The Effect of Educational Intervention Based on Health Belief Model and Social Support on Promoting Skin Cancer Preventive Behaviors in a Sample of Iranian Farmers

Using the health beliefs model to implement mobile puberty health education in Iranian adolescent boys: a randomized controlled trial

Introduction

Given boys' low health knowledge and their unhealthy behavior during puberty, which can cause many physical, mental, and psychological problems, it is important to prevent these complications. This study was therefore aimed to determine the efficacy of a mobile health educational intervention based on the Health Beliefs Model (HBM) on Iranian adolescent boys.

Materials and methods

This randomized controlled trial involved junior high school boys (n = 148) in Iran studying during the 2020-2021 school year. Educational content concerning healthy behaviors during puberty (e.g., the importance of bathing) was developed based on HBM and sent to the intervention group via mobile phone. HBM addresses multiple factors (e.g., perceived disease risk) that explain health behaviors. The intervention was delivered in five sessions over four weeks using real-time Internet communication and texting. The control group did not receive any intervention. One school was randomly selected from each of the four districts of the study site. The schools were then randomized into intervention and control groups. The boys were then randomly selected from each school to participate in the study. Data collected at baseline and 2-month follow-up assessments included demographic information, health knowledge (e.g., physical changes during puberty), health behaviors (e.g., bathing), and HBM constructs (e.g., self-efficacy to perform healthy behaviors). Data analysis was done using the chi-square, independent and paired t-tests, and analysis of covariance (ANCOVA).

Results

The two groups did not differ in terms of demographic characteristics. Before the intervention, the two groups were slightly different in terms of knowledge, health behavior, and HBM constructs. Following the intervention, the scores of the intervention group improved significantly (p < 0.05). After adjusting for pre-intervention knowledge, HBM, and health behavior scores, the intervention group remained superior to the control group in terms of improvement of knowledge, HBM constructs, and healthy behaviors (p < 0.05). Effect sizes ranged from medium to large (0.25-0.86).

Conclusion

Mobile phone education based on the HBM is efficacious in encouraging healthy behavior in boys during puberty. Organizations interested in encouraging healthy behaviors in boys should consider the use of such a program.

Public Health Messaging to Address Indoor Tanning: A Scoping Review

Indoor tanning (IT) is an avoidable skin cancer risk. Although numerous communication interventions have been assessed for IT deterrence, less attention has been paid to the persuasive messages within these interventions. This scoping review summarizes the current peer-reviewed literature on persuasive messages for IT. Overall, 20 articles (21 studies) were included. Most were experimental or quasi-experimental and conducted in the US. Participants were mostly young women who had tanned indoors before. Few studies evaluated persuasive theme; in those that did, health and appearance themes were effective. Narrative and statistical evidence formats were also effective. The included studies also supported normative messages, loss-framed messages, and images. Improved reporting on message design and evaluation would be beneficial for future evidence synthesis. Our understanding of persuasive messages for IT has expanded in recent years, but more research is needed to optimize them.

Factors Associated With Sun Protection Behaviors Among Childhood Cancer Survivors

BACKGROUND

Childhood cancer survivors (CCS) are at increased risk of developing skin cancer. Engaging in sun-protective behaviors may ameliorate that risk, but prior work shows that survivors engage in suboptimal levels of sun-protective behaviors. Guided by the Health Belief Model (HBM), this study evaluated factors associated with sun-protective behavior among CCS.

METHODS

This is a secondary analysis of a survey study of 94 adult survivors of childhood cancer recruited from a long-term follow-up clinic. Participants reported their sun protection habits, skin type/sensitivity, barriers to sun protection, and perceived severity and susceptibility of getting skin cancer. Descriptive statistics were used to describe the prevalence of sun protection behaviors and hierarchical linear regression was used to evaluate predictors of sun protection behavior following the HBM.

RESULTS

On average, CCS engaged in moderate levels of sun-protective behaviors ( M =2.53; SD=0.59). Hierarchical linear regression indicated that fair skin type ( P =0.02) and higher perceived susceptibility relative to noncancer survivors ( P =0.02) were associated with increased sun protection behaviors. Perceived barriers to sun protection were marginally significant ( P =0.09), whereas other constructs from the HBM did not contribute significantly to the model.

