Factors predicting oral health behaviors among students age 13-15 years in Shushtar city, Iran.

BACKGROUND: Tooth decay and other oral health (periodontal) diseases are highly prevalent worldwide and present a significant economic burden. Oral health is particularly important for adolescents, as the World Health Organization has identified tooth decay as one of the most pressing global health issues. This study aims to identify predictors of oral health behaviors among students aged 13-15 years in the city of Shushtar, Iran. METHODS: The present research is a cross-sectional study that was conducted during the summer of 2022 on 415 adolescents from the first secondary school in Shushtar. Two standard questionnaires were used to collect data, consisting of demographic information and questions related to measuring awareness, attitude, performance, and self-efficacy regarding oral health behaviors among adolescents. The collected data was analyzed using SPSS 22 statistical software through descriptive statistics, Pearson correlation, and regression analysis. RESULTS: The average scores for awareness, attitude, self-efficacy in brushing teeth, self-efficacy in flossing, self-efficacy in going to the dentist, and adolescents' performance on oral health behaviors are 5.72 ± 2.06, 36.40 ± 6.36, 25.40 ± 7.49, 14.15 ± 6.06, 15.80 ± 5.59, and 14.01 ± 4.02, respectively. CONCLUSION: Based on the results of this study, it can be concluded that adolescents have low levels of awareness, performance, self-efficacy, and a positive attitude towards oral health. Considering the significance of adolescence as a stage for shaping oral health behaviors and their impact on adulthood, it is recommended to increase awareness among adolescents and improve their health behaviors by conducting educational classes in schools.

Determinants of health volunteer training in natural hazard management in Iran.

Both natural and man-made dangers cause bodily harm, as well as social, economic and environmental harm. In order to minimise the complications of these threats, proper training and preparedness are crucial. The purpose of this study was to look at the factors that affect how well-trained healthcare volunteers are for natural hazards in Iran. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses approach, a systematic review of literature on the factors influencing the training of healthcare volunteers in natural hazard published between 2010 and 2020 was conducted. The Google Scholar search engine, PubMed (Medline and Central), Science Direct and Web of Science databases were searched using both individual and combined key phrases. The Strengthening the Reporting of Observational studies in Epidemiology checklist was used to select and evaluate 592 observational and quasi-experimental articles. Finally, the study comprised 24 papers that satisfied the research criteria and made good use of good technique, sample size and adequate tools for validity and reliability. The most useful variables for disaster preparedness were job self-efficacy, strategic decision-making and quality of work-life, job performance, job motivation, knowledge, awareness and health literacy. Contribution: To avoid calamity, a thorough training program is required. Therefore, the most crucial objectives for health education specialists are to identify the factors that determine disaster preparedness, train volunteers and provide fundamental techniques to reduce natural dangers.

Promoting behavior-related low back health in nurses by in-person and social media interventions in the workplace.

BACKGROUND: Nurses are put at high risk of work-related low back pain due to the nature of their work. The aim of this study was to develop and evaluate intervention based on the PRECEDE-PROCEED Model on promoting behaviors of low back health via two educational approaches. METHODS: This study was a community randomized-controlled clinical trial. The educational content was developed with six modules: knowledge, attitude, self-efficacy, reinforcing factors, enabling factors, and behavior. Intervention was delivered by two modes: (1) in-person (n = 60) and (2) social media (n = 60). Data were evaluated by a self-designed questionnaire at baseline, 3, and 6 months. Baseline comparisons between groups were made with Mann-Whitney U Test and T-Test. Comparison of change scores between groups and two delivery types across the three time periods used the mixed between-within subject analysis of variance. RESULTS: A total of 120 nurses received the allocated intervention. All educational component scores increased at 3-months in both groups. At the 6-month follow-up scores increased for enabling factors and behavior in the intervention group, while in the control group all scores increased except for attitude. Based on Bonferroni Post hoc analysis social media was more effective in knowledge, self-efficacy, reinforcing factors, and behavior than the in-person intervention. CONCLUSION: An educational program for low back health based on the PRECEDE-PROCEED model proved effective at improving all components. However, social media was more successful than in-person in the maintenance of behavior over the long term. TRIAL REGISTRATION: IRCT20170313033054N2: 25-02-2018. https://www.irct.ir/trial/25598.

