Patterns of health-related behaviours among adolescents: a cross-sectional study based on the National Survey of School Health Brazil 2012.

OBJECTIVES: The aim of this study was to analyse the clustering of multiple health-related behaviours among adolescents and describe which socio-demographic characteristics are associated with these patterns. DESIGN: Cross-sectional study. SETTING: Brazilian schools assessed by the National Survey of School Health (PeNSE, 2012). PARTICIPANTS: 104 109 Brazilian ninth-grade students from public and private schools (response rate=82.7%). METHODS: Exploratory and confirmatory factor analyses were performed to identify behaviour clustering and linear regression models were used to identify socio-demographic characteristics associated with each one of these behaviour patterns. RESULTS: We identified a good fit model with three behaviour patterns. The first was labelled 'problem-behaviour' and included aggressive behaviour, alcohol consumption, smoking, drug use and unsafe sex; the second was labelled 'health-compromising diet and sedentary behaviours' and included unhealthy food indicators and sedentary behaviour; and the third was labelled 'health-promoting diet and physical activity' and included healthy food indicators and physical activity. No differences in behaviour patterns were found between genders. The problem-behaviour pattern was associated with male gender, older age, more developed region (socially and economically) and public schools (compared with private). The 'health-compromising diet and sedentary behaviours' pattern was associated with female gender, older age, mothers with higher education level and more developed region. The 'health-promoting diet and physical activity' pattern was associated with male gender and mothers with higher education level. CONCLUSIONS: Three health-related behaviour patterns were found among Brazilian adolescents. Interventions to decrease those negative patterns should take into account how these behaviours cluster together and the individuals most at risk

Out-of-Home Food Consumers in Brazil: What Do They Eat?

Considering the increased contribution of foods consumed outside home and their potential impact on diet, this study aims to identify eating out patterns and their association with nutritional dietary quality in Brazil. We used the Individual Food Intake Survey 2008-2009, conducted with 34,003 individuals aged 10 and up. We used factor analysis by principal component to identify out-of-home eating patterns and linear regression to explore the association between patterns scores and dietary quality. We identified three food patterns. The Traditional meal pattern carried more rice, beans, meat, roots and tubers, pasta, vegetables and eggs. The typical Brazilian breakfast/tea pattern carried more fresh bread, margarine, milk, cheese and butter. The Ultra-processed food pattern carried more ready-to-eat meals and soft drinks. The traditional meal pattern was positively associated with calories from proteins, fiber, iron, potassium and sodium densities, whereas typical Brazilian breakfast/tea and ultra-processed food patterns were positively associated with energy density, the percentage of calories from lipids or carbohydrates, trans fat and free sugar. Out-of-home eating may have a negative impact on nutritional dietary quality when based on ultra-processed food. However, it is possible to maintain a healthy out-of-home diet with adherence to traditional Brazilian cuisine.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Nucleo Pesquisas Epidemiol Nutr & Saude NUPENS, BR-01246907 Sao Paulo, BrazilUniv Sao Paulo FMUSP, Fac Med, Dept Med Prevent, BR-01246903 Sao Paulo, BrazilUniv Fed Sao Paulo UNIFESP, Dept Polit Publ & Saude Colet, BR-11015020 Sao Paulo, BrazilUniv Fed Uberlandia, Fac Med, Curso Nutr, BR-38400902 Uberlandia, MG, BrazilInst Def Consumidor IDEC, BR-05002000 Sao Paulo, BrazilUniv Fed Sao Paulo UNIFESP, Dept Polit Publ & Saude Colet, BR-11015020 Sao Paulo, BrazilWeb of Scienc

Health-related patterns and chronic kidney disease in the Brazilian population: National Health Survey, 2019

