Vitamin B Intake and Hypertension Subtypes Analysis from NHANES 1999-2023

A cross-sectional dataset analyzing associations between dietary intake of thiamine, riboflavin, and niacin and hypertension subtypes. The data spans twenty-five years from 1999 to 2023 and was created by Siqi Ma. It likely contains disaggregated nutrient intake from food and supplement sources alongside clinical assessment data.

Use Cases

• Investigating dose-response relationships between riboflavin intake and systolic-diastolic hypertension risk based on the described logistic regression results
• Analyzing potential threshold effects in vitamin intake on hypertension subtypes based on the described inflection point near 6 mg/day
• Studying confounding effects of covariates like age and comorbidities on associations between B vitamins and isolated systolic hypertension
• Conducting subgroup analyses to explore interactions between vitamin intake and factors like smoking status, gender, and BMI

Strengths

• Data covers a twenty-five-year time range from 1999 to 2023
• Analysis disaggregates nutrient intake into 'food sources' and 'supplement sources'
• Statistical methods include multivariable logistic regression, propensity score weighting, and likelihood ratio tests

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Description metadata is limited; actual data quality requires manual inspection after download
