School Administrator and Food Vendor Perspectives on Stocking and Promoting Healthier Offerings in Indonesian Primary Schools: Findings from a Pilot Study

Childhood overweight and obesity is a growing public health challenge in Indonesia, affecting approximately one in five school-aged children. Because children spend substantial time at school and frequently obtain meals and snacks from on-site canteens, these settings represent an important opportunity for nutrition-focused interventions. As an initial step towards understanding factors influencing canteen stocking decisions, we assessed perceived taste, acceptability, and feasibility of healthier local foods and beverages from the perspectives of canteen owners and school administrators (n = 10) across five primary schools (n = 2 urban, n = 3 rural) in Magelang, Indonesia. Participants completed in-person taste tests of selected food and beverage options and participated in in-depth interviews exploring drivers of stocking decisions. IndoMilk (multi-cereal, reduced-sugar dairy beverage) received the most favorable taste ratings and was perceived as the most feasible option to sell, followed by sate telur puyuh (braised quail eggs) and sate buah (fresh fruit skewers). In contrast, gethuk (cassava/coconut cake) and polo pendem (steamed tubers with boiled peanuts) were viewed as less appealing to children and unlikely to be sold. Participants identified children’s taste preferences, affordability, visual appeal, and profitability as key considerations influencing stocking decisions, while perceptions of nutrition varied. Findings from this pilot study highlight contextual factors shaping school canteen food environments and may inform future interventions aimed at introducing healthier options while accounting for children’s preferences and canteen operational constraints.
