TORO HUERTA, Carol et al. Characteristics and motivations of donors to the human milk ba nk in Dr. Sótero del Rio Hospital, Chile. Rev. chil. nutr. [online]. 2020, vol.47, n.1, pp.105-113. ISSN 0717-7518.

This study sought to describe characteristics, motivations, barriers, and sources of information of human milk donors to the milk bank at Dr. Sótero del Río Hospital, Chile.


A descriptive and cross - sectional study was carried out. We conducted a 15-question telephone survey in 82 women who were at least one-time milk donors between 2015 and 2017. Statistical analysis included frequencies and percentages for categorical variables and measures of central tendency and dispersion for quantitative variables. We calculated 95% confidence intervals (CI).


The mean age of donors was 31.34,6 years; 92.7% were married or were living with their partner and 58.5% (95% CI of 47.1– 69.3) had completed higher education. The main motivation for donating was helping others (41.5% [95% CI of 30.7– 52.9]). The primary sources of knowledge on milk donations were the internet and social networks (43.9% [IC 95% 33.0– 55.3]), followed by health personnel 32% (95% CI of 22.9– 44.2).


The donor profile in CASR's milk bank is a young woman, with a stable partner and high educational level. These results could provide useful information to improve strategies for human milk donation.
