RESUMO
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.

HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) is a chronic disabling disease. However, there is a lack of an adequate and specific health measurement instrument validated and with good performance to assess their degree of physical disability. This led us to carry out this study and to evaluate the performance of Fiocruz's National Institute of Infectious Diseases (IDS) disability scale, a specific instrument for HAM/TSP. Ninety-two HAM/TSP patients participated in the study. One researcher applied the IDS, IPEC scale, Disability Status Scale (DSS), Expanded DSS (EDSS), Osame scale, Beck Depression Inventory, and the WHOQOL-BREF questionnaire. In parallel, blindly, and separately, other researchers applied the IDS. An inter-rater reliability analysis of the IDS, correlation analysis with the other scales, and depression and quality of life questionnaires were performed. The applicability of the IDS was also evaluated. The IDS showed high reliability in all scores. The inter-rater reliability test for the total IDS score was 0.94 (0.82-0.98) on its four dimensions. The scale adequately indicated the different degrees of disability, presenting a distribution similar to normal. There was a high correlation with the other scales (Spearman coefficients > 0.80, p < 0.001). The scale had good acceptance among users and a short application time. IDS for HAM/TSP was reliable, consistent, easy, and fast to use. It can be used for both prospective evaluations and clinical trials. The present study supports the IDS as a valid instrument to measure disability in patients with HAM/TSP compared to previously used scales.

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.

BACKGROUND/OBJECTIVE: Although telemedicine use has been under discussion for decades, this topic has gained unprecedented importance during the COVID-19 pandemic. The Rheumatoid Arthritis Disease Activity Index (RADAI) is a user-friendly tool, fully self-administered, to assess rheumatoid arthritis (RA) disease activity. The aim of this study was to compare the performance of RADAI with other disease activity indices, functional status, and inflammatory markers in a large cohort of RA patients. METHODS: We assessed the concurrent validity of RADAI against Clinical Disease Activity Index (CDAI), Disease Activity Score in 28 Joints-C-reactive protein, Disease Activity Score in 28 Joints-erythrocyte sedimentation rate, Simplified Disease Activity Index, and physician assessment of disease activity and the correlation of RADAI with Health Assessment Questionnaire-Disability Index and inflammatory markers at the REAL Study baseline. We also evaluated the correlation of the change in RADAI and the change in CDAI over a 6-month follow-up. RESULTS: From the 1115 patients included in the REAL Study, 1113 had RADAI scores in the first assessment. At baseline, correlations between RADAI and other disease activity indices were strong, ranging from 0.64 (comparison with physician assessment) to 0.79 (comparison with CDAI). Correlation between the change in RADAI score over the 6 months of follow-up and the change in CDAI score over the same period was moderate/strong for the overall group and within the stratified analyses. CONCLUSION: The strong correlation of RADAI with other well-established tools for disease activity measurement reassures its use with RA patients' follow-up, especially in this new era of telemedicine.

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.

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.

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.

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.

There is an increasing interest in the study of the aggregation of risk factors for noncommunicable chronic diseases. However, there are no studies among adolescents stratified by alcohol use. This study investigated the aggregation of cardiovascular risk factors in adolescents considering the use or not of alcohol. A total of 73,624 Brazilian adolescents aged 12-17 years from public and private schools were evaluated in a national cross-sectional study (March-2013 to December-2014). The aggregation of cardiovascular risk factors was the main outcome. The regression model was adjusted for sex, age, region of Brazil, and school type. Most alcohol users were 16 to 17 years old, while nonusers were between 12 and 13 years. Alcohol users showed a higher prevalence of smoking (8.1% vs. 0.8%) and sleep inadequacy (59.9% vs. 51.4%) than nonusers did. On the other hand, a sufficient level of physical activity was more frequent among alcohol users (51.2% vs. 44.2%). The presence of only one cardiovascular risk factor was more frequent in nonusers (42.3%) than alcohol users (38.9%). Alcohol users tended to aggregate more for the category of 3-4 cardiovascular risk factors when compared with the non-alcohol-using population (10.9% vs. 7.9%). Aggregation of three cardiovascular risk factors was more likely to be observed among male adolescent alcohol users. Inadequate sleep and smoking habit tended to aggregate among alcohol users. This finding highlights the importance of public policies aiming to reduce alcohol consumption at early ages and, consequently, to decrease the risk of future morbimortality of noncommunicable chronic diseases.

BACKGROUND: This study aimed to compare the effects of aerobic training (AT), strength training (ST) and low-intensity exercise in a control group (CG) as adjunct treatments to pharmacotherapy for major depressive disorder (MDD) in older persons. METHODS: Older persons clinically diagnosed with MDD (n = 27) and treated with antidepressants were blindly randomized into three groups: AT, ST and a CG. All patients were evaluated prior to and 12 weeks after the intervention. RESULTS: Compared with the CG, the AT and ST groups showed significant reductions in depressive symptoms (treatment -response = 50% decrease in the pre- to postintervention assessment) through the Hamilton Depression Rating Scale (AT group: χ2, p = 0.044) and Beck Depression Inventory (ST group: χ2, p = 0.044). CONCLUSION: Adding AT or ST with moderate intensity to the usual treatment promoted a greater reduction of MDD symptoms.

