Correlation between serum uric acid and creatinine ratio and metabolic syndrome based on physical examination population in Nantong area

To investigate the relationship between serum uric acid to creatinine ratio (SUA/Cr) and metabolic syndrome (MS) and other indexes on physical examination population in Nantong area. Using the method of cross-sectional study, 8 148 physical examiners in the physical examination center of the Affiliated Hospital of Nantong University from January 2017 to April 2020 were used as the research objects, and the clinical data and serum biochemical indicators such as smoking and alcohol addiction, physical examination and so on were collected. According to the standard diagnosis of MS of Diabetes Society of Chinese Medical Association, the patients were grouped according to the quartile of SUA/Cr and the clinical data of each group were compared. Pearson correlation analysis and logistic regression analysis were used to explore the correlation between SUA/Cr and clinical indicators and the relationship between SUA/Cr and the risk of MS. The results showed that UA and SUA/Cr were the lowest in normal metabolism group, followed by abnormal metabolism group and the highest in MS group, The difference between the two groups was statistically significant (H=919.21 and 629.34, P<0.001). According to the SUA/Cr quartile, the population was divided into four groups. After adjusting for gender, age, smoking history and drinking history, SUA/Cr in group Q1 was positively correlated with BMI and TG (r=0.061 and 0.080, P<0.05), but negatively correlated with HDL-C (r=-0.057, P<0.05). Multivariate logistic regression results showed that after adjusting for age, sex, smoking history and drinking history, the risk of MS for BMI, SBP, DBP, FBG, TG, HDL-C and SUA/Cr [OR (95%CI)] were: 1.44 (1.41-1.47), 1.07 (1.06-1.07), 1.10 (1.10-1.11), 1.83 (1.73-1.92), 1.89 (1.79-1.99), 0.08 (0.06-0.10) and 1.54 (1.47-1.62). Compared with SUA/Cr group Q1, the risk of MS in group Q2, Q3 and Q4 increased by 75%, 162% and 346%, respectively. In conclusion, there was an independent positive correlation between SUA/Cr and MS risk in Nantong area.

Determinants of cigarette and e-cigarette use among youth and young adults-PolNicoYouth study results

Abstract Identifying predictors of e-cigarette use initiation is important for preventing young persons from becoming smokers. Because of the addictiveness, harmful effects but on the other hand attractiveness and fashion for e-cigarettes among young people, teen use of tobacco related products is a significant public health concern. This study evaluated the determinants of susceptibility to e-cigarette use to both e-cigarettes use and traditional cigarettes in secondary school students in Poland. This study examined a sample of Polish youths aged 13-19 (n = 19241) attending 192 schools, 12 on average in each voivodship. Logistic regression and multivariable logistic regression models were used to calculate crude and adjusted odds ratios. The profile of susceptibility to e-cigarettes use among never e-cigarette users included: pocket money available per month (more than 150 PLN) (OR = 1.7; p = 0.001), 16-17 years old (OR = 1.9; p = 0.001), parental tobacco smoking and e-cigarette usage (OR = 2.0; p = 0.01 and OR = 1.7; p = 0.001 respectively), maternal secondary education (OR = 1.1; p = 0.04) and living in big cities &amp;gt;500 thou. inhabitants (OR = 1.4; p = 0.04). E-cigarette susceptible persons among ever users were similar to never cigarette users in their opinion that e-cigarettes use are less harmful than conventional smoking (OR = 1.6; p = 0.0012) and living with both parents smoking cigarettes (OR = 1.3; p = 0.02). Additionally, the determinants were: female gender (OR = 1.5; p = 0.009) in the age group less than 15 years of age (OR = 1.3; p = 0.007). The results revealed that such basic predictors as: parental smoking and opinion of lower harmfulness of e-cigarettes use are the most important determinants of smoking susceptibility among never or ever e-cigarette users. The intervention should be focused on educating the young people and their parents on the addictiveness and harmful effects of e-cigarette use and smoking. Key messages

Bilateral upper extremity thrombosis associated with protein C deficiency in a COVID-19 patient; a case report

The coronavirus disease 2019 (COVID-19) or severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has affected different communities all over the world. A wide spectrum of complications has been reported due to COVID-19 infection, among which a hypercoagulability state is one of the most significant. The patient was a 44-year-old obese woman with a history of diabetes, hypothyroidism, cigarette smoking and opium addiction, who had recently been diagnosed with COVID -19 and had undergone cardiac surgery due to right atrial thrombosis. The patient was also affected by bilateral upper extremity thrombosis 20 days after surgery. Protein C deficiency was diagnosed by measuring serum levels and she was discharged from the hospital with apixaban instead of warfarin due to protein c deficiency.

