Mortality patterns of Australian male farmers and farm managers

Health check-ups for the French under-consuming agricultural population: A pilot evaluation of the Instants santé MSA program

BACKGROUND

The social protection scheme in charge of farmers and agricultural employees (MSA) in France has developed a two-step health promotion program with a nurse appointment followed by a consultation with a doctor of the participant's choosing to reach its under-consuming beneficiaries and enroll them back into a care pathway. Our objective was to carry out a pilot evaluation of this program.

METHODS

The evaluation was carried out on the population invited during the second semester of 2017 using data from the program's service providers (date of invitation, of nurse appointment…), regional MSA bodies (consultation voucher), and reimbursement data (other care consumption). Participation rates were calculated overall and by participant characteristics. Medical needs were identified during the nurse appointment and new care pathways were assessed using reimbursement data. Multivariable regression models identified factors associated with participation.

RESULTS

2366 beneficiaries were included in the analysis. 1559 (65.89%) were men and mean age was 52.41 (standard deviation = 14.86). 409 (17.29%) attended the nurse appointment. There was a significant increase in participation with age, in farmers vs. employees (odds ratio = 1.905, 95% confidence interval = 1.393-2.604), and in people living in the most disadvantaged areas (odds ratio = 1.579, 95% confidence interval=1.079-2.312). Participation to the consultation following the nurse appointment was high (62.35%-73.11%). 87.53% of participants had at least one medical need, and new care pathways were more frequent among those who had attended the nurse appointment (55.50% vs. 34.80%, p < 0.0001).

CONCLUSIONS

This pilot evaluation shows promising results which need to be confirmed with a national evaluation of the program and longer-term evidence.

"We're Lucky to Have Doctors at All"; A Qualitative Exploration of Australian Farmers' Barriers and Facilitators to Health-Related Help-Seeking

This study aimed to explore barriers and facilitators that impact on farmers' help-seeking behaviours for health and mental health concerns. Fifteen semi-structured interviews were conducted with farmers (12 male; age 51.7 ± 12.6 years) from three rural regions in South Australia. Interviews explored demographic and farm-related characteristics, perceptions of individual (and where relevant family) health and mental health concerns and experiences, and perceived barriers of health support-seeking. Thematic analysis was used to identify key themes. Four key themes were identified relating to help-seeking; personal attitudes and beliefs, farm-related barriers, health system barriers and the provision of support from family and friends. Dominant personal attitudes included valuing independence, strength and privacy. Farm related barriers included the 'farm comes first' and the fact that 'farm work is never done'. Health system barriers included issues relating to availability of choice and access, professionals (lack of) understanding of farm life, and time and financial costs of accessing care. Provision of support from family and friends involved informal help and advice, including facilitating access to professional support. Multiple attitudinal, structural, and farm-related issues affect farmers' help-seeking. Professionals who understand farm work practices and routines are valued by farmers and this is likely to facilitate access to care. Workforce development programs and community programs that involve farmers' perspectives as consumers and co-designers, using evidence-based strategies, may assist in strengthening these relationships.

"She'll Be Right, Mate": A Mixed Methods Analysis of Skin Cancer Prevention Practices among Australian Farmers-An At-Risk Group

This study examined Australian farmers’ engagement with skin cancer prevention behaviours and explored what made it hard for them to be ‘SunSmart’ (barriers), and what could be done to make prevention easier (facilitators). In total, 498 farmers (83.1% male, 22–89 years, 50.8% grain, sheep, or cattle farmers) participated. The least frequently performed SunSmart behaviours (reported as never practiced during summer) were using SPF 30+ sunscreen (16.6%), wearing protective sunglasses (10.5%), and wearing protective clothing (8.6%). Greater engagement (i.e., higher scores on scale from Never to Always) with SunSmart behaviours was explained by gender (female), educational attainment (trade or technical college certificate vs. high school), personal skin cancer history, and skin sun sensitivity. Barriers reported by farmers related to personal preferences (e.g., short-sleeved rather than long-sleeved clothing), comfort, and perceived impracticality of sun protection. Farmers’ solutions included making protective clothing and sunscreen more appropriate for farm work (e.g., by making clothing more breathable). A personal health scare was the most reported motivation for skin cancer prevention. Findings highlight the need for increased access to sun-protective clothing and sunscreen that is suitable for wearing when working on farms, complemented by culturally appropriate health education messaging, to encourage more farmers to perform SunSmart behaviours.

