Summary With the rapid popularity and increasing numbers of E-cigarette (EC) users, debates on possible health risks and regulation of EC products have attracted attention in public. As a useful means to help assessing the risks of EC consumers, puffing topography studies have come to be an important tool globally. In this paper, a cross-sectional epidemiological study on puffing topography of 511 EC consumers in four cities of China was conducted in January 2018. Data acquisition was based on a questionnaire and a Clinical Research Support System (CReSS) Pocket device for the smoking behavior recording. The results showed that EC consumers in the four cities were mainly young males, most of whom preferred tank systems with zero or low nicotine concentrations (1–5 mg/mL) in the liquid. The average puff volume, puff duration and inter-puff interval (IPI) were 87.2 mL, 1.97 s and 22.0 s, respectively. The factors that may have affected puffing topography such as product type, nicotine concentration, using time, smoking status and battery power were studied. The results suggest that the EC product type and the concentration of nicotine in EC liquids were the main factors that affected the puffing topography of the users. This study was the first study on the puff topography of Chinese EC consumers with a large number of participants. The results may not only help to more deeply understand smoking behavior and to better assess the potential risks for the EC users, but they may also supply useful information for the development of smoking machine regimes for ECs.

Abstract Background Secondhand smoke exposure is responsible for over half a million premature deaths. With regulation now reducing smoking in most public enclosed spaces, one major source of indoor exposure remains the home environment. Home smoking bans (HSBs) are household rules that restrict smoking from certain (partial HSB) or all areas (complete HSB). Recent data suggest growing trends of HSB adoption over time, but it is not known whether time trends vary according to household characteristics. Objectives The aim of this study is to examine changes in the prevalence of HSB in six European cities between 2013 and 2016, according to socioeconomic characteristics of the household and smoking behavior of household members. Methods Data were collected in all schools participating in both waves of SILNE study in 6 European cities. A self-administered questionnaire was used, targeting students age 14 to 16 (n = 22,326). Students reported their parents’ smoking status and if there was a HSB at their home. Detailed information on socio-economic characteristics were collected as well. Results Between 2013 and 2016 the percentage of households with a complete HSB increased from 51.5% to 53.1%, while partial HSB increased from 30.7% to 32.1%. The prevalence of HSB increased in Hannover (G), Latina (I), Amersfoort (N) and Coimbra (P), whereas decreased in Namur (B) and Tampere (F). Socioeconomic differences in HSB were reduced, with larger increases in HSB in households with a lower parental educational level. Increases in HSB were observed among intact households, those without migration background and those with non-smoking parents. Conclusions The increase in the prevalence of HSB observed in most cities and throughout a variety of household types and characteristics between 2013 and 2016 may reflect the effect of smoking denormalization in different social contexts. Further actions of the tobacco control community should target the most vulnerable groups. Key messages The percentage of households with a complete HSB increased between 2013 and 2016 in 4 out of 6 European cities. Increases in the prevalence of HSB over time were observed across all socio-economic groups.

Background: No study has reported the relationship between smoking status with chronic obstructive pulmonary diseases (COPD) and metabolic syndrome (MetS) in Kazakhstan. The aim of this study was to assess the associations between health outcomes, including COPD, MetS, respiratory symptoms, and functional incapacity, with the cigarette smoking status. Methods: The cross-sectional study recruited 500 smokers, 200 ex-smokers, and 200 never-smokers aged 40-59 in Almaty, Kazakhstan. Questions assessed socio-demographic, clinical characteristics, and smoking behavior. Blood glucose and lipid profiles were determined after overnight fasting. COPD was defined according to the GOLD 2017 statement. Respiratory symptoms and functional incapacity were assessed by the COPD Assessment Test (CAT) and 6-min walk test (6MWT), respectively. Logistic regression models were used to assess the associations. Results: The prevalence of COPD among smokers, ex-smokers and never-smokers were 5.5%, 3.0% and 3.0%, respectively. Respiratory symptoms based on CAT were more prevalent among smokers (42.8%) as compared to ex-smokers (42.8% vs 17.0%; aOR 3.43, 95% CI 2.25–5.23) and never-smokers (42.8% vs 12.5%; aOR 5.44, 95% CI 3.42–8.65). Current smokers were more likely to walk less than 450 meters during 6MWT as compared to never-smokers (16.5% vs 5.0%; aOR 3.72, 95% CI 1.86–7.44). No significant association was found between the smoking status with COPD and MetS.  Conclusions: Respiratory symptoms are common among the current smokers, even if most of them had preserved pulmonary function defined by spirometry.

