Hypertriglyceridaemia either in isolation or in combination with abdominal obesity is strongly associated with atherogenic dyslipidaemia in Asian Indians.

AIM

To assess the prevalence of isolated hypertriglyceridaemia (iHTG) and hypertriglyceridaemic waist phenotype (HTWP) in urban adult Asian Indian population and to study their associations with atherogenic dyslipidaemia.

METHODS

Data of an epidemiological survey (n=2117, M:F 1007:1110) was used. Prevalences of iHTG (fasting triglycerides (TG) ≥ 1.7 mmol/l) and HTWP (waist circumference male ≥ 90 cm and female ≥ 80 cm and TG ≥ 1.7 mmol/l), were assessed. Their prevalences in relation to glucose intolerance were also studied. Associations of iHTG and HTWP with the occurrence of atherogenic dyslipidaemia indicated by elevated LDL-C/HDL-C ratio of ≥2.5 were assessed using multiple logistic regression analyses.

RESULTS

iHTG, and HTWP were present in 13.4% and 17.8% respectively. Prevalence of HTWP was significantly higher among women. Prevalence of HTWP progressively increased with glucose intolerance. Nearly 60% of the subjects with iHTG or HTWP had atherogenic dyslipidaemia and prevalence was similar in both groups.

CONCLUSIONS

Hypertriglyceridaemia, present either as iHTG or HTWP was strongly associated with atherogenic dyslipidaemia. Dyslipidaemia occurred more frequently in glucose intolerance since the prevalence of both forms of hypertriglyceridaemia increased with glucose intolerance.
