According to Gram Research analysis of a 2024 study of 382 mothers in French Guiana, only 22.3% of babies received exclusively breast milk for the first four months, despite 91.6% of babies being breastfed at some point. Early introduction of formula supplements in hospitals—given to 77.4% of breastfed infants—was the strongest factor preventing exclusive breastfeeding. Younger mothers and those with higher education were significantly more likely to exclusively breastfeed, while mothers born in French Guiana faced greater challenges than those born in Haiti.
A new study of nearly 400 mothers in French Guiana reveals that while most babies are breastfed, very few receive only breast milk for the first four months as health experts recommend. Researchers found that young mothers and those with more education were more likely to exclusively breastfeed, while early use of formula supplements and limited breastfeeding support made it harder for mothers to stick with exclusive breastfeeding. The findings highlight the need for better, culturally sensitive support to help all mothers in this diverse region successfully breastfeed their babies.
Key Statistics
A 2024 cross-sectional study of 382 mothers in French Guiana found that only 22.3% of babies received exclusively breast milk for the first four months, falling short of WHO and French national recommendations.
In the same 2024 study, 77.4% of breastfed infants received formula supplements while still in the maternity hospital, with this early supplementation reducing the likelihood of sustaining exclusive breastfeeding by 70%.
Mothers under 20 years old in French Guiana were 4.2 times more likely to exclusively breastfeed for four months compared to older mothers, according to the 2024 research of 382 mother-child pairs.
Professional breastfeeding support dropped from 69.6% during hospital stay to 40.9% after discharge in French Guiana, with 22.8% of mothers reporting they wished they had received support but did not.
The Quick Take
- What they studied: How many mothers in French Guiana exclusively breastfeed their babies for the first four months, and what factors help or prevent them from doing so.
- Who participated: 382 mothers who gave birth in French Guiana’s three maternity hospitals between March and October 2024. Researchers called them about 12 months after delivery to ask about their breastfeeding experiences.
- Key finding: Only 22.3% of babies received only breast milk for the first four months, even though 91.6% of babies were breastfed at some point. Most breastfed babies (77.4%) also received formula supplements while still in the hospital.
- What it means for you: If you’re a mother in French Guiana planning to breastfeed, know that exclusive breastfeeding is challenging but possible—especially with proper support. Younger mothers and those with higher education were more successful, suggesting that targeted help and education could improve outcomes for all mothers.
The Research Details
Researchers conducted a telephone survey with 382 mothers who had given birth in French Guiana’s maternity hospitals. They called mothers approximately 12 months after delivery and asked detailed questions about how they fed their babies, using a standardized questionnaire designed to measure infant feeding practices. The study was conducted between March and October 2024 and included multilingual interviewers to accommodate the region’s cultural diversity.
The researchers then analyzed the data to find patterns—looking at which mothers successfully exclusively breastfed for four months and which factors made this more or less likely. They used statistical methods to identify associations between maternal characteristics (like age and education) and breastfeeding success, while accounting for other variables that might influence the results.
This approach allowed researchers to capture real-world breastfeeding practices in French Guiana, a region with significant economic inequality and healthcare access challenges that hadn’t been well-studied recently.
French Guiana is a diverse territory with cultural differences, economic disparities, and healthcare system challenges that make breastfeeding support inconsistent. Without recent, accurate data specific to this population, health officials couldn’t design appropriate programs. This study provides the first representative snapshot of actual breastfeeding practices in the region, allowing policymakers to understand where support is most needed.
This study’s strengths include its large sample size (382 mothers), multicenter design (covering all three maternity hospitals), and use of standardized international feeding indicators. The multilingual interviewers helped ensure accurate data collection across the diverse population. However, the study relied on mothers’ recall of events from up to 12 months earlier, which can be imperfect. The study was cross-sectional (a snapshot in time) rather than following mothers over time, so it shows associations but not definitive cause-and-effect relationships.
What the Results Show
The study found that breastfeeding is common in French Guiana—91.6% of babies were ever breastfed, and 89.8% received breast milk while in the maternity hospital. However, exclusive breastfeeding (breast milk only, no formula) was much less common. Only 51.6% of babies ever received exclusive breastfeeding, and just 20.1% received only breast milk while in the hospital. Most importantly, only 22.3% of babies were exclusively breastfed for the full four months—the target set by France’s national nutrition program.
