Maternal Social Capital and Child Health in VietnamTran TuanTrudy HarphamMary J De SilvaNguyen Thu HuongBill TodPham Thi LanTran Duc ThachSavitri Abeyasekera
In Vietnam there is growing concern about the potential social impact of rapid economic changes. The extent and type of social connectedness, or social capital, may be changing. Studies from other developing countries have demonstrated that social capital is often independently associated with various indicators of well-being, including some aspects of human capital (health and education status). In Vietnam there has only been one previous quantitative study of social capital and this did not consider associations with well-being. The Young Lives project in Vietnam allows the examination of the relationship between maternal social capital and child well-being. With a sample of 1,953 mothers of one-year-olds and 954 mothers of eight-year-olds across five provinces, this study examines whether maternal social capital is associated with child health.
This study found low levels of structural social capital (associational life) and citizenship and high levels of cognitive social capital (trust, etc) and support. While poorer women have even lower levels of structural social capital than their better-off peers, patterns across rural and urban areas are similar.
Maternal social support and high cognitive social capital show the most consistent associations with child health, while associations between maternal social capital and child health are stronger among one-year-old children than among eight-year-olds, with the exception of child mental health and risk of life-threatening illness. The most consistent associations were seen with the mental health of eight-year-olds, with all four indicators of social capital being significantly associated with mental health after other variables have been controlled for. Lastly, there was some evidence to suggest that active membership of formal organisations in Vietnam may be damaging to the health of eight-year-olds but not one-year-olds, with active participation in formal groups being significantly associated with an increase in stunting among eight-year-olds.
The main components of social capital associated with child health are social support and cognitive social capital. High levels of maternal social support are positively correlated with having an educated partner, living in an urban area and better maternal mental health. High cognitive social capital is positively correlated with living in a rural area, having an occupation other than agriculture and better maternal mental health.
There is a need to focus on maintaining the high levels of cognitive social capital and raising the current low level of maternal structural social capital in Vietnam.

Young Lives is an international longitudinal study of childhood poverty, taking place in Ethiopia, India, Peru and Vietnam, and funded by DFID. The project aims to improve our understanding of the causes and consequences of childhood poverty in the developing world by following the lives of a group of 8,000 children and their families over a 15-year period. Through the involvement of academic, government and NGO partners in the aforementioned countries, South Africa and the UK, the Young Lives project will highlight ways in which policy can be improved to more effectively tackle child poverty.

Rapidnationaleconomic growthisoftenaccompaniedbyaweakeningofsocialties,orconnectedness(GrootaertandvanBastelaer,2002).VietnamisundergoingaperiodofrapideconomicchangeanditsachievementsintermsofpovertyreductionhavebeenheraldedbydonorsandbytheVietnamGovernmentasoneofthegreatsuccessstoriesofeconomicdevelopment(JointDonorReport,2003;GoV,2003).AdecadeofGDPgrowthfiguresaveragingaround7percentperannumhaveunderpinnedahalvingofincome-expenditure-consumptionpovertyfrom58percentofthepopulationin1993to29percentin2002.

Changesinsocialconnectednesscanalsoresultfromdemographicphenomenasuchasurbanisation,migrationandtheageingofapopulation.UrbanisationisaparticularlyimportantphenomenoninVietnam.By2020itisestimatedthat55percentofthepopulationwillliveincitiescomparedtolessthan25percenttoday(UNCT,2003).RecentestimateshavesuggestedthatonemillionpeopleayeararemigratingtoVietnam’scities(JointDonorReport,2003).Newmigrantstothecitiescurrentlyfaceadoubledisadvantageinthelossoftheirtraditionalsocialnetworksandthediscriminatorypolicieswithregardtoaccesstobasicservices,housingandpovertyalleviationprogrammes(SavetheChildrenUK,2003andJointDonorReport,2003).

1.2 This study’s approach to social capital
SocialcapitalismostcommonlyassociatedwiththeresearchofBourdieu(1986),Coleman(1990)andPutnam(1993).‘Inattemptingtofindnon-economicfactorstoexplainthesuccessofcertaineconomicprocesses,theseauthorsdrawonconceptssuchastrust,participationincivilsocietyandsocialnetworks,allofwhichformthe“social capital”ofagivencommunity’(vanKemenade,2002p.7).SocialcapitalisoneoffiveassetsinthelivelihoodsconceptualframeworkdevelopedbyDFID(theothersbeingphysical,human,naturalandfinancialassets).However,thereisongoingdebateastowhetheritistrulyaformof‘capital’(eg,seeArrow,2000).Researchhasshownittohaveanindependenteffectonvariouseconomicandotherwelfareindicators,includingphysicalandmentalhealth(GrootaertandvanBastelaer,2002;DeSilvaet al,2005).Socialcapitalcanbethoughtofasthe‘value’ofsocialrelationships,reflectingthequalityandquantityofsocialrelationshipsinagivenpopulation,mostcommonlythosewithinacommunity.Indeed,Quibria(2003)suggeststhatsocialcapitalhasbecomeshorthandfor‘community’.

