- Background: Gender inequalities influence the utilization of maternal health services in Vietnam, but little research has been published. This study, therefore, aimed to explore the association between gender inequalities and women's utilization of maternal health services in Vietnam.Methods: The study was conducted in 8 provinces in the South Central Coast region of Vietnam during August 2013 to May 2014. A total of 907 women who delivered a year prior to the date of interview participated in the study. A multiple logistic regression model was used to examine the association between gender inequalities (including sociodemographic determinants of health) and utilization of 4 or more antenatal care (ANC4+) services, institutional delivery, and ever used contraceptive methods.Results: The utilization rate of maternal health services was varied, from 53.9% for ANC4+ to 87.7% for ever used a contraceptive method and 97% for institutional delivery. Ethnicity was identified as the most influential variable out of all sociodemographic determinants of health. Regarding gender inequalities, couple communication was the only variable having significant association with women's utilization of maternal health services.Conclusion: Women's equal role within context of their daily life and relations with their husbands (discussing maternal care with husband and having equal income to husband) supported their use of maternal health services. Therefore, there should be concerted efforts from all relevant stakeholders including the health system to focus on disadvantaged women in planning and delivery of maternal health services, especially to ethnic minority women. Male involvement strategy should be implemented to promote maternal health care, especially during the prenatal and postpartum period. To provide more culturally sensitive and right-based approaches in delivery of maternal health services to disadvantaged women in Vietnam, interventions are recommended that promote male involvement, that is, to engage men in service delivery to adapt and ensure the most appropriate and effective maternal health care.

- Our study aimed to identify the knowledge, attitude, and factors associated with uptake of amniocentesis test amongst pregnant women of advanced maternal age (35+ years old). A cross-sectional survey was performed on 481 participants in 2016. Women with higher educational attainment, higher income level, having a baby with congenital defects, and women with better knowledge and/or attitude about amniocentesis test were more likely to accept the test. Our study suggested the importance of counseling for women and more time should be given for them to absorb information before they make their decision to uptake the amniocentesis test.

Factors associated with four or more antenatal care services among pregnant women : a cross-sectional survey in eight South Central Coast provinces of Vietnam
- 2015
-
Ingår i: International Journal of Women's Health. - 1179-1411. ; 7, s. 699-706
-
Tidskriftsartikel (refereegranskat)abstract
- Background: In Vietnam, four or more antenatal care (ANC4+) visits/services among pregnant women have not been officially reported in the health system. Moreover, the factors associated with the use of ANC4+ services have not been studied in previous studies. In this study, we conducted an exploratory analysis to identify the rate of utilization of ANC4+ services and factors associated with use of ANC4+ services among pregnant women in rural areas of Vietnam.Methods: The study was conducted in eight provinces in the South Central Coast region of Vietnam between August 2013 and May 2014. A total of 907 women, who delivered in the past 1 year, participated in the study. Multivariate logistic regression model was used to examine the association between all potential factors and utilization of ANC4+ services.Results: The rate of utilization of ANC4+ services by women in eight South Central Coast provinces was 53.9%. Factors negatively associated with using ANC4+ services were belonging to ethnic minority groups having lower education, doing informal works, having lower income, having lower knowledge on ANC4+ services, and receiving no financial support from the husband. In particular, financial support from the husband was considered important in improving the use of ANC4+ services by women in rural areas.Conclusion: The study asserted an inadequacy for ANC4+ utilization and can contribute to missed opportunities to achieve better maternal outcomes for women in rural areas of Vietnam. The necessity of introducing ANC4+ services in the national guidelines on maternal health care should be disseminated to health policy-makers. Strategies to increase ANC4+ utilization should focus on knowledge improvement and on poor, low-income, and ethnic minority women.

