- Human papillomaviruses (HPV) are established as a major cause of cervical carcinoma. However, causality inference is dependent on prospective evidence showing that exposure predicts risk for future disease. Such evidence is available for squamous cell carcinoma, but not for cervical adenocarcinoma. We followed a population-based cohort of 994,120 women who participated in cytological screening in Sweden for a median of 6.7 years. Baseline smears from women who developed adenocarcinoma during follow-up (118 women with in situ disease and 164 with invasive disease) and their individually matched controls (1,434 smears) were analyzed for HPV using PCR. Conditional logistic regression was used to estimate odds ratios (OR) of future adenocarcinoma with 95% confidence intervals (CI). Being positive for HPV 16 in the first cytologically normal smear was associated with increased risks for both future adenocarcinoma in situ (OR: 11.0, 95% CI: 2.6-46.8) and invasive adenocarcinoma (OR: 16.0, 95% CI: 3.8-66.7), compared to being negative for HPV 16. Similarly, an HPV 18 positive smear was associated with increased risks for adenocarcinoma in situ (OR: 26.0, 95% CI: 3.5-192) and invasive adenocarcinoma (OR: 28.0, 95% CI: 3.8-206), compared to an HPV 18 negative smear. Being positive for HPV 16/18 in 2 subsequent smears was associated with an infinite risk of both in situ and invasive adenocarcinoma. In conclusion, infections with HPV 16 and 18 are detectable up to at least 14 years before diagnosis of cervical adenocarcinoma. Our data provide prospective evidence that the association of HPV 16/18 with cervical adenocarcinoma is strong and causal.

- Ethnic minorities/immigrant groups tend to have increased risk for preterm birth. Less is known about this risk in diverse immigrant groups, couples of mixed ethnic-origin and in relation to duration of residence. Data from the Swedish Medical Birth Register on 1,028,303 mothers who gave birth to 1,766,026 singleton live born infants (1982–2002), was linked to the Education and Total Population Registers. Immigrant parents were identified by country of birth. Risk of early preterm, late preterm and postterm birth was analyzed using multinomial logistic regression. Polish, Yugoslavian, Iranian, South Asian, East Asian and Sub-Saharan African parents, Swedish mothers who had children with non-Swedish fathers, and parents from two different immigrant groups had higher risk of early preterm birth [adjusted relative risk (RR) (95 % CI) 1.76 (1.24–2.50), 1.57 (1.31–1.87), 1.67 (1.30–2.14), 1.52 (1.07–2.16), 1.51 (1.08–2.10), 2.03 (1.32–3.12), 1.56 (1.45–1.67), and 1.55 (1.35–1.77) respectively] compared to Swedish-born parents. South Asian, Sub-Saharan African, and East Asian immigrants had a higher risk of late preterm birth compared to Swedish-born parents. North African and Middle Eastern, Somali, and Ethiopian/Eritrean groups had increased risk of postterm birth [adjusted RR 1.31 (1.16–1.47), 2.57 (2.31–2.86), 1.85 (1.67–2.04) respectively]. Adjustment for covariates did not substantially change associations. Immigrant mothers resident <3 years had higher risk for early preterm and postterm birth compared to residents >10 years [adjusted RR 1.46 (1.24–1.71) and 1.16 (1.11–1.23) respectively]. In addition to higher risk of preterm birth in select immigrant groups, some immigrant groups are also at higher risk of postterm birth. Shorter duration of residence is associated with higher risk of non-term deliveries.

- The population of Leningrad suffered from severe starvation, cold and psychological stress during the siege in 1941–1944. We investigated long-term effects of the siege on cardiovascular risk factors and mortality in surviving men and women. 3905 men born 1916–1935 and 1729 women born 1910–1940, resident in St Petersburg (formerly Leningrad) between 1975 and 1982, of whom a third experienced the siege as children, adolescents or young adults,were examined for cardiovascular risk factors in 1975–1977 and 1980–1982 respectively and followed till end 2005. Effects of siege exposure on bloodpressure, lipids, body size, and mortality were studied in multivariate analysis stratified by gender and period of birth, adjusted for age, smoking, alcohol and social characteristics. Women who were 6–8 years old and men who were 9–15 years-old at the peak of starvation had higher systolic blood pressure compared to unexposed subjects born during the same period of birth (fully adjusted difference 8.8, 95% CI:0.1–17.5 mm Hg in women and 2.9, 95% CI: 0.7–5.0 mm Hg in men). Mean height of women who were exposed to siege as children appeared to be greater than that of unexposed women. Higher mortality from ischaemic heart disease and cerebrovascular disease was noted in men exposed at age 6–8 and 9–15, respectively. The experience of severe stress and starvation in childhood and puberty may have long-term effects on systolic blood pressure and circulatory disease in surviving men and women with potential gender differences in the effect of siege experienced at pre-pubertal age.

