The study aimed to discuss the consistency of estimates of maternal breastfeeding in the Brazilian National Health Survey (PNS) and the implications for the analysis of trends in these indicators from 1986 to 2013. The main limitation for the current estimate (2013) of breastfeeding indicators based on the PNS and their trend (1986-2013) is the absence of the interview date in the microdata, thus hindering a precise calculation of age. Previous studies have shown different scenarios for exclusive breastfeeding based on the PNS: 36.6% (stabilization of prevalence in comparison to 2006 [Brazilian National Survey of Demography and Health - PNDS]) and 20.3% (downward prevalence). Simulations of the interview date using the date of data collection in the PNS (August 2013 to February 2014) indicated a variation of prevalence 25.3% to 42.8% (exclusive breastfeeding); 54% to 61.5% (breastfeeding); and 32.7% to 40.5% (breastfeeding, second), respectively. The discrepancy in the scenario for breastfeeding status calls attention to the unfeasibility of the exclusive breastfeeding estimate for 2013, pending clarification of the interview date.
该研究旨在探讨巴西国家卫生调查（PNS）中关于母亲母乳喂养情况估计的一致性，以及对分析1986年至2013年这些指标趋势的影响。基于PNS对当前（2013年）母乳喂养指标及其趋势（1986 - 2013年）进行估计的主要限制在于微观数据中缺少访谈日期，从而妨碍了对年龄的精确计算。以往的研究基于PNS展示了不同的纯母乳喂养情况：36.6%（与2006年[巴西国家人口与健康调查 - PNDS]相比患病率稳定）以及20.3%（患病率下降）。利用PNS中数据收集日期（2013年8月至2014年2月）对访谈日期进行模拟，结果表明纯母乳喂养患病率的变化分别为25.3%至42.8%；母乳喂养患病率为54%至61.5%；二次母乳喂养患病率为32.7%至40.5%。母乳喂养状况情况的差异凸显了在明确访谈日期之前对2013年纯母乳喂养估计的不可行性。