Association between pesticide exposure and colorectal cancer risk and incidence: A systematic review

BACKGROUND

Studies investigating the association between pesticide exposure and colorectal cancer (CRC) risk have been inconclusive.

OBJECTIVES

Investigate the association between pesticide exposure and CRC risk through a systematic literature review.

METHODS

CRC has the fourth-highest rate of cancer-caused death in the US after lung cancer, breast cancer in women, and prostate cancer in men. Here we have conducted a systematic literature search on studies examining the association between any pesticide exposure and CRC risk using PubMed, MEDLINE via EBSCO host, and Embase according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist.

RESULTS

Following the review, 139 articles were included for qualitative evaluation. Study participants were farmers, pesticide applicators, pesticide manufacturers, spouses of pesticide applicators, farm residents, Korean veterans of the Vietnam War, rural communities, and those who consumed food with pesticide residues. The studies' results were split between those with significant positive (39 significant results) and inverse (41 significant results) associations when comparing pesticide exposure and CRC risk.

DISCUSSION

From our literature review, we have identified a similar number of significant positive and inverse associations of pesticide exposure with CRC risk and therefore cannot conclude whether pesticide exposure has a positive or inverse association with CRC risk overall. However, certain pesticides such as terbufos, dicamba, trifluralin, S-ethyl dipropylthiocarbamate (EPTC), imazethapyr, chlorpyrifos, carbaryl, pendimethalin, and acetochlor are of great concern not only for their associated elevated risk of CRC, but also for the current legal usage in the United States (US). Aldicarb and dieldrin are of moderate concern for the positive associations with CRC risk, and also for the illegal usage or the detection on imported food products even though they have been banned in the US. Pesticides can linger in the soil, water, and air for weeks to years and, therefore, can lead to exposure to farmers, manufacturing workers, and those living in rural communities near these farms and factories. Approximately 60 million people in the US live in rural areas and all of the CRC mortality hotspots are within the rural communities. The CRC mortality rate is still increasing in the rural regions despite the overall decreasing of incidence and mortality of CRC elsewhere. Therefore, the results from this study on the relationship between pesticide exposure and CRC risk will help us to understand CRC health disparities.

Sun safety knowledge, practices and attitudes in rural Australian farmers: a cross-sectional study in Western New South Wales

Background

Rates of skin cancer in Australia are amongst the highest in the world, with Western New South Wales (NSW) exhibiting very high prevalence. There is a large proportion of outdoor workers, including farmers, in Western NSW who have high levels of sun exposure and hence are at greater risk of developing skin cancer.

Aims

To characterise the current sun safety practices of farmers in Western NSW and explore their knowledge, attitudes and perceived barriers towards sun safety and its implementation.

Methods

A cross-sectional survey study was conducted using a self-directed questionnaire. Participants were recruited at field days held in Western NSW and through surveys distributed at general practices, local stores and online. Eligibility criteria were aged 18 years and over and currently working on a farm in the study region.

Results

Of the 144 participants, 89 (61.8%) were male with a mean age of 49 years. Knowledge of sun safety was relatively high with most questions answered correctly by greater than 80% of participants. Risk of developing skin cancer was underestimated in 58 (40.3%) participants. Of all participants, 89 (62.2%) identified one or more barriers to practicing sun safety. The most common barrier was forgetfulness in 62 (43.4%) participants. The identification of barriers was significantly associated with reduced engagement of sun safety practices (p = 0.009).

Conclusions

Knowledge of sun safety among farmers was high. There was, however, underestimation of risk of developing skin cancer. Addressing perceived barriers to implementing sun safety could improve sun safety practices in this cohort.

Agricultural health and medicine education-Engaging rural professionals to make a difference to farmers' lives

OBJECTIVE

Despite continued higher rates of workplace injuries, earlier morbidity and mortality and challenging climatic environments, few formal programs focus on the health, well-being and safety of farmers. The agricultural health and medicine unit, developed in 2010, was designed to increase cultural competence and empower rural professionals to improve the health, well-being and safety outcomes of farming populations in Australia. This study aimed to understand the extent to which graduates (2010-2018) use the knowledge and skills gained in their current occupations and identify barriers and enablers faced in implementing them.

DESIGN

Mixed-methods descriptive study.

