Dietary intake, leisure time activities and obesity among adolescents in Western Sweden: a cross-sectional study.

Background: Overweight and obesity among adolescents are increasing worldwide. Risk factors include dietary intake characteristics and high levels of physical inactivity. In Sweden, few large comprehensive population-based surveys of dietary intake and lifestyle among adolescents have been carried out.

Homocysteine levels and lacunar brain infarcts in elderly women: the prospective population study of women in Gothenburg.

Objectives: To examine whether total serum homocysteine (tHcy) in a population-based sample of middle-aged women is an independent risk factor for presence of lacunar infarcts (LIs) 24 years later.

Design: Prospective population study, follow-up time 24 years.

Setting: Gothenburg, an urban area in western Sweden.

Estimation of the prevalence of primary Sjögren's syndrome in two age-different community-based populations using two sets of classification criteria: the Hordaland Health Study.

Objective: To estimate the point prevalence of primary Sjögren's syndrome (pSS) in two populations, aged 40-44 and 71-74 years, using two sets of classification criteria.

Methods: The participating individuals were recruited from the Hordaland Health Study (HUSK) conducted during 1997-99. A total of 18 592 individuals born 1953-57 and 3346 individuals born 1925-27 were sent a questionnaire covering various health-related questions, including four questions about sicca symptoms.

Reliability and sensitivity of diagnostic tests for primary Sjögren's syndrome.

Objective: To investigate whether diagnostic tests for primary Sjögren's syndrome (pSS) are reproducible when repeated after one year (reliability). To evaluate whether the sensitivity of the diagnostic tests increases with repeated testing.

Methods: A structured interview investigating the subjective sensation of dry eyes and dry mouth, and the diagnostic tests Schirmer I, unstimulated whole saliva collection (UWSC), serological tests for antinuclear antibodies (ANA), for anti-Ro/SSA and anti-La/SSB antibodies as well as Waaler's test for rheumatoid factor, were performed twice with a one year interval in 66 patients with pSS.

Methylmercury and inorganic mercury in serum--correlation to fish consumption and dental amalgam in a cohort of women born in 1922.

Methylmercury in serum (S-MeHg) was assessed from serum concentrations of total (S-TotHg) and inorganic mercury (S-InoHg), determined by cold vapor-atomic absorption spectrometry. The samples were collected from 135 women on two occasions, in 1968-1969 and 1980-1981. In a subgroup of 29 women, an association was found between S-MeHg and the amount of fish consumed in 1968-1969 (r = 0.
