A prospective evaluation of inter-rater agreement of routine medical records audits at a large general hospital in São Paulo, Brazil.

BACKGROUND: The quality of patient medical records is intrinsically related to patient safety, clinical decision-making, communication between health providers, and continuity of care. Additionally, its data are widely used in observational studies. However, the reliability of the information extracted from the records is a matter of concern in audit processes to ensure inter-rater agreement (IRA). Thus, the objective of this study is to evaluate the IRA among members of the Patient Health Record Review Board (PHRRB) in routine auditing of medical records, and the impact of periodic discussions of results with raters. METHODS: A prospective longitudinal study was conducted between July of 2015 and April of 2016 at Hospital Municipal Dr. Moysés Deutsch, a large public hospital in São Paulo. The PHRRB was composed of 12 physicians, 9 nurses, and 3 physiotherapists who audited medical records monthly, with the number of raters changing throughout the study. PHRRB meetings were held to reach a consensus on rating criteria that the members use in the auditing process. A review chart was created for raters to verify the registry of the patient's secondary diagnosis, chief complaint, history of presenting complaint, past medical history, medication history, physical exam, and diagnostic testing. The IRA was obtained every three months. The Gwet's AC1 coefficient and Proportion of Agreement (PA) were calculated to evaluate the IRA for each item over time. RESULTS: The study included 1884 items from 239 records with an overall full agreement among raters of 71.2%. A significant IRA increase of 16.5% (OR = 1.17; 95% CI = 1.03-1.32; p = 0.014) was found in the routine PHRRB auditing, with no significant differences between the PA and the Gwet's AC1, which showed a similar evolution over time. The PA decreased by 27.1% when at least one of the raters was absent from the review meeting (OR = 0.73; 95% CI = 0.53-1.00; p = 0.048). CONCLUSIONS: Medical record quality has been associated with the quality of care and could be optimized and improved by targeted interventions. The PA and the Gwet's AC1 are suitable agreement coefficients that are feasible to be incorporated in the routine PHRRB evaluation process.

Fasting glucose of patients from public health care in the southern region of São Paulo: correlation with glycated hemoglobin and lipid levels. / Glicemia de jejum de pacientes da rede pública de saúde na região sul de São Paulo: correlação com hemoglobina glicada e níveis lipídicos.

INTRODUCTION: Fasting glucose is a test used for monitoring diabetes mellitus, as well as its screening and diagnosis. The objective of this study was to evaluate fasting glucose results and their correlation with glycated hemoglobin and lipids. METHODS: Cross-sectional study, involving 77,581 patients, attended in 2014. RESULTS: The majority of the patients are women (65%). The age of the patients ranged from 18 to 115 years (mean of 53 ± 15.5). The agreement between fasting glucose and glycated hemoglobin was moderate (kappa = 0.416); however, it was substantial for the levels used for the diagnosis of diabetes (kappa = 0.689) and poor for pre-diabetes (kappa = 0.188). Fasting glucose ≥ 100 mg/dL was observed in 41.1% of the patients and 61.5% present glycated hemoglobin ≥ 5.7%. Lipid abnormalities are likeliest in patients with elevated fasting glucose. From those 14,241 individuals that had fasting glucose ≥ 126 mg/dL, the microalbuminuria test was performed in only 883 (6.2%) patients, with abnormal results in 201 (22.8%). CONCLUSIONS: The high frequency of fasting glucose with abnormal results may reflect the high proportion of exams performed by individuals with diagnosis of diabetes, to evaluate their glycemic control. The low frequency of requests for microalbuminuria tests in those with probable diagnosis of diabetes reflects the little attention paid for the screening of chronic complications of diabetes. It calls attention the high frequency of dyslipidemia in those individuals, highlighting the fact that this is a population with high cardiovascular risk.

