Introduction: Suicides are number 16 as a cause of death worldwide. Causes are not always known, often associated with depression or trauma. Suicide incidence has decreased world- wide in the past three decades. The economic crisis of 2008 led to an increase in many countries. Many confounding factors make comparisons between countries difficult. This study assesses the possible impact of economic crises in Iceland on suicide incidence., Material and Methods: The work is based on suicide data from 1911 to 2017 and six economic crises from 1918 to 2008. The incidence is calculated five and ten years before and after the index year of each crisis. Possible crisis impact was assessed by applying a quasi-Poisson model to the data. Variance can be greater than model shows, so overdispersion was assessed. The evolution over time is assessed by inspection of cumulative sum of squared -residuals (CUSUMSQ)., Results: Suicide incidence increased from 1930, beginning to decline around 1990. Given a small population size there are wide upwards incidence fluctuations, within and outside the crisis -periods. The crises of 1931 and 1948 showed an increase, wheras in the others there is no change or a decrease. The sizes of deviations from expected value are, for the whole period, in compliance with the quasi-poisson model for counts., Conclusion: There is no statistical correlation between the six economic crises and suicide incidence in the Icelandic data. The study is based on population incidence and does not preclude a negative impact of economic crises on individuals.

Objective: To analyze the long-term outcome for recipients of disability pension in Iceland., Material and Methods: The study includes all those receiving disability pension for the first time in 1992 in Iceland. Their status in the disability register at the State Social Security Institute of Iceland November 30th 2004 was examined as to whether they were still receiving disability pension, had died, had reached the age of retirement or were not receiving disability pension any more for some other reasons., Results: In 1992 there were 725 new recipients of disability pension in Iceland, 428 females and 297 males. Twelve years later 434 from this group were no longer receiving disability pension, 240 females and 194 males. In most cases this was because they had reached the age of retirement or died (on average 88% of the females and 91% of the males each year). Only 12% of the females and 9% of the males ceased to receive disability pension (and probably went back to work)., Conclusion: In Iceland few people return to work once they have started receiving disability pension.

Objective: To evaluate the effect of unemployment and the introduction of a new method of disability assessment on the number of recipients of disability pension in Iceland by examining changes in the incidence of disability pension and unemployment year by year from 1992 to 2003., Material and Methods: Information on gender, age and disability grade of new recipients of disability pension in Iceland and corresponding information on the Icelandic population for each year in the period 1992 to 2003 was used to calculate the incidence of disability pension. The results were compared with data on the rate of unemployment in Iceland., Results: The incidence of disability pension was relatively high from 1992 to 1995, was lower from 1996 to 2002 and then increased markedly in 2003. There is a strong correlation between the incidence of disability pension and the rate of unemployment among both genders in Iceland during the period covered by the study. An increase from 1999 to 2000 in the incidence of disability pension among females coincided in time with the introduction of a new method of disability assessment in September 1999, but also with an increase in the rate of unemployment among females., Conclusion: It is not warranted to claim that the introduction of a new method of disability evaluation in September 1999 has resulted in a decisive increase in the incidence of disability pension in Iceland. The increase in the number of recipients of disability pension in Iceland recently has a strong statistical correlation with changes in the labour marked, especially with rising unemployment and increased pressure at work.

Objective: This study was part of a geographically defined national study on survival, health, development, and longterm outcome of extremely low birthweight infants (ELBW; birthweight < 1000g) in Iceland focusing on development and neurodevelopmental measures in comparison to a reference group., Methods: All 35 ELBW longtime survivors born in 1991-95 and 55 children as matched reference group were enrolled in a prospective study on longterm health and development. The children underwent medical examinations and neurodevelopmental testing at five years of age in 1996-2001, and their parents answered a questionnaire on their behavior. Comparison was made between ELBW infants and the reference group. Revised (WPPSI-R) showed significantly lower full scale IQ scores for the ELBW group compared to the reference group (p<0.001). More difference was apparent between the groups for the performance IQ than the verbal IQ. Scores on Test of Language Development (TOLD-2P) showed differences between the ELBW group and the reference group on the total language quotient (p=0.025). Significant differences were not obtained between the groups on TOLD-2P s individual subtests, languistic features nor linguistic systems. Total Scores on the Miller Assessment for Preschoolers (MAP) with emphasis on sensory motor development, were significantly lower for the ELBW group compared to the reference group (p<0.001). Additionally, significant differences were found on three of five subscales of the MAP. Evaluation of fine motor skills with the Finmotorisk utvecklingsstatus 1-7aar (FU) revealed significant differences (p<0.001), favoring the reference group. Parental answers on the Child Behavior Checklist (CBCL) showed differences between the groups on three of eight factors in favor of the reference group (p<0.001)., Conclusions: Developmental testing at five years of age indicates that the performance of 25% of the ELBW children in this study, is consistent with that of same age peers. However, as a group, the ELBW children performed significantly poorer regarding cognitive development and sensory-motor skills when compared to the reference group. The most prominent neurodevelopmental difficulties of the ELBW children were within perceptual organization, coordination, and executive skills. Behavior problems were not rated as significant according to parental answers, although there were some differences between the groups. Since a large portion of ELBW children experiences developmental problems, it is important to provide early intervention during preschool years and support services and special education during school years, to reduce the longterm effects of developmental deficits.

