- Second primary cancers (SPCs) account for an increasing proportion of all cancer diagnoses and family history of cancer may be a risk factor for SPCs. Using the Swedish Family-Cancer Database on non-Hodgkin lymphoma (NHL), we assessed the influence of family history on risk of SPCs and of SPCs on survival. NHL patients were identified from the years 1958 to 2015 and generalized Poisson models were used to calculate relative risks (RRs) for SPCs and familial SPCs. Among 14,393 NHL patients, a total of 1,866 (13.0%) were diagnosed with SPC. Familial risk of nine particular cancers was associated with risks of these cancers as SPCs, with twofold to fivefold increase in RRs. At the end of a 25-year follow-up period, the survival probability for persons with SPC was only 20% of that for patients without SPC; the hazard ratio for SPC was 1.59 (95% CI: 1.46–1.72). Survival could be predicted by the prognostic groups based on first cancers and HRs increase systematically with worse prognosis yielding a trend of p = 4.6 × 10 −5 . SPCs had deleterious consequences for survival in NHL patients. Family history was associated with increasing numbers of SPCs. Prevention of SPCs and their early detection is an important target in the overall strategy to improve survival in NHL patients. Counseling for avoidance of risk factors and targeted screening based on family history are feasible steps in risk reduction.

Tidskriftsartikel (refereegranskat)abstract
- Second primary cancers (SPCs) are becoming a common cancer entity, which may interfere with survival in relatively benign first primary cancers. We examined the hypothesis that immune dysfunction may contribute to SPCs by assessing SPCs associated with known immune responsive skin cancers, invasive and in situ squamous cell carcinoma, Kaposi sarcoma, and Merkel cell carcinoma. Cancers were identified from the Swedish Cancer Registry from the year 1958 to 2015. Standardized relative risks were calculated bidirectionally for any SPC after skin cancer and for skin cancer as SPC. Over 80,000 first primary cancers were identified for each invasive and in situ squamous cell carcinoma of the skin. Bidirectional increased risks were observed for 26 cancers associated with invasive skin cancer; the Spearman rank correlation was 0.72 (P = 4.6 × 10–5). The highest bidirectional relative risks were for invasive and in situ skin cancer as SPCs (14.59 and 16.71, respectively). Remarkably high risks for second in situ squamous cell carcinoma of the skin were found after Kaposi sarcoma (685.68) and Merkel cell carcinoma (117.23). The high systematic bidirectional risks between immune responsive skin cancers and most other cancers suggest that immune suppression is a key mechanism contributing to an increased risk of SPCs.

Drinking cultures and socioeconomic risk factors for alcohol and drug use disorders among first- and second-generation immigrants : A longitudinal analysis of Swedish population data
- 2021
-
Ingår i: Drug and Alcohol Dependence. - : Elsevier BV. - 0376-8716. ; 226
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Few longitudinal studies investigate predictors of substance use incidence among immigrants. The current study describes substance use disorders in immigrants to Sweden, focusing on drinking culture in the country of origin and socioeconomic status (SES), and how these intersect with generational status to influence risk. Methods: Using pseudonymized Swedish population registry data, we track onset of alcohol use disorder and drug use disorder in a longitudinal study of 815,778 first-generation immigrants and 674,757 second-generation immigrants from 64 countries over a 6-year period. Cox regression analysis estimated risks of alcohol and drug use disorders in second-generation immigrants compared to first-generation, and moderation analyses assessed interactions of generational status with country-of-origin per capita alcohol consumption and SES. Results: Immigrants and second-generation immigrants originating from countries with high levels of alcohol consumption had higher risks for alcohol and drug use disorders. Immigrants with high SES had lower risks for alcohol and drug use disorders. The interaction between generational status and country-of-origin alcohol consumption was significant for drug use disorder (not for alcohol use disorder), with drug use disorder risk for second-generation immigrants being highest for those from countries with the lowest level of country-of-origin per capita alcohol consumption. The interaction between generational status and SES was significant for alcohol use disorder, with low-SES second-generation immigrants showing markedly higher risk than first-generation immigrants with comparable SES. Conclusions: Among immigrants in Sweden, second-generation immigrants are at increased risk of developing alcohol and drug use disorders, particularly if they have lower SES. Policy and community attention to these high-risk subgroups in immigrant communities is warranted.

