Clinical characteristics of multiple sclerosis in Västerbotten County in northern Sweden.

BACKGROUND: Most clinical data for multiple sclerosis are hospital based-that is, derived from patients referred to clinics specialising in the disease. OBJECTIVES: To present data derived from two population based multiple sclerosis populations, an incidence cohort and a prevalence population, from Västerbotten County, northern Sweden. METHODS: The two populations were identified from multiple sources, and case ascertainment was assured through a personal clinical review, including interviews and examination of the patients. RESULTS: Characteristics at onset for the different clinical subtypes of multiple sclerosis are presented, including the clinical spectrum of the first attack, the anatomical correlation between the first and second attacks, sex distribution, and disability distribution. CONCLUSIONS: Based on the comparison of present and earlier natural history data, multiple sclerosis appears to be a slightly more benign disease than previously recognised.

A prospective study of asthma incidence and its predictors: the RHINE study.

The objective of this longitudinal study was to estimate the incidence rate of asthma, and to compare the incidence between subjects with or without baseline reporting of certain respiratory symptoms. A follow-up of the random population samples in the European Respiratory Health Survey (ECRHS) in Sweden, Norway, Denmark, Iceland and Estonia was conducted in 1999-2001, in a population aged 30-54 yrs at follow-up (n=14,731). Asthma was defined as reporting either asthma or physician-diagnosed asthma, and a reported year when asthma symptoms were first noticed. Incidence rates, incidence rate ratios and hazard ratios were calculated with 95% confidence intervals. The incidence rate of asthma was 2.2 cases per 1,000 person-yrs. The incidence was higher among females (2.9 cases.1,000 person-yrs(-1)) than among males (1.5 cases.1,000 person-yrs(-1)). When subjects with baseline reporting of wheezing were excluded, the incidence rate decreased to 1.7 cases.1,000 person-yrs(-1), with a further decrease to 1.5 cases.1,000 person-yrs(-1) after exclusion of subjects with wheezing, nocturnal dyspnoea, chest tightness and cough. There was a strong association between onset of asthma and wheezing at baseline. In this prospective, population-based study, the incidence rate of asthma in the whole population sample ranged 1.5-2.2.1,000 person-yrs(-1), with a higher incidence range among females. The incidence was dependent on the extent to which subjects with respiratory symptoms were excluded from follow-up. Hence, for comparability between studies, the exclusion criteria in the follow-up population must be stated.

Evaluation of the new ADA and WHO criteria for classification of diabetes mellitus in young adult people (15-34 yrs) in the Diabetes Incidence Study in Sweden (DISS).

AIMS/HYPOTHESIS: We aimed to evaluate how an aetiology-based classification, as recommended in the ADA and WHO guidelines for classification of diabetes mellitus, matches clinical judgement in the Diabetes Incidence Study in Sweden (DISS), a study covering incident cases of diabetic patients aged 15 to 34 years. METHODS: During a 1-year period (1998), blood samples were taken at diagnosis and 4 months (median) thereafter. Patients were classified according to clinical judgement by the reporting physicians and assessments of islet antibodies (ICA, GADA, and IA-2A) and plasma C-peptide. RESULTS: In 1998, 422 patients were registered in DISS. Among the 313 patients participating in the follow-up, most with clinical Type 1 diabetes (185/218, 85%, 95% CI 79-89%) were islet antibody positive (ab+) at diagnosis. In addition, 14 out of 58 (24%, 14-37%) with clinical Type 2 diabetes and 21 out of 37 (57%, 40-73%) with unclassifiable diabetes were antibody positive at diagnosis. Further to this, 4 out of 33 (12%, 3-28%) were antibody negative with clinical Type 1 diabetes and 4 out of 44 (9%, 3-22%) with Type 2 had converted to antibody positive at follow-up. Among those who were constantly antibody negative, 10 out of 29 (34%, 18-54%) with clinical Type 1 and 1 out of 16 (6%, 0-30%) with unclassifiable diabetes had fasting plasma C-peptide concentrations below the normal range (<0.25 nmol/l) at follow-up. CONCLUSION/INTERPRETATION: Most young adults with clinical Type 1 diabetes (199/218, 91%) had objective Type 1 (ab+ at diagnosis/follow-up and/or low fasting plasma C-peptide concentrations at follow-up), as did one third (18/58, 31%) with clinical Type 2 diabetes and more than half (22/37, 59%) with unclassifiable diabetes. About 10% of those who were antibody negative converted to antibody positive. Our study underlines that a classification considering aetiology is superior to clinical judgement.