SETTING

Graduates were invited to complete an online survey. Following the survey, graduates participated in a phone interview until saturation was reached.

PARTICIPANTS

Forty-one graduates completed the survey (31% response rate), and eleven interviews were conducted.

INTERVENTIONS

Education in agricultural health and medicine.

MAIN OUTCOME MEASURES

Graduates use of knowledge and skills gained from the course and the barriers and enablers they experienced in implementation.

RESULTS

The most represented occupations were nursing, medicine and agriculture (farming). Of respondents, 76% agreed their ability to diagnose, treat or prevent agricultural occupational illness or injury had improved. Positively, 42% use course content professionally at least weekly. Fifty-one per cent experienced barriers in implementing their new knowledge, and little evidence of career advancement was observed.

CONCLUSION

This study informs the continuous development of the agricultural health and medicine curriculum and highlights the importance of a collaborative and multidisciplinary approach to improving the health, well-being and safety of farming populations. Despite engaged graduates, the continued high workplace mortality, preventable non-communicable disease and challenging climatic conditions highlight the need for strategic prioritisation of farmers' health across health, agriculture and policy settings.

Occupational Risk Factors for Prostate Cancer: A Meta-analysis

Prostate cancer is the second most common cancer in men worldwide. There are many occupational factors that have been suggested to cause prostate cancer. Our aim was to evaluate the evidence for causality by a literature review of occupational factors. We searched literature in Medline and SCOPUS from 1966 to June 30, 2015 to identify occupational risk factors for prostate cancer. The following risk factors were selected: farmers/agricultural workers, pesticides - whole group, and separately organophosphate and organochlorine pesticides, carbamates and triazines, cadmium, chromium, cutting fluids, acrylonitrile, rubber manufacturing, whole body vibration, shift work, flight personnel, ionizing radiation, and occupational physical activity. For each factor a literature search was performed and presented as meta-analysis of relative risk and heterogeneity (Q and I2 index). A total of 168 original studies met the inclusion criteria with 90,688 prostate cancer cases. Significantly increased risks were observed for the following occupational exposures: pesticides (metaRR = 1.15, 95% confidence interval [CI] = 1.01-1.32; I2 = 84%), and specifically group of organochlorine pesticides (meta relative risk [metaRR] = 1.08, 95% CI = 1.03-1.14; I2 = 0%), chromium (metaRR = 1.19, 95% CI = 1.07-1.34; I2 = 31%), shift work (metaRR = 1.25, 95% CI = 1.05-1.49; I2 = 78%) and pilots (metaRR = 1.41, 95% CI = 1.02-1.94; I2 = 63%) and occupational physical activity in cohort studies (metaRR = 0.87, 95% CI = 0.81-0.94; I2 = 0%). The literature review supports a causal association for a few of the previously suggested factors.

Farm injury resulting in hospital admission: a review of farm work and non-farm work-related injury

ABSTRACT INTRODUCTIONOccupational health on farms is important because farms are not only workplaces where agriculture workers are vulnerable to high injury and fatality rates, they are also homes where families and visitors undertake a variety of activities that can result in injury. AIMTo profile and describe injuries requiring hospital admission that occurred on farms, both for injuries related to farming activities and injuries unrelated to farm work in the Midland region of New Zealand. METHODSA review of anonymised prospectively collected Midland trauma registry data from 1 July 2012 to 30 June 2018 was undertaken. Cases include unintentional injuries occurring on a farm. Non-major injuries are included to better quantify the trauma burden. RESULTSIn total, 2303 hospital admissions met the study criteria. Non-major injury accounted for 93.1% of events and 45.0% of injuries occurred during farming activities. Five people died in hospital; all injured while undertaking farm work. Males made up 84.8% of farm work and 70.9% of non-farm work injuries. Horse riding had the highest number of injuries, with off-road motorcycles, livestock, falls and quad bike injuries comprising the most common injury activities and mechanisms. Farming-related major injuries commonly involved quad bikes, non-traffic vehicles and motorcycles. Farmers in the Districts of Waitomo, Rotorua, Waipa and Taupō had the highest standardised hospitalisation rates. DISCUSSIONThe nature of farms and farming exposes people to different risks from the risks people in urban areas are exposed to. Injury prevention efforts should remain on work-related farming injuries, but also encompass the high number of injuries that are not related to farm work but happening on farms.

