Mortality differentials among Israeli men.

OBJECTIVES: This study examined differentials in mortality among adult Israeli men with respect to ethnic origin, marital status, and several measures of social status. METHODS: Data were based on a linkage of records from a 20% sample of the 1983 census to records of deaths occurring before the end of 1992. The study population included 72,527 men, and the number of deaths was 17,378. RESULTS: Differentials is mortality by origin show that mortality was higher among individuals of North African origin than among those of Asian and European origin. After allowance for several socioeconomic indicators, the excess mortality among North African Jews was eliminated. Substantial and consistent differences in mortality were found according to education, occupation, income, possession of a car, housing, and household amenities. Differentials among the elderly were markedly narrower than those among men younger than 70 years. CONCLUSIONS: Some sectors of Israeli society have higher risks of death than others, including, among the male population, these who are poor, less educated, unmarried, unskilled, out of the labor force, and of North African origin.

The Israel Longitudinal Mortality Study--differential mortality in Israel 1983-1992: objectives, materials, methods and preliminary results.

The main objective of this study was to investigate mortality differentials in the Israeli population, aged 40 years and above, with regard to major demographic and socio-economic characteristics, in the nine-and-a-half years following the census of 1983. The method of data collection consisted of a linkage of records from the 20% sample of the census with the records of deaths occurring until the end of 1992. The linked file contains the socio-economic and demographic data from the census, and dates and causes of death taken from the death records. This paper focuses on a systematic evaluation of the quality of the linked file, and includes a description of the characteristics of the file. Methods of verification are presented and sources of possible errors are discussed. Results of bivariate analyses of mortality differentials in relation to marital status, ethnic origin, level of education, employment, occupation and income are presented.

Potential demography: a second look.

"In the late forties Hersch (1944) and Mentha (1948) introduced, respectively, the concepts of 'potential years of life' (PYL) and 'potential years of life lost' (PYLL).... Our objectives are: (a) to draw attention to Hersch's concept of potential years of life (PYL) and to illustrate its usefulness; (b) to define and illustrate three different manners of computing PYLL and to recommend one that is simple, intuitively acceptable and reasonably accurate; (c) to propose some further indicators that can be derived from PYL, PYLL and the relations between them; and (d) to discuss briefly the assumptions underlying the calculation of PYL and PYLL, and in particular those assumptions that are made in the attribution of loss in potential years of life to specific risk factors."

Correlates of military tank simulator sickness.

A military tank driving simulator is currently widely used as a training aid for tank drivers. The purpose of this study was to investigate the relationship between possible correlates of simulator sickness and the occurrence of sickness and performance test results among simulator drivers. The average number of motion sickness-like symptoms reported after driving the simulator among subjects with a history of susceptibility to motion sickness was 3.4, significantly higher than the average of 1.6 reported among subjects who did not report previous susceptibility to motion sickness (p < 0.05). Subjects driving the simulator while screen image quality was disturbed had a longer reaction time (42.0 s) than when driving the simulator without screen interferences (18.4 s, p = 0.001). Subjects driving the simulator for a short period had the same number of symptoms as did those driving for a longer period, but had better digit symbol test results. There was no statistically significant association between the development of sickness and tank driving experience. Suggested countermeasures are expected to prevent simulator sickness among some of the simulator trainees and to make simulator training more effective.

Estimated number of loci for autosomal recessive severe nerve deafness within the Israeli Jewish population, with implications for genetic counseling.

Deafness occurs in about 1 per thousand live births, and at least 50% of congenital deafness is hereditary. The aim of this study was to examine the number of loci for recessively inherited severe nerve deafness of early onset within the Israeli population and to compare the results to those obtained in other populations. The Jewish population in Israel originates from many countries and may be divided into Sephardi, Eastern and Ashkenazi Jews, and the matings will be intraethnic or interethnic. Data were obtained on 133 deaf couples who lived in the Tel Aviv area, through the files of the Helen Keller Center. Causes of deafness in the spouses were studied and data on their children were obtained. Among 111 couples who had recessive or possibly recessive deafness and had at least 1 child, there were 12 with only deaf children and 5 with both deaf and hearing children. The number of loci for recessive deafness in the whole group was estimated at 8-9. Intraethnic and interethnic matings gave an estimate of 6.7 and 22.0 loci, respectively, which indicates that within populations fewer loci exist with recessive mutations for deafness than between populations. It could be shown that the sharing of loci between spouses decreased with increasing geographical distance of their origin. The results provide data for genetic counseling in Israel for deaf couples who have no children or have one hearing or one deaf child.

An epidemiologic study of mortality among bereaved parents.