Aims: To evaluate the main characteristics which differentiate between those who are considered to benefit from rehabilitation and those for whom disability pension is thought more appropriate., Material and Methods: The study includes all those fulfilling the medical criteria for rehabilitation benefits or full disability pension in their first assessment at the State Social Security Institute of Iceland between September 1st 1999 and November 30th 2003., Results: Rehabilitation benefits were mainly awarded in younger age groups; disability pension in older age groups. Mental and behavioural disorders were the most common medical reasons for granting rehabilitation benefits among both genders, followed by disorders of the musculoskeletal system and connective tissue, malignant neoplasms and injuries. Among females disorders of the musculoskeletal system and connective tissue were the most common medical reason for granting full disability pension, but this group of disorders was a less common reason for rehabilitation benefits. Those who fulfilled the medical criteria for rehabilitation benefits due to disorders of the musculoskeletal system and connective tissue were markedly older than those who fulfilled the medical criteria for rehabilitation benefits due to mental and behavioural disorders., Conclusion: In Iceland rehabilitation benefits are most likely to be awarded to relatively young claimants suffering from psychiatric disorders.

Aims: To determine the prevalence of disability in Iceland on December 1st 2002 due to mental and behavioural disorders according to gender, place of residence and marital status and main subcategories., Material and Methods: The disability register of the State Social Security Institute was used to obtain information on the number, gender, age, place of residence, marital status and main diagnosis of recipients of disability pension. From Statistics Iceland the same information was obtained for the Icelandic population between the age of 16 and 66., Results: The prevalence of disability due to mental and behavioural disorders was 2.32% for females and 1.98% for males. For males receiving disability pension the proportion having mental disorders as the main cause of disability was larger than for females. Among females the most common cause of disability was mood disorders whereas among males it was schizophrenia, schizotypal and delusional disorders. Most of those with schizophrenia, schizotypal and delusional disorders in Iceland receive full disability pension. The prevalence of disability due to mental and behavioural disorders was significantly higher in the capital region than in the rest of the country. Marriage and registered co-habitation was considerably less common among recipients of disability pension due to mental and behavioural disorders than among the nation in general., Conclusion: The prevalence of disability due to mental and behavioural disorders in the capital region is in excess of what is to be expected from the prevalence of these disorders and from disability in general in Iceland. The relatively high prevalence of disability due to mental and behavioural disorders among males is in line with epidemiological data. The prevalence of disability due to mental and behavioural disorders in Iceland has been rising. This needs to be addressed by improving vocational rehabilitation programs for those suffering from these disorders.

Objective: To determine the size and main medical and social characteristics of the group of individuals receiving disability benefits in Iceland in December 2002 and compare the results with figures from 1996., Material and Methods: The study includes all those receiving disability benefits on December 1st 2002 and December 1st 1996 as ascertained by the disability register at the State Social Security Institute of Iceland. Information on age and gender distribution of the Icelandic population was obtained. Age-standardized risk ratio between the years 1996 and 2002 was calculated for both pension levels combined and for full disability pension alone., Results: On December 1st 2002 there were 11,791 individuals receiving disability benefits, 7044 women (59.7%) and 4747 men (40.3%). Of these there were 10,960 individuals receiving full disability pension, 6500 women (59.3%) and 4460 men (40.7%). The prevalence of all disability pension was 6.2%; full disability pension 5.8% and partial disability pension 0.4%. The prevalence of disability was lower in the capital region compared with other regions of Iceland among women, but among men there was no significant difference in the prevalence of disability according to residence. The prevalence of disability increased with age. On the whole disability was more common among women than men, but in the age group 16-19 years it was more common among men than women. Mental and behavioural disorders and diseases of the musculoskeletal system and connective tissue were the most prevalent causes of disability. The standardized risk ratio showed a significantly increased risk for both pension levels combined and for full disability pension alone both for men and women in the year 2002 as compared with the year 1996., Conclusion: The increase in the prevalence of disability in Iceland between the years 1996 and 2002 is probably mainly due to the introduction of a new method of disability evaluation in 1999 and increased pressure from the labour market, with increasing unemployment and competition. Mental and behavioural disorders are the most common cause of disability in Iceland and there has been a marked increase in disability due to these disorders since 1996.

