Women with a history of gestational diabetes mellitus present an accumulation of cardiovascular risk factors at age 46-A birth cohort study.

INTRODUCTION: The incidence of gestational diabetes mellitus (GDM) is globally increasing, and it has been associated with later type 2 diabetes, metabolic syndrome (MetS), and cardiovascular disease (CVD). However, long-term population-based studies investigating common CVD risk factors years after pregnancy are lacking. To evaluate the future mortality and morbidity in cardiovascular and metabolic diseases, we conducted a thorough investigation of midlife risk factors in women with and without previous GDM. MATERIAL AND METHODS: A prospective population-based cohort study was conducted of 3173 parous women from the Northern Finland Birth Cohort, 1966. Subjects were obtained from the national register or patient records. Those with a GDM diagnosis formed the GDM cohort (n = 271), and those without a previous GDM diagnosis formed the control cohort (n = 2902). Clinical examinations were performed on participants at the age of 46 and included anthropometric measurements, oral glucose tolerance test (OGTT), biochemical measurements, and cardiovascular assessment. RESULTS: At the age of 46, women in the GDM cohort had a higher body mass index (BMI, 29.0 kg/m2 vs 26.3 kg/m2, p < 0.001) and greater waist circumference (94.1 cm vs 86.5 cm, p < 0.001) than the control cohort. In the GDM cohort, a higher incidence of impaired glucose tolerance (12.6% vs 7.3%, p = 0.002), more previously diagnosed and OGTT-detected type 2 diabetes (23.3% vs 3.9%, p < 0.001), lower high-density lipoprotein (1.53 mmol/L vs 1.67 mmol/L, p = 0.011), higher triglycerides (1.26 mmol/L vs 1.05 mmol/L, p = 0.002) and a higher fatty liver index (6.82 vs 2.47, p < 0.001), were observed even after adjusting for BMI, polycystic ovary syndrome, parity, level of education, physical activity, smoking, and alcohol consumption. The women in the GDM cohort also had more MetS (42.6% vs 21.9%, p < 0.001) and higher risk scores for CVD and fatal events (Framingham 4.95 vs 3.60, p < 0.001; FINRISK 1.71 vs 1.08, p < 0.001). CONCLUSIONS: Women with a previous diagnosis of GDM exhibit more risk factors for CVD in midlife and are at a higher risk for cardiovascular events later in life.

Prevalence and Characteristics of Hidradenitis Suppurativa in the Northern Finland Birth Cohort 1986 Study: A Cross-sectional Study of 2,775 Subjects.

A negative stigmatization related to hidradenitis suppurativa may prevent patients from seeking care. Thus, a large proportion of patients with hidradenitis suppurativa may be missing from studies based on hospital data. The aim of this study was to examine the prevalence and characteristics of hidradenitis suppurativa among 2,775 subjects in the Northern Finland Birth Cohort 1986 Study (NFBC1986), who were in their mid-thirties. The prevalence of hidradenitis suppurativa was 4.0% (n = 110/2,775), being higher in females (4.8%) than in males (2.5%) (p < 0.01). Of those defined as having hidradenitis suppurativa in this study, only 4 cases (n = 4/110, 3.6%) were found to have a hidradenitis suppurativa diagnosis either in the hospital (Care Register for Health Care) or in the primary healthcare data. In an adjusted model in logistic regression analyses, hidradenitis suppurativa was significantly associated with obesity (body mass index 30-55 kg/m2) (odds ratio 3.81, 95% confidence interval 2.80-5.22), female sex (1.99, 1.53-2.61) and smoking (1.56, 1.21-2.00). In addition, there was an association between hidradenitis suppurativa and self-reported poor overall health status. Hidradenitis suppurativa seems to be common at the population level and only a minority of these patients seek care for the condition.

Adult Acne in Middle-age: Effects on Mental Health in General Population of the Northern Finland Birth Cohort 1966.

The impact of adult acne on patients' mental health has not been widely studied, and most studies have been conducted within specific patient populations. The current study examines the association between adult acne and psychological symptoms in the Northern Finland Birth Cohort 1966 (NFBC1966) (n = 1,907). The cohort members attended a health study at the age of 46 years, which comprised a whole-body examination performed by dermatologists to identify acne, and answering the Beck Depression Inventory II (BDI-II), Athens Insomnia Scale (AIS), Generalized Anxiety Disorder (GAD-7), State-Trait Anxiety Inventory (STAI) and 15-dimensional measure of health-related quality of life (15D HRQoL) questionnaires. The prevalence of adult acne was 7.9% (n = 150) with no statistical differences between the sexes. Cases with acne presented more (18.9%) depressive symptoms (BDI-II > 14 points) compared with those without acne (9.7%) (p < 0.001). In adjusted logistic regression analyses, those with acne had a 2-fold risk (odds ratio (OR) 2.08, 95% confidence interval (95% CI) 1.23-3.38) of having depressive symptoms compared with controls. In conclusion, when treating adult acne patients, it is important to recognize the increased risk of mental health symptoms.

