Objectives
To analyse trends in smoking prevalence in Ukraine from three surveys conducted in 2001–5, and to explore correlates of observed changes, in order to estimate the stage of tobacco epidemic in Ukraine.Design
Repeated national interview surveys in Ukraine in 2001, 2002 and 2005.Main outcome measure
Prevalence of current smoking among the population aged ⩾15 years.Results
The age‐standardised prevalence of current smoking in Ukrainian men was 54.8% in 2001 and 66.8% in 2005. Among Ukrainian women, prevalence increased from 11.5% in 2001 to 20.0% in 2005. ORs for yearly increase in prevalence were estimated as 1.164 (95% CI 1.111 to 1.220) for men and 1.187 (1.124 to 1.253) for women, which implies that, on average, 3–4% of men and 1.5–2% of women living in Ukraine join the smoking population each year.Conclusions
In Ukraine, smoking prevalence is increasing in most population groups. Among men, the medium deprivation group with secondary education has the highest smoking prevalence. Among women, while the most educated, young and those living in larger cities are the leading group for tobacco use, other groups are also increasing their tobacco use. Tobacco promotion efforts appear to have been significantly more effective in Ukraine than smoking control efforts. The decrease in real cigarette prices in Ukraine in 2001–5 could be the main factor explaining the recent growth in smoking prevalence.Ukraine is a large eastern European country with high smoking prevalence. Tobacco products are widely available at very low prices, and the transnational tobacco industry is extremely successful in promoting its products and lobbying for its interests in the legislative field. Advocacy of tobacco control has only recently achieved some success in the legislative field, with the first tobacco control law being adopted in late 2005. Ukraine ratified the Framework Convention on Tobacco Control in 2006, but there is still much cause for concern regarding the enforcement and effectiveness of the adopted legislative measures. Unfortunately, the government is not yet involved in nationwide surveillance of the tobacco problem, and the available data have mostly been gathered with funding from foreign donors. Several attempts have been made to measure the extent of the tobacco epidemic in the countries of the former Soviet Union (FSU).1,2,3,4,5,6,7 Most of these studies have shown rather high smoking prevalence among men (50–70%) and comparatively low prevalence among women (5–20%). Most countries in the FSU have similar smoking rates, while certain trends are shown to be related to the differences in how the transnational tobacco industry succeeds in every national tobacco market.6 Unfortunately, few studies have been published showing trends in smoking prevalence in the FSU.7 In Ukraine, two studies3,4 provided point estimates of smoking prevalence.The aim of this study was to analyse trends in smoking prevalence in Ukraine, on the basis of three surveys conducted in 2001–5, and to explore correlates of observed changes in order to estimate the stage of the tobacco epidemic in Ukraine. 相似文献5.
了解河南省部分食品中重金属污染的现状。方法 在河南省18个省辖市采集8大类3 657份食品样品,按照国家标准检测食品中铅、镉和汞的含量,检测结果按照GB 2762—2012《食品安全国家标准食品中污染物限量》进行评价。结果 河南省部分食品中铅含量的平均值为0.34 mg/kg,总体超标率为8.8%(320/3 656),其中粮食、肉类和蔬菜中超标率较高,分别为17.2%(95/552)、14.5%(85/587)和10.7%(57/534);部分食品中镉含量的平均值为0.054 mg/kg,总体超标率为3.9%(143/3 657),其中食用菌和蛋类中超标率较高,分别为9.6%(49/508)和8.1%(42/518);部分食品中汞含量的平均值为0.077 mg/kg,总体超标率为8.3%(303/3 657),其中蔬菜和粮食中超标率较高,分别为25.3%(135/534)和12.3%(68/551)。结论 河南省部分食品中铅、汞污染情况较为严重,其中粮食、蔬菜和肉类食品中污染情况尤为突出,需要加强监管。 相似文献

Study of selenium accumulation by fish of Buryatia shows relatively high accumulation level for the Baikal lake (213-513 mcg/kg) contrary to the lakes of Baunt and Selenginsk regions of the republic (84-227 mcg/kg). Selenium deficiency in Baunt region is also confirmed by low selenium levels in meat of native origin (39-95 mcg/kg). Among different tissues and organs the lowest selenium levels are typical for muscles, the value increasing in the row: muscle < skin < air bladder < scales < fin < liver < roe. 相似文献

转录组测序技术能将组织或细胞在不同生理条件下的差异基因量化,是探索基因功能和揭示特定生物学过程中分子机理的必要手段。储粮害虫是严重危害储藏粮食的一类害虫,从转录组水平揭示储粮害虫生长发育、关键基因功能、抗药性分子机制等成为研究热点,极大促进了对储粮害虫特别是无参考基因组信息的害虫的研究。因此,本文系统性从生长发育相关基因的挖掘、组织特异性基因、与微生物互作机制、对环境胁迫的响应机制、磷化氢抗性机理和植物精油杀虫机理研究六个方面综述了转录组学在储粮害虫研究中的应用,旨在为储粮害虫的深入研究提供参考,对进一步进行储粮害虫防治技术开发提供理论依据。 相似文献

Aflatoxins in spices marketed in Portugal 总被引:3,自引:0,他引:3
Maria Ligia Martins Herminia Marina Martins Fernando Bernardo 《Food Additives & Contaminants》2001,18(4):315-319
Seventy-nine prepackaged samples of 12 different types of spice powders (five cardamom, five cayenne pepper, eight chilli, five cloves, seven cumin, five curry powder, five ginger, five mustard, 10 nutmeg, 12 paprika, five saffron and seven white pepper) were selected from supermarkets and ethnic shops in Lisbon (Portugal) for estimation of aflatoxins by immmunoaffinity column clean-up followed by HPLC. Aflatoxin B (AFB) was detected in 34 samples of prepackaged spices (43.0%). All of the cayenne pepper samples were contaminated with levels ranging from 2 to 32 µ g AFB / kg. Three nutmeg samples contained levels ranging from 1 to 5 µ g/kg, three samples had levels ranging from 6 to 20 µ g/kg, and there were two with 54 µ g/kg and 58 µ g/ kg. Paprika contained levels of aflatoxin B1 ranging from 1 to 20 µ g/kg. Chilli, cumin, curry powder, saffron and white pepper samples had levels ranging from 1 to 5 µ g/kg. Aflatoxins were not detected in cardamom, cloves, ginger and mustard. None of the samples analysed contained aflatoxins B2, G1 and G2. 相似文献
