Effectiveness of using a patient education mobile application to improve the quality of bowel preparation: a randomised controlled trial.

AIMS: To determine the effectiveness of a mobile application (app) in improving the quality of bowel preparation for colonoscopy. METHOD: An endoscopist-blinded randomised controlled trial enrolled patients who were undergoing a colonoscopy on the same day of bowel preparation. The intervention used a Vietnamese mobile app that provides instructions on bowel preparation while patients in the comparison group received conventional instructions. Outcomes included the Boston Bowel Preparation Scale (BBPS) to assess the quality of bowel preparation and the polyp detection rate (PDR) and adenoma detection rate (ADR). RESULTS: The study recruited 515 patients (256 in the intervention group). The median age was 42 years, 50.9% were females, 69.1% high school graduates and higher, and 45.2% from urban area. Patients in the intervention group had higher adherence to instructions (60.9% vs 52.4%, p=0.05) and longer length of taking laxatives (mean difference 0.17 hours, 95% CI 0.06 to 0.27). The intervention did not reduce the risk of poor bowel cleansing (total BBPS<6) in both overall (7.4% vs 7.7%; risk ratio 0.96, 95% CI 0.53 to 1.76) and subgroup analysis. PDR and ADR were similar between the two groups. CONCLUSIONS: The mobile app providing instructions on proper bowel preparation improved the practice during bowel preparation but did not improve the quality of bowel cleansing or PDR.

Pairwise approach for analysis and reporting of child's free sugars intake from a birth cohort study.

OBJECTIVES: The prospective cohort design is an important research design, but a common challenge is missing data. The purpose of this study is to compare three approaches to managing missing data, the pairwise (n = 1386 children), the partial or modified pairwise (n = 1019) and the listwise (n = 546), to characterize the trajectories of children's free sugars intake (FSI) across early childhood. METHODS: By applying the Group-based Trajectory Model Technique to three waves of data collected from a prospective cohort study of South Australian children, this study examined the three approaches in managing missing data to validate and discuss children's FSI trajectories. RESULTS: Each approach identified three distinct trajectories of child's FSI from 1 to 5 years of age: (1) 'low and fast increasing', (2) 'moderate and increasing' and (3) 'high and increasing'. The trajectory memberships were consistent across the three approaches, and were for the pairwise scenario (1) 15.1%, (2) 68.3% and (3) 16.6%; the partial or modified pairwise (1) 15.9%, (2) 64.1% and (3) 20.0%; and the listwise (1) 14.9%, (2) 64.9% and (3) 20.2% of children. CONCLUSIONS: Given the comparability of the findings across the analytical approaches and the samples' characteristics between baseline and across different data collection waves, it is recommended that the pairwise approach be used in future analyses to optimize the sample size and statistical power when examining the relationship between FSI in the first years of life and health outcome such as dental caries.

Clinical symptoms, endoscopic findings, and lower esophageal sphincter characteristics in patients with absent contractility.

Absent contractility is a rare esophageal motility disorder defined by high-resolution manometry which remains poorly understood in pathogenesis and management. We investigated the clinical symptoms, upper gastrointestinal endoscopy findings, and lower esophageal sphincter (LES) characteristics in adult patients diagnosed with absent contractility on high resolution manometry and factors associated with erosive esophagitis that were found on endoscopy in these patients. A cross-sectional study was conducted in patients with absent contractility who were examined at the Institute of Gastroenterology and Hepatology, Vietnam between March 2018 and December 2020. Clinical symptoms, endoscopic findings, and LES metrics were collected and compared between individuals with and without erosive esophagitis. Logistic regression analysis was used to examine a variety of factors associated with erosive esophagitis. Among 7519 patients who underwent high resolution manometry, 204 (2.7%) were diagnosed with absent contractility. The mean age of the study sample was 45.9 years, 65.7% were women, and none had systemic sclerosis. The most common symptoms were regurgitation, belching, epigastric pain, and bloating. On endoscopy, 50% had erosive esophagitis, mostly Los Angeles grade A (42.9%). On manometry, 44.6% of the patients had LES hypotension and 68.1% had low integrated relaxation pressure in 4 seconds (IRP4s). Male sex (adjusted odds ratio = 2.01, 95% confidence interval: 1.04-3.89) and an IRP4s < 5 mm Hg (adjusted odds ratio = 2.21, 95% confidence interval: 1.12-4.37) were significantly associated with erosive esophagitis. Absent contractility was present in many patients without known systemic diseases. Erosive esophagitis was common and associated with male sex and low IRP4s.