Adult outcomes of preterm birth
- 2016
-
Ingår i: Preventive Medicine. - : Elsevier BV. - 0091-7435. ; 91, s. 400-401
-
Tidskriftsartikel (refereegranskat)abstract
- Because of remarkable advances in the treatment of preterm birth, physicians increasingly encounter adult patients who were born preterm. However, research now shows that improved early survival may come at the expense of future health risks, including increased respiratory, cardiovascular, and kidney disease, diabetes and metabolic syndrome, and neuropsychiatric disorders. Unfortunately, this knowledge is not yet reflected in patient care. The NIH recently convened a conference of multidisciplinary international experts who called for better awareness among physicians regarding adult outcomes of preterm birth, which is critically needed for enabling them to identify and provide better care for these patients across the life course. This Letter aims to promote awareness of this issue among physicians in order to inform long-term patient care and policy. The continued high (~ 10%) prevalence of preterm birth and unprecedented numbers who are surviving into adulthood mean that the long-term health effects will have a growing clinical and public health impact in the future.

Adverse Pregnancy Outcomes and Long-Term Mortality in Women
-
Ingår i: JAMA Internal Medicine. - 2168-6114.
-
Tidskriftsartikel (refereegranskat)abstract
- Importance: Women with adverse pregnancy outcomes, such as preterm delivery or preeclampsia, have higher future risks of cardiometabolic disorders; however, little is known about their long-term mortality risks. A better understanding of such risks is needed to facilitate early identification of high-risk women and preventive actions. Objective: To determine long-term mortality risks associated with 5 major adverse pregnancy outcomes in a large population-based cohort of women. Design, Setting, and Participants: This national cohort study in Sweden used the Swedish Medical Birth Register, containing prenatal and birth information for nearly all deliveries in Sweden since 1973, to identify women who had a singleton delivery during 1973 to 2015. All 2195667 such women with information for pregnancy duration and infant birth weight were included in the study. Data were analyzed from March to September 2023. Exposure: Adverse pregnancy outcomes (preterm delivery, small for gestational age, preeclampsia, other hypertensive disorders, and gestational diabetes), identified from nationwide birth records. Main Outcome and Measures: All-cause and cause-specific mortality through December 31, 2018. Cox regression was used to compute hazard ratios (HRs) for mortality associated with specific adverse pregnancy outcomes, adjusted for other maternal factors. Cosibling analyses assessed for confounding by shared familial (genetic or environmental) factors. Results: In 56 million person-years of follow-up to a median (IQR) age of 52 (42-61) years, 88055 women (4%) died (median [IQR] age at death, 59 [50-67] years). All 5 adverse pregnancy outcomes were independently associated with increased mortality. Across the entire follow-up (≤46 years after delivery), adjusted HRs for all-cause mortality associated with specific adverse pregnancy outcomes were as follows: gestational diabetes, 1.52 (95% CI, 1.46-1.58); preterm delivery, 1.41 (95% CI, 1.37-1.44); small for gestational age, 1.30 (95% CI, 1.28-1.32); other hypertensive disorders, 1.27 (95% CI, 1.19-1.37); and preeclampsia, 1.13 (95% CI, 1.10-1.16). All HRs remained significantly elevated even 30 to 46 years after delivery. These effect sizes were only partially (0%-45%) reduced after controlling for shared familial factors in cosibling analyses. Women who experienced multiple adverse pregnancy outcomes had further increases in risk. Several major causes of death were identified, including cardiovascular and respiratory disorders and diabetes. Conclusions and Relevance: In this large national cohort study, women who experienced any of 5 major adverse pregnancy outcomes had increased mortality risks that remained elevated more than 40 years later. Women with adverse pregnancy outcomes need early preventive evaluation and long-term follow-up for detection and treatment of chronic disorders associated with premature mortality.

- Background: Women with adverse pregnancy outcomes may have higher subsequent risk of chronic kidney disease, but the long-term independent risks and potential causality are unclear. Objective: This study aimed to determine long-term risks of chronic kidney disease associated with 5 major adverse pregnancy outcomes in a large population-based cohort, and to assess for familial confounding using co-sibling analyses. Study Design: A national cohort study was conducted of all 2,201,279 women with a singleton delivery in Sweden from 1973 to 2015, followed up for chronic kidney disease identified from nationwide diagnoses through 2018. Cox regression was used to compute hazard ratios for chronic kidney disease associated with preterm delivery, small for gestational age, preeclampsia, other hypertensive disorders, and gestational diabetes, adjusting for other adverse pregnancy outcomes and maternal factors. Co-sibling analyses assessed for potential confounding by shared familial (genetic or environmental) factors. Results: In 56 million person-years of follow-up, 11,572 (0.5%) women were diagnosed with chronic kidney disease (median age, 61 years). All 5 adverse pregnancy outcomes were independently associated with increased chronic kidney disease risk. Within 10 years following delivery, adjusted hazard ratios associated with specific adverse pregnancy outcomes were: 7.12 for other hypertensive disorders (95% confidence interval, 5.88–8.62), 4.38 for preeclampsia (3.72–5.16), 3.50 for preterm delivery (2.95–4.15), 3.15 for gestational diabetes (2.53–3.92), and 1.22 for small for gestational age (1.02–1.44). All hazard ratios remained significantly elevated even 30 to 46 years after delivery (gestational diabetes, 3.32 [95% confidence interval, 2.96–3.72]; other hypertensive disorders, 2.44 [1.91–3.11]; preeclampsia, 2.03 [1.90–2.16]; preterm delivery, 1.56 [1.44–1.68]; and small for gestational age, 1.24 [1.16–1.31]). These findings were only partially (0%–45%) explained by shared familial factors. Women with multiple adverse pregnancy outcomes had further increases in risk. Conclusion: In this large national cohort, women who experienced any of 5 major adverse pregnancy outcomes had increased risk for chronic kidney disease up to 46 years later. Women with adverse pregnancy outcomes need early preventive actions and long-term monitoring to reduce risk of chronic kidney disease.