- OBJECTIVE: Case-fatality rates (CFRs) for myocardial infarction (MI) and ischaemic stroke (IS) have decreased over time due to better prevention, medication and hospital care. It is unclear whether these improvements have been equally distributed according to socioeconomic position (SEP) and sex. The aim of this study is to analyse differences in short-term and long-term CFR for MI and IS by SEP and sex between the periods 1990-1994 to 2005-2009 for the entire Swedish population.DESIGN: Population-based cohort study based on Swedish national registers.METHODS: We used logistic regression and flexible parametric models to estimate short-term CFR (death before reaching the hospital or on the disease event day) and long-term CFR (1 year case-fatality conditional on surviving short-term) across five distinct SEP groups, as well as CFR differences (CFRDs) between SEP groups for both MI and IS from 1990-1994 to 2005-2009.RESULTS: Overall short-term CFR for both MI and IS decreased between study periods. For MI, differences in short-term and long-term CFR between the least and most favourable SEP group were generally stable, except in long-term CFR among women; intermediate SEP groups mostly managed to catch up with the most favourable SEP group. For IS, short-term CFRD generally decreased compared with the most favourable group; but long-term CFRD were mostly stable, except for an increase for older subjects.CONCLUSION: Despite a general decline in CFR for MI and IS across all SEP groups and both sexes as well as some reductions in CFRD, we found persistent and even increasing CFRD among the least advantaged SEP groups, older patients and women. We speculate that targeted prevention rather than treatment strategies have the potential to reduce these inequalities.

Tidskriftsartikel (refereegranskat)abstract
- Background We analyzed temporal trends in the incidence of myocardial infarction and ischemic stroke in Sweden by socioeconomic position and investigated whether social inequalities in incidence of these diseases changed over time.Materials and Methods We studied a cohort of almost three million Swedish residents born between 1932 and 1960 followed from 1987 until 2010. Incident cases of myocardial infarction and ischemic stroke were identified in the Swedish National Inpatient Register and Cause of Death Register. Socioeconomic position was retrieved from the Population and Housing Censuses. Incidence rates of myocardial infarction and ischemic stroke and incidence rate ratios comparing levels of socioeconomic position were estimated using flexible parametric survival models adjusted for calendar year, attained age, sex, and birth country.Results The overall incidences of myocardial infarction and ischemic stroke decreased over time among men, but were stable over time among women. With regard to ischemic stroke incidence, socioeconomic inequality increased over time in the age group 55 to 59: the incidence rate ratios for low manual compared to high non-manual increased from 1.3 (95% CI: 1.2-1.4) in 1997 to 1.5 (1.4-1.7) in 2010 among men, and from 1.4 (1.3-1.6) in 1997 to 2.1 (1.8-2.5) in 2010 among women. The socioeconomic inequality in incidence of myocardial infarction was stable over time for both men and women.Conclusion There was a decrease in myocardial infarction and ischemic stroke incidence over time among men but no significant change for women. Our study highlights existing, and in some cases increasing, social inequalities in the incidence of cardiovascular diseases.

