Factors influencing the work of researchers in Scientific Initiation: A systematic review protocol.

INTRODUCTION: Scientific Initiation (SI) is an educational activity that allows students to begin their scientific training and research under the guidance of an experienced researcher. While several studies have examined students' perceptions of SI, research on the perspective of researchers working in this field is currently lacking. Thus, this study's aim is to describe the protocol design for conducting a systematic review. At the same time, the review aims also to identify factors influencing the work of researchers in SI and explore the motivations leading researchers to engage in research projects within institutions and their respective impacts. METHOD AND ANALYSES: Literature search will be done using the bibliographic databases, including Academic Search Premier, APA PsycNet, CINAHL Plus, ERIC, SocINDEX, Scopus, and Web of Science. The search strategy was guided by the PICo framework (Population, phenomenon of Interest, and Context). The preparation and development of this protocol following guidelines were employed: Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Protocols 2015 (PRISMA-P 2015), Peer Review of Electronic Search Strategies 2015 (PRESS 2015), and PRISMA-Search (PRISMA-S). Original, peer-reviewed articles that examine the factors related to the work of researchers in SI will be included without any language or publication date restrictions. Qualitative, quantitative, and mixed-methods studies will be screened by two independent researchers. The included studies will be analyzed to identify factors, policies, and their impacts obtained analytically. Findings will be objectively categorized and synthetically represented through figures, diagrams, and graphic models. The risk of bias will be assessed using the Critical Appraisal Skills Program (CASP) and the Downs and Black checklists. A third senior reviewer will resolve any discrepancies. DISCUSSION: We aim to understand the factors that drive researchers to engage in SI research through the dissemination of the findings of this systematic review. This may aid the development of institutional strategies and actions that can support the enhancement of SI programs and encourage greater researcher participation.

Indicators of Eating Disorders in Sexually Abused Brazilian Adolescents: Family and School Contexts.

Eating disorders, characterized by abnormal eating behaviors, are among a wide variety of psychiatric conditions that mainly affect children and adolescents. These disorders have a multifactorial origin and can be associated with restrictive diets, negative feelings, harmful family relationships, and post-traumatic stress. Thus, this study's objective was to evaluate the association between indicators of eating disorders and family and school contexts in Brazilian adolescents who previously experienced sexual abuse and examine the findings based on sex. National School Health Survey data were utilized. Among 102,301 students between 11 and 19 years of age, 4124 reported having experienced sexual abuse and were included in this study. Self-report questionnaires were used to assess participants' health status and the presence of risk behaviors, which were examined through multivariate analysis using a Poisson regression model. The results indicated positive relationships between self-induced vomiting, laxative misuse, and other purgative methods and infrequent meals with family, hunger, and the presence of violence in students' daily lives, regardless of sex (p < 0.05). In addition, body dissatisfaction and negative feelings about one's body were associated with having been bullied or teased by schoolmates for both sexes (p < 0.05). Distant relationships with parents were associated with purgative methods and body dissatisfaction among female students (p < 0.05). In conclusion, body dissatisfaction, negative feelings about one's body, laxative misuse, self-induced vomiting, and purgative methods were found to be associated with factors in family and school contexts such as hunger, infrequent meals with family, family violence, distant relationships with parents, and bullying at school in adolescents who have previously experienced sexual abuse.

Administrative professionals' quality of life in educational institutions: a systematic review protocol.

INTRODUCTION: Indicators of administrative professionals' quality of life (QoL) in educational institutions are essential for planning improvements in their daily lives. QoL is a recurring topic in academic research, particularly in the healthcare sector. Therefore, this study aims to evaluate the perceptions of administrative professionals in educational institutions regarding their QoL and the implications of remote and in-person work. Additionally, we aim to compare the QoL before, during and after the COVID-19 pandemic. METHODS AND ANALYSIS: Five electronic databases will be searched for this systematic review: CINAHL, LILACS, PubMed, Scopus and Web of Science. Original, peer-reviewed articles published in any language, without time limitations, will be included in this study. Two researchers will screen the articles and extract the data. The included articles will be evaluated for the quality of their evidence using Grading of Recommendations, Assessment, Development and Evaluations. The risk of bias will be assessed using the Critical Appraisal Skills Programme checklist and the Downs and Black scale. A third reviewer will resolve any discrepancies. ETHICS AND DISSEMINATION: The systematic review results will be published in a peer-reviewed journal and presented at a relevant conference. The data will not include individual patient data; therefore, ethical approval is not required. PROSPERO REGISTRATION NUMBER: CRD42022365862.