Healthcare context for knowledge translation in Vietnam : Development and application of the Context Assessment for Community Health (COACH) tool
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The failure to translate evidence into clinical practice has been repeatedly highlighted. This failure is partly attributed to disregarding the context within which healthcare is delivered. The aim of this thesis was to develop and psychometrically evaluate the Context Assessment for Community Health (COACH) tool, and, through that process, provide opportunities to measure aspects of context perceived to be important for Knowledge Translation (KT) interventions in low- and middle-income countries (LMIC).All four studies in this thesis were mainly undertaken in Quang Ninh province, Vietnam during 2008–2014. Study II, however, was also conducted in four other LMICs (Bangladesh, Nicaragua, South Africa, and Uganda). Study I employed inductive content analysis of 16 focus group discussions to explore the influence of context in a community-based facilitation intervention in Vietnam. Studies II and III reported on the development of the COACH tool and assessment of its psychometric properties. Study IV used the COACH tool in a survey among health workers in Vietnam.To date, three sources of evidence regarding validity of the COACH tool have been provided, that is, test content, response processes, and internal instrument structure, with promising psychometric characteristics. The COACH tool could be used as means of characterizing aspects of context ahead of KT interventions, for tailoring KT strategies, and for further understanding of the results of KT interventions.

Tidskriftsartikel (refereegranskat)abstract
- The remarkable increase in Vietnamese economic conditions can increase the birth weight in neonates and better delivery practices among women. The Chi Linh Health and Demographic Surveillance System started in 2004. An open cohort of data consisting of about 57561 people from 17993 households has been followed primarily with respect to demography, economy, and education. The aim of this research is to study secular trends in delivery practice and birth weight in the past decade (2005-2012) in Chi Linh. We found a significant change in delivery rates at hospitals and cesarean section rates, but the birth weights over a decade of drastic economic development were stable. Furthermore, the findings show significant associations of birth weight and delivery practices with the child's sex, mother's age, and household income. Our results might be considered as representative for other similar periurban settings in Vietnam. We suggest that appropriate policies should be developed given the reduction in the use of delivery services in commune health centers in urban areas.

Measuring local healthcare context for knowledge translation in primary and secondary levels of care in northern Vietnam: A cross-sectional study
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- BackgroundThe influence of context in shaping the effectiveness of knowledge translation (KT) is widely recognized. The Context Assessment for Community Health (COACH) tool aims to assess contextual aspects that are of importance for KT in healthcare in low- and middle-income settings. This study used the COACH tool to describe healthcare context as perceived by health workers in primary and secondary levels of care in a northern province in Vietnam and to further evaluate the internal structure of the COACH tool.MethodsThis cross-sectional study administered the COACH tool to 677 eligible health workers in primary and secondary levels of care. The relationships between individual background variables and COACH dimensions were analysed using binary logistic regression. Further, internal construct validity was calculated by a first-order independent cluster model confirmatory factor analysis (CFA).ResultsOverall, the healthcare context was perceived as supportive for KT. Gender, age, and geographic location showed significant relationships to one of the COACH dimensions. Male health workers rated their Commitment to work as lower than female health workers (OR=0.39, 95% CI: 0.20–0.78). There were, however, only minor differences in scores for the dimensions of context, at each health facility as well as between health facilities. The CFA asserted an acceptable internal structure of the COACH tool.ConclusionsThe survey enhanced the understanding of how aspects of the healthcare context for KT are perceived by health workers at primary and secondary levels of care in a province in Vietnam. There was an overall positive perception of the work context with only minor variability, reflecting a ‘receptive to change’ context for KT. This should, however, be interpreted with caution due to the risk of social desirability response bias. The findings on the acceptable internal structure of the COACH tool supports its further use as a valid instrument.

