About This Data

This page presents aggregated, anonymised data from our Yale Food Addiction Scale (YFAS 2.0) test. The information displayed is based on 6439 individual calculator completions.

Important Note: This data represents a self-selecting cohort of individuals who actively sought out and completed our YFAS calculator. As such, it is not representative of the general population and should not be interpreted as prevalence data for food addiction in the broader community.

Diagnosis Category Distribution

The YFAS 2.0 classifies results into four categories based on symptom count and clinical significance: No Food Addiction, Mild, Moderate, and Severe Food Addiction.

Distribution of Diagnosis Categories

Diagnosis Severity by Country

Distribution Pattern

The diagnosis distribution shows a striking bimodal pattern - people either report no food addiction (53.1%) or severe food addiction (37.2%), with mild and moderate categories combined representing only 9.8% of completions. This suggests food addiction may function more as a threshold phenomenon than a gradual spectrum. The YFAS diagnostic structure requires both clinical significance (clinically significant distress or impairment) and multiple symptoms for a diagnosis, which may contribute to this pattern.

Geographic Variation

Severe food addiction rates vary substantially by country:

  • India: 46.5% severe food addiction (n=129)
  • Norway: 25.7% severe food addiction (n=101)

This represents a 1.8-fold difference in severe food addiction rates (p < 0.001). These top 10 countries represent 4,747 completions.

Note:

Geographic differences may reflect cultural factors, dietary patterns, demographic composition, or help-seeking behaviours. Caution is advised when interpreting cross-country comparisons due to potential selection bias.

Symptom Count Distribution

This chart shows the distribution of symptom counts (0-11) across all calculator completions. The YFAS 2.0 measures 11 possible symptoms of food addiction.

Distribution of Symptom Counts

Distribution Pattern

The symptom count distribution reveals a zero-inflated, relatively uniform pattern. Notably, 20.6% of people report zero symptoms, followed by a sharp decline to 8.6% with exactly one symptom. However, for people reporting 2-11 symptoms, the distribution is remarkably flat, ranging from 6.3% to 7.8%.

Key Finding

This pattern is particularly striking because:

  • People are evenly distributed across symptom counts 2-11 (approximately 10% in each category)
  • There is no clustering at either low or high symptom counts
  • This contradicts the bimodal diagnosis pattern observed in diagnosis categories (mostly 'No FA' or 'Severe FA')

What This Reveals

The contrast between uniform symptom distribution and bimodal diagnosis distribution demonstrates how the YFAS diagnostic structure transforms symptom counts into clinical categories. Many people with 2-5 symptoms are classified as 'No Food Addiction' due to lacking clinical significance (clinically significant distress or impairment), while those with 6+ symptoms are more likely to meet both symptom and clinical significance thresholds, resulting in 'Severe Food Addiction' diagnoses. This threshold effect creates the bimodal pattern in diagnoses despite the underlying symptom distribution being relatively uniform.

The Zero-Symptom Peak

The 20.6% of completions with zero symptoms likely represents individuals exploring the assessment out of curiosity, health professionals familiarizing themselves with the tool, or people seeking confirmation that their eating patterns are within typical ranges.

Note: responses collected before the criterion-7 (withdrawal) scoring fix were scored under a different definition of that criterion. Figures from before and after the fix are not directly comparable. Read more about this change.

Distribution Across Demographics

These charts show both the number of completions and average symptom count for each demographic group. The dual y-axes allow comparison of population size (left) and symptom severity (right).

Sex Distribution

Key Insight: Females show both higher participation (57.2%) and higher average symptom counts (5.1 vs 4.2, p < 0.001). This suggests gender may play a role in food-related behaviours.

Age Distribution

Key Insight: Younger adults (under 18) show the highest average symptom count (5.7) and clinical significance rate (63.9%), with symptoms generally decreasing with age. The 65-74 age group shows the lowest average (3.8 symptoms).

BMI Category Distribution

Key Insight: A very strong linear relationship exists between BMI and symptom count (p < 0.001). Obese Class III shows the highest average (6.9 symptoms) with 66.3% clinical significance, while those with normal BMI show the lowest (3.4 symptoms) with 36.8% clinical significance. This 3.5-symptom difference makes BMI the strongest demographic predictor.

Clinical Significance Comparison

This chart compares the percentage of people with clinical significance (distress/impairment) across all demographic groups. Higher percentages indicate groups at greater risk.

Clinical Significance Across Demographics

Diagnosis Severity Distribution

These stacked bar charts show the percentage of people in each diagnosis category (No Food Addiction, Mild, Moderate, or Severe Food Addiction) across demographic groups. Each bar represents 100% of the population within that demographic category, allowing direct comparison of severity patterns.

Diagnosis Categories by Sex

Key Insight: Females show notably higher rates of severe food addiction (40.9%) compared to males (27.5%) (p < 0.001), while males are more likely to show no food addiction (67.1% vs 48.2%). This pattern is consistent with research on eating disorders and may reflect biological factors (hormonal influences on appetite), psychological factors (emotion regulation, body image), or social factors (cultural pressures around food and body).

