Conditions

Key words (English): omega-3 fatty acids, LCPUFA, krill oil, cognition, academic achievement, mental well-being, eye tracking Key words (Dutch): omega-3 vetzuren, LCPUFA, krill olie, cognitie, schoolprestatie, mentale gezondheid, eye tracking

Interventions

1 years supplementation with Krill oil provided by Aker BioMarine Antarctic AS equalling almost the daily recommended amount of 450 mg of EPA/DHA intake per day.

Eligibility

Inclusion criteria

Inclusion criteria: Healthy adolescents aged 14-15 years in lower general secondary education (MAVO/VMBO).

Exclusion criteria

Exclusion criteria: Suffering from any medical disorders associated with learning deficits, such as ADHD, dyslexia, or autism.

Design outcomes

Primary

Measure	Time frame
Academic achievement: grade point average for Dutch, English, and Mathematics Cognitive performance: neuropsychological tests covering several executive functions (LDST, D2, Digit Span Forward and Backward, CST, Stroop test) Behavior: absenteeism, motivation (MSLQ), Mood (CES-D), Self-esteem (RSE)	—

Secondary

Measure	Time frame
Two types of eye tracking parameters will be calculated, namely basic parameters and paragraph-related parameters. Basic parameters are number of blinks, number of fixations, total duration of fixations, average fixation duration, average dispersion of fixation positions, average saccadic amplitude, and average saccadic velocity. Moreover, we will calculate eye tracking measures per paragraph, namely time spent on each paragraph (number and duration of fixations), time elapsed until first looking at a paragraph, and amount of times going back to a paragraph (revisits). Sleep will be assessed in a subsample. Sleep quality and quantity as measured by activPAL and questionnaires (ASHS and ASWS) will be collected.	—
