Variations in healthcare utilization for mental health problems prior to suicide by socioeconomic status: a Norwegian register-based population study.

BACKGROUND: Suicide poses a major public health challenge, claiming around 650 lives annually in Norway. There is limited understanding of mental healthcare utilization patterns preceding suicide, particularly relating to socioeconomic status (SES). This study analyzes mental health service use among Norwegian citizens aged 20-64 from 2009 to 2021, emphasizing disparities related to SES. METHODS: This is a population-wide registry-based study. We include mental health consultations with both primary and specialist healthcare services, and investigate patterns of service use regarding educational attainment, employment status and income and compare this to the population in general. All suicides in the period (N = 4731) are included in the study. The aim is to investigate potential discrepancies in service use the year and month preceding suicide, seeking to enhance targeted preventive interventions. RESULTS: Our results show significant variations in healthcare use for mental health problems the last year preceding suicide, according to the components of SES, for both men and women. Those with higher education utilize the mental healthcare services prior to suicide to a higher degree than men and women with high school education or less, whereas employed men and men with high income level have significantly lower mental healthcare usage prior to suicide both the last year and month compared to the non-employed men and men with low-income level. Employed women also had a lower mental healthcare usage, whereas the results regarding income are not significant for women. CONCLUSION: Mental healthcare use prior to suicide varies across the SES components. Notably, the SES groups exhibit heterogeneity, with gendered patterns. Targeted interventions for low consultation rates among employed men, and men with high income and lower education are needed, while women, and men in at-risk groups, such as the non-employed and those with low income, demonstrate higher mental healthcare utilization, warranting comprehensive suicide prevention measures.

General practitioner consultations for mental health reasons prior to and following bereavement by suicide.

PURPOSE: Prior research has shown that the majority of those bereaved by suicide express a need for mental health care services. However, there is a lack of knowledge about these individuals' use of primary health care. The objective of our study was to estimate the association between suicide bereavement and general practitioner (GP) consultations for mental health reasons. METHODS: A population-wide, register-based cohort study identifying 25,580 individuals bereaved by suicide. Estimations of increases in consultation rate were modeled through individual fixed-effects linear analyses adjusted for age and time-period. RESULTS: Overall, 35% of those bereaved by suicide had a GP consultation for mental health reasons during the first 1-2 months, and 53% after two years. In the month immediately after bereavement by suicide, there was a large increase in the consultation rate with a GP for mental health reasons. In the months that followed, the consultation rate gradually decreased. One year after bereavement, the consultation rate stabilized at a somewhat higher level than before the death. The increase in consultation rate was evident across all kinship groups, and the increase was greatest for partners and smallest for siblings. Women had more contact with the GP before the suicide and a greater increase in contact than men. CONCLUSION: Our findings suggest that many of those bereaved by suicide seek assistance from primary health care, and that some are in need of prolonged follow-up from the GP. Health governments should be aware of this and seek to strengthen the GPs knowledge of the needs and challenges associated with this patient group. Measures should also be taken to remove barriers to contact the health care system, especially for men and bereaved siblings.

Widening the knowledge of non-employment as a risk factor for suicide: a Norwegian register-based population study.

BACKGROUND: There is a known association between employment status and suicide risk. However, both reason for non-employment and the duration affects the relationship. These factors are investigated to a lesser extent. About one third of the Norwegian working age population are not currently employed. Due to the share size of this population even a small increase in suicide risk is of importance, and hence increased knowledge about this group is needed. METHODS: We used discrete time event history analysis to examine the relationship between suicide risk and non-employment due to either unemployment or health-problems, and the duration of these non-employment periods. We analyze data from the Norwegian population registry from 2004 to 2014, which includes all Norwegian residents in the ages 19-58 born between 1952 and 1989. In total the data consists of 1 063 052 men and 1 024 238 women, and 2 039 suicides. RESULTS: The suicide risk among the non-employed men and women is significantly higher than that of the employed. For the unemployed men, the suicide risk is significantly higher than the employed within the first 18 months. For the unemployed women we only find a significant association with suicide risk among those unemployed for six to twelve months. The suicide risk is especially increased among those with temporary health-related benefits. In the second year of health-related non-employment men have eightfold and women over twelvefold the OR for suicide, compared to the employed. CONCLUSION: There is an association between non-employment and suicide risk. Compared to the employed both unemployed men and men and women with health-related non-employment have elevated suicide risk, and the duration of non-employment may be the driving force. Considering the large share of the working age population that are not employed, non-employment status should be considered in suicide risk assessment by health care professionals and welfare providers.

