Background and Objectives: Fall is one of the main reasons for serious injuries in workplaces. Protective measures are not frequently used by farmers and farm workers. In Iran, there are no adequate data in recognizing the various effective factors of falls from height in the agricultural sector. Thus, we used the PRECEDE model to recognize causes and factors which can affect the acceptance of the protective measures for the prevention of fall from the walnut tree. Materials and Methods: From July until November 2018, a cross-sectional research was conducted in Tuyserkan County in the west of Iran among 222 farm workers and farmers from 12 villages. A questionnaire was developed to measure demographic features, history of injuries, and constructs recommended in the PRECEDE model. Data were gathered by face-to-face interviews. Results: Predisposing factors (β =0.348, t = 5.116), enabling factors (β =0.131, t = 3.672), and reinforcing factors (β =0.164, t = 2.128) had a positive impact on protective measures, with an explained variance of 35.3%. In this study, the goodness-of-fit value was obtained as 0.455, indicating an excellent overall fit of the model to the data. Conclusions: The results of this research recognized the causes of protective measures among farmers and farm workers. Our findings suggest that the PRECEDE model could help as a guide for developing a more effective intervention for the prevention of fall from the walnut tree.

| Introduction|| |
Fall is one of the main reasons for fatal injuries in the workplace. Fall is the main cause of death among farmers and farm workers; most common falls happen when descending or climbing a tree or vehicle. Especially, falling from trees in the agricultural areas due to climbling the trees to harvest yields is another form of falling from heights.,, Falling from a tree can result in main visceral, disabling spinal, and complex facial injuries. In the USA in 2017, falls to the lower level estimated for 887 deaths in the private industry and 28 deaths in the section of agriculture. Fall from the tree is one of the most common types of injuries in Iran and leads to a great number of admissions to health centers and hospitals. Hence, during September until October 2017, a total of 52 injured cases due to falling from walnut trees in Tuyserkan County were reported.
The walnut trees are cultivated in rural areas of Iran. Tuyserkan is one of the natural places of walnut trees in worldwide. Walnut production has the most role in the economy of Tuyserkan with an overall zone of about 5100 ha which even lies in the first area in Iran. However, the methods of harvesting walnuts in Tuyserkan are still traditional and nontechnical method, and gardeners climb the trees and harvest walnuts. This action imposed them at risk of falling trees. Falls frequently occur in the agriculture segment because no protections are taken or any equipment that is used is flawed, not suitable, or used wrongly.
Studies indicate that unsafe working conditions and workers' behavior are effective in fall and injuries in the workplace. Protective methods are not commonly used by farmers and farm workers. The use of personal protective devices and engaging in protective behaviors by farmers depend on a diversity of factors. Factors including knowledge and attitude about risks and right use of protective measures, reinforcing factors and enabling factors about preventive behaviors and measures. Identifying the effective factors in using protective measures is necessary to any interventional plan. Nevertheless, studies considering the role of an extensive series of factors based on a definite framework are restricted. Selecting the model of health education is the first step in identifying the various effective factors.
The PRECEDE framework was developed and introduced to find behavioral, designing, planning, and evaluation problems of health. The study by Rezapur-Shahkolai et al. indicated that the PRECEDE model can be useful in determining the predictive causes of injuries. In the world, there are no enough data in identifying the various effective factors of falls from height in the agricultural sector. Data about reasons type or other specific features of falling from height incidents are unknown. Besides, there are no studies in this area, especially addressing falling from height in farmers and farm workers. Because of the unavailability of the agricultural databank and lack of researches concerning reasons and factors of fall-related injuries, taking preventive PRECEDE measures to reduce the potential risk of injuries is difficult.
Thus, in this study, we used the model to recognize causes and factors that can be related to the acceptance of the protective measures for prevention farmers and farm workers from falling from the walnut tree.
| Methods|| |
This cross-sectional study was conducted in Tuyserkan County, placed in the Hamadan province (west of Iran), from July 1, 2018, to November 30, 2018. Tuyserkan County with a harvest level of 54,000 ha is an important county of walnuts production in Iran.
According to the values derived from Darçin and Darçin, and considering the 95% confidence level and a precision of 2%, the overall required sample size was obtained as 240 farmers and farm workers.
