Impact of the Covid-19 pandemic on small vulnerable newborns
Background: We examined COVID-19's impact on the number of small vulnerable newborns (SVN) at national and regional levels in Peru and Brazil. Methods: Using national birth registries, we examined monthly numbers of preterm (PT), low birthweight (LBW), and small for gestational age (SGA) newborns. We analysed COVID-19's impact on SVN using two interrupted time series models. We estimated SVN's expected numbers in the absence of the pandemic using…
Changes of adolescent sleep patterns during the Covid-19 pandemic
OBJECTIVE: The COVID-19 pandemic has raised numerous concerns regarding its effects on individuals' health and lifestyle. We aim to analyze potential changes in adolescent sleep patterns from before and during the pandemic and identify specific predictors of changes. METHODS: A subgroup of adolescents from a population-based birth cohort from Pelotas, Brazil, was assessed pre-pandemic (T1, November-2019 to March-2020) and peri-pandemic (T2, Augus…
The impact of the Covid-19 pandemic on trends in stillbirths, under-5 and maternal mortality in Brazil
Background: Despite the proliferation of studies on the impact of the coronavirus disease 2019 (COVID-19) pandemic, there is less evidence on the indirect death toll compared to the health system and service provision disruptions. We assessed the impact of the COVID-19 pandemic on national and regional trends and differences in stillbirths, under-5 and maternal deaths in Brazil. Methods: We used the nationwide routine health information system da…
Measles vaccination in Brazil
The re-emergence of vaccine-preventable diseases due to the decline in vaccine coverage (VC) has been documented in several countries. The objective was to analyze the VC, the homogeneity of VC, and measles cases in Brazil from 2011 to 2021, focusing on the period of the COVID-19 pandemic, its temporal trend, space-time distribution, and factors associated with clusters of lower VC. This is an ecological study on measles VC (dose 1), with methods…
Vacinação contra poliomielite no Brasil de 2011 a 2021
A queda de coberturas vacinais (CV) na infância, entre elas a da poliomielite, vem se tornando uma preocupação sanitária. O objetivo foi analisar a tendência temporal das coberturas das três doses da vacina contra a poliomielite nos primeiros 12 meses de vida entre 2011 e 2021, com destaque na pandemia de COVID-19, além de mapear as CV no Brasil. Foi realizado um estudo ecológico com técnicas de série temporal interrompida (STI) e análise espacia…
Vacinação do sarampo no Brasil
A reemergência de doenças imunopreveníveis devido à queda das coberturas vacinais (CV) tem sido documentada em vários países. O objetivo foi analisar a CV, a homogeneidade das CV e os casos de sarampo no Brasil de 2011 a 2021, com enfoque no período da pandemia de COVID-19, sua tendência temporal, distribuição espaço-temporal e fatores associados aos aglomerados de menor CV. Trata-se de um estudo ecológico sobre a CV de sarampo (dose 1), com méto…
Vaccination against poliomyelitis in Brazil from 2011 to 2021
The drop in childhood vaccination coverage (VC), including poliomyelitis, has become a health concern. The objective was to analyze the temporal trend of coverage of the three doses of the polio vaccine in the first 12 months of life between 2011 and 2021, in addition to mapping vaccination coverage in Brazil, including the COVID-19 pandemic period. An ecological study was carried out using interrupted time series (STI) techniques and spatial ana…

Burden of physical inactivity and hospitalization costs due to chronic diseases
OBJECTIVE To evaluate the physical inactivity-related inpatient costs of chronic non-communicable diseases. METHODS This study used data from 2013, from Brazilian Unified Health System, regarding inpatient numbers and costs due to malignant colon and breast neoplasms, cerebrovascular diseases, ischemic heart diseases, hypertension, diabetes, and osteoporosis. In order to calculate the share physical inactivity represents in that, the physical ina…
