Are serum leptin levels predicted by lipoproteins, vitamin D and body composition?

Table 2 Correlation of metabolic and biochemical factors with serum log leptin according to gender distribution

Gender	n	BMI (kg/m2)	Waist circumference (cm)	Total body fat %	Total body water %	Muscle mass (kg)	BMR (kcal)	Bone mass (kg)	Total cholesterol (mg/dL)	Mean HDL(mg/dL)	Mean non-HDL(mg/dL)	Log 25OHD (ng/mL)
Male	74	0.2561	0.2561	0.472	-0.3312	-0.4992	-0.018	-0.206	-0.053	-0.139	-0.023	-0.4792
Female	93	0.3772	0.3622	0.3222	-0.2712	0.02	-0.332b	0.247a	-0.169	-0.176	-0.135	-0.102

¹Correlation is significant at the 0.05 level (2-tailed);

²Correlation is significant at the 0.01 level (2-tailed). Univariate analysis was conducted and variables that had significant association with leptin in univariate analysis at P < 0.2 were considered in multivariable analysis. Coefficients (r) and P values are calculated using Pearson's correlation analysis. P-value less than 0.05 was considered as significant and < 0.001 as highly significant. BMI: Body mass index; BMR: Basal metabolic rate; 25OHD: 25-hydroxy vitamin D; HDL: High density lipoprotein.
