[Epidemiological study on alcohol consumption and agricultural profession-related injuries among minority residents from the northern parts of China].

OBJECTIVE: To understand the incidence rates of agricultural profession-related injuries and the relationship to alcohol consumption. METHODS: A multistage sample of 2366 villagers was selected from Minority Nationality Villages, Heilongjiang province. Face-to-face interviews were conducted by trained interviewers during May 2008. 2198 (92.9%) of the eligible questionnaires were available. RESULTS: Incidence rate of agricultural profession-related injury rate was 11.8% (260/2198) from May 2007 to April 2008. Higher proportions of injuries were seen for males, 30 - 49 year olds, farmers and among those people working on farms for 10 years or more, smoking during farm work, with sleeping disorder, using motor vehicles, and those using agricultural machinery. Rate of alcohol drinking was 29.1% (640/2198) in the month prior to the investigation. Results from logistic regression models showed that alcohol consumption patterns and other alcohol-related behavior were examined in separate logistic models because of collinearity by controlling the variables that were associated with agricultural profession-related injury including sex, age, years of farm work, driving a motor vehicle, and agricultural machinery use etc. In each model, the reference group was those villagers who did not drink in the past month. The odds of injury among villagers with history of past month drinking, who drank distilled spirits, and alcohol drinking at breakfast and lunch were 1.80 (95%CI: 1.24 - 2.62), 2.09 (95%CI: 1.38 - 3.15), 2.15(95%CI: 1.43 - 3.22) respectively. The odds of agricultural injury also significantly increased with greater average amounts of pure alcohol per day, with increased frequency of drinking per week, and reported years of drinking. CONCLUSION: Intervention efforts should include increasing awareness about alcohol drinking as a major risk factor causing agricultural injuries as well as controlling alcohol drinking, improving knowledge about driving motor vehicle and using agricultural machinery.

[Protective effect of lycopene on the oxidative damage of lung in rat induced by ozone].

OBJECTIVE: To observe the effect of Lycopene (LP) on the oxidative damage of lung induced by exposing ozone. METHODS: The injury model of lung was induced by exposing ozone. The xanthines oxidize method and TBA was used to determine SOD, MDA and GSH-Px in serum and lung respectively. RESULTS: Compared with model rats, SOD and GSH-Px in the group of LP administrated were increased and MDA were decreased significantly (P < 0.05). CONCLUSION: it was showed that LP could protect oxidative damage of lung induced by ozone in rats.
