Summary: A new cross-sectional study reports that low dietary intake of omega-3 fatty acids is linked to increased ADHD symptoms among Palestinian early adolescents. The researchers found that socioeconomic disparities—particularly limited access to omega-3–rich foods such as fish, nuts and seeds—worsen attention and behavioral difficulties. These findings point to nutrition as a practical, low-cost public health approach to help manage ADHD in developing and conflict-affected settings.
Even after accounting for household income, parental education and employment, omega-3 deficiency remained a significant predictor of symptom severity. The research highlights the potential value of targeted nutrition strategies—like school meal programs and caregiver education—to support cognitive and behavioral health where clinical resources are limited.
Key Facts
- Nutritional link: Adolescents with lower omega-3 intake had higher ADHD symptom scores.
- Socioeconomic impact: Financial and educational disparities influenced dietary quality and ADHD risk.
- Public health value: Affordable interventions such as school nutrition programs may help reduce ADHD symptoms.

Attention-deficit/hyperactivity disorder (ADHD) symptoms are shaped by socioeconomic and dietary factors in regions affected by conflict and resource constraints, according to a new study examining a non-Western population.
The study specifically found that lower intake of omega-3 fatty acids was significantly associated with higher ADHD symptom scores among Palestinian adolescents, consistent with prior research from Western settings. Omega-3 fatty acids—particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)—are essential for brain development and cognitive functioning. Because the human body cannot synthesize these fats, they must be obtained from the diet through foods like fish, nuts and seeds or via fortified products.
ADHD affects well over 5% of children and early adolescents worldwide. While much of the existing literature on omega-3 and ADHD has focused on younger children in Western countries, this study fills an important gap by examining early adolescents (ages 10–12) in Palestine, a context shaped by economic hardship and conflict-related constraints on food availability.
Led by Professor Omar Almahmoud at Birzeit University in Ramallah, Palestine, the research surveyed 211 early adolescents, including 38 diagnosed with ADHD. Parents completed a culturally adapted Food Frequency Questionnaire designed to estimate consumption of omega-3–rich foods common in Palestinian diets. Researchers also collected demographic and socioeconomic data—age, gender, parental education and employment, and family income—to analyze how these factors related to dietary patterns and ADHD symptoms.
The results showed that adolescents with ADHD reported significantly lower omega-3 intake than those without ADHD, and the hyperactive/impulsive subtype had the lowest average intake. Statistical analysis indicated that higher omega-3 intake was associated with lower odds of hyperactive/impulsive symptoms. Socioeconomic indicators correlated with dietary intake, meaning that children from lower-income or less-educated households were more likely to have insufficient omega-3 consumption.
“Lower omega-3 fatty acid intake was significantly associated with higher ADHD symptom scores,” said Almahmoud. “Adolescents with insufficient omega-3 consumption showed more attention-related and behavioral difficulties than peers with adequate intake.” The authors emphasize that these findings are consistent with prior studies but extend the evidence into a non-Western, conflict-affected population.
Based on the study’s conclusions, the authors recommend public health measures that focus on improving dietary quality to support cognitive and behavioral development. Potential interventions include nutrition education for caregivers, subsidized access to omega-3–rich foods, and school-based programs that incorporate affordable sources of essential fatty acids. Such measures could offer a complementary, lower-cost approach to managing ADHD symptoms alongside clinical care, especially where access to specialized healthcare or medications is constrained.
Key Questions Answered:
A: Lower dietary omega-3 intake was strongly linked to higher ADHD symptom scores, suggesting omega-3s support attention and behavioral regulation in early adolescence.
A: Socioeconomic disparities—such as lower family income and parental education—were associated with poorer omega-3 intake, which in turn related to greater ADHD symptom severity.
A: It is among the first studies to examine the association between omega-3 intake and ADHD in a non-Western, conflict-affected adolescent population, demonstrating the broader relevance of diet-based interventions for mental health.

Abstract
Association between omega-3 fatty acid intake and ADHD symptoms among early adolescents aged 10–12 years: a cross-sectional study in Palestine
Objectives
Deficits in omega-3 fatty acids, particularly EPA and DHA, have been implicated in attention-deficit/hyperactivity disorder. These fats are essential for neurodevelopment and cognitive functioning during childhood and early adolescence. This study examined the association between ADHD symptoms and dietary omega-3 intake among Palestinian early adolescents aged 10–12 years, with attention to socioeconomic determinants.
Methods
A cross-sectional survey included 211 participants (38 with ADHD, 173 without). Parents completed a culturally adapted Food Frequency Questionnaire to estimate intake of omega-3–rich foods common in local diets. ADHD symptoms were assessed by subtype, and socioeconomic variables were recorded. Group differences and logistic regression analyses tested relationships between omega-3 intake and ADHD symptoms.
Results
Participants with ADHD reported significantly lower omega-3 intake than peers without ADHD. The hyperactive/impulsive subtype showed the lowest mean intake. Logistic regression indicated that each unit increase in estimated omega-3 intake was associated with a meaningful reduction in hyperactive/impulsive symptoms. Age, gender, parental education, parental employment and family income were significantly associated with omega-3 consumption.
Conclusions
Lower dietary omega-3 intake is associated with more severe ADHD symptoms, especially within the hyperactive/impulsive subtype. Socioeconomic disparities compound nutritional deficiencies and may negatively affect neurodevelopment and behavioral health. Public health interventions—such as school nutrition programs, caregiver education, and subsidies for omega-3–rich foods—could help support mental health and cognitive development among children and early adolescents in resource-limited and conflict-affected settings.
