Abstract: Aim . Diabetes in children is becoming more prevalent in some countries. However, in most countries, little is known about the epidemiology of this disease. This study is aimed at estimating the prevalence of type 1 and type 2 diabetes and prediabetes among children in Vietnam and examining factors associated with the conditions. Methods . A total of 2880 students aged 11-14 years old were recruited for the survey, using a school-based and nationally representative s ling frame. Capillary blood s les of participants were collected to measure fasting glucose level, using glucose meter OneTouch Verio Pro+. Diabetes and impaired fasting plasma glucose were initially diagnosed based on the cut-off points of the American Diabetes Association criteria. Diabetes status and type of diabetes of participants were confirmed at a hospital. Additionally, anthropometric and blood pressure measurements were conducted following a standardized procedure. Multivariate logistic regression was used to examine the association between outcome and independent variables. Results . The overall prevalence of diabetes among the participants was 1.04‰ (three cases), with 2 cases (0.75‰) diagnosed with type 1 diabetes (one known and one newly diagnosed) and 1 case newly diagnosed with type 2 diabetes (0.35‰). The prevalence of impaired fasting glucose was 6.1%. Body mass index, place of residence, and age were found to be significantly associated with the impaired fasting glucose condition in participants. Conclusion . The prevalence of type 1 and type 2 diabetes in children in Vietnam is lower than that in some other countries reported recently. However, there is a high prevalence in impaired fasting glucose, requiring attention from policymakers to take action to prevent the occurrence of the epidemic of type 2 diabetes in children in the future.

Abstract: The issue of causation is one of the major challenges for epidemiologists who aim to understand the association between an exposure and an outcome to explain disease patterns and potentially provide a basis for intervention. Suitably designed experimental studies can offer robust evidence of the causal relationships. The experimental studies, however, are not popular, difficult or even unethical and impossible to conduct it would be desirable if there is a methodology for reducing bias or strengthening the causal inferences drawn from observational studies. The traditional approach of estimating causal effects in such studies is to adjust for a set of variables judged to be confounders by including them in a multiple regression. However, which variables should be adjusted for as confounders in a regression model has long been a controversial issue in epidemiology. From my observation, the adjustments using only "statistical artifacts" methods such as the p-value .2 in univariate analysis, stepwise (forward/backward) are widely used in research and teaching in Epidemiology and Statistics but without appropriated notice on the biological or clinical relationships between exposure and outcome which may induce the bias in estimating causal effects. In this mini-review, we introduce an interesting method, namely Directed Acyclic Graphs (DAGs), which can be used to reduce the bias in estimating causal effects it is also a good application for Epidemiology and Biostatistics teaching.

Abstract: Smoking leads to many smoking-attributable diseases. The promotion of quitting tobacco smoking is urgent as it has significant and immediate health benefits and improves the impacts of other tobacco control strategies. Intention to quit smoking is considered the first step before quitting smoking. This paper used data from Vietnam provincial GATS 2020 on 80,166 participants who were 15-year-old or older. Data were collected from 34 provinces and cities throughout Vietnam and managed using REDCap. Among those who were current smokers, 50.3% (95% CI: 49.1%–51.4%) had the intention to quit smoking. Some predictive factors found to be positively associated with the intention to quit smoking were age (from 45-64), education level, received information about harmful effects or encouragement to quit smoking from media channels (from 6 channels), hearing about the Tobacco Control Law and noticing health warnings on the cigarette package. There was no significant difference in intention to quit smoking between current smokers from urban and rural areas or among different age groups to start smoking. Interventions or health promotion programs on smoking cessation should be focused on current smokers who have low education levels as they have a higher smoking rate and are less motivated to stop smoking. Received information about harmful effects or encouragement to quit smoking from media channels is also associated with stopping smoking in the future. The importance of health warning pictures on tobacco packages should be maintained and promoted as it has a specific effect on one’s intention to stop smoking.

