PIP: A nonrepresentative sample of 207 women aged 15-35 living in the city of Tijuana were surveyed in 1985 to determine attitudes toward maternal and child health in a Mexican border city. The women were stratified by neighborhood of residence and housing type. 65 were classified in the upper, 80 in the middle, and 62 in the lower socioeconomic strata. 60% of the women surveyed had migrated to Tijuana. They represented 22 Mexican states of origin, not counting other parts of Baja California. 80% lived in extended families and the average household size was 5 persons. 56.5% were married. 51 were economically active, with proportionately more upper status women employed. The average educational level was 8.8 years. 21.5% were students at the time of the survey. 6.3% of the births to upper stratum women, 8.2% to middle stratum women, and none to lower stratum women occurred in the US. 72.3% of upper stratum women, 82.5% of middle stratum women, and 88.7% of lower stratum women stated they preferred birth to occur in Mexico. 27.7% of upper stratum, 17.5% of middle stratum, and 9.7% of lower stratum women would prefer to give birth in the US. The reason most commonly given for preferring birth in the US was superior medical attention. 80% of the births in Mexico were in private hospitals and the rest in public. The upper stratum women had the most prenatal visits and the smallest families. 20% of the middle and lower strata women who had ever been pregnant received no prenatal care. Middle and lower strata women were less informed about the importance of prenatal care. Traditional beliefs about pregnancy and the perinatal period were strongest among middle stratum women. Upper status women were the most likely to enter the US for short visits. 1/3 of middle status women and 70% of lower status women reported they never entered the US, primarily because they lacked documents. Lower stratum women tended to seek medical care late in pregnancy. Home remedies and the advice of relatives and neighbors constitute an option for prenatal care for these impoverished women. The tradition of breast feeding on demand is apparently being lost among women in Tijuana. 34% of the mothers declared they had never breast fed a child, and most of the rest discontinued breast feeding after a very short time. 53% of the 187 women who reported they were sexually active did not use contraception. 19% used oral contraceptives, 14% used IUDs, and 5% were sterilized. Although study results showed that socioeconomic status was related to the use of prenatal and obstetric services, there were no significant differences among socioeconomic groups in infant feeding or family planning practices.^ieng