Objective: Survival of extremely low birthweight infants (BW<1000g) in Iceland has increased in recent years, especially since the availability of surfactant therapy for Respiratory Distress Syndrome of Prematurity. This study was part of a geographically defined national study on survival, health, development and longterm outcome of extremely low birthweight (ELBW) infants in Iceland focusing on health, development and disabilities with reference to a control group., Material and Methods: Information from the National Birth Registry on births in Iceland of ELBW infants weighing 500-999g was collected in two periods 1982-90 and 1991-95, before and after surfactant therapy became available. Information on pregnancy, birth, diseases in the newborn period and later health problems was collected from hospital records. The ELBW infants born in 1991-95 and matched control children were enrolled to a prospective study on longterm health and development. The children undervent medical examinations and developmental testing at 5 years of age in 1996-2001. Comparison was made between the two groups of ELBW infants and between ELBW infants and control children born in 1991-95., Results: In 1982-90 the longterm survival of ELBW infants at 5 years of age was 22% and 52% in 1991-95. In both periods 1982-90 and 1991-95 similar data was found on ELBW infants regarding mothers health, pregnancy, birth and neonatal period. Difference was found in maternal age being significantly higher (p=0.02) and significally more deliveries by cesarian section (p=0.02) in the latter period. The two groups of ELBW infants were similar regarding sex, birthweight and diseases in the newborn period. Comparison between 35 ELBW infants and 55 control children born 1991-95 showed that significantly more mothers of ELBW children smoked during pregnancy (p=0.003) and suffered from various diseases (p=0.001). More ELBW children were born by cesarian section (p=0.001) than control children and their parents reported more longterm health problems regarding astma (p=0.001), convulsions (p=0.001), difficulties in swallowing (p=0.001) and weight gaining (p=0.005). At five years of age significantly more ELBW children born in 1991-95 compared to control children had abnormal general physical examination (p

Objective: In recent years advances in medical care and technology have increased newborn survival rate, both fullterm and preterm. This is reflected in a low Perinatal Mortality Rate in Iceland. Survival of extremely low birthweight infants (ELBW with BW<1000g) has also increased, especially since the availability of surfactant therapy for Respiratory Distress Syndrome of Prematurity. The purpose of this geographically defined national study was to evaluate survival and longterm outcome of ELBW children in Iceland., Material and Methods: Information on all births in Iceland 1982-95 was collected from the National Birth Registry and Statistics Iceland with information on ELBW infants weighing 500-999g born in two periods 1982-90 and 1991-95, before and after the use of surfactant became routine therapy. Information on disability was obtained from records at the State Social Security Institute. Comparison was made between the two groups of ELBW infants., Results: In 1982-90 the proportion of ELBW infants was 0.3% of all births (116 of 38.378) and longterm survival at five years of age was 19 of 87 liveborn children or 22%. In 1991-95 ELBW infants were 0.5% of all births (102 of 22.261) and longterm survival was 35 of 67 liveborn children or 52%. Of the 19 ELBW children born in 1982-90 three are considered handicapped (16%) and 6 of 35 ELBW children born in 1991-95 (17%)., Conclusions: The study shows that at the same time that proportionally more children are of extreme low birthweight, the survival of ELBW infants has increased from 22% in 1982-90 to 52% in 1991-95. The proportion of ELBW children with disability is not increased significantly between the two periods.

Objective: The etiology of fibromyalgia is unclear. The diagnosis is based on widespread pain and muscular tenderness, but other symptoms often occur, such as sleep disturbance, excessive anxiety and fatigue and concentration difficulties. All these symptoms can occur in generalized anxiety disorder. The aim of this study was to assess whether fibromyalgia is associated with other diagnoses, particularly anxiety disorder., Material and Methods: The study includes all those receiving full disability pension on the 1st of December 2001 as ascertained by the disability register at the State Social Security Institute of Iceland. Information was obtained from the register on gender, age and diagnoses of the disability beneficiaries. Diagnoses were compared between two groups of disability beneficiaries - an index group with fibromyalgia and a comparison group without that diagnosis. There were 716 women in each group. We also compared diagnoses among the women who had fibromyalgia as primary diagnosis in the index group and among all women who had anxiety/depression as primary diagnosis., Results: In the index group fibromyalgia was the single registered diagnosis in only 6.8% of cases, while 38.3% of the comparison group had a single registered diagnosis. There was a significant difference between the two groups in terms of the number of diagnoses by disease category (p<0.0001). Among individual categories of disease, the only category that showed a significant excess in the index group was mental disorders (p<0.0001). Women with fibromyalgia as a primary diagnosis were compared with women with a primary diagnosis of anxiety or depression in terms of distribution of the numbers of diagnoses per person. The distribution pattern was similar., Conclusions: The probability of having a mental disorder, especially an anxiety disorder, is significantly higher amongst women with fibromyalgia as compared to other women with full disability pension. This indicates an association between fibromyalgia and anxiety, an association which needs to be properly addressed in the treatment of this disorder.

