Use of primary health care services and mortality in older patients with type 2 diabetes with or without comorbidities.

OBJECTIVE: This study aimed to examine primary health care (PHC) service utilization and mortality in older patients with type 2 diabetes (T2D) with or without comorbidities. DESIGN AND SETTING: A cohort study in PHC in the city of Vantaa, Finland. Follow-up period was set between the years 2011 and 2018. SUBJECTS: PHC patients aged 60 years or more with a T2D were included. MAIN OUTCOME MEASURES: Service utilization was defined as the number of face-to-face appointments and telephone contacts between a patient and general practitioner (GP) or nurse. The presence of comorbidities was defined using the Charlson Comorbidity Index (CCI). Mortality was assessed using hazard ratio (HR) and standardized mortality ratio (SMR). RESULTS: In total, 11,020 patients were included and followed for 71,596 person years. Mean age of the women and men in the beginning of follow-up were 71 and 69 years, respectively. The patients in the study cohort had a mean of eight appointments per person year to the GPs or nurses. Patients with T2D with comorbidities had more appointments than patients with T2D without comorbidities (incidence rate ratio (IRR) 1.44 [95% CI 1.39-1.49]). Increase in the number of all appointments reduced mortality in patients with T2D with and without comorbidities. Between patients with T2D with comorbidities and patients with T2D without comorbidities, the age and sex adjusted HR for death was 1.50 (95% CI 1.39-1.62). The SMR was higher in patients with T2D with comorbidities (1.83 [95% CI 1.74-1.92]) than in patients with T2D without comorbidities (0.91 [95% CI 0.86-0.96]). CONCLUSIONS: In older patients with T2D, the presence of comorbidities was associated with increased use of PHC services and increased mortality. Increase in the number of appointments was associated with reduced mortality in patients with T2D with or without comorbidities.Key PointsIn older patients with T2D, it has not been studied whether and to what extend multimorbidity affects use of PHC services and mortality.The presence of comorbidities according to the Charlson Comorbidity Index (CCI) was associated with increased use of PHC services.The number of appointments to GPs or nurses was associated with reduced mortality in patients with T2D with or without comorbidities according to the CCI.

Physical working conditions and subsequent sickness absence: a record linkage follow-up study among 19-39-year-old municipal employees.

PURPOSE: Physical work exposures are associated with sickness absence among older employees. We aimed to examine if they similarly contribute to all-cause sickness absence during early and mid-careers. METHODS: We used questionnaire data on physical work exposures linked to register data on sickness absence from 3542 municipal employees aged 19-39 years. Follow-up for the number of sickness absence days was 12 months. Exposures to physical workload, occupational environmental hazards, and sedentary work were divided into quartiles. In addition, duration of daily exposure to heavy work was included. Negative binomial regression models were used. RESULTS: Higher exposure to physical workload or hazardous exposures was associated with a higher number of sickness absence days. The age and gender adjusted rate ratios for sickness absence days among the participants whose exposure to physical workload was in the highest exposure quartile were 2.1 (95% CI 1.8‒2.5) compared with those whose exposure was in the lowest quartile. In addition, rate ratios for sickness absence days among participants who reported that they do heavy physical work 1.1‒2.0 h, 2.1‒4.0 h or over 4 h daily were 1.6 (1.3‒1.9), 1.5 (1.3‒1.8) and 1.7 (1.5‒2.1), respectively, compared with those who reported not doing physical work. Further adjustment for lifestyle factors or health characteristics attenuated the associations only slightly. CONCLUSION: Exposure to physically demanding work is associated with a higher number of sickness absence days among municipal employees below 40 years of age. Physical working conditions should be considered when aiming to support later work ability.

Intergenerational social mobility and body mass index trajectories - A follow-up study from Finland.