Abstract: This study investigates the prevalence of tobacco and alcohol uses and associated factors among 12 ethnic minorities in Vietnam in 2019. A cross-sectional survey was conducted among 5172 people aged ≥15 years. The prevalence of smoking and drinking was 19.7% and 29.9%, respectively, and significantly higher among men than women. These numbers were heterogeneous across ethnic minorities. Smoking prevalence was high among Ba Na (25.9%), Cham An Giang (22.3%), Khmer (23.5%), La Hu (26.3%), Ta Oi (30.7%), and Bru Van Kieu (29.6%) ethnicities whereas that of Gie Trieng and Mnong ethnicities was low (3.7% and 9.5%, respectively). Drinking prevalence ranged from 1.4% in Cham An Giang ethnicity to 68.6% in Ba Na ethnicity. A wide ethnic disparity on tobacco and alcohol use could be explained by the ethnic variation of lifestyles, social norms, and cultural features. Our findings suggest the need to develop ethnic-specific interventions to mitigate the smoking and drinking prevalence.

Abstract: Previous studies have observed lower utilization of maternal healthcare services by ethnic minority groups in Vietnam compared with the majority Kinh community. This study sought to assess the utilization of maternal healthcare service-associated factors within 12 ethnic minority groups. The cross-sectional study enrolled 996 women from 12 ethnic minority groups in Vietnam in 2019. Women had pregnancy outcomes in the last 5 years. The two variables for maternal healthcare utilization were [1] a minimum of four antenatal contacts and [2] health facility-based delivery. We examined the association of in idual characteristics of maternal healthcare services using multilevel modeling. Odds ratios (ORs) and 95% confidence intervals (CIs) were reported. This nationally representative study found that 34.1% of women from ethnic minority backgrounds had four or more antenatal contacts during pregnancy, ranging from 8.3% in Mong community to 80.2% in Cham An Giang. Most of the women (94.4%) delivered at health facilities. Factors independently correlated with having fewer than four antenatal contacts included being illiterate, early marriage, unemployment, religious affiliation, household economy, and distance to the nearest health facility. Factors significantly associated with home delivery were living in the most disadvantaged areas and having fewer than four antenatal contacts. Substantial inequity exists in antenatal coverage both within ethnic minority groups and between socio-economic groups. The low coverage of having at least four antenatal contacts and its' correlates with facility-based delivery suggests that the government should focus efforts on increasing the number of antenatal contacts for ethnic minority women.

Abstract: Tobacco smoking is one of the most dangerous risk behaviors, leading to many adverse human health consequences. The aims of this study is to estimate the prevalence of tobacco smoking and related factor among adolescents aged 13–17 years in Vietnam. The data were from two rounds of the Vietnam Global School-based Student Health Survey (GSHS) that is the nationally representative survey conducted in 2013 and 2019. The logistic regressions were carried out to identify factors associated with tobacco smoking among study participants. We found the prevalence of current smoking (water pipe and cigarettes) reduced significantly from 5.4% (95% CI: 4.0–7.2) in 2013 to 2.8% (95% CI: 2.2–3.6) in 2019. In 2019, 2.6% of students used electronic cigarette products in the last 30 days. Factors associated with higher odds of current smoking status included study year, gender, parental monitoring, loneliness, suicide attempt, sexual intercourse, truancy, alcohol drinking. Similar patterns were found in e-cigarette use. Smoking among adolescents in Vietnam reduced between 2013 and 2019. Further follow-up studies are needed to confirm the causal factors of the reduction and e-cigarettes use.

Abstract: From 1985 to 2016, the prevalence of underweight decreased, and that of obesity and severe obesity increased, in most regions, with significant variation in the magnitude of these changes across regions. We investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-based studies with 187 million participants. Changes in the prevalence of underweight and total obesity, and to a lesser extent severe obesity, are largely driven by shifts in the distribution of BMI, with smaller contributions from changes in the shape of the distribution. In East and Southeast Asia and sub-Saharan Africa, the underweight tail of the BMI distribution was left behind as the distribution shifted. There is a need for policies that address all forms of malnutrition by making healthy foods accessible and affordable, while restricting unhealthy foods through fiscal and regulatory restrictions.