The relationship between team dynamics with healthcare coordination and clinical work satisfaction among Commune Health Workers: A Bayesian model averaging study.

OBJECTIVE: To determine the relationship between team dynamics with healthcare coordination and clinical job satisfaction of the community health workers (CHWs). METHODS: A cross-sectional study was conducted among 133 health workers (including doctors, nurses, or midwives) at 21 Commune Health Cent in Quoc Oai District, Vietnam, from July 2015 to May 2017. A self-administered questionnaire consisting of 5-Likert items regarding team dynamics and healthcare coordination clinical work satisfaction was utilised. Descriptive statistics and correlation matrix were applied for seven factors of team dynamic, clinical work satisfaction, and patient care coordination queried by primary care providers. Bayesian model averaging (BMA) was used to identify the predictors of the level of team dynamics and healthcare coordination. RESULTS: The mean score of overall team dynamics among the study participants was 4.08. Clinical work satisfaction and patient care coordination scores among resident physicians were higher than those of attending clinicians; however, the differences were not statistically significant. The results of BMA analysis indicated that team dynamics significantly associated with clinical work satisfaction, and it explains 9% of the total variance in clinical work satisfaction. Team dynamics level was also positively associated with patient care coordination. Patient care coordination was not a significant mediator between team dynamics and clinical work satisfaction. CONCLUSION: Team dynamics is a potential contributor to improving patient care coordination and clinical job satisfaction of CHWs. As no significant correlation between patient care coordination and clinical job satisfaction was observed, to improve team performance, providing conditions that facilitate team building and teamwork should be conducted for CHWs in CHCs.

Group-based trajectories of maternal intake of sugar-sweetened beverage and offspring oral health from a prospective birth cohort study.

OBJECTIVES: To investigate the trajectory of maternal intake of sugar-sweetened beverages (SSB) during the first five years of their child's life and its effect on the child's dental caries at five years-of-age. METHODS: This is an ongoing prospective population-based birth cohort study in Adelaide, Australia. Mothers completed questionnaires on their SSB intake, socioeconomic factors and health behaviors at the birth of their child and at the ages of one, two and five years. Child dental caries measured as decayed, missing, or filled tooth surfaces was collected by oral examination. Maternal SSB intake was used to estimate the trajectory of SSB intake. The trajectories then became the main exposure of the study. Dental caries at age five years were the primary outcomes. Adjusted mean- and prevalence-ratios were estimated for dental caries, controlling for confounders. RESULTS: 879 children had dental examinations at five years-of-age. Group-based trajectory modeling identified three trajectories of maternal SSB intake: 'Stable low' (40.8%), 'Moderate but increasing' (13.6%), and 'High early' trajectory (45.6%). Multivariable regression analysis found children of mothers in the 'High early' and 'Moderate but increasing' groups to have greater experience of dental caries (MR: 1.37 (95%CI 1.01-1.67), and 1.24 (95%CI 0.96-1.60) than those in the 'Stable low' trajectory, respectively. CONCLUSION: Maternal consumption of SSB during pregnancy and in the early postnatal period influenced their offspring's oral health. It is important to create a low-sugar environment from early childhood. The results suggest that health promotion activities need to be delivered to expecting women or soon after childbirth.