Service screening with mammography. Long-term effects on breast cancer mortality in the county of Gävleborg, Sweden.

In the current study the long-term effects of a pilot service screening programme in the Swedish county of Gävleborg were studied. Women aged 40-64 years in 13 sub-areas were followed from start of screening between 1974 and 1979. Two control groups were used for comparison; the neighbouring counties and all of Sweden. A reference period prior to the study period was used to facilitate an adjustment for possible differences in baseline breast cancer mortality. Only deaths from breast cancer diagnosed after the first invitation to screening were analysed. Two outcome measures were used for breast cancer mortality; the underlying cause of death and excess mortality. Using the neighbouring counties as a control group, the relative risk, after 22 years of follow-up, of 10 years of screening was estimated at 0.84 (95% CI 0.71-1.00) using excess mortality. Due to lead time bias the relative risk was overestimated by 4%. Hence, a significant 20% reduction of breast cancer excess mortality was found.

Increasing body mass index at diagnosis of diabetes in young adult people during 1983-1999 in the Diabetes Incidence Study in Sweden (DISS).

OBJECTIVE: To study trends in body mass index (BMI) at diagnosis of diabetes in all young Swedish adults in the age range of 15-34 years registered in a nation-based registry. DESIGN: The BMI was assessed at diagnosis in diabetic patients 15-34 years of age at diagnosis, for a period of 17 years (1983-1999). Islet cell antibodies (ICA) were measured during three periods (1987-1988, 1992-1993 and 1998-1999). SETTING: A nationwide study (Diabetes Incidence Study in Sweden). SUBJECTS: A total of 4727 type 1 and 1083 type 2 diabetic patients. MAIN OUTCOME MEASURES: Incidence-year specific BMI adjusted for age, gender and time of diagnosis (month). RESULTS: Body mass index at diagnosis increased significantly both in type 1 (21.4 +/- 3.6 to 22.5 +/- 4.0; P < 0.0001) and in type 2 (27.4 +/- 6.8 to 32.0 +/- 6.0; P < 0.0001) diabetic patients, also when adjusted for age, gender and month of diagnosis. A similar significant increase in BMI was found in type 1 diabetic patients and in type 2 diabetic patients in the periods 1987-1988, 1992-1993 and 1998-1999; years when ICA were assessed and considered in the classification of diabetes. Despite this increase in BMI, there was no increase in the incidence of diabetes in young-adult people in Sweden. CONCLUSION: Body mass index at diagnosis of diabetes in subjects 15-34 years of age has substantially increased during 1983-1999 in Sweden when adjusted for age, gender and month of diagnosis.

Children born in the summer have increased risk for coeliac disease.

STUDY OBJECTIVE: Coeliac disease, also called permanent gluten sensitive enteropathy, is being recognised as a widespread health problem. Defining the possible role of environmental factors in its aetiology might open doors to primary prevention. This study therefore analysed if the risk for coeliac disease varies with month of birth as a proxy for a seasonal pattern for possible causal environmental exposure(s). DESIGN: A population based incidence register of coeliac disease in children below 15 years of age covering the period from 1973 to 1997. Incidence rates were calculated by month of birth, stratified for age at diagnosis. Poisson regression analyses were used to estimate the relative risk for coeliac disease for children below 2 years of age by season of birth, also taking into account gender and time period of diagnosis. SETTING: Sweden. PARTICIPANTS: All 2151 children in the study base with verified coeliac disease. MAIN RESULTS: The risk for coeliac disease was significantly higher if born during the summer as compared with the winter (RR=1.4, 95% CI 1.2 to 1.7), but only in children below 2 years of age at diagnosis. This relative seasonal risk pattern prevailed during a 10 year epidemic of coeliac disease, although incidence rates varied threefold. The incidence was constantly higher among girls as compared with boys, but boys showed a more pronounced seasonal variation in risk than girls. CONCLUSIONS: An increased coeliac disease risk in children born in the summer compared with the winter reflects causal environmental exposure(s) with a seasonal pattern. Infections might be the exposure of importance, either by means of a direct causal role and/or through interaction with other exposures, for example, gluten intake. However, non-infectious exposures should also be explored as possible contributing causal factors.