Diagnosis Categories by Age

Key Insight: A clear age-related pattern emerges (p < 0.05): younger adults (under 18) show the highest rate of severe food addiction (51.2%), while older adults (75+) show the lowest rate (16.7%). This 34.5-percentage-point difference suggests that younger adults face greater risk, potentially due to factors like higher stress levels, different food environments, social media influences, or less developed coping strategies. The pattern may also reflect that older adults have developed better self-regulation over time.

Diagnosis Categories by BMI

Key Insight: BMI shows the strongest and most linear relationship with diagnosis severity (p < 0.001). Obese Class III individuals show severe food addiction at 55.8%, more than double the rate in those with normal BMI (24.1%). Each step up in BMI category shows progressively higher severe FA rates, suggesting a dose-response relationship. Meanwhile, those with normal BMI show no food addiction 65.4% of the time compared to just 35.1% in Obese Class III. This pattern indicates a powerful association between weight status and food-related behaviours.

Interpreting These Patterns

⚖️ BMI Correlation

BMI shows the strongest correlation with food addiction symptoms, with over double the symptom count in higher BMI categories. Those with higher BMI categories consistently show higher symptom counts and clinical significance rates, suggesting a strong bidirectional relationship between weight status and food-related behaviours.

📉 Age Trend

Symptom counts decrease with age, with young adults (18-24) showing the highest rates. This may reflect differences in eating patterns, stress levels, food environment, or biological factors across life stages. The decline with age could indicate improved coping strategies or changing food relationships over time.

⚧️ Sex Differences

Females show approximately 22% higher symptom counts than males. This pattern is consistent with research on eating disorders and may reflect biological factors (hormonal influences on appetite and reward), psychological factors (emotion regulation, body image concerns), or social factors (cultural pressures, different food relationships).

📊 Combined Risk

Risk factors compound: under 18, young females show the highest symptom counts. Understanding these intersections helps identify the most vulnerable populations and can inform targeted prevention and intervention strategies. Multiple risk factors appearing together may indicate cumulative effects that warrant particular attention.

Data Quality & Statistical Significance

Demographic information was provided voluntarily by participants:

  • Age: 48.2% of participants provided age information
  • Sex: 55.6% of participants provided sex information
  • BMI: 51.5% of participants provided height/weight for BMI calculation

Charts exclude "not specified" categories to focus on interpretable patterns. The substantial sample sizes provide reliable insights into demographic trends within this self-selecting population.

Statistical Note: P-values (shown in parentheses where applicable) indicate the statistical significance of observed differences. For group comparisons (e.g., males vs females), p < 0.05 is used as the significance threshold. For trend tests across ordered categories with small sample sizes (e.g., age groups, BMI categories), p < 0.10 is used to account for reduced statistical power. P < 0.01 indicates strong evidence, and p < 0.001 indicates very strong evidence for the observed pattern.

Note: responses collected before the criterion-7 (withdrawal) scoring fix were scored under a different definition of that criterion. Figures from before and after the fix are not directly comparable. Read more about this change.

Criterion 7: before vs. after the scoring fix

Comparison shown now that enough post-fix responses have been collected. Figures are ordered to follow the mechanism: criterion 7 changed first, and because symptomCount (which drives clinical significance) contains criterion 7, the symptom-count distribution and clinically-significant percentage move as a consequence.

Methodology Notes

The Yale Food Addiction Scale 2.0 is a validated tool to assess food addiction based on DSM-5 criteria for substance use disorders. It consists of 35 questions about eating behaviors over the past 12 months.

Key Metrics Explained:

  • Symptom Count: The number of DSM-5 criteria met (0-11).
  • Clinical Significance: Whether food-related problems cause significant distress.
  • Diagnosis Categories:
    • No Food Addiction: Clinical significance not present, or fewer than 2 symptoms.
    • Mild Food Addiction: Clinical significance present + 2-3 symptoms.
    • Moderate Food Addiction: Clinical significance present + 4-5 symptoms.
    • Severe Food Addiction: Clinical significance present + 6 or more symptoms.

Data Privacy:

All data presented here is anonymised and aggregated. No personally identifiable information is collected or displayed. Location data is derived from anonymised IP addresses and is only shown when sufficient entries exist to protect privacy.

Data Filtering Methodology:

To ensure the data presented here reflects genuine user interactions with the calculator and is suitable for analysis, we apply several filtering criteria before including submissions in the aggregated statistics:

  • Speed Checks: Submissions completed unrealistically quickly (e.g., faster than a human could reasonably read and answer the questions) are automatically removed as likely automated entries.
  • Duplicate Prevention: Measures are in place to detect and exclude unintended duplicate submissions from the same user, such as those resulting from accidental double-clicks or form re-submissions.
  • Automated Submission Detection: We employ techniques (such as analysing submission patterns and utilizing anti-bot measures) to identify and filter out submissions from bots or automated scripts rather than human users.
  • Completion Requirements: Only submissions where all necessary questions in the questionnaire were answered are included in the aggregate data.

These data quality control steps help maintain the integrity and relevance of the dataset used for generating the statistics displayed.
