Avoidable mortality in Lithuania: 1991-199 compared with 1970-1990

This paper assesses the changes in avoidable mortality in Lithuania in 1991-1999 compared with 1970-1990. Causes of death were disaggregated into causes most amenable to treatment and those amenable to prevention. Trends in age-standardised death rates were calculated. In 1970-1990, avoidable causes of death accounted for 26.3% of all deaths. By 1991-1999 this figure had decreased slightly to 24.6%. At the same time, age-standardised death rates from avoidable causes increased by 8%, from 118.1 per 100000 in 1970-1990 to 127.9 in 1991-1999. Avoidable mortality among men was considerably higher than for women in both periods. There was considerable fluctuation in both treatable and preventable mortality during the 1990s, reflecting diversity in trends in different causes of death. Increases occurred in death rates from tuberculosis, cervical cancer and liver cirrhosis and, immediately after independence, also in hypertensive and cerebrovascular diseases and, among men, lung cancer, followed by subsequent declines. Deaths from chronic rheumatic heart disease, asthma and other respiratory diseases, appendicitis, abdominal hernia, cholelithiasis and maternal mortality consistently declined. In conclusion, avoidable mortality declined as a proportion of total mortality in Lithuania during 1991-1999 compared with 1970-1990. This reflected the combined impact of an initial rise in death rates from treatable and, to a lesser extent, preventable causes, followed by subsequent declines. While this indicates some success in the development of medical care, it emphasises the need for more effective public health policies directed at the major determinants of health.     

Homicide surveillance--United States, 1979-1988.

From 1979 through 1988, 217,578 homicides occurred in the United States, an average of greater than 21,000 per year. Homicide rates during this 10-year period were about 1.5 times higher than the rates during the 1950s. The national homicide rate of 10.7/100,000 in 1980 was the highest ever recorded. Homicide occurs disproportionately among young adults. Among the 15- to 34-year age group, homicide is the fourth most common cause of death among white females, the third most common cause among white males, and the most common cause among both black females and black males. In 1988, nearly two-thirds (61%) of homicide victims were killed with a firearm, 75% of these with a handgun. More than half (52%) of homicide victims were killed by a family member or acquaintance, and about one-third (35%) of homicides stemmed from a conflict not associated with another felony. The homicide mortality rate among young black males 15-24 years of age has risen 54% since 1985. Ninety-nine percent of the increase was accounted for by homicides in which the victim was killed with a firearm. The surveillance data summarized in this report should assist public health practitioners, researchers, and policymakers in addressing this important public health problem.     

Homicide victims in New Orleans: recent trends

Data are presented on 694 criminal homicide victims killed in the city of New Orleans during four years; 1979, 1982, 1985, and 1986. The homicide rate for black males was 6.5 times higher than that for white males for the years studied. Over 70% of victims were killed by handguns. When victims were assigned to one of five socioeconomic strata, homicide rates for blacks exceeded those for whites by a factor of at least 2.5 times for each socioeconomic stratum. White victims were more likely than were black victims to be legally intoxicated at the time of death, but black victims were nearly four times more likely to have illicit drugs other than alcohol detected. During the time period investigated, there was a marked decrease in the number of victims with pentazocine and tripelennamine ("Ts and blues") detected and an abrupt increase in the number of victims with detectable phencyclidine and cocaine levels. Further studies are needed to investigate risk factors for homicide victimization so that effective intervention strategies can be employed.     

Violence and fear of violence in East and West Germany

The purpose of this research was to assess the effect of major social changes in Germany since 1989 on mortality due to intentional injury. Mechanisms and types of fatal intentional injury in East and West Germany between 1970 and 1995 were determined from death certificates and compared with judicial data on violent crime convictions and recent public survey data on citizen fear of crime. The number of homicides among East German males increased between 1989 and 1991, and the homicide rate remains high when compared with West German males (although lower than that of American males). Homicide among German females is less common, presently about equally likely in East and West. Violent crime in general has become more frequent in Germany, and citizen fear of crime has increased markedly, especially in the East. Non-citizens are convicted for an increasing number of homicides and assaults. Rates of suicide were declining in East and West before reunification, and these rates have continued to decline. Social changes in Europe since 1989 have led to noticeable increases in violence and homicide in Germany, which in turn have reduced feelings of security among German citizens, especially in the East. Suicide rates have not been affected.     

