A model to explain smokeless tobacco consumption in adults: A grounded theory study.

Introduction: Smokeless tobacco use remains a significant public health concern, necessitating the acquisition of comprehensive and extensive data to effectively address and control its consumption. Understanding the underlying patterns of consumption is crucial for this purpose. Objective: This study aimed to develop a model that explains smokeless tobacco consumption among adults in the southeastern province of Iran, specifically in the city of Chabahar. Methods: A qualitative study was conducted using a grounded theory approach with inductive processes. The participants consisted of 30 adults aged 18-64 years from Chabahar City in southeastern Iran. Purposive sampling was used to select participants, and data collection continued until theoretical saturation was achieved. Data analysis followed Strauss and Corbin's perspective, involving four stages: Analyzing Data for Concepts, Analyzing Data for Context, Bringing Process into the Analysis, and Integrating Categories. Results: The analysis of data yielded three main categories: "starting to use," "continued use," and "cessation attempts," each with their respective subcategories. Additionally, two main categories related to the consequences of smokeless tobacco consumption were identified: "addiction and efforts to overcome addiction," also with their respective subcategories. Conclusion: The Dependency Cycle Model in Consumption provides a comprehensive understanding of the contextual factors, processes, and consequences associated with smokeless tobacco consumption. This model serves as a valuable tool for researchers aiming to develop effective interventions in the field of smokeless tobacco consumption.

The role of intrapersonal and interpersonal factors in waterpipe cessation: a case-control study.

BACKGROUND: The prevalence of waterpipe smoking among women in southern Iran is significantly higher than women in other regions of Iran. We aimed to explore the effect of several demographic factors, knowledge, attitude, self-efficacy and social norms on a successful cessation of waterpipe smoking in the marginalized women of Bandar Abbas city, in the south of Iran. METHODS: This case-control study was conducted in 2022 among 731 women (246 subjects who successfully quit waterpipe smoking in the case group and 485 who smoked waterpipe in the control group). A cluster sampling method was used to collect the required data through face-to-face interviews and a researcher-made questionnaire. The questionnaire consisted of demographic information, behavioral information about waterpipe smoking and knowledge, attitude, self-efficacy and social norms. The data were analyzed in STATA 14 using univariate and multivariate regression analyses. RESULTS: The mean and standard deviation of age was 39.24 ± 11.93 and 37.18 ± 13.57 in the control and case groups, respectively. With an increase of one score in social norm (OR: 1.046), the odds of cessation were increased for 4%. With an increase of one score in self-efficacy (OR: 1.152), the odds of cessation were increased for 15%. With an increase of one score in knowledge (OR: 1.064), the odds of cessation were increased for 6%. With an increase of one score in attitude (OR: 1.215) the odds of cessation were increased for 21%. CONCLUSION: The present findings revealed personal and interpersonal influential factors in successful waterpipe cessation. Women's knowledge can be increased and their attitude can be changed. Important people in women's lives can be influenced to, consequently, affect women positively and improve their self-esteem.

The effectiveness of educational program based on health belief model on promotion of puberty health concepts among teen girls: a cross-sectional study in north of Iran.

BACKGROUND: Puberty is a sensitive critical stage of human life. As numerous healthy habits and behaviors are created during adolescence, correct health education during puberty is essential to maintain and improve an individual's physical, emotional, and mental health. The present study aimed to determine the impact of educational intervention based on the predictors of the Health Belief Model (HBM) on female nine-grade students' health behaviors in Rasht, Iran. METHODS: The present randomized controlled trial study examined 110 female nine-grade students. Multi-stage sampling was performed, and the students were randomly divided into two groups of 55 as intervention and control. The data collection tool included a valid and reliable questionnaire with four sections, namely demographic variables, knowledge, HBM constructs, and health behaviors during puberty. The educational program comprised four 45-60-min sessions per group (4 groups of 13) based on HBM. The data were collected two times, before and 1 month after the educational intervention, and were analyzed using the independent t-test, paired t-test, chi-square test, and SPSS 23. RESULTS: The mean age of menarche was 12.26 ± 1.133 in the intervention group and 12.12 ± 1.263 in the control group. The family was a source of information for students and the main cue to action before the intervention. Before the educational intervention, there was no significant difference between the experimental and control groups in terms of knowledge, HBM constructs, and puberty health behaviors; however, the variables increased significantly in the intervention group after educational intervention (P<0.001). CONCLUSIONS: Given the effectiveness of the HBM in improving the health behavior of adolescent girls, it is recommended that health policymakers should plan and implement educational interventions in this field.

A Bayesian approach to correct the under-count of cancer registry statistics before population-based cancer registry program.

