The evaluation of tailored and web-based information for new fathers.

BACKGROUND: Information and advice on infant health and development have been shown to be well received by new parents and to lead to more confident and nurturing parenting. However, in spite of the accumulating evidence highlighting the importance of fathers to the well-being of their families, fathers rarely access and utilize 'parenting' information. Tailored information for fathers delivered via email and Internet may provide an alternate route for support for fathers. This study aimed to assess father's readiness to utilize electronic information tailored to father's role. METHODS: Two hundred and fifty-three fathers from antenatal classes in two Australian cities were offered email and web-based information on seven topics: baby play, breastfeeding, post-natal depression, father-infant bonding, sex after birth, work-family balance and fussy babies. Of 137 who completed consent forms, a total of 105 fathers selected three topics and 67 fathers provided 149 topic evaluations. RESULTS: Most respondents were from managerial, professional or skilled occupations and had higher educational qualifications than the general population of fathers. The most popular topics were those that related to father-infant interaction (baby games and father-infant bonding), and the least popular were breastfeeding and sex after the birth. Respondents rated the information as satisfactory and most (78%) indicated that it changed their approach to fathering. Although the websites provided were available through the Internet, few fathers had previously accessed them. CONCLUSIONS: Information tailored to new father's perspectives provided through email or Internet may increase new fathers' access to useful knowledge and support. Important health topics such as breastfeeding may not currently be perceived as particularly relevant to fathers in the antenatal period. Portals designed to filter existing websites could facilitate the use of parenting information by new fathers.

Lead in the placenta, membranes, and umbilical cord in relation to pregnancy outcome in a lead-smelter community.

As part of a cohort study of the effects of chronic exposure to lead on pregnancy outcome and child development, lead concentrations in the umbilical cord and placental tissues (body and membranes) from 9 late fetal deaths, 23 preterm births, and 18 births associated with premature rupture of the amniotic membranes were compared with the lead concentrations in the tissues obtained at 22 normal births. Modest elevations in lead concentration were found in the placental body of late fetal deaths (stillbirths) and preterm births as well as in the cord tissue associated with preterm births and premature rupture of membranes. The geometric mean lead concentration in the membranes from late fetal deaths was 2.73 micrograms/g of dry tissue (95% confidence limits 0.69-10.8), which was 3.5 times higher than the mean found in normal births (0.78 micrograms/g, 95% confidence limits 0.61-1.00). The concentration in the membranes of preterm births was also significantly high, being 1.24 micrograms/G (0.91-1.67). Low correlations of membrane and antenatal blood lead concentrations suggest that other factors in addition to exposure to environmental lead may influence the amount of lead accumulated in the placental membranes.

The Port Pirie cohort study: maternal blood lead and pregnancy outcome.

During a three-year period, 831 pregnant women in and around Port Pirie, South Australia--a lead smelter community with longstanding lead pollution--were enrolled in a cohort study to examine prospectively the relation between body lead burden and pregnancy outcome. Three-quarters of the enrolled women were residents of the Port Pirie municipality; the other women lived in adjacent towns and countryside. At 14-20 weeks' gestation, the Port Pirie resident women had a mean blood lead concentration of 10.6 micrograms/dl, while the mean in the other (non-Port Pirie) women was 7.6 micrograms/dl. Similar differences were observed in maternal blood samples taken at 30-36 weeks, at delivery, and from the umbilical cord. These blood lead measures, in conjunction with information collected on other risk factors, were then examined in relation to pregnancy outcome. Among 749 pregnancies followed to completion, pre-term delivery was statistically significantly associated, in a dose-response manner, with maternal blood lead concentration at delivery. Mothers of late fetal deaths (stillbirths) had blood lead concentrations at 14-20 weeks' gestation similar to those of all the other women but had lower concentrations at delivery than the other women. Outcomes of pregnancy for which no association with blood lead was detected were spontaneous abortion, low birthweight (for births at term), intrauterine growth retardation, premature rupture of the membranes, and congenital anomalies.

Port Pirie Cohort study: childhood blood lead and neuropsychological development at age two years.

