The role of childhood cumulative trauma in the risk of lifetime PTSD: An epidemiological study.

Cumulative trauma is usually devastating and can lead to severe psychological consequences, including posttraumatic stress disorder (PTSD). Exposure to various types of traumas, particularly during childhood, can be even more deleterious than the sheer number of events experienced. This epidemiological study is the first to investigate the impact of discrete childhood traumatic exposure on the risk of developing lifetime PTSD in a representative sample of the general population of the two biggest Brazilian cities. Participants were aged between 15 and 75 years old, living in São Paulo and Rio de Janeiro, Brazil, who had experienced traumatic events (N = 3,231). The PTSD diagnosis was assessed using the DSM-IV criteria through the version 2.1 of Composite International Diagnostic Interview. To operationalize childhood cumulative trauma, we considered the sum of 15 different childhood trauma categories that occurred before PTSD onset. The final multivariate logistic regression model indicated a strong relationship between the number of discrete types of childhood traumas and the likelihood of the lifetime PTSD development. The lifetime PTSD risk increased 28 % with each different type of childhood trauma when adjusted by confounds. Our study strengthens the evidence associating childhood cumulative trauma to increased lifetime PTSD risk.

The efficacy of internet-delivered cognitive-behavioral therapy for posttraumatic stress disorder according to the mean age of patients: a systematic review and meta-analysis.

Internet-delivered cognitive-behavioral therapy (I-CBT) is effective in treating post-traumatic stress disorder (PTSD) symptoms, offering enhanced accessibility and cost-effectiveness. However, it's important to note that these technologies may not be suitable for all age groups. Therefore, we conducted a systematic review and meta-analysis to determine if the effectiveness of I-CBT in treating PTSD varies based on the patients' mean age. We conducted a systematic review of the literature, focusing on randomized controlled trials (RCTs) in the ISI Web of Science, PubMed/MEDLINE, and PsycINFO databases. Following this, we performed a meta-analysis and evaluated the risk of bias using the Cochrane risk of bias quality assessment tool. In this study, we examined patient-related factors (civil or military status, age, and gender), clinical characteristics (baseline PTSD severity and type of trauma), and treatment characteristics (type of intervention, synchronous or asynchronous delivery, and the number of sessions) as independent variables. The dependent variable was the reduction in mean PTSD symptoms. Five RCTs out of 1,552 screened studies were included in this review, all of which showed some level of concern regarding potential bias. Our meta-analysis indicates that I-CBT is equally effective regardless of patients' mean age. Since all RCTs included only provide the mean age of the patients, further randomized controlled trials should address the effectiveness of I-CBT among different age groups.

Prevalence of dynapenia and overlap with disability, depression, and executive dysfunction.

OBJECTIVE: This study aims to investigate handgrip strength and dynapenia prevalence among older adults stratified by Brazilian macroregions. Additionally, we aim to evaluate the overlap between dynapenia and Instrumental Activities of Daily Living (IADL) disability, depression, and executive dysfunction on a national basis and by each Brazilian macroregion. METHODS: This cross-sectional analysis was based on data from the Brazilian Longitudinal Study of Aging (ELSI-Brazil). A multistage cluster sample design was used, with a representative population-based study of non-institutionalized community-dwelling Brazilians aged ≥ 50 years from 70 municipalities across all five macroregions of the country. The outcome variable was dynapenia. Covariables were IADL disability, depression, and executive dysfunction. The Brazilian macroregions were used for stratification. In addition, the following additional variables were included: age group, gender, education level, macroregions (North, Northeast, Southeast, South, and Midwest), self-reported health, multimorbidity, and falls. RESULTS: A total of 8,849 (94%) of the sample provided complete information for the handgrip strength assessment and were included in this analysis. Dynapenia prevalence was higher in North and Northeast regions (28.5% and 35.1%, respectively). We identified statistically significant differences between different macroregions for dynapenia, IADL disability, and verbal fluency, with worse values in the North and Northeast regions. In the North and Northeast macroregions, nearly half of the subjects that presented executive dysfunction and IADL disability also had dynapenia. There was a more significant overlap in the prevalence of all four conditions in the North and Northeast regions (4.8% and 5.5%, respectively), whereas the overlap was smaller in the South (2.3%). There was also a smaller overlap in the prevalence of dynapenia and depression in the South (5.8%) compared with other macroregions. CONCLUSIONS: Macroregions in Brazil exhibit marked differences in the prevalence of dynapenia and in its overlap with IADL disability, depression, and executive dysfunction.

Prevalence of sexual dysfunction in depressive and persistent depressive disorders: a systematic review and meta-analysis.