INTRODUÇÃO: A glicemia de jejum é um teste usado para o monitoramento do diabetes mellitus, bem como para seu rastreamento e diagnóstico. O objetivo do estudo foi analisar resultados de glicemia de jejum de pacientes da rede pública e sua correlação com hemoglobina glicada e lipídios. MÉTODOS: Estudo transversal, com 77.581 pacientes, atendidos em 2014. RESULTADOS: A maioria é do sexo feminino (65%), com idade entre 18 e 115 anos (53 ± 15,5 anos). A concordância entre glicemia de jejum e hemoglobina glicada foi moderada (Kappa = 0,416), entretanto foi substancial para níveis compatíveis com diabetes (Kappa = 0,689) e pobre para pré-diabetes (Kappa = 0,188). Glicemia de jejum ≥ 100 mg/dL foi encontrada em 41,1% dos pacientes e hemoglobina glicada ≥ 5,7% em 61,5%. As alterações lipídicas são mais frequentes nos indivíduos com alterações na glicemia. Dos 14.241 indivíduos com glicemia de jejum ≥ 126 mg/dL, a microalbuminúria foi pesquisada em apenas 883 (6,2%) indivíduos, com resultado alterado em 201 (22,8%). CONCLUSÕES: Nos indivíduos que realizaram mais de uma dosagem de glicemia de jejum, a maioria permaneceu com exames alterados, principalmente os que apresentavam valores compatíveis com o diagnóstico de diabetes, sugerindo que não conseguem um controle adequado. A baixa frequência de pesquisa de microalbuminúria em indivíduos com glicemia de jejum sugestiva de diabetes reflete a pequena preocupação com o rastreio de suas complicações crônicas. A elevada frequência de dislipidemia nesses indivíduos evidencia ser uma população de elevado risco cardiovascular.

Barriers and Benefits in Telemedicine Arising Between a High-Technology Hospital Service Provider and Remote Public Healthcare Units: A Qualitative Study in Brazil.

BACKGROUND: In Brazil, the Program for Institutional Development of the Unified Healthcare System (PROADI-SUS) has implemented a telemedicine service for urgent situations and emergencies. It is delivered by a high-technology (HT) hospital to 15 remote healthcare units (RUs) in 11 different Brazilian states. The aim of this study was to investigate possible barriers and benefits in telemedicine service among these units. MATERIALS AND METHODS: We performed a qualitative study on the perceptions of physicians involved in telemedicine service in their role as providers and consultants. An individual, semistructured recorded interview was conducted with 28 physicians (17 HT; 11 RU) encompassing telemedicine resources and interaction among HT and RU physicians. Data analysis was performed by Discourse of Collective Subject. RESULTS: We identified the following barriers in the telemedicine service: (1) lack of experience in the use of technology or the quality of the internet signal; (2) the multiplicity of different telemedicine platforms; (3) the quality of the image sent to the HT hospital; (4) the misunderstanding that telemedicine is a time-consuming technology instead of a resource that may help to save lives; (5) not feeling comfortable exposing doubts to other HT colleagues; (6) problems in the management of telemedicine use in the RUs; and (7) political and legal issues. However, important benefits in telemedicine service were also described. CONCLUSIONS: The structural barriers should be the target of hospital managers. Development of standard remote care protocols may increase the use of telemedicine and create new work routines. Given the relationship difficulties among the RU and HT doctors during telemedicine consultations, other meetings should be organized to allow more interpersonal interactions. These meetings may also have the goal of sharing outcome indicators of their joint activity in telemedicine to stimulate and make them aware of the benefits of their interaction.

Implementation of integration strategies between primary care units and a regional general hospital in Brazil to update and connect health care professionals: a quasi-experimental study protocol.

