The present study examined the relationship between stomach cancer and the low intake of fresh fruit and vegetables and/or a high intake of pickled, preserved or salted foods and frequent use of cooking oil. During 139,390 person-year of follow-up of over 13,000 subjects, 116 died from stomach cancer. Using a Cox proportional hazards-regression analysis of(More)
An excess of stomach cancer among workers has been observed and it could be argued that men whose occupation involves heavy work eat more and are consequently exposed to a greater quantity of carcinogens in their food. Working under conditions of heat stress greatly increases a worker's salt excretion by as much as 0.1-15.0 g through sweating during one(More)
In response to the request for 'Breakthrough Questions' for 'Grand Challenges in Global Health' recently published in Nature, the Asian Pacific Organization for Cancer Prevention should focus its attention on what projects are of the highest priority for integration with its Practical Prevention Program (PPP). The most common female cancers in most of the(More)
BACKGROUND Health information in general and cancer information in particular in Viet Nam is an basic data for decisions related to health planning prevent against cancer. However, very limited database of cancer information bas been available to date. The aim of the present study was to examine cancer mortality pattern nationwide in Viet Nam. METHODS(More)
Background: As there is a lack of data on stomach cancer disease in Asia, the aim of the present study was to examine patterns and time trends for this neoplasm in Asian countries. Methods: A descriptive study was designed to examine the cancer pattern and time trend and to calculate the annual change in mortality and incidence of stomach cancer at 5-year(More)
Viet Nam had the highest reported male smoking prevalence rate (72.8-74.3%) in the world in the 1990s. Production of tobacco products was about 0.44 kg or 600 cigarettes per capita per year in 1994 for domestic use. Population-attributable risk per cent of lung cancer due to smoking was about 69.7%. Males in the south have a lower reported smoking(More)
BACKGROUND Several studies have established a relationship between temperature and mortality. In particular, older populations have been shown to be vulnerable to temperature effects. However, little information exists on the temperature-mortality relationship in Vietnam. OBJECTIVES This article aims to examine the monthly temperature-mortality(More)
OBJECTIVES This study evaluated the levels of exposure to polycyclic aromatic hydrocarbons (PAHs) and their relationship with oxidative DNA damage among Vietnamese coke-oven workers. METHODS We collected urine from 36 coke-oven workers (exposed group) at the beginning and end of the shift on 2 consecutive days. We also collected urine from 78 medical(More)
BACKGROUND Food change due to cooking temperature and unrecognized heat-formed chemical carcinogens may impact on the risk of stomach and colo-rectal cancers. To test this hypothesis a case-control study was performed. METHODS A total of 670 cases of stomach and colo-rectal cancers matched with 672 hospital controls for sex and -/+5 years age admitted to(More)
BACKGROUND The International Collaborative Epidemiological Study of Host and Environmental Factors for Stomach and Colorectal Cancers in Southeast Asian Countries (SEACs) has been conducted in Viet Nam from 2003 to 2008 on a case-control basis. For further effective primary prevention, we examined gastric and colorectal cancer mortality nationwide in eight(More)
