Unintentional injury mortality -The role of criminal offending. A Swedish longitudinal population based study.

The aim was to investigate life course criminality in relation to unintentional injury mortality and other causes of death among 49,398 male Swedish conscripts aged 18-20 years in 1969/70 and a follow-up through 35 years. All subjects completed two questionnaires at the time of conscription concerning family, social, behavioural risk factors including alcohol and drug use. The impacts of committed crimes, alcohol and drug use and other risk factors were estimated using proportional hazard ratios (HRs) from Cox regression analyses. Many adolescent offences entailed a nearly six-fold higher injury mortality risk (HR = 5.64) and a four-fold higher risk (HR = 3.93) for all other causes vs. no convictions. In multivariate analyses, adolescent criminality was still found to be significantly associated with time to unintentional injury mortality, while criminality limited to adulthood had a moderately higher risk for all other causes of deaths. Individuals with both adolescence and adult criminality showed elevated mortality from especially unintentional injury (HR = 5.06), with the hazards remaining elevated, even after adjustment for other behavioural risk factors. Men with behavioural risk factors including alcohol and/or drug misuse in combination with frequent criminality seem to be a vulnerable group of both unintentional and other causes of deaths.

On how to increase safety innovations.

In this action research study, we show by several cases that a synthetic innovation style in combination with an entrepreneurial culture might increase innovations for safety. Rational decisions and early product specifications were replaced by a natural selection of ideas in an acting reality to have the most fitted ideas among the actors. The forthcoming ideas actually ruled the development of the process and the business set-up like in an entrepreneurial culture. With financial support from the Swedish research funds, Vinnova and SBUF, a laboratory for both research and innovation was implemented at the Karolinska Institutet. The laboratory emanated from an initiative of Professor Leif Svanström in developing a multidisciplinary collaboration on design and consumer safety. In this review, we present our promising findings.

The research group, the conference programme and academic training in safety promotion - a report of the activities at Karolinska Institutet, Sweden.

The research group was established in 1967 at Lund University and moved to Karolinska Institutet in 1980. Work began with epidemiological studies of all injuries in the local community in support of various experimental local interventions. An important element was the creation of 'surveillance systems' in healthcare. The work resulted in the establishment of a WHO Collaborating Centre and an international safety-building programme called 'Safe Communities'. In parallel, training at both master's and doctoral level and the building of a conference programme were embarked upon. The research group consists of three sections. Specific efforts are being made by some countries to address their own injury problems.

Estimating drowning deaths in Northern Iran using capture-recapture method.

BACKGROUND: Descriptive epidemiological study has shown that drowning is a problem health in low and middle income countries. To analyze records of drowning deaths from two injury registry systems, to ascertain a true estimate of drowning-mortality, it can help to follow up drowning prevention policy. METHODS: This study uses capture-recapture methods to arrive at a more accurate estimate of the number of drowning events occurring over a one-year period in Guilan and Mazandran Provinces, in northern Iran. Records from the Iran's Forensic Medical System and Death Registry System were compared, using five matching approaches based on various combinations of the following variables: gender, place of drowning, date of death, victim age, name, region of residence, and/or place of residence. RESULTS: The results revealed that the estimated number of drowning cases in the study population is much higher than official figures, ranging from 5.26 to 8.25 per 100,000 residents compared to the national figure of 4.5 per 100,000. The completeness of Death Registry System records for drowning was 70% of corrected estimates while the completeness of records from Forensic Medicine was 54.4%. CONCLUSION: We conclude that the use of capture-recapture methodology may provide better accuracy in measuring drowning events. This method may also help reduce bias in the estimate of incidence rates and comparison of different populations.

Early predictors of injury mortality among Swedish conscripts: a 35-year cohort study.

