Since medieval times, an association between religiosity and anorexia nervosa has been suggested, but few systematic studies exist. This study examines in a nationwide setting whether personal or family religiosity is associated with lifetime anorexia nervosa among women in adolescence and early adulthood. Women (N = 2,825) from the 1975 to 1979 birth cohorts of Finnish twins were screened for lifetime DSM-5 anorexia nervosa (N = 92). Parental religiosity was assessed by self-report when the women were aged 16 years. The women self-reported their religiosity at ages 16 and 22 to 27 years. Parental religiosity did not increase the risk of lifetime anorexia nervosa, and neither did religiosity of the women themselves in adolescence. In early adulthood, a J-shaped curve was compatible with the data, indicating increased risk both at low and high levels of religiosity, but this result was statistically non-significant. Religiosity was weakly negatively correlated with body dissatisfaction. There was some suggestive evidence for socioregional variation in the association of religiosity with lifetime anorexia nervosa. In this first population study to directly address religiosity and anorexia nervosa, no evidence was found for a significant association of religiosity with anorexia nervosa either at the personal or family level. Some regional differences are possible. A modest protective association of religiosity with body dissatisfaction is also possible. Despite compelling case descriptions of "holy anorexia," religiosity does not appear to be a central factor in the development of anorexia nervosa in Finland, a highly secularized Christian country.

Objective To examine the occurrence, course, and clinical picture of the DSM-5 residual categories ‘Other Specified Feeding or Eating Disorder’ (OSFED) and ‘Unspecified Feeding or Eating Disorder’ (UFED), to describe potential subtypes, and to evaluate whether the subdivision of the residual category appears meaningful. Method We screened women from the 1975–79 birth cohorts of Finnish twins (N = 2825) for lifetime eating disorders using questionnaires and the SCID interview. This analysis characterizes women who reported clinically significant eating disorder symptoms but did not fulfill diagnostic criteria for DSM-5 anorexia nervosa (AN), bulimia nervosa (BN), or binge eating disorder (BED). Results Thirty-eight women (21% of those with an eating disorder) fell in the residual OSFED/UFED category. A third of them (N = 14) fulfilled OSFED criteria, whereas two thirds (N = 24) fell in the UFED category. The lifetime prevalence of OSFED/UFED was 1.5% (95% CI 1.1–2.0%), less than half of the prevalence of DSM-IV eating disorder not otherwise specified (EDNOS). The mean age of onset of OSFED/UFED was 18 years, median duration of symptoms was two years, and the 5-year probability of recovery was 60%. Over a third of women with OSFED/UFED suffered from comorbid psychiatric disorders. Both residual categories were clinically heterogeneous and included atypical forms of AN, BN, and BED. Conclusions Applying the DSM-5 criteria in a community sample of young women more than halved the occurrence of residual eating disorder diagnoses, but resulted in two instead of one clinically heterogeneous residual categories. Nevertheless, residual eating disorders were associated with considerable clinical severity. © 2016 Wiley Periodicals, Inc. (Int J Eat Disord 2016; 49:1010–1017)

Objective Eating disorders and alcohol use disorders often co-occur, but few prospective studies have examined their relationship. Using a large population-based twin sample, we investigated how the drinking behaviors of women with lifetime eating disorders unfold from adolescence to adulthood. Method We identified 182 women with a lifetime eating disorder assessed at mean age 24, including 92 women with DSM-5 anorexia nervosa and 58 women with DSM-5 bulimia nervosa, from the 1975–1979 birth cohorts of Finnish twins (N = 2,825 women). Frequency of drinking and intoxicating were assessed at ages 16, 24, and 34. Drinking problems were assessed at ages 24 and 34 by the Malmo-modified Michigan Alcohol Screening Test (Mm-Mast) and the Rutgers Alcohol Problem Index (RAPI). Results At age 16, proportionately more women with eating disorders reported being severely intoxicated when they last drank (25% vs.16%, P = 0.001), and at both surveys in adulthood, they reported more frequent intoxication and more alcohol-related problems than their unaffected peers. Those who had recovered from their eating disorder at age 24 still reported more alcohol-related problems in their 30s than did other women. The age of drinking onset, number of monthly drinking days, or frequency of intoxication in adolescence did not differ between women with lifetime eating disorders and unaffected women. Discussion Women with eating disorders scored higher than their unaffected peers on scales measuring alcohol dependence, alcohol-related problems, and intoxication. These differences persisted from mid-adolescence into young adulthood. Women with eating disorders should be assessed routinely for drinking behaviors. © 2016 Wiley Periodicals, Inc.

