Partners with a Highly Favorable Attitude Toward Breastfeeding Contribute to Promoting Initiation and Length of Breastfeeding for More than 5 Months in a Population-Based Canadian Study

Introduction: Promoting maternal breastfeeding for at least 6 months is important to improve children physical health during infancy and neurodevelopmental outcomes in childhood. For this guideline to be followed, it is paramount to identify what factors best support the initiation and length of breastfeeding. This study estimates the contribution of various child- and parent-level factors, as well as the sociodemographic context in predicting maternal breastfeeding initiation and duration. Methods: This study draws on data from the Quebec Longitudinal Study of Child Development. Mothers who never breastfed when the infant was 5 months old (n = 630, 28.3%) were compared to mothers who breastfed for less than 5 months (n = 844, 38.0%) and mothers breastfeeding for more than 5 months (n = 749, 33.7%), using multivariable multinomial regression models. Results: Mothers with a partner showing a positive attitude toward breastfeeding were up to 13 times more likely to breastfeed their infant for more than 5 months. The positive attitude of partners toward breastfeeding was the strongest predictor of breastfeeding duration, followed by the maternal educational attainment and timing she returns to work. Most prenatal and perinatal child-level factors and the sociodemographic context predicted breastfeeding duration, but to a lesser extent. Discussion: This finding underscores the role of the partner's attitude in promoting initiation and length of breastfeeding. As such, educational campaigns and health practitioners could target both the mother and their partner in promoting breastfeeding.

Unraveling the effects of maternal breastfeeding duration and exclusive breast milk on children's cognitive abilities in early childhood

Background

This study investigated the putative associations between mothers' use of exclusive breast milk and the duration of breastfeeding with child cognitive development.

Methods

This study is based on 2,210 Canadian families with children assessed longitudinally from age 4 to 7 years on their memory-span and math skills. These cognitive abilities were measured with standardized tasks. Breastfeeding practices were collected via maternal reports. We applied propensity scores to control the social selection bias for breastfeeding.

Results

Results adjusted for propensity scores and sample weight revealed no significant differences between non-breastfed children with those being non-exclusively breastfed for 5 months or less, and with children being exclusively breastfed for 9.2 months on average, on their early math skills and memory-span. We found that children who were non-exclusively breastfed for 6.8 months on average had a slightly higher levels of memory-span at age 4 than children who were never breastfed, and this small but significant difference lasted up to age 7.

Conclusion

Our findings suggest no significant differences between children being exclusively breastfed and those fed with formula on their early math skills and memory-span. The encouragement of breastfeeding to promote child cognitive school readiness may, in some case (non-exclusive breastfeeding for more than 5 months), show a small but long-lasting advantage in early memory-span.

Associations Between Video Game Engagement and ADHD Symptoms in Early Adolescence

OBJECTIVE

We aim to investigate the direction of causality of the association between adolescent video game playing and later development of ADHD symptoms using a population-based sample of Canadian Youth.

METHOD

The present study is based on longitudinal cohort data (N = 1,467). Youth self-reported weekly hours of video game playing as well as ADHD symptoms at both 12 and 13 years of age.

RESULTS

Cross-lagged panel model were estimated to examine how adolescent video game playing prospectively contributes to ADHD symptoms while simultaneously considering how adolescent ADHD symptoms may prospectively contribute to videogame playing. Analyses revealed a significant positive association between adolescent video games playing at age 12 and ADHD symptoms at age 13. Youth ADHD symptoms at age 12 did not predict video game use at age 13.

CONCLUSION

Our results help clarify the direction of causality of the association between video game playing and ADHD symptoms and provide evidence that video game playing can represent a risk factor for the development of attention problems in early adolescence.

Vivências Acadêmicas e Sofrimento Psíquico de Estudantes de Psicologia

Resumo A vivência estudantil na universidade é uma questão pouco investigada e discutida, especialmente nos cursos de Psicologia, assim como o sofrimento que pode acompanhá-la, decorrente sobretudo do contato com o sofrimento psíquico de outras pessoas ou os conteúdos acadêmicos mais diretamente relacionados com a subjetividade humana. Este artigo apresenta dados de uma pesquisa cujo objetivo era o levantamento das vivências acadêmicas dos estudantes de Psicologia de uma universidade pública do interior paulista. Na coleta de dados foi utilizado um instrumento, contendo uma questão de identificação sociodemográfica, um conjunto de 20 itens de múltipla escolha (formulado como numa escala do tipo likert de cinco pontos) e cinco questões abertas, que foi respondido por 119 estudantes dos cinco anos do curso. Os resultados, após serem submetidos às análises quantitativa e qualitativa, permitiram verificar que, na Escala Likert, os alunos apresentaram, no geral, percepção favorável do curso. No entanto, nas questões abertas referentes às vivências e ao sofrimento psíquico foram apresentados indicadores explícitos de mal-estar universitário. Na última questão, que indagava sobre a vivência de sofrimento psíquico, 107 dos 119 estudantes responderam afirmativamente. A partir destes dados, se discute a necessidade urgente de ações, tanto por parte dos gestores universitários quanto das entidades que fiscalizam a formação de psicólogos.