Translation, validation and psychometric properties of Effort-Reward Imbalance questionnaire among nurses in Vietnam.

We translated the Effort-Reward imbalance questionnaire, an instrument for measuring work stress, into the Vietnamese language and investigated its psychometric properties among nurses in Vietnam. In a hospital-based cross-sectional study design, we sampled and interviewed 207 nurses working full-time (response rate 83%). We evaluated the internal consistency using standardized Cronbach's alpha coefficients and structural validity using confirmatory factor analysis. Discriminative validity was assessed by comparing the measured scores between age groups, gender, education levels, income groups, and job positions. In addition, we confirmed the criterion validity by investigating its association with self-reported health using simple and multiple logistic regression models. Most of the participants were female (73.3%), young (average 28.5 years old), and had education levels of college or higher (53.5%). We observed sufficient internal consistency in effort, reward, and over-commitment scales (Cronbach's alpha 0.80, 0.76, and 0.68, respectively). Confirmatory factor analysis of the three-factor hierarchical model showed an acceptable fit and fair construct validity with most moderate or stronger (>0.3) factor loading coefficients. Poor self-rated health was more likely in respondents in both Effort-Reward ratio's middle tertile (adjusted Odd-Ratio = 2.80, p-value = 0.031) and highest tertile (adjusted Odd-Ratio = 2.64, p-value = 0.05), adjusting for age, gender, and education levels. The Effort-reward imbalance scale has adequate reliability and validity for assessing work stress among nurses in Vietnam. Its significant association with poor self-rated health warrants further investigation. The validated instrument can help measure the effort-reward imbalance to manage better work-related emotional strains and mental health issues among nurses and ensure human resources' stability in healthcare in Vietnam.

The COVID-19 pandemic in Australia: Public health responses, opportunities and challenges.

In responding to the COVID-19 pandemic, each country is presented with both opportunities and challenges, some unique and some shared with the global community. It is important to not only recognize, but to embrace them as drivers of the public to the current pandemic success. In this commentary, we discuss the opportunities and challenges that may affect ongoing public health programming in Australia within the current context of epidemiology. COVID-19 within Australia has to date been effectively suppressed through the implementation of nationally coordinated, in which the state delivered public policy, guidelines and practice, and successful establishment of a comprehensive testing, contact tracing, patient isolation and contact quarantine regime combined with national and state social distancing, hygiene etiquette and movement restrictions. However, despite its success to date great challenges lay ahead for future public health policy with the threat of a second wave, or more likely, multiple smaller outbreaks across various population centres. Therefore, policies that aim to balance the twin socioeconomic and health impacts are crucial. The experience of Australia in managing its COVID-19 response can provide a case study for other countries to reshape or adapt their policies and actions in the context of emerging global health crises.

Trends in, projections of, and inequalities in reproductive, maternal, newborn and child health service coverage in Vietnam 2000-2030: A Bayesian analysis at national and sub-national levels.

BACKGROUND: To assess the reproductive, maternal, newborn and child health (RMNCH) service coverage in Vietnam with trends in 2000-2014, projections and probability of achieving targets in 2030 at national and sub-national levels; and to analyze the socioeconomic, regional and urban-rural inequalities in RMNCH service indicators. METHODS: We used national population-based datasets of 44,624 households in Vietnam from 2000 to 2014. We applied Bayesian regression models to estimate the trends in and projections of RMNCH indicators and the probabilities of achieving the 2030 targets. Using the relative index, slope index, and concentration index of inequality, we examined the patterns and trends in RMNCH coverage inequality. FINDINGS: We projected that 9 out of 17 health service indicators (53%) would likely achieve the 2030 targets at the national level, including at least one and four ANC visits, BCG immunization, access to improved water and adequate sanitation, institutional delivery, skilled birth attendance, care-seeking for pneumonia, and ARI treatment. We observed very low coverages and zero chance of achieving the 2030 targets at national and sub-national levels in early initiation and exclusive breastfeeding, family planning needs satisfied, and oral rehydration therapy. The most deprived households living in rural areas and the Northwest, Northeast, North Central, Central Highlands, and Mekong River Delta regions would not reach the 80% immunization coverage of DPT3, Polio3, Measles and full immunization. We found socioeconomic, regional, and urban-rural inequalities in all RMNCH indicators in 2014 and no change in inequalities over 15 years in the lowest-coverage indicators. INTERPRETATION: Vietnam has made substantial progress toward UHC. By improving the government's health system reform efforts, re-allocating resources focusing on people in the most impoverished rural regions, and restructuring and enhancing current health programs, Vietnam can achieve the UHC targets and other health-related SDGs. FUNDING: The authors did not receive any funds for conducting this study.

