This paper analyzes the relationship between the adoption of female sterilization and 3 social and modernization variables (education, income, and family type) and 2 demographic variables (number of living children and years of marriage) for a sample of 200. The influence of each of these 5 variables on female sterilization is studied by the percentage distribution method and the variance test. The data are analyzed by using the urban-rural and adopter-nonadopter classification. Results show that the social and modernization variables do not seem to influence the adoption of female sterilization among urban or rural households, but the demographic variables--number of living children and years of marriage--do seem to have a clear influence. Among rural households there are differences in these variables between adopters and nonadopters of female sterilization. There is a policy implication here: the government has to advocate the 2 child norm to all eligible couples in the early years of marriage and advise them to adopt sterilization after the birth of the 2nd child. This will go a long way in achieving the national target of the replacement level of reproduction by the year 2000.

In order to learn the natural expectancy period of first pregnancy as well as the influences of some biosocial variables, a clinical-retrospective study was performed within 1120 gravida I women. All of them attended the major institutes of health care in Mexico City (IMSS, ISSSTE, SS and DDF). Data were obtained by means of predetermined questions from subjects after the first postpartum hours. None of them had previously used any contraceptive method. Results showed age at the first pregnancy: 21.6 +/- 3.8 (years); gestational interval 22.1 +/- 19.9 (months) and a 67% achievement rate the following twelve months of sexual activity. Eutocia was seen in 54% of these population and significant linear correlation was attained between age of the patient and the gestational interval. It seems that this is the first information regarding the fertility critical period within our society.
This report is based on a survey conducted in 1986-87 of sexually active adult male residents in a low-income community of Port-au-Prince, Haiti. The objectives were to investigate knowledge of and attitudes toward condoms; to evaluate the effectiveness of the existing condom distribution program; and to obtain information that can be used in the design of strategies to increase condom acceptance and use among men throughout Haiti. A final sample of 706 sexually active adult male residents in stable unions, including a specially drawn sample of male partners of condom acceptors, were interviewed in their homes. Although condoms are almost universally known, they are rarely used. The majority felt that the responsibility for family planning should be borne by the woman. Whereas condoms may be of limited popularity for family planning purposes in Haiti, it should be determined whether they might be more acceptable as an effective means of controlling the spread of AIDS and other STDs.
Adolescent pregnancy, often unplanned and unwanted, has a negative impact on the physical, emotional, educational, and economic condition of the pregnant teenager. Forty percent of the one million adolescents who became pregnant in 1986 chose abortion, and, of the remainder, 61% were unmarried. Teenage mothers in greater numbers and at younger ages are opting to keep and raise their children. In 1987 over $19 billion in federal monies were expended on families begun when the mother was a teenager. The preferred approach to this problem is prevention of teenage pregnancy rather than abortion, with emphasis on sex education and access to family planning information and contraceptive devices for both females and males. Sex education in schools is presented in widely varying formats; in fact, prevention of pregnancy may not even be presented. Family planning clinics are subject to the whims and biases of the funding agencies. Clinicians have an important role in providing guidance for teenage patients and their parents, but can also influence school and community leadership to ensure that all teenagers receive sound sex education in school programs and that family planning agencies are permitted to counsel teenagers and provide contraceptive devices.
Simulation models were used to compare the health consequences of birth control methods currently relied on by American women with those of using no method. The incidence of morbidity and mortality related to unintended pregnancies, live births, abortions, upper genital tract infections, tubal infertility, cardiovascular disease and reproductive cancers were estimated for hypothetical cohorts of 100,000 women aged 15-44. Women who never use any method and who never have an abortion would have an average of 18 births during their reproductive lifetime, compared with no more than five among women using any of the available birth control methods. Consequently, use of any method prevents more deaths from pregnancy and childbirth than are associated with method use. The proportion of women who would become infertile--estimated by taking into account the likelihood of developing upper genital tract infections and the probability that any pregnancies that occurred would be ectopic--is reduced substantially if women at low risk of sexually transmitted diseases use any method and if women at high risk use oral contraceptives or barrier and spermicide methods. Oral contraceptive use has a relatively small, independent effect on the risk of cardiovascular diseases, but it greatly augments that risk in combination with smoking and increased age. When ovarian, endometrial and breast cancers are considered together, there will be approximately 110 fewer diagnoses of these three cancers per 100,000 ever-users of the pill aged 15-54 than among 100,000 never-users; furthermore, prior to age 45, 100,000 ever-users will experience 10 fewer deaths from ovarian or endometrial cancers than never-users of the pill.(ABSTRACT TRUNCATED AT 250 WORDS)
This report provides an update of the authors' previous estimates of first-year probabilities of contraceptive failure for all methods of contraception. Estimates are provided of failure during typical use (which includes both incorrect and inconsistent use) and during perfect use (correct use at every act of intercourse). The difference between these two probabilities provides a measure of how forgiving of imperfect use each method is. These revisions are prompted by recent studies that provide the first estimates of failure during perfect use for periodic abstinence and the cervical cap, by more complete evaluations of implants, and by the appearance of the Copper T 380A and disappearance of other IUDs from the US market. Also provided is a more complete explanation of how the previous estimate of the probability of becoming pregnant while relying solely on chance should be interpreted, and this estimate is revised slightly downward.

The results of a two-year longitudinal study of the effect that development program incentives have upon family planning in Northeastern Thailand are presented. These incentives, implemented by the Population and Community Development Association, Thailand, included animal raising and agricultural, home industry, and environmental activities. An experimental design including baseline and follow-up surveys supplemented by a continuous monitoring system was utilized to test hypotheses on the family planning impacts of the incentives. Findings indicate that the incentives contributed significantly to the maintenance of high levels of family planning practice through the program period 1982-1984.
In 1983, one-quarter of married Guatemalan women aged 15-44 years were using contraception, and female sterilization was the most prevalent method. Fertility rates for the population were at correspondingly high levels, with an overall total fertility rate of about six births per woman. Contraceptive prevalence varied by residence and ethnic group; less than 5 percent of currently married Indian women and about 50 percent of married women in the capital city area were using contraception. From 1978 to 1983, prevalence increased overall by six percentage points, with surgical contraception accounting for most of the increase. Findings of the study suggest that different strategies need to be employed among Ladino and Indian women in order to increase contraceptive prevalence in these subgroups.
