Recent research has suggested an increase in the global prevalence of psychiatric symptoms during the COVID-19 pandemic. This study aimed to assess whether lifestyle behaviors can predict the ...presence of depression and anxiety in the Brazilian general population, using a model developed in Spain.
A web survey was conducted during April-May 2020, which included the Short Multidimensional Inventory Lifestyle Evaluation (SMILE) scale, assessing lifestyle behaviors during the COVID-19 pandemic. Depression and anxiety were examined using the PHQ-2 and the GAD-7, respectively. Elastic net, random forest, and gradient tree boosting were used to develop predictive models. Each technique used a subset of the Spanish sample to train the models, which were then tested internally (vs. the remainder of the Spanish sample) and externally (vs. the full Brazilian sample), evaluating their effectiveness.
The study sample included 22,562 individuals (19,069 from Brazil, and 3,493 from Spain). The models developed performed similarly and were equally effective in predicting depression and anxiety in both tests, with internal test AUC-ROC values of 0.85 (depression) and 0.86 (anxiety), and external test AUC-ROC values of 0.85 (depression) and 0.84 (anxiety). Meaning of life was the strongest predictor of depression, while sleep quality was the strongest predictor of anxiety during the COVID-19 epidemic.
Specific lifestyle behaviors during the early COVID-19 epidemic successfully predicted the presence of depression and anxiety in a large Brazilian sample using machine learning models developed on a Spanish sample. Targeted interventions focused on promoting healthier lifestyles are encouraged.
Few studies have used a multidimensional approach to describe lifestyle changes among undergraduate students during the COVID-19 pandemic or have included controls. This study aimed to evaluate ...lifestyle behaviors and mental health of undergraduate students and compare them with an age and sex-matched control group. A cross-sectional web survey using snowball sampling was conducted several months after the beginning of COVID-19 pandemic in Spain. A sample of 221 students was recruited. The main outcome was the total SMILE-C score. Students showed a better SMILE-C score than controls (79.8 + 8.1 vs. 77.2 + 8.3; p < 0.001), although these differences disappeared after controlling for covariates. While groups did not differ in the screenings of depression and alcohol abuse, students reported lower rates of anxiety (28.5% vs. 37.1%; p = 0.042). A lower number of cohabitants, poorer self-perceived health and positive screening for depression and anxiety, or for depression only were independently associated (p < 0.05) with unhealthier lifestyles in both groups. History of mental illness and financial difficulties were predictors of unhealthier lifestyles for students, whereas totally/moderate changes in substance abuse and stress management (p < 0.05) were predictors for the members of the control group. Several months after the pandemic, undergraduate students and other young adults had similar lifestyles.
Reproducibility in Science is challenging and may be hard to achieve in alcohol research. Previous general population surveys in Brazil have estimated the prevalence of alcohol dependence to be ...around 10%. We aim to estimate alcohol use and dependence using different methods and definitions.
The 3rd Brazilian Household Survey on Substance Use (BHSU-3) was a nationwide, probability sample survey that interviewed 16,273 individuals. DSM-IV-TR criteria were used to determine alcohol dependence. In the BHSU-2 (covering only Brazil’s 108 largest municipalities), alcohol dependence was defined as fulfilling 2/6 DSM-III criteria. Using the BHSU-3 data, alcohol use was estimated at: 1 the national level, 2 BHSU-2 municipalities, taking into consideration the sample design, and 3 BHSU-2 municipalities, ignoring the sample design. Alcohol dependence was calculated using: BHSU-3 and BHSU-2 definitions, two denominators (A population and B 12-month drinkers), and 1, 2, 3.
Lifetime alcohol use ranged from 66.4% (95%CI:64.8–68.0 1) to 70.1% (95%CI:69.1–71.0, 3). The estimated population presenting with alcohol dependence ranged from N = 2.3 million (BHSU-3 definition, 1) to N = 4.3 million (BHSU-2 definition, 1). In the first case, the prevalence among the general population A and drinkers B was 1.5% (95%CI:1.2–1.8) and 3.5% (95%CI:2.8–4.2), respectively. In second case, prevalence was 2.8% (95%CI:2.4–3.3, A) and 6.6% (95%CI:5.6–7.6, B).
Prevalence of alcohol dependence may vary as much as 4.3 times, analyzing the same dataset in different ways. Brazilian research on alcohol is funded by governmental research and policy-making agencies, providing subsidies for alcohol policy in the country. It is crucial that sufficient methodological information is provided in order to guarantee reproducibility and consistency over time.