PURPOSE: The purpose of the study is to identify early vulnerabilities for psychiatric disorders among Brazilian elementary school children, controlling for familial and community adversities. METHODS: This is a cross-sectional study examining the association between child psychiatric disorders and potential early vulnerabilities (disability, low intellectual quotient, and negative dimensions of the temperament trait self-directedness (low resourcefulness, low purposefulness, low enlightened second nature), controlling for the potential confounders: familial and community adversities. SAMPLE: Four probabilistic samples of second-to-sixth grade students from public schools in four towns from different Brazilian regions (N = 1620). The following instruments were applied: the K-SADS-PL (to assess child/adolescent psychiatric disorders); the Ten-Question Screen (to measure child disability); three structured questions used as proxy of self-directedness; and the reduced version of the WISC-III to measure IQ. To evaluate familial/community adversities: Self-Report Questionnaire-SRQ-20 (to assess maternal/primary caretaker anxiety/depression); questions derived from structured questionnaires (to measure child abuse, marital physical violence, neighborhood violence); Brazilian Association of Research Companies questionnaire (to evaluate poverty/socioeconomic status). Trained psychologists interviewed mothers/primary caretakers and evaluated children/adolescents individually. RESULTS: A final logistic regression model showed that children/adolescents with low resourcefulness, low purposefulness, low enlightened second nature, lower IQ and disability were more likely to present any child psychiatric disorders. CONCLUSION: Early vulnerabilities such as low IQ, presence of disability, and dimensions of temperament were associated with psychiatric disorders among Brazilian elementary school children, after controlling for familial and ecological confounders. These early vulnerabilities should be considered in mental health prevention/intervention programs in low-middle-income countries like Brazil.

Neonaticide is the killing of a neonate on the day of its birth by his/her own mother. Neonaticidal women were reported to be predominantly young, unmarried, and primiparous. The motive for murdering the newborn relates to the shame, the fear of rejection, and abandonment by significant others, and the social stigmas associated with an illegitimate birth. The goal of the present study was to conduct a systematic review of the scientific literature and identify population-based studies reporting the incidence of neonaticide in different countries. A total of 485 abstracts were screened. After applying the inclusion/exclusion criteria, 10 studies were selected. Additional searches identified two more articles. Most of these studies were from Europe, where incidence varied from 0.07 (Finland, 1980-2000 period) to 8.5 neonaticides per 100000 births (Austria, 1975-2001 period). More recent studies have indicated that a growing proportion of neonaticidal women are married, multiparous, and suffers from mental disorders. Preventive measures, such as anonymous free delivery, were shown to reduce the incidence of neonaticide, although this effect may be short-lived. Despite social and institutional changes, neonaticide persists even in the most socially advanced, liberal, and prosperous societies in the world.

BACKGROUND: Teenagers and young adults are more exposed to violence and traumatic events than adults, and these factors can be associated with mental disorders. This paper aims at investigating whether young people are more exposed to violence and traumatic events and to compare pattern of mental disorders with adults. METHODS: Cross-sectional study using the Composite International Diagnostic Interview, conducted between 2007 and 2008 with a randomly selected sample of 15 to 75 year-old residents of São Paulo, Brazil. RESULTS: Two thousand five hundred thirty-six participants were divided into two groups: 1096 (43.2 %) young people (15 to 24 years), and 1440 (56.8 %) adults (25 to 75 years). 12-month exposure to traumatic events was higher among young people (32.1 % vs. 20.6 %; p < 0.001). Assaultive violence was reported by 13.4 % of young people and 8.6 % of adults (p = 0.012); 20.1 % of young people and 13 % of adults reported suffering other injury or shocking events (p < 0.001); sudden death/life threatening illness of a close person was declared by 6.1 % of young people and 3.2 % of adults (p = 0.017). Prevalence of alcohol related disorders was higher among young people (5.4 % vs. 2.5 %; P = 0.032); depressive disorders were more prevalent among adults (9.0 % vs. 4.7 %; P = 0.004). Alcohol related disorders were associated to assaultive violence among young people (OR = 3.4; 95 % CI = 1.36 to 8.52; p = 0.004) and adults (OR = 2.38; 95 % CI = 1.23 to 4.61; p = 0.002). Phobic/anxiety disorders were associated to other injury or shocking events among young people (OR = 1.28; 95 % CI = 0.67 to 2.44; p = 0.025). Major depressive disorder was associated to assaultive violence among young people (OR = 2.27; 95 % CI = 1.09 to 4.74; p = 0.004) and adults (OR = 1.28; 95 % CI = 0.85 to 1.93; p = 0.009). CONCLUSION: Exposure to violence and traumatic events was higher among young people. Alcohol related disorders, depression and phobic/anxiety disorders were significantly higher among young people exposed to traumatic events. Despite the study design, high exposure to violence and traumatic events in this age group can be considered important factors in triggering mental disorders in this vulnerable age period.

