Background: This study describes medication use by women up to 3 months postpartum and evaluates the association between medication use by women who were still breastfeeding at 3 months postpartum and weaning at 6 and 12 months. Methods: Population-based cohort, including women who breastfed ( n = 3988). Medications were classified according to Hale's lactation risk categories and Brazilian Ministry of Health criteria. Duration of breastfeeding was analysed using Cox regression models and Kaplan-Meier curves, including only women who were still breastfeeding at three months postpartum. Results: Medication use with some risk for lactation was frequent (79.6% regarding Hale's risk categories and 12.3% regarding Brazilian Ministry of Health criteria). We did not find statistically significant differences for weaning at 6 or 12 months between the group who did not use medication or used only compatible medications and the group who used medications with some risk for lactation, according to both criteria. Conclusions: Our study found no association between weaning rates across the different breastfeeding safety categories of medications in women who were still breastfeeding at three months postpartum. Therefore, women who took medications and stopped breastfeeding in the first three months postpartum because of adverse side-effects associated with medications could not be addressed in this analysis.

Objective To estimate the prevalence of use of drugs to treat gastrointestinal disorders, according to demographic, socioeconomic, and health characteristics of the Brazilian population. Methods This is a population-based survey that interviewed individuals residing in cities of the five regions in Brazil. The study sample was composed of 32,348 individuals aged 20 or more years. The profile of use of drugs for gastrointestinal disorders was evaluated considering the variables sex, age, healthcare plan, region, and number of chronic diseases. We also analyzed the frequency of individuals who declared using other drugs, besides those already employed for treatment of gastrointestinal disorders. Additionally, the estimated frequencies of the drug classes used were determined. Results The prevalence of use of drugs for gastrointestinal disorders in Brazil was 6.9% (95% confidence interval - 6.4-7.6), higher in females, among persons aged over 60 years, in those who had a private healthcare insurance, and presented with two or more chronic diseases. It was noted that 42.9% of the aged who used drugs for gastrointestinal disorders were also on polypharmacy. As to the classes of drugs, 82% corresponded to drugs for the food tract and metabolism, particularly proton pumps inhibitors. Conclusion The use of drugs for treatment of gastrointestinal disorders was significant among women and elderly. In this age group, consumption may be linked to gastric protection due to polypharmacy. This study is an unprecedented opportunity to observe the self-reported consumption profile of these drugs in Brazil and, therefore, could subsidize strategies to promote their rational use.

Objective: Trace the pattern of drug use during delivery hospitalization., Method: Cross-sectional study carried out from June to October 2015, included in the 2015 Pelotas births cohort. All women living in the urban area of the city who were hospitalized for delivery were part of the sample. We collected information regarding drug prescription and drug use by mothers during the whole period of hospitalization. Sociodemographic data were obtained in interview after delivery, and other data were obtained from medical charts. The drugs were classified according to the Anatomical Therapeutic Chemical system., Results: All study participants (1,392 women) used at least one drug, with the mean amount being larger the higher the age of the mother, both prepartum/during delivery and postpartum. It was also higher in cases of spinal anesthesia or general anesthesia, cesarean deliveries, school hospitals, and longer hospitalizations. Analysis of the sample as a whole showed no significant difference in the number of drugs used according to hospitalization type, but when stratified by length of hospital stay the mean was higher in SUS hospitalizations than in private and health insurance hospitalizations. Drugs for the nervous system were the most used (30.5%), followed by drugs for the alimentary tract and metabolism (13.8%). The use of anti-infective agents and drugs that act on the cardiovascular and respiratory systems was higher in mothers who underwent cesarean delivery. This study showed high drug consumption in the delivery hospitalization period, and showed cesarean delivery and epidural anesthesia as the main factors related to high drug consumption in this period., Conclusions: We found high drug consumption in the delivery hospitalization period, and the main factors were cesarean delivery and epidural anesthesia. Drugs that act on the nervous system were the most used.

Objective:: To assess the agreement between three recall periods for self-reported drug use using a 24-hour recall period as reference., Methods:: Participants were allocated into three groups with different recall periods of 7, 14 and 30 days and were interviewed at two different times. A 24-hour recall questionnaire was answered during the first interview, and a questionnaire on drug use over the different recall periods tested was answered during the second interview. The agreement between the questionnaires was evaluated using percent agreement and kappa., Results:: For continuous drugs, percent agreement varied between 92 and 99% and kappa varied between 0.71 and 0.97 for three periods tested. For drugs of occasional use, percent agreement varied between 63 and 81% and kappa varied between 0.27 and 0.52. The prevalence of drugs, particularly those of occasional use, increases with time., Conclusions:: The high level of agreement between the three recall periods suggests that all of them are valid for the investigation of drugs of continuous use.

