Avaliação mecânica in vitro utilizando miniplacas quadradas e retangulares do sistema 2.0 mm em fraturas da região anterior de mandíbula

The aim of this study was to comparatively evaluate the mechanical strength of squared and rectangular 2.0 mm system miniplates comparing them to the standard configuration with 2 straight miniplates in stabilizing fractures in the anterior mandible. Ninety synthetic polyurethane mandible replicas were used in mechanical test. The samples were divided into six groups of three different methods for fixation. Groups 1, 2 and 3 showed complete fractures in symphysis, characterized by a linear separation between the medial incisor, and groups 4, 5 and 6 showed complete fractures in parasymphysis with oblique design. Groups 1 and 4 were represented by the standard technique with two straight miniplates parallel to each other. Groups 2 and 5 were stabilized by squared miniplates and groups 3 and 6 were fixed by rectangular design. Each group was subjected to a mechanical test at a displacement speed of 10 mm/min on a universal testing machine, receiving linear vertical load on the region of the left first molar. The values of the maximum load and when displacements reached 5 mm were obtained and statistically analyzed by calculating the confidence interval of 95%. Fixation systems using squared (G2) and rectangular (G3) miniplates obtained similar results. No statistically significant differences with respect to the maximum load and the load at 5 mm displacement were found when compared to standard method in symphyseal fractures (G1). In parasymphysis the fixation method using squared miniplates (G5) obtained results without significant differences regarding the maximum load and the load at 5 mm when compared to the standard configuration (G4). The fixation method using rectangular miniplates (G6) showed inferior results which were statistically significant when compared to the standard configuration (G4) for parasymphysis fractures. The mechanical behavior of the fixation methods was similar, except when rectangular miniplates were used. The fixation methods showed better results with statistical significance in symphyseal fractures

A relação entre os determinantes sociais em saúde e os investimentos setoriais e a mortalidade infantil em municípios brasileiros com mais de 80 mil habitantes

Investments in health have controversial influence on results of the health of populations, besides being subject rarely explored in literature. Moreover, from the 1970s, the social determinants of health have been consolidated in the disease process as multifactorial factors (social, economic, cultural, etc.) that directly or indirectly influence the occurrence of health problems of populations, as well as mortality rates. This study aimed to evaluate the influence of these investments and the social determinants of health on infant mortality and its neonatal and post-neonatal mortality. This is an ecological study, in which the sample was composed of Brazilians cities with over 80,000 inhabitants, avoiding fluctuations in mortality rates for common small populations, and ensure greater coverage of information systems on mortality and births Brazilians and, therefore, increase data consistency. To isolate the effect of investments in health, we used multiple linear regression. The socioeconomic indicators (p <0.001, p = 0.004, p <0.001), the inequality index (p <0.001, p = 0.001, p = 0.006) and coverage of prenatal visits (p <0.001, p <0.001; p = 0.005) were associated with infant mortality rate total, neonatal and post-neonatal, and the Gross Domestic Product per capita only influenced the overall infant mortality rate and neonatal (p=0.022; 0.045). Investments in health, in this model, lost statistical significance, showing no correlation with mortality rates among children under one year. We conclude that the social determinants of health has an influence on the variation in mortality rates of Brazilian cities, however the same was not observed for indicators of health investment

Impacto da cárie precoce severa na infância na qualidade de vida relacionada à saúde bucal de pré-escolares sob privação social