Is the link between alcohol and cardiovascular death among young Russian men attributable to misclassification of acute alcohol intoxication? Evidence from the city of Izhevsk

BACKGROUND: Research on the aetiology of sudden cardiac death among young men in Russia strongly suggests an association with binge drinking. However, the possibility remains that such deaths are misclassified as being attributable to cardiovascular disease when they are really caused by acute alcohol poisoning. OBJECTIVE: To describe postmortem levels of blood alcohol in Russian men dying from various causes and so determine whether deaths from alcohol poisoning are being misclassified as cardiovascular deaths. SETTING: Ishevsk, capital of the Udmurt Republic, situated in the Ural region of the Russian Federation. METHODS: The study was part of a larger one on adult mortality. The study sample was 309 deaths among men aged 20-55 dying between August 1998 and March 1999 from other than neoplasms, infectious diseases or unspecified causes and on whom necropsy records could be obtained. Information on cause of death was extracted from death certificates and data on postmortem blood alcohol concentration (BAC) from forensic records. Blood alcohol concentrations were adjusted where necessary to allow for delay in necropsy. RESULTS: Medium or greater levels of intoxication occurred in a quarter of those recorded as dying from cardiovascular disease but in over half of those dying from external causes. BAC levels consistent with at least strong intoxication were seen in 13.5% of deaths from cardiovascular disease and 27.1% from external causes. No cardiovascular deaths had BAC at levels usually thought to be fatal while this level was seen in 26% of deaths from accidental poisoning. CONCLUSION: Evidence of recent consumption of alcohol is common among Russian men dying under the age of 55, with severe intoxication common where death is from external causes. However, the high death rates from cardiovascular disease in Russia cannot be explained by misclassification of deaths attributable to acute alcohol poisoning. This study thus resolves one of the outstanding controversies in the story of alcohol and cardiovascular disease in the former Soviet Union.     

School-associated student homicides--United States, 1992-2006

School-associated student homicide events, especially those involving multiple victims, generate considerable media attention, prompting questions regarding whether rates of school-associated violent deaths are increasing and regarding the characteristics of such events. During the 1990s, the rate of school-associated single-victim student homicides decreased significantly, whereas rates for school-associated homicides in which two or more students were killed (i.e., multiple-victim homicides) increased. Additional studies of such events during the same decade documented the rarity of lethal school-associated violence. To 1) update temporal trends in rates for school-associated student homicides during July 1992-June 2006 and 2) describe the epidemiologic characteristics of school-associated student homicides that occurred during July 1999-June 2006 (the period for which the most recent data are available), CDC analyzed data from the School-Associated Violent Death (SAVD) study. This report describes the results of that analysis, which indicated that rates of school-associated student homicides decreased during the overall period, July 1992-June 2006, but stabilized during July 1999-June 2006, when 116 students were killed in 109 school-associated homicide events. Although school-associated student homicides are rare and represent approximately 1% of homicides that occur among school-age youths, schools should expand use of comprehensive measures to prevent behaviors that often precede fatal violence. In addition, comprehensive approaches that address risk factors and protective risk factors for violence at the individual, family, school, and community levels will help address violence both on and off school grounds.     

Retrospective study of concentration levels of Pb, Cd, Cu and Se in serum of the Czech population in time period 1970-1999.

The retrospective study evolution of trends in concentrations of Cd, Pb, Cu and Se in the population of the Czech Republic over 30 years period could be useful in design of regulations concerning health protection, prevention of diseases caused by deficiency of trace elements and have considerable economic importance. Concentrations of the named elements in the serum were determined by means of atomic absorption spectrometry (AAS) after mineralisation in a microwave digestion system. The 1433 samples of serum (730 males and 703 females, average age 48.7 and 49.1 years respectively) from a time period 1970-1995 were obtained from the Serum bank of National Institute of Public Health and volunteers (1999). Serum samples from the years 1970, 1975, 1980, 1985, 1990, 1995 and 1999 were examined. The accuracy of the results was checked by means of the Control material Seronorm Whole Blood 404,107 and Seronorm Serum 704,121, Nycomed. The concentration of Cd had a decreasing trend for the years 1975-1999 (0.82 microgram Cd.l-1 vs 0.47 microgram Cd.l-1). The levels of Pb are falling in the interval 1970-1980 (15.6 micrograms Pb.l-1 vs. 6.6 micrograms Pb.l-1). In year 1985 concentration of Pb increased (10.7 micrograms Pb.l-1) but subsequently decreased again (1995--6.4 micrograms Pb.l-1). In year 1999, it was 8.9 micrograms.l-1. The concentration of Cu decreased in period 1970-1990 (1525 micrograms Cu.l-1 vs. 990 micrograms Cu.l-1). From 1990 to 1999 the levels of Cu had an increasing tendency (1999--1060 micrograms Cu.l-1). Levels of Se in the interval 1970-1985 were surprisingly equal (58.1 micrograms Se.l(-1)-54.4 micrograms Se.l-1). However in the interval 1986-1990 the level of Se sharp declined (38.3 micrograms Se.l-1). Since 1990 levels of Se in serum increased again, up to 67.1 micrograms Se.l-1 in 1999. Statistically significant differences between men and women were found only in Cu and Pb concentrations. Concentrations of under study elements corresponded to the published values concerning unexposed population.     