Summary The use of electronic cigarettes (ECs) has grown exponentially over the past few years in China. To obtain the basic information of Chinese EC users, a questionnaire survey was performed to collect the data that describe characteristics of study populations, including daily usage, consumption preference, and risk perception. Volunteers were recruited from Beijing, Shanghai, Guangzhou, and Shenzhen cities of China. In total, among the 511 participants that were included in the analysis, 491 participants (95%) used refillable ECs in the past 3 months. There was a strong association between EC use and traditional cigarette smoking. The majority of participants were dual users and the number of cigarettes smoked decreased with the use of ECs. After using an EC, 20.7% of conventional cigarette smokers attempted to quit smoking. Young people were the primary users across all geographic locations. Specifically, the daily usage for the participants who were 18–39 years old, was higher than those over 40 years old. The majority of participants (59.9%) preferred fruit flavors and 57.8% of them used 1–5 mg/mL nicotine-concentration liquids. Most EC users are motived to quit smoking, and 74.6% claimed that the ECs had no irritant effect on the oral cavity. A total of 50.5% of family members of the study participants reported an improvement of health status while the participants used ECs instead of traditional cigarettes. Overall, the results of this Chinese survey indicate that the per-day cigarette consumption of the dual users decreased whereas their proportion of smokers of low-“tar” cigarettes increased.

AbstractThe non-dipping pattern is nighttime systolic blood pressure (SBP) fall of less than 10%. Several studies showed that the non-dipping pattern, increased mean platelet volume (MPV), and platelet distribution width (PDW) are associated with elevated cardiovascular risk. Hypertensives with the non-dipping pattern have higher MPV than the dippers but this relationship was never investigated among people with type 1 diabetes mellitus (T1DM). This study aimed to investigate the association between the central dipping pattern and platelet morphology in T1DM subjects. We measured the central and brachial blood pressure with a validated non-invasive brachial oscillometric device—Arteriograph 24—during twenty-four-hour analysis in T1DM subjects without diagnosed hypertension. The group was divided based on the central dipping pattern for the dippers and the non-dippers. From a total of 62 subjects (32 males) aged 30.1 (25.7–37) years with T1DM duration 15.0 (9.0–20) years, 36 were non-dippers. The non-dipper group had significantly higher MPV (MPV (10.8 [10.3–11.5] vs 10.4 [10.0–10.7] fl; p = 0.041) and PDW (13.2 [11.7–14.9] vs 12.3 [11.7–12.8] fl; p = 0.029) than dipper group. Multivariable logistic regression revealed that MPV (OR 3.74; 95% CI 1.48–9.45; p = 0.005) and PDW (OR 1.91; 95% CI 1.22–3.00; p = 0.005) were positively associated with central non-dipping pattern adjusting for age, sex, smoking status, daily insulin intake, and height. MPV and PDW are positively associated with the central non-dipping pattern among people with T1DM.

This cross-sectional study aimed to investigate the association between hyperuricemia and the frequency of coffee, tea, and soft drink consumption, based on data from the Korean Genome and Epidemiology Study (KoGES) (2004–2016). We used the KoGES health examinee data, obtained from urban residents aged ≥ 40 years. Information on the participants’ medical history, nutrition (total calorie, protein, fat, and carbohydrate intake), frequency of alcohol consumption, smoking status, household income, and frequency of coffee/green tea/soft drink intake was collected. A logistic regression model was used to analyze the data. Subgroup analyses were performed according to the participant’s age and sex. Among 173,209 participants, there were 11,750 and 156,002 individuals with hyperuricemia and non-hyperuricemia controls, respectively. In an adjusted model, frequent coffee and green tea consumption did not increase the risk of hyperuricemia, compared to the “no intake” reference group. However, an adjusted odds ratio of hyperuricemia was 1.23 (95% confidence interval, 1.11–1.35, p < 0.001) for participants who reported consuming soft drinks ≥ 3 times per day, compared to the respective “no drink” reference group. Even after adjusting for nutritional and sociodemographic factors, frequent soft drink intake was associated with an increased risk of hyperuricemia. Meanwhile, neither coffee nor green tea intake was associated with an increased risk of hyperuricemia.

