Lower Levels Of Smoking Research Articles

Work-, lifestyle-, and health-related factors among women and men working in the emergency medical services

Objectives. This study aimed to describe work-, lifestyle-, and health-related factors among ambulance personnel, and to analyse differences between women and men. Methods. The cross-sectional study (N = 106) included self-reported and objective measures of work, lifestyle, and health in 10 Swedish ambulance stations. The data collection comprised clinical health examination, blood samples, tests of physical capacity, and questionnaires. Results. A high proportion of the ambulance personnel reported heavy lifting, risk of accidents, threats and violence at work. A low level of smoking and alcohol use, and a high level of leisure-time physical activity were reported. The ambulance personnel had, on average, good self-rated health, high work ability and high physical capacity. However, the results also showed high proportions with risk factors for cardiovascular disease (CVD), e.g., high blood pressure, and high levels of blood lipids. More women than men reported high work demands. Furthermore, women performed better in tests of physical capacity and had a lower level of CVD risk factors. Conclusions. Exposure to work-related factors that might affect health was common among ambulance personnel. Lifestyle- and health-related factors were somewhat contradictory, with a low proportion reporting lifestyle-related risk factors, but a high proportion having risk factors for CVD.

Reflection of prenatal exposure to wildfire smoke on reduced birth weight in 2015-2019

Wildfire smoke contains many different types of air pollutants which are cause for concern. Studies on epidemiology have identified correlations between PM2.5 exposure to wildfire smoke and mortality, respiratory and cardiovascular morbidities, and may result in a reduction in birth weight. However, evidence from Indonesia is limited. For this study, a retrospective cohort epidemiological study was undertaken to quantify the Indonesian population’s exposure to wildfire-PM2.5. We present 9652 (88%) records of newborns to identify an association between fire-sourced PM2.5 and birth weight in Palangka Raya, Indonesia from 2015 to 2019. On an annual basis, geospatial, and season variations in wildfire-PM2.5 concentrations were observed using a satellite-based dataset from CAMS and used for gestational exposure to wildfire smoke. Applying a general linear model with birth weight (yi) as a continuous outcome, the relationship between PM2.5 exposure and low birth weight was examined. In addition, the binary outcome of low birth weight was analysed. A statistically significant difference in the birth weight reduction between infants delivered to mothers exposed to high levels of wildfire smoke and those exposed to low levels of wildfire smoke was observed over the entire time frame (2015-2019) (ρ-value < 0.001). In comparison to infants born to mothers exposed to lower concentrations, the birth weight of infants delivered to mothers exposed to high concentrations of PM2.5 in the third trimester decreased by 19.96%. A 1.9% reduction in birth weight could be caused by exposure during the fire-prevalent in the first trimester of pregnancy (ρ-value < 0.001). Since an estimation model predicted a 10 g/m3 increase in PM2.5 exposure between the first and last trimesters of pregnancy, variations in the second trimester did not significantly affect the association (ρ-value = 0.761). This emphasizes the significance of foetal development during these two trimesters. Exposure to pollution from wildfires contributes significantly to the global burden of newborns’ birth weight.

Impact of Smoke from Wheat, Oat, and Clover Stubble Burning on Cabernet Sauvignon Grapes and Wine

Background and Aims. Stubble burning is an agricultural practice employed by some grain growers to prepare farmland for sowing and/or to control weeds and pests. Grapegrowers and winemakers have questioned whether the resulting smoke can contaminate grapes in nearby vineyards. This study therefore sought to determine the potential for smoke from three different stubble burns to taint grapes and wine. Methods and Results. Excised bunches of mature Cabernet Sauvignon grapes were exposed to smoke from prescribed burning of wheat, oat, and Balansa clover stubble windrows. Environmental sensors monitored the concentration of particulate matter as a measure of smoke density, while chemical and sensory analysis established the extent to which grapes and wine were tainted by smoke. Only grapes that were positioned among the burning wheat windrows or downwind, but in close proximity (∼200 m) to the oat stubble burn, were exposed to sufficient quantities of smoke to result in a detectable concentration of volatile phenols (up to 12 µg/kg), as chemical markers of smoke taint. These grapes yielded wines with two to threefold higher volatile phenol concentrations (up to 18 µg/L) than other wines, including the control wine, and low intensity, but perceptible smoke-related sensory attributes, indicative of low-level smoke taint. Conclusions. Chemical and sensory analyses suggest the risk of smoke taint from stubble burning is low, except where vineyards are immediately downwind and/or prolonged or repeated smoke exposure occurs. However, stubble moisture content and prevailing weather conditions affect smoke density and dispersion, and will therefore affect the potential for smoke contamination by grapes. Significance of the Study. This study will assist colocated grain growers and grape and wine producers to undertake commercial operations, without negatively impacting one another.

