Difference of Socioeconomic Factors among Mothers of Preterm and Full-Term Infant

Abstract Objective: To analyze the difference of socioeconomic factors among mothers of preterm and full-term infants. Material and Methods: A cross-sectional retrospective study was developed with 250 mothers of children aged three to five years. The sample was divided into two groups: 125 mothers of preterm infants from the referral center of a public hospital in the city of Belo Horizonte, Brazil and 125 mothers of children born full-term at a daycare center within the same city. A pre-tested questionnaire was used to collect socioeconomic data and type of breastfeeding. To verify if there was association between the dependent variable gestational age at birth and the independent variables, the chi-square test was used. A final model with multiple Poisson regression estimated prevalence ratio values for each independent variable was developed. Results: The final multiple regression model showed that mothers that have a low monthly income of up to USD 450.28 (PR = 1.979, 95% CI = 1.082-3.620), used drugs, cigarettes, or alcohol during their pregnancy (PR = 4.095, 95% CI = 2.422-6.921), and did not breastfeed (PR = 2.294, 95% CI = 1.205-4.369) were more likely to give birth to preterm infants. Conclusion: Low monthly family income, use of drugs, alcohol, or smoking during pregnancy and absence of breastfeeding were more frequent on mothers of preterm infants.

Clinical application of the Newborn Behavioral Observation (NBO) System to characterize the behavioral pattern of newborns at biological and social risk / Aplicação clínica do Newborn Behavioral Observation (NBO) System para caracterizar o padrão comportamental dos recém-nascidos de risco biológico e social

Abstract Objective To compare the behavior of preterm newborns and full-term newborns using the Newborn Behavioral Observation and to evaluate the mothers' experience when participating in this observation. Method This was a cross-sectional study performed at a referral hospital for high-risk births, involving mothers and neonates before hospital discharge. The mothers answered the sociodemographic questionnaire, participated in the Newborn Behavioral Observation session, and evaluated the experience by answering the parents' questionnaire at the end. The characteristics of the preterm newborn and full-term newborn groups and the autonomic, motor, organization of states, and responsiveness scores were compared. Linear regression was performed to test the association of the characteristics of mothers and neonates with the scores in the autonomic, motor, organization of states, and responsiveness domains. Results The Newborn Behavioral Observation was performed with 170 newborns (eight twins and 77% preterm newborns). Approximately 15% of the mothers were adolescents and had nine years of schooling, on average. The groups differed regarding weight for gestational age, age at observation, APGAR score, feeding, and primiparity. The linear regression adjusted for these variables showed that only prematurity remained associated with differences in the scores of the motor (p = 0.002) and responsiveness (p = 0.02) domains. No statistical difference was observed between the groups in the score attributed to one's own knowledge prior to the session (p = 0.10). After the session, these means increased in both groups. This increase was significantly higher in the preterm newborn group (p = 0.02). Conclusions The Newborn Behavioral Observation increased the mothers' knowledge about the behavior of their children, especially in mothers of preterm newborns, and identified differences in the behavior of preterm newborns and full-term newborns regarding the motor and responsiveness domains.

Resumo Objetivo Comparar o comportamento de recém-nascidos pré-termo e a termo utilizando a Newborn Behavioral Observation e avaliar a experiência das mães em participar dessa observação. Método Estudo transversal realizado em hospital de referência para partos de risco, envolvendo mães e neonatos antes da alta hospitalar. As mães responderam ao questionário sociodemográfico, participaram da sessão de Newborn Behavioral Observation e ao final avaliaram a experiência e responderam ao questionário de pais. As características dos grupos de recém-nascidos pré-termo e recém-nascidos termo e os escores dos domínios autonômico, motor, organização dos estados e responsividade foram comparados. Realizou-se regressão linear para testar a associação de características das mães e neonatos com os escores nos domínios autonômico, motor, organização dos estados e responsividade. Resultados A Newborn Behavioral Observation foi realizada com 170 recém-nascidos (oito gemelares e 77% pré-termo). Cerca de 15% das mães eram adolescentes e estudaram em média por 9 anos. Os grupos diferiram quanto ao peso para idade gestacional, idade na observação, APGAR, alimentação e primiparidade. A regressão linear ajustada para essas variáveis mostrou que apenas a prematuridade manteve-se associada a diferenças nos escores dos domínios motor (p = 0,002) e responsividade (p = 0,02). Não houve diferença estatística entre os grupos na pontuação atribuída ao próprio conhecimento antes da sessão (p = 0,10). Após a sessão estas médias subiram em ambos os grupos. Esse aumento foi significativamente maior no grupo de recém-nascidos pré-termo (p = 0,02). Conclusões A Newborn Behavioral Observation aumentou o conhecimento das mães sobre o comportamento dos filhos, principalmente para as mães de recém-nascidos pré-termo, e identificou diferenças no comportamento de recém-nascidos pré-termo e recém-nascidos termo nos domínios motor e responsividade.
