Hong Q, Liao Y, Zhang N. Implicit Theories of Smoking and Intention to Quit: A Serial Mediation Model. Nicotine Tob Res 2024; 26:621-628. [PMID: 37878750 DOI: 10.1093/ntr/ntad213] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 09/06/2023] [Accepted: 10/16/2023] [Indexed: 10/27/2023]
Abstract
INTRODUCTION There is growing evidence that implicit theories of smoking (ITS)-whether smokers perceive smoking behavior as malleable or fixed-are significant predictors of quitting intentions. AIMS AND METHODS This cross-sectional study aims to investigate the underlying mechanisms of implicit theories on smoking in predicting smokers' intentions to quit. We conducted multiple linear regression with quitting intentions as the dependent variable, ITS as the independent variable, and sociodemographic variables, quitting attempts in the past year, and receiving quitting advice in the past 12 months as the covariates. The mediating role of consideration of future consequences (CFC) and self-efficacy in the relationship between implicit theories of smoking and quitting intentions was evaluated by mediation analyses. RESULTS A total of 510 smokers were included in the final analyses. Smokers holding a higher incremental theory of smoking reported a higher likelihood of considering future consequences (β = 0.289, p < .001) and a weaker possibility of considering immediate results (β = -0.317, p < .001), which, in turn, enhanced their quitting self-efficacy and then led to stronger intentions to quit smoking (β = 0.261, p < .001). CONCLUSIONS The current study enriched our understanding of the underlying mechanisms that connect smokers' ITS and their likelihood of smoking cessation such that higher incremental theories of smoking predict stronger intention to quit smoking, and the effect was serially mediated by smokers' likelihood of considering future consequences of their behavior and their perceived self-efficacy for smoking cessation. IMPLICATIONS This study indicated the mediating role of CFC and self-efficacy for smoking cessation on the relationship between the ITS and quitting intentions. These two psychological factors and the pathways may be important points for understanding the model of implicit theories for smoking and improving the effectiveness of implicit theories-based intervention on smoking cessation.

Khan AU, Shah A, Majeed MT, Ahmad S. Predictors of quitting smoking behavior: evidence from Pakistan. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2024:10.1007/s11356-024-32920-y. [PMID: 38619768 DOI: 10.1007/s11356-024-32920-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/28/2022] [Accepted: 03/11/2024] [Indexed: 04/16/2024]
Abstract
This study attempts to identify factors that significantly encourage the cessation of smoking in the context of Pakistan. The study distributes a modified questionnaire among 421 respondents (current as well as former smokers) in the capital city of Pakistan, Islamabad. The binary regression method was employed to data for analyzing predictors of making quit attempts and successful smoking cessation. The result indicates that respondents having strong intentions to quit, high socioeconomic status, low nicotine dependency, and past quit attempts, and those having no-smoking friends, are more likely to quit cigarette smoking successfully. On the other hand, factors like social pressure to quit smoking, religious information against smoking, intention to quit smoking, and public regulation on smoking are more likely to encourage smokers to make quit attempts. The study calls for community and school-wide smoking cessation campaigns involving officials, peers and parents, religious leaders, and other influential individuals to inform people about the dangers of smoking. In addition, religious leaders should be encouraged to issue rulings against smoking especially during "Friday Prayer." Furthermore, the government should pronounce more strict and comprehensive regulations on smoking by properly monitoring its implementation to encourage cessation of cigarette smoking.

Xu M, Li F, Xu X, Hu N, Miao J, Zhao Y, Ji S, Wang Y, Wang L. Proteomic analysis reveals that cigarette smoke exposure diminishes ovarian reserve in mice by disrupting the CREB1-mediated ovarian granulosa cell proliferation-apoptosis balance. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2024; 271:115989. [PMID: 38242047 DOI: 10.1016/j.ecoenv.2024.115989] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Revised: 12/31/2023] [Accepted: 01/13/2024] [Indexed: 01/21/2024]
Abstract
Exposure to cigarette smoke (CS) adversely affects ovarian health and it is currently unknown how CS exposure causes ovarian injury. This study compared the differences in proteomics between CS exposure and healthy control groups using liquid chromatography-tandem mass spectrometry quantitative proteomics to further understand the molecular mechanism of ovarian cell injury in mice exposed to CS. Furthermore, western blotting and qPCR were carried out to validate the proteomic analysis outcomes. CREB1 was selected from the differentially expressed proteins, and then the down-regulation of CREB1 and phosphorylated CREB1(Ser133) expressions were confirmed in mice ovarian tissue and human ovarian granulosa cells (KGN cells) after CS exposure. In addition, the expressions of apoptosis-related proteins BCL-2 and BCL-XL were downregulated, and BAX expression was up-regulated. Moreover, the results of cellular immunofluorescence, flow cytometry, and transmission electron microscopy (TEM) showed that cigarette smoke extract (CSE) efficiently stimulated the production of reactive oxygen species, apoptosis, G1 phase arrest, mitochondrial membrane potential decreases, and ultrastructural changes in KGN cells. KG-501 (CREB inhibitor) aggravated CSE-induced mitochondrial dysfunction and apoptosis-proliferation imbalance in KGN cells mediated by down-regulated CREB1/BCL-2 axis. In addition, CREB1 over-expression partially restores mitochondrial dysfunction and apoptosis-proliferation imbalance of KGN cells induced by CSE. The results suggested that CSE diminished ovarian reserve in mice by disrupting the CREB1-mediated ovarian granulosa cell (GCs) proliferation-apoptosis balance and provided possible therapeutic targets for the clinical intervention of premature ovarian failure (POI) caused by CS exposure.

