BackgroundA higher risk of suicide has been associated with low birth weight in one study, but not yet replicated. Higher birth order has been associated with self-harm, but not with suicide.AimsTo examine the relationship between perinatal circumstances and subsequent young adult suicide in Scotland.MethodUsing linked data from the Scottish Morbidity Record and Scottish death records, a birth cohort of 1 061 830 people was followed-up for a mean of 25.1 years. Data were analysed using Cox regression.ResultsHigher maternal parity, younger maternal age (ConclusionsOur findings provide support for the influence of maternal circumstance and foetal experience on subsequent mental health.

Aims: To explore associations of deprivation and smoking, with prevalence of asthma, wheeze, and quality of life. Methods: Survey, using International Study of Asthma and Allergies in Childhood (ISAAC) methodology, of children aged 13–14 years attending Scottish schools previously surveyed in 1995. Results: 4665/5247 (89%) pupils completed questionnaires. 3656/4665 (78.4%) had missed school for any reason in the last 12 months, 587 (12.6%) because of asthma or wheeze. Compared to children with 1–3 wheeze attacks per year, those with >12 attacks in the last year were more likely to have missed school, twice as likely to have missed physical education in the last month, to report interference with home activities, or to have visited accident and emergency departments, and three times more likely to have been hospitalised. Deprivation was not independently associated with self-reported asthma or wheeze, but was associated with school absence, either for any reason or specifically for asthma or wheeze, but not with use of services such as accident and emergency visits, doctor visits, or hospital admissions. Active smoking was associated with wheezy symptoms, and active and passive smoking with use of medical services. These associations were independent of wheeze severity, treatment taken, and other associated atopic conditions. Smoking also had an impact on school absence and home and school activities. Conclusions: Deprivation does not affect the prevalence of asthma or wheeze. Exposure to cigarette smoke was associated with the increased use of services. Deprivation and smoking have independent adverse effects on the quality of life in subjects with asthma or wheeze.

BACKGROUND: Health professionals in rural primary care could gain more from eHealth initiatives than their urban counterparts, yet little is known about eHealth in geographically isolated areas of the UK. OBJECTIVE: To elicit current use of, and attitudes towards eHealth of professionals in primary care in remote areas of Scotland. METHODS: In 2002, a questionnaire was sent to all general practitioners (n=154) in Scotland's 82 inducement practices, and to 67 nurses. Outcome measures included reported experience of computer use; access to, and experience of eHealth and quality of that experience; views of the potential usefulness of eHealth and perceived barriers to the uptake of eHealth. RESULTS: Response rate was 87%. Ninety-five percent of respondents had used either the Internet or email. The proportions of respondents who reported access to ISDN line, scanner, digital camera, and videoconferencing unit were 71%, 48%, 40% and 36%, respectively. Use of eHealth was lower among nurses than GPs. Aspects of experience that were rated positively were 'clinical usefulness', 'functioning of equipment' and 'ease of use of equipment' (76%, 74%, and 74%, respectively). The most important barriers were 'lack of suitable training' (55%), 'high cost of buying telemedicine equipment' (54%), and 'increase in GP/nurse workload' (43%). Professionals were concerned about the impact of tele-consulting on patient privacy and on the consultation itself. CONCLUSIONS: Although primary healthcare professionals recognize the general benefits of eHealth, uptake is low. By acknowledging barriers to the uptake of eHealth in geographically isolated settings, broader policies on its implementation in primary care may be informed.

Background. Several local anaesthetic techniques are available for cataract surgery. Recently, topical anaesthesia has gained in popularity. A randomized trial was designed to compare patient discomfort and intraoperative complications following routine cataract surgery under topical or sub-Tenon's anaesthesia. Methods. A randomized double-blinded placebo-controlled clinical trial of 210 patients assigned to either a sub-Tenon's group (sub-Tenon's anaesthesia with placebo topical balanced salt solution, n=140) or a topical anaesthesia group (topical anaesthesia with placebo sub-Tenon's injection of balanced salt solution, n=70) was carried out. All patients underwent phacoemulsification with intraocular lens implantation. Patients in the sub-Tenon's group received a single injection (3 ml) of a combination of lidocaine 2% (2 ml) and bupivacaine 0.75% (1 ml), and four doses of topical placebo (balanced salt solution). Patients in the topical anaesthesia group received four doses of topical proxymethocaine 0.5% and a placebo sub-Tenon's injection (3 ml) of balanced salt solution. No intracameral injection of local anaesthetic was given. A 10-point visual analogue pain scale was used preoperatively and for postoperative pain assessment immediately after the operation and 30 min postoperatively. The intraoperative complications in the two groups were recorded. Results. The mean pain score immediately after surgery was 2.42 ( sd 2.2) in the sub-Tenon's group and 3.44 (2.3) in the topical anaesthesia group (P=0.0043). The mean pain score 30 min after surgery was 1.24 (1.7) in the sub-Tenon's group and 2.25 (2.2) in the topical anaesthesia group (P=0.0009). Conclusions. Patients undergoing cataract surgery under topical anaesthesia experience more postoperative discomfort than patients receiving sub-Tenon's anaesthesia. Surgery-related complications were similar in both groups.

