PURPOSE Suicide risk is reportedly higher for cancer patients than for the general population, but estimates vary and analyses of trends are few. The aim of the present study was to determine whether cancer patients had a higher suicide risk between 1960 and 1999. PATIENTS AND METHODS A cohort comprising patients from the Cancer Registry of Norway 1960 to 1997 was linked to suicide diagnosis in the Register of Deaths at Statistics Norway and observed during 1960 to 1999. The cohort consisted of all cancer patients registered in the Cancer Registry of Norway 1960 to 1997 (N = 490,245 patients with 520,823 cancer diagnoses). Suicide was defined according to death certificates based on the International Classification of Diseases (versions 7, 8, 9, and 10). RESULTS During the period, 589 cancer patients (407 males and 182 females) committed suicide. The relative risk was elevated for males and females, with standardized mortality ratios (SMRs) of 1.55 (95% CI, 1.41 to 1.71) and 1.35 (95% CI, 1.17 to 1.56), respectively. Risk was highest in the first months after diagnosis. For both sexes, there was a significant decrease in the relative suicide risk over decades. The risk was markedly increased among male patients with cancer of respiratory organs (SMR, 4.08; 95% CI, 2.96 to 5.47). Otherwise, the SMRs varied from 0.76 to 3.67 across cancer types. CONCLUSION Cancer may be a risk factor for suicide, particularly shortly after diagnosis. However, the relative risk gradually decreased during the period 1960 to 1999.

BackgroundThis study examined the relationship between life satisfaction among medical students and a basic model of personality, stress and coping. Previous studies have shown relatively high levels of distress, such as symptoms of depression and suicidal thoughts in medical undergraduates. However despite the increased focus on positive psychological health and well-being during the past decades, only a few studies have focused on life satisfaction and coping in medical students. This is the first longitudinal study which has identified predictors of sustained high levels of life satisfaction among medical students.MethodsThis longitudinal, nationwide questionnaire study examined the course of life satisfaction during medical school, compared the level of satisfaction of medical students with that of other university students, and identified resilience factors. T-tests were used to compare means of life satisfaction between and within the population groups. K-means cluster analyses were applied to identify subgroups among the medical students. Analysis of Variance (ANOVA) and logistic regression analyses were used to compare the subgroups.ResultsLife satisfaction decreased during medical school. Medical students were as satisfied as other students in the first year of study, but reported less satisfaction in their graduation year. Medical students who sustained high levels of life satisfaction perceived medical school as interfering less with their social and personal life, and were less likely to use emotion focused coping, such as wishful thinking, than their peers.ConclusionMedical schools should encourage students to spend adequate time on their social and personal lives and emphasise the importance of health-promoting coping strategies.

Health status in the ambulance services: a systematic review

Tom Sterud; Øivind Ekeberg; Erlend Hem

BackgroundResearchers have become increasingly aware that ambulance personnel may be at risk of developing work-related health problems. This article systematically explores the literature on health problems and work-related and individual health predictors in the ambulance services.MethodsWe identified the relevant empirical literature by searching several electronic databases including Medline, EMBASE, PsychINFO, CINAHL, and ISI Web of Science. Other relevant sources were identified through reference lists and other relevant studies known by the research group.ResultsForty-nine studies are included in this review. Our analysis shows that ambulance workers have a higher standardized mortality rate, higher level of fatal accidents, higher level of accident injuries and a higher standardized early retirement on medical grounds than the general working population and workers in other health occupations. Ambulance workers also seem to have more musculoskeletal problems than the general population. These conclusions are preliminary at present because each is based on a single study. More studies have addressed mental health problems. The prevalence of post-traumatic stress symptom caseness was > 20% in five of seven studies, and similarly high prevalence rates were reported for anxiety and general psychopathology in four of five studies. However, it is unclear whether ambulance personnel suffer from more mental health problems than the general working population.ConclusionSeveral indicators suggest that workers in the ambulance services experience more health problems than the general working population and workers in other health occupations. Several methodological challenges, such as small sample sizes, non-representative samples, and lack of comparisons with normative data limit the interpretation of many studies. More coordinated research and replication are needed to compare data across studies. We discuss some strategies for future research.