The Port Pirie Cohort Study is an ongoing prospective study of the relationship between exposure to environmental lead within a lead smelter community, and neuropsychological development in early childhood. Over 600 children, originally recruited during antenatal life, underwent serial blood lead estimations up to two years of age. Systematic interview information was collected on a range of variables, and formal developmental assessment (Bayley Scales of Infant Development) was carried out at 24 months of age. Blood lead concentrations measured antenatally (maternal), at delivery (maternal and umbilical cord) and postnatally at 6, 15 and 24 months were negatively correlated (p less than 0.05) with mental development at 24 months of age. Geometric mean blood lead concentrations (microgram/dl) were 14.3, 20.8 and 21.2 at 6, 15 and 24 months of age respectively. When multiple covariates, including maternal IQ, were controlled for in multiple regression analysis, a statistically significant (p less than 0.01) inverse association was observed between blood lead concentration (PbB) measured at 6 months of age and mental development at 2 years of age. No such association was evident for psychomotor development. When the quality of the home environment (HOME Score) was added to the multiple regression model, the inverse association between blood lead concentration at 6 months of age and mental development at 2 years persisted, albeit less strongly (p = 0.07). From this analysis, it is estimated that a child with with PbB of 30 micrograms/dl at age 6 months will have a deficit of 3.3 points (approximately 3%) on the Bayley Mental Development Scale relative to a child with PbB of 10 micrograms/dl.

Sociodemographic factors modifying the effect of environmental lead on neuropsychological development in early childhood.

A long-term prospective cohort study was conducted to examine the association between prenatal and postnatal exposure to environmental lead and childhood neuropsychological development. The possible interactive effects of blood lead and some covariates on early development were explored in this study. Our data suggest that gender of the child modifies the effect of lead on the neuropsychological development during early childhood. At the ages of 2 and 4 years, girls appear to be more sensitive than boys to the neuropsychological effects of lead. However, there is no significant modification of the effect of lead by some other covariates, such as parental smoking, socioeconomic status, home environment, birth weight, and the kind of infant feeding. Evidence of interactions between environmental lead exposure and other covariates in the causation of neuropsychological deficits in childhood underscores the desirability of considering both main effects and interactions in this area of research. Such effects, if confirmed, may have implications for public health intervention strategies.

Opportunistic blood lead testing in a paediatric inpatient population.

We report a simple protocol which has potential to estimate community paediatric blood lead levels using opportunistic testing. Permission to use leftover blood for a lead assay was sought from parents or guardians of 397 children one month to 13 years of age who were admitted to general paediatric wards of John Hunter Hospital, Newcastle, between May and August 1993 and who had blood for a full blood count taken for any reason. Results were reviewed by a medical officer and returned to parents. Where a child's blood lead level was of concern according to National Health and Medical Research Council guidelines, the child was referred to a specialist paediatrician for clinical assessment. Written consent was received from the parents or guardians of 95.5 per cent of eligible children (n = 379); 93.4 per cent of responders (354 of 379) had blood suitable for testing, giving an overall result rate of 89.2 per cent (354 of 397). The mean blood lead level for the whole group was 5.3 micrograms/dL. The highest blood lead level for any age group was 6.4 micrograms/dL in the 36 to < 60 month age group. Stratification by geographical area showed a trend in increasing blood lead with increasing population density and areas where lead polluting industries exist. The approximate cost per result achieved was $40. This opportunistic survey method provides a promising technique for obtaining data on community blood lead levels. It may be a practical and resource-efficient alternative to large-scale community surveys. Further studies are under way to validate the method as a community surveillance tool.

Does breastfeeding at six months predict cognitive development?

There is controversy over whether the method of feeding in infancy affects intellectual development. We investigated the relationship between breastfeeding status at 6 months of age and long-term cognitive development in a cohort of 375 children born in Port Pirie, South Australia, between 1979 and 1982. Cognitive assessments were conducted at ages 2, 4, 7 and 11 to 13 years. After adjustment for sociodemographic, environmental and biomedical factors, a small, statistically non-significant, beneficial effect of breastfeeding on cognitive functioning was observed. Compared with the bottle-fed children, the breast-fed children had a 3.4 (95% CI -0.1 to 6.9), 1.3 (-2.3 to 4.9), 1.2 (-2.0 to 4.4) and 0.8 (-1.9 to 3.5) point advantage on the Bayley Mental Developmental Index at age 2 years, the McCarthy General Cognitive Index at age 4 years and the Wechsler Full-Scale IQ at ages 7 and 11 to 13 years, respectively. Our data suggest that any beneficial effect of breastfeeding on cognitive development is quite small in magnitude.

