Abstract: Comprehensive bans on tobacco advertising and promotion were introduced through tobacco control legislation in Viet Nam, but it has been established that violations of the bans are very common. This study was conducted to explore the trend in violations of bans on tobacco advertising and promotion at points of sale in Viet Nam in the past six years and to explore any differences in the violation situations before and after the Law on Tobacco Control came into effect on 1st May 2013. Quantitative data were collected through observation of violations of the bans on tobacco advertising and promotion at points of sale in 10 provinces throughout Viet Nam in four survey rounds (2009, 2010, 2011, and 2015). Variation in violation prevalence over time was examined by chi-square test using a Bonferini method. Binary logistic regression was employed to identify the factors that may have influences on different types of violation. A level of significance of p<0.05 was used for all tests in this article. The most common form of violation was the display of more than one pack/one carton of a cigarette brand. Violation of bans on tobacco advertising increased while violations on promotion ban and on displaying tobacco decreased through time. Some factors associated with the tobacco advertising and promotion bans included surveyed years, types of points of sale, regions and areas where the points of sale were located. The enforcement of the bans did not improve even after the issuance and the enactment of the Law on Tobacco Control. This suggests that the monitoring and enforcement of bans on tobacco advertising and promotion at points of sale should be strengthened. Penalties should be strictly applied for violators as indicated in the current tobacco control legislation.

Abstract: Perinatal domestic violence (P-DV) is a common form of violence experienced by women and is associated with adverse impacts on their own physical and mental health and that of their offspring. Illuminating the risk factors for and potential effects of P-DV, and promising interventions is essential for informing policies to reduce P-DV and mitigate its negative impacts. This umbrella review of recent high-quality systematic reviews and meta-analyses of research on P-DV provides a systematic synthesis of current knowledge relating to the prevalence, risk factors for, possible outcomes of, and interventions to reduce and prevent P-DV. Thirteen reviews identified through systematic searches of computerised databases, manual search and expert consultation met our inclusion criteria (i.e., English systematic reviews and/ or meta-analyses that were from recent ten years, focused on women exposed to P-DV, assessed risk factors, possible outcomes, and/ or interventions, and were of fair to high methodological quality). Our results suggest that while there is a growing understanding of risk factors and possible outcomes of P-DV, this knowledge has far been translated into effective interventions for P-DV. P-DV intervention programmes that have been subject to rigorous evaluation are mostly relatively narrow in scope and could benefit from targeting a wider range of maternal and child wellbeing outcomes, and perpetrator, relationship, and community risk factors. The overall quality of the evidence syntheses in this field is reasonable however, future studies should involve multiple reviewers at all key stages of systematic reviews and meta-analyses to help enhance the reliability of review conclusions.

Abstract: There is a gap in the literature on the understanding of the general Vietnamese population toward dengue fever (DF). This study aimed to explore knowledge, attitudes, practice (KAP) of dengue fever among Vietnamese participants and the potential associated factors. A cross-sectional study was conducted among 330 patients at the Bach Mai Hospital in Northern Vietnam. A Tobit regression model was utilized to investigate the associated factors. The average knowledge score was 4.6/19. Respondents perceived their risk of DF infection to be very low (39.5%) to low (20.7%) and had a neutral attitude about the necessity of hospitalization when being infected with DF (60.9%). A total of 17.6%, 9.8% and 6.6% of respondents reported frequently changing water, properly disposing of waste and covering water storage containers to eliminate larvae. Gender, education level, duration of illness and travel history were correlated with knowledge. Occupation, the presence of DF in the neighborhood, mosquito density at home and DF symptom severity were associated with attitudes. Occupation, mosquito density at home, type of patient, knowledge and attitudes were associated with practices. To enhance the KAP towards DF, further efforts should first be directed to improve knowledge through education, especially at the school level and people in less developed areas.

