Health visitor support significantly boosts postpartum smoking abstinence rates

A woman quits smoking during pregnancy. The months after her baby arrives are some of the hardest of her life—sleep-deprived, hormonal, stressed. The urge to smoke creeps back. Without support, many women light up again. A study from the University of East Anglia set out to test whether trained health visitors could change that pattern, and the results suggest they can.

Researchers followed 886 women across England and Scotland who had successfully quit smoking before or during pregnancy. Half received standard postpartum care with no smoking-specific support. The other half got something different: the BabyBreathe programme, a package designed to keep new mothers smoke-free through the vulnerable months after birth. The intervention paired one-to-one advice from trained health visitors with digital tools—an app, a website, text message reminders—and a physical relapse-prevention kit mailed to families after the baby arrived. Support continued through routine health visitor appointments for up to a year.

The difference was measurable. Among women who received the full BabyBreathe intervention as designed, 57.6 percent remained smoke-free at the 12-month mark. In the standard care group, that figure was 49.9 percent. The gap—nearly eight percentage points—may sound modest until you consider what it means: more mothers breathing clean air, more babies protected from secondhand smoke, more families avoiding the cascade of health risks that smoking brings.

The programme itself was the product of more than a decade of work. Researchers, health professionals, and women themselves had collaborated to design something practical and deliverable. Health visitors—the nurses who visit new mothers at home—received training in smoking relapse prevention, a skill they had never been formally taught before. They learned to praise women for quitting during pregnancy, to offer concrete alternatives when cravings hit, and to involve partners and family members in the effort to keep the home smoke-free.

Professor Caitlin Notley, who led the research at UEA's Norwich Medical School, framed the stakes clearly. Quitting smoking while pregnant is hard. Staying quit after the baby arrives can be harder. "Too often, support ends once a woman has quit," she said, "even though the stressful months after birth are when many women are most at risk of returning to smoking." The postpartum period—chaotic, exhausting, isolating for many—is precisely when relapse prevention matters most. Yet until now, health visitors had no training to address it.

The study had limitations. About one in five participants did not receive the full intervention due to health visitor staffing shortages, missed appointments, or administrative gaps. The women who participated were also more educated and less economically deprived than the general population, which may mean the programme's real-world effectiveness could differ. Still, the core finding held: when health visitors were trained and supported to deliver specialist relapse prevention advice, women stayed smoke-free at significantly higher rates.

The implications ripple outward. A woman who quits smoking and stays quit reduces her risk of smoking-related disease—heart disease, lung cancer, stroke—to nearly the same level as someone who never smoked. Her baby avoids the developmental harms of secondhand smoke exposure. Her children grow up in a home where smoking is not modeled as a normal response to stress. The Institute of Health Visiting, which collaborated on the research, noted that health visitors are uniquely positioned to deliver this support as part of their routine work with new families. What was missing was the training and the evidence. Now both exist. The question is whether health services will act on them.