CONCLUSIONS

Although CCS are at increased risk of developing skin cancer, they engage in suboptimal levels of sun protection behaviors. Findings suggest that interventions to educate survivors about their unique risk of skin cancer and effective prevention behaviors are needed.

Skin Cancer-Related Health Behavior Interventions in the Context of the Health Belief Model

The incidence of skin cancer is increasing around the world every year. Although there are many reasons for the occurrence of skin cancer, UV radiation caused by sunlight is seen as the most important factor. Therefore, reducing exposure to UV radiation should be a top priority for skin cancer prevention. In addition, different demographic features also affect the amount of UV exposure. These include age, gender and professional groups. On the other hand, people can be exposed to UV radiation voluntarily. Sunbathing or using tanning devices can be shown as examples for this. For these reasons, interventions to reduce exposure to UV radiation should focus on demographic features and the desire to tan. At the same time, it is emphasized in the literature that theory-based and systematic interventions are more effective than others. In this context, we think that the Health Belief Model, which is an effective psychosocial model for health behaviors, will be useful in developing sun protection behaviors. In this review, interventions based on the Health Belief Model in the context of tanning behavior, age, gender, and outdoor activities for the prevention of skin cancer and the improvement of sun protection behaviors have been discussed.

Predicting Covid-19 preventive behaviors based on constructs of health belief model

INTRODUCTION AND OBJECTIVE

The prevalence of Covid-19 has become a clinical threat worldwide. However, knowledge about this new virus is limited. Therefore, this study was conducted to determine the preventive behaviors of Covid-19 based on the constructs of health belief model (HBM) in the clients of health centers in Zabol, Iran.

METHODS

This descriptive-analytical (cross-sectional) study was performed on 160 people referring to health centers in Zabol by the available method. A researcher-made questionnaire was used to collect data. Data were analyzed using SPSS20 software and appropriate statistical tests.

RESULTS

A positive and significant correlation was observed between preventive behaviors of Covid-19 and perceived benefit constructs (r = 0.29, P = 0.0001) and self-efficacy (r = 0.39, P = 0.0001). HBM constructs were able to predict about 36% of the variance of Covid-19 disease preventive behaviors, with self-efficacy (B = 0.134) being the strongest predictor.

CONCLUSION

Since no specific and definitive treatment for Corona has been found yet, taking preventive measures can be the best way to prevent the spread of this disease in the community. Therefore, this can be achieved by raising awareness and preventive behaviors through health education.

The effect of Orem-based self-care education on improving self-care ability of patients undergoing chemotherapy: a randomized clinical trial

Background

Cancer is a frightening disease. Therefore, the care of cancer patients is very complex. This study aimed to investigate the effect of the education based on Orem’s self-care model on self-care abilities of the patients undergoing chemotherapy in Shafa Hospital in Ahvaz city, Iran.

Methods

This randomized clinical trial was carried out in 2018 on 100 cancer patients undergoing chemotherapy, who referred to Shafa Hospital in Ahvaz city, Iran. The sampling method was simple and the subjects were randomly divided into two experimental and control groups (50 in the experimental and 50 in the control group). The study outcome was the self-care ability of the patients measured before and 2 months after the intervention by the control and experimental groups. The educational intervention consisted of five 60-minute sessions (one session per week) held as educational and counseling ones through group, face-to-face and individual training based on the identified needs of the patients in the experimental group at Shafa Hospital Chemotherapy Department. To collect data, two questionnaires [the assess and identify the conceptual pattern of Orem questionnaire and the Self-care capacity assessment (ESCI)]were used. Statistical data were entered into SPSS software version 20 and analyzed by chi-square, independent t-test and paired t-test.

Results

The mean and standard deviation of age was 35.06 ± 14.51 in the control group and 31.72 ± 15.01 in the experimental group. The results of the independent t-test showed that before the educational intervention, there was no significant difference between the two groups in terms of the mean self-care (P = 0.38). But after the intervention, a significant difference was found between the mean self-care scores of the experimental and control groups (P = 0.001).

Conclusion

Application of Orem’s self-care model led to increased self-care ability of the cancer patients undergoing chemotherapy. Therefore, it is recommended that this model be included in the routine programs of chemotherapy departments.

