13].Weaimedtogaininsightintotheneedsof pregnantwomen,andofwomenwhorecentlygavebirthandtheir partners in the north of the Netherlands with different social backgroundsinrelationtoprofessionalsmokingcessationsupport. We identified three main themes: 1) Understanding women’s needs,2)Responsibilitywithoutcriticism,and3)Womenandtheir socialnetwork.Theresultsindicatethatwomenneedsupportfrom anunderstandingandinvolvedhealthcareprofessionalwhotailors thesupporttotheirneeds;women’s experiencedstressors and motivation levels have implications for their support needs. Women want the healthcare professional to discuss smoking cessationinaneutralwayandtosupporttheminmakingtheir owndecisionaboutit.Womenalsovaluetheinvolvementoftheir socialnetworkintheprofessionalsupport.
Ourfirstresultsuggeststhatsomepregnantwomendowantto quitsmoking,butcannotbecauseofseriouslife-eventswhichthey haveexperiencedbeforeorduringpregnancy.Womenindicated thatitisdifficultforthemtobeopentosmokingcessationsupport ifthesestressorspersist.Thisresultisinlinewithotherstudies thatidentifiedstressasanimportantbarriertosmokingcessation [15,30].Thesestudiesconcludethatlearningtocopewithstressors shouldbepartofsmokingcessationprograms[15,30].However, althoughstressreductioninterventionsseemtobeeffectivefor reducingstresslevelsduringpregnancy[31],thepregnancyperiod may be too short and too intensive to deal adequately with stressors.Inlightoftheimportanceofsmokingcessationduring pregnancy, stressors should be made open to discussion and womentaughttocopewiththese,preferablyinanearlyphaseor evenbeforepregnancy.
Asecondresultisthattheneedsofwomenwhoaremotivated to stop smoking seem to differ from those of non-motivated women.Whilemotivatedwomenindicatedthattheyneed(more) supportfromaninvolvedhealthcareprofessional,non-motivated womenseemedtopreferlessinvolvement.Thisresultillustrates thatwomen needsupportthat istailoredtotheirown levelof readiness to quit smoking [9]. In previous qualitative studies, women perceived healthcare professionals to be coercive or naggingwhenthesupportwasnottailoredtotheirownreadiness to change [17,20]. Although the Dutch guideline recommends repeateddiscussionofsmokingcessationevenifwomenarenot motivatedtostopsmoking[7],littleevidenceisavailableaboutthe effectiveness of such repetition [32]. This raises the question whether healthcare professionals should persist in discussing
smoking cessationif womenare notready for it.Based onthe needsofthewomenandtheirpartnersinourstudy,healthcare professionalsmightfirstneedtoaskwomeninwhatwayandhow frequentlytheywanttobesupported,soastotailorthesupportto theirreadinesstochange.Thisiscontradictorytotheprincipleof an opt-out referral system in the UK, where women are automaticallyreferredforsmokingcessationsupport[6].
Athirdfindingofourstudyisthatpregnantwomenandtheir partnersperceivesmokingbehaviourastheirownresponsibility. Thisperceivedautonomyinsmokingbehaviourwasnotreported in previous studies, performed in the UK, Australia and New Zealand, to address pregnant women’s support needs [17–20]. However,aDutchstudyamongpeoplewithchronicobstructive pulmonarydisease(COPD)alsoreportedthattheyhadaneedfor autonomyinsmokingbehaviour.Theauthorsstatedthatthiscould berelatedtotheDutchemphasisonindividualism[33]. Further-more,theperceptionofautonomymightbefedbypublichealth campaigns that hold the individual responsible for adopting a healthy lifestyle [34]. Our finding implies that respect for autonomyinthesmokingbehaviourofwomenandtheirpartners isanimportantelementfortailoredsmokingcessationsupport.
