Hip fractures in the county of Funen, Denmark. Implications of demographic aging and changes in incidence rates.

In patients 40 years and above a total of 3096 hip fractures (783 in males and 2313 in females) occurred in the entire county of Funen, Denmark from 1 July 1973 to 30 June 1979. The incidence of hip fractures increased exponentially with age in both sexes. During the survey the number of hip fractures in females showed a marked increase above what could be explained by demographic aging alone, whereas this tendency was not so pronounced in males. Provided the observed increase in incidence rates prevails, aging of the population in combination with this increase will lead to a threefold increase in the number of hip fractures over a 20-year period. This is substantially more than other Scandinavian authors have reported.

Tubal sterilization in women 15-24 years of age: demographic trends in the United States, 1970-1980.

Between 1970-1980, approximately 942,000 women 15-24 years of age underwent tubal sterilization in the United States. These women represented about 17 per cent of all women ages 15-44 years who underwent tubal sterilization in the United States during this 11-year period. During 1970-1980, sterilization rates rose steadily from three per 1,000 to 11 per 1,000 for women in the 20- to 24-year age group, but remained stable at less than one per 1,000 for women in the 15- to 19-year age group. For each year, rates for Black women were greater than those for White women. Sterilization rates increased over the time period for both currently and previously married women, but remained low for never-married women. Most tubal sterilizations were performed after delivery of an infant.

[Spatial pattern and consequences of demographic aging processes for regional planning].

The spatial dimension of man-environment interactions in old age is analyzed within urban, suburban, and rural residential environments of the German Rhine-Main-Agglomeration. By comparing the three levels of organization, utilization, and interpretation, housing conditions as well as geographical distribution and redistribution (migrations) our outside-home-activities and environmental perception show a fundamental influence on the everyday lives of the 750 elderly who were interviewed. The majority of the target population and, especially, the rural elderly is characterized by traditional patterns of spatial organization and distribution, mobility, regional attachment, and a concern about preserving the stability of their current residential environment from changes. The suburban and urban seniors, however, exhibit a greater amount of locational flexibility and utility-oriented behavior patterns. These spatial variations are induced by specific regional values and intensity of local and regional identification. They might be interpreted as different stages in the process of modernization within postindustrial societies. Reflecting, however, the paradigms of planning for the elderly, these different patterns are not systematically considered to the necessary and sufficient extent. Instead of promoting regional or local networks that are favored by senior citizens, agencies usually prefer comprehensive approaches on a macrolevel. First steps to improve this situation and to combine life- and system-world demands have been taken by the federal government, which implemented a neighborhood-related research program on housing for the elderly. As a result of this, further research on environmental aspects on aging should pay more methodological attention to the hitherto neglected regional and local level, and also for the transfer of its findings into planning policy.

Some determinants of attrition in prospective studies on aging.

Demographic measures, psychosocial variables, and objective and subjective measures of physical impairment were assessed in elderly men twice at intervals of 12 to 18 months. Canonical discriminant function analysis of the relationship between these predictor variables on the first testing and whether participants (a) returned for retesting, (b) did not return because of apparent disinterest, or (c) did not return because of illness or death, revealed two significant canonical variates. The first, characterized by decreased mental and physical capacity, discriminated between the deceased/ill group and the other two groups. The second was characterized by decreased social interaction and life satisfaction, and increased life events, and distinguished between the disinterested group and the other two groups. However, both groups that failed to return for retesting showed evidence of impaired physical health and a general disengagement from social and personal activities, compared to the retested group.

[Skeletochronological determination of age and demographic analysis of a population of Acanthodactylus pardalis (Lischenstein, 1823) of the Kerkennah islands (Tunisia)].

The skeletochronological analysis of 34 adult lizards from population of Acanthodactylus pardalis of Kerkennah islands in Tunisia enabled to: determine the individual age of the animals; delineate four various cohorts making up the studied population; evaluate around 4 years life span in nature of this species; point out that the renewal rate accounts for 41% of its population. Moreover the method of "maximums successifs" is applied on sizeable sample in order to shore up the obtained results.

