Water traffic accidents, drowning and alcohol in Finland, 1969-1995. (1/11460)

OBJECTIVE: To examine age- and sex-specific mortality rates and trends in water traffic accidents (WTA), and their association with alcohol, in Finland. MATERIALS AND METHODS: National mortality and population data from Finland, 1969-1995, are used to analyse rates and trends. The mortality rates are calculated on the basis of population, per 100000 inhabitants in each age group (<1, 1-4, 5-14, 15-24, 25-44, 45-64, > or = 65), and analysed by sex and age. The Poisson regression model and chi2 test for trend (EGRET and StatXact softwares) are used to analyse time trends. RESULTS: From 1969 through 1995 there were 3473 (2.7/100000/year; M:F= 20.4:1) WTA-related deaths among Finns of all ages. In 94.7% of the cases the cause of death was drowning. Alcohol intoxication was a contributing cause of death in 63.0% of the fatalities. During the study period the overall WTA mortality rates declined significantly (-4% per year; P < 0.001). This decline was observed in all age groups except > or = 65 year olds. The overall mortality rates in WTA associated with alcohol intoxication (1987-1995) also declined significantly (-6%; P = 0.01). CONCLUSIONS: In Finland, mortality rates in WTA are exceptionally high. Despite a marked decline in most age groups, the high mortality in WTA nevertheless remains a preventable cause of death. Preventive countermeasures targeted specifically to adult males, to the reduction of alcohol consumption in aquatic settings and to the use of personal safety devices should receive priority.  (+info)

A method for calculating age-weighted death proportions for comparison purposes. (2/11460)

OBJECTIVE: To introduce a method for calculating age-weighted death proportions (wDP) for comparison purposes. MATERIALS AND METHODS: A methodological study using secondary data from the municipality of Sao Paulo, Brazil (1980-1994) was carried out. First, deaths are weighted in terms of years of potential life lost before the age of 100 years. Then, in order to eliminate distortion of comparisons among proportions of years of potential life lost before the age of 100 years (pYPLL-100), the denominator is set to that of a standard age distribution of deaths for all causes. Conventional death proportions (DP), pYPLL-100, and wDP were calculated. RESULTS: Populations in which deaths from a particular cause occur at older ages exhibit lower wDP than those in which deaths occur at younger ages. The sum of all cause-specific wDP equals one only when the test population has exactly the same age distribution of deaths for all causes as that of the standard population. CONCLUSION: Age-weighted death proportions improve the information given by conventional DP, and are strongly recommended for comparison purposes.  (+info)

The meaning and use of the cumulative rate of potential life lost. (3/11460)

BACKGROUND: The 'years of potential life lost' (YPLL) is a public health measure in widespread use. However, the index does not apply to the comparisons between different populations or across different time periods. It also has the limit of being cross-sectional in nature, quantifying current burden but not future impact on society. METHODS: A new years-lost index is proposed-the 'cumulative rate of potential life lost' (CRPLL). It is a simple combination of the 'cumulative rate' (CR) and the YPLL. Vital statistics in Taiwan are used for demonstration and comparison of the new index with existing health-status measures. RESULTS: The CRPLL serves the purpose of between-group comparison. It can also be considered a projection of future impact, under the assumption that the age-specific mortality rates in the current year prevail. For a rare cause of death, it can be interpreted as the expected years (days) of potential life lost during a subject's lifetime. CONCLUSIONS: The CRPLL has several desirable properties, rendering it a promising alternative for quantifying health status.  (+info)

Risk factors for injuries and other health problems sustained in a marathon. (4/11460)

