title: Demand for health services or professionals among Brazilian adolescents according to the National School Health Survey 2015

description: ABSTRACT: Introduction: Knowing the profile of individuals who demand health services or professionals could help in the improvement and reorganization of services. However, this subject is still underexplored among adolescents. This study aimed to describe and identify characteristics related to the demand for health services or professionals by Brazilian students. Methods: Using data from the 2015 National School Health Survey, the prevalence and respective 95% confidence intervals (95%CI) of the demand for health services or professionals among students were estimated, and Poisson regression adjusted by age and region of residence was used to identify the associated factors. Results: More than half of the students demanded for health services or professionals in the last year, with a higher demand among females. The characteristics associated with the outcome were sociodemographic (female, white, private school), family (maternal schooling of 12 years or more, having meals with parents/guardians and parents’ knowledge of the adolescent’s activities in their free time), risk behaviors (alcohol consumption and sexual intercourse without a condom) and health-related issues (physical violence, wheezing, toothache, hygiene habits, and attitude to one’s own weight). Conclusion: Organizing health services in a way that takes the particularities of this population into account may provide a space to deal with subjects related to the risks to which it is exposed.

title: Use of psychoactive substances among Brazilian adolescents and associated factors: National School-based Health Survey, 2015

description: ABSTRACT: Aim: To analyze the consumption of tobacco, alcohol and illicit drugs among schoolchildren according to demographic factors, family context and mental health. Methods: We used data from the National School-based Health Survey 2015 and included in the sample 102,301 schoolchildren in the 9th grade. We estimated the prevalence of tobacco and alcohol use in the last 30 days and drug experimentation according to demographic, mental health and family context variables. Then, a bivariate analysis was performed using Pearson’s χ2 test and the unadjusted odds ratio (OR) was calculated. Finally, we conducted a multivariate analysis including independent variables with an unadjusted association (p &lt; 0.20), for each outcome, estimating the adjusted OR with a 95% confidence interval. Results: The prevalence of tobacco consumption was 5.6%; alcohol consumption, 23.8%; and drug experimentation, 9.0%. Multivariate analysis has indicated that living with parents, having meals with parents or guardian, and family supervision were associated with lower substance consumption; whereas missing classes without parental consent has increased the chances of substance use. Increased chance of substance use was also associated with white skin color, increasing age, to work, feeling lonely and having insomnia. Not having friends was associated with drug and tobacco use, but this was protective for alcohol consumption. Conclusions: Family supervision was protective for psychoactive substance use among Brazilian schoolchildren, whereas work, loneliness and insomnia have increased their chances of use.

title: Prevalence and factors associated with illicit drug use throughout life: National School Health Survey 2015

description: ABSTRACT: Introduction: The use of illicit drugs is a public health concern. This paper describes the prevalence and factors associated with the use of illicit drugs throughout life among 9th grade students attending public and private schools in daylight period in Brazil. Method: Data from the Brazilian Adolescent School-based Health Survey (PeNSE) were analyzed. Use of illicit drugs at some point in life was assessed considering marijuana, cocaine, crack, solvent-based glue, ether-based inhalants, ecstasy, and oxy. Data were analized descriptively and by the Poisson’s regression model. Results: The use of illicit drugs at least once in life was reported by 9,0% of participants, being more prevalent among girls and associated with alcohol or tobacco use, active sexual life, feeling of loneliness, little or no contact between school and parents, and the experience of familial aggressions. The outcome was inversely associated with close contact with parents and their supervision. Prevalence was higher among participants whose mothers had higher educational levels and had, who had a payed job, and who attended public schools. Discussion: The prevalence of lifetime use of illicit drugs was stable when the three PeNSE samples were compared, but it resulted more common among girls in 2015 for the first time and was associated with the same conditions found in prior studies. Conclusion: Family and school appear to be protective factors, especially when there is direct supervision and care. It is important that both girls and boys are given the same attention when it comes to this this subject.

