Second-Hand Tobacco Smoke Exposure: Results of Particulate Matter (PM2.5) Measurements at Hospitality Venues in Addis Ababa, Ethiopia.

INTRODUCTION: In Ethiopia, a comprehensive smoke-free law that bans smoking in all public areas has been implemented since 2019. This study aimed to evaluate compliance with these laws by measuring the air quality and conducting covert observations at 154 hospitality venues (HVs) in Addis Ababa. METHODS: Indoor air quality was measured using Dylos air quality monitors during the peak hours of the venues, with concentrations of particulate matter <2.5 microns in diameter (PM2.5) used as a marker of second-hand tobacco smoke. A standardized checklist was used to assess compliance with smoke-free laws during the same peak hours. The average PM2.5 concentrations were classified as good, moderate, unhealthy for sensitive groups, unhealthy for all, or hazardous using the World Health Organization's (WHO) standard air quality index breakpoints. RESULTS: Only 23.6% of the venues complied with all smoke-free laws indicators. Additionally, cigarette and shisha smoking were observed at the HVs. Overall, 63.9% (95% confidence interval: 56-72%) of the HVs had PM2.5 concentrations greater than 15 µg/m3. The presence of more than one cigarette smoker in the venue, observing shisha equipment in the indoor space, and the sale of tobacco products in the indoor space were significantly associated with higher median PM2.5 concentration levels (p < 0.005). Hazardous level of PM2.5 concentrations-100 times greater than the WHO standard-were recorded at HVs where several people were smoking shisha and cigarettes. CONCLUSIONS: Most HVs had PM2.5 concentrations that exceeded the WHO average air quality standard. Stricter enforcement of smoke-free laws is necessary, particularly for bars and nightclubs/lounges.

Compliance with tobacco advertising and promotion laws at points-of-sale in Ethiopia: an observational study in 10 cities.

BACKGROUND: Ethiopia enacted a comprehensive tobacco control law in 2019, which bans tobacco advertising and promotion activities. However, compliance with these laws at points-of-sale (PoS) has not been studied, resulting in a lack of research evidence on how the regulations are implemented. The purpose of the study was to assess compliance with tobacco advertising and promotion laws at PoS in 10 cities in Ethiopia. METHODS: Multi-stage cluster sampling was used to select 1468 PoS (supermarkets, minimarkets, merchandise stores, regular shops, permanent kiosks, khat shops, street vendors, and food and drink wholesalers). Data were collected using standardized observational checklists. Tobacco advertising and promotion indicators were used to compute indoor and outdoor compliance. Poisson regression models with log link function and robust variance were used to assess factors associated with open display of cigarette packages and indoor non-compliance. RESULTS: The average indoor compliance rate was 92.9% (95% CI:92.3-93.5). Supermarkets had the highest compliance (99.7%), while permanent kiosks showed the lowest compliance (89.8%). The highest average indoor compliance was observed at PoS in Addis Ababa (98.0%). About 60% of PoS were fully compliant in indoors. Indoor open display of cigarette packages was prevalent (32.5%, 95% CI:30.0-35.1). The average outdoor compliance was 99.6% (95% CI:99.5-99.7). Outdoor full compliance was 96.5%. Open display of cigarettes was significantly higher in permanent kiosks (adjusted prevalence ratio (adjPR) 6.73; 95% CI: 3.96-11.42), regular shops (adjPR 5.16; 95% CI: 3.05-8.75), and khat shops (adjPR 2.06; 95% CI: 1.11-3.83), while indoor non-compliance was significantly higher in these same types of PoS. CONCLUSIONS: While outdoor compliance rates were relatively high, the lower indoor compliance rates particularly due to the high prevalence of open cigarette package displays indicates a major area for improvement in enforcing anti-tobacco advertising and promotion laws.

Second-Hand Tobacco Smoke Exposure and Smoke-Free Environments in Ethiopia: A Scoping Review and Narrative Synthesis.

