Registers and follow-up methods of populations in a public health survey: the example of the village Glanlé in Ivory Coast.

Demography has a fundamental place in a public health survey, and it is essential to provide the population follow-up. A population exhaustive census is the first compulsory phase. It turns out that this phase is necessary if we want to know with precision the size of the population studied and its main demographic characteristics (sex, age ...). The census allows us to provide a real population follow-up, in order to measure the evolution of the different disorders and to estimate the effects of a prophylaxis on each individual in a precise time. This follow-up requires a computerized population register which contains all the information concerning every individual. This data file is updated with new data collected by next surveys. The realization of the nominal population pyramid, is a complementary tool to the population follow-up. Each individual, characterized by sex and age, is allocated a position in the pyramid by his identification number. The figurative contrasts show several cases noticed according to the studied events. The reconstruction of the genealogy represents another form of the population follow-up, by reconstructing biological kinship relationships between the inhabitants.

Psychiatric hospitalisation and suicide among the very old in Denmark: population-based register study.

BACKGROUND: Very old people have higher suicide rates than the younger elderly population. Psychiatric disorders are known to have a strong association with suicide among elderly people. AIMS: To analyse the analyse the suicide risk associated with psychiatric hospitalisation among the very old (> or =80 years) compared with the middle-aged (50-64 years) and old (65-79 years) populations. METHOD: Individual-level data on the entire Danish population aged 50 years or over were analysed for the period 1994-1998. Relative suicide risks were calculated using event-history analysis. RESULTS: Among 1978 527 persons, 2323 died by suicide. Although the very old group exhibited a four-fold to five-fold increase in risk of suicide for those previously hospitalised, we noted an inverse interaction effect: the increase is distinctly smaller compared with that in the middle-aged and old groups. CONCLUSIONS: The association between suicide and psychiatric hospitalisation is much weaker for the very old than for the old. Psychiatric disorders among very old people may be interacting with other disorders, may be underdiagnosed or treated in other healthcare settings.

A population-based register study of the association between schizophrenia and rheumatoid arthritis.

The authors investigated the association between schizophrenia and rheumatoid arthritis. The design is a population-based case-control and follow-up study. The cases were 20495 patients admitted for schizophrenia and registered in the Danish Psychiatric Case Register. A total of 204912 persons matched on age and gender and chosen from the general population served as controls. Admissions for rheumatoid arthritis and other non-autoimmune, musculoskeletal disorders were checked in the Danish National Patient Register. Odds ratios and relative risks were estimated by the Mantel-Haenszel estimator and Poisson regression. The same analyses were carried out for 10242 patients with bipolar affective disorder and 102420 controls for comparison. Individuals with schizophrenia had a reduced risk for being admitted with rheumatoid arthritis [odds ratio 0.44 (CI 0.24-0.81)] in the case-control study. A similar result was found in the follow-up study, but the incidence of the degenerative disorders in the musculoskeletal system was equally significantly lower in both studies. The incidence of rheumatoid arthritis among the bipolar patients was the same as in the control population. The negative association between schizophrenia and rheumatoid arthritis may thus be the result of ascertainment bias and selection due to under reporting and treatment of the medical illness. Clinicians are reminded of the difficulties in detecting medical illness among individuals with schizophrenia.

Socioeconomic variations in hysterectomy: evidence from a linkage study of the Finnish hospital discharge register and population census.

STUDY OBJECTIVE: To explore variations in rates for hysterectomy in relation to social class, education, and family income. DESIGN: Retrospective analysis of the 1988 Finnish hospital discharge register linked individually to the 1987 population census. SETTING: Finland. PARTICIPANTS: All women living in Finland aged 35 and over were the denominator population. The numerators were the 8663 women who underwent hysterectomy in 1988. MAIN RESULTS: The overall rate for hysterectomy was 63.5/10,000 women aged 35 and over. There was a marked positive correlation between disposable family income and hysterectomy rates even after age, hospital catchment area, education, and occupational status were adjusted for. However, no linear trend for overall hysterectomy rates was observed in relation to social class or education. Procedures due to myomas, accounting for 48% of all hysterectomies, were more frequent among women of high socioeconomic status according to all socioeconomic indicators. Larger proportions of hysterectomies for myoma were also performed in patients in private hospitals and in pay beds in public hospitals than in women in worse off groups. CONCLUSIONS: Unlike the findings in earlier studies from other countries, there was a positive correlation between income and hysterectomy rates as a result of the high numbers of hysterectomies performed to treat myoma in the well off women. The findings are discussed in terms of socioeconomic differences in the use of private gynaecological services, and factors, such as parity and use of hormonal replacement therapy, that affect the growth of myomas.

