Objective. Smoking has a detrimental impact on maternal physical health and exposes children to secondhand smoke, but the extent to which it affects maternal brain and behavior is not well-known and may have implications for parent and child development. We examined how current smoking status might relate to maternal neural responses to infant cues using event-related potentials. Design. Current smoking (n = 35) and non-smoking (n = 35) mothers viewed photographs of emotional infant faces while electroencephalography was simultaneously recorded. Results. The latency of the face-specific N170 event-related potential component was delayed in smoking mothers compared to non-smoking mothers, and the P300 was differentiated by smoking status. Conclusions. Postpartum smoking is associated with event-related potential measures that may reflect modulation of infant face perception in motherhood.  相似文献

In this study, the impact of rejection/acceptance experienced during the adolescent mother's childhood, social support received after the baby's birth, and infant irritability on angry, punitive maternal behavior are tested, and possible links between such maternal behavior and indices of child anger and noncompliance, low confidence, and social withdrawal are investigated. 40 mothers who gave birth as adolescents and their 2-year-old children participated in the study. When mothers experienced both rejection during childhood and little support from a partner after birth, they were likely to exhibit angry and punitive parenting. Infant irritability did not predict maternal behavior. Angry and punitive mothers had children who were angry and noncompliant and who distanced themselves from their mothers. Taken as a main effect, infant irritability was unrelated to later child behavior. However, the association between maternal behavior and 2 aspects of child behavior was stronger for children as irritable at 3 months postpartum: when irritable infants had angry and punitive mothers they were more likely to be angry and noncompliant and to exhibit less confidence than less irritable infants who experienced the same pattern of parenting.  相似文献

The aim of this study was to assess the association between the length of maternity leave and the quality of mother-infant interactions; 198 employed mothers of 4-month-old infants were interviewed and videotaped in their homes during a feeding time. Hierarchical multiple regression analyses indicated a direct association between shorter length of leave and more negative affect and behavior in maternal interactions with their infants. Infant and mother stressor/protective variables added significantly in predicting the quality of the mother-infant relationship. There were also significant interaction effects between the length of leave and these variables. Mothers who either reported more depressive symptoms or who perceived their infant as having a more difficult temperament and who had shorter leaves, compared with mothers who had longer leaves, were observed to express less positive affect, sensitivity, and responsiveness in interactions with their infants. The public policy implications of the relation between length of maternity leave, maternal and infant individual differences, and the quality of mother-infant interactions are discussed.  相似文献

This analog study examines the effect of hearing a child's cries on alcohol consumption, comprising one link in a possible association between drinking and child abuse. Thirty-two male undergraduate volunteers were preselected by age, drinking practices, and abuse potential. Subjects were assigned to either a high or low abuse potential group and were then randomly assigned to hear either an infant cry or a smoke alarm. Blood pressure was measured during each of three stimulus presentations. Following each presentation, the subject was asked to rate the stimulus on a number of different dimensions (e.g., soothing-arousing). Additionally all subjects participated in a subsequent taste-rating task as an unobtrusive measure of alcohol consumption. The results indicate that, regardless of risk group, subjects who listened to the infant cry consumed significantly more alcohol (M = 206 ml, SD = 126.43) during the taste-rating task than did those who heard only the smoke alarm (Mr = 95.68 ml, SD = 62.94) which was also rated as aversive. There was no relationship between abuse potential and alcohol consumption. Although diastolic blood pressure did not differ between groups, analysis of the infant rating scales revealed that, regardless of risk group, subjects who heard the infant cry reported feeling more aversion, arousal, and distress, than did those who heard the smoke alarm. These results lend additional support to studies depicting the infant cry as a stressful and aversive event, capable of eliciting increased drinking. Implications for arousal reduction by alcohol and a model of alcohol-induced child abuse are discussed.  相似文献