Long-term exposure to air pollutants from multiple sources and mortality in an industrial area: a cohort study

Background and aims

Residents near industrial areas are exposed to several toxins from various sources and the assessment of the health effects is difficult. The area of Civitavecchia (Italy) has several sources of environmental contamination with potential health effects. We evaluated the association between exposure to pollutants from multiple sources and mortality in a cohort of people living in the area.

Methods

All residents of the area in 1996 were enrolled (from municipal registers) and followed until 2013. Long-term exposures to emissions from industrial sources (PM10) and traffic (NO_x) at the residential addresses were assessed using a dispersion model. Residence close to the harbour was also considered. Cox survival analysis was conducted including a linear term for industrial PM10 and NO_x exposure and a dichotomous variable to indicate residence within 500 m of the harbour. Age, sex, calendar period, occupation and area-based socioeconomic position (SEP) were considered (HRs, 95% CI).

Results

71 362 people were enrolled (52% female, 43% low SEP) and 14 844 died during the follow-up. We found an association between industrial PM10 and mortality from non-accidental causes (HR=1.06, 95% CI 1.01 to 1.12), all cancers (HR=1.11, 95% CI 1.01 to 1.21) and cardiac diseases (HR=1.12, 95% CI 1.01 to 1.23). We also found an association between NO_x exposure from traffic and mortality from all cancers (HR=1.13, 95% CI 1.01 to 1.26) and neurological diseases (HR=1.50, 95% CI 1.01 to 2.20). Living near the harbour was associated with higher mortality from lung cancer (HR=1.31, 95% CI 1.04 to 1.66) and neurological diseases (HR=1.51, 95% CI 1.05 to 2.18).

Conclusions

Estimated exposures to different pollution sources in this area were independently associated with several mortality outcomes while adjusting for occupation and socioeconomic status.

Psycho-social transition to retirement and adjustment to retired life: influence on wellbeing and mental health in retired farmers

This article investigates the relationship between psycho-social transition to retirement on the wellbeing and mental health of retired farmers through their adjustment to retired life. The sample was taken from the Approche Multidisciplinaire Intégrée cohort, a French prospective study of retired farmers living in rural areas in south-western France. Cross-sectional analyses were conducted on a sample of 530 participants. The wellbeing and mental health of retirees were investigated through three outcomes: satisfaction with current life, perceived health and depression. Multiple mediator models show that the more retirees consider retirement as a positive event, the better they adapt to the new temporality of their retirement life and the more they feel satisfied with their current life, healthy and less depressed. Acceptance of the end of working life is also a mediator in the perceived health model. These results highlight the centrality of the adjustment to the new temporality induced by retirement. They indicate that the level of this adjustment is linked to how retirement is affectively experienced, regardless of its duration.

Comparison of cancer incidence in Australian farm residents 45 years and over, compared to rural non-farm and urban residents - a data linkage study

BACKGROUND

It is not known if the incidence of common cancers in Australian farm residents is different to rural non-farm or urban residents.

METHODS

Data from farm, rural non-farm and urban participants of the 45 and Up Study cohort in New South Wales, Australia, were linked with state cancer registry data for the years 2006-2009. Directly standardised rate ratios for cancer incidence were compared for all-cancer, prostate, breast, colorectal cancer, melanoma and non-Hodgkin Lymphoma (NHL). Proportional hazards regression was used to generate incidence hazard ratios for each cancer type adjusted for relevant confounders.

RESULTS

Farm women had a significantly lower all-cancer hazard ratio than rural non-farm women (1.14, 1.01-1.29). However, the lower all-cancer risk observed in farm men, was not significant when compared to rural non-farm and urban counterparts. The all-cancer adjusted hazard ratio for combined rural non-farm and urban groups compared to farm referents, was significant for men (1.08,1.01-1.17) and women (1.13, 1.04-1.23). Confidence intervals did not exclude unity for differences in risk for prostate, breast, colorectal or lung cancers, NHL or melanoma. Whilst non-significant, farm residents had considerably lower risk of lung cancer than other residents after controlling for smoking and other factors.

CONCLUSIONS

All-cancer risk was significantly lower in farm residents compared to combined rural non-farm and urban groups. Farm women had a significantly lower all-cancer adjusted hazard ratio than rural non-farm women. These differences appeared to be mainly due to lower lung cancer incidence in farm residents.