ObjectiveThe aim of this study was to identify patterns related to health and their association with chronic kidney disease (CKD) in the Brazilian population.MethodsWe used data from the National Health Survey (PNS), 2019. Participants were interviewed and answered questions related to socioeconomic and demographic information (gender, age, education, race/color), health conditions (presence of hypertension, diabetes mellitus, hyperlipidemia, cardiovascular disease, overweight and CKD) and lifestyle (smoking, alcohol consumption, physical activity and food consumption). To identify patterns, we used exploratory factor analysis. We performed logistic regression models to describe the association of CKD with each pattern in crude models and adjusted for gender, age group, education level and race/color.ResultsA total of 90,846 individuals were evaluated. The prevalence of CKD was 1.49% (95% CI: 1.3–1.6). Three health-related patterns – metabolic factors, behavioral risk factors and behavioral protective factors – were identified by factor analysis. Metabolic factors were determined by the presence of hypertension, diabetes mellitus, hyperlipidemia and cardiovascular diseases. Behavioral risk factors were determined by smoking, alcohol consumption, regular consumption of soft drinks, sweets and artificial juices, and high salt consumption. The protective behavioral factors were established by the practice of physical activity and regular consumption of vegetables and fruits. Participants of the highest tertile for metabolic factors were more likely to have CKD in the adjusted model (OR = 3.61, 95% CI: 2.69–4.85), when compared to those of the lower tertile.ConclusionThe pattern referring to metabolic factors was associated with a higher chance of presenting CKD

Associação entre supervisão parental e vitimização e perpetração de bullying em adolescentes brasileiros, Pesquisa Nacional de Saúde do Escolar 2015

Objective: To analyze the association between parental supervision characteristics and different bullying roles among Brazilian school adolescents. Methods: Cross-sectional study that used data from the National School Health Survey (PeNSE) 2015. Frequent meals with parents/guardians, knowledge about free time, and checking homework were the parental practices assessed. Logistic regression was used for association between 4 these practices and bullying (perpetration and victimization), presented as oddsratio (OR) and 95% confidence intervals (95%CI). Results: Among 102,072 school adolescents, frequent meals with parents or guardians [ORvitim=0.86 (95%CI 0.84;0.89); ORperp=0.85 (95%CI 0.82;0.88)], checking homework [ORvitim=0.95 (95%CI 0.92;0.97); ORperp=0.76 (95%CI:0.74;0.78)], and parents or guardian’s knowledge of students’ free time [ORperp=0.70 (95%CI 0.68;0.73] were inversely associated with bullying. Conclusion: Greater parental supervision reduced the chance of victimization and perpetration bullying among adolescents.Objetivo: Analizar la asociación entre las características de la supervisión parental y los diferentes roles del bullying entre adolescentes brasileños. Métodos: Estudio transversal con datos de la Encuesta Nacional de Salud Escolar de Adolescentes (PeNSE) 2015. Las comidas frecuentes con los padres/tutores, el conocimiento sobre el tiempo libre y la verificación de la tarea fueron las prácticas parentales evaluadas. Se utilizo regresión logística para la asociación entre prácticas y bullying (perpetración y victimización), presentada como razón de probabilidades (RP) e intervalos de confianza del 95% (IC95%). Resultados: Entre102.072 estudiantes, comidas frecuentes [RPvitim=0,86 (IC95%0,84;0,89); RPperp=0,85 (IC95% 0,82;0,88)] y verificación de la tarea [RPvitim=0,95 (IC95% 0,92;0,97); ORperp=0,76 (IC95% 0,74;0,78)] y conocimiento de los padres/tutores sobre el tiempo libre [RPperp=0,70 (IC95% 0,68;0,73)] se asociaron inversamente con el acoso.

Progress and setbacks in socioeconomic inequalities in adolescent health-related behaviours in Brazil: results from three cross-sectional surveys 2009-2015.

