Among the 87 deaths in the United States in 1969 for which a causal relationship to pesticides could not be excluded, there were 62 valid accidents, 20 intentionally inflicted deaths, and five deaths incorrectly attributed to pesticides. The reduction in the number of such deaths compared to the decade and a half prior to 1962 probably involves a trend. As in the past, a disproportionate fraction of the victims were children, boys and men, and nonwhites. Findings in four cases (three in 1969) were consistent with the conclusion that intensive inhalation of an aerosol can sensitize the heart to fatal arrhythmia, even though there is no intentional misuse of the aerosol and no attempt to seek a thrill. Medical examiners should be alert to the possibility of such deaths associated with both pesticide and non-pesticide aerosols. 相似文献

The associations between temperature and daily mortality was studied among the citizens of Oslo, Norway, 1990–1995. Data on daily mortality were linked with daily temperatures, relative humidity, wind velocity and air pollution. At temperatures below 10 °C, a 1 °C fall in the last 7 days average temperature increased the daily mortality from all diseases by 1.4%, respiratory diseases 2.1%, and cardiovascular diseases 1.7%. Above 10 °C, there was no statistically significant increase in daily mortality, except for respiratory mortality, which increased by 4.7% per 1 °C increase in the last 7 days average temperature. Daily mortality in Oslo increases with temperatures falling below 10 °C. The increase starts at lower temperatures than shown in warmer regions of the world, but at higher temperatures than in regions with even colder climates. As well insulated and heated dwellings are standard in Norway today, more adequate clothing during outdoor visits is probably the most important preventive measure for temperature related mortality. 相似文献

Using United States vital statistical data we examined trends in infant deaths from Respiratory Distress Syndrome/Hyaline Membrane Disease (RDS/HMD) for 1969 to 1983, by race and age at death. In order to improve comparability of diagnosis across two revisions of the International Classification of Diseases, deaths from RDS/HMD were ascertained using both underlying and associated causes of death. These data document a 2 per cent per year increase in infant mortality attributed to RDS/HMD for all races during interval I (1969-73) followed by 9 per cent per year decreases during intervals II (1974-78) and III (1979-83). However, there was a marked difference between Whites and Blacks in these trends. In the White population, RDS/HMD infant mortality increased by 2.2 per cent per year in interval I but then decreased by 10.5 per cent per year in interval II and 8.9 per cent per year in interval III. Among Blacks, on the other hand, the initial increase in RDS/HMD mortality was steeper (5.2 per cent per year) and the subsequent decreases were less (6.3 per cent per year and 8.0 per cent per year). As a result, the Black-White ratio in infant mortality attributed to RDS/HMD increased from 1.32 in 1969-73, to 1.59 in 1974-78 and to 1.72 in 1979-83. The proportion of RDS/HMD deaths that occurred in the postneonatal period increased from 1.1 per cent in interval I to 3.6 per cent in interval II to 5.0 per cent in interval III.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

STUDY OBJECTIVE--The aim was to examine whether a high intake of aluminium containing antacids is a risk for Alzheimer's disease. DESIGN--The mortality from dementia (1970-87), coded from death certificates as underlying or contributory cause of death, was compared with national rates in a cohort of patients who had surgery for gastroduodenal ulcer disease between 1911 and 1978. SETTING--Patient data were obtained from patient records from major hospitals in western Norway. PARTICIPANTS--4179 patients were identified who met the study criteria, which included having had a documented stomach operation, having a reliably identifiable personal number, and being alive on Jan 1, 1970. MEASUREMENTS AND MAIN RESULTS--The standardised mortality ratio for dementia was 1.10 (95% CI 0.85-1.40, n = 64) for all patients, while for patients operated on in the period 1967-78 it was 1.25 (95% CI 0.66-2.13, n = 13). CONCLUSIONS--As the majority of patients operated on after 1963 have probably been heavy consumers of aluminium containing antacids, the study provides meager evidence that a high intake of aluminium is an important risk factor for Alzheimer's disease, the major cause of dementia. However, the possibility of a raised mortality from Alzheimer's disease cannot be ruled out due to probable misclassification both in diagnosis and exposure. In addition, the observation period may have been too short to detect an effect since the latent period for Alzheimer's disease may be very long. 相似文献

