Why does Sweden have the lowest childhood injury mortality in the world? The roles of architecture and public pre-school services.

Of interest is how some countries have achieved a profound reduction of child injury mortality. Still little is reported on the impact of a combination of urban planning, social welfare development and safety measures. We therefore present trends in childhood (0-14 years) injury mortality in Sweden 1966-2001 and discuss the factors behind any reductions observed. Annual total and cause-specific injury mortality rates were computed by age subgroups and gender. Trend analyses were performed with year as independent and mortality rate as dependent variable. A piecewise linear function was fitted to the annual mortality rates. Data were categorized into five 7-year intervals. In total, there were 5264 deaths due to injury in the study population during the period 1966-2001, of which 3368 (64%) were of boys and 1896 (36%) girls. The most frequent external cause of death was transport injury (48%), drowning (14%), homicide (5.8%), fire (5%), and fall (2.7%). About 66% (n=3474) of deaths occurred during the first half of the study period (1966-1981) with an average incidence rate of mortality 13.0 compared to 5.6 per 100,000 inhabitants during the second half of the period (1982-2001). For total injuries, there was a statistically significant decrease in mortality among all subgroups of children in both sexes. The slopes are greater among the younger children (0-4, 5-9 years) than the older ones (10-14 years). Several factors behind this strong decline of childhood injury mortality of interest to evaluate are (i) the implementation of the functionalist architectural style including transport separation, legislation and safety in cars; (ii) the expansion of public child day-care centers including more organized leisure activities; (iii) the establishment of long-term nationwide mandatory program for swim training among school children and (iv) local child-safety programs considering differences in exposure to risk between urban and rural areas.

A small fraction of patients with repetitive injuries account for a large portion of medical costs.

BACKGROUND: The phenomenon of repetitive injuries has been judged to be of limited importance in the public health context. A study was therefore initiated in order to analyse all types of single and repetitive injuries using a longitudinal approach. METHODS: Hospital care, medical costs and risk factors were examined for single and repetitive severe injuries. A cross-sectional survey with a 12-year follow-up was performed. Questionnaire information from a survey of a random sample of the adult population 20-89 years old in 1984 in Stockholm County were linked to the Swedish national inpatient and cause-of-death register up to 1996, inclusive. RESULTS: During the study period 13% of males and 15% of females were hospitalized or deceased as a result of injuries. Persons with three or more injuries comprise 19% of the injuries, but account for 63% of the total number of days of hospital care and medical costs. Injuries related to falls were most common among patients requiring hospital care. Factors such as high age, living alone, stroke earlier, and use of hypnotics and sedatives were especially associated with repetitive injuries. The risk factors for single and repetitive injuries covariate, but the size of the risk is overrepresented for stroke, drugs, self-reported injuries and living alone for two or more injuries. CONCLUSION: These results indicate that subjects with repetitive injuries, and with the observed risk factors for such injuries, should be given extra attention, both in policy and prevention, but also in integrated treatment programmes.

Effects of macroeconomic trends on social security spending due to sickness and disability.

OBJECTIVES: We analyzed the relationship between macroeconomic conditions, measured as unemployment rate and social security spending, from 4 social security schemes and total spending due to sickness and disability. METHODS: We obtained aggregated panel data from 13 Organization for Economic Cooperation and Development member countries for 1980-1996. We used regression analysis and fixed effect models to examine spending on sickness benefits, disability pensions, occupational-injury benefits, survivor's pensions, and total spending. RESULTS: A decline in unemployment increased sickness benefits spending and reduced disability pension spending. These effects reversed direction after 4 years of unemployment. Inclusion of mortality rate as an additional variable in the analysis did not affect the findings. CONCLUSIONS: Macroeconomic conditions influence some reimbursements from social security schemes but not total spending.

Sunbed use among Swedish adolescents in the 1990s: a decline with an unchanged relationship to health risk behaviors.