An overview of relevant data sources in the former USSR for studies in demographic trends, aging and noncommunicable disease problems.

This article provides an overview of health data available in the former USSR. It is not all-inclusive in terms of chronic diseases covered or in details of data collection activities carried out. However, several broad conclusions can be drawn: There is a system of population and mortality data collection which covers the former USSR and which can be disaggregated to smaller administrative areas. The system is being exploited by population specialists, demographers, medical demographers and epidemiologists, both nationally and internationally, both for analytical purposes and as part of health monitoring systems. A national-level data-collection system for morbidity and disability, based on delivery of health services, is in place and is exploited by both health researchers and health planners. The shortcomings of such a health service-based statistical system are well recognized. Further standardization or calibration of measures of total and cause-specific morbidity and disability measures should be examined. A potential calibration tool is the 1988-1993 health examination and interview survey covering a representative (but highly clustered) sample of the former USSR population. The possibilities of greater standardization of measurement procedures used in this survey should also be investigated. In certain disease areas, e.g. cardiovascular diseases, cancer, rheumatic diseases and gerontology, clinical and epidemiological studies involving international collaboration have been carried out. This has resulted in the use of internationally accepted disease definitions, diagnostic procedures, and of clinical and laboratory standardization of demographic, social and biological measurements. Participation in multilateral or bilateral studies should be encouraged in research in disease areas where these types of programmes have not yet been instituted.(ABSTRACT TRUNCATED AT 250 WORDS)

Burns in school-age children: demographics and burn prevention.

Epidemiologic and demographic study of burn center patients and admission patterns can be useful in tailoring burn prevention programs. Such studies can pinpoint specific high-risk areas and seasons, thus allowing more efficient expenditure of resources.

[Occupational rehabilitation of workers of older age groups].

In the conditions of the demographic aging of the population in the USSR, both medical and social inadequacy of the existing system of technocratic management in industries is becoming still more apparent. What is needed now is humanization of industry by adjusting it to the actual functional abilities of the aging workers on an individually typical basis.

Screening for neurofibromatosis type 1-related optic pathway gliomas: a systematic review.

BACKGROUND: Neurofibromatosis-type 1 (NF1) is a genetic disorder characterized by developing optic pathway gliomas (OPGs) in 15%-20% of patients with higher estimates where consanguinity is prevalent. Clinically, NF1-OPG might be unpredictable with the risk of OPG progression and visual impairment. The optimal time for screening is controversial. We aim to identify the mean/median age at diagnosis of NF1-OPG and its clinical spectrum. METHODS: A systematic review of PubMed, Web of Science, and Embase databases was conducted for English-language publications from January 1993 to October 2025, exploring the visual screening of OPGs in NF1 patients, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and registered in the Prospective Register of Systematic Reviews (PROSPERO ID: CRD420251036244). Inclusion criteria focused on studies reporting the age at OPG diagnosis and visual manifestations in NF1 patients. Data were extracted on demographics, age at NF1 and OPG diagnosis, tumour location (using the Dodge classification), and presenting symptoms. Sixteen studies met the inclusion criteria. RESULTS: Among 4 739 NF1 patients, 818 had OPGs, with prevalence ranging from 4.2% to 46.7%. The age at NF1 diagnosis ranged from 0 to 132 months (mean: 18-38 months), and at OPG diagnosis from 0-240 months (median: 29-58 months). Approximately 58.4% of OPGs were asymptomatic, and 25% were above the age of 5 years. Among symptomatic patients, the most frequent presentations included decreased visual acuity (62%), abnormal optic disc (45%), proptosis (20%), strabismus (12%), and visual field defects (7%). CONCLUSIONS: NF1-related OPGs typically present early within 6 years of age. Early ophthalmologic and/or radiologic screening at the time of NF1 diagnosis enhances the detection of silent OPGs.
