Abstract:
Sudden infant death syndrome (SIDS) is associated with maternal smoking during pregnancy. However, the relationship between tobacco exposure during infancy and SIDS is unknown. The examination of infants whose mothers smoked only after pregnancy will help determine the relationship between passive cigarette exposure during infancy and SIDS risk. This case-control analysis used data on normal birth weight (≥2500 g) infants included in the National Maternal and Infant Health Survey, a nationally representative sample of approximately 10 000 births and 6000 infant deaths. Infants were assigned to one of three exposure groups: maternal smoking during both pregnancy and infancy (combined exposure), maternal smoking only during infancy (passive exposure), and no maternal smoking. SIDS death was determined from death certificate coding. Logistic regression was used to adjust for potentially confounding variables. Infants who died of SIDS were more likely to be exposed to maternal cigarette smoke than were surviving infants. Among black infants the odds ratio was 2.4 for passive exposure and 2.9 for combined exposure. Among white infants the odds ratio was 2.2 for passive exposure and 4.1 for combined exposure. After adjustment for demographic risk factors, the odds ratio for SIDS among normal birth weight infants was approximately 2 for passive exposure and 3 for combined exposure for both races. These data suggest that both intrauterine and passive tobacco exposure are associated with an increased risk of SIDS and are further inducement to encourage smoking cessation among pregnant women and families with children.

Abstract:
Osteopenia, rickets, and fractures from nutrient deficiencies can occur during infancy, particularly in preterm infants. Bone mass accretion during the first year of life is equal to or greater than that achieved at any other stage of life, including adolescence. Optimizing calcium and bone status during infancy can have immediate benefits in maintaining calcium homeostasis and preventing disturbances in bone mineralization and can provide long-term benefits by helping infants to later reach their maximum genetic potential for peak bone mass, a prerequisite for the prevention of osteoporosis and its complications. Dietary calcium requirements during infancy generally reflect the need to achieve normal growth and bone mineralization because 99 percent of total body calcium is present in the skeleton. Knowledge of physiologic factors that determine infant calcium requirements and the bioavailability of calcium from various dietary sources is important to ensuring bone health during infancy. Also key are the practical issues related to optimizing calcium nutriture in infants born at term and prematurely.

Abstract:
Little is known about the impact of less healthy snack foods on weight trajectories during infancy. This secondary analysis of data from the Nurture cohort explored prospective associations of less healthy snack foods with infant weight trajectories. Pregnant women were recruited and, upon delivery of a single live infant, 666 mothers agreed to participate. Mothers completed sociodemographic and infant feeding questionnaires, and infant anthropometrics were collected during home visits at 3, 6, 9, and 12 months. Less healthy snack food consumption was assessed by asking how frequently baby snacks and sweets were consumed each day during the previous three months. Multilevel growth curve models explored associations of baby snacks and sweets with infant weight-for-length (WFL) z-scores. On average, mothers were 27 years old, 71.5% were non-Hispanic Black, and 55.4% had household incomes of ≤$20,000/year. Consumption of less healthy snack foods increased during infancy with a median intake of 3.0 baby snacks/day and 0.7 sweets/day between 10 and 12 months. Growth curve models showed that infants who consumed sweets >2 times/day had significantly higher WFL z-scores during the second half of infancy compared to infants who never consumed sweets. Less healthy snacks may contribute to the risk of obesity during infancy and promoting healthy snack food choices during this critical time is important.

Abstract:
Caregivers at an institution for motherless infants in rural Tanzania participated in focus group interviews and participant observations. This paper aims at describing how they perceive infancy, caring and sensitivity in their everyday context. It adds knowledge from Tanzania about institutional infant care and the concept of sensitivity in caregiving, based on an approach sensitive to culture and context. The main result is that the caregivers are most concerned with fulfilling the infants’ physical needs. They defined infants’ social and emotional needs in a variety of ways and gave accounts about what sensitivity in caring for infants meant in their context. They also described their workload, their burdens and their strengths, and demonstrated shortcomings in fulfilling the infants’ social and emotional needs. Interventions to promote emotional and social support in addition to fulfilling physical needs are crucial.

Abstract:
An understanding of how infant eating behaviour relates to later obesity is required if interventions in infancy are to be attempted. The aim of this paper is to review findings from the Gateshead Millennium Study to describe (i) what we have already established about the relationship between infant feeding transitions, infancy weight gain and eating behaviour and (ii) describe new analyses that examine how infant eating behaviour and temperament relate to infancy weight gain and childhood adiposity. The Gateshead Millennium Study recruited 1029 infants at birth and parents completed questionnaires five times in the first year. We have already described how starting solids and ceasing breast-feeding seems to be a response to rapid early weight gain, rather than a cause, and that parents identify and respond to the individual appetite characteristics of their child. A number of questions about eating behaviour at 12 months were used to construct an infancy eating avidity score that was positively associated with height at age 7–8 years, but not with an adiposity index constructed using bioelectrical impedance, waist and skinfolds. Infancy eating avidity score was associated with greater fussiness and lower satiety responsivity on the Child Eating Behaviour Questionnaire at age 6–8 years. Temperament measured at age 6 weeks and 8 months showed no consistent associations with either infancy weight gain or adiposity at 6–8 years. While infancy may seem a logical time to intervene with children at risk of future obesity, the collective findings from this substantial population-based study largely suggest otherwise.

