RESUMO
Preventive measures for teenage pregnancy (TP), would decrease infant mortality early undernutrition and statal social expenditure. The cost of programs for TP would decrease with a sensitive risk indicator. We searched some pysoshocial and familial parameters, useful to built up this indicator. Self steem (Piers-Harris est), intrafamilial realtionship (Familial Apgar of Magdaleno) and the use of break time were studied in 60 pregnant teenagers (PT), 60 non pregnant teenagers at a low risk of pregnancy (LRP) and 60 non pregnant teenagers at a high risk of pregnancy (HRP). PT and HRP showed lower self steem than LRP (88,3, 70,0 Y 41,6 per cent respectivelly, under 7 points) lower familial apgar (61.6, 50 y 8.3 under score 6) and lower the quality of use of break time (66.7, 74.1 and 31.7 per cent respectivilly with regular or deficient quality). The self steem intrafamilial relationship hand use of break time were associated to early pregnancy and high risk of pregnancy. These parameters are import to built up a sensitive risk indicator of early pregnancy in order to decrease the prevalence of this serious problem
