Socio-economic differences in self-reported insomnia and stress in Finland from 1979 to 2002: a population-based repeated cross-sectional survey.

ABSTRACT:

Background

Over the decades, global public health efforts have sought to reduce socio-economic health differences, including differences in mental health. Only a few studies have examined changes in socio-economic differences in psychological symptoms over time. The aim of this study was to assess trends in socio-economic differences in self-reported insomnia and stress over a 24-year time period in Finland.

Methods

The data source is a repeated cross-sectional survey "Health Behaviour and Health among the Finnish Adult Population" (AVTK), from the years 1979 to 2002, divided into five study periods. Indicators for socio-economic status included employment status from the survey, and educational level and household income from the Statistics Finland register data. We studied the age group of 25-64 years (N?=?70115; average annual response rate 75%). Outcome measures were single questions of self-reported insomnia and stress.

Results

The overall prevalence of insomnia was 18-19% and that of stress 16-19%. Compared to the first study period, 1979-1982, the prevalence of stress increased until study period 1993-1997. The prevalence of insomnia increased during the last study period, 1998-2002. Respondents who were unemployed or had retired early reported more insomnia and stress over time among both men and women. Lower education was associated with more insomnia especially among men; and conversely, with less stress among both sexes. Compared to the highest household income level, those in the intermediate levels of income had less stress whereas those in the lowest income levels had more stress among both sexes. Income level differences in insomnia were less consistent. In general, socio-economic differences in self-reported insomnia and stress fluctuated some, but did not change substantially over the study period 1979-2002.

Conclusions

Self-reported insomnia and stress were more common during later study periods. The socio-economic differences in insomnia and stress have remained fairly stable over a 24-year time period. However, some of the associations in socio-economic differences were curvilinear and converse. Future studies are needed to explore the complex socio-economic gradients, especially in stress.

Project description:The prevalence of sarcoidosis is known to be high in the Nordic countries. There are no recent research data on the incidence or prevalence of sarcoidosis in Finland. Our aim was to investigate the epidemiology of sarcoidosis in Finland through a retrospective registry-based study. We made an information request to the Hilmo database on patients who had been treated in Finnish specialised care with a main diagnosis related to sarcoidosis. Data were requested for the period 1 January-31 December for the years 2002, 2012 and 2022. In addition, we examined the age and gender distribution and regional differences in these variables between the five university hospital districts covering the whole of Finland. The incidence of sarcoidosis was 17‒19/100 000/year throughout the follow-up period. The prevalence of sarcoidosis in the ≥18-year-old population had risen from 85/100 000 in 2002-106/100 000 in 2022. There were considerable differences between university hospital districts: The highest prevalence rate was 170/100 000 in the Tampere University Hospital district in 2022, which was twice as high as in the Helsinki University Hospital district (84/100 000). The proportion of pulmonary sarcoidosis in all sarcoidosis cases decreased from 62% to 45% while the proportion of multiorgan sarcoidosis (D86.8) increased from 11% to 34%. The incidence of sarcoidosis was 15/100 000 and the prevalence was 82/100 000 in the age groups of ≥60 years in 2002. In 2022, the incidence in this same age group had risen to 20/100 000 and the prevalence to 109/100 000. In the ≥60-year-old population, the proportion of D86.8 increased from 11% to 35%. Sarcoidosis was a more common disease in Finland than in previous studies. Multiorgan sarcoidosis among the elderly has increased over the past 20 years. This might be explained by changes in environmental factors associated with sarcoidosis. Significant regional differences in prevalence might be partly explained by familial clustering.

Project description:BackgroundLow socio-economic position is associated with consumption of lower quality diets, which may be partly explained by the cost of healthier diets. Therefore, we aimed to investigate the mediating role of dietary costs in the association between educational level and diet quality.MethodsWe used cross-sectional data from Dutch older adults (N = 9399) in the EPIC-NL cohort. Participants provided information about their own and their partners' highest attained educational level (as proxy for socio-economic position). Dietary behavior was assessed using a food frequency questionnaire from which we derived two diet-quality scores, including the Dutch Healthy Diet index 2015 (DHD15-index) and the Dietary Approaches to Stop Hypertension (DASH) diet. Dietary cost estimates were based on food price data from food stores, and linked to reported consumption of food items. Multiple regression analyses and bootstrapping were used examine the mediating role of dietary cost in the association between educational level and diet quality.ResultsMean age of participants was 70 (SD: 10) years and 77% were women. Dietary costs significantly mediated the association between educational level and diet quality, except for high versus middle individual educational level and the DHD15-index. Depending on the dietary and educational indicator, dietary costs explained between 2 and 7% of the association between educational level and diet quality. Furthermore, associations were found to be modified by sex and age. For the DHD15-index, mediation effects were only present in females and adults older than 65 years, and for the DASH diet mediation effects were only present in females and strongest amongst adults older than 65 years compared to adults younger than 65 years.ConclusionDietary costs seems to play a modest role in explaining educational differences in diet quality in an older Dutch population. Further research is needed to investigate which other factors may explain SEP differences in diet quality.