Evidence remains unclear on how intergenerational social mobility is associated with body mass index (BMI) and its long-term changes. Our study identified BMI trajectories from middle to older age by intergenerational social mobility groups and stratified the analyses by gender and two birth cohorts (birth years 1940‒1947 and 1950-1962). We used questionnaire-based cohort data that consists of four survey phases: 2000-2002, 2007, 2012, and 2017. In Phase 1, participants were 40-60-year-old employees of the City of Helsinki, Finland. Our analytical sample consisted of 6,971 women and 1,752 men. Intergenerational social mobility was constructed based on self-reported parental and own education-both divided into high and low-yielding four groups: stable high socioeconomic position (SEP) (high-high), upward social mobility (low-high), downward social mobility (high-low), and stable low SEP (low-low). BMI was calculated from self-reported height and weight from all four phases. Using mixed-effects linear regression, we found increasing BMI trajectories in all four social mobility groups until the age of 65. Women and men with stable high SEP had lower BMI trajectories compared to those with stable low SEP. In the younger birth cohort, women with upward social mobility had a lower BMI trajectory than women with stable low SEP. Additionally, women and men with downward social mobility had higher BMI trajectories than those with stable high SEP. In the older birth cohort, however, the BMI trajectories of upward and downward social mobility groups were somewhat similar and settled between the BMI trajectories of stable high and stable low SEP groups. Our results indicate that the associations between intergenerational social mobility and BMI may depend on gender and birth cohort. Nevertheless, to reduce socioeconomic inequalities in unhealthy weight gain, obesity prevention actions that focus on people who are likely to remain in low SEP might be worthwhile.

Grocery purchase data in the study of alcohol use - A validity study.

BACKGROUND: Alcohol use epidemiology is facing challenges as survey response rates decline. In addition, population surveys fail to capture a large proportion of alcohol consumed and are expensive to conduct. This study aims to aid in complementing traditional epidemiological methods by validate grocery purchase data in the research on population alcohol use. METHODS: The LoCard study subjects were loyalty card holders of a grocery retail co-operative, which possessed more than 45 % market share in Finland. One third of those who consented to the analyses of their grocery purchases were presented a questionnaire including a Food Frequency Questionnaire on the web; N = 11,818 responded. The relationship between beer purchase frequency and self-reported beer drinking frequency was studied for association and agreement in different subgroups using crosstabulations and Poisson regression modeling. RESULTS: The association between beer purchase frequency and self-reported beer drinking frequency was good (Gamma = .556). The agreement between beer purchase frequency and drinking frequency was only fair (Kappa = .189). Limiting the data to those single adult households that reported making at least 61 % of their grocery purchases from this grocery retailer and collapsing the frequency categories to three instead of six increased the agreement to good (Kappa = .463). CONCLUSIONS: Information on beer purchase frequency from the loyalty card database can be used to rank people according to their drinking frequency and to estimate beer drinking frequency with fair to good accuracy, depending on what share of grocery purchases they make from the grocery retailer in question.

Changes in leisure-time physical activity and physical and mental health functioning: a follow-up study.

Functioning will be an increasingly important issue in Finland over the coming decades as the proportion of the population aged 65 and older is growing significantly. However, the associations between changes in physical activity and subsequent health functioning are poorly understood. The aim of this study was to examine how changes in physical activity relate to concurrent and prospective levels of health functioning. Cohort data from the Helsinki Health Study were used. Phase 1 (n = 8960, response rate 67%, 80% women) was conducted among 40- to 60-year-old employees of the City of Helsinki in 2000-2002, phase 2 in 2007 (n = 7332, response rate 83%), and phase 3 in 2012 (n = 6814, response rate 79%). Linear mixed models were used as the main statistical method. Increasing physical activity was associated with higher concurrent and prospective levels of physical health functioning, whereas decreasing activity was associated with lower levels of physical health functioning. The associations were stronger with physical than with mental health functioning. Promoting physical activity among aging people may help to maintain their level of health functioning.

Common mental disorders and cause-specific disability retirement.