Background The prevalence of childhood asthma in Scotland is one of the highest in the world. The morbidity secondary to allergic diseases is significant in terms of costs to the nation and effects on the family including the child. Aims The aims of this study were to describe the prevalence of asthma, eczema and hay fever in the Highlands of Scotland and in the Shetland Isles and to examine factors in relation to quality of life and social deprivation. Method A total population survey of 12 year old children using a parent completed questionnaire. Results 86.3% (2658/3080) returned questionnaires. Of the 2549 questionnaires analysed, 476 (18.7%) reported asthma ever, 362 (14.2%) wheeze in last 12 months, 508 (19.9%) reported hay fever ever and 555 (21.8%) reported eczema ever. Of the children reporting asthma or wheeze, 35.4% (229/647) had missed school because of asthma or wheeze, 38.0% (246/647) had missed physical education. 62.5% (354/566) of subjects with wheeze ever reported sleep disturbance. Deprivation measured by DEPCAT scores was associated with maternal smoking and bronchitis in the child but not with allergic diseases. Conclusion Compared with previous studies, the prevalence of asthma was unchanged but eczema has increased in Highland adolescents. Allergic disease has a significant impact on school attendance and physical activity. Deprivation was associated with maternal smoking and bronchitis in the child but not with allergic diseases. The impact of allergic diseases in rural areas may be different from urban areas.

BACKGROUND: This pragmatic randomised, controlled trial investigated annual review of patients with sleep apnea/hypopnea syndrome (SAHS). Clinical outcomes and costs were compared for consultant clinic review versus specialist nurse home visit. METHOD: One hundred and seventy-four patients were randomised to annual review by consultant clinic appointment or by specialist nurse home visit. SAHS symptoms, Epworth score, hospital anxiety and depression scale (HADS), Short Form-36 (SF-36) and hours of use of constant positive airway pressure (CPAP) were measured before and 3 months after review. The costs and patient preference for review were determined. RESULTS: After review, both groups significantly increased CPAP use (mean (SD) increase: nurse, 0.66 (1.71) h; consultant, 0.45 (1.69) h) and reduced symptom scores (nurse, -2 (7); consultant, -3 (9)), compared to baseline. There were no differences between groups in these improvements, or in HADS or SF-36 scores. Average duration of a nurse home visit, excluding travel time, was 26 (6) min. Total NHS cost per visit was 52.26 UK pounds (49.85) ($83.62 (79.76)), of which 6.57 UK pounds (1.43) ($10.51 (2.29)) reflected time spent with the patient and the remainder was travel cost. Average duration of consultant review was 10 (6) min, total NHS cost 6.21 UK pounds (3.99) ($9.94 (6.38)). However, the cost to the patient of attending the clinic was 23.63 UK pounds (23.21) ($37.81 (37.13)). Patient preference for review was nurse 16%, consultant 19%, and no preference 65%. CONCLUSION: Following annual review, use of CPAP increased and symptoms improved. Outcomes were similar for consultant and nurse led review. Home visits were expensive for the healthcare provider, whereas clinic attendance incurred substantial costs to the patient. The majority of patients would accept nurse review for their sleep apnea management.

