Motor and adaptive development were studied longitudinally at 4, 8, 12, and 18 mo. in Brazilian infants of low and middle socioeconomic status. No significant differences were found between these two groups. Gesell Developmental Quotients were similar to those found in American infants, which did not confirm precocious motor development in Brazilian infants.
In a sample of 245 Brazilian infants, the effects of intrauterine growth and gestational age upon psychomotor development were studied through ages 4 to 18 mo. Gestational age was more important than intrauterine growth in determining psychomotor development in the first 18 mo. of life. Intrauterine growth had a significant but smaller and more stable effect than gestational age upon psychomotor development at all ages. Maternal parity, interval between the birth of the child studied and the next oldest sibling, 5-min. Apgar score, and socioeconomic status were also relevant to psychomotor development at these early ages.
This study reports of a further analysis on the data presented in a previous work. The intention of the present study was to analyse exhaustively the relationship between some social and demographic variables with some aspects of attempts to suicide. The variables for this study were chosen on the basis of the completeness of data. Sex, age, single vs. married, and family relationship of the subjects were the predictive variables; the aspects of attempts to suicide considered were: number, kinds, means, and motives of attempts. An analysis of canonical correlation failed to show clearly any common relationship of the demographic variables in regard to the aspects of attempts to suicide. In fact, the first group of covariates resulted in a correlation of .40 whose chi square was 22.16 for a p less than .10. However, an univariate analysis of multiple regression for each of the four aspects of attempts to suicide over the four demographic variables showed that a) age of subjects has a definite relationship with the motives to commit suicide, that is, with age; the motives to attempt suicide change predominantly from family difficulties to problems of a more social and professional character; b) also, it was observed a generalized tendency on the part of male subjects to show attempts to suicide of a more serious nature, namely, they plan their attempts and make use of means of a more lethal nature (poison instead of simple drugs). However, it must be noted that the male sample was older than the female, making it hard to decide in this case whether age or sex of the subjects would be the best predictor.