Injuries represent an important cause of mortality among young adults. We studied the associations between adolescents' family, psychological, behavioural and drug-related risk factors in relation to unintentional injury death. A population-based cohort of 49,411 Swedish conscripts aged 18-20 years was followed for 35 years. The end-point of study was injury death up to 2004. The relationship between two family, four psychological and eight behavioural risk factors and injury death were analysed with Cox proportional hazards analyses and χ(2) tests. Among 485 unintentional injury deaths, 40% occurred in subjects aged 25 years or under. The incidence per 1000 person years was 0.29 (95% CI, 0.26-0.31) and the mean age of death was 33 years. Problem drinking at both adolescent and adulthood was more strongly associated with injury death (HR=5.40) than illicit drug use (HR=2.70) even after adjusted for behavioural risk factors: (HR=3.43) and (HR=1.75), respectively. Adolescent risk factors such as contact with police and juvenile authorities, low emotional control, conduct problems at school and low social maturity were significant predictors of injury death in multivariate analyses. Young adults with social, behavioural and psychological problems and especially alcohol and drug use at both adolescent and adulthood have a high mortality rate due to road traffic injuries and all kind of injuries. Early identification of vulnerable groups of adolescents with psychological and behavioural problems including alcohol and drug use at local levels could make a difference.

Contraception, reproductive health and pregnancy outcomes among women exposed to intimate partner violence in Nigeria.

OBJECTIVES: To examine the association between reproductive health practices/outcomes and exposure to intimate partner violence (IPV) among women in Nigeria. More specifically, the association between IPV and use of contraception; miscarriages,induced abortions, stillbirths, and infant mortality; and having many children, was assessed. METHODS: Data on studied variables were retrieved from the Demographic and Health Surveys of Nigeria 2008, a nationally representative sample of 33,385 women of reproductive age. IPV was defined as exposure to physical, sexual or emotional abuse. The association between contraception use, pregnancy outcomes and infant mortality, and exposure to IPV was assessed using the chi-square test for unadjusted analyses. To control for potential confounding, socio-demographic variables were adjusted for using multiple logistic regression. RESULTS: Compared with women not exposed to IPV, those who were, exhibited a higher likelihood of using modern forms of contraception; having a history of miscarriages, induced abortions, stillbirths, or infant mortality; and having many children. The aforementioned observations still stood after adjustment for potential confounders (e.g., demographic and socioeconomic factors). CONCLUSION: Though causal inference cannot be drawn due to the cross-sectional design, the study has important implications for incorporation of IPV detection and management in initiatives aimed at improving women's reproductive health.

The relationship between intimate partner violence and maternal practices to correct child behavior: a study on women in Egypt.

BACKGROUND: This paper scrutinizes the association between maternal practices to correct child behavior and the mothers' exposure to and attitudes towards intimate partner violence (IPV). METHODS: Nationally representative data comprising 14 016 married women were retrieved from the Egyptian Demographic and Health Survey, 2005. Data on practices used to correct child behavior, exposure to IPV, attitudes towards IPV were our primary interest. Data were analyzed using Chi-square test and logistic regression. RESULTS: The majority of the mothers reported use of violent methods, like shouting (90.6%), striking (69.1%) and slapping (39.3%) to correct child behavior. Seven percent of the mothers used only the explanation option. Exposure to physical IPV and tolerant attitudes towards IPV were associated with an augmented risk of using violent methods (shouting, striking or slapping) to correct child behavior. On the other hand non-tolerant attitudes towards IPV were associated with increased likelihood of sole use of the explanation method. CONCLUSIONS: We thus recommend the implementation of local parental education programs focusing on communicative skills to reduce IPV and related child abuse.

Women's attitudes towards discontinuation of female genital mutilation in Egypt.

BACKGROUND: To examine women's attitude towards discontinuation of female genital mutilation (FGM) in association with their access to information, knowledge of health effects and cultural beliefs concerning FGM in Egypt. METHODS: A cross-sectional study of 9159 women, using data from the household survey in Egypt by Demographic and Health survey 2003. A comprehensive questionnaire covering attitudes towards FGM, demographics, and access to information was used. Chi-square analysis and logistic regression were applied to investigate how demographics, level of education, access to information, knowledge of health consequences and cultural beliefs influence women's attitudes towards FGM. RESULTS: Among the demographic variables, discontinuation of FGM was independently associated with urban residency and post-secondary education. Moreover, women who were informed by the media, and those who had attended community meetings, church, or mosque where FGM was discussed, as well as women who were aware of the negative health consequences of FGM, were more likely to support discontinuation of FGM. By contrast, women with positive cultural conceptions of FGM were less likely to favor its discontinuation. CONCLUSIONS: Public education and information dissemination aiming to change current cultural notions favoring FGM practice - through community and religious leaders, and radio and television programs - may play an important role in modifying women's attitudes towards FGM. These findings have some implications for intervention and policy.