title: Evolution of the report of suffering bullying among Brazilian schoolchildren: National Scholl Health Survey - 2009 to 2015

description: ABSTRACT: Introduction: The purpose of this paper was to compare the tendency of bullying across Brazilian capitals, considering the editions of National Scholl Health Survey (PeNSE) 2009, 2012 and 2015, and to describe the prevalence of bullying by sex, age and administrative dependence of the school in the 2015 sample. Methodology: The prevalence of bullying and its 95% confidence interval (95%CI) were assessed per State capital and for all capitals. 95%CI was used to check for differences in the period. In the last edition, two samples were analyzed: sample 1 represents the students of the 9th year of Elementary School and sample 2 holds students from 13 to 17 years of age, from the 6th to 9th grade of Elementary and High Schools. Results: The report of suffering bullying by 9th graders in Brazilian capitals increased from 5.4% (95%CI 5.1 - 5.7), in 2009, to 7.2% (95%CI 6.6 - 7.8), in 2012, staying at 7.4% (95%CI 7.1 - 7.7) in 2015. Descriptive analysis for Brazil showed variation by age, as adolescents aged 13 years suffered more bullying than those aged 14, 15 and 16 years. Boys usually report more this problem than girls, as well as public school students, but with overlapping CI. Discussion: The study pointed 37% increase in the prevalence of bullying between 2009 and 2015 in Brazilian capitals by. Conclusion: This study reiterates that Brazilian schools are still a space for violence reproduction, which makes it urgent to make progress in prevention and minimization of bullying at schools based on the concept of health promotion and integral care.

title: Trends in risk and protective factors for non-communicable diseases in the population with health insurance in Brazil from 2008 to 2015

description: ABSTRACT: Objective: To analyze trends in risk and protective factors for non-communicable diseases (NCD) and access to preventive tests in the population with health insurance in Brazilian state capitals between 2008 and 2015. Methods: This is a cross-sectional study that analyzed data collected from the Surveillance of Risk and Protective Factors for non-communicable diseases (NCD) Telephone Survey (Sistema Nacional de Vigilância de Doenças Crônicas por Inquérito Telefônico - Vigitel) on adults aged 18 years and older. We analyzed trends in NCD indicators among health insurance users in approximately 30 thousand interviews done between 2008 and 2015. We used the simple linear regression model to calculate the trends. Results: Health insurance users showed an increase in the prevalence of protective factors such as fruit and vegetable consumption, and physical activity in leisure time. Also, there was a decrease in risk factors such as smoking and soft drink consumption, increase in mammography coverage, and a drop in smoking prevalence. However, overweight, obesity, and diabetes increased. Conclusion: There are differences according to gender, and, in general, women accumulate more protective factors and men, more risk factors.

title: Simultaneous oral health risk behaviors among adolescents: evidence from the National School-based Student Health Survey

description: ABSTRACT: Objective: To investigate the prevalence of simultaneous oral health risk behaviors and associated factors among Brazilian adolescents. Methods: The study comprised data of 109,104 adolescents participating in the Brazilian National School-based Student Health Survey. The simultaneous presence of less frequent toothbrushing (E), current smoking (C), no visits to the dentist (D), low fruit intake (F), and high sugar intake (A) was assessed by comparison of observed/expected prevalence (OP/EP). Logistic regression was used to assess sociodemographic and family factors associated with the clustering patterns of oral health risk behaviors. Results: The simultaneous occurrence of two or more oral health risk behaviors was of 60.40%. The highest prevalence values were found for the following patterns with OP/EP over 1.20: EDF, CFA, and EDFA. The odds for two or more combined oral health risk behaviors were higher for adolescents whose parents did not participate in homework, from public schools, males, and of Asian or Indigenous ethnicity (OR &gt; 1.00; p &lt; 0.05). Low family affluence level (FAL) acted as a risk factor for the pattern ECDFA (OR = 2.58; p = 0.009), while low and mean FAL functioned as protection factors for the pattern CFA (OR = 0.71; p &lt; 0.001, and OR = 0.76; p = 0.011). Conclusion: The prevalence of simultaneous oral health risk behaviors was low and negatively associated with sociodemographic and family factors. Interventions aiming at reducing these behavior patterns should prioritize the groups that have been identified as being at most risk.