To study the health consequences of parental bereavement, we compared the mortality in two groups of bereaved Israeli parents with that in the general population. One cohort comprised the parents of all 2518 soldiers 18 to 40 years of age who were killed during the Yom Kippur War in 1973. The second consisted of the parents of 1128 men 18 to 30 years of age who died in accidents between 1971 and 1975. Both groups were followed through 1983. The comparison population was the entire population of Jewish Israelis for which sex-, age-, and calendar year-specific mortality rates were available. The 10-year age-adjusted life-table mortality was higher among fathers whose sons died in accidents rather than in war (P = 0.045), but mortality did not differ significantly between the two groups of mothers. Overall, we found no excess mortality among the bereaved parents as compared with the general population. The standardized mortality ratios for the fathers and mothers of sons killed at war were 0.91 and 0.90, respectively; for fathers and mothers whose sons died by accident, they were 1.04 and 0.91, respectively. None were significantly different from unity. There was no consistent evidence of an elevated risk of death, early or late, after the loss. Widowed and divorced parents who lost a son did have increased mortality, which was statistically significant in mothers. Our findings provide no support for the hypothesis that the loss of an adult son is associated with increased short-term or long-term mortality in married parents.

Rates of sickness absenteeism among employees of a modern hospital: the role of demographic and occupational factors.

Sickness absenteeism, of hospital employees particularly, is a problem of concern due to its negative economic and morale impacts. The aim of the first stage of the study was to identify according to some demographic (sex, age, marital status) and occupational (occupational group, duration of hospital employment) variables those groups of hospital employees who are at higher risk of sickness absenteeism. A comparison with the data of the study performed in the same hospital about 15 years ago showed a rise in the duration of absences with a simultaneous reduction in their incidence. Sickness absenteeism was higher among female, mainly unskilled, workers, presently or previously married, aged from 45 to 60, and employed in the hospital for over ten years. Continuous social and medical surveillance of these employees is suggested as a promising way of reducing sickness absenteeism.

Berkson's bias revisited.

When used in a loose manner to indicate distortive effects on associations among hospitalized patients, the term Berkson's bias denotes a special case of Simpson's paradox. If, however, Berkson's independence assumption is introduced, Berkson's bias affects only the "selected" subjects and not those "left behind" and tends to decrease the odds-ratio. Generally speaking, the model is valid not only for case-control studies but also for prospective and other investigations. By introducing a time dimension the model allows for the study of changes over time in Berkson's bias.

Risk markers for mortality among elderly men-a community study in Jerusalem.

Risk markers for mortality among elderly men were investigated in a community survey in a neighborhood of western Jerusalem. The aim was to develop a practical method of identifying men with a high risk of mortality, for use in community health services caring for the ageing and aged. Men aged 60 yr or more who had been interviewed and examined in 1969-71 were followed up for 5 yr and the characteristic of the 75 who died were compared with those of the 312 who remained alive. The results of stepwise discriminant function analyses were translated into a simple set of criteria for the identification of men with a high risk of dying within 5 yr. The sensitivity of this mortality risk indicator hazard in this sample was 72% and its specificity was 78%. The components were age, inability to work, impaired mobility, impaired memory for recent events, electrocardiographic evidence of coronary heart disease, the presence of moderate or severe illness, diastolic hypertension, hypercholesterolemia and overweight.

Clustering of chronic disorders--a community study of coprevalence in Jerusalem.

Associations between chronic disorders were appraised in a community survey in western Jerusalem in order to identify clusters of mutually related conditions. Two sets of interrelated diseases were observed. The first comprised coronary heart disease, hypertension, diabetes and their complications. The second included migraine and other chronic disorders whose diagnosis was largely based on subjective symptoms. The presence of these complaint-based disorders was associated with a high prevalence of emotional symptoms, with reported difficulties in the life situation, and with frequent doctor visits. The design of appropriate programs of preventive and therapeutic intervention for this cluster of disorders remains an important challenge.

Clustering of Hodgkin's disease in Israel: a case-control study.

The geographical distribution of Jewish patients in Israel with HD diagnosed between 1960 and 1972 differed significantly from that of individually-matched population controls. Significant clustering occurred in 3 regions of the country. The odds ratio expressing the greater tendency of patients to have lived in one of these regions 5-9 years before the diagnosis, as compared with that of their paired controls, was 2.4. The association with residence in a higher-risk region was not significantly modified by sex, age, period of immigration, region of birth, father's region of birth, or date of diagnosis. The association was weaker for cases with nodular sclerosis than for those with other subtypes of HD. The clustering could not be explained by available data on the characteristics and prior experience of the cases and controls. There was a significant correlation between the risk of HD in a region and the proportion of native Israelis in its Jewish population, but there were no significant correlations with a variety of other demographic, natural and socioeconomic features of the regions. There was no significant time-space interaction. The findings suggest that susceptible people living in certain parts of the country during the 1950's and 1960's had a somewhat enhanced risk of HD because of exposure to unidentified environmental factors active in those regions at that time.

A community health study in Jerusalem. Design and response.

A longitudinal community health study was commenced in a neighborhood of western Jerusalem in 1969. Its main aims were the investigation of etiologic factors in selected common diseases and disabilities, the development and testing of epidemiologic tools for use in community diagnosis, the provision of a factual basis for decisions concerning community health care for the population studied, and the use of the findings in an evaluation of the effectiveness of community health care. In the first round, 90% of residents 25 or more years old were interviewed and 81% were examined. Among children under 15 years of age, the corresponding rates were 94 and 83%. Response was low among persons in the age range 15 to 24 years, especially males. People who were concerned about their health were readier to be examined. Response was not related to region of birth, education or other variables. The possible bias introduced by nonresponse appeared to be small except in the age group 15 to 24 years.
