Adversity and patterns of health visiting in England: Evidence from linked administrative data and expert-by-experience workshops
Using linked administrative data and expert workshops, this study found that health visiting services in England delivering high-intensity, age-distributed support across the 0–5 year range—rather than focusing primarily on babies—are associated with improved developmental outcomes and reduced inequalities for families facing adversity.

In England, every family with a young child has access to a universal public health service known as health visiting. Led by specialist nurses, these teams visit homes and community centers to support children from birth until their fifth birthday. The core idea behind this service is "proportionate universalism." This means that while every family receives a standard set of check-ins and guidance, those facing greater difficulties receive more intensive support. The goal is to build a trusting relationship that helps parents navigate challenges, spot emerging needs, and connect with other services before small problems become crises. However, because these services are managed locally, the way they are delivered varies significantly from one town to another. Some areas might focus heavily on the first few months of life, while others spread their support out over several years. Understanding whether these different approaches actually change outcomes for the most vulnerable families is a question that has long puzzled policymakers and researchers.
A recent study set out to map these variations and see if they matter. Researchers analyzed linked records from health services and hospitals across 57 local areas in England, covering the years 2018 to 2020. They focused specifically on families facing adversity, defined by mothers who had been hospitalized for mental health issues, alcohol or substance misuse, or violence and abuse in the three years before giving birth. By looking at how health visitors interacted with these families—counting the number of visits, when they happened, and whether they were face-to-face or by phone—the team used a statistical method to group local areas into three distinct patterns of service delivery. They then compared the health and development of children in these different areas to see if one pattern worked better than the others.
The analysis revealed three clear ways that local areas were organizing their support. The first pattern involved a lower intensity of support spread evenly across the entire age range from zero to five years. The second pattern also offered a lower intensity of support, but it was heavily concentrated in the very early months of a child's life, with fewer visits as the child grew older. The third pattern was characterized by a higher intensity of support that was also spread evenly across the full zero-to-five-year age range. This third approach stood out because it involved more face-to-face visits in the home, longer conversations, and a consistent presence as the child grew from a baby into a toddler, rather than tapering off after the first year.
To understand what these numbers meant in real life, the researchers held workshops with parents who had lived through the very adversities the study examined. The feedback was nuanced. Mothers who had experienced mental health difficulties found the frequent, home-based visits to be a lifeline, offering a safe space to be understood and supported. However, for parents dealing with addiction or domestic violence, the same home visits could feel stressful or even dangerous. Some felt scrutinized or feared that an abuser might manipulate the relationship with the visitor. These parents often preferred clinic visits, which allowed them to leave the house and maintain a sense of privacy. This highlighted a complex reality: the very feature that made the service effective for some—intensive, home-based contact—could be a barrier for others.
When the researchers looked at the hard data on child outcomes, a clear picture emerged regarding the third pattern. Children in areas where health visiting was delivered with high intensity across the full zero-to-five-year range were less likely to miss expected developmental milestones at age two and a half. Specifically, these children showed better progress in personal-social skills, problem-solving, and gross motor abilities. Furthermore, in these same high-intensity areas, the gap in injury-related hospital admissions between children facing adversity and those who were not was significantly smaller. In other words, the more consistent and intensive the support was across the early years, the more it seemed to level the playing field for the most vulnerable families.
The study did not find a similar clear link for maternal emergency room visits, and the researchers were careful to note that this could be because the areas that chose the high-intensity model were already the ones with the highest levels of need. It is possible that the service successfully offset the high risk in these areas, or that the pattern simply had no effect on that specific outcome. The researchers also emphasized that their findings are based on observational data, meaning they can show a strong association but cannot prove that the service pattern caused the improvement. Nevertheless, the results suggest that a model of sustained, relationship-based contact that continues well beyond infancy aligns with the theoretical goals of the service and appears to mitigate disadvantage.
Ultimately, this work provides a rare glimpse into how a universal service operates in practice across a whole country. It shows that while local variation is inevitable, common patterns do exist. The findings suggest that spreading intensive support across the entire early childhood period, rather than focusing only on the newborn stage, may be a more effective way to reduce inequalities for families facing the toughest challenges. While the study does not offer a single "best" way to deliver care for every situation, it provides evidence that the principle of proportionate universalism, when enacted with sustained intensity, has the potential to make a tangible difference in the lives of children and their families.