BACKGROUND: Better communication among field health care teams and points of care, together with investments focused on improving teamwork, individual management, and clinical skills, are strategies for achieving better outcomes in patient-oriented care. This research aims to implement and evaluate interventions focused on improving communication and knowledge among health teams based on points of care in a regional public health outreach network, assessing the following hypotheses: 1) A better-working communication process between hospitals and primary health care providers can improve the sharing of information on patients as well as patients' outcomes. 2) A skill-upgrading education tool offered to health providers at their work sites can improve patients' care and outcomes. METHODS/DESIGN: A quasi-experimental study protocol with a mixed-methods approach (quantitative and qualitative) was developed to evaluate communication tools for health care professionals based in primary care units and in a general hospital in the southern region of São Paulo City, Brazil. The usefulness and implementation processes of the integration strategies will be evaluated, considering: 1) An Internet-based communication platform that facilitates continuity and integrality of care to patients, and 2) A tailored updating distance-learning course on ambulatory care sensitive conditions for clinical skills improvements. The observational study will evaluate a non-randomized cohort of adult patients, with historical controls. Hospitalized patients diagnosed with an ambulatory care sensitive condition will be selected and followed for 1 year after hospital discharge. Data will be collected using validated questionnaires and from patients' medical records. Health care professionals will be evaluated related to their use of education and communication tools and their demographic and psychological profiles. The primary outcome measured will be the patients' 30-day hospital readmission rates. A sample size of 560 patients was calculated to fit a valid logistic model. In addition, qualitative approaches will be used to identify subjective perceptions of providers about the implementation process and of patients about health system use. DISCUSSION: This research project will gather relevant information about implementation processes for education and communication tools and their impact on human resources training, rates of readmission, and patient-related outcomes.

Effect of an Educational Program on Schoolchildren's Energy Expenditure during Physical Education Classes / Efeito de um programa de educação no gasto energético de escolares durante as aulas de educação física

OBJECTIVE: Physical activity is a means of prevention of noncommunicable diseases. The level of physical activity of children is decreasing in Brazil, and this can increase the risks of diseases associated with sedentary lifestyles and obesity. METHOD: This is a school-based randomized controlled trial which evaluated the impact of an educational intervention on children's physical activity level, energy expenditure, and teacher's behavior during physical education classes at public schools in São Paulo. The studied population comprised children attending the 1st and the 2nd grades of eight schools (three exposed and five unexposed to teacher training on a course in nutrition and physical activity). Outcomes were measured by direct observation, recorded by a VHS camera during physical education classes; data from 78 physical education classes were analyzed by the System for Observing Fitness Instruction Time - SOFIT. RESULTS: After intervention, results showed highly significant increases in children's physical activity level (walking, p < 0.001; vigorous activities (p < 0.001), and a decrease in the standing category (p < 0.001). It also showed a nonsignificant increase in mean energy expenditure of children (70.6% = 27.6Kcal), but the interaction's effect of group and time (intervention) was highly significant (32.4Kcal; 95%CI 24.7 - 40.1, p < 0.001) indicating the intervention effectiveness in increasing the energy expenditure of children during Physical Education classes. It also showed an increase in length of physical education classes (26.2 to 32.1 minutes (p = 0.01). CONCLUSION: There was a change in teachers' behavior with a positive impact on children's physical activity level and energy expenditure after the educational intervention.