Tidskriftsartikel (refereegranskat)abstract
- Background: Intra-generational social mobility, which describes the mobility within an individual’s own working life, is seldom studied among employees with psychiatric disorders (EPD). There is need of knowledge of the intra-generational mobility patterns, in a broader perspective, among EPD.Aims: To investigate intra-generational social mobility in employed individuals diagnosed with affective disorder, personality disorder, schizophrenia and drug dependence in a national Swedish cohort.Method: We identified a national sample of employed Swedish adults born in 1939–1949 (N = 876, 738), and among them individuals with a first-time hospital admission for affective psychosis, neurosis and personality disorder, alcoholism, drug dependence or schizophrenia in 1964–1980 (N = 18, 998). Employed individuals without hospital admission for such diagnoses were utilised as a comparison group (N = 866, 442). Intra-individual social class changes between 1980 and 1990 among EPD and the comparison group were described through summary statistics and graphs.Results: EPD more often held Low manual occupations at baseline in 1980 than the comparison group (44% vs. 28%), although parental social class was similar. In 1990, 19% of EPD and 4% of the comparison group had lost contact with the labour market. Social stability was less common among EPD (49 %) than in the comparison group (67%). Mobility out of the labour force increased and social stability decreased by number of inpatient admissions. Employees diagnosed with affective psychosis or neurosis and personality disorder fared better in the labour market than employees with schizophrenia.Conclusion: Employees suffering from psychiatric disorder do not maintain their social class or remain in the labour force to the same extent as individuals without those problems, irrespective of their parental class. Our results support the social drift hypothesis that individuals with poor psychiatric health move downward in the social hierarchy.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: This study explored how adult social class and social mobility between parental and own adult social class is related to psychiatric disorder.Material and Methods: In this prospective cohort study, over 1 million employed Swedes born in 1949-1959 were included. Information on parental class (1960) and own mid-life social class (1980 and 1990) was retrieved from the censuses and categorised as High Non-manual, Low Non-manual, High Manual, Low Manual and Self-employed. After identifying adult class, individuals were followed for psychiatric disorder by first admission of schizophrenia, alcoholism and drug dependency, affective psychosis and neurosis or personality disorder (N=24 659) from the Swedish Patient Register. We used Poisson regression analysis to estimate first admission rates of psychiatric disorder per 100 000 person-years and relative risks (RR) by adult social class (treated as a time-varying covariate). The RRs of psychiatric disorder among the Non-manual and Manual classes were also estimated by magnitude of social mobility.Results: The rate of psychiatric disorder was significantly higher among individuals belonging to the Low manual class as compared with the High Non-manual class. Compared to High Non-manual class, the risk for psychiatric disorder ranged from 2.07 (Low Manual class) to 1.38 (Low Non-manual class). Parental class had a minor impact on these estimates. Among the Non-manual and Manual classes, downward mobility was associated with increased risk and upward mobility with decreased risk of psychiatric disorder. In addition, downward mobility was inversely associated with the magnitude of social mobility, independent of parental class.Conclusions: Independently of parental social class, the risk of psychiatric disorder increases with increased downward social mobility and decreases with increased upward mobility.

Long-Term Health Consequences Following the Siege of Leningrad
- 2013

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- We are interested in the long-term health consequences associated with severe starvation and war trauma, and whether certain “age windows” exist when exposure to such events are particularly harmful. The siege of Leningrad (now St. Petersburg) during World War II provided an opportunity to study this. For 872 days, German troops prevented supplies from reaching Leningrad. Simultaneously, there was a food blockade and a steady and merciless bombardment by shells from guns and from the air. The first winter, 1941/42, represents the most severe food shortage, amounting to mass starvation or semi-starvation. Our late colleague, Professor Dimitri Shestov, had suffered the consequences of the Leningrad siege as a boy and believed that it had taken a toll on people beyond its immediate short- and medium-range consequences. He was particularly concerned about its long-term consequences for circulatory disease. A 1973 US-Soviet agreement, the so called Lipid Research Clinics Collaboration, gave him an opportunity to study this. From 1975 to 1982 men and women living in Leningrad (now St. Petersburg) were randomly sampled and invited to examine their health and cardiovascular functioning. Dimitri Shestov added a simple question to this examination: “Were you in Leningrad during the blockade?” A third of the participants were. They had experienced peak starvation (in January 1942) at ages 1-31 (women) or 6-26 (men). The mortality follow-up began immediately after the first clinical examinations in 1975 and continued for three decades, until the end of 2005. Our analyses show that the siege of Leningrad, particularly when experienced in puberty, has had long-term effects on blood pressure both in men and women.We also found a raised IHD and stroke risk among those men. This was partly mediated via blood pressure but not by any other measured biological, behavioral, or social factors. Girls experiencing the siege around puberty suffered an elevated risk of dying from breast cancer later in life. The fact that the effect of siege exposure is modified by the age at exposure is highly interesting from a scientific point of view. It may suggest that a reprogramming of physiological systems can occur at specific age windows in response to starvation and/or war trauma. The team that worked from 1975-2005 to collect clinical information and death certificates for participants in the study included Svetlana Plavinskaya, born in Leningrad during the siege. Dimitri Shestov and Svetlana Plavinskaya died in 2010 and 2011, respectively. We dedicate this chapter to their memory.
