The purpose of the Traditions study was to examine the influence of cultural immersion on
willingness to try fruits and vegetables among children, 3-12 y, in Guam. The primary
objective of this study was to examine willingness to try fruits and vegetables and fruit
and vegetable intake among children attending three existing summer camp programs: a
cultural immersion camp, a university day camp, and a recreational sports camp. The primary
hypothesis was that children attending the cultural immersion camp would have higher
willingness to try fruits and vegetables (WillTry score) and a higher intake of fruits and
vegetables compared to children attending both, the university day camp and recreational
sports camp, without cultural immersion.
A pre-post, quasi-experimental design was used to evaluate 3 summer camps with different
exposure levels of cultural immersion. High, moderate, and zero (cultural) exposure was
provided by a cultural immersion camp (CIC), a university-based day camp (UDC), and a
recreational sports camp (RSC), respectively. CIC delivered 4 culturally adapted nutrition
lessons within the context of Chamorro cultural traditions as part of the cultural immersion
camp activities. The UDC delivered the same lessons within a physiology framework. The RSC
was without nutrition lessons and cultural immersion. Children 3-12 years old registered in
any of the three summer camp programs were eligible to participate. Data collection was
primarily administered at two assessment periods: before (± 2 weeks) and after (± 1 week)
each summer camp program. Children's willingness to try fruits and vegetables, the primary
outcome, was assessed with the interview-administered Adapted WillTry tool. The secondary
outcome was fruit and vegetable intake as servings/day in the CIC to UDC only. Fruit and
vegetable intake was assessed using the mobile food record (mFR), which is an app running on
an iPod Touch based on the technology assisted dietary assessment (TADA) protocols. Outcomes
examined Adapted WillTry post-scores for local novel and local common fruits and vegetables
and fruit and vegetable servings/day using multivariate regression models adjusting for the
relevant pre-score, sex, age, ethnicity, dose, BMI percentile, and parent's cultural
affiliation. Therefore, additional measures like sociodemographic information, anthropometry
(i.e. heights and weights), and parent's cultural affiliation were collected to account for
potential confounders.

Primary | Willingness to try local fruits and vegetables measured by the Adapted WillTry tool. | The Adapted WillTry tool measures children's willingness to try FV and was previously validated for children 3-11 years old in Guam. The Adapted WillTry has 3 distinct scales of FV: local novel, local common, and imported. The scores for each scale ranged from 1 to 3, i.e., least to most willing to try. The Adapted WillTry administration and scoring methods have been described previously. | 4 weeks | No |
Secondary | Fruit and vegetable intake measured using the mobile food record | FV intake was assessed using the mobile food record (mFR) running on iOS7.1.2 on an Apple iPod touch. Only participants in CIC and UDC were asked to use the mFR due to a limited number of iPods. Children used the mFR for two consecutive days to capture before and after images of all eating occasions. Instructions on how to use the mFR included taking a practice image of plastic food replicas with a fiducial marker (FM). The FM functioned as a color reference and volume marker of the food. Children were loaned the mFR and 2-4 FMs. When the children returned the mFR, researchers asked children to assist with identifying food items that were indistinguishable, e.g., opaque containers, occluded foods; and to recall foods at eating occasions not captured as an image. | 4 weeks | No |