OBJETIVO: A prática de atividade física é uma forma de prevenção de doenças não transmissíveis. O nível de atividade física das crianças tem diminuído no Brasil, fato que pode contribuir para o aumento do risco de doenças associadas com o sedentarismo e a obesidade. MÉTODO: Este é um ensaio educacional randomizado controlado que avaliou o impacto de uma intervenção educacional para professores no nível de atividade física e no gasto energético das crianças, e no comportamento do professor durante as aulas de educação física em escolas públicas de São Paulo. A população estudada compreendeu crianças de 1ᵃ e 2ᵃ series de oito escolas (três expostas e cinco não-expostas ao treinamento de professores em nutrição e atividade física). Os resultados foram medidos por observação direta e gravados por uma câmera VHS durante as aulas de educação física. Dados de 78 aulas de educação física foram analisados segundo o System for Observing Fitness Instruction Time - SOFIT. RESULTADOS: Após intervenção, os resultados mostraram aumentos significantes no nível de atividade física das crianças (caminhada, p < 0.001; atividades vigorosas (p < 0.001), e diminuição na categoria na qual a criança permanecia em pé (p < 0.001)). No entanto, os resultados mostraram um aumento não-significante na média do gasto energético pelas crianças (70.6% = 27.6Kcal), porém a interação do grupo e do tempo (intervenção) foi altamente significante (32.4Kcal; 95% CI 24.7; 40.1, p < 0.0001) indicando a efetividade da intervenção em aumentar o gasto energético das crianças durante a aulade educação física. Os resultados mostraram também um aumento na duração da aula de educação física (26.2 para 32.1 minutos (p = 0.01). CONCLUSÃO: Houve diferença no comportamento dos professores com um impacto positivo no nível de atividade física e no gasto energético das crianças após a intervenção educacional.

Determining workload and size of nursing team in the pediatric emergency department.

OBJECTIVE: To identify indicators of required nursing workload for pediatric patients care in an emergency department. METHODS: This cross-sectional quantitative study was carried out in a pediatric short-stay unit at a public hospital in São Paulo (SP), Brazil. The patient classification system and activity times of nursing care proposed by the Brazilian Federal Nurse Council were applied to all patients admitted over a 1-month period. The instruments were applied by two nurses in populations of 500 and 453 patients, respectively. Nursing workload was calculated in terms of hours and by nurse/patient ratio. Data were analyzed by descriptive statistics, and inter- and intraobserver reliability was assessed by using Kappa coefficient. Confidence intervals were measured to verify differences in numbers of patient among work shifts. RESULTS: The average daily workload was 108.7 hours and the average amount of time spent on nursing care per patient was 7.9 hours. The nurse-patient ratio was 1:2.6. CONCLUSION: The application of the standardized classification instrument was adequate. It enabled the classification of pediatric patients and the measurement of amount of time needed for nursing care. The average number of nursing work hours per patient met the average time for semi-intensive care established by the Brazilian Federal Nurse Council.

Physical activity counseling in primary health care in Brazil: a national study on prevalence and associated factors.

BACKGROUND: The aim of this study was to determine the prevalence and correlates of physical activity counseling among physicians and nurses working in primary health care in Brazil. METHODS: A phone survey was carried out in 2011 with professionals working in primary health care in Brazil. The target sample consisted of 1,600 randomly selected primary care units covering all regions of the country. We successfully interviewed 529 professionals within the sampled units; 182 physicians and 347 nurses. The overall response rate was 49.6%. Multivariable logistic regression was used to estimate correlates of counseling in the whole sample and separately for physicians and nurses. RESULTS: The prevalence of regular physical activity counseling for at least six months was 68.9% (95% CI 64.9; 72.8) and was significantly higher among physicians compared to nurses (p < 0.05). Most professionals (93.2%) interviewed were unfamiliar with current physical activity recommendations for health. In the adjusted analysis, physical activity counseling was more frequent among those who report assessing patient's physical activity (OR = 2.16; 95% CI 1.41; 3.29), those reporting that lack of time was not a barrier for counseling (OR = 0.62 95% CI 0.42-0.93), those who felt prepared to provide physical activity counseling (OR = 2.34; 95% CI 1.50-3.66), and those working at primary care units offering physical activity programs for patients (OR = 2.06; 95% CI 1.33-3.20). In the stratified analysis, only assessing patient's physical activity was a significant correlate among physicians whereas assessing patient's physical activity, feeling prepared to provide counseling and working in units with physical activity interventions were significant correlates among nurses. CONCLUSIONS: Physicians and nurses deemed physical activity counseling of great importance in primary health care in Brazil. However, in order to increase the quality of counseling and the number of professionals engaging in this activity, these health teams require greater knowledge about physical activity (global recommendations for health) as well as training on the application of instruments for assessing physical activity. Moreover, sufficient time must be allowed during consultations for the counseling process, and physical activity promotion programs should be implemented within the primary health care units.

