UPAYA PEMBATASAN KONSUMSI MAKANAN DAN MINUMAN MANIS MELALUI MEDIA EDUKASI STUDI PADA ANAK SEKOLAH DASAR

The Theory of Planned Behavior (TPB) underlies an individual's intention to perform a specific behavior, including the
behavior of restricting the consumption of sugary foods and drinks in children. This study aimed to evaluate the
effectiveness of health promotion media based on TPB in limiting the intake of sugary foods and beverages among
children aged 3–5 years. An experimental study with a pre- and post-test control group design was conducted, involving
two groups with different educational media: the experimental group received messages through WhatsApp social media,
while the control group received conventional leaflet-based education. The results showed that WhatsApp text messaging
was effective in changing mothers' intentions, attitudes, subjective norms, and behaviors in restricting the consumption
of sugary foods and drinks in children (p < 0.05). In conclusion, WhatsApp text messaging effectively influences mothers'
intentions and behaviors in restricting sugary food and beverage intake in children, controlled by TPB constructs.
WhatsApp-based educational media can be recommended as a health promotion strategy to prevent excessive sugar
consumption in early childhood.
