Breast cancer risk and oral contraceptive use: results from a large case-control study.

The association between oral contraceptive use and breast cancer risk was examined using data from a case-control study of breast cancer in Long Island, New York. Cases were defined as female residents of Nassau and Suffolk Counties between the ages of 20 and 79, diagnosed with breast cancer between January 1, 1984 and December 31, 1986. Age- and county-matched controls were selected from driver's license files. Among all women under age 70 at diagnosis, there was no association between oral contraceptive use and breast cancer; there was, however, a positive association in the subgroup ages 20-49 (adjusted odds ratio = 1.68, 95% CI: 1.16-2.42). Risk increased with increasing duration of use, but did not differ between women who first used oral contraceptives before the first pregnancy and those who first used them later, or between women who first used oral contraceptives before age 25 and those who first used them at a later age. Risk also appeared to increase with number of years of use before the first pregnancy or before age 25, although numbers were small. History of benign breast disease did not influence risk. The association of breast cancer risk with oral contraceptive use appeared stronger in women from Suffolk County than Nassau County.

Reasons for non-use of family planning methods at Ilorin, Nigeria: male opposition and fear of methods.

This study reports the main reasons given for non-use of contraception by non-pregnant women aged 15-44 years, who are at risk of unplanned pregnancy and living in the Ilorin Local Government Area of Kwara State, Nigeria. Six hundred and forty-six women were derived from a stratified cluster sample and interviewed using a questionnaire. Almost one-third (31.4%) of respondents gave male opposition to family planning as the reason for current non-use. Another 13.3% expressed fear of methods, 6.3% did not want to use contraception until the first child was born, and 13.6% until the desired number of children were born. Sociodemographic variables including age, educational level, religion, and residence as reasons for non-use were reported. Other important findings included a high awareness of, low availability of, or poor accessibility to contraceptive methods. Short and long term intervention strategies using information, education and communication materials are proposed to combat low levels of contraceptive use in this area.

Utilization of health services by Mexican immigrant women in San Diego.

The limited empirical data available on maternal health problems among Mexican immigrant women in the United States suggest that they underutilize health services, especially general preventive care. Research conducted among legal and undocumented women in the Mexican immigrant population in San Diego, California, support these findings. Among undocumented mothers, 11.5% of their births in the U.S. occurred with no prenatal care or care sought in the third trimester, which is much higher than Mexican women legally in the country (3.6%) and the general San Diego maternal population (3.8%). When we examine births which occurred within the last five years by immigration status, we find that women legally in the country have a much higher rate of cesarean delivery of both undocumented women and women in the general San Diego maternal population. Undocumented women in our sample were much less likely than their legal counterparts to return for postpartum examinations for themselves, to seek neonatal care for their infants, and to have had Pap examinations or carry out breast self-examinations.
