Enfermagem na atenção primária em saúde no screening de adolescentes com excesso de peso

One of the Primary Health Care strategies for adolescent health is the growth and development follow-up and the early detection of overweight adolescents. Even though the School Health Program in Brazil proposes to evaluate the nutritional state of the school population in the corresponding community health units, not all cities have adhered to the Program and many nurses do not recognize overweight as a problem in their territory. The objective of the study was to identify the nurse´s participation in the screening of overweight adolescent students in their work territory. Cross sectional study conducted in eight state supported schools of the municipality of Natal/RN and in four Primary Health Units. The total student population was 27.277. A stratified sample was statistically calculated based on the student population of the four city geographical zones: 112 North , 74 West; 108 East; and 78 South, totalizing 372 adolescents. The students were selected by a probability process where eight schools were first selected, two per district, until the number per subsample in each district was reached. Four primary health nurses, responsible for the health units were included. Two instruments were used for data collection, a screening questionnaire and a semi-structured interview form for questioning of the nurses. The content of both instruments was validated. Anthropometric and health data were collected from the students and analyzed with descriptive and analytical statistics. Interview data were transcribed and submitted to content analysis. The nursing diagnosis of overweight was identified in 50 (13,5%) of the adolescents and its association with consumption of foods that have cardiovascular risk (canned foods, pasta and fried food). An association of the nursing diagnosis was identified with family history (diabetes, hypertension, obesity, and kidney disease). The nurses judged that care of overweight adolescents was important but noted difficulties because of the absence of this population in the health units, because of their work overload, and the lack of school articulation. The nurses do not have impacting actions with this population and delegate the responsibility to other professionals. It is concluded that overweight is a nutritional problem relevant to the adolescent school population in Natal/RN, with a 13,5% prevalence and that it is related to food consumption with cardiovascular risk and family health history. The nurses consider overweight as an important public health problem but do not envision ways to maintain linkage with adolescents and with the school to promote the needed care

Variações no balanço catiônico do solo induzidas pela adubação potássica e efeitos na cultura do alho vernalizado

Avaliaram-se os efeitos das relações (Ca+Mg)/K do solo sobre o desenvolvimento, absorção de nutrientes e produção de bulbos na cultura do alho cv. Roxo Pérola de Caçador conduzindo experimento no período de maio a outubro de 1990 em vasos de cimento amianto contendo 50 kg de terra, em casa de vegetação telada. Os tratamentos consistiram de aplicações de doses de potássio visando atingir relações (Ca+Mg)/K no complexo de troca do solo próximas a 170; 50; 35; 20; 12,5; 7,5; 5,0; 3,5 e 2,0. Verificaram-se aumentos na concentração de K, Ca e Mg na solução do solo proporcionais à elevação do teor de K trocável. As concentrações foliares de K e Mn diminuiram proporcionalmente às relações (Ca+Mg)/K do solo, ocorrendo o inverso com as concentrações de Ca e Mg. A absorção dos demais nutrientes não foi influenciada pelos tratamentos. A relação (Ca+Mg)/K influenciou a produção de bulbos e a altura das plantas durante todo o ciclo, sendo que os menores valores desta relação, caracterizados por excesso de K, inibiram mais o desenvolvimento e a produção de bulbos. A porcentagem de K no complexo de troca, seguida da relação K/(Ca+Mg)1/2 e do K trocável do solo foram os índices que melhor correlacionaram com a produção de bulbos.