Marital status, educational attainment, and suicide risk: a Norwegian register-based population study.

BACKGROUND: The presence and quality of social ties can influence suicide risk. In adulthood, the most common provider of such ties is one's partner. As such, the link between marital status and suicide is well-documented, with lower suicide risk among married. However, the association between marital status and educational level suggest that marriage is becoming a privilege of the better educated. The relationship between educational attainment and suicide is somewhat ambiguous, although several studies argue that there is higher suicide risk among the less educated. This means that unmarried with low education may concurrently experience several risk factors for suicide. However, in many cases, these associations apply to men only, making it unclear whether they also refer to women. We aim to investigate the association between marital status, educational attainment, and suicide risk, and whether these associations differ across sexes. METHODS: Our data consist of Norwegian residents aged 35-54, between 1975 and 2014. Using personal identification-numbers, we linked information from various registers, and applied event history analysis to estimate suicide risk, and predicted probabilities for comparisons across sexes. RESULTS: Overall, associations across sexes are quite similar, thus contradicting several previous studies. Married men and women have lower suicide risk than unmarried, and divorced and separated have significant higher odds of suicide than never married, regardless of sex. Low educational attainment inflates the risk for both sexes, but high educational attainment is only associated with lower risk among men. Being a parent is associated with lower suicide risk for both sexes. CONCLUSIONS: Higher suicide risk among the divorced and separated points to suicide risk being associated with ceasing of social ties. This is the case for both sexes, and especially those with low educational attainment, which both healthcare professionals and people in general should be aware of in order to promote suicide prevention.

Marital separation and contact with primary healthcare services for mental health problems: a register-based study.

BACKGROUND: Marital separation is associated with mental health problems, but little is known about how this translates into healthcare use. In this study, we examine the relationship between marital separation and primary healthcare use for mental health problems. METHODS: We used data covering the period from 2005 to 2015 from the Norwegian Population Register, Statistics Norway's Educational Registration System and the Norwegian Health Economics Database. Data were analyzed using logistic regression analysis. To control for time invariant characteristics, we estimated fixed-effect models. RESULTS: Marital separation was associated with increased contact with primary healthcare services for mental health problems (MH-consultations). The prevalence of MH-consultations peaked during the year of marital separation. MH-consultations were more common following marital separation than prior to the separation. This pattern remained significant in the fixed-effect models. CONCLUSIONS: Men and women who experienced marital separation were more likely to consult primary healthcare services for mental health problems than those who remained married. Our study suggests that several mechanisms are in play. The prevalence of MH-consultations of those who eventually separated were higher several years prior to the separation. This lends support to selection mechanisms, whereas the sharp rise in the prevalence of MH-consultations around the time of marital separation coupled to higher levels several years after separation, indicate that marital separation induces both transient stress and leads to more lasting strain.

Use of primary healthcare services prior to suicide in Norway: a descriptive comparison of immigrants and the majority population.

BACKGROUND: There is an increase in studies investigating the use of healthcare services prior to suicide. Although studies generally report high usage, there are no previous studies comparing immigrants' use of primary healthcare (PHC) prior to suicide with that of majority populations. There is a strong influx of immigrants in Europe, and thus a growing demand for filling this knowledge gap and exploiting unused potential for suicide prevention. METHOD: By linking three national registers, we examine contact with PHC prior to suicide in all suicide cases in Norway from 2007 to 2014 among individuals aged 15 years and over (N = 4341). We report the percentage of individuals in personal contact within the last 6 months, 1 month and 1 week prior to suicide, and use the chi square-test for association. RESULTS: Overall, immigrants have less contact with PHC prior to suicide. We find significantly lower rates of contact among immigrants, both 6 months and 1 month prior to suicide, for both sexes. The trend is similar in the last week prior to suicide, but less pronounced. The largest variance in contact with PHC prior to suicide is amongst 30-44 year olds. Young, male immigrant suicide victims have the lowest rates of contact with PHC prior to suicide. Contact rates increase with age for all men and women in the majority population, but not for female immigrant suicide victims. CONCLUSIONS: There is a clear difference in rates of contact with PHC prior to suicide between the majority and immigrant populations. The rates are especially low among young males, and measures should be made to lower their threshold for consulting PHC for young males in general and young male immigrants in particular. The difference in contact due to immigrant status appears to be of equal importance as the difference due to sex, although, with few significant results, a conclusion is hard to draw.