The aim of this study was to estimate the prevalence of sexual dysfunction in depressive disorders in individuals not in pharmacological treatment. For this purpose, we performed a systematic review and meta-analysis using the PRISMA guidelines, and the review was registered in PROSPERO (registration number CRD42020179709). Studies that evaluated sexual function and dysfunction in major depressive disorder (MDD) and persistent depressive disorder (PDD) were identified through searches in PubMed/Medline, Web of Science, PsychINFO, Scopus, and Scielo. Twelve cross-sectional studies were eligible. In women with MDD, the pooled prevalence rates of sexual impairment were: 47.22% (95% CI: 34.86-59.58) for arousal; 65.30% (95% CI: 45.86-84.73) for desire; 36.98% (95% CI: 28.42-45.54) for lubrication; 34.17% (95% CI: 17.87-50.46) for orgasm; and 33.91% (95% CI: 17.48-50.34) for sexual satisfaction. In men, the sexual impairment prevalence rates were: 26.45% (95% CI: 12.26-40.63) for arousal; 40.32% (95% CI: 22.19-58.46) for desire; 32.07% (95% CI: 26.14-37.99) for erection; 35.27% (95% CI: 5.13-65.41) for orgasm; and 23.05% (95% CI: 13.60-32.51) for sexual satisfaction. Overall sexual dysfunction was found in 82.75% of women (95% CI: 74.71-90.78) and 63.26% of men (95% CI: 52.83-73.69). Our results show that various sexual functions are impaired in MDD, making imperative the systematic evaluation of these alterations by clinicians. Future studies should be conducted, especially in PDD, to elucidate the role of these disorders in sexual function.

Prevalence of dynapenia and overlap with disability, depression, and executive dysfunction

CONCLUSIONS Macroregions in Brazil exhibit marked differences in the prevalence of dynapenia and in its overlap with IADL disability, depression, and executive dysfunction.

Impairment of Sexual Desire in Treatment-Resistant Depression: Prevalence and Correlates.

Objective: To assess sexual desire in patients with treatment-resistant depression (TRD).Methods: Baseline data were analyzed from an ongoing cohort study at an outpatient clinic specializing in TRD treatment in Brazil. The cohort comprised consecutive patients with the diagnosis of TRD who sought treatment at this center between November 2015 and January 2021. The Hamilton Depression Rating Scale (HDRS) genital symptoms item (item 14) was used as a proxy to assess sexual desire.Results: Sixty-five participants with TRD were included. There was sexual desire impairment in 67.7% of patients. Men (87.5%) were more affected than women (61.2%), and this difference was statistically significant (P = .05). Depression severity was associated with greater complaints of this aspect of sexual function (P < .01).Conclusions: Participants with TRD had a high prevalence of sexual desire impairment, which was associated with greater depressive symptom severity and male sex. The findings suggest that health care professionals should systematically assess sexual desire in patients with TRD in daily clinical practice. Further longitudinal studies are needed in larger samples using specific instruments for assessing sexual dysfunction and comparing TRD and non-TRD populations.

Stuck in a Moment: Tonic Immobility Predicts Poor Quality of Life in Treated PTSD Patients.

BACKGROUND: Posttraumatic stress disorder (PTSD) is a prevalent and disabling multisystem disorder, with significant physical and psychiatric morbidity and poor quality of life (QOL). Although peritraumatic reactions - tonic immobility and dissociation - are established predictors of PTSD severity and development, there is a dearth of investigation assessing the impact of peritraumatic reactions on QOL of PTSD patients. Quality of life has become increasingly important in health care and research as a reliable outcome measure. It comprises psychological, physical, social and environmental domains, providing important information about the impact of diseases on patient's life. This study aims to investigate the impact of peritraumatic tonic immobility and peritraumatic dissociation on QOL of PTSD civilian outpatients. SUBJECTS AND METHODS: It is a cross-sectional study of 50 victims of urban violence with current PTSD, recruited in a specialized outpatient clinic. Instruments used were: Structured Clinical Interview IV, Peritraumatic Dissociative Experiences Questionnaire, Tonic Immobility Scale and WHOQOL-BREF (psychological, physical, social and environmental domains). Linear regression models were fitted to evaluate the impact of peritraumatic reactions - tonic immobility and dissociation - on WHOQOL-BREF scores. We controlled for sex as potential confounding. RESULTS: The severity of peritraumatic tonic immobility negatively impacted on psychological and environment domains of quality of life. For each additional point on the Tonic Immobility Scale, there was a decreased of 0.8 points on the scores of these domains of WHOQOL-BREF. Neither the peritraumatic reactions showed effects on physical nor social domains. Possible limitations of this study include cross-sectional design, relatively small sample size of tertiary center outpatients and recall bias. CONCLUSIONS: Peritraumatic tonic immobility is related to poor quality of life, adding new insights about the relationship between this immobility reaction and PTSD.