Incidence (1988-97) and prevalence (1997) of multiple sclerosis in Västerbotten County in northern Sweden.

OBJECTIVE: To investigate the incidence and prevalence of multiple sclerosis in Västerbotten County in northern Sweden. METHODS: Multiple sources were used in the case identification process. Follow up interviews with clinical examinations were undertaken and, when indicated, additional paraclinical investigations were done. In this way case ascertainment was assured and supplemental clinical data were collected. The incidence rate was based on symptom onset. Onset adjusted prevalence was applied. RESULTS: The crude incidence rate of multiple sclerosis in 1988-97 in Västerbotten County was 5.2/10(5) (95% confidence interval, 4.4 to 6.2): 6.7/10(5) (6.0 to 8.3) in women and 3.7/10(5) (2.7 to 4.9) in men. The onset adjusted prevalence for 31 December 1997 was 154/10(5) (139 to 170): 202/10(5) (179 to 228) in women and 105/10(5) (89 to 125) in men. When compared with a previous estimate of prevalence, a yearly 2.6% increase in prevalence between 1990 and 1997 was found, mainly attributable to a higher incidence than mortality. CONCLUSIONS: The present incidence rate and prevalence confirms earlier findings that Västerbotten is a high risk area for multiple sclerosis. The adjusted incidence was twice as high as the incidence from 1974-88 in the only previous Swedish population based study from Göteborg, but comparable with other recent Fennoscandian multiple sclerosis incidence rates.

Sick leave and professional assistance for multiple sclerosis individuals in Västerbotten County, northern Sweden.

The aims of this study of a cross-sectional multiple sclerosis (MS) population in Västerbotten County, northern Sweden, were to estimate the prevalence of sick leave, professional assistance and housing; to study risk factors for sick leave; and to estimate the odds for sick leave in comparison with the general population of the county. The consequences of MS-related incapacity on the socioeconomic factors studied were considerable. Almost half (45%) of prevalent MS cases aged 18-64 years were fully sick listed and only one-third (35%) were not sick listed at all. Every fourth individual in the prevalence population received professional assistance, and 9% were living in care homes or special apartments for the disabled. Multiple logistic regression analysis identified the Expanded Disability Status Scale (EDSS) as the strongest predictor of sick leave. The time from symptom onset to full sick leave leading to temporary or permanent disability pension was significantly shorter for cases with progressive onset, higher age at onset and in males. The risk of full sick leave due to MS was six times higher than in the general population.

The incidence of Type I diabetes has not increased but shifted to a younger age at diagnosis in the 0-34 years group in Sweden 1983-1998.

AIMS/HYPOTHESIS: To analyse the incidence of Type I (insulin-dependent) diabetes mellitus in the 0-34 years age group in Sweden 1983-1998. METHODS: Incidence and cumulative incidence per 100 000 and Poisson regression analysis of age-period effects was carried out using 11 751 cases from two nation-wide prospective registers. RESULTS: Incidence (95%-CI) was 21.4 (20.8-21.9) in men and 17.1 (16.6-17.5) in women between 0 and 34 years of age. In boys aged 0-14 and girls aged 0-12 years the incidence increased over time, but it tended to decrease at older age groups, especially in men. Average cumulative incidence at 35 years was 748 in men and 598 in women. Cumulative incidence in men was rather stable during four 4-year periods (736, 732, 762, 756), while in women it varied more (592, 542, 617, 631). In males aged 0-34 years, the incidence did not vary between the 4-year periods ( p=0.63), but time changes among the 3-year age groups differed ( p<0.001). In females the incidence between the periods varied ( p<0.001), being lower in 1987-1990 compared to 1983-1986, but time changes in the age groups did not differ ( p=0.08). For both sexes median age at diagnosis was higher in 1983-1986 than in 1995-1998 ( p<0.001) (15.0 and 12.5 years in males; 11.9 and 10.4 in females, respectively). CONCLUSION/INTERPRETATION: During a 16-year period the incidence of Type I diabetes did not increase in the 0-34 years age group in Sweden, while median age at diagnosis decreased. A shift to younger age at diagnosis seems to explain the increasing incidence of childhood Type I diabetes.

