Objective: To evaluate vaccination coverage and delay in vaccine dose administration in infants in six municipalities in the Southern region of Brazil., Methodology: National Vaccination Coverage Survey 2020, with infants born alive in 2017 and 2018, carried out from September 2020 to March 2022. Coverage of doses administered, doses administered on time and delay in dose administration were evaluated., Results: For 4681 infants analyzed, coverage for vaccines recommended up to 24 months was 68.0% (95%CI 63.9;71.8%) for doses administered and 3.9% (95%CI 2.7%;5.7%) for doses administered on time. Delay time for the majority of late vaccinations was ≤ 3 months. For some boosters, 25% of vaccine administration was delayed by ≥ 6 months., Conclusion: In addition to tracking vaccine defaulters, strategies are needed to encourage compliance with the vaccination schedule at the recommended ages., Main Results: Vaccination coverage for the set of vaccines recommended up to 24 months was 68.0% and 3.9% for on-time doses. Delay time for some doses exceeded six months in up to 25% of infants with delayed vaccination., Implications for Services: Monitoring vaccine administration at the recommended ages is necessary, with the adoption of strategies that reinforce routine vaccination to prevent vaccination delays and abandonment., Perspectives: Primary care in surveillance and care for infants needs to reinforce actions to ensure timely vaccination. Studies to deepen knowledge of vaccination delay, determinants and strategies for their reduction are necessary.

Objective: To describe the polio vaccination status in 26 state capitals, the Federal District, and 12 municipalities in Brazil, among children born between 2017 and 2018., Methods: This was a population-based household survey conducted from 2020 to 2022, which assessed polio vaccination coverage in children, considering valid, administered, and timely doses by municipality., Results: Data were collected from 37,801 children. Vaccination coverage for the complete valid dose schedule was 87.5% (95%CI 86.2;88.7), dropping to 79.6% (95%CI 78.1;81.0), when the booster dose was considered. The dropout rate was 4.5% for the complete schedule, and 11.7% for the first booster. There was no correlation between campaign implementation and high coverage., Conclusion: Vaccination coverage for the complete valid dose schedule and the first booster did not meet the 95.0% target. Regional disparities and the association between vaccination coverage and social indicators should be taken into consideration in strategies to increase coverage.

Objective: To estimate prevalence of the full vaccination schedule for children 12 to 24 months old and to analyze associated factors., Methods: Survey with cluster sampling carried out in Vitória, Espírito Santo, Brazil, between December 16, 2020, and January 4, 2021. Children born in Vitória in 2017 and 2018 were included. We estimated the prevalence of vaccination schedules. Poisson regression was used to verify association with full vaccination coverage., Results: We included 788 children. Full vaccination coverage was found to be 57% taking a 95% confidence interval (95%CI 50.98;62.98). Prevalence of full vaccination coverage was lowest when private services were used for immunization (prevalence ratio [PR] 0.67; 95%CI 0.51;0.86) and when mothers had ≥ 4 children (PR 0.55; 95%CI 0.32;0.94)., Conclusion: We found low vaccination coverage and a drop in booster doses. Use of private services for immunization and number of children were associated with incomplete vaccination coverage.

Objective: To estimate and compare vaccination coverage among children born in 2017-2018 in São Paulo and Campinas, according to the Vaccination Coverage Survey (ICV 2020) and the National Immunization Program Information System (SI-PNI)., Methods: ICV 2020 analyzed vaccination card records. Coverage was calculated and compared to doses recorded on the SI-PNI, divided by the target population., Results: In São Paulo, according to ICV, in 2017 only BCG (91.7%; 95%CI 87.0;94.7) and rotavirus first dose (90.6%; 95%CI 86.5;93.5) achieved the goals; in 2018, BCG (93.4%; 95%CI 89.5;95.8), rotavirus first dose (90.5%; 95%CI 85.3;94.0), pneumococcal first dose (95.3%; 95%CI 91.7;97.4), meningococcal C first dose (95.1%; 95%CI 91.5;97.2) and pneumococcal second dose (95.0%; 95%CI 91.4;95.0). In Campinas, only BCG achieved the target in 2017 (93.0%; 95%CI 88.8;95.7) and none in 2018. According to the SI-PNI, no vaccine achieved the target in either city., Conclusion: Vaccination coverage was lower than expected and more precise estimates are necessary for adequate monitoring of childhood vaccination status.

Objective: To analyse vaccination coverage and factors associated with incomplete polio vaccination in a cohort of children born in 2017-2018, in state capitals and interior region municipalities of Northeast Brazil., Methods: Household survey of children aged ≤24 months conducted between 2020 and 2022. Vaccination coverage and dropout rates were estimated, as well as factors associated with incomplete vaccination, analyzed by calculating odds ratios (OR) and 95% confidence intervals (95%CI)., Results: : Among 12,137 children, vaccination coverage (4 doses) was 80.9% (95%CI 78.4;83.1); 8.4% were not vaccinated. Not having a vaccination card (OR=18.06; 95%CI 10.01;32.61) and use of private services (OR=1.46; 95%CI 1.23;1.74) were associated with incomplete vaccination. Higher dropout rates were found for the booster dose, especially in the highest stratum., Conclusion: Low vaccination coverage, poor dose follow-up and high dropout rates were found for polio vaccines in the areas studied.

Objective: To analyze vaccine hesitancy associated factors and repercussions on vaccination coverage., Methods: Cohort of children born in 2017-2018, living in Brazilian state capitals, Federal District (FD), and 12 inner region cities, stratified by socioeconomic level. National Vaccination Coverage Survey (2020) data on hesitancy, access and programmatic difficulties were obtained by interview and coverage was calculated from vaccination card dose and date records., Results: 37801 children were studied, 31001 in the capitals/FD, 6800 in the inner cities. Hesitation between 38.8(95%CI 33.6;44.4) and 57.9(95%CI 54.1;61.6) in high versus low stratum; 64.1(95%CI 58.9;68.9) to 41.7(95%CI 38.4;45.8) among mothers with <8 years of schooling versus 16 years or more; 42.1(95%CI 38.2;46.2) to 55.0(95%CI 52.0;54.7) among private service users versus public service only users. Coverage: full=7.2(95%CI 1.0;38.3); 25.3(95%CI 18.7;33.3) for hesitant people; and 44.7(95%CI 43.0;46.4) for the remainder., Conclusion: High vaccine hesitancy in several groups affecting vaccination coverage and hindering vaccination target achievement. Access problems and programmatic difficulties contribute to low coverage.

Objective: To evaluate opportunity for vaccination in children born alive in Londrina, up to 6 months old and the relationship between socioeconomic stratum and vaccination regularity., Method: Population survey study based on a retrospective cohort of children born in 2017 and 2018 that identified vaccines not administered in a given session. Vaccination regularity was compared between socioeconomic strata using Pearson's chi-square test., Results: Out of 456 vaccination cards, the proportion of vaccination opportunities not recovered for doses to be administered at birth and at two, four and six months was 5.0% (95%CI 3.1;7.5), 4. 5% (95%CI 2.8;6.9), 7.2% (95%CI 5.0;10.2) and 2.1% (95%CI 1.0;4.0), respectively. There was no statistical difference in vaccination regularity between the strata., Conclusion: Missed opportunities for vaccination were found at all ages. Socioeconomic stratum did not influence vaccination regularity.