Investigating the Adoption of Precautionary Behaviors Among Young Rural Adults in South Iran During COVID-19

COVID-19 is an unprecedented challenge for public health worldwide. Reducing the incidence of the disease requires protective measures to prevent virus transmission. Understanding those factors influencing preventive behavior is the first step in preventing the spread of the disease. This study investigates factors affecting youth intention and preventive behaviors in the face of COVID-19 through the health belief model by using a cross-sectional survey collected through an online questionnaire. The sample comprises 304 rural youth in South Iran who were selected through a random sampling technique. The results reveal that perceived severity, perceived benefits, public health beliefs, perceived self-efficacy, and the cue to act positively and significantly affect preventive behaviors. The model explains 59% of variance changes in rural youth preventive behaviors during COVID-19. Cue to action is the strongest and self-efficacy was the weakest determinant of youth's preventive behavior. This study confirms that the HBM framework has appropriate predictive power and is an effective tool for investigating preventive behaviors during COVID-19. These results provide important policy implications for the development of policies that aim to avoid the further spread of COVID-19 between young citizens.

Testing the Effectiveness of the Health Belief Model in Predicting Preventive Behavior During the COVID-19 Pandemic: The Case of Romania and Italy

We use a cultural psychology approach to examine the relevance of the Health Belief Model (HBM) for predicting a variety of behaviors that had been recommended by health officials during the initial stages of the COVID-19 lockdown for containing the spread of the virus and not overburdening the health system in Europe. Our study is grounded in the assumption that health behavior is activated based on locally relevant perceptions of threats, susceptibility and benefits in engaging in protective behavior, which requires careful attention to how these perceptions might be structured and activated. We assess the validity of the HBM in two European countries that have been relatively understudied, using simultaneous measurements during acute periods of infection in Romania and Italy. An online questionnaire provided a total of (N = 1863) valid answers from both countries. First, to understand individual difference patterns within and across populations, we fit a General Linear Model in which endorsement was predicted by behavior, country, their interaction, and a random effect for participants. Second, we assess the effect of demographics and health beliefs on prevention behaviors by fitting a multi-group path model across countries, in which each behavior was predicted by the observed health belief variables and demographics. Health beliefs showed stronger relationships with the recommended behaviors than demographics. Confirming previously reported relationships, self-efficacy, perceived severity, and perceived benefits were consistently related to the greater adoption of individual behaviors, whereas greater perceived barriers were related to lower adoption of health behaviors. However, we also point to important location specific effects that suggest that local norms shape protective behavior in highly contextualized ways.

Application of protection motivation theory (PMT) on skin cancer preventive behaviors amongst primary school students in rural areas of Fasa city-Iran

Background

Considering that exposure to sunlight in childhood and adolescence has an important role in skin cancer, so it seems that training protective behaviors in this period is more effective.

Objectives

To survey the application of protection motivation theory (PMT) on skin cancer preventive behaviors among students in rural areas of Fasa city, Iran.

Methods

This study was done in two stages: Phase I of this study, the descriptive-analytic and cross-sectional study was conducted in 2018 to investigate the predictive value of the protection motivation theory on skin cancer preventive behaviors. In the second stage, a quasi-experimental interventional study was conducted on 400 primary school students in 2019. The educational intervention was performed in the experimental group for 8 sessions. Data were collected using a demographic information questionnaire and protection motivation theory before and six months after the intervention.

Results

The constructs of protection motivation theory predicted 58.6% of skin cancer preventive behaviors. The results indicated that there was no significant difference between the two groups in terms of knowledge, perceived sensitivity, perceived severity, reward, fear, protection motivation, response efficacy, self-efficacy, response costs, and the skin cancer preventive behaviors in before the intervention (p > 0.05). However, six months after the intervention, the experimental group showed a significant increase in each of the mentioned constructs and skin cancer protective behaviors (p < 0.05).

Conclusion

This study showed the effectiveness of the intervention based on the PMT constructs in adoption of skin cancer preventive behaviors in 6 months’ post intervention in primary school students.