EVALUATION OF SERUM SCUBE-1 LEVELS AND AFFECTING FACTORS IN SMOKERS

Aim: Serum signal peptide-CUB-EGF domain-containing protein-1 (SCUBE-1), an indicator of platelet activation, is a biochemical marker used to evaluate the risk for cardiovascular diseases. This study aimed to evaluate the alteration of plasma levels of SCUBE-1 in smokers compared to healthy controls and determine the affecting factors.&#x0D; Materials and Methods: This prospective study was designed as an experimental, single-centered study with a control group. The study included smokers aged 18-65 years who were admitted to the Smoking Cessation Clinic of a tertiary hospital and a control group consisting of healthy volunteers admitted to the Family Medicine Outpatient Clinic and had never smoked. Sociodemographic data of all participants and smoking histories and addiction levels of smokers were questioned. Exhaled carbon monoxide (CO) levels were measured. Plasma SCUBE-1 levels were studied and compared from samples obtained from venous blood. &#x0D; Results: A total of 82 individuals, consisting of the "smoker" patient group (n=44) and the "non-smoker" control group (n=38), were included in the study. While the mean SCUBE-1 value was 1.28±0.70 ng/ml in smokers, it was 1.54±1.09 ng/ml in non-smokers. There was no statistical difference between smokers and non-smokers in terms of SCUBE-1 (p=0.500). There was no statistically significant correlation between SCUBE-1 levels and exhaled CO level, smoking characteristics and addiction levels in smokers. &#x0D; Conclusion: Our study showed that the plasma SCUBE-1 value in smokers did not increase at statistically significant levels compared to the control group. Therefore, it was concluded that it would not be useful in evaluating the risk of cardiovascular diseases and the susceptibility to thrombosis.

Increased Risk of Generalized Anxiety Disorder According to Frequent Sedentary Times Based on the 16th Korea Youth Risk Behavior Web-Based Survey.

This study aimed to identify the association between sedentary behavior and anxiety disorders in 53,510 Korean adolescents. It analyzed data from the 16th (2020) Korea Youth Risk Behavior Web-based Survey (KYRBS). The dependent variable was the generalized anxiety disorder-7 (GAD-7). The GAD-7 scores were divided into normal, mild, moderate, and severe levels. The independent variables were sedentary time for learning, other sedentary times, total sedentary time, and regular physical activity. The confounding variables were sex, grade, stress, depression, substance abuse, suicidal thoughts, violent victimization, drinking, smoking, sleep satisfaction, and smartphone addiction. A chi-squared test, one-way analysis of variance, and logistic regression analysis were used for analysis. After adjusting for all confounding variables, the risk of severe level in GAD-7 increased by 1.045 times each time the sedentary time for learning based on increased by one hour. In other sedentary time and total sedentary time, the risk of severe level in GAD-7 increased by 1.025 times and 1.045 times per hour, respectively. However, in regular physical activity, after adjusting for the confounding variables, there was no significant association with the GAD-7 levels. Therefore, to prevent generalized anxiety disorders in Korean adolescents, it is necessary to reduce the overall sedentary times including sedentary time for learning.

Impact of the COVID-19 pandemic on non-COVID-19 hospital mortality in patients with schizophrenia: a nationwide population-based cohort study