AIMS: The pattern of mortality among many groups of indigenous people has been shown to be disadvantageous in comparison with the general population. Knowledge regarding causes of death among the Sami population in the northern part of Norway is limited. The Sami constitute an ethnic minority whose lifestyle diverges from that of the rest of the population. METHODS: A cohort of 19,801 persons of Sami origin was followed up to evaluate specific causes of mortality during the period 1970-98. Standardized mortality rates (SMR) were calculated using the rural population of the three Norwegian counties included in the study as a reference population. RESULTS: Among Sami, 5,955 total deaths were observed, as opposed to 5,537 expected (SMR = 1.08). For both Sami women and men a significantly higher SMR for cerebrovascular diseases was found, which was more pronounced for women. For Sami men, an excess SMR for violent death was observed (SMR 1.32, 95% confidence interval (CI) 1.20-1.46); this was highest among Sami men living in a reindeer-breeding family. For both genders, mortality from all malignant neoplasms combined was lower than in the reference population. SMRs were 0.86 (95% CI 0.79-0.94) and 0.89 (95% CI 0.80-0.99) for men and women, respectively. Low SMRs were also observed for chronic liver diseases, 0.18 (95% CI 0.02-0.63) and 0.12 (95% CI 0.00-0.68) for Sami men and women, respectively. To be a member of a reindeer breeding household appeared to offer protection from mortality caused by circulatory system diseases in men, especially mortality from ischaemic heart disease. CONCLUSIONS: The total mortality in the North Norway Sami population, an ethnic minority in Norway, was slightly higher when compared with a regional reference population. The differences observed when evaluating mortality by diagnosis might be due to lifestyle, diet, psychosocial, and/or genetic factors. 相似文献

Of all weather-related disasters that occur in the United States, floods are the main cause of death, and most flood-related deaths are attributed to flash floods. Whenever a weather-related disaster involves 30 or more deaths or more than $100 million in property damage, the National Weather Service (NWS) forms a survey team to investigate the disaster and write a report of findings. All NWS survey reports on flash floods issued during 1969-81 were reviewed to determine the mortality resulting from such floods, the effect of warnings on mortality, and the circumstances contributing to death. A total of 1,185 deaths were associated with 32 flash floods, an average of 37 deaths per flash flood. The highest average number of deaths per event was associated with the four flash floods in which dams broke after heavy rains. Although there were 18 flash floods in 1977-81 and only 14 in 1969-76, the number of deaths was 2 1/2 times greater during the earlier period. More than twice as many deaths were associated with flash floods for which the survey team considered the warnings inadequate than with those with warnings considered adequate. Ninety-three percent of the deaths were due to drowning and 42 percent of these drownings were car related. The other drownings occurred in homes, at campsites, or when persons were crossing bridges and streams. The need for monitoring dams during periods of heavy rainfall is highlighted. 相似文献

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. 相似文献

The authors collected and analyzed cancer incidence data for Alaska Natives (Indians, Eskimos, and Aleuts) for the 15-year period 1969-83 by ethnic and linguistic groups. Compared with U.S. whites, observed-to-expected ratios are high in more than one ethnic group for cancer of the nasopharynx, salivary gland, liver, gallbladder, and cervix. Low ratios were found for cancer of the breast, uterus, bladder, and melanoma. In Alaska, Eskimos have the highest risk for cancer of the esophagus and liver and the lowest risk for breast and prostate cancer. Risk for multiple myeloma in Indian men in Alaska exceeds not only those of other Native groups in Alaska but that in U.S. whites as well. Despite the short period studied, increases in cancer incidence over time can be documented for lung cancer in Eskimo men and women combined, and for cervical cancer, especially in Indian women. 相似文献

Five-year follow-up of a community-based, 77+ old cohort including incident dementia cases was used to evaluate the impact of dementia on the risk of death, taking into account other chronic conditions potentially related to death, and contrasting Alzheimer's disease (AD), and vascular dementia (VaD). In this population, 70% of the dementia cases died during the five years after diagnosis, with a mortality rate specific for dementia of 2.4 per 100 person-years. After controlling for sociodemographic variables and comorbidity, 14% of all deaths could be attributed to dementia with a risk of death among demented subjects twice as high as that for non-demented people. Mortality risk ratios were 2.0 (95% confidence interval 1.5-2.7) for AD and 3.3 (95% confidence interval 2.0-5.3) for VaD. This study confirms that dementing disorders are a major risk factor for death. Even in the oldest old (85+), dementia shortens life, especially among women. 相似文献

The objective of this study was to evaluate mortality rates from ischemic heart disease among Icelanders during the period of 1951 to 1985. In some developed countries, the number of deaths from ischemic heart disease declined markedly in this time period, and it is interesting to study whether the same has occurred in Iceland. The study was based on information obtained from the Statistical Bureau of Iceland, which keeps records of deaths based on death certificates as well as other population records. Nonparametric tests were used to correlate death rates and calendar years. Rates per 100,000 were calculated and plotted. The results indicated that the mortality rates from ischemic heart disease among Icelanders have not yet peaked. 相似文献

This paper presents an analysis of state trends in infant mortality rates (IMRs) for 1968-83. In order to take into account the large random error component associated with state IMRs, weighted least squares estimates are used to fit log-linear models to these trends. Using simulated data, these estimates are shown to be nearly unbiased and to provide valid significance tests. However, the power to detect changes in trend is rather limited, especially in small states. Using these methods, separate analyses of White IMRs in 49 states and non-White IMRs in 30 states were completed. Nine states are identified which had infant mortality trends less favorable than the national experience and 1981-83 rates more than 5 per cent above the national average. 相似文献

