Occupational stressors and mental illness in healthcare work: An intersection between gender, race, and class.

Previous studies have supported the relevance of using broad and complex approaches, including multiple explanatory categories, to analyze mental disorders in the working population. This study aimed to assess the direct and indirect effects of gender, race, social class, and occupational stressors on mental health. A cross-sectional study used a random sample of 3343 health workers. The effort-reward imbalance (ERI) scale measured occupational stressors. The World Health Organization Self-Reporting Questionnaire (SRQ-20) evaluated common mental disorders (CMDs) as outcomes. The role of gender, race/color, and class determinants (level of schooling and income) in the relationship between occupational stressors and CMD was assessed. Structural equation modeling was used to determine associations and effects. Occupational stressors were directly associated with CMD and mediated the relationship between income and CMD. Gender was directly associated with occupational stressors, income, and domestic overload. Race was associated with education and with CMD through indirect paths mediated by class indicators. Class indicators contributed to increasing exposure to occupational stressors and the occurrence of CMD. The results highlight the relevance of gender, race/color, and class in understanding the unequal distribution of work stressors and mental illness in health workers.

Association between obesity and common mental disorders in women: a population-based study in Southern Brazil.

The study aimed to investigate the relationship between obesity and common mental disorders (CMD) among women. This is a cross-sectional population-based study with a representative sample of 981 adult women (20-60years of age) living in the urban area of the municipality of São Leopoldo, RS, Brazil, in 2015. The presence of CMD was assessed using the Self-Reporting Questionnaire (SRQ-20 ≥ 8). Obesity was defined by body mass index (BMI ≥ 30.0kg/m2). Prevalence ratios (PRs) for the association between obesity and CMD were measured by Poisson regression with robust variance, including their respective 95% confidence intervals (CIs). The mean age of the sample was 40.3years (standard deviation = 11.4years). The prevalence of CMD was 33.7% (95% CI 30.8-36.7), while obesity was 31.2% (95% CI 28.3-34.1). The occurrence of CMD was higher in women with low levels of education and belonging to lower economic class, as well as smokers and those who were insufficiently active. Obesity was more prevalent in older women (50-60years old) with less schooling, who did not consume alcohol, and those who were insufficiently active. After adjusting for potential confounding factors, women with obesity were 22% more likely to have CMD when compared to those without obesity (PR = 1.22; 95% CI 1.02-1.45; p = 0.030). This study demonstrated a significant association between obesity and the presence of CMD among women. Additionally, the prevalence of obesity and CMD were high in this population group.

Unpaid domestic work: persistence of gender-based labor division and mental disorders.

Evaluating characteristics of unpaid domestic work and its association with mental disorders, exploring gender differences. We analyzed cross-sectional data from the second wave of an urban population cohort (n = 2,841) aged 15 and older from a medium-sized city in Bahia (BA). The representative population sample was randomly selected in subsequent multiple steps. We interviewed the survey participants at their homes. This study analyzed sociodemographic, occupational, unpaid domestic work and mental illness data, stratified by sex (gender). We investigated the association between the work-family-personal time conflict, the effort-reward imbalance in domestic and family work and the occurrence of common mental disorders, such as generalized anxiety disorder and depression. We estimated prevalence, prevalence ratios and their respective 95% confidence intervals. Among the participants, the unpaid domestic activities were performed by 71.3% of men and 95.2% of women, who were responsible for the investigated activities, except for minor repairs. The percentages of paid work were higher among men (68.1% versus 47.2% among women). The distribution of stressors and conflict experiences showed an inverse situation between genders: men depicted the highest high percentage of low work-family-personal time conflict (39.0%), while among women, the highest percentage was of high conflict (40.0%); 45.8% of the men reported low effort-reward imbalance in domestic and family work, while only 28.8% of women reported low imbalance. The investigated mental disorders were more prevalent among women, who showed a significant association between work-family-personal time conflict and common mental disorders, as well as depression; among men, conflict was positively associated with common mental disorders. The effort-reward imbalance, in turn, was strongly related to CMD (Common Mental Disorders), generalized anxiety disorder and depression among women. Amid men, this discrepancy was only associated to depression. Domestic work persists as a mostly feminine assigned activity. The stressful situations of unpaid domestic work and the work-family-personal time conflict were more strongly associated with adverse effects on the female mental health.