A major barrier emerged: 77.4% of breastfed babies also received formula supplements while still in the maternity hospital, primarily infant formula. This early introduction of formula was strongly associated with mothers stopping exclusive breastfeeding. The median duration of exclusive breastfeeding was only three months, falling short of the four-month target.
Breastfeeding support varied significantly. During the hospital stay, 69.6% of mothers received professional breastfeeding help, but this dropped to 40.9% after going home. Importantly, 22.8% of mothers said they wished they had received breastfeeding support but didn’t get it—suggesting unmet need for guidance.
The study identified specific groups more likely to exclusively breastfeed for four months: mothers under 20 years old were 4.2 times more likely to achieve this goal, and mothers with higher education were 2 times more likely. Conversely, mothers born in French Guiana were less likely to exclusively breastfeed compared to mothers born in Haiti (who were more likely to succeed). The overall median breastfeeding duration was six months, showing that many mothers continued breastfeeding beyond the exclusive period by adding other foods.
This is the first recent representative study of breastfeeding practices in French Guiana, so direct comparisons are limited. However, the 22.3% exclusive breastfeeding rate at four months is notably lower than rates in many developed countries and falls short of WHO recommendations. The high rate of early formula supplementation in hospitals aligns with patterns seen in other developed healthcare systems, where hospital practices sometimes undermine exclusive breastfeeding goals despite stated policies supporting it.
The study asked mothers to recall breastfeeding details from up to 12 months earlier, which can lead to imperfect memory. The study was conducted at one point in time rather than following mothers over months, so we can’t determine cause-and-effect—only associations. The sample, while representative of mothers using these three maternity hospitals, may not represent all mothers in French Guiana if some gave birth elsewhere or outside the healthcare system. Additionally, the study didn’t deeply explore cultural beliefs, family influences, or workplace barriers that might affect breastfeeding decisions.
The Bottom Line
Health officials in French Guiana should prioritize: (1) reducing unnecessary formula supplementation in maternity hospitals—the data shows this strongly undermines exclusive breastfeeding; (2) expanding breastfeeding support after hospital discharge, since support drops from 70% to 41% after mothers go home; (3) tailoring support to different maternal groups, recognizing that younger mothers and those with less education need additional help; (4) ensuring culturally appropriate guidance that respects the region’s diversity. These recommendations are supported by strong evidence from this study.
Mothers planning to breastfeed in French Guiana should care about these findings, as they highlight both the feasibility of breastfeeding (most mothers do it) and the specific challenges (maintaining exclusivity is hard). Healthcare providers, maternity hospitals, and public health officials should use these findings to redesign support systems. Policymakers should recognize that breastfeeding success requires coordinated effort across hospital, community, and workplace settings.
Exclusive breastfeeding for four months is a medium-term goal. Mothers should expect the first weeks to be most challenging, with hospital support being critical. The data shows that decisions made in the maternity hospital (especially about formula supplements) strongly influence whether mothers can maintain exclusive breastfeeding through the four-month mark. Realistic expectations: with proper support, exclusive breastfeeding through four months is achievable for motivated mothers, but without support, it becomes significantly harder.
Frequently Asked Questions
What percentage of babies in French Guiana are exclusively breastfed for four months?
Only 22.3% of babies in French Guiana receive exclusively breast milk for the first four months, according to a 2024 study of 382 mothers. This falls short of the four-month exclusive breastfeeding target set by France’s national nutrition program and WHO recommendations.
Why do so few mothers exclusively breastfeed in French Guiana?
The main barrier is early formula supplementation in hospitals—77.4% of breastfed babies received formula while still in the maternity ward. Limited breastfeeding support after hospital discharge (dropping from 70% to 41%) and socioeconomic factors also contribute to lower exclusive breastfeeding rates.
Which mothers are most successful at exclusively breastfeeding?
Mothers under 20 years old and those with higher education are significantly more likely to exclusively breastfeed for four months. Mothers born outside French Guiana also had higher success rates, suggesting cultural and structural factors influence breastfeeding outcomes.
Does breastfeeding support actually help mothers in French Guiana?
Yes—69.6% of mothers received professional breastfeeding support during hospital stays, and 22.8% of mothers reported wishing they had received more support. The gap between those who received help and those who wanted it suggests targeted support could significantly improve exclusive breastfeeding rates.
How long do mothers typically breastfeed in French Guiana?
The median breastfeeding duration is six months overall, but exclusive breastfeeding lasts only three months on average. While most babies (91.6%) are breastfed at some point, maintaining exclusive breastfeeding beyond the first few months is challenging without consistent support.