Early childhood caries, especially in its severe form, which is characterized by an acute and aggressive nature, can have negative impacts on thequality of life of a child, due to effects such as difficulty in chewing, decreased appetite, weight loss, insomnia, changes in behavior and a decreased performance in school, among others. Moreover, the quality of life of the child`s family can also be affected, as the pain and discomfort caused by this type of caries result in loss of working days of parents, spending on dental treatments, changes in sleep patterns and stress. The aim of this study was to evaluate the impact of severe early childhood caries in the Oral Health-Related Quality of Life (OHRQoL) of public daycares`s preschool children through the Escala de Impacto da Saúde Bucal na Primeira Infância, a Brazilian version of the Early Childhood Oral Health Impact Scale (ECOHIS). A single calibrated examiner (kappa=1.0) evaluated, through the dmfs index, the oral health of 116 children aged between 3 and 5, which were included in one of three study groups: "caries-free", "not-severe early childhood caries" and "severe early childhood caries". The parents responded to ECOHIS, to assess their perception regarding the OHRQoL of their children, and a questionnaire on socioeconomic conditions. The OHRQoL was measured through the total scores and domains of ECOHIS. Descriptive analysis, Mann-Whitney test, Kruskal-Wallis test, chi-square test and Poisson multiple regression with robust variance were used. Among the children observed, 38.8% were caries-free, 27.6% showed not-severe early childhood caries and 33.6% showed severe early childhood caries. Regarding the total score of ECOHIS, severe early childhood caries had a greater negative impact on OHRQoL, compared to caries-free and not-severe early childhood caries groups (p <0.001). Regarding the child subscale, there was significant difference between the "severe early childhood caries" group and the other groups in all domains, except for theone of self-image / social interaction. In the family subscale domains, there was statistical significance between the severe early childhood caries and the caries-free groups in all domains (p <0.001), whereas between the "severe early childhood caries and not-severe early childhood caries groups there was a statistically significant difference only in the domain of parental anguish (p <0.001). Multivariate analysis showed that early childhood caries and the parent`s age were significantly associated to OHRQoL (p <0.05), independently of the other variables in the model. The presence of severe early childhood caries resulted in greater negative impact on OHRQoL (AdjPR= 6.016; 95%CI = 3.12 11.56; p<0.001), while older parents reported better OHRQoL (AdjPR = 0.603; 95%CI = 0.428 - 0.850; p = 0.004). The presence of severe early childhood caries had a negative impact on OHRQoL of preschool children and their families.

Prevalência de incontinência urinária e fatores associados em idosos institucionalizados

Urinary incontinence (UI) is a geriatric syndrome that is especially prevalent in institutionalized individuals, and that causes economic and social impacts derived from treatment costs and overload of caregiver. UI also entails physical consequences to the health of the elderly, such as urinary tract infections or pressure ulcers, among other health problems. However, the existing national research on this condition is still scarce and comprises serious methodological biases. Therefore, the objective of this study is to determine the prevalence of urinary incontinence and associated factors in institutionalized elderly. A cross-sectional study is presented herein, conducted between October and December, 2013 and carried out in 10 nursing homes in the city of Natal (Northeast Brazil). UI was verified through the program Minimum Data Set version 3.0, which was also used to assess fecal incontinence, urinary devices and UI control programs. Data collection included sociodemographic information, UI characterization, as well as variables related to the institution itself and to health conditions (comorbidities, medication, pelvic floor surgery, Barthel Index for functional capacity and Pfeiffer test for cognitive status). Bivariate analysis was performed using the Chi-Square Test (or Fisher‟s Exact Test) and the Linear Chi-Square Test, calculating the prevalence ratio with 95% confidence interval. Variables with p value under 0.20 were included in the multivariate analysis, which was performed using the Stepwise Forward logistic regression. The inclusion of variables in the final model depended on the likelihood ratio test, absence of multicollinearity and on the Hosmer-Lemeshow test. A statistical significance level of 0.05 was considered. Six (1.8%) hospitalized elderly, one individual in palliative care (0.3%) and one (0.3%) individual under the age of 60 were excluded from the study. The final sample consisted of 321 elderly, mostly females, with a mean age of 81.5 years. The prevalence of UI was 59.43% and the final model revealed statistically a significant association between UI and white race, physical inactivity, stroke, mobility constraints and cognitive decline. The most frequent UI type was functional UI due to physical or cognitive disability, and incontinence control measures were applied only to a minority of residents (approximately 8%). It is concluded that UI is a health issue that affects more than half of the institutionalized elderly, and is associated with white race, physical inactivity, stroke and other geriatric syndromes such as immobility and cognitive disability. Most of these associated factors are modifiable and therefore the findings of this study highlight the importance of UI prevention and treatment in nursing homes, which include general measures, such as physical and psychosocial activities, and specific measures, such as prompted voiding

Textura do recurso pedagógico e implicações em atividade de encaixe realizada por indivíduos com paralisia cerebral

