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.

Country specific associations between social contact and mental health: evidence from civil servant studies across Great Britain, Japan and Finland.

OBJECTIVES: Little is known about which component, such as social contact of social networks is associated with mental health or whether such an association can be observed across countries. This study examined whether the association between frequent social contact and mental health differs by composition (relatives or friends) and whether the associations are similar across three occupational cohorts from Great Britain, Japan, and Finland. STUDY DESIGN: Cross-sectional analysis of data from three prospective cohort studies. METHODS: Participants were civil servants of a prospective cohort study based in London (Men: n = 4519; Women: n = 1756), in the West Coast of Japan (Men: n = 2571; Women: n = 1102), and in Helsinki, Finland (Men: n = 1181; Women: n = 5633); we included the information on study variables which is complete. Mental health function was the study outcome, indicated by the total score from the Mental Health Component on the Short Form Health Survey36. Participants reported frequencies of contacts with their relatives or friends via a questionnaire. Age, marital status, and occupational position were treated as confounders in this study. RESULTS: Findings from multiple regression showed that the associations between social contact and mental health function were different depending on country of origin and gender. Among British or Japanese men, frequent contact with both friends and relatives was positively associated with their mental health function, while only social contact with friends was significantly associated with mental health of Finnish men. In women, the patterns of the associations between social contact and mental health were more distinctive: friends for Great Britain, relatives for Japan, and friends and relatives for Finland. These significant associations were independent of the confounders. CONCLUSIONS: Social contact was related to mental health of working people; however, culture and gender are likely to be tapped into.

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.

Socioeconomic inequalities in cause-specific mortality after disability retirement due to different diseases.

AIMS: Socioeconomic inequalities in both disability retirement and mortality are large. The aim of this study was to examine socioeconomic differences in cause-specific mortality after disability retirement due to different diseases. METHODS: We used administrative register data from various sources linked together by Statistics Finland and included an 11% sample of the Finnish population between the years 1987 and 2007. The data also include an 80% oversample of the deceased during the follow-up. The study included men and women aged 30-64 years at baseline and those who turned 30 during the follow-up. We used Cox regression analysis to examine socioeconomic differences in mortality after disability retirement. RESULTS: Socioeconomic differences in mortality after disability retirement were smaller than in the population in general. However, manual workers had a higher risk of mortality than upper non-manual employees after disability retirement due to mental disorders and cardiovascular diseases, and among men also diseases of the nervous system. After all-cause disability retirement, manual workers ran a higher risk of cardiovascular and alcohol-related death. However, among men who retired due to mental disorders or cardiovascular diseases, differences in social class were found for all causes of death examined. For women, an opposite socioeconomic gradient in mortality after disability retirement from neoplasms was found. Conclusions: The disability retirement process leads to smaller socioeconomic differences in mortality compared with those generally found in the population. This suggests that the disability retirement system is likely to accurately identify chronic health problems with regard to socioeconomic status.

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.

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.

Work-family conflicts and health behaviors among British, Finnish, and Japanese employees.

BACKGROUND: Work-family conflicts are associated with poor health. However, work-family conflicts and health behaviors have been little studied. PURPOSE: This study examined the associations of conflicts between paid work and family life with unhealthy behaviors among British, Finnish, and Japanese employees. METHOD: Data were derived from postal questionnaire surveys among 40 to 60 years old employees from three cohorts, the British Whitehall II Study (n = 3,397), the Finnish Helsinki Health Study (n = 4,958), and the Japanese Civil Servants Study (n = 2,901). Outcomes were current smoking, heavy drinking, physical inactivity, and unhealthy food habits. Work-family conflicts were measured with eight items. Age, marital status, and occupational class were adjusted for in logistic regression analyses. RESULTS: Work-family conflicts had few and inconsistent associations with unhealthy behaviors in all three cohorts. In the Finnish cohort, strong work-family conflicts were associated with current smoking among men. Women with strong conflicts had more often unhealthy food habits and were more often heavy drinkers than women with weaker conflicts. Likewise, British women with strong work-family conflicts were more often heavy drinkers. CONCLUSION: Although work-family conflicts were fairly prevalent in the examined cohorts, these conflicts had but few associations with the studied key health behaviors.

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.

The effect of pain on sickness absence among middle-aged municipal employees.

OBJECTIVES: To study the effects of pain on sickness absence, taking into account physical and psychosocial work load and socio-economic position. METHODS: Data consisted of City of Helsinki personnel register data on sickness absence and a cross-sectional questionnaire survey which was carried out among employees of the City of Helsinki who reached the age of 40, 45, 50, 55 or 60 years during the years 2000-2002 (n = 8960, response rate 67%). Data sets were combined for those who gave permission for such linkage (78%). The main statistical method was negative binomial regression analysis. RESULTS: The burden of pain on sickness absence was dependent on the duration of absence: the longer the duration, the higher the burden. Self-certified absence was equally predicted by acute and chronic pain, but medically certified absence was more clearly predicted by chronic pain. Adjustments for a range of work load factors and socio-economic position showed that pain was a relatively independent determinant of subsequent sickness absence, but in particular physical work load and socio-economic position explained a small proportion of the association. Overall, pain accounted for 13% of self-certified absence among women and 8% among men. Corresponding figures were 23% and 25% for medically certified 4-14-day sickness absence and 37% and 30% for absence of over 2 weeks. CONCLUSIONS: The burden of pain on medically certified sickness absence is considerable. Prevention of pain problems is vital for reducing sickness absence rates.

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.

Negative life events and stability of sense of coherence: a five-year follow-up study of Finnish women and men.

A strong sense of coherence (SOC) is found to be associated with good mental health. This study investigated (1) whether negative life events affect level of SOC, (2) whether initial level of SOC modifies the effect of negative life events on SOC, and (3) whether stability of SOC differs between genders. The data were derived from the 15-year Health and Social Support study (N= 17,271). Ordinary linear regression analysis was used. Negative life events decreased the level of SOC among both genders irrespective of the timing of the event. The more recent the life event, the lower the SOC. A strong SOC in 1998 did not protect SOC from declining during follow-up. Specific gender differences were not discovered. SOC was related to negative changes in people's environment. Initially strong SOC was not more stable than initially mediocre or weak SOC. Men and women reacted quite similarly to negative life events.

Applying an equity lens to tobacco-control policies and their uptake in six Western-European countries.

We identified policies that may be effective in reducing smoking among socioeconomically disadvantaged groups, and examined trends in their level of application between 1985 and 2000 in six western-European countries (Sweden, Finland, the United Kingdom, the Netherlands, Germany, and Spain). We located studies from literature searches in major databases, and acquired policy data from international data banks and questionnaires distributed to tobacco policy organisations/researchers. Advertising bans, smoking bans in workplaces, removing barriers to smoking cessation therapies, and increasing the cost of cigarettes have the potential to reduce socioeconomic inequalities in smoking. Between 1985 and 2000, tobacco control policies in most countries have become more targeted to decrease the smoking behaviour of low-socioeconomic groups. Despite this, many national tobacco-control strategies in western-European countries still fall short of a comprehensive policy approach to addressing smoking inequalities.