It remains unknown to what degree resource prioritization toward SARS-CoV-2 (2019-nCoV) coronavirus (COVID-19) cases had disrupted usual acute care for non-COVID-19 patients, especially in the most vulnerable populations such as patients with schizophrenia. The objective was to establish whether the impact of the COVID-19 pandemic on non-COVID-19 hospital mortality and access to hospital care differed between patients with schizophrenia versus without severe mental disorder. We conducted a nationwide population-based cohort study of all non-COVID-19 acute hospitalizations in the pre-COVID-19 (March 1, 2019 through December 31, 2019) and COVID-19 (March 1, 2020 through December 31, 2020) periods in France. We divided the population into patients with schizophrenia and age/sex-matched patients without severe mental disorder (1:10). Using a difference-in-differences approach, we performed multivariate patient-level logistic regression models (adjusted odds ratio, aOR) with adjustment for complementary health insurance, smoking, alcohol and substance addiction, Charlson comorbidity score, origin of the patient, category of care, intensive care unit (ICU) care, major diagnosis groups and hospital characteristics. A total of 198,186 patients with schizophrenia were matched with 1,981,860 controls. The 90-day hospital mortality in patients with schizophrenia increased significantly more versus controls (aOR = 1.18; p < 0.001). This increased mortality was found for poisoning and injury (aOR = 1.26; p = 0.033), respiratory diseases (aOR = 1.19; p = 0.008) and for both surgery (aOR = 1.26; p = 0.008) and medical care settings (aOR = 1.16; p = 0.001). Significant changes in the case mix were noted with reduced admission in the ICU and for several somatic diseases including cancer, circulatory and digestive diseases and stroke for patients with schizophrenia compared to controls. These results suggest a greater deterioration in access to, effectiveness and safety of non-COVID-19 acute care in patients with schizophrenia compared to patients without severe mental disorders. These findings question hospitals’ resilience pertaining to patient safety and underline the importance of developing specific strategies for vulnerable patients in anticipation of future public health emergencies.

Prevalence, knowledge and attitude toward electronic cigarette use among male health colleges students in Saudi Arabia-A cross-sectional study.

BackgroundHealth care professionals have an important role in increasing awareness about smoking harms and serving as role models. This study aims to assess knowledge, attitude and perception toward electronic cigarettes (ECs) as well as prevalence of ECs use among male health colleges students.MethodThis is a cross-sectional survey-based study conducted among students in the male campus of five different health colleges over a 4-month period from February 2020 to May 2020. Descriptive analysis was used to assess the knowledge, perception and attitude, and inferential testing was used to evaluate the association of different participant's variables and knowledge toward ECs usage using SPSS.ResultsA total of 333 students were included in the analysis. Most of students (n = 205; 61.6%) had never used ECs, while 22.8 and 15.6% used them for recreational and smoking cessation purposes, respectively. Focusing on ECs users from each college individually, medical students had the highest prevalence followed by dental, pharmacy and nursing students (47.4, 40.7, 34.5, and 32%, respectively). Many students had misconceptions and a low level of knowledge about ECs, such as recognizing them as smoking-cessation tools and not knowing whether toxic and carcinogenic components levels in ECs are similar to conventional cigarettes, respectively. Medical students had significantly higher knowledge compared to dental students [3 (2) vs. 2 (1); p = 0.033]. Moreover, smokers were less knowledgeable than non-smokers [2.5 (1) vs. 2.1 (1), p = 0.027]. At least 62.8% of students perceived using ECs as a fashionable alternative smoking method and 59.2% believed that they may become a gateway for smoking addiction. Only 120 (36.0%) health colleges students were confidently able to advise smokers regarding ECs.ConclusionOur study highlights an increased trend of ECs use accompanied with insufficient knowledge and several misconceptions about ECs among health colleges students. This was associated with a negative influence on their attitude toward ECs use, which would potentially lead to negative consequences on public health.

Effect of Fasting on Smoking Addiction: A Multicentered Primary Care Research.

Smoking is a serious public health challenge across the world. Fasting in Ramadan requires people to stay away from smoking as well as activities such as eating, drinking, and sexual intercourse. We examined the effect of fasting on cigarette smoking and nicotine addiction during the Ramadan. This study was designed as a descriptive cross-sectional survey. A questionnaire was prepared to determine sociodemographic data and smoking habits of a sample population. The questionnaire was delivered through face-to-face interviews at several family medicine clinics in Turkey, with smokers who fast in Ramadan. There were 354 persons, of which 278 were male (78.5%), 76 were female (21.5%), and the mean age was 32.92 ± 11.84 years. A significant decrease in cigarette consumption during the Ramadan was reported by 285 (80.5%) smokers ( p < .001). The number of smokers who had difficulty resisting the urge to smoke was less in Ramadan than non-Ramadan periods ( p < .001). Religious sentiments were reported as the most important reason for coping with nicotine abstinence (53.7%). Significantly in 14.7% of the cases, participants stopped smoking during the whole period of Ramadan. Religious beliefs and willpower were found to be effective in helping people reduce or temporary stop smoking. Fasting may play a significant role in changing smoking behavior. Smoking cessation along with counseling supported by the state, health authorities, and clergy can be useful in the fight against smoking in Ramadan.