O estudo teve o propósito de verificar a influência da textura do recurso pedagógico no tempo despendido e no índice de retidão para execução de uma atividade de encaixe realizada por indivíduos com paralisia cerebral. Participaram do estudo 6 alunos com sequelas de paralisia cerebral do tipo espástica, com idade entre 7 anos e 8 meses e 28 anos e 1 mês. O participante deveria segurar o objeto e levá-lo a um ponto demarcado previamente para o encaixe e, após, retorná-lo à posição inicial. O objeto foi apresentado nas texturas lisa, intermediária e áspera, de forma aleatória. Para a coleta de dados, foi utilizada filmagem para posterior leitura pelo programa Kavideo, que possibilitou cálculos para observar o tempo despendido na tarefa e o índice de retidão. Foi realizado o estudo da normalidade das distribuições, verificada por meio do teste de normalidade de Kolmogorov-Smirnov (Teste KS) e a comparação entre as texturas lisa, intermediária e áspera, no movimento de encaixe, por meio da análise de variância de medidas repetidas. Adotou-se para todos os testes nível de significância de 5% de probabilidade para a rejeição da hipótese de normalidade. O resultado do teste de análise de variância de medidas repetidas mostrou que não houve significância para as variáveis estudadas com o recurso apresentado nas três texturas. Porém, os dados da estatística descritiva mostraram que o encaixe do recurso com a textura lisa despendeu um menor tempo para execução da tarefa e, também, determinou um melhor desempenho com relação à trajetória do movimento.

Contrastes e contrastes encobertos na produção da fala de crianças

TEMA: análise acústica da fala. OBJETIVO: analisar acusticamente as substituições envolvendo o contraste entre /t/ e /k/ na fala de crianças em aquisição típica e desviante do contraste acima referido, a fim de identificar e quantificar a existência de contrastes encobertos. MÉTODO: foi elaborado um experimento de produção de fala que envolveu a repetição de palavras, que combinavam /t/ e /k/ com /a/ e /u/ na posição acentuada, por 9 crianças divididas em três grupos: crianças em processo de aquisição do contraste investigado (G1); crianças com transtorno fonológico (G2) e crianças com produções típicas (G3). Com o uso do software Praat, as produções foram editadas e analisadas de acordo com os seguintes parâmetros acústicos: características espectrais do burst; transição CV e características temporais. Os testes estatísticos utilizados foram ANOVA de Friedman e Manova. A significância estatística adotada foi menor que 0,05. RESULTADOS: tanto nas produções das crianças do G2 quanto nas produções das crianças do G1, detectamos, em grande medida (80% e 57,4%, respectivamente), a presença de contrastes encobertos nos erros de substituição das oclusivas investigadas. Adicionalmente, a análise acústica revelou diferenças em como as crianças utilizam as pistas fonético-acústicas para marcarem a distinção entre /t/ e /k/. CONCLUSÃO: muitas das substituições presentes da produção de fala de crianças em processo de aquisição típico e desviante tratam-se na verdade de contrastes fônicos encobertos. Além disso, o uso da análise acústica permitiu a detecção de diferenças sutis da produção da fala das crianças.

Nasoendoscopy of velopharynx before and during diagnostic therapy

Nasoendoscopy is an important tool for assessing velopharyngeal function. The purpose of this study was to analyze velar and pharyngeal wall movement and velopharyngeal gap during nasoendoscopic evaluation of the velopharynx before and during diagnostic therapy. Nasoendoscopic recordings of 10 children with operated cleft lip and palate were analyzed according to the International Working Group Guidelines. Ratings of movement of velum and pharyngeal walls, and size, location and shape of gaps were analyzed by 3 speech-language pathologists (SLPs). Imaging was obtained during repetitions of the syllable /pa/ during a single nasoendoscopic evaluation: (a) before diagnostic therapy, and (b) after the children were instructed to impound and increase intraoral air pressure (diagnostic therapy). Once the patients impounded and directed air pressure orally, the displacement of the velum, right, left and posterior pharyngeal walls increased 40, 70, 80, and 10%, respectively. Statistical significance for displacement was found only for right and left lateral pharyngeal walls. Reduction in gap size was observed for 30% of the patients and other 40% of the gaps disappeared. Changes in gap size were found to be statistically significant between the two conditions. In nasoendoscopic assessment, the full potential of velopharyngeal displacement may not be completely elicited when the patient is asked only to repeat a speech stimulus. Optimization of information can be done with the use of diagnostic therapy's strategies to manipulate VP function. Assuring the participation of the SLP to conduct diagnostic therapy is essential for management of velopharyngeal dysfunction.

