This project will investigate the socioeconomic, demographic, and community, influences on infant feeding patterns and trends in Indonesia. Virtually all Indonesian infants are breastfed, and they are among the latest in the world to be weaned. Over the last three decades, the trend in Indonesia has been toward even longer durations of breastfeeding. However, Indonesian mothers tend to include other liquids or food in the infant's diet relatively early in the child's life, foregoing the potentially life-saving benefits of unsupplemented breastfeeding (which isolates infants from the bacterial pathogens that cause diseases of the digestive tract). The conceptual model guiding the research views infant feeding patterns as the result of decisions parents make based on their perceptions of the costs and benefits of unsupplemented and supplemented breastfeeding vis-a- vis other modes of feeding. These decisions are constrained by resources, institutions, cultural norms, and underlying physiological mechanisms. This framework yields as a number of hypotheses about influences on the incidence and duration of unsupplemented and supplemented breastfeeding, which will be tested using new retrospective data, from the Indonesian Family Life Survey (IFLS), on a large number of mothers and on each of their children. Systems of duration and limited-dependent-variable models will be used to investigate determinants of the decision to initiate breastfeeding, the duration of total breastfeeding, and the timing of supplementation. The analyses will allow the influences on infant feeding decisions to vary over the course of infancy and will recognize the sequential and correlated nature of decisions for different children in the same family. Explanatory variables include prices of water and sanitation, medical are, infant foods, and contraceptives; women's value of time; household resources; and the information available about the health and contraceptive effects of breastfeeding. Influences on the initiation and duration of breastfeeding in Indonesia will be compared with those in Malaysia, which has one of the shortest durations of breastfeeding among developing countries. The Malaysian analysis will use data from the First and Second Malaysian Family Life Surveys (MFLS-1 and MFLS-2). The MFLS data will also be used to evaluate the quality of long-term recall about infant feeding, by comparing MFLS-2 reports (in 1988) about births in 1976 and earlier to MFLS-1 reports (in 1976) about those same births.

该项目将调查社会经济、人口和 社区，对印度尼西亚婴儿喂养模式和趋势的影响。 几乎所有印度尼西亚婴儿都接受母乳喂养，他们属于 世界上最晚断奶的。 近三十年来的趋势 在印度尼西亚，母乳喂养的时间甚至更长。 然而，印尼妈妈们倾向于在食物中加入其他液体或食物。 婴儿的饮食在孩子生命的相对早期阶段就已被忽视 无补充母乳喂养可能具有挽救生命的益处（ 将婴儿与引起疾病的细菌病原体隔离 消化道）。 指导研究的概念模型将婴儿喂养模式视为 父母根据自己的看法做出决定的结果 不补充和补充母乳喂养的成本和好处 与其他喂养方式相比。 这些决定受到资源的限制， 制度、文化规范和潜在的生理机制。 这个框架产生了一些关于影响的假设 未补充和补充母乳喂养的发生率和持续时间， 将使用来自印度尼西亚的新回顾性数据进行测试 家庭生活调查 (IFLS)，针对大量母亲和每位母亲 他们的孩子。 持续时间系统和有限因变量模型将用于 调查决定开始母乳喂养的决定因素 总母乳喂养的持续时间和补充的时间。 这 分析将使婴儿喂养决策的影响因人而异 婴儿期的过程并会识别顺序和相关性 同一家庭中不同孩子的决定的性质。 解释性的 变量包括水和卫生设施、医疗、婴儿的价格 食品和避孕药具；女性的时间价值；家庭资源；和 有关健康和避孕效果的现有信息 哺乳。 对印度尼西亚母乳喂养开始时间和持续时间的影响 将与马来西亚进行比较，马来西亚是最短的国家之一 发展中国家母乳喂养的持续时间。 马来西亚人 分析将使用第一和第二马来西亚家庭生活的数据 调查（MFLS-1 和 MFLS-2）。 MFLS 数据还将用于评估 通过比较 MFLS-2，了解有关婴儿喂养的长期记忆的质量 向 MFLS-1 报告（1988 年）有关 1976 年及之前的出生情况的报告（在 1976）关于同样的出生。