OBJECTIVES: To identify risk factors for injuries and other health problems occurring during or immediately after participation in a marathon. METHODS: A prospective cohort study was undertaken of participants in the 1993 Auckland Citibank marathon. Demographic data, information on running experience, training and injuries, and information on other lifestyle factors were obtained from participants before the race using an interviewer-administered questionnaire. Information on injuries and other health problems sustained during or immediately after the marathon were obtained by a self administered questionnaire. Logistic regression analyses were undertaken to identify significant risk factors for health problems. RESULTS: This study, one of only a few controlled epidemiological studies that have been undertaken of running injuries, has identified a number of risk factors for injuries and other health problems sustained in a marathon. Men were at increased risk of hamstring and calf problems, whereas women were at increased risk of hip problems. Participation in a marathon for the first time, participation in other sports, illness in the two weeks before the marathon, current use of medication, and drinking alcohol once a month or more, were associated with increased self reported risks of problems. While increased training seemed to increase the risk of front thigh and hamstring problems, it may decrease the risk of knee problems. There are significant but complex relations between age and risk of injury or health problem. CONCLUSIONS: This study has identified certain high risk subjects and risk factors for injuries and other health problems sustained in a marathon. In particular, subjects who have recently been unwell or are taking medication should weigh up carefully the pros and cons of participating.  (+info)

Disabling injuries of the cervical spine in Argentine rugby over the last 20 years. (5/11460)

OBJECTIVE: To investigate the incidence and risk factors of disabling injuries to the cervical spine in rugby in Argentina. METHODS: A retrospective review of all cases reported to the Medical Committee of the Argentine Rugby Union (UAR) and Rugby Amistad Foundation was carried out including a follow up by phone. Cumulative binomial distribution, chi 2 test, Fisher test, and comparison of proportions were used to analyse relative incidence and risk of injury by position and by phase of play (Epi Info 6, Version 6.04a). RESULTS: Eighteen cases of disabling injury to the cervical spine were recorded from 1977 to 1997 (0.9 cases per year). The forwards (14 cases) were more prone to disabling injury of the cervical spine than the backs (four cases) (p = 0.03). Hookers (9/18) were at highest risk of injury (p < 0.01). The most frequent cervical injuries occurred at the 4th, 5th, and 6th vertebrae. Seventeen of the injuries occurred during match play. Set scrums were responsible for most of the injuries (11/18) but this was not statistically significant (p = 0.44). The mean age of the injured players was 22. Tetraplegia was initially found in all cases. Physical rehabilitation has been limited to the proximal muscles of the upper limbs, except for two cases of complete recovery. One death, on the seventh day after injury, was reported. CONCLUSIONS: The forwards suffered a higher number of injuries than the backs and this difference was statistically significant. The chance of injury for hookers was statistically higher than for the rest of the players and it was particularly linked to scrummaging. However, the number of injuries incurred in scrums was not statistically different from the number incurred in other phases of play.  (+info)

Mayaro virus disease: an emerging mosquito-borne zoonosis in tropical South America. (6/11460)

This report describes the clinical, laboratory, and epidemiological findings on 27 cases of Mayaro virus (MV) disease, an emerging mosquito-borne viral illness that is endemic in rural areas of tropical South America. MV disease is a nonfatal, dengue-like illness characterized by fever, chills, headache, eye pain, generalized myalgia, arthralgia, diarrhea, vomiting, and rash of 3-5 days' duration. Severe joint pain is a prominent feature of this illness; the arthralgia sometimes persists for months and can be quite incapacitating. Cases of two visitors from the United States, who developed MV disease during visits to eastern Peru, are reported. MV disease and dengue are difficult to differentiate clinically.  (+info)

Assessment of complement deficiency in patients with meningococcal disease in The Netherlands. (7/11460)

The frequency of complement deficiency in 176 of 7,732 patients with meningococcal disease in the Netherlands from 1959 through 1992 was assessed. Complement deficiency was found in six patients (3%): 3 (7%) of the patients with Neisseria meningitidis serogroup C disease, 1 (2%) of the patients with N. meningitidis serogroup A disease, and 2 (33%) of the patients with infections due to uncommon serogroups and nongroupable strains of N. meningitidis. Of 91 additional patients with meningococcal infections due to uncommon serogroups, 33% also had complement deficiency. Thirty-four of the 36 complement-deficient patients with meningococcal disease who were from 33 families were 5 years of age or older. Twenty-six additional complement-deficient relatives were found. Screening individuals with meningococcal disease due to uncommon serogroups who were 5 years of age or older identified 30 of the 33 complement-deficient families. Only 27% of the complement-deficient relatives had had meningococcal disease. This risk was lower for relatives with properdin deficiency (18%) than for those deficient in the late component of complement (38%). Therefore, pedigree studies are warranted for identifying those complement-deficient persons who require vaccination for meningococcal disease.  (+info)

