BackgroundThe association of obesity with adiponectin gene has been reported in different populations with various inconsistencies. Data from Nigeria is very scanty on the association. AimWe investigated possible associations of adiponectin gene (ADIPOQ) single nucleotide polymorphisms (SNPs) rs2241766 (+45T>G in exon 2), rs266729 (−11377C>G in promoter) and rs1501299 (+276G>T in intron 2) with body mass index (BMI), waist circumference (WC) and hip circumference (HC), in our cross-sectional study. Subjects and methodsSNPs in ADIPOQ were genotyped in 107 subjects (81 females, 26 males; mean age 22.2years) by Sequenom MassARRAY. Notably, rs2241766 was removed for not reaching Hardy-Weinberg equilibrium. BMI was calculated (kg/m2) while WC and HC were measured using standard procedures ResultsLinear regression showed that variant rs1501299 was not associated with BMI, WC or HC but rs266729 was associated with increased measures of obesity involving BMI (recessive model; beta coefficient [β], 12.85; 95% confidence interval [CI], 6.47, 19.24, codominant model; GG, β, 13.08; 95% CI, 6.71, 19.46, GC, β, 1.04; 95% CI, −0.60, 2.68 and log-additive model; β, 2.117; 95% CI, 0.55, 3.68), WC (recessive model; β, 22.17; 95% CI, 7.11, 37.23 and codominant model; GG, β, 21.857; 95% CI, 6.74, 36.98, GC, β, −1.459; 95% CI, −5.34, 2.43) and HC (recessive model; β, 33.56; 95% CI, 15.41, 51.70, codominant model; GG, β, 34.171; 95% CI, 16.04, 52.30, GC, β, 2.771; 95% CI, −1.79, 7.34 and log-additive model; β, 5.466; 95% CI, 1.14, 9.80). ConclusionThis study in young Nigerian adults confirmed previously reported association of SNP −11377C>G with obesity measures in other populations.