Abstract: Despite the detrimental effects and life-course health consequences of violence exposure, relatively few studies have adequate capacity to investigate the evolution of violence from childhood to motherhood. This study aims to examine the cyclical nature of childhood abuse and prenatal inter-partner violent victimization (p-IPV) and its adverse impact on childbirth trauma and exclusive breastfeeding (EBF) practice in Vietnam. Using a prospective birth cohort, 150 pregnant women were recruited in the third trimester of pregnancy in Hue city in central Vietnam (Wave 1-Baseline) and re-interviewed approximately three months after delivery (Wave 2-Follow-up). The direct and indirect effects of violent victimization on subsequent childbirth experience (measured by Birth Memories and Recall Questionnaire) and EBF practice were estimated by using augmented-inverse-probability-weighted models, sensitivity analysis, and structural equation model. Detrimental and prolonged effects of the inter-generational cycle of violence transverse childhood to motherhood. Women who experienced either childhood abuse or p-IPV violence were more likely to experience negative emotional childbirth memories [ARR 1.21, 95 % CI (1.04, 1.39)]. Evidence also suggested that not continuing to exclusively breastfeed at 3 months post-partum was strongly associated with prenatal depression, young age, and perceived low social status during pregnancy. Perceived strong connectedness among extended family members and social networks (i.e. nexus among family, friends, and neighborhood) provided a buffering effect by preventing EBF termination. This research provides insights into the protective role of social connectedness in improving breastfeeding practice. It is vital to establish wholistic antenatal care and social service system to offer specialized support and response for victims of violence and mitigate the long-term sequelae of traumatic events.

Abstract: Girls exposed to violence have a high risk of being victimized as adults and are more likely than non-abused women to have children who are treated violently. This intergenerational transmission may be especially serious when women suffer violence during pregnancy and early motherhood, as it impairs maternal wellbeing and infant health and development. This study examined the intergenerational effects of being exposed to childhood maltreatment (CM) and prenatal intimate partner violence (p-IPV) on perinatal mental distress and birth outcomes in central Vietnam. A birth cohort study in Hue City, Vietnam was conducted with 150 women in the third trimester of pregnancy (Wave 1) and 3 months after childbirth (Wave 2). Using multivariable logistic regression models, augmented inverse-probability-weighted estimators and structural equation modelling (SEM), we analyzed a theoretical model by evaluating adjusted risk differences and pathways between CM, p-IPV and subsequent perinatal adversity and indicators of infant health problems. One in two pregnant women experienced at least one form of CM (55.03%) and one in ten pregnant women experienced both CM and p-IPV (10.67%). Mothers who experienced p-IPV or witnessed IPV as a child were approximately twice as likely to experience poor mental health during pregnancy [ARR 1.94, 95% CI (1.20–3.15)]. Infants had a two-fold higher risk of adverse birth outcomes (low birth weight, preterm birth, admission to neonatal intensive care) [ARR 2.45 95% CI (1.42, 4.25)] if their mothers experienced any form of p-IPV, with greater risk if their mothers were exposed to both CM and p-IPV [ARR 3.45 95% CI (1.40, 8.53)]. Notably, significant pathways to p-IPV were found via adverse childhood experience (ACE) events (β = 0.13), neighborhood disorder (β = 0.14) and partner support (β = − 1.3). These results emphasize the detrimental and prolonged nature of the effect of violence during childhood and pregnancy. Exposure to childhood maltreatment and violence during pregnancy increases the risk of maternal mental health difficulties and adverse birth outcomes. Antenatal care systems need to be responsive to women’s previous experiences of violence and maternal mental health. The significant protective role of partner support and social support should also be considered when designing tailored interventions to address violence during pregnancy.

Abstract: This paper enumerates and characterizes latent classes of adverse childhood experiences and investigates how they relate to prenatal substance use (i.e., smoking, alcohol, and other drugs) and poor infant outcomes (i.e., infant prematurity and low birthweight) across eight low- and middle-income countries (LMICs). A total of 1189 mother-infant dyads from the Evidence for Better Lives Study cohort were recruited. Latent class analysis using the Bolck, Croon, and Hagenaars (BCH) 3-step method with auxiliary multilevel logistic regressions was performed. Three high-risk classes and one low-risk class emerged: (1) highly maltreated (7%, n = 89), (2 ) emotionally and physically abused with intra-familial violence exposure (13%, n = 152), (3), emotionally abused (40%, n = 474), and (4) low household dysfunction and abuse (40%, n = 474). Pairwise comparisons between classes indicate higher probabilities of prenatal drug use in the highly maltreated and emotionally abused classes compared with the low household dysfunction and abuse class. Additionally, the emotionally and physically abused with intra-familial violence exposure class had higher probability of low birthweight than the three remaining classes. Our results highlight the multifaceted nature of ACEs and underline the potential importance of exposure to childhood adversities on behaviors and outcomes in the perinatal period. This can inform the design of antenatal support to better address these challenges.