Cross-sectional analysis of depressive symptom profiles and serum C-reactive protein levels: data from the Northern Finland 1966 birth cohort.

PURPOSE: Individuals with depression exhibit significantly higher levels of systemic inflammation than those without depression, particularly among those with atypical depression. However, this association has been less convincing at the population level among individuals without a formal depression diagnosis but with suggestive symptoms. Our aim was to clarify this association. MATERIALS AND METHODS: In a large birth cohort sample of the Finnish general population, we examined the cross-sectional association between high-sensitivity C-reactive protein (hsCRP) levels in venous blood samples and atypical/non-atypical depressive symptoms using the Beck Depression Inventory-II to screen 5443 middle-aged participants. RESULTS: As expected, depressive symptoms associated to elevated hsCRP-levels compared to non-depressed. Participants with the atypical subtype of depressive symptoms (n = 84) had an odds ratio (OR) of 2.59 (95% CI 1.40-4.81) for elevated hsCRP levels compared to the non-depressed group. Similarly, our findings indicate that participants with non-atypical symptoms (n = 440) also showed an OR of 1.42 (95% CI 1.05-1.92) when compared to the non-depressed group (n = 4919). CONCLUSIONS: These results provide additional support for previous research linking depression and inflammation and add to the field with a unique and sizeable study population. Furthermore, the current results support the notion that different types of depressive symptoms may be associated with inflammatory markers in slightly different ways.

Association of Rosacea with Depressive and Anxiety Symptoms: A General Population Study.

BACKGROUND: The association between rosacea and psychiatric comorbidity has been reported previously. However, there is a lack of general population studies about this subject area. OBJECTIVES: The aim of this study was to the association between rosacea with depressive and anxiety symptoms at the population level. METHODS: A clinical whole-body examination was performed by dermatologists for 1,932 subjects belonging to the Northern Finland Birth Cohort 1966 Study during the 46-year follow-up survey. The presence of depressive and anxiety symptoms was gathered by using validated Hopkins Symptom Checklist-25 (HSCL-25) included in the self-administered questionnaires. Binary logistic regression analysis was used to identify associations between rosacea and psychological symptoms. RESULTS: Rosacea was found in dermatological evaluation in 15.1% of the study subjects (n = 292). In logistic regression analyses, after adjusting for confounding factors, those with rosacea had 1.6-fold (OR 1.55, 95% CI: 1.02-2.32) risk for psychiatric symptoms according to HSCL-25 when compared with controls. In separate analyses of the HSCL-25 depression subscale, the risk was increased, especially for depressive symptoms (OR 1.56, 95% CI: 1.10-2.18). CONCLUSIONS: Patients with rosacea seem to have increased risk for depressive and anxiety symptoms in general population. Physicians treating patients with rosacea should pay more attention to the psychosocial health of patients.

Accurate diagnosis of bullous pemphigoid requires multiple health care visits.

Introduction: Accurate use of diagnostic codes is crucial for epidemiological and genetic research based on electronic health record (EHR) data. Methods: This retrospective study validated the International Classification of Diseases (ICD)-10 diagnostic code L12.0 for bullous pemphigoid (BP) using EHR data from two Finnish university hospitals. We found 1225 subjects with at least one EHR entry of L12.0 between 2009 and 2019. BP diagnosis was based on clinical findings characteristic of BP and positive findings on direct immunofluorescence (DIF), BP180-NC16A enzyme-linked immunosorbent assay (ELISA) or indirect immunofluorescence (IIF) assay. Results: True BP was found in 901 patients; the positive predictive value (PPV) for L12.0 was 73.6% (95% CI 71.0-76.0). L12.0 was more accurately registered in dermatology units than any specialized health care units (p<0.001). Including patients with multiple L12.0 registrations (≥3), increased the accuracy of the L12.0 code in both dermatology units and other settings. Discussion: One diagnostic code of L12.0 is not enough to recognize BP in a large epidemiological data set; including only L12.0 registered in dermatology units and excluding cases with <3 L12.0 record entries markedly increases the PPV of BP diagnosis.