OBJECTIVES: Common mental disorders are prevalent among employees and may cause work disability. We aimed to examine the association between common mental disorders and disability retirement, with an emphasis on the severity of disorders and diagnostic causes for retirement. METHODS: Our data were derived from the Helsinki Health Study cohort on the staff of the City of Helsinki, Finland. The baseline mail surveys were made in 2000-2002 among employees reaching ages 40, 45, 50, 55 and 60 in each year (n=8960, response rate 67%, 80% women). Disability retirement events from national registers (n=628) were followed up by the end of 2010 and linked to the baseline data. After exclusions, the number of participants was 6525. Common mental disorders were measured by the General Health Questionnaire 12-item version (GHQ-12). Covariates at baseline included sociodemographic, work-related and health-related factors. Hazard ratios (HR) and 95% CIs were calculated using Cox proportional hazards models. RESULTS: Common mental disorders showed a graded association with disability retirement. For disability retirement due to any diagnostic cause, the fully adjusted HR for the GHQ-12 score 7-12 was 2.16, 95% CI 1.63 to 2.85. For disability retirement due to mental disorders the corresponding HR was 7.46, 95% CI 4.46 to 12.49. For disability retirement due to musculoskeletal diseases, the association was weaker and did not survive all adjustments. CONCLUSIONS: Common mental disorders are an important antecedent of disability retirement in general and due to mental disorders in particular. Successful measures against common mental disorders may prevent disability retirement due to mental disorders.

Conflicts between work and family life and subsequent sleep problems among employees from Finland, Britain, and Japan.

PURPOSE: Research on the association between family-to-work and work-to-family conflicts and sleep problems is sparse and mostly cross-sectional. We examined these associations prospectively in three occupational cohorts. METHODS: Data were derived from the Finnish Helsinki Health Study (n = 3,881), the British Whitehall II Study (n = 3,998), and the Japanese Civil Servants Study (n = 1,834). Sleep problems were assessed using the Jenkins sleep questionnaire in the Finnish and British cohorts and the Pittsburgh Sleep Quality Index in the Japanese cohort. Family-to-work and work-to-family conflicts measured whether family life interfered with work or vice versa. Age, baseline sleep problems, job strain, and self-rated health were adjusted for in logistic regression analyses. RESULTS: Adjusted for age and baseline sleep, strong family-to-work conflicts were associated with subsequent sleep problems among Finnish women (OR, 1.33 (95 % CI, 1.02-1.73)) and Japanese employees of both sexes (OR, 7.61 (95 % CI, 1.01-57.2) for women; OR, 1.97 (95 % CI, 1.06-3.66) for men). Strong work-to-family conflicts were associated with subsequent sleep problems in British, Finnish, and Japanese women (OR, 2.36 (95 % CI, 1.42-3.93), 1.62 (95 % CI, 1.20-2.18), and 5.35 (95 % CI, 1.00-28.55), respectively) adjusted for age and baseline sleep problems. In men, this association was seen only in the British cohort (OR, 2.02 (95 % CI, 1.42-2.88)). Adjustments for job strain and self-rated health produced no significant attenuation of these associations. CONCLUSION: Family-to-work and work-to-family conflicts predicted subsequent sleep problems among the majority of employees in three occupational cohorts.

Work-family conflicts and subsequent sleep medication among women and men: a longitudinal registry linkage study.

Work and family are two key domains of life among working populations. Conflicts between paid work and family life can be detrimental to sleep and other health-related outcomes. This study examined longitudinally the influence of work-family conflicts on subsequent sleep medication. Questionnaire data were derived from the Helsinki Health Study mail surveys in 2001-2002 (2929 women, 793 men) of employees aged 40-60 years. Data concerning sleep medication were derived from the Finnish Social Insurance Institution's registers covering all prescribed medication from 1995 to 2007. Four items measured whether job responsibilities interfered with family life (work to family conflicts), and four items measured whether family responsibilities interfered with work (family to work conflicts). Cox proportional hazard models were fitted, adjusting for age, sleep medication five years before baseline, as well as various family- and work-related covariates. During a five-year follow-up, 17% of women and 10% of men had at least one purchase of prescribed sleep medication. Among women, family to work conflicts were associated with sleep medication over the following 5 years after adjustment for age and prior medication. The association remained largely unaffected after adjusting for family-related and work-related covariates. Work to family conflicts were also associated with subsequent sleep medication after adjustment for age and prior medication. The association attenuated after adjustment for work-related factors. No associations could be confirmed among men. Thus reasons for men's sleep medication likely emerge outside their work and family lives. Concerning individual items, strain-based ones showed stronger associations with sleep medication than more concrete time-based items. In conclusion, in particular family to work conflicts, but also work to family conflicts, are clear determinants of women's sleep medication.

Risk factors of chronic neck pain: a prospective study among middle-aged employees.