Althoughsomewritersclaimthatthenegativesideofsocialcapitalisstillignored(eg,Quibria,2003),mostsocialcapitalresearchthesedaysacknowledgesthathighlevelsofsocialcapital,insomecontexts,canbeassociatedwithexclusionofoutsiders,restrictionsonindividualfreedomsandreinforcementofharmfulnorms.Another,morefundamental,criticismofafocusonsocialcapitalisthatitemphasisesthe‘social’ofdevelopmentattheexpenseofthe‘economic’.However,many,includingthecurrentauthors,welcometheadditionalattentiontonon-marketsocialinteractions.
TheapproachtosocialcapitalinYoungLivesavoidsfocussingoneithertrust, norms,etc, or interactionsbutconsidersboth,asrecommendedbymostrecenttextsonsocialcapital(eg,DasguptaandSerageldin,2000).However,thisstudyrecognisestheimportanceofseparating outstructuralsocialcapital(objectivemeasuresofwhatpeople‘do’,suchasmembershipofnetworks)fromcognitivesocialcapital(subjectivemeasuresofwhatpeople‘feel’,suchasnotionsoftrustandreciprocity)(Harpham,GrantandThomas,2002).Itisimportanttoseparatetheseindicatorsofsocialcapitalastheymaynotbecorrelated.Allmeasuresrefertothe‘community’thereforethisstudyonlyaddressesbonding(withincommunity)socialcapitalandnotbridging(linkingtoothercommunitiesorinstitutions)socialcapital.Thisstudyalsoavoidscoveringboththecausesandconsequences(oroutcomes)ofsocialcapitalinthemeasureofsocialcapitalitself.AsPortes(1998)andQuibria(2003)pointout,thisstillhappensinsomestudies.

2.2 Measures
SocialcapitalwasmeasuredusingashortenedversionoftheA-SCATtooldevelopedbyHarpham,GrantandThomas(2002)–aseriesoftenyes/noquestions.ThequestionnairehasbeenqualitativelyvalidatedinVietnam. Structural social capital wasmeasuredby(1)askingrespondentsaboutactivemembershipofformal(women’sunion,co-op,tradeunion,political/social)andinformal(religious,credit,lifeinsurance,sports)groupsintheircommunityduringthelastyear;(2)byrecordingsupportreceivedfrominformal(family,relatives,neighbours,friends,religiousleaders)andformal(communeleaders,governmentofficials,politicians,NGOs)networksduringthelastyear;and(3)byaskingaboutjoiningtogetherwithothercommunitymemberstoaddressanissue/problemandcommunicationwithcommunityleaders(seeTable3).Cognitive social capital wasmeasuredbyaskingrespondentsquestionsabouttrust,senseofbelonging,communityharmonyandperceivedfairness.

Maternal Social Capital and Child Health in VietnamTran TuanTrudy HarphamMary J De SilvaNguyen Thu HuongBill TodPham Thi LanTran Duc ThachSavitri Abeyasekera
In Vietnam there is growing concern about the potential social impact of rapid economic changes. The extent and type of social connectedness, or social capital, may be changing. Studies from other developing countries have demonstrated that social capital is often independently associated with various indicators of well-being, including some aspects of human capital (health and education status). In Vietnam there has only been one previous quantitative study of social capital and this did not consider associations with well-being. The Young Lives project in Vietnam allows the examination of the relationship between maternal social capital and child well-being. With a sample of 1,953 mothers of one-year-olds and 954 mothers of eight-year-olds across five provinces, this study examines whether maternal social capital is associated with child health.
This study found low levels of structural social capital (associational life) and citizenship and high levels of cognitive social capital (trust, etc) and support. While poorer women have even lower levels of structural social capital than their better-off peers, patterns across rural and urban areas are similar.
Maternal social support and high cognitive social capital show the most consistent associations with child health, while associations between maternal social capital and child health are stronger among one-year-old children than among eight-year-olds, with the exception of child mental health and risk of life-threatening illness. The most consistent associations were seen with the mental health of eight-year-olds, with all four indicators of social capital being significantly associated with mental health after other variables have been controlled for. Lastly, there was some evidence to suggest that active membership of formal organisations in Vietnam may be damaging to the health of eight-year-olds but not one-year-olds, with active participation in formal groups being significantly associated with an increase in stunting among eight-year-olds.
The main components of social capital associated with child health are social support and cognitive social capital. High levels of maternal social support are positively correlated with having an educated partner, living in an urban area and better maternal mental health. High cognitive social capital is positively correlated with living in a rural area, having an occupation other than agriculture and better maternal mental health.
There is a need to focus on maintaining the high levels of cognitive social capital and raising the current low level of maternal structural social capital in Vietnam.

Young Lives is an international longitudinal study of childhood poverty, taking place in Ethiopia, India, Peru and Vietnam, and funded by DFID. The project aims to improve our understanding of the causes and consequences of childhood poverty in the developing world by following the lives of a group of 8,000 children and their families over a 15-year period. Through the involvement of academic, government and NGO partners in the aforementioned countries, South Africa and the UK, the Young Lives project will highlight ways in which policy can be improved to more effectively tackle child poverty.