A profile of homicides on the streets and in the homes of New York City.

Although prior research has found that homes containing firearms and illicit drug and ethanol users are more likely to be the scene of a homicide than homes that do not contain these elements, the authors studied homicides on the streets as well as in homes so as to assess the role of firearms, cocaine, and ethanol in both settings. Using the files of the Chief Medical Examiner, the authors reviewed all 4,468 homicides occurring in New York City in 1990 and 1991. The most frequent places of occurrence were the streets and other outdoor places (49.6 percent) and the victims'' homes (19.3 percent). Firearms were the cause of death for 49.6 percent of homicides in the home and 80.3 percent of those on the streets. Use of cocaine and ethanol was found more frequently among victims killed on the streets than those killed at home. In addition, victims killed on the streets were more likely to be male, ages 15-24 years, and African American. Further research in regard to prevention and intervention strategies is needed, keeping in mind the different patterns of homicide on the streets compared with those occurring in other settings.     

Fatal violence among spouses in the United States, 1976-85.

In this paper we examine patterns and trends in homicides between marriage partners in the United States for 1976 through 1985 using data from the Federal Bureau of Investigation's Supplemental Homicide Reports (FBI-SHR). We identified 16,595 spouse homicides accounting for 8.8 per cent of all homicides reported to the FBI-SHR during this 10-year period. The rate of spouse homicide for this 10-year period was 1.6 per 100,000 married persons. The risk of being killed by one's spouse was 1.3 times greater for wives than for husbands. Black husbands were at greater risk of spouse homicide victimization than Black wives or White spouses of either sex. The risk of victimization was greater for spouses in interracial than in intraracial marriages and increased as age differences between spouses increased. From 1976 through 1985, the risk of spouse homicide declined by more than 45.0 per cent for both Black husbands and wives but remained relatively stable for White husbands and wives. Demographic patterns in the risk of spouse homicide were similar to those reported for nonfatal spouse abuse suggesting that the causes of spouse homicide and nonfatal spouse abuse may be similar.     

Homicide mortality in the United States, 1935-1994: age, period, and cohort effects

The authors analyzed homicide mortality data for the United States from 1935 to 1994, to delineate temporal trends and birth cohort patterns. This study included 850,822 homicide-attributed deaths documented by the National Center for Health Statistics, and incorporated graphical presentation, median polish, and Poisson regression modeling in an age-period-cohort analysis. Death rates from homicide in the United States doubled in the past four decades, with most of the increase having occurred during the 1960s and early 1970s. Poisson regression models confirmed that the rise of homicide mortality in both men and women was largely attributable to a significant period effect between 1960 and 1974. No discernible cohort patterns were found among women. However, homicide rates for recent male birth cohorts appeared to peak at younger ages and at higher levels. A significant increase in homicide mortality risk beginning with males born around 1965 was found by examining the residuals of median polish, and the second-order changes in the regression coefficients from the age-period-cohort model. The hike of homicide mortality during 1985 and 1994 was explained by this cohort effect. Increased prevalence of substance abuse and availability of firearms are two likely factors underlying this disturbing cohort pattern.     