Changes in Food Consumption in Postmenopausal Women during the COVID-19 Pandemic: A Longitudinal Study.

Studying the dietary habits and symptoms of postmenopausal women during situations such as the COVID-19 pandemic is important to mitigate long-term post-pandemic health problems. We compared the menopausal symptoms and food consumption in postmenopausal women before and during the COVID-19 pandemic. A longitudinal survey was conducted on postmenopausal Brazilian women between 2018 and 2021. The Kupperman-Blatt Menopausal Index, Women's Health Questionnaire, and 24 h food recall were used. Of 274 women, 78 (28.5%) participated in the study during the COVID-19 pandemic. The intensity of the symptoms was lower during the pandemic than during the previous period (p < 0.05). Energy and processed food consumption were lower during the pandemic than before (p = 0.003 and p = 0.003, respectively). Milk and plain yogurt consumption were also lower (p = 0.043), while the consumption of sugar-sweetened beverages and sweet foods was higher (p = 0.007 and p = 0.001, respectively) during the pandemic. There was also a decrease in the consumption of proteins and lipids (p = 0.001 and p = 0.004, respectively). In conclusion, we found that postmenopausal women consumed sweet foods and sugar-sweetened beverages in higher quantities and had a lower consumption of milk and plain yogurt and processed foods during the pandemic than during the pre-pandemic period. Furthermore, decreases in energy and macronutrient consumption were observed.

Interventions towards barriers to the practice of physical activity in adolescence: A systematic review protocol.

INTRODUCTION: Lack of regular physical activity is recognized as a global public health issue. Three out of every four adolescents do not adhere to physical activity recommendations. Thus, this systematic review will evaluate interventions employed to minimize barriers to physical activity among adolescents. Herein, we present the study protocol. To the best of our knowledge, this will be the first systematic review to assess the interventions implemented to minimize barriers to the practice of physical activity among adolescents. A systematic understanding of the most effective interventions to reduce the barriers to physical activity is essential. METHOD AND ANALYSIS: We will search five databases: two multidisciplinary (Scopus and Web of Science) and three other health-related databases (Embase, SPORTDiscus, and PubMed). The search will be limited to original peer-reviewed articles published in English, with no time restrictions. The search strategy will use MeSH terms and their variations to maximize the search strategy. Two reviewers will independently read the included articles, extract the data, and evaluate the methodological quality using the Grading of Recommendations, Assessment, Development, and Evaluation scale and the risk of bias using the Critical Appraisal Skills Programme checklist and Downs and Black scale. Discrepancies will be resolved by a third reviewer. This systematic review will follow the guidelines outlined in the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses. DISCUSSION: The outcomes of this study are expected to enhance the current understanding of the obstacles to physical activity among adolescents and aid in the development or modification of programs to combat physical inactivity in this population. Consequently, these findings should have a positive impact on current and future adolescent health outcomes. ETHICS AND DISCLOSURE: Ethical approval will not be required for this study as it is an analysis of previously published articles (i.e., secondary data). The results will be published in a peer-reviewed journal. PROSPERO registration: CRD42022382174.

Relationship between depression and quality of life among students: a systematic review and meta-analysis.