Background Inexperience predisposes skiers, snowboarders, and skiboarders to a higher risk of injury. Hypothesis Individuals on their very 1st day's experience of skiing, snowboarding, or skiboarding are at greater risk of injury. Study Design Case control study. Methods All individuals injured at the three largest ski areas in Scotland during the three winter seasons 1999-2000 through 2001-2002 were included. First-day participants were identified. Individual demographic details and snow sports–related parameters were recorded. Control data were collected from uninjured individuals. Factors associated with injury were explored in univariate and multivariate analyses. Results First-day participants were overrepresented in the injured population by a factor of 2.2. Participant age younger than 17 years or older than 26 years, snowboarding, taking professional instruction, and the use of rented or borrowed gear were all independently associated with increased injury risk among 1st-day participants. Conclusions First-day participants are at increased risk of injury. Several independent risk factors for injury have been identified. Clinical Relevance First-day participants should be targeted in any future educational programs with emphasis on gear selection, use of protective gear, and the risks of exceeding the limits of their ability.

Objectives: To examine the incidence and patterns of snow sports injuries at the three largest commercial ski areas in Scotland and to identify factors associated with injury risk. Methods: A prospective case-control study of all injured people at Cairngorm, Glenshee, and Nevis Range ski areas during the 1999–2000 winter season. Personal details, snow sports related variables, diagnosis, and treatment were recorded. Control data were collected at random from uninjured people at all three areas. Random counts were performed to analyse the composition of the on slope population. Results: A total of 732 injuries were recorded in 674 people. Control data were collected from 336 people. The injury rate for the study was 3.7 injuries per 1000 skier days. Alpine skiers comprised 67% of the on slope population, snowboarders 26%, skiboarders 4%, and telemark skiers 2%. Lower limb injuries and sprains were the commonest injuries in alpine skiers and skiboarders. Snowboarders sustained more injuries to the upper limb and axial areas. Skiboarders and snowboarders had a higher incidence of fractures. After adjustment for other variables, three factors were all independently associated with injury: snowboarding (odds ratio (OR) 4.07, 95% confidence interval (CI) 1.65 to 10.08), alpine skiing (OR 3.82, CI 1.6 to 9.13), and age

To assess the clinical outcomes of cataract surgery in rural southern India.Cluster sampling was used in randomly selecting a cross-sectional sample of persons 50 years of age or older for visual acuity measurement, refraction, and ocular examination in 1999. Subjects were queried as to the date and place of surgery for each cataract-operated eye. Surgical complications were noted and the principal cause of reduced vision was identified for eyes with presenting visual acuity worse than 6/18.Within the cataract-operated sample of 682 persons, 13.8% had presenting visual acuity worse than 6/60 in both eyes, 25.2% better than or equal to 6/18 in both eyes, and 37.8% were bilaterally operated on. For aphakic eyes, 50.5% presented with visual acuity better than or equal to 6/18; 82.6% with best-correction. For pseudophakic eyes, the corresponding percentages were 78.0% and 94.5%. Over one-third of all eyes were pseudophakic, and nearly three-fourths had been operated on in non-governmental facilities. Uncorrected aphakia and other refractive error were the main causes of vision impairment. In multiple logistic regression modeling, poor presenting visual acuity in aphakic eyes was associated with illiteracy, rural residence, and surgery in government facilities; gender and time period of surgery were not predictors of vision outcomes. None of these variables were associated with best-corrected outcomes in aphakic eyes, nor with presenting and best-corrected outcomes in pseudophakic eyes.Visual acuity outcomes in pseudophakic eyes were good. More attention must be given to needless vision impairment among the cataract-operated because of inadequate aphakic correction, especially among those operated on in government facilities, the illiterate, and those living in rural villages.

Purpose To define uveitis associated with leptospirosis in a clinical setting. Methods We present the clinical features of 73 consecutive cases of uveitis linked clinically to an outbreak of systemic leptospirosis in patients with antibodies to Leptospira species who were examined from January to September 1994. Results In 73 patients, the pattern of ocular involvement was unilateral in 35 and bilateral in 38. Panuveitis was seen in 106 eyes (95.5%), retinal periphlebitis in 57 eyes (51.4%), and hypopyon in 14 eyes (12.6%). Anterior uveitis alone without hypopyon was observed in three eyes (2.7%), whereas vitreous inflammatory reaction alone was seen in two eyes (1.8%). Sixty of 73 patients (82.2%) or 91 of 111 eyes (82.0%) were followed up for 8 months. Final visual acuity was 6/6 (20/20) in 47 eyes (52%) and improved during treatment, although not up to 6/6, in 15 eyes (16%). Twenty-eight eyes (31%) maintained same vision, and one eye showed deterioration of vision. Conclusion Uveitis associated with leptospirosis may manifest as unilateral or bilateral uveitis, anterior uveitis, or panuveitis. The prognosis is generally good in this entity, even when the inflammation is severe. Awareness of this disease in endemic areas is important in order to differentiate it from other uveitic entities, especially in young male patients in whom other immunologic uveitides are also common.