Objective: To analyze the prevalence of medicine use by the Brazilian population and its distribution according to sociodemographic factors., Methods: Study using data from the Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines), a nationwide household survey of a representative sample of the Brazilian urban population. The data were collected between September 2013 and February 2014. The overall use of medicines, defined as the use of any medicine, use of medicines for treating chronic medical conditions and for acute health conditions, was evaluated. The independent variables included gender, age group, socioeconomic position, and region of Brazil. Analyzes included prevalence calculations, 95% confidence intervals (95%CI) and Pearson Chi-square tests to evaluate the differences between groups, considering a 5% level of significance., Results: The prevalence of medicines use was 50.7% (95%CI 49.3-52.2), with 39.3% (95%CI 37.5-41.1) accounting for men and 61.0% (95%CI 59.3-62.6) for women. Medicines use was observed to increase with increasing age, except among children within the zero to four years age group. The lowest prevalence for medicines use was found among those with a low socioeconomic position and those who reside in the North region of Brazil. The prevalence of medicine use to treat chronic diseases was 24.3% (95%CI 23.3-25.4), whereas it was 33.7% (95%CI 32.1-35.4) for treating acute diseases., Conclusions: We found extensive variability in the prevalence of medicines use across regions of Brazil. The poorest regions (North, Northeast, and Midwest) have a lower prevalence of medicines use to treat chronic diseases, indicating the need to minimize inequalities in access to medicines within the country., Objetivo: Analisar a prevalência do uso de medicamentos pela população brasileira e sua distribuição segundo aspectos sociodemográficos., Métodos: Estudo com dados da Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM), pesquisa nacional de base populacional, realizada entre setembro de 2013 e fevereiro de 2014 em residências de municípios urbanos. Avaliou-se o uso de todos os medicamentos (global), uso de medicamentos para doenças crônicas e uso de medicamentos para doenças agudas. As variáveis independentes utilizadas foram sexo, idade, classificação econômica e região do País. Foram calculados prevalências e intervalos de confiança de 95% (IC95%) e aplicado teste Qui-quadrado de Pearson para avaliação das diferenças entre os grupos, considerando o nível de significância de 5%., Resultados: A prevalência global de uso de medicamentos foi de 50,7% (IC95% 49,3-52,2), sendo 39,3% (IC95% 37,5-41,1) no sexo masculino e 61,0% (IC95% 59,3-62,6) no sexo feminino. Observou-se aumento nas prevalências de uso com a idade (exceto de zero a quatro anos). As menores prevalências de uso ocorreram no grupo mais pobre e na região Norte do País. A prevalência de uso de medicamentos para doenças crônicas foi de 24,3% (IC95% 23,3-25,4) e para doenças agudas foi de 33,7% (IC95% 32,1-35,4)., Conclusões: Existe grande variabilidade nas prevalências globais de uso de medicamentos por regiões brasileiras. As regiões consideradas mais pobres (Norte, Nordeste e Centro-Oeste) apresentam menores prevalências de uso de medicamentos para doenças crônicas, o que indica a necessidade de minimizar as desigualdades no acesso aos medicamentos dentro do País., Competing Interests: The authors declare no conflict of interest.

The scope of this article was to estimate the prevalence of medication use in children between zero and six years old, analyzing the associated socio-demographic characteristics, and evaluating the adequacy of the medication with respect to pediatric recommendations and restrictions per age group. A cross-sectional study was conducted by means of cluster sampling on a sample comprised of children aged six or under, residents of a city in the south of Brazil. A standardized questionnaire about medication use 15 days prior to the interview was applied. A descriptive analysis was carried out, and the association between medication use and socio-demographic factors was evaluated, as well as the analysis of the pediatric adequacy of the most prevalent medication. Of the 687 children evaluated, 52% used at least one drug in the period. Associations between medication use and socio-demographic characteristics were not found, with the exception of per capita monthly income. The most prevalent medication was paracetamol (17.1%), followed by amoxicillin (9.5%) and dipyrone (8.4%). Among the ten drugs most used in children, six had pediatric restrictions for the age group. The results indicate significant use of medication, including medication with age restrictions, particularly for children under two years of age.