The objectives of this systematic review were to estimate the prevalence of depression and to identify the relationship between depression and quality of life (QOL) among high school and university students. Literature search was performed in the Scopus, Embase, PubMed, Scielo, CINAHL and Web of Science databases, following the PRISMA methodology. The results were presented through descriptive approaches and meta-analysis. Thirty-six studies met the eligibility criteria, and twenty-six were included in the meta-analysis. The prevalence of depressive symptoms was 27% (95% CI 0.21-0.33) among students, being high school and university students was 25% (95% CI 0.14-0.37) and 27% (95% CI 0.20-0.34), respectively, and most studies have shown that depression was associated with low QOL. Among the limitations of the study is the difficulty of generalizing the results found, considering the large sample of health students. New studies should be conducted considering the severity, duration, and patterns of depressive symptoms in high school and university students, to better understand the relationship between depression and QOL.

Physical Activity and Sedentary Behavior in High School Students: A Quasi Experimental Study via Smartphone during the COVID-19 Pandemic.

The objective of this study was to evaluate whether exposure to information about physical activity and its barriers can increase the level of physical activity and reduce the time exposed to sedentary behaviors in high school students involved in integrated professional and technological education during the coronavirus disease 2019 pandemic. This quasi experimental study was conducted with integrated education high school students, divided into two groups: Intervention Group (IG; n = 59) and Control Group (CG; n = 54). Physical activity and sedentary behavior were identified and measured using the International Physical Activity Questionnaire pre-and post-intervention for both groups. IG students received educational material thrice a week for four weeks. The focus of the material was the importance of physical activity and need to reduce the time exposed to sedentary behavior. The results revealed that IG students showed an average daily reduction of 47.14 min in time exposed to sedentary behaviors, while the CG students showed an increase of 31.37 min. Despite this, the intervention was not effective in improving physical activity levels in the IG and the mean reduction in the time exposed to sedentary behavior was not significant (p = 0.556). The intervention was ineffective in increasing the practice of physical activity and reducing the time exposed to sedentary behavior.

Prevalence of Vitamin D and Calcium Deficiency and Insufficiency in Women of Childbearing Age and Associated Risk Factors: A Systematic Review and Meta-Analysis.

Vitamin D deficiency and insufficiency as well as low serum calcium levels can trigger negative health outcomes in women of childbearing age. Therefore, we aimed to estimate the prevalence of serum vitamin D and calcium deficiencies and insufficiencies and associated risk factors in Brazilian women of childbearing age and to assess whether there are differences in prevalence according to regions of the country and the presence or absence of pregnancy. The systematic literature review was performed using the following databases: PubMed, LILACS, Embase, Scopus, and Web of Science. Cross-sectional, cohort, and intervention studies were included. Among pregnant women, the prevalence of vitamin D deficiency ranged from 0% to 27% and of vitamin D insufficiency from 33.9% to 70.4%. Among non-pregnant women, the prevalence of vitamin D deficiency ranged from 0% to 41.7% and of vitamin D insufficiency from 38.5% to 69.3%. We found a high prevalence of vitamin D deficiency and insufficiency in women of childbearing age, with insufficiency affecting more than half of these women. The highest prevalence of vitamin D deficiency and insufficiency was observed in the South region. It was not possible to assess the prevalence and factors associated with calcium deficiency.

Tools for Assessing Knowledge of Back Health in Adolescents: A Systematic Review Protocol.

Back pain is common in adolescents as a result of their typical daily activities. There is a critical need for developing instruments that can assess the adolescents' knowledge of proper posture, because adequate postural habits are essential for preventing back pain and facilitating physical well-being. Unfortunately, there is insufficient understanding about appropriate back health in the general public, even though this knowledge is decisive in the development of physical skills and attainment of health literacy. Furthermore, relevant substantive literature is scarce. Therefore, the proposed systematic review aims to identify instruments that are used for assessing knowledge of back health in adolescents. Relevant search terms and descriptors will be combined, and searches will be carried out in a uniform sequence within the PubMed, Embase, CINAHL, and Cochrane Library databases. Eligible articles must present data on the assessment of the adolescents' knowledge of back health and describe the applied instrumentation. Articles will be selected by two reviewers independently; all disagreements will be resolved by a third reviewer. Mendeley and the Rayyan software will be used for the systematic review, and the checklist proposed by Brink and Louw will be used to verify the methodological quality of the included studies. Our findings may confirm the relevance of constructing and validating back health instruments for use in Brazil and other countries.