Ethiopia passed a law prohibiting tobacco smoking in all public places in 2019. We conducted a scoping review to identify gaps in the existing literature on second-hand smoke (SHS) exposure and smoke-free environments in Ethiopia that need to be prioritised for future research to support policy and practice. We conducted systematic searches in January 2022 in the following databases: Medline, EMBASE, and PsycInfo. Two reviewers independently screened the identified study reports for eligibility and extracted data from the eligible studies. The extracted data was descriptively analysed, and research recommendations were drawn. A stakeholder consultation workshop was held to identify research topics on SHS exposure and smoke-free environments in Ethiopia that they perceived to be priorities for primary research. Of the 388 research reports identified, only nine were included in the scoping review. The topics explored includes prevalence of SHS exposure (six studies); knowledge on SHS exposure (three studies); compliance to smoke-free environments legislation (two studies); and exposure to anti-smoking messages (one study). The stakeholders prioritised further research addressing compliance monitoring and enforcement of the smoke free laws in Ethiopia. There is a need for studies that test new methods for compliance monitoring and enforcement, evaluate strategies to increase knowledge on the harms of SHS exposure and the smoke-free legislation, and evaluate the current smoke-free legislation in Ethiopia.

Malnutrition and the Survival of Cervical Cancer Patients: A Prospective Cohort Study Using the PG-SGA Tool.

BACKGROUND: Cervical cancer is the second most common cancer among women in developing countries. Malnutrition is associated with poor prognosis and early detection of malnutrition and timely nutritional interventions can improve the outcome for cervical cancer patients. The study was aimed to assess the association between the nutritional status and survival of cervical cancer patients. METHODS: A prospective cohort study design was used. Overall 175 cervical cancer patients were followed over one year period with (median 8.5 mo, range (3.6-12). RESULTS: The prevalence of malnutrition determined by means of the PG-SGA was 17.7% at admission and 47.1% at the end of follow-up. According to the SGA, one in three (29.7%) patients required nutritional intervention at the end of follow-up. Patients who were malnourished (PG-SGA-B and C) had an increased risk of mortality (Hazard Ratio [HR]: 3.12, 95% CI: 1.23 - 7.86) as compared to those who were well nourished (PG-SGA-A). Patients from rural areas had an increased risk of mortality (HR: 6.99, 95% CI: 2.07 - 23.58) compared to patients from urban areas. CONCLUSION: In the context of developing country setting and COVID19 outbreak, malnutrition significantly decreases cervical cancer survival. A thorough nutrition assessment using scored PG-SGA is needed.

Prevalence of high bloodpressure, hyperglycemia, dyslipidemia, metabolic syndrome and their determinants in Ethiopia: Evidences from the National NCDs STEPS Survey, 2015.

The prevalence of diabetes, dyslipidemias, and high blood pressure is increasing worldwide especially in low and middle income countries. World Health Organization has emphasized the importance of the assessment of the magnitude of the specific disease in each country. We determined the prevalence and determinant factors of high blood pressure, hyperglycemia, dyslipidemias and metabolic syndrome in Ethiopia. A community based survey was conducted from -April to June 2015 using WHO NCD STEPS instrument version 3.1. 2008. Multistage stratified systemic random sampling was used to select representative samples from 9 regions of the country. A total of 10,260 people aged 15-69 years participated in the study. Blood pressure (BP) was measured for 9788 individuals. A total of 9141 people underwent metabolic screening. The prevalence of raised blood pressure (SBP ≥140 and/or DBP ≥ 90 mmHg) was 15.8% (16.3% in females and 15.5% in males). The prevalence of diabetes mellitus (FBS ≥ 126 mg /dl) including those on medication was 3.2% (3.5% males and 3.0% females). The prevalence of impaired fasting glucose was 9.1% with ADA criteria and 3.8% with WHO criteria. Hypercholesterolemia was found in 5.2%, hypertriglyceridemia in 21.0%, high LDL cholesterol occurred in 14.1% and low HDL cholesterol occurred in 68.7%. The prevalence of metabolic syndrome using IDF definition was 4.8% (8.6% in females and vs. 1.8% in males). Advanced age, urban residence, lack of physical exercise, raised waist circumference, raised waist hip ratio, overweight or obesity, and total blood cholesterol were significantly associated with raised blood pressure (BP) and diabetes mellitus. Increased waist- hip ratio was an independent predictor of raised blood pressure, hyperglycemia and raised total cholesterol. Our study showed significantly high prevalence of raised blood pressure, hyperglycemia and dyslipidemia in Ethiopia. Community based interventions are recommended to control these risk factors.