Increases in age-group-specific injury mortality--United States, 1999-2004

From 1979 to 1999, total injury mortality rates declined overall in the United States, despite increases in suicide rates in the late 1980s and in homicide rates in the early 1990s (CDC, unpublished data, 2007). From 1999 to 2004, however, total injury mortality rates increased 5.5%, from 53.3 to 56.2 per 100,000 population, the first sustained increase in 25 years. To assess this increase, CDC analyzed the most recent data from the National Vital Statistics System (NVSS). This report summarizes the results of that analysis, which determined that U.S. mortality rates increased from 1999 to 2004 for unintentional injuries, suicides, and injuries of undetermined intent; homicide rates were stable. Among persons aged 45-54 years, the total injury mortality rate increased 24.5%, including an 87.0% increase in the mortality rate from unintentional poisoning (most commonly drug poisoning) and a 48.0% increase in suicide by hanging/suffocation. Among persons aged 20-29 years, the total injury mortality rate increased 7.7%, including a 92.5% increase in the death rate from unintentional poisoning and a 31.7% increase in suicide by hanging/suffocation. Parallel increases in multiple categories and mechanisms of injuries within these two age groups suggest an increase in one or more shared risk factors (e.g., drug abuse); prevention programs that focus on shared risk factors might help reduce deaths from injuries.     

Post-neonatal mortality in Norway 1969-95: a cause-specific analysis

BACKGROUND: We recently reported increased social inequality for post-neonatal death. The aim of the present study was to investigate the association between socioeconomic status and cause-specific post-neonatal death. METHODS: All 1,483,857 live births recorded in the Medical Birth Registry of Norway from 1969-95 with information on parents' education were included. During the post-neonatal period (from 28 to 364 days of life) 4,464 infants died. Differences between education groups were estimated as risk differences, relative risks, population attributable fractions, and relative index of inequality. RESULTS: The major causes of death were congenital conditions, sudden infant death syndrome (SIDS), and infections. Post-neonatal mortality declined from 3.2/1,000 in the 1970s to 1.9/1,000 in the 1990s, mainly due to reduced mortality from congenital conditions. The absolute risk for SIDS increased by 0.51/1,000 in the same period among infants whose mothers had low education, while it decreased by 0.56/1,000 for those whose mothers had high education. The relative risk for SIDS among infants whose mothers had low education increased from 1.02 in the 1970s to 2.39 in the 1980s and 5.63 in the 1990s. Among infants whose fathers were not recorded in the Birth Registry, the absolute risk of SIDS increased by 0.79/1,000 from the 1970s to the 1990s. CONCLUSIONS: Increased social inequality for post-neonatal death was primarily due to increases in the absolute and relative risks of SIDS among infants whose mothers have low education. Social inequality widened during the study period for SIDS and deaths caused by infections.     

The evolving pattern of avoidable mortality in Russia

BACKGROUND: Life expectancy at birth in Russia is over 12 years less than in western Europe. This study explores the possible role of medical care in explaining this gap by examining the evolving pattern of mortality amenable to timely and effective medical care in Russia compared with Estonia, Latvia, and Lithuania, and the UK. METHODS: Analysis of standardized death rates from causes amenable to health care (treatable) or inter-sectoral health policies (preventable) in all regions and decomposition of differences in life expectancy between Russia and the UK by age, sex, and cause of death for the period 1965-1999/2000. RESULTS: Death rates from treatable causes remained stable between the mid-1960s and mid-1980s in Russia and the Baltic republics while steadily falling in the UK to less than half the rate in Russia. In the 1990s, rates increased in the former Soviet republics, reaching a peak in 1994 but reversing again in Russia in 1998. Deaths from causes amenable to inter-sectoral health interventions were higher in the UK in 1965 than in the Soviet Union but subsequently fell steadily while they increased in the East. Between 1965 and 1999, the male life expectancy gap between Russia and the UK rose from 3.6 to 15.1 years (women: 1.6 and 7.4 years). Treatable causes became an increasingly important contributor to this gap, accounting for almost 3 years by the end of the 1990s in men and 2 years in women. In Russia, elimination of treatable causes of death would have increased life expectancy by 2.9 years in men in 1995/99 compared with 1.2 years in the UK (women: 3.3 and 1.8 years), suggesting that, were the outcomes of health care achieved in the UK to be obtained in Russia, life expectancy for men might improve by about 1.7 years and for women by about 1.5 years. CONCLUSIONS: Our findings suggest that the Soviet health care system has failed to match the achievements of the West over the past three decades, highlighting the need to establish a system that provides effective and equitable care for the Russian population.     

Alcohol use and interpersonal violence: alcohol detected in homicide victims.

