We examine the relationships between climatic conditions, breastfeeding behavior, and maternal time use in Ethiopia. Infant feeding practices are important predictors of child nutrition that may be affected by a number of factors including mother's time engaging in agricultural labor, food security, cultural beliefs, and antenatal care. We use panel data from the Living Standards Measurement Study to investigate linkages between climatic conditions during a child's first year of life and year prior to birth and duration of exclusive breastfeeding. We then explore one potential mechanism: women's agricultural labor. Results indicate that rainfall during the primary agricultural season-kiremt-in a child's first year of life plays an important role in duration of exclusive breastfeeding. Experiencing 25 cm of average monthly kiremt rainfall, versus 5 cm, is associated with a 20-percentage-point decrease in the likelihood of being exclusively breastfed for the recommended six months. More kiremt rainfall is associated with a greater number of days that women spend planting and harvesting, and at high levels of rainfall women with infants do not engage in significantly fewer days of agricultural labor than those without infants. Lastly, we find that during the year before birth, greater rainfall during kiremt as well as the dry season is associated with a lower likelihood of six months of exclusive breastfeeding, potentially due to the early introduction of complementary foods. Our findings indicate that agricultural labor demands may in part drive breastfeeding behaviors, leading to "sub-optimal" feeding practices in the short-term, but resulting in improved household food security in the longer-term.
我们研究了埃塞俄比亚气候条件、母乳喂养行为和母亲时间利用之间的关系。婴儿喂养方式是儿童营养的重要预测因素,可能受到多种因素的影响,包括母亲从事农业劳动的时间、粮食安全、文化信仰和产前护理。我们使用生活水平测量研究的面板数据,调查儿童出生后第一年及出生前一年的气候条件与纯母乳喂养持续时间之间的联系。然后,我们探讨了一种潜在机制:女性的农业劳动。结果表明,儿童出生后第一年主要农业季节(基尔梅特季)的降雨量对纯母乳喂养的持续时间起着重要作用。与平均每月5厘米的基尔梅特降雨量相比,平均每月25厘米的降雨量会使纯母乳喂养达到推荐的六个月时长的可能性降低20个百分点。更多的基尔梅特降雨量与女性用于种植和收获的天数增加有关,而且在降雨量较高时,有婴儿的女性从事农业劳动的天数并不比没有婴儿的女性显著减少。最后,我们发现,在出生前一年,基尔梅特季以及旱季降雨量增加与纯母乳喂养六个月的可能性降低有关,这可能是由于过早引入辅食所致。我们的研究结果表明,农业劳动需求可能在一定程度上推动了母乳喂养行为,短期内导致“次优”的喂养方式,但从长期来看会改善家庭粮食安全。