Prevalence of vitamin D and calcium deficiencies and their health impacts on women of childbearing age: a protocol for systematic review and meta-analysis.

INTRODUCTION: No systematic reviews has synthesised data on the available evidence to determine the prevalence of calcium and vitamin D deficiencies as a public health problem globally. Therefore, this study presents a protocol for conducting a review and meta-analysis to estimate the prevalence of calcium and vitamin D serum deficiencies in women of childbearing age and stratify these data by age group, urban and rural area, world region and pregnant/non-pregnant women whenever possible. METHODS AND ANALYSIS: The systematic review protocol involves conducting a literature search in the following databases: PubMed, LILACS, Embase, Scopus and Web of Science. The selected articles will be checked thoroughly, including the references to include grey literature. Cross-sectional studies and baseline data from cohort studies or clinical and community trials conducted with women of childbearing age with representative probabilistic sampling will be included. Two independent researchers will be responsible for article selection and data extraction, and discrepancies, if any, will be dealt with by a third reviewer. Methodological quality and risk of bias will be analysed using the Grading of Recommendations, Assessment, Development and Evaluations and Joanna Briggs Institute's checklist, respectively. The heterogeneity of the estimates between studies will also be evaluated. Dissemination of the key findings from the systematic review will help identify priorities for action, establish dietary guidelines, develop health-related public policies and reduce and combat micronutrient deficiencies among women of childbearing age and their children. ETHICS AND DISSEMINATION: Formal ethical approval is not required, and findings will be published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42020207850.

Barriers to high school and university students' physical activity: A systematic review.

Physical inactivity commonly occurs throughout one's life, particularly during adolescence and young adulthood. Multiple factors can negatively influence participation in physical activity, but there has been no review examining the barriers to physical activity among high school and university students. Therefore, the aim of this systematic review was to summarize evidence of barriers to the practice of physical activity among high school and university students. The literature search was conducted without time limits using five databases, including CINAHL, Cochrane Library, Embase, PubMed, and Scopus. In total, 59 studies (37 with high school students [n = 22,908] and 22 with university students [n = 15,411]) were included. The main barriers identified in high school and university students were lack of time, lack of motivation, and lack of accessible places. These findings may be useful in designing and implementing evidence-informed interventions and programs for physical activity promotion in students.

Depressive Symptoms and Their Associated Factors in Vocational-Technical School Students during the COVID-19 Pandemic.

The objectives of this study were to compare the prevalence of depressive symptoms, behavioral habits, and QoL in students from two vocational-technical schools, and to determine the association of depressive symptoms with behavioral habits and quality of life (QoL) in these students during the COVID-19 pandemic. A cross-sectional survey was conducted with students attending the institution of the Brazilian Federal Network of Professional, Scientific and Technological Education. The students answered a questionnaire on sociodemographic variables, situations related to the COVID-19 pandemic, behavioral habits, QoL, and depressive symptoms. The outcome variable was the presence of depressive symptoms, assessed using the Children's Depression Inventory (CDI). Poisson regression analysis with robust variance was performed. A total of 343 students participated in this study (women, 55.7%; mean age of 16.1 ± 0.93 years). The prevalence of depressive symptoms among students was 43.4% (95% confidence interval [CI]: 38.0-49.0), and these symptoms were significantly associated with being female (prevalence ratio [PR] 1.72; 95% CI: 1.31-2.27); being in the 10th grade (PR: 1.80; 95% CI: 1.18-2.76) and 9th grade (PR 2.08; 95% CI: 1.37-3.18); social isolation (PR: 2.04; 95% CI: 1.00-4.14); hunger due to a lack of food at home (PR: 1.78; 95% CI: 1.33-2.39); low physical activity levels (PR: 1.68; 95% CI: 1.09-2.59); and moderate (PR: 2.87, 95% CI: 1.68-4.89) and low QoL (PR: 5.66; 95% CI: 3.48-9.19). The results emphasize the importance of interventions aimed mainly at female students and those in the initial years of high school, in addition to the importance of physical activity, food safety, and QoL to improve the mental health of students.