OBJECTIVES: Despite some progress, Brazil is still one of the most unequal countries, and the extent of socioeconomic inequalities in adolescent health is unclear. We assessed trends in socioeconomic inequalities in adolescent's health-related behaviours in Brazil between 2009 and 2015. DESIGN: We used cross-sectional data from the Brazilian National Survey of School Health carried out in 2009, 2012 and 2015. SETTING: Brazilian state capitals. PARTICIPANTS: Students attending ninth grade from public and private schools in Brazilian state capitals in 2009 (60 973 students), 2012 (61 145 students) and 2015 (51 192 students). MAIN OUTCOME MEASURE: We assessed 12 health-related behaviours (irregular fruit, vegetables and bean consumption; regular soft drink consumption; irregular physical activity; alcohol, drug and tobacco use; unsafe sex; involvement in gun fights; bullying victimisation and domestic violence victimisation), under the broad domains of lifestyle risk behaviours, engagement in risky activities and exposure to violence. Socioeconomic status was assessed through an asset-based wealth index derived from principal component analysis. Absolute and relative inequalities in these health behaviours and inequalities trends were investigated. RESULTS: From 2009 to 2015, prevalence of certain harmful health-related behaviours increased, such as unsafe sex (21.5% to 33.9%), domestic violence (9.5% to 16.2%), bullying victimisation (14.2% to 21.7%) and irregular consumption of beans (37.5% to 43.7%). Other indicators decreased: alcohol use (27.1% to 23.2%), irregular physical activity (83.0% to 75.6%) and consumption of soft drinks (37.2% to 28.8%). Over the period, we found consistent evidence of decreasing health inequalities for lifestyle behaviours (fruit, bean and soft drink consumption) and alcohol use, set against increasing inequalities in violence (domestic violence, fights using guns and bullying victimisation). CONCLUSION: Socioeconomic inequality increased in the violence domain and decreased for lifestyle behaviours among Brazilian adolescents. Widening gaps in violence domain urge immediately policy measures in Brazil

Educational inequality in consumption of in natura or minimally processed foods and ultra-processed foods: The intersection between sex and race/skin color in Brazil

BackgroundIt remains uncertain how the intersection between educational, gender, and race/skin color inequalities influences food consumption in Brazil. In this study, we examined the educational inequality in the consumption of in natura/minimally processed and ultra-processed foods by Brazilians with an intersectional perspective between sex and race/color.MethodsWe used cross-sectional data from the Telephone Surveillance System (VIGITEL 2019), comprising 52,443 participants ≥ 18 years. Daily food consumption was considered high when consumption of ≥5 foods for each food group was reported the day before the survey. Educational inequality in food consumption was assessed by the slope index of inequality (SII) and the relative index of inequality (RII) according to sex and race/color (White; Black/Brown). Positive SII and RII values > 1.0 indicate higher food consumption among more educated participants.ResultsThe consumptions of in natura/minimally processed and ultra-processed foods were more prevalent in those with the highest level of education (≥12 years) and intermediate education (9–11 years), respectively. However, highly educated White women had higher consumption of in natura/minimally processed foods than Black women with the same education level, and White men in low and intermediate school levels had higher consumption of these foods than Black men with the same education levels. We found higher absolute educational inequality for in natura/minimally processed foods among White women (SII 21.8, 95% CI 15.3, 28.4) and Black/Brown men (SII 19.3, 95% CI 12.5, 26.1). Black/Brown men (SII 7.3, 95% CI 0.5, 14.0) and Black/Brown women (SII 5.6, 95% CI 1.0, 10.2) had higher absolute educational inequality than White men (SII −3.3, 95% CI −10.9, 4.3; P = 0.04) in the consumption of ultra-processed foods.ConclusionEducational inequalities influenced the consumption of in natura/minimally processed more than ultra-processed foods, and, for the latter, inequalities were greater among Black/Brown men and women than among White men

Implantação e impacto do Programa Nacional de Suplementação de Ferro no município de Viçosa - MG