Relationship between early weaning and common mental disorders in adolescents and adults: a literature review

The benefits of breastfeeding for the child and the mother are already well established in the literature. Recent studies indicate that the consequences of early weaning can affect not only childhood, but also adolescence and adulthood. Possible late consequences include an increased occurrence of long-term common mental disorders (CMD). However, there are few available data on this topic, which makes it necessary to carry out more research that seeks to evidence the association between breastfeeding and mental disorders. Therefore, this study aimed to carry out a literature review in order to relate early weaning with the occurrence of CMD. The search was carried out on the search portals PubMed, CENTRAL, SciELO and Lilacs. After searching with the descriptors, 3 articles were selected that matched the inclusion and exclusion criteria. The results indicate that prolonged breastfeeding has a protective effect on the mental health of adolescents and adults, being associated with lower risks of CMD occurrence.

The relationship between national cultural dimensions, maternal anxiety and depression, and national breastfeeding rates: An analysis of data from 122 countries

IntroductionBreastfeeding is a natural and universal practice across countries and cultures. It is estimated that several thousand lives could be saved per year if optimal breastfeeding practices were adopted across countries. In addition, breastfeeding has numerous health, emotional and developmental benefits for both the mother and her infant. Despite widespread awareness of these benefits, rates of breastfeeding initiation and maintenance remain suboptimal, both in high- and in low- and middle-income countries. Unfavorable breastfeeding outcomes are related to several factors, including variations in cultural values and the occurrence of common mental disorders in women during pregnancy and in the postnatal period. However, the relative contributions of culture and mental health to variations in national breastfeeding rates have not been examined to date.MethodsIn the current study, recent United Nations International Children's Emergency Fund (UNICEF) data on lifetime breastfeeding rates is analyzed in two stages, to first explore and then confirm the impact of cultural values and maternal mental health status at a cross-national level.ResultsIt was found that the estimated prevalence of both depression and anxiety disorders in women of childbearing age was negatively correlated with breastfeeding rates. Significant associations were also observed for the cultural dimensions of individualism-collectivism and masculinity-femininity. The association between anxiety disorders and breastfeeding outcomes remained significant in multivariate analysis incorporating demographic and health variables that could exert a confounding effect.DiscussionThese results suggest that both cultural values and the assessment and treatment of maternal mental illness should be components of any programme aimed at communicating the benefits of breastfeeding or at improving breastfeeding outcomes. The inclusion of these components could help promote the values of cultural sensitivity, inclusiveness and equity in breastfeeding from a global perspective.

Transtornos mentais comuns, produtividade e presenteísmo em trabalhadores de enfermagem

To investigate the association between the occurrence of common mental disorders with loss of productivity and presenteeism in nursing workers at a public health service. This is a cross-sectional study, with 291 workers from Midwestern Brazil. Data collection carried out from October 2019 to January 2020, with instruments for sociodemographic characterization, labor and health conditions: Self Reporting Questionnaire-20, Standford Presenteeism Scale and Work Limitations Questionnaire. Data were analyzed using descriptive and inferential statistics, with Mann-Whitney tests and logistic regression, respecting a significance level of 5%. The occurrence of common mental disorders was 4.27 times more likely to experience presenteeism, 10.17% of compromised overall productivity, and impairment of mental/interpersonal and production demands. The occurrence of common mental disorders was associated with presenteeism, with repercussions in loss of productivity of nursing workers.

Common mental disorders in pregnancy and postnatal depressive symptoms in the MINA-Brazil study: occurrence and associated factors.

