A home-based nutrition and parenting program in France successfully maintained and even increased its reach to vulnerable families after pausing during COVID-19 and restarting during the cost-of-living crisis. According to Gram Research analysis, eligibility for the program rose from 29.7 percent before the pandemic to 33.6 percent after resumption, while participation remained stable at 24.6 percent. Dietitians reported high satisfaction, and the introduction of adaptive strategies like pre-visit COVID-19 screening reduced missed appointments, demonstrating that flexible, personalized home-based services can sustain engagement with socially disadvantaged families even during major crises.
A major study in France tracked a program that sends dietitians to the homes of pregnant women and new parents facing financial hardship or social isolation. When the COVID-19 pandemic forced a six-month pause, researchers wanted to know if the program could bounce back and still reach the families who needed it most. The good news: not only did the program resume successfully, but it actually reached more eligible families afterward. The study shows that flexible, personalized home-based services can maintain strong engagement with vulnerable families even during major disruptions like pandemics and economic crises.
Key Statistics
A mixed-methods study of 5,744 pregnant women in France found that program eligibility increased from 29.7 percent before the COVID-19 pandemic to 33.6 percent after the program resumed, suggesting rising social vulnerability during economic crises.
Among eligible families in the ECAIL trial, 78.3 percent received social or medical benefits, 58.7 percent did not have employment as their main income source, and 19 percent experienced three or more simultaneous vulnerabilities.
Dietitians delivering home-based services reported high satisfaction with program resumption, and the introduction of a pre-visit COVID-19 questionnaire was associated with fewer failed home visits during the cost-of-living crisis.
Participation in the home-based intervention remained stable at 24.6 percent among eligible women before and after the pandemic, indicating sustained engagement despite major contextual disruptions.
The Quick Take
- What they studied: Whether a home-based nutrition and parenting program for struggling families could maintain its reach and effectiveness after being paused during the COVID-19 pandemic and then restarted during a cost-of-living crisis.
- Who participated: 5,744 pregnant women screened at a maternity hospital in Lille, France, who were experiencing social vulnerability such as poverty, unstable housing, or social isolation. About 30 to 34 percent met eligibility criteria, and roughly one-quarter of eligible women participated in the program.
- Key finding: The program actually reached more eligible families after resuming (33.6 percent) compared to before the pandemic (29.7 percent), and participation rates remained stable at about 25 percent. Dietitians reported high satisfaction, and participants appreciated the home visits, especially for combating loneliness.
- What it means for you: If you or someone you know is a struggling parent or pregnant person, personalized home-based support programs can adapt and continue serving you even during major crises. The key is flexibility and understanding what families actually need. However, this study focused on one program in France, so results may differ in other locations or countries.
The Research Details
Researchers used a mixed-methods approach, meaning they combined numbers (quantitative data) with personal stories and observations (qualitative data). They analyzed 5,744 eligibility questionnaires collected at a maternity hospital before the pandemic, during the suspension, and after the program restarted. They also conducted a focus group with six dietitians who delivered the home-based intervention to understand their experiences, challenges, and adaptations. This combination of data sources allowed researchers to see both the big picture (how many families were reached) and the human experience (how providers and families felt about the program). The program itself targeted pregnant women and families with babies up to age 2 who experienced at least one form of social vulnerability, such as low income, unstable housing, unemployment, or social isolation.
Understanding how programs can adapt and survive major disruptions is crucial for public health. The COVID-19 pandemic and cost-of-living crisis created unprecedented challenges for healthcare systems and vulnerable families. By studying how this program maintained its reach and effectiveness, researchers provide evidence that flexible, person-centered approaches can work even when circumstances change dramatically. This matters because vulnerable families often face the most barriers to accessing support, and knowing what strategies keep them engaged helps policymakers and healthcare providers design better services.
