Nutritional knowledge and habits of adolescents aged 9 to 13 years in Sharjah, United Arab Emirates: a crosssectional study

ABSTRACT

Good nutritional knowledge and behaviour among adolescents is important to avoid health problems that can continue into adulthood. This cross-sectional study aimed to provide baseline data on nutritional knowledge and eating habits of adolescents in Sharjah. Data were collected from 300 adolescents aged 9-13 years attending 4 private schools using a validated self-administered questionnaire. Most students [86%] had poor nutritional knowledge, especially in key areas nutritional terms, what constitutes healthy snacks and foods, daily nutritional requirements and components of food [e.g. fibre, fat, sugar]. Only 34% of the students had healthy eating behaviour 33% had eaten none or 1 vegetable only in the previous week, 25% had eaten unhealthy snacks 3 or more times, 19% had eaten frequently or daily at fast food outlets, and 36% had skipped breakfast frequently or daily. Culturally-specific, school-based educational interventions are warranted to build sound nutritional knowledge among adolescents and motivate the diet and behaviour changes needed to promote health throughout the lifespan