To BDZ or not to BDZ? That is the question! Is there reliable scientific evidence for or against using benzodiazepines in the aftermath of potentially traumatic events for the prevention of PTSD? A systematic review and meta-analysis.

BACKGROUND: Most international guidelines suggest that benzodiazepines (BDZs) may be inefficient or iatrogenic in the aftermath of a potentially traumatic event (PTE). The goal of this study was to assess the strength of the evidence on whether the use of BDZs in the aftermath of a PTE negatively affects the incidence and severity of post-traumatic stress disorder (PTSD). METHODS: We systematically scrutinized the ISI Web of Knowledge, MEDLINE, SCOPUS, and PTSDpubs electronic databases in addition to citation searching. We included original studies providing data about the development of PTSD in adults after BDZ administration in the aftermath of a PTE. We screened 387 abstracts and selected eight studies for the qualitative synthesis and seven for the meta-analysis. We performed two separate meta-analyses, one for randomized clinical trials (RCTs) and the other for cohort studies. Heterogeneity between studies was evaluated with Higgins I² statistic and tested using the χ². This study was registered at PROSPERO (number 127170). RESULTS: The meta-analysis of the cohort studies showed an increased risk of PTSD in patients who received BDZs compared to those who did not (risk ratio (RR) = 1.53; 95% confidence interval (CI): 1.05-2.23) with a modest heterogeneity among studies (I2 = 41.8, p = 0.143). Regarding the RCTs, the combined measure revealed a tendency toward an increased severity of the PTSD symptoms (standardized mean difference (SMD): 0.24; 95% CI: 0.32-0.79). CONCLUSION: The studies reviewed showed a possible harmful effect of BDZs when used immediately after a PTE. However, these conclusions were based on a small number of studies of poor to moderate methodological quality.

Chikungunya Fever: Comparison Study of Synovitis and Tenosynovitis of the Hands and Wrists Using Physical Examination, Ultrasound, and MRI Findings.

OBJECTIVES: To compare musculoskeletal changes on a physical examination (PE), ultrasound (US) and magnetic resonance imaging (MRI) of the hands and wrists of patients with Chikungunya fever (CF). METHODS: The sample consisted of 30 patients in the chronic phase of CF. The sites analyzed were the interphalangeal (IP), metacarpophalangeal (MCP) and wrist/mediocarpal (WMC) joints and periarticular soft tissue. The interval between the PE and imaging tests was 7 days, and the interval between US and MRI was 2 days. The kappa coefficient was calculated to estimate the agreement between the PE and US and MRI findings and between the US and MRI findings. RESULTS: Significant agreement was observed between PE and US in the diagnosis of synovitis. The only statistically significant agreement between US and MRI was the finding of flexor tenosynovitis; the agreement was moderate. CONCLUSIONS: US has great potential for use in diagnosing synovitis suspected based on a PE. The limited agreement observed between US and MRI, in turn, may suggest a complementary role of these methods.

An evaluation of binge eating characteristics in individuals with eating disorders: A systematic review and meta-analysis.

The objective of this review is to provide an updated synthesis of studies in individuals with eating disorders that examined the following components of binge eating episodes (BEEs): caloric intake, episode duration, and also the association of BEE size with psychopathology. A systematic review and meta-analysis were performed following the PRISMA guidelines. Searches were conducted on PubMed, PsycINFO, Scopus, SciELO, ScienceDirect and ProQuest databases. Meta-analysis was performed using random effects models and meta-regression. Forty-three studies were included. There was a paucity of information regarding BEE in individuals with anorexia nervosa. The pooled caloric intake of participants with bulimia nervosa (BN) during BEE in laboratory studies was significantly greater in comparison to the caloric intake during BEE in clinical studies [(3070 (95%CI 2596, 3544) vs. 1789 (95%CI 1498, 2081)], respectively. In participants with binge eating disorder (BED), the pooled means were 2088 (95%CI 1819, 2358) kcal in laboratory studies and 1903 (95%CI 1622, 2184) kcal in clinical studies, with no statistically significant difference between groups. Overall, BEE had a mean duration of 37.3 min in participants with BN and 41.7 min in those with BED. We found a positive correlation between the average caloric intake and level of depression (ß = 55.5; p = 0.019). BEE in individuals with BN or BED were characterized by the consumption of extremely large quantities of calories. This was mainly found in laboratory studies of individuals with BN. BEE had a mean duration of less than 1 h in individuals with BN or BED. BEE size was positively associated with depression severity. Future research should explore the relevance of binge size as a core component of binge eating in clinical samples, in males, and in pediatric populations.