Adherence to highly active antiretroviral therapy among people living with HIV and associated high-risk behaviours and clinical characteristics: A cross-sectional survey in Vietnam.

Although Vietnam has promoted the utilisation of highly active antiretroviral therapy (HAART) towards HIV elimination targets, adherence to treatment has remained under-investigated. We aimed to describe high-risk behaviours and clinical characteristics by adherence status and to identify the factors associated with non-adherence. We included 426 people living with HIV (PLWH) currently or previously involved in HAART. Most participants were men (75.4%), young (33.6 years), with low income and low education levels. Non-adherent PLWH (11.5%) were more likely to have a larger number of sex partners (p-value = 0.053), sex without condom use (p-value = 0.007) and not receive result at hospital or voluntary test centre (p-value = 0.001). Multiple logistic regression analysis showed that demographic (education levels), sexual risk behaviours (multiple sex partners and sex without using condom) and clinical characteristics (time and facility at first time received HIV-positive result) were associated with HAART non-adherence. There are differences in associated factors between women (education levels and place of HIV testing) and men (multiple sex partners). Gender-specific programs, changing risky behaviours and reducing harms among PLWH may benefit adherence. We highlight the need to improve the quantity and quality of HIV/AIDS services in Vietnam, especially in pre- and post-test counselling, to achieve better HAART adherence, working towards ending AIDS in 2030.

Changes in, and predictors of, quality of life among patients with unstable angina after percutaneous coronary intervention.

RATIONALE, AIMS AND OBJECTIVES: Changes in, and predictors of, quality of life (QoL) among unstable angina patients are informative for both clinical and public health practice. However, there is little research on this topic, especially in health care settings with limited resources. This study aims to detect changes in QoL and its associated factors among patients with unstable angina after percutaneous coronary intervention. METHODS: A longitudinal design was conducted with two repeated rounds of measurements, 1 and 3 months after intervention, using the generic SF-36 questionnaire, in 120 patients from Vietnam National Heart Institute. A linear mixed-effects model was used to assess changes in patient QoL over time while adjusting for other covariates. RESULTS: Only two out of eight QoL subscales (social functioning and emotional well-being) declined after 1 month, but these tended to rise again after 3 months, while scores of all other QoL subscales increased. Adjusting for covariates, QoL increased slightly after 1 month of intervention (ß = 0.65, 95%CI = -0.86 to 2.16) but improved by almost six QoL points after 3 months (ß = 5.99, 95%CI = 4.48 to 7.50). Four confounders significantly associated with a decline in QoL were older age, being retired, living in rural areas, and having abnormal troponin level. CONCLUSION: QoL of the patients with unstable angina improves significantly 3 months after intervention, rather than after 1 month. More attention should be given to patients, who are old, retired, live in rural areas and have abnormal troponin level.

Comparing a standard and tailored approach to scaling up an evidence-based intervention for antiretroviral therapy for people who inject drugs in Vietnam: study protocol for a cluster randomized hybrid type III trial.