OBJECTIVE: To study the associations of sociodemographic factors, working conditions, lifestyle and previous pain in the spine with new onset chronic neck pain (NP). METHODS: The participants were municipal employees free of chronic NP at baseline, aged 40, 45, 50, 55 or 60 years (n = 5277, 80% women). Self-reported data on occupational class, working conditions, body mass index, smoking, exercise, mental well-being, sleep problems, NP and low back pain (LBP) were obtained from baseline questionnaire surveys in 2000-2002. The question on chronic NP was repeated in a follow-up in 2007. Logistic regression analysis was used. RESULTS: The incidence of chronic NP was 15% in women and 9% in men. In multivariable analysis among women, acute NP [odds ratio (OR) 3.8, 95% confidence interval (CI) 2.9-5.1], chronic LBP (1.6, 1.2-2.2), reporting current workplace bullying (OR 1.6, 95% CI 1.1-2.4), earlier bullying at the present workplace (1.6, 1.2-2.0), and earlier bullying in another workplace (1.8, 1.3-2.4), frequent sleep problems (1.5, 1.2-2.0), overweight (1.2, 1.0-1.5), and obesity (1.4, 1.1-1.8) predicted chronic NP at follow-up. Men with acute NP (2.3, 1.4-3.8), chronic LBP (2.3, 1.2-4.3), manual occupational class (1.8, 1.1-3.1) and high work-related emotional exhaustion (1.9, 1.1-3.3) at baseline had an increased risk of new onset chronic NP. CONCLUSIONS: We found potentially modifiable predictors of chronic NP among employees: workplace bullying, sleep problems, and high body mass index in women, and work-related emotional exhaustion in men. In both genders, previous acute NP and chronic LBP were predictive of chronic NP.

Explaining educational differences in leisure-time physical activity in Europe: the contribution of work-related factors.

Although educational differences in leisure-time physical activity (LTPA) exist across Europe, the independent effect of educational level on leisure-time physical activity has rarely been explored. This study examines the relative contribution of occupational class, employment status, and educational level to LTPA across 12 European countries. The data were obtained from 12 European health surveys conducted at the turn of the century and identified in the EUROTHINE project. All information was self-reported. Logistic regression was applied and relative inequality index (RII) was calculated. Analyses were limited to those in the prime working-age (age 30-59; total N=137,646) men and women. In all 12 European countries, LTPA was more common in the high-educated than in the low-educated. The association between education and LTPA remained mostly unchanged after adjusting for marital status, urbanization, and self-rated health. After further adjusting for occupational class and employment status, the educational differences in LTPA were only slightly attenuated. An inverse association was found between educational level and LTPA across almost all 12 European countries. Occupational class and employment status had only a modest effect on educational differences in LTPA in most of the examined countries, suggesting that education remains an important predictor of LTPA.

Sleep problems and major weight gain: a follow-up study.

OBJECTIVE: To examine the associations between sleep problems and major weight gain during a 5- to 7-year follow-up among middle-aged women and men. METHODS: The Helsinki Health Study prospective cohort baseline survey data from 2000 to 2002 (n = 8960, response rate 67%) among 40- to 60-year-old municipal employees and follow-up survey data from 2007 (n = 7332, response rate 83%) were used. Logistic regression analysis was used to examine the association between the four-item Jenkins Sleep Questionnaire and major weight gain of 5 kg or more over a 5- to 7-year follow-up. RESULTS: Half of the participants reported at least occasional sleep problems, whereas 13% of women and 17% of men reported no such problems at baseline. The frequency of sleep problems varied by item. Frequent sleep problems were reported by 20% of women and 17% of men. Major weight gain was reported by 25% of women and 24% of men. Trouble falling asleep (odds ratio (OR) 1.65; 95% confidence interval (CI) 1.22, 2.22), waking up several times per night (OR 1.49; 95% CI 1.22, 1.81) and trouble staying asleep (OR 1.41; 95% CI 1.13, 1.75) were associated with major weight gain during the follow-up in women but not in men. In contrast, waking up tired was unassociated with weight gain. The summary measure of the four items was also associated with weight gain in women. Adjusting for baseline body mass index, physical health, health behaviour, marital status, education, work arrangements and sleep duration had only minor effects on the above associations. Adjusting for common mental disorders at baseline, the associations were attenuated but remained for trouble falling asleep, waking up several times per night and trouble staying asleep. Occasional sleep problems were also associated with weight gain. CONCLUSION: Sleep problems likely contribute to weight gain. To prevent major weight gain and obesity, sleep problems need to be taken into account.