Comprehensive care for sexual and reproductive health (SRH) and social needs for women living with HIV remains limited globally. We aimed to assess trends in baseline sociodemographic, clinical, ...sexual, and reproductive characteristics among a cohort of HIV-infected women in Rio de Janeiro from 1996 to 2016. Participants were stratified into four time periods based on year of enrollment; we compared cross-sectional data from each period. Of 1361 participants (median age 36), most were black or mixed race (60.1%), unemployed (52.1%), and without secondary education (54%). Adolescent pregnancy was common (51.5%), and 18.3% reported sexual debut at < 15 years old. Nearly half (45.2%) had < 5 lifetime sexual partners, yet prior syphilis and oncogenic human papillomavirus prevalence were 10.9% and 43.1%, respectively. Lifetime prevalence of induced abortion was 30.3%, and 16% used no contraceptive method. Future research should explore interactions between social vulnerability, HIV, and poor SRH outcomes and healthcare models to alleviate these disparities.
Prior studies on substance use in Brazil have not focused on opioid misuse, previously thought to be nearly non-existent. This paper presents new findings on heroin and non-medical use of opioid ...analgesics. Data come from the 2015 Brazilian Household Survey on Substance Use (BHSU-3), a nationally representative survey estimating epidemiological parameters related to substance use by residents across Brazil. BHSU-3 used stratified multi-stage probability sampling across multiple geographic domains of interest, resulting in 16,273 interviews with household residents. Lifetime heroin use among Brazilians was 0.3 (95% C.I:0.2-0.4). Lifetime, past-year, and past-month non-medical use of opioid analgesics were respectively 2.9 (95%C.I.:2.3-3.4), 1.4 (95%C.I.:1.1-1.7) and 0.6 (95%C.I.:0.4-0.8). Past-year prevalence of non-medical opioid analgesics use was lower among males Prevalence Ratio (PR): 0.54 (95% C.I.:0.36-0.78), those aged 12-24 0.56 (95% C.I.:0.34-0.92), persons with monthly family incomes between R$1,501-3,000 0.59 (95% C.I.:0.38-0.92) or greater than R$3,000 0.64 (95% C.I.:0.42-0.98), and persons who were unemployed 0.65 (95% C.I.:0.46-0.92). Non-medical use of opioids in Brazil may be more prevalent than previously recognised. Proper measurement and evaluation of opioid misuse across Brazil and other Latin American countries is critical to understand and prevent opioid-related harms.
To evaluate satisfaction and burden of mental health personnel providing mental health services for substance users and their families.
Five hundred twenty-seven mental health workers who provide ...treatment for substance users in five Brazilian states were interviewed. Data on sociodemographic characteristics and measures of satisfaction (SATIS-BR) and burden of mental health personnel (IMPACTO-BR) were collected.
Type of mental health service and educational attainment were associated with degree of satisfaction and burden. Therapeutic community workers and those with a primary education level reported being more satisfied with the treatment offered to patients, their engagement in service activities, and working conditions. Workers from psychosocial care centers, psychosocial care centers focused on alcohol and other drugs, and social care referral centers (both general and specialized), as well as workers with a higher education, reported feeling overburdened.
This study offers important information regarding the relationship of mental health personnel with their work. Care providers within this sample reported an overall high level of job satisfaction, while perceived burden differed by type of service and educational attainment. To our knowledge, this is the first study with a sample of mental health professionals working with substance users across five Brazilian states.
INTRODUCTIONLifestyle Medicine comprises six domains: diet, substance use, physical activity, stress management, social connection, and sleep. The comprehensive assessment of lifestyle is ...challenging, but the "Short Multidimensional Inventory on Lifestyle Evaluation" (SMILE) was developed to fill out this gap. In this paper, we describe the development and the psychometric properties (internal consistency, concurrent and convergent validity) of a shorter version of the SMILE among university students. METHODSData from a cross-sectional study including 369 students from 10 Brazilian universities were used. Considering a theoretical nomological net, we performed exploratory factor analysis to obtain the most parsimonious, interpretable and good-fitting model. RESULTSThe final model was called U-SMILE, comprised 24 items, and presented acceptable internal consistency (Cronbach's α = 0.73, McDonald's ω = 0.79). To evaluate the concurrent validity of the U-SMILE, we compared it to the original SMILE and found a high correlation between the instruments (Spearman's r= 0.94). Furthermore, we evaluated convergent validity by examining the U-SMILE correlation with the PHQ-9 (Spearman's r= -0.517), and GAD-7 (Spearman's r= -0.356), two validated instruments to screen for depression and anxiety, respectively. DISCUSSIONOur findings suggest that the U-SMILE is a valid instrument for assessing lifestyle among university students. We recommend that the use of U-SMILE to evaluate overall lifestyle scores rather than individual domain scores. Finally, we discuss the importance of clarifying the definitions of lifestyle and related constructs in future research.