BACKGROUND: People who inject drugs (PWID) bear a disproportionate burden of HIV infection and experience poor outcomes. A randomized trial demonstrated the efficacy of an integrated System Navigation and Psychosocial Counseling (SNaP) intervention in improving HIV outcomes, including antiretroviral therapy (ART) and medications for opioid use disorder (MOUD) uptake, viral suppression, and mortality. There is limited evidence about how to effectively scale such intervention. This protocol presents a hybrid type III effectiveness-implementation trial comparing two approaches for scaling-up SNaP. We will evaluate the effectiveness of SNaP implementation approaches as well as cost and the characteristics of HIV testing sites achieving successful or unsuccessful implementation of SNaP in Vietnam. METHODS: Design: In this cluster randomized controlled trial, two approaches to scaling-up SNaP for PWID in Vietnam will be compared. HIV testing sites (n = 42) were randomized 1:1 to the standard approach or the tailored approach. Intervention mapping was used to develop implementation strategies for both arms. The standard arm will receive a uniform package of these strategies, while implementation strategies for the tailored arm will be designed to address site-specific needs. PARTICIPANTS: HIV-positive PWID participants (n = 6200) will be recruited for medical record assessment at baseline; of those, 1500 will be enrolled for detailed assessments at baseline, 12, and 24 months. Site directors and staff at each of the 42 HIV testing sites will complete surveys at baseline, 12, and 24 months. OUTCOMES: Implementation outcomes (fidelity, penetration, acceptability) and effectiveness outcomes (ART, MOUD uptake, viral suppression) will be compared between the arms. To measure incremental costs, we will conduct an empirical costing study of each arm and the actual process of implementation from a societal perspective. Qualitative and quantitative site-level data will be used to explore key characteristics of HIV testing sites that successfully or unsuccessfully implement the intervention for each arm. DISCUSSION: Scaling up evidence-based interventions poses substantial challenges. The proposed trial contributes to the field of implementation science by applying a systematic approach to designing and tailoring implementation strategies, conducting a rigorous comparison of two promising implementation approaches, and assessing their incremental costs. Our study will provide critical guidance to Ministries of Health worldwide regarding the most effective, cost-efficient approach to SNaP implementation.

Healthcare Workers' Knowledge and Attitudes Regarding the World Health Organization's "My 5 Moments for Hand Hygiene": Evidence From a Vietnamese Central General Hospital.

OBJECTIVES: Although the World Health Organization (WHO) initiative "My 5 Moments for Hand Hygiene" has been lauded as effective in preventing hospital-associated infections, little is known about healthcare workers (HCWs)' hand hygiene behavior. In this study, we sought to assess knowledge and attitudes towards the concepts in this initiative, as well as associated factors, among Vietnamese HCWs at a general hospital. METHODS: A structured questionnaire was administered to HCWs at a central Vietnamese general hospital in 2015. Multiple logistic regression analysis was used to identify factors associated with HCWs' knowledge and attitudes towards hand hygiene. RESULTS: Of 120 respondents, 65.8% and 67.5% demonstrated appropriate knowledge and a positive attitude, respectively, regarding all 5 hand hygiene moments. Logistic regression indicated better knowledge of hand hygiene in workers who were over 30 years old, who were direct HCWs (rather than managers), who had frequent access to clinical information, and who received their clinical information from training. Those who worked in infectious and tropical disease wards, who had frequent access to clinical information, and who received information from training were more likely to have a positive attitude towards hand hygiene than their counterparts. CONCLUSIONS: Although many Vietnamese HCWs displayed moderate knowledge and positive attitudes towards the WHO hand hygiene guidelines, a key gap remained. Regular education and training programs are needed to increase knowledge and to improve attitudes and practices towards hand hygiene. Furthermore, a combination of multimodal strategies and locally-adapted interventions is needed for sustainable hand hygiene adherence.

An adaptive model of health system organization and responses helped Vietnam to successfully halt the Covid-19 pandemic: What lessons can be learned from a resource-constrained country.

