[Adverse events following diphtheria, pertussis and tetanus vaccinations and factors associated with severity]. / Eventos adversos pós-vacina contra a difteria, coqueluche e tétano e fatores associados à sua gravidade.

OBJECTIVE: To analyze adverse events following vaccinations against diphtheria, pertussis and tetanus (AEFV-DPT) and to investigate factors associated with event severity. METHODS: A cross-sectional study was carried out with a descriptive and analytical component covering AEFV-DPT that were notified in the State of São Paulo, Brazil, between 1984 and 2001, among children less than seven years old. Cases were defined as used in AEFV-DPT surveillance; the data source was AEFV-DPT passive surveillance. In calculating the rates, the numerator was the number of AEFV-DPT and as denominator was the number of doses applied. The association between severity of AEFV-DPT and the exposures of interest was investigated by means of non-adjusted and adjusted estimates of odds ratios, with their respective 95% confidence intervals, using non-conditional logistic regression. RESULTS: A total of 10,059 AEFV-DPT were identified, corresponding to 6,266 children who presented one or more AEFV-DPT, 29.5% were hospitalized and 68.2% presented contraindications for subsequent DPT doses. Around 75% of the events occurred during the first six hours after vaccination. The most frequent AEFV-DPT were: fever < 39.5 degrees C, local reactions, hypotonic-hyporesponsive episodes and convulsion. Time interval of less than one hour between vaccination and the event (OR = 2.1), first dose applied (OR=5.8) and previous personal (OR=2.2) and family (OR=5.3) neurological histories were independently associated with severe events. CONCLUSIONS: Passive surveillance of AEFV-DPT was shown to be useful for monitoring the safety of the DPT vaccine, through describing the characteristics and magnitude of these events, and also enabling identification of possible factors associated with severe forms.

OBJETIVO: Avaliar os eventos adversos pós-vacina contra a difteria, coqueluche e tétano (EAPV-DPT) e os fatores associados à sua gravidade. MÉTODOS: Estudo transversal com componente descritivo e analítico, abrangendo os eventos adversos pós-vacina DPT notificados no Estado de São Paulo, de 1984 a 2001, entre crianças menores de sete anos de idade. A definição de caso foi a adotada pela vigilância de EAPV-DPT; os dados obtidos foram originados da vigilância passiva desses eventos. No cálculo das taxas, o numerador foram os EAPV e o denominador o número de doses aplicadas. A associação entre a gravidade dos EAPV-DPT e as exposições de interesse foi investigada pelas estimativas não ajustadas e ajustadas da odds ratio, com os respectivos intervalos de 95 por cento de confiança, usando regressão logística não condicional. RESULTADOS: Identificaram-se 10.059 EAPV-DPT relativos a 6.266 crianças, apresentando um ou mais EAPV, 29,5 por cento foram internadas e em 68,2 por cento houve contra-indicação das doses subseqüentes de DPT. Cerca de 75 por cento dos eventos ocorreram nas primeiras seis horas após a aplicação da vacina. Os eventos mais freqüentes foram: febre<39,5°C, reação local, evento hipotônico hiporresponsivo e convulsão. Mostraram-se independentemente associadas à gravidade: intervalo inferior a uma hora entre a aplicação da vacina e o evento (OR=2,1), primeira dose aplicada (OR=5,8), antecedentes neurológicos pessoais (OR=2,2) e familiares (OR=5,3). CONCLUSÕES: A vigilância passiva de EAPV mostrou-se útil no monitoramento da segurança da vacina DPT, descrevendo as características e a magnitude desses eventos, assim como permitiu identificar possíveis fatores associados às formas graves.

[Prevalence of a set of risk factors for chronic diseases in the city of São Paulo, Brazil]. / Prevalência de alguns fatores de risco para doenças crônicas na cidade de São Paulo.

OBJECTIVE: To estimate the prevalence of a set of risk factors for non-transmissible chronic diseases and compare it to that found 15-16 years ago in a similar survey. METHODS: A cross-sectional household survey was carried out comprising a random sample of people aged 15-59 years in the city of São Paulo between 2001 and 2002. The total of 2,103 people answered a questionnaire and had their blood pressure, weight, height, waist and hip circumferences measured. For a third of these participants, their total cholesterol, HDL-cholesterol, triglycerides and glucose levels were determined. RESULTS: The total age-adjusted prevalences in the study age group were as follows: smoking, 22.6%; uncontrolled blood pressure, 24.3%; obesity, 13.7%; increased waist circumference, 19.7%; total cholesterol >or =240 mg/dL, 8.1%; HDL-cholesterol <40 mg/dL, 27.1%; triglycerides > or =200 mg/dL, 14.4%; and blood glucose > or =110 mg/dL, 6.8%. Smoking, uncontrolled blood pressure, high total cholesterol, low HDL-cholesterol and high triglycerides were significantly more prevalent in men than women. CONCLUSIONS: The prevalences of a set of risk factors for chronic diseases showed men to have a poorer condition than women. In comparison to the previous survey, the prevalence of uncontrolled blood pressure remained unchanged but the prevalence of smoking has significantly lowered.

Prevalência de alguns fatores de risco para doenças crônicas na cidade de São Paulo / Prevalence of a set of risk factors for chronic diseases in the city of São Paulo, Brazil

OBJETIVO: Estimar as prevalências de fatores de risco para doenças crônicas não-transmissíveis e compará-las com as obtidas há 15-16 anos em inquérito semelhante. MÉTODOS: Estudo transversal de base populacional com amostra aleatória de pessoas com 15 a 59 anos de idade, realizado no Município de São Paulo entre 2001 e 2002. Foram entrevistadas 2.103 pessoas que responderam a um questionário, quando também foram feitas medidas de pressão arterial, peso, estatura e circunferências do abdome e do quadril. Em um terço dos entrevistados foram dosados colesterol total, HDL-colesterol, triglicérides e glicose de jejum. RESULTADOS: As prevalências totais ajustadas por idade, na faixa etária de 15 a 59 anos, foram as seguintes: tabagismo, 22,6 por cento; pressão arterial não controlada, 24,3 por cento; obesidade, 13,7 por cento; circunferência abdominal aumentada, 19,7 por cento; colesterol total >240 mg/dl, 8,1 por cento; HDL-colesterol <40 mg/dl, 27,1 por cento; triglicérides >200 mg/dl, 14,4 por cento; e glicemia >110 mg/dl, 6,8 por cento. Tabagismo, pressão arterial não controlada, colesterol total elevado, HDL-colesterol diminuído e triglicérides elevados foram significantemente mais prevalentes em homens do que em mulheres. CONCLUSÕES: Os resultados quanto à prevalência de alguns fatores de risco para doenças crônicas mostraram que os homens estão em pior situação do que as mulheres. Comparados aos resultados de inquérito anterior, a percentagem de pressão arterial não controlada permaneceu inalterada, mas a de tabagismo diminuiu significantemente.
