SUMMARY
Introduction: Postnatal depression (PND) is an important public health issue due to its
impact on maternal wellbeing, infant development, and family cohesion The estimated prevalence of PND during the first 12 months post-partum ranges between10-20% worldwide Whilst PND used to be considered a syndrome only occurring in western countries, there is now evidence that it occurs throughout the world, and often at higher rates in low and middle-income countries To date, there has been little research into PND in South East Asia and only two community-based surveys in Vietnam, one in Ho Chi Minh City in 1999 and one in Hanoi and Ha Nam in 2009 This study will investigate health worker attitudes about risk and protective factors for PND among women in Thua Thien Hue province in central Vietnam
Methodology: In 2009, 23 health professionals participated in qualitative exploratory research
of postnatal depression in Hue This included two focus groups with 12 health professionals who completed a concept mapping process, and in-depth interviews with another 11 health
professionals Results: Many factors relating to postnatal depression were identified including
socio-economic status, son preference, mother’s health, infant health, social support from family and the community, and health promoting behaviours In-depth interviews highlighted community knowledge and attitudes surrounding PND such as traditional confinement practices
and fear of experiencing stigma Conclusion: The findings of this research will be used to plan
a substantial community-based quantitative survey in order to establish prevalence of PND and surrounding social determinants in central Vietnam
1 Introduction
Postnatal depression (PND) is a significant public health issue which not only impacts maternal wellbeing, but also infant growth and development, and family cohesion Prevalence of PND is estimated to be between 10-20% worldwide, although rates vary within and between countries Before the 1980’s, it was assumed that PND only occurred in western countries However once PND began to be measured internationally using standardised tools, it became apparent it was a genuine universal
Trang 2disorder showing similar symptoms across cultures Emerging evidence suggests the prevalence of PND may be higher in low and middle income countries than in high income countries, and carry considerable social and economic consequences However less than 10% of low and middle income countries have data available
Socio-cultural factors are very influential in the aetiology and progression of perinatal mental health disorders Social risk factors of PND identified in Hong Kong, China, Singapore and Thailand include unwanted pregnancy, intimate partner violence, relationships with extended family (particularly in-laws), maternal self esteem, infant temperament and socio-economic status Son preference is cited as an influential factor
of PND in China, Hong-Kong, Taiwan and Korea In mainland China, mothers who gave birth to a girl are twice as likely to suffer from PND A study of 252 postpartum women in Goa, India, also found that the risk of PND following disappointment about the infant’s gender had an odds ratio of 3.3 (p = 0.002) In Vietnam, son preference has not been studied in relation to PND However Pham et al (2008) state that the national reproductive health policy can create pressure to have a son within two births
Studies of perinatal mental health have been conducted in both the north and south of Vietnam In a sample of 506 women in HCMC, 33% of women were found to have PND, and 19% of participants acknowledged thinking about suicide In the north
of Vietnam, a study of 364 postpartum women from Hanoi and Ha Nam province found that 29.9% had a common mental disorders (CMD) and that CMD were more common
in rural areas Other studies have found that 20% of mothers of one year olds had anxiety or depression in Vietnam, and that between 8 and 16.9% of recorded perinatal deaths could be attributed to suicide There is currently no data on PND from central Vietnam The purpose of this research is to identify risk and protective factors that health professionals in Thua Thien Hue, Vietnam, perceived to be related to PND in order to plan for a larger epidemiological study of maternal mental health in the area
2 Methodology
Methodological Approach: The theoretical approach of this research project
was community based participatory research (CBPR) CBPR aims to draw on multiple sources of expertise when deciding what health risks matter, what causes them and what can be done about them In social epidemiology, CBPR is used to increase the rigor of descriptive research through identifying social determinants of health through collaboration with local stakeholders
Study Site: This study was conducted in Thua Thien Hue province in Central
Vietnam in collaboration with Hue University of Medicine and Pharmacy
Participants: For the focus groups, a purposive sample of twelve maternal and
child health professionals were recruited from three commune health centres within 10km of Hue city, and one Provincial hospital Nine midwives with 2-32 years
Trang 3experience, and three doctors with 15-18 years experience participated in 2 two-hour sessions Another eleven experts in maternal health and mental health such as Obstetricians and Psychiatrists participated in in-depth interviews
Ethics: This study has ethical approval from both Queensland University of
Technology and Hue University of Medicine and Pharmacy
