NDHS 2023–24: Timely HepB-BD in Nigeria — Analytic Dataset & Manuscript Package

NDHS 2023–24: Timely Hepatitis B Birth Dose (≤24 h) in Nigeria — Analytic Dataset & Manuscript Package

Overview.
This deposit contains the analysis-ready Stata dataset and companion materials used to quantify timely hepatitis B birth-dose (HepB-BD ≤24 hours) coverage in Nigeria using the 2023–24 Nigeria Demographic and Health Survey (NDHS). It supports national and state-level estimation and equity analyses aligned with day-zero protection goals.

What this deposit includes.

• NDHS2023_24_Analytic_HepBBD_timeliness_CMCaware.dta — de-identified, analysis-ready dataset (derived from NDHS 2023–24 public-use microdata).

• codebook.csv and VARIABLE_LIST.md — machine- and human-readable documentation of variables, types, missingness, and brief notes.

• Manuscript materials: BWHO_HepBBD_MainText.docx, BWHO_Main_Tables (1).docx, BWHO_Supplement_FINAL.docx.

• Integrity and documentation files: README.md, CITATION.cff, MANIFEST.csv, checksums.sha256, LICENSE_DATA.txt, METADATA.json.

Intended use & reproducibility.

• The dataset is survey-ready for Stata (svyset) and R (survey). Survey weights, strata, and PSU variables are preserved; consult codebook.csv for exact variable names.

• Report design-consistent point estimates with 95% confidence intervals.

• The file supports state-resolved indicators, subgroup contrasts (e.g., residence, wealth, education, place of birth, early postnatal contact), and alternative timing windows (e.g., day 0; ≤1/≤2/≤3/≤7 days) where applicable.

Denominators & definitions (to prevent bias).

• Any HepB-BD information: child has documented receipt/status of HepB-BD (denominator for “any dose”).

• Evaluable timeliness: child has precise dates allowing assessment of ≤24 h (denominator for timely/late).
  Children with non-dated “yes” are included for “any dose” but excluded from timeliness denominators.

Provenance & ethics.
This is a secondary analysis of de-identified NDHS 2023–24 public-use microdata under the DHS data-use agreement. No direct identifiers are included. Users should acknowledge the DHS Programme and the National Population Commission of Nigeria as the primary data sources.