The risk of endometrial cancer in diabetic and hypertensive patients: a nationwide record-linkage study in Finland.

The risk of endometrial cancer (EC) in diabetics and hypertensives was studied as part of the planning of a trial of the efficacy of screening for EC. Two nationwide registers, the Finnish Cancer Registry and the Social Insurance Institution's (SII) population register, were linked to obtain 1715 EC patients diagnosed during 1970-1974 with individually matched controls. Data on the right for state-reimbursed medication for diabetes or hypertension prior to the case's cancer diagnosis was obtained from the SII's population register and was used as indicator of the diseases in question. Diabetes was a strong and hypertension a relatively weak risk factor for EC. The relative risk for the association of EC with diabetes was 4.1 (95% confidence limits 2.7 and 6.9) and with hypertension 1.6 (95% confidence limits 1.3 and 2.1). Diabetics and hypertensives are identifiable risk groups for EC in Finland. Diabetics form a suitable target population for a trial of the efficacy of screening for EC.

Birthweight and risk of type 1 diabetes in children and young adults: a population-based register study.

AIMS/HYPOTHESIS: We investigated the association between type 1 diabetes and birthweight by age at disease onset. METHODS: This population-based case-referent study used data from two nationwide case registers that are linked to the Swedish Medical Birth Registry and cover incident cases of type 1 diabetes in the 0- to 14-year (since 1 July 1977) and 15- to 34-year age groups (since 1 January 1983). Of the cases linked to the Medical Birth Registry, a total of 9,283 cases with onset before 15 years of age was recorded before 1 January 2003, and 1,610 cases were recorded with onset before 30 years of age and born after 1973 (together 95% of eligible cases). Multiple births and babies of diabetic mothers were excluded. Sex-specific birthweight by gestational week is expressed as multiples of the standard deviation (SDS) and adjusted for year of birth, maternal age and parity. RESULTS: Cases with onset before 10 years of age (n = 5,792) showed a significant linear trend in odds ratio (OR) by SDS of adjusted birthweight (OR by SDS: 0.062; 95% CI: 0.037-0.086; p < 0.0001), while cases with onset at the age of 10-29 years showed no significant trend (OR by SDS: 0.004; 95% CI: -0.007 to 0.0014; p = 0.22). CONCLUSIONS/INTERPRETATION: The association between type 1 diabetes risk and birthweight seems to be limited to cases with disease onset in younger years.

The consistency of shingles and its significance for health monitoring.

Accurate estimation of monitored populations is essential for epidemiological study. Many countries do not have systems of patient registration and routine disease surveillance is thereby hindered. We studied the incidence of shingles over time and investigated the hypothesis that the incidence is consistent and could be used as a proxy for estimating the monitored population. Annual incidence rates of shingles reported in the Weekly Returns Service (WRS) since 1970 and in the Dutch Sentinel Network (DSN) over the period 1998--2001 were studied. Gender specific annual rates (1998--2001) were compared after standardising for age. The population in the DSN was estimated by applying the WRS incidence rates to the numbers of DSN incident cases. The incidence of shingles was annually and seasonally consistent. Incidence in males was similar in both networks and in females approximately 18% greater in the WRS: in age groups 15-64 years, incidence was similar in both networks, but in children 0-14 years and in persons 65 years and over, it was higher in the WRS. The total populations in the DSN estimated from average age/gender specific rates in the WRS were within 12% of the observed in each of the 4 years surveyed. The incidence of shingles in the two countries was sufficiently close to estimate the surveyed population aged 15-64 years from knowledge of incident cases in the community. Routine monitoring of shingles in sentinel practice networks is commended as a method of assuring recording quality and as a means of estimating the survey population where the registered population is not known.

Short- and long-term prognosis after acute myocardial infarction in men versus women.

