For the determination of the heavy metals concentration, the samples were ashed and washed with hydrochloric acid according to standard method. The bioaccessibility test employed the Stimulated Epithelial Lung Fluid (SELF). The total concentration of heavy metals in the four samples investigated ranged between 9.7 - 14.9 μg/g, 24.1 - 37.0 μg/g, 41 - 69 μg/g and 153 - 183 μg/g for cadmium, chromium, nickel and zinc respectively. The percentage inhalation bioaccessibility fraction of the four samples investigated ranged between 20.8% - 59.8%, 3.3% - 8.1%, 21.7% - 48.8% and 7.6% - 12.5% for cadmium, chromium, nickel, and zinc respectively. Statistical analyses using SPSS 21, revealed significant differences in the total concentration of heavy metals in the samples investigated except for Zinc. Risk assessment based on daily consumption of 10 g of the tobacco snuff employing total concentration of the heavy metals suggests that excluding nickel, all other metals investigated indicated daily intake values above WHO permissible levels. However, with the bioaccessible fractions, only cadmium, a known carcinogen indicated levels above WHO limits. From the results of this study, it can be deduced that consumption of tobacco snuff may induce negative health effects such as cancer and its attendant complications, the risk analysis based on bioaccessible concentration suggests lower health risk than analysis based on total heavy metal concentration;hence the assumption that snuff is a safe alternative to tobacco smoking may be erroneous.展开更多

The combination of low socioeconomic status and substance use can be described as a social and economic disaster for many poor families of Africa. While majority of studies concentrated on cigarette smoking, few studies in Nigeria has been conducted on non-smoke forms of tobacco. The burden of marijuana abuse is also rising in the Nigeria. Similar to cigarette smoking, cannabis use is more common among males. Knowledge of the pattern of tobacco and cannabis use in the community is important considering the public health implications. The aim of this study was to determine the prevalence of tobacco (cigarette smoking and snuff) and cannabis use among adults in an urban communities Enugu, southeast Nigeria. Methods: This was a cross-sectional descriptive study conducted in urban slum settlements in Enugu, the capital of Enugu State, southeast Nigeria. Using a semi structured questionnaire, we collected data selected socio-demographic characteristics, including tobacco use and cannabis use in the last 30 days. The study was conducted between August and December 2013. For database management and statistical analyses, we used the SPSS version 23. Results: The total number of individuals recruited in the study was 1572;844 (52.8%) females and 728 (45.5%) males with a male to female ratio of 0.9:1. Tobacco was used by a total of 270 (17.2%) individuals within the last 4 weeks and marijuana by 23 (1.5%) of the population. Overall, 280 (17.8%) used either one or both tobacco and marijuana. While snuff was predominately used from 60 years and above, cigarette smoking peaked at 30 - 39 years and marijuana use peaked at a younger age of 20 - 29 years. Cigarette smoking positively correlated with male gender (male 1, female 0) and alcohol use (Yes 1, No 0). P Conclusion: The prevalence of cigarette smoking (5.5%), snuff (11.6%) and marijuana use (1.6%) was found in an urban settlement in Enugu. Predictors of tobacco use were older age, male gender and alcohol use. Public health intervention programs should reemphasize the health-related issues associated with these substances and the need to quit using them.展开更多

Differences in educational levels in cardiovascular risks have not been completely defined. This study was set out to evaluate the influence of levels of education on the risks of cardiovascular disease in an urban community in Awka, southeast Nigeria. <strong>Methodology:</strong> In this cross sectional study of 294 subjects conducted in Awka in 2017, biodata, anthropometric and demographic data were obtained. A questionnaire was used to extract information on smoking, alcohol use, tobacco snuff use, diabetes mellitus status, time spent at work > 10 hours daily and night sleep duration < 4 hours. Blood pressure and body mass index were measured. Data were analyzed and the association between levels of education and the potential cardiovascular risks determined. <strong>Results: </strong>The prevalence of smoking was 5.4%, tobacco snuff use 5.4%, alcohol 42.2%, thickened arterial wall 27.2%, meat protein 91.8%, diabetes mellitus 9.5%, time spent at work > 10 hours daily 29.3%, obesity 33.3%, hypertension 58.5%, night sleep < 4 hours 5.4%. Levels of education has association with tobacco use (p = 0.009), alcohol use (p = 0.013), thickened arterial wall (p < 0.001), diabetes mellitus (p < 0.001), time spent at work > 10 hours daily (p < 0.001), obesity (p = 0.020), hypertension (p < 0.001), meat consumption (p = 0.047). However, smoking and night sleep < 4 hours have no significant association with levels of education, p = 0.415, and p = 0.132. <strong>Conclusion:</strong> There was variability in the prevalence of cardiovascular risks at different levels of education. The prevalence of smoking and night sleep duration < 4 hours did not vary with levels of education. The prevalence of tobacco snuff and thickened arterial wall was high in primary education holders and meat consumption in secondary education. Alcohol prevalence increased with increasing levels of education. Diabetes mellitus, time spent oat work > 10 hours daily, hypertension and obesity increased in prevalence with increasing levels of education but declined with tertiary education.展开更多