Objective: To analyze vaccination coverage and factors associated with incomplete vaccination in inland municipalities of Northeastern Brazil., Methods: This was a household survey using cluster sampling conducted in Vitória da Conquista, Bahia state, Caruaru, Pernambuco state, Sobral, Ceará state and Imperatriz, Maranhão state between 2020 and 2022. Vaccination coverage by valid doses and vaccine hesitancy were analyzed, with the odds ratio (OR) estimated and adjusted using logistic regression., Results: Among 1,847 children, complete vaccination coverage was 49.2% (95%CI 43.9;54.5). Factors associated with incomplete vaccination included: higher income (OR 1.53; 95%CI 1.02;2.31), residence in Sobral (OR 4.35; 95%CI 3.04; 6.21) and >1 child (OR 1.20; 95%CI 1.11;1.32). Parental decision not to vaccinate and difficulties in traveling to vaccination centers contributed to vaccine hesitancy., Conclusion: Low vaccination coverage and incomplete vaccination were associated with social issues in the socioeconomic strata analyzed.

Objective: To estimate measles-mumps-rubella vaccination coverage, delay and loss to follow-up in children up to 24 months old living in Brazilian cities., Methods: Surveys and questionnaires with a retrospective cohort of live births in 2017-2018, analyzing vaccination coverage and sociodemographic data of children and families, based on vaccination card records and interviews., Results: Valid coverage of first dose was 90.0% (95%CI 88.9;91.0) and 81.1% for the second dose (95%CI 79.8;82.4). Delay for both doses was 23.2% (95%CI 21.9;24.5) and loss to follow-up was 10.8% (95%CI 9.9;11.8). Socioeconomic stratum A had the lowest vaccination coverage and the higher the child's birth order, the lower the vaccination coverage for the second dose. Children whose mothers had 13 to 15 years of education had higher vaccination coverage., Conclusion: Coverage did not meet the recommended target. Differentiated strategies to resolve difficulties in access, misinformation, and vaccination hesitancy will help improve vaccination coverage.

Objective: To estimate vaccination coverage and analyze factors associated with full vaccination among children up to 15 months old in the city of Natal-RN, Brazil., Methods: Population-based survey with data recorded on children's vaccination cards and interviews conducted in 2020 and 2021. Analysis of factors associated with complete vaccination was performed by calculating prevalence ratios (PR) and 95% confidence intervals (95%CI) using Poisson regression., Results: Among 688 children studied, vaccination coverage was 45.4% (95%CI 37.2;53.9) and 15.5% (95%CI 10.6;22.2) for valid and on-time doses, respectively. Higher vaccination coverage was associated with females (PR=1.08; 95%CI 0.78;1.48) and socioeconomic strata C and D (PR=1.44; 95%CI 1.03;2.02)., Conclusions: The results demonstrate that the city of Natal has low vaccination coverage for all immunobiologicals.

Objective: To analyze measles, mumps, and rubella vaccination coverage among children up to 24 months old and factors associated with non-vaccination in a 2017-2018 live birth cohort, in state capitals and large interior region cities in Northeast Brazil., Methods: Population-based survey analyzing vaccination coverage and sociodemographic factors through logistic regression., Results: For 12,137 children, vaccination coverage was 79.3% (95%CI 76.5;81.8), and the dropout rate was 10.6%. Association with non-vaccination: socioeconomic stratum A (OR-a 1.29; 95%CI 1.10;1.50), living in the interior region (OR-a 1.22; 95%CI 1.07;1.39), no access to the Bolsa Família Program (OR-a 1.19, 95%CI 1.05;1.34), family income ≤BRL 1,000 (OR-a 1.17, 95%CI 1.03;1.31), mother not working (OR-a 1.28, 95%CI 1.15;1.42), >1 child per mother (OR-a 1.12, 95%CI 1.08;1.17), and no vaccination card (OR-a 10.69, 95%CI 6.27;18.20)., Conclusion: Low vaccination coverage and a high dropout rate in state capitals and municipalities in the interior region of Northeast Brazil., Main Results: 79.3% vaccination coverage with incomplete vaccination associated with living in higher socioeconomic strata and in interior region municipalities, and children without vaccination records. High dropout rates in the state capitals Natal and João Pessoa., Implications for Services: Recognition of low coverage and factors associated with non-vaccination provides health services with relevant information with a view to planning strategic actions to increase measles, mumps and rubella vaccination coverage., Perspectives: Low coverage and identification of non-vaccination indicate the importance of targeting actions in the Brazilian National Health System to achieve the targets recommended by the National Immunization Program, for populations in Northeast Brazil.

Objective: To analyze factors associated with full vaccination coverage with valid doses, in children from four state capitals and three other cities in Southeast Brazil., Method: Analysis of a population survey conducted in 2020-2021, with a sample stratified according to socioeconomic levels of children born in 2017-2018, with data collected through photographic records of their vaccination cards. Odds ratios (OR) and 95% confidence intervals (95%CI) for full vaccination coverage were estimated based on the characteristics of the family, mother and child., Results: Among 8703 children, lowest coverage occurred in strata A and B (OR=0.39; 95%CI 0.23;0.67 and OR=0.38; 95%CI 0.25;0.58); in consumption level A/B (OR=0.38; 95CI% 0.28;0.52); among those with income >BRL8000/month (OR=0.23; 95%CI 0.12;0.42); in children of mothers with higher education (OR=0.47; 95%CI 0.32;0.71); in children not vaccinated exclusively in the public service (OR=0.37; 95%CI 0.26;0.51) and in children with a vaccination delay of up to 6 months (OR=0.28; 95%CI 0.22;0.37)., Conclusion: Coverage did not reach the targets for controlling vaccine-preventable diseases and was negatively associated with higher socioeconomic status., Main Results: Vaccination coverage for the full schedule with valid doses was very low, putting the control of vaccine-preventable diseases at risk in the four state capitals and three other cities in the interior region of Southeast Brazil., Implications for Services: Brazilian National Health System managers and workers need to know the factors associated with low vaccination coverage and increased risk of abandoning the schedule, access problems and National Immunization Program difficulties., Perspectives: Understanding determinants of low vaccination coverage provides support for the discussion and design of effective public policies to address barriers and qualify health services for vaccination.

Objective: To analyze vaccination coverage up to 24 months of age according to race/ skin color in the 2017-2018 live birth cohort in Natal, Rio Grande do Norte, Brazil., Methods: Population-based survey conducted in 2020 and 2021. Vaccination coverage up to 24 months of age was estimated according to administered, valid and timely doses. Crude association of race/skin color was estimated by calculating the crude Prevalence Ratio and respective 95% Confidence Intervals, using Poisson regression., Results: Of the 688 children in the selected cohort, there was greater coverage among Black children for administered doses (White 30.5%; Black 47.8%; 95%CI) and valid doses (White 25.8%; Black 40.1%; 95%CI), although without statistical significance, and lower coverage for timely doses, in the full schedule excluding yellow fever (PR = 0.21; 95%CI 0.04;0.90)., Conclusion: There was lower timely coverage among Black children compared to White children., Main Results: It was found that racial inequalities and social disparities were reflected in vaccination coverage of Black children in the state of Rio Grande do Norte, showing lower prevalence of timely and full vaccination schedules among those children., Implications for Services: The results demonstrate the need to strengthen equitable public policies and the implementation of practices that seek to improve vaccination coverage, thus reducing racial inequalities in child immunization., Perspectives: Health service managers will be able to plan actions and strategies in childhood immunization services, in order to increase vaccination coverage and reduce vaccination hesitancy among Black people and people from lower socioeconomic strata.

