Abstract
BACKGROUND AND OBJECTIVES As outcomes for extremely premature infants improve, up-to-date, large-scale studies are needed to provide accurate, contemporary information for clinicians, families, and policy makers. We used nationwide New Zealand data to explore the impact of gestational age on health and educational outcomes through to adolescence. METHODS We performed a retrospective cohort study of all births in New Zealand appearing in 2 independent national data sets at 23 weeks' gestation or more. We report on 2 separate cohorts: cohort 1, born January 1, 2005 to December 31, 2015 (613 521 individuals), used to study survival and midterm health and educational outcomes; and cohort 2, born January 1, 1998 to December 31, 2000, and surviving to age 15 years (146 169 individuals), used to study high school educational outcomes. Outcomes described by gestational age include survival, hospitalization rates, national well-being assessment outcomes at age 4 years, rates of special education support needs in primary school, and national high school examination results. RESULTS Ten-year survival increased with gestational age from 66% at 23 to 24 weeks to >99% at term. All outcomes measured were strongly related to gestational age. However, most extremely preterm children did not require special educational support and were able to sit for their national high school examinations. CONCLUSIONS Within a publicly funded health system, high-quality survival is achievable for most infants born at periviable gestations. Outcomes show improvement with gestational ages to term. Outcomes at early-term gestation are poorer than for children born at full term.

Abstract
The following paper and its accompanying paper (Grantham-McGregor SM, et al. Effects of health and nutrition on cognitive and behavioural development in children in the first three years of life. Part 1: Low birthweight, breastfeeding, and protein-energy malnutrition. Food Nutr Bull 1999;20:53–75) review the literature on the conditions that are prevalent and considered to be likely to affect child development and are therefore of public health importance. the reviews are selective, and we have generally focused on recent work, particularly in areas that remain controversial. the reviews are restricted to nutritional and health insults that are important in the first three years of life. Where possible, we have discussed the better studies. This paper considers the effects of infections and the major micronutrient deficiencies: iodine, iron, and zinc.

Abstract
Housing affects the health of children and youth. One-third of households in Canada live in substandard conditions or in housing need. The present statement reviews the literature documenting the impacts of housing on personal health and the health care system. Types of housing need are defined, including unsuitable or crowded housing, unaffordable housing and inadequate housing, or housing in need of major repairs. The health effects of each type of housing need, as well as of unsafe neighbourhoods, infestations and other environmental exposures are outlined. Paediatricians and other physicians caring for children need to understand the housing status of patients to fully determine their health issues and ability to access and engage in health care. Recommendations and sample tools to assess and address housing need at the patient, family, community and policy levels are described. Canada is the only G8 country without a national housing strategy. Recommendations also include advocating for enhanced action at all levels of government and for housing-supportive policies, including a national housing strategy.

Abstract
Respiratory syncytial virus (RSV) is a serious pathogen causing significant mortality and morbidity, especially in premature infants and infants with chronic lung disease or significant congenital heart disease. Therapy for RSV infection is essentially supportive, although several new compounds are under investigation. Therefore, immunoprophylaxis to prevent severe RSV disease in high-risk infants assumes great significance. Palivizumab, a humanized monoclonal antibody to RSV, significantly reduces hospitalization in the first 6 months in premature infants born at less than 35 weeks, infants less than 24 months of age with chronic lung disease and requiring treatment in the last 6 months, and in children 24 months or younger with hemodynamically significant heart disease. A new ultrapotent anti-RSV antibody (MEDI-524) appears to be more effective in animals than palivizumab and is undergoing clinical evaluation. There has been considerable progress in the development of vaccines; namely subunit, live attenuated, genetically recombinant virus and polypeptide vaccines. Plasmid DNA vaccines coding for parts of the F and G surface glycoproteins and vaccinia vector vaccines are also being evaluated. Maternal immunization has the potential to prevent RSV disease in early infancy. RSV prophylaxis has seen tremendous progress in the last decade.

Abstract
There is major untapped potential to improve health in low-income communities through improved housing design, fittings, materials and construction. Adverse effects on health from inadequate housing can occur through a range of mechanisms, both direct and indirect, including as a result of extreme weather, household air pollution, injuries or burns, the ingress of disease vectors and lack of clean water and sanitation. Collaborative action between public health professionals and those involved in developing formal and informal housing could advance both health and development by addressing risk factors for a range of adverse health outcomes. Potential trade-offs between design features which may reduce the risk of some adverse outcomes whilst increasing the risk of others must be explicitly considered.