Sexually transmitted diseases (STD) are frequently asymptomatic and increase the likelihood of transmitting and acquiring HIV. In Brazil, the guidelines for STDs diagnosis and treatment are based on ...the syndromic approach. Nucleic acid amplification tests (NAAT) has been recommended as routine STDs screening in some countries, especially for men who have sex with men (MSM). Limited data are available about how to best define target groups for routine screening by NAATs within this population. We aimed to assess the prevalence of rectal and urethral Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections and syphilis, and the factors associated with having at least one STD among HIV-infected and uninfected MSM in Rio de Janeiro, Brazil.
From August 2010 to June 2012, 391 MSM were enrolled into the Evandro Chagas National Institute of Infectious Diseases-INI-Fiocruz cohort, and 292 MSM (HIV-infected:211 and HIV-uninfected:81) were included in this study. NAATs were performed on the rectal swabs and urine for CT and NG. The rapid plasma reagin test and microhemagglutination assay for Treponema pallidum were performed for syphilis diagnosis.
The overall prevalence of STD was 20.0% (95%CI:15.7-25.1): 10% anorectal chlamydia; syphilis 9.9%; anorectal gonorrheae 2.5%; and urethral chlamydia 2.2%; no case of urethral gonorrheae was detected. The proportion of HIV-positive MSM who had at least one STD was nearly two times that of HIV-negative MSM (22.6% vs 13.2%; P = 0.09). The frequency of each STD, except for anorectal NG (1.5% vs.5.2%), was higher among HIV-positive than HIV-negative individuals. Among the 211 asymptomatic participants, 17.5% (n = 37) were identified as having at least one STD; 10.4% (n = 22/211) tested positive for anorectal chlamydia. Sixty five percent of HIV-positive MSM were asymptomatic at the time of the STD diagnosis, while 100.0% of the HIV-negative MSM. Age (APR = 0.78; 95%CI:0.60-1.00 for each additional ten years) and a positive-HIV serostatus (APR = 2.05; 95%CI:1.03-4.08) were significantly associated with STD diagnosis.
An overall high STD-prevalence rate was observed, especially among HIV-infected and in younger individuals, and the majority of STDs were asymptomatic. STD screening using NAATs among asymptomatic MSM is a potentially cost-effective intervention for the prevention of HIV infection among MSM.

Highlights • Information from the medical chart did not allow the diagnosis of substance use disorders. • The medical chart was a more specific than sensitive indicator of lifetime substance use. • ...Concordance of medical chart and Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) substance use information varied by substance.
Self-rated health (SRH) is associated with morbidity and mortality in HIV-uninfected populations but is understudied in HIV. Substance use may affect SRH in addition to its deleterious effect on HIV ...disease. This analysis aimed to estimate SRH and substance use prevalence and evaluate factors associated with poor SRH among individuals in HIV care in Rio de Janeiro, Brazil. A convenience sample of HIV-infected adults completed one item of SRH, the Alcohol, Smoking and Substance Involvement Screening Test, and the Patient Health Questionnaire-2 (PHQ-2). Logistic regression models identified factors associated with poor SRH. Participants' (n = 1029) median age was 42.9 years, 64.2% were male, and 54.5% were nonwhite. Poor SRH was reported by 19.5% and the use of alcohol, tobacco, marijuana, and crack/cocaine by 30.1, 19.5, 3.9, and 3.5%, respectively. Less than high school education (adjusted odds ratio aOR 1.54, 95% confidence interval CI: 1.08-2.20), lack of sexual activity in previous 12 months (aOR 1.53, 95% CI: 1.01-2.30), crack/cocaine use (aOR 3.82, 95% CI: 1.80-8.09), positive PHQ-2 screen (aOR 3.43, 95% CI: 2.09-5.62), and HIV-1 RNA ≥40 c/ml (aOR 2.51, 95% CI: 1.57-4.02) were significantly associated with poor SRH as identified by logistic regression analyses. Alcohol, marijuana, and sedative use were not significantly associated with poor SRH. These results emphasize the need for substance use and mental health screening and treatment in this population. Further research may elucidate the consequences of poor SRH on treatment adherence, morbidity, and mortality in HIV-infected individuals.
