RESUMO
AIMS: To examine the effects of the home environment on unintentional domestic injuries and related health care attendance in infants from deprived families. METHODS: Ten mechanisms that caused unintentional domestic injury during the first year were investigated in a population-based study of 1-year-old children in southern Brazil. Odds ratios of injury-related health care attendance were estimated by number of injury mechanisms reported. Variation in number of mechanisms (in the whole sample) and odds ratios of care attendance (in children with reported injuries) were estimated for socioeconomic and psychosocial variables. RESULTS: Among all children (394) 86% had injuries; 10.9% care attendance and 0.5% hospitalisation were reported, and 14.5% presented dental trauma. Injury-related care attendance increased with the number of injury mechanisms (linear trend OR = 1.34, 95% CI = 1.09-1.66). In multivariable linear regression, injury mechanisms increased with the number of home hazards (p = 0.047) and decreased with duration of exclusive breastfeeding (p = 0.039), maternal involvement-responsiveness (p = 0.037) and mother's paid work (p = 0.018). Injury-related health care attendance among children with reported injuries was positively associated with maternal involvement-responsiveness (OR = 2.27, 95% CI = 1.11-4.67) and home organization (OR = 2.25, 95% CI = 1.09-4.65). CONCLUSION: Injury control can benefit from policy and practice that improve housing, reduce home hazards and promote breastfeeding, maternal bonds, safety practices and injury care.

A method for translating research data from the Denver Test into individual scores of developmental status measured in a continuous scale is presented. It was devised using the Denver Developmental Screening Test (DDST) but can be used for Denver II. The DDST was applied in a community-based survey of 3389 under-5-year-olds in Porto Alegre, Brazil. The items of success were standardised by logistic regression on log chronological age. Each child's ability age was then estimated by maximum likelihood as the age in this reference population corresponding to the child's success and failures in the test. The score of developmental status is the natural logarithm of this ability age divided by chronological age and thus measures the delay or advance in the child's ability age compared with chronological age. This method estimates development status using both difficulty and discriminating power of each item in the reference population, an advantage over scores based on total number of items correctly performed or failed, which depend on difficulty only. The score corresponds with maternal opinion of child developmental status and with the 3-category scale of the DDST. It shows good construct validity, indicated by symmetrical and homogeneous variability from 3 months upwards, and reasonable results in describing gender differences in development by age, the mean score increasing with socio-economic conditions and diminishing among low-birthweight children. If a standardised measure of development status (z-scores) is required, this can be obtained by dividing the score by its standard deviation. Concurrent and discriminant validity of the score must be examined in further studies.

AIMS AND METHODS: Concurrent validity of maternal opinion of child development was estimated in a cross-sectional, population-based survey of 6-59-mo children (n=3025), using a standard measure devised from the Denver Developmental Screening Test. RESULTS: Sensitivity, specificity and negative predictive value increased with maternal education and family income. Positive predictive value was higher in low-income families and children with impairments, low birthweight and long hospital stays. CONCLUSION: Children at social and clinical risk should be assessed more carefully, even if maternal report is normal or advanced.