Trends in adolescent secondhand smoke exposure at home over 15 years in Korea: Inequality by parental education level.

Low parental education level and parental smoking are major risk factors for household secondhand smoke (SHS) exposure among adolescents. We investigated the trend in household SHS exposure according to sex, school, and parental education level to determine whether the decline in household SHS exposure over time depends on parental education level. We used cross-sectional Korea Youth Risk Behavior datasets (2006-2020; 806829 subjects were eligible). We applied binary logistic regression to assess household SHS exposure trends and evaluated the interaction between period and parental education level. Household SHS exposure over 15 years has declined. The difference (0.121) was the smallest for male middle school students with low-educated parents. The slope for the estimated probability of household SHS exposure among students with high-educated parents was steeper than that for those with low-educated parents, except for female high school students (difference=0.141). Students with low-educated parents were at higher risk of household SHS exposure (male middle school students, adjusted odds ratio, AOR=1.52; 95% CI: 1.47-1.56; male high school students, AOR=1.42; 95% CI: 1.38-1.47; female middle school students, AOR=1.62; 95% CI: 1.58-1.67; female high school students, AOR=1.62; 95% CI: 1.57-1.67). The interaction between parental education level and period was significant. We also found a significant interaction between parental education level and parental smoking (other × present interaction, AOR=0.64; 95% CI: 0.60-0.67; low-low × present interaction, AOR=0.89; 95% CI: 0.83-0.95). Changes in parental education level over time mainly contributed to changes in adolescents' household SHS exposure. Adolescents with low-educated parents were at higher risk of household SHS exposure, with a slower decline. These gaps must be considered when creating and implementing interventions. Campaigns and community programs to prevent household SHS need to be emphasized among vulnerable adolescents.

A Systematic Investigation on the Influence of Intumescent Flame Retardants on the Properties of Ethylene Vinyl Acetate (EVA)/Liner Low Density Polyethylene (LLDPE) Blends.

Because of their high filler loadings, commercial-grade clean flame-retardant materials have unstable mechanical properties. To address this issue, intumescent polymers can be used to develop clean flame retardants with very low levels of smoke and toxicity generation. An intumescent flame retardant (IFR) system composed of red phosphorus (RP), zinc borate (ZB), and a terpolymer of ethylene, butyl acrylate, and maleic anhydride (EBM) was used to prepare EVA (ethylene-vinyl acetate) and EVA/LLDPE (linear low-density polyethylene) composites; their mechanical and flammability properties were systematically investigated. The limiting oxygen index (LOI) of the EVA/LLDPE (as base material) composite containing RP and ZB mixed with nonhalogenated flame retardant, mainly magnesium hydroxide (MH) and coadditives, including processing aids and thermal stabilizers, was established. RP was found to have little effect on the tensile properties of EVA/LLDPE 118W/120 phr flame-retardant (MH + RP) composites. There was a minute difference in the effective trend of RP between tensile strength and elongation at break. Following the addition of ZB, the elongation at break of the composites gradually decreased with increasing RP content and then leveled off when the RP content was over 10 phr. Mechanical properties (elongation at break and tensile strength) can be best maintained at below 10 phr content of RP. The mechanical properties decreased with lower amounts of EBM content. In addition, flame retardancy increased when the EBM content decreased. The findings further revealed that MH and RP have poor compatibility, yielding poor mechanical properties. The LOI greatly increased with RP content, even though the total content of flame retardants (main + intumescent flame retardant) was the same in all formulations. Only over 5 phr RP content formulations passed V-0 of the UL-94 test. When under 5 phr, the RP content formulations did not pass V-0 of the UL-94 test.