The prevailing view is that women have a higher early mortality after acute myocardial infarction (AMI) than men, but several studies have shown no differences. Further, long-term differences have not been addressed widely. The present study examined gender differences in short- and long-term prognoses after AMI in The Netherlands. A nationwide cohort of 21,565 patients with a first hospitalized AMI in 1995 was identified through linkage of the National Hospital Discharge Register and the population register. Crude short- and long-term mortalities were significantly higher in women than in men (28-day hazard ratio [HR] 1.70, 95% confidence interval [CI] 1.58 to 1.82; 5-year HR 1.52, 95% CI 1.46 to 1.59). After adjustment for age, the risk difference was attenuated at 28 days and even reversed at 5 years in favor of women (28-day HR 1.11, 95% CI 1.03 to 1.20; 5-year HR 0.94, 95% CI 0.90 to 0.99). When differences in other covariates were also taken into account, the risk differences remained virtually the same. To account for differences in reperfusion procedures, we repeated the analyses in 1,176 patients who underwent acute reperfusion therapy (angioplasty/thrombolysis). Comparable, but not statistically significant, gender differences were observed (28-day HR 1.06, 95% CI 0.65 to 1.74; 5-year HR 0.82, 95% CI 0.62 to 1.08). In conclusion, our findings in an unselected cohort covering a complete nation indicate that the worse short- and long-term prognoses after an AMI in women compared with men may largely be explained by differences in age, whereas differences in co-morbidity, origin, infarct location, and reperfusion therapy seem to contribute little.

Characteristics of 1494 pediatric burn patients in Shanghai.

To analyze the epidemiological characteristics of pediatric burn patients in Shanghai and to determine the targets for a pediatric burn prevention program, a retrospective review of all medical records of acute pediatric burn patients (age</=14 years old) admitted to the Burn Center of the Ruijin Hospital between January 1980 and December 2002 was performed. Patient demographics, etiology of burn, mechanism of injury, extent and anatomical areas burned, number of operations, and length of hospital stay were recorded. A total of 1494 pediatric burn patients were admitted. Six hundred eighty-seven (46%) patients were from the migrant population (non-registered population of temporary workers from rural areas outside of Shanghai). Scalding was the main cause of pediatric burns in the age groups. Children 0-3-year-old were the most common victims of scalding, chemical burns, and contact burns. Domestic burns resulted in 1293 (86.5%) injuries followed by burns occurring while playing in public. The incidence of domestic burns has increased since the beginning of the study period, while the incidence of burns while playing in public has decreased. The median total body surface area was 4% for mild burns, 10% for moderate burns, and 18% for extensive burns. Predominant areas involved were the head, neck, anterior trunk, and right lower limb. Most children received conservative treatment, and their mean hospital stay was 16.1+/-12.2 days. There were 17 (1.1%) deaths, mostly due to sepsis (82.4%). Migrant children are the majority of burn victims since 1996. The education of burn prevention should focus on the migrant population in an industrializing city.

Fertility in Norwegian testicular cancer patients.

The intention was to explore the relationship between fertility and testicular cancer, including the possibly treatment-induced changes over time in the post-diagnostic fertility. Data are from the Norwegian Cancer Registry, The Norwegian Population Register and the Population Censuses. By estimating Poisson regression models, birth rates among testicular cancer patients were compared with those of other men who had the same age, parity and duration since previous birth. Poisson regression models were also estimated to check whether men's parity has an effect on the cancer incidence. Fertility rates among testicular cancer patients born after 1935 and treated before 1991 decreased by roughly 30% when compared with the normal population. The introduction of cisplatin chemotherapy and of nerve-sparing RPLND in the 1980s seems to have enabled more patients with non-seminoma to father a child after treatment, or at least shortened the time to conception. Moreover, the risk of being diagnosed with seminoma is reduced with increasing parity. This suggests that the relatively low fertility after diagnosis may be partly due to the continuing inherent influence of a sub- or infecundity that also had a bearing on the development of the disease.

Epstein-Barr virus infection during pregnancy and the risk of adverse pregnancy outcome.