Exploring nurses' experiences of social media and in-person educational interventions for professional development: a qualitative study.

BACKGROUND: Nurses play an important role in health promotion, prevention strategies, and care. Therefore, nurses need to obtain and update their knowledge and skills via appropriate strategies. This study aimed to explore nurses' experiences of receiving social media and in-person education to integrate the findings into practice. METHODS: This was a qualitative study using the directed content analysis approach. A sample of nurses with previous experiences of receiving social media and in-person education participated in the study. They were asked to express their experiences and indicate their preferences. The data were collected based on individual semi-structured interviews. RESULTS: In total 15 participants took part in the study with a mean age of 40.6 ± 8.93 years and work experiences of 15.3 ± 9.21 years. During the process of content analysis, three main themes emerged: Approaches to nursing education and its adoption in the health system, Achieving effectiveness and efficiency in nursing education, and Health care policy and facilitating pathways for nursing education. Participants indicated several barriers to attending an educational program, including motivation, workload, time and place, and hospital politics. CONCLUSION: Overall the findings suggest that regardless of any methods of education nurses cannot actively engage in the educational interventions while on duty. However, the findings suggest that nurses believe that the social media approach might be superior in reducing barriers and making the educational interventions work better.

The effectiveness of social media and in-person interventions for low back pain conditions in nursing personnel (SMILE).

AIM: To compare two educational approaches to reduce low back pain in nurses. DESIGN: A community randomized controlled clinical trial. METHODS: Data were collected with two interventions and a control arm between August 2018 and January 2019. Participants were recruited from three hospitals. Hospital 1 received an in-person educational programme, Hospital 2 received via the website and Hospital 3 received nothing. Statistical analysis was carried out with a follow-up of 3 and 6 months. RESULTS: A total of 180 female nurses with low back pain participated in the study. Dimensions of the quality of life improved over 3 and 6 months, pain and disability decreased over 3 months in both intervention groups and over 6 months in the social media group. CONCLUSION: Two educational approaches can be effective in decreasing pain, disability and improving quality of life. However, the findings suggest that the social media approach was more successful over the long-term and might be a better way to present the programme.

Development and validation of an instrument of occupational low back pain prevention behaviours of nurse.

AIM: To develop and test the psychometric properties of occupational low back pain prevention behaviours questionnaire in nursing personnel. DESIGN: A qualitative and quantitative research design to develop and validate an instrument. METHODS: A qualitative study was conducted from May - October 2017 with 20 participants to generate an item pool. Then, content and face validity was carried out. Next, the questionnaire was distributed among a sample of nurses. In all, 150 nurses participated (mean age 34.1; SD 7.66 years) in the study. Exploratory factor analysis used to determine the factor structure of the questionnaire. Item-scale correlation matrix was provided to examine the construct validity. Internal consistency (Cronbach's alpha) was estimated to assess reliability and intraclass correlation coefficient was calculated to examine stability. RESULTS: Six factors with 30 items emerged from the exploratory factor analysis that jointly accounted for 67.9% of the variance observed. Item-scale correlation matrix showed satisfactory results lending support to construct validity of the questionnaire. The Cronbach's alpha coefficient for the whole scale showed excellent internal consistency (0.92), although this was not true for the knowledge subscale. The intraclass correlation coefficient with a 2-week interval also indicated that the questionnaire had satisfactory stability (0.97). CONCLUSION: This study provides initial support for reliability and validity of the Occupational Low Back Pain Prevention Behaviour Questionnaire. IMPACT: This study offers an instrument to assess low back pain preventive behaviours among nurses. The instrument is useful for nursing personnel and could be used in hospitals and healthcare settings to implement appropriate interventions.