Objectives  Personality types (combinations of traits) that take into account the interplay between traits give a more detailed picture of an individuals character than do single traits. This study examines whether both personality types and traits predict stress during medical school training.

BACKGROUND Suicide rates are higher in certain educational groups. The highest rates are generally found in the medical and allied professions, but the empirical evidence for high suicide rates may be questionable. This study compares the rate of suicide among trained physicians, dentists, nurses, police officers and theologians with the rate among other university graduates and the general population according to sex, age and time period. METHOD Census data from 1960, 1970, 1980 and 1990 relating to education were linked to suicide as cause of death data from Statistics Norway, and followed up for the period 1960-2000, comprising 46 and 49 million person-years among men and women respectively. RESULTS Physicians still have a higher rate compared with other graduates and the general population, both among males [43.0, 95% confidence interval (CI) 35.3-52.5] and females (26.1, 95% CI 15.1-44.9). Suicide rates increased steeply by age among physicians and other graduates, whereas for non-graduates the rate was highest in the 40-60 years age group. The suicide rate among female nurses was also elevated, whereas police officers seemed to have an intermediate suicide risk. The rate among theologians was low (7.0, 95% CI 2.9-16.9). The suicide rates in the 1990s were significantly lower than in the 1980s. CONCLUSIONS The high suicide rates among physicians and elderly graduates are of concern. The reasons why graduates are more vulnerable than others when getting older and the low rate among theologians warrant further study.

BackgroundSelf-prescribing among doctors is common, but no longitudinal studies have documented this issue. We studied the self-prescribing behaviour among young Norwegian physicians and the predictors of self-prescribing.MethodsWe conducted a nationwide, prospective and longitudinal study following young Norwegian physicians from internship through the subsequent nine years using three postal questionnaires. Chi-square tests and logistic regression models were applied.ResultsAbout 54% of the physicians in their fourth and ninth postgraduate years had self-prescribed medication at least once during the previous year. Among those who had used prescription medication during the previous year, about 90% had self-prescribed. Self-prescribing behaviour did not differ significantly between men and women, or according to the type of work at any time. The most frequently self-prescribed medications were antibiotics (71%–81%), contraceptives (24%–25%), analgesics (18%–21%), and hypnotics (9%–12%). Those who had needed treatment for mental problems had self-prescribed hypnotics and sedatives to a greater extent than the others. Being male, having self-prescribed during internship, somatic complaints, mental distress, subjective health complaints, and not having sought help from a general practitioner, were significant adjusted predictors of self-prescribing in the ninth postgraduate year.ConclusionThe level of self-prescribing among young Norwegian physicians is relatively high, and this behaviour is established early in their professional lives. Although self-prescribing is acceptable in some situations, physicians should seek professional help for illness. Efforts to inculcate more rational help-seeking behaviour should probably start in medical schools.

An exploration of job stress and health in the Norwegian police service: a cross sectional study

Anne Marie Berg; Erlend Hem; Bjørn Lau; Øivind Ekeberg

BackgroundPolice work is regarded as a high-stress occupation, but so far, no nationwide study has explored the associations between work stress and health.AimsTo explore physical and mental health among Norwegian police and associations to job stress. Comparisons were made with a nationwide sample of Norwegian physicians and the general Norwegian population.MethodsComprehensive nationwide questionnaire survey of 3,272 Norwegian police at all hierarchical levels, including the Norwegian Police Stress Survey with two factors (serious operational tasks and work injuries), the Job Stress Survey with two factors (job pressure and lack of support), the Basic Character Inventory, the Subjective Health Complaint questionnaire, the Hospital Anxiety and Depression Scale, the Maslach Burnout Inventory, and Paykels Suicidal Feelings in the General Population.ResultsThe frequency of job pressure and lack of support was mainly associated to physical and mental health problems. Females showed higher means on anxiety symptoms than males (4.2, SD 2.9 and 3.7, SD 2.9, respectively; p < 0.01), while males showed higher means on depressive symptoms (3.1, SD 2.9 and 2.4, SD 2.5, respectively; p < 0.001). Police reported more subjective health complaints, depersonalization and higher scores on three of four personality traits than physicians, but lower scores on anxiety and depressive symptoms than the general population.ConclusionThis is the first nationwide study to explore job stress and physical and mental health in police. The results indicate that Norwegian police have high levels of musculoskeletal health problems mainly associated to the frequency of job pressure and lack of support. However, also frequent exposure to work injuries was associated to health problems. This may indicate that daily routine work as well as police operational duties must be taken into consideration in assessing job stress and police health.

