Alcohol Use and Alcohol Consumption–Related Problems in Rural Vietnam: An Epidemiological Survey Using AUDIT

This study aimed to assess alcohol use and alcohol consumption–related problems in different sociodemographic groups in a rural district in Vietnam. Interviews were completed between March 2004 and July 2004. The Alcohol Use Disorder Identification Test (AUDIT) was applied to interview 3423 people, who were randomly selected in a rural district (1695 men and 1728 women). People who had an AUDIT score greater than 7 (in men) or greater than 5 (in women) were identified as having alcohol consumption–related problems. Prevalences and adjusted odds ratios of alcohol use and alcohol consumption–related problems were estimated for different subgroups of the population. Weekly and daily “binge drinking” among men were 5.7 and 3.6%, while binge drinking in women was virtually nonexistent. The prevalence of alcohol consumption–related problems was 25.5% among men and 0.7% among women. The differences between sociodemographic groups were not strong, but women who were separated, divorced, or widowed as well as those with higher education had significantly higher rates of alcohol consumption–related problems than married women and those with lower education. This study indicates an urgent need for alcohol intervention programs focused on men. However, further monitoring of alcohol use and problems among women is important to follow-up changes in consumption pattern. The studys limitations are discussed.

Self-reported illness and use of health services in a rural district of Vietnam: findings from an epidemiological field laboratory

Aims: The aims of the study were to assess the pattern of self-reported illness as well as use of health services in a rural district in Vietnam, and to analyse these in relation to gender, age, educational level, occupation, and economic status. Methods: A population-based survey of 11,089 households was conducted in 1999. Through household interviews, data were collected on self-reported health, use of health services during four weeks prior to the interview, and other background factors. Results: The prevalence of self-reported illness was 48%. Cough, fever, and headache were the most commonly reported symptoms (20%) while cardiovascular disorders were least reported (0.6%). Occurrence of illness was significantly lower in groups with higher education, especially among men, but there was no difference between occupational and economic groups. Self-treatment was very common (69%). Private health facilities were used to a large extent, while community health stations played a less important role. Use of district hospitals was significantly higher among employed people. Discussion: An epidemiological field laboratory enabled analysis of self-reported illness and use of health services, which is important for planning of health services. We found a high level of reported illness but a very low utilization of community health services. Better knowledge about illness patterns could be important for improving quality of and access to community health services.

Self-reported chronic diseases and associated sociodemographic status and lifestyle risk factors among rural Vietnamese adults.

AIMS The fact that chronic diseases are leading causes of mortality and morbidity in hospitals in Vietnam was certified by yearly statistical information. However, population-based knowledge of chronic diseases is still largely lacking. This article examines the prevalence of major chronic diseases and their relationships with sociodemographic status and selected lifestyle risk factors among the adult population in a rural community in the north of Vietnam. METHODS A representative sample comprising 2500 adults aged 25-74 years was surveyed in 2005 using a structured questionnaire. Both descriptive and analytical statistical analyses were applied. RESULTS Thirty-nine per cent of the respondents had at least one of the studied chronic diseases. The prevalence of current smoking was 59% among men and 0.7% among women. The prevalence of at-risk alcohol drinking was 67% among men and 3% among women. Increasing age, low education and doing other jobs (small traders, temporary workers, housekeepers, handicraft makers and jobless), as well as tobacco use and at-risk alcohol drinking, were found to be associated with a higher probability of having at least one chronic disease of interest. Economic status was found to be inversely correlated with the probability of having at least one chronic disease among women only. CONCLUSIONS The findings from this study indicated that chronic conditions and lifestyle risk factors were very common among the adult population in rural Vietnam. There is an association between chronic diseases and lower socioeconomic status and unhealthy lifestyle risk factors.Aims: The fact that chronic diseases are leading causes of mortality and morbidity in hospitals in Vietnam was certified by yearly statistical information.