Abstract: Measures that produce valid and reliable antenatal depressive symptom scores in low-resource country contexts are important for efforts to illuminate risk factors, outcomes, and effective interventions in these contexts. Establishing the psychometric comparability of scores across countries also facilitates analyses of similarities and differences across contexts. To date, however, few studies have evaluated the psychometric properties and comparability of the most widely used antenatal depressive symptom measures across erse cultural, political, and social contexts. To address this gap, we used data from the Evidence for Better Lives Study-Foundational Research (EBLS-FR) project to examine the internal consistency reliability, nomological network validity, and cross-country measurement invariance of the nine-item version of the Patient Health Questionnaire (PHQ-9) in antenatal s les across eight low-resource contexts. We found that the PHQ-9 scores had good internal consistency across all eight countries. Correlations between PHQ-9 scores and constructs conceptually associated with depression were generally consistent, with a few exceptions. In measurement invariance analyses, only partial metric invariance held and only across four of the countries. Our results suggest that the PHQ-9 yields internally consistent scores when administered in culturally erse antenatal populations however, the meaning of the scores may vary. Thus, interpretation of PHQ-9 scores should consider local meanings of symptoms of depression to ensure that context-specific conceptualizations and manifestations of antenatal depressive symptoms are adequately reflected.

Abstract: A mixed design approach was performed to assess the CD4 count levels over time and their associated factors among 362 HIV patients on ART from clinics with HIV testing and counseling (ART-HTC) services and those with general healthcare (ART-GH) services. Longitudinal CD4 count data were retrospectively collected from medical records. Sociodemographic, clinical, alcohol use and smoking characteristics were obtained via face-to-face interviews. Multivariate mixed effect linear regression was utilized to determine the association. We found that HIV patients at ART-GH clinics were more likely to achieve higher CD4 counts over time compared to patients at ART-HTC clinics. Additionally, having an increase in CD4 counts was found to be associated with having longer duration of ART and higher baseline CD4 levels. Cigarette smoking and hazardous alcohol use, however, were not associated with CD4 count improvement. Our findings suggest that combining HTC and GH services might provide a synergistic benefit in ART treatment outcomes through an improved access to comprehensive HIV healthcare services for HIV patients on therapy.

Abstract: Background: The emergence of HIV drug resistance (HIVDR) is an unavoidable consequence of antiretroviral therapy (ART), and HIVDR early warning indicators (EWIs) could specifically assess factors at in idual clinics associated with HIVDR. Thus, the present study aimed to collect data on EWIs for HIV/AIDS at 42 outpatient clinics (OPCs) in 25 northern provinces and cities of Vietnam in 2012. Methods: A retrospective cohort study was conducted. Data was collected from 42 OPCs in 25 northern provinces between October and December 2012. The information was collected retrospectively from outpatient records from 2008 to 2011. Results: In total, 99.8% ART patients were prescribed the correct regimen when starting ART treatment. All facilities met the target of under 20% patients lost to follow-up at 12 months. A total of 33/42 facilities reached the goal for on-time appointment keeping and 37/42 facilities achieved the target of first-line retention after 12-month ARV treatment. Conclusions: EWIs should be performed routinely in HIV/AIDS facilities. The data collected will contribute to monitoring, supervision, periodic assessment, and future plans for HIV/AIDS care and treatment programs in the area.

Abstract: By 2020, the Vietnamese government has committed to having 90% of patients receiving ART as well as 90% of those on ART having successful viral suppression. Factors that influence adherence to ART among patients are essential to allowing the adequate care. This study was conducted across 8 outpatient clinics in Hanoi and Nam Dinh province and included 1133 patients living with HIV. Socioeconomic factors such as marital status, education, employment as well as health-related quality of life improvements were investigated as potentially being associated with adherence rates of ART patients. Through multivariate logistic regression analysis with self-reported ART adherence and VAS scores, this study was able to identify marital status and employment as two factors associated with positive adherence scores. Similarly, health problems, stigmatization, and duration on ART were associated negatively with ART adherence. Knowing that these factors may be linked to adherence rates, they can be preemptively managed with patients to enhance adherence rates and achieve successful viral suppression.