Anxiety and depression in patients with hand eczema: A population-based study among 853 middle-aged subjects.

BACKGROUND: Hand eczema (HE) is a common dermatological disorder with considerable effect on the health-related quality of life (HRQoL). The data on mental comorbidities of HE is sparse and mostly studied among selected patient groups. OBJECTIVES: We aimed to investigate symptoms of depression and anxiety in patients with HE in general population. METHODS: Study subjects (n = 6695) belonging to the Northern Finland Birth Cohort 1966 Study (NFBC1966) responded to an extensive health questionnaire including questions about HE. Depression and anxiety symptoms were evaluated according to the Hopkins Symptom Checklist-25 (HSCL-25). RESULTS: Having ever suffered from HE was reported by 853 (12.8%) study subjects. Symptoms scores of depression were significantly higher among (n = 172, 20.3%) HE subjects compared with (n = 884, 15.4%) subjects without HE (Odds ratio [OR] 1.40, 95% confidence interval [CI]: 1.17-1.68, P < 0.001). Correspondingly, symptoms scores of anxiety were also more common among (n = 90, 10.6%) HE subjects than among (n = 448, 7.8%) subjects without HE (OR 1.40, 95% CI: 1.10-1.78, P = 0.007). In an adjusted model, the associations remained statistically significant (OR 1.30, 95% CI: 1.08-1.57, P = 0.007 and OR 1.34, 95% CI: 1.04-1.72, P = 0.021, respectively). CONCLUSIONS: Symptoms associated with mental health should be taken into account when managing patients with HE.

Former long-term use of combined hormonal contraception and glucose metabolism disorders in perimenopausal women: A prospective, population-based cohort study.

INTRODUCTION: Current use of combined hormonal contraceptives worsens glucose tolerance and increases the risk of type 2 diabetes mellitus at late fertile age, but the impact of their former use on the risk of glucose metabolism disorders is still controversial. MATERIAL AND METHODS: This was a prospective, longitudinal birth cohort study with long-term follow-up consisting of 5889 women. The cohort population has been followed at birth, and at ages of 1, 14, 31 and 46. In total, 3280 (55.7%) women were clinically examined and 2780 also underwent a 2-h oral glucose tolerance test at age 46. Glucose metabolism indices were analyzed in former combined hormonal contraceptive users (n = 1371) and former progestin-only contraceptive users (n = 52) and in women with no history of hormonal contraceptive use (n = 253). RESULTS: Compared with women with no history of hormonal contraceptive use, those who formerly used combined hormonal contraceptives for over 10 years had an increased risk of prediabetes (odds ratio [OR] 3.9, 95% confidence interval [CI]: 1.6-9.2) but not of type 2 diabetes mellitus. Former progestin-only contraceptive use was not associated with any glucose metabolism disorders. The results persisted after adjusting for socioeconomic status, smoking, alcohol consumption, parity, body mass index and use of cholesterol-lowering medication. CONCLUSIONS: Former long-term use of combined hormonal contraceptives was associated with a significantly increased risk of prediabetes in perimenopausal women, which potentially indicates a need of screening for glucose metabolism disorders in these women.

Sexual behavioral factors of the subjects visiting the clinic of sexually transmitted infections in Northern Finland: A cross-sectional study among 775 subjects.

Background and Aims: Sexually transmitted infections (STI) are among the most common infections globally. However, the sexual behavioral factors and sexual history of people visiting STI clinics have only been surveyed in a few studies. We aimed to evaluate the characteristics of the patients visiting the open STI clinic. Methods: This is a prospective observational study performed in the STI clinic in the premises of Department of Dermatology, Oulu University Hospital. All individuals (n = 775) attending the STI clinic between February and August 2022 were included to the study and the profile of the patients was evaluated. Results: We found that the majority of the STI clinic attendees (58.5%) were female. Mean age of the study population was 28.9 years, with females being significantly younger than males (p < 0.001). Only one-third (30.6%) of the patients reported having symptoms at the time of attending. Most commonly, patients had had one sex partner in the last 6 months. However, one-fifth (21.7%) reported several sex partners (over four). Almost half of the patients (47.6%) reported using a condom only randomly. Those with heterosexual orientation had fewer multiple-sex partners (p < 0.001) than those with homo- or bisexual orientation (p < 0.05). Conclusion: It is important to increase knowledge about the profile of STI clinic visitors to effectively target STI prevention on the groups at the highest risk of STIs.

Cardiovascular and Metabolic Profile of Subjects with Acne in a Cohort of Middle-aged Patients: A General Population Study of 1,932 Subjects.

