Introduction Primary healthcare practitioners (PHCPs) can contribute to the control of cancer by promoting healthy lifestyles to patients. Given the scarcity of data in the Middle East on this subject, we sought to determine, through a cross-sectional survey, the status of healthy lifestyle promotion by PHCPs (physicians, nurses, midwives, nurse aids) in Jordan.
Methods Building on published studies, an Arabic questionnaire was developed to measure knowledge, perceptions and practices of Jordanian PHCPs with regard to healthy lifestyle counselling. A purposive sample of 20 clinics covering the main regions of Jordan was selected and all PHCPs were asked to complete the questionnaire.
Results 322 practitioners (32.3% physicians) responded (a 75.1% response rate). 24.4% of PHCPs were current cigarette smokers (physicians 44.2%). Roughly 58% of physicians and 50% of non-physicians reported advising the majority of patients to quit tobacco, but proportions were lower for providing other services (eg, asking about frequency of tobacco use, inquiring about diet and exercise, providing evidence-based guidance on quitting tobacco or improving diet and activity). Only 8% of the sample reported collectively asking the majority of patients about smoking status, exercise and diet; and providing evidence-based tips to improve these. Among physicians and non-physicians, 14.2% and 40.4% were able to identify the lifestyle-related risk factors associated with breast, colorectal and lung cancer. In multivariable analyses, confidence was the only significant variable associated with provision of counselling on healthy lifestyles.
Conclusions Among Jordanian PHCPs, primary prevention services are underprovided, and data suggest ample room to improve PHCPs' skills and practices.

Strengths and limitations of this study
To the best of our knowledge, no other study has been publicly availed with regard to the level of preparedness of primary healthcare practitioners in Jordan to provide cancer prevention counselling to patients.
The employed survey covered several lifestyle-related counselling practices rather than focusing on one only, under the premise that any primary healthcare practitioner should be well versed with all lifestyle-related factors.
The study covered primary healthcare clinics from across the country in Jordan.
The study was cross-sectional in nature and not powered to conduct in-depth stratified analyses.
Possible factors influencing the provision of healthy lifestyle-related services are numerous, and an in-depth analysis of these factors was beyond the scope of the analysis.
The growing burden of non-communicable disease (NCD) is a challenge being faced by most countries and has moved leading health organisations to reiterate the importance of disease prevention through healthy lifestyles.1 ,2 Cancer in particular, owing to the dramatic health and economic toll it exerts on afflicted patients, necessitates serious efforts to promote lifestyles that lower the risk of this NCD.3 ,4 One recommended strategy is through healthy lifestyle promotion (to patients) by healthcare practitioners.2 ,5 Primary healthcare practitioners (PHCPs) in particular are acknowledged to be an effective tool for healthy lifestyle promotion,6–9 and are in a key position to play a highly valuable role in cancer prevention.4 ,10 Despite the clear importance of PHCPs engaging in NCD prevention, they face barriers and have yet to realise their full potential in delivering such basic and essential services.11 ,12
In the Middle East, countries struggle to address the rising NCD and cancer burden amid environments of resource constraints and political unrest.13 ,14 A country with a largely young population, Jordan faces further challenges in the advent of its population ageing.15 To add to these challenges, Jordan's lay public appears to be regressing with regard to lifestyle: tobacco use is increasing (with most recent estimates being 32.3%),16 and only 27% of the population reports being physically active.17 It is thus not surprising that the three most commonly occurring cancers in the country, breast, colorectal and lung,18 are associated at least in part with unhealthy lifestyle practices. Mounting evidence also indicates that the public in Jordan are underinformed with regard to cancer prevention and risks.17 ,19–21 However, if the public is to become better informed, healthcare providers must also be at the forefront to address this matter: the majority of the public prefers to obtain its cancer knowledge through healthcare providers (rather than other information-seeking channels).17
Models have been put forth with regard to what healthy lifestyle counselling should entail,5 and studies have explored the viability of NCD prevention through PHCPs.12 However, there are limited data specific to the region's PHCPs. We sought to study a Middle Eastern healthcare system that represents a country and region which faces various challenges that are likely to hinder the provision of NCD and cancer prevention services. Specifically, we sought to assess practices and perceptions among PHCPs in Jordan's largest public healthcare (Ministry of Health) clinics with regard to cancer prevention through healthy lifestyle counselling, thereby providing much-needed insight to inform interventions that promote cancer (and other NCDs) prevention. In addition, research generated in Jordan can also be useful for other neighbouring countries with similar sociopolitical challenges.
Setting and sample
A purposive sample of clinics representing the different types of public primary healthcare clinics in Jordan and covering the three main regions of the country (North, Central, South) was selected by the Jordanian Ministry of Health. Throughout February and March of 2014, all active PHCPs (ie, physicians, nurses, midwives and nurse aids) in each clinic visited were asked to complete the questionnaire.