Abstract Background Breast cancer is the most common cancer among women and the second leading cause of cancer death globally. Since early diagnosis is crucial to reducing mortality, high levels of knowledge regarding general information, risk factors, and symptoms are required among healthcare professionals to deliver breast cancer care. This study aimed to determine Syrian medical students’ knowledge about breast cancer in the fields of general knowledge, common clinical features, and risk factors. Methods This cross-sectional study was conducted at the Syrian Private University in October 2019 (Breast Cancer Awareness Month), Damascus, during the Syrian war crisis. Data were collected through self-administered surveys and analyzed using the Statistical Package for Social Sciences version 25.0 (SPSS Inc., United States). The chi-square test was applied to assess the relationship between the level of knowledge and gender. One way analysis of variance was performed to assess the overall differences in mean knowledge score by study year, GPA, mother’s education, and source of information. Unpaired Student’s T-test was used to analyze the differences in mean knowledge scores (continuous variable) based on smoking status and alcohol consumption. Results Of 320 students, 301 completed the questionnaire (response rate = 94.0%), of which 179(59.5%) were males. The study revealed above-average knowledge scores (total mean = 68.4%) regarding breast cancer, general information (71.9%), common clinical features (71.6%), and risk factors (71.6%). Clinical students (4th, 5th, and 6th years) scored higher compared with pre-clinical students (1st, 2nd, and 3rd years). Conclusion This study showed above-average knowledge scores regarding breast cancer. More efforts to correct misinformation, through reassessing the university curriculum and promoting awareness about breast cancer are required.

BACKGROUND: Low Health Literacy (HL) and Nutrition Literacy (NL) are associated with serious negative health outcomes. OBJECTIVES: The aim of this study was to investigate certain lifestyle factors and obesity, in relation to HL and NL. METHODS: This cross-sectional study was conducted in the urban area of the Attica region, in Greece. The sample consisted of 1281 individuals, aged ≥18 years. HL, NL sociodemographic characteristics and lifestyle factors (physical activity, smoking status, alcohol consumption,) were assessed. Mann-Whitney U, the Kruskall Wallis, Pearson chi-square tests and multiple linear regression models were used. RESULTS: Linear regression analysis has shown that smoking, alcohol consumption and physical activity, were associated with HL levels (–1.573 points for ex-smokers in comparison to smokers, p = 0.035, –1.349 points for alcohol consumers in comparison to non-consumers, p = 0.006 and 1.544 points for physically active individuals to non-active, p = 0.001). With respect to NL levels, it was also not associated with any of these factors. Obesity was not associated with HL and NL levels. CONCLUSIONS: Certain lifestyle factors, including physical activity, are predicting factors of HL levels, in Greek adults. The results contribute to the understanding of the relationship between lifestyle factors and HL and should be taken into account when HL policies are designed.

AbstractObjectivesThis study aimed to estimate the extent of smoking experience among high and middle school adolescents in Southern Tunisia and to delineate its potential associated factors.MethodsWe conducted a cross-sectional study among middle and high school-adolescents in the governorate of Sfax, South of Tunisia in the 2017–2018 school-years. A questionnaire was anonymously administered to a representative sample of 1,210 school-adolescents randomly drawn.ResultsThe mean age of the school-adolescents was 15.6 ± 4.2 years. The prevalence of lifetime smoking was 16.7% (95% CI=[14.7–18.8%]) (boys 32.6%; girls 5.9%;p<0.001). Among the respondents, 13.9% (95% CI=[11.9–15.8%]) were current smokers. In multivariate logistic regression analysis, independent associated factors of current smoking were male gender (Adjusted (AOR)=10.2; p<0.001), 16–17 and 18–19-year age-groups (AOR=2; p=0.005 and AOR=2.6; p=0.001, respectively), below average academic performance (AOR=5.2; p=0.012), divorced parents (AOR=3.9; p=0.007), family monthly income ≥800 dollars (AOR=2.1; p=0.001), having a part time job (AOR=3.9; p<0.001) and a perceived high stress level (AOR=1.98; p=0.008). Secondhand smoke (AOR=1.8; p=0.011) and concomitant alcohol drink (AOR=14.56; p<0.001) were independent predictors of current smoking, while high education level of the father was independently associated with lower prevalence of current smoking (AOR=0.17; p<0.001).ConclusionThe prevalence of lifetime and current smoking were relatively high in Southern Tunisian middle and high schools. Multilevel influences on youth smoking behavior had been identified, which reflected the need to conceive appropriate school interventions and effective antismoking education program.

Background:This survey aims to assess the prevalence of physical activity among adult Lebanese, and to report the relationship between sociodemographic variables and physical activity behavior, highlighting the correlates discouraging people to carry out physical activity.Methods:A cross-sectional study using an anonymous self-reported questionnaire was conducted on 346 adults from four Lebanese districts. Demographic characteristics, physical activity, smoking status, alcohol consumption, and medical history were obtained.Results:Prevalence of physical activity among Lebanese adults was 55.5% (192/346). Age, BMI, marital status, medical history, occupation, educational level, and smoking were significantly associated with physical activity (P < .05). Inactive obese participants were about three times more likely to report hypertension and diabetes than inactive normal weight participants (P = .013). BMI was significantly higher among inactive participants (P = .014).Conclusion:Physical activity among Lebanese adults was comparable to other populations. Married, non–office workers, and smokers were the main correlates of physical inactivity in Lebanese adulthood.