OBJECTIVES: To study the association between Epstein-Barr virus (EBV) antibody status in early pregnancy and pregnancy outcomes including fetal death, length of gestation and fetal weight and length at birth. DESIGN: Nested control study. SETTING: Population based health registers. POPULATION: The source population comprised 35,940 pregnant women. Cases were all (280) women with fetal death and a random sample of 940 women with a live born child. METHOD: Information on pregnancy outcome was obtained from the Norwegian Medical Birth Registry. Serum samples from the first trimester were tested for EBV antibodies. In women seronegative for EBV, further serum from late pregnancy was analysed to detect seroconversion. Main outcome measures Vital status, length of gestation, weight and length at birth. RESULTS: There was no association between EBV antibody status and fetal death. Women with significant EBV reactivation had a significantly shorter duration of pregnancy, and associated lighter babies, compared with women without significant reactivation (stillborn: 176 vs 197 days, P=0.16, and live born: 271 vs 279 days, P=0.03, respectively). CONCLUSION: Significant reactivation of EBV infection during pregnancy may influence pregnancy duration.

Decline in incidence of hospitalisation for acute myocardial infarction in the Netherlands from 1995 to 2000.

OBJECTIVE: To study the change in incidence of hospitalisation for a first acute myocardial infarction (AMI) in the Netherlands from 1995 to 2000. METHODS: Patients hospitalised with their first AMI in the Netherlands in 1995 and 2000 were identified through linkage of the national hospital discharge register and the population register. RESULTS: 21,565 patients hospitalised for their first AMI in 1995 and 19,058 patients hospitalised for their first AMI in 2000 were identified. In both years, the age specific incidence of hospitalisation for a first AMI was higher in men than in women and increased with age (up to 90 years). In both men and women, the age standardised incidence was lower in 2000 than in 1995, a decline of 19% (95% confidence interval 17% to 21%) and 17% (95% confidence interval 14% to 19%), respectively. CONCLUSIONS: Our study provides the first nationwide incidence estimates of first AMI in the Netherlands. From 1995 to 2000, the risk of AMI declined considerably.

Dental visiting patterns of Finns and Swedes in Sweden, 1976-1980.

Information on treatment provided to a random (cluster) sample of all adult patients treated under the dental insurance scheme in Sweden since 1974 is stored at the National Social Insurance Board (NSIB). In this study the use of dental services by settled Finnish immigrants and Swedes over a 5-year period (1976-80) was compared, using this information. The material consisted of 1152 17- to 64-year-old Finnish immigrants, selected in accordance with the same criteria as the NSIB sample, registered on the population register of Stockholm county in 1975 and still on the register in 1982, and a comparison group of individually matched Swedes. Standard NSIB computer programs and a special program for recurrent use of dental services in 1976-79 were used. Because of regulations on confidentiality of personal information, comparisons were based on inter-group differences. Each year about 40% of Finnish immigrants and 50% of Swedes had been to a dentist. In both groups women visited a dentist more frequently. The proportion of persons in the different groups who had used dental services in the period 1976-80 varied only slightly from year to year. In the 4-year period 1976-79, 74% of Finnish immigrants and 87% of Swedes in the studied groups had been to a dentist at least once. Significantly more Swedes than Finnish immigrants had seen a dentist annually. Of those who had been to a dentist, a significantly greater proportion of Finnish immigrants than Swedes had received acute treatment and dentures.(ABSTRACT TRUNCATED AT 250 WORDS)

A population-based register study of vaccine coverage among children in Greenland.

To assess coverage rates of standard childhood vaccinations in Greenland, a geographically isolated and sparsely populated area, and to determine risk factors for low coverage, we performed a register-based cohort study among 596 children from 1993 to 1998 in Sisimiut, Greenland. For vaccines given before the age of 2 years (pertussis 1-3, DT-IPV 1-3, and MMR 1) coverage rates in general were impressively high being on or above levels of Western countries. A risk factor for low coverage was migration. The Greenlandic vaccination model with free vaccinations administered by health workers who systematically call in children at scheduled times seems highly efficient and could be a model for other similar countries.

Aldosterone to Renin ratio in a primary care setting: the Bussolengo study.