Changes in adiposity levels in schoolchildren according to nutritional status: analysis over a 30-year period / Modificações da adiposidade em escolares de acordo com o estado nutricional: análise de 30 anos

The aim of this study was to analyze changes in adiposity levels over a 30-year period in schoolchildren according to nutritional status. This study is part of Projeto Misto Longitudinal de Crescimento, Desenvolvimento e Aptidão Física de Ilhabela. 1.144 schoolchildren of both sexes, aged between 10 and 11 years, met the following inclusion criteria: (a) have at least one complete evaluation in one of the analyzed periods; (b) be in the prepubertal stage of sexual maturation; and (c) be apparently healthy. Analyzed periods were 1978/1980 (Baseline), 1988/1990 (10 years), 1998/2000 (20 years), 2008/2010 (30 years). Analyzed variables were: body mass (kg), height (cm) and adiposity levels (mm). Children were classified into three categories: eutrophic, overweight and obese, according to nutritional status, using World Health Organization (WHO) body mass index (BMI) curves for age and sex. For a comparison between periods, Two-Factor Analysis of Variance and Bonferroni's test were used. In both sexes, the most significant increase in adiposity levels occurred among the eutrophic group, followed by the overweight group and obese group. Results showed an increase in adiposity levels over a 30-year period, even with nutritional status control. It shows that individuals with a similar BMI may vary in proportion and distribution of subcutaneous adipose tissue.

O objetivo do estudo foi analisar as modificações da adiposidade de escolares, durante 30 anos, de acordo com o estado nutricional. O estudo faz parte do "Projeto Misto Longitudinal de Crescimento, Desenvolvimento e Aptidão Física de Ilhabela". Uma amostra de 1.144 escolares de ambos os sexos, de 10 e 11 anos, atenderam aos seguintes critérios de inclusão: (a) pelo menos uma avaliação completa em um dos períodos analisados; (b) estar no estágio pré-púbere de maturação sexual; (c) ser aparentemente saudável. Os períodos analisados foram 1978/1980 (linha de base), 1988/1990 (10 anos), 1998/2000 (20 anos), 2008/2010 (30 anos). As variáveis analisadas foram: massa corporal, estatura e adiposidade, pela análise individual de cada dobra cutânea. Os indivíduos foram classificados em eutróficos, excesso de peso e obesos, mediante as curvas propostas pela Organização Mundial da Saúde (OMS) de índice de massa corporal para idade e sexo. Para comparar os períodos, foi utilizada a Análise de Variância com Dois Fatores seguida pelo método Bonferroni. Em ambos os sexos, o maior aumento significante ocorreu no grupo de escolares eutróficos, seguido pelos grupos excesso de peso e obeso. Houve modificações da adiposidade, mesmo com o controle do estado nutricional, durante o período de 30 anos analisado, mostrando que os indivíduos que têm semelhantes índices de massa corporal podem variar em proporção e distribuição de tecido adiposo subcutâneo.

Aptidão cardiorrespiratória e estado nutricional de escolares: evolução em 30 anos / Cardiorespiratory fitness and nutritional status of schoolchildren: 30-year evolution

