The contraceptive prevalence rate increased from 23% in 1965 to 58% in 1975 and 66% in 1984. Duration of breast-feeding was stable during the 1960s, decreased in the early 1970s, and increased after about 1976. Fecundability among women who did not practise contraception was lower than expected and declined between 1960 and 1975, probably because of selection effects. Despite a high consistency between estimations from the reproductive histories and other sources of data, some suggestion of omissions of short periods of contraceptive use in the distant past was detected. The survey may have reduced recall errors by using a calendar that summarizes major life events together. The analysis demonstrated the feasibility and usefulness of asking for lifetime reproductive histories in fertility surveys in developing countries.<\/jats:p>","DOI":"10.1017\/s0021932000018150","type":"journal-article","created":{"date-parts":[[2008,7,31]],"date-time":"2008-07-31T08:05:24Z","timestamp":1217491524000},"page":"419-432","source":"Crossref","is-referenced-by-count":4,"title":["Fertility change in Costa Rica 1960\u201384: analysis of retrospective lifetime reproductive histories"],"prefix":"10.1017","volume":"21","author":[{"given":"Luis","family":"Rosero-Bixby","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark W.","family":"Oberle","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2008,7,31]]},"reference":[{"key":"S0021932000018150_ref011","first-page":"79","article-title":"Determinantes de la fecundidad costarricense","volume":"32","author":"Rosero-Bixby","year":"1983","journal-title":"Notas de Poblacion"},{"key":"S0021932000018150_ref009","doi-asserted-by":"publisher","DOI":"10.1080\/19485565.1969.9987796"},{"key":"S0021932000018150_ref010","volume-title":"Fecundidad y Anticonception en Costa Rica 1981: Resultados de la Segunda Encuesta de Prevalencia Anticonceptiva","author":"Rosero-Bixby","year":"1981"},{"key":"S0021932000018150_ref013","volume-title":"Determinantes de la Fecundidad en Costa Rica: Analisis Longitudinal de Tres Encuestas","author":"Rosero-Bixby","year":"1982"},{"key":"S0021932000018150_ref007","first-page":"1247","article-title":"A casecontrol study of breast cancer and hormonal contraception in Costa Rica","volume":"79","author":"Lee","year":"1987","journal-title":"J. natn.