Tidskriftsartikel (refereegranskat)abstract
- Background: The recently developed Context Assessment for Community Health (COACH) tool aims to measure aspects of the local healthcare context perceived to influence knowledge translation in low-and middle-income countries. The tool measures eight dimensions (organizational resources, community engagement, monitoring services for action, sources of knowledge, commitment to work, work culture, leadership, and informal payment) through 49 items. Objective: The study aimed to explore the understanding and stability of the COACH tool among health providers in Vietnam. Designs: To investigate the response process, think-aloud interviews were undertaken with five community health workers, six nurses and midwives, and five physicians. Identified problems were classified according to Conrad and Blair's taxonomy and grouped according to an estimation of the magnitude of the problem's effect on the response data. Further, the stability of the tool was examined using a test-retest survey among 77 respondents. The reliability was analyzed for items (intraclass correlation coefficient (ICC) and percent agreement) and dimensions (ICC and Bland-Altman plots). Results: In general, the think-aloud interviews revealed that the COACH tool was perceived as clear, well organized, and easy to answer. Most items were understood as intended. However, seven prominent problems in the items were identified and the content of three dimensions was perceived to be of a sensitive nature. In the test-retest survey, two-thirds of the items and seven of eight dimensions were found to have an ICC agreement ranging from moderate to substantial (0.5-0.7), demonstrating that the instrument has an acceptable level of stability. Conclusions: This study provides evidence that the Vietnamese translation of the COACH tool is generally perceived to be clear and easy to understand and has acceptable stability. There is, however, a need to rephrase and add generic examples to clarify some items and to further review items with low ICC.

Smoking Initiation and Cessation among Youths in Vietnam : A Longitudinal Study Using the Chi Linh Demographic-Epidemiological Surveillance System (CHILILAB DESS)
- 2017
-
Ingår i: AIMS PUBLIC HEALTH. - : AMER INST MATHEMATICAL SCIENCES-AIMS. - 2327-8994. ; 4:1, s. 1-18

Tidskriftsartikel (refereegranskat)abstract
- Study of smoking initiation and cessation is particularly important in adolescent population because smoking prevention and cessation at this time may prevent several health consequences later in life. There is a very limited knowledge about the determinants of smoking initiation and cessation among youths in Vietnam. This limits the development and implementation of appropriately targeted anti-smoking prevention interventions. This study applied pooled data from 3 rounds of a longitudinal survey in the Chi Linh Demographic-Epidemiological Surveillance System (CHILILAB DESS) in a northern province in Vietnam to analyse the determinants of smoking initiation and cessation among youths. The total of youths in the first round, second, and third rounds was 12,406, 10,211, and 7,654, respectively. The random-effects logit model controlling for both time-variant and time-invariant variables was conducted to explore the associated factors with new smokers and quitters. We found an increase trend of new smokers (7.0% to 9.6%) and quitters (27.5% to 31.4%) during 2009-2013. Smoking initiation and cessation are the result of multifactorial influences of demographic and health behaviours and status. Demographic background (older youths, male, unmarried youths, and youths having informal work) and health behaviours and status (youths who had smoking family members and/or smoking close friends, and had harmful drinking) were more likely to initiate smoking and more difficult to quit smoking. Among these variables, youths who had smoking close-friends had the highest likelihood of both initiating smoking and failed quitting. Our results could represent the similar health problems among youths in peri-urban areas in Vietnam. Further, our findings suggested that anti-smoking interventions should involve peer intervention, integrated with the reduction of other unhealthy behaviours such as alcohol consumption, and to focus on adolescents in their very early age (10-14 years old).

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: In northern Vietnam the Neonatal health - Knowledge Into Practice (NeoKIP, Current Controlled Trials ISRCTN44599712) trial has evaluated facilitation as a knowledge translation intervention to improve neonatal survival. The results demonstrated that intervention sites, each having an assigned group including local stakeholders supported by a facilitator, lowered the neonatal mortality rate by 50% during the last intervention year compared with control sites. This process evaluation was conducted to identify and describe mechanisms of the NeoKIP intervention based on experiences of facilitators and intervention group members.METHODS: Four focus group discussions (FGDs) were conducted with all facilitators at different occasions and 12 FGDs with 6 intervention groups at 2 occasions. Fifteen FGDs were audio recorded, transcribed verbatim, translated into English, and analysed using thematic analysis.RESULTS: Four themes and 17 sub-themes emerged from the 3 FGDs with facilitators, and 5 themes and 18 sub-themes were identified from the 12 FGDs with the intervention groups mirroring the process of, and the barriers to, the intervention. Facilitators and intervention group members concurred that having groups representing various organisations was beneficial. Facilitators were considered important in assembling the groups. The facilitators functioned best if coming from the same geographical area as the groups and if they were able to come to terms with the chair of the groups. However, the facilitators' lack of health knowledge was regarded as a deficit for assisting the groups' assignments. FGD participants experienced the NeoKIP intervention to have impact on the knowledge and behaviour of both intervention group members and the general public, however, they found that the intervention was a slow and time-consuming process. Perceived facilitation barriers were lack of money, inadequate support, and the function of the intervention groups.CONCLUSIONS: This qualitative process evaluation contributes to explain the improved neonatal survival and why this occurred after a latent period in the NeoKIP project. The used knowledge translation intervention, where facilitators supported multi-stakeholder coalitions with the mandate to impact upon attitudes and behaviour in the communes, has low costs and potential for being scaled-up within existing healthcare systems.