This study has several strengths: it examined a large number of questionnaires (5,744), included both quantitative and qualitative data for a complete picture, and tracked the program across multiple time periods. The researchers also directly involved the healthcare providers delivering the intervention, which adds credibility to their findings. However, the focus group included only six dietitians, which is a small number, so their perspectives may not represent all providers. The study was conducted in one hospital in France, so findings may not apply to other countries or healthcare systems with different resources or structures. Additionally, the study examined reach and participation but did not measure whether the intervention actually improved child health outcomes.
What the Results Show
Before the pandemic, 29.7 percent of the 955 pregnant women screened at the maternity hospital met eligibility criteria for the program. After the program resumed following the six-month COVID-19 suspension, eligibility increased to 33.6 percent among 849 women screened. This increase suggests that social vulnerability actually grew during the pandemic and cost-of-living crisis, which makes sense given the economic hardship many families faced. Among eligible women, participation remained stable at about 24.6 percent (443 women participated), meaning the program maintained its ability to engage families despite the disruption. The types of vulnerabilities families experienced stayed similar before and after: about 78 percent received social or medical benefits, 59 percent did not have employment as their main income source, 24 percent experienced financial hardship, 15 percent reported social isolation, 6 percent lived in unstable housing, and 19 percent had three or more vulnerabilities simultaneously. When the program restarted, dietitians introduced a COVID-19 screening questionnaire before home visits, which reduced the number of failed or missed appointments.
The qualitative findings from the focus group with dietitians revealed important insights about how the program adapted. Dietitians reported satisfaction with resuming home visits and noted that participants were enthusiastic about the program’s return. Providers highlighted that home visits were particularly valuable for addressing social isolation, which had worsened during lockdowns. The introduction of the pre-visit COVID-19 questionnaire appeared to help both providers and families feel safer and more prepared, reducing logistical problems. Dietitians also described adapting their approach to address the increased economic stress families faced during the cost-of-living crisis, suggesting they were responsive to changing family needs. The integration of quantitative and qualitative data showed that provider engagement remained strong despite strain on hospital services, indicating that staff commitment to vulnerable families persisted even under difficult circumstances.
This study adds to existing research showing that home-based interventions can be effective for reaching vulnerable families. Previous research has demonstrated that in-person, personalized services tend to have better engagement rates with socially disadvantaged populations compared to clinic-based or group programs. This study extends that knowledge by showing that home-based programs can maintain their effectiveness even after major disruptions. The finding that eligibility actually increased during the pandemic aligns with other research documenting rising social vulnerability during COVID-19 and the cost-of-living crisis. The study also contributes to implementation science, a field that studies how to deliver healthcare programs effectively in real-world settings. By examining both reach (how many eligible people the program contacted) and participation (how many actually engaged), this research provides a more complete picture than studies that only measure one outcome.
The study was conducted at a single maternity hospital in Lille, France, so findings may not apply to other countries, healthcare systems, or populations. The focus group included only six dietitians, which is a small sample and may not represent the experiences of all providers. The study measured reach and participation but did not examine whether the intervention actually improved child health outcomes or reduced obesity rates, so we cannot conclude from this research alone that the program works. The study did not include a comparison group or control condition, so we cannot be certain that changes in eligibility or participation were due to the program’s adaptations versus other factors in the community. Additionally, the study did not measure the quality of home visits or the depth of engagement, only whether visits occurred. Finally, the research was published in 2026, so long-term follow-up data on child health outcomes are not yet available.
The Bottom Line
According to Gram Research analysis, healthcare systems and community organizations should invest in flexible, home-based services for vulnerable families, as these programs can maintain reach and engagement even during major crises. Providers should consider implementing adaptive strategies like pre-visit screening questionnaires to reduce barriers and improve safety. Policymakers should prioritize funding for programs that serve socially disadvantaged families, as these populations face the greatest barriers to accessing support. However, these recommendations are based on implementation data from one program in France, so they should be adapted to local contexts and combined with evidence from other studies. The confidence level for these recommendations is moderate: the study provides good evidence that home-based programs can adapt and survive disruptions, but more research is needed to confirm that these adaptations actually improve family health outcomes.