AIMS: Sunbed use is common among adolescents, and may give an increment to UV exposure and an overall skin cancer risk comparable to that of the sun. Sunbed use was studied among 15- to 19-year-old adolescents in Stockholm County. METHODS: Data from two questionnaire surveys (1252 respondents in 1993, and 2950 respondents in 1999, survey tool partly revised) were analysed. By stepwise binary logistic regression the occurrence of sunbed use was assessed and analysed versus sunbed erythema, skin type, outdoor tanning, sunscreen use and smoking. RESULTS: Sunbed use declined between the surveys. In 1993, 70% of females, and 44% of males used sunbeds; in 1999, these were 45% and 19% respectively. Sunbeds were used against user recommendations. Of the sunbed users in 1993, 45% and 43% reported sunbed erythema; in 1999, 29% and 19% did so. Sunbed erythema, though related to sun sensitivity, occurred in all skin types. In both surveys, sunbed use was positively related to moderately sensitive skin type (females), outdoor tanning, and smoking (females). Smoking was a strong predictor for sunbed use among females in both surveys. CONCLUSIONS: Even though different survey tools were used, and in spite of a decline in sunbed use, sunbed erythema was still common, and the relation to other health risk behaviour remained. Further research on sunbed use and its role in the aggregation of health risk behaviours in vulnerable ages is warranted, particularly its relation to outdoor tanning and smoking. A national and international harmonization of survey tools is also recommended for improved comparability.

Work load and work hours in relation to disturbed sleep and fatigue in a large representative sample.

OBJECTIVE: To study the relation between work and background factors on the one hand and disturbed sleep and fatigue on the other. METHOD: A representative national sample of 58,115 individuals was selected at regular intervals over a period of 20 years and interviewed on issues related to work and health. The data were subjected to a multiple logistic regression analysis. RESULTS: The number of cases was 18,828 (32.8%) for fatigue and 7347 (12.8%) for disturbed sleep. For disturbed sleep, the significant predictors became: female gender, age above 49 years, present illness, hectic work, physically strenuous work, and shift work. For fatigue, the significant predictors became female gender, age below 49 years, high socioeconomic status, present illness, hectic work, overtime work, and physically strenuous work. CONCLUSION: Work stress, shift work, and physical workload interfere with sleep and are related to fatigue.

Association between use of sedatives or hypnotics, alcohol consumption, or other risk factors and a single injurious fall or multiple injurious falls: a longitudinal general population study.

In this study, we investigated the association between risk factors, including use of sedatives or hypnotics or alcohol consumption, and injurious falls leading to hospitalization or death among 4023 subjects (1828 men and 2195 women) aged 20-89 years in Stockholm County, Sweden. Questionnaire data obtained from the 1984-1985 Stockholm Health of the Population Study (SHPS) were linked to official data registers on hospitalization and mortality. Of the 4023 subjects, 330 (121 men and 209 women) had been treated for or died of injurious falls during the 12-year follow-up period. High age was significantly associated with injurious falls among both men and women. Multivariate analyses showed that women who had used sedatives or hypnotics during the 2 weeks before an injurious fall were at increased risk [relative risk of 1.83 (95% confidence interval, 1.10-3.06)] for two or more injurious falls, but not for a single fall accident. High alcohol consumption and earlier self-reported injurious falls were significantly associated with injurious falls for women younger than 60 years of age and with earlier self-reported falls and living alone for men in the same age category. Among older women (>60 years of age), high alcohol consumption and use of sedatives or hypnotics were significantly associated with injurious falls, whereas living alone and earlier self-reported accidents were significant predictors for men in the same age category. These results support a cautious prescribing policy for sedatives and hypnotics, as well as an awareness of high alcohol consumption and its association with injurious falls.

Redistributive effects of the Swedish social insurance system.

BACKGROUND: Four principles are used to distribute payments via the Swedish social-insurance system in cases of temporary or permanent illness and death. This paper studies the redistributive effects on income of these four principles. METHODS: The analysis is based on aggregate social-insurance data from the 25 municipalities that comprise Stockholm County in Sweden. For nine different types of social-insurance payments based on the four principles, the degree of income redistribution is measured according to concentration indexes and differences between Gini coefficients with social-insurance payments excluded and included. RESULTS: The concentration indexes for payments from the nine social-insurance schemes in total is -0.0469. The Gini coefficient falls from 0.0437 excluding insurance payments (i.e. for income only from gainful work, IGW) to 0.0379 when including insurance payments with income from gainful work (IGW + TP). That is, the Gini coefficient is 15% lower when insurance payments are included. Decomposition by payment shows that the largest redistribution effect on income inequality is made by disability pension. CONCLUSION: Municipalities with low average income are favoured by the Swedish social-insurance system. Payment principles can be ranked according to their redistributive capacity: mix of compensating-lost-income and flat-rate, compensating-lost-income, means-testing, flat-rate, and need-based respectively. The nine social-insurance schemes contribute very differently to income redistribution. Disability pension and sickness allowance contribute most to income redistribution and reducing income inequality.