The inclusion criteria were farmers and farm workers residing in one of these villages and having a history of climbing from the walnut trees. The farmers and farm workers who changed their living location or who had not experienced the climb of walnut trees and farmers and farm workers not willing to participate in this research were considered as exclusion criteria. Multistage sampling method (stratified-cluster-random) was used for this purpose so that first Tuyserkan county was divided into five districts based on the distribution of walnut orchards (Tuyserkan city and Sarabi orchards, Sarkan orchards, orchards of the villages located in the central part of the county, orchards of Khorramrud district, and orchards of Qhelqhelrud district). A sample size of 50 people is considered for each district. Then, two villages were selected from each district in rural areas using the cluster sampling method and the sample size assigned to each village was based on random sampling among gardeners whose names were already provided to the team by the village council or village mayor. In connection with the city of Tuyserkan, the city was divided into four districts: Sarabi, Ainabad and its suburbs, Mir Razi al-Din and its suburbs, and Ghale-ghazi and its suburbs, and a sample size of 10 people was allocated to each part. Samples were randomly selected from these areas.
We gathered data in cooperation with community health workers in health houses from 12 villages. Data were gathered by face-to-face interviews with certain farmers and farm workers. Interviews were conducted in the health houses of villages. The questionnaire was developed according to the review of literature.,,, We measured the predisposing factor (knowledge), predisposing factor (attitude), enabling factors, reinforcing factors, protective measures, and demographic data through a self-reported questionnaire. To collect the data, five expert health workers held interviews with individuals.
Data collection instruments
We collected data on key factors influencing the protective measures to fall from the walnut tree by farmers and farm workers using the PRECEDE model. The study involved a questionnaire that involved three sections. The study involved questions about demographics, injured farmers, history of injuries, and PRECEDE model constructs including predisposing factors (knowledge) about protective measures (10 items), predisposing factors (attitude) about protective measures (10 items), enabling factors to approve protective actions (3 items), reinforcing factors to approve protective actions (2 items), and protective measures for reducing fall of the walnut tree (12 items).
Validity and reliability
The primitive version of the questions was developed by investigators. Afterward, to measure content validity and face validity, the questions of the questionnaire were appraised by ten specialists in occupational health and health education. At first, the content validity ratio was considered by specialists' judgment and items with the score ≤0.62 kept on in the questionnaire. Then, the content validity index was considered by researchers. The score of 0.79 was measured as the minimum appropriate content validity index. In addition, the face validity of questions was testified by eight farmers and farm workers. so that the questions were recited for them, and we considered the level of difficult questions.
To estimate the reliability, Cronbach's alpha was used. Cronbach's alpha was assessed although directing a pilot study on 30 farmers and farm workers. The Cronbach's alpha for reliability was above 0.76 for all constructs. The validity and reliability step recommended minor changes to the questionnaire before finalization.
SPSS 24, IBM, Armonk, NY, United States of America) and the partial least squares (SmartPLS GmbH P.O. Box 1123 D-25474 Bönningstedt Germany) approach were applied to examine the reliability of the measures. Furthermore, data were recorded in SPSS (version 24) and were analyzed using Chi-square. We directed the confirmatory factor analysis to review homogeneity (factor loading and t-value), reliability (composite reliability and Cronbach's alpha), and convergent validity (average variance extracted [AVE]) of the latent variable indicators. In the study, the t-value was more than ±1.96 and factor loading measurements of ≥0.6 were approved. The composite reliability score was ≥0.81 and Cronbach's alpha value was 0.72 and above for each construct. In addition, the results of the AVE test show that the score constructs were ≥0.51. Therefore, any items of the construct were not removed from the model. At last, after the model was found to meet the criteria for the measurement model, the structural models were confirmed [Table 1].
After clarifying the purpose of the study, clearly, and confidentiality of information for farmers and farm workers, all of them participated in the study voluntarily. Verbal informed consent was obtained from them. This study was approved by the Ethical Committee of Hamadan University of Medical Sciences (No.: IR.UMSHA.REC.1397.266).
| Results|| |
The study response rates were 92.5%, and the information of 7.5% did not include in the analysis due to failure to answer the questions. Demographic features of the farmers and farm workers are indicated in [Table 2].