Objective: To describe timely vaccination completion and obstacles in the first 24 months of life in Brazil, examining associations with maternal race/skin color., Methods: Study participants were 37,801 children born in 2017 and 2018 included in the National Immunization Coverage Survey. We calculated prevalence and 95% confidence intervals for timely vaccine completeness and obstacles at 5, 12 and 24 months of life, according to maternal race/skin color. Associations were analyzed using logistic regression., Results: 7.2% (95%CI 6.3;8.2) of mothers faced difficulties in taking their children to be vaccinated, and 23.4% (95%CI 21.7;25.1) were not vaccinated when taken. These proportions were 75% (95%CI 1.25;2.45) and 97% (95%CI 1.57;2.48) higher, respectively, among Black mothers. At least one vaccination was delayed among 49.9% (95%CI 47.8;51.9) and 61.1% (95%CI 59.2;63.0) of children by 5 and 12 months, respectively. These rates were higher among Black/mixed race mothers., Conclusion: There are racial inequalities in both the obstacles faced and in vaccination rates in Brazil., Main Results: Marked racial inequalities were found in the obstacles to vaccination of children under 24 months in Brazil and to timely vaccination at 5 months and in the first year of life., Implications for Services: Racial inequalities in the occurrence of vaccination shortcomings in health services, in the objective restrictions faced by families in taking their children to vaccination centers and in incomplete vaccination in a timely manner need to be addressed by the Brazilian National Health System., Perspectives: Equal public policies to address barriers to vaccination and qualification of health services need to be implemented. Studies need to deepen understanding of the structural determinants that lead to racial disparities.

Objective: To estimate vaccination coverage, identify barriers and hesitancy to vaccinating children up to 24 months, born between 2017-2018, living in the urban area of Rio Branco, Acre, Brazil., Methods: Population survey carried out from 2020 to 2021, which assessed sociodemographic characteristics and vaccination status among children., Results: Among 451 included children, vaccination coverage was below 80%. Meningococcal C vaccine had the lowest coverage for administered doses (76.3%; 95%CI 70.5;81.3) and doses on time (27.4%; 95%CI 23.1;32.1). The statements "vaccines cause serious adverse reactions" (26.4%; 95%CI 18.1;36.8) and "you don't need vaccination for diseases that no longer exist" (22%; 95%CI 15.7;29.8) were the most frequent regarding vaccination hesitancy. Lack of vaccines was the main barrier to care (86.6%; 95%CI 71.8;94.3)., Conclusion: Vaccination coverage in children born in 2017-2018 was below the target recommended for the full schedule of administered doses, both valid and timely administered.

Objective: To estimate vaccination coverage and analyze sociodemographic factors associated with non-vaccination in children born in 2017 and 2018 in the state capitals of Northeast Brazil., Methods: A household survey using cluster sampling was conducted from 2020-2022 to estimate vaccination coverage and hesitancy. Factors associated with non-vaccination were analyzed using logistic regression to calculate Odds Ratios (OR) and their Confidence Intervals (95%CI)., Results: Natal was the capital with the lowest vaccination coverage, below 75.0% for most immunizers. Teresina had rates equal to or greater than 90.0% for all vaccines. Among those interviewed, 99.1% (95%CI 98.9;99.3) believe that vaccines are important for health; 95.4% (95%CI 95.0;95.8) trust immunobiologicals and 79.6% (95%CI% 78.8;80.3) are not afraid of reactions. Belonging to the highest socioeconomic stratum (adjusted OR: 1.34 - 95%CI 1.20;1.50) was as a factor associated with non-vaccination., Conclusion: Low coverage highlights the need for a better understanding of regional specificities and social inequalities.

Objective: To characterize the use of private services in infant vaccination and assess vaccination coverage according to the service used., Methods: : This was a national vaccination survey conducted in 2020 that estimated the use of private vaccination services and vaccination coverage among infants residing in state capitals and 12 inland municipalities., Results: : Of the 37,801 participants, 25.1% (95%CI 23.2;27.2) used private services at least once, with higher proportions in capitals, larger cities and in the South and Southeast regions. Socioeconomic and demographic differences were identified among families, based on the service used. The coverage for the set of vaccines administered up to 24 months was 60.3% (95%CI 58.6;62.0) in the public service and 59.5% (95%CI 55.9;63.0) in private services, and up-to-date vaccines, 10.3% (95%CI 9.1;11.6) and 9.4% (95%CI 7.4;11.8), respectively., Conclusion: The use of private services was frequent, with low coverage for the set of vaccines, regardless of the type of service used, especially for up-to-date vaccines.

Objective: To estimate vaccination coverage in children born between 2017-2018, living in urban areas of state capitals, the Federal District and 12 inland municipalities in Brazil, and to identify associated factors., Methods: This was a household survey conducted between 2020-2022, among children up to 24 months old. Vaccination coverage was estimated according to family, maternal and child characteristics., Results: Among the 37,801 children in the sample, complete coverage (doses administered) was 60.1% (95%CI 58.6;61.6) and 6.1% (95%CI 5.4;7.0) had not received any vaccines. Coverage was lower among children of mothers with lower level of education (OR = 0.70; 95%CI 0.54;0.90) and in those who experienced delays in receiving any vaccine by 6 months old (OR = 0.28; 95%CI 0.24;0.32)., Conclusion: Vaccination coverage is below the expected levels. Effective communication strategies are needed to reinforce the importance of routine vaccination, prevent delays and abandonment of the vaccination schedule, in order to recover the high coverage levels achieved in past decades.

Objective: To analyze full vaccination coverage in live births in 2017 and 2018 in the capitals of the Midwest region of Brazil, according to social strata., Methods: Population-based household survey with cluster sampling. Full coverage in children at 12 and 24 months of age and sociodemographic factors were analyzed., Results: 5,715 children were analyzed. Full coverage at 12 months of age was 67.9% (95%CI 65.4;70.4), while at 24 months it was 48.2% (95%CI 45.3;51.1). Pneumococcal vaccine had the highest vaccination coverage (91.3%), while the second dose of rotavirus vaccine had the lowest (74.2%). In Campo Grande, no vaccine reached coverage above 90%, with BCG (82.9%) and hepatitis B (82.1%) standing out. Campo Grande and Brasília had the worst vaccination coverage in the high social stratum (24 months of age)., Conclusion: Vaccination coverage in the Midwest was below 80%, falling short of the recommended target and associated with socioeconomic factors.