Abstract: This cross-sectional study assessed the quality of life and related factors of Vietnamese women during perimenopause in terms of vasomotor, psychosocial, physical, and sexual aspects. A cross-sectional study on 400 middle-aged women was conducted in Hung Yen, a delta province in Vietnam. Data about socioeconomic characteristics, daily activity patterns, quality of life in terms of vasomotor, psychosocial, physical, and sexual aspects, and level of social support were collected. Tobit multivariate regression model was used to identify factors related to the quality of life among participants. The symptoms of perimenopause appeared to worsen with the increase of age and the existence of such health issues as migraine and diabetes. Meanwhile, exercises, recreational activities, and social support appeared to alleviate the negative impact of perimenopausal symptoms on women. It is important to address the care needs of women during perimenopausal age, especially their sexual well-being, and development of specific healthcare services and programs focusing on sport, entertainment, and support for women in perimenopause should be facilitated.

Abstract: Methadone Maintenance Treatment (MMT) program has been considered a medium through which human immunodeficiency virus (HIV) risks assessment and prevention on drug use/HIV-infected population can be effectively conducted. Studies concerning the implementation of such idea on patients in remote, under-developed areas, however, have been limited. Having the clinics established in three mountainous provinces of Vietnam, this study aimed to evaluate the changes in knowledge of HIV, perceived risk, and HIV testing uptake of the patients. A longitudinal study was conducted at six MMT clinics in three provinces with a pre- and post-assessments among 300 patients. Outcomes of interest were compared between baseline and after 12 months. The magnitude of changes was extrapolated. The proportion of participants reporting that their HIV knowledge was not good fell by 4.4% (61.3% at the baseline vs. 56.8% at 12 months). The significant improvement seen was in the knowledge that needle sharing was a mode of transmission (82.7% vs. 89.6%). Nevertheless, the majority of participants reportedly considered mosquitoes/insect and eating with the HIV-infected patient were the route of transmission at both time points (84.7% vs. 89.1%, 92.2% vs. 93.3%, respectively). This study found a limited improvement in HIV knowledge and testing uptake among MMT patients following a 12-month period. It also highlighted some shortcomings in the knowledge, attitudes and practices (KAP) of these patients, in particular, incorrect identification of HIV transmission routes, among patients both at program initiation and follow-up. The findings lent support to the argument for enhancing education and counseling efforts at MMT clinics regarding HIV, as well as for improving access to preventive and health care services through the integration of MMT/HIV services.

Abstract: Background We evaluated the satisfaction and improvement in learning outcomes of students taking a distance course in Public Health facilitated by the Institute for Preventive Medicine and Public Health at the Hanoi Medical University and the State University of New York at Albany. Methods A total of 36 students participated in pre- and post- course surveys online. We developed the Vietnamese E-Learning Student Outcomes Profile (VESOP) to evaluate the impact of distance learning methods on students’ learning outcomes. Factor analysis was applied to construct the measure items into five domains: Academic Skills, Intellectual Abilities, Interactions, Responsibility and Educational Engagement. Multivariate regression models, selected using stepwise approach, determined factors associated with changes in students’ learning outcomes. Student satisfaction with the course was assessed by determining their willingness to participate in and pay for future distance learning courses. Results The students showed moderate improvement in “Interactions” and large improvements in the other four domains. Factors associated with improvements included previous academic performance, English proficiency, ease of access to the internet and computers, and time spent studying. All students passed the course, all would be willing to take another distance learning course, and 26 students would be willing to pay for such as course with certification. Conclusions Findings of this study highlight the potential of distance learning as a complementary educational method that could greatly benefit Public Health students. It encourages and supports the development of such training programs for Public Health students in Vietnam.