Relatedtothewomenandtheirpartners’desireforautonomy in smokingbehaviouristheirwish toreceivemoreinformation abouthowsmokingaffectstheirownhealthandthehealthofthe fetus;womenindicatedthattheypreferredtoseeproof,hoping thatthisinformationwouldmotivatethemtoquitsmoking.This could indicate that to enhance women's motivation to stop smokingmoreattentioncouldbefocusedonprovidingfeedback andpersonalisedinformation[11].IntheUKthis informationis givenintheformofCarbonMonoxide(CO)feedback,foundtobea helpfultoolinmotivatingwomentoquitsmoking[24].COtesting isnotastandardpartoftheDutchguidelineforsmokingcessation supportduringpregnancy,butmightbeanoptiontoexplore[7]. Thewomeninourstudypreferredthehealthcareprofessional toinvolvetheirsocialnetworkinthesmokingcessationsupport. Having ascertainedthe great influenceof partners onwomen’s smoking behaviour [5], previous studies also reported the importance of involving them in smoking cessation support [5,35].Althoughwomeninourstudypreferredtheinvolvement oftheirsocialnetworks,thismightbedifficulttoachievebecause partners and others members of their network are not always willing to be involved and to stop smoking [36]. Despite this discrepancy, a recent Dutch study recommends adjusting the guideline for smoking cessation support toinclude individuals fromwomen’s social network insmoking cessation supportby givingthemadvicetostopsmoking,providinginformationabout third-hand smoke, and referring them for intensive smoking cessationsupport[36].
4.1.Strengthsandlimitations
A strength of this study is its use of multiple methods to increasethevalidityandreliabilityoftheresults.Afterconducting theinterviews,weusedamembercheckandpeerdebriefingto ensure agreement over the results. Furthermore, we involved expertsbyexperienceandresearchersofZorgbelanginthedesign andexecutionoftheinterviews.Theyensuredthattheinterview questionswerephrasedinawaythatmadewomenfeelateaseto sharetheirexperiences,assmokingduringpregnancycouldbea delicateissuetodiscuss.Furthermore,theinvolvementofthese experts made it possible to recruit women with a lower socioeconomicstatus,whoaredifficulttorecruit[37].
Somelimitationsofthisstudymustalsobeacknowledged.One isthataresponsebiasmaybepresentintherecruitmentofthe women and their partners. The women who applied for the interviewmightbemorewillingthanotherwomentosharetheir
needs.Furthermore,becauseweinterviewedonlyasmallnumber ofpartnerswedidnotreachdatasaturationforthem.
4.2.Recommendations
Basedonourresultswecanofferafewrecommendationsto improve the implementation of the guidelines for smoking cessation support and thereby the use of smoking cessation supportbypregnantwomen.Theadaptationsand recommenda-tionsmightalsobevaluableforothercountries.
First, already in an early phase or before pregnancy some womenmightneedtoreceivesupportfocusedonstressreliefand coping with stress. Second, healthcare professionals can best discusssmokingcessationinaneutralway,andtailortheirsupport towomen’sneedsbyaskingthemhowtheywanttobesupported.

The findingsofourstudyindicatethatwomenandtheirpartnershave clearideasabouthowthesupportcouldbeorganised.Tobetter tailorthis supporttowomen’sneeds, thecurrentguidelinesfor professionalsmokingcessationsupportcouldbenefitfromsome adaptations. Moreover, women’s needs for smoking cessation supportmaydifferdependingontheinfluenceofstressintheir livesandtheirmotivationlevels.Thefindingsofourstudyaddthat pregnantwomenandtheirpartnersperceivesmokingbehaviour astheirownresponsibility.Therefore,healthcareprofessionalscan best address smoking cessation in a neutral way, and respect women’s autonomy in their decision about smoking cessation. Moreresearchisneededregardingtheinclusionofwomen’ssocial networks in smoking cessation support. Early involvement of womenandtheirpartnersinthedevelopmentofguidelinescould improve the implementation of the guidelines and the use of smoking cessation support. Healthcare professionals in other countrieswheresmokingduringpregnancyisprevalentmayalso benefitfromtheinsightsprovidedbythisstudy[3].