Abstract
No longitudinal study should go into the field prior to detailed piloting and validation studies of the measures and techniques to be used. Preparation should also involve the training of staff, the acquisition of space and appropriate equipment, and liaison with the community and ethical committees as well as with scientific collaborators. Because different measures will continually be introduced as the participants age, the preparation, piloting and validation studies have to be ongoing. Here we describe some of the different strategies that should be used.

Abstract
BACKGROUND Housing is a key determinant of child and youth health. A significant number of Canadian children and youth are living in housing need, but information regarding the housing status of children and youth in the Ottawa, Ontario, community is lacking. OBJECTIVE To examine the housing status of children and youth accessing emergency health services at the Children's Hospital of Eastern Ontario (Ottawa, Ontario), and the factors associated with housing status. METHODS Youth and families of children registered at the Children's Hospital of Eastern Ontario's emergency department were offered a questionnaire. Affordability, adequacy, suitability and stability of housing were evaluated through self-reporting. Housing need was defined as an inability to meet one or more of these criteria. Associations among housing and household composition, demographics and weight-for-age percentiles were examined. RESULTS One thousand three hundred sixty surveys were completed. Fifty-four per cent of respondents (663 of 1224) were living in housing need, including 33% of respondents (381 of 1166) who were living in unaffordable housing. Single-parent families (OR 2.82), families with six or more members (OR 2.51) and families who rented (OR 5.27) were more likely to be living in housing need. Children and youth with a primary care physician were more likely to be living in stable housing (OR 0.41). Unsuitable housing was associated with extreme weight-forage percentiles (OR 1.90). CONCLUSION More than one-half of the children and youth in the present study were living in housing need. Health care providers have a responsibility to identify and understand the determinants of health of their patients, including housing, and to work for the improved health of their patients and their communities.

Abstract
The influence of physical housing quality on childhood asthma expression, especially the effect of exposure to moulds, allergens, and pollutants, is well documented. However, attempts to explain increasing rates and severity of childhood asthma solely through physical environmental factors have been unsuccessful, and additional exposures may be involved. Increasing evidence has linked psychological stress and negative affective states to asthma expression. At the same time, recent scholarship in the social sciences has focused on understanding how social environments, such as housing, "get under the skin" to influence health, and suggests that psychological factors play a key role. While there is relevant overlapping research in social science, psychology, economics, and health policy in this area, findings from these disciplines have not yet been conceptually integrated into ongoing asthma research. We propose to expand the dimensions of housing considered in future asthma research to include both physical and psychological aspects which may directly and indirectly influence onset and severity of disease expression. This synthesis of overlapping research from a number of disciplines argues for the systematic measure of psychological dimensions of housing and consideration of the interplay between housing stress and physical housing characteristics in relation to childhood asthma.

Abstract
BACKGROUND Despite great strides in improving prenatal care utilization among American women, key perinatal indicators have remained stagnant or worsened in the past decade, and the United States continues to rank near the bottom compared to other developed countries. A new approach is needed if we are to achieve improvements in perinatal health. METHODS To propose a new framework that integrates a "life span" approach with a multiple determinants model. RESULTS We recognize that (1) powerful influences on outcome occur long before pregnancy begins; (2) pregnancy outcome is shaped by social, psychological, behavioral, environmental, and biological forces; and (3) the demography of pregnancy has changed dramatically in the last few decades with more women delaying their first birth. Approaches that simultaneously consider the entire life span as well as multiple determinants may need to be adopted. We propose a framework that integrates these approaches and is supported by the research literature. The life span perspective focuses attention toward the preconceptional and interconceptional periods as targets for intervention in improving perinatal health. The multiple determinants model distinguishes among concepts of disease, health and functioning, and well-being for both women and their offspring. CONCLUSIONS Our intent is to influence how policymakers, public health professionals, clinicians, and researchers approach perinatal health.

