Introduction: Increased consumption of sugar-sweetened beverages (SSBs) is strongly associated with weight gain, dental cavities, and a higher risk of chronic diseases among adolescents. However, there is no available FFQ for the Malaysian population individually to evaluate and assess the consumption of SSBs and high-energy dense (HED) foods among adolescents. Method: A 24-hour diet recall with 30 adolescents were performed via Google Meet to identify the most common and frequent types of SSBs and HEDs foods consumed nowadays. The food checklist of SSBs and HED foods from literature review search was also provided to the participants. Experts critically reviewed each food item and provide a score for its relevancy and essentiality. Face validity were conducted among 10 adolescents to validate the developed FFQ. Results: The final FFQ consisted of 63 food items with ten categories. This FFQ showed high content validity for individual items with I-CVI ranging from 0.67 to 1.00 and overall questionnaires with S-CVI/Ave valued at 0.97. The calculation of Kappa statistic showed that this newly developed FFQ has excellent inter-rater reliability at the item level with K > 0.74 for 55 items and K = 0.57 only for 4 items. Most of the items were marked as relevant with a CVR score of 1.00. Conclusion: The findings of this study imply that the newly developed FFQ could be utilised to estimate the intake of SSB and HED foods of Malaysian adolescents.

Aims: The purpose of this review is to evaluate the social media intervention’s efficacy, as well as the intervention’s theory, model, and framework. Design: Systematic review. Data sources: Five databases- PubMed, Web of Sciences, Scopus, Science Direct and Google Scholar were searched systematically from June 18 to July 12, 2022. Methods: Predefined keywords of “social media”, “nutrition”, “behaviour” and “adolescents” were used. The inclusion criteria: (1) 10 to 24 years old participants; (2) social media or website as intervention platform; (3) intervention outcomes related to improvement in nutrition behaviour, anthropometric measures, knowledge and awareness; (4) is a randomized controlled trial, non-randomized controlled trial, cluster controlled, cohort, case control or before and after study design; (5) published in 2000 until 2022; (6) written or translated is English; and (7) conducted in Asia. Results: Review eligibility included nine studies. Three research were web- or website-based, while the other six used social media such as Facebook, WhatsApp, and LINE. Post-intervention outcomes showed significant gains, however some studies found no differences between the intervention and control groups. Conclusion: Social media is a widely accepted platform for educating adolescents about nutrition for behaviour change. However, the evidence shows that the interventions are lack of significant improvement between groups and the used of digital or technological-related theory, model and framework. This review demonstrated the progress of healthy behaviours in nutrition and health literacy among adolescents that can be spread through social network and the value of new technological techniques in managing the targeted population.
