The association of formula samples given at hospital discharge with the early duration of breastfeeding.

Conflicting results have been reported regarding the association of formula samples given at hospital discharge with breastfeeding duration. This study investigated the relationship between the distribution of formula samples and breastfeeding duration in low-income Hispanic women. A gift pack of formula was distributed randomly to 88 breastfeeding women. All women received a telephone call at one and three weeks to collect information about infant feeding. Chi-square analysis revealed no significant difference in the proportion of women exclusively breastfeeding at one week. However, fewer women were exclusively breastfeeding in the gift pack group at three weeks (p less than .004). Gift packs given to Hispanic breastfeeding women are associated with a decrease in exclusively breastfeeding during the first three weeks postpartum.

Congenital and maternal cytomegalovirus infections in a London population.

OBJECTIVE: To determine if women at risk of having babies infected with cytomegalovirus (CMV) can be identified antenatally. DESIGN: Prospective serological and demographic study of pregnant women and virological study of their newborn infants. SETTING: Teaching hospital in London. SUBJECTS: 3315 pregnant women and 2737 of their babies. MAIN OUTCOME MEASURES: Quantitative detection of CMV IgG antibodies; qualitative detection of CMV IgM antibodies; demographic characteristics of mothers; qualitative and quantitative titration of CMV viruria in newborn. RESULTS: Congenital CMV infection was found in nine newborn babies (0.33%) two of whom had symptoms. Serological testing of the nine mothers showed four primary and five recurrent infections; both of the symptomatic children were born in the latter group. Testing for CMV specific IgM antibodies or quantitation of IgG antibodies in early pregnancy sera could not differentiate those women at risk of giving birth to babies infected or damaged by CMV from the rest of the population. Quantitation of viruria confirmed that those babies most at risk of CMV disease have the highest titres of CMV. CONCLUSIONS: (i) Since laboratory tests in pregnant women cannot reliably identify fetuses at risk of disease, screening for asymptomatic maternal infection coupled with termination of pregnancy cannot be recommended. (ii) Since 'immune' women can still give birth to babies affected by CMV, we propose that future CMV vaccines should be used to immunize children with the aim of eradicating CMV infection in preference to selective immunization of sero-susceptible females.

Childhood morbidity and adulthood ill health.

STUDY OBJECTIVE: The aim of the study was to investigate the relationship between the state of health in childhood and ill health in early adult life. DESIGN: The study used data collected as part of the National Child Development Study and related health at 7 years of age to that at 23. A wide range of information on child health in the cohort was available, which was used to construct a broader measure of health status than selected diagnostic categories. SETTING: The survey population was nationwide. PARTICIPANTS: The study population included all children born in the week 3-9 March 1958. They were followed up at 7, 11, 16, and 23 years. Of the target population of 17,733 births, 12,537 (76%) were retraced and interviewed at 23. MEASUREMENTS AND MAIN RESULTS: Children at age 7 were allocated to 13 morbidity groups; 20% of children had reported no ill-health apart from the common infectious diseases, but 10% were included in four or more of the morbidity groups. Children with no reported morbidity retained their health advantage into early adulthood: ratios of observed to expected ill health for four of the five indices examined at age 23 were all significantly below one (self rated health 0.81, asthma and/or wheezy bronchitis 0.63, allergies 0.79, emotional health 0.75). Children with more morbidity at age 7 had higher ratios of ill health in adulthood. A chronic condition in childhood was associated not only with excess morbidity in the short term but also with a poor health rating in early adult life (ratio = 1.38). Morbidity was significantly increased for most of the adulthood indices among children with asthma and/or wheezy bronchitis. However most ill health in young adulthood occurred in study members with a relatively healthy childhood. CONCLUSIONS: Although the state of health in childhood has long term implications, it does not form a substantial contribution to ill health in early adult life.

Cerebral palsy in two national cohort studies.

The prevalence of cerebral palsy in the 1958 British Perinatal Mortality Survey and the 1970 British Births Survey remained constant at 2.5/1000 births (40 and 41 cases, respectively). The prevalence at 10 years was higher in the 1970 cohort in which all children with cerebral palsy survived, whereas 22% of the cases in the 1958 cohort died during the first 10 years of life. A case-control study matched three controls for social class, maternal age, parity and marital state, and a further three controls for the infant's sex, gestation, and birth weight. Comparison of cases and controls showed no consistent differences in social and environmental factors, history of pregnancy, labour, or delivery. Important differences were found in the incidence of respiratory and neurological symptoms in the neonatal period. These prospective data derived form two whole populations of births support the hypothesis that most cases of cerebral palsy are not associated with adverse obstetric factors, and confirm that neonatal neurological symptoms are associated with subsequent cerebral palsy.

