O impacto doenvolvimento paterno e dos estilos parentais nas relações de coparentalidade?: um olhar sobre a parentalidade

Profundas mudanças socioculturais, como o aumento da participação da mulher no mercado de trabalho, desencadearam alterações nas expectativas relativas aos papéis de género, bem como uma reorganização da vida familiar, implicando na forma como a parentalidade é exercida. Surge um novo ideal de partilha parental e o papel do pai redefine-se, esperando-se um cuidador mais afetuoso e participativo no quotidiano dos filhos, assumindo especial importância, não apenas o tempo que este despende na interação com os filhos, mas também a qualidade desta relação. Assim, o objetivo do presente estudo visa analisar a perceção que mães e pais têm sobre a qualidade da relação coparental, tendo sido controladas algumas variáveis sociodemográficas, e a relação daquela com o envolvimento paterno e com os estilos parentais de mãe e pai. A amostra constituiu-se por 64 mães e 44 pais, de famílias nucleares portuguesas, com crianças em idade pré-escolar. As figuras parentais responderam a um questionário sociodemográfico (mãe), à Escala da Relação Coparental (mãe e pai); à Escala de Envolvimento Parental: Participação em Atividades de Cuidados e de Socialização (pai) e ao Questionário de Estilos e Dimensões Parentais (mãe e pai). Os resultados indicaram que ambos os pais reportam uma perceção que corresponde a maior qualidade da relação coparental. Verificou-se que o envolvimento do pai, ao nível dos Cuidados e da Socialização, e os estilos parentais de mãe e pai, se encontram associados à qualidade da relação coparental. Dado o seu reduzido número, estudos que analisem a relação entre as referidas variáveis, tornam-se necessários.Profound socio-cultural changes, such as increasing women's participation in the labour market, triggered changed in expectations regarding gender roles, as well as reorganization of family life, implying the way parenthood is exercised. A new ideal of parental sharing emerges and the role of the father is relocated, expecting a more affectionate and participative caregiver in the daily life of the children, assuming special importance, not only the time spent in the interaction with the children, but also the quality of this relationship. Thus, the objective of the present study is to analyse the perception that mothers and fathers have about the quality of the coparental relationship, having been controlled some sociodemographic variables, and the relationship with the parental involvement and parental styles of mother and father. The sample consisted of 64 mothers and 44 parents, of Portuguese nuclear families with children of preschool age. The parental figures answered a socio-demographic questionnaire (mother), the Coparental Relationship Scale (mother and father); and the Parental Involvement Scale; Participation in Care and Socialization Activities (father), and the Parenting Styles and Dimensions Questionnaire (mother and father). The results indicated that both parents report a perception that corresponds to the highest quality of the coparenting relationship. It was verified that the father's involvement, at the level of care and socialization and parental styles of mother and father, are associated with the quality of the coparental relationship. Given its small number, studies that analyse the relationship between these variables become necessary

Importance attributed by adolescents to sexual education: correlation with their attitudes, knowledge, and sexual behavior

