ABSTRACT

Abstract Objective: The goal of this study was to design, develop, and evaluate a game for health, “Gustavo in Gnam's Planet” (“Gustavo”), aimed to improve knowledge on healthy foods and to increase consumption of healthy foods. Subjects and Methods: Eighty-three high school students were enrolled in the study. The game was designed and developed by a multidisciplinary team. Behavioral change theories were adopted to guide the design of the health messages. Participants were assessed about food frequency, healthy food knowledge, and the game's interest. Results: Forty-seven subjects (mean age, 14.9±1.0 years; 72.3 percent males) completed the study. At posttest, participants showed significant higher scores (i.e., increased knowledge) in the questionnaire on knowledge of healthy foods (70.0±9.2 versus 71.3±10.0 for pretest and posttest, respectively; P<0.05). Improvements in healthy eating habits were also detected: higher frequency of consumption during a week of white meat (1 [1–2] versus 2 [1–2]; P=0.01), eggs (1 [1–1] versus 1 [1–2]; P=0.01], and legumes (1 [0–1] versus 1 [1–2]; P=0.03) and lower frequency of consumption of sugar-containing packaged snacks (1 [0–1] versus 0 [0–1]; P=0.009). Most of the participants found the game easy to use and clear in its content. Half of the participants found the game interesting. Conclusions: Our study shows that “Gustavo” is a promising tool for health education, in schools or in other environments. Limitations of the study and future directions are discussed.