Life habits of postmenopausal women: Association of menopause symptom intensity and food consumption by degree of food processing.

OBJECTIVE: To evaluate in postmenopausal women the association between menopause symptom intensity and the quality of life and clinical, anthropometric, and lifestyle factors, focusing on food consumption by degree of processing. STUDY DESIGN: A cross-sectional study of 288 postmenopausal women using interviews. MAIN OUTCOME MEASURES: The Kupperman-Blatt Menopausal Index and the Women's Health Questionnaire were used to evaluate the main outcomes of menopausal symptom intensity and quality of life, respectively. Data on socioeconomic, clinical, anthropometric, and lifestyle variables (smoking, alcohol intake, physical activity, and food consumption) were collected. RESULTS: Most women had moderate to severe intensity of menopausal symptoms. The highest tertile of ultra-processed food consumption was associated with a greater intensity of vasomotor symptoms (prevalence ratio [PR] 0.73, 95% confidence intervals [CI] 0.55-0.96) and sexual behavior (PR 1.22, CI 1.01-1.49). Higher intakes of sugar-sweetened beverages and sausages were associated with somatic symptoms (PR 1.23, CI 1.01-1.49) and poorer memory/concentration (PR 1.22, CI 1.02-1.47/ PR 1.22, CI 1.01-1.48). The highest tertile of vegetable intake was associated with greater protection against depressive mood (PR 0.64, CI 0.43-0.96), vasomotor symptoms (PR 0.79, CI 0.63-0, 99), and sleep disorders (PR 0.83, CI 0.69-0.99), and better quality of life (PR 0.79, CI 0.62-0.99). CONCLUSION: More intense vasomotor, sexual, somatic, and memory and concentration symptoms are associated with a higher consumption of ultra-processed foods, whereas those with a higher consumption of vegetables reported lower menopause symptom intensity and a better quality of life.

The contexts of science journalism in the Brazilian Federal Institutes: characterizing realities and possibilities of communication products.

A public teaching and research institution can also be recognized for its scientific projection in society, as well as for interfering directly or indirectly in social dynamics through science. In this sense, this study intends to analyze how science communication is inserted in the communication of Federal Institutes of Brazil, characterizing the contexts in which science journalism develops in these places and the possibilities of products for publicizing science. To this end, we conducted a case study with a mixed approach - qualitative and quantitative methods. Interviews were directed to communication managers (n = 2), research managers (n = 5), and research dean (n = 2). We also applied a questionnaire to journalists and communicators (n = 23), research managers (n = 11), student researchers (n = 52), and researcher supervisors (n = 156). The interviews were recorded, transcribed, and analyzed through thematic analysis. We also use inferential statistics for the questionnaires to compare the opinions and assessments of the groups, contextualizing the dissemination of science, as well as drawing perspectives for improvements and the creation of communication products. The main findings indicate that, for science journalism to develop, it is necessary to a) establish guidelines for the dissemination of science, b) recognize and prioritize research publications, c) plan the work of science journalism and create routines, d) improve communication flow, and e) create journalistic products and processes. From these actions, it may be possible improve communication between Brazilian Federal Institutes and society through science.

Which Diets Are Effective in Reducing Cardiovascular and Cancer Risk in Women with Obesity? An Integrative Review.