An Italian translation of the Infant Behavior Questionnaire-Revised (IBQ-R) was developed and evaluated with 110 infants, demonstrating satisfactory internal consistency, discriminant validity, and construct validity in the form of gender and age differences, as well as factorial integrity. Cross-cultural differences were subsequently evaluated for matched samples of Italian and United States (US) (N = 110) 3—12-month-olds. Across infancy, parents of US infants reported higher levels of activity, high and low intensity pleasure, and vocal reactivity, whereas Italian infants, particularly males, were rated higher on cuddliness. In early infancy only, US infants were viewed as higher on high intensity pleasure and perceptual sensitivity.

Abstract:
Sleep during infancy is important for the well-being of both infant and parent. Therefore, there is large interest in characterizing infant sleep with reliable tools, for example by combining actigraphy with 24-h-diaries. However, it is critical to select the right variables to characterize sleep. In a longitudinal investigation, we collected sleep data of 152 infants at ages 3, 6, and 12 months. Using principal component analysis, we identified five underlying sleep composites from 48 commonly-used sleep variables: Sleep Night, Sleep Day, Sleep Activity, Sleep Timing, and Sleep Variability. These composites accurately reflect known sleep dynamics throughout infancy as Sleep Day (representing naps), Sleep Activity (representing sleep efficiency and consolidation), and Sleep Variability (representing day-to-day stability) decrease across infancy, while Sleep Night (representing nighttime sleep) slightly increases, and Sleep Timing becomes earlier as one ages. We uncover interesting dynamics between the sleep composites and demonstrate that infant sleep is not only highly variable between infants but also dynamic within infants across time. Interestingly, Sleep Day is associated with behavioral development and therefore a potential marker for maturation. We recommend either the use of sleep composites or the core representative variables within each sleep composite for more reliable research.

Abstract:
Children with frequent respiratory symptoms in infancy have an increased risk for later wheezing, but the association with symptom dynamics is unknown. We developed an observer-independent method to characterise symptom dynamics and tested their association with subsequent respiratory morbidity.In this birth-cohort of healthy neonates, we prospectively assessed weekly respiratory symptoms during infancy, resulting in a time series of 52 symptom scores. For each infant, we calculated the transition probability between two consecutive symptom scores. We used these transition probabilities to construct a Markov matrix, which characterised symptom dynamics quantitatively using an entropy parameter. Using this parameter, we determined phenotypes by hierarchical clustering. We then studied the association between phenotypes and wheezing at 6 years.In 322 children with complete data for symptom scores during infancy (16 864 observations), we identified three dynamic phenotypes. Compared to the low-risk phenotype, the high-risk phenotype, defined by the highest entropy parameter, was associated with an increased risk of wheezing (odds ratio (OR) 3.01, 95% CI 1.15–7.88) at 6 years. In this phenotype, infants were more often male (64%) and had been exposed to environmental tobacco smoke (31%). In addition, more infants had siblings (67%) and attended childcare (38%).We describe a novel method to objectively characterise dynamics of respiratory symptoms in infancy, which helps identify abnormal clinical susceptibility and recovery patterns of infant airways associated with persistent wheezing.

Connors, Elizabeth. "Mother-infant interaction and the development of mastery motivation in infancy." Thesis, University of Central Lancashire, 1995. http://clok.uclan.ac.uk/20037/.

