AbstractBackgroundThe postpartum period is well-known risk period for the first onset of autoimmune thyroid disorders (AITDs) as well as first onset of psychiatric disorders. These two disorders are some of the most prevalent medical conditions postpartum, often misdiagnosed and disabling if left untreated. Our study was designed to explore the possible bidirectional association between AITDs and psychiatric disorders during the postpartum period.MethodsA population-based cohort study through linkage of Danish national registers, which comprised 312 779 women who gave birth to their first child during 1997–2010. We conducted Poisson regression analysis to estimate the incidence rate ratio (IRR) of psychiatric disorders among women with first-onset AITDs, the IRR of AITDs among women with first-onset psychiatric disorders as well as the overlap between these disorders using a comorbidity index.ResultsWomen with first-onset AITDs postpartum were more likely to have first-onset psychiatric disorders than women who did not have postpartum AITDs (IRR = 1.88, 95% confidence interval (CI): 1.25–2.81). Women with first-onset postpartum psychiatric disorders had a higher risk of AITDs than women with no psychiatric disorders (IRR = 2.16, 95% CI: 1.45–3.20). The comorbidity index 2 years after delivery was 2.26 (95% CI: 1.61–2.90), indicating a comorbidity between first-onset AITDs and psychiatric disorders.ConclusionsFirst-onset AITDs and psychiatric disorders co-occur in the postpartum period, which has relevance to further studies on the etiologies of these disorders and why childbirth in particular triggers the onset.

The Relationship

Background: The prevalence of obesity has increased threefold among Swedish men during recent decades. Knowledge from Sweden on how obese men manage in working life and become disability pensioners is sparse. The aim of this nationwide and population-based cohort study was to investigate to what extent body mass index (BMI) in young adulthood predicts later disability pension. Method: All Swedish men born 1952—59, who had their weight and height measured at age 18 years in the compulsory military conscription examinations, were followed up longitudinally from 1990 to 2001 with regard to receiving disability pension. Data on own socioeconomic position (1985), education and marital status (1990), parental socioeconomic position (1960), and education (1970) were obtained from censuses. For 366,929 men (81% of the eligible men) the hazard ratio for receiving disability pension was calculated with Cox regression controlling for own education, parental education, childhood and adult socioeconomic position, marital status, morbidity, and type of municipality. Results: Obesity in young adulthood increased the risk for disability pension later in life (1.35, 95% CI 1.19, 1.52) compared with men of normal weight. The relationship between BMI and disability pension was J-shaped with higher risks for underweight (1.14, 95% CI 1.09, 1.20) and obese men. Conclusions: Obese men in Sweden are at higher risk of receiving disability pension. The relationship between BMI and disability pension is J-shaped. An important future task is to estimate the societal costs due to disability pension of obese people.

Abstract Objective To investigate the incidence of violent crime conviction among Swedish military veterans after deployment to Afghanistan versus non-deployed comparators. The main outcome was first conviction of a violent crime, retrieved from the Swedish National Council for Crime Prevention Register until December 31, 2013. Methods This was a cohort study of military veterans identified through personnel registers regarding deployment to Afghanistan between 2002 and 2013 (n = 5894). To each military veteran, up to five non-deployed comparators identified via the Military Service Conscription Register were matched by age, sex, conscription year, cognitive ability, psychological assessment, self-reported mental health, body mass index, antidepressants/anxiolytics prescriptions and self-harm (fully matched comparators; n = 28 895). Multivariable adjustment was made for substance abuse and previous health care visits with psychiatric diagnoses. An additional comparator group matched only for age, sex and conscription year was also used (age-sex-matched comparators; n = 29 410). Results During 21 898 person-years of follow-up (median = 3.6 years) there were 26 events among deployed military veterans compared with 98 in non-deployed fully matched comparators [12 vs 9 per 10 000 person-years, adjusted hazard ratio (aHR) 1.36; 95% confidence interval (CI) 0.88–2.10]. Among non-deployed age-sex-matched comparators there were 170 violent crime convictions (16 per 10 000 person-years; aHR 0.85; 95% CI 0.56–1.29). Factors associated with greater risk of violent crime convictions were younger age, lower scores on cognitive ability tests and psychological assessment, and convictions preceding deployment. Conclusion The violent crime conviction rate after returning from military deployment to Afghanistan was not different compared with non-deployed comparators in individuals without history of violent crime convictions.