Women are more affected by obesity than men which increases their risk of cancer and cardiovascular disease (CVD). Therefore, it is important to understand the effectiveness of different types of diet in the context of women's health. This review aims to summarize the scientific evidence on the effects of different types of diet for women with obesity and their impact on CVD and cancer risk. This review included epidemiological and clinical studies on adult women and different types of diets, such as the Mediterranean (MED) diet, the Traditional Brazilian Diet, the Dietary Approach to Stop Hypertension (DASH), intermittent fasting (IF), calorie (energy) restriction, food re-education, low-carbohydrate diet (LCD) and a very low-carbohydrate diet (VLCD). Our main findings showed that although LCDs, VLCD and IF are difficult to adhere to over an extended period, they can be good options for achieving improvements in body weight and cardiometabolic parameters. MED, DASH and the Traditional Brazilian Diet are based on natural foods and reduced processed foods. These diets have been associated with better women's health outcomes, including lower risk of CVD and cancer and the prevention and treatment of obesity.

Perceptions, relationships, expectations, and challenges: Views of communication and research for scientific dissemination in Brazilian Federal Institutes.

Communicating Brazilian science still seems to be a challenge for journalists and researchers of public institutions of education and science. In this sense, this research aims to identify and analyze scientists' perceptions regarding the work of journalists, the relationship between these groups, the expectations, and the challenges of science communication in two Federal Institutes of Education in Brazil. We conducted a mixed study in the qualitative stage with the participation of 30 interviewees, and in the quantitative stage, journalists and researchers answered a questionnaire (n = 242). Our results indicated that the work of science communication is not carried out properly in both Institutes and that there is a lack of articulated work among both journalists, communicators, and researchers. The relationship between these groups needs to be built jointly. In this respect, the biggest challenges are to institutionalize science communication, establish a science communication plan, and overcome internal relationship barriers. Our results may underpin science communication policies and policies for scientific dissemination both institutional or even national levels.

Prevalence of sexual abuse and its association with health-risk behaviors among Brazilian adolescents: A populational study.

BACKGROUND: Analysis of sexual abuse has usually been neglected in research at developing countries despite its everlasting consequences. This study examined the prevalence of sexual abuse among Brazilian adolescents according to data from the National School Health Survey (PeNSE) and analyzed it based on Brazilian regions, sociodemographic aspects, health information, and health-risk behaviors among Brazilian adolescents who reported having experienced sexual abuse previously. PARTICIPANTS AND SETTING: The PeNSE data were utilized, and the sample included 102,072 students from all over Brazil, aged between 11 and 19 years. METHODS: Data were collected by questionnaires and were analyzed by multivariate analysis using the Poisson regression model. RESULTS: The results denoted a relation between sexual abuse, social determinants of health variables (i.e., black, indigenous, and mixed skin color/ethnicity; Brazilian region public school, age between 15 and 18 years, and low education level of the mother), and health-risk behaviors (i.e., early sexual intercourse, having multiple sexual partners, unprotected sexual intercourse, use of tobacco, alcohol, and illicit drugs). CONCLUSION: Therefore, reports of sexual abuse are associated with risky behaviors. Given these findings, targeted interventions on sexual abuse are essential for the health of adolescents and the prevention of risky behaviors, and can also facilitate programs to prevent sexual abuse.

Narrative review of the influence of high-intensity interval training on adolescents' bone health: commentary and perspectives.

Although several benefits have been associated to high-intensity interval training (HIIT), there is a lack of clarity on the HIIT effects in adolescents, especially on bone health outcomes. To address this gap, our research aimed to perform a systematic review, which focus on the influence of HIIT on adolescents' bone health. Our search strategy was conducted on three databases (PubMed, SCOPUS, and Embase). For our review, we included articles with the following characteristics: (I) sample consisting of adolescents (10-19 years old), (II) HIIT interventions; and (III) assessment of bone health outcomes. Longitudinal and clinical trials studies with no language and year of publications restrictions were eligible to be included. A total of 63 eligible studies were identified. After removing the duplicates and screening the titles and abstracts, six articles remained to be read in full text. However, none of the articles met our criteria. Studies in which no article meets the eligibility criteria are also essential and need to be shared with the academic community because it may stimulate appropriate future investigations in this field. This lack in the review results highlights the need for further epidemiological research focusing on this topic, including high quality, large scale, and longitudinal studies, as well as randomized controlled trials to confirm or refute efficacy.