Poliomyelitis continued to be a rare disease in England and Wales in the period 1969-75. Only 31 paralytic and 44 cases of possible non-paralytic poliomyelitis were recorded during the 7 years. Of the 31 paralytic cases approximately one third were vaccine-associated; 3 were patients who had recently received oral poliovaccine and 7 had been in contact with a vaccinated person. Five of these 7 patients were parents of recently vaccinated children. The rate of vaccine-associated poliomyelitis was estimated in recipients to be 0.2 and in contacts 0.4 per million doses of vaccine given. Marker test results were reported on 555 strains of poliomyelitis virus isolated during 1969-75, using the reproductive capacity temperature test. Forty-eight (8.6%) resembled wild virus in this property, 15 strains being type 1, 8 type 2 and 25 type 3. Most of these isolations of apparently wild virus were from excreters with no symptoms of poliomyelitis, although 3 of the 15 type 1 strains were from patients with paralytic poliomyelitis and 3 from possible cases of non-paralytic poliomyelitis. None of the 8 apparently wild type 2 viruses was from a case of paralytic illness and only 1 of the 39 type 3 strains. Eleven of the 31 paralytic cases were in patients in whom the infection was likely to have been acquired abroad. 相似文献

BackgroundAlzheimer's and related diseases have become a major public health issue in all developed countries, particularly with the aging of the population. Given the potential burden of these pathologies, the French government launched a third National Alzheimer's Strategic Plan 2008–2012 in 2008. The aim of the study was to provide French data on the mortality statistics of Alzheimer's and related diseases by age, gender, and geographical area.MethodsAnalyses were based on the number of deaths from Alzheimer's disease (AD) and dementia, extracted from the 2000–2006 French National Mortality Registry (Inserm-Centre d’épidémiologie sur les causes médicales de décès [CépiDc]). Underlying and multiple causes of death were taken into account. Gender, age, area of residence, and place of death were noted for all subjects deceased with AD or dementia. Mortality rates were standardized on the truncated 60+ French 2006 population. Mortality rates were also estimated by 5-year age groups. Causes of death in demented and nondemented people were compared by estimating an age-adjusted relative-risk ratio.ResultsIn France, in 2006, AD or dementia was reported as the underlying cause or a multiple cause of death on 45,597 death certificates. Among these death certificates, 70% were women and the mean age at death was 85.9 years. Age-standardized mortality rates were 341/100,000 person-years for men and 333/100,000 person-years for women. Age-specific mortality rates increased with age and were higher in women than in men over 90 years of age. The analysis of the changes in mortality rates showed an overall increase of 11.3% between 2000 and 2006. The most frequent underlying cause when AD or dementia was mentioned as an associated cause were cardiovascular diseases (40.5%), neoplasms (11.9%), and endocrine diseases (8.5%).ConclusionThe analysis of mortality data on AD and dementia provides insight into the burden of these diseases in France. If carried out regularly, these analyses can provide trend analyses of mortality rates. 相似文献

Between 1969 and 1990 strains of Staphylococcus aureus from 359 outbreaks and sporadic cases of staphylococcal food poisoning in the United Kingdom were examined in the PHLS Food Hygiene Laboratory for the production of enterotoxin. In a number of instances the incriminated foods were also examined for the presence of enterotoxin. Strains from 79% of incidents produced enterotoxin A alone or together with another enterotoxin. The level of S. aureus present in the foods ranged from no viable S. aureus detected to 1.5 x 10(10) c.f.u./g with a median of 3.0 x 10(7) c.f.u./g. Enterotoxin was detected in foods in the absence of viable S. aureus in only two outbreaks and in both cheese was the implicated food. Meat, poultry or their products were the vehicle in 75% of incidents with ham and chicken most frequently implicated. Other foods included fish and shellfish (7%) and milk and milk products (8%). Most contamination took place in the home followed by restaurants and shops. Seventy-one percent of the incident strains were lysed by phages of group III or I/III. 相似文献

Very little information is available concerning the frequency of influenza in East Africa. Following recent outbreaks of influenza in Uganda, that were due to the A2/Hong Kong/68 virus, it was considered useful to obtain information relating to the prevalence of infection due to this virus and to the current strain of influenza B virus, not only in Uganda but also in the neighbouring territories of Kenya and Tanzania. The results of serological testing of sera showed that widespread outbreaks of influenza A2/Hong Kong/68 infection had occurred recently in all three territories, while there was evidence of sporadic infection in all territories by the current influenza B strain. Despite the favourable climate of East Africa, it is evident that widespread outbreaks of influenza can occur, and these may arise during the period of the year when influenza is rare in countries with temperate climates. Influenza can easily spread to other countries via air travellers to and from East Africa. 相似文献