Introduction: Sexual education plays an important role in the prevention of risk-taking sexual behaviors. The objective of this study was to evaluate the importance attributed to sexual education by adolescents, correlating it with the assessment they make of their attitudes and with their knowledge towards sexuality. Methods: This observational study included adolescents who attended elementary or high school in the central region of Portugal. A characterization of sociodemographic and sexual data was made and the Adolescent Students’ Attitudes Scale towards Sexuality (E3AS) was applied. Results: We included 394 adolescents with a mean age of 14.9 ± 1.4 years. The majority (89.3%) attributed importance to sexual education. Adolescents that gave more importance to sexual education were the ones that ranked higher the information they learned about sexuality (r = 0.236), had less unprotected sex due to lack of information (r = -0.363) or because they were under the effect of alcohol and/or drugs (r = -0.365) and had a superior classification in F2 (r = 0.380), F5 (r = 0.402) and in the total scale (r = 0.531). Discussion and conclusion: Adolescents that attributed greater importance to sexual education were the ones that ranked higher the information they possessed about sexuality. After initiating sexual activity, a greater importance attributed to sexual education seems to have a protective effect on risk-taking sexual behaviors.Introdução: A educação sexual desempenha um papel importante na prevenção de comportamentos sexuais de risco. O objetivo deste estudo foi avaliar a importância atribuída à educação sexual por adolescentes, correlacionando-a com a avaliação que eles fazem de suas atitudes e com seus conhecimentos em relação à sexualidade. Métodos: Este estudo observacional incluiu adolescentes que cursaram o ensino fundamental ou médio na região central de Portugal. Foi feita uma caracterização dos dados sociodemográficos e sexuais e foi aplicada a Escala de Atitudes dos Adolescentes em relação à Sexualidade (E3AS). Resultados: Foram incluídos 394 adolescentes com idade média de 14,9 ± 1,4 anos. A maioria (89,3%) atribuiu importância à educação sexual. Os adolescentes que deram mais importância à educação sexual foram os que obtiveram maior classificação nas informações sobre sexualidade (r = 0,236), tiveram sexo menos desprotegido por falta de informação (r = -0,363) ou porque estavam sob efeito de álcool e/ou drogas (r = -0,365) e tiveram uma classificação superior em F2 (r = 0,380), F5 (r = 0,402) e na escala total (r = 0,531). Discussão e conclusão: Os adolescentes que atribuíam maior importância à educação sexual eram os que melhor classificavam as informações que possuíam sobre a sexualidade. Após iniciar a atividade sexual, uma maior importância atribuída à educação sexual parece ter um efeito protetor sobre os comportamentos sexuais de risco.info:eu-repo/semantics/publishedVersio

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Height and body-mass index trajectories of school-aged children and adolescents from 1985 to 2019 in 200 countries and territories: a pooled analysis of 2181 population-based studies with 65 million participants

Summary Background Comparable global data on health and nutrition of school-aged children and adolescents are scarce. We aimed to estimate age trajectories and time trends in mean height and mean body-mass index (BMI), which measures weight gain beyond what is expected from height gain, for school-aged children and adolescents. Methods For this pooled analysis, we used a database of cardiometabolic risk factors collated by the Non-Communicable Disease Risk Factor Collaboration. We applied a Bayesian hierarchical model to estimate trends from 1985 to 2019 in mean height and mean BMI in 1-year age groups for ages 5–19 years. The model allowed for non-linear changes over time in mean height and mean BMI and for non-linear changes with age of children and adolescents, including periods of rapid growth during adolescence. Findings We pooled data from 2181 population-based studies, with measurements of height and weight in 65 million participants in 200 countries and territories. In 2019, we estimated a difference of 20 cm or higher in mean height of 19-year-old adolescents between countries with the tallest populations (the Netherlands, Montenegro, Estonia, and Bosnia and Herzegovina for boys; and the Netherlands, Montenegro, Denmark, and Iceland for girls) and those with the shortest populations (Timor-Leste, Laos, Solomon Islands, and Papua New Guinea for boys; and Guatemala, Bangladesh, Nepal, and Timor-Leste for girls). In the same year, the difference between the highest mean BMI (in Pacific island countries, Kuwait, Bahrain, The Bahamas, Chile, the USA, and New Zealand for both boys and girls and in South Africa for girls) and lowest mean BMI (in India, Bangladesh, Timor-Leste, Ethiopia, and Chad for boys and girls; and in Japan and Romania for girls) was approximately 9–10 kg/m2. In some countries, children aged 5 years started with healthier height or BMI than the global median and, in some cases, as healthy as the best performing countries, but they became progressively less healthy compared with their comparators as they grew older by not growing as tall (eg, boys in Austria and Barbados, and girls in Belgium and Puerto Rico) or gaining too much weight for their height (eg, girls and boys in Kuwait, Bahrain, Fiji, Jamaica, and Mexico; and girls in South Africa and New Zealand). In other countries, growing children overtook the height of their comparators (eg, Latvia, Czech Republic, Morocco, and Iran) or curbed their weight gain (eg, Italy, France, and Croatia) in late childhood and adolescence. When changes in both height and BMI were considered, girls in South Korea, Vietnam, Saudi Arabia, Turkey, and some central Asian countries (eg, Armenia and Azerbaijan), and boys in central and western Europe (eg, Portugal, Denmark, Poland, and Montenegro) had the healthiest changes in anthropometric status over the past 3·5 decades because, compared with children and adolescents in other countries, they had a much larger gain in height than they did in BMI. The unhealthiest changes—gaining too little height, too much weight for their height compared with children in other countries, or both—occurred in many countries in sub-Saharan Africa, New Zealand, and the USA for boys and girls; in Malaysia and some Pacific island nations for boys; and in Mexico for girls. Interpretation The height and BMI trajectories over age and time of school-aged children and adolescents are highly variable across countries, which indicates heterogeneous nutritional quality and lifelong health advantages and risks