Prevalence and psychiatric comorbidities of intermittent explosive disorders in Metropolitan São Paulo, Brazil.

PURPOSE: To estimate the prevalence of intermittent explosive disorder (IED) in comorbidity with other psychiatric disorders and to describe the temporal sequencing of disorders in the São Paulo Metropolitan Area, Brazil. METHODS: Data from the São Paulo Megacity Mental Health Survey, a population-based study of 5037 adult individuals, were analyzed. The World Health Organization Composite International Diagnostic Interview (CID 3.0) was used to assess lifetime DSM-IV disorders, including IED, with a response rate of 81.3%. RESULTS: The majority (76.8%) of respondents with IED meet the criteria for at least one other psychiatric disorder, with a prevalence almost twice as high as that observed in individuals without IED. The prevalence of any anxiety, mood, impulse control or substance use disorders in respondents with IED was more than two times higher compared to those without IED, with prevalence ratios ranging from 2.1 (95% CI 1.74-2.48) to 2.9 (95% CI 2.12-4.06). The diagnosis of IED occurred earlier than most of the other mental disorders, except for those with usual onset in early childhood, as Specific and Social Phobias and Attention Deficit Disorder. CONCLUSION: Considering that IED is a highly comorbid disorder and has an earlier onset than most other mental comorbidities in the Brazilian general population, these results may be useful in guiding governmental mental health actions.

Dorsomedial Prefrontal Cortex Repetitive Transcranial Magnetic Stimulation for Tinnitus: Promising Results of a Blinded, Randomized, Sham-Controlled Study.

OBJECTIVES: Tinnitus is the perception of sound in ears or head without corresponding external stimulus. Despite the great amount of literature concerning tinnitus treatment, there are still no evidence-based established treatments for curing or for effectively reducing tinnitus intensity. Sham-controlled studies revealed beneficial effects using repetitive transcranial magnetic stimulation (rTMS). Still, results show moderate, temporary improvement and high individual variability. Subcallosal area (ventral and dorsomedial prefrontal and anterior cingulate cortices) has been implicated in tinnitus pathophysiology. Our objective is to evaluate the use of bilateral, high frequency, dorsomedial prefrontal cortex (DMPFC) rTMS in treatment of chronic subjective tinnitus. DESIGN: Randomized placebo-controlled, single-blinded clinical trial. Twenty sessions of bilateral, 10 Hz rTMS at 120% of resting motor threshold of extensor hallucis longus were applied over the DMPFC. Fourteen patients underwent sham rTMS and 15 were submitted to active stimulation. Tinnitus Handicap Inventory (THI), visual analog scale, and tinnitus loudness matching were obtained at baseline and on follow-up visits. The impact of intervention on outcome measures was evaluated using mixed-effects restricted maximum likelihood regression model for longitudinal data. RESULTS: A difference of 11.53 points in the THI score was found, favoring the intervention group (p = 0.05). The difference for tinnitus loudness matching was of 4.46 dB also favoring the intervention group (p = 0.09). CONCLUSIONS: Tinnitus treatment with high frequency, bilateral, DMPFC rTMS was effective in reducing tinnitus severity measured by THI and matched tinnitus loudness when compared to sham stimulation.

Pattern evolution of antidepressants and benzodiazepines use in a cohort.

OBJECTIVE: In recent decades there has been an increase in the use of antidepressants (AD) and a decrease in the use of benzodiazepines (BDZ). Prevalence, cumulative incidence, and factors associated with the incidence of AD and BDZ use in a Brazilian population were estimated in this article. METHODS: Data were collected with a self-administered questionnaire in a cohort of employees from a university in Rio de Janeiro. The prevalence of the use of AD and BDZ was calculated for 1999 (4,030), 2001 (3,574), 2006-07 (3,058), and 2012 (2,933). The cumulative incidences of the use of AD and BDZ between 1999 and 2007 were estimated by the Poisson models with robust variance estimates. RESULTS: In 1999, the prevalence of the use of AD and BDZ were 1.4% (95%CI: 1.1-1.8) and 4.7% (95%CI: 4.1-5.4), respectively; in 2012, they were 5.4% (95%CI: 5.5-6.2) and 6.8% (95%CI: 6.0-7.8). The incidence of use, between 1999 and 2007, was 4.9% (95%CI: 4.2-5.7) for AD and 8.3% (95%CI: 7.3-9.3) for BDZ. The incidences of AD and BDZ use were higher among women and participants with a positive General Health Questionnaire. CONCLUSION: In this population, the increase in the use of AD was not accompanied by a decrease in the use of BDZ, showing the prescriptions for psychotropic medication do not follow the currently recommended guidelines for treatment of common mental health disorders.