OBJETIVO: Comparar as mudanças da aptidão cardiorrespiratória em avaliações a cada 10 anos a partir de 1978/1980, de acordo com o estado nutricional e o sexo de escolares do município de Ilhabela, Brasil. MÉTODOS: O estudo faz parte do Projeto Misto-Longitudinal de Crescimento, Desenvolvimento e Aptidão Física de Ilhabela. Participaram do estudo 1.291 escolares de ambos os sexos, de 10 e 11 anos de idade. Os períodos analisados foram 1978/1980, 1988/1990, 1998/2000 e 2008/2010. As variáveis analisadas foram peso corporal, estatura e aptidão cardiorrespiratória (VO2máx - L.min-1 e mL.kg-1.min-1) realizada por um protocolo progressivo submáximo em um ciclo ergômetro. Os indivíduos foram classificados em eutróficos e excesso de peso mediante as curvas propostas pela Organização Mundial da Saúde de índice de massa corporal para idade e sexo. Para comparar os períodos, foi utilizado a ANOVA com três fatores, seguida pelo método Bonferroni. RESULTADOS: A quantidade de eutróficos (61%) foi maior do que a de excesso de peso. Houve diminuição significativa da aptidão cardiorrespiratória em ambos os sexos. Entre os escolares meninos e as meninas eutróficas houve diminuição de 22% e 26%, respectivamente. Nos escolares com excesso de peso, os meninos diminuíram em 12,7%, e as meninas, em 18%. CONCLUSÃO: Em uma análise de 30 anos, com avaliações a cada 10 anos a partir de 1978/1980, houve uma diminuição significante da aptidão cardiorrespiratória em escolares de ambos os sexos, que não pode ser explicada pelo estado nutricional. A queda da aptidão cardiorrespiratória foi maior nos escolares eutróficos do que nos obesos.

OBJECTIVE: To compare the changes in cardiorespiratory fitness in evaluations performed every ten years since 1978/1980, according to the nutritional status and gender of students in the city of Ilhabela, Brazil. METHODS: The study is part of the Mixed Longitudinal Project on Growth, Development and Physical Fitness of Ilhabela. The study included 1,291 students of both genders, aged 10 to 11 years old. The study periods were: 1978/1980, 1988/1990, 1998/2000, and 2008/2010. The variables analyzed were: body weight, height, and cardiorespiratory fitness (VO2max -L.min-1 and mL.kg-1.min-1) performed using a submaximal progressive protocol on a cycle ergometer. Individuals were classified as normal weight and overweight according to curves proposed by the World Health Organization of body mass index for age and gender. Analysis of variance (ANOVA) with three factors followed by the Bonferroni method were used to compare the periods. RESULTS: The number of normal weight individuals (61%) was higher than that of overweight. There was a significant decrease in cardiorespiratory fitness in both genders. Among the schoolchildren with normal weight, there was a decrease of 22% in males and 26% in females. In overweight schoolchildren, males showed a decrease of 12.7% and females, of 18%. CONCLUSION: During a 30-year analysis with reviews every ten years from 1978/1980, there was a significant decrease in cardiorespiratory fitness in schoolchildren of both genders, which cannot be explained by the nutritional status. The decline in cardiorespiratory fitness was greater in individuals with normal weight than in overweight individuals.

Padrões alimentares de adolescentes na cidade de São Paulo / Eating patterns of eutrophic and overweight adolescents in the city of São Paulo, Brazil

OBJETIVO: Identificar os padrões alimentares de adolescentes eutróficos e com excesso de peso. MÉTODOS: Estudo transversal envolvendo 239 adolescentes de ambos os sexos, na faixa etária de 14 a 19 anos, alunos de uma escola pública da cidade de São Paulo, Brasil. Foram coletados dados antropométricos e registro alimentar de 4 dias. O estado nutricional foi avaliado pelo índice de massa corporal de acordo com os critérios de Must et al., e foi aplicada análise fatorial para a identificação dos padrões alimentares. RESULTADOS: Foram identificados quatro padrões alimentares: tradicional, urbano, saudável e junk food. O estado nutricional de eutrofia teve associação positiva com os padrões tradicional e urbano, o sobrepeso com os padrões saudável e junk food, e a obesidade associou-se negativamente com os padrões urbano, saudável e junk food. CONCLUSÃO: O padrão saudável foi encontrado entre os adolescentes com sobrepeso, evidenciando preocupação com o controle do peso e tentativa de mudança do hábito alimentar. Entre os obesos, a ocorrência do sub-relato provavelmente tenha influenciado o resultado das associações.