Objetivou-se avaliar a implantação do Programa Nacional de Suplementação de Ferro no município de Viçosa/MG e seu impacto em lactentes não anêmicos de 6 a 18 meses de idade, atendidos pelas Equipes de Saúde da Família. Realizou-se entrevistas aos profissionais de nível superior e às mães/responsáveis pelas crianças. As crianças não anêmicas e que não recebiam suplementação anteriormente (n=133) foram suplementadas com xarope de sulfato ferroso por seis meses. Realizou-se dosagem de hemoglobina, avaliação antropométrica e de condições socioeconômicas, antes e após os seis meses. Classificou-se como alta adesão as crianças que ingeriram 75% ou mais da dose prescrita e como baixa adesão as demais, de acordo com o referido pelas mães. Sobre a implantação do PNSF no município, observou-se que o sistema de distribuição nem sempre foi acessível ao grupo prioritário e houve ausência de capacitação e motivação da maioria dos Agentes Comunitários de Saúde; sobre o grupo prioritário observou-se ausência de divulgação para promoção do PNSF, além de sensibilização e educação somente de parte das mães; quanto ao suplemento as crianças tiveram baixa adesão e a dosagem não foi efetiva na prevenção da anemia. Portanto, a implantação do PNSF no município revelou entraves operacionais importantes.The scope of this work was to evaluate the implementation of the National Iron Supplementation Program (NISP) in Viçosa in the State of Minas Gerais and its impact on 6- to 18-month-old non-anemic infants assisted by the Family Health Teams. Interviews were conducted with the professionals and with the children's mothers/guardians. The non-anemic children who didn't receive the earlier supplementation (n=133) were given ferrous sulphate syrup for six months. Hemoglobin dosage, anthropometric evaluation and a socioeconomic survey were conducted before and after the six-month period. Children who ingested 75% or more of the prescribed dosage were classified as high adhesion, while the others were classified as low adhesion, according to the mothers' testimonials. With respect to the implementation in the city, the distribution system was not always available to the priority group and there was a lack of training and motivation on the part of most Community Health Agents. The lack of promotion of NISP among the priority group was detected, apart from a mothers' awareness drive. Regarding diet supplementation, children showed low adhesion and the dosage wasn't effective in preventing anemia. Therefore, important operational barriers to implementation were observed

