Table 3 Association of low lymphocyte count (<1,500/mm3) with being underweight and restricting food intake

From: Low lymphocyte count in underweight Japanese women

  Lymphocyte count P value* Multivariate ORa (95% CI) P value
Normal (≥1,500/mm3) Low (<1,500/mm3)
Body mass index (BMI) groups
 Severely underweight 6 (60.0) 4 (40.0) 0.049 1.95 (1.07–3.56) 0.030
 Slightly underweight 10 (76.9) 3 (23.1)    
 Normal 64 (79.0) 17 (21.0)    
 Obese 10 (100.0) 0 (0.0)    
Restricted food intake group
 Restricting 6 (60.0) 4 (40.0) 0.213 3.73 (0.91–15.30) 0.067
 Not restricting 84 (80.8) 20 (19.2)    
  1. Data are expressed as frequency (%), odds ratio (OR) and 95% confidential interval (CI) of logistic regression analysis
  2. Severely underweight (BMI ≤ 17.5 kg/m2), slightly underweight (17.5 < BMI < 18.5 kg/m2), normal (18.5 ≤ BMI < 25 kg/m2), obese (BMI ≥ 25 kg/m2)
  3. * By chi-square for trend or Fisher’s exact probability test
  4. aMultivariate OR adjusted for age, restricted food intake, and BMI classification