The association of income with fresh fruit and vegetable consumption at different levels of education.

This study examined whether the association of household income with fresh fruit and vegetable consumption varies by the level of education. Data were derived from mail surveys carried out during 2000-2002 among 40- to 60-year-old employees of the City of Helsinki (n=8960, response rate 67%). Education was categorized into three levels, and the household income was divided into quartiles weighted by household size. The outcome was consumption of fresh fruit and vegetables at least twice a day (58% among women and 33% among men). Beta-binomial regression analysis was used. Among women, higher income resulted in equally higher consumption of fruit and vegetables at all educational levels, that is, similar among those with low, intermediate and high education. Among men, the pattern was otherwise similar; however, men with intermediate education differed from those with low education. We conclude that the absolute cost of healthy food is likely to have a role across all income groups.

The impact of physical activity on sickness absence.

The aim of this study was to examine whether the volume and intensity of physical activity are associated with subsequent sickness absence spells of different lengths, and how much of these associations can be explained by socioeconomic position, body mass index (BMI) and physical health functioning. Baseline data were collected by questionnaire surveys in 2000-2002 among 40-60-year-old employees of Helsinki City (n=6465, 79% women). Sickness absence data were derived from the employer's registers (mean follow-up time 3.9 years). Associations of physical activity with shorter (< or =14 days) and longer (>14 days) sickness absence spells were examined, using Poisson's regression analysis. The volume of physical activity was weakly and somewhat inconsistently associated with sickness absence. However, men and women who were vigorously active systematically had reduced risk of sickness absence, whereas the same volume of moderately intensive physical activity did not reduce the risk of sickness absence. Adjusting for BMI and in particular physical health functioning attenuated these associations, after which the associations lost statistical significance. The results suggest that vigorous physical activity is associated with sickness absence and may contribute to better work ability.

Explaining occupational class differences in sickness absence: results from middle-aged municipal employees.

OBJECTIVES: Low socioeconomic position is consistently associated with higher rates of sickness absence. We aimed to examine whether working conditions, health-related behaviours and family-related factors explain occupational class differences in medically certified sickness absence. METHODS: The study included 5470 women and 1464 men employees of the City of Helsinki, surveyed in 2000-2002. These data were prospectively linked to sickness absence records until the end of 2005, providing a mean follow-up time of 3.9 years. Poisson regression was used to examine the occurrence of medically certified sickness absence episodes lasting 4 days or more. RESULTS: Medically certified sickness absence was roughly three times more common among manual workers than among managers and professionals in both women and men. Physical working conditions were the strongest explanatory factors for occupational class differences in sickness absence, followed by smoking and relative weight. Work arrangements and family-related factors had very small effects only. The effects of psychosocial working conditions were heterogeneous: job control narrowed occupational class differences in sickness absence while mental strain and job demands tended to widened them. Overall, the findings were quite similar in women and men. CONCLUSIONS: Physical working conditions provided strongest explanations for occupational class differences in sickness absence. Smoking and relative weight, which are well-known determinants of health, also explained part of the excess sickness absence in lower occupational classes. Applying tailored work arrangements to employees on sick leave, reducing physically heavy working conditions and promoting healthy behaviours provide potential routes to narrow occupational class differences in sickness absence.

Health-related behaviours and sickness absence from work.