ABSTRACTOBJECTIVE To investigate the occurrence and factors associated with common mental disorders in pregnancy and depressive symptoms in postpartum, as well as the association between both in the Brazilian Western Amazon.METHODS This is a prospective cohort in the MINA-Brazil study with women who received primary health care in the town of Cruzeiro do Sul, Acre State. We performed two clinical evaluations during pregnancy (the first: 16–20 weeks; the second: 28 gestational weeks) and three postpartum evaluations (at 3, 6 and 12 months), in which demographic and socioeconomic, gestational, lifestyle and clinical data were collected. We used the Self-Reported Questionnaire (score ≥ 8) to screen the gestational common mental disorder and the Edinburgh Postnatal Depression Scale (score ≥ 10) to identify postpartum depressive symptoms. We used adjusted ordinal logistic regression to investigate the relationship between the covariates and the occurrence of common mental disorders in pregnancy and postpartum depressive symptomatology.RESULTS A total of 461 women completed the two clinical evaluations in pregnancy; of these, 247 completed the three postpartum evaluations. The occurrence of common mental disorder during pregnancy was 36.2% and 24.5% in the first and second evaluations, respectively, and the cumulative incidence was 9.2%. In addition, 50.3% maintained the disorder between evaluations. During postpartum, approximately 20% of the mothers presented depressive symptoms during the first year of their children’s lives. Parity (≥ 2) was associated with common mental disorders, while low maternal education was associated with postpartum depressive symptoms. Women with a common mental disorder in both evaluations during pregnancy were 5.6 times more likely (95%CI: 2.50–12.60) to develop postpartum depressive symptoms.CONCLUSION The occurrence of common mental disorder at any time assessed during pregnancy, but especially its persistence from the second trimester, was strongly associated with depressive symptoms after childbirth. These findings highlight the need for early screening and monitoring of the mental health of pregnant women at the start of prenatal care in order to reduce possible negative impacts on the health of the mother-child binomial caused by such events.

Stressful work in primary health care and mental health: The role of gender inequities in Brazil.

This study aims to analyze the association between occupational stressors, evaluated by the Effort-Reward Imbalance Model (ERI), and the occurrence of common mental disorders (CMD) among healthcare workers (HCW), additionally considering mediation by over-commitment from work (OW) and mediation of gender effects by work stressors. Cross-sectional study, including a random sample of 3343 HCWs, from six municipalities of Bahia, Brazil. The ERI scale measured the occupational stressors (main exposure), and the Self-Reporting Questionnaire (SRQ-20) was used to screen for CMD. Data analysis used Structural Equation Modeling techniques to understand the relationships between gender, occupational stressors, and the occurrence of CMD. ERI and OW were associated with CMD. OW mediated the negative effect of ERI on the mental health of HCW. Female workers had higher levels of ERI, OW, and CMD prevalence; the total gender effect on CMD prevalence was mediated by ERI and OW. The findings highlight the association of work psychosocial stressors and CMD among HCW, including partial mediation by OW. Gender inequalities persisted among HCW, with women most exposed to occupational stressors and CMD. ERI and OW partially mediated the effect of gender on CMD.

The relationship between protective factors and common mental disorders among female urban slum dwellers in Ibadan, Nigeria.

BackgroundOn the African continent, many people live in conditions of adversity known to be associated with the onset of mental disorders, yet not all develop a mental disorder. The prevalence of common mental disorders such as depression and anxiety in the general population of Nigeria is comparatively low. Prevalence data of mental disorders in slum settings in Nigeria is sparse. There is a need to better understand the relationship between protective factors and the occurrence of common mental disorders in the Nigerian slum context. This study aimed to describe the relationship between protective factors and the occurrence of common mental disorders among female urban slum dwellers in Ibadan, Nigeria.Methods and findingsA cross sectional household survey of 550 women was conducted in slum settlements in Ibadan, Nigeria. Interviewer administered questionnaires were completed to elicit information on protective factors (social connectedness, self-esteem, social support, resilience) and common mental disorders (depression, anxiety and stress). The DASS-21 was used to measure common mental disorders and protective factors were measured using the Social Connectedness Scale, Multidimensional Scale of Perceived Social Support, Resilience scale and the Rosenberg Self Esteem Scale. A multivariable logistic regression model was employed to examine associations while adjusting for relevant confounders. Common mental disorders were reported by 14.0% of the respondents. Resilience and social support were found to be protective against reporting symptoms of common mental disorders. Women who reported higher levels of social support and resilience were less likely to report common mental disorders (OR:0.96, 95% CI 0.93, 0.98) and (OR:0.95, 95% CI 0.91, 0.99) respectively. Women who were 65 years and older were also less likely to report the occurrence of common mental disorders (OR:0.38, 95% CI 0.15, 0.98) compared to those aged 18–34 years.ConclusionSocial support and resilience appear to be protective against common mental disorders among these respondents. Further research should be conducted to explore the pathways through which protective factors reduce the likelihood of the occurrence of common mental disorders. This would be important in the development of mental health interventions.

Occupational stress and common mental disorders: how do coping strategies work?