A research study on the combustion and performance of Mosambi peel pyro oil diesel blend with methanol enrichment in diesel engine

ABSTRACT Because of their great capability and consistent quality, Diesel engines are commonly employed in Industrial regions, Transportation sectors, and Agricultural fields. The main disadvantage of this engine is the excessive amount of smoke and nitrogen oxide emissions. As a result, Mosambi Peel Pyro oil (MPO) was blended in varying quantities with straight diesel. Methanol enrichment was used to test D90MPO10 (10% MPO +90% Diesel), D90MPO10M21 (10% MPO +90% Diesel +21% Methanol), and D90MPO10M22 (10% MPO +90% Diesel +22% Methanol)Oil parameters.The ultimate, proximate, and FTIR analyses, as well as viscosity, density, flash point, and fire point, are estimated. D90MPO10, D90MPO10M21, and D90MPO10M22 are diesel engine fuels, and D90MPO10M22‘s combustion and emission performance are investigated. It was shown that using D90MPO10 as pilot fuel and methanol as an induction fuel in diesel engines resulted in lower smoke levels (3.5%) and increased thermal efficiency (2.5%) with no significant Performance Degradation.

Health‐related behaviours and weight status of expectant fathers

ObjectiveLittle attention has been given to the health status and lifestyle behaviours of expectant fathers. This study aimed to examine health‐related variables in a cohort of expectant fathers to identify potential focus areas for interventions designed to optimise health and wellbeing outcomes in this group. MethodsPartners of pregnant women who accessed antenatal services at a large maternity unit in a Western Australian hospital were recruited as part of the ORIGINS Project. Analyses were conducted on data from 498 expectant fathers who were primarily of mid and high socioeconomic status. ResultsParticipants reported relatively low levels of smoking and alcohol consumption and higher physical activity compared to national averages. Weight status was consistent with population norms for adult males: 76% were overweight or obese and 62% had a waist girth ≥94cm. ConclusionsExpectant fathers may benefit from health interventions, especially in relation to managing their weight during this phase of their lives and beyond. Implications for public healthPregnancy represents a valuable opportunity to engage fathers‐to‐be in health interventions. Given identified links between paternal weight status and offspring outcomes, interventions focusing on achieving and maintaining a healthy weight among expectant fathers could be beneficial for families.

Identifying prospective subpopulations of combustible and electronic cigarette dual users in the United States via finite mixture modeling.

To identify subpopulations of dual users of combustible and electronic cigarettes using current smoking and vaping behaviors. Secondary analysis of baseline data from a randomized controlled trial testing a smoking cessation intervention for dual users. Finite mixture modeling of frequency, quantity, and dependence on combustible and electronic cigarettes was used to identify classes. Demographics and additional smoking and vaping variables were used to further characterize the classes. United States. A total of 2896 adults who smoked weekly for the past year and vaped weekly for the past month. Self-report baseline measures assessed demographics and smoking and vaping behaviors and characteristics including days of use per week, frequency of use within a day, time to first use after waking, urges to smoke, smoking cessation motivation, self-efficacy to abstain from smoking, months since vaping initiation, reasons for initiating and maintaining vaping, and future plans to stop vaping. Eight probabilistic classes were identified and well-defined (relative entropy = 0.95, Lo-Mendell-Rubin adjusted likelihood ratio test P < 0.0001; class probabilities 0.89-0.97). In general, classes crossed two levels of smoking with four levels of vaping. The largest class (31%) had relatively high levels of smoking (72% daily, 56% 11+ cigarettes per day [CPD], 96% within 30 minutes of waking) and vaping (74% daily, 100% 20+ electronic-CPD, 74% <30 minutes). The next largest class (27%) had relatively high levels of vaping (93% daily, 100% 20+ electronic-CPD, 82% <30 minutes) and very low levels of smoking (28% daily, 12% 11+ CPD, 0% <30 minutes). The six smaller classes (3%-13%) also had distinct smoking and vaping behaviors. All eight classes exhibited distinguishing characteristics beyond current smoking and vaping behaviors. Dual users of combustible and electronic cigarettes are not a homogeneous population, having eight well-defined prospective subpopulations.