OBJECTIVES: To compare associations of health-related behaviours with self-certified and medically confirmed sickness absence, and to examine whether these associations can be explained by psychosocial and physical working conditions and occupational social class. METHODS: The study included 5470 female and 1464 male employees of the City of Helsinki surveyed in 2000-2002. These data were linked to sickness absence records until the end of 2005, providing a mean follow-up time of 3.9 years. Poisson regression analysis was used to examine associations of smoking, alcohol use, physical activity, dietary habits and relative weight (body mass index) with self-certified (1-3 days) and medically confirmed (> or =4 days) absence spells. Population attributable fractions (PAFs) were calculated to quantify the sickness absence burden related to the behaviours. RESULTS: Smoking and high relative weight were most strongly associated with sickness absence, while the associations of other studied health-related behaviours were weaker. The associations were stronger for medically confirmed sickness absence spells for which heavy smoking and obesity more than doubled the risk of sickness absence in men and nearly doubled it in women. Adjusting for psychosocial working conditions had little or no effect on the associations. Physical working conditions and social class somewhat attenuated the associations, especially for smoking and relative weight. In self-certified sickness absence the PAF for smoking (16.4 in men, 10.3 in women) was largest, while in medically confirmed absence relative weight had the largest PAF (23.5 in men, 15.0 in women). CONCLUSIONS: Health-related behaviours, smoking and high relative weight in particular, were associated with subsequent sickness absence independently of psychosocial and physical working conditions and social class. Decreasing smoking and relative weight is likely to provide important gains in work ability and reduce sickness absence.

Job strain and symptoms of angina pectoris among British and Finnish middle-aged employees.

BACKGROUND: High job strain has been linked with cardiovascular outcomes. This study aimed to examine whether job strain is associated with angina pectoris symptoms among British and Finnish non-manual employees. METHODS: Postal questionnaire survey data among 40-60-year-old employees of the British Whitehall II Study (n = 4551, 27% women) and the Finnish Helsinki Health Study (n = 7605, 83% women) cohort were analysed. Angina pectoris symptoms were the outcome in logistic regression analysis. Karasek's job strain was examined. Models were adjusted first for age, second for occupational class and finally for smoking, heavy drinking, physical inactivity, unhealthy food habits and obesity. RESULTS: Angina pectoris symptoms were reported by 5% of women and 3% of men in Britain, and by 6% of women and 4% of men in Finland. High job strain was associated with angina pectoris symptoms among men in Britain (OR 2.08; CI 95% 1.07 to 4.02) and women in Finland (OR 1.90; CI 95% 1.36 to 2.63) independent of age, occupational class, and behavioural risk factors. However, similar associations between job strain and angina pectoris symptoms were not observed among men in Finland or women in Britain. CONCLUSION: The results yielded partial support for the association between job strain and angina pectoris symptoms across national contexts.

Economic difficulties and common mental disorders among Finnish and British white-collar employees: the contribution of social and behavioural factors.

BACKGROUND: In addition to conventional indicators of socioeconomic position, material conditions such as economic difficulties are associated with mental health. However, there has been little investigation of these associations. This study aims to examine the association of current economic difficulties with common mental disorders (CMD) and the contribution of social and behavioural factors to this association in two cohorts of Finnish and British white-collar employees. METHODS: Comparable survey data from the Finnish Helsinki Health Study and the British Whitehall II Study were used. CMD were measured with the GHQ-12. Inequality indices from logistic regression analysis were used to examine the association between current economic difficulties and CMD, and the contribution of other past and present socioeconomic circumstances, health behaviours, living arrangements and work-family conflicts to this association. Inequality indices show the average change in ill health for each step up in the level of economic difficulties. Analyses were conducted separately for men and women. RESULTS: Clear associations between current economic difficulties and CMD were found. Adjusting for work-family conflicts attenuated the associations. Adjusting for indicators of past and present socioeconomic circumstances, health behaviours and living arrangements had generally negligible effects. The results were very similar among both sexes in the two cohorts. CONCLUSIONS: Conflicts between work and family contribute to the association between economic difficulties and CMD in both Finland and Britain. Supporting people to cope not only with everyday economic difficulties but also with work-family conflicts may be important for reducing inequalities in mental health.

Trends in socioeconomic differences in Finnish perinatal health 1991-2006.