To describe the methodology and baseline data for the Antioxidants in Prevention of Cataracts (APC) study in South India.The APC study is a prospective, 5-year, randomized, triple-masked, placebo-controlled, field-based clinical trial to examine the effect of antioxidants (combination tablet of vitamins A, C, and E) on progression of cataract. The primary outcome variable is cataract progression (nuclear opalescence), evaluated with the slit-lamp biomicroscope by the Lens Opacification Classification System III method. Secondary outcome variables are progression in cortical and posterior subcapsular opacity and nuclear color, change in best corrected visual acuity, myopic shift, and treatment failure (progression to cataract surgery or best corrected vision worse than 20/400 in an eye). Inclusion criteria are age between 35 and 50 years and best-corrected visual acuity of 20/40 or better. Exclusion criteria are a diagnosis of diabetes mellitus or nonfasting blood glucose level7.8 mmol/L, history or presence of various ocular conditions or treatment forms, or current use of vitamin supplements. Baseline ophthalmic, demographic, and potential cataract risk factor data (such as smoking, sunlight, or alcohol exposure) were compared between groups on an intent-to-treat basis.Of 954 people screened, 798 were enrolled, a sample size which exceeded the required estimate. More than 80% of subjects had 20/20 or better vision in at least one eye, and baseline prevalence of significant cataract according to the LOCS III grading scale was high. The two treatment groups were comparable for all baseline measures except alcohol intake.The sample size and group baseline characteristics will provide sufficient power to detect a change in cataract progression within 5 years.

Background It is believed that total reported suicide rates tend to decrease during wartime. However, analysis of suicide rates during recent conflicts suggests a more complex picture, with increases in some age groups and changes in method choice. As few age and gender specific analyses of more distant conflicts have been conducted, it is not clear if these findings reflect a change in the epidemiology of suicide in wartime. Therefore, we examined suicide rates in Scotland before, during and after the Second World War to see if similar features were present. Methods Data on deaths in Scotland recorded as suicide during the period 1931 – 1952, and population estimates for each of these years, were obtained from the General Register Office for Scotland. Using computer spreadsheets, suicide rates by gender, age and method were calculated. Forward stepwise logistic regression was used to assess the effect of gender, war and year on suicide rates using SAS V8.2. Results The all-age suicide rate among both men and women declined during the period studied. However, when this long-term decline is taken into account, the likelihood of suicide during the Second World War was higher than during both the pre-War and post-War periods. Suicide rates among men aged 15–24 years rose during the Second World War, peaking at 148 per million (41 deaths) during 1942 before declining to 39 per million (10 deaths) by 1945, while the rate among men aged 25–34 years reached 199 per million (43 deaths) during 1943 before falling to 66 per million (23 deaths) by 1946. This was accompanied by an increase in male suicides attributable to firearms and explosives during the War years which decreased following its conclusion. Conclusion All age male and female suicide rates decreased in Scotland during World War II. However, once the general background decrease in suicide rates over the whole period is accounted for, the likelihood of suicide among the entire Scottish population during the Second World War was elevated. The overall decrease in suicide rates concealed large increases in younger male age groups during the War years, and an increase in male suicides recorded as due to the use of firearms. We conclude that the effects of war on younger people, reported in recent conflicts in Central Europe, were also seen in Scotland during the Second World War. The results support the findings of studies of recent conflicts which have found a heterogeneous picture with respect to age specific suicide rates during wartime.