Worldwide trends in underweight and obesity from 1990 to 2022: a pooled analysis of 3663 population-representative studies with 222 million children, adolescents, and adults

Background Underweight and obesity are associated with adverse health outcomes throughout the life course. We estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from 1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories. Methods We used data from 3663 population-based studies with 222 million participants that measured height and weight in representative samples of the general population. We used a Bayesian hierarchical model to estimate trends in the prevalence of different BMI categories, separately for adults (age ≥20 years) and school-aged children and adolescents (age 5–19 years), from 1990 to 2022 for 200 countries and territories. For adults, we report the individual and combined prevalence of underweight (BMI <18·5 kg/m2) and obesity (BMI ≥30 kg/m2). For schoolaged children and adolescents, we report thinness (BMI <2 SD below the median of the WHO growth reference) and obesity (BMI >2 SD above the median). Findings From 1990 to 2022, the combined prevalence of underweight and obesity in adults decreased in 11 countries (6%) for women and 17 (9%) for men with a posterior probability of at least 0·80 that the observed changes were true decreases. The combined prevalence increased in 162 countries (81%) for women and 140 countries (70%) for men with a posterior probability of at least 0·80. In 2022, the combined prevalence of underweight and obesity was highest in island nations in the Caribbean and Polynesia and Micronesia, and countries in the Middle East and north Africa. Obesity prevalence was higher than underweight with posterior probability of at least 0·80 in 177 countries (89%) for women and 145 (73%) for men in 2022, whereas the converse was true in 16 countries (8%) for women, and 39 (20%) for men. From 1990 to 2022, the combined prevalence of thinness and obesity decreased among girls in five countries (3%) and among boys in 15 countries (8%) with a posterior probability of at least 0·80, and increased among girls in 140 countries (70%) and boys in 137 countries (69%) with a posterior probability of at least 0·80. The countries with highest combined prevalence of thinness and obesity in school-aged children and adolescents in 2022 were in Polynesia and Micronesia and the Caribbean for both sexes, and Chile and Qatar for boys. Combined prevalence was also high in some countries in south Asia, such as India and Pakistan, where thinness remained prevalent despite having declined. In 2022, obesity in school-aged children and adolescents was more prevalent than thinness with a posterior probability of at least 0·80 among girls in 133 countries (67%) and boys in 125 countries (63%), whereas the converse was true in 35 countries (18%) and 42 countries (21%), respectively. In almost all countries for both adults and school-aged children and adolescents, the increases in double burden were driven by increases in obesity, and decreases in double burden by declining underweight or thinness. Interpretation The combined burden of underweight and obesity has increased in most countries, driven by an increase in obesity, while underweight and thinness remain prevalent in south Asia and parts of Africa. A healthy nutrition transition that enhances access to nutritious foods is needed to address the remaining burden of underweight while curbing and reversing the increase in obesit

Multidifferential study of identified charged hadron distributions in ZZ-tagged jets in proton-proton collisions at s=\sqrt{s}=13 TeV

Jet fragmentation functions are measured for the first time in proton-proton collisions for charged pions, kaons, and protons within jets recoiling against a $Z$ boson. The charged-hadron distributions are studied longitudinally and transversely to the jet direction for jets with transverse momentum 20 $< p_{\textrm{T}} < 100$ GeV and in the pseudorapidity range $2.5 < \eta < 4$. The data sample was collected with the LHCb experiment at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 1.64 fb$^{-1}$. Triple differential distributions as a function of the hadron longitudinal momentum fraction, hadron transverse momentum, and jet transverse momentum are also measured for the first time. This helps constrain transverse-momentum-dependent fragmentation functions. Differences in the shapes and magnitudes of the measured distributions for the different hadron species provide insights into the hadronization process for jets predominantly initiated by light quarks.Comment: All figures and tables, along with machine-readable versions and any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-013.html (LHCb public pages