Objective: To analyze the reliability of records held on the National Immunization Program Information System (SI-PNI) in a subsample of children included in the national vaccination coverage survey in Brazilian state capitals and Federal District in 2020., Methods: This was a study of agreement between data recorded on vaccination cards (doses and dates) and on the SI-PNI for 4050 children with full coverage at 24 months., Results: Data on 3587 children were held on the SI-PNI, with losses of 11% (95%CI: 10;12). Total agreement between doses and dates in the two sources was 86% (95%CI: 86;87), however taking each dose and vaccine individually, variation was greater, with 32% of data in only one source., Conclusion: Part of the information was not recorded, but the discrepancy can be considered small. Nonetheless, underrecording of doses and children can compromise vaccination coverage estimates, altering the numerator and denominator data., Main Results: Subsample of 4,050 children, among those completing the full schedule at 24 months studied in the national survey, 11% had not been recorded on the SI-PNI, 32% had unrecorded doses (doses or dates) and there was 8% disagreement between vaccination cards and SI-PNI records., Implications for Services: Recognizing the difficulties faced by the SI-PNI and the discrepancies between sources is essential for adopting initiatives to improve data quality, so as to avoid inaccurate estimates of childhood vaccination coverage., Perspectives: This study is expected to contribute to improving the quality of records and the usability of data for monitoring vaccination coverage of the immunization program from the local to the national level.

Objective: To analyze vaccination coverage according to social strata in children up to 24 months old, living in the municipality of Londrina (PR), Brazil., Methods: This was a population-based survey conducted between 2021 and 2022, in which vaccination coverage and sociodemographic aspects of mothers and families were evaluated using Pearson's chi-square test., Results: In a sample of 456 children, complete vaccination coverage varied according to social strata, being 36.0% (95%CI 26.8;57.8); in stratum A; 59.5% (95%CI 26.1;86); in stratum B; 66.2% (95%CI 51.7;78.1); in stratum C; and 70.0% (95%CI 56.1;81.0) in stratum D., Conclusion: The analysis of vaccination coverage indicated that social stratum A is at highest risk for vaccine-preventable diseases., Main Results: The results of the study showed low full vaccination coverage in children up to 24 months of age in Londrina, being higher in the less financially advantaged social stratum, compared to the most advantaged., Implications for Services: The results found can support the qualification of the immunization program and enable, based on planning and ongoing health education, the definition of unique strategies to improve vaccination coverage., Perspectives: Future perspectives point to the importance of carrying out investigations into the challenges inherent to vaccination, as well as qualitative and quantitative research addressing health professionals to better understand the data.

Objective: To estimate hepatitis A vaccination coverage in 24-month-old children and identify factors associated with non-vaccination., Methods: This was a survey involving a sample stratified by socioeconomic strata in capital cities (2020-2022), with coverage estimates and 95% confidence intervals (95%CI), the factor analysis was performed using the prevalence ratio (PR) by means of Poisson regression., Results: Among 31,001 children, hepatitis A coverage was 88.1% (95%CI 86.8;89.2). Regarding socioeconomic strata (A/B), the variable immigrant parents/guardians was associated with non-vaccination (PR = 1.91; 95%CI 1.09;3.37); in strata C/D, children of Asian race/skin color (PR = 4.69; 95%CI 2.30;9.57), fourth-born child or later (PR = 1.68; 95%CI 1.06;2 .66), not attending daycare/nursery (PR = 1.67; 95%CI 1.24;2.24) and mother with paid work (PR = 1.42; 95%CI 1.16;1.74) were associated with non-vaccination., Conclusion: Hepatitis A coverage was below the target (95%), suggesting that specificities of social strata should be taken into consideration., Main Results: Hepatitis A vaccination coverage was 88%. Non-vaccination was greater in children with immigrant guardians (strata A/B); of Asian race/skin color, fourth-born child or later, those not attending daycare/nursery and mother with paid work (C/D strata)., Implications for Services: The results of this study contributed to the Ministry of Health and Health Departments in monitoring vaccination coverage and identifying factors that may negatively impact hepatitis A vaccination coverage., Perspectives: Further research is needed on the impact of migration on hepatitis A vaccination and vaccination in general. Health managers should be attentive to the different factors affecting vaccination among social strata.

Objectives: To evaluate the extent to which dental care factors in adulthood modify and, at the same time, mediate the association between race/ethnicity and social mobility from childhood to adulthood with two oral health outcomes in adults., Methods: In 2012, 1222 individuals 20-59 years old participated in the second wave of the Epi-Floripa Study in Florianopolis, Brazil. Exposures included social mobility based on adulthood and childhood events, dental care in previous years, type of dental care coverage, reason for dental visits and race. The number of missing and decayed teeth were dichotomised as MT >0 and DT >0., Results: The prevalence of missing and decayed teeth was 61.9% and 23.0%, respectively. Age-sex adjusted inequalities in decayed and missing teeth among Black and White individuals were 41.2 percentage points (pp) (95% CI: 3.9-78.7) and 53.1 pp (19.5:86.7), respectively. Inequalities between those persistently higher and lower in socioeconomic position were 42.6 pp (14.6-70.7) and 90.0 pp (62.1-100). The Relative Excess of Risk due to Interaction (RERI) was not statistically significant (p < 0.05). Oaxaca-Blinder decomposition analyses showed that dental care variables accounted for a small proportion of inequalities., Conclusions: This result implies that dental care is unlikely to significantly reduce or increase oral health inequalities in this particular population., (© 2024 Wiley Periodicals LLC.)

Objective: To describe vaccination coverage and hesitation for the basic children's schedule in Belo Horizonte and Sete Lagoas, Minas Gerais state, Brazil., Methods: Population-based epidemiological surveys performed from 2020 to 2022, which estimated vaccine coverage by type of immunobiological product and full schedule (valid and ministered doses), according to socioeconomic strata; and reasons for vaccination hesitancy., Results: Overall coverage with valid doses and vaccination hesitancy for at least one vaccine were, respectively, 50.2% (95%CI 44.1;56.2) and 1.6% (95%CI 0.9;2.7), in Belo Horizonte (n = 1,866), and 64.9% (95%CI 56.9;72.1) and 1.0% (95%CI 0.3;2.8), in Sete Lagoas (n = 451), with differences between socioeconomic strata. Fear of severe reactions was the main reason for vaccination hesitancy., Conclusion: Coverage was identified as being below recommended levels for most vaccines. Disinformation should be combated in order to avoid vaccination hesitancy. There is a pressing need to recover coverages, considering public health service access and socioeconomic disparities., Main Results: Vaccination coverage of children up to 4 years old was 50.2% in Belo Horizonte, and 64.9% in Sete Lagoas. Fear of severe reactions and believing that vaccination against eradicated diseases is unnecessary were the main reasons for vaccination hesitancy., Implications for Services: Recovery of high vaccination coverage among children, considering public health service access conditions and socioeconomic inequities. Acting on reasons for hesitancy that can assist in targeting actions., Perspectives: The multifactorial context of vaccination hesitancy demands the development of health education strategies to raise awareness about child immunization.