Evaluation of knowledge and awareness levels of drugs used in smoking cessation treatment

Introduction: It is among the modifiable risk factors for cardiovascular diseases and stroke. In the follow-ups after quitting this habit, it has been shown that there is a decrease in the mortality rate related to the cardiovascular system and an increase in the quality of life of the patients. In this study, it was aimed to investigate the awareness of the drugs used in smoking cessation on patients and healthy individuals. Methods: Our study was planned as cross-sectional. Patients who applied with any complaints and 198 volunteers from healthcare professionals working in the hospital were included. With the questions in the questionnaire, it was aimed to learn the awareness levels about the drugs used in smoking cessation. Results: In our study, it was determined that women and other professionals did not have statistically significant information in the question in which the effects of these drugs on pulse and blood pressure levels were evaluated. The statement that individuals in other occupational groups did not know about the effect of bupropion treatment on this system was found to be statistically significantly higher (p<0.01). Conclusion: Drug treatments have an important place in getting rid of smoking addiction, which is a very important public health problem, and it is known that these treatments are safe even in those with a history of cardiovascular disease. Knowing these treatments and being able to prescribe these drugs safely if their patients are stable will have a very important place in the fight against smoking.

Smoking and smoking addiction in future physicians during the COVID-19 pandemic; an example of a medical school in Turkey

ABSTRACT Objectives The aim of this study was to assess the prevalence of cigarette and other tobacco use of medical students, and to determine the levels of smoking addiction and to evaluate the effect of the pandemic. Methods The cross-sectional study was carried out in January 2022. Results A total of 487 students, the lifetime tobacco use and current tobacco use prevalence was 62% and 40.2%. Current (past 1 month) electronic cigarette, cigar or pipe, hookah, cigarette prevalence was 2.7%, 6.8%, 11.1%, 39.4% respectively and daily cigarette 21.1%. It was found that 19.4% of students had moderate to high level of addiction. Seventy percent of students with moderate to high addiction and 41% of students with low addiction reported increased smoking. Most of the daily smokers stated that their desire to smoke did not decrease due to COVID-19, and 46.6% increased smoking. Forty percent of those with moderate to high levels of addiction and 6% of those with low addiction thought that the disease would be severe if they were infected with COVID-19. Conclusions It was found that students with moderate to high level of addiction increased smoking more and their attempts to quit smoking were less. Students should be provided with support to quit smoking.

Economic &amp; Time-varying Consequences of Smoking Addiction among Nurses on Work Performance from the Aspect of Nursing Management

Objective: The aim of our study was to determine the impact of smoking addiction on nurses on their work performance and economic and time-varying consequences. Design: Cross-sectional study. Participants: The sample consisted of 381 nurses who worked in hospitals in Slovakia and the Czech Republic. Methods: The data were collected through non-standardized questionnaires in the period July 2020-March 2021. The questionnaires were prepared in 3 versions according to the target sample for which they were intended.Results: The financial loss caused by smoking during the working hours costs employer EUR 862.50 per smoking nurse per year and the time lost due to smoking takes up to 15 working days every year. Conclusion: Managers are not interested in time lost due to smoking during working hours. Management's lack of interest or their indifferent attitude is alarming. Nurse managers should begin to perceive nurses' smoking as a limiting factor in nurses' work performance, given the shorter time devoted to the provision of nursing care.

Evaluation of the Effectiveness of Supportive Group Therapy on Fear of Delivery in Pregnant Women, 2021