Farm suicides in New Zealand, 2007-2015: A review of coroners' records

OBJECTIVE

Economic recessions and severe weather events are often associated with increased suicide rates. The Global Dairy Crisis 2015/2016 led to an economic downturn in the New Zealand dairy farming industry and, coupled with droughts in some regions and floods in others, raised fears about increased suicide rates among farmers. However, little was known about suicides in the farming sector. This study reviews characteristics of recent farm-related suicides in New Zealand and assesses the extent to which financial stresses contributed to the deaths.

METHODS

Data were abstracted from coroners' records for a consecutive series of 185 people in farm- and agriculture-related occupations who died by suicide between 2007 and 2015 and for whom coronial inquiries had been completed.

RESULTS

Farm suicides were heterogeneous: six distinct risk profiles were identified. Financial stresses made negligible contributions to farm suicides. Overall, risk factors for farm suicides differed little from risk factors for suicide in the general population. However, suicide risk in farmers was exacerbated by ready access to firearms: almost 40% of farm suicides involved firearms, compared to 8% in the general population over the same time. Among farm suicides, young male farm labourers predominated, rather than farm owners or managers. For many young men, relationship losses, acute alcohol intoxication and ready access to a firearm formed a common constellation of risk factors.

CONCLUSIONS

While coroners' records are variable and do not record specific information about financial stresses and weather events, it was clear that these issues made a negligible contribution to farm suicides. A range of rural suicide prevention initiatives are needed to address various farm suicide risk profiles. In particular, young male labourers often had no contact with health services prior to death, suggesting that rural suicide prevention efforts need to be positioned within community, farming and sports organisations, as well as health and social service providers.

Chronic Disease and Health Risk Behaviors Among Rural Agricultural Workforce in Queensland

INTRODUCTION

Little is known of the lifestyle behaviors and prevalence of chronic disease in the Australian agricultural workforce. This study aimed to assess behavioral risk factors and the prevalence of chronic disease among attendees of agricultural events in rural Queensland.

METHODS

Data on lifestyle risk factors and prevalence of diabetes and cardiovascular diseases were collected from participants in four separate cross-sectional studies in rural southern Queensland. Anthropometric measures, blood pressure, serum cholesterol, and glucose levels of consenting participants were assessed by trained medical students under the supervision of rural clinicians. Data were analyzed using SPSS 22 statistical software package and t-tests and chi-square tests were used to compare differences between groups.

RESULTS

A total of 702 attendees participated; the majority were agricultural workers (n = 393). Greater psychological distress was reported among participants from these rural communities (42%) than in the Australian population (31%); however, levels of psychological distress was similar between agricultural workers and others in the sample. Fewer people in these agricultural communities reported smoking (10%), and they reported being more active (86%) than the average Australian, but a greater proportion reported high-risk alcohol consumption (53%) and were found to be hypertensive (31%). These findings were accentuated among agricultural workers.

CONCLUSION

This method of investigation both raises awareness in the community and identifies health risks for further management in a group that has otherwise been poorly defined. Resident agricultural workers have different health risks and behaviors, though psychological distress appears to be borne across these communities.

The effect of sunblock against oxidative stress in farmers: a pilot study

Farmers are frequently exposed to ultraviolet (UV) radiation which causes various diseases by inducing oxidative stress. This study aimed to assess the effects of sunblock on oxidative stress in the body. Eighty-seven farmers were divided into two groups: those who wore sunblock for five days and those who did not. The total antioxidant capacity (TAC) in urine, which is an antioxidant indicator, and 8-hydroxy-2-deoxyguanosine (8-OHdG) levels in urine, an oxidative stress indicator, were measured. The urinary TAC of sunblock users was significantly higher than that of non-users, but urinary 8-OHdG levels were not significantly different. Even after adjustment for potential confounders, urinary TAC was found to be markedly increased with sunblock usage. These results suggest that sunblock is effective in preventing oxidative stress among farmers. In addition, they show that urinary TAC can be used as a good effect marker of oxidative stress caused by UV exposure.

