passive smoking (ps), a well-known health risk, is the major source of indoor pollution. there is some inconsistent evidence that ps during pregnancy may increase the risk of low birth weight. the aim of the present study was to determine the effects of ps exposure during pregnancy on weight, length and cranial circumference at birth of babies born to women who have described themselves as nons...

BACKGROUND The association between birthweight and asthma, eczema and rhinoconjunctivitisis conflicting. AIMS To examine the association between birthweight and symptoms of asthma, eczema and rhinoconjunctivitis. METHODS Parents or guardians of children aged 6–7 yr completed written questionnaires about symptoms of asthma, rhinoconjunctivitis and eczema, and several risk factors, including ...

OBJECTIVE To assess the relationship between housing conditions and low birthweight and preterm low birthweight among low-income women. METHODS A case-control study was conducted with post-partum women living in the city of Rio de Janeiro, Southeast Brazil, in 2003-2005. Two groups of cases, low birthweight (n=96) and preterm low birthweight infants (n=68), were compared against normal weight...

This study examines the spatial patterns and socioeconomic correlates of low weight births (infants who weigh less than 2500 grams at birth) in Kamloops, BC between 1990 and 1995. “Natural” zones of low birthweight risk were identified by interpolating geocoded birth data to create a continuous surface map of low birthweight values. The zones were used in turn used to aggregate birth and socioe...

Low birthweight Low birthweight (less than 2,500 grams) has been identified as an important factor impacting on child survival and can affect perinatal mortality, infant mortality, and development of chronic diseases in later life. Preterm birth (<37 weeks) or restricted foetal growth can result in a low birthweight birth. Accordingly, a key performance indicator measuring the incidence of low ...

Globally an estimated 20 million infants are born with low birthweight (LBW), of those over 18 million are born in developing countries. These LBW infants are at a disproportionately higher risk of mortality, morbidity, poor growth, impaired psychomotor and cognitive development as immediate outcomes, and are also disadvantaged as adults due to their greater susceptibility to type 2 diabetes, h...

Thyroxine (T4) screening values in infants of low birthweight in relation to birthweight and gestational age are reported. There were 86 healthy infants of low birthweight (group 1), and 29 preterm infants with respiratory distress syndrome (group 2). All the group 2 infants and 36% of those in group 1 had a T4 screening value below the cut-off point (-2.1 SD). In group 1 there was a significan...