Coping with the COVID-19 pandemic has been painful and no single model for such a purpose is perfect. However, sharing experiences is the best way for countries to learn real-time lessons and adapt to this rapidly changing pandemic. This commentary shares with the international community how an adaptive model of health system organization and responses helped Vietnam to break transmission of coronavirus. We find that an effective model is adaptive to time and context, and mobilizes and engages the wider society. We identify merging of different health system units into Center for Diseases Controls as a health system organization that saved massive resources. The early establishment of a formal committee responding to the pandemic helped unify every public health strategy. The mobilization of different stakeholders and communities added resources and facilitated a synchronous implementation of response strategies, even where those strategies involved significant personal or financial sacrifice. National training on Covid-19 treatment for healthcare professionals across the entire hospital system was useful to expand the health service availability. Quickly published response guidelines helped to activate every level of the health system and involve every sector of society. A strategy of keeping high alert and preemptive action is also essential for coping with the pandemic.

Human adipose-derived mesenchymal stem cells for acute and sub-acute TBI.

In the U.S., approximately 1.7 million people suffer traumatic brain injury each year, with many enduring long-term consequences and significant medical and rehabilitation costs. The primary injury causes physical damage to neurons, glia, fiber tracts and microvasculature, which is then followed by secondary injury, consisting of pathophysiological mechanisms including an immune response, inflammation, edema, excitotoxicity, oxidative damage, and cell death. Most attempts at intervention focus on protection, repair or regeneration, with regenerative medicine becoming an intensively studied area over the past decade. The use of stem cells has been studied in many disease and injury models, using stem cells from a variety of sources and applications. In this study, human adipose-derived mesenchymal stromal cells (MSCs) were administered at early (3 days) and delayed (14 days) time points after controlled cortical impact (CCI) injury in rats. Animals were routinely assessed for neurological and vestibulomotor deficits, and at 32 days post-injury, brain tissue was processed by flow cytometry and immunohistochemistry to analyze neuroinflammation. Treatment with HB-adMSC at either 3d or 14d after injury resulted in significant improvements in neurocognitive outcome and a change in neuroinflammation one month after injury.

Cardiac dysregulation following intrahippocampal kainate-induced status epilepticus.

Status epilepticus (SE) is a prevalent disorder associated with significant morbidity, including the development of epilepsy and mortality. Cardiac arrhythmias (i.e. inappropriate sinus tachycardia and bradycardia, asystole, and atrioventricular blocks) are observed in patients following SE. We characterized ictal (during a seizure) and interictal (between seizure) cardiac arrhythmogenesis following SE using continuous electrocardiography and video electroencephalography (vEEG) recordings throughout a 14-day monitoring period in an intrahippocampal chemoconvulsant mouse model that develops epilepsy. We quantified heart rhythm abnormalities and examined whether the frequency of cardiac events correlated with epileptiform activity, circadian (light/dark) cycle, the presence of seizures, and survival during this period of early epileptogenesis (the development of epilepsy) following SE. Shortly following SE, mice developed an increased interictal heart rate and heart rhythm abnormalities (i.e. sinus pause and sinus arrhythmias) when compared to control mice. Heart rhythm abnormalities were more frequent during the light cycle and were not correlated with increased epileptiform activity or seizure frequency. Finally, SE animals had early mortality, and a death event captured during vEEG recording demonstrated severe bradycardia prior to death. These cardiac changes occurred within 14 days after SE and may represent an early risk factor for sudden death following SE.

Stewartiacids A-N, C-23 carboxylated triterpenoids from Chinese Stewartia and their inhibitory effects against ATP-citrate lyase and NF-κB.