Understanding longevity in Hong Kong: a comparative study with long-living, high-income countries

Since 2013, Hong Kong has sustained the world's highest life expectancy at birth-a key indicator of population health. The reasons behind this achievement remain poorly understood but are of great relevance to both rapidly developing and high-income regions. Here, we aim to compare factors behind Hong Kong's survival advantage over long-living, high-income countries. Life expectancy data from 1960-2020 were obtained for 18 high-income countries in the Organisation for Economic Co-operation and Development from the Human Mortality Database and for Hong Kong from Hong Kong's Census and Statistics Department. Causes of death data from 1950-2016 were obtained from WHO's Mortality Database. We used truncated cross-sectional average length of life (TCAL) to identify the contributions to survival differences based on 263 million deaths overall. As smoking is the leading cause of premature death, we also compared smoking-attributable mortality between Hong Kong and the high-income countries. From 1979-2016, Hong Kong accumulated a substantial survival advantage over high-income countries, with a difference of 1·86 years (95% CI 1·83-1·89) for males and 2·50 years (2·47-2·53) for females. As mortality from infectious diseases declined, the main contributors to Hong Kong's survival advantage were lower mortality from cardiovascular diseases for both males (TCAL difference 1·22 years, 95% CI 1·21-1·23) and females (1·19 years, 1·18-1·21), cancer for females (0·47 years, 0·45-0·48), and transport accidents for males (0·27 years, 0·27-0·28). Among high-income populations, Hong Kong recorded the lowest cardiovascular mortality and one of the lowest cancer mortalities in women. These findings were underpinned by the lowest absolute smoking-attributable mortality in high-income regions (39·7 per 100 000 in 2016, 95% CI 34·4-45·0). Reduced smoking-attributable mortality contributed to 50·5% (0·94 years, 0·93-0·95) of Hong Kong's survival advantage over males in high-income countries and 34·8% (0·87 years, 0·87-0·88) of it in females. Hong Kong's leading longevity is the result of fewer diseases of poverty while suppressing the diseases of affluence. A unique combination of economic prosperity and low levels of smoking with development contributed to this achievement. As such, it offers a framework that could be replicated through deliberate policies in developing and developed populations globally.

Pattern of growth development of premature children at the age of two and three years in Alexandria, Egypt [Part II

Thisis the second part of a paper on a study conducted in Alexandria on 68 premature children. Controls were full-term children, double the number of prematures, and matched by age and sex. The first part presented differences in growth and development in relation to prematurity. This part deals with risk factors for prematurity. The study revealed that low educational level of fathers and parental smoking were significant risk factors for prematurity. The mean age of both parents and mothers’ gravidity were significantly higher for prematures. Other risk factors were identified. Mothers with diabetes and chronic nephritis were more likely to have a premature child

Long-term cerebrovascular dysfunction in the offspring from maternal electronic cigarette use during pregnancy.