Abstract: Measures that produce valid and reliable antenatal depressive symptom scores in low resource country contexts are important for research efforts to better understand risk factors, outcomes, and effective interventions in these contexts. Establishing the psychometric comparability of scores across countries also facilitates cross-country analysis of similarities and differences across contexts. To date, however, very few studies have evaluated the psychometric properties and comparability of widely used antenatal depressive symptom measures across erse cultural, political and social contexts. To address this gap, we used data from the Evidence for Better Lives Study – Foundational Research (EBLS-FR) to examine the reliability, validity, and cross-country invariance of the 9-item version of the Patient Health Questionnaire (PHQ-9) in antenatal s les across eight low- and middle-income countries (LMICs). We found that the PHQ-9 scores had good internal consistency and construct validity across all eight countries. However, in measurement invariance analyses, only partial metric invariance held and only across four of the countries. Further, there were some notable between-site contrasts in the nomological networks of PHQ-9 scores. Our results suggest that the PHQ-9 yields reliable scores when administered in antenatal populations however, the meaning of the scores varies by country. Thus, interpretation of PHQ scores should consider local meanings of depression to ensure that local conceptualisations and manifestations of antenatal depressive symptoms are adequately reflected.

Abstract: Aims This paper explores the number and characterization of latent classes of adverse childhood experiences across the Evidence for Better Lives Study cohort and investigates how the various typologies link to prenatal substance use (i.e., smoking, alcohol, and illicit drugs) and poor infant outcomes (i.e., infant prematurity and low birth weight). Participants and setting A total of 1,189 mother-infant dyads residing in eight erse low- and middle-income countries (LMICs) were recruited. Methods Latent class analysis using the Bolck, Croon, and Hagenaars (BCH) 3-step method with auxiliary multilevel logistic regressions with distal outcomes were performed. Results The LCA identified three high-risk classes and one low-risk class, namely: (1) highly maltreated (7%, n = 89), (2 ) emotionally and physically abused with intra-familial violence exposure (13%, n = 152), (3), emotionally abused (40%, n = 474), and (4) low household dysfunction and abuse (40%, n = 474). Overall, across all latent classes, there were low probabilities of prenatal substance use and poor infant outcomes. However, pairwise comparisons between classes indicate that class 1 and 3 had higher probabilities of prenatal illicit drug use compared to class 4. Additionally, class 2 had higher probability of low birth weight compared to the three remaining classes. Conclusion The results further our understanding of the dynamic and multifaceted nature of ACEs. More research grounded on LMICs is warranted with more attention to various parameters of risk exposure (i.e., severity, duration, chronicity).

Abstract: To date, little attention has been given to prenatal depression, especially in low and middle-income countries. The aim of this research was to assess the prevalence of depression and its associated factors amongst pregnant women in a central Vietnamese city. This cross-sectional study included 150 pregnant women from 29 to 40 weeks of gestation, from eight wards of Hue city, via quota s ling from February to May 2019. We employed the Patient Health Questionnaire (PHQ-9) to assess depression. Findings suggest the need to provide routine screening of pregnant women in primary care for depressive symptoms and other mental health problems.

Abstract: Smoking is considered the most critical modifiable factor with regard to lung cancer and remains a public health concern in many countries, including Vietnam, which is among those countries with the highest tobacco consumption rates in the world. This study has examined the impact of national telephone counselling for smoking cessation and has identified the factors associated with the impact of the quitline among male callers in Vietnam. A randomized cross-sectional survey of 469 smokers who sought smoking cessation services via the national quitline was performed from September 2015 to May 2016. The primary outcomes were measured by a self-reported quit rate at the time of assessment, 7 day point prevalence abstinence (PA), 6 month prolonged PA, service satisfaction, and level of motivation. Among the participants, 31.6% were abstinent, and 5.1% of participants successfully stopped smoking and did not need to seek quitline support. Most of the clients were satisfied with the quality of service (88.5%), felt more confident about quitting (74.3%), and took early action via their first quit attempt (81.7%) 18.3% reported a more than 7 day abstinence period at the time of survey. The primary reasons for smoking relapse were surrounding smoking environments (51.6%) and craving symptoms (44.1%). Future smoking cessation efforts should focus on improving the quality of quitline services, client satisfaction, and developing a tailored program and counseling targeting smokers with specific characteristics, especially ones experiencing chronic diseases.