OBJECTIVES: To compare locus of control and coping strategies in older persons with and without depression. METHOD: This cross-sectional study included 144 depressed in-patients from seven psychogeriatric hospital units, and 106 community-dwelling older persons without depression. All participants were 60 years and older. Locus of control was assessed by a 17-items self-report questionnaire with six response categories. Coping strategies were assessed by a 26-items self-report questionnaire with five response categories. For analytical purposes, age (<75 years vs. ≥75 years), level of education (<10 years vs. ≥10 years) and general medical health (poor vs. not poor) were categorized. RESULTS: In linear regression analysis, controlling for demographics, health, and social variables, the depressed in-patients showed a higher external locus of control orientation and a less frequent use of problem-focused coping strategies compared with the non-depressed group. No differences in use of emotion-focused strategies were found between the two groups. CONCLUSION: Compared with the non-depressed old persons, the depressed hospitalized older persons were characterized by perceptions of less personal control, and less use of problem-focused strategies, what also might have brought positive alterations into their situation.

BACKGROUND: Both exaggerated and diminished reactivity to stress can be maladaptive. Previous studies have shown that performing increasingly difficult tasks leads first to increased reactivity and then to a blunted response when success is impossible. Our aim was to investigate the influence of trait anxiety on cardiac and cortisol response to and recovery from a standardized psychosocial stress task (Trier Social Stress Task) in a homogeneous sample of healthy peacekeepers. We hypothesized that participants with higher trait anxiety would show blunted reactivity during the performance of an overwhelmingly difficult and stressful task. Participants (N = 50) delivered a speech and performed an arithmetic task in the presence of critical evaluators. Cortisol samples and electrocardiogram data were collected. Participants completed the State-Trait Anxiety Inventory-Trait version, the Posttraumatic Stress Disorder Checklist-Civilian Version (PCL-C) and the Military Peace Force Stressor Inventory. RESULTS: For heart rate, the findings showed that peacekeepers with higher trait anxiety reacted less to the speech task (p = 0.03) and to the arithmetic task (p = 0.008) than those with lower trait anxiety. Trait anxiety did not modulate cortisol responses to the task. Despite the high trait anxiety group having higher PCL-C scores than the low trait anxiety group (p < 0.0001), this did not influence the cardiac results. CONCLUSIONS: We concluded that individuals with higher trait anxiety had less tachycardia in response to acute psychological stress than those with lower trait anxiety. The present results point to a higher risk for more anxious individuals of a maladaptive reaction to stressful events.

BACKGROUND: There is a dearth of literature dealing with the impact of the severity of posttraumatic symptoms and of comorbid mental disorders on the health-related quality of life (HRQOL) of victims of civilian violence with a primary diagnosis of PTSD. OBJECTIVES: To investigate the influence of the severity of posttraumatic symptoms and of presence of comorbid mental disorders on the HRQOL of treatment-seeking outpatients with PTSD. METHODS: A sample of 65 PTSD patients was recruited in a specialized outpatient clinic. The volunteers had the diagnoses of PTSD and of comorbid mental disorders established with the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I). The severity of posttraumatic, depression and anxiety symptoms was measured with the PCL-C, BDI and BAI, respectively. HRQOL was assessed by means of the SF-36, a 36-item self-administered scale that measures eight domains of quality of life: vitality, physical functioning, bodily pain, general health perceptions, physical role functioning, emotional role functioning, social role functioning, and mental health. Multiple linear regression models were fitted to investigate the relationship between the severity of posttraumatic, mood, and anxiety symptoms; the presence of specific current comorbid disorders and of psychotic symptoms, and the number of current comorbid conditions for each of the eight domains of HRQOL, after adjusting for the effect of sociodemographic characteristics. RESULTS: The severity of PTSD symptoms predicted worse HRQOL in all eight domains of SF-36, even after controlling for the severity of depression and anxiety symptoms, the presence of panic disorder, OCD, specific and social phobia, psychotic symptoms, and the number of comorbid disorders. The strongest negative association between PTSD symptoms severity and HRQOL was found in the Social Functioning domain. Although the inclusion of the depressive symptoms in the models led to a reduction of the magnitude of the negative association between the severity of PTSD symptoms and the HRQOL domain scores, the former still accounted for most of the explained variance of the latter. CONCLUSIONS: We found that even in the presence of comorbid mental disorders, the severity of posttraumatic symptoms remained the strongest predictor for impaired HRQOL in PTSD outpatients. Our results suggest that improvement of HRQOL should be considered a therapeutic objective and an essential outcome measure in the treatment of PTSD.