Factors predicting the oral health behaviors of the Iranian students in the District 1 Tehran, Iran

Aim: The purpose of this examination is determining the predictors of oral health behaviors among Iranian students in district 1 Tehran based on the health belief model with added commitment to plan construct. Methods: This cross-sectional study was conducted on 351 four grade female students in the first district of Tehran, Iran in 2017. The multi­stage random cluster sampling method was used to recruit students. The inclusion criteria were being in four ­ graded level of elementary schools of the 1st district in Tehran, being female students aged between 9-11 years and being physically and psychologically healthy student. Logistic regression analysis was used to identify the variables that predict oral health behaviors. Results: Totally, (N= 31.8%) students reported that they were brushing less than twice a day and (N= 55.2% ) students claimed using of dental floss once a week or less than once a day. The results indicated that perceived self-efficacy (OR=1.46, 95% CI=0.57-3.78, P<0.001), commitment to plan (OR=1.13, 95% CI=1.04-1.23, P<0.001) and cues to action (OR=1.42, 95% CI=1.14­1.76, P=0.002) were the significant predicting variables of brushing twice a day, and use of dental floss once a day or more (OR=1.02, 95% CI=0.23-3.53, P=0.003). Conclusion: This study has shown the effectiveness of the health belief model with added commitment to plan construct to predict oral health behavior in female students. Thus, it seems that the model as a acceptable framework for designing training programs to improve oral health behavior in students

Improving prenatal care in pregnant women in Iranshahr, Iran: Applying Health Belief Model.

To determine the effect of an education-based intervention on receiving adequate prenatal care. This randomized, controlled trial was conducted on 90 primiparous pregnant women, referred in Iranshahr, Iran for prenatal care (intervention = 45, control group = 45). The data were collected from February to June 2016 using a questionnaire developed based on the Health Belief Model (HBM). The intervention group received three intervention sessions during the second trimester of pregnancy, and 3 months after intervention, both groups completed a questionnaire. Data were analyzed using independent sample t-tests, chi-squared tests, paired t-test, Pearson and multivariate regression. Unlike the control group, in the intervention group's mean scores for knowledge, variables from the HBM model and frequency of prenatal care significantly differed from pre- to post-intervention (pre-intervention mean = 12.62 ± 2.63, post-intervention mean = 17.71 ± 1.56, (p ˂ 0.05). Self-efficacy was positively correlated with knowledge (r = 0.304, p = 0.02) and adequate prenatal care (r = 0.583, p ˂ 0.001). The constructs of the HBM explained 75% of the variance in frequency of prenatal care in multivariable models. Developing an educational program based on the HBM was effective in the adoptation of prenatal care. Additionally, considering social, economic, and educational follow-up while implementing these programs is recommended.

Effects of Social Support and Self-Efficacy on Maternal Prenatal Cares Among the First-Time Pregnant Women, Iranshahr, Iran.

Objective: Social support and perceived self-efficacy affect health-related behaviors and play an important role on mothers' adaptability with pregnancy. This paper aims to study the impact of educational interventions based on social support and perceived self-efficacy on maternal prenatal care. Materials and methods: The present study is a before after experimental study in which 90 first-time pregnant women were randomly selected and divided into two 45- participants experimental and control groups. Data were collected from 21 January to 20 May 2016. Determining the validity and reliability of the questionnaire, we used the panel of experts and Cronbach's alpha. The data collected from the two groups were compared before and 3 months after intervention and were analyzed by SPSS 18. Results: Unlike the control subjects, there was a significant difference in maternal prenatal cares before and after an educational intervention between the scores of social support and perceived self-efficacy in the experimental group (p < 0.05). Before intervention, the average score of the experimental group was 12.62 ± 2.63 that rose to 17.71 ± 1.56, three months after the educational intervention, which is statistically significant (p < 0.05). There was a direct and positive relation between self-efficacy and maternal prenatal cares (p = 0.000, r = 0.538). Social support and self-efficacy predicted the variance of maternal cares by 69.2%. Conclusion: Developing an educational program based on social support and perceived self-efficacy on maternal prenatal cares is helpful and efficient. The health system, family and society are in charge of making facilities and opportunities to improve social support and perceived self-efficacy in pregnant women, resulting in improved maternal prenatal cares.

Effects of a Theory Based Intervention on Physical Activity Among Female Employees: A Quasi-Experimental Study.