Avaliação da contribuição de desenvolvedores para projetos de software usando mineração de repositórios de software e mineração de processos

Software Repository Mining (MSR) is a research area that analyses software repositories in order to derive relevant information for the research and practice of software engineering. The main goal of repository mining is to extract static information from repositories (e.g. code repository or change requisition system) into valuable information providing a way to support the decision making of software projects. On the other hand, another research area called Process Mining (PM) aims to find the characteristics of the underlying process of business organizations, supporting the process improvement and documentation. Recent works have been doing several analyses through MSR and PM techniques: (i) to investigate the evolution of software projects; (ii) to understand the real underlying process of a project; and (iii) create defect prediction models. However, few research works have been focusing on analyzing the contributions of software developers by means of MSR and PM techniques. In this context, this dissertation proposes the development of two empirical studies of assessment of the contribution of software developers to an open-source and a commercial project using those techniques. The contributions of developers are assessed through three different perspectives: (i) buggy commits; (ii) the size of commits; and (iii) the most important bugs. For the opensource project 12.827 commits and 8.410 bugs have been analyzed while 4.663 commits and 1.898 bugs have been analyzed for the commercial project. Our results indicate that, for the open source project, the developers classified as core developers have contributed with more buggy commits (although they have contributed with the majority of commits), more code to the project (commit size) and more important bugs solved while the results could not indicate differences with statistical significance between developer groups for the commercial project

Hipertrofia ventricular e mortalidade cardiovascular em pacientes de hemodiálise de baixo nível educacional

FUNDAMENTO: A hipertrofia ventricular esquerda é potente preditor de mortalidade em renais crônicos. Estudo prévio de nosso grupo mostrou que renais crônicos com menor escolaridade têm hipertrofia ventricular mais intensa. OBJETIVO: Ampliar estudo prévio e verificar se a hipertrofia ventricular esquerda pode justificar a associação entre escolaridade e mortalidade cardiovascular de pacientes em hemodiálise. MÉTODOS: Foram avaliados 113 pacientes entre janeiro de 2005 e março de 2008 e seguidos até outubro de 2010. Foram traçadas curvas de sobrevida comparando a mortalidade cardiovascular, e por todas as causas dos pacientes com escolaridade de até três anos (mediana da escolaridade) e pacientes com escolaridade igual ou superior a quatro anos. Foram construídos modelos múltiplos de Cox ajustados para as variáveis de confusão. RESULTADOS: Observou-se associação entre nível de escolaridade e hipertrofia ventricular. A diferença estatística de mortalidade de origem cardiovascular e por todas as causas entre os diferentes níveis de escolaridade ocorreu aos cinco anos e meio de seguimento. No modelo de Cox, a hipertrofia ventricular e a proteína-C reativa associaram-se à mortalidade por todas as causas e de origem cardiovascular. A etiologia da insuficiência renal associou-se à mortalidade por todas as causas e a creatinina associou-se à mortalidade de origem cardiovascular. A associação entre escolaridade e mortalidade perdeu significância estatística no modelo ajustado. CONCLUSÃO: Os resultados do presente trabalho confirmam estudo prévio e demonstram, ademais, que a maior mortalidade cardiovascular observada nos pacientes com menor escolaridade pôde ser explicada por fatores de risco de ordem bioquímica e de morfologia cardíaca.

Effect of haematocrit on pump and kidney dysfunction after myocardial revascularization

Objective - Kidney dysfunction is a common complication after cardiac surgery. It occurs in 7 to 31% of the patients. The lowest haematocrit after cardiopulmonary bypass surgery (LHCT) has been identified as a risk factor for kidney dysfunction after cardiac surgery. The aim of this study is to determine whether different levels of haematocrit during cardiopulmonary bypass surgery are related to kidney dysfunction.Methods and results-A prospective study was conducted on consecutive adult patients undergoing myocardial revascularization. Preoperative renal function was assessed by baseline serum creatinine level (CrPre). Peak postoperative creatinine (CrPost) was defined as the highest daily in-hospital postoperative value. Peak fractional change in creatinine (% Delta Cr) was defined as the difference between the CrPre and CrePost represented as a percentage of the preoperative value. The LHTC was defined as the lowest recorded haematocrit prior to weaning from the initial pump run. A category variable was created for haematocrit based on the distribution of values. The category variable had the following cut-off points: less than 23%, 23.1 to 28% and greater than 28.1 %. Lowest haematocrit (26.62 +/- 4.15%), CPB (74.71 +/- 24.90 min), CrPre (1.23 +/- 0.37 mg/dl) and highest CrPost (1.52 +/- 0.47 mg/dl) data varied in near-normal fashion. Statistical significance has been observed in the < 23% lowest haematocrit group (CrIPOD and Cr5POD; P = 0.006) and the 23.1 28% lowest haematocrit level group (CrPre and Cr2POD; P = 0.047). CrPre and Cr5POD did not differ between groups (P > 0.05). The multiple linear regression model confirmed that the determinants for higher %Delta Cr were age, body surface area and preoperative serum creatinine level.Conclusion - The LHTC was not identified as a risk factor for kidney dysfunction after myocardial revascularization.