The aim of the study was to evaluate the prevalence of hypertension associated with an elevated aldosterone to renin activity ratio (ARR) in a sample of adults aged 35-74 yr, randomly selected from the population register of the Bussolengo Health District (northern Italy) and representative of the total population of the district. Subjects (n = 1462) were randomly selected from the population register and examined by their general practitioners. Complete data for 1348 individuals were available for final statistical analysis. Apart from verapamil or alpha-blockers, no hypotensive drugs were allowed during the 4 wk before assay. Direct active renin and aldosterone were measured in the plasma of hypertensive patients after 2 h in the upright posture. Of 412 identified hypertensive patients, 287 subjects agreed to give blood (70% response rate). An aldosterone to active renin ratio (AARR) of 32 pg/ml was taken as the cut-off value, equivalent to an ARR of 50 ng/dl/ng/ml.h. An elevated AARR was observed in 32.4% of the hypertensive patients, with increased prevalence in females and in people aged 55 yr or older. As an elevated AARR is frequent in the general hypertensive population, screening should not be limited to the patients referred to specialist units.

Dementia care needs in an area population: case register data and morbidity survey estimates.

OBJECTIVE: To compare case register data on the frequency and distribution of known dementia cases in a metropolitan area population with expected total numbers computed from a national disability survey. METHOD: Known cases were enumerated by a cross-sectional census of the Camberwell Dementia Register. Expected total numbers were calculated using the Cognitive Disability (CD) Planning Model, based on the OPCS national survey of disability, 1985-86. RESULTS: Cases ascertained by the Dementia Register census comprised one-fifth of expected total prevalence. The proportion of such cases was higher for persons in long-stay care (1 in 3) than for those in private households (1 in 7). According to the CD Planning Model, cases known to specialist agencies were on average no more severely disabled and dependent than those who were unknown. In terms of absolute numbers, the district nursing and home help services appeared to be the most important untapped sources of case detection, but other research indicates that general practice contacts (not included in the planning model) may be at least equally important. CONCLUSIONS: At any given time, a high proportion of dementia cases, whether in long-stay care or in the community, will be outside the purview of specialist services. Primary care agencies are a major potential source, and a systematic health screening of persons aged over 75 years could be used to realize this potential.

A comment on the reference series with regard to multiple exposure evaluations in a case-referent study.

Case-referent (case-control) studies permit multiple exposures to be considered within the same series of cases and referents (controls) with regard to the etiologic contribution to a certain disease. Specific aspects of validity should be considered however, one being the utilization of an adequate reference series. Should the exposure cause, prevent, or otherwise have a certain relationship to disorders other than the one being studied, individuals with such other disorders cannot be uncritically included in the reference series if obtained from a hospital register, a register of causes of deaths, or some other source of subjects with relations to the individuals' health status. If a general population register is utilized, this problem is avoided since individuals obtained from such a register would adequately reflect the exposure frequency of the source population of the cases. These aspects are well illustrated by a consideration of the use of drugs among cases and, on one hand, referents with some sort of disorder as compared to referents (whether healthy or not) obtained from a population register on the other hand. Studies of industrial exposures seem to be somewhat less sensitive to bias of this type however, since industrial exposures are not primarily disorder-related, whereas drug exposures are.

The accuracy of age-sex registers, practice medical records and family practitioner committee registers.

This paper presents the results of a point prevalent evaluation of the comparative reliability and validity of age-sex registers, practice medical records and family practitioner committee (FPC) registers from five teaching practices. They all exhibited similar levels of acceptable accuracy for patient names, sex and age, but the distribution of wrong addresses varied greatly: practice medical records 3.9 per cent, age-sex registers 8.2 per cent and FPC registers 17.1 per cent. The presence of a patient entry in all three registers was associated with a high degree of probability (95.3 per cent) that this individual would be a bona fide practice patient. The register population inflation rates were FPC records 5.5 per cent, practice records 9.8 per cent and age-sex registers 10.6 per cent, but there were large variations between individual practices. A statistically significant contribution to inflation rates came from the age groups 0 to 1 and 21 to 40 (p<0.0005). The register population deflation rates were minimal. The significance of these findings is discussed and the need for practices to determine the accuracy of their individual age-sex registers is stressed. A convenient and economic method for so doing is suggested. We also suggest ways of making it easier to construct and use age-sex registers, since they can be a most versatile and useful aid to research in general practice.