Electronic cigarettes (E-cigs) have been promoted as harm-free or less risky than smoking, even for women during pregnancy. These claims are made largely on E-cig aerosol having fewer number of toxic chemicals compared with cigarette smoke. Given that even low levels of smoking are found to produce adverse birth outcomes, we sought to test the hypothesis that vaping during pregnancy (with or without nicotine) would not be harm-free and would result in vascular dysfunction that would be evident in offspring during adolescent and/or adult life. Pregnant female Sprague Dawley rats were exposed to E-cig aerosol (1 h/day, 5 days/wk, starting on gestational day 2 until pups were weaned) using e-liquid with 0 mg/mL (E-cig0) or 18 mg/mL nicotine (E-cig18) and compared with ambient air-exposed controls. Body mass at birth and at weaning were not different between groups. Assessment of middle cerebral artery (MCA) reactivity revealed a 51%-56% reduction in endothelial-dependent dilation response to acetylcholine (ACh) for both E-cig0 and E-cig18 in 1-mo, 3-mo (adolescent), and 7-mo-old (adult) offspring (P < 0.05 compared with air, all time points). MCA responses to sodium nitroprusside (SNP) and myogenic tone were not different across groups, suggesting that endothelial-independent responses were not altered. The MCA vasoconstrictor response (5-hydroxytryptamine, 5-HT) was also not different across treatment and age groups. These data demonstrate that maternal vaping during pregnancy is not harm-free and confers significant cerebrovascular health risk/dysfunction to offspring that persists into adult life. NEW & NOTEWORTHY These data established that vaping electronic cigarettes during pregnancy, with or without nicotine, is not safe and confers significant risk potential to the cerebrovascular health of offspring in early and adult life. A key finding is that vaping without nicotine does not protect offspring from cerebrovascular dysfunction and results in the same level of cerebrovascular dysfunction (compared with maternal vaping with nicotine), indicating that the physical and/or chemical properties from the base solution (other than nicotine) are responsible for the cerebrovascular dysfunction that we observed.

Estimating the impact of state cigarette tax rates on smoking behavior: Addressing endogeneity using a natural experiment

IntroductionCigarette excise taxes are a well-established policy lever for reducing tobacco use. However, estimating the effect of taxes on smoking behavior can be confounded by endogeneity concerns such as selection. This study leverages a unique natural experiment –compulsory relocation of U.S. military service members to installations – to estimate the relationship between state cigarette taxes and smoking behavior without concerns about selection into environments. MethodsThe current study uses data from the Department of Defense’s 2011 Health-Related Behaviors Survey and 2011 state cigarette excise taxes from the CDC STATE System. Logistic and Poisson regression analyses estimate the cross-sectional associations between state cigarette excise taxes and the following smoking behaviors: current cigarette smoking, frequency of smoking, heaviness of consumption, and cigarette cessation among individuals who smoked while at the current installation. ResultsHigher taxes are associated with lower odds of current cigarette smoking (AOR = 0.94; 95 % CI: 0.89−0.98), fewer smoking days per month among current cigarette smokers (IRR = 0.98, 95 % CI 0.97−0.996), and higher likelihood of quitting smoking among individuals who had smoked at their current installation (AOR = 1.14, 95 % CI 1.05–1.25). Taxes are not associated with the number of cigarettes smoked per day among current smokers. ConclusionsExogenous assignment to installations in states with higher cigarette taxes is associated with lower likelihood of smoking and greater likelihood of quitting. Findings provide novel evidence in support of a causal impact of cigarette taxes on lower smoking levels among adults.

Adaptation of the Young Adults’ Cigarette Dependence (YACD) Scale for the development and validation of the Adolescent Cigarette Dependence Scale (ACDS)