Fertilização potássica na cultura do alho vernalizado

O objetivo do presente trabalho foi verificar a validade do parcelamento da adubação potássica, bem como a época mais adequada de aplicação, no controle do superbrotamento e no desenvolvimento e produção de bulbos na cultura do alho vernalizado (cv. Roxo Pérola de Caçador). Foram instalados dois experimentos em estufa agrícola, em vasos de cimento amianto com capacidade para 55 L de terra. O experimento 1 consistiu de sete épocas de aplicação da metade da dose de potássio necessária para a cultura, aos 50, 60, 70, 81, 91, 101 e 111 dias após a emergência (dae), sendo que o experimento 2 consistiu da aplicação de quatro doses de potássio no plantio combinadas a outras quatro em cobertura, aos 81 dae. O parcelamento da adubação potássica em diferentes estádios de desenvolvimento não influenciou a produção de bulbos e o superbrotamento na cultura do alho. A absorção de potássio, cálcio e magnésio pelas plantas foi influenciada pela adubação potássica no plantio e em cobertura, observando-se um efeito antagônico do potássio sobre a absorção de cálcio e magnésio. A elevação no nível de potássio no solo por ocasião do plantio proporcionou aumento na produção de bulbos, sendo que esta não foi influenciada por variações na dose de adubação potássica em cobertura.

Doses de fósforo e zinco na cultura do alho em condições de casa de vegetação

A adubação fosfatada promove o aumento de produtividade na cultura do alho, mas doses de fósforo (P) podem proporcionar a deficiência de zinco (Zn) na planta, sobretudo em solos com baixos teores deste micronutriente. O objetivo do trabalho foi verificar o efeito da interação entre P e Zn no solo sobre o desenvolvimento e produção de plantas de alho. Foram instalados três experimentos, cada um com um tipo de solo, em vasos com 17 kg de solo, em casa de vegetação telada. Empregou-se delineamento em blocos casualizados em esquema fatorial com 4 doses de P (0, 100, 200 e 400 mg dm-3) utilizando-se superfosfato triplo e 4 doses de Zn (0, 2,5, 5,0 e 10 mg dm-3) aplicados na forma de ZnSO4.7H2O, ambos incorporados ao solo, com três repetições. A produtividade e o desenvolvimento de plantas de alho foram influenciados, isoladamente, pelas doses de P e Zn, não havendo a interação entre esses nutrientes. Para os solos Neossolo Quartzarênico (NQ) textura arenosa, Latossolo Vermelho Distrófico (LE) textura média e Latossolo Vermelho Distroférrico (LR), textura argilosa, as melhores doses de P para a produção de alho foram de 190, 400 e 400 mg dm-3 e para o Zn de 2,2; 6,5 e 5,1 mg dm-3 respectivamente.

Nutrition-related habits and associated factors of Brazilian adolescents

To investigate the nutrition-related habits (NRH) of Brazilian adolescents and evaluate the associations with risk factors.Cross-sectional school-based was carried out among high school adolescents aged 14-18 years (n = 1,759) from public and private schools from two cities. The NRH were investigated by the weekly consumption of vegetables, fruit, sweet food and fried food. Risk factors investigated were: city, sex, age, socioeconomic status and nutritional status. In statistics, Poisson regression was used with robust variance adjustment.Data indicated low consumption of fruits and vegetables, 70.0 and 71.0%, respectively, and high consumption of sweets and fried food, 66.7 and 63%, respectively. Boys showed risk of inadequate intake of vegetables [prevalence ratios (PR) 1.10, 95% CI 1.01-1.16] and fruit (PR 1.09, 95% CI 1.01-1.16). Furthermore, adolescents who live in Maringa had greater likelihood of consuming vegetables and fruit (20 and 25%, respectively). However, they presented risk of inadequate consumption of sweets (PR 1.19, 95% CI 1.11-1.28) for adolescents who live in Presidente Prudente.We concluded that inadequate NRH show high prevalence among adolescents and indicate the need to employ educational strategies that promote the adoption of more healthy habits and behaviors.

