Significant changes in preference of illicit drug use in a population of Hanoi, Vietnam-A 6-year wastewater study (2018-2023).

Background And Aim: Illicit drug use causes great harm and economical loss to society, yet there is limited understanding of its prevalence in the population in low-income countries like Vietnam where survey resources are scarce. In this study, we used wastewater analysis as a cost-effective monitoring tool to measure illicit drug use in a population of Hanoi, Vietnam, a low-income country in Southeast Asia.

Design, Setting And Participants: This is a longitudinal observational study.

Six years of alcohol consumption in Hanoi, Vietnam, by wastewater analysis: Assessing changes impacted by socio-economical factors.

Objectives: Alcohol consumption in Vietnam increased significantly over past decade alongside its economic development. However, in recent years, several alcohol control measures including a new drink-driving law and taxes as well as the COVID-19 pandemic have affected the consumption levels. This study aimed to monitor alcohol use trends in Hanoi over six consecutive years.

Assessing the impact of individual exposure to air pollution via biomarkers in sputum of children in Ho Chi Minh city, Vietnam.

Understanding the impact of exposure to air pollution on children's health is critical for developing effective child health protection policies. Alveolar macrophage black carbon (AMBC) provides an indicator of personal exposure to air pollution. Hence, we aimed to examine air pollution exposure and its effects on children by measuring AMBC area and inflammatory cytokines in sputum.

The impact of diurnal temperature range on the risk of hospitalizations in a low-income setting: the case of the Central Coast of Vietnam.

The study aims to evaluate the effects of diurnal temperature range (DTR) on all causes, cardiovascular and respiratory conditions in the Central Coast of Vietnam, a tropical, low-income region with high DTR exposure but limited research. Daily hospital admission data from the largest hospitals in three provinces were analyzed alongside meteorological data. A time-series analysis using a generalized linear distributed lag model was conducted to examine the non-linear DTR-hospitalization association.

Assessing the impact of stricter drink driving policy on alcohol consumption in a population of Hanoi, Vietnam using wastewater analysis.

Introduction: On 1 January 2020, Vietnam introduced a new law with harsher fines and penalties for driving under the influence of alcohol. Reports of empty beer restaurants following this implementation suggested the new law has the potential to reduce population-level alcohol consumption. This pilot study aims to quantify short-term changes in alcohol consumption levels after the implementation of the new law and assess whether it could lead to a reduction in total alcohol consumption in the population.

Indoor air pollution is associated with respiratory symptoms in children in urban Vietnam.

Exposure to indoor air pollution (IAP) is a leading environmental risk for respiratory diseases. We investigated the relationship between respiratory symptoms and polluting indoor activities such as smoking, cooking and contact with pets among children in Ho Chi Minh City (HCMC), Vietnam. A cross-sectional survey applied a multistage sampling method in 24 randomly selected secondary schools across the city.

Impact of temperature on hospital admission for acute lower respiratory infection (ALRI) among pre-school children in Ho Chi Minh City, Vietnam.

Changes in ambient temperature have been reported as an important risk factor for respiratory diseases among pre-school children. However, there have been few studies so far on the effects of temperature on children respiratory health in developing countries including Vietnam. This study examined the impact of short-term changes in ambient temperature on hospital admissions for acute lower respiratory infection (ALRI) among children aged less than 5 years old in Ho Chi Minh City (HCMC), Vietnam.
