Between 1980 and 2019, the number of incarcerated women rose by more than 700%. Rising imprisonment of women corresponds with an increase in incarcerated lactating people. In 2018, California signed Assembly Bill (AB) 2507, requiring county jails to develop and implement a breast milk feeding policy for incarcerated women who wish to express their breast milk. We conducted a cross-sectional, descriptive study to determine if California's 58 counties created policies compliant with AB2507. Additionally, policies were analyzed for inclusion of evidence-based breastfeeding and lactation management practices and given a letter grade for their performance. Public records act requests were sent to all California counties, requesting their breast milk feeding policies. Of the 55 counties that responded, 51 had policies. Twenty-eight (51%) counties were in full compliance and 27 (49%) counties lacked compliance. No counties received letter grade A and 48 (87%) counties received letter grade C or below. Results reveal a discrepancy between legally compliant policies and evidence-based practices. The California county jail management needs increased surveillance to ensure policies are in full compliance and reflect best practices. Further research is required to investigate the actual implementation of compliant written breastfeeding policies.

母乳喂养和监禁：对加州县监狱书面母乳喂养政策的分析。

1980年至2019年间，被监禁的女性人数增加了700%以上。女性入狱人数的增加与被监禁哺乳期人数的增加相对应。2018 年，加州签署了议会法案 (AB) 2507，要求县监狱为希望吸出母乳的被监禁妇女制定并实施母乳喂养政策。我们进行了一项横断面、描述性研究，以确定加州 58 个县制定的政策是否符合 AB2507。此外，还对政策进行了分析，以纳入基于证据的母乳喂养和哺乳管理实践，并对其绩效进行字母评分。公共记录法案请求已发送至加州所有县，要求制定母乳喂养政策。在做出回应的 55 个县中，51 个县制定了政策。28 个县 (51%) 完全合规，27 个县 (49%) 未达标。没有县获得 A 级字母，48 个县 (87%) 获得 C 级或以下字母。结果显示，合法合规的政策与循证实践之间存在差异。加州县监狱管理部门需要加强监督，以确保政策完全符合并反映最佳实践。需要进一步研究来调查合规书面母乳喂养政策的实际实施情况。
