- The ADIPOQ gene has been implicated in the etiology of hypertension. However, the results have been inconsistent. In this study, a meta-analysis was performed to assess the associations of ADIPOQ polymorphisms with hypertension risk among the Chinese. Published literature from PubMed, CNKI and Wanfang Data were retrieved. Pooled odds ratio (OR) with 95 % confidence interval (CI) was calculated using fixed- or random-effects model. Six studies (1,812 cases and 2,631 controls) for rs2241766 polymorphism and four studies (1,449 cases and 2,175 controls) for rs1501299 polymorphism were identified. A marginally significant association was observed for rs2241766 polymorphism under recessive genetic model (GG vs. GT+TT: OR = 1.22, 95 % CI 1.01–1.48) and for rs1501299 polymorphism under heterogeneous co-dominant model (TG vs. GG: OR = 0.86, 95 % CI 0.75–0.99) and dominant model (TT+TG vs. GG: OR = 0.85, 95 % CI 0.74–0.98). In addition, under other genetic models, there was no significant association for rs2241766 polymorphism (GG vs. TT: OR = 1.20, 95 % CI 0.98–1.48; GT vs. TT: OR = 0.97, 95 % CI 0.85–1.10; GG+GT vs. TT: OR = 1.01, 95 % CI 0.90–1.15) and for rs1501299 polymorphism (TT vs. GG: OR = 0.82, 95 % CI 0.62–1.08; TT vs. TG+GG: OR = 0.87, 95 % CI 0.66–1.14). However, the associations above were not robust by sensitivity analysis. The present meta-analysis indicated the limited evidence of the significant associations between ADIPOQ gene polymorphisms and hypertension susceptibility among the Chinese.