Aim: This study aims to correct undercounts in cancer data before initiating a population-based cancer registry program, employing an innovative Bayesian methodology. Background: Underestimation is a widespread issue in cancer registries within developing countries. Methods: This secondary study utilized cancer registry data. We employed the Bayesian approach to correct undercounting in cancer data from 2005 to 2010, using the ratio of pathology to population-based data in the Golestan province as the initial value. Results: The results of this study showed that the lowest percentage of undercounting belonged to Khorasan Razavi province with an average of 21% and the highest percentage belonged to Sistan and Baluchestan province with an average of 38%.The average age-standardized incidence rate (ASR) for all provinces of the country except Golestan province was equal to 105.72 (Confidence interval (CI) 95% 105.35-106.09) per 100,000 and after Bayesian correction was 137.17 (CI 95% 136.74-137.60) per 100,000. In 2010 the amount of ASR before Bayesian correction was 100.28 (CI 95% 124.39-127.09) per 100,000 for women and 136.49 (CI 95% 171.20-174.38) per 100,000 for men. Also, after implementing the Bayesian correction, ASR increased to 125.74 per 100,000 for women and 172.79 per 100,000 for men. Conclusion: The study demonstrates the effectiveness of the Bayesian approach in correcting undercounting in cancer registries. By utilizing the Bayesian method, the average ASR after Bayesian correction with a 29.74 percent change was 137.17 per 100,000. These corrected estimates provide more accurate information on cancer burden and can contribute to improved public health programs and policy evaluation. Furthermore, this research emphasizes the suitability of the Bayesian method for addressing underestimation in cancer registries. It also underscores its pivotal role in shaping the trajectory of future investigations in this field.

BACKGROUND: Smokeless tobacco use is a public health problem. This study explored students' beliefs about smokeless tobacco use in Chabahar, Iran. MATERIALS AND METHODS: The qualitative study was conducted using three Focused Group Discussions among 24 students aged 12-14 years in Chabahar City. Focus Group Guide Morgan was used. Qualitative Content Analysis was used to explore and extract codes and themes. The data analysis process was carried out in accordance with the stages of proposed by Graneheim and Lundman. Guba and Lincoln criteria were used for evaluating research transferability. RESULTS: Two main themes emerged from the analysis including; beliefs of being useful and harmful. Each of these themes is divided into subthemes with useful or harmful physical and psychological beliefs. Four subthemes included: beliefs of being useful physically, beliefs of being useful psychologically, harmful beliefs physically, and harmful beliefs psychologically. CONCLUSIONS: One of the more significant findings to emerge from this study is that many students mentioned the benefits of using smokeless tobacco to reduce toothache, relieve headaches, and bad breath. This information can be used to develop targeted interventions aimed at reducing smokeless tobacco consumption. However, more research on this topic needs to be undertaken before the association between kinds of beliefs and smokeless tobacco consumption is more clearly understood.

The Reasons for Using Smokeless Tobacco: A Review.

BACKGROUND: Smokeless tobacco use is a public health problem in some parts of the world. The major objective of this study was to investigate the reasons and factors of consumption. METHODS: A content analysis was conducted on articles for the past thirty years (1989-2019). We reviewed and selected 400 abstracts of original articles from PubMed databases by the search strategy, and reviewed one by one. Among these, 45 abstracts were selected, in which the patterns of use, the reasons for using, and the determinants and predictors were described. Eleven papers were selected based on the results and related to the research objectives. The results of these articles were evaluated precisely word by word and phrase by phrase with content analysis method and inductive approach. RESULTS: The reasons for the use of smokeless tobacco fell in two main themes: socio-cultural structure; and, beliefs, each contained Sub-themes such as "culture and living conditions", "laws", "family and peer relationships", "beliefs related to psychological" and "beliefs related to physical influences", "beliefs", "The role of harm perceptions ". CONCLUSION: There was a difference between beliefs, cultures and social conditions among the people about using of smokeless tobacco and the association of these factors is investigated in future studies. We also suggest for the prevention and control of smokeless tobacco use, cultural norms and beliefs will need to address adequately.

Smokeless Tobacco Use in Iran: A Systematic Review.

BACKGROUND: Smokeless tobacco (ST) use is one of the most important public health problems in Southeast Asia. The use of these substances increases the incidence of some cancers and other diseases. The purpose of this review study was to investigate on ST use in Iran. METHODS: A literature search was conducted on PubMed, Google Scholar, and three national databases [Scientific Information Database (SID), IranMedex, and IranDoc] based on the standard search strategy. FINDINGS: Most consumer people lived in Sistan and Baluchestan Province (Zahedan and Chabahar Cities) and Golestan Province, Iran. ST use rates ranged from 11.0% to 45.7% among college students in Sistan and Baluchestan (Zahedan and Chabahar) and Golestan. There are various types of ST consumed in Iran that have been mentioned in various articles, including Pan, Gutka, Nass, Naswar, Biti, and Supari. CONCLUSION: Most studies on ST have been conducted in Sistan and Baluchestan and Golestan Provinces and we need more research for other provinces. Consumption by women is a warning and a threat to women's health in the future. Further studies will be needed to find out more precisely the prevalence of consumption in Iran.