Labor induction with vaginal misoprostol and extra-amniotic prostaglandin F2alpha gel.

OBJECTIVE: To compare the effectiveness of vaginally administered misoprostol with extra-amniotic prostaglandin F2alpha (PGF2alpha) gel for induction of labor. METHOD: A randomized controlled trial, with women allocated to receive either misoprostol 50 microg intra-vaginally or extra-amniotic PGF2alpha gel 5 mg, was conducted in Harare Maternity Hospital. A total of 152 women were admitted for induction of labor with a term singleton, pregnancy and cephalic presentation were recruited. The main outcome was duration of induction. RESULTS: There were no differences in the characteristics of women in the two groups at recruitment. In the misoprostol group there was a significantly reduced need for augmentation of labor with oxytocin (OR=0.36; 95% C.I. 0.17-0.73) and delivery by cesarean section for failure to progress (OR=0.11; 95% C.I. 0.00-0.88). The risk for duration of induction to vaginal delivery exceeding 12, 18 or 24 h was reduced by 18%, 38% and 68%, respectively, but only the risk for duration >24 h was significantly reduced (OR=0.32; 95%C.I. 0.11-0.91). The mean duration of induction was shorter in the misoprostol group, 15.2 vs. 23.6 h (P=0.02). There were no differences in fetal outcome. CONCLUSION: Misoprostol 50 microg was associated with less use of oxytocin in labor, a shorter induction to delivery interval and fewer cesarean sections for failure to progress when compared with extra-amniotic PGF2alpha gel.

Usefulness of risk scoring at booking for antenatal care in predicting adverse pregnancy outcome in a rural African setting.

Antenatal care (ANC) attempts to screen and provide surveillance and treatment to individuals according to the level of need. We assessed the value of antenatal risk allocation made at the first visit in identifying women who will experience pregnancy complications in a rural area in Zimbabwe. As part of an ANC trial women were allocated into low- and high-risk categories based on medical, demographic and obstetric history. All highrisk women were recommended hospital delivery. This evaluation is based on 5223 women who received traditional care from nurse-midwives in 12 rural health centres, of whom 2890 (55%) were classified as high risk by the traditional risk markers, including 1618 nulliparous women. Complications occurred in 924 (17.7%) women 577 (62.4%) of whom had risk markers identified at booking. Twenty per cent (577/2890) of women classified as high risk developed complications. There was a high recurrence of complications, such as hypertensive disorders, operative delivery and preterm delivery. Nulliparity was a risk for low birth weight, operative delivery and hypertensive disorders, whereas grandmultiparity (> or =6) was a risk for hypertension in pregnancy. Young age (< or =16 years) was)a risk factor for low birth weight and perinatal death. Age above 35 years was not an independent risk factor. The traditional risk allocation system, with a likelihood ratio of 1.16, was not effective in identifying women at risk of pregnancy complications and resulted in too large a risk group for referral.

Iron status and iron deficiency anaemia in adolescents in a Tanzanian suburban area.

OBJECTIVES: To assess the extent and degree of anaemia in adolescents in a Tanzanian suburban area, to estimate the contribution of iron deficiency, using serum (S)-ferritin and soluble transferrin receptor (sTfR) as markers of iron deficiency. MATERIALS: Consecutive primigravidae at booking for antenatal care (n = 76), primary school boys (n = 101) and postmenarchal girls (n = 130) age >or=12 years were investigated. METHODS: Weight and height were measured; venous blood was drawn for haematological analyses, malaria screening, S-ferritin, sTfR, and C-reactive protein. Stool specimens were analysed for intestinal parasites. RESULTS: Anaemia (Hb <105 g/l) was highly prevalent in adolescent primigravidae (75.5%). Adolescent girls were more anaemic (Hb <120 g/l) than boys (14.5 vs. 7.9%). Iron deficiency and hookworm infestation were predominant in both groups of adolescents, however, malaria contributed more to anaemia in the primigravidae. Nearly 40% of the anaemic primigravidae had indication of infection, and S-ferritin was less useful as a marker of iron deficiency in this group. sTfR identified iron deficiency in both pregnant and non-pregnant adolescents.

