ABSTRACT
The Happy Child Program (Programa Criança Feliz - PCF, in Portuguese) reaches 1.4 million Brazilian children under three years of age with home visits aimed at promoting neuropsychomotor development. Based on a conceptual model, PCF implementation and impact were evaluated in a randomized study in 30 municipalities. A total of 3,242 children were allocated to the intervention (IG) or control (CG) group, 80.0% of whom were prospectively followed up from late 2018 to late 2021. Development was assessed by the Ages and Stages Questionnaire (ASQ3). During the three-year study period, visits were replaced by virtual contacts for an average of 12 months due to COVID-19. At the endline survey, intent-to-treat analyses showed mean scores of 203.3 in the IG and 201.3 in the CG. Additional analyses using instrumental variables and propensity scores matching also showed no effect, since the number of contacts with the program was not associated with ASQ3 scores. No impact was observed on stimulation, responsive interactions or psychological attributes of children. The implementation study revealed low coverage in the IG, contamination of the CG, deficiencies in management and low quality of visits in many municipalities. The study did not demonstrate an impact of PCF implemented under routine conditions, but provides elements for its improvement.
O Programa Criança Feliz (PCF) atinge 1,4 milhão de crianças brasileiras menores de três anos com visitas domiciliares visando o desenvolvimento neuropsicomotor. Com base em modelo conceitual, avaliou-se implementação e impacto do PCF em estudo randomizado, em 30 municípios. Ao todo 3.242 crianças foram alocadas para o grupo intervenção (GI) ou controle (GC), sendo 80,0% acompanhadas prospectivamente durante três anos. O desenvolvimento foi avaliado pelo Ages and Stages Questionnaire (ASQ3). Análises por intenção de tratar mostraram escores médios de 203,3 no GI e 201,3 no GC. Análises adicionais com variáveis instrumentais e emparelhamento por escores de propensão tampouco mostraram efeito, uma vez que o número de contatos recebidos não esteve associado aos escores ASQ3. Tampouco foi observado impacto sobre estimulação, interações responsivas ou atributos psicológicos das crianças. As visitas foram interrompidas durante 12 meses devido à COVID-19, sendo substituídas por contatos virtuais. O estudo de implementação revelou baixa cobertura no GI, contaminação do GC, deficiências na gestão e baixa qualidade das visitas em muitos municípios. O estudo não demonstrou impacto do PCF implementado sob condições de rotina e fornece elementos para seu aprimoramento.

PURPOSE: Our aim was to assess the impact of COVID-19 on depressive symptoms among mothers from a population-based birth cohort in Pelotas, Southern Brazil. METHODS: A subgroup of mothers from the Pelotas 2004 Birth Cohort was assessed pre-pandemic (November,2019 to March,2020) and mid-pandemic (August-December,2021). In both follow-ups, depressive symptoms were assessed using the Edinburgh Postnatal Depression Scale (EPDS). Pre-pandemic (T1) and pandemic-related predictors (T2) were analyzed. Prevalence of depression (EPDS score ≥ 13) at T1 and T2 were compared with chi-square test. Changes in EPDS from T1 to T2 were estimated by multivariate latent change score modelling. RESULTS: 1,550 women were assessed. Prevalence of depression increased 38.1% (from 18.9% at T1 to 26.1% at T2) (p < 0.001). At T1, higher schooling, higher family income and being employed or working were related to lower EPDS, whereas being beneficiary of a cash transfer program and a larger number of people living in the household predicted higher EPDS. The deterioration of ones' own perception of quality of overall health (ß = 0.191; SE = 0.028; p < 0.001) and worst family financial situation due to the pandemic (ß = 0.083; SE = 0.024; p = 0.001) predicted the increase in EPDS from T1 to T2. CONCLUSION: Almost two years after the beginning of the pandemic, the prevalence of depressive symptoms among the women was higher than before the pandemic. The deterioration of ones' own perception of quality of overall health and worst family financial situation due to the pandemic are proxies for the effect of COVID-19 pandemic (the true exposure of interest) in the women mental health.

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 of interrupted time series and evaluation of spatio-temporal disposition, through the sweep test to identify clusters of VC. Starting in 2015, we observe a progressive decline in VC and homogeneity, with an accentuation after 2020, in all regions, particularly in the North and Northeast. Low VC clusters were associated with worse human development indicators, social inequality, and less access to the Family Health Strategy. In Brazil, the pandemic intensified health inequalities with low VC of measles in socially more vulnerable and unequal municipalities. There is a risk of virus circulation, however, the challenge of strengthening primary care, improving health communication and guaranteeing access to the vaccine, reducing missed opportunities for vaccination and vaccine hesitancy, is highlighted.
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 métodos de série temporal interrompida e de avaliação da disposição espaço-temporal, por meio do teste de varredura na identificação de aglomerados de CV. A partir de 2015, observa-se queda progressiva das CV e da homogeneidade, acentuando-se após 2020 em todas as regiões, particularmente Norte e Nordeste. Aglomerados de baixa CV foram associados a piores indicadores de desenvolvimento humano, desigualdade social e menor acesso à Estratégia de Saúde da Família. No Brasil, a pandemia intensificou as iniquidades em saúde, com baixas CV de sarampo em municípios socialmente mais vulneráveis e desiguais. Há risco de circulação do vírus, reafirmando o desafio de fortalecer a atenção básica, aprimorar a comunicação em saúde e garantir acesso à vacina, diminuindo oportunidades perdidas de vacinação e a hesitação vacinal.