This study examined the spatial distribution and social inequalities in COVID-19 vaccine coverage among children aged 5-11 in Brazil. First and second dose vaccine coverage was calculated for all Brazilian municipalities and analyzed by geographic region and deciles based on human development index (HDI-M) and expected years of schooling at 18 years of age. Multilevel models were used to determine the variance partition coefficient, and bivariate local Moran's I statistic was used to assess spatial association. Results showed significant differences in vaccine coverage rates among Brazilian municipalities, with lower coverage in the North and Midwest regions. Municipalities with lower HDI and expected years of schooling had consistently lower vaccine coverage rates. Bivariate clustering analysis identified extensive concentrations of municipalities in the Northern and Northeastern regions with low vaccine coverage and low human development, while some clusters of municipalities in the Southeast and South regions with low coverage were located in areas with high HDI-M. These findings highlight the persistent municipal-level inequalities in vaccine coverage among children in Brazil and the need for targeted interventions to improve vaccine access and coverage in underserved areas.

Objectives: The understanding of how subjective socioeconomic status (SSS) relates to objective socioeconomic status (OSS), and how both conditions act together in oral health outcomes is still unclear. This study aims to test the independent and joint association between OSS and SSS with oral health, to assess the role of socioeconomic status discrepancies, and to evaluate the role of SSS in the association between OSS and oral health., Methods: Data from 1140 adults from a population-based study in Southern Brazil were used. We applied diagonal reference models DRM to disentangle the effects of OSS (education) and SSS (MacArthur Scale) to oral health outcomes. The outcomes were functional dentition clinically evaluated (FD ≥20 teeth) and self-reported oral health SROH. We also examined the discrepancy between OSS and SSS to oral health indicators and the effect measure modification (EMM) of SSS on the association between OSS and oral health., Results: Subjective socioeconomic status and OSS contributed equally to SROH, while OSS explained a substantially higher amount of FD than SSS (0.85 vs 0.15). An EMM of SSS was found on the association between OSS and fair/poor SROH, with a relative excess risk due to interaction (RERI) of 1.08. Less evidence of EMM was found for FD (RERI = 0.14). Individuals with lower SSS and OSS had four times the risk of the outcomes than the reference group., Conclusions: Adults with concordant lower SSS and OSS have a worse oral health than those with concordant higher status. There was evidence that the association between OSS and SROH is modified by SSS., (© 2021 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Objective: To analyze the prevalence evolution of Guthrie, hearing, and eye screening testing among newborns in Brazil, between 2013 and 2019, according to demographic and socioeconomic characteristics., Methods: This is a cross-sectional study with data from 5231 infants from the Pesquisa Nacional de Saúde (PNS), in 2013, and 6637 infants, in 2019, for the Guthrie test, hearing, and red reflex tests. The authors analyzed the outcomes according to the region of residence, self-reported color/race, having health insurance, and per capita household income. By using bivariate and multivariate Poisson regression models, the prevalence ratios and their respective 95 % Confidence Intervals (CI 95 % ) were calculated for each year., Results: In 2013, Guthrie test, hearing, and red reflex tests were performed in 96.5 % ( 95 % CI 95,8;97,0), 65.8 % ( 95 % CI 63,9;67,7), and 60.4 % ( 95 % CI 58,5;62,3) of infants, respectively. In 2019, the prevalence was 97.8 % ( 95 % CI 97,3;98,2) in the Guthrie test, 81.6 % ( 95 % CI 80,3;82,9) in the hearing test, and 78.6 % ( 95 % CI 77,1;79,9) in the red reflex test. The testing frequency was higher among residents of the Southeast and South regions of Brazil, among infants whose mother or guardian was white, had health insurance, and was in the higher income strata; and the most evident differences were in the eye and hearing testing., Conclusions: The coverage inequalities according to the region of residence, income, and having health insurance highlight the need to use strategies that enable exams to be carried out, with more information about their importance, encompassing actions from primary care, prenatal care to the puerperium, aiming at universal access and equity., Competing Interests: Conflicts of interest The authors declare no conflicts of interest., (Copyright © 2023 Sociedade Brasileira de Pediatria.

Introduction: eConsults are asynchronous digital communications for primary care professionals to seek timely specialist advice. Potential benefits include increased primary healthcare capacity and referral efficiency. Santa Catarina Telehealth Centre in Brazil has offered eConsults for an increasing number of specialties since 2008. This study described the characteristics of this service, including referral efficiency, sustainability, and satisfaction., Methods: Retrospective longitudinal analysis of eConsults activity data from 2015 to 2022 with three domains of the Model for Assessment of Telemedicine Applications used to structure the analysis., Results: Characteristics of the application : The total number of eConsults performed in 2015 was 4764, reaching 41,178 in 2022. While 30.3% of eConsults were synchronous in 2015, only asynchronous communication remained from 2021. Clinical effectiveness : eConsults requested to refer patients to specialist care resulting in primary care management remaining above 30% of the total for all specialties from 2019 to 2022, with hematology having the highest percentage (>52%). Organizational aspects : Established workflows with local specialists responding to eConsults (cardiology, endocrinology, hematology and orthopaedics) kept a constant or increasing number of eConsults and maintained the proportion of primary care management from 2019 to 2022, once recovered from COVID-19 and funding restrictions-related reductions. Over 90% of primary care professionals are either satisfied or very satisfied with the eConsult service., Conclusion: Over 8 years, 223,734 consultations were conducted, with high satisfaction, demonstrating the substantial potential for increased primary care-sensitive conditions management. Hiring local specialists, fostering integrated care, and enabling sustainable workflows are key to eConsults' success.

This study aims to assess the progress of geographic, socioeconomic, and demographic disparities in Covid-19 vaccination coverage in Brazil over the first two years of the vaccination campaign. Data from the National Immunization Program Information System were used to estimate covid-19 vaccine coverage. Brazilian municipalities were divided into two groups based on their vaccine coverage for the booster dose. The first group comprised 20% of municipalities with the lowest coverage, while the second group (80% of municipalities) had higher coverage. The analysis was conducted separately for four age groups: 5-11, 12-17, 18-59, and 60+. Explanatory variables included socioeconomic and health services indicators. Crude and adjusted logistic regression models were used to estimate the probability of a municipality being among those with the worst vaccination coverage according to the categories of exploratory variables. Between January/2021 and December/2022, Brazil administered 448.2 million doses of the covid-19 vaccine. The booster vaccination coverage varied from 24.8% among adolescents to 79.7% among the elderly. The difference between the group with the highest and lowest coverage increased during the national vaccination campaign. Municipalities with lower education levels, higher proportion of Black population, higher Gini index, and worse health service indicators had a greater likelihood of having lower vaccination coverage. High and increasing levels of inequality in Covid-19 vaccination were observed in Brazil across all age groups during the vaccination campaign in 2021-2022., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Boing et al.