Full text
Abstract:
Infant motivation towards competence or mastery is said to be enhanced by contingent environmental feedback (White, 1959). This theory has been supported by research into the contingent responsiveness of the infant caretaking environment (e.g. Vondra & Belsky, 1989). Other caregiving variables have also been found to contribute such as the provision of sensory stimulation, focusing infant attention and low restrictiveness (Belsky, Goode & Most, 1980, Jennings, Harmon, Morgan, Gaiter & Yarrow, 1979; Yan-ow, Morgan, Jennings, Harmon & Gaiter, 1982). However, findings have been inconsistent. The first aim of the present study was to clari& previous research findings and, more specifically, to determine the importance of contingent experience in the first half year of life to the development of mastery motivation as this period has hitherto been neglected. Secondly, as the experience of social contingencies early in infancy has also been found to be associated with security of infant-caregiver attachment (Ainsworth, Blehar, Waters & Wall, 1978), it was hypothesised that there would be a relationship between infant attachment and mastery motivation. Finally, on the basis of findings that more difficult infants may experience less responsive maternal caregiving (van den Boom, 1989), it was proposed that infant difficultness would also be related to mastery motivation. 55 Mother-infant pairs were observed in everyday home interaction at 3 '/2, 8 and 14 months. Maternal contingent responsiveness, sensitivity, warmth, stimulation, infant attention focusing, restrictions and intrusive/insensitive behaviour were studied in relation to infant social and inanimate interaction. Mothers completed the ICQ (Bates, Freeland & Lounsbury, 1979) as a measure of infant diThcultness at each of the three stages. At 8 and 14 months infant mastery motivation was examined using a standard free-play procedure (Vondra & Belsky, 1991). Finally, infant attachment was measured at 14 months using the Attachment Behaviour Q-sort (Waters, 1987). Findings revealed that maternal contingent responsiveness to infant social initiations and distress, stimulation and focusing infant attention, measured at various stages of the study were positively correlated with aspects of infant mastery motivation measured at 8 and 14 months. Restrictions and intrusive/insensitive behaviour were found to be negatively correlated with infant mastery motivation. Stepwise regression indicated that the most significant predictors of 8 month mastery motivation were maternal warmth measured at 3 '/2 months and stimulation and intrusive/insensitive behaviour measured at 8 months. Responsiveness to infant distress and maternal intrusive/insensitive behaviour, both measured at 3 1/2 months, were found to be significant predictors of 14 month mastery motivation, thus, providing evidence of the importance of contingent responding during the early infancy period. However, intrusive/insensitive behaviour and contingent responsiveness to infant social initiations measured at 14 months were also significant predictors of 14 month mastery motivation. A moderate, but significant relationship was found between infant Attachment Q-sort scores and one measure of 14 month mastery motivation which indicated that more securely attached infants explored at a higher level of sophistication and showed greater pleasure in free-play. Stepwise regression indicated that the strongest predictors of 14 month infant attachment security were maternal warmth measured at 3 1/2 and 14 months and maternal sensitivity measured at 8 months. Contingent responsiveness at 3 1/2 months was not found to be of special significance to the development of secure attachment. Finally, infants rated as more difficult by their mothers performed more poorly along several measures of both 8 and 14 month mastery motivation than infants rated as less difficult. Infants who were perceived as more difficult had experienced higher levels of physical stimulation and more intrusive/insensitive caregiving during the first year. These findings show that infant mastery motivation may be influenced from an early age by both the behaviour of caregivers and by infant dispositional characteristics. Thus, there are important implications for the development of infants who, due to various disabilities, have difficulty in eliciting contingent responses from their caregivers or who, for whatever reason, may be perceived as difficult. The study focused on motivation for mastery of the inanimate environment and it is acknowledged that some infants may instead be predisposed or channelled towards mastery in the social environment. Further research is required to identi& individual differences in mastery orientation and to determine the longer term motivational consequences of early infant experiences.

Full text
Abstract:
This thesis is about infancy, independence, and how medicalisation shapes mothers' perceptions of their infants. It draws on ethnographic research in Cardiff, undertaken during a period of heightened concern about the Sudden Infant Death Syndrome (SIDS), and funded by the Foundation for the Study of Infant Deaths. Three "cultural constructions" of infancy are juxtaposed: the vulnerable and constantly accompanied Bangladeshi infant, the Welsh or English infant encouraged towards independence, and the autonomous infant of epidemiological analysis. The thesis shows how the processes of medicalisation brought contrasting perceptions of infancy to light, suggesting that Bangladeshi women taking part in an "English for Pregnancy" project were not only learning language, but also learning about medicalised infant care. It argues too that health professionals shape the way in which mothers perceive their infants through the introduction of the language of "risk factors". The infant body itself emerged at the boundary of powerful systems of meaning. If the boundaries of the Bangladeshi infant body were blurred through constant contact, those of the Welsh or English infant were marked intermittently through alternating periods of solitude with "attention". Some Welsh and English mothers spoke of infants and their care in terms of the care of domestic animals, and the mothers' own ambivalence about their own animality, while some Bangladeshi mothers spoke of the spiritual power and vulnerability of infants, and in doing so articulated their links with Bangladesh. For health professionals the infant body was a site for demonstrating expertise through both research (which constructed ethnic minorities as 'natural') and recommendations for action. The thesis discusses the location of contemporary anthropology at cultural boundaries. Juxtaposing contrasting beliefs about infancy revealed very different perceptions of independence, marked in particular by contrasting perceptions of time, space, and the infant body itself.