Effects of Blood Pressure Lowering Agents on Cardiovascular Outcomes in Weight Excess Patients: A Systematic Review and Meta-analysis.

BACKGROUND: Obesity hypertension is an ongoing pandemic. The first-line medications to treat this condition are still subject to debate. We compared diuretics, calcium-channel blockers (CCB), beta-blockers (BB), angiotensin-converting enzyme inhibitors (ACEI) and angiotensin receptor blockers (ARB) as an initial antihypertensive therapy for prevention of cardiovascular morbimortality of hypertensive individuals who are overweight or obese. METHODS: We conducted a search of the literature for randomized clinical trials in which at least 50% of the participants were overweight or obese. The primary outcomes were all-cause mortality, cardiovascular mortality, acute myocardial infarction (MI), heart failure (HF), stroke, or end-stage renal disease. RESULTS: Our search yielded 16 randomized studies. Comparisons of two classes of drugs with at least two studies indicated that (1) CCB and ACEI increased the risk of HF [relative risk (RR) = 2.26; 95% confidence interval (CI) 1.16-4.40] and stroke [hazard ratio (HR) = 1.13; 1.00-1.26]), respectively, compared to diuretics; and (2) CCB showed a reduction in stroke (HR = 0.77; 0.66-0.89) and total mortality (HR = 0.94; 0.87-1.01) compared to the BB atenolol. Comparisons of two classes of antihypertensive medications with only one study showed that the risk of MI was higher with ARB valsartan versus CCB (HR = 1.19; 95% CI 1.02-1.38, p = 0.02). In contrast, losartan lowered the risk of a composite cardiovascular outcome compared to atenolol (HR = 0.87; 95% CI 0.77-0.98, p = 0.02). CONCLUSIONS: In hypertensive subjects with excess weight, diuretics are more effective for preventing HF and stroke than CCB and ACEI, respectively. CCB are a good first-line choice for prevention of cardiovascular disease, except HF.

Comorbidity in post-traumatic stress disorder: A population-based study from the two largest cities in Brazil.

BACKGROUND: This study investigated the patterns of comorbidity between PTSD and depression, other anxiety disorders, alcohol-related disorders using the DSM-IV and ICD-10 criteria. The temporal sequence of the comorbid diagnoses was also investigated. METHODS: We used data from a large population-based survey carried out between 2007 and 2008 in the two largest cities in Brazil: São Paulo and Rio de Janeiro. RESULTS: Diagnoses of depression, other anxiety disorders, and alcohol-related disorder were more prevalent in the people with PTSD than in those without PTSD. Using the DSM-IV criteria, approximately 67% of cases presenting PTSD were also diagnosed with another mental disorder. The diagnosis category of other anxiety disorders presented the highest proportion of comorbidity (53%). Depression was found in 34% person with PTSD whilst alcohol-related disorders were observed in 7%. Considering the temporal relationship, the onset of comorbid depression was uniformly distributed through the periods before, within the same year and after PTSD's onset. When other anxiety disorders were comorbid with PTSD, in almost 90% of the cases the other anxiety disorders preceded PTSD. For comorbidity between of alcohol-related disorders and PTSD, in 50% of the cases alcohol-related disorders preceded the diagnosis of PTSD. LIMITATIONS: The cross-sectional design imposes limitations on establishing a temporal relationship between the onset of psychiatric disorders due to memory bias. CONCLUSIONS: Our findings indicate that among individuals presenting comorbid PTSD and other anxiety disorders, this diagnosis tend to precede PTSD. Comorbid cases are more frequent and more severe, and this should be taken into account in therapeutic research and clinical practice.

[Aggregation of cardiovascular risk factors: alcohol, smoking, excess weight, and short sleep duration in adolescents in the ERICA study]. / Agregação dos fatores de risco cardiovascular: álcool, fumo, excesso de peso e sono de curta duração em adolescentes do estudo ERICA.

This study aimed to analyze the aggregation of alcohol consumption, smoking, excess weight, and short sleep in Brazilian adolescents. This was a cross-sectional multicenter study conducted with teens participating in the Study of Cardiovascular Risk Factors in Adolescents (ERICA in Portuguese). The sample consisted of adolescents that answered the complete questionnaires on sleep, tobacco, and alcoholic beverages, in addition to having their weight and height measured. Aggregation was analyzed by comparing the observed and expected prevalence of risk factors in all possible groupings, with the respective 95% confidence intervals. Analyses were performed in Stata 14 using the svy (survey) command for complex sample data. The sample included 73,624 adolescents, of whom 25.5% had excess weight and 24.2% consumed alcoholic beverages. Aggregation of the four risk factors was O/E = 5.6. Aggregation of three factors was more prevalent in those 15 to 17 years of age (P = 4.8). In the POR (prevalence odds ratio) analysis of the combination of two risk factors, those that smoked showed 11.80 higher odds of also consuming alcohol, compared to those that did not smoke, and vice versa, in private schools. In relation to age, adolescents 12 to 14 years of age that smoked showed 15.46 times higher odds of also drinking, and vice and versa. Adolescents in the sample presented the aggregate presence of four risk factors, and there was a significant relationship between tobacco and alcohol consumption.