Alcohol-related harm among university students in Hanoi, Vietnam

Introduction and Aim : This study examines the prevalence of and risk factors for alcohol-related harm and types of harm among medical students from Hanoi Medical University (Vietnam). Risk factors include aspects of drinking patterns and relevant socio-demographic variables. Study Design and Methods : A cross-sectional study involving 1st to 6th year students (N=1216; response rate 96.5%). Of these, 210 students from each academic year were randomly selected from a sampling frame covering all students from each academic year. Data were collected using a questionnaire distributed in class by researchers. Drinkers completed 23 questions on alcohol-related harm categorized into: 1) ‘negative influence on daily activities’; 2) ‘social conflict’; 3) ‘loss of control, acute consequences, and withdrawal’; 4) ‘mental health conditions’; and 5) ‘physical and medical health problems’. Logistic and Poisson regression models were used to identify the predictors of alcohol-related harm and the amount of harm, respectively. Results : The prevalence of alcohol use associated with at least one or more of the five types of harm was higher in men (81.8%) than in women (60.4%). In female and male students, the most common harm category was ‘loss of control, acute consequences, and withdrawal’ (51.8 and 75.6%, respectively), followed by ‘negative influence on daily activities’ (29.4 and 55.8%, respectively). Age, living away from home, and average number of standard drinks per occasion among male drinkers, and age and frequency of drinking per week among female drinkers were associated with alcohol-related harm. Conclusions : These data suggest that alcohol-related harm represents a serious public health problem among young educated individuals in Vietnam. The risk factors indicate that prevention should be aimed at aspects of drinking patterns and specific subpopulations defined by gender, age, and (for men only) type of living situation.

The effect of temperature on cardiovascular disease hospital admissions among elderly people in Thai Nguyen Province, Vietnam

Background Projected increases in weather variability due to climate change will have severe consequences on human health, increasing mortality, and disease rates. Among these, cardiovascular diseases (CVD), highly prevalent among the elderly, have been shown to be sensitive to extreme temperatures and heat waves. Objectives This study aimed to find out the relationship between daily temperature (and other weather parameters) and daily CVD hospital admissions among the elderly population in Thai Nguyen province, a northern province of Vietnam. Methods Retrospective data of CVD cases were obtained from a data base of four hospitals in Thai Nguyen province for a period of 5 years from 2008 to 2012. CVD hospital admissions were aggregated by day and merged with daily weather data from this period. Distributed lag non-linear model (DLNM) was used to derive specific estimates of the effect of weather parameters on CVD hospital admissions of up to 30 days, adjusted for time trends using b-splines, day of the week, and public holidays. Results This study shows that the average point of minimum CVD admissions was at 26°C. Above and below this threshold, the cumulative CVD admission risk over 30 lag days tended to increase with both lower and higher temperatures. The cold effect was found to occur 4-15 days following exposure, peaking at a weeks delay. The cumulative effect of cold exposure on CVD admissions was statistically significant with a relative risk of 1.12 (95% confidence interval: 1.01-1.25) for 1°C decrease below the threshold. The cumulative effect of hot temperature on CVD admissions was found to be non-significant and was estimated to be at a relative risk of 1.17 (95% confidence interval: 0.90-1.52) for 1°C increase in the temperature. No significant association was found between CVD admissions and the other weather variables. Conclusion Exposure to cold temperature is associated with increasing CVD admission risk among the elderly population.Background Projected increases in weather variability due to climate change will have severe consequences on human health, increasing mortality, and disease rates.

Knowledge of the health consequences of tobacco smoking: a cross-sectional survey of Vietnamese adults.

BACKGROUND Although substantial efforts have been made to curtail smoking in Vietnam, the 2010 Global Adult Tobacco Survey (GATS) revealed that the proportion of male adults currently smoking remains high at 47.4%. OBJECTIVES To determine the level of, and characteristics associated with, knowledge of the health consequences of smoking among Vietnamese adults. DESIGN GATS 2010 was designed to survey a nationally representative sample of Vietnamese men and women aged 15 and older drawn from 11,142 households using a two-stage sampling design. Descriptive statistics were calculated and multivariate logistic regression was used to examine associations between postulated exposure factors (age, education, access to information, ethnic group etc.) and knowledge on health risks. RESULTS General knowledge on the health risks of active smoking (AS) and exposure to second hand smoke (SHS) was good (90% and 83%, respectively). However, knowledge on specific diseases related to tobacco smoking (stroke, heart attack, and lung cancer) appeared to be lower (51.5%). Non-smokers had a significantly higher likelihood of demonstrating better knowledge on health risks related to AS (OR 1.6) and SHS (OR 1.7) than smokers. Adults with secondary education, college education or above also had significantly higher levels knowledge of AS/SHS health risks than those with primary education (AS: ORs 1.6, 1.7, and 1.9, respectively, and SHS: ORs 2.4, 3.9, and 5.7 respectively). Increasing age was positively associated with knowledge of the health consequences of SHS, and access to information was significantly associated with knowledge of AS/SHS health risks (ORs 2.3 and 1.9 respectively). Otherwise, non-Kinh ethnic groups had significantly less knowledge on health risks of AS/SHS than Kinh ethnic groups. CONCLUSIONS It may be necessary to target tobacco prevention programs to specific subgroups including current smokers, adults with low education, non-Kinh ethnics in order to increase their knowledge on health risks of smoking. Comprehensive messages and/or images about specific diseases related to AS/SHS should be conveyed using of different channels and modes specific to local cultures to increase knowledge on smoking health consequences for general population.Background : Although substantial efforts have been made to curtail smoking in Vietnam, the 2010 Global Adult Tobacco Survey (GATS) revealed that the proportion of male adults currently smoking remains high at 47.4%.

