BACKGROUND Previous trend studies have shown large increases in hip fracture incidence rates among the elderly. International research, however, suggests a levelling off, or decline, of hip fracture incidence rates, although for Sweden this remains to be studied. METHODS Data were obtained regarding hip fractures among individuals 65 years and above from(More)
The purposes of this study are to provide an estimation of the incidence of transport injuries in a defined local community in Nicaragua by using the capture-recapture method, and to compare results using this method when data at different levels of severity are utilized. Two sources of injury data were used to monitor injuries: hospital data (inpatient and(More)
Cross-sectional studies have produced clear inverted U-shaped curves between injury mortality and economic development; yet, this does not mean that single countries will necessarily follow similar curves as they grow richer over time. This study was conducted to examine whether previous cross-sectional findings can be verified using a longitudinal(More)
PROBLEM Suicide is a dominating, although hidden, safety problem on Swedish railroads. The aim of this paper is to describe the epidemiology of fatal train-person collisions as a basis for systems-oriented prevention. METHOD Data on collision circumstances were collected from narrative reports at the Swedish National Rail Administration. RESULTS The(More)
OBJECTIVES The aim of the present study was to investigate the cause-specific patterns of unintentional injury mortality among 15-44-year-olds in various income-based country groups, and to analyze which specific causes contribute the most to the unintentional injury mortality in each country group. MATERIALS AND METHODS Cross-sectional data on the five(More)
At the international level, evidence supports the position that regardless of whether a country is industrialized or less developed, vulnerable populations living in poor social conditions are at disproportionate risk of injury. The Aboriginal population of Canada is one such vulnerable population. In addition to poor social conditions and marginalization(More)
BACKGROUND Injury is recognized as an important public health problem not only in high-income countries, but also in low- and middle-income countries. Other studies have shown inverse association between economic development and unintentional injury mortality (UIM) among children and young adults. In this study we aimed to examine the association between(More)
AIMS This study examined the association between homicide rates and GNP per capita (as a measure of economic development) among all age- and sex-specific groups in 53 countries. METHODS Cross-sectional data on homicide rates by age- and sex- specific groups were obtained for 53 countries from World Health Statistics Annual 1996. The association between(More)
Although injuries constitute a major public health problem worldwide, the magnitude and nature of this problem is difficult to establish in low-income settings due to the lack of valid and representative data. In Nicaragua, several parallel studies have been carried out attempting to assess levels and patterns of injury using various sources of information.(More)