Efetividade superior do esquema diário de suplementação de ferro em lactentes

OBJECTIVE: To assess the effectiveness of weekly and daily schemes of preventive supplementation with supplementary iron to prevent iron deficiency anemia in non-anemic infants. METHODS: A prospective population study with a quantitative approach and preventive intervention was performed in the city of Viçosa, Southeastern Brazil, in 2007-8. A total of 103 non-anemic children, aged between six and 18 months of age, were selected, corresponding to 20.2% of the children registered with and cared for by Equipes de Saúde da Família (Family Health Teams). Children were divided into two supplementation groups: daily dosage recommended by the Sociedade Brasileira de Pediatria (Brazilian Society of Pediatrics) (group 1, n=34) and weekly dosage recommended by the Brazilian Ministry of Health (group 2, n=69). Assessments were made in the beginning of the study and after six months, with hemoglobin dosage (portable ß-Hemoglobin-meter) and anthropometric and dietary assessments being performed and socioeconomic questionnaire applied. Impact indicators used were prevalence of anemia, hemoglobin variation, adherence to and side effects of supplements. RESULTS: Groups were homogeneous in terms of socioeconomic, biological and before-intervention health variables. After six months of supplementation, higher means of hemoglobin were found in group 1 than in group 2 (11.66; SD=1.25 and 10.95; SD=1.41, respectively, p=0.015); in addition to lower prevalences of anemia (20.6% and 43.5%, respectively, p=0.04). Only "supplementation time" influenced severe anemia (p=0.009). Statistically significant differences were not found for the "adherence to supplementation" and "side effects" variables. CONCLUSIONS: The daily dosage recommended by the Sociedade Brasileira de Pediatria was found to be more effective to prevent anemia in infants, when compared to the dosage used by the Ministry of Health. The weekly dosage recommended by the Brazilian government program needs to be reviewed to increase the effectiveness of prevention of anemia in infants cared for in public health services.OBJETIVO: Evaluar la efectividad de esquemas, diario y semanal, de suplementación profiláctica de hierro medicamentoso en la prevención de anemia ferropriva en lactantes no anémicos. MÉTODOS: Estudio poblacional, prospectivo, de abordaje cuantitativo con intervención profiláctica, realizado en el municipio de Vinosa, Sureste de Brasil, en 2007/8. Fueron seleccionados 103 niños no anémicos, entre seis y 18 meses de edad, correspondiendo a 20,2% de los niños catastrados y atendidos por los Equipos de Salud de la Familia. Los niños fueron divididos en dos grupos de suplementación: dosificación diaria recomendada por la Sociedad Brasilera de Pediatría (grupo 1, n=34) y dosificación semanal establecida por el Ministerio de la Salud (grupo 2, n=69). Las evaluaciones ocurrieron en el inicio del estudio y posterior a seis meses, siendo realizadas dosificación de hemoglobina (b-homoglobinómetro portátil), evaluación antropométrica y dietética, y aplicación de cuestionario socioeconómico. Los indicadores de impacto utilizados fueron la prevalencia de anemia, variación de hemoglobina, adhesión y efectos adversos a los suplementos. RESULTADOS: Los grupos se mostraron homogéneos con relación a las variables socioeconómicas, biológicas y de salud anteriores a la intervención. Posterior a seis meses de suplementación, se observaron mayores promedios de hemoglobina en el grupo 1 con relación al grupo 2, (11,66; DP=1,25 e 10,95; DP=1,41, respectivamente, p=0,015); así como menores prevalencias de anemia (20,6% y 43,5%, respectivamente, p=0,04). Sólo el tiempo de suplementación influyó en la anemia grave (p=0,009). No fueron encontradas diferencias estadísticamente significativas para las variables adhesión al suplemento y efectos adversos. CONCLUSIONES: La dosificación diaria recomendada por la Sociedad Brasilera de Pediatría se mostró más efectiva en la prevención de la anemia en lactantes, al compararla con la dosificación utilizada por el Ministerio de la Salud. La dosificación semanal recomendada por el programa de gobierno brasilero precisa ser reevaluada para aumentar su efectividad en la prevención de anemia en niños atendidos en servicios públicos de salud.OBJETIVO: Avaliar a efetividade de esquemas, diário e semanal, de suplementação profilática de ferro medicamentoso na prevenção da anemia ferropriva em lactentes não anêmicos. MÉTODOS: Estudo populacional, prospectivo, de abordagem quantitativa com intervenção profilática, realizado no município de Viçosa, MG, em 2007/8. Foram selecionadas 103 crianças não anêmicas, entre seis e 18 meses de idade, correspondendo a 20,2% das crianças cadastradas e atendidas pelas Equipes de Saúde da Família. As crianças foram divididas em dois grupos de suplementação: dosagem diária recomendada pela Sociedade Brasileira de Pediatria (grupo 1, n=34) e dosagem semanal preconizada pelo Ministério da Saúde (grupo 2, n=69). As avaliações ocorreram no início do estudo e após seis meses, sendo realizadas dosagem de hemoglobina (ß-hemoglobinômetro portátil), avaliação antropométrica e dietética, e aplicação de questionário socioeconômico. Os indicadores de impacto utilizados foram a prevalência de anemia, variação de hemoglobina, adesão e efeitos adversos aos suplementos. RESULTADOS: Os grupos se mostraram homogêneos quanto às variáveis socioeconômicas, biológicas e de saúde anteriores à intervenção. Após seis meses de suplementação, observaram-se maiores médias de hemoglobina no grupo 1 em relação ao grupo 2, (11,66; DP=1,25 e 10,95; DP=1,41, respectivamente, p=0,015); além de menores prevalências de anemia (20,6% e 43,5%, respectivamente, p=0,04). Apenas o tempo de suplementação influenciou na anemia grave (p=0,009). Não foram encontradas diferenças estatisticamente significantes para as variáveis adesão ao suplemento e efeitos adversos. CONCLUSÕES: A dosagem diária recomendada pela Sociedade Brasileira de Pediatria mostrou-se mais efetiva na prevenção da anemia em lactentes, quando comparada à dosagem utilizada pelo Ministério da Saúde. A dosagem semanal recomendada pelo programa do governo brasileiro precisa ser reavaliada para aumentar sua efetividade na prevenção de anemia em crianças atendidas em serviços públicos de saúde