Prediction of life expectancy in patients with primary pulmonary hypertension. A retrospective nationwide survey from 1980-1990. (8/11460)

Primary pulmonary hypertension (PPH) is a progressive disease of unknown etiology usually followed by death within 5 years after diagnosis. Although heart-lung or lung transplantation is now offered to patients with advanced PPH, adequate criteria assessing an accurate prediction of life expectancy in PPH has been difficult to establish. The aims of this study were to identify the characteristic features associated with a poor prognosis in patients with PPH, and to attempt to establish an individual prognostic index that predicts with great accuracy survival or death of PPH after one year, thereby helping to define criteria for patient selection for transplantation. In 1991, a retrospective nation-wide survey on PPH was conducted in Japan, and the clinical and cardiorespiratory variables of 223 PPH cases (female; 144, male; 79) in the period from 1980-1990 were obtained. The mean pulmonary arterial pressure (PPA) was 57.5+/-17.2 mm Hg (mean+/-SD), and the overall median survival time was 32.5 months since the first diagnostic catheterization. The characteristic features of 61 patients who died within one year of catheterization (Nonsurvivors group) were compared to 141 patients who survived one year or more from the time of catheterization (Survivors group). Among several clinical and cardiorespiratory variables, heart rate, PPA, right atrial pressure (PRA), stroke volume index (SI), pulmonary vascular resistance, and partial pressure of carbon dioxide (PaCO2) were significantly different between the two groups. As the independent factors, PPA, PRA, SI, and PaCO2 were selected for the multiple logistic analysis. Using a 0.7 probability cut-point to separate Nonsurvivors from Survivors, 84.6% of Nonsurvivors and Survivors could be correctly predicted from this logistic regression equation. Predictive equations like the present preliminary one can be used in the future to better assess life expectancy in patients with PPH in whom transplantation will be considered.  (+info)

An updated global compilation of 377 new and previously published ages indicates that granitic pegmatites range in age from Mesoarchean to Neogene and have a semi-periodic age distribution. Undivided granitic pegmatites show twelve age maxima: 2913, 2687, 2501, 1853, 1379, 1174, 988, 525, 483, 391, 319, and 72 Ma. These peaks correspond broadly with various proxy records of supercontinent assembly, including the age distributions of granites, detrital zircon grains, and passive margins. Lithium-cesium-tantalum (LCT) pegmatites have a similar age distribution to the undivided granitic pegmatites, with maxima at 2638, 1800, 962, 529, 485, 371, 309, and 274 Ma. Lithium and Ta resources in LCT pegmatites are concentrated in the Archean and Phanerozoic. While there are some Li resources from the Proterozoic, the dominantly bimodal distribution of resources is particularly evident for Ta. This distribution is similar to that of orogenic gold deposits, and has been interpreted to reflect the ...
While several plots of the aggregate age distribution suggest that firm age is exponentially distributed, we find some departures from the exponential benchmark. At the lower tail, we find that very young establishments are more numerous than expected, but they face high exit hazards. At the upper tail, the oldest firms are older than the exponential would have predicted. Furthermore, the age distribution of disaggregated industries (such as the international airline industry) is less regular and can display multimodality. Although we focused on departures from the exponential, we found that the exponential was a useful reference point and endorse it as an appropriate benchmark for future work on industrial structure. ...