IntroductionCoping strategies are described as devices capable of minimizing the effects of occupational stress on workers’ mental health.ObjectivesTo evaluate the association between occupational stressors and occurrence of common mental disorders and how coping strategies work in this relationship.MethodsThis is a cross-sectional study with 3,343 healthcare workers from six municipalities in the state of Bahia, Brazil. Common mental disorders were measured by the Self-Reporting Questionnaire, and occupational stressors by the Job Content Questionnaire. Coping strategies included physical activity, leisure activities, social support at work, alcohol consumption, and smoking. Bivariate and multivariate analyses were performed, stratified by sex.ResultsOccupational stressors were associated with common mental disorders, more strongly among women. The practice of physical activity contributed to reduce the prevalence of common mental disorders, regardless of occupational stressors. Leisure activities were associated with lower prevalence of common mental disorders, but without statistical significance, losing relevance in the presence of occupational stressors. Social support and smoking or drinking habits were not associated with common mental disorders and did not influence the relationship with occupational stressors.ConclusionsOccupational stressors are associated with common mental disorders, with emphasis on high demand, even after adjusted for coping strategies. The relationship between occupational stressors and mental is corroborated, with greater female vulnerability, as well as the role of positive coping strategies in protecting mental health. The pertinence of adopting measures that reduce stress at work, promote the adoption of positive coping strategies, and consider gender inequalities in these relationships.

Psychological Distress in Men during the COVID-19 Pandemic in Brazil: The Role of the Sociodemographic Variables, Uncertainty, and Social Support.

Objective: To analyze the relationships between sociodemographic variables, intolerance to uncertainty (INT), social support, and psychological distress (i.e., indicators of Common Mental Disorders (CMDs) and perceived stress (PS)) in Brazilian men during the COVID-19 pandemic. Methods: A cross-sectional study with national coverage, of the web survey type, and conducted with 1006 Brazilian men during the period of social circulation restriction imposed by the health authorities in Brazil for suppression of the coronavirus and control of the pandemic. Structural equation modeling analysis was performed. Results: Statistically significant direct effects of race/skin color (λ = 0.268; p-value < 0.001), socioeconomic status (SES) (λ = 0.306; p-value < 0.001), household composition (λ = 0.281; p-value < 0.001), PS (λ = 0.513; p-value < 0.001), and INT (λ = 0.421; p-value < 0.001) were evidenced in the occurrence of CMDs. Black-skinned men with higher SES, living alone, and with higher PS and INT levels presented higher prevalence values of CMDs. Conclusions: High levels of PS and INT were the factors that presented the strongest associations with the occurrence of CMDs among the men. It is necessary to implement actions to reduce the stress-generating sources as well as to promote an increase in resilience and the development of intrinsic reinforcements to deal with uncertain threats.

Lifestyle patterns associated with common mental disorders in Brazilian adolescents: Results of the Study of Cardiovascular Risks in Adolescents (ERICA).

The association between lifestyle factors and mental health has been evaluated in isolation; however, there has been a lack of information about lifestyle patterns and Common Mental Disorders (CMD) in adolescents. Therefore, the present study aims to assess the association between sets of lifestyle patterns and the occurrence of CMD in Brazilian adolescents evaluated in a national school-based cross-sectional survey. The outcome variable considered was presence of CMD. Lifestyle patterns were identified from the Principal Component Analysis. Consumption of foods, water and alcoholic beverages, sleep, physical activity, and smoking were used to identify patterns as explanatory variables. Sociodemographic characteristics, administrative dependence of the school and, nutritional status, were considered adjustment factors in the regression model. A total of 70,427 adolescents were evaluated. The principal component analysis identified three lifestyle patterns: high consumption of ultra-processed foods and low consumption of unprocessed or minimally processed foods (pattern 1); high consumption of alcoholic beverages and tobacco in the last 30 days (pattern 2); and high consumption of water and high level of physical activity (pattern 3). In the adjusted model, in patterns 1 and 2, the third tertile presented greater chance of CMD (OR 1.68; CI 95% 1.51–1.87 and OR 1.38; CI 95% 1.19–1.60, respectively). In pattern 3, the second (OR 0.88; CI 95% 0.80–0.96) and the third (OR 0.80; CI 95% 0.72–0.88) tertiles presented lower chances of CMD among the adolescents evaluated. Therefore, we suggest that health-promoting practices aimed at adolescents include multiple behaviors, with the objective of ensuring physical, mental, and social well-being.