Acne vulgaris is one of the most common inflammatory skin diseases, but there are few studies of adult acne and its association with general health. The aim of this study was to examine the prevalence and clinical characteristics of adult acne at the population level among 1,932 subjects belonging to the Northern Finland Birth Cohort 1966 Study. In addition, cardiovascular and metabolic profiles of acne cases and their controls were analysed. The prevalence of adult acne was 7.9% (n = 150) with no statistical difference between the sexes. The majority of subjects presented with papulopustular acne (77.1%). Comedo acne (10.8% of all subjects) was more common in females than in males (p < 0.005). Males with acne had more abnormality in their metabolic factors than did acne-free controls; plasma glucose and insulin levels at 60 min after the 75 g glucose load were higher in males with acne than in controls (p < 0.01 for both). Corresponding associations were not seen in females. In conclusion, adult acne is common in middle-age, presenting a slightly different clinical picture in females than in males. In addition, male subjects with acne may have a higher risk of metabolic disturbances than do controls, and thus, comprehensive evaluation of patients with adult acne is needed.

Characteristics, comorbidities, and treatment practices of lichen planus in Northern Finland: A register-based study among 619 subjects.

Background and Aims: Lichen planus (LP) is a common itching skin disease where lesions appear on the skin and mucous membranes. However, the epidemiology of LP is not yet sufficiently understood. The aim of this study was to retrospectively map out the characteristics, comorbidities and treatments of patients diagnosed with LP. Methods: This is a retrospective hospital patient registry-based study performed between 2009 and 2021 in a secondary care hospital (Oulu University Hospital) in Northern Finland. All patients with recorded diagnosis of LP were included in the study. Characteristics, comorbidities, and treatments of LP patients were studied. Results: In total, 619 patients were verified from the hospital health records. The mean age of patients was 54.2 years and the majority were female (58.3%). Most of the patients had symptoms in more than two skin areas (mean 2.7 skin areas), lower limbs being the most common site (74.0%). A third of patients (34.7%) had oral LP lesions. Nearly fifth (19.4%) of the subjects had a history of previous LP. Of comorbidities found among LP subjects, obesity (22.5%), malignancies (19.4%), depression (12.8%), and thyroiditis (12.4%) were seen more often than in general Finnish population. The most used form of treatment was topical corticosteroids (97.6%), followed by phototherapy 26.8%. Systemic treatments such as prednisolone and methotrexate had been used in 7.6% and 1.1% of the patients, respectively. Conclusion: LP patients had a heightened risk for several comorbidities, which should be considered when managing patients with LP.

Recurrent prescription of sleep medication among primary care patients with type 2 diabetes: an observational study of real-world registry data.

BACKGROUND: Little knowledge exists on the prevalence of recurrent sleep medication prescriptions among primary care patients with type 2 diabetes (T2D). Our aims were to examine the prevalence of recurrent sleep medication prescriptions and to elucidate the most often prescribed sleep medications in a Finnish primary care T2D population. METHODS: The study examined 4,508 T2D patients who consulted a primary health care center between 2011 and 2019 in Rovaniemi, Finland. All the data were retrieved from patient records, and recurrent sleep medication was defined as two or more prescriptions within the study period. We used the Chi-square and Kruskal-Wallis tests to compare patients who did and did not have recurrent sleep medication prescriptions. RESULTS: Altogether 28.1% of the T2D patients had been prescribed recurrent sleep medication. Benzodiazepine-like medication, melatonin, and mirtazapine were most often prescribed (to 56.9%, 44.4%, and 35.8%, respectively). Only 22.0% of the patients with recurrent sleep medication prescriptions had been diagnosed with a sleep disorder. CONCLUSIONS: Recurrent sleep medication prescriptions are frequent among primary care T2D patients. It seems that sleep disorders are underdiagnosed in relation to this. Primary care clinicians should carefully estimate the need for sleep medication when treating T2D patients' sleep problems and emphasize the diagnostic patterns of sleep problems.

Depression mediates the relationship between alexithymia and obesity in the Northern Finland Birth Cohort 1966 (NFBC1966).