Vulnerable adolescents may lose control over cigarette use within a day or two after smoking their first cigarette, as nicotine dependence (ND) symptoms may appear before actual daily smoking and usually occur at low levels of daily smoking. Moreover, smoking can cause illnesses and promote other types of substance abuse. Therefore, it was deemed essential to adapt the Young Adults’ Cigarette Dependence (YACD) Scale to develop and validate the Adolescent Cigarette Dependence Scale (ACDS) in Lebanese adolescents and evaluate whether cumulative cigarette smoking is associated with nicotine dependence and symptoms of dependence. A cross-sectional study was carried out between August and September 2020, during the partial sanitary lockdown imposed by the government to limit COVID-19, coinciding with the summer holidays for most Lebanese. The total sample consisted of 564 community-dwelling adolescents aged 13 to 18. A factor analysis was performed using a varimax rotation. The Kaiser-Meyer-Olkin (KMO) measurement of sampling adequacy and Bartlett’s sphericity test were appropriate. The factors retained corresponded to Eigenvalues > 1. Cronbach’s alpha value represented the internal consistency of the scale. The Hooked on Nicotine Checklist (HONC) was used to screen for dependence symptoms. All items of the YACD were extracted, except for items 4 (smoking to concentrate at work) and 18 (smoking as a habit), which yielded a three-factor solution (factor 1 = smoking patterns; factor 2 = positive and negative reinforcements; factor 3 = smoking cessation) with Eigenvalues > 1 (variance explained = 56.18%; KMO = 0.784; Bartlett’s sphericity test p < 0.001; αCronbach = 0.875). The newly generated scale was termed Adolescent Cigarette Dependence Scale (ACDS) and consisted of 19 items. Higher ACDS scores (higher cigarette dependence) were significantly associated with higher HONC scores (higher symptoms of dependence) (rho = 0.647; p < 0.001). Having deceased (B = 8.54) or divorced (B = 4.26) parents and higher cumulative cigarette smoking (B = 0.29) were significantly associated with higher ACDS scores. Higher cumulative cigarette smoking (B = 0.05) was significantly associated with higher HONC scores due to cigarettes. This study could validate a new tool to evaluate nicotine dependence among Lebanese adolescents, the Adolescent Cigarette Dependence Scale (ACDS). This version adapted from the Young Adults’ Cigarette Dependence (YACD) Scale is reliable and valuable and correlates well with other scales, such as the HONC. However, further studies are necessary to improve this instrument, adding new questions useful for the diagnosis and evaluation of cigarette dependence.

Пути решения проблем, связанных с подростковым материнством (научный обзор)

The World Health Organization, arguing for the need to invest in the health and development of adolescents, notes that its work helps to improve the health and well-being of millions of adolescents who experience problems such as depression, anemia, HIV infection, promotes the introduction of a healthy lifestyle, prevention of health problems that may occur in adulthood (for example, cardiovascular diseases and lung cancer caused by low levels of physical activity and smoking, problems originating in adolescence). Investments in adolescent health will also prevent problems in the next generations, in particular, such as prematurity and low body weight in children born to very young mothers. Among the significant factors contributing to the achievement of low childbearing activity in adolescence, the low level of abortions and HIV infection among young people, the fact was especially emphasized that it is in these countries that parents and the public positively perceive the sexuality of young people, and sexual relations are considered a logical and natural continuation of a long-term relationship between a young man and a girl, a serious component of emotionally healthy adulthood. The sexual behavior of adolescents in developed European countries is primarily a matter of harmonious development and public health. Most adults do not consider adolescent sex an issue as long as the “rules of protected sex” are maintained. Experts of the World Health Organization, in cooperation with UNICEF headquarters, have developed an orientation program “Adolescent Health”. The presence of the phenomena of adolescent pregnancy and fertility, the negative consequences that may accompany these phenomena and the possibility of reducing their level indicate the need to develop appropriate programs, among which early pregnancy prevention programs should take an important place. Social readaptation of young mothers should take into account the following aspects: social, psycho-correctional, medical, career guidance, legal.

A Community Based Cross Sectional Study to Estimate the Prevalence and Associated Factors of Hypertension in Rural Nepal

Background Hypertension is a major global public health problem because of its high prevalence as it significantly increases the risk of heart attack, stroke, kidney failure and blindness. Epidemiological shift in prevalence of non-communicable diseases have been observed in Nepal and it is also evident that hypertension and related complications are major contributors to death and disability in Nepal. Objective To estimate the prevalence and explore the associated factors of hypertension in study population. Method A community based cross-sectional study was conducted in rural population of Nepal with multistage sampling design. A total of 422 participants aged 18 to 65 years of age participated in the study. The information was obtained using pretested questionnaire which included demographic information of individuals and other risk factors like alcohol and tobacco use, physical activity. Anthropometric measurements and blood pressure was recorded and hypertension was defined as per JNC VII criteria. Result The overall prevalence of hypertension was 27.7% (male: 32.7%, female: 19.8%). Mean systolic and diastolic BP were 123.79 ± 12.46 mmHg and 81.56 ± 8.32 mmHg, respectively. Age (eldest age group, AOR=4.92: CI: 1.24-19.46), participants with lower level of education (higher education, AOR=0.173: CI: 0.05-0.53), ethnicity (Janajatis, AOR=2.85: CI: 1.44-5.65) and smoking (current smokers, AOR=10.30: CI: 4.39-24.16) are found to be significantly associated with hypertension. Conclusion This study showed the prevalence of hypertension is high in study population. Increasing age, low level of education, ethnicity and smoking were independent risk factors for hypertension.