Methods: In-depth interviews lasted 40-60 minutes and were recorder on an
MP3 player with the interviewee’s permission If the interviewer did not wish to be recorded the researcher took detailed notes Interviews were either conducted in English
or translated simultaneously The interview transcripts were then analysed into themes using NVivo 8 software
For the focus groups, a concept mapping process developed by Trochim (1989) was used Trochim’s concept mapping is a structured group process which both describes concepts as well as quantifying the strength of conceptual relationships The focus groups were conducted by two Vietnamese facilitators, who translated materials into English at the end of the workshops At the end of the concept mapping process, the results are visually represented as concept ‘maps’ using ‘Concept Systems’ software
Trochim concept mapping uses the following steps:
Brainstorming: Participants were given a definition of postnatal depression and it’s common symptoms, and asked to think of any factors they thought might be related to it, whether positive or negative
Sorting: Each participant then received a packet of the statements printed on cards, and were asked to sort them into piles ‘in a way that made sense to them.’ The rules were that each card could only be used once, and to make more than one pile Once they had finished the individual sorted piles were collected and entered into Concept Systems software for analysis
Rating: Each participant was then asked to rate each statement from 1 ‘least likely’ to 5 ‘most likely’ according to the following headings: ‘likely to cause PND’ and ‘likely to protect against PND.’ This information was also analysed with Concept Systems software
Verification: Once the information was analysed, the groups then met again
to look at the concept maps and decide if they accurately reflected their previous work
3 Results
3.1 Brainstorming: Participants brainstormed 46 statements to include in the
sorting and rating activities A list of the statements is outlined in figure one
3.2 Sorting: From the sorting exercise, a concept map was produced (see figure
Trang 4two) Each of the 46 statements is located as a point on the map Statements that were sorted together more frequently appear closer to each other on the map and represent similar themes than statements more distant from them The statements fitted naturally into eight thematic clusters, which are enclosed by the polygons on the map
3.3 Rating: The next two maps show how the eight clusters were rated by
participants as ‘most likely to cause PND,’ and ‘most likely to protect against PND.’ The rating map depicts the relative average rating on a 5 point likert scale (where 1 = least likely, 5 = most likely) in relation to being likely to cause PND The number of layers represents how strongly participants rated a statement as being likely to cause PND The more layers there are, the more participants rated statements in this cluster as likely to cause PND The layers represent a double averaging – across all participants and all of the statements in each cluster
Figure three clearly shows that the clusters ‘negative stressors,’ and ‘mother’s emotions and worry’ were rated as highly likely to be risk factors for PND with average ratings of 3.73 to 4.24 ‘Mother’s health’ and ‘baby’s health’ were also considered to be risk factors with average ratings of 3.23 to 3.75, but were not rated as highly as the previous two clusters ‘Economics’ had an average rating of 2.73 to 3.23, which means
it was not considered as influential as other social and health factors in causing PND
Figure four represents statements participants perceived as most likely to protect against PND Economics was moderately rated as a protective statement (average rating
of 2.72 to 3.08), although it should be noted participants put positive as well as negative statements about economics in this category Interestingly, ‘family aspects’ and ‘society and friendship’ (average 3.82 to 4.91) were rated more likely to be protective than factors explicitly categorised and labelled in focus groups as ‘protective factors.’ The statements in the ‘protective factors’ cluster were mainly about individual health behaviours such as exercise and rest, whereas ‘family aspects’ and ‘society and friendship’ all describe personal relationships and connections
3.4 Interpretation of Maps
In the second focus group, participants were shown the maps and decided if they considered the clusters generated to be meaningful Both groups agreed that statement
16 ‘sleeplessness because of the baby’ should be moved to the cluster ‘Mother’s Health’ The group of 6 midwives thought that husbands needed a category of their own, apart from other family aspect, however it was decided overall that this wouldn’t be changed
In general, both groups thought the maps represented their ideas accurately
3.5 In – depth interviews
In-depth interviews provided more depth to many of the themes discussed in the focus group, including themes of son preference and also stigma about accessing mental
Trang 5health services The quote below explains women’s reluctance to access health services:
“They don’t come to the hospital except for the serious case, the reason is they don’t want to meet with the psychiatrist because sometimes the depression in women makes them not want to take care of the baby and if they go to the psychiatrist, maybe they, the psychiatrist will say they are lazy or that they don’t love the baby.”