Objective: The national vaccination coverage survey on full vaccination at 12 and 24 months of age was carried out to investigate drops in coverage as of 2016., Methods: A sample of 37,836 live births from the 2017 or 2018 cohorts living in capital cities, the Federal District, and 12 inner cities with 100 thousand inhabitants were followed for the first 24 months through vaccine record cards. Census tracts stratified according to socioeconomic levels had the same number of children included in each stratum. Coverage for each vaccine, full vaccination at 12 and 24 months and number of doses administered, valid and timely, were calculated. Family, maternal and child factors associated with coverage were surveyed. The reasons for not vaccinating analyzed were: medical contraindications, access difficulties, problems with the program, and vaccine hesitancy., Results: Preliminary results showed that less than 1% of children were not vaccinated, full coverage was less than 75% at all capitals and the Federal District, vaccines requiring more than one dose progressively lost coverage, and there were inequalities among socioeconomic strata, favorable to the highest level in some cities and to the lowest in others., Conclusion: There was an actual reduction in full vaccination in all capitals and the Federal District for children born in 2017 and 2018, showing a deteriorating implementation of the National Immunization Program from 2017 to 2019. The survey did not measure the impacts of the COVID-19 pandemic, which may have further reduced vaccination coverage.

Vaccination is crucial for reducing severe COVID-19 cases, hospitalizations, and deaths. However, vaccine access disparities within countries, particularly in low- and middle-income nations, may leave disadvantaged regions and populations behind. This study aimed to investigate potential inequalities in vaccine coverage among Brazilian aged 18 years and older based on demographic, geographic, and socioeconomic characteristics at the municipal level. A total of 389 million vaccination records from the National Immunization Program Information System were analyzed to calculate vaccine coverage rates for the first, second, and booster doses among adults (18-59 years) and elderly (60 + years) vaccinated between January 2021 and December 2022. We analyzed the data by gender and used a three-level (municipalities, states, regions) multilevel regression analysis to assess the association between vaccine coverage and municipal characteristics. Vaccination coverage was higher among the elderly than among adults, particularly for the second and booster doses. Adult women showed higher coverage rates than men (ranging from 118 % to 25 % higher along the analyzed period). Significant inequalities were observed when analyzing the evolution of vaccination coverage by sociodemographic characteristics of municipalities. In the early stages of the vaccination campaign, municipalities with higher per capita Gross Domestic Product (pGDP), educational level, and fewer Black residents reached higher population coverages earlier. In December 2022, adult and elderly booster vaccine coverage was 43 % and 19 %, respectively, higher in municipalities in the highest quintile of educational level. Higher vaccine uptake was also observed in municipalities with fewer Black residents and higher pGDP. Municipalities accounted for most of the variance in vaccine coverage (59.7 %-90.4 % depending on the dose and age group). This study emphasizes the inadequate booster coverage and the presence of socioeconomic and demographic disparities in COVID-19 vaccination rates. These issues must be addressed through equitable interventions to avoid potential disparities in morbidity and mortality., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

SARS-CoV-2 genome surveillance is important for monitoring risk groups and health workers as well as data on new cases and mortality rate due to COVID-19. We characterized the circulation of SARS-CoV-2 variants from May 2021 to April 2022 in the state of Santa Catarina, southern Brazil, and evaluated the similarity between variants present in the population and healthcare workers (HCW). A total of 5291 sequenced genomes demonstrated the circulation of 55 strains and four variants of concern (Alpha, Delta, Gamma and Omicron-sublineages BA.1 and BA.2). The number of cases was relatively low in May 2021, but the number of deaths was higher with the Gamma variant. There was a significant increase in both numbers between December 2021 and February 2022, peaking in mid-January 2022, when the Omicron variant dominated. After May 2021, two distinct variant groups (Delta and Omicron) were observed, equally distributed among the five Santa Catarina mesoregions. Moreover, from November 2021 to February 2022, similar variant profiles between HCW and the general population were observed, and a quicker shift from Delta to Omicron in HCW than in the general population. This demonstrates the importance of HCW as a sentinel group for monitoring disease trends in the general population.

Objective: To analyze the association of hospital case fatality rate and care received by children and adolescents hospitalized for COVID-19 with the gross domestic product (GDP) per capita of Brazilian municipalities and regions of residence., Methods: Data were collected from the Influenza Epidemiological Surveillance Information System and the Brazilian Institute of Geography and Statistics. The dichotomous outcomes analyzed were hospital case fatality rate of COVID-19, biological samples collected for COVID-19 diagnosis, X-rays, computed tomography (CT) scans, use of ventilatory support, and intensive care unit hospitalization. The covariates were municipal GDP per capita and the Brazilian region of residence. Poisson regression was used for the outcomes recorded in 2020 and 2021 in Brazil, covering the two COVID-19 waves in the country, adjusted for age and gender., Results: The hospital case fatality rate was 7.6%. In municipalities with lower GDP per capita deciles, the case fatality rate was almost four times higher among children and twice as high in adolescents compared to cities with higher deciles. Additionally, residents of municipalities with lower GDP per capita had fewer biological samples collected for diagnosis, X-ray examinations, and CT scans. We found regional disparities associated with case fatality rate, with worse indicators in the North and Northeast regions. The findings remained consistent over the two COVID-19 waves., Conclusion: Municipalities with lower GDP per capita, as well as the North and Northeast regions, had worse indicators of hospital case fatality rate and care.

The study aims to analyze inequalities in Covid-19 outcomes in Brazil in 2020/2021 according to the per capita Gross Domestic Product (pcGDP) of municipalities. All cases of Severe Acute Respiratory Syndrome (SARS) who were hospitalized or died, regardless of hospitalization, registered in Brazil in 2020 and 2021 were analyzed (n = 2,902,742), including those with a confirmed diagnosis of Covid-19 (n = 1,894,165). We calculated lethality due to Covid-19, the performance of diagnostic tests among patients with SARS, and the hospital care received by those with Covid-19 according to the pcGDP of the patients' municipalities of residence. Data were analyzed for each epidemiological week and the risk of each outcome was estimated using Poisson regression. Municipalities in the lowest pcGDP decile had (i) 30% (95%CI 28%-32%) higher lethality from Covid-19, (ii) three times higher proportion of patients with SARS without the collection of biological material for the diagnosis of Covid-19, (iii) 16% (95%CI 15%-16%) higher proportion of SARS patients testing in a period longer than two days from the onset of symptoms, (iv) 140% (95%CI 134%-145%) higher absence of CT scan use. There is deep socioeconomic inequality among Brazilian municipalities regarding the occurrence of Covid-19 negative outcomes., Competing Interests: Declaration of interests The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022.

The study aimed to analyze and compare the prevalence of access to medicines and associated factors among users of the Brazilian Unified National Health System (SUS). The authors analyzed data from the 2013 and 2019 editions of the Brazilian National Health Survey, a nationwide health study, representative of the Brazilian population. The outcomes were: (1) obtaining from the SUS all the medicines prescribed during care received in the SUS itself in the two weeks prior to the interview (2) and obtaining all the medicines, regardless of the source. Demographic and socioeconomic characteristics were included as independent variables. In 2019, 29.7% of the interviewees obtained all the prescribed medicines from the SUS, 81.8% obtained all the medicines in general (considering all sources), and 56.4% paid some amount for the medicines. The proportion who did obtain any medicine from the SUS and that made some out-of-pocket payment increased from 2013 to 2019. The likelihood of obtaining all the medicines in the SUS was higher among the poorest, and that of obtaining the medicines regardless of source was higher among the wealthiest. Approximately two out of three persons that were unable to access all the medicines reported difficulties obtaining them in services funded by the public sector. There was an increase in out-of-pocket expenditure on medicines in Brazil and a reduction in access through the SUS, among users of the system.