Fourteen previously undescribed naturally occurring C-23 carboxylated triterpenoids, stewartiacids A-N (1-14), were isolated and characterized from the twigs and leaves of the ornamental and medicinal plant Stewartia sinensis (Chinese Stewartia), a 'vulnerable' species endemic to China. The new structures were elucidated on the basis of spectroscopic data, single crystal X-ray diffraction, and electronic circular dichroism (ECD) analyses. Stewartiacids A (1) and B (2) are isoursenol derivatives. Stewartiacid C (3) is a 12-oxo-γ-amyrin analogue. Both isoursenol and γ-amyrin derivatives are quite rare in nature. Stewartiacids D (4) and E (5) are 13,27-cycloursane-type compounds. Stewartiacids K (11) and L (12) are ursane-type triterpene and phenylpropanol adducts built through a 1,4-dioxane ring, which are also seldom reported in the literature. The rest are common C-23 carboxylated ursane-type (6-10) and oleanane-type (13, 14) pentacyclic triterpenoids. Stewartiacids G (7), K (11), and L (12) showed moderate inhibitory effects against ATP-citrate lyase (ACL), with IC50 values of 12.5, 2.8, and 10.6 µM, respectively. Stewartiacid K (11) also exhibited moderate inhibition (IC50: 16.8 µM) of NF-κB.

Stakeholder Engagement in Late-Stage Translation Phase 4 Research for Noncommunicable Diseases in Low- and Middle-Income Countries: What Works and Why-The Vietnam Experience (UMMS-Vietnam Team).

BACKGROUND: Stakeholder engagement is crucial for conducting high-quality implementation research as well as for the incorporation and adoption of health interventions and policies in the community. OBJECTIVES: This study sought to build a mutually rewarding collaboration between stakeholders in Vietnam and investigators in the United States. METHODS: A collaboration was established between investigators from several institutions in Vietnam and the University of Massachusetts Medical School that was built on mutual trust, cross-cultural learning, and shared experiences. This collaborative arrangement has led to sustainable stakeholder engagement in Vietnam. We formed a multidisciplinary transnational research team and maintained regular contact both online and in person. We also conducted a needs assessment study, in which several focus group discussions and in-depth interviews of stakeholders in Vietnam were carried out. RESULTS: The formal collaboration between investigators in Vietnam and the University of Massachusetts Medical School began in 2011 and has strengthened over time. The U.S. team provided expertise in study and intervention design, data collection and analysis, and trial implementation, whereas the team in Vietnam brought a deep understanding of local health care delivery systems and expertise in the delivery of health care interventions at the grassroots level. Our initial partnership has now grown to include committed individuals at the government, academic, and community levels including the Vietnam Ministry of Health, key governmental and nongovernmental research institutions and agencies, medical and public health universities, and communities in rural settings. The needs assessment study found that there are important gaps in the delivery of hypertension management practices in many rural communities in Vietnam and that stakeholders are fully engaged in our ongoing, community-based, hypertension-control project. CONCLUSIONS: Multiple layers of stakeholders and communities in Vietnam are fully engaged with, and have contributed significantly to, our ongoing hypertension control research project in Northern Vietnam.

Knowledge and Determinants of Health Consequences of Cigarette Smoking Among Vietnamese Adults, 2015.

Background. Vietnam was one of 16 countries that implemented the second round of the GATS (Global Adult Tobacco Survey) in 2015. Aims. To assess knowledge and determinants of health consequences of different types of cigarette smoking among Vietnamese adults. Methods. A cross-sectional study among adults aged 15 years combined with using 15% of the master sample from the national sampling frame of the population and housing census was conducted. Multilevel analysis using Poisson regression was undertaken. Results. Knowledge on the health consequences of cigarette smoking has not significantly improved in the GATS-2015. Adults believe that active smoking had more of an impact on health than secondhand smoking and 24.5% and 43% of them answered that smoking light and e-cigarettes, respectively, causes less harm than regular cigarettes, and 17.3% and 18.1% of adults are not aware of the difference between them, respectively. Conclusion. Household and community's role had little impact in the adult knowledge of smoking health consequences. It is necessary to disseminate information on the "other tobacco product" and to improve public knowledge on specific health consequences, to enhance household and community's role in conveying health education messages to individuals.
