Cross-sectional analysis of NHANES 2017-2018. Exposure: BMI categories (underweight/<18.5, normal 18.5-24.9, overweight 25-29.9, obese ≥30). Outcome: Hypertension defined as systolic ≥130 mmHg, diastolic ≥80 mmHg, or antihypertensive use. Survey weights: WTMEC2YR / 1 (single cycle). PSU: SDMVPSU. Strata: SDMVSTRA. Adjusted for age, sex, race/ethnicity, education, income, smoking, alcohol. Rao-Scott chi-square for bivariate comparisons. Analyses performed in Python with statsmodels.

Prospective cohort study using NHANES 1999-2018 with mortality follow-up through December 2019 (NHANES Public-Use Linked Mortality Files). Exposure: Diabetes defined as self-reported diagnosis, HbA1c ≥6.5%, fasting glucose ≥126 mg/dL, or diabetes medication use. Outcome: CVD mortality (ICD-10 I00-I09, I11, I13, I20-I51, I60-I69). Survival time: interview date to death or censoring. Cox proportional hazards with survey::svycoxph() in R. PH assumption tested with Schoenfeld residuals.

Cross-sectional analysis of NHANES 2017-2018. Exposure: Self-reported sleep duration (<5, 5-6, 7-8 [reference], >9 hours). Outcome: PHQ-9 total score (0-27). Depression severity: minimal (0-4), mild (5-9), moderate (10-14), moderately severe (15-19), severe (20-27). Survey-weighted linear regression adjusted for age, sex, race/ethnicity, income, education, BMI, physical activity, smoking, and chronic conditions. Analyses use WTMEC2YR with PSU SDMVPSU and strata SDMVSTRA.
