Trends in health inequalities by educational level in a Norwegian total population study

Objective: To describe levels of inequality and trends in self reported morbidity by educational level in a total Norwegian county population in the mid-1980s and mid-1990s. Design: Two cross sectional health surveys at an interval of 10 years in the Nord-Trøndelag Health Study, HUNT I (1984–86) and HUNT II (1995–97). Setting: Primary health care, total county population study. Participants: Men and women, 25–69 years. Main results: There was a consistent pattern of increasing self reported health problems with decreasing educational level for three health variables: perceived health, any longstanding health problem, and having a chronic condition. A stable or slight decrease in inequalities over time was found. The prevalence odds ratio for perceived health less than good were 2.71 for men (95% confidence intervals (CI): 2.39 to 3.09) and 2.13 for women (95% CI: 1.85 to 2.46) in the first survey, 2.51 for men (95% CI: 2.27 to 2.78) and 2.06 for women (95% CI: 1.88 to 2.26) 10 years later. Conclusions: The magnitude of the socioeconomic gradients in health in this population seemed somewhat lower than in Norway as a whole and close to the average in studies from other European countries. There was a slight trend towards smaller differences despite rapid structural changes in working life, turbulence in economy, and more people experiencing unemployment.

Disability in society—medical and non-medical determinants for disability pension in a Norwegian total county population study

The objective of this study was to describe sociomedical determinants and developments for the medically based disability pension in Norway by linking individual based data from a county health survey to data on disability from the National Insurance Administration. Two cross-sectional total population health surveys with an approximate 10-year interval were conducted in Nord-Trøndelag county, HUNT I (1984-86) and HUNT II (1995-97), which allows for analyses of changes over time, supplied with official incidence data on disability pension. The large-scale variations and overall increasing incidence rates of disability pension in Norway during the last 20 years also applied to the county of Nord-Trøndelag. The prevalence of disability pension generally increased in the population from the mid-1980s to the mid-1990s. A striking finding was a consistent pattern of increasing prevalence of disability pension with decreasing socio-economic status and education. A geographic pattern for disability pension prevalence on a municipality level suggested that structural and cultural factors were important in determining the level of disability in society. Medical determinants alone cannot explain either the dramatic variations or the overall increased incidence rates of disability pension in the last two decades in Norway. The results demonstrate the importance of social, non-medical and contextual determinants for disability pension, how these determinants result in important prevalence differences by socio-economic status, and their impact on the level of disability in society.

School dropout: a major public health challenge: a 10-year prospective study on medical and non-medical social insurance benefits in young adulthood, the Young-HUNT 1 Study (Norway)

Background School and work participation in adolescence and young adulthood are important for future health and socioeconomic status. The authors studied the association between self-rated health in adolescents, high school dropout and long-term receipt of medical and non-medical social insurance benefits in young adulthood. Methods Self-rated health in adolescence was assessed in 8795 adolescents participating in the Norwegian Young-HUNT Study (1995–1997). Linkages to the National Education Database and the National Insurance Administration allowed identification of school dropout and receipt of long-term medical and non-medical benefits during a 10-year follow-up (1998–2007). The data were explored by descriptive statistics and by multinomial logistic regression. Results A total of 17% was registered as being high school dropouts at age 24. The predicted 5-year risk of receiving benefits between ages 24–28 was 21% (95% CI 20% to 23%). High school dropouts had a 5-year risk of receiving benefits of 44% (95% CI 41 to 48) compared with 16% (95% CI 15 to 17) in those who completed high school (adjusted for self-rated health, parental education and sex). There was a 27% school dropout rate in adolescents who reported poor health compared with 16% in those who reported good health. The predicted 5-year risk of receiving any long-term social insurance benefits in adolescents who reported poor health was 33% (95% CI 30 to 37) compared with 20% (95% CI 19 to 21) in those who reported good health. Conclusion The strong association between poor self-rated health in adolescence, high school dropout and reduced work integration needs attention and suggests preventive measures on an individual as well as on a societal level.

Socioeconomic inequalities in health care utilisation in Norway: the population-based HUNT3 survey

BackgroundIn this study we investigated the distribution of self-reported health care utilisation by education and household income in a county population in Norway, in a universal public health care system based on ideals of equal access for all according to need, and not according to wealth.MethodsThe study included 24,147 women and 20,608 men aged 20 years and above in the third Nord-Trøndelag Health Survey (HUNT 3) of 2006–2008. Income-related horizontal inequity was estimated through concentration indexes, and inequity by both education and income was estimated as risk ratios through conventional regression.ResultsWe found no overall pro-rich or pro-educated socioeconomic gradient in needs-adjusted utilisation of general practitioner or inpatient care. However, we found overall pro-rich and pro-educated inequity in utilisation of both private medical specialists and hospital outpatient care. For these services there were large differences in levels of inequity between younger and older men and women.ConclusionIn contrast with recent studies from Norway, we found pro-rich and pro-educated social inequalities in utilisation of hospital outpatient services and not only private medical specialists. Utilisation of general practitioner and inpatient services, which have low access threshold or are free of charge, we found to be equitable.