Anaemia in women of reproductive age in Dar-es-Salaam, Tanzania.

BACKGROUND: Anaemia is among the greatest health problems in reproductive age women in developing countries. OBJECTIVES: To estimate the prevalence of anaemia among non-pregnant parous women, and to investigate the main underlying cause for the anaemia. SETTING: A sub-urban Maternal and Child Health Clinic (MCH) in Dar es Salaam. DESIGN: Cross-sectional. METHODS: Consecutive parous non-pregnant women who had brought their children for vaccination and/or had come for family planning to Mbagala MCH clinic were invited to participate in the study. Obstetric and social history was recorded, and their height and weight were checked. Haemoglobin was measured using HemoCue hemoglobinometer. Anaemic women were further investigated to determine the cause of anaemia by haematological and biochemical tests. RESULTS: Five hundred and four parous non-pregnant women were screened, 49% were anaemic (Hb <12 g/dl) and 1.6% severely anaemic (Hb <7 g/dl). Anaemia was not related to socio-demographic and obstetric history characteristics, but decreased significantly with increasing Body Mass Index (BMI) (p=0.042). The prevalence of anaemia was significantly lower in women using hormonal contraceptives, compared to non-users (36% vs 54%) (p=0.04). Eighty-seven percent of the anaemic women were iron deficient and 8.7% had elevated serum C-reactive protein indicating undiagnosed infections. CONCLUSION: Nutritional deficiencies in women have to be corrected before and between pregnancies and all contacts women have with the health system should be utilised for anaemia control interventions, in addition to long-term community approaches. To improve maternal health calls for a broader agenda and a change of approach in the MCH-clinics.

Increased mortality in diabetes during the first 10 years of the disease. A population-based study (DISS) in Swedish adults 15-34 years old at diagnosis.

OBJECTIVES: To study, prospectively, in young adult patients, the mortality during the first years after the diagnosis of diabetes. DESIGN: The Diabetes Incidence Study in Sweden (DISS) aims to register all incident cases aged 15-34 years. During a 10-year period all deaths were identified by record linkage to the national Cause of Death Registry. SUBJECTS: During the period, 4097 new cases were registered and classified as type 1 diabetes (73%), type 2 (16%), secondary (2%) and unclassified (9%). The median follow-up was 5 years (21 001 person-years). MAIN OUTCOME MEASURES: Calculation of the standardized mortality ratio (SMR) and 95% confidence interval (CI). Evaluation of all deceased by scrutiny of clinical records, death certificates and autopsy protocols. RESULTS: Fifty-eight patients died, corresponding to an SMR of 3.5 (CI=2.7-4.5), which increased from 1.5 at 15-19 years to 4.1 at 30-34 years. SMR was 2.7 in primary diabetes: 2.3 (1.6-3.3) in type 1 and 4.1 (2.6-6.7) in type 2. In secondary diabetes, alcohol-associated pancreatitis a common cause, SMR was 32 (CI=24-45). Evidence of alcohol or drug misuse, mental dysfunction or suicide was found in 40 of all 58 deceased cases. Less often, hypoglycaemia (n=7) or hyperglycaemia-ketoacidosis (n=11) was present at death. Unexplained 'dead in bed' was found once. CONCLUSIONS: In the investigated population-based cohort the early mortality was about threefold increased. Hypoglycaemia and ketoacidosis per se played a relatively small role compared with a heavy impact from social and mental dysfunction, and from careless use of alcohol or drugs.

An incident case-control study of first unprovoked afebrile seizures in children: a population-based study of pre- and perinatal risk factors.