Objectives: Evaluation of opinions of those evaluated by a multidisciplinary team on the evaluation, vocational rehabilitation they participated in and on the effect of the process on their self-confidence and self-reliance., Material and Method: The Institute of Social Sciences carried out a telephone survey in October 2001, where it was attempted to contact the 109 individuals evaluated for rehabilitation potential by a multidisciplinary team in the year 2000. The data was analysed using descriptive statistics., Results: 83 (76.1%) replied. After the evaluation 40 individuals were referred to vocational rehabilitation for approximately 2 months in a rehabilitation clinic; 19 were referred to a 6 week personal computer training at a vocational rehabilitation centre and 15 to a longer (usually 18 months) rehabilitation program in the same centre. Approximately 80% were content with the vocational rehabilitation offered. 54% of those evaluated by the multidisciplinary team said that it had been useful for them to meet the members of the team and 59% said that the team had informed them on resources they had not been aware of. Approximately half of the participants said that their self-confidence and self-reliance had increased., Conclusion: Approximately 80% of the participants were content with the vocational rehabilitation offered and approximately 50% had gained more self-confidence and self-reliance.

Objective: The evaluation of a vocational rehabilitation programme initiated by the State Social Security Institute in Iceland (SSSI) in 1999 with the aim of reducing disability., Material and Methods: New disability claimants who had been unable to work because of illness for a few months at least were referred by SSSI physicians to a multidisciplinary team for assessment of rehabilitation potentials and an advice on the appropriate type of rehabilitation. The study group included all the 109 individuals who were referred to the team in the year 2000. Data on marital status, number of children and level of education was compared with information about the Icelandic population obtained in a national survey. The outcome of the rehabilitation was assessed in a telephone survey, carried out by the Social Science Research Institute, University of Iceland, 1-2 years after the assessment and by information obtained from the disability register at SSSI. The effectiveness of the rehabilitation programme was evaluated by comparing the study group with a comparable group that had started to receive rehabilitation pension before the SSSI could offer vocational rehabilitation. Their progress was assessed a year and half after they had contacted the SSSI, the same length of time as the study group had been in the in the rehabilitation programme., Results: In the study group there were about twice as many women as men. The mean age was 35 years (range 18-57 years). The main medical reasons for referral to the team were musculosceletal and psychiatric disorders. Those evaluated were more likely to be unmarried or divorced, had more children and a lower educational level than the general Icelandic population. After evaluation 40 individuals were referred to vocational rehabilitation for approximately 2 months in a rehabilitation clinic; 19 were referred to a 6 week personal computer training at a vocational rehabilitation centre and 15 to a longer (usually 18 months) rehabilitation program in the same centre. In all, 46 individuals received other treatment or education. Almost three quarters (72%) of the participants in the telephone survey said that their fitness for work had increased after rehabilitation, but only 47% had returned to work. At the time of the reserach, 23% were students and it is likely that a part of them will return to work when their studies are completed. Between one and two years after the evaluation by the multidisciplinary team 44 out of 109 (40.4%) in the study group received disability pension and a equal number received no social insurance benefits at all. In the comparison group 97 out of 119 (81.5%) received disability pension and 21 (17.7%) received no social insurance benefits at all., Conclusions: This study shows that vocational rehabilitation organized by the SSSI is effective and can prevent disability. The results of this study are similar to the results of two Swedish studies on the same topic.