Prioritization of needs among students of University of Medical Sciences: A needs assessment.

INTRODUCTION: The need assessment is a fundamental part of any planning, and almost by neglecting it, the effectiveness of the programs is impossible. The purpose of this study was the prioritization of needs among students of the Iran University of Medical Sciences. MATERIALS AND METHODS: The design study was conducted in two parts; in the first part, the design of the questionnaire was done by qualitative methods. The questionnaires were extracted by interviewing and obtained acceptable validity and reliability. Moreover, the second part created a questionnaire consisting of four categories: education, welfare, economic, and psychological and social. A simple random sampling method was used to select 363 people using the Cochran formula. Finally, 336 people (including 28 people excluded) completed the questionnaire. A questionnaire designed to collect sample data was used and analyzed using version 23 of SPSS. RESULTS: A total of 336 students (26.77 ± 5.45 years) participated in the study. 123 (36.6%) were male and 213 (63.4%) were female. Psychological and social needs of students were prioritized, and educational priorities were ranked second. The findings showed that there was no significant statistical difference between the scores of welfares and psychosocial and educational needs and the gender of the research units (P > 0.05). However, in the mean of economic needs scores, there is a significant statistical difference between the marital status of the research units (P < 0.05). CONCLUSION: The results of our study in the research units showed that the priority of psychosocial needs was more than other needs and the educational priority was the next. According to the results of this study, we suggest that, in future educational and educational planning, policymakers and planners should pay attention to psychological and social issues.

Effect of alginate/carboxyl methyl cellulose composite coating incorporated with clove essential oil on the quality of silver carp fillet and Escherichia coli O157:H7 inhibition during refrigerated storage.

The effects of alginate/carboxyl methylcellulose composite coating incorporated with clove essential oil on quality of silver carp fillet chilled storage (4 + 1 °C) were examined over a period of 16 days. The control samples (c), alginate/carboxyl methylcellulose coating (C-A), alginate/carboxyl methylcellulose composite coating incorporated with clove essential oil (with different concentration 1 and 1.5 %) (C-A + CEO1 % and C-A + CEO 15 % respectively) were analyzed by bacteriological (total viable counts (TVC) and total psychrotrophic counts (TPC)), biochemical (Peroxide value (PV), free fatty acid (FFA), total volatile base nitrogen (TVB-N), and pH) and sensory characteristics. Also, the efficacy of these treatments was investigated in control of the population of Eschershia coli O157:H7 inoculated in silver carp fillet. According to the obtained results, C-A + CEO 1.5 % showed lowest (p < 0.05) and acceptable biochemical, bacteriological and sensory characteristics attributes up to 16 days storage at 4 °C compared to the others. Also, this treated sample was acceptable even at the end of the 16-day storage and it could reduce the population of E. coli O157:H7 below the acceptable level (<2) from day 4 until the end of the storage period. The results indicate Alginate/carboxyl methylcellulose composite coating with clove essential oil might be recommended as a preservative in the meat products.

The adverse effects of methoxsalen on the oogenesis of BALB/c mice.

OBJECTIVE: Methoxsalen is a natural photoactive compound which is found in many seed plants. A number of epidermal proliferative disorders can be treated by methoxsalen along with long wave ultraviolet A (UVA). MATERIALS AND METHODS: In an experimental study, we aimed to demonstrate the effect of methoxsalen, UVA and their combination on oogenesis Balb/C mice. There were two experimental groups and a control group. The experimental groups were composed of i. a short term group with treatment duration of 15 days and ii. a long term group with treatment duration of 5 weeks. Both the long term and short term experimental groups were further subdivided into a UVA group, a methoxsalen group and a methoxsalen plus UVA group. After treatment, mature females in prosterus phase of ovarian cycle were scarified with ether, while their ovaries were removed and prepared for histological studies. RESULTS: Both macro and microscopic studies showed significant anomalies (p<0.05) among experimental group ovaries as compared to control group. The obtained results showed a significant decrease in the following factors: number and diameter of corpus lutei, Graafian follicles, diameter of granulosa cell layer and oocytes, number of primordial and primary and growing follicles, while we observed an increase in number of atretic follicle. Furthermore, our findings confirmed an increase in theca diameter only through UVA treatment. Methoxsalen also reduced circulating estrogen levels in blood serum, significantly. Other cases of teratogenecity, such as follicles with three oocytes and disorganization in corpus luteum cells were observed. CONCLUSION: The result suggests that UVA, methoxsalen and their combination cause health problems and cell injuries.