Modified PNN classifier for diagnosing skin cancer severity condition using SMO optimization technique

<abstract> <p>Skin cancer is a pandemic disease now worldwide, and it is responsible for numerous deaths. Early phase detection is pre-eminent for controlling the spread of tumours throughout the body. However, existing algorithms for skin cancer severity detections still have some drawbacks, such as the analysis of skin lesions is not insignificant, slightly worse than that of dermatologists, and costly and time-consuming. Various machine learning algorithms have been used to detect the severity of the disease diagnosis. But it is more complex when detecting the disease. To overcome these issues, a modified Probabilistic Neural Network (MPNN) classifier has been proposed to determine the severity of skin cancer. The proposed method contains two phases such as training and testing the data. The collected features from the data of infected people are used as input to the modified PNN classifier in the current model. The neural network is also trained using Spider Monkey Optimization (SMO) approach. For analyzing the severity level, the classifier predicts four classes. The degree of skin cancer is determined depending on classifications. According to findings, the system achieved a 0.10% False Positive Rate (FPR), 0.03% error and 0.98% accuracy, while previous methods like KNN, NB, RF and SVM have accuracies of 0.90%, 0.70%, 0.803% and 0.86% correspondingly, which is lesser than the proposed approach.</p> </abstract>

The Effect of Educational Intervention Based on PRECEDE Model on Health Promotion Behaviors, Hope Enhancement, and Mental Health in Cancer Patients

In this experimental study, 200 cancer patients (100 subject in experimental group and 100 subjects in control group) referred to Amir Oncology Hospital in Shiraz were investigated. Educational intervention for experimental group consisted of 12 educational sessions for 50 to 55 minutes. A questionnaire including demographic information, PRECEDE constructs (knowledge, attitude, self-efficacy, enabling factors, and social support), was used to measure health promotion behaviors, patients' hope, and mental health before and 6 months after intervention. Six months after intervention, experimental group showed significant increase in knowledge, attitude, self-efficacy, enabling factors, social supports, health promotion behaviors, patients' hope, and mental health compared to the control group. This study showed the effectiveness of intervention based on PRECEDE constructs in mentioned factors 6 months after intervention. Hence, this model can act as a framework for designing and implementing educational intervention for health promotion behaviors of cancer patients.

Testing Multi-Theory Model (MTM) in Explaining Sunscreen Use among Florida Residents: An Integrative Approach for Sun Protection

Florida residents have the second highest incidence of skin cancer in the nation. Sunscreen usage was found to be the one of the most effective integrative health approaches for reducing risk of skin cancer. Given the limited information on the likelihood of adopting and continuing sunscreen usage behavior, this cross-sectional study aimed to examine the correlates of initiating and sustaining sunscreen usage behavior among Florida dwellers, using the fourth-generation, multi-theory model (MTM) of behavior change. A web-based survey containing 51 questions was emailed to Florida residents aged 18 years or above, who were randomly selected from the state voter file. Psychometric validity of the survey instrument was established using structural equation modeling, and Cronbach’s alpha values were calculated for assessing the internal consistency. An independent-samples-t-test and hierarchical multiple regression tests were used to analyze the data. The results indicated that participants who engaged in sunscreen usage behavior, participatory dialogue (β = 0.062, p < 0.05), behavioral confidence (β = 0.636, p < 0.001), and changes in the physical environment (β = 0.210, p < 0.001) were statistically significant and accounted for 73.6% of the variance in initiating sunscreen usage behavior. In addition, the constructs of emotional transformation (β = 0.486, p < 0.001) and practice for change (β = 0.211, p < 0.001), as well as changes in the social environment (β = 0.148, p < 0.001) were significant predictors of maintaining sunscreen usage behavior and contributed to 59% of variance in sustenance. These findings offer a valuable insight regarding the applicability of MTM models to guiding public health interventions promoting sunscreen usage and preventing UV radiation risk and related skin cancer.

The effect of nutrition education based on PRECEDE model on iron deficiency anemia among female students

Background

Iron deficiency anemia disrupts the concentration of adolescent girls; reduces their academic achievement, productivity, and physical strength, and increases the risk of infection. This research aim was to evaluate the effectiveness of the PRECEDE model nutrition education on iron deficiency anemia among female students of Fasa City, Fars Province, Iran.

