Death from choking is the fourth most common cause of unintentional-injury mortality, but little data are published on causes or locations of these episodes. These deaths typically are peaked at the extremes of age, with young children and the elderly having the greatest rate of fatal choking. Our objective was to characterize the causes of fatal airway obstruction in adults. The San Diego County Medical Examiner's database was searched for deaths attributed to choking in decedents 18 years and older during the 10-year period from 1994 to 2004. Data were abstracted regarding the underlying medical conditions, items choked on, location of the choking, and treatments involved in the individual cases. We found 133 victims who died from choking, with 14% having using alcohol or other sedatives and 55% having a documented neurological deficit or anatomic difficulty with swallowing. The most common specified food objects that victims choked on were meat products, and 45% occurred at home, followed by 26% at supervised facilities, and 14% at restaurants. Of the 19 choking episodes occurring in restaurants, only one employee was documented to attempt a resuscitative effort. Most victims who choked to death had an underlying neurological deficit, and occurred at home or supervised facilities appear to have an appropriate initial-response intervention. 相似文献

Motor vehicle rollover crashes result in complex occupant kinematics with the potential for severe injury. Five cases of fatal asphyxia in occupants suspended from their safety belt upside down after a rollover crash are presented. These fatalities accounted for 13.5% of all motor vehicle related asphyxia deaths in San Diego County over a 10-year period. This study supports previous research noting that incapacitation due to other injuries, alcohol, or obesity may be associated with fatal positional asphyxia due to inversion during rollovers. Safety belts are proven to prevent serious injury in motor vehicle crashes and should always be worn. However, redesign of the buckle could be considered to permit easier release by an occupant. We also suggest that pre-existing heart disease may contribute to the possibility of a fatal asphyxia outcome. Although this is a rare cause of motor vehicle related death, our results suggest that these are potentially preventable deaths. 相似文献

This study examines the effects of changes in family structure on children's economic well‐being. An initial shift‐share analysis indicates that, had the proportion of children living in female‐headed families remained constant since 1970, the 1998 child poverty rate would have been 4.4 percentage points lower than its actual 1998 level of 18.3 percent. The March 1999 Current Population Survey is then used to conduct a second analysis in which marriages are simulated between single mothers and demographically similar, unrelated males. The microsimulation analysis addresses some of the shortcomings of the shift‐share approach by making it possible to account for the possibility of a shortage of marriageable men, to control for unobservable differences between married men and women and their unmarried counterparts, and to measure directly the effects of increases in marriage on the economic well‐being of children. Results from the microsimulation analysis suggest that, had the proportion of children living in female‐headed families remained constant since 1970, the child poverty rate would have been 3.4 percentage points lower than its actual 1998 level. Among children whose mother participated in a simulated marriage, the poverty rate would have fallen by almost two‐thirds. © 2002 by the Association for Public Policy Analysis and Management. 相似文献

While the majority of studies examining defensive weapon ownership identify variables related to ownership, these studies suffer from several methodological problems. Inclusion of sporting influences into a measure of defensive weapon ownership and errors in attribution of demographic variables weaken the results in many of these studies. In order to overcome these obstacles, only those respondents claiming to live alone were included in this analysis, and respondents were asked specifically if they had purchased a weapon for self-protection. Separate probit equations were estimated for males and females to assess differential indicators for men and women. Results indicate that although having a prior victimization was a significant positive indicator of self-help for men, women did not display similar relationships. Variables dealing with neighborhood characteristics, such as the percent of single parent households with children aged twelve through twenty and perceptions that crime is increasing in the neighborhood, were significant predictors of defensive weapon ownership for women. 相似文献