Use of primary health care services prior to suicide in the Norwegian population 2006-2015.

BACKGROUND: Studies report high rates of contact with general practitioners (GPs) in primary care in the time leading up to suicide, particularly among individuals with a history of mental health contact. However, the near lack of studies including population representative controls have prevented investigations into how the contact patterns of suicide victims compares to those of the general population. METHODS: By linking data from two national registries, this study investigated primary health care use in suicide victims aged 15 years and older during the period from 2007 to 2015 (n = 4926). Their rates of contact one year and one month prior to suicide were compared to the average rates in the general Norwegian population during the period by estimating relative risks across sex and age. Contact patterns one month prior to suicide were also investigated according to prior mental health consultations in primary care. RESULTS: The findings revealed a stable trend in contact with GPs in primary care during the observation period, with 79.6% of male and 89.0% of female suicide victims having consulted their GP within a year of the suicide. Corresponding rates one month prior to the suicide were 34.8 and 46.4%, respectively. At both points in time and across all age groups, suicide victims were considerably more likely to consult their GP than were the general population. Suicide victims without prior mental health contact were only modestly more likely to consult their GP within a month of the suicide as compared to the general population, while both the general population and suicide victims with prior mental health consultations had rates of contact well above those without, evident for both sexes. CONCLUSIONS: Contact with GPs in primary care prior to suicide is common in both sexes and across most age groups, in particular for victims with prior mental health consultations. Younger males show the overall lowest rates of contact, and increased alternative efforts to reach this group, in addition to larger population strategies, may pose the most prominent preventive measures.

A Registry Based Approach to Suicide Research: Opportunities and Limitations in the Norwegian Population Representative Registries.

Together with the other Nordic countries, Norway stands in a unique position internationally with its large population representative registries. By means of unique personal identification numbers assigned to all Norwegian citizens, as well as to immigrants who stay for more than 6 months, it is possible to construct individual record linkages covering an increasing number of years across different national registries. The Norwegian registries include, among others, information from the primary and specialist health care services, the prescription of drugs, and causes of death. In addition, they include sociodemographic information like year of birth, gender, immigration status, educational attainment, marital status, and the use of various social benefits. Norway is one of very few countries that have a nationwide registry on primary health care use. This registry gives the opportunity to explore the role of the primary health care services prior to suicide and in the follow-up of the suicide bereaved, which has been pointed out as one of the most promising areas for future suicide prevention. Linkages of Norwegian registries opens up new approaches in analyses and the possibility to explore a range of novel research themes, such as treatment trajectories and patterns of health care use prior to suicide and among the suicide bereaved. In this paper, we give a description of the Norwegian population representative registries applicable for suicide research. We discuss the analytic opportunities as well as the challenges and obstacles of a registry based research approach to suicide. The main strength of registry-based research on suicide is the ability to maintain data on the total population, the possibility to study small sub-populations or low-prevalent events, virtually continuous timelines in longitudinal data, few or no non-response or other missing data, no sample attrition, and the possibility of gaining access to large amounts of various health and sociodemographic information. In addition registry-based research allows investigation of hard-to-reach populations, such as groups of individuals with severe mental disorders or immigrants that traditionally have been difficult to recruit for participation in research projects. The opportunities presented in the article could motivate to do similar research in Canada and even inspire for cooperation between Norwegian and Canadian researchers on registry based research on suicide. In our opinion, registry-based research on suicide will play an increasingly important role in suicide research in the years to come.