The reliability of suicide statistics: a systematic review

Ingvild Maria Tøllefsen; Erlend Hem; Øivind Ekeberg

BackgroundReliable suicide statistics are a prerequisite for suicide monitoring and prevention. The aim of this study was to assess the reliability of suicide statistics through a systematic review of the international literature.MethodsWe searched for relevant publications in EMBASE, Ovid Medline, PubMed, PsycINFO and the Cochrane Library up to October 2010. In addition, we screened related studies and reference lists of identified studies. We included studies published in English, German, French, Spanish, Norwegian, Swedish and Danish that assessed the reliability of suicide statistics. We excluded case reports, editorials, letters, comments, abstracts and statistical analyses. All three authors independently screened the abstracts, and then the relevant full-text articles. Disagreements were resolved through consensus.ResultsThe primary search yielded 127 potential studies, of which 31 studies met the inclusion criteria and were included in the final review. The included studies were published between 1963 and 2009. Twenty were from Europe, seven from North America, two from Asia and two from Oceania. The manner of death had been re-evaluated in 23 studies (40-3,993 cases), and there were six registry studies (195-17,412 cases) and two combined registry and re-evaluation studies. The study conclusions varied, from findings of fairly reliable to poor suicide statistics. Thirteen studies reported fairly reliable suicide statistics or under-reporting of 0-10%. Of the 31 studies during the 46-year period, 52% found more than 10% under-reporting, and 39% found more than 30% under-reporting or poor suicide statistics. Eleven studies reassessed a nationwide representative sample, although these samples were limited to suicide within subgroups. Only two studies compared data from two countries.ConclusionsThe main finding was that there is a lack of systematic assessment of the reliability of suicide statistics. Few studies have been done, and few countries have been covered. The findings support the general under-reporting of suicide. In particular, nationwide studies and comparisons between countries are lacking.

The process of suicidal planning among medical doctors: predictors in a longitudinal Norwegian sample

Reidar Tyssen; Erlend Hem; Per Vaglum; Nina T. Grønvold; Øivind Ekeberg

BACKGROUND The suicidal process is a common underlying perspective on suicidal behaviour, but the process has hardly been empirically studied. This study investigates the process from suicidal thoughts to suicidal planning among physicians; an occupational group with a raised risk of suicide. The process is studied in two ways: First, predictors at medical school of postgraduate suicidal planning are identified. Second, the transition from suicidal thoughts to planning over three to four years is explored. METHODS A nationwide cohort of Norwegian medical students (N=631) were approached initially in their final semester (T1), and then again in the first (T2) and fourth (T3) postgraduate years. The average observation time was 3.6 years. RESULTS Twenty-eight participants (6%) reported suicidal planning in the postgraduate years. Adjusted predictors at T1 were vulnerability trait (neuroticism), severe depressive symptoms, and negative life events. Among those with previous suicidal thoughts at T1, 13 (8%) reported suicidal planning at T2 or T3. Adjusted predictors of transition from thoughts to planning were reality weakness trait, severe depressive symptoms, and a low level of perceived medical school stress. A minority of the postgraduate planners had sought professional care. LIMITATIONS The effect of severe depressive symptoms may be overestimated, and the sample size is relatively small. CONCLUSIONS Common predictors for both postgraduate suicidal planning and transition from thoughts to planning were depressive symptoms and personality traits. Reality weakness was the most decisive trait for aggravation in suicidal ideation, and this personality trait needs further study in suicidal research and clinical awareness.