Methods

This quasi-experimental study was done on 160 students (80 experimental and 80 control groups) who were selected using a random sampling method in Fasa City, Fars Province, Iran, in 2018–2019. The educational intervention included six sessions based PRECEDE model for 45 or 50 min. A scale of this study consisted of two parts; demographic information, and PRECEDE constructs were used to determine the nutritional behaviors status concluding preventing iron deficiency anemia and hemoglobin, hematocrit, and ferritin blood level in two (before and 4 months after intervention) times.

Results

In the experimental group of the students the mean age was 13.85 + 1.72 years and in the controlled group was 13.60 + 1.81 years. Moreover, there was no significant difference in the PRECEDE constructs, and nutritional behaviors preventing iron deficiency anemia before the intervention in two groups of study. However, the experimental group showed a significant increase 4 months after the intervention. Also, there was no significant difference in the mean score of hemoglobin, hematocrit, and ferritin blood level between the two groups before the intervention. However, in ferritin level, a significant increase was shown in 4 months after the intervention in the experiential group.

Conclusions

Based on results, the nutrition intervention education base on PRECEDE model has a positive effect to improve iron deficiency anemia preventive behaviors in female students.

The effect of educational intervention based on health belief model and social support on testicular self-examination in sample of Iranian men

BACKGROUND

Testicular Self-Examination (TSE) causes earlier diagnosis of Testicular cancer (TC). Hence, all men aged between15 to 35 years should perform TSE every month. This study aims to survey the effect of educational intervention based on health belief model and social support on testicular self-examination in men aged between 15 to 35 years of Fasa City, Fars province, Iran.

METHODS

In this quasi-experimental study, 200 men (100 in the experimental group and 100 in the control group) in Fasa City, Fars, Iran, were conducted from June 2018 to August 2019. The educational intervention for the experimental group consisted of six training sessions (testicular cancer, its prevalence and types, its risk factors, symptoms, infected areas, diagnosis, side-effects and its severity, understanding about testicular self-examination and its importance, benefits, and barriers of self-examination and correct way of doing TSE were discussed, role of social support). A questionnaire consisting of demographic information, knowledge, HBM construct, and social support was used to measure testicular self-examination before, 3 months after the intervention, and 6 months later. Data were analyzed using SPSS-22 via chi-squared, independent samples t-test, Mann-Whitney, and repeated measures ANOVA at a significance level of 0.5.

RESULTS

The mean age of the men was 27.26 ± 3.16 years in the experimental group and 27.39 ± 3.12 years in the control group. Three months after the intervention and 6 months after the intervention, the experimental group showed a significant increase in knowledge, perceived susceptibility, perceived severity, perceived benefits, self-efficacy, cues to action, social support, and testicular self-examination performance compared to the control group.

CONCLUSION

This study showed the effectiveness of the intervention based on the HBM constructs and social support in the adoption of testicular self-examination in 3 and 6 months post-intervention in men aged between 15 to 35 years. Hence, these models can act as a framework for designing and implementing educational interventions for testicular self-examination.

Effectiveness of Sun Protection Interventions Delivered to Adolescents in a Secondary School Setting: A Systematic Review

Aim

The aim of this systematic review is to summarise the evidence of the effectiveness of interventions targeted to adolescents (13 to 18 years inclusive) and delivered in a secondary school setting with the purpose of improving sun protection behaviour, reducing ultraviolet radiation (UVR) exposure, and/or improving physiological outcomes related to UVR exposure (such as erythema or naevi development).

Methods

Peer-reviewed journal articles were identified from seven database searches (Cochrane, Embase, CINAHL, Scopus, Medline, PsycInfo, and Web of Science) to January 2020, forward citation searches of relevant articles, and monitoring of WHO INTERSUN UVR list server for recent publications. Relevant articles were collected and critically analysed using the Effective Public Health Practice framework. Two reviewers independently reviewed, and when deemed eligible, extracted data and performed quality appraisals for each study.

Results

Thirteen studies met the criteria for inclusion in the review. There were no studies that met a “strong” quality rating, five received a “moderate” quality rating, and eight studies a “weak” quality rating. Three of those with a moderate rating found evidence for effectiveness. The most promising interventions overall (including the pilot/uncontrolled studies) were those that moved beyond a pure health education approach and used innovative approaches such as the provision of shade, or use of technology (e.g., appearance-based apps or real-time ultraviolet index (UVI) monitors).