The American Academy of Pediatrics recently removed nicotine from the category of drugs contraindicated during breastfeeding. Little evidence demonstrates that infants exposed to nicotine through breastfeeding experience increased health risks beyond the airborne risks associated with passive smoking. The purpose of this longitudinal, five-week, quasi-experimental pilot study was to determine whether "smoking hygiene," an educational intervention, reduces the frequency of respiratory symptoms experienced by infants whose mothers both smoke and breastfeed. Twenty-nine mother-infant pairs entered the study with 28% dropping out. Of the 21 mother-infant pairs who completed the study, 66% of the nine infants in the control group experienced respiratory illness, compared to 42% of the 12 infants in the intervention group (x2 = .814; p > .05). Thus, the difference was statistically nonsignificant in this small sample, but the trend worsened the anticipated direction. The study demonstrates some of the difficulties of intervening with this group of mothers.  相似文献

ObjectiveThis study assessed infant disposition and health outcomes among offspring born to mothers without prenatal care, based on maternal characteristics and the reason for lack of prenatal care (i.e., denial of pregnancy, concealment of pregnancy, primary substance use, financial barriers and multiparity).MethodsA retrospective record review was completed at an urban academic medical center. Subjects were women who presented at delivery or immediately postpartum with no history of prenatal care (N = 211), and their infants.ResultsInfants of mothers with substance use problems had the highest rates of referral to child protective services and out-of-home placement at discharge, though mothers with other reasons for no prenatal care also experienced both referral and placement. Infants born to mothers using substances experienced the highest rates of neonatal intensive care unit admission, and the lowest mean birth weight.ConclusionsThough those without prenatal care experienced a variety of adverse outcomes, substance use problems were most frequently correlated with adverse infant outcomes. Mothers who either had lost custody of other children or with substance use problems were at highest risk of losing custody of their infants. Those who denied or concealed their pregnancy still frequently retained custody.Practice implicationsAmong mothers without prenatal care, those with substance use problems were least likely to retain custody of their infant at hospital discharge. Custody status of the mother's other children was also independently associated with infant custody. Mothers who denied or concealed their pregnancy still often retained custody. Referrals of mothers with no prenatal care for psychiatric evaluation were rare, though referrals to social work were frequent. Child protective services occasionally did not investigate referrals in the denial and concealment groups. Healthcare providers should be aware of the medical and psychological needs of this vulnerable population of infants and mothers.  相似文献

40 mothers and their 12-month-old infants were observed twice at home by 2 observers for 2 hours. After the second visit, the observers described the infant using the Waters Attachment Behavior Q-sort and the mother's interactive behavior with the Maternal Behavior Q-sort developed by the present authors and Ainsworth's rating scales. Maternal sensitivity was unrelated to maternal age, income, or SES, but correlated positively with maternal education. Mothers of more difficult children were less sensitive. A strong relation was found between infant attachment and maternal sensitivity as measured by the Maternal Behavior Q-sort and by the Ainsworth scales. Using the Q-sort procedure, mothers of more secure infants were more frequently characterized as noticing their babies' signals and using these signals to guide their behavior; they also were more knowledgeable about their infant and appeared to enjoy them more than mothers of less secure infants.  相似文献

Infants are increasingly cared for by adults other than their parents. Here we describe non-parental infant care within a diverse cohort; and investigate the relationship between parents’ antenatal intentions and actual infant care. 6822 New Zealand women were recruited during pregnancy and asked about their intentions for childcare. Non-parental care was assessed when infants were nine months old: 1717 (25%) of the 6853 cohort children were receiving more than 8 h per week of regular non-parental care. In comparison with infants of European mothers, infants of Asian or Pacific mothers were more likely to be cared for by extended family; and infants of Māori mothers were more likely to receive centre-based care. Infants from families with lower household incomes, living in more deprived areas were more likely to be cared for by family. When their infants were nine months old, mothers from low- to medium-income households were less likely to be using the type of non-parental care they had intended antenatally, and the same was true when their children were aged 2 years.  相似文献

