Effectiveness of community-based diabetes and hypertension prevention and management programmes in Indonesia and Viet Nam: a quasi-experimental study.

INTRODUCTION: Non-communicable diseases (NCDs) have surpassed infectious diseases as the leading global cause of death, with the Southeast Asian region experiencing a significant rise in NCD prevalence over the past decades. Despite the escalating burden, screening for NCDs remains at very low levels, resulting in undetected cases, premature mortality and high public healthcare costs. We investigate whether community-based NCD prevention and management programmes are an effective solution. METHODS: In Indonesia, we compare participants in the community-based NCD screening and management programme Pos Pembinaan Terpadu-Penyakit Tidak Menular with matched non-participants with respect to their uptake of screening activities, health-related behaviour and knowledge and metabolic risk factors. We use statistical matching to redress a possible selection bias (n=1669). In Viet Nam, we compare members of Intergenerational Self-Help Clubs, which were offered similar NCD health services, with members of other community groups, where such services were not offered. We can rely on two waves of data and use a double-difference approach to redress a possible selection bias and to measure the impacts of participation (n=1710). We discuss strengths and weaknesses of the two approaches in Indonesia and Viet Nam. RESULTS: In Indonesia, participants have significantly higher uptake of screening for hypertension and diabetes (+13% from a control mean of 88% (95% CI 9% to 17%); +93% from a control mean of 48% (95% CI 79% to 108%)). In both countries, participants show a higher knowledge about risk factors, symptoms and complications of NCDs (Indonesia: +0.29 SD (0.13-0.45), Viet Nam: +0.17 SD (0.03-0.30)). Yet, the improved knowledge is only partly reflected in improved health behaviour (Viet Nam: fruit consumption +0.33 SD (0.15-0.51), vegetable consumption +0.27 SD (0.04-0.50)), body mass index (BMI) (Viet Nam: BMI -0.07 SD (-0.13 to -0.00)) or metabolic risk factors (Indonesia: systolic blood pressure: -0.13 SD (-0.26 to -0.00)). CONCLUSION: Community-based NCD programmes are well suited to increase screening and to transmit health knowledge. Due to their extensive outreach within the community, they can serve as a valuable complement to the screening services provided at the primary healthcare level. Yet, limited coverage, insufficient resources and a high staff turnover remain a problem. TRIAL REGISTRATION NUMBER: NCT05239572.

Associations between gaming disorder, parent-child relationship, parental supervision, and discipline styles: Findings from a school-based survey during the COVID-19 pandemic in Vietnam.

BACKGROUND AND AIMS: Vietnam implemented numerous measures to reduce the transmission of COVID-19 among school students, including study-at-home/self-quarantine. During the study-at-home period, adolescents may engage in more video gaming than usual, potentially contributing to gaming disorder. However, the regionally-representative prevalence of gaming disorder and its association with parenting practice and discipline practice have not been described. We assessed the prevalence of gaming disorder among Vietnamese adolescents during the initial 6 months of the COVID-19 pandemic and the associations between gaming disorder and parenting practice and discipline practice. METHODS: We conducted a school-based, self-administered cross-sectional survey of 2,084 students in Hanoi, Vietnam (response rate = 97.1%). The survey included standardized instruments translated from English to Vietnamese. We performed multilevel logistic regressions to assess the associations between parenting practice, discipline practice, and gaming disorder. RESULTS: The prevalence of gaming disorder among the respondents was 11.6%. Healthy parent-child relationship was protective against gaming disorder (Adj OR = 0.36; 95% CI = 0.21, 0.62). Non-supervision, non-discipline, violent discipline were positively associated with gaming disorder. DISCUSSION AND CONCLUSIONS: We found associations between gaming disorder and parent-child relationship, parental supervision, and parental discipline. Future interventional studies should consider assessing the effect of fostering healthy parent-child relationships and appropriate discipline on the occurrence or prognosis of gaming disorders.

Harms to children from the financial effects of others' drinking.