Farmers' protective measures were inadequate as follows
Avoiding go out of the walnut tree during fatigue and decentralization (43.2%), avoiding go out of the walnut tree when the wind starts (49.5%), and avoid of going out of the walnut tree during the bad physical condition (52.3%) were the most frequent protective behaviors (PBs). There were no significant differences between the protective measures of participants and their demographic characteristics (P > 0.05) (data not shown).
[Figure 1] shows the conceptual framework of PRECEDE model used in the study.
We experienced all paths proposed by the PRECEDE model. According to the suggested paths by the PRECEDE model, predisposing factors (β =0.348, t = 5.116), enabling factors (β =0.131, t = 3.672), and reinforcing factors (β =0.164, t = 2.128) had a positive impact on protective measures, with an explained variance of 35.3%. In this study, the goodness-of-fit value was obtained as 0.455, showing an excellent overall fit of the model to the data. The predictive validity (Q2) value for protective measures was 0.320. These values confirm that the PRECEDE model has the power to forecast the variations in protective measure constructs [Table 4].

| Discussion|| |
This current study developed a research model that was to enrich our understanding of the effective factors on protective measures among farmers and farmworkers. The study results show that a significant amount of variance in the proposed model's dependent constructs was explained by the model's independent constructs. There is a lack of data supporting the role of a number of surveyed structures in agricultural health and injuries studies.
Our research is one of the few theoretical framework studies considering farmers' protective measures. Our findings showed that the implementation of protective measures by the farmers and farm workers is poor. This result is in line with the results of Singh and Gupta and Zveglich et al., indicating that most fall injuries occur in conditions where prevention practices are not done. Farmers do not use protective equipment for various reasons. These reasons included unattractiveness of protective measures, perceived fewer hazards, knowledge and attitude fewer about hazards, cumbersome protective measures, and slowing down work by farmers. In addition, in this study, farmers and farm workers believed that the use of protective measures for the prevention of fall from the walnut tree is not hard. The above reasons point out the need to incorporate farmers' safety preferences in interventional programs that are designed to promote protective measures for fall prevention from the walnut tree among farmers and farm workers.
Our study showed that knowledge and attitude have a positive influence on protective measures so that the knowledge and attitude of the farmer are effective in taking protective measures in farmers and agricultural workers. Consistent with another study, the results confirmed that a rise in knowledge and attitude enhanced safety behaviors. Contrary to our results, the results of the Derafshi et al.'s study showed the lack of significant relationship between knowledge and attitude and use of personal protective equipment. Usually, the support of public health prevention, work on the hypothesis that poor knowledge and attitude result in protective measures that cause injuries. By increasing their knowledge and proper attitudes, they will involve in safer behaviors.
We also found that the enabling factors were associated with protective measures, which was consistent with the results suggested in previous studies., Enabling factors are those internal and external conditions directly related to the issue that helps people accept and continue healthy or unhealthy behaviors or to embrace or discard specific environmental conditions. Based on previous studies, several of these factors include the resource, and safety education and experience are the most usually cited enabling factors to protective measures. Maybe, these factors make an item to carry out.
Findings supported that the reinforcing factors are effective on the protective measures. These results are consistent with the results of the previous study. Reinforcing factors are the individual and community attitudes that support or make it difficult to adopt healthy behaviors or fostering healthy environmental conditions. Probably, farmers who have experienced the social pressure of others indicated the heightened concern about the health effects of fall and were more likely to do behaviors.
The results of this study should be considered in light of its limitations. First, the findings of the study might be affected via self-report bias. Second, this study was directed in a restricted zone, and therefore, caution should be exercised regarding its generalizability.
| Conclusions|| |
The findings of this research recognized the causes of farmers' and farm workers' protective measures. In addition, farmers' and farmworkers' protective measures to prevent falling during the walnut collection period were inadequate. Considering the direct effect of the PRECEDE model component on protective measures, it seems that the PRECEDE model could serve as a guide to developing a more effective intervention for safety measures of Iranian farm workers and farmers. According to the study, the results suggested that safety education among farmers could raise awareness and attitude of falling during the walnut collection risk and the adverse health consequences. Therefore, there is a critical need to educate and create knowledge regarding the use of protective measures. Hence, must training programs to focus on safety education. Further, policy and regulations on safety should be made stringent in Iran.