Trends of ischemic heart disease mortality attributable to smoking in the five countries with the highest number of smokers during 1990-2019: an age-period-cohort analysis. Arch Med Sci 2024; 20:43-53. [PMID: 38414476 PMCID: PMC10895949 DOI: 10.5114/aoms/182886] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Accepted: 01/20/2024] [Indexed: 02/29/2024] Open
Abstract
Introduction Smoking increases the risk of various cardiovascular diseases, including ischemic heart disease (IHD). This study aimed to assess the impact of age, period, and cohort on long-term trends in IHD mortality in China, India, Indonesia, the United States, and Russia, the five countries with the highest number of smokers, from 1990 to 2019. Material and methods The data were obtained from the Global Burden of Disease (GBD) Study 2019, and the age-standardized mortality rate (ASMR) was calculated. Joinpoint regression analysis was used to assess the magnitude and direction of trends in smoking-attributable mortality from IHD. Age-period-cohort (APC) studies were used to estimate net drift (estimated annual percentage change (EAPC)s), local drift (age-specific EAPCs), and independent trends in age, period, and cohort effects. Results The analysis revealed a significant downward trend in ASMRs attributable to IHD as a result of smoking in the United States, India, and Russia. Indonesia and China showed an upward trend. Age effects were increasing for both country and sex, with China showing the most significant increase in the older age group; period effects were decreasing in all countries except Indonesia, and cohort effects were increasing only in Indonesia and China. Conclusions From 1990 to 2019, mortality from IHD caused by smoking showed a downward trend in these five countries. However, the pattern of increased mortality from IHD in women caused by smoking warrants further study.

Evidence-based core information for health communication of tobacco control: The effect of smoking on risks of female disease. Front Public Health 2022; 10:986430. [PMID: 36330111 PMCID: PMC9623329 DOI: 10.3389/fpubh.2022.986430] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Accepted: 09/15/2022] [Indexed: 01/26/2023] Open
Abstract
Objective Cigarettes have become the the biggest killer of contemporary female's health and beauty. What kind of health information is suitable for the general public is an important issue to be discussed globally. The purpose of this study is to generate systematic, rigorous, public-demand-oriented and appropriate core information relevant to tobacco control based on the best available evidence, combined with audience preferences and pre-dissemination content review from multidisciplinary expertise in order to improve the effectiveness of health communication of tobacco control. Methods Relevant systematic reviews meta-analysis that reported smoking on risks of female disease were identified by searching PubMed, Embase, the Cochrane Library, Web of Science, Clinical Trials.gov, and the International Clinical Trial Registry Platform. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) process was applied to assess the evidence in order to make rigorous core information. The audience prevalence survey was conducted to ensure that core information was targeted and tailored. Finally, the expert assessment was used for a pre-dissemination content review and to evaluate whether the core information was appropriate or not. Results The final core information consisted of eight parts concerning the effects of smoking and female cardiovascular disease, diabetes, rheumatoid arthritis, respiratory disease, digestive system disease, mental disease, non-pregnant female reproductive system disease, as well as pregnant women and their fetuses. A total of 35 items of core information suitable for dissemination was included and the quality of evidence, the degree of public demand and the outcome of pre-dissemination content review were reported. Conclusion The core information related to female cardiovascular system diseases, as well as liver cancer and upper gastrointestinal cancer is the preferred content for health communication of tobacco control. The quality of evidence for core information related to pregnant women and their infants, as well as diseases of reproductive system, respiratory system, and diabetes needs to be improved to meet high public demand. The core information related to mental disease is more suitable for dissemination to patients with mental illness than to the general public. Besides, dissemination of core information should be individualized. Evidence-based Core Information for Health Communication of Tobacco Control would be helpful to provide evidence support for health communication related to tobacco control and enhance public health literacy for international communities that have high smoking prevalence and related disease burden.
