Prenatal air pollution exposure and growth and cardio-metabolic risk in preschoolers

2020

Objectives: We investigated the association between outdoor air pollutants exposure in the first trimester of pregnancy, and growth and cardio-metabolic risk at four years of age, and evaluated the mediating role of birth weight. Methods: We included mother-child pairs (N = 1,724) from the Spanish INMA birth cohort established in 2003-2008. First trimester of pregnancy nitrogen dioxide (NO2) and fine particles (PM2.5) exposure levels were estimated. Height, weight, waist circumference, blood pressure, and lipids were measured at four years of age. Body mass index (BMI) trajectories from birth to four years were identified. Results: Increased PM2.5 exposure in the first trimester of pregnanc…

A person-oriented approach to maternal homework involvement during the transition to lower secondary school

2022

This study examined patterns of mothers' homework involvement (n = 680 in Grade 6 and 665 in Grade 7) and changes in them during 12-year-old Finnish adolescents' (n = 848; 391 boys) transition to lower secondary school. Moreover, the extent to which adolescents' motivational behavior and prior academic achievement predicted these patterns was examined. The latent transition analyses identified four relatively stable latent patterns of maternal homework involvement in Grades 6 and 7: averagely involved, psychologically controlling and intrusive, noninvolved, and intrusive monitoring and helping. The higher task avoidance and the poorer achievement adolescents showed, the more likely their mo…

The interplay between maternal homework involvement, task-avoidance, and achievement among adolescents.

2021

This study examined three aspects of maternal homework involvement (i.e., the quantity, quality, and source of initiative) and their direct and indirect associations with adolescents’ task-avoidant behavior in homework situations and academic achievement. The sample consisted of Finnish mothers and their adolescents who were transitioning from primary to lower secondary school. Mothers rated the quantity of their homework involvement (i.e., monitoring and help), quality of their homework involvement (i.e., autonomy support and psychological control), and source of initiative (i.e., mother- vs. adolescent-initiated monitoring and help) at the beginning of Grade 6. They also reported on adole…

The parental bond, resistance to peer influence and risky driving in adolescence

2014

The present study examined the relations between gender, the parental bond, resistance to peer influence, and risky driving. In particular, the mediating role of resistance to peer pressure in the relationship between parental bond and risky driving was examined. The moderating role of gender on these associations was also investigated. The sample comprised 322 adolescents (136 males and 186 females), aged from 16 to 20 years, who were living in northern Italy. Path analysis results showed that the maternal bond only indirectly influenced adolescents’ risky driving, via resistance to peer influence. On the contrary, the paternal bond was neither directly nor indirectly associated with risky…

Parenting e culture a confronto. Un’indagine esplorativa*

The relationship between maternal-fetus attachment and perceived parental bonds in pregnant women: Considering a possible mediating role of psycholog…

2023

Maternal-Fetal Attachment (MFA) delineates the emotional, cognitive, and behavioral aspects that mothers develop toward the unborn baby during pregnancy. The literature indicates that optimal attachment in pregnancy represents a protective factor for the mother-child attachment bond after birth and child development outcomes. To date, there are few studies that have investigated associated factors of MFA. This study sets out to explore the association between perceived parental bonds and maternal-fetal bonding in pregnant women, accounting for factors such as psychological distress, socio-demographic and obstetric characteristics.MethodsIn this cross-sectional study, 1,177 pregnant women an…

Maternally‐transferred thyroid hormones and life‐history variation in birds

2022

1. In vertebrates, thyroid hormones (THs) play an important role in the regulation of growth, development, metabolism, photoperiodic responses and migration. Maternally transferred THs are important for normal early-phase embryonic development when embryos are not able to produce endogenous THs. Previous studies have shown that variation in maternal THs within the physiological range can influence offspring phenotype. 2. Given the essential functions of maternal THs in development and metabolism, THs may be a mediator of life-history variation across species. 3. We tested the hypothesis that differences in life histories are associated with differences in maternal TH transfer across species…

I luoghi della nascita: una ricerca-intervento sui fattori di rischio nelle madri migranti

2010

Pregnancy involves physical changes but also relational and affective ones. During the nine months’ period and in the months following the birth, women develop a series of expectations and fantasies about themselves and their child. The way women live their motherhood expresses, in addition, the cultural values, the myths, the rules society has transmitted to them. Then, birth can be considered as a cultural event with distinctive features. Moving from these considerations, we wondered how immigrant women live their experience of motherhood in a foreign country. We examined the way women reconstruct the history of their pregnancy in relation to their own maternal identity, the identity of t…

Efecto de la dosis de intervención del Programa de Apoyo Psicológico P/Materno Infantil© sobre las madres y sus bebés

2014

This paper presents an analysis of the intervention dose-effect of the Parent Child Psychological Support Program© (Cerezo 1990) a program aimed at promoting protective adaptive system in children which is offered to all new-borns in a given catchment area. The program offers support to parents during the first 18 months of the baby's life. The program dose-effect is examined regarding the parents by examining the level of distress reported by them and with babies by examining the development of attachment using the Strange Situation test of Ainsworth et al. (1978). The study is based on 342 families who made between 2 and 4 visits to the Program before being evaluation post-intervention. T…

Motherhood‐induced gene expression in the mouse medial amygdala: Changes induced by pregnancy and lactation but not by pup stimuli

2021

During lactation, adult female mice display aggressive responses toward male intrud-ers, triggered by male- derived chemosensory signals. This aggressive behavior is not shown by pup- sensitized virgin females sharing pup care with dams. The genetic mechanisms underlying the switch from attraction to aggression are unknown. In this work, we investigate the differential gene expression in lactating females ex-pressing maternal aggression compared to pup- sensitized virgin females in the me-dial amygdala (Me), a key neural structure integrating chemosensory and hormonal information. The results showed 197 genes upregulated in dams, including genes encoding hormones such as prolactin, growth h…