Alcohol consumption and household expenditure on alcohol in a rural district in Vietnam.

INTRODUCTION Alcohol use and alcohol-related problems are on the rise in low- and middle-income countries. Expenditure on alcohol is an important problem for families and communities and needs to be assessed. AIM This study examines level of alcohol consumption and expenditure on alcohol in a district in Vietnam. METHODS A cross-sectional survey was conducted in a rural district in northern Vietnam. Multi-stage sampling was employed to randomly select participants from 20 communities and a town in the same district. One thousand five hundred and sixty-four adults (765 males and 799 females) aged 18-60 years were interviewed. Information about alcohol use as well as expenditure on alcohol consumption four weeks prior to the interview was gathered. Non-parametric tests and log-linear regression were employed to compare expenditure on alcohol consumption across socioeconomic groups. RESULTS The prevalence of alcohol use one month prior to interview was 35% (66% among men and 5% among women). The median alcohol consumption among those who reported use of alcohol in the week prior to the interview was 7.9 standard drinks. Excessive drinking (more than 14 standard drinks per week for men and more than seven standard drinks per week for women) occurred among 35% of those who used alcohol. Median expenditure for alcohol consumption during one month by those who drank alcohol was USD 3.5, accounting for 4.6% of household food expenditure, 2.7% of total household expenditure, and 1.8% of household income. The differences in alcohol consumption and expenditure between sexes and between socioeconomic groups are also presented. CONCLUSION Our study confirms that alcohol consumption and alcohol-related problems are common among men in Vietnam. The share of alcohol expenditure in total household expenditure is substantial, especially among poor households. This should be considered an important public health issue, which needs to be taken into account in the alcohol policy debate.Introduction : Alcohol use and alcohol-related problems are on the rise in low- and middle-income countries.

Primary healthcare system capacities for responding to storm and flood-related health problems: a case study from a rural district in central Vietnam

Background As a tropical depression in the East Sea, Vietnam is greatly affected by climate change and natural disasters. Knowledge of the current capacity of the primary healthcare system in Vietnam to respond to health issues associated with storms and floods is very important for policy making in the country. However, there has been little scientific research in this area. Objective This research was to assess primary healthcare system capacities in a rural district in central Vietnam to respond to such health issues. Design This was a cross-sectional descriptive study using quantitative and qualitative approaches. Quantitative methods used self-administered questionnaires. Qualitative methods (in-depth interviews and focus groups discussions) were used to broaden understanding of the quantitative material and to get additional information on actions taken. Results 1) Service delivery: Medical emergency services, especially surgical operations and referral systems, were not always available during the storm and flood seasons. 2) Governance: District emergency plans focus largely on disaster response rather than prevention. The plans did not clearly define the role of primary healthcare and had no clear information on the coordination mechanism among different sectors and organizations. 3) Financing: The budget for prevention and control of flood and storm activities was limited and had no specific items for healthcare activities. Only a little additional funding was available, but the procedures to get this funding were usually time-consuming. 4) Human resources: Medical rescue teams were established, but there were no epidemiologists or environmental health specialists to take care of epidemiological issues. Training on prevention and control of climate change and disaster-related health issues did not meet actual needs. 5) Information and research: Data that can be used for planning and management (including population and epidemiological data) were largely lacking. The district lacked a disease early-warning system. 6) Medical products and technology: Emergency treatment protocols were not available in every studied health facility. Conclusions The primary care system capacity in rural Vietnam is inadequate for responding to storm and flood-related health problems in terms of preventive and treatment healthcare. Developing clear facility preparedness plans, which detail standard operating procedures during floods and identify specific job descriptions, would strengthen responses to future floods. Health facilities should have contingency funds available for emergency response in the event of storms and floods. Health facilities should ensure that standard protocols exist in order to improve responses in the event of floods. Introduction of a computerized health information system would accelerate information and data processing. National and local policies need to be strengthened and developed in a way that transfers into action in local rural communities.Background As a tropical depression in the East Sea, Vietnam is greatly affected by climate change and natural disasters.

