Contraception. 2025 Mar;143:110773. doi: 10.1016/j.contraception.2024.110773. Epub 2024 Nov 22.
This study aimed to examine the association between state-level Immigration Policy Climate (IPC) and the use of most or moderately effective contraceptive methods among US-born White, US-born Mexican-origin, and foreign-born Mexican-origin women.
We linked nationally representative survey data from three waves of the National Survey of Family Growth (2013-2019) with a novel and dynamic state-level measure of IPC. We compared the use of a most or moderately effective contraceptive method at the time of the survey among the three ethnicity and nativity groups alone and as an interaction with state IPC index score above or below the national mean in the year of the survey. We used multivariable logistic regression to adjust for individual- and state-level characteristics and test for heterogeneity of the effect of IPC.
Weighted study sample included 31,528,602 respondents: 26,029,129 (82.5%; unweighted n = 5441) non-Latina White, 2,958,960 (9.4%; unweighted n = 971) US-born Mexican-origin, and 2,540,513 (8.1%; unweighted n = 719) foreign-born Mexican-origin. After adjusting for confounders, living in a state with a more inclusive immigration policy environment was associated with higher use of moderately or most effective contraception among Mexican-origin respondents, both US- (59.8% vs 52.2% less inclusive) and foreign-born (62.1% vs 55.9% less inclusive), but not US-born White (65.2% vs 67.8% less inclusive) respondents.
Our results support the "spillover" hypothesis; more exclusionary immigration policies were associated with lower utilization of effective contraceptive methods among both US-born Mexican-origin and Mexican immigrant women.
Mexican-origin women in states with more inclusive immigration policies are more likely to use effective contraception than those in states with exclusionary policies; this suggests that immigration policy climate may "spill over" into US-born Mexican-origin populations.
本研究旨在探讨州级移民政策环境（IPC）与美国出生的白人、美国出生的墨西哥裔以及外国出生的墨西哥裔女性使用最有效或中等有效的避孕方法之间的关联。
我们将来自三轮全国家庭成长调查（2013 - 2019年）的具有全国代表性的调查数据与一种新颖且动态的州级IPC测量方法相结合。我们比较了在调查时三个种族和出生组单独使用最有效或中等有效的避孕方法的情况，以及作为与调查年份中州IPC指数得分高于或低于全国均值的交互作用下的使用情况。我们使用多变量逻辑回归来调整个体和州级特征，并检验IPC效应的异质性。
加权研究样本包括31,528,602名受访者：26,029,129名（82.5%；未加权n = 5441）非拉丁裔白人、2,958,960名（9.4%；未加权n = 971）美国出生的墨西哥裔以及2,540,513名（8.1%；未加权n = 719）外国出生的墨西哥裔。在调整混杂因素后，生活在移民政策环境更包容的州与墨西哥裔受访者（包括美国出生的[59.8%对包容性较低的52.2%]和外国出生的[62.1%对包容性较低 的55.9%]）更多地使用中等或最有效的避孕方法相关，但与美国出生的白人受访者（65.2%对包容性较低的67.8%）无关。
我们的结果支持“溢出”假说；更具排他性的移民政策与美国出生的墨西哥裔和墨西哥移民女性中有效避孕方法的较低使用率相关。
与处于排他性政策州的女性相比，处于移民政策更包容州的墨西哥裔女性更有可能使用有效避孕方法；这表明移民政策环境可能“溢出”到美国出生的墨西哥裔人群中。