Objectives: To study the nature of CAM use in primary care attenders, the involvement of their NHS healthcare professionals in their CAM care and differences in characteristics between CAM users and non-users. Design: Postal questionnaire for primary care attenders and analysis of practice leaflets. Setting: Six Scottish GP practices with a range of practice size, CAM provision within practice, deprivation and rurality. Results: Five hundred and fourteen primary care attenders described 1194 incidences of CAM use and gave details about their main therapy. 37% had contact with a practitioner, the rest mainly self-prescribed. The perceived effectiveness of CAM was high. Patients used CAM for a variety of health problems, mainly as an adjuvant to orthodox medicine rather than an alternative. The involvement of the NHS in CAM delivery was small but there is a significant role to ensure patient safety, especially regarding herb–drug interactions. Disclosure rate of CAM use was low. CAM offered options in areas where the provision in the NHS is difficult, including musculo-skeletal and mental health problems. Provision of CAM by the GP is associated with higher CAM use in primary care attenders. Conclusions: It is recommended that healthcare professionals include patients’ use of CAM in history taking and clinical decision making.

To assess the prevalence of visual acuity impairment, blindness, and cataract surgery among older adults in rural southern India.Random selection of village- and urban-based clusters was used to identify a cross-sectional sample of persons 50 years of age or older from the Sivaganga district of Tamil Nadu. Subjects in 25 selected clusters were enumerated through a door-to-door survey and invited to examination sites for measurement of uncorrected, presenting, and best-corrected visual acuity and ocular examination in 1999. The principal cause was identified for eyes with presenting visual acuity worse than 6/18. Quality assurance monitoring of visual acuity measurements took place in five of the study clusters.A total of 5081 persons in 3517 households were enumerated, and 4642 (91.4%) were examined. Thirty-six percent presented with visual acuity worse than 6/18 in the better eye. The prevalence of blindness, based on visual acuity worse than 6/60 in both eyes, was 6.0% (95% confidence interval [CI]: 5.1% to 6.9%) with presenting vision, and 2.5% (95% CI: 1.8% to 3.1%) with best correction. Blindness with presenting visual acuity was associated with older age and illiteracy. Cataract was the principal cause of blindness in one or both eyes in 69.4% of those presenting blind, and uncorrected aphakia and other refractive error affected 35.6% in at least one eye. The prevalence of cataract surgery was 14.7% (95% CI: 13.0% to 16.4%); low surgical coverage among the cataract blind was associated with illiteracy.It appears that much has been done in the prevention of blindness in Sivaganga. Nevertheless, blindness remains an important public health problem, mainly because of cataract and refractive error. Prevention of blindness programs in the area should target these two causes, with special emphasis on the elderly and the illiterate.

PURPOSE: To compare the efficacy and safety of ofloxacin 0.3% ophthalmic solution with ciprofloxacin 0.3% ophthalmic solution in patients with culture-positive bacterial keratitis. METHODS: Patients with a microbiologic diagnosis of bacterial keratitis were included in this double-masked, parallel-group study and were randomized to treatment with either ofloxacin 0.3% or ciprofloxacin 0.3% ophthalmic solution. One drop of the study medication was instilled during the daytime according to the following schedule: every half-hour on study day 1, every hour on days 2 through 4, and every 2 hours on days 5 through 21. Healing, the primary outcome measure, was defined as complete reepithelialization, accompanied by nonprogression of stromal infiltrate for 2 days. Secondary outcome measures included signs and symptoms of infection. Patients were monitored throughout the study period for any adverse events. RESULTS: A total of 217 patients completed the study: 112 were treated with ofloxacin and 105 were treated with ciprofloxacin. Streptococcus pneumoniae was the most commonly encountered pathogen in all patients. Complete corneal reepithelialization occurred in 85% of those treated with ofloxacin and in 77% of those treated with ciprofloxacin (p = 0.32). The average time to corneal ulcer healing was 13.7 days in those treated with ofloxacin and 14.4 days in those treated with ciprofloxacin. Both treatments were well tolerated with no patient discontinuing the study because of side effects. CONCLUSION: Ofloxacin 0.3% and ciprofloxacin 0.3% ophthalmic solutions are effective and safe in the treatment of patients with culture-positive bacterial keratitis.