Asthma as a link between chest illness in childhood and chronic cough and phlegm in young adults.

The link between chest illnesses in childhood to age 7 and the prevalence of cough and phlegm in the winter reported at age 23 was investigated in a cohort of 10,557 British children born in one week in 1958 (national child development study). Both pneumonia and asthma or wheezy bronchitis to age 7 were associated with a significant excess in the prevalence of chronic cough and phlegm at age 23 after controlling for current smoking. This excess was largely attributable to the association of cough and phlegm at age 23 with a history of asthma or wheezy bronchitis from age 16. When adjustment was made for recent wheezing, current cigarette consumption, previous smoking habit, and passive exposure to smoke the relative odds of cough or phlegm, or both, in subjects with a history of childhood chest illness was 1.11 (95% confidence interval 0.97 to 1.27). When analysed separately asthma, wheezy bronchitis, and pneumonia up to age 7 did not significantly increase the prevalence of either cough or phlegm. The explanation for the observed continuity between chest illness in childhood and respiratory symptoms in later life may lie more in the time course of functional disturbances related to asthma than in the persistence of structural lung damage.

Infection of the fetus and the newborn: prevention, treatment and related handicap.

Congenital infection is uncommon and the cause of only a small proportion of handicap seen in children but some infections may be preventable or even treatable. As an example, the congenital rubella syndrome first described in the 1940s is preventable by use of the vaccine but cases still occur. It is hoped that with the introduction of the measles, mumps, rubella immunization for young children, rubella will become as rare in the UK as it is in the USA. Cytomegalovirus is now a more common cause of handicap than rubella but no vaccine has been developed. Although antiviral drugs are available for herpes simplex virus and vaccinia, infection mortality in the newborn is high, even following the use of these agents; many HSV infections in the newborn arise following primary and asymptomatic maternal infections so that treatment may start late in the course of the illness. The obstetrician needs to understand the natural history as well as possible investigations available for congenital infections. There may be warning signs which require action, such as herpetic lesions in the genital tract of the mother. Less specific abnormalities during pregnancy, such as intra-uterine growth retardation and spontaneous onset of preterm labour, may point to congenital infection. This chapter describes both antenatal and postnatal management of the major congenital infections. We have included recent research data that should influence clinical practice; studies on HSV which suggest that, for women with a history of recurrent infection, routine viral culture of the genital tract at the end of pregnancy is unnecessary; reports from both the USA and the UK that rubella immunization performed inadvertently during early pregnancy has not resulted in the congenital rubella syndrome. The chapter would not have been complete without a discussion of human immunodeficiency virus, of concern to the obstetrician and midwife. There is still much to be learned about the natural history of this infection in both the mother and infant.

The natural history of asthma in childhood.

The incidence and prognosis of childhood asthma and wheezing illness (AW) was studied using data obtained at ages 7, 11, and 16 from a national cohort of 8806 children born in 1958. By the age of 16, 24.7% were reported to have experienced at least one episode of AW. In 18.3% AW had started before the age of 8, but only 4.2% continued to have symptoms in later childhood. A further 3.6% began to have AW between the ages of 8 and 11, and 2.8% began between the ages of 12 and 16. Of those with AW at age 7, 28.3% had symptoms at 11 and 16.5% at 16; these proportions were about doubled if AW at 7 had been severe. The associations between natural history and a large number of perinatal, social, environmental, and medical factors were examined. Those which predicted the onset of AW after the age of 7 were: male sex of child; mother aged 15-19 at child's birth; history of pneumonia, whooping cough, throat or ear infections or tonsillectomy; eczema, allergic rhinitis; and periodic vomiting or abdominal pain.

A national study of asthma in childhood.

A history of asthma was obtained in 3.5% of a representative national sample of children aged 11 years. A further 8.8% had a history of wheezy bronchitis. In the 12 months before the interview, 2% had experienced attacks of asthma and a further 2.9% attacks of wheezy bronchitis. Both conditions were significantly more common among boys than girls, and a history of asthma was reported more frequently among children from non-manual than from manual social classes. Children with frequent attacks of wheezing had lower mean relative weights. A history of eczema and hay fever was more frequently discovered in children with reported asthma than in those with wheezy bronchitis, whereas migraine or recurrent headaches, recurrent abdominal pain, and recurrent throat or ear infections were more commonly associated with wheezy bronchitis than with asthma. The modified Rutter home behaviour scale, which reflects the parental view of the child's behaviour, was significantly raised among children with a history of wheezing, but their school behaviour as judged by the Bristol social adjustment guide showed no such difference. In spite of increased absence from school because of illness, no differences were found in educational attainment between children with a history of asthma or wheezy bronchitis and those with neither condition.
