Factors associated with people's behavior in social isolation during the COVID-19 pandemic

This paper presents the results of an opinion poll conducted in Brazil on the perception of social isolation during the COVID-19 pandemic. The questionnaire was prepared on Google Forms, disseminated through social networks, with questions about the socioeconomic profile and factors associated with isolation. A non-probabilistic sample was obtained with 16,440 respondents. Data were analyzed using the Stata 13 software. Social interaction was the most affected aspect among people with higher education and income (45.8%), and financial problems caused a more significant impact (35%) among people with low income and education. Those who practice some physical activity showed lower levels of stress 13%, as well as greater normality in sleep 50.3%. People who reported living in worse habitability conditions reported willingness to remain isolated for less time, 73.9%. Among non-isolated people (10.7% of the total sample), 75.8% believe that social isolation will reduce the number of victims of COVID-19. We conclude, based on this sample, that the perception about social isolation as a pandemic mitigation action varies by income, education, age, and gender. However, most believe that it is the most appropriate control measure and are willing to wait as long as necessary to contribute to the fight against COVID-19.

Geography of Microcephaly in the Zika Era: A Study of Newborn Distribution and Socio-environmental Indicators in Recife, Brazil, 2015-2016

OBJECTIVES

We assessed sociodemographic and health care factors of mothers and newborns during a 2015-2016 outbreak of microcephaly in Recife, Brazil, and we analyzed the spatial distribution and incidence risk of newborns with microcephaly in relation to socio-environmental indicators.

METHODS

We collected data from August 2015 through May 2016 from Brazil's Live Birth Information System and Bulletin of Microcephaly Notification, and we geocoded the data by maternal residence. We constructed thematic maps of districts, according to socio-environmental and vector indicators. We identified spatial aggregates of newborns with microcephaly by using the Bernoulli model. We performed logistic regression analyses to compare the incidence risk of microcephaly within socio-environmental indicator groups.

RESULTS

We geocoded 17 990 of 19 554 (92.0%) live births in Recife, of which 202 (1.1%) newborns were classified as having microcephaly, based on a head circumference of ≥2 standard deviations below the mean. Larger proportions of newborns with microcephaly (compared with newborns without microcephaly) were born to mothers who delivered in a public hospital, did not attend college, were aged ≤19, or were black or mixed race. A higher risk of microcephaly (incidence rate ratio [IRR] = 3.90; 95% confidence interval [CI], 1.88-8.06) occurred in districts with the lowest (vs highest) Municipal Human Development Index (ie, an index that assesses longevity, education, and income). The risk of microcephaly was significantly higher where rates of larvae density (IRR = 2.31; 95% CI, 1.19-4.50) and larvae detection (IRR = 2.04; 95% CI, 1.05-4.00) were higher and rates of sewage system (IRR = 2.20; 95% CI, 1.16-4.18) and garbage collection (IRR = 1.96; 95% CI, 0.99-3.88) were lower. Newborns with microcephaly lived predominantly in the poorest areas and in a high-risk cluster (relative risk = 1.89, P = .01) in the north.

CONCLUSIONS

The disproportionate incidence of microcephaly in newborns in poor areas of Recife reinforces the need for government and public health authorities to formulate policies that promote social equity and support for families and their children with microcephaly.

Vigilância em saúde ambiental no Brasil: heranças e desafios

Resumo Este artigo apresenta alguns pontos do debate sobre o campo da saúde ambiental, em especial sobre o surgimento da vigilância em saúde ambiental no âmbito das políticas públicas do Sistema Único de Saúde (SUS). Para sua construção, realizou-se uma revisão teórica e uma análise de alguns instrumentos normativos que regulam essa área de vigilância. O texto está estruturado em quatro partes: num primeiro momento, destacaremos a importância da compreensão da saúde ambiental como um campo interdisciplinar; o segundo tópico corresponde a um breve histórico das relações entre saúde e ambiente; na terceira seção destacamos a discussão sobre as categorias de promoção e vigilância à saúde, quando discutiremos suas heranças e desafios; por fim, debatemos a questão da vigilância em saúde ambiental, apresentando sua organização enquanto parte integrante do SUS, seus marcos teóricos e institucionais. Concluímos que a área da vigilância em saúde ambiental no Brasil apresenta alguns importantes avanços e está em processo de amadurecimento, haja vista as constantes modificações na sua estrutura regulatória, mas também consideramos lenta a incorporação das questões ambientais no campo das políticas públicas de saúde.

Participatory methodology as an instrument for the territorialization of Environmental Surveillance actions

This paper aims to show a health territorialization methodology built from the experiences of endemic control and environmental health agents in the Metropolitan Region of Recife (RMR). Ten workshops were held with the participation of three hundred Health Surveillance agents and supervisors working in four municipalities of the RMR. Techniques such as the application of questionnaires, interviews and directed discussions were used. Results indicate that the incorporation of geographical concepts to consolidate Health Surveillance field actions is incipient. The territory is predominantly adopted from an administrative perspective, and territorialization is used as a simple territorial division for the development of actions. However, there is an understanding and consensus of the need to understand the geographic knowledge, a fact that was expressed by the rich collective construction of a participatory territorialization model that should involve a range of social stakeholders. We concluded that, in practice, surveillance agents have significant abilities to participate in the territorial management and territorialization process, not only collecting data, but also mainly intervening for the collective well-being.