IN THIS COLUMN, THE AUTHOR EXAMINES RECENT RESEARCH ON TWO SEPARATE TOPICS: 1) breastfeeding; 2) postpartum length of hospital stay. Recent studies suggest long-term effects of breastfeeding that benefit both mother and infant. Benefits include a reduced risk of breast cancer in breastfeeding mothers and a reduced level of total and LDH cholesterol in adults who were breastfed as infants. Infants of mothers with maternal asthma had lower rates of asthma if the mother breastfed. In a study of women in the United States who planned to breastfeed, those mothers who breastfed exclusively and planned to breastfeed more than three months were more likely to achieve their goals than mothers who planned to combine breast and human-milk substitute feeds and to breastfeed less than three months.In a Canadian study, shortened postpartum stays led to increased re-admission to hospital for mothers with cesarean births. In contrast, in a Massachusetts study, shortened postpartum stays did not lead to an increase in infant visits for urgent care. However, the Massachusetts study did not reflect a decrease in maternity-related costs associated with shortened length of postpartum stay.  相似文献

40 middle-class mothers and their 12-month-old infants participated in an examination of the extent to which infant sociability and infant home experiences were correlated with cognitive capacity. Results indicated that the measures of the home environment (including Caldwell's Home Observation for Measurement of the Environment [HOME] inventory) were not correlated with the measures of cognitive competence (Bayley Mental Development Index [MDI], Ordinal Scales of Psychological Development) except among firstborns. Measures of the home environment were, however, correlated with measures of infant sociability (assessed inside and outside the test situation): sociable infants had sociable mothers. The infants' reactions to strange adults clearly influenced their performance in testing situations. Strong relationships were found between both measures of sociability and both measures of cognitive competence. The sociable friendly infants received higher scores on both cognitive tests than the less sociable babies did.  相似文献

This study investigated the relation between crying and infant abuse in group-living rhesus monkeys (Macaca mulatta). The subjects were 10 abusive mothers with their infants and 10 control mother-infant pairs. Abused infants cried more frequently than controls in the first 12 weeks of life, even when cries immediately following abuse were excluded from the analysis. The coos of 5 abused infants differed from those of 5 controls in several acoustic parameters, whereas their screams and geckers were acoustically similar, when recorded in the same context. Abusive mothers were less likely than control mothers to respond positively to the cries of their infants. Although infant cries may increase the probability of abuse being repeated, infant crying per se does not appear to be a major determinant of abuse.  相似文献

This study was designed to test the hypothesis that increased physical contact, experimentally induced, would promote greater maternal responsiveness and more secure attachment between infant and mother. Low-SES mothers of newborn infants were randomly assigned to an experimental group (n = 23) that received soft baby carriers (more physical contact) or to a control group (n = 26) that received infants seats (less contact). Using a transitional probability analysis of a play session at 31/2 months, it was demonstrated that mothers in the experimental group were more contingently responsive than control mothers to their infants' vocalizations. When the infants were 13 months old, the Ainsworth Strange Situation was administered. Significantly more experimental than control infants were securely attached to their mothers. We infer from these results that for low-income, inner-city mothers, there may be a causal relation between increased physical contact, achieved through early carrying in a soft baby carrier, and subsequent security of attachment between infant and mother.  相似文献

Trauma symptoms among infants exposed to intimate partner violence   总被引：5，自引：0，他引：5  
OBJECTIVE: To determine whether infants have a traumatic response to intimate partner violence (male violence toward their female partner; IPV) experienced by their mothers, two questions were explored: (1) Is the number of infant trauma symptoms related to the infant's temperament and the mother's mental health? (2) Does severity of violence moderate those relationships? METHODOLOGY: Forty-eight mothers reported whether their 1-year-old infants experienced trauma symptoms as a result of witnessing episodes of IPV during their first year of life. Mothers also reported on their own trauma symptoms that resulted from experiences of IPV. RESULTS: For those infants experiencing severe IPV and whose mothers exhibit trauma symptoms, we were able to predict whether infants exhibited trauma symptoms (b = .53, p < .01). This was not true for children who witnessed less severe IPV (b= -.14, ns). Maternal depressive symptoms and difficult infant temperament did not predict infant trauma symptoms for either group of infants. CONCLUSION: Mothers report that infants as young as 1-year-old can experience trauma symptoms as a result of hearing or witnessing IPV. The significant relationship between infant and maternal trauma symptoms, especially among those infants experiencing severe IPV, are consistent with the theory of relational PTSD. Findings suggest that interventions for mothers and families need to consider the influence of the severity of IPV on very young children.  相似文献