OBJECTIVE: This study identified the dietary patterns of normal weight and overweight adolescents. METHODS: This was a cross-sectional study of 239 adolescents from a public school in São Paulo, Brazil; of both sexes, aged 14 to 19 years. Anthropometric data and 4-day dietary records were collected. Nutritional status was assessed by body mass index, according to the criteria established by Must et al. Factor analysis was used to identify dietary patterns. RESULTS: This assessment resulted in the identification of four dietary patterns: Traditional, Urban, Healthy, and Junk Food. Normal weight was positively associated with the Traditional and Urban patterns, and overweight was positively associated with the Healthy and Junk Food patterns. Lastly, obesity was negatively associated with the Urban, Healthy and Junk Food patterns. CONCLUSION: The Healthy pattern was found among overweight adolescents who were concerned with weight control and trying to change eating habits. Among the obese, the occurrence of underreporting probably influenced the outcome of the associations.

Avaliação da tecnologia empregada no Hemoglobinômetro Hb-010 (Agabê®) e a possibilidade de aplicação no Sistema Único de Saúde / Evaluation of the Technology Employed in the Hb-010 Hemoglobinmeter (Agabê®) and the possibility of its application in the Sistema Único de Saúde

O objetivo deste artigo é descrever o processo de avaliação da utilização de hemoglobinometria de resultado imediato em diferentes regiões e cenários do Sistema Único de Saúde, utilizando hemoglobinômetro portátil, de tecnologia nacional. Como metodologia, após validação do hemoglobinômetro em campo, contra equipamentos validados de bancada e portátil, em sangue venoso e periférico, foram realizadas avaliações da utilização do equipamento em unidades básicas de saúde tradicional e de saúde da família, na cidade de São Paulo. Foram realizadas avaliações sob a forma de campanhas em Ilhabela (SP), Santa Luzia do Itanhi (SE), Afuá (PA) e Macapá (AP). Em todas as localidades foram realizadas medições diagnósticas, prescrito e fornecido sulfato ferroso aos anêmicos, com monitoramento na metade e ao final do tratamento de 12 semanas. As prevalências e taxas de recuperação de anemia encontradas foram 26,4% e 78,9%; 22,4% e 79%; e 54% e 60%, respectivamente. Conclui-se que a utilização de hemoglobinometria imediata com equipamento nacional de baixo custo gerou agilidade no diagnóstico e tratamento, com taxas de recuperação similares em diferentes regiões do país

Evolução no nível de atividade física de escolares observados pelo período de 1 ano / Evolution in the physical activity level of school children observed during 1 year

O presente estudo teve como objetivo avaliar o nível de atividade física (NAF) entre escolares de diferentes estadosnutricionais, matriculados nas 1ª e 2ª séries de 8 escolas públicas estaduais da cidade de São Paulo, após 1 ano deobservação. A amostra foi composta de 1434 crianças de ambos os sexos (49,3% do sexo masculino; 50,7% do sexo feminino), na faixa etária de 7 a 9 anos (x: 7,5 + 0,5 anos). Para a avaliação do estado nutricional foi utilizado o índice peso/estatura (P/E) e adotados os seguintes pontos de corte:eutrofia entre –1Z e +1Z; obesidade acima de 2Z; sobrepeso entre 1Z e 2Z; desnutrição abaixo de –1Z. ONAF foi mensurado por meio de questionário de autopreenchimento,respondido pelos pais das crianças. A partir dos dados do questionário foi elaborado um Score de Atividade Física (SAF), que serviu como referência para a mensuração do NAF. Na análise estatística utilizou-se metodologia de modelos lineares generalizados, comequações generalizadas de estimação (GEE – Generalized Estimation Equation), sendo adotado como nível designificância p £ 0,05.