Importance: Prior studies on the association between fine particulate matter with diameters 2.5 μm or smaller (PM2.5) and probability of death have not applied multilevel analysis disaggregating data for US census tract, states, and counties, nor tested its interaction by socioeconomic status (SES). Such an approach could provide a more refined identification and targeting of populations exposed to increased risk from PM2.5., Objective: To assess the association between PM2.5 and age-specific mortality risk (ASMR) using disaggregated data at the census tract level and evaluate such association according to census tract SES., Design, Setting, and Participants: This nationwide cross-sectional study used a linkage of 3 different data sets. ASMR for the period of 2010 to 2015 was obtained from the National Center for Health Statistic, SES data covering a period from 2006 to 2016 came from the American Community Survey, and mean PM2.5 exposure levels from 2010 to 2015 were derived from well-validated atmospheric chemistry and machine learning models. Data were analyzed in April 2021., Exposures: The main exploratory variable was mean census tract-level long-term exposure to PM2.5 from 2010 to 2015., Main Outcomes and Measures: The primary outcome was census tract-level ASMR. Multilevel models were used to quantify the geographic variation in ASMR at levels of census tract, county, and state. Additional analysis explored the interaction of SES in the association of ASMR with PM2.5 exposure., Results: Data from 67 148 census tracts nested in 3087 counties and 50 states were analyzed. The association between exposure to PM2.5 and ASMR varied substantially across census tracts. The magnitude of such association also varied across age groups, being higher among adults and older adults. Census tracts accounted for most of the total geographic variation in mortality risk (range, 77.0%-94.2%). ASMR was higher in deciles with greater PM2.5 concentration. For example, ASMR for age 75 to 84 years was 54.6 per 1000 population higher in the decile with the second-highest PM2.5 concentration than in the decile with the lowest PM2.5 concentration. The ASMR, PM2.5 concentrations, and magnitude of the association between both were higher in the census tracts with the lowest SES., Conclusions and Relevance: This cross-sectional study found that census tracts with lower SES presented higher PM2.5 concentrations. ASMR and air pollution varied substantially across census tracts. There was an association between air pollution and ASMR across all age groups in the United States. These findings suggest that equitable public policies aimed at improving air quality are needed and important to increase life expectancy.

Scientific journals play a fundamental role in the development of science. However, in Brazil, there are major challenges for their sustainability, as well as for the sustainability of the SciELO Program. The article reports a worrying scenario of low public funding and lack of strategic planning for long-term funding for scientific publication, contrary to the development of Brazilian journals and the SciELO Program. This scenario places great pressure on journals, with reports of situations of closure of activities, or implementation of fees charged to authors, while bringing financial insecurity to the SciELO Program. The actions taken by Brazilian scientific societies and the position of the Forum of Editors of Public Health Journals are aligned with that of the Advisory Committee of the SciELO Brazil Collection, namely that the publication of scientific journals edited in Brazil is strategic and, therefore, should be fostered through public policies and supported with public financing from the sponsoring institutions and grants from the research funding institutions.

The scope of this study was to analyze the prevalence and the factors associated with sufficient leisure-time physical activity (LTPA) among Brazilians diagnosed with hypertension, diabetes and/or hypercholesterolemia. It involved a representative, cross-sectional population-based study for the entire Brazilian territory. Adults aged 20 years and over were interviewed. Prevalences were estimated and, by means of logistic regression, the crude and adjusted odds ratios (OR) of the outcome were calculated in accordance with each of the exploratory variables. The prevalence of sufficient LTPA was 15.9%, 15.3% and 21.4% among people with hypertension (n=12,228), diabetes (n=3,577) and hypercholesterolemia (n=7,124), respectively. These values were lower than those observed among adults who did not report one of the three diseases. Adjusted analysis showed that individuals with positive self-perception of health and with more schooling, who reported a public space near their homes for physical activity, the existence in the city of public programs that encourage physical activity and the recommendation of health professionals to practice LTPA, were associated with a greater chance of being sufficiently active.

Objective: Test the association between the practice of physical activity (PA) according to the gestational trimesters and the occurrence of cesarean delivery, prematurity, and low birth weight in puerperal women assisted in the Unified Health System of Santa Catarina, Brazil., Methods: A cross-sectional study was conducted with a probabilistic sample of puerperal women who gave birth in public maternity hospitals in Santa Catarina from January to August 2019. The cesarean delivery outcome was self-reported, and information on premature birth (< 37 gestational weeks) and low birth weight (< 2,500 grams) were obtained from medical records. The practice of PA during pregnancy and according to each trimester was self-reported. Multivariate Logistic Regression analyses and interviews with 3,580 puerperal women were carried out., Results: PA practice during any period of pregnancy was reported by 20.6% of the sample, with a gradual reduction in prevalence according to the gestational trimester (16.2%, 15.4%, and 12.8%). The highest prevalences of outcomes concerning the total sample were observed in puerperal women who did not practice PA in the third trimester, with 43.9% for cesarean delivery, 7.7% for low birth weight, and 5.5% for premature birth. The odds of cesarean delivery (OR = 1.40; 95%CI 1.10-1.76) and low birth weight (OR = 1.99; 95%CI 1.04-3.79) were, respectively, 40% and 99% higher among puerperal women who did not practice PA in the third trimester of pregnancy when compared to those who practiced PA. There was no association between PA practice and prematurity., Conclusion: Puerperal women who did not practice PA in the third trimester of pregnancy were more likely to have cesarean delivery and low birth weight newborns.

To investigate the association between deficient and insufficient serum concentrations of 25(OH)D and cardiometabolic risk factors (CMRF), considering that both conditions are important predictors of cardiovascular disease and diabetes mellitus. A cross-sectional study with a subsample of 526 older adults (63-93 years old) who participated in the second wave of the population-based longitudinal study EpiFloripa Idoso . The CMRF analyzed were abdominal obesity, high fasting glucose, high blood pressure, high triglycerides and high LDL-cholesterol. The exposure variable was 25(OH)D serum concentration (≤20 ng/mL = deficient; 21-29 ng/mL = insufficient, ≥30-<100 ng/mL = sufficient). The prevalences of 25(OH)D deficiency and insufficiency were estimated at 21.9% and 43.7%, respectively. The adjusted OR of prevalence of the abdominal obesity (OR 1.99;1.12-3.54), high blood pressure (OR 2.58;1.35-4.94) and high LDL-cholesterol (OR 2.73;1.63-4.6) were higher among those with deficient serum concentration of 25(OH)D. Participants with insufficient serum concentrations of 25(OH)D also presented higher adjusted OR of prevalence for abdominal obesity (OR 2.14;1.31-3.48). No significant adjusted association was found between 25(OH)D with the outcomes high fasting glucose and high triglycerides. Significant effect modification/interaction by age was also observed in the tested associations for abdominal obesity (P < 0.001), blood pressure (P < 0.001) and LDL-cholesterol (P < 0.001), in which deficient and insufficient 25(OH)D values were associated with higher values of these FRCM. 25(OH)D serum concentrations between 30 and 100 ng/mL can contribute to preventing and controlling CMRF such as abdominal obesity, high blood pressure and high LDL-cholesterol. The understanding this particular interaction may indicate ways to prevent/control cardiometabolic outcomes, health problems common in the older adults., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2021 The Author(s).)