- Objective: To examine the associations between five major adverse pregnancy outcomes and long term risks of ischemic heart disease in mothers. Design: National cohort study. Setting: Sweden. Participants: All 2 195 266 women with a first singleton delivery in Sweden during 1973-2015. Main outcome measures: The main outcome measure was incidence of ischemic heart disease from delivery to 2018, identified from nationwide inpatient and outpatient diagnoses. Cox regression was used to calculate hazard ratios for ischemic heart disease associated with preterm delivery, small for gestational age, pre-eclampsia, other hypertensive disorders of pregnancy, and gestational diabetes, adjusting for other adverse pregnancy outcomes and maternal factors. Co-sibling analyses assessed for confounding by shared familial (genetic and environmental) factors. Results: During 53.6 million person years of follow-up, ischemic heart disease was diagnosed in 83 881 (3.8%) women. All five adverse pregnancy outcomes were independently associated with increased risk of ischemic heart disease. In the 10 years after delivery, adjusted hazard ratios for ischemic heart disease associated with specific adverse pregnancy outcomes were 2.09 (95% confidence interval 1.77 to 2.46) for other hypertensive disorders of pregnancy, 1.72 (1.55 to 1.90) for preterm delivery, 1.54 (1.37 to 1.72) for pre-eclampsia, 1.30 (1.09 to 1.56) for gestational diabetes, and 1.10 (1.00 to 1.21) for small for gestational age. The hazard ratios remained significantly increased even 30-46 years after delivery: 1.47 (1.30 to 1.66) for other hypertensive disorders of pregnancy, 1.40 (1.29 to 1.51) for gestational diabetes, 1.32 (1.28 to 1.36) for pre-eclampsia, 1.23 (1.19 to 1.27) for preterm delivery, and 1.16 (1.13 to 1.19) for small for gestational age. These findings were only partially (<45%) explained by shared familial (genetic or environmental) factors. Women who experienced multiple adverse pregnancy outcomes showed further increases in risk (eg, <10 years after delivery, adjusted hazard ratios associated with 1, 2, or ≥3 adverse pregnancy outcomes were 1.29 (1.19 to 1.39), 1.80 (1.59 to 2.03), and 2.26 (1.89 to 2.70), respectively)). Conclusions: In this large national cohort, women who experienced any of five major adverse pregnancy outcomes showed an increased risk for ischemic heart disease up to 46 years after delivery. Women with adverse pregnancy outcomes should be considered for early preventive evaluation and long term risk reduction to help prevent the development of ischemic heart disease.

- Objective Low physical fitness and obesity have been associated with higher risk of developing heart failure (HF), but their interactive effects are unknown. Elucidation of interactions among these common modifiable factors may help facilitate more effective primary prevention. Methods We conducted a national cohort study to examine the interactive effects of aerobic fitness, muscular strength and body mass index (BMI) among 1 330 610 military conscripts in Sweden during 1969-1997 (97%-98% of all 18-year-old men) on risk of HF identified from inpatient and outpatient diagnoses through 2012 (maximum age 62 years). Results There were 11 711 men diagnosed with HF in 37.8 million person-years of follow-up. Low aerobic fitness, low muscular strength and obesity were independently associated with higher risk of HF, after adjusting for each other, socioeconomic factors, other chronic diseases and family history of HF. The combination of low aerobic fitness and low muscular strength (lowest vs highest tertiles) was associated with a 1.7-fold risk of HF (95% CI 1.6 to 1.9; p<0.001; incidence rates per 100 000 person-years, 43.2 vs 10.8). These factors had positive additive and multiplicative interactions (p<0.001) and were associated with increased risk of HF even among men with normal BMI. Conclusions Low aerobic fitness, low muscular strength and obesity at the age of 18 years were independently associated with higher risk of HF in adulthood, with interactive effects between aerobic fitness and muscular strength. These findings suggest that early-life interventions may help reduce the long-term risk of HF and should include both aerobic fitness and muscular strength, even among persons with normal BMI.