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 analysis, with data from the National Immunization Program Information System. The VC trend was adjusted by the Newey-West variance estimator according to the federated units and the Brazilian Deprivation Index. The VC distribution was estimated by Bayesian models and the spatial clusters by the global and local Moran index, identifying areas of lower coverage in the health regions. There was a reduction in the VC over the period in all regions, being more pronounced in the North and Northeast regions and during the Covid-19 pandemic. The biggest drops were identified in states and health regions with greater social vulnerability after 2019. The drop in VC shows that the risk of reintroduction of the wild virus is imminent and the challenges need to be faced with the strengthening of the Brazilian Health System (SUS).
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 espacial, a partir dos dados do Sistema de Informação do Programa Nacional de Imunização. A tendência da CV foi ajustada pelo estimador de variância de Newey-West, segundo as unidades federadas e o Índice de Privação Brasileiro. A distribuição da CV foi estimada por modelos bayesianos e os aglomerados espaciais pelos índices de Moran global e local, identificando áreas de menor cobertura nas Regiões de Saúde. Observa-se perda da CV ao longo do período em todas as regiões do país, sendo maiores no Norte e no Nordeste e se acentuando durante a pandemia. As maiores quedas foram identificadas em estados e regiões de saúde com maior vulnerabilidade social. A queda na CV mostra que o risco de reintrodução do vírus selvagem é iminente e os desafios precisam ser enfrentados com o fortalecimento do Sistema Único de Saúde.

BACKGROUND: The epidemiology of childhood SARS-CoV-2 infection and COVID-19-related illness remains little studied in high-transmission tropical settings, partly due to the less severe clinical manifestations typically developed by children and the limited availability of diagnostic tests. To address this knowledge gap, we investigate the prevalence and predictors of SARS-CoV-2 infection (either symptomatic or not) and disease in 5 years-old Amazonian children. METHODOLOGY/PRINCIPAL FINDINGS: We retrospectively estimated SARS-CoV-2 attack rates and the proportion of infections leading to COVID-19-related illness among 660 participants in a population-based birth cohort study in the Juruá Valley, Amazonian Brazil. Children were physically examined, tested for SARS-CoV-2 IgG and IgM antibodies, and had a comprehensive health questionnaire administered during a follow-up visit at the age of 5 years carried out in January or June-July 2021. We found serological evidence of past SARS-CoV-2 infection in 297 (45.0%; 95% confidence interval [CI], 41.2-48.9%) of 660 cohort participants, but only 15 (5.1%; 95% CI, 2.9-8.2%) seropositive children had a prior medical diagnosis of COVID-19 reported by their mothers or guardians. The period prevalence of clinically apparent COVID-19, defined as the presence of specific antibodies plus one or more clinical symptoms suggestive of COVID-19 (cough, shortness of breath, and loss of taste or smell) reported by their mothers or guardians since the pandemic onset, was estimated at 7.3% (95% CI, 5.4-9.5%). Importantly, children from the poorest households and those with less educated mothers were significantly more likely to be seropositive, after controlling for potential confounders by mixed-effects multiple Poisson regression analysis. Likewise, the period prevalence of COVID-19 was 1.8-fold (95%, CI 1.2-2.6-fold) higher among cohort participants exposed to food insecurity and 3.0-fold (95% CI, 2.8-3.5-fold) higher among those born to non-White mothers. Finally, children exposed to household and family contacts who had COVID-19 were at an increased risk of being SARS-CoV-2 seropositive and-even more markedly-of having had clinically apparent COVID-19 by the age of 5 years. CONCLUSIONS/SIGNIFICANCE: Childhood SARS-CoV-2 infection and COVID-19-associated illness are substantially underdiagnosed and underreported in the Amazon. Children in the most socioeconomically vulnerable households are disproportionately affected by SARS-CoV-2 infection and disease.

According to the World Health Organization, Brazil ranks third in COVID-19 cases and second in deaths globally. The most severely impacted by this shock are the approximately 10 million Brazilians that live in extreme poverty. This vulnerability is evident in youth, financially, and in their well-being and mental health. Like other cash transfer programmes globally, the Programa Bolsa Familia (PBF) is currently being adapted to support individuals and families during the pandemic. The current environment offers a unique opportunity for PBF to focus on young people and tackle poverty from a broader perspective. The PBF can expand its scope to address the longer-term mental health impacts of economic crises and poverty, besides addressing urgent food security and survival needs. This approach could enhance youth's future life chances and break the vicious cycle between mental illness and poverty that spirals many young people into socioeconomic and mental health disadvantages.

Junto a outros programas de transferencia de renda, o Programa Bolsa Familia (PBF) foi adaptado para melhor contribuir durante a pandemia. Esse contexto oferece uma oportunidade unica para que o PBF foque em jovens e aborde a pobreza de forma mais ampla. Alem de cobrir as necessidades basicas, o PBF poderia ampliar seu alcance visando a impactos economicos e de saude mental de longo prazo. Esse enfoque poderia melhorar as oportunidades de vida de jovens e romper o ciclo vicioso entre problemas de saude mental e pobreza que os mantem em situacao de vulnerabilidade social.

ABSTRACT
Social protection measures can play an important part in securing livelihoods and in mitigating short-term and long-term economic, social, and mental health impacts of the COVID-19 pandemic. In particular, cash transfer programmes are currently being adapted or expanded in various low-income and middle-income countries to support individuals and families during the pandemic. We argue that the current crisis offers an opportunity for these programmes to focus on susceptible young people (aged 15-24 years), including those with mental health conditions. Young people living in poverty and with mental health problems are at particular risk of experiencing adverse health, wellbeing, and employment outcomes with long-term consequences. They are also at risk of developing mental health conditions during this pandemic. To support this population, cash transfer programmes should not only address urgent needs around food security and survival but expand their focus to address longer-term mental health impacts of pandemics and economic crises. Such an approach could help support young people's future life chances and break the vicious cycle between mental illness and poverty that spirals many young people into both socioeconomic and mental health disadvantage.
