An Innovative, Multimedia-Based Intervention for Promoting Changes in Lifestyle in Italian Families.

TL;DR

A multimedia educational program delivered via website and social media was associated with more favorable distributions of physical activity, dietary indicators, and Mediterranean diet adherence at 210 days compared to baseline among Italian children/adolescents and adult women.

Key Findings

Good Mediterranean diet adherence among children/adolescents increased from baseline to the 210-day assessment.

  • Good adherence to the Mediterranean diet increased from 46.8% at baseline to 61.4% at 210 days.
  • Mediterranean diet adherence was assessed using a modified KIDMED-derived score in children/adolescents.
  • The analysis included 329 children/adolescents at both assessment waves.
  • Data were compared at the group level rather than as paired longitudinal observations (uncontrolled repeated cross-sectional design).

Children/adolescents showed more favorable physical activity and screen time distributions at 210 days compared to baseline.

  • Higher physical activity and lower screen time were observed at 210 days than at baseline among children/adolescents.
  • The multimedia program was delivered through a dedicated website and social media channels over 210 days.
  • The study was an uncontrolled before-and-after evaluation based on online surveys.

Daily fruit intake, daily vegetable intake, and regular fish consumption were higher at 210 days than at baseline among children/adolescents.

  • More favorable dietary indicators were observed at 210 days compared to baseline in the children/adolescent group.
  • Specific dietary indicators identified as improved included daily fruit intake, daily vegetable intake, and regular fish consumption.
  • 329 children/adolescents were included in the analysis at both assessment waves.

Among adult female respondents, median BMI was lower at 210 days than at baseline.

  • The analysis of adults was restricted to women because only 11 adult males responded.
  • 119 adult female respondents were assessed at baseline and 122 at 210 days.
  • The median body mass index was lower in the 210-day respondent group than in the baseline respondent group.
  • Favorable differences were also observed for vegetable, fish/seafood, legume, and nut intake among adult women.

Median PREDIMED score and good Mediterranean diet adherence increased substantially among adult female respondents between baseline and 210 days.

  • The median PREDIMED score increased from 7.0 [6.0–8.0] at baseline to 9.0 [7.0–10.0] at 210 days.
  • Good Mediterranean diet adherence increased from 10.9% at baseline to 35.2% at 210 days among adult women.
  • Mediterranean diet adherence in adults was assessed using the PREDIMED score.

The study used an uncontrolled repeated cross-sectional before-and-after design, comparing group-level data rather than paired longitudinal observations.

  • Online surveys were administered at baseline and after 210 days to respondent samples from the same project population.
  • The study lacked a control group, limiting causal inference.
  • Data from the two assessment waves were compared at the group level, rather than as paired longitudinal observations.
  • The adult male sample was too small for analysis (only 11 respondents), so adult analyses were restricted to women.

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.