Downloadable! Psychological well-being (WB) includes a person?s overall appraisal of his or her life (Global WB) and affective state (Hedonic WB), and it is considered a key aspect of the health of individuals and groups. Several cross-sectional studies have documented a relation between Global WB and age. Little is known, however, about the age distribution of Hedonic WB. It may yield a different view of aging because it is less influenced by the cognitive reconstruction inherent in Global WB measures and because it includes both positive and negative components of WB. In this study we report on both Global and Hedonic WB assessed in a 2008 telephone survey of 340,847 people in the United States. Consistent with prior studies, Global WB and positive Hedonic WB generally had U-shaped age profiles showing increasedWB after the age of 50 years. However, negative Hedonic WB variables showed distinctly different and stronger patterns: Stress and Anger steeply declined from the early 20s, Worry was elevated

Age-standardized rates may be used to compare different geographic areas or time frames to adjust for any differences in the age structure of the populations that could cause a difference in rates.. It reflects the number of events (e.g., deaths, hospitalizations) that would occur for a given population if that population had the same age distribution as the 1991 Canadian population.. Age-standardized rates have been used to make more valid comparisons than comparing crude rates. Standardization requires adjusting for the effects of varying age structures of different populations and over different periods of time. The importance of age-standardization can be illustrated by using Population X, which has a higher proportion of elderly persons than Population Y. The unadjusted or "crude" mortality rate for Population X would be significantly higher than Population Y solely because it has a higher proportion of elderly persons and the elderly have a much higher death rate than younger people. This ...
Age-Adjusted Death Rate: When comparing rates over time or across different populations, crude rates (the number of deaths per 100,000 persons) can be misleading, because differences in the age distributions of the various populations are not considered. Since death is age-dependent, the comparison of crude rates of death can be especially deceptive.. Age-adjusted rates take into account the diverse age distributions of the populations. Valid comparisons between age-adjusted rates can be made, provided the same standard population and age groups have been used in the calculation of the rates. The direct method of adjustment was used to produce the age-adjusted rates for this report. In this method, the population is first divided into reasonable homogeneous age ranges, and the age-specific rate is calculated for each age range. Then, each age-specific rate is weighted by multiplying it by the proportion of the standard population in the respective age group. The age-adjusted rate is the sum of ...

From 1980 to 2010, the crude incidence of diagnosed diabetes increased 161% from 3.3 to 8.6 per 1,000 population. Similarly, the age-adjusted incidence increased 140% from 3.5 to 8.4 per 1,000 population, suggesting that the majority of the change was not due to the aging of the population. However, from 1980 to 2010, incidence did not increase at a constant rate. Both crude and age-adjusted incidence remained unchanged in the 1980s, and then increased in the 1990s through 2010. From 2008 through 2010, both crude and age-adjusted incidence has shown little change.
I produced a methodology capable of aging the species Rana luteiventris by using a process called skeletochronology. My objective was to find out if the age of the individual could be assessed by counting the number of lines of arrested growth (LAGs) from cross-sections of the third digit of the right hind foot. After this process was refined for this particular species, seventy-four individuals were sampled in order to construct a static age distribution of a population of frogs. Samples were collected from May-August 1998 at a small pond in the Lewis and Clark County, Chessman Marshland, 10 km west of Clancy, Montana. Few individuals were found to be five years of age. The majority of the population was dispersed somewhat evenly between metamorphs, 1, 3, and 4-year-old frogs. As expected, no frogs beyond five years of age were observed. There was a notable lack of 2-year-old frogs. However, I was unable to account for the low number of 2-year-old frogs in the population.
Downloadable! This paper proposes the use of optimal grouping methods for determining the various age groups within a population. The cutoff ages for these groups, such as the age from which an individual is considered to be an older person, are then endogenous variables that depend on the entire population age distribution at any given moment. This method is first applied to the age distribution of the United States and subsequently to a group of 12 industrialized countries. The cutoff ages as well as the main indicators of aging are calculated.

