Mother,infant behavioral interactions in teenage and adult mothers during the first six months postpartum: Relations with infant development

INFANT MENTAL HEALTH JOURNAL, Issue 5 2003
Andrée Pomerleau
The purpose of this study was to compare adolescent mothers' (high-risk group), at-risk adult mothers' (moderate-risk group), and no-risk adult mothers' (low-risk group) behavioral interactions at one and six months postpartum, and to examine the relationships between maternal behaviors and infant developmental scores on the Bayley scales. Results indicated that high-risk teenage mothers and moderate-risk adult mothers vocalized less and had lower contingency rating scores compared to low-risk adult mothers. Also, infants in the high-risk and moderate-risk groups obtained lower mental scores at six months compared to the low-risk group. Moderate stability across time was found for maternal vocalizations and infant scores on the mental scale. Maternal vocalizations and behavioral contingency rating scores at one month were associated with infants' six-month performance on the Bayley scales. Specific intervention strategies were discussed with the aim of targeting and improving early maternal behavioral patterns in at-risk groups. ©2003 Michigan Association for Infant Mental Health.

Functionalized 3,3,,5,5,-Tetraaryl-1,1,-Biphenyls: Novel Platforms for Molecular Receptors

HELVETICA CHIMICA ACTA, Issue 3 2003
Roger Welti
This paper describes the development of novel aromatic platforms for supramolecular construction. By the Suzuki cross-coupling protocol, a variety of functionalized m- terphenyl derivatives were prepared (Schemes,1,4). Macrolactamization of bis(ammonium salt) (S,S)- 6 with bis(acyl halide) 7 afforded the macrocyclic receptor (S,S)- 2 (Scheme,1), which was shown by 1H-NMR titration studies to form ,nesting' complexes of moderate stability (Ka between 130 and 290,M,1, 300,K) with octyl glucosides 13,15 (Fig.,2) in the noncompetitive solvent CDCl3. Suzuki cross-coupling starting from 3,3,,5,5,-tetrabromo-1,1,-biphenyl provided access to a novel series of extended aromatic platforms (Scheme,5) for cleft-type (Fig.,1) and macrotricyclic receptors such as (S,S,S,S)- 1. Although mass-spectral evidence for the formation of (S,S,S,S)- 1 by macrolactamization between the two functionalized 3,3,,5,5,-tetraaryl-1,1,-biphenyl derivatives (S,S)- 33 and 36 was obtained, the 1H- and 13C-NMR spectra of purified material remained rather inconclusive with respect to both purity and constitution. The versatile access to the novel, differentially functionalized 3,3,,5,5,-tetrabromo-1,1,-biphenyl platforms should ensure their wide use in future supramolecular construction. [source]

The influence of infant irritability on maternal sensitivity in a sample of very premature infants

INFANT AND CHILD DEVELOPMENT, Issue 2 2003
Petra Meier
Abstract The relationship between maternal sensitivity and infant irritability was investigated in a short-term longitudinal study of 29 very preterm infants. Infant irritability was assessed at term with the Brazelton NBAS, the Mother and Baby Scales (MABS) and the Crying Pattern Questionnaire (CPQ). Maternal sensitivity was assessed by nurses' ratings in the neonatal care unit and at three months during mother,infant interaction observation. Cross-lagged panel analysis indicated that neonatal irritability did not influence sensitivity at 3 months nor did maternal sensitivity in the newborn period lead to reduced irritability at 3 months. Both irritability and maternal sensitivity showed moderate stability over time (r = 0.55 and r = 0.60, respectively). It is concluded that in early infancy maternal sensitivity shows little influence on infant irritability in very preterm infants. Copyright © 2003 John Wiley & Sons, Ltd. [source]

A Latent Growth Curve Analysis of Prosocial Behavior Among Rural Adolescents

JOURNAL OF RESEARCH ON ADOLESCENCE, Issue 2 2007
Gustavo Carlo
The present study was designed to investigate stability and changes in prosocial behavior and the parent and peer correlates of prosocial behavior in rural adolescents. Participants were from a rural, low SES community in the Eastern United States. The participants were in 7th, 8th, and 9th grades at Time 1 and 10th, 11th, and 12th grades at Time 4, and completed measures of prosocial behavior and quality of parent and peer relationships. Latent growth curve modeling revealed that despite moderate stability in individual differences in prosocial behavior and slight increases in quality of peer and parent relationships, level of prosocial behavior declined until late high school with a slight rebound in grade 12. Furthermore, increases in the quality of peer relationships predicted decreases in prosocial behavior for girls but not boys. Discussion focuses on continuity and change in prosocial behavior and the gender-based relations between quality of parent and peer relationships and prosocial behaviors in adolescence. [source]

Emotion Dialogues Between Mothers and Children at 4.5 and 7.5 Years: Relations With Children's Attachment at 1 Year

CHILD DEVELOPMENT, Issue 1 2007
David Oppenheim
It was examined whether secure infant,mother attachment contributes to emotionally congruent and organized mother,child dialogues about emotions in later years. The attachment of 99 children was assessed using the Strange Situation at the age of 1 year and their emotion dialogues with their mothers were assessed at the ages of 4.5 and 7.5 years. Dialogues were about past emotional events and separation of a child from parents, and were classified into an emotionally matched group or 1 of 3 non-emotionally matched groups. Security in infancy was associated with emotionally matched dialogues at the age of 4.5; there was moderate stability in dialogues between 4.5 and 7.5 years; and infant attachment predicted dialogues at 7.5 beyond the prediction offered by age 4.5 dialogues.

Lack of association between television viewing, soft drinks, physical activity and body mass index in children

ACTA PAEDIATRICA, Issue 6 2008
Kelly Laurson
Abstract Objective: To examine the cross-sectional and longitudinal associations of physical activity, screen time and dietary habits on the body mass index (BMI) of children. Methods: A cohort of 122 girls and 146 boys (age at entry 10 years) from three rural states in the western USA was studied over an 18-month period. Subjects were measured for height and weight. Habitual physical activity, screen time (television viewing, video games and computer use) and dietary variables were assessed by a questionnaire. Cross-sectional and longitudinal analyses were conducted to examine the associations between physical activity, screen time and diet with BMI at baseline and follow-up and change in BMI. Results: At baseline, approximately 10% of boys and girls were obese and 17.8% of boys and 14.8% of girls were overweight. BMI showed a high degree of stability for boys and girls (r = 0.90), whereas physical activity, screen time and dietary habits showed moderate stability (r = 0.31,0.50) across the 18-month period. Cross-sectional and longitudinal correlations between physical activity, screen time, diet and BMI were low and non-significant (r < 0.15). The regression models explained between 8% and 22% of the variance in the change in BMI; however, none of the predictor variables were statistically significant. Conclusion: Physical activity, screen time and dietary habits were not significantly related to the BMI in cross-sectional or longitudinal analyses. Further research is warranted to better understand the complex, multifactorial phenotype of the BMI in growing and maturing children. [source]