Context, design and conduct of the longitudinal COVID-19 psychological research consortium study-wave 3.

ObjectivesThe COVID‐19 Psychological Research Consortium (C19PRC) Study aims to assess the impact of the COVID‐19 pandemic in the adult population in multiple countries. This paper describes the third wave of the UK survey (the ‘parent’ strand of the Consortium) during July‐August 2020.MethodsAdults (N = 2025) who participated in the baseline and/or first follow‐up surveys were reinvited to participate in this survey, which assessed: (1) COVID‐19 related knowledge, attitudes, and behaviours; (2) the occurrence of common mental disorders; as well as the role of (3) psychological factors and (4) social and political attitudes, in influencing the public’s response to the pandemic. Weights were calculated using a survey raking algorithm to ensure that the cross‐sectional sample is nationally representative in terms of gender, age, and household income, and representative of the baseline sample characteristics for household composition, ethnicity, urbanicity and born/raised in UK.Results1166 adults (57.6% of baseline participants) provided full interviews at Wave 3. The raking procedure successfully re‐balanced the cross‐sectional sample to within 1% of population estimates across selected socio‐demographic characteristics.ConclusionThis paper demonstrates the strength of the C19PRC Study data to facilitate and stimulate interdisciplinary research addressing important public health questions relating to the COVID‐19 pandemic.

Inatividade física no lazer e transtornos mentais comuns em trabalhadores da Atenção Primária à Saúde

Objetivo: Avaliar a associação entre inatividade física no lazer (IFL) e transtornos mentais comuns (TMC) entre trabalhadores(as) da Atenção Primária à Saúde (APS). Métodos: Estudo transversal, realizado com amostra aleatória de 2.136 trabalhadores(as) da APS de municípios do estado da Bahia. O questionário de coleta de dados incluiu características sociodemográficas e ocupacionais, hábitos de vida e o Self-Reporting Questionnaire. Procedeu-se análise multivariada, com uso da Regressão de Poisson com variância robusta. Resultados: Identificaram-se prevalências de 22,6% para TMC e 48,2% para IFL. Na análise bivariada, houve maior prevalência de TMC naqueles com IFL (p&lt;0,001), sexo feminino (p=0,015), menor nível de escolaridade (p=0,001) e renda (p&lt;0,001), nos Agentes Comunitários de Saúde (p&lt;0,001), com tempo de trabalho de cinco anos ou mais (p=0,040) e com comportamento sedentário no lazer (assistir TV e/ou ouvir rádio) (p=0,025). Evidenciou-se incremento da prevalência de TMC entre aqueles com IFL (53%), com tempo de trabalho na unidade maior ou igual a cinco anos (20%) e cujas atividades no seu tempo de lazer eram assistir TV e ouvir rádio (30%). Na análise múltipla, a associação entre IFL e TMC manteve-se significante (RP: 1,36; IC95%: 1,11-1,65), ajustando-se pelas variáveis confundidoras. Conclusão: A IFL é importante fator determinante da ocorrência de TMC entre trabalhadores(as) da APS, com influência de características da organização e processo de trabalho e outros hábitos de vida no lazer nessa relação.

The role of family meal frequency in common mental disorders in children and adolescents over eight months of follow-up.

ObjectiveThis study evaluated the influence of family meal frequency on the occurrence of common mental disorders (CMD) in children and adolescents over eight months of follow-up.DesignData from this longitudinal study were derived from the PAAPAS—Parents, Students, Community Health Agents, and Teachers for Healthy Eating—community trial. CMD were evaluated using the General Health Questionnaire. Frequency of family meals (breakfast and dinner) was categorized as “breakfast and dinner regularly with the family”, “at least breakfast or dinner regularly with the family”, and “does not have any meal regularly with the family.” The effect of family meal frequency on CMD was analyzed using generalized estimation equations with log-binomial models for repeated measures.SettingThis study was conducted in public schools (N = 18) of Duque de Caxias, Rio de Janeiro, Brazil, in 2016.ParticipantsChildren (aged 9–11 years) and adolescents (aged 12–17 years) from the fifth and sixth grades (N = 2,743).ResultsThese findings suggested that regular family meals were a protective factor for mental health. The adjusted relative risk of CMD was 0.75 (95% confidence interval = 0.69–0.83) for those who had two family meals regularly and 0.87 (95% confidence interval = 0.77–0.97) for those who had only one regular family meal, compared to students who had no regular family meals.ConclusionsPotential strategies that educate and encourage families about the mental health benefits of eating regular meals together must be explored and implemented.