BACKGROUND: Regular physical activity has been highlighted as an important factor in decreasing about 25 factors harmful to health, such as obesity, diabetes, heart failure, depression and osteoporosis. Female office workers, because of the long hours they stay seated in their workplace, are seriously threatened by immobility. The Theory of Planned Behavior has been successfully used several times to predict PA behaviorphysical activity (PA). The TPB studies also have identified perceived behavioral control as the key determinant of walking intentions. OBJECTIVES: The present study aims to assess the effectiveness of an intervention based on TPB to improve attitude, perceived behavioral control, Subjective norms, behavioral intention and PA behavior among female office workers. MATERIALS AND METHODS: The present study is an interventional, quasi-experimental study. Participants were 95 female office workers of the Tehran University that divided randomly in two case and control groups. Using the theory of planned behavior questionnaire and the International physical activity questionnaire, the participants were evaluated before the training and three months after that. The training was provided in the form of four 90-minute training sessions and some electronic messages sent through office automation system once every two weeks. RESULTS: The intervention increased PBC, attitudes, intentions and objectively measured PA behavior. The effects of the intervention on intentions and behavior were mediated by PBC. CONCLUSIONS: The present study has provided some of the data toward understanding determinants of physical activity behavior in female office workers. Specifically, the results suggest that interventions designed to promote physical activity in this population should focus on the development of PBC as well as positive attitude toward PA.

Application of the health belief model and social cognitive theory for osteoporosis preventive nutritional behaviors in a sample of Iranian women.

BACKGROUND: Osteoporosis is the most common metabolic bone disease. The purpose of this study is to investigate the health belief model (HBM) and social cognitive theory (SCT) for osteoporosis preventive nutritional behaviors in women. MATERIALS AND METHODS: In this quasi-experimental study, 120 patients who were women and registered under the health centers in Fasa City, Fars Province, Iran were selected. A questionnaire consisting of HBM constructs and the constructs of self-regulation and social support from SCT was used to measure nutrition performance. Bone mineral density was recorded at the lumbar spine and femur. The intervention for the experimental group included 10 educational sessions of 55-60 min of speech, group discussion, questions and answers, as well as posters and educational pamphlets, film screenings, and PowerPoint displays. Data were analyzed using SPSS 19 via Chi-square test, independent t-test, and repeated measures analysis of variance (ANOVA) at a significance level of 0.05. RESULTS: After intervention, the experimental group showed a significant increase in the HBM constructs, self-regulation, social support, and nutrition performance, compared to the control group. Six months after the intervention, the value of lumbar spine bone mineral density (BMD) T-score increased to 0.127 in the experimental group, while it reduced to -0.043 in the control group. The value of the hip BMD T-score increased to 0.125 in the intervention group, but it decreased to -0.028 in the control group. CONCLUSIONS: This study showed the effectiveness of HBM and constructs of self-regulation and social support on adoption of nutrition behaviors and increase in the bone density to prevent osteoporosis.

Effects of an Osteoporosis Prevention Program Based on Health Belief Model Among Females.

BACKGROUND: Several studies reported the efficacy of osteoporosis prevention interventions in improvement of people's preventive behaviors. However, there are reports that the interventions were not successful in altering osteoporosis health beliefs and preventive behaviors. OBJECTIVES: The current study aimed to assess the effect of a program based on health beliefs model (HBM) on females' health beliefs and performances about osteoporosis preventive behaviors. PATIENTS AND METHODS: This quasi-experimental study was conducted on 120 patients registered in two healthcare centers of Fasa, Fars Province, Iran in 2014. A questionnaire including demographic information and HBM constructs was employed to measure the females' beliefs regarding nutrition and walking performance in prevention of osteoporosis bone mineral density (BMD) measured at the lumbar spine and femur before, immediately after the intervention, and six months after the intervention. Data were analyzed using Chi-square, independent samples t-, Mann-Whitney U tests and repeated measures ANOVA. RESULTS: Immediately and six months after the intervention, a significant increase was found in the intervention group's health beliefs, nutrition, and walking performances to prevent osteoporosis. Six months after the intervention, lumbar spine BMD T-score increased to 0.127 ± 0.061 in the intervention group but reduced to -0.043 ± 0.059 in the control group. Also, hip BMD T-score increased to 0.125 ± 0.088 in the intervention group, but decreased to -0.028 ± 0.052 in control group. CONCLUSIONS: The current study showed the effectiveness of HBM in adoption of nutrition and walking behaviors as well as the increase of bone density to prevent osteoporosis.

Predicting tobacco smoking among male adolescents in Hamadan City, west of Iran in 2014: an application of the prototype willingness model.

