Paid Leave & Breastfeeding: Does Policy Impact Infant Health?

"A new study examines how paid family leave policies in California and New Jersey affect breastfeeding rates, offering insights for policymakers nationwide."


Paid family leave policies are gaining traction across the United States, aiming to support parents during the crucial period following childbirth. While the potential benefits of such policies are widely acknowledged, the US remains the only high-income nation without a national mandate. This makes understanding the impact of state-level policies, like those in California and New Jersey, all the more critical.

Recognizing that early return to work can negatively affect breastfeeding practices, maternal health, and even infant immunization rates, researchers are delving into the real-world effects of these policies. Prior studies have often been correlational, making it difficult to isolate the true impact of paid leave. Now, a new study uses a robust quasi-experimental approach to provide clearer evidence on how these policies influence breastfeeding practices.

This article explores the findings of that study, which examines the impact of paid family leave policies in California and New Jersey on breastfeeding rates. By comparing changes in these states with those without such policies, the research sheds light on whether paid leave truly improves breastfeeding outcomes – and for whom.

Does Paid Family Leave Boost Breastfeeding?

The study, published in the American Journal of Public Health, analyzed data from the National Immunization Survey (NIS) between 2003 and 2015. This included a large sample of over 300,000 children, offering a broad and diverse dataset to assess the impact of California and New Jersey's paid family leave policies, which allow for up to 6 weeks of partially paid leave.

Researchers focused on several key breastfeeding outcomes, including whether a child was ever breastfed, whether they were exclusively breastfed at 3 and 6 months, and the duration of any breastfeeding and exclusive breastfeeding. They then used a 'difference-in-differences' approach, comparing changes in breastfeeding rates in California and New Jersey after the implementation of their policies, with changes in states that didn't have paid leave policies. This method helps to isolate the specific impact of the policies, controlling for other factors that might influence breastfeeding.

  • Ever breastfed
  • Exclusively breastfed at 3 and 6 months
  • Still breastfed at 6 and 12 months
  • Duration of any breastfeeding
  • Exclusive breastfeeding duration
The results indicated that paid family leave policies led to a modest increase in the likelihood of exclusive breastfeeding at 6 months. However, the impact on other breastfeeding outcomes was not statistically significant across the entire sample. Further analysis revealed a more nuanced picture, with certain subgroups experiencing greater benefits than others.

Designing Policies for Equitable Impact

The study's findings highlight the importance of carefully designing paid family leave policies to ensure they benefit all segments of the population. While the policies in California and New Jersey did improve exclusive breastfeeding at 6 months, the benefits were more pronounced among married, White, higher-income, and older mothers.

This suggests that existing policies may not adequately support low-income families, who may struggle to afford even a partial loss of wages. To address this disparity, future policies should consider more generous wage replacement and targeted outreach to vulnerable populations.

Ultimately, this research underscores the potential of paid family leave to improve infant health outcomes, but also emphasizes the need for ongoing evaluation and refinement to maximize its impact and ensure equitable access for all families.

Everything You Need To Know

1

What were the main findings regarding Paid Family Leave and breastfeeding?

The study found that Paid Family Leave policies in California and New Jersey led to a slight increase in exclusive breastfeeding at 6 months. This is significant because exclusive breastfeeding for the first six months is recommended by health organizations for optimal infant health. The findings suggest that providing paid leave can support mothers in adhering to these guidelines, potentially improving infant health outcomes. However, the impact on other breastfeeding outcomes was not statistically significant across the entire sample.

2

What research method was used to assess the impact of Paid Family Leave?

The study used the 'difference-in-differences' approach. This method compares changes in breastfeeding rates in California and New Jersey, after the implementation of Paid Family Leave policies, with changes in states that did not have such policies. This approach helps to isolate the specific impact of the policies, controlling for other factors that might influence breastfeeding, providing clearer evidence on how these policies influence breastfeeding practices.

3

What specific aspects of breastfeeding were examined in the study?

The key breastfeeding outcomes examined in the research included whether a child was ever breastfed, whether they were exclusively breastfed at 3 and 6 months, and the duration of any breastfeeding and exclusive breastfeeding. These metrics are crucial because they reflect different aspects of breastfeeding practices and their potential impact on infant health. Assessing these outcomes allows researchers to determine the effectiveness of Paid Family Leave policies in supporting various breastfeeding behaviors.

4

How does Paid Family Leave potentially affect breastfeeding practices?

Paid Family Leave policies can impact breastfeeding practices because they provide mothers with the time and financial security needed to breastfeed. Early return to work can negatively affect breastfeeding, maternal health, and infant immunization rates. By allowing mothers to take time off work, these policies can help them continue breastfeeding for a longer duration, as demonstrated by the study's findings on exclusive breastfeeding at 6 months, which is a very important aspect of infant health.

5

Were there any disparities in the impact of Paid Family Leave, and what does this mean?

The research indicated that the benefits of Paid Family Leave were more pronounced among specific subgroups, including married, White, higher-income, and older mothers. This disparity implies that policy design needs to consider the diverse needs of different populations to ensure equitable access to benefits. The implication is that policies should be carefully designed to address these disparities and provide more inclusive support for all mothers, regardless of their socioeconomic status or demographic characteristics, to ensure that Paid Family Leave effectively improves breastfeeding outcomes across the board.