BACKGROUND: Tonic immobility is an involuntary response to inescapable life-threatening events. Peritraumatic tonic immobility has been reported in convenience samples of female victims of sexual assault and in mixed-gender victims of different types of trauma. This study evaluated peritraumatic tonic immobility in a representative general population sample and its association with posttraumatic stress disorder (PTSD) and gender. METHODS: 3231 victims of traumatic events aged 15-75 years responded to the Tonic Immobility Scale. PTSD and traumatic events were assessed using the Composite International Diagnostic Interview (CIDI 2.1). We calculated the means and the standard deviations of Tonic Immobility Scale scores stratified by PTSD and gender. The association between tonic immobility scores and gender was explored controlling for potential confounders through a multiple linear regression model. RESULTS: Tonic immobility scores were more than double in those who met criteria for PTSD and were almost four points higher in women. Gender differences remained statistically significant even after adjustment for confounding variables. LIMITATIONS: The cross-sectional and retrospective design may have given rise to recall bias. Results presented here may not apply to small and medium rural areas and the CIDI 2.1 can lead to a certain degree of misclassification. CONCLUSIONS: We have expanded the scope of previous investigations on peritraumatic tonic immobility which were based on convenience samples only, showing its occurrence in victims of traumatic events using a large representative sample of the general population. Furthermore, we confirmed in an unbiased sample the association between peritraumatic tonic immobility and PTSD and female gender.

PURPOSE: To investigate the prevalence of low back pain (LBP) and the association with home posture habits while watching TV and using the computer in adolescents. METHODS: This is a cross-sectional study with high school adolescents in Rio de Janeiro, Brazil. Students answered questions regarding sociodemographic variables, lifestyle, posture (illustration), time watching TV, time using computer, time playing video game and the presence and impact of LBP. Multivariate logistic regression was used to investigate the association between home posture habits and LBP. RESULTS: The prevalence of LBP was 46.8 % (18.2 % chronic low back pain [CLBP] and 28.6 % acute low back pain [ALBP]). As LBP consequence, 23 % (n = 253) of the students took medication, 9.1 % (n = 100) missed classes and 8.2 % (n = 90) sought a physician. Slump postures while watching TV and using the desktop computer were associated with CLBP (OR 3.22, 95 % CI 1.38-7.5 and OR 1.7, 95 % CI 1.06-2.73, respectively). Participants who watched TV seated in bed yielded an OR of 2.14 (95 % CI 1.06-4.32) for ALBP and who used the notebook lying belly down in bed yielded an odds ratio (OR) of 2.26 (95 % CI 1.02-5.01) for ALBP. Among confounding factors, female sex was associated with CLBP and ALBP, work (no) was a protective factor associated with ALBP. CONCLUSION: Our findings support the high prevalence and the substantial impact of LBP in late adolescence and add the association with inappropriate home postural habits.

BACKGROUND: Potentially traumatic events happen in people's lives, leading to the risk of the development of posttraumatic stress disorder, depression and even suicide. Resilience is an individual's ability to maintain or regain his/her mental health in the face of significant adversity or risk of death. The aim of this study was to conduct a systematic review of studies evaluating the effectiveness of resilience promotion interventions in adults. METHODS: Electronic searches were conducted in databases ISI, PsycINFO and PubMed, including every language and every year until January 20, 2013. We selected studies with nonclinical samples of adults that evaluated the effectiveness of the intervention through randomized and non-randomized controlled trials and open-ended studies. We also considered valid constructs directly related to resilience, such as hardiness. RESULTS: Among 2.337 studies, 13 were selected for the review, 5 through electronic databases and 8 through search in references or the "times cited list" (list of articles that cited the selected papers). Of these, 7 are randomized controlled trials, 5 non-randomized controlled trials, and one an open-ended trial. Most of the studies included reported some degree of improvement in resilience-like variables among those subjects exposed to resilience-promoting programs. Furthermore, positive findings were more consistent among randomized controlled trials--six out of the seven suggested efficacy. CONCLUSION: There is evidence pointing towards some degree of effectiveness of resilience promotion programs, despite the poor operationalization of the construct and great heterogeneity in the studies. Indeed, the analysis of the methodological quality of the selected studies was hampered by the poor quality of reporting. There were faults in reporting in most studies on almost all items (random sequence generation, allocation concealment, blinding of outcome assessment, incomplete outcome data, description of concurrent treatment and intent-to-treat analysis), except for the item "selective reporting". Additional efforts should be made to determine the actual effect size of the interventions, since this is crucial for calculating the cost-effectiveness of resilience promotion strategies.