Mudik during the Covid-19 pandemic, anxiety, and depression among students in Indonesia

Purpose: This study explores the occurrence and different levels of anxiety and depression among male and female students who perform or do not perform mudik (homecoming). Investigate the primary source of COVID-19 related information among students. Methods: Online questionnaires consisting of the self-report level of anxiety and depression were delivered to study participants after completing the online informed consent. Quantitative analysis was conducted using the IBM SPSS version 20.0.Results: From a total of 2018 study participants, n=936 were students. Depression (M=8.68; SD= 5.45) was higher among students who did not perform mudik. Meanwhile, the prevalence rate of depression (M=7.18; SD=4.99) was also higher among students who performed mudik. A significant difference [sig (2-tailed) = 0.017; p &lt;0.05)] regarding the level of anxiety was reported higher among female students (M=7.80; SD=4.6) than male students (M=7.03; SD=4.7) and no significant difference [sig (2-tailed) = 0.173; p&gt; 0.05] was reported for the level of depression between male and female students. Instagram was reported as the primary source of COVID-19 related information. Conclusion: This current study supports the notion regarding the occurrence of common mental disorders among students as an impact of the COVID-19 pandemic, regardless of whether homecoming was performed or not. Different levels of anxiety and depression were reported between the male and female student population.

Transtornos mentais comuns e fatores associados entre pessoas com hanseníase: análise transversal em Cuiabá, 2018 *

To analyze the occurrence of common mental disorders (CMDs) and associated factors in people with leprosy with complications in the state of Mato Grosso, Brazil, in 2018. This was a cross-sectional study with people attending Júlio Müller University Hospital. The Self-Report-Questionnaire (SRQ-20) was used. Poisson regression analysis was performed to estimate prevalence ratios (PR) and 95% confidence intervals (95%CI). Among 206 people with leprosy, CMDs were found in 70.4% (95%CI 61.10;76.67) and were associated with the female sex (PR=1.29 - 95%CI 1.09;1.53), the 26-45 age range (PR=1.52 - 95%CI 1.09;2.11) and the 46-60 age range (PR=1.40 - 95%CI 1.01;1.95), low family income (PR=1.25 - 95%CI 1.05;1.49), and unsatisfactory quality of life in the physical domain (PR=3.03 - 95%CI 1.12;8.19) and the psychological domain (PR=1.91; 95%CI 1.40;2.61). CMDs were frequent and associated with female sex, productive age group, low income and unsatisfactory quality of life. Actions aimed at mental health in this population group are necessary.

Is living near green areas beneficial to mental health? Results of the Pró-Saúde Study.

ABSTRACTOBJECTIVE To investigate the association between exposure to green areas in the surroundings of the residence and the presence of common mental disorders among adults, according to different income strata.METHODS Cross-sectional study with 2,584 participants from the Pró-Saúde Study (2006), residing in the city of Rio de Janeiro. Common Mental Disorders were measured using the General Health Questionnaire (GHQ-12) and exposure to green areas was measured using the normalized difference vegetation index, in buffers with radiuses between 100 and 1,500 meters around the residence. We used the mean and maximum normalized difference vegetation index categorized into quartiles. The study population was divided into three subgroups, according to the income: low, intermediate, and high. Odds ratios and their 95% confidence intervals were estimated with logistic regression models. The models were adjusted by sex and age, with and without inclusion of physical activity practice.RESULTS The proportion of common mental disorders was 30% and 39% among men and women, respectively. The results of the adjusted models showed an inverse association between the presence of green areas in the surroundings of the residence and the occurrence of common mental disorders, in the buffer of 200 meters in the intermediate-income group and in the buffers of 400 and 1,500 meters in the low-income group. The odds ratio ranged from 0.52 (buffer of 1,500 meters) to 0.68 (buffer of 200 meters). The association found was independent of physical activity practice.CONCLUSIONS The evidence found suggests the existence of a beneficial effect of urban green areas on the mental health of lower-income individuals. These findings can help in understanding how the urban environment can affect the mental health of the population.

Exposure to breastfeeding and common mental disorders in adolescence

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.