Heatwaves and Hospital Admissions for Mental Disorders in Northern Vietnam

Studies in high-income countries have shown an association between heatwaves and hospital admissions for mental disorders. It is unknown whether such associations exist in subtropical nations like Vietnam. The study aim was to investigate whether hospital admissions for mental disorders may be triggered, or exacerbated, by heat exposure and heatwaves, in a low- and middle-income country, Vietnam. For this, we used data from the Hanoi Mental Hospital over five years (2008–2012) to estimate the effect of heatwaves on admissions for mental disorders. A zero-inflated negative binomial regression model accounting for seasonality, time trend, days of week, and mean humidity was used to analyse the relationship. Heatwave events were mainly studied as periods of three or seven consecutive days above the threshold of 35°C daily maximum temperature (90th percentile). The study result showed heatwaves increased the risk for admission in the whole group of mental disorders (F00-79) for more persistent heatwaves of at least 3 days when compared with non-heatwave periods. The relative risks were estimated at 1.04 (0.95–1.13), 1.15 (1.005–1.31), and 1.36 (1–1.90) for a one-, three- and seven-day heatwave, respectively. Admissions for mental disorders increased among men, residents in rural communities, and the elderly population during heatwaves. The groups of organic mental disorders, including symptomatic illnesses (F0-9) and mental retardation (F70-79), had increased admissions during heatwaves. The findings are novel in their focus on heatwave impact on mental diseases in a population habituating in a subtropical low- and middle-income country characterized by rapid epidemiological transitions and environmental changes.

Socioeconomic inequalities in catastrophic health expenditure and impoverishment associated with non-communicable diseases in urban Hanoi, Vietnam

BackgroundThe catastrophic health expenditure and impoverishment indices offer guidance for developing appropriate health policies and intervention programs to decrease financial inequity. This study assesses socioeconomic inequalities in catastrophic health expenditure and impoverishment in relation to self-reported non-communicable diseases (NCD) in urban Hanoi, Vietnam.MethodsA cross-sectional survey was conducted from February to March 2013 in Hanoi, the capital city of Vietnam. We estimated catastrophic health expenditure and impoverishment using information from 492 slum household and 528 non-slum households. We calculated concentration indexes to assess socioeconomic inequalities in catastrophic health expenditure and impoverishment. Factors associated with catastrophic health expenditure and impoverishment were modelled using logistic regression analysis.ResultsThe poor households in both slum and non-slum areas were at higher risk of experiencing catastrophic health expenditure, while only the poor households in slum areas were at higher risk of impoverishment because of healthcare spending. Households with at least one member reporting an NCD were significantly more likely to face catastrophic health expenditure (odds ratio [OR] = 2.4; 95 % confidence interval [CI], 1.8–4.0) and impoverishment (OR = 2.3; 95 % CI, 1.1–6.3) compared to households without NCDs. In addition, households in slum areas, with people age 60 years and above, and belonging to the poorest socioeconomic group were significantly associated with increased catastrophic health expenditure, while only households that lived in slum areas, and belonging to the poor or poorest socioeconomic groups were significantly associated with increased impoverishment because of healthcare spending.ConclusionFinancial interventions to prevent catastrophic health expenditure and impoverishment should target poor households, especially those with family members suffering from NCDs, with older members and those located in slum areas in Hanoi Vietnam. Potential interventions derived from this study include targeting and monitoring of health insurance enrolment, and developing a specialized NCD service package for Vietnam’s social health insurance program.