To characterize the relationship between alcohol use and homicide victimization, we used data from the Los Angeles City Police Department and the Los Angeles Medical Examiner's Office to study 4,950 victims of criminal homicides in Los Angeles in the period 1970-79. Alcohol was detected in the blood of 1,883 (46 per cent) of the 4,092 victims who were tested. In 30 per cent of those tested, the blood alcohol level was greater than or equal to 100 mg/100 ml, the level of legal intoxication in most states. Blood alcohol was present most commonly in victims who were male, young, and Latino, categories where rates have been increasing at an alarming pace. Alcohol was also detected most commonly in victims killed during weekends, when homicides occurred in bars or restaurants, when homicides resulted from physical fights or verbal arguments, when victims were friends or acquaintances of offenders, and when homicides resulted from stabbings. The evidence for alcohol use by homicide victims focuses attention on the need for controlled epidemiologic studies of the role played by alcohol as a risk factor in homicide and on the importance of considering situational variables in developing approaches to homicide prevention.     

Salmonella enteritidis infections, United States, 1985-1999

Salmonella enterica serotype Enteritidis emerged as an important illness during the 1980s. Investigations showed that consumption of undercooked eggs was the major risk factor for disease, and a variety of prevention and control efforts were initiated during the 1990s. We describe sporadic infections and outbreaks of S. Enteritidis in the United States from 1985 through 1999 and discuss prevention and control efforts. After reaching a high of 3.9 per 100,000 population in 1995, S. Enteritidis infections declined to 1.98 per 100,000 in 1999. While the total number of outbreaks decreased by half, those in the western states tripled. Outbreaks of S. Enteritidis phage type 4 infections accounted for 49% of outbreaks in 1999. Outbreak-associated deaths in health facilities decreased from 14 in 1987 to 0 in 1999. Overall, rates of sporadic S. Enteritidis infection, outbreaks, and deaths have declined dramatically. For further reductions, control measures should continue to be applied along the entire farm-to-table continuum.     

Juvenile delinquency in Bendel state, Nigeria

A study of the juvenile delinquency in Bendel State of Nigeria, over a period of 12 years,has revealed an upsurge in its prevalence. More males were convicted than females, and more females under the age of 14 years were convicted than those in the 14- to 18-year-old age group. Most of the convictions resulted from crimes against property. Many juveniles in remand homes came from broken homes. Some ways of solving the problem are discussed.     

核工业职工全因死亡的动态分析

应用ＩＣＤ－９死因分类原则和流行病学调查方法，在核工业１１个代表性单位进行了全因死亡调查。结果表明：死亡有逐年增高趋势，并随年龄增长而增加；而平均死亡年龄，工龄均有逐年增高趋势。肿瘤死亡表现为逐年增高，其中肺癌死亡在７０年代中期开始增加，１９８５－１９９０年增加明显；肝癌，胃癌１９７５年呈增加趋势，但差异无显著性。     

Regional variations in homicide mortality in Jalisco,Mexico

The present study describes regional variations in homicide rates in Jalisco State, Mexico, in 1989-1991, 1994-1996, and 1999-2000, analyzing the trends by gender and socioeconomic stratum. Using mortality data generated by the National Institute for Statistics, Geography, and Information Technology, homicide rates adjusted by age and gender were calculated, along with rate/female rate ratios; rate ratios by socioeconomic stratum and 95% confidence intervals were also calculated. According to the results, the homicide rate showed: a downward trend in the 1990s; a regional homicide mortality pattern, with the highest rates in peripheral regions, considered among the poorest areas in the State; municipalities with the lowest socioeconomic conditions also presenting a statistically significant excess homicide mortality; and an evident over-mortality from homicide among males. The results point to tasks and challenges for public health and law enforcement institutions, including the need to implement different inter-institutional policies that take into consideration the characteristics of homicide and violent crime in Jalisco.

High cardiovascular mortality in Russia cannot be explained by the classical risk factors. The Arkhangelsk study 2000

Since the beginning of the 1990s the public health situation in Russia has been characterized by an extremely high mortality and a significant reduction in life expectancy. Cardiovascular diseases remained the major cause of death. Only a few large population studies were conducted in Russia during this period. A total of 1968 men and 1737 women aged 18–75 years participated in a health survey in Arkhangelsk, Russia, over the period 1999–2000. Investigation included assessment of classic cardiovascular risk factors (family history, smoking, blood pressure, and blood lipids) along with general health variables. The paper presents sex specific data on risk factors for coronary heart disease. Though the cardiovascular mortality is high in Russia, the calculated risk for coronary heart disease (the Framingham risk score and the Norwegian risk score) was lower in all age groups of men and women in Arkhangelsk compared with studies from the Western Europe and USA. Our data suggest that high cardiovascular mortality in Russia may be driven not only by the classic risk factors for coronary heart disease.