BACKGROUND: As adolescent tobacco smoking has become a widespread problem in developing countries, it is time to understand the cognitive determinants of adolescents' decisions to engage in tobacco smoking. This study aimed to investigate the predicting factors associated with tobacco smoking among male adolescents based on Prototype Willingness Model (PWM) as a theoretical framework. METHODS: This descriptive-analytical study was carried out on 810 male adolescents of Hamadan City western Iran, recruited with a multistage sampling method. The data-gathering tool consisted of a questionnaire based on the PWM constructs. Data analysis was performed using SPSS-19 software, by bivariate correlations, liner and logistic regression tests. RESULTS: The prevalence of current tobacco smoking was 17.2%. Behavioral willingness and subjective norms were the most important predictors of behavioral intentions, whereas subjective norms, attitude and prototype were the most important predictors for behavioral willingness. The result obtained from logistic regression analysis revealed that both pathways of PWM constructs [behavioral intention (OR=1.207; 95% CI: 1.13, 1.28) and behavioral willingness (OR=1.334; 95% CI: 1.25, 1.41) were significant predicting factors for tobacco smoking among male adolescents. CONCLUSIONS: The framework of the PWM is applicable and useful in understanding tobacco smoking among male adolescents. In addition, the results revealed the importance of social reaction path when examining adolescents' smoking status.

Belief-based Tobacco Smoking Scale: Evaluating the Psychometric Properties of the Theory of Planned Behavior's Constructs.

BACKGROUND: At present, there are no comprehensive validated instruments for measuring adolescents' beliefs regarding tobacco smoking in the Iranian society. This study aimed to evaluate the validity, reliability and feasibility of the belief-based tobacco smoking scale using the Theory of Planned Behavior's (TPB) constructs as a theoretical framework. METHODS: This cross-sectional validation study was carried out on 410 male adolescents of Hamadan, west of Iran, recruited through multi-stage random sampling method. Reliability was assessed by internal consistency and Intraclass Correlation Coefficient (ICC). In addition, Confirmatory Factor Analyses (CFA) and Exploratory Factor Analyses (EFA) were performed to test construct validity. Content validity was examined using Content Validity Index (CVI) and Content Validity Ratio (CVR). RESULTS: RESULTS obtained from factor analysis showed that the data was fit to the model (X(2)=391.43, P<0.001) and TPB consisted of 22 items measuring seven components which explaining 69.7% of the common variance. The mean scores for the CVI and CVR were 0.89 and 0.80; respectively. Additional anal-yses indicated acceptable results for internal consistency reliability values ranging from 0.55 to 0.92. CONCLUSION: The belief-based tobacco smoking questionnaire is a reliable and valid instrument and now is acceptable and suitable and can be used in future studies.

Farsi Version of the Mammography Self-efficacy Scale for Iranian Women.

BACKGROUND: Self-efficacy is a crucial factor in adopting mammography behavior. A reliable and valid instrument is necessary to measure self-efficacy among Iranian women. OBJECTIVE: The aim of this study is to translate the original version of Champion's Mammography Self-efficacy Scale into Farsi and then to estimate the Farsi version's reliability and validity. METHODS: In a cross-sectional study, 200 women 40 years or older who were referred to health centers in Iran were invited to complete the related questionnaires during an interview. Cronbach's α coefficients and item-total correlations were measured to evaluate the reliability of the scales. Content and face validities were evaluated using the opinions of a panel of experts, and construct validity was estimated through applying confirmatory factor analysis. Logistic regression and χ tests were used to estimate theoretical relationships. RESULTS: In terms of reliability, the internal consistency α was .904 and the test-retest reliability correlation over a 4-week period was 0.624. With regard to the confirmatory factor analysis, the proportion of χ to degrees of freedom was 0.394, giving a P value of .852 and a root-mean-square error of approximation less than 0.001 with confidence intervals of less than 0.001 and 0.018, with a comparative fit index of 1, normed fit index of 0.999, relative fit index of 0.993, and incremental fit index of 1. CONCLUSION: The items that form the self-efficacy measurement scale in the Farsi version are highly reliable and valid. IMPLICATIONS FOR PRACTICE: Healthcare professionals and nursing health communities may apply the instrument to determine women's self-efficacy and to plan appropriate educational interventions, aiming at promoting women's mammography behavior.