The self-administered Arabic questionnaire was developed using the social cognitive theory as a guiding framework.22 Other studies which evaluated professional practices in the area of healthy lifestyle counselling and cancer screening also were reviewed.23–29 However, a substantial part of the final tested questionnaire was customised to the local primary healthcare environment, covering key practices that were feasible and of relevance to promote among Jordanian PHCPs.
Content validity for the questionnaire was ensured by reviewing it with physicians and allied health staff working in the Jordanian Ministry of Health as well as the King Hussein Cancer Center; and the tool was piloted in one primary healthcare clinic. Cronbach’s α (internal consistency) of the questionnaire was 0.80.
The final questionnaire consisted of two main components: provider-reported knowledge, attitudes and practices pertaining to cancer-related healthy lifestyle counselling (tobacco use, healthy diet, physical activity); and provider-reported knowledge, attitudes and practices pertaining to counselling on the perceived burden and early signs and symptoms of the most prevalent cancers in Jordan: breast, colorectal and lung cancers. The latter component is beyond the scope of the current analysis, and descriptions of the sections covering only the former component are therefore included below.
Practices: we measured the extent to which various actions (asking about each lifestyle factor, explaining the factor's association with cancer, and providing evidence-based recommendations on how to improve or perform each factor) were performed for adults visiting the clinic. Specific lifestyle factors included healthy diet, physical activity, obesity and smoking. Practitioners were asked to estimate the percentage of patients aged 18 years or older on whom the actions were performed in the past 2 months. Responses to these variables were further categorised during analysis (whether or not each activity was performed for the majority—70% or more—of adult patients seen). Given our interest in ultimately promoting the provision of healthy lifestyle counselling to the majority of patients in a comprehensive manner (ie, encompassing smoking, diet, physical activity and obesity), we also defined a compound variable of overall provision of healthy lifestyle counselling by observing the proportion of practitioners who reported asking about smoking status, exercise status and diet; and providing evidence-based tips to improve these in 70% or more of patients.
Level of agreement (on a five-point scale) with statements covering the provision of healthy lifestyle counselling: the questionnaire specifically gauged the perceived value of healthy lifestyle counselling, negative and positive outcomes of such counselling; need for counselling; perceived professional responsibility to provide counselling; and the need for training in this area. Responses to these variables were further categorised during analysis (for each attitudinal statement, whether or not respondents had an unfavourable perception that could deter from the provision of healthy lifestyle counselling).
Perceived confidence (on a five-point scale) to ask about each lifestyle factor, explain the factor's association with cancer, and provide evidence-based recommendations on how to improve or perform each factor: responses to these variables were dichotomised during analysis (confident or highly confident vs all other responses). A dummy variable also was created to reflect whether or not practitioners concurrently reported confidence to provide several activities.
A general section probing barriers to counselling patients on cancer prevention and early detection was included. Various factors (practitioner-related; patient-related; system-related) were listed and practitioners rated each according to the level of significance (major barrier; moderate barrier; not a barrier).
Knowledge with regard to the effect of lifestyle factors on the risk of incidence of breast, colorectal and lung cancers (increases risk, decreases risk, no effect, don't know). A dummy variable was also created to reflect on whether or not practitioners were able to concurrently identify lifestyle-related risk factors associated with each of the three cancer sites probed.
A section measuring practitioners' demographic and professional characteristics.
Descriptive statistics were generated to present the characteristics of the sample and the attitudes, practices and knowledge levels of practitioners with regard to various elements of cancer prevention through healthy lifestyle counselling. Descriptive statistics were further analysed in a bivariate manner for physicians and non-physicians, since this particular factor was of practical relevance in informing recommendations for future training efforts (ie, whether or not they may need to be tailored to the profession).
All analyses were performed using STATA SE V.12.1.
Multivariate logistic regressions were run to assess the possible demographic, professional, attitudinal and knowledge factors that were associated with providing specific actions (eg, asking about and providing evidence-based recommendations for healthy eating; asking about and providing evidence-based recommendations for exercise; and asking about providing evidence-based recommendations to stop smoking). Independent variables explored in the models included gender, age, being a physician, whether or not the respondent engaged in a healthy lifestyle (exercised regularly during the week, ate fruits and legumes regularly during the week, did not eat red meat or fast foods frequently during the week), whether or not the respondent valued healthy lifestyle counselling, knowledge of the lifestyle factor's effect on risk of cancer, and confidence in providing the action.
A total of 322 practitioners (218 nurses, midwives and nurse aids; 104 physicians) across 20 clinics in the North (8 clinics), Central (9 clinics) and South (3 clinics) regions of Jordan responded to the survey, resulting in a 75.1% response rate (the response rate was calculated as a percentage of the number of respondents divided by the number of practising physicians and nurses in the clinics). The sample had a larger proportion of non-physicians and women than physicians and men, respectively (table 1).