Maternal smoking during pregnancy retards fetal growth and depresses infant birth weight. The magnitude of these effects may be moderated by fetal genotype. The current study investigated maternal smoking, fetal genotype, and fetal growth in a large population sample of dizygotic twins. Maternal smoking retarded fetal growth in a dose-dependent fashion. In a subsample of 497 twin pairs whose mothers smoked during pregnancy, a functional polymorphism in the NAD(P)H:quinone oxidoreductase gene ( NQO1 Pro187Ser; rs1800566) was significantly associated with fetal growth within families. The effect was strongest among moderate smokers. This is the first demonstration that fetal genotype for an enzyme involved in tobacco smoke metabolism influences intrauterine growth independent of maternal genotype. Future studies should conduct formal tests of Fetal Genotype × Maternal Smoking interactions.  相似文献

This study examined the effects of maternal employment and separation anxiety on maternal interactive behavior and infant attachment. 73 mother-infant pairs participated in a laboratory free-play session when infants were 5 and 10 months of age and in the Strange Situation when the infants were 18 months of age. Maternal feelings about being separated from her infant were assessed by questionnaire at 5 months. Employed mothers returned to work before the infants' fifth month, and nonemployed mothers did not work outside the home through their infants' tenth month. Employed mothers who reported high levels of separation anxiety were more likely to exhibit intrusive behaviors at 10 months. While employment was not directly related to attachment, we found infants of high-anxiety employed mothers to develop anxious-avoidant attachments. The results suggest that maternal separation anxiety and interactive style may be important mediators between employment and later infant outcome.  相似文献

It has been assumed that subject loss in habituation procedures is most likely due to random factors such as the behavioral state of the infant during testing. This study explored the possibility that infant temperament might contribute to subject loss. 114 infants at 3 age levels (11, 18, and 28 weeks) were rated by their mothers on a temperament questionnaire and then subjected to a habituation procedure. Analyses showed that female infants who were unable to complete the habituation task were reported as being more fussy and unadaptable. Female infants were less likely to complete at least part of the procedure than were male infants. The results suggest that subject loss in habituation studies may be the result of nonrandom individual difference factors and not just the result of temporary fluctuations in state.  相似文献

48 mothers of 5-month-old infants were asked to estimate their control over the termination of an infant cry in a laboratory-simulated child-care task. Mothers who greatly overestimated their control differed from low or moderate "illusion-of-control" mothers by exhibiting a depression-prone attributional style, a depressed mood state, perceiving the father as participating less in child care, and responding to impending infant cries with heart-rate acceleration characteristic of aversive conditioning. At age 16 months, 40 of the mother-infant pairs participated in the Ainsworth Strange Situation. Insecure infant attachment at 16 months was associated with maternal perception of overcontrol, depressed mood state, and aversive conditioning to the impending cry in the laboratory task at the 5-month period.  相似文献

Self-report and behavioral observation procedures were used to assess the quality of mothers' interactions with facially deformed infants. This assessment strategy also provided an opportunity to evaluate the hypothesis that parents of facially deformed infants may deny or be unaware of deficits in their relationships with these children. 10 mothers, 5 with unattractive/craniofacially deformed infants and 5 with normal infants, completed self-report measures of stress, social support, satisfaction with parenting, and general life satisfaction. Mother-infant interactions were videotaped and rated on discrete and global behavioral measures. Results revealed that mothers of deformed infants rated their parental satisfaction and current life satisfaction more positively than did mothers of normal infants. However, these same mothers were observed to behave in a consistently less nurturant manner than mothers of normal children. These results suggest that infant facial deformity/unattractiveness may affect the quality of infant-caregiver interactions without parental awareness.  相似文献