title: Prevalence of physically active adolescents in Brazilian capitals: National Adolescent School-based Health Survey 2012 and 2015

description: ABSTRACT: Objective: To compare the prevalence of physically active adolescents living in Brazilian capitals, using 2012 and 2015 National Adolescent School-based Health Survey. Method: The sample consisted of 61,145 (2012) and 51,192 (2015) adolescents who were residents in 27 Brazilian capitals and were attending the 9th year of elementary school. The globally estimated physical activity indicator with the cutoff point of 300 minutes or more per week was used to determine the prevalence of physically active adolescents in both surveys. The prevalence rates were stratified by socio-demographic characteristics (gender, age, maternal schooling and skin color) and by capital of residency. Descriptive statistics were used for comparisons considering 95% confidence intervals. Results: The respective prevalence rates of physically active adolescents observed in 2012 (21.0%; 95%CI 20.3 - 21.7) and 2015 (20.7%; 95%CI 20.1 - 21.3) were similar, independently of the sociodemographic characteristics. In considering the 27 capitals, a reduction in the prevalence of physically active adolescents from 2012 to 2015 was observed only in Belém. Conclusion: Overall, no changes in the prevalence of physically active adolescents residing in urban centers was observed from 2012 to 2015. These findings evidence the need for new public policies in order to enhance and promote the practice of physical activity among Brazilian adolescents, as well as the expansion of existing ones.

title: Decolorization of remazol brilliant blue R with laccase from Lentinus crinitus grown in agro-industrial by-products

description: ABSTRACT Lentinus crinitus is a white-rot fungus that produces laccase, an enzyme used for dye decolorization. Enzyme production depends on cultivation conditions, mainly agro-industrial by-products. We aimed to produce laccase from Lentinus crinitus with agro-industrial by-products for dye decolorization. Culture medium had coffee husk (CH) or citric pulp pellet (CP) and different nitrogen sources (urea, yeast extract, ammonium sulfate and sodium nitrate) at concentrations of 0, 0.7, 1.4, 2.8, 5.6 and 11.2 g/L. Enzymatic extract was used in the decolorization of remazol brilliant blue R. CH medium promoted greater laccase production than CP in all evaluated conditions. Urea provided the greatest laccase production for CH (37280 U/L) as well as for CP (34107 U/L). In CH medium, laccase activity was suppressed when carbon-to-nitrogen ratio changed from 4.5 to 1.56, but the other nitrogen concentrations did not affect laccase activity. For CP medium, reduction in carbon-to-nitrogen ratio from 6 to 1.76 increased laccase activity in 17%. The peak of laccase activity in CH medium occurred on the 11th day (41246 U/L) and in CP medium on the 12th day (32660 U/L). The maximum decolorization within 24 h was observed with CP enzymatic extract (74%) and with CH extract (76%).

title: Soft drink consumption and body mass index in Brazilian adolescents: National Adolescent Student Health Survey

description: ABSTRACT: Objective: To estimate the association between soft drink consumption and body mass index (BMI) in eutrophic and overweight adolescents. Methods: We used data from the National Adolescent Student Health Survey (Pesquisa Nacional de Saúde do Escolar - PeNSE) of 2009. The dependent variable (outcome) was the tertiles of BMI score (zBMI), and the main independent variable (exposure) was the consumption of sugar-sweetened soft drinks. The models included age, school type, home goods and services score, and maternal schooling as adjustment variables. We estimated the association between exposure and outcome by using multinomial regression models, stratified by gender, and eutrophic and overweight subgroups. Results: 23.8% of the adolescents evaluated were overweight, and 21.7% reported consuming soft drinks daily. For eutrophic boys, those who consumed soft drinks had a greater chance of being in higher zBMI tertiles than non-consumers. For overweight adolescents, both male and female, soft drink consumption was associated with a lower chance of being in the highest tertile of zBMI score. Conclusion: The results show the possibility of reverse causality between consumption of sweetened soft drinks and zBMI in the overweight adolescents group. For eutrophic male adolescents, soft drink consumption can potentially increase the chances of having higher zBMI, which reinforces the need for measures to significantly reduce the consumption of this beverage.
