Just after exclusions, data from kids (mean (SD) . years, boys) on test occasions had been incorporated (hereafter known as the reference population; Figure). Sex and age had been distributed similarly across the ethnic groups (Table ; OLS,Table E). On average, of children were born preterm (wks gestation) and had been low birthweight (.kg), the latter disproportionately SouthAsian. Prior wheeze and existing symptoms had been relatively uncommon (and respectively), although of Othermixed ethnicity children reported previous asthma. According to parental report, of young children years of age had began puberty. Ethnic differences in body physique Adjusted for age and sex, BlackAfrican origin young children have been significantly heavier and taller with longer legs than children from other ethnic groups (Table , Table E). Adjusted for sex, age and height, chest circumference was significantly bigger and ratio of chest depth width considerably larger in BlackAfrican origin than White youngsters, but chest region did not differ. Compared with White young children, following adjusting for sex, age and height, fatfree mass was on average larger in BlackAfrican origin children (difference CI:. kg.;.), lower in SouthAsians (. kg.;.) and similar in these of Othermixed ethnicity. Ethnic variations in SEC and tobacco smoke exposure General, of youngsters have been receiving absolutely free school meals, with BlackAfrican origin young children representing the highest proportion (Table). Similarly, relatively a lot more BlackAfrican origin children scored low on FAS and IMD (Tables and E). White and other ethnicity young children skilled most smoke exposure (Table). Salivary cotinine levels were .ngmL in . of youngsters with no reported household smoking, whereas for cotinine levels .ngml (range ..ngmL indicative of passive smoke exposure) reported household smoking. Cotinine levels (.ngmL) indicative of active smoking had been only observed in a single .yearold from a reportedly nonsmoking household.
