- OBJECTIVES: There is a concern that persistent organohalogen toxicants, such as polychlorinated biphenyls (PCBs), might display endocrine-disrupting effects in exposed populations. In this study the correlations between PCBs and thyrotropin (TSH) and thyroid hormone concentrations in plasma were assessed in adult women.METHODS: The study group consisted of 182 fishermen's wives from the Swedish east coast, with a median age of 42 years (range 23-62) and a median current consumption of contaminated fatty fish from the Baltic Sea of two meals per month (range 0-12). TSH, free (FT3) and total (TT3) triiodothyronine and free (FT4) and total (TT4) thyroxin in plasma were analyzed by immunofluorometric assays, and 2,2',4,4',5,5'-hexachlorobiphenyl (CB-153) in plasma was analyzed by gas chromatography with electron capture detection. Twenty other PCB and two hydroxy-PCB congeners were analyzed in subgroups of the women. Plasma lipid analyses were performed with enzymatic techniques.RESULTS: The CB-153 concentration in plasma (range 16-776 ng/g lipid) was negatively correlated with the TT3 concentrations (range 1.0-3.0 nmol/l, rs = -0.29, P < 0.001). This association remained after age adjustment.CONCLUSIONS: The present study gives some support for the notion that dietary exposure to persistent organochlorine compounds (POCs) might weakly affect peripheral thyroid hormone concentrations in adult women.

- OBJECTIVES: The purpose of the present study was to assess the effect, on miscarriages and stillbirths, of persistent organochlorine compounds (POC) through dietary intake of fatty fish from the Baltic Sea. METHODS: Information on miscarriages and stillbirths was collected retrospectively by a self-administered questionnaire in a cohort of fishermen's wives from the Swedish east coast (by the Baltic Sea) and in a referent cohort of west coast fishermen's wives. Current fish consumption was used as a proxy for exposure within the east coast cohort. RESULTS: No increase in miscarriages or stillbirths was found in the east coast cohort compared with the west coast group, in fact a decrease in early miscarriages was found (OR 0.48 [95% CI 0.26-0.92]). Moreover, no increase in risk was found for current high consumers of fatty fish within the east coast cohort. CONCLUSIONS: The present data provided no evidence that dietary POC exposure increases miscarriage and stillbirth rates.

- OBJECTIVES: The purpose of this study was to assess the effect of persistent organochlorine compounds through the dietary intake of fatty fish from the Baltic Sea on human fertility. METHODS: Information on time to pregnancy, subfertility, and infertility was collected retrospectively by self-administered questionnaires in 2 cohorts of fishermen's wives from the Swedish east (by the Baltic Sea) and west coasts. In addition to cohort affiliation, current fish consumption and growing up in a fishing village were used as proxies for exposure within the eastcoast cohort. RESULTS: A decreased success (ie, pregnancy) rate and a tendency towards increased subfertility was found for heavy smokers (> or =10 cigarettes/day) in the eastcoast cohort as compared with the westcoast cohort [success rate ratio 0.66, 95% confidence interval (95% CI) 0.49-.89; subfertility odds ratio 1.64, 95% CI 0.91-2.91). However, internal analyses within the eastcoast cohort did not show that growing up in a fishing village or high current fish consumption decreased the success rate. Eastcoast cohort affiliation showed an increased risk for infertility (odds ratio 2.49, 95% CI 1.05-5.92). CONCLUSIONS: The present data give some support for a negative association between exposure to persistent organochlorine compounds and fertility among heavy smokers. However, when the proxy exposure measures are also considered, the findings are not consistent. Better individual exposure assessments should be used before more firm conclusions are drawn.

- OBJECTIVE: To explore the risk factors that have been suggested to be associated with the development of SLE. METHODS: A case-control study was performed and a questionnaire was developed to obtain the data. Consecutive female incident cases diagnosed between 1981 and 1999 in a defined geographical area in southern Sweden were included. Controls, matched for calendar year of birth, were selected randomly from the same area. In total, 85 cases and 205 controls agreed to participate. The questionnaire included questions about formal education, body weight and height, medical history, family history of autoimmune diseases, exposure to ultraviolet radiation, animals, hair-colouring dyes, alfalfa (lucerne) sprouts, smoking and alcohol habits, history of physical traumata, blood transfusion, silicone breast implants, exogenous oestrogens, other medication, and significant negative life events. RESULTS: Using a multivariate model, a history of hypertension [odds ratio (OR)=3.7, 95% confidence interval (CI) 1.4-9.8], drug allergy (OR=3.6, 95% CI 1.4-9.5), a type I/II sun-reactive skin type (OR=2.3, 95% CI 1.1-4.8) and a family history of SLE (OR=6.8, 95% CI 1.4-32) were all significantly associated with an increased risk of developing SLE, whereas consumption of alcohol was inversely associated with the risk of SLE (use of alcohol very seldom, OR=1.0; 1-150 g/month, OR=0.4, 95% CI 0.2-1.0; >150 g/month, OR=0.2, 95% CI 0.1-0.5). A suggested association with increased SLE risk was seen for smoking (OR=1.8, 95% CI 0.9-3.6) and blood transfusions (OR=2.3, 95% CI 0.9-5.8). Neither exposure to exogenous oestrogen nor exposure to hair-colouring dyes was associated with SLE. CONCLUSIONS: Risk factors of both exogenous and endogenous origin were identified in this population-based series of SLE patients.