- BackgroundAnnually, 2.8 million neonatal deaths occur worldwide, despite the fact that three-quarters of them could be prevented if available evidence-based interventions were used. Facilitation of community groups has been recognized as a promising method to translate knowledge into practice. In northern Vietnam, the Neonatal Health – Knowledge Into Practice trial evaluated facilitation of community groups (2008–2011) and succeeded in reducing the neonatal mortality rate (adjusted odds ratio, 0.51; 95 % confidence interval 0.30–0.89). The aim of this paper is to report on the process (implementation and mechanism of impact) of this intervention.MethodsProcess data were excerpted from diary information from meetings with facilitators and intervention groups, and from supervisor records of monthly meetings with facilitators. Data were analyzed using descriptive statistics. An evaluation including attributes and skills of facilitators (e.g., group management, communication, and commitment) was performed at the end of the intervention using a six-item instrument. Odds ratios were analyzed, adjusted for cluster randomization using general linear mixed models.ResultsTo ensure eight active facilitators over 3 years, 11 Women’s Union representatives were recruited and trained. Of the 44 intervention groups, composed of health staff and commune stakeholders, 43 completed their activities until the end of the study. In total, 95 % (n = 1508) of the intended monthly meetings with an intervention group and a facilitator were conducted. The overall attendance of intervention group members was 86 %. The groups identified 32 unique problems and implemented 39 unique actions. The identified problems targeted health issues concerning both women and neonates. Actions implemented were mainly communication activities. Communes supported by a group with a facilitator who was rated high on attributes and skills (n = 27) had lower odds of neonatal mortality (odds ratio, 0.37; 95 % confidence interval, 0.19–0.73) than control communes (n = 46).ConclusionsThis evaluation identified several factors that might have influenced the outcomes of the trial: continuity of intervention groups’ work, adequate attributes and skills of facilitators, and targeting problems along a continuum of care. Such factors are important to consider in scaling-up efforts.

- This study presents a new two-way Gysel combiner based on an air-dielectric stripline which allows to handle very high radio-frequency power levels with low-loss suitable for power combination in accelerator applications. The insertion loss of the combiner is 0.1 dB (2%). A thick stripline implementation allows improving the power capability in both continuous wave (CW) and pulsed operation. In addition, a mechanical tuner allows compensating for assembly and fabrication discrepancies. A methodology of designing the Gysel combiner as well as high-power measurements up to 22 kW in pulsed mode are presented. Simulations and measurements are in very good agreement.

- This study aimed to explore the association of demographic and socioeconomic characteristics and imbalanced sex ratio at birth (SRB) in Chi Linh district, Hai Duong. The data were collected from a longitudinal study using a community-based periodic, referred as Chi Linh Health and Demographic Surveillance System (CHILILAB HDSS) during 2004 to 2013. A total of 7568 children were analyzed. Results showed that SRB in Chi Linh dramatically increased to the imbalanced sex ratio (114.6 boys to 100 girls) by 2013. SRB was associated with birth order and sex of preceding siblings. SRB was extremely high among families without any sons (136/100). SRB was highest among families having third or more children (175/100). Imbalanced SRB was more likely to occur among women working in small business/homemakers and others, women who attained high education level, and women in wealthy households. We suggested further efforts to tackle imbalanced SRB in periurban areas in Vietnam.