With regard to lifestyle practices, 24.4% of the sample were current cigarette smokers (with physicians, who were largely male, having a smoking rate of 44.2%); 14.8% were current waterpipe smokers. Unhealthy lifestyle practices were decipherable, most noticeably the low reported rates of regular physical activity.
Reported frequencies of various activities related to counselling on healthy lifestyles are included in figure 1. The most frequently reported activity was advising tobacco users to quit: ∼58% of physicians and 50% of non-physician PHCPs reported doing this with the majority of their patients. However, less than half of the practitioners reported providing to the majority of their adult patients other key services such as asking about the frequency of tobacco use, inquiring about dietary and exercise habits, and providing patients with evidence-based guidance with regard to quitting tobacco and improving their diet and physical activity. When the concurrent provision of practices was observed, rates of provision dropped further: roughly 8% of the sample reported asking about smoking status, exercise status and diet; and providing evidence-based tips to improve these in the majority of patients.
Table 2 lists various statements which practitioners were asked to express their level of agreement with, and the proportions of respondents with perceptions that may deter from provision of healthy lifestyle counselling. With the exception of a few statements, results were comparable between physicians and non-physicians. A substantial (61.7%) proportion of practitioners felt that patients were sufficiently knowledgeable (and not in need of education) with regard to smoking's association with cancer, while ∼41% and 38% felt similarly with regard to patient's knowledge and need of education on the diet–cancer and physical activity–cancer association (respectively). With regard to outcome expectancies, 45.5% of practitioners did not perceive that their smoking cessation advice would increase the likelihood of a patient quitting, while roughly 37% and 30% did not perceive that their advice would influence the likelihood of patients improving their exercise habits or dietary ones, respectively. Furthermore, 40.5% of respondents did not reject the statement that lifestyle counselling would bother patients, and 36.5% were unable to reject the statement that counselling made them feel uncomfortable. In addition, 61.6% of practitioners did not reject the suggestion that ‘counselling on prevention of other non-communicable diseases is more important than counselling on cancer prevention’. Finally, variability was observed with regard to which PHCP (nurse or physician) should be responsible for healthy lifestyle counselling.
When probed with regard to confidence (table 3), lower proportions of non-physicians tended to report being confident across the healthy lifestyle counselling tasks listed. Relatively low proportions (not exceeding 55%) of all practitioners reported high confidence in documentation of tobacco use and frequency; and relatively lower proportions of practitioners reported confidence in explaining the effects of specific lifestyle factors such as obesity and diet on the risk of cancer.
When analysing knowledge of lifestyle factors and whether or not they influenced the risk of breast, colorectal and lung cancers, high levels of knowledge were observed with roughly no <70% of practitioners identifying individual risk factors per cancer site appropriately (with the exception of red meat and high fibre diet and colorectal cancer risk: low levels of knowledge with regard to these factors were driven by the substantially lower proportion of non-physicians who did not know of the association of these dietary staples with cancer). When a compound variable reflecting whether or not practitioners were able to identify lifestyle-related risk factors associated with each of the three cancer sites probed, lower proportions of practitioners could do so (14.2% of non-physicians and 40.4% of physicians).
The most frequently reported barriers to the provision of healthy lifestyle counselling were largely patient related. These included ‘patients do not want to quit smoking’, ‘low literacy of patients’, ‘patients do not want to make dietary changes’, ‘patients scared or bothered if cancer is discussed’ and ‘patients cannot access healthy food’.
Multivariable logistic regression analyses were conducted to assess the association of various factors with the provision of healthy lifestyle counselling. Across models run to predict correlates of asking about and providing evidence-based recommendations on healthy lifestyle factors, confidence was the only significant independent variable. For example, those reporting confidence in asking about and providing recommendations for a healthy lifestyle (healthy diet, exercise and smoking cessation) were 30% more likely to engage in these activities than those who did not report such confidence. Those reporting confidence in asking about smoking status, advising quitting and providing recommendations for quitting were roughly twice as likely to engage in these activities than those who did not.
Equipped and knowledgeable PHCPs can be a key and cost-effective resource for counselling on and contributing to the prevention of cancer and other NCDs. Despite this long-standing fact, the findings of our study confirm, in governmental primary care clinics in Jordan, the underprovision of various activities related to healthy lifestyle counselling; and the existence of knowledge gaps and misperceptions that can deter from such counselling within the primary healthcare setting. Our findings, based on a sample of clinics representing the three main geographic areas of the country, shed light on an understudied practitioner population existing in a developing region (and serving a significant segment of the country's host population as well as incoming refugees from surrounding areas). Thus, the findings can provide the impetus to avail of and inform interventions to improve practitioner perceptions, knowledge and practices in this area of the world.