BACKGROUND: Many children live with parents who drink and experience little impact, but risky or heavy drinking by caregivers can result in a range of harms to children. Alcohol-related financial harms which directly impact children's needs in general populations have been seldom studied. OBJECTIVE: The study aims to identify the prevalence and correlates of financial harms from others' drinking affecting children's needs in nine lower- and middle-income (LMICs) and high-income countries (HICs). METHODS: Participants (n = 7,669) from Brazil, Chile, Ireland, Lao PDR, Nigeria, Sri Lanka, Thailand, USA and Viet Nam were aged 18-64 years and living with children. Logistic regression and meta-analyses explored differences in financial harm affecting children among LMICs and HICs, adjusting for gender, education, rurality and drinking pattern. RESULTS: In around one-tenth to a third of households in the nine countries, children lived with people who drank riskily. Less than 1% to 8% of respondents reported that their children's needs had not been met because of financial harm from others' drinking. Women reported significantly greater harm to children due to the financial effects of others' drinking than men in the USA, Nigeria and Viet Nam. When the participant reported drinking riskily, and particularly when families included someone who drank heavily, increased odds of financial harm from others' drinking affecting children were identified. CONCLUSION: That children's needs were not met due to financial harm from others' drinking was reported by three percent (<1 to 8%) of caregivers across the nine countries, representing a problem for large numbers of children, particularly in the low and middle-income countries studied. When a person's drinking was reported to be heavy or harmful within the family, the risk that children's needs were affected by the financial impacts of others' drinking was significantly greater.

Socioeconomic inequalities in alcohol use and some related consequences from a household perspective in Vietnam.

INTRODUCTION AND AIMS: Alcohol-related harm reduction may target individuals, their households or communities. This study investigates the prevalence of and socioeconomic inequalities in alcohol use and alcohol-related consequences (injury, accident, property loss and interpersonal violence) at the family-level. DESIGNS AND METHODS: A cross-sectional survey of 2394 households was conducted in eight provinces from six socioeconomic regions and two metropolitan cities in Vietnam. Family-level alcohol use and injury were computed from individual data, while other measures were on a household basis. Unstandardised and indirectly standardised concentration index was used to measure degree of expenditure-based inequality in alcohol use and its consequences. RESULTS: Over the previous 12 months, 88.5% and 46.2% of households had at least one current-drinker and one heavy episodic drinking person, and in 41.7% the heavy episodic drinking person was the breadwinner. About 5.3% of households suffered alcohol-related injury, accident or property loss; 11.4% reported alcohol-related interpersonal violence. Poor and near-poor households suffered the double-burdens of both having heavy episodic drinking person and alcohol-related harm. A modest socioeconomic gradient was observed with all types of drinker, more concentrated among higher living-standard households, especially in urban areas. However, there was a persistent high-level inequality disadvantaging lower living-standard families, especially in rural areas, in suffering all measured alcohol-related harms. DISCUSSION AND CONCLUSIONS: Alcohol use and alcohol-related consequences are highly prevalent in Vietnam. Lower socioeconomic households, especially in rural areas, are important target groups for alcohol-related harm prevention and reduction interventions. The concentration index appeared to be a useful measure of inequalities in alcohol-related harms.

Harm from Known Others' Drinking by Relationship Proximity to the Harmful Drinker and Gender: A Meta-Analysis Across 10 Countries.

BACKGROUND: Drinking is a common activity with friends or at home but is associated with harms within both close and extended relationships. This study investigates associations between having a close proximity relationship with a harmful drinker and likelihood of experiencing harms from known others' drinking for men and women in 10 countries. METHODS: Data about alcohol's harms to others from national/regional surveys from 10 countries were used. Gender-stratified random-effects meta-analysis compared the likelihood of experiencing each, and at least 1, of 7 types of alcohol-related harm in the last 12 months, between those who identified someone in close proximity to them (a partner, family member, or household member) and those who identified someone from an extended relationship as the most harmful drinker (MHD) in their life in the last 12 months. RESULTS: Women were most likely to report a close male MHD, while men were most likely to report an extended male MHD. Relatedly, women with a close MHD were more likely than women with an extended MHD to report each type of harm, and 1 or more harms, from others' drinking. For men, having a close MHD was associated with increased odds of reporting some but not all types of harm from others' drinking and was not associated with increased odds of experiencing 1 or more harms. CONCLUSIONS: The experience of harm attributable to the drinking of others differs by gender. For preventing harm to women, the primary focus should be on heavy or harmful drinkers in close proximity relationships; for preventing harm to men, a broader approach is needed. This and further work investigating the dynamics among gender, victim-perpetrator relationships, alcohol, and harm to others will help to develop interventions to reduce alcohol-related harm to others which are specific to the contexts within which harms occur.

