20世纪50年代，波多黎各开始了积极的工业化计划。我们使用1982年波多黎各生育和计划生育评估的数据来描述波多黎各母乳喂养发生率随时间的趋势，并确定其一些决定因素。从1946年到1982年，5884名婴儿出生在这个具有统计代表性的育龄妇女样本中。1960年以前出生的婴儿接受过母乳喂养的比例为59%（平均持续时间为7.8个月），1970年至1974年出生的婴儿接受过母乳喂养的比例降至26%（平均持续时间为4.9个月），1980年至1982年出生的婴儿接受过母乳喂养的比例上升至38%（平均持续时间为3.4个月）。先前的母乳喂养经验是母乳喂养新生儿的重要决定因素。与以前没有母乳喂养的母亲所生的婴儿相比，曾经母乳喂养过的母亲所生的婴儿接受母乳喂养的可能性要高7.3倍（95%可信区间= 6.6,8.0）。20世纪80年代初，波多黎各母乳喂养婴儿的比例为38%，低于拉丁美洲的74%至97%，也低于美国同期的54%。该研究为未来的干预策略提供了基线数据。
In the 1950s, Puerto Rico began an active industrialization program. We used data from the 1982 Puerto Rico Fertility and Family Planning Assessment to describe the trend in the incidence of breastfeeding in Puerto Rico over time and to ascertain some of its determinants. From 1946 through 1982, 5,884 infants were born among this statistically representative sample of reproductive-aged women. The proportion of infants who had ever been breastfed was 59 percent for births before 1960 (mean duration = 7.8 months), dropped to 26 percent for infants born from 1970 to 1974 (mean duration = 4.9), and rose to 38 percent for births delivered from 1980 to 1982 (mean duration = 3.4). Prior breastfeeding experience was an important determinant of breastfeeding a newborn. Infants of mothers who had breasfed a previous baby were 7.3 times more likely to be breastfed (95% condidence interval = 6.6, 8.0) compared with infants of mother who had not previously breastfed. The 38 percent of infants who were breastfed in Puerto Rico in the early 1980s is below the 74 percent to 97 percent reported in Latin America and below the 54 percent reported in the United States for the same period. This study provides baseline data for any future intervention strategies.