Background and Objective: Fear of childbirth is one of the major problems in delivery and the postpartum period. In most women, fear of childbirth is associated with increased pain, prolonged labor and unpleasant labor experience, and increased rate of elective cesarean section Materials and Methods: This interventional study was conducted on 90 pregnant women referred to health centers in Kordkuy, Iran. They were randomly assigned to two groups: intervention and control. The inclusion criteria entailed a wish for cesarean delivery or being doubtful about the mode of delivery, primigravida, singleton pregnancy, the age range of 18-35 years, reading and writing literacy, gestational age of 22-30 weeks at the beginning of the study, and a healthy fetus based on ultrasound examinations in the first trimester. The exclusion criteria were as follows: clear and identifiable obstacles to natural childbirth at the time of sampling, mental and neurological disorders, smoking, drug, and alcohol addiction, repeated abortions, and a history of infertility. The data collection tools included the Wijma Delivery Expectancy/Experience Questionnaire (version A) and the demographic information form. The intervention in the experimental group was performed in five one-hour sessions, while the control group received routine pregnancy care. The data were analyzed in SPSS software using independent chi-square and independent t-tests. Results: Before the intervention, demographic variables, such as age, occupation, and education, were homogeneous between the intervention and control groups. At the end of the support group therapy sessions, the mean fear of childbirth score in the intervention group was 69.22, which was significantly lower than that in the control group (84.58) (P&lt;0.001). Conclusion: Midwifery counseling in the form of supportive group therapy is effective in reducing the fear of childbirth. Considering that some pregnant women were compelled to undergo a cesarean section due to the opposition of their husbands, it is necessary to conduct studies on the effects of support group therapy on the fear of childbirth in groups consisting of pregnant women, as well as their spouses and families.

Impact of a Coronavirus Pandemic on Smoking Behavior in University Students: An Online Survey in Türkiye.

Coronavirus Disease-2019 (COVID-19) pandemic has a massive impact on human health, causing sudden lifestyle changes. As it affects health, determining the lifestyles of university students related to smoking has gained importance. This study provides evidence of change in smoking behavior among university students in Türkiye during the ongoing COVID-19 pandemic. This cross-sectional survey study was conducted via an electronic questionnaire approximately 2020-2021 among university students in Türkiye. The study comprised a structured questionnaire that inquired about demographic information; and the Fagerström Test for Nicotine Dependence. The questionnaire was distributed randomly to university students; it required 6 min to complete. A total of 749 respondents were included in the study, aged between 19 and 35 years (54.8% females). Of 749 participants, 571 health science students (medicine, pharmacy, dentistry, etc.) completed the survey. The pre-pandemic and COVID-19 pandemic mean nicotine dependence scores were 3.03 and 2.97, respectively. A difference was seen pre-pandemic (p= 0.002) and during pandemic (p= 0.005) for those studying in health and other departments. Students who had middle socio-economical status had significantly higher nicotine dependence scores pre- COVID-19, compared to during the pandemic (p= 0.027). Compared to pre and during the pandemic, the mean score of dependence was significantly lower in students, whose parents were non-smokers during the pandemic. In this study, we have provided the first data on the Turkish university student's nicotine dependence changes during the COVID-19 lockdown. The nicotine dependence level may change based on various factors including behavioral changes. Crucial times such as pandemics can affect individuals, thus, smoking addiction can increase. Behavioral support for quitting smoking such as digital platforms, internet, and television programs should also assist to support smokers quitting successfully during this supreme time.

Association of Polymorphism CHRNA5 and CHRNA3 Gene in People Addicted to Nicotine.

Smoking is a chronic and relapsing addictive trait that harms public health. Among the many identified genetic variants of nicotine dependence, the variants in the CHRNA5/A3/B4 gene cluster on chromosome 15 that encode the α5, α3, and β4 subunits have recently received a lot of attention. Importantly, variants in this gene cluster have been associated with nicotine addiction. Among the many significant variants in this cluster, the polymorphism SNP rs16969968 seems to be the most interesting factor in nicotine addiction. This polymorphism causes an amino acid change from aspartate to asparagine at position 398 of the α5 nicotinic receptor protein sequence. Our study aimed to analyze three polymorphic variants: the rs16969968 located in the CHRNA5 gene, the rs578776 and rs1051730 located in the CHRNA3 gene in nicotine-addicted subjects, and in controls. Our study encompasses an association analysis of genotypes and haplotypes. A group of 401 volunteers was recruited for the study and divided into two groups: the study group consisted of addicted smokers and a control group of 200 unrelated non-smokers who were not dependent on any substance and healthy. A statistically significant difference was observed in the frequency of genotypes of the rs1051730 polymorphism of the CHRNA3 gene (χ2 = 6.704 p = 0.035). The T/T genotype was statistically significantly more frequent in the group of nicotine-dependent subjects. The haplotypes rs16969968, rs578776, and rs1051730 were distinguished, of which the G-T-T and G-C-T haplotypes were present only in the study group. With differences in frequencies, statistical significance was noted—for the G-T-T haplotype p = 0.01284 and the G-C-T haplotype p = 0.00775. The research stated that novel haplotypes G-T-T and G-C-T, though with very low-frequency variants in CHRNA3, were associated with nicotine addiction.