Determinants of blood lead concentrations to age 5 years in a birth cohort study of children living in the lead smelting city of Port Pirie and surrounding areas.

Sources of variation and some principal determinants of blood lead concentration (PbB) were investigated in a cohort of children, followed to age 5 y, who were born near a lead smelter in Port Pirie, South Australia. The child's age and place of residence were the two variables most strongly predictive of PbB. A sharp increase in PbB occurred between 6 and 15 mo of age and was followed by a peak concentration that occurred at approximately 2 y of age, after which PbB steadily and consistently declined. Irrespective of age, the PbBs in children who lived in Port Pirie were significantly higher than levels identified in children who resided outside the city. There was no significant difference in PbB between boys and girls. Elevated PbB at each specific age was associated mainly with increased lead concentrations in the topsoil of the local residential area, employment of the father in the lead industry, parental smoking, and behaviors likely to cause ingestion of dirt. Blood samples taken from children at certain ages and during the warmer months contained more lead than samples obtained during the cooler months. The effects of these determinants on PbB during early childhood were basically consistent in both single and multivariable analyses.

Could your young patient have lead poisoning?

While clinical symptoms of classic lead poisoning are rare in Australian children, elevated body lead burden may have a small but treatable contribution to developmental and behavioural problems in individual children; its cumulative neurodevelopmental impact on populations of children is a greater public health concern. Children with blood leads over 15 micrograms/dL require blood lead monitoring and if persistently elevated assessment of potential environmental sources is indicated; children with lead levels over 25 micrograms/dL should be seen by a paediatrician. Chelation is not indicated in children with blood leads less than 55 micrograms/dL.

Psychosocial assessment of expectant fathers.

BACKGROUND: Comprehensive antenatal psychosocial assessment of mothers prior to the birth is established in many regions. While the influence of fathers on infant and maternal well-being is also recognised as commencing before birth, the early identification of needs among expectant fathers has not been addressed. METHODS: The current study surveyed fathers attending antenatal classes in public and private hospitals (n=307) in New South Wales, Australia, using psychosocial questions derived from the questions commonly asked in assessments of mothers. RESULTS: The most frequent responses suggest that fathers, at the time of the birth, have needs in regard to their ability to cope with the stresses of new parenthood and the skills and knowledge to care for their new baby. LIMITATIONS: Conclusions from the study are limited in their application to the population of expectant fathers by the low response rate and the low numbers of low-income, ethnic-background, and indigenous fathers in the sample. CONCLUSION: Assessment of fathers by psychosocial questions similar to mothers is advised to detect fathers who may require assistance and parenting education for fathers in infant care.

Injury surveillance: a key to effective control of childhood injuries.

Injuries account for 50% of deaths in Australian children aged 1-14 years, and are a major cause of hospital admission and disability. Injury surveillance systems involving the establishment of ongoing, systematic collection and analysis of data relevant to injury prevention and trauma management have a critical role in the effective control of the injury pandemic. Contemporary Australian initiatives including the establishment of the National Injury Surveillance and Prevention Project, new national public health programmes and research initiatives have the potential to establish a new wave of injury control programmes on a firm scientific base.

Resource allocation in contemporary paediatrics: the case against high technology.

High technology has introduced a new dimension to medical treatment. There are inevitable social costs as well as benefits, and the allocation of resources to high technology, as opposed to other areas of health care, is a contentious issue. The current balance in health service funding between high technology and low technology is not appropriate. It is driven by the technological imperative and only offers solutions to a limited number of problems. There is a scarcity of health resources left to develop intersectoral responses and provide adequate funding for research into person-intensive interventions suitable for many problems. Arguments against allocating too many resources to high technology in paediatrics are examined in this paper.