Wife abuse in rural Bangladesh.

Intimate partner violence (IPV) is a global public health and gender problem, especially in low-income countries. The study focused on verbal abuse, physical abuse and abuse by restricting food provision to wives by their husbands by victim and perpetrator characteristics, emphasizing the socioeconomic context of rural Bangladesh. Using a cross-sectional household survey of 4411 randomly selected married women of reproductive age, the study found that a majority of the respondents are exposed to verbal abuse (79%), while 41% are exposed to physical abuse. A small proportion (5%) of the women had suffered food-related abuse. Risk factors observed were age of the wife, illiteracy (of both victims and perpetrators), alcohol misuse, dowry management, husband's monetary greed involving parents-in-law, and wife's suspicions concerning husband's extramarital affairs. Well-established risk factors for wife abuse, along with dowry and husband's monetary greed, have a relatively high prevalence in rural Bangladesh.

Factors associated with disclosure of intimate partner violence among women in Lagos, Nigeria.

BACKGROUND: Though the prevalence of Intimate Partner Violence (IPV) remains high in less developed countries, data suggest that these figures may represent an underestimation considering that many women are unwilling to disclose abuse. This paper aims to determine women's willingness to report abuse, factors determining willingness to disclose IPV, and to whom such disclosure is made. METHODS: A total of 911 women visiting reproductive health facility responded to the questionnaire, and the collected data was analyzed using multivariate analysis. RESULTS: About 54% (n=443) of the participating women reported that would not disclose IPV. Among those willing to disclose abuse, 68% (n=221) would opt to disclose to close relatives in contrast to 32% (n=103) who would disclose to some form of institutions (i.e. religious leaders, law enforcement officers). Ethnicity, woman's own use of alcohol and autonomy in decision making such as having a say on household purchases, money use and visitation, independently predicted willingness to disclose IPV. CONCLUSIONS: The role of family is still important in the Nigeria context and the implications for research and intervention are discussed.

Leadership, organization and health at work: a case study of a Swedish industrial company.

The application of knowledge on organization and leadership is important for the promotion of health at workplace. The purpose of this article is to analyse the leadership and organization, including the organizational culture, of a Swedish industrial company in relation to the health of the employees. The leadership in this company has been oriented towards developing and actively promoting a culture and a structure of organization where the employees have a high degree of control over their work situation. According to the employees, this means extensive possibilities for personal development and responsibility, as well as good companionship, which makes them feel well at work. This is also supported by the low sickness rate of the company. The results indicate that the leadership and organization of this company may have been conducive to the health of the employees interviewed. However, the culture of personal responsibility and the structure of self-managed teams seemed to suit only those who were able to manage the demands of the company and adapt to that kind of organization. Therefore, the findings indicate that the specific context of the technology, the environment and the professional level of the employees need to be taken into consideration when analysing the relation between leadership, organization and health at work.

Social inequalities in intimate partner violence: a study of women in Kenya.

This study examines social inequalities in intimate partner violence (IPV) among women of reproductive age in Kenya. A sample comprising 3,696 women was retrieved from the Kenyan Demographic and Health Survey of 2003. The study design was cross-sectional. Chi-square tests and logistic regression were used to analyze the data. Results indicated that while high education among women reduced the risk of IPV exposure, both being employed and having a higher education/occupational status than her partner increased a woman's vulnerability to IPV. Age differences between the partners, illiteracy, and lack of autonomy and access to information increased the likelihood of IPV. Finally, being in polygamous relationships was associated with IPV exposure. The findings indicate demographic, social, and structural differences in exposure to IPV with important implications for interventions.

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.

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.

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.

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.

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.

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.