Parental divorce and smoking dependence in Lebanese adolescents: the mediating effect of mental health problems

BackgroundLebanon has the highest prevalence estimates among Middle Eastern countries and Arab women regarding cigarette smoking, with 43% of men and 28% of women involved in such trends. Marital disruption is a tremendous source of irritability and discomfort that may hinder a child's healthy development, creating perturbing distress and increasing disobedience that may exacerbate smoking addiction. Additionally, Lebanese adolescents are inflicted by high emotional and economic instability levels, rendering increased susceptibility to distress and propensity to engage in addictive behavior. This study aims to investigate the association between parental divorce and smoking dependence among Lebanese adolescents, along with exploring the potential mediating effect of mental health disorders of such correlation.MethodsA total of 1810 adolescents (14 and 17 years) enrolled in this cross-sectional survey-based study (January-May 2019). Linear regressions were conducted to check for variables associated with cigarette and waterpipe dependence. PROCESS v3.4 model 4 was used to check for the mediating effect of mental health disorders between parental divorce and smoking dependence.ResultsHigher suicidal ideation and having divorced parents vs living together were significantly associated with more cigarette and waterpipe dependence. Higher anxiety was significantly associated with more waterpipe dependence. Insomnia and suicidal ideation played a mediating role between parental divorce and cigarette/waterpipe dependence.ConclusionOur results consolidate the results found in the literature about the association between parental divorce and smoking addiction and the mediating effect of mental health issues. We do not know still in the divorce itself or factors related to it are incriminated in the higher amount of smoking in those adolescents. Those results should be used to inspire parents about the deleterious effect of divorce on their children to lower their risk of smoking addiction. Further longitudinal studies are needed to better understand the complexity of such associations and to see whether the divorce experience by itself or the factors that accompany it are involved in the increased smoking addiction among adolescents.

Study on the effects of combined tea drinking and mental activity after dinner on smokers in China.

INTRODUCTIONCigarette and tobacco use is a leading cause of chronic obstructive pulmonary disease, lung cancer, and other malignant tumors. In China, people prefer to engage in mental activities (gambling, overtime work, playing video games, or other mental activities) on the weekends or during spare time, especially in the evening before they prepare for bed. In China, smokers frequently consume tea while smoking. The relationship between smokers who consume tea, engage in mental activities after dinner, or both (drinking tea and engaging in cognitive activities after dinner together), and daily cigarette smoking or nicotine addiction must be clarified.METHODSA total of 438 smokers were included in the study. Age, gender, body mass index (BMI), smoking habits, Fagerström test for nicotine dependence scores, and behaviors, were recorded. The study excluded smokers with a Fagerström score <1 or with a mental disorder diagnosis. The smokers were divided into four groups based on their behaviors: those who did not drink tea, did not engage in mental activities after dinner, those who drank tea only, those who engaged in mental activities only, and those who engaged in both.RESULTSOnly drinking tea or doing mental activities after dinner cannot increase cigarettes per day (22.20 ± 10.143 vs 23.49 ± 11.966, p=0.362; 22.20 ± 10.143 vs 22.66 ± 1.192, p=0.750) or FTND scores [6.0 (4.0; 7.0) vs 6.0 (4.0; 7.75), p=0.941; 6.0 (4.0; 7.0) vs 6.0 (4.25; 7.75), p=0.980]. People who drink tea and engage in mental activities after dinner smoke more (22.20 ± 10.143 vs 30.75 ± 17.264, p<0.0001) and have higher nicotine dependence levels [6.0 (4.0; 7.0) vs 7.0 (5.0; 8.0), p=0.015].CONCLUSIONSThe consumption of tea or a mental activity after dinner is not associated with daily smoking or nicotine dependence. There is an association between the combined behaviors (tea drinking and mental activity after dinner) and the daily consumption of cigarettes, and the degree of nicotine dependence.

The 1964 US Surgeon General's report on smoking and health.

The 1964 report of the US Surgeon General on smoking and health made an authoritative case that tobacco smoking was a cause of premature deaths from lung cancer and chronic bronchitis. It justified the practice of drawing causal inferences from epidemiological studies, specified influential criteria for doing so, and made use of an early form of meta-analysis.