Avaliação de intervenção educativa sobre aleitamento materno dirigida a agentes comunitários de saúde

OBJETIVOS: avaliar ação educativa visando à capacitação de agentes comunitários de saúde em promoção e apoio ao aleitamento materno. MÉTODOS: estudo do processo e adequação de intervenção, com comparação de conhecimentos e práticas de 54 agentes, antes e dois meses após a ação. A intervenção, quatro oficinas teórico-práticas com oito horas cada, fundamentou-se em princípios da Educação Crítico-Reflexiva e em dois cursos de capacitação de equipes de maternidade. Os resultados foram expressos pelas diferenças dos escores médios de conhecimentos, práticas e total, adotando-se p<0,05 como nível crítico. RESULTADOS: houve aumento do escore médio de conhecimentos (21,0 para 26,6; p<0,001) e de escores de conhecimentos classificados como bons (37,0% para 88,8%, p<0,001). Não houve mudanças no escore de participação dos agentes em específicas ações de saúde, como grupos. O efeito da intervenção mais apontado pelos agentes foi sentir-se mais aceito e em melhores condições de participar da equipe multiprofissional em situações envolvendo cuidados com crianças. Mais da metade relatou melhora na qualidade e quantidade das orientações prestadas nas visitas domiciliarias. CONCLUSÕES: a intervenção tem efeitos positivos sobre conhecimentos e a prática dos agentes junto às famílias, mas não promove aumento da sua participação em específicas ações de saúde.

Effect of soluble fiber on hypertriglyceridemia and immune profile in HIV-positive individuals undergoing highly active antiretroviral therapy

The advent of highly active antiretroviral therapy (HAART), since 1996, represented a profound impact on the natural history of HIV-infection by promoting important and sustainable viral replication suppression and increasing survival and quality of life among seropositive patients. Nonetheless, antiretroviral therapy has been observed to be accompanied by metabolic alterations such as dyslipidemia, especially hypertriglyceridemia, insulin resistance, hyperglycemia and lipodystrophy (body fat redistribution). Epidemiological studies have demonstrated a correlation between high triglyceride (TG) levels and higher incidence of coronary artery disease (CAD). Some investigators suggest dietary intervention as part of hyperlipidemia treatment, including an increase in soluble fiber intake (10-25g/day). Whereas some studies have demonstrated that both cholesterol and serum triglyceride levels decrease with the use of food fiber, others have shown just a serum triglyceride decrease, and others failed to observe any alteration in lipid metabolism. The purpose of this study was to assess the effect of soluble fiber (R) (partially hydrolyzed guar gum) supplementation on hypertriglyceridemia and immune profile in HIVpositive individuals on HAART. Nineteen HIV-positive individuals with hypertriglyceridemia (serum levels >= 150 to < 500mg/dl) were studied. of these individuals, 63.16% were males and 36.84% females, with mean age of 43.52 +/- 9.22 years. These individuals had been on the same HAART regimen for at least six months, had no change in therapy during the study and received 20g/day of soluble fiber for four months at pre-established times. Clinical-nutritional, biochemical (total proteins, albumin, globulin, total cholesterol, LDL-c, HDL-c, TG, TG/HDL-c and LDLc/HDL-c), hematimetric (hemoglobin, hematocrit and total lymphocytes), and immunologic (lymphocytes T CD4(+), T CD8(+); T CD4(+)/CD8(+) ratio, viral load, TNF-alpha and IL-6) parameters were assessed in all patients at three time points (M0: pretreatment, M1: 30 days, and M2: four months after intervention). Significance level was set at 5% for all data statistically analyzed. Serum TG and TG/HDL-c ratio reduction was observed at all time points, but statistical significance was found just at M0 and M2. The remaining biochemical, hematimetric and immunologic parameters (lymphocytes T CD4(+), T CD8(+); T CD4(+)/ CD8(+) ratio, and viral load) showed no significant difference at all times. Regarding serum cytokines, TNF-alpha and IL-6 significantly decreased between M0 and M2, and only IL-6 reduced between M1 and M2. The data collected show that dietary and anthropometric parameters remained unchanged excluding potential confounding factors related with the effect of fiber supplementation on serum TG, TNF-alpha and IL-6. Thus, soluble fiber (R) contributed to an important reduction in hypertriglyceridemia and in the serum levels of the proinflammatory cytokines TNF-alpha and IL-6 in HIV-seropositive individuals on HAART. In addition, soluble fiber (R) might have minimized the process of atherosclerosis in these individuals, given that elevated serum levels of TG, TNF-alpha and IL-6 have been associated with the development of these lesions.