With regard to the current status of healthy lifestyle counselling, there was an underprovision of various important aspects of healthy lifestyle counselling. Only advising cigarette smokers to quit was estimated to have been provided to roughly half of the patients seen. When we combined counselling activities, as exemplified by the proportion of practitioners who reported asking about smoking status, exercise status and diet, and providing evidence-based tips to improve these in the majority of patients, it was evident that there was a dramatic underprovision of comprehensive lifestyle counselling. Relatedly, individual traits existed which could negatively influence the likelihood that PHCPs would engage in healthy lifestyle counselling. Our sample of PHCPs generally did not engage in regular physical activity, did not (in high proportions) follow a healthy diet and a substantial proportion of physicians (44.2%) were cigarette smokers.
With regard to perceptions, many practitioners believed that patients already knew enough about lifestyle factors such as smoking and did not need further counselling. Furthermore, patient-stemming barriers (as a result of patient attitudes, illiteracy) were the most frequently cited impediments to the provision of counselling. Many of the practitioners in our sample also did not perceive that their counselling would increase the likelihood that a patient changes their behaviour. Finally, while knowledge about individual lifestyle factors and their association with cancer was generally high, knowledge levels were substantially lower when examining indicators of comprehensive (in the context of the lifestyle factors and cancers we probed) knowledge.
The determinants of healthy lifestyle counselling by practitioners vary in the literature and include, at the level of the practitioner, age, gender, specialty, extent of training, identifying a lifestyle-related risk factor in a patient, practising the health habit counselled on, reporting confidence to counsel and perceiving value in the practice.23 ,29–32 Our multivariable analyses only revealed self-efficacy as a consistent significant predictor of provision of healthy lifestyle counselling. Self-efficacy, however, is multifaceted, playing an intricate role in determining health behaviour both by directly influencing that behaviour, and by influencing (and being influenced by) various attitudes and individual characteristics that also influence the performance of the behaviour.22 Our results provide some insight into factors that most likely influence self-efficacy, and thus provide various discussion and educational points for inclusion in interventions (such as training) that can improve the self-efficacy of PHCPs to provide healthy lifestyle counselling. Differences among physicians and non-physicians that we detected in some results also emphasise the need to address—in any potential intervention—each professional category in a customised manner.
The possible factors influencing the provision of healthy lifestyle-related services are numerous and span multiple levels and individuals.12 ,33 ,34 Although we could not cover the full scope of these factors, our findings can contribute data and insight to inform the planning of interventions to improve healthy lifestyle counselling through PHCPs in Jordan.
Our study has its limitations. Our survey was a descriptive cross-sectional one and relied on the use of a tool that had not been previously validated (we designed the tool for the specific purpose of the study). Although our results indicate that the tool was reliable, our findings should be interpreted with this in mind. In addition, we were not able to verify practitioner-reported results with objective measures. The documentation systems in the clinics we targeted are underdeveloped, and we were also unable to conduct patient interviews to verify our findings. Nevertheless, given that our results indicate substantial practice and knowledge gaps—particularly when gauging whether or not providers availed several actions collectively, or could identify all the relevant risk factors for the cancers evaluated—it is unlikely that our findings or conclusions would have differed in direction had we supplemented our data with more objective measures. Furthermore, although we highlight the strong association of reported confidence with providing counselling on cancer prevention through healthy lifestyles, our intention was not to identify causal factors but rather to offer practical information that can be used in future efforts to educate healthcare professionals in this sector. Confidence is likely to have been shaped by other inter-related factors such as skills, knowledge and perceptions with regard to the value of counselling. Determining these intricate connections was beyond the scope of our study. We also did not include primary healthcare clinics in the Royal Medical Services sector (a subsidised public healthcare system that was built to serve army officers and their beneficiaries and subsequently grew to provide care to non-veterans who are willing to pay for such services). However, the Ministry of Health's primary healthcare clinics in Jordan are the largest primary care services in the country, are accessible to all Jordanians and are accessed by more than half of the population.35 ,36 Finally, with regard to limitations, we were constrained with a purposive sample of 20 clinics. The Jordanian Ministry of Health nominated a purposive sample that it deemed representative of its clinics across the country. Owing to time constraints that practitioners in this sector typically face, the Ministry of Health restricted its selection to these 20 clinics. Having said that, we conducted post hoc power analyses to ensure that our study was sufficiently powered to detect various estimates.
Despite our limitations, we were able to study a sample of clinics that covered the main governorates in the country and benefited from a relatively high response rate. Our findings indicate that, among Jordanian PHCPs in governmental healthcare clinics, primary cancer prevention services through healthy lifestyle counselling are underprovided. Our data also suggest that there is ample room for improving PHCPs' skills and practices.