Translating agricultural health and medicine education across the Pacific: a United States and Australian comparison study

BACKGROUND

Populations in agricultural communities require<b> </b>health care that is interdisciplinary and cross-sectoral to address the high rate of workplace deaths, preventable injuries and illness. These rates are compounded by limited access to services and the distinctive personal values and culture of farming populations, which both health and rural practitioners must be aware of to reduce the gap between rural and urban population health outcomes. To address the unique health and medical characteristics of agricultural populations, education in agricultural medicine was established through the College of Medicine and the College of Public Health at the University of Iowa in the USA. The course was initially developed in 1974 for teaching medical students, family medicine residents and nurses, and a postgraduate curriculum was added in 2006 to develop medical/health and rural professionals' cultural competence to work in agricultural communities. This article reviews the adaptation of the US course to Australia and the educational and practice outcomes of students who completed the agricultural medicine course in either Australia or the USA.

METHODS

Data were collected from students who completed either the Agricultural Medicine: Occupational and Environmental Health for Rural Health Professionals course in the state of Iowa in the USA or the Agricultural Health and Medicine course in the state of Victoria in Australia between 2010 and 2013 (inclusive). Data were analysed using descriptive statistics, frequencies and the &#967;2 test. Students were invited to make any other comments regarding the course.

RESULTS

One hundred and ten students completed the survey (59 from the USA and 51 from Australia) with over a 50% response from both countries, indicating the high level of commitment to this discipline. Responses were consistent across both continents, with more than 91% agreeing that the course improved their abilities to diagnose, prevent and treat rural and agricultural populations. Further, both courses successfully enabled a multidisciplinary and cross-sectoral approach to agricultural health and medicine.

CONCLUSIONS

More than 72% of previous students were practising in rural and /or mixed communities at the time of the survey, demonstrating a repeatable and transferable medical education program that supports multidisciplinary care and scholarship while addressing health inequities in agricultural populations. Findings from this study indicate there are opportunities to expand globally.

The health and wellbeing of Australian farmers: a longitudinal cohort study

Background

Isolation, long work days, climate change and globalization are just some of the many pressures that make farming a vulnerable occupation for incurring mental health issues. The objective of this study was to determine whether farming in Australia is associated with poorer wellbeing, physical and mental health, and less health service use.

Methods

The Australian Rural Mental Health Study, a longitudinal cohort study was analysed over four time points comparing farmers with non-farming workers (n = 1184 at baseline). Participants were recruited from rural NSW, Australia. A number of physical, mental health, wellbeing, service use outcomes were assessed using generalised estimating equations including all waves in each model. Barriers to seeking help were also assessed.

Results

Farmers who lived remotely reported worse mental health (β −0.33, 95 % CI −0.53, −0.13) and wellbeing (β −0.21(95 % CI −0.35, −0.06) than remote non-farm workers regardless of financial hardship, rural specific factors eg drought worry, or recent adverse events. All farmers were no different to non-farming workers on physical health aspects except for chronic illnesses, where they reported fewer illnesses (OR 0.66, 95 % CI 0.44, 0.98). All farmers were half as likely to visit a general practitioner (GP) or a mental health professional in the last 12 months as compared to non-farm workers regardless of location (OR 0.59, 95 % CI 0.35, 0.97). Rural workers felt that they preferred to manage themselves rather than access help for physical health needs (50 %) or mental health needs (75 %) and there was little difference between farmers and non-farm workers in reasons for not seeking help.

Conclusions

Remoteness is a significant factor in the mental health and wellbeing of farmers, more so than financial stress, rural factors and recent adverse events. Creative programs and policies that improve access for farmers to GPs and mental health professionals should be supported.

Natural resource-based industries and prostate cancer risk in Northeastern Ontario: a case-control study

OBJECTIVE

Prostate cancer continues to be the most commonly diagnosed cancer in men, and there is limited knowledge on its preventable risk factors. A number of occupational exposures in natural resource-based industries are suspected to be related to prostate cancer risk. This study investigates associations between employment in these industries and prostate cancer.

METHODS

Data were from a population-based, case-control study previously conducted in Northeastern Ontario. Incident cases (N=760) aged 45-85 years and diagnosed with prostate cancer between 1995 and 1998 were identified from the Ontario Cancer Registry. Controls (N=1632) were recruited using telephone listings, and were frequency matched to cases by age. Lifetime occupational history was collected for all participants. Logistic regression was used to estimate ORs and their associated 95% CIs.