One of the interviews provided the following vignette about a woman suffering from possible PND in relation to son preference:
Interviewee: She has a patient, a woman who is a teacher, she had the first baby
but unfortunately she is a girl, so after delivery she calls this postnatal depression because the woman don’t like to contact with other people, she just lies, the back of hers
to the baby and doesn’t want to eat, she didn’t want to eat and didn’t want to talk to other people, because of the gender… Because when she was pregnant and she took an ultrasound and the doctor said that this was a boy and the husband was very hopeful, but after delivery the baby was a girl so the husband was a little bit disappointed and it makes the woman feel bad
4 Discussion
Overall, the concept mapping exercise allowed participants to identify risk and protective factors of PND both individually and as a group Participants naturally sorted the statements into eight clusters, some which were previously in the literature on PND such as maternal health, infant health, social relationships, economics and family relationships Interestingly, some of the statements that emerged are not previously identified in the literature such as ‘good atmosphere,’ ‘worry about beauty and physical appearance,’ ‘enough rest, sleeping late,’ ‘the grandparents not accepting the child and sending it to an orphanage’ and statements regarding son preference The fact infant gender was mentioned in five separate statements highlights its importance This is congruent in other literature from Asia but is yet to be explored in - depth in Other statements in the ‘emotion and psychology’ cluster such as ‘physical appearance,’ ‘low self esteem within the community,’ and ‘gender of the baby the husband didn’t want’ have also not been explored in relation to each other before
Mother’s health, baby’s health and economics are routinely mentioned in the literature about PND from other countries, but were not considered as important as categories including social support Rating social factors more highly than economics as
a risk factor for PND is also consistent with the literature on risk factors for PND in developing countries Vietnamese mothers have very high levels of social support, with one study showing 85% of mothers received support from two or more sources Strong social support positively affects maternal coping, child nutritional status and cognitive development The benefits of supportive nurturing family relationships can override even severe economic adversity in protecting against common perintatal mental
Trang 6disorders
In-depth interviews added depth to the themes mentioned above They also highlighted that many women suffering mental health issues in Hue were unlikely to seek treatment due to little knowledge about PND or fear of experiencing stigma It is internationally recognised that large proportions of people suffering from common mental disorders in low and middle income countries receive no treatment due to underuse of, and poor access to health services and stigma In a study of maternal mental health in northern Vietnam, none of the women diagnosed with a CMD had ever received mental health care
Limitations of this method include the fact it requires resources that may not be easy to attain such as proprietary software One major limitation of the method’s accessibility is that Concept Systems is yet to be available with fonts for other languages Also, as this is a qualitative method, the results are not generalisable, but are only representative of the ideas of the group that participated Hence the results are useful for planning further studies but not identifying social determinants at a population level
5 Conclusion
Overall, this exploratory research was useful in identifying health professional’s perspectives about the social determinants likely to influence PND in Hue The concepts resulting from this research will be used to inform a larger quantitative epidemiological study of social determinants of PND in Hue in 2010
