Table 3 Association between serum Zn status and basic physical functioning difficulty stratified by sex, 2011–14 NHANES survey data

From: Association between serum zinc levels and basic physical functioning: secondary data analysis of NHANES 2011–14

Multivariable-adjusted† odds ratio with 95% confidence interval
  Male
(physical difficulty: yes = 133, No = 428); aOR (95% CI)
Female
(physical difficulty: yes = 150, No = 425); aOR (95% CI)
Serum Zn tertile
High vs. low Zn group 0.43 (0.25–0.76)* 1.42 (0.76–2.65)
Middle vs. low Zn group 0.73 (0.35–1.52) 2.67 (1.58–4.50)*
  1. Note: Model was adjusted for age, weight (obesity vs. normal, overweight vs. normal, underweight vs. normal), race/ethnicity, education, health insurance, drinking status, smoking status, physical activity, diabetes, serum albumin (gm/dL), and blood hemoglobin (gm/dL)
  2. * Indicates a significant association with p values < 0.05
  3. † Variables except age, hemoglobin, and serum albumin level were dichotomized as 1 = yes, 0 = no (baseline)
  4. Abbreviations: aOR = adjusted odds ratio; CI = confidence interval