PURPOSE: To estimate the cumulative incidence of posterior capsule opacification 4 years after surgery in patients who participated in the Madurai Intraocular Lens Study and had extracapsular cataract extraction with posterior chamber intraocular lens implantation. METHODS: In the Madurai Intraocular Lens Study, 1,700 patients with best-corrected visual acuity 20/120 or worse in the better eye had extracapsular cataract extraction with posterior chamber intraocular lens implantation, and 1,474 (86.7%) of these completed the 1-year follow-up examination. From this group of 1,474 pseudophakic patients, 400 were randomly selected for reexamination 4 years after the original surgery. The eye that was operated on was examined by an ophthalmologist who was involved in the 1-year follow-up examinations and posterior capsule opacification grading. A grading of I to III was used to reflect the degree of opacification. With grades II and III, posterior capsule opacification detectable with an undilated pupil was present in the central axis. RESULTS: Three hundred twenty-seven (81.8%) of the selected population were examined between October 1997 and December 1998. Thirty-four (8.5%) were confirmed as being deceased, and 39 (9.8%) were unavailable for follow-up. The median age was 60 years, and 57.2% were women. The 4-year incidence of grade II or III posterior capsule opacification, including eyes already treated with laser capsulotomy, was 13.1% (95% confidence interval [CI], 9.7% to 17.3%). Each year of increased age was associated with a decreased risk of posterior capsule opacification (odds ratio, 0.96; 95% CI, 0.92 to 1.00). Based on best-corrected visual acuity of 20/40 or worse without co-existing pathology, the 4-year incidence of posterior capsule opacification was 13.5%. CONCLUSION: Because patients with relatively mature cataracts routinely receive extracapsular cataract extraction with posterior chamber intraocular lens implantation instead of the traditional intracapsular extraction, the subsequent need for laser capsulotomy may be less than that anticipated, based on previous reports.

Objective: To establish the long-term, dose-response relationship between the concentration of and duration of exposure to mitomycin to a decrease in intraocular pressure (IOP) and fewer complications. Methods: We performed a prospective doublemasked, placebo-controlled, 1-year study evaluating the decrease in IOP and fewer complications of fornixbased trabeculectomy surgery in 300 eyes equally divided among therapy with placebo; mitomycin, 0.2 mg/mL, applied for 2 minutes; mitomycin, 0.2 mg/mL, applied for 4 minutes; or mitomycin, 0.4 mg/mL, applied for 2 minutes. All of the eyes had vertical and horizontal cupdisc ratios greater than 0.7. Results: We observed significant treatment-related differences in IOP, with a decrease in IOP in all 3 mitomycintreated groups for all of the times beyond 1 month. The number of eyes achieving strict IOP control and the development of cataract suggest a possible dose-response effect for concentration and time of exposure. Progressive lens opacification was the most frequent complication in 54 eyes (18.1%). The incidence of progressive lens changes markedly increased in subjects receiving 4 minutes of mitomycin therapy. Cataract formation was unrelated to IOP. Other complications were rare. Macular folds developed in 6 patients, with visual acuity returning to better than 20/40 in all but 1 patient. Conclusions: A possible dose-response relationship seemed to exist between the concentration of and duration of exposure to mitomycin. Length of exposure seems to be more important than concentration. The benefits of additional decreases in IOP must be weighed against the potential for increases in the risk of complications.

INTRODUCTION: Farmers and farm workers have higher than expected rates of suicide and undetermined deaths in UK studies, and some rural areas of Scotland have higher than average male suicide rates. Firearm access seems to be an influencing factor in England and Wales. Type of farming, and farming social networks may also be important. This article describes suicide and undetermined deaths in male farmers and farm workers in Scotland from 1981-1999 using anonymised, routine data. METHOD: Deaths of men aged 15-74 years from suicide or undetermined cause were identified from anonymised Scottish death records. Farmers and farm workers were identified using occupation codes. Methods of suicide used by farmers were compared with those of the general male population of the same age. A multiple linear regression was used to examine the influence of farm type, and the proportion of farmers in the working population of an area. RESULTS: 307 male farmers or farm workers died by suicide or undetermined cause in the time period. The overall rate was 31.4/100,000 per year (95% CI 28.1-35.1). Deaths using firearms were over-represented (29% of farming deaths compared with 3.6% in the general male population). There was no significant association between the male suicide rate in an area, and the farming suicide rate. Areas with lower proportions of farmers tended to have higher rates of farming suicide and undetermined deaths. This one factor described 85% of the variance among areas. CONCLUSION: Deaths were substantially more likely to involve firearms than suicide and undetermined deaths in the general male population. Less use of other methods did not completely compensate for this, indicating that method availability is likely to contribute to farming suicide rates. Farmers in areas where farming is less common were more likely to die by suicide, and this described most of the differences among areas. Networks and social supports may be important protective factors for farmers.