Abstract: Adolescent birth is a major global concern owing to its adverse effects on maternal and child health. We assessed trends in adolescent birth and examined its associations with child undernutrition in Bangladesh using data from seven rounds of Demographic and Health Surveys (1996–2017, n = 12,006 primiparous women with living children years old). Adolescent birth (10–19 years old) declined slowly, from 84% in 1996 to 71% in 2017. Compared with adult mothers (≥20 years old), young adolescent mothers (10–15 years old) were more likely to be underweight (+11 pp), have lower education (−24 pp), have less decision‐making power (−10 pp), live in poorer households (−0.9 SD) with poorer sanitation (−15 pp), and have poorer feeding practices (10 pp), and were less likely to access health and nutrition services (−3 to −24 pp). In multivariable regressions controlled for known determinants of child undernutrition, children born to adolescents had lower height‐for‐age Z‐scores (−0.29 SD for young and −0.10 SD for old adolescents (16–19 years old)), weight‐for‐age Z‐score (−0.18 and −0.06 SD, respectively) as well as higher stunting (5.9 pp) and underweight (6.0 pp) than those born to adults. In conclusion, birth during adolescence, a common occurrence in Bangladesh, is associated with child undernutrition. Policies and programs to address poverty and improve women's education can help delay marriage, reduce early childbearing, and improve child growth.

Abstract: Electronic cigarette use among adolescents has increased in the past decade. Little is known about the perception and use of e-cigarettes in Vietnam, especially among young people. This study examines the perceptions and use of electronic cigarettes among young adults in Vietnam. The study uses data from a survey of adult tobacco consumption among adults at the provincial level in 2020, which was funded and managed by the Vietnam Tobacco Control Fund-Ministry of Health. Data were collected from 34 provinces and cities throughout Vietnam and managed using REDCap software. The survey engaged 80,166 participants, of which 9478 were young adults aged 15-24 were selected and reported in this paper. The results show that, at the time of the survey, 2.4% of young Vietnamese adults were smoking e-cigarettes. Many survey participants cited more than one reason for smoking e-cigarettes. These reasons included preferring the taste of e-cigarettes (64.0%), disliking the odour of other cigarettes (46.2%), following the ex le of family members (44.9%), and believing e-cigarettes threatened fewer health risks (39.1%). Almost half of the e-cigarette users wanted to quit (48%). E-cigarette use was associated with males living in urban areas who are aware of the Law on Prevention and Control of Tobacco Harms. The findings of this study provide evidential data that support public health policies aimed at reducing and ceasing e-cigarette use among young people.

Abstract: The objective of this study was to determine the prevalence of hetamine-type stimulant use and associated factors among methadone maintenance treatment (MMT) patients. In 2018, a cross-sectional study was conducted on 967 MMT patients at two methadone clinics in Ho Chi Minh City that serve Vietnamese patients. Amphetamine-type stimulant use was assessed by rapid urine test and face-to-face interview using the Alcohol, Smoking, Substance Involvement Screening Test (ASSIST) tool. The prevalence of hetamine-type stimulant use assessed by urine test was 25.4%. According to ASSIST, the prevalence of moderate and high risk hetamine-type stimulant use was 15.5% and 1.1%, respectively. Amphetamine-type stimulant use and hazardous use were more prevalent in younger patients, having a part-time job, drug injection, having a lower score of self-health assessment, treated with a higher dose of methadone and missing methadone dose in the past 3 months. By contrast, patients who were HIV positive were less likely to use hetamine-type stimulants. Cannabis and heroin use were significantly associated with hetamine-type stimulant use (OR = 1.46 95% CI: 1.38-8.67 and OR = 1.50 CI: 1.04-2.18, respectively) and hazardous use (OR = 4.07 CI: 1.67-9.92 and OR = 2.38 CI: 1.56-3.63, respectively). Screening and interventions are needed to cope with this issue on time, particularly in young patients, having drug injection and concurrent drugs user groups.