Introduction: All claims for disability benefits in Iceland are managed by the State Social Security Institute of Iceland. The decision to grant a claimant disability benefits was until September 1999 mainly based on medical certificates but social and economic factors were also taken into consideration. As information on social and economic conditions in medical certificates is limited it was decided to investigate these factors particularly. In this paper a comparison of educational level, employment, and income is made between new recipients of disability benefits and a random sample of the Icelandic nation., Material and Methods: All new recipients of disability benefits (full disability pension, partial disability pension and rehabilitation pension) in 1997 were contacted by phone and asked to answer a questionnaire. Their answers were compared with those obtained in a national survey carried out by the Institute of Social Sciences at the University of Iceland in 1996 and 1997 with a sample representing accurately the Icelandic population in terms of gender, age and place of residence. Information about average income of disability pensioners was obtained and compared to that of people in employment., Results: Educational level of those receiving disability benefits was considerably lower than expected in comparison with the population and unskilled workers were overrepresented. Contrary to what might be expected a larger proportion of the recently disabled have been employed at some time than is the case for the national sample, even though 63.6% of the new disability pensioners were women. Considerable number of those receiving disability benefits were still in employment, particularly those with partial disability pension. Mean monthly income of Icelanders participating in the labour market was almost twice that received by those on disability benefits., Conclusions: Since lower educational level and more restricted employment opportunities characterize disability pensioners as compared to the nation, it seems likely that more varied occupational rehabilitation and educational opportunities could improve the situation of those who have had to leave the labour market because of ill health, lack of education and poor working conditions.

Objective: To assess changes in disability evaluation, since the introduction on September 1st 1999 of a new assessment method based on the British functional capacity evaluation, "All work test". Previously, the disability assessment was based on the applicant's medical, social and financial circumstances., Material and Methods: The study includes all those having their disability assessed for the first time at the State Social Security Institute of Iceland in 1997, 1998 and 2000. Information was obtained from the disability register on degree of disability, gender, age and primary diagnoses., Results: After the introduction of the new assessment method, there has been a significant increase in the number of women who have disability more then 75% (p<0.0001). This increase occurs amongst women older than 30 years, having musculoskeletal disorders (mainly soft tissue disorders). There has also been a slight (statistically insignificant) increase in more than 75% disability amongst men (p=0.25). The number of people who have had their disability evaluated as 50-65% has decreased (p<0.0001). No significant change in the total number of new disability pensioners (having their disability assessed as being more than 75% or 50-65%) was observed., Conclusions: The new method of disability assessment has resulted in a significant rise in the number of women who have had their disability assessed as being more than 75%, but there has not been a rise in the total number of new disability pensioners, as the increased number of women with the higher degree of disability has been balanced by a significant fall in the number of new disability pensioners with the lower degree of disability.

Objective: To determine changes in the prevalence of disability pension in Iceland and to describe the distribution of those receiving disability pension according to gender, age and main diagnoses between the years 1976 and 1996., Material and Methods: The study includes all those receiving disability pension on the 1st of December in the years 1976 and 1996 as ascertained by the disability register at the State Social Security Institute of Iceland. There are two levels of disability pension, full disability pension (disability assessed as being more than 75%) and reduced disability pension (disability assessed as being 50% or 65%). Information on age and gender distribution of the Icelandic population was obtained. Age-standardized risk ratio between the years 1976 and 1996 was calculated for both pension levels combined and for full disability pension alone., Results: There was no significant change in crude prevalence rate for both pension levels combined between the years 1976 and 1996, when the increase in the population was accounted for but without paying attention to changes in gender or age distribution. However, the standardized risk ratio showed a significantly decreased risk for both pension levels combined both for men and women in the year 1996 as compared with the year 1976, the age-standardized risk ratio being 0.95 and 0.93 respectively. It also showed a significant change between pension levels with an increased risk of full disability pension and a decreased risk of reduced disability pension. The increase in full disability pension was noted for both males and females and was largely independent of age. There was a significant increase in full disability pension in most disease categories. Disability due to diseases of the nervous system and sense organs and injury and poisoning increased amongst women only. A significant decrease in full disability pension due to infections and diseases of the digestive system occurred in both men and women., Conclusion: The prevalence of a disability pension amongst men and women in the year 1996 as compared to the year 1976 was significantly decreased when changes in population size and age distribution had been accounted for. This is particularly interesting because unemployment was increasing just prior to the year 1996. The prevalence of full disability pension had however significantly increased in 1996 compared with 1976. A plausible explanation for the observed change in disability pension levels is a pressure from the labour market, with increasing unemployment and competition. Also, the introduction of a disability card for those with full disability pension in 1980, which granted lower price for medication and the services of physicians, is likely to have increased the pressure for the higher level of disability pension (full disability pension). It seems unlikely that the increase in full disability pension and the decrease in reduced disability pension is due to a deterioration of health of the Icelandic population. Increased disability due to injury and poisoning amongst women is probably a result of their increased participation in the labour market. The decrease in disability due to infections is a result of a reduction in the number of cases of tuberculosis and poliomyelitis. The decrease in disability due to diseases of the digestive system is probably a result of improvement in the treatment of oesophageal reflux and peptic ulcer.