O objetivo foi analisar a agregação do consumo de álcool, tabaco, excesso de peso e sono curto em adolescentes brasileiros. Trata-se de estudo transversal, multicêntrico realizado com base em adolescentes participantes do Estudo de Riscos Cardiovasculares em Adolescentes (ERICA). A amostra foi composta por adolescentes que responderam completamente aos questionários sobre sono, tabaco e uso de bebidas alcoólicas, além de terem realizado antropometria com medidas de peso e estatura aferidas. A agregação foi analisada comparando a prevalência observada com a esperada dos fatores de risco em todas as possibilidades de agrupamento, e seus intervalos de 95% de confiança. As análises foram realizadas no programa estatístico Stata 14, mediante uso do comando svy (survey) para dados de amostra complexa. São 73.624 adolescentes, 25,5% dos estudantes apresentam excesso de peso e 24,2% fazem uso de bebida alcoólica. A agregação dos quatro fatores de risco foi de O/E = 5,6. A prevalência de agregação dos três fatores foi maior naqueles com 15 a 17 anos (P = 4,8). Na análise de ORP (odds ratio de prevalência) da combinação de dois fatores de risco, observou-se que os fumantes têm 11,80 vezes mais chances de também beber quando comparados àqueles que não fumam e vice-versa, nas escolas privadas. Em relação à idade, adolescentes com 12 e 14 anos que fumam têm 15,46 vezes mais chances de também beber e vice-versa. Adolescentes estudados apresentam a presença dos quatro fatores de forma agregada e há relação significativa entre o tabaco e o consumo de álcool.

Son 73.624 adolescentes, un 25,5% de los estudiantes presentan exceso de peso y un 24,2% consumen bebidas alcohólicas. La agregación de los cuatro factores de riesgo fue de O/E = 5,6. La prevalencia de agregación de los tres factores fue mayor en aquellos con 15 a 17 años (P = 4,8). En el análisis de ORP (odds ratio de prevalencia) de la combinación de dos factores de riesgo, se observó que aquellos que fuman tienen 11,80 veces más oportunidades de beber también, cuando los comparamos con aquellos que no fuman y viceversa en las escuelas privadas. En relación con la edad, los adolescentes con 12 y 14 años que fuman tienen 15,46 veces más oportunidades de también beber y viceversa. Los adolescentes estudiados presentan la presencia de los cuatro factores de forma agregada y existe una relación significativa entre tabaco y el consumo de alcohol.

Is weight regain after bariatric surgery associated with psychiatric comorbidity? A systematic review and meta-analysis.

Bariatric surgery has been recognized as the gold standard treatment for severe obesity. Although postbariatric surgery patients usually achieve and maintain substantial weight loss, a group of individuals may exhibit weight regain. Several factors are proposed to weight regain, including psychiatric comorbidity. The objective of the study is to conduct a systematic review and meta-analysis of studies investigating the relationship between psychiatric comorbidity and weight regain. A systematic review through PubMed, Web of Science, Cochrane Library, Scopus, and PsycINFO was performed, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). After a stepwise selection, 13 articles were included in the qualitative analysis and 5 were included for a meta-analysis. Women was majority in most of the studies (87.6%), and a bypass procedure was the bariatric intervention most evaluated (66.8%), followed by gastric banding (32.1%) and sleeve (1.1%). Higher rates of postbariatric surgery eating psychopathology were reported in patients with weight regain. However, the association between general psychopathology and weight regain was not consistent across the studies. In the meta-analysis, the odds of eating psychopathology in the weight regain group was higher compared with the nonweight regain group (OR = 2.2, 95% CI 1.54-3.15). Postbariatric surgery eating psychopathology seems to play an important role in weight regain.

[Underestimation of obesity and overweight based on self-report measures in the general population: prevalence and a proposal for correction models]. / Subestimativa de obesidade e sobrepeso a partir de medidas autorrelatadas na população geral: prevalência e proposta de modelos para correção.

