DESIGN, SETTING, PARTICIPANTS AND MEASUREMENTS: A cross-sectional analysis of adult (≥ 18 years) current smokers and ex-smokers from 14 countries participating in the ITC Project. Data from the most recent survey questionnaire for each country were included, which spanned the period 2013-17. Countries were categorized into four groups based on regulations governing NVP sales and marketing (allowable or not), and level of enforcement (strict or weak where NVPs are not permitted to be sold): (1) most restrictive policies (MRPs), not legal to be sold or marketed with strict enforcement: Australia, Brazil, Uruguay; (2) restrictive policies (RPs), not approved for sale or marketing with weak enforcement: Canada, Malaysia, Mexico, New Zealand; (3) less restrictive policies (LRPs), legal to be sold and marketed with regulations: England, the Netherlands, Republic of Korea, United States; and (4) no regulatory policies (NRPs), Bangladesh, China, Zambia. Countries were also grouped by World Bank Income Classifications. Country-specific weighted logistic regression models estimated adjusted NVP prevalence estimates for: awareness, ever/current use, and frequency of use (daily versus non-daily).
FINDINGS: NVP awareness and use were lowest in NRP countries. Generally, ever- and current use of NVPs were lower in MRP countries (ever-use = 7.1-48.9%; current use = 0.3-3.5%) relative to LRP countries (ever-use = 38.9-66.6%; current use = 5.5-17.2%) and RP countries (ever-use = 10.0-62.4%; current use = 1.4-15.5%). NVP use was highest among high-income countries, followed by upper-middle-income countries, and then by lower-middle-income countries.
CONCLUSIONS: With a few exceptions, awareness and use of nicotine vaping products varied by the strength of national regulations governing nicotine vaping product sales/marketing, and by country income. In countries with no regulatory policies, use rates were very low, suggesting that there was little availability, marketing and/or interest in nicotine vaping products in these countries where smoking populations are predominantly poorer. The higher awareness and use of nicotine vaping products in high income countries with moderately (e.g. Canada, New Zealand) and less (e.g. England, United States) restrictive policies, is likely due to the greater availability and affordability of nicotine vaping products.
Objectives: The aim of this study was to assess the relationship between khat and occlusal caries progression.
Methods: A cohort study was carried out among 98 Yemeni khat chewers and 101 non-chewers aged 18-35 years old with early occlusal caries lesions. All participants answered questions on socio-demographic, khat , oral hygiene , sugar intake, and oral health knowledge at baseline. All posterior teeth with an early enamel lesion on occlusal surfaces detected by visual inspection at baseline were also subjected to DIAGNOdent assessment to confirm early lesion (DIAGNOdent reading 13-24). Participants were re-examined after 12 weeks. Caries progression was considered to occur when the DIAGNOdent reading was >25. Data were analyzed using Relative risk, Mann-Whitney U test, a Wilcoxon Signed-Rank test and logistic regression analysis.
Results: Occlusal caries progression incidence between khat chewers and non-chewers, with the relative risk was 1.68. There was no significant difference in occlusal caries progression on chewing side and non-chewing side among khat chewers. Khat chewing was a statistical predictor for those with low income.
Conclusion: Khat is a risk factor for occlusion caries progression among low income group.
METHOD: A cross-sectional study was carried out among public secondary school teachers, aged 18 - 60 years, in Enugu East Senatorial District, using probability proportional to size sampling and systematic random sampling to select 1000 participants. Binary and multiple logistic regression analyses were used to determine association. An odds ratio with a 95% confidence interval (CI) was computed to determine the level of significance.
RESULTS: The current practice level of family planning is 26.5%. Respondents with bachelor in education were 2 times more likely to be a current user of family planning (AOR=2.39; 95% CI: 1.25-4.55). However, respondents in age group 38 years and above were less likely to be a current user of family planning (AOR=0.64; 95% CI: 0.43-0.95), likewise female respondents (AOR=0.66; 95% CI: 0.44-0.98). Additionally, respondents who mentioned radio (AOR=0.64; 95%CI: 0.44-0.93), social media (AOR=0.73; 95% CI: 0.53-0.99) and healthcare (AOR=0.61; 95%CI: 0.43-0.88) as source of information were less likely to be current user of family planning. Whereas, partner who encouraged the use of family planning (AOR=2.54; 95% CI: 1.71-3.78) span style="font-family:'Times New Roman'; font-weight:bold">, partner who allow each other to decide on family planning methods (AOR=4.47; 95% CI: 2.67-7.48) and those who had good knowledge of family planning (AOR=1.96; 95% CI: 1.40-2.67) were more likely to be current user of family planning.
CONCLUSION: The level of current practice of family planning is low and a significant number of factors predict the current practice of family planning. A family planning educational workshop among teachers is needed to improve teacher's knowledge on family planning to address the issue of adolescent sexual reproduction as teachers are vessels of knowledge impartation to students.