Objective: to analyze the association between individual characteristics and housing context with smoking and alcohol consumption during pregnancy., Methods: a cross-sectional study with a probabilistic sample of 3,580 pregnant women who underwent prenatal care in the Unified Health System in 2019. The outcomes were firsthand, secondhand smoke and alcohol consumption during pregnancy. Individual characteristics and the living environment were used as exploratory variables., Results: living in a neighborhood with episodes of violence, without social cohesion and without urban elements that encourage physical activity was associated with smoking. Alcohol consumption during pregnancy was associated with living in environments that do not encourage physical activity. Smoking was also associated with lower income and education., Conclusions: individual characteristics and the living environment are associated with smoking, secondhand smoke and alcohol consumption during pregnancy.

This study aims (1) to test the association between access to basic sanitation/hygiene services in Brazilian households with their householders' socioeconomic and demographic characteristics; (2) to analyze the distribution of urban health-relevant elements in the census tracts according to their income, education and race/color composition. The information come from the 2010 Brazilian Demographic Census, which collected data regarding both household conditions and urban structure of the census tracts. Prevalence ratios were calculated using crude and adjusted Poisson regression models. The proportional distribution of the census-tract urban structure was performed, according to the deciles of the exploratory variables, and the ratios and the absolute differences between the extreme deciles were calculated. Around 4.8% of the households had no piped water, 34.7% had no sewage collection system, 9.8% had no garbage collection and 39% were considered inadequate. Families whose householders were black, indigenous or brown had lower income and educational level, and lived in the North, Northeast, and Central West regions. They were more likely to be considered inappropriate for not having piped water, sewage collection system, and garbage collection. Moreover, sectors where the majority of the population was black, had lower educational levels and lower income had significantly poor paving, street lighting, afforestation, storm drain, sidewalk and wheelchair ramp. This study analyzed national data from 2010 and provides a baseline for future studies and government planning. The relevant social inequalities reported in this study need to be addressed by effective public policies.

This article discusses the epidemic situation of Covid-19 in Brazil, in the face of the emergence of a new strain called P.1, which is more transmissible and may be associated with reinfection. Given the collapse of hospital care in Manaus in January 2021 and the results of three recent preprints, each that reports increased transmissibility of the P.1 variant, we propose some urgent measures. Genomic surveillance based on multi-step diagnostics, starting with RT-PCR type tests and up to sequencing, should be established. Efforts to identify reinfections associated with this variant and the update of its definition in protocols should be prioritized, and studies on the efficacy of currently available vaccines in Brazil concerning the new variant should be conducted. We also propose improving the Brazilian health surveillance system such that genomic surveillance is coordinated and thereby better able to respond to future emergencies in a more timely fashion. We call on the public agents involved in health surveillance to share data and information regarding the epidemic in a clear, fast and transparent way. Finally, we propose a greater engagement in inter-institutional cooperation of all those involved in the response and production of knowledge about the pandemic in our country.

Objective: To analyze the prevalence and factors associated with professional recommendation and leisure-time physical activity (LTPA) in Brazilian individuals diagnosed with hypertension (HBP), diabetes, and/or hypercholesterolemia., Methods: This is a cross-sectional population-based study with a representative sample of the Brazilian population (aged ≥20 years) in 2013, with self-reported HBP (n=11.098), diabetes (n=3.176), and/or hypercholesterolemia (n=7.252). Prevalence and gross odds ratios were estimated and adjusted for both outcomes., Results: Professional recommendation and LTPA were more prevalent in individuals who received recommendation and presented with hypercholesterolemia (85.9 and 23.4%, respectively). Adjusted analysis showed an association in people 40 to 59 years of age and public programs in most diseases. Higher educational level was associated with receiving recommendations in all non-communicable diseases (NCDs). LTPA was associated in people 40 to 59 years of age for HBP and diabetes and in all investigated NCDs, higher educational level, positive perception of health, and a favorable environment in those who received recommendation., Conclusions: Education presented the greatest magnitude in the associations, clearly showing the need for equitable methods to increase recommendation and LTPA levels for the most vulnerable population. Further studies analyzing other variables and NCD are needed, corroborating the Ministry of Health.

Tuberculosis remains a major public health problem deeply influenced by inequality. The present study used data from the Brazilian Tuberculosis Case Registry Database in order to compare the rates of tuberculosis treatment success, loss to follow-up, and tuberculosis mortality between the homeless population and the general population of Brazil. The likelihood of tuberculosis treatment success was reduced by approximately 50% in the homeless population. In addition, the rate of loss to follow-up was 2.9 times higher in the homeless population than in the general population, and the rate of tuberculosis mortality was 2.5 times higher in the former.

Objective: To describe the methodological and operational aspects of an epidemiological and an evaluation of Rede Cegonha in Santa Catarina, Brazil., Methods: The research carried out in 2019 was composed of two sub-studies. Regarding the first, whose design was epidemiological and analyzed prenatal, delivery and immediate puerperium care addressed to pregnant women, puerperal women and children assisted at SUS, the instruments used for data collection and the organization of the field of the study are described. The other sub-study was a normative assessment of municipal management in prenatal and postpartum care within the scope of Rede Cegonha. It began with an evaluability assessment followed by the assessment itself. The different methodological strategies adopted are described, with the involvement of stakeholders and experts., Results: The response rate of the epidemiological sub-study was 97.7%. Women residing in 82.7% of Santa Catarina's municipalities were interviewed. The sample was similar to that registered in SINASC for the same period, and the characteristics of the sub-sample interviewed after six months was similar to the global sample. The evaluation study improved and applied a model with 32 indicators that allowed to analyze the municipalities considering the political-organizational and tactical-operational aspects. Two hundred and four municipalities answered the questionnaire (69.1%); they were evaluated according to their respective population size., Conclusion: The availability of methodological procedures of studies that articulate epidemiological and evaluation methods allows generating more accurate and complete information and contribute with the design and evaluation of health policies, programs and actions.

Objective: To analyze association between presence of a companion during prenatal consultations and childbirth and quality of care received by puerperal women using the Brazilian National Health System (SUS)., Methods: This was a cross-sectional study with puerperal women who underwent prenatal care and delivery on the SUS in Santa Catarina State, Brazil, in 2019, and who were interviewed within 48 hours postpartum. Prevalence ratios were estimated using Poisson regression., Results: 3,580 puerperal women were interviewed. In prenatal care, presence of a companion was positively associated with receiving guidance from health professionals (PR=1.27 - 95%CI 1.08;1.50) and building a birth plan (PR=1.51 - 95%CI 1.15;1.97). At delivery, presence of a companion was associated with greater receipt of analgesics (PR=2.89 - 95%CI 1.40;5.97), non-pharmacological pain relief management (PR=1.96 - 95%CI 1.44;2.65), choice of position for delivery (PR=1.63 - 95%CI 1.24;2.16) and less likelihood of being strapped down (PR=0.47 - 95%CI 0.35;0.63)., Conclusion: Presence of a companion during prenatal care and delivery was associated with better quality of care.
