to analyze the changes in prevalence, median duration and correlates of breastfeeding in a small city in São Paulo state, Brazil.
analysis of two cross-sectional studies, conducted at intervals of one decade, with 261 and 302 children younger than two years, respectively. We used Kaplan-Meier survival analysis for calculation of the median duration of breastfeeding, and Cox regression for correlates analysis, with significance level of 5%.
an increase of 33.4% in the prevalence of exclusive breastfeeding and 20.9% in breastfeeding was identified. Regarding the latter, the median duration increased from 7.2 to 12 months. In the most recent study, the median duration was lower in first-born children who used pacifiers, and it was not associated with breastfeeding incentive actions.
advances in the prevalence and duration of breastfeeding were observed during the 10 year-period, however, pacifier use still remains associated to a shorter median duration of breastfeeding. Our findings contribute to highlighting the need for intensification of nursing actions in the promotion of breastfeeding, and discouragement regarding the use of pacifiers.
分析巴西圣保罗州一个小城市母乳喂养的患病率、中位持续时间及相关因素的变化。
对两项横断面研究进行分析，这两项研究每隔十年开展一次，分别涉及261名和302名两岁以下儿童。我们采用Kaplan-Meier生存分析来计算母乳喂养的中位持续时间，并采用Cox回归进行相关因素分析，显著性水平为5%。
纯母乳喂养的患病率增加了33.4%，母乳喂养的患病率增加了20.9%。就后者而言，中位持续时间从7.2个月增加到了12个月。在最近的研究中，使用安抚奶嘴的头胎儿童的中位持续时间较短，且其与母乳喂养激励措施无关。
在这10年期间，母乳喂养的患病率和持续时间有所提高，然而，使用安抚奶嘴仍然与较短的母乳喂养中位持续时间相关。我们的研究结果有助于强调加强促进母乳喂养护理措施的必要性，并劝阻使用安抚奶嘴。