- Importance: Preterm birth has been associated with increased risk of heart failure (HF) early in life, but its association with new-onset HF in adulthood appears to be unknown. Objective: To determine whether preterm birth is associated with increased risk of HF from childhood into mid-adulthood in a large population-based cohort. Design, Setting, and Participants: This national cohort study was conducted in Sweden with data from 1973 through 2015. All singleton live births in Sweden during 1973 through 2014 were included. Exposures: Gestational age at birth, identified from nationwide birth records. Main Outcomes and Measures: Heart failure, as identified from inpatient and outpatient diagnoses through 2015. Cox regression was used to determine hazard ratios (HRs) for HF associated with gestational age at birth while adjusting for other perinatal and maternal factors. Cosibling analyses assessed for potential confounding by unmeasured shared familial (genetic and/or environmental) factors. Results: A total of 4193069 individuals were included (maximum age, 43 years; median age, 22.5 years). In 85.0 million person-years of follow-up, 4158 persons (0.1%) were identified as having HF (median [interquartile range] age, 15.4 [28.0] years at diagnosis). Preterm birth (gestational age <37 weeks) was associated with increased risk of HF at ages younger than 1 year (adjusted HR [aHR], 4.49 [95% CI, 3.86-5.22]), 1 to 17 years (aHR, 3.42 [95% CI, 2.75-4.27]), and 18 to 43 years (aHR, 1.42 [95% CI, 1.19-1.71]) compared with full-term birth (gestational age, 39-41 weeks). At ages 18 through 43 years, the HRs further stratified by gestational age were 4.72 (95% CI, 2.11-10.52) for extremely preterm births (22-27 weeks), 1.93 (95% CI, 1.37-2.71) for moderately preterm births (28-33 weeks), 1.24 (95% CI, 1.00-1.54) for late preterm births (34-36 weeks), and 1.09 (95% CI, 0.97-1.24) for early term births (37-38 weeks). The corresponding HF incidence rates (per 100000 person-years) at ages 18 through 43 years were 31.7, 13.8, 8.7, and 7.3, respectively, compared with 6.6 for full-term births. These associations persisted when excluding persons with structural congenital cardiac anomalies. The associations at ages 18 through 43 years (but not <18 years) appeared to be largely explained by shared determinants of preterm birth and HF within families. Preterm birth accounted for a similar number of HF cases among male and female individuals. Conclusions and Relevance: In this large national cohort, preterm birth was associated with increased risk of new-onset HF into adulthood. Survivors of preterm birth may need long-term clinical follow-up into adulthood for risk reduction and monitoring for HF.

Tidskriftsartikel (refereegranskat)abstract
- Importance: Preterm birth has previously been associated with increased risks of hypertension and diabetes, but not ischemic heart disease (IHD), in adulthood. The reasons for this lack of association with IHD despite associations with its risk factors have been elusive, but may be associated with methodologic issues, such as survivor bias, in prior studies. Objective: To determine whether preterm birth is associated with an increased risk of IHD in adulthood in a large population-based cohort. Design, Setting, and Participants: This national, population-based cohort study included all 2141709 persons who were born as singleton live births in Sweden during 1973 to 1994. The data were analyzed in September 2018. Exposures: Gestational age at birth, identified from nationwide birth records in the Swedish Birth Registry. Main Outcomes and Measures: Ischemic heart disease that was identified from nationwide inpatient and outpatient diagnoses through 2015 (maximum age, 43 years). A Cox regression was used to examine gestational age at birth in association with IHD in adulthood while adjusting for other perinatal and maternal factors. Cosibling analyses assessed for potential confounding by unmeasured shared familial factors. Results: Of 2141709 participants, 1041906 (48.6%) were female and there were 1921 persons (0.09%) who received a diagnosis of IHD in 30.9 million person-years of follow-up. Gestational age at birth was inversely associated with IHD risk in adulthood. At ages 30 to 43 years, adjusted hazard ratios for IHD associated with preterm (gestational age <37 weeks) and early-term birth (37-38 weeks) were 1.53 (95% CI, 1.20-1.94) and 1.19 (1.01-1.40), respectively, compared with full-term birth (39-41 weeks). Preterm-born women had lower IHD incidence than preterm-born men (15.16 vs 22.00 per 100000 person-years) but had a higher adjusted hazard ratio (1.93; 95% CI, 1.28-2.90 vs 1.37; 95% CI, 1.01-1.84). These associations did not appear to be explained by shared genetic or environmental factors in families. Conclusions and Relevance: In this large national cohort, preterm and early-term birth were associated with an increased IHD risk in adulthood. Persons born prematurely need early evaluation and preventive actions to reduce the risk of IHD.