Abstract
According to National Vital Statistics Reports, premature infants (< 36 weeks gestation) account for approximately 7.4% of all births. During the 8 years from 1989 to 1997, multiple births steadily increased across all categories from twin to quintuplet and higher orders. During that same period low birth weight (< 2500 g) births increased almost 12%, and very low birth weight (< 1500 g) births increased approximately 20%.Attendant to these national trends in multiple and preterm births, overall gestation-specific survival rates have improved substantially. This improved outcome can be attributed in large measure to advances in neonatal care and technology. Despite the encouraging statistics on survival, infants born prematurely, at low or very low birth weights and/or with chronic conditions that predispose to lower respiratory tract illness, continue to incur serious risk of long term morbidity and the consumption of inpatient hospital services. In a recent 2-year study of US children, low and very low birth weights were found to be independent risk factors for bronchiolitis-associated mortality. In the past 14 years what defines bronchopulmonary dysplasia (BPD)/chronic lung disease (CLD) has shifted away from clinical, radiographic and pathologic findings in the preterm infant toward the pathophysiology of arrested lung development and the need for supportive care beyond 36 weeks corrected gestational age. The incidence of BPD/CLD ranges from 14 to 43%, with higher rates observed among infants of lower gestational age and birth weight. The health care team approach to the management of BPD directs its efforts toward minimizing pulmonary vascular resistance, alleviating airway obstruction and improving short term lung mechanics. Measures to prevent BPD/CLD attempt to forestall both acute and chronic lung function abnormalities. To that end researchers have investigated the early use of continuous positive airway pressure, vitamin supplementation and recombinant human copper/zinc superoxide dismutase. Despite significant gains in the survival of infants born at lower gestational ages, prematurity, low birth weight and/or underlying chronic pulmonary disease put the pediatric patient at risk for increased frequency and severity of respiratory syncytial virus lower respiratory tract illness and the potential for its long term sequelae.

Abstract
Respiratory syncytial virus (RSV) was initially isolated in 1956. Since then it has become recognized as a major pathogen worldwide. It is a ubiquitous pathogen that produces seasonal epidemics. Primary infection occurs in children before 2 years of age. In older children and adults, RSV usually manifests itself as an upper respiratory tract infection. In immunecompromised patients, those with underlying cardiopulmonary disorders, premature infants, and other vulnerable individuals, RSV infection can produce severe bronchiolitis or pneumonia. In recent years we have observed exciting new information about the prevention of serious RSV infection in high-risk infants including infection control practices, active immunity and passive immunity. Two immunoprophylaxis products (RSV i.v. immune globulin and palivzumab) have been developed for clinical use in the prevention of serious RSV infection. Many other agents including vaccines, super monoclonal antibodies, and antivirals are under development. Although clinicians now have the ability to provide their most vulnerable patients with meaningful prevention strategies, much more needs to be done before we can regard RSV as a preventable disease.

Abstract
The use of gas stoves has been associated with respiratory symptoms of chronic airway inflammation and higher rates of respiratory infections. We used data from a 1992/93 survey of 2,198 East German school children (aged 5 to 14) to assess whether gas cooking increases respiratory symptoms and is associated with a chronic inflammatory process reflected by an increase in white blood cell (WBC) count in children who do not exhibit signs of an acute respiratory infection. We found increases for the respiratory symptoms 'cough without cold' [odds ratio (OR) = 1.68; 95% confidence interval (CI), 1.18-2.39], 'cough in the morning' (OR = 1.58; CI, 1.23-2.04) and 'cough during the day or at night' (OR = 1.42; CI, 1.13-1.78) in children living in homes with gas ranges, but lifetime prevalence of asthma, bronchitis, wheeze, and the prevalence of acute infections were not affected. Furthermore, we examined WBC levels in a subgroup of 1,134 children for whom blood samples were available and who did not suffer from an acute infection. We observed small increases in the risk of having WBC counts above the 75th or 90th percentile (8300 or 9800 cell counts per microliter) when children were exposed to gas cooking after adjustment for age, gender, and passive smoking (OR = 1.30; CI, 0.98-1.73, and OR = 1.38; CI, 0.91-2.10). The strongest effect estimates for chronic inflammation were found for those children likely to have been exposed at higher levels, that is when stoves had no fans, in smaller homes, and for children spending more time indoors.