ObjectiveFew studies have assessed outcomes of anorexia nervosa (AN) outside clinical settings. We aimed to assess mortality, recovery, and socio-demographic outcomes of AN in a community sample. MethodWomen in the nationwide FinnTwin16 cohort (born 1975-1979) were followed for 10 years after baseline diagnostic assessment (mean age at follow-up 34 years, N=2188). We compared women with lifetime DSM-IV AN (N=40) with unaffected women from the same cohort. ResultsNone of the women with AN had died and 88% were weight-recovered (BMI18.5 kg/m(2)), but their mean BMI (22.0 kg/m(2)) was lower than among unaffected women (24.0 kg/m(2), p=0.008). University degrees (38 vs. 29%, p=0.26), sickness absence during the past year (median 5 vs. 3 days, p=0.21), or unemployment or disability pension (5 vs. 4%, p=0.62) did not significantly differ between AN probands and their unaffected peers. More women with AN were still studying (15 vs. 4%, p=0.003), and half of them had children, as compared to 66% of unaffected women (p=0.05). DiscussionThe long-term prognosis of AN in the community appears promising. Weight-restoration is common and socio-demographic outcomes are generally favorable. However, women with a history of AN may be less likely to have children. (c) 2015 Wiley Periodicals, Inc. (Int J Eat Disord 2015; 48:851-859).

Objective: To assess the population prevalence and incidence of binge eating disorder (BED) among young women. Method: In a nationwide longitudinal study of Finnish twins born 1975-1979, the women participated in five surveys from age 16 until their mid-thirties. At Wave 4 (mean age 24 years), the women (N = 2,825) underwent a 2-stage screening for eating disorders. We assessed the lifetime prevalence, incidence, and clinical characteristics of DSM-5 BED. Results: We detected 16 women who met DSM-5 criteria for BED, yielding a lifetime prevalence of 0.7% (95% confidence interval [CI] 0.4-1.2%). The incidence of BED among women between 10 and 24 years of age was 35 (95% CI 20-60) per 100,000 person-years. The mean age of onset of BED was 19 years (range 13-27 years). Of the cases, 13/16 (81%) were currently ill. Duration of illness at the time of assessment ranged from less than a year to 13 years (median 6 years). Of women with BED, only two had a history of other eating disorders, but six had lifetime major depressive disorder. Two-thirds of the women with BED belonged to the highest weight quartile at age 16, and their mean BMI at age 22-27 year was 26.2 kg/m(2) (range 22.1-32.5 kg/m(2)). Discussion: Incident BED as defined by DSM-5 was relatively rare among younger women and was often preceded by relative overweight. BED often occurred without a history of other eating disorders, but comorbidity with major depressive disorder was common. (C) 2015 Wiley Periodicals, Inc.

Objective The association between eating disorders and migraine remains unclear. Method We identified women with lifetime diagnoses of anorexia nervosa (AN) (N = 55) and bulimia nervosa (BN) (N = 60) and their co-twins from the FinnTwin16 cohort born in 1975–1979 (N = 2,825 women). Eating disorder and major depressive disorder (MDD) diagnoses were obtained from clinical interviews and data on migraine by self-report questionnaire. The women with eating disorders were compared with their unaffected co-twins and with unrelated women from the same birth cohorts. Results The prevalence of migraine was 12% in the general female population, but 22% for both AN and BN (odds ratio 2.0, p = .04). The prevalence of MDD was high in women with an eating disorder (42%). MDD was strongly associated with migraine (odds ratio 3.0, p
