Atherogenic indices and prehypertension in obese and non-obese children

We evaluate the relationship between different lipoproteins and atherogenic indices with pre-hypertension in 297 obese and 942 non-obese children with Tanner stage 1 enrolled in a multicentre, community-based cross-sectional study. Height, weight, fasting glucose and insulin levels, total cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol (LDL-c), non-HDL-c, LDL/HDL-c, triglycerides/cholesterol and total cholesterol/HDL-c ratios were measured. Mean age was 8.4 ± 1.2 years; pre-hypertension was identified in 104 (8.4%) participants, 46 (15.5%) obese and 58 (6.1%) non-obese children. The pre-hypertensive non-obese children show a high proportion of family history of hypertension (41.6 and 24.7%, p = 0.002) and elevation of insulin at a relatively low body mass index. The triglycerides:HDL-c ratio, but not other lipoproteins or atherogenic indices, was associated with pre-hypertension in obese (1.15, 95% confidence intervals 1.06–1.26) and non-obese children (1.38 95% confidence intervals 1.22–1.57). The triglycerides:HDL-c ratio is related to pre-hypertension in children; the family history of hypertension seems to be a risk factor in developing pre-hypertension.