Conclusions

There is a lack of high-quality published studies investigating the interventions delivered in a secondary school setting to protect students from UVR. The evidence could be strengthened if researchers used consistent, standardised outcome measures for sun protection exposure and behaviour. Other factors limiting the strength of evidence were short follow-up times (largely less than 6 months) and/or nonrobust study design.

Factors Affecting Public Adoption of COVID-19 Prevention and Treatment Information During an Infodemic: Cross-sectional Survey Study

BACKGROUND

With the spread of COVID-19, an infodemic is also emerging. In public health emergencies, the use of information to enable disease prevention and treatment is incredibly important. Although both the information adoption model (IAM) and health belief model (HBM) have their own merits, they only focus on information or public influence factors, respectively, to explain the public's intention to adopt online prevention and treatment information.

OBJECTIVE

The aim of this study was to fill this gap by using a combination of the IAM and the HBM as the framework for exploring the influencing factors and paths in public health events that affect the public's adoption of online health information and health behaviors, focusing on both objective and subjective factors.

METHODS

We carried out an online survey to collect responses from participants in China (N=501). Structural equation modeling was used to evaluate items, and confirmatory factor analysis was used to calculate construct reliability and validity. The goodness of fit of the model and mediation effects were analyzed.

RESULTS

The overall fitness indices for the model developed in this study indicated an acceptable fit. Adoption intention was predicted by information characteristics (β=.266, P<.001) and perceived usefulness (β=.565, P<.001), which jointly explained nearly 67% of the adoption intention variance. Information characteristics (β=.244, P<.001), perceived drawbacks (β=-.097, P=.002), perceived benefits (β=.512, P<.001), and self-efficacy (β=.141, P<.001) jointly determined perceived usefulness and explained about 81% of the variance of perceived usefulness. However, social influence did not have a statistically significant impact on perceived usefulness, and self-efficacy did not significantly influence adoption intention directly.

CONCLUSIONS

By integrating IAM and HBM, this study provided the insight and understanding that perceived usefulness and adoption intention of online health information could be influenced by information characteristics, people's perceptions of information drawbacks and benefits, and self-efficacy. Moreover, people also exhibited proactive behavior rather than reactive behavior to adopt information. Thus, we should consider these factors when helping the informed public obtain useful information via two approaches: one is to improve the quality of government-based and other official information, and the other is to improve the public's capacity to obtain information, in order to promote truth and fight rumors. This will, in turn, contribute to saving lives as the pandemic continues to unfold and run its course.

The Effect of an Educational Intervention Based on PRECEDE Model on Oral Cancer Prevention Behaviors in Hookah Users

Educational intervention about oral cancer prevention is essential for all people, especially in hookah users. The aim of this study is investigating the effect of an educational intervention based on PRECEDE model on oral cancer prevention in hookah users living in Fasa, Fars Province, Iran, in 2017-2018. In this quasi-experimental study, 360 hookah users were selected and divided into experimental and control groups (180 subjects for each group). Educational intervention was performed for experimental group in 12 sessions. A questionnaire consisting of items evaluating demographic information and PRECEDE model constructs (knowledge, attitude, self-efficacy, enabling factors, and reinforcing factors) was used to measure oral cancer prevention behaviors and nicotine dependency of subjects before and 6 months after intervention. Obtained data were analyzed by SPSS-22 software through paired t test, independent t test, and chi-square test at significance level of P < 0.05. Six months after intervention, experimental group showed significant increase in knowledge, attitude, self-efficacy, enabling factors, reinforcing factors, oral cancer prevention behaviors, and reduction of nicotine dependency compared with control group. This study showed the efficiency of educational intervention based on PRECEDE model in adoption of oral cancer prevention behaviors and reduction of nicotine dependency of hookah users 6 months after intervention.

