What This Means
This research suggests that a multimedia educational program—delivered through a dedicated website and social media channels over about seven months—was associated with healthier eating habits and lifestyle behaviors among Italian families. Among children and adolescents, those surveyed at the end of the program ate more fruits, vegetables, and fish, were more physically active, spent less time on screens, and were more likely to follow a Mediterranean-style diet compared to those surveyed at the start. Among adult women, body weight (measured by BMI) appeared lower at the end of the program, and their diets included more vegetables, fish, legumes, and nuts, with a large increase in the proportion considered to have good Mediterranean diet adherence (from about 11% to 35%).
It is important to understand the study's limitations when interpreting these findings. The study did not have a control group—meaning there was no comparison group that did not receive the program—and the before-and-after groups were not the same individuals tracked over time but rather different samples from the same broader population surveyed at two time points. This means factors other than the program could explain some or all of the observed differences. Additionally, very few adult men participated, so findings in adults apply only to women.
Despite these limitations, this research suggests that family- and school-based digital health education programs, when developed and supervised by health professionals, may be a promising tool for encouraging healthier diets and lifestyles. The findings support further investigation with more rigorous study designs, including control groups and tracking of the same individuals over time.
