Objetivo: Determinar a prevalência da automedicação em crianças e adolescentes dos municípios de Limeira e Piracicaba (SP), correlacionando-a a indicadores sociodemográficos e utilização de serviços de saúde (pública ou privada).Métodos: Estudo descritivo tipo inquérito populacional domiciliar de uma amostra aleatória simples de ambos os municípios, constituída de 772 moradores procedentes de 85 setores censitários selecionados por meio de amostragem por conglomerado. Critérios de inclusão: idade ≤ 18 anos; entrevista obrigatória com um dos responsáveis legais; ter consumido pelo menos um medicamento nos 15 dias prévios à data da entrevista. Segundo a orientação de uso de medicamentos, os participantes foram divididos em dois grupos de estudo: automedicação (orientação leiga) e prescrição médica. Foram realizados testes de associação linear, análise descritiva das variáveis e regressão logística múltipla. Resultados:A prevalência da automedicação foi de 56,6%. Os principais responsáveis e indutores da automedicação foram as mães (51%) e funcionários de farmácia (20,1%). Os principais grupos de medicamentos administrados na automedicação foram: analgésicos/antipiréticos e antiinflamatórios não-hormonais (52,9%); medicações de ação nos tratos respiratório (15,4%) e gastrointestinal (9,6%); e antibióticos sistêmicos (8,6%). As situações que mais motivaram a automedicação foram afecções respiratórias (17,2%), febre (15%) e cefaléia (14%). Indivíduos na faixa etária de 7-18 anos (razão de chances = 2,81) e usuários de serviços públicos de saúde (razão de chances = 1,52) apresentaram risco aumentado de automedicação. Conclusões:A prevalência da automedicação em crianças e adolescentes foi alta, reforçando a necessidade de intervenção das autoridades de saúde na prevenção desses agravos. Results:The prevalence of self-medication was 56.6%. Mothers (51%) and drugstore employees (20.1%) were most frequently responsible for self-medication. The main groups of self-prescribed drugs were: analgesic/antipyretic and non-hormonal antiinflammatory drugs (52.9%); drugs acting on the respiratory tract (15.4%) and gastrointestinal drugs (9.6%); and systemic antibiotics (8.6%). The situation that most commonly motivated selfmedication were respiratory diseases (17.2%), fever (15%), and headache (14%). Subjects in the age group of 7-18 years (odds ratio = 2.81) and public health care users (odds ratio = 1.52) showed increased risk for self-medication. Conclusions:The prevalence of self-medication in children and adolescents was high, which reinforces the need for public health interventions aiming at preventing this practice.J Pediatr (Rio J). 2007;83(5):453-458: Children, adolescents, drugs, self-medication, pharmacoepidemiology.
In this study, there was a predominance of patients with UC, young people under 40 years of age, individuals with racial miscegenation, and low annual incomes.
BackgroundMany factors have been associated with circulation of the dengue fever virus and vector, although the dynamics of transmission are not yet fully understood. The aim of this work is to estimate the spatial distribution of the risk of dengue fever in an area of continuous dengue occurrence.MethodsThis is a spatial population-based case-control study that analyzed 538 cases and 727 controls in one district of the municipality of Campinas, São Paulo, Brazil, from 2006-2007, considering socio-demographic, ecological, case severity, and household infestation variables. Information was collected by in-home interviews and inspection of living conditions in and around the homes studied. Cases were classified as mild or severe according to clinical data, and they were compared with controls through a multinomial logistic model. A generalized additive model was used in order to include space in a non-parametric fashion with cubic smoothing splines.ResultsVariables associated with increased incidence of all dengue cases in the multiple binomial regression model were: higher larval density (odds ratio (OR) = 2.3 (95%CI: 2.0-2.7)), reports of mosquito bites during the day (OR = 1.8 (95%CI: 1.4-2.4)), the practice of water storage at home (OR = 2.5 (95%CI: 1.4, 4.3)), low frequency of garbage collection (OR = 2.6 (95%CI: 1.6-4.5)) and lack of basic sanitation (OR = 2.9 (95%CI: 1.8-4.9)). Staying at home during the day was protective against the disease (OR = 0.5 (95%CI: 0.3-0.6)). When cases were analyzed by categories (mild and severe) in the multinomial model, age and number of breeding sites more than 10 were significant only for the occurrence of severe cases (OR = 0.97, (95%CI: 0.96-0.99) and OR = 2.1 (95%CI: 1.2-3.5), respectively. Spatial distribution of risks of mild and severe dengue fever differed from each other in the 2006/2007 epidemic, in the study area.ConclusionsAge and presence of more than 10 breeding sites were significant only for severe cases. Other predictors of mild and severe cases were similar in the multiple models. The analyses of multinomial models and spatial distribution maps of dengue fever probabilities suggest an area-specific epidemic with varying clinical and demographic characteristics.