BACKGROUND: The fact that a complex relationship exists between alexithymia and body mass index (BMI) is well established, but the underlying mechanisms remain poorly understood. Here, we explore the relationship between alexithymia and depressive symptoms in relation to adiposity measures, including the direct and indirect effect of alexithymia and depressive symptoms on obesity over a 15-year time-period, in the Northern Finland Birth Cohort 1966 (NFBC1966). METHODS: The study included individuals from the Northern Finland Birth Cohort 1966 (NFBC1966) who had available data for adiposity measures (body mass index and waist-to-hip ratio), alexithymia (measured by the 20-Item Toronto Alexithymia Scale: TAS-20), depressive symptoms (measured by the 13-item depression subscale of Hopkins Symptom Checklist: HSCL-13) at age of 31 years (n = 4773) and 46 years (n = 4431). Pearson's (r) correlation, and multiple linear regression were used to investigate the relationships between alexithymia, depressive symptoms, and adiposity measures. The potential mediating role of depressive symptoms was examined via Hayes' procedure (PROCESS). RESULTS: Positive correlations were confirmed between adiposity measures (BMI and WHR) and the TAS-20 score (and its subscale), but not between obesity and HSCL-13 score. The strongest correlation was between the DIF (difficulty identifying feelings) subscale of the TAS-20 and HSCL-13 at both time points (31 y: r(3013) = 0.41, p < 0.01, 46 y: r(3013) = 0.43, p < 0.01). Depressive symptoms completely (z = 2.55 (±0.00003), p = 0.01) and partly (z = 2.16 (±0.0001), p = 0.03) mediated the alexithymia-obesity relationship over the 15-year time-period. LIMITATIONS: Other psychological and environmental factors such as interoception, dietary intake and physical activities may also play a role as a potential mediating factor in alexithymia-obesity relationship. CONCLUSIONS: Our findings provide additional insights of theoretical framework of depressive symptoms mediation effect in the relationship between alexithymia and obesity. Alexithymia and depression should, therefore, be considered in the design of future clinical obesity research.

Association between Pruritus and Psychosocial Well-being: A Population-based Study among 6,809 Subjects.

Pruritus has an extensive impact on functional, social and psychosocial behaviour. The association between pruritus and psychological well-being has mostly been studied among selected patient groups, whereas population-based studies are lacking. The aim of this study was to determine the association between pruritus and insomnia, quality of life, depression and anxiety at the population level in the general population. A cross-sectional population-based study was conducted in 2012 to 2013. Study subjects (n = 6,809) belonging to the Northern Finland Birth Cohort 1966 Study participated in a large follow-up study at the age of 45-47 years. They completed an extensive health questionnaire including questions on pruritus and several previously validated questionnaires regarding symptoms of psychosocial well-being. Pruritus affected 19.9% of the study subjects weekly, being more common in women than in men (p < 0.001). A significant association was found between both localized and generalized pruritus and symptoms of insomnia, depression, anxiety and decreased quality of life. The association was seen even in those with mild psychological symptoms/insomnia, and it affected both sexes. The severity of psychological symptoms increased with increasing frequency of pruritus. In conclusion, pruritus has a multiple effect on psychosocial well-being. Physicians should consider possible psychosocial symptoms in patients with pruritus.

Associative factors for atopic dermatitis and other atopic diseases in middle-aged adults: A population-based birth cohort study among 5373 subjects.

Background and aims: The study aimed to examine parental, longitudinal and current associative factors for atopic dermatitis (AD) and to compare those to other atopic diseases in 46-year-old adults. Methods: Questionnaire data from the Northern Finland Birth Cohort 1966 study were used. To analyze allergic sensitization, skin prick tests (n = 5373) were performed for birch, timothy, cat, and house dust mite at age 46. Results: Maternal (odds ratio [OR] 1.81; 95% confidence interval [CI] 1.25-2.59) and paternal allergy (OR 2.54; CI 1.76-3.64), sensitization to any of the four tested aeroallergens (OR 1.56; CI 1.04-2.30) as well as polysensitization (OR 3.04; CI 2.10-4.37) were associated with current AD. Living on a farm in infancy was negatively associated with allergic rhinitis, allergic conjunctivitis, and atopic multimorbidity. Current AD (OR 2.65; CI 1.44-4.60) and all atopic diseases associated with indoor air related symptoms. Current AD associated with other atopic diseases, most strongly with allergic rhinitis (OR 4.92; CI 3.92-6.22). Conclusion: Current AD in a 46-year-old general population occurred frequently with allergic rhinitis, allergic conjunctivitis, and asthma in the Northern Finland Birth Cohort study 1966. Parental allergy and sensitization to common aeroallergens were found as shared associative factors for AD, allergic rhinitis, allergic conjunctivitis, and asthma. AD and other atopic diseases associated with symptoms related to poor indoor air quality. In daily practice, it is important to take these comorbidities into consideration when treating patients with AD.