Adolescent Health and High School Dropout: A Prospective Cohort Study of 9000 Norwegian Adolescents (The Young-HUNT)

Background High school dropout is of major concern in the western world. Our aims were to estimate the risk of school dropout in adolescents following chronic somatic disease, somatic symptoms, psychological distress, concentration difficulties, insomnia or overweight and to assess to which extent the family contributes to the association between health and school dropout. Methods A population of 8950 school-attending adolescents (13–21 years) rated their health in the Young-HUNT 1 Study (90% response rate) in 1995–1997. High school dropout or completion, was defined with the Norwegian National Education Database in the calendar year the participant turned 24 years old. Parental socioeconomic status was defined by using linkages to the National Education Database, the National Insurance Administration and the HUNT2 Survey. We used logistic regression to estimate odds ratios and risk differences of high school dropout, both in the whole population and among siblings within families differentially exposed to health problems. Results All explored health dimensions were strongly associated with high school dropout. In models adjusted for parental socioeconomic status, the risk differences of school dropout according to health exposures varied between 3.6% (95% CI 1.7 to 5.5) for having ≥1 somatic disease versus none and 11.7% (6.3 to 17.0) for being obese versus normal weight. The results from the analyses comparing differentially exposed siblings, confirmed these results with the exception of weaker associations for somatic diseases and psychological distress. School dropout was strongly clustered within families (family level conditional intraclass correlation 0.42). Conclusions Adolescent health problems are markers for high school dropout, independent of parental socioeconomic status. Although school dropout it strongly related to family-level factors, also siblings with poor health have reduced opportunity to complete high school compared to healthy siblings. Public health policy should focus on ensuring young people with poor health the best attainable education.

High school dropout and long-term sickness and disability in young adulthood: a prospective propensity score stratified cohort study (the Young-HUNT study)

BackgroundHigh school dropout and long-term sickness absence/disability pension in young adulthood are strongly associated. We investigated whether common risk factors in adolescence may confound this association.MethodsData from 6612 school-attending adolescents (13–20 years old) participating in the Norwegian Young-HUNT1 Survey (1995–1997) was linked to long-term sickness absence or disability pension from age 24–29 years old, recorded in the Norwegian Labour and Welfare Organisation registers (1998–2008). We used logistic regression to estimate risk differences of sickness or disability for school dropouts versus completers, adjusting for health, health-related behaviours, psychosocial factors, school problems, and parental socioeconomic position. In addition, we stratified the regression models of sickness and disability following dropout across the quintiles of the propensity score for high school dropout.ResultsThe crude absolute risk difference for long-term sickness or disability for a school dropout compared to a completer was 0.21% or 21% points (95% confidence interval (CI), 17 to 24). The adjusted risk difference was reduced to 15% points (95% CI, 12 to 19). Overall, high school dropout increased the risk for sickness or disability regardless of the risk factor level present for high school dropout.ConclusionHigh school dropouts have a strongly increased risk for sickness and disability in young adulthood across all quintiles of the propensity score for dropout, i.e. independent of own health, family and socioeconomic factors in adolescence. These findings reveal the importance of early prevention of dropout where possible, combined with increased attention to labour market integration and targeted support for those who fail to complete school.

Socioeconomic inequalities in dental services utilisation in a Norwegian county: The third Nord-Trøndelag Health Survey

Aim: To assess the level of socioeconomic inequity in dental care utilisation in Norway and enable comparison with recent international comparative studies. Methods: We studied dental care utilisation among 17,136 men and 21,414 women in the third Nord-Trøndelag Health Survey (2006–08). Respondents aged 20 years and above were included in the study, and analyses were also performed within subgroups of age and gender (20–39, 40–59, and ≥60 years). Income-related horizontal inequity was estimated by means of concentration indices. Education-related inequity was estimated as relative risks. Results: We found consistent pro-rich income inequity among men and women of all ages. The level of income inequity was highest among men and women ≥60 years, and in this group the income gradient was steepest between the poorest and the middle quintiles. Pro-educated inequity was found exclusively among men and women ≥60 years. General attendance was high (77%). Conclusion: The overall level of income-related inequity in dental services utilisation was low compared to other European countries as reported in two recent international studies of socioeconomic inequalities in dental care utilisation. Pro-rich and pro-educated inequity is a public health challenge mainly in the older part of the population.