Some at Risk for COVID-19 Are Reluctant to Take Precautions, but Others Are Not: A Case From Rural in Southern Iran

Little is known about the evaluative and cognitive foundations for adopting preventive measures to reduce the spread of COVID-19. Recognizing the existence of a gap in the knowledge describing the intention and behavior of participating in health measures, this study investigated the drivers that contribute to the intention to take health protective measures among 305 rural youth from the Dashtestan Region, Bushehr Province, and southern Iran, reached through an online survey. Protection motivation theory (PMT) served as the theoretical framework for the study. It was able to forecast variation in intentions and behaviors with accuracies of 39 and 64%, respectively. Furthermore, the variables of response efficiency, perceived severity, and self-efficacy had a positive and significant effect on protective intentions. Additionally, perceived severity, self-efficacy, and intention produced a positive and significant impression on behaviors, with most of the behavioral variance being accounted for by intention, as was hypothesized. In conclusion, it is suggested that health development including training measures that take account of both the concrete issues of health resources and technologies and of more abstract ones, such as mindset readiness, are important for engagement in positive health care behaviors. Accordingly, training-based interventions for rural youth should be contemplated, with the object of changing their intentions.

Effects of health beliefs, social support, and self-efficacy on sun protection behaviors among medical students: testing of an extended health belief model

Sun protection behaviors (SPB) are important modifiable risk factors for skin cancer. As the most common malignancies in the world, skin cancers account for significant morbidity, mortality, and economic burden. Physicians play a key role in educating patients about proper SPB. Medical education provides the foundation for physician understanding of SPB and future patient education. The Health Belief Model (HBM) is a theoretical model that offers constructs to help explain health behaviors. This cross-sectional study examined a convenience sample of 186 medical student to assess their engagement in SPB through the lens of the 6 HBM constructs and social support. Overall, we found engagement in SPB among our cohort to be low. About 70.4% report never using wide-brimmed hats and only 44.6% often or always use sunscreen. Hierarchical multiple regressions were performed in three blocks to analyze the relationship between the independent variables (HBM constructs and social support) and dependent variable (SPB) after controlling for the influence of demographic covariates. In our health constructs model, beliefs about susceptibility, benefits minus barriers, and self-efficacy were found to be significant predictors of engaging in SPB. Addition of social support in the final model did not significantly improve prediction of SPB engagement. These findings support use of educational programs based on HBM for the improvement of SPB among medical students.

Mapping Canadian Men's Recent and Intended Health Behavior Changes Through the Don't Change Much Electronic Health Program

Background

Although evaluation studies confirm the strong potential of men’s electronic health (eHealth) programs, there have been calls to more fully understand acceptability, engagement, and behavior change to guide future work. Relatedly, mapping of behavior changes using health promotion theories including the transtheoretical model (or stages of change) has been recommended to build a translatable empirical base to advance design and evaluation considerations for men’s eHealth programs.

Objective

This study aimed to use a benchmark sample as a reference group to map the recent and intended health behavior changes in Canadian men who use the Don’t Change Much (DCM) eHealth program. The hypothesis being tested was that increased exposure to DCM would be positively associated with men’s recent and intended health behavior changes.

Methods

DCM users (n=863) were sampled for demographic data and self-reported recent and intended health behavior changes. Respondents also reported their usage (frequency and duration) for each of the 3 DCM components (web, newsletter, and social media) and were allocated to limited exposure (257/863, 29.8%), low exposure (431/863, 49.9%), and high exposure (175/863, 20.3%) subgroups. A benchmark sample (n=2000), comprising respondents who had not accessed DCM provided a reference group. Bivariate analysis of recent and intended health behavior changes and DCM exposure levels were used to compute the strength of association between the independent variables (exposure levels) and the 10 categorical dependent variables (recent and intended health behavior changes). Binary logistic regression models were computed for each of the 10 recent and intended health behavior changes. Linear regression was used to model the association between the number of recent and intended changes and the level of exposure to DCM.

Results

Compared with the benchmark reference group, DCM high-exposure respondents had significantly increased odds for 9 of the 10 health behavior changes, with the largest effect size observed for Changed diet or Improved eating habits (odds ratio [OR] 5.628, 95% CI 3.932-8.055). High-exposure respondents also had significantly increased odds for 9 intended health changes, with the largest effect sizes observed for Reduce stress level (OR 4.282, 95% CI 3.086-5.941). Moderate effect size (goodness of fit) was observed for increased total number of recent (F_12,2850=25.52; P.001; adjusted R²=.093) and intended health behavior changes (F_12,2850=36.30; P.001; adjusted R²=.129) among high-exposure respondents.