Risk factors of adolescent health: mass poll results

Objective. To study the risk factors of noncommunicable disease spread in adolescents based on the mass pole results.Methods. The authors conducted four waves of study within the framework of the monitoring project “Risk factors for human health” in 2014–2017. The study included a multistage stratified territorial random sample of 1,691 patients over 11 years. The research population included 170 adolescents (11–19 years) (10%).Results. An adverse profile of risk factors for noncommunicable diseases was predetermined by: overweight in adolescents (10%), increased blood pressure (18%), unfavorable history of cardiovascular events in close relatives (60–70%), nutritional disorders (80–96%) , low level of physical activity (5%), smoking (20%), and alcohol consumption (26% of respondents). The body weight deficiency (35%) and overweight (10%), along with sufficient consumption of fresh vegetables and fruits in only 7% of cases reflects gross malnutrition of adolescents, which determines their future development. Awareness of adolescents of the main risk factors for noncommunicable diseases remains low (less than 30–40% for different factors). The example of close relatives, friends and stressful situations predetermine the emergence of bad habits (consumption of alcohol and tobacco) in adolescents.Scope of application. Pediatrics, public health, epidemiology.Conclusion. In order to correct adverse risk factors of noncommunicable diseases, it is necessary to attract a wide range of specialists, including intensive family and personal psychological consultations with adolescents. These measures will motivate adolescents to a healthy lifestyle and reduce the burden of noncommunicable diseases in the population of the Russian Federation.

The association of healthy lifestyle behaviors with mental health indicators among adolescents of different family affluence in Belgium

BackgroundHealthy lifestyles may contribute to better mental health, which is particularly important in adolescence, an age at which half of all mental health problems first occur. This association may be even more relevant in adolescents of low family affluence, who show more mental health problems, as well as more unhealthy lifestyles. This study investigated healthy lifestyle behaviors, namely sufficient sleep and physical activity, daily breakfast intake, low levels of alcohol use or smoking, in relation to mental health and symptoms of mental health problems (feelings of depression, anxiety, stress and self-esteem) among adolescents from different family affluence. Furthermore, the moderating role of family affluence was examined in those relations.MethodsAdolescents aged 12-18y were recruited via a random sample of schools in Flanders, Belgium. A total of 1037 adolescents participated (mean age = 15.2, 49.8% female). Independent samples t-tests, Mann Whitney U-tests and χ2-tests determined the differences in healthy lifestyle behaviors and mental health indicators between adolescents of low-medium and high family affluence. Regression analyses assessed the association between healthy lifestyles and mental health outcomes and the moderating role of family affluence.ResultsAll healthy lifestyle behaviors were associated with at least one mental health outcome, with the exception of alcohol consumption. Adolescents from low-medium family affluence had lower levels of physical activity, less often took breakfast, had lower levels of alcohol consumption and reported lower self-esteem than adolescents from high family affluence. The results showed no moderating effect of family affluence for the association between healthy lifestyle and mental health.ConclusionThese findings support the value of integrating healthy lifestyle behaviors in interventions for mental health promotion, for both youth of low-medium and high family affluence.