The study's objectives: compare self-report measures of weight and height with direct measures; assess the impact of these discrepancies on body mass index (BMI) and prevalence of overweight and obesity; and apply correction models to the self-report measures and assess the degree of improvement in the corrected measures produced with the use of these models. A cross-sectional study was performed, assessing 4,151 adults (18 to 60 years) participating in the São Paulo Megacity Epidemiological Study. Linear regression models stratified by sex were proposed for correction of self-reported measures. Agreement was assessed with the intraclass correlation coefficient for the direct measures, self-report measures, and corrected measures, and kappa coefficient for BMI classification categories. Self-reported weight and the resulting BMI were underestimated, while height was overestimated, compared to direct measures. With all the correction models, the corrected measures were closer to the direct measures. Prevalence rates for excess weight, calculated by self-report measures, were underestimated by 24% in men and by 28% in women; with corrections, the underestimation decreased to 8% and 10%, respectively. The results showed moderate agreement for self-report measures and substantial agreement for corrected measures compared to direct measures. The use of correction equations for self-report data proved to be a useful method for producing more trustworthy estimates of prevalence of overweight and obesity in the general population, usually estimated from self-report measures of weight and height in population surveys.

Os objetivos deste artigo são: (i) comparar medidas autorrelatadas de peso e estatura com medidas aferidas; (ii) avaliar o impacto dessas discrepâncias sobre o índice de massa corporal (IMC) e as prevalências de sobrepeso e obesidade; e (iii) aplicar modelos de correção das medidas autorrelatadas e avaliar o grau de melhoria das medidas corrigidas produzidas pelo uso desses modelos. Realizou-se estudo transversal, com avaliação de 4.151 adultos (18 a 60 anos) participantes do Estudo Epidemiológico dos Transtornos Mentais São Paulo Megacity. Foram propostos e testados modelos de regressão linear estratificados por sexo, para a correção das medidas autorrelatadas. Para avaliar a concordância, usou-se o coeficiente de correlação intraclasse para as medidas aferidas, medidas autorrelatadas e medidas corrigidas, bem como o coeficiente kappa para as categorias de classificação do IMC. O peso autorrelatado e o IMC resultantes foram subestimados, ao passo que a estatura foi superestimada, comparados às medidas aferidas. Com todos os modelos de correção, as medidas corrigidas tornaram-se mais próximas às medidas aferidas. As prevalências de excesso de peso, quando calculadas a partir das medidas autorrelatadas, estavam subestimadas em 24% em homens e 28% em mulheres. Com as correções, a subestimativa diminuiu para 8% e 10%, respectivamente. Identificou-se concordância moderada para as medidas autorrelatadas e concordância substancial para as medidas corrigidas, quando comparadas às medidas reais. O uso de equações de correção para dados autorrelatados mostrou-se um método útil para produzir estimativas mais fidedignas da prevalência de excesso de peso e obesidade na população geral, geralmente estimadas a partir de medidas de peso e estatura autorrelatadas nos inquéritos populacionais.

Los objetivos fueron: comparar medidas autoinformadas de peso y estatura con medidas evaluadas; evaluar el impacto de estas discrepancias sobre el índice de masa corporal (IMC) y las prevalencias de sobrepeso y obesidad; y aplicar modelos de corrección de las medidas autoinformadas y evaluar el grado de mejoría de las medidas corregidas, producidas por el uso de esos modelos. Se realizó un estudio transversal evaluando a 4.151 adultos (18 a 60 años), participantes en el Estudio Epidemiológico São Paulo Megacity. Se propusieron y probaron modelos de regresión lineal estratificados por sexo para la corrección de las medidas autoinformadas. Para evaluar la concordancia, se usó el coeficiente de correlación intraclase para las medidas evaluadas, medidas autoinformadas y medidas corregidas, y el coeficiente kappa para las categorías de clasificación del IMC. El peso autoinformado y el IMC resultantes fueron subestimados mientras la estatura fue sobrestimada, comparados con las medidas evaluadas. Con todos los modelos de corrección, las medidas corregidas se convirtieron en más cercanas a las medidas evaluadas. Las prevalencias de exceso de peso, cuando se calculan a partir de las medidas autoinformadas, estaban subestimadas en un 24% en hombres y un 28% en las mujeres; con las correcciones, la infravaloración disminuyó a un 8% y un 10%, respectivamente. Se identificó una concordancia moderada para las medidas autoinformadas y una concordancia sustancial para las medidas corregidas, cuando se compararon con las medidas reales. El uso de ecuaciones de corrección para dados autoinformados se mostró un método útil para producir estimaciones más fidedignas de la prevalencia de exceso de peso y obesidad en la población general, generalmente estimadas a partir de medidas de peso y estatura autoinformadas en las encuestas poblacionales.

[Exposure to breastfeeding and common mental disorders in adolescence]. / Exposição ao aleitamento materno e transtornos mentais comuns na adolescência.

