- The epidemiology of personality disorders in the Sao Paulo Megacity general population(2018) SANTANA, Geilson Lima; COELHO, Bruno Mendonca; WANG, Yuan-Pang; CHIAVEGATTO FILHO, Alexandre Dias Porto; VIANA, Maria Carmen; ANDRADE, Laura HelenaIntroduction Most studies on the epidemiology of personality disorders (PDs) have been conducted in high-income countries and may not represent what happens in most part of the world. In the last decades, population growth has been concentrated in low-and middle-income countries, with rapid urbanization, increasing inequalities and escalation of violence. Our aim is to estimate the prevalence of PDs in the Sao Paulo Metropolitan Area, one of the largest megacities of the world. We examined sociodemographic correlates, the influence of urban stressors, the comorbidity with other mental disorders, functional impairment and treatment. Methods A representative household sample of 2,942 adults was interviewed using the WHO-Composite International Diagnostic Interview and the International Personality Disorder Examination-Screening Questionnaire. Diagnoses were multiply imputed, and analyses used multivariable regression. Results and discussion Prevalence estimates were 4.3% (Cluster A), 2.7% (Cluster B), 4.6% (Cluster C) and 6.8% (any PD). Cumulative exposure to violence was associated with all PDs except Cluster A, although urbanicity, migration and neighborhood social deprivation were not significant predictors. Comorbidity was the rule, and all clusters were associated with other mental disorders. Lack of treatment is a reality in Greater Sao Paulo, and this is especially true for PDs. With the exception of Cluster C, non-comorbid PDs remained largely untreated in spite of functional impairment independent of other mental disorders. Conclusion Personality disorders are prevalent, clinically significant and undertreated, and public health strategies must address the unmet needs of these subjects. Our results may reflect what happens in other developing world megacities, and future studies are expected in other low- and middle-income countries.
- Gender-related patterns of psychiatric disorder clustering among bariatric surgery candidates: A latent class analysis(2018) DUARTE-GUERRA, Leorides Severo; COELHO, Bruno Mendonca; SANTO, Marco Aurelio; LOTUFO-NETO, Francisco; WANG, Yuan-PangBackground: Psychiatric disorders tend to distribute unevenly in women and men with severe obesity. The current research aimed to identify homogeneous clusters of concurrent psychiatric disorders among patients seeking bariatric surgery, by gender. Methods: We recruited a consecutive sample of 393 candidates with obesity (311 women and 82 men) in a university-based bariatric center. Trained clinicians assessed psychiatric disorders through the Structured Clinical Interview for DSM-IV (SCID). Latent class analysis categorized pre-surgical patients into uniform clusters of co-occurring psychiatric disorders. Results: For both genders, the 3-class psychopathological clustering was the best-fitting solution. Among women, the latent classes were: (1) ""oligosymptomatic"", wherein 42% of patients showed low probability of psychiatric disorders; (2) ""bipolar with comorbidities"", in 33%; and (3) ""anxiety/depression"", in 25%. Among men, (1) ""bipolar with comorbidities"" was found in 47% of patients; (2) ""oligosymptomatic"", in 40%; and (3) ""anxiety/depression"", in 13%. For both genders, the probability of presenting eating disorders was higher in both ""bipolar"" and ""anxiety/depression"" classes. Substance use disorders was prominent among ""bipolar"" men. In comparison with ""oligosymptomatic"" class, the likelihood of higher BMI was observed among ""bipolar"" men and poorer work attainment among men with ""anxiety/depression"". Limitation: Participants was cross-sectionally drawn from a single bariatric center. Conclusions: Pre-surgical men and women with severe obesity were distributed in three comorbidity profiles and revealed analogous psychopathological patterns. The class of ""bipolar disorders"" most likely presented comorbidity with eating and substance use disorder. This natural clustering of psychiatric disorders among bariatric patients suggests gender-related therapeutic approaches and surgical outcomes.
- Gender-related dimensions of childhood adversities in the general population(2018) COELHO, Bruno M.; SANTANA, Geilson L.; VIANA, Maria C.; ANDRADE, Laura H.; WANG, Yuan-PangObjective: Childhood adversities (CAs) comprise a group of negative experiences individuals may suffer in their lifetimes. The goal of the present study was to investigate the cluster discrimination of CAs through psychometric determination of the common attributes of such experiences for men and women. Methods: Parental mental illness, substance misuse, criminality, death, divorce, other parental loss, family violence, physical abuse, sexual abuse, neglect, physical illness, and economic adversity were assessed in a general-population sample (n=5,037). Exploratory and confirmatory factor analysis determined gender-related dimensions of CA. The contribution of each individual adversity was explored through Rasch analysis. Results: Adversities were reported by 53.6% of the sample. A three-factor model of CA dimensions fit the data better for men, and a two-factor model for women. For both genders, the dimension of family maladjustment - encompassing physical abuse, neglect, parental mental disorders, and family violence - was the core cluster of CAs. Women endorsed more CAs than men. Rasch analysis found that sexual abuse, physical illness, parental criminal behavior, parental divorce, and economic adversity were difficult to report in face-to-face interviews. Conclusion: CAs embrace sensitive personal information, clustering of which differed by gender. Acknowledging CAs may have an impact on medical and psychiatric outcomes in adulthood.
