Nigerian Smoking & Health Dataset

Dataset Description

A research-grade synthetic dataset modeling smoking behaviors and health outcomes in Nigeria, using probabilistic relationships derived from peer-reviewed epidemiological studies. This dataset reflects Nigeria-specific disease prevalence, genetic factors, and environmental exposures that are often absent from Western-centric health datasets.

Key Features

3,900 records representing adult Nigerians (18-70 years)
12 variables including demographics, behavioral risks, genetic factors, and health outcomes
Evidence-based distributions from WHO, Nigerian National Health Surveys, and medical literature
Conditional probabilities modeling real disease interactions (e.g., malaria × sickle cell × smoking)
Regional variations across Nigeria's six geopolitical zones
Urban/rural differences in disease burden and risk factors

Research Value & Probabilistic Methodology

Why This Dataset is Different

Most publicly available health datasets:

❌ Use Western populations (not representative of African health patterns)
❌ Generate features independently (ignore biological relationships)
❌ Lack Nigerian-specific conditions (malaria, sickle cell disease)
❌ Have unrealistic smoking rates for Nigeria (49% vs actual 5%)

This dataset:

✅ Population-specific prevalence: Smoking 5% (vs 49% in original), matching WHO Nigeria data
✅ Conditional probabilities: Hemoglobin depends on sickle cell status, malaria, and sex
✅ Nigerian disease burden: Includes sickle cell (24% carriers), malaria (endemic), hypertension (32%)
✅ Geographic heterogeneity: Urban Lagos ≠ Rural Sokoto
✅ Evidence-based: Every parameter traceable to published research

Probabilistic Relationships Modeled

Example 1: Hemoglobin Level

Hemoglobin = Baseline(sex) 
             × SickleCellMultiplier(genotype)
             - MalariaEffect(recent_infection)
             - AgeDecline(age)

Result:

Normal male (AA, no malaria): ~14.5 g/dL
Sickle cell disease (SS): ~7-8 g/dL (severe anemia)
Recent malaria + normal genetics: ~10-11 g/dL (acute anemia)
SS + malaria: ~6 g/dL (life-threatening, requires hospitalization)

Example 2: Heart Rate

HeartRate = Baseline 
            + AnemiaCompensation(hemoglobin)
            + SmokingEffect(smoker)
            + MalariaFever(acute_infection)

Result: Lower hemoglobin → Higher heart rate (physiological compensation)

Example 3: Smoking Probability

P(Smoker | sex, age, region, location) = 
    BaseRate(sex, age_group) × RegionalModifier(region, urban_rural)

Result:

Male, 35-54, urban Lagos: ~8% smoking rate
Female, any age, any location: ~1% smoking rate (cultural factors)
Overall: 4.7% (matches WHO Nigeria 2023 data)

Note: This dataset is fully anonymized with no PII.

Example showing probabilistic relationships:

Second record: SS genotype → Very low hemoglobin (6.3 g/dL)
Low hemoglobin → Compensatory high heart rate (118 bpm)
This demonstrates the conditional disease relationships in action

Disease Interactions Modeled

1. Sickle Cell × Malaria (Protective Effect)

Biological Relationship: Sickle cell trait (AS) provides 50-90% protection against severe malaria.

Modeling: AS individuals in high-malaria regions have lower severe malaria rates.

Research: Taylor et al. (2012), Science, "Protective effect of sickle cell hemoglobin"

2. Malaria → Anemia → Tachycardia

Biological Pathway: Malaria destroys red blood cells → Low hemoglobin → Heart compensates by beating faster

Modeling:

Recent malaria → Hemoglobin -2.5 g/dL → Heart rate +15 bpm

Research: Ezeamama et al. (2005), Malaria Journal, "Functional significance of anaemia in malaria"

3. Smoking × Sickle Cell Disease (Avoidance)

Clinical Reality: Sickle cell patients avoid smoking (triggers crises)

Modeling: P(Smoker | SS genotype) = 0.01 (vs 5% baseline)

Research: Platt et al. (1994), NEJM, "Mortality in sickle cell disease"

4. Hypertension × Age × Location

Epidemiological Pattern: Urban elderly have highest hypertension rates

Modeling:

P(HTN | age 60+, urban) = 0.38 × 1.8 = 68%
P(HTN | age 20-34, rural) = 0.28 × 0.5 = 14%

Research: Nigerian National NCD Survey (2019)

Use Cases

1. Machine Learning & AI

Classification: Predict smoking status from health metrics
Regression: Estimate hemoglobin from demographics and exposures
Feature importance: Understand which factors drive health outcomes
Causal inference: Test interventions (e.g., malaria reduction → anemia improvement)

2. Epidemiological Research

Disease burden estimation: Model population health needs
Risk factor analysis: Quantify smoking, malaria, sickle cell effects
Intervention targeting: Identify high-risk subgroups
Comparative studies: Nigeria vs other African countries

3. Healthcare Policy

Resource allocation: Where to deploy healthcare services
Screening programs: Target sickle cell or hypertension screening
Prevention campaigns: Design culturally appropriate anti-smoking campaigns
Health system planning: Estimate need for blood transfusions, antimalarials

4. Education

Biostatistics teaching: Realistic data for analysis exercises
Epidemiology courses: Demonstrate disease interactions
Global health: Compare Nigerian vs Western disease patterns
Data science: Practice with complex, real-world feature relationships

Limitations

1. Synthetic Data

Not collected from real patients (computer-generated)
Individual records are not real people
Population-level statistics match research, but individual variation is simulated

2. Simplified Disease Models

Real biology is more complex than modeled
Other diseases (TB, HIV, diabetes) not included
Medication effects not modeled (e.g., hydroxyurea for SCD)

3. Static Snapshot

Represents one point in time
No longitudinal follow-up or disease progression
Seasonal variations not explicitly modeled

4. Missing Factors

Socioeconomic status (SES)
Education level
Healthcare access and insurance
Detailed dietary information
Physical activity levels

5. Regional Aggregation

Geopolitical zones aggregate multiple states
Within-zone variation exists but not modeled
Urban/rural is binary (peri-urban not distinguished)

Ethical Considerations

Synthetic Data Benefits

✅ Fully anonymized - No personally identifiable information (PII) ✅ No privacy concerns (no real patients) ✅ No informed consent needed ✅ Can be shared openly ✅ Useful for testing algorithms before real patient data ✅ Safe for educational and research use

Responsible Use

⚠️ Do not use for clinical decision-making (synthetic data) ⚠️ Validate models on real data before deployment ⚠️ Acknowledge limitations in publications ⚠️ Cite research sources (see RESEARCH_SOURCES.md)