A comparison between mean age theory and conventional residence time distributions over a range of quantified mixing levels was conducted using computational fluid dynamics (CFD). The system was a stirred tubular reactor. The model was validated by comparing computationally derived RTD curves with experimentally obtained RTD curves, with quantified differences less than 3%. Mixing was quantified using the Tanks-in-Series model. Mixing levels were set by varying flow rate and impeller rpm. Mean age distributions at the outlet, where experimental RTDs were measured, were very narrow for all levels of mixing studied. RTDs showed expected characteristics; a wider distribution and long decay for high mixing cases and a narrow distribution centered around the mean time for cases approaching plug flow. Mean age distributions remained substantially narrower than RTDs. RTDs and mean age distributions were measured at several locations along the length of the reactor to determine changes in characteristics of

Data analysis. The average annual incidence of cancer in Gipuzkoa for the period 1998-2002 is presented for all sites together, and also for specific sites, and expressed in rates per 100,000 persons at risk per year. Crude, agespecific and age-standardized incidence rates were calculated by gender, using the direct method and adjusted with European and World population data3. Furthermore, cumulative incidence rates were calculated for each site and gender, from birth to 65 and 75 years of age.. The cancer incidence trend for the period 1986-2002 was studied for all tumours and the most frequent sites. The general trend was quantified by applying the Poisson regression12, after adjusting for age, with separate models for men and women. In this model, a linear trend was assumed for the logarithm of the rates. Goodness of fit was assessed by devianceand its degrees of freedom. The significance level was set at 0.05. In the case of prostate cancer, the Poisson model did not fit correlated as a ...
Detrital zircon age distributions provide robust insights into past sedimentary systems, but these age distributions are often complex and multi-peaked, with sample sizes too small to confidently resolve population distributions. This limited sampling hinders existing quantitative methods for comparing detrital zircon age distributions, which show systematic dependence on the sizes of compared samples. The proliferation of detrital zircon studies motivates the development of more robust quantitative methods. We present the first attempt, to our knowledge, to infer probability model ensembles (PMEs) for samples of detrital zircon ages using a Bayesian method. Our method infers the parent population age distribution from which a sample is drawn, using a Monte Carlo approach to aggregate a representative set of probability models that is consistent with the constraints that the sample data provide. Using the PMEs inferred from sample data, we develop a new estimate of correspondence between ...
The data reported in this table are derived from the HIPE (Hospital In-Patient Enquiry) data set, which records data on discharges from all publicly funded acute hospitals. Age-standardised discharge rates by county, sex and all procedures are presented. These allow comparison of discharge rates between populations of different age composition, and also of discharge rates over time. The age-standardised discharge rate (SDR) for an area is the number of discharges (per 100,000) that would occur if that area had the same age structure as the WHO European Standard Population and the local age-specific rates for that area applied. Confidence intervals for these rates are also presented. Standardised Morbidity Ratios (SMRs) are also included. SMRs express the difference between the observed discharges in each county compared to the expected discharges if the age-specific rates of the national population applied. It is presented as a ratio. A ratio that is greater than 100 indicates that county ...

Colon cancers are thought to be an inevitable result of aging, while testicular cancers are thought to develop in only a small fraction of men, beginning in utero. These models of carcinogenesis are, in part, based upon age-specific incidence data. The specific incidence for colon cancer appears to monotonically increase with age, while that of testicular cancer increases to a maximum value at about 35 years of age, then declines to nearly zero by the age of 80. We hypothesized that the age-specific incidence for these two cancers is similar; the apparent difference is caused by a longer development time for colon cancer and the lack of age-specific incidence data for people over 84 years of age. Here we show that a single distribution can describe the age-specific incidence of both colon carcinoma and testicular cancer. Furthermore, this distribution predicts that the specific incidence of colon cancer should reach a maximum at about age 90 and then decrease. Data on the incidence of colon carcinoma

Community Eye Health or Public Eye Health is one such area.In 1996, I met Dr.LalitDandona who visited Nidadavole village in West Godavari district, where I was posted as a fellow in a rural eye hospital (LVPEI partner hospital).Just after few minutes of discussion with him on my future plans, he immediately offered me a position in the clinical team for the epidemiological study, Andhra Pradesh Eye Disease Study (APEDS), which was coming up few months from then. This study that was undertaken by LVPEI went on for four years (1996-2000) and was a great success resulting in numerous landmark publications in the field of Community Eye Health or Public Health Eye Health as some people ...