Educational inequalities in disability pensioning − the impact of illness and occupational, psychosocial, and behavioural factors: The Nord-Trøndelag Health Study (HUNT)

Aims: Socioeconomic inequalities in disability pensioning are well established, but we know little about the causes. The main aim of this study was to disentangle educational inequalities in disability pensioning in Norwegian women and men. Methods: The baseline data consisted of 32,948 participants in the Norwegian Nord-Trøndelag Health Study (1995–97), 25–66 years old, without disability pension, and in paid work. Additional analyses were made for housewives and unemployed/laid-off persons. Information on the occurrence of disability pension was obtained from the National Insurance Administration database up to 2008. Data analyses were performed using Cox regression. Results: We found considerable educational inequalities in disability pensioning, and the incidence proportion by 2008 was higher in women (25–49 years 11%, 50–66 years 30%) than men (25–49 years 6%, 50–66 years 24%). Long-standing limiting illness and occupational, psychosocial, and behavioural factors were not sufficient to explain the educational inequalities: young men with primary education had a hazard ratio of 3.1 (95% CI 2.3–4.3) compared to young men with tertiary education. The corresponding numbers for young women were 2.7 (2.1–3.1). We found small educational inequalities in the oldest women in paid work and no inequalities in the oldest unemployed/laid-off women and housewives. Conclusions: Illness and occupational, psychosocial, and behavioural factors explained some of the educational inequalities in disability pensioning. However, considerable inequalities remain after accounting for these factors. The higher incidence of disability pensioning in women than men and the small or non-existing educational inequalities in the oldest women calls for a gender perspective in future research.

Socio-economic inequalities in Norwegian health care utilization over 3 decades: the HUNT Study

BACKGROUND The aim of this study was to investigate socio-economic inequalities in health care utilization from the 1980s and through the last 3 decades in a Norwegian county population. METHODS Altogether, 166 758 observations of 97 251 individuals during surveys in 1984-86 (83% eligible responses), 1995-97 (51% eligible responses) and 2006-08 (50% eligible responses) of the total population of adults (≥ 20 years) from Nord-Trøndelag county in Norway were included. Health care utilization was measured as at least one visit to general practitioner (GP), hospital outpatient services and inpatient care in the past year. Socio-economy was measured by both education and income and rescaled to measure relative indexes of inequality (RII). Relative and absolute inequalities were estimated from multilevel logistic regression. Estimates were adjusted for age, sex, municipality size and self-reported health. RESULTS GP utilization was higher among individuals with higher education in 1984-86. Among men the RII was 0.54 (CI: 0.48-0.62), and among women RII was 0.67 (CI: 0.58-0.77). In 2006-08, the corresponding RII was 1.31 (CI: 1.13-1.52) for men and 1.00 (CI: 0.85-1.18) for women, indicating higher or equal GP utilization among those with lower education, respectively. The corresponding RIIs for outpatient consultations were 0.58 (CI: 0.49-0.68) for men and 0.40 (CI: 0.34-0.46) for women in 1984-86, and 0.53 (CI: 0.46-0.62) for men and 0.47 (CI: 0.41-0.53) for women in 2006-08. CONCLUSION Through the last 3 decades, the previous socio-economic differences in GP utilization have diminished. Despite this, highly educated people were more prone to utilize hospital outpatient consultations throughout the period 1984-2008.

Reading and writing difficulties in adolescence and later risk of welfare dependence. A ten year follow-up, the HUNT Study, Norway

BackgroundWelfare dependence and low work participation among young people have raised concern in many European countries. Reading and writing difficulties (RWD) might make young people vulnerable to work integration problems and welfare dependence through negative influences on education and health. Our main objective of this study was to examine if RWD in adolescence affected the risk of welfare dependence in young adulthood.MethodsBaseline information on self-reported RWD, health and family was obtained for 8950 school-attending adolescents in Nord-Trøndelag County, Norway, participating in the Young-HUNT1 survey, 1995-97. All individuals were linked to biological parents to identify siblings and parental education from national registers. Welfare dependence was assessed by the reception of social benefits (medical and economic) from the national social insurance database (1998-2007). Only long-term benefits (> 180 days) were included.ResultsThe adolescents who reported RWD at baseline were more likely to receive medical or social benefits during follow-up compared with those who did not report RWD. In girls with RWD, the adjusted 5-year risk (at age 24 to 28) for receiving medical benefits was 0.20 (95% confidence interval 0.14-0.26), compared with 0.11 (0.09-0.12) in girls without RWD. In boys the corresponding risks were 0.13 (0.09-0.17) and 0.08 (0.07-0.09).ConclusionsThe associations between RWD in adolescence and welfare dependence later in life suggest that increased attention should be paid to these problems when discussing the public health aspects of work integration, since there might be a potential for prevention.