Pregnant women and parents of young children experiencing financial hardship, unstable housing, social isolation, or unemployment should know that home-based support programs can help and can adapt to reach them even during difficult times. Healthcare providers, hospital administrators, and policymakers should care about this research because it shows how to maintain services for vulnerable populations during crises. Public health officials planning for future emergencies should consider home-based service models as a resilient approach. Researchers studying implementation science and health equity will find this study valuable. People who should be cautious about applying these findings include those in countries with very different healthcare systems or social safety nets, and those seeking evidence that the program actually improves child health outcomes (this study does not provide that evidence).
The program in this study provided services from pregnancy through age 2, so families would receive support over approximately three years. Dietitians delivered regular home visits during this period. The study did not measure how quickly families might see benefits like improved nutrition knowledge or reduced social isolation, but qualitative feedback suggested participants valued the visits immediately upon resumption. Long-term health outcomes for children would likely take years to measure and were not assessed in this research. If you or someone you know is considering joining a similar program, expect ongoing support over several years rather than a short-term intervention.
Frequently Asked Questions
Can home-based health programs continue to work during a pandemic or economic crisis?
Yes, according to research from the ECAIL trial in France, home-based programs can maintain and even increase their reach to vulnerable families during major crises. The key is flexibility: the program adapted by adding COVID-19 screening and remained responsive to changing family needs, resulting in stable participation rates of 24.6 percent.
What types of families does a home-based nutrition program serve?
Home-based programs typically serve families experiencing social vulnerability, including those with low income (78 percent received benefits in this study), unstable employment (59 percent), financial hardship (24 percent), social isolation (15 percent), or unstable housing (6 percent). Many families face multiple challenges simultaneously.
How do home visits help families dealing with social isolation?
According to dietitians in this study, home visits provide direct personal contact and support, which is especially valuable for isolated families. The visits offer both practical nutrition guidance and emotional connection, addressing loneliness that often worsens during crises like lockdowns.
What makes a home-based program successful with struggling families?
This research suggests that success depends on flexibility, personalization, and provider commitment. Adaptive strategies like pre-visit screening, responsive communication, and willingness to adjust services based on family needs help maintain engagement. Provider satisfaction and genuine care for families also matter.
Did the program actually improve child health outcomes?
This study measured reach and participation but did not examine whether the program improved child health outcomes or reduced obesity rates. Researchers tracked whether families engaged with the program, not whether children’s health improved, so additional research is needed to confirm effectiveness.
Want to Apply This Research?
- Track appointment attendance and completion of home visits using a simple calendar feature. Record the date, time, and type of visit (nutrition counseling, parenting support, social connection). Note any barriers that prevented attendance (transportation, illness, childcare) and solutions that helped (reminder texts, flexible scheduling). This data helps identify patterns and supports program improvement.
- Use the app to set one small, achievable nutrition or parenting goal before each home visit (for example, ‘introduce one new vegetable to baby’ or ‘practice one calming technique when stressed’). Share your goal with your dietitian during the visit and report back on progress at the next appointment. This creates accountability and helps you feel more engaged with the program.
- Create a simple tracking system within the app to monitor how the program is helping you. Rate your confidence in nutrition knowledge, sense of social connection, and stress level on a scale of 1 to 10 before your first visit and then monthly. Also track attendance at appointments and note any changes in how you feel about parenting or family life. Share these trends with your healthcare provider to adjust the program to your needs.
This research describes one program’s experience maintaining services during the COVID-19 pandemic and cost-of-living crisis. The findings apply specifically to a maternity hospital in Lille, France, and may not generalize to other locations, healthcare systems, or populations. This study measured program reach and participation but did not evaluate whether the intervention actually improved child health outcomes or reduced obesity rates. If you are pregnant or a parent of a young child, consult with your healthcare provider about whether a similar program is available in your area and whether it is appropriate for your individual circumstances.