This article sought to evaluate the effect of exposure, and exposure time, to breastfeeding on the occurrence of common mental disorders (CMD) among Brazilian adolescents enrolled in school. This study analyzed data from the Study of Cardiovascular Risk in Adolescents (ERICA), evaluating those whose questionnaire regarding breastfeeding had been filled out by parents or guardians. The presence of CMD was identified using the General Health Questionnaire, version 12 items (GHQ-12), and we considered two cutoff points (scores ≥ 3 and ≥ 5). We tested the associations in bivariate analyses and through multiple logistical regression models, adjusting for potential confounding variables. Of the 41,723 adolescents we evaluated, most were students of the female sex (54.6%), aged between 12 and 15 years (71%), attended public schools (83.1%), resided in the Southeastern region (51.9%) and belonged to the economic classes B (53.8%) and C (34.1%). Around half of the adolescents' mothers had not completed their secondary education (51.7%). The group of adolescents who were breastfed for more than six months (51.8%) had a lower CMD prevalence for both GHQ-12 cutoff points, when compared with the group who were not breastfed or who were breastfed for ≤ 1 month (IR = 0.82; 95%CI: 0.69-0.97 and IR = 0.74; 95%CI: 0.59-0.91 for 3 and 5 points, respectively). Prolonged breastfeeding seems to play a protective role on the occurrence of CMD in adolescence.

O objetivo foi avaliar o efeito da exposição e do tempo de exposição ao aleitamento materno na ocorrência de transtornos mentais comuns (TMC) entre adolescentes escolares brasileiros. Este trabalho analisou dados do Estudo de Riscos Cardiovasculares em Adolescentes (ERICA), avaliando aqueles que tiveram o questionário referente ao aleitamento materno respondido pelos pais ou responsáveis. A presença de TMC foi identificada pelo General Health Questionnaire, versão 12 itens (GHQ-12), considerando-se dois pontos de corte (escores ≥ 3 e ≥ 5). As associações foram testadas em análises bivariadas e por meio de modelos de regressão logística múltipla, com ajustes por variáveis potenciais de confusão. Dentre os 41.723 adolescentes avaliados, a maioria foi composta por estudantes do sexo feminino (54,6%), que tinham idades entre 12 e 15 anos (71%), estudavam em escolas públicas (83,1%), residiam na Região Sudeste (51,9%) e eram das classes econômicas B (53,8%) e C (34,1%). Cerca de metade das mães dos adolescentes não tinha o ensino médio completo (51,7%). O grupo de adolescentes com mais de seis meses de aleitamento materno (51,8%) apresentou uma menor prevalência de TMC para os dois pontos de corte do GHQ-12 avaliados, quando comparado com o grupo que não recebeu aleitamento materno ou que o recebeu por período ≤ 1 mês (RI = 0,82; IC95%:0,69-0,97 e RI = 0,74; IC95%: 0,59-0,91 para 3 e 5 pontos, respectivamente). O aleitamento materno prolongado parece desempenhar um papel protetor para a ocorrência de TMC na adolescência.

El objetivo fue evaluar el efecto de la exposición y del tiempo de exposición a la lactancia materna en la ocurrencia de trastornos mentales comunes (TMC) entre adolescentes escolares brasileñas. Este trabajo analizó datos del Estudio de Riesgos Cardiovasculares en Adolescentes (ERICA), evaluando aquellos, cuyo cuestionario -referente a la lactancia materna- había sido respondido por los padres o responsables legales. La presencia de TMC fue identificada por el General Health Questionnaire, versión 12 ítems (GHQ-12), considerándose dos puntos de corte (puntuaciones ≥ 3 y ≥ 5). Las asociaciones fueron probadas en análisis bivariados, y a través de modelos de regresión logística múltiple, con ajustes por variables potenciales de confusión. Entre los 41.723 adolescentes evaluados, la mayoría estuvo compuesta por estudiantes que eran del sexo femenino (54,6%), que tenían una edad entre 12 y 15 años (71%), estudiaban en escuelas públicas (83,1%), residían en la región Sudeste (51,9%) y eran de las clases económicas B (53,8%) y C (34,1%). Cerca de la mitad de las madres de los adolescentes no contaba con la enseñanza media completa (51,7%). El grupo de adolescentes con más de seis meses de lactancia materna (51,8%) presentó una menor prevalencia de TMC para los dos puntos de corte del GHQ-12 evaluados, cuando se comparan con el grupo que no recibió lactancia materna o que la recibió durante un período ≤ 1 mes (RI = 0,82; IC95%: 0,69-0,97 y RI = 0,74 y IC95%: 0,59-0,91 para 3 y 5 puntos, respectivamente). La lactancia materna prolongada parece desempeñar un papel protector para la ocurrencia de TMC en la adolescencia.