Arsenic geochemistry of groundwater in Southeast Asia.

The occurrence of high concentrations of arsenic in the groundwater of the Southeast Asia region has received much attention in the past decade. This study presents an overview of the arsenic contamination problems in Vietnam, Cambodia, Lao People's Democratic Republic and Thailand. Most groundwater used as a source of drinking water in rural areas has been found to be contaminated with arsenic exceeding the WHO drinking water guideline of 10 µg·L(-1). With the exception of Thailand, groundwater was found to be contaminated with naturally occurring arsenic in the region. Interestingly, high arsenic concentrations (> 10 µg·L(-1)) were generally found in the floodplain areas located along the Mekong River. The source of elevated arsenic concentrations in groundwater is thought to be the release of arsenic from river sediments under highly reducing conditions. In Thailand, arsenic has never been found naturally in groundwater, but originates from tin mining activities. More than 10 million residents in Southeast Asia are estimated to be at risk from consuming arsenic-contaminated groundwater. In Southeast Asia, groundwater has been found to be a significant source of daily inorganic arsenic intake in humans. A positive correlation between groundwater arsenic concentration and arsenic concentration in human hair has been observed in Cambodia and Vietnam. A substantial knowledge gap exists between the epidemiology of arsenicosis and its impact on human health. More collaborative studies particularly on the scope of public health and its epidemiology are needed to conduct to fulfill the knowledge gaps of As as well as to enhance the operational responses to As issue in Southeast Asian countries.

Arsenic geochemistry and human health in South East Asia.

Arsenic occurs naturally in many environmental components and enters the human body through several exposure pathways. Natural enrichment of arsenic may result in considerable contamination of soil, water, and air. Arsenic in groundwater can exceed values hundreds of time higher than the concentration recommended for drinking water. Such exposure levels indicate a serious potential health risk to individuals consuming raw groundwater. Human activities that have an impact on the environment may increase the distribution of inorganic arsenic. Abandoned mines are of great concern due to the extremely high arsenic concentrations detected in mine drainage and tailings. Diet, drinking water, air, soil, and occupational exposures are all sources of inorganic arsenic for humans. Interdisciplinary efforts to better characterize the transport of arsenic and reactants that facilitate their release to the environment are important for human health studies. Multi-disciplinary efforts are needed to study diet, infectious disease, genetics, and cultural practices unique to each region to better understand human health risk and to design public health interventions.

Community exposure to arsenic in the Mekong river delta, Southern Vietnam.

We examined the daily inorganic arsenic (i-As) intake from drinking water and rice in 45 households (75 individuals) in the An Giang province, Southern Vietnam. The daily i-As intake ranged from 28-102 µg d(-1), equivalent to the daily dose of 0.6-1.9 µg d(-1) kg((body wt))(-1). Increased As concentrations were observed in human hair in the study location. Approximately 67% (n = 44), 42% (n = 28), and 15% (n = 10) of the hair samples had As levels exceeding 1, 3, and 10 µg g(-1), respectively. The total As concentrations in female and male hair correlated well with the total daily i-As intake. Measurement of As concentrations in the hair of people who were consuming or had previously consumed As from contaminated sources may help predict the onset of negative health effects. We suggested an application of the Bayes's theorem to calculate the probability that an individual in a population will acquire a negative health effect, given that the concentration of arsenic in the subject's hair has been determined.