BACKGROUND: Socioeconomic differences in perinatal health decreased in Finland in the late 1990s. Whether the decreasing socioeconomic differences in perinatal health observed in Finland in the late 1990s have continued in 2000-6 was studied. METHODS: The data were based on 965 443 births and 931 285 singletons recorded between 1991 and 2006 in the Finnish Medical Birth Register. Information on socioeconomic position was based on maternal occupation. Perinatal health was measured with six different indicators. RESULTS: The proportions of preterm, low birthweight and SGA (small-for-gestational-age) births remained stable during the study period, but decreased for LGA (large-for-gestational-age) births and perinatal death. After adjustment for maternal background variables, the socioeconomic differences in preterm and low-birthweight births decreased in the late 1990s and remained low thereafter. In 2003-6, blue-collar workers had a 14% (95% CI 7% to 22%) higher risk for preterm birth and a 25% (95% CI 16% to 34%) higher risk for low birthweight than upper white-collar workers. For SGA, the socioeconomic differences remained unchanged, and the excess risk for blue-collar workers was 44% (95% CI 31% to 58%) in 2003-6. For LGA, the socioeconomic differences increased, and the highest excess risks were obtained among lower white-collar (23%, 95% CI 15% to 33%) and blue-collar workers (24%, 95% CI 14% to 36%). The differences in perinatal mortality decreased until the late 1990s, but increased thereafter. In 2003-6, lower white-collar and blue-collar workers had the highest excess risks: 46% (95% CI 20% to 77%) and 44% (95% CI 13% to 83%), respectively. CONCLUSIONS: The trends in social inequality in perinatal health outcomes were diverging by indicator. The positive trend on diminishing socioeconomic differences found in the 1990s seems to have come to an end.

Home ownership and mortality: a register-based follow-up study of 300,000 Finns.

BACKGROUND: This study examined whether living in rented housing is associated with increased all-cause and cause-specific mortality, and whether the association between home ownership and mortality can be explained by household income, occupational class, and educational level. METHODS: A random sample including every seventh Finn aged 40-80 years at the end of 1997 (N = 308 291) was derived from the population register of Finland. The sample was followed up for mortality until the end of 2003 during which time there were 22,721 deaths. RESULTS: The hazard ratio for all-cause mortality among renters compared with owner-occupiers was 2.06 (95% CI 1.98 to 2.14) in men and 1.73 (1.65 to 1.81) in women. Adjusting for household income, occupational class, and educational level attenuated the excess mortality among renters by 30% in men and 19% in women. The effect of income was larger among the under 65 year olds than those aged 65 years or over. Excess mortality among renters was particularly high for alcohol-related diseases, respiratory diseases, lung cancer, as well as endocrine, metabolic and nutritional diseases, and infections. CONCLUSIONS: Renters had higher mortality than owner-occupiers even after adjusting for household income, occupational class, and educational level. Home ownership may indicate material living standards and cumulative wealth that cannot sufficiently be captured by conventional socioeconomic indicators. Analysing home ownership may thus increase understanding of the factors producing inequalities in health.

Explanations for gender differences in sickness absence: evidence from middle-aged municipal employees from Finland.

OBJECTIVES: To examine gender differences in sickness absence spells of various lengths and to explain these differences by health status, working conditions and family-related factors. METHODS: The study included 5470 female and 1464 male employees of the City of Helsinki surveyed at baseline in 2000-2. These survey data were linked to the employer's sickness absence records until the end of 2005, providing a mean follow-up time of 3.9 years. Explanations for gender differences in self-certified (1-3 days) and medically confirmed absence spells of various lengths (4 days or more, more than 2 weeks, and more than 60 days) were examined using Poisson regression. RESULTS: Women had 46% higher risk for self-certified sickness absence than men. In medically confirmed spells there was 34% female excess which gradually weakened with lengthening absence, and no differences were observed in spells longer than 60 days. Adjusting for physical functioning and self-reported diagnosed diseases clearly attenuated gender differences in sickness absence spells shorter than two weeks and fully explained them in longer absence spells. Physical work demands explained female excess in medically confirmed absence spells of all lengths, as did work fatigue in spells longer than two weeks. Psychosocial working conditions and family-related factors did not affect the gender differences. Physical health problems, physical work demands and work fatigue were somewhat more prevalent in women than in men, but their impact on sickness absence was similar in both genders. CONCLUSIONS: The overall gender differences in sickness absence are due to relatively short absence spells being more common among women. In longer sickness absence spells the female excess is mainly explained by heavier burden of ill-health and to a lesser extent by higher physical work demands among women. The authors found no support for greater vulnerability to health- and work-related problems among women as reasons for sickness absence.