PURPOSE: The aim of this prospective incident community-based study was to assess the influence of pre- and perinatal risk factors in children in whom an unprovoked afebrile epileptic seizure later developed. METHODS: From November 1, 1985, until June 30, 1987, 75 children aged 0-15 years with a first unprovoked afebrile seizure were identified. After exclusion of cases with neonatal seizures (n = 14), two controls per case were selected from the same province in northern Sweden matched by age and sex. Files from maternity wards and pediatric clinics could be traced for 58 cases and 109 controls. These formed the study group. RESULTS: In the univariate analysis, the risk for an unprovoked afebrile seizure was significantly elevated for birth order (OR = 9.3; CI, 2.2-39), vaginal bleeding (OR = 17; 95% CI, 3.5-85), onset of hypertension during pregnancy (OR = 4.8; CI, 1.3-17), cesarean section (OR = 18; 95% CI, 3.7-88), short or long gestational age (OR = 6.7; 95% CI, 2.0-22), and an Apgar score < or =6 at any time (OR = 3.8; 95% CI, 1.2-12). None of these six factors was present in 48.3% of the cases and 89% in the controls. A combination of two or more risk factors found to be significant in the univariate analysis showed a pronounced increased risk for seizures (OR = 19; 95% CI, 5.6-65). In the multivariate analysis, the following characteristics remained statistically significant: vaginal bleeding, gestational age, and Cesarean section. Furthermore, smoking also was identified as a risk factor in the multivariate analysis (OR = 3.4; 95% CI, 1.1-10). CONCLUSIONS: Both pre- and perinatal factors may be associated with later development of epileptic seizures in children. However, in many of the cases, no such factors were identified.

Service screening with mammography of women aged 50-69 years in Sweden: effects on mortality from breast cancer.

OBJECTIVES: To estimate the effect of the population based service screening programme in Sweden on mortality from breast cancer among women aged 50-69. SETTING; In 1986, population based service screening with mammography started in Sweden, and by 1997 screening had been introduced in all counties. Half of the counties invite women from 40 years of age whereas women 50 and older are invited in the other counties. The upper age limit was either 69 or 74. Women in the age group 50-69 years are thus invited to screening in all counties. METHODS: The counties which started with mammographic screening in 1986-87 constituted the study group and were compared with the counties which started in 1993 or later. In 1987 the mean number of women aged 50-69 was 161,986 and 98,608 in the study and control groups, respectively. Refined excess mortality (smoothed with the Lowess method) from breast cancer and refined cause specific mortality from breast cancer were used as effect measures. To adjust for geographical differences in mortality from breast cancer a reference period was used. Allowance was made for two potential biases: (a) inclusion bias implying the inclusion of cases diagnosed before invitation to screening in the first screening round, and (b) lead time bias. RESULTS: After a mean follow up time of 10.6 years since the start of screening and a mean individual follow up time of 8.4 years, a non-significant reduction in refined excess mortality for breast cancer was estimated as relative risk (RR) 0.84 (95% confidence interval (95% CI) 0.67 to 1.05). After adjustment for inclusion and lead time biases the RR was 0.80 (20% reduction). Only 27% of the deaths from breast cancer in the total mortality for women aged 50-79 at death consisted of women aged 50-69 at diagnosis who were diagnosed after the start of screening. This figure has important implications for judgement of the impact of screening on age specific national breast cancer mortalities. CONCLUSIONS: A non-significant reduction in mortality from breast cancer was found in counties performing service screening with mammography in Sweden. Adjustment for possible biases changed the result towards a larger effect of screening. The results do not contradict the effects found in the Swedish randomised mammography trials.

Family characteristics and life events before the onset of autoimmune type 1 diabetes in young adults: a nationwide study.

OBJECTIVE: To elucidate whether family characteristics and stressful life events were associated with onset of autoimmune type 1 diabetes in young adults. RESEARCH DESIGN AND METHODS: This investigation was based on a nationwide study (Diabetes Incidence Study in Sweden) of newly diagnosed patients aged 15-34 years. Patients clinically classified as type 1 diabetic with antibodies to islet cells and/or to GAD65 were compared with age- and sex-matched control subjects via questionnaire. The questionnaire covered diabetes heredity, social environment, educational level, and life events experienced during the 12 months before diagnosis. RESULTS: The rate of response was 82% for the diabetic patients and 65% for the control subjects. Questionnaires from 349 diabetic patients and 979 control subjects were considered. Diabetes in relatives was more frequent in the patients (odds ratio [OR]2.6) who were born in Sweden and whose mothers were of Swedish origin. No major stress factors were detected in the diabetic patients; however, in comparison with the control subjects, the diabetic patients had experienced fewer conflicts with their parents and had less often broken contacts with friends. CONCLUSIONS: Young adults with recent-onset type 1 diabetes were more exposed to heredity for diabetes, but no major prediabetic stress factors were detected. Our study does not directly support the concept that psychosocial stressful life events are involved in the development of autoimmune type 1 diabetes in young adults.