Conclusions

DCM respondents contrasted the predominately precontemplative benchmark sample mapping across the contemplative, preparation, and action stages of the transtheoretical health behavior change model. Almost 10% of variation in the recent and 13% of variation in the intended health behavior changes can be explained by DCM exposure and demographic factors, indicating the acceptability of this men’s eHealth resource.

Effectiveness of Health Belief Model on Oral Cancer Prevention in Smoker Men

The purpose of the present study is investigating the effect of educational intervention based on health belief model (HBM) on oral cancer prevention in smoker men. This is a quasi-experimental study carried out on 200 smoker men with the age of 40 or older (100 subjects for the experimental group and 100 subjects for control group) resident in Fasa City, Fars Province, Iran, in 2017-2018. The educational intervention for the experimental group included seven educational sessions for 50 or 55 min-based HBM. A questionnaire consisted of items about demographic information, knowledge, HBM constructs (perceived susceptibility, severity, benefits, barriers, self-efficacy, and cues to action) was used to measure the oral cancer prevention before and 6 months after the intervention. The mean age of the men was 51.35±8.41 years in the experimental group and 52.28±8.09 years in the control group. Based on the obtained results, significant enhancement is observed in average scores of knowledge, perceived susceptibility, severity, benefits, self-efficacy, cues to action, and oral cancer prevention behaviors in experimental group; however, no significant changes are observed in average scores of knowledge, perceived susceptibility, severity, benefits, self-efficacy, cues to action, and oral cancer prevention behaviors of control group. Also, results indicated that, the educational program based on HBM model have positive effect on oral cancer prevention with the improvement of subject's knowledge, perceived susceptibility, severity, benefits, and self-efficacy.

The Application of PRECEDE Model on Preventing Osteoporosis in Women

The aim of this study is investigating the efficiency of educational intervention based on PRECEDE model on promotion of osteoporosis prevention behaviors in women. This quasi-experimental study was conducted on 200 women registered in two health centers of Fasa city, Fars province, Iran in 2017 to 2018. A questionnaire including items evaluating demographic information and PRECEDE model constructs was used for measuring nutrition and walking performance of studied women in osteoporosis prevention before and 12 months after intervention. Bone mineral density (BMD) was recorded at the lumbar spine and femur before and 12 months after intervention. One year after intervention, the intervention group showed a significant increase in knowledge, attitude, self-efficacy, reinforcing factors, enabling factors, nutrition, and walking performance compared to the control group. Also, the value of lumbar spine and hip BMD T-Score of the intervention group was increased, while this value was reduced in the control group. Our findings showed that educational interventions based on PRECEDE model can positively affect prevention behaviors from osteoporosis by improving subjects' knowledge, attitude, enabling factors (resources such as health care access and services that can provide motivation for prevention behaviors from osteoporosis in women), self-efficacy, and reinforcing factors.

Examining the effect of implementation of the nursing process on students' health behaviors

Introduction The nursing process is a method for solving the problems used to meet the health and care needs of individuals. Using the nursing process enables nurses to use critical thinking for clinical judgment and their care activities. Thus, the present study was conducted to specify the effect of the implementation of the nursing process on students' health behaviors. Materials and methods The population was first-year high school girl students in Kurdistan in 2016-2017 that comprised 90 students. The questionnaire used was one for the health needs of adolescent girls and was a standard questionnaire with 65 questions. The purpose was to evaluate the health needs of girls from different aspects (mental health, emotional needs, social health needs, educational needs, physical health needs, belief needs). Students were randomly assigned into experimental and control groups and nursing-based interventions were done for the experimental group. Data were analyzed in SPSS. Results The results showed no significant differences between students' health behaviors before the implementation of the nursing process, but after performing the intervention according to the implementation of the nursing process, the status of observing the students' health behaviors significantly improved. Conclusion Given the positive effect of the nursing process on enhancing students' health behaviors, this type of nursing intervention should be done in other studies and in clinics to enhance the health of the students.
