AIM To examine the associations between mental disorders and infectious, atopic, inflammatory diseases while adjusting for other risk factors.METHODS We used data from PsyC oL aus, a large Swiss Population Cohort Study(n = 3720; age range 35-66). Lifetime diagnoses of mental disorders were grouped into the following categories: Neurodevelopmental, anxiety(early and late onset), mood and substance disorders. They were regressed on infectious, atopic and other inflammatory diseases adjusting for sex, educational level, familial aggregation, childhood adversities and traumatic experiences in childhood. A multivariate logistic regression was applied to each group of disorders. In a complementary analysis interactions with sex were introduced via nested effects. RESULTS Associations with infectious, atopic and other chronic inflammatory diseases were observable together with consistent effects of childhood adversities and familial aggregation, and less consistent effects of trauma in each group of mental disorders. Streptococcal infections were associated with neurodevelopmental disorders(men), and measles/mumps/rubella-infections with early and late anxiety disorders(women). Gastric inflammatory diseases took effect in mood disorders(both sexes) and in early disorders(men). Similarly, irritable bowel syndrome was prominent in a sex-specific way in mood disorders in women, and, moreover, was associated with early and late anxiety disorders. Atopic diseases were associated with late anxiety disorders. Acne(associations with mood disorders in men) and psoriasis(associations with early anxiety disorders in men and mood disorders in women) contributed sex-specific results. Urinary tract infections were associated with mood disorders and, in addition, in a sex-specific way with late anxiety disorders(men), and neurodevelopmental and early anxiety disorders(women).CONCLUSION Infectious, atopic and inflammatory diseases areimportant risk factors for all groups of mental disorders. The sexual dimorphism of the associations is pronounced. 展开更多

Self-compassion refers to a positive, kind attitude of a person toward oneself when confronted with difficulties. A self-compassionate coping style may buffer against the development of psychological problems. Aim was to introduce a new, 4-item measure for Self-compassion and to test its psychometric properties. In addition, its relationships with Neff’s Self Compassion Scale (SCS) and with the HADS depression and anxiety scales were studied, in an adult general population sample. The results showed that the SCCM had a high reliability, confirming internal validity. In addition, the SCCM was strongly related to all subscales and total score of the SCS, suggesting construct validity. Finally, also strong relationships were found with symptoms of depression and anxiety, suggesting criterion validity. The SCCM might therefore be considered a valuable and reliable tool in the study of self-compassion associated with mental-health problems, while it also might provide us with targets for intervention. 展开更多

The effects of physical exercises combined with a low-calorie diet on weight loss, body composition, lipoproteins profile, and physical fitness had been well described. However, Central Africa’s studies investigating these kinds of diets and exercise regimens are lacking. Objective. To investigate the effects of adding 14-weeks exercises to a hypocaloric diet on changes in body composition, lipoproteins concentrations, and physical capacities in obese Congolese women. Population and Methods. In total, 34 obese women aged 30 - 39 years (mean age: 33.7 ± 2.4 years) assigned to 14-weeks training program and low energy ketogenic diet. Body composition was assessed using classic methods and impedancemetry. Fasting plasma glucose (FPG) and fasting serum insulin were assessing using enzymatic colorimetric and radioim-munoradiometric methods. HOMA-IR and lipoproteins concentrations were assessed using standardized laboratory methods. VO2peak was measured on a treadmill during a progressive exercise test. Speed, cadence and stride length were measured along the 10-m level walkway. Muscular endurance was measured using the tests of sit-up and inflections-extensions of elbows. All the variables of the study were assessed at the beginning, in the 7-weeks, and in the 14-weeks of training methods. Results. Declines in body weight (16%), percent fat (12.1%), fat weight (26.4%), abdominal fat (34.2%), and waist circumference (10.4%) were found. A significant decrease in FPG (13%), fasting serum insulin (60.9%), HOMA-IR (64.7%), total cholesterol (12.2%), LDL-cholesterol (20.3%), triglycerides (92.8%), and VLDL-triglycerides (17.5%) was shown. In contrast, significant increase in HDL-cholesterol (27.13%) was found. The peak oxygen consumption VO2peak relative to body weight improved more in the 14-weeks training program (13.4%). Obese women exhibited higher values in the 14-weeks training program for speed gait (16.5%), cadence (9.1%), and stride length (15.7%) during normal walk and rapid walk. Weight loss combined with a low-calorie diet and 14-weeks training program improved significantly muscular endurance capacities. Conclusion. Exercise added to hypocaloric diet leads to decreases in body composition, to improve in insulin sensitivity, to enhancement of VO2peak and functional fitness. This may be helpful for the treatment of the metabolic complications of abdominal obesity. 展开更多