RESULTS

Elevated risks were observed for employment in forestry and logging industries (OR=1.87, 95% CI 1.32 to 2.73) and occupations (OR=1.71, 95% CI 1.24 to 2.35), and these risks increased with duration of employment for ≥10 years. Elevated risks were also found for employment in wood products industries (OR=1.45, 95% CI 1.07 to 1.97), and paper and allied products industries (OR=1.43, 95% CI 1.03 to 2.00), and when duration of employment was ≥10 years. There were also elevated risks in agriculture and mining-related work; however, these findings were not consistent across industry and occupation categories.

CONCLUSIONS

Prostate cancer risk may be associated with work in several natural resource industries, primarily in the forest industries. To further evaluate observed associations, studies should focus on natural resource-based exposures in larger populations with improved exposure assessment.

Farmers sun exposure, skin protection and public health campaigns: An Australian perspective

Non-melanoma skin cancer is a common and costly cancer in agricultural populations. Prevention and early detection are an effective way to decrease the burden of disease and associated costs. To examine sun exposure and skin protection practices in agricultural workers and farmers a thematic review of the literature between 1983 and 2014 was undertaken. Comparison between studies was complicated by differences in study design, definitions of skin protection, and analytic methods used. Farmers are the most exposed to harmful ultraviolet (UV) radiation of all outdoor workers and the level of reported skin protection by farmers is suboptimal. Years of public health campaigns have failed to adequately address farmers' specific needs. Increased rates of skin cancer and subsequent higher costs are expected. Estimates of sun exposure and skin protection practice indicate that protective clothing is the most promising avenue to improve on farmers' skin protection. Early detection needs to be part of public health campaigns. This review explores the quantitative data about Australian farmers and their skin protective behaviours. We investigate what the documented measurable effect of the public health campaign Slip!Slop!Slap! has had on agricultural workers and farmers and make recommendations for future focus.

Farmers’ contact with health care services prior to suicide: evidence for the role of general practitioners as an intervention point

Suicide in Australian rural communities has received significant attention from researchers, health practitioners and policymakers. Farmers and agricultural workers have been a focus of particular interest, especially in relation to levels of help seeking for mental health concerns. A less explored area, however, is the level of contact that Australian farming and agriculture workers who die by suicide have had with health providers for physical, rather than mental, health conditions. It is often assumed that farmers and agricultural workers have lower levels of contact with health care services than other rural residents, although this assumption has not been well tested. Using data from the Queensland Suicide Register, this paper describes levels of contact with health care providers in the 3 months before death by suicide among men in farming and agriculture occupations and other occupations in rural Queensland. No significant differences were found in farming and agricultural workers’ levels of contact with a general practitioner when compared with other rural men in Queensland. The current findings lend weight to the view that rural general practitioners represent an important intervention point for farming and agriculture workers at risk of suicide (whether or not those individuals exhibit accompanying psychiatric illness).

A review of prostate cancer incidence and mortality studies of farmers and non-farmers, 2002-2013

OBJECTIVES

To review the recent literature on the incidence and mortality of prostate cancer in farmers compared to non-farmers.

METHODS

Searches were conducted in seven electronic databases for observational studies published from 2002 to 2013. Studies were assessed against eligibility criteria and a narrative summary of findings presented.

RESULTS

Eighteen primary research articles were included in the review. Four of ten mortality studies and two of nine incidence studies reported statistically significant increases in prostate cancer risk in farmers. However, nearly half of all studies reported non-significant reductions in farmers' risk. Additionally, one study reported significantly increased and decreased risk using different outcome measures. Results varied considerably by geographic region, study design and degree of control for confounders, affecting comparability and strength of findings.

CONCLUSIONS

The overall evidence for increased prostate cancer risk in farmers was weak.

Radiotherapy in the Barwon South Western Region: a rural perspective

INTRODUCTION

Cancer-related mortality rates are higher in rural areas compared with urban regions. Whether there are corresponding geographical variations in radiotherapy utilisation rates (RURs) is the subject of this study.

METHODS

RURs for the regional centre of Geelong and rural areas of the Barwon South Western Region were calculated using a population-based database (2009).