Expression of Circulating Microparticles for the Diagnosis of Non-small Cell Lung Cancer: Clinicopathological Correlations and Prognostic Value

Increased values of circulating microparticles (MPs) have been reported in solid tumors including non-small cell lung cancer (NSCLC). We therefore investigated the utility of baseline MPs in the clinical setting of patients with NSCLC. Quantification of MPs in the plasma was performed by flowcytometry. Baseline MP values were correlated with clinical patients' characteristics, estimated tumor volume (ETV) and treatment response. Receiver operating characteristics (ROC) curves were plotted to discriminate between patients and controls in order to determine the diagnostic value of circulating MPs in NSCLC. Our prospective study included 134 NSCLC patients (98 at initial diagnosis, ID and 36 at relapse, R) and 30 healthy individuals. The mean of baseline MP numbers was significantly higher in patients presented either at ID or R than in controls (p<0.0001). Basal MP numbers were inversely correlated with ETV values (p=0.04). In addition, the difference in MP levels at diagnosis was significant according to tumor histology (p=0.02) and primary tumor size (p=0.0007). Using ROC analysis, the optimal cutoff value for baseline MPs was 1307 events/µL with a sensitivity and a specificity of 67.3% and 90.0%, respectively. High MPs expression was significantly associated with low-level smoking degree (p=0.001), non-squamous cell types (p=0.017) and decreased tumor size (p=0.003). Our results suggest that high baseline MP values could be an indicator of tumor growth inhibition in NSSLC. Furthermore, high expression of circulating MPs at diagnosis might predict good prognosis in NSCLC patients.

Determinants of Metabolic Health Across Body Mass Index Categories in Central Europe: A Comparison Between Swiss and Czech Populations

Comparisons among countries can help to identify opportunities for the reduction of inequalities in cardiometabolic health. The present cross-sectional analysis and meta-analysis aim to address to what extent obesity traits, socioeconomic, and behavioral factors determine poor metabolic health across body mass index (BMI) categories in two urban population-based samples from Central Europe. Data from the CoLaus (~6,000 participants; Lausanne, Switzerland) and the Kardiovize Brno 2030 (~2,000 participants; Brno, Czech Republic) cohorts. For each cohort, logistic regression analyses were performed to identify the main determinants of poor metabolic health overall and stratified by body mass index (BMI) categories. The results of each cohort were then combined in a meta-analysis. We first observed that waist circumference and body fat mass were associated with metabolic health, especially in non-obese individuals. Moreover, increasing age, being male, having low-medium educational level, abdominal obesity, and high body fat mass were the main determinants of the metabolically unhealthy profile in both cohorts. Meta-analysis stratified by BMI categories confirmed the previous results with slight differences across BMI categories. In fact, increasing age and being male were the main determinants of poor metabolic health independent of obesity status. In contrast, low educational level and current smoking were associated with poor metabolic health only in non-obese individuals. In line, public health strategies against obesity and related comorbidities should aim to improve social conditions and to promote healthy lifestyles before the progression of metabolic disorders.

Nicotine vaping products as a harm reduction tool among smokers: Review of evidence and implications for pharmacy practice.

With the growing popularity and use of nicotine vaping products (NVPs, also known as e-cigarettes) as a way to quit smoking, pharmacy staff are frequently asked by smokers for advice about NVPs. In Australia, there are currently no clear guidelines or policy statements provided by any of the professional organisations for pharmacists on how they should handle customer enquiries about NVPs, or on extemporaneous compounding of prescriptions for nicotine solution for use in NVPs as a smoking cessation aid. This commentary summarises the current evidence surrounding the safety and efficacy of NVPs, the Australian regulatory landscape, and provides a guide for pharmacy staff to use in discussions with customers regarding NVPs. Evidence strongly points to NVPs being considerably less harmful than smoking tobacco cigarettes and that they can be effective for smoking cessation. The maximum benefit from using NVPs as a harm reduction tool, however, will only be realised if smokers completely stop smoking rather than using NVPs as a partial substitute, because even low level smoking still confers substantial health risk. Vaping products containing nicotine are illegal to sell in Australia but users can still legally access nicotine e-liquid through some limited pathways if they hold a valid prescription from a registered medical practitioner. It is important that pharmacy staff keep abreast of the current evidence surrounding these products and provide evidence-based advice to customers.