Child accident-mortality in the Northern Territory, 1978-1985.

The mortality in children who were aged 0-14 years in the Northern Territory in 1983-1985 was 2.5-times higher than it was for Australia generally over the same period. Total accidental-death rates over the period 1979-1983 in Aboriginal children were 2.2-times higher than in non-Aboriginal children. A trend towards an excess in Aboriginal child mortality was present in most categories except drowning and was particularly noteworthy for deaths due to natural and environmental causes (predominantly caused by box-jellyfish stings). Non-Aboriginal children experienced higher rates of death due to drowning than they did elsewhere in Australia; most of these occurred in domestic swimming-pools. A higher mortality was encountered in rural areas. The pattern of motor-vehicle-related deaths differed between Aboriginal children and non-Aboriginal children, with the former experiencing a greater number of deaths due to non-collision accidents that involved "loss of control". The implications of these findings for the development of appropriate preventive strategies is discussed.

Childhood injury mortality in New South Wales: geographical and socio-economic variations.

This paper reports a retrospective study of deaths due to unintentional injury in children aged between 0 and 14 years of age in New South Wales between 1985 and 1987. The aims were to determine whether the pattern of child injury mortality differed between rural and metropolitan New South Wales and to establish the relationship between socio-economic status, based on a geographical indicator of socio-economic status and child injury mortality. The child injury mortality rate for New South Wales in 1985-87 was 12.3 deaths per 100,000 population per year. The rate in the country area of 15.3 deaths per 100,000 was significantly higher than that for the metropolitan area of 11.3 per 100,000 (P < 0.05). Deaths of passengers in motor vehicle traffic accidents (P < 0.01) and deaths due to fires (P < 0.01) were greater in the country area. A negative linear association between socio-economic status and child injury mortality was found in the Sydney metropolitan area (P < 0.01). This trend was most apparent for deaths of child pedestrians (P < 0.01).

Differences in physical characteristics, perinatal histories, and social backgrounds between children with growth hormone deficiency and constitutional short stature.

Four hundred and forty-nine children with heights below -2.5 SD were identified by screening for height a total population of 48221 in three Scottish cities. Children participating in the study could be classified into 5 groups: severe growth hormone deficiency (n = 13), partial growth hormone deficiency (n = 25), low birthweight short stature (n = 34), constitutional short stature (n = 178), and short stature associated with some underlying disease (n = 106). Children with growth hormone deficiency tended to be shorter, were more likely to be obese, were growing more slowly, more often were the products of an abnormal pregnancy, and were less socially disadvantaged than constitutionally short children. Their parents were also more likely to have sought medical advice about the short stature. These findings have important implications for improved case-finding of children suffering from growth-hormone deficiency, who in this study accounted for about 10% of all short but otherwise normal children who came from non-disadvantaged communities.

Asthma knowledge, attitudes, and quality of life in adolescents.

Adolescents with asthma, their peers, and their teachers were studied in order to establish the level of knowledge concerning asthma and its management, their attitudes towards asthma, and the degree quality of life impairment due to asthma. A community survey was conducted among year 8 high school students (n = 4161) and their teachers (n = 1104). There was a good response rate to the questionnaires from students (93%) and teachers (61%). Twenty three per cent of students had asthma and this caused mild to moderate quality of life impairment, particularly with strenuous exercise. Asthma was provoked by passive smoke exposure in 30% of asthmatic students and up to 51% of students avoided situations because of asthma triggers. Asthma knowledge was low in teachers (mean score 14.90 out of a possible 31), students without asthma (11.25) and students with asthma (14.50). Specific knowledge on the prevention and treatment of exercise induced asthma was poor. There was a moderate degree of tolerance towards asthma among all three groups. Most considered internal locus of control as important, although students without asthma also considered chance to be a determinant of outcomes for people with asthma. Asthma is a common cause of quality of life impairment among year 8 high school students. Although specific knowledge on asthma is low, students and teachers hold favourable attitudes towards asthma. There are opportunities to intervene and improve asthma management among adolescents.