RESULTS

Lower RURs were observed for rural patients compared with the Geelong region for prostate cancer (15.7% vs 25.8%, P = 0.02), rectal cancer (32.8% vs 44.7%, P = 0.11), lymphoma (9.4% vs 26.2%, P = 0.05), and all cancers overall (25.6% vs 28.9%, P = 0.06). This lower rate was significant in men (rural, 19.9%; Geelong, 28.3%; P = 0.00) but not in women (rural, 33.6%; Geelong, 29.7%; P = 0.88). Time from diagnosis to radiotherapy was not significantly different for patients from the two regions. Tumour staging within the rural and Geelong regions was not significantly different for the major tumour streams of rectal, prostate and lung cancer (P = 0.61, P = 0.79, P = 0.43, respectively). A higher proportion of tumours were unstaged or unstageable in the rural region for lung (44% vs 18%, P < 0.01) and prostate (73% vs 57%, P < 0.01) cancer.

CONCLUSION

Lower RURs were observed in our rural region. Differences found within tumour streams and in men suggest a complexity of relationships that will require further study.

Occupational differences, cardiovascular risk factors and lifestyle habits in South Eastern rural Australia

Background

In rural and remote Australia, cardiovascular mortality and morbidity rates are higher than metropolitan rates.

This study analysed cardiovascular and other chronic disease risk factors and related health behaviours by occupational status, to determine whether agricultural workers have higher cardiovascular disease (CVD) risk than other rural workers.

Methods

Cross-sectional surveys in three rural regions of South Eastern Australia (2004-2006). A stratified random sample of 1001 men and women aged 25-74 from electoral rolls were categorised by occupation into agricultural workers (men = 214, women = 79), technicians (men = 123), managers (men = 148, women = 272) and ‘home duties’ (women = 165). Data were collected from self-administered questionnaire, physical measurements and laboratory tests. Cardiovascular disease (CVD) and coronary heart disease (CHD) risk were assessed by Framingham 5 years risk calculation.

Results

Amongst men, agricultural workers had higher occupational physical activity levels, healthier more traditional diet, lower alcohol consumption, lower fasting plasma glucose, the lowest proportion of daily smokers and lower age-adjusted 5 year CVD and CHD risk scores.

Amongst women, managers were younger with higher HDL cholesterol, lower systolic blood pressure, less hypertension, lower waist circumference, less self-reported diabetes and better 5 year CVD and CHD risk scores.

Agricultural workers did not have higher cardiovascular disease risk than other occupational groups.

Conclusions

Previous studies have suggested that farmers have higher risks of cardiovascular disease but this is because the risk has been compared with non-rural populations. In this study, the comparison has been made with other rural occupations. Cardiovascular risk reduction programs are justified for all. Programs tailored only for agricultural workers are unwarranted.

Health and aging in elderly farmers: the AMI cohort

Background

The health of the agricultural population has been previously explored, particularly in relation to the farming exposures and among professionally active individuals. However, few studies specifically focused on health and aging among elders retired from agriculture. Yet, this population faces the long-term effects of occupational exposures and multiple difficulties related to living and aging in rural area (limited access to shops, services, and practitioners). However, these difficulties may be counter-balanced by advantages related to healthier lifestyle, richer social support and better living environment. The general aim of the AMI cohort was to study health and aging in elderly farmers living in rural area through a multidisciplinary approach, with a main focus on dementia.

Methods/design

The study initially included 1 002 participants, randomly selected from the Farmer Health Insurance rolls. Selection criteria were: being 65 years and older; living in rural area in Gironde (South-Western France); being retired from agriculture after at least 20 years of activity and being affiliated to the Health Insurance under own name. The study started in 2007, with two follow-up visits over 5 years. Baseline visits were conducted at home by a neuropsychologist then by a geriatrician for all cases suspected of dementia, Parkinson’s disease and depression (to confirm the diagnosis), and by a nurse for others. A large panel of data were collected through standardised questionnaires: complete neuropsychological assessment, material and social living environment, psychological transition to retirement, lifestyle (smoking, alcohol and diet), medications, disability in daily living, sensory impairments and some clinical measures (blood pressure, depression symptomatology, anxiety, visual test, anthropometry…). A blood sampling was performed with biological measurements and constitution of a biological bank, including DNA. Brain MRI were also performed on 316 of the participants. Finally, the three-year data on health-related reimbursements were extracted from the Health System database (medications, medical and paramedical consultations, biological examinations and medical devices), and the registered Long-Term Diseases (30 chronic diseases 100% covered by the Insurance System).

Discussion

AMI is the first French longitudinal study on health and aging set up in a population of elderly farmers living in rural area through a multidisciplinary approach.