Abstract:
This thesis is concerned primarily with the measurement of total energy expenditure in infancy. Until the advent and subsequent development of the doubly labelled water technique for the assessment of carbon dioxide production rate in "free-living" individuals measurements of total energy expenditure in infants and children were virtually impossible. Thus measurements of total energy expenditure using this relatively new technique are of burgeoning interest to nutritionists, clinicians and human biologists.

Full text
Abstract:
Over the course of infancy and early childhood, major changes in visual function occur. A clear understanding of these changes could lead to a more complete understanding of adult vision, because a good theory of vision must parsimoniously account for infant and adult vision and for the smooth transition between them that occurs during normal maturation. This paper summarizes what is known of rod and cone vision in human infants. We include morphology of the rods and cones, psychophysically measured absolute and increment thresholds, photosensitivities and spectral sensitivities of the receptor mechanisms, and the overall luminous efficiency function. The ability to discriminate between lights on the basis of differences in spectral composition emerges over the first three months of life. Four hypotheses are discussed concerning what critical immaturities are responsible for the poor color vision of very young infants: (1) a color vision deficiency of a recognized adult type, (2) extrafoveal detection of stimuli, (3) inadequate spatial resolution for chromatic stimuli, and (4) immaturity of chromatically opponent channels.

Abstract:
Studies of the development of hyperacuity and motion perception in infants afford a splendid opportunity to examine longitudinally the visual factors which contribute to these visual functions. Adult hyperacuity is thought to depend on resolution acuity, contrast sensitivity, and spatial sampling. The developmental time course of hyperacuity in infants is compared with the development of acuity and contrast sensitivity, and with the maturation of the fovea. Stereoacuity and Vernier acuity follow similar developmental time courses in infants. While psychophysical evidence in adults demonstrates that stereo and Vernier acuity have different physiological substrates, the strong correlation during infancy indicates that they may be limited by a common factor during development.

Abstract:
Abstract Pulmonary artery stenosis (PAS) is a common complication of heart surgery in infancy. With recent advances in low profile-small diameter stent technology, PA stenting is now often performed in infants. While PAS stenting in older children does not impact distal PA growth and multiplication, in infants still undergoing significant PA growth, the impact of PA stent timing on long term PA development is unknown and potentially important. In a swine PAS model, the effects of early and delayed stent interventions on PA growth and cardiac function were comprehensively assessed. PA stenting had a positive impact on hemodynamics, lung perfusion, and histology, but the timing of intervention, either early or late, does not make a significant difference.

Full text
Abstract:
We focus on gender and sexual diversity in the secondary school setting due to the important role that education systems play in reducing social distance between individuals. Adolescence is also a crucial stage in which individuals construct their identities, develop their personalities, and have a tendency to experiment. Moreover, adolescence is a stage in which the levels of bullying and cyberbullying dramatically increase relative to infancy or puberty. LGBT students are particularly prone to being victimized in schools, yet there has been little work analyzing whether a larger presence of LGBT students in a classroom leads to more generalized violence.

Abstract:
Natural disasters are by no means new, yet the evolving understanding of their relevance to economic development and growth is still in its infancy. This paper summarizes the state of the economic literature examining the aggregate impact of disasters. The paper reviews the main disaster data sources available, discusses the determinants of the direct effects of disasters, and distinguishes between short- and long-run indirect effects. The paper then examines some of the relevant policy questions and follows up with projections about the likelihood of future disasters. The paper ends by identifying several significant gaps in the literature.

Abstract:
Analogous to the emergence of the internet, the introduction of blockchain technology augurs disruptive change to the music industry. Though in its infancy, the technology presents interesting policy issues related to registering and monetizing intellectual property, policing piracy, and creating and executing more flexible contracts between and among members in the music supply chain, among others. This paper assesses the ability of the distributed ledger technology to steer the industry toward a distributed model and its potential to drastically alter the entire music supply chain. It initiates a conversation about policy implications and how policymakers might address the issues related to adopting blockchain technology, including designing policies that support an environment that enables the well-deserved compensation of artists.

Agüero, Jorge M. Long-Term Effect of Climate Change on Health: Evidence from Heat Waves in Mexico. Inter-American Development Bank, January 2014. http://dx.doi.org/10.18235/0011535.

Full text
Abstract:
This paper uses year-to-year variation in temperature to estimate the long-term effects of climate change on health outcomes in Mexico. Combining temperature data at the district level and three rounds of nationally representative household surveys, an individual's health as an adult is matched with the history of heat waves from birth to adulthood. A flexible econometric model is used to identify critical health periods with respect to temperature. It is shown that exposure to higher temperatures early in life has negative consequences on adult height. Most importantly, the effects are concentrated at the times where children experience growth spurts: infancy and adolescence. The robustness of these findings is confirmed when using health outcomes derived from accidents, which are uncorrelated with early exposure to high temperatures.