Modifiable risk factors for overweight and obesity in children and adolescents from São Paulo, Brazil

Background: Brazil is currently experiencing a nutrition transition: the displacement of traditional diets with foods high in saturated fat, sodium, and cholesterol and an increase in sedentary lifestyles. Despite these trends, our understanding of child obesity in Brazil is limited. Thus, the aims of this study were (1) to investigate the current prevalence of overweight and obesity in a large sample of children and adolescents living in São Paulo, Brazil, and (2) to identify the lifestyle behaviors associated with an increased risk of obesity in young Brazilians.Methods: A total of 3,397 children and adolescents (1,596 male) aged 7-18 years were randomly selected from 22 schools in São Paulo, Brazil. Participants were classified as normal weight, overweight, or obese based on international age-and sex-specific body mass index thresholds. Selected sociodemographic, physical activity, and nutrition behaviors were assessed via questionnaire.Results: Overall, 19.4% of boys and 16.1% of girls were overweight while 8.9% and 4.3% were obese. Two-way analysis of variance revealed that the prevalence of overweight and obesity was significantly higher in boys and in younger children when compared to girls and older children, respectively (P < 0.05 for both). Logistic regression analysis revealed that overweight was associated with more computer usage, parental encouragement to be active, and light soft drink consumption after controlling for differences in sex, age, and parental education (P < 0.05 for all). Conversely, overweight was associated with less active transport to school, eating before sleep, and consumption of breakfast, full-sugar soft drinks, fried food and confectionery (P < 0.05 for all).Conclusions: Our results show that obesity in São Paulo children and adolescents has reached a level equivalent to that seen in many developed countries. We have also identified three key modifiable factors related to obesity that may be appropriate targets for future intervention in Brazilian youth: transport mode to school, computer usage, and breakfast consumption.

Desempenho muscular e equilíbriu postural em idosas frágeis residentes na comunidade

Human aging is physiological process causes alterations in several systems of the organism. In the musculoskeletal system, a main change is the decreased muscle strength, that in the lower extremity, compromises the ability to respond quickly with enough strength to prevent falls, causing alterations in postural balance. Currently, many researchers have study the human frailty, defined as a multifactorial syndrome, with excess of vulnerability to stressors, reducing ability in maintaining or regulating homeostasis. Its characteristics are directly related to physical function. Aim: To analyze muscle performance and postural balance in frail and pre-frail elderly women, and to compare them according with the frailty phenotypes criteria proposed by Fried 2001. Method: 39 frail elderly women living in the community, aged 65 years and older, were assessed muscle performance of lower extremity using isokinetic dynamometer and postural balance using Berg s balance scale and computerized baropodometry. Results: There was significant difference in plantar flexor, knee flexor and knee extensor strength, in anteroposterior (AP) oscillation with eyes open and on Berg s scores between groups. A weak correlation was observed between strength and balance. Conclusion: The results suggest that the frail elderly present worse muscle performance in lower extremity and worse postural balance compared to the pre-frail elderly. There were correlations between muscle performance and balance impairments in these elderly, but several variables are also involved in maintaining postural balance

Síndrome da fragilidade e fatores associados em idosos comunitários do município de Santa Cruz RN

The frailty in the elderly is characterized by decreased physiological reserves, and is associated with increased risk of disability and high vulnerability to morbidity and mortality. This study is part of a multicentric project on Frailty in Elderly Brazilians (REDE FIBRA). Aims: to investigate characteristics, prevalence and associated factors related to frailty. Metodology: We interviewed 391 elderly patients aged 65 years, selected randomly. Data collection was performed using a multidimensional questionnaire containing information about socio-demographic and clinical variables. To characterize the frail elderly, was considered the phenotype proposed by Fried. Data were analyzed using descriptive statistics, bivariate analysis (χ ²) and binary logistic regression. Results: The prevalence of frailty was 17.1%. In the final model of multivariate analysis, was obtained as factors associated with frailty: advanced chronological age (p <0.001), have comorbidity (p <0.035), show dependence on performing basic activities of daily living (p <0.010) and instrumental (p <0.003) and have poor perception of health status (p <0030). Conclusions: The factors associated with frailty suggest a predictive model helping to understand the syndrome, guiding actions that minimize adverse effects on the aging process