Abstract: Background Adolescence is a vulnerable period for many lifestyle risk behaviors. In this study, we aimed to 1) examine a clustering pattern of lifestyle risk behaviors 2) investigate roles of the school health promotion programs on this pattern among adolescents in Vietnam. Methods We analyzed data of 7,541 adolescents aged 13-17 years from the 2019 nationally representative Global School-based Student Health Survey, conducted in 20 provinces and cities in Vietnam. We applied the latent class analysis to identify groups of clustering and used Bayesian 2-level logistic regressions to evaluate the correlation of school health promotion programs on these clusters. We reassessed the school effect size by incorporating different informative priors to the Bayesian models. Findings The most frequent lifestyle risk behavior among Vietnamese adolescents was physical inactivity, followed by unhealthy diet, and sedentary behavior. Most of students had a cluster of at least two risk factors and nearly a half with at least three risk factors. Latent class analysis detected 23% males and 18% females being at higher risk of lifestyle behaviors. Consistent through different priors, high quality of health promotion programs associated with lower the odds of lifestyle risk behaviors (highest quality schools vs. lowest quality schools males: Odds ratio (OR) = 0.67, 95% Highest Density Interval (HDI): 0.46 - 0.93 females: OR = 0.69, 95% HDI: 0.47 - 0.98). Interpretation Our findings demonstrated the clustering of specific lifestyle risk behaviors among Vietnamese in-school adolescents. School-based interventions separated for males and females might reduce multiple health risk behaviors in adolescence.

Abstract: Achieving access to clean water and basic sanitation remains as major challenges in Vietnam, especially for vulnerable groups such as minority people, despite all the progress made by the Millennium Development Goal number 7.C. The study aimed to describe the access to improved water sources and sanitation of the ethnic minority people in Vietnam based on a national survey and to identify associated factors. A cross-sectional study was conducted in 2019 with a s le size of 1385 ethnic minority households in 12 provinces in Vietnam. Multivariate logistic regression modeling was performed to examine the probability of having access to improved water sources and sanitation and sociodemographic status at a significance level of P .05. The access to improved water sources and sanitation was unequal among the ethnic minority people in Vietnam, with the lowest access rate in the northern midland and mountainous and Central Highland areas and the highest access rate in the Mekong Delta region. Some sociodemographic variables that were likely to increase the ethnic minority people’s access to improved water sources and/or sanitation included older age, female household heads, household heads with high educational levels, religious households, and households in not poor status. The study suggested more emphasis on religion for improving the ethnic minority’s access to improved water sources and sanitation. Besides, persons of poor and near-poor status and with low educational levels should be of focus in future water and sanitation intervention programs.

Abstract: School violence and injury are major public health problems worldwide. The data of this study were from the Viet Nam Global School-based Student Health Survey (GSHS) - a nationally representative survey conducted in 2019, with a s le size of 7690 students aged 13-17 years old. We found the prevalence of violence and non-fatal injury to be 14.5% and 21.4%, respectively. Factors related to higher odds of violence and non-fatal injuries in both sexes included smoking cigarettes, drinking alcohol, having mental health problems (loneliness, worrying and suicidal thinking), and truancy. In contrast, parental monitoring was associated with lower odds of violence, and parental respect was a protective factor of both violence and non-fatal injuries. Students who experienced violence had a higher likelihood of having non-fatal injuries in both sexes. Future policies should consider in idual factors and parent-child bonding, to mitigate the burden of violence and injury among in-school adolescents in Viet Nam.