Levels of toxic and essential metals in maternal and umbilical cord blood from selected areas of South Africa-results of a pilot study

This pilot study uses concentrations of metals in maternal and cord blood at delivery, in seven selected geographical areas of South Africa, to determine prenatal environmental exposure to toxic metals. Samples of maternal and cord whole blood were analysed for levels of cadmium, mercury, lead, manganese, cobalt, copper, zinc, arsenic and selenium. Levels of some measured metals differed by site, indicating different environmental pollution levels in the regions selected for the study. Mercury levels were elevated in two coastal populations studied (Atlantic and Indian Ocean sites) with mothers from the Atlantic site having the highest median concentration of 1.78 mu g/L ranging from 0.44 to 8.82 mu g/L, which was found to be highly significant (p < 0.001) when compared to other sites, except the Indian Ocean site. The highest concentration of cadmium was measured in maternal blood from the Atlantic site with a median value of 0.25 mu g/L (range 0.05-0.89 mu g/L), and statistical significance of p < 0.032, when compared to all other sites studied, and p < 0.001 and p < 0.004 when compared to rural and industrial sites respectively, confounding factor for elevated cadmium levels was found to be cigarette smoking. Levels of lead were highest in the urban site, with a median value of 32.9 mu g/L (range 16-81.5 mu g/L), and statistically significant when compared with other sites (p < 0.003). Levels of selenium were highest in the Atlantic site reaching statistical significance (p < 0.001). All analysed metals were detected in umbilical cord blood samples and differed between sites, with mercury being highest in the Atlantic site (p < 0.001), lead being highest in the urban site (p < 0.004) and selenium in the Atlantic site (p < 0.001). To the best of our knowledge this pilot investigation is the first study performed in South Africa that measured multiple metals in delivering mothers and umbilical cord blood samples. These results will inform the selection of the geographical sites requiring further investigation in the main study.

Fatores de risco para macrossomia fetal em gestações complicadas por diabete ou por hiperglicemia diária

OBJETIVO: identificar fatores de risco para a macrossomia fetal na população de gestantes portadoras de diabete ou hiperglicemia diária. MÉTODOS: estudo retrospectivo, tipo caso-controle, incluindo 803 pares de mães e recém-nascidos desta população específica, distribuídos em dois grupos: macrossômicos (casos, n=242) e não macrossômicos (controles, n=561). Foram comparadas variáveis relativas à idade, paridade, peso e índice de massa corporal (IMC), ganho de peso (GP), antecedentes de diabete, hipertensão arterial e tabagismo, tipo e classificação do diabete e indicadores do controle glicêmico no terceiro trimestre. As médias foram avaliadas pelo teste F e as variáveis categorizadas foram submetidas à análise univariada, utilizando-se o teste do chi². Os resultados significativos foram incluídos no modelo de regressão múltipla, para identificação do risco independente de macrossomia, considerando-se OR, IC 95% e valor de p. Para todas as análises foi estabelecido o limite de significância estatística de 5% (p<0,05). RESULTADOS: observou-se associação significativa entre macrossomia e GP maior que 16 kg, IMC >25 kg/m², antecedentes pessoais, obstétricos e, especificamente, o de macrossomia, classificação nos grupos de Rudge (IB e IIA + IIB), média glicêmica (MG) >120 mg/dL e média de glicemia pós-prandial >130 mg/dL no terceiro trimestre. Na análise de regressão múltipla, o GP >16 kg (OR=1,79; IC 95%: 1,23-1,60), o IMC >25 kg/m² (OR=1,83; IC 95%: 1,27-2,64), o antecedente pessoal de diabete (OR=1,56; IC 95%: 1,05-2,31) e de macrossomia (OR=2,37; IC 95%: 1,60-3,50) e a MG >120 mg/dL no terceiro trimestre (OR=1,78; IC 95%: 1,13-2,80) confirmaram risco independente para macrossomia nestas gestações de risco. CONCLUSÃO: o GP superior a 16 kg, o IMC maior ou igual a 25 kg/m², a MG superior a 120 mg/dL no terceiro trimestre e a presença de antecedentes pessoais de diabete ou de macrossomia foram identificados como fatores de risco para macrossomia fetal em gestantes portadoras de diabete ou de hiperglicemia diária.