The effect of a prevention program based on health belief model on osteoporosis.

BACKGROUND: Osteoporosis is one of the most common metabolic bone diseases. The purpose of this study was to investigate the effect of a prevention program based on health belief model on osteoporosis among women. METHODS: In this quasi-case study, 120 patients (60 cases and 60 control), registered under the health centers in Fasa City, Fars Province, Iran were selected in 2014. A questionnaire consisting of demographic information, Health Belief Model (HBM) constructs was used to measure nutrition and walking performance for prevention of osteoporosis before, immediately after the intervention and six months later. Bone mineral density (BMD) was recorded at the lumbar spine and femur before and six months after intervention. Data were analyzed using SPSS19 via chi-square test, independent t-test, and Repeated Measures ANOVA at significance level of 0.05. RESULTS: Immediately and six months after the intervention, the case group showed a significant increase in the knowledge, perceived susceptibility, perceived severity, perceived benefits, perceived barriers, self-efficacy, internal cues to action, nutrition and walking performance compared to the control group. Six months after the intervention, the value of lumbar spine BMD T-Score in the case group increased to 0.127, while in the control group it reduced to -0.043. The value of the Hip BMD T-Score in the intervention group increased to 0.125 but it decreased to -0.028 in the control group. CONCLUSIONS: This study showed the effectiveness of knowledge, walking and diet on bone mass by HBM model. Hence, these models can act as a framework for designing and implementing educational interventions for the osteoporosis prevention.

Substance use avoidance among Iranian male adolescents: a comparison of three versions of the theory of reasoned action.

The theory of reasoned action (TRA) is one of the most common models in predicting health-related behaviors and is used more often in health education studies. This study aimed to add two control constructs (perceived behavioral control - PBC and self-efficacy - SE) to the TRA and compare them using the structural equation modeling (SEM) for substance use avoidance among Iranian male adolescents in order to find out which model was a better fit in predicting the intention. This was a cross-sectional study carried out in Tehran, Iran. Data were collected from a random sample of high school male students (15-19 years of age) using a questionnaire containing items related to the TRA plus items reflecting two additional constructs (SE and PBC). In all, 433 students completed the questionnaires. The results obtained from SEM indicated a better fit to the data for the TRA with SE compared to the TPB (TRA with PBC) and TRA (χ2/df=2.55, RMSEA=0.072, CFI=0.96, NFI=0.94, NNFI=0.95, SRMR=0.058). Comparing SE and PBC, the results showed that self-efficacy was a better control construct in improving the TRA and predicting substance use avoidance intention (41%). The TRA with SE had a better model fit than TPB and the original version of the TRA.

Predictors of Physical Activity among Adolescent Girl Students Based on the Social Cognitive Theory.

BACKGROUND: The importance of increasing adolescence girl's level of physical activity is recognized as a priority for having a healthy lifestyle. However, adolescent girls especially Iranian, are at high risk for physical inactivity. Social Cognitive Theory (SCT) is a successful theory to explain physical activity behavior. The aim of this study was to determine the predictors of physical activity based on the SCT. METHODS: This cross-sectional study was conducted among 400 adolescent girls (15-16 yr old) in Tehran, Iran (2013). The participants were randomly chosen with multistage sampling. The SCT constructs consisted of self-efficacy, self-regulation, social support, outcome expectancy, and self-efficacy to overcoming impediments. Statistical analysis was carried out applying SPSS: 16, LISREL 8.8. Stepwise regression was used to test predictors of behavior. Pearson correlation was assessed. RESULTS: Self efficacy to overcoming impediments was the main construct to predict physical activity (Beta=0.37). Other determinants were self-efficacy (Beta=0.29), family support (beta=0.14), outcome expectancy (beta=0.13), friend support (beta=0.12), and self-regulation (beta=0.11), respectively. In general, the SCT questionnaire determined 0.85 variation of physical activity behavior. All of the constructs had direct significant relation to physical activity behavior (P<0.001). CONCLUSIONS: The constructs of SCT provide a suitable framework to perform promoting physical activity programs and self-efficacy to overcoming impediments and self-efficacy are the best predictors of physical activity in adolescent girls.
