AbstractObjectiveTo examine the interaction between waist circumference (WC) and serum 25-hydroxyvitamin D (25(OH)D) level in their associations with serum lipids.DesignCross-sectional study. The associations of serum 25(OH)D with total cholesterol, HDL cholesterol (HDL-C), LDL cholesterol (LDL-C), LDL-C:HDL-C and TAG were examined using multiple linear regression. Effect modification by WC was assessed through cross-product interaction terms between 25(OH)D and WC categories (abdominal overweight, 80–<88 cm in females/94–<102 cm in males; abdominal obesity, ≥88 cm in females/≥102 cm in males).SettingThe US National Health and Nutrition Examination Survey waves 2001–2006.SubjectsNon-pregnant fasting participants (n 4342) aged ≥20 years.ResultsLower 25(OH)D levels were significantly associated with lower HDL-C levels as well as with higher LDL-C:HDL-C and TAG levels in abdominally obese participants, but not in abdominally overweight or normal-waist participants. In contrast, lower 25(OH)D levels were associated with lower levels of total cholesterol and LDL-C in abdominally overweight and normal-waist participants only, but this association was only partly significant. However, a significant difference in the association between 25(OH)D and the lipids according to WC category was found only for LDL-C:HDL-C (P for interaction=0·02).ConclusionsOur results from this large, cross-sectional sample suggest that the association between lower 25(OH)D levels and an unfavourable lipid profile is stronger in individuals with abdominal obesity than in those with abdominal overweight or a normal WC.

AbstractThe role of eating frequency (EF) in obesity development has been debated, and few studies have investigated Asian populations. Diet quality might affect the association between EF and obesity. Therefore, we investigated the association between EF and obesity indicators in a representative sample of Korean adults with consideration to diet quality. This cross-sectional study used data of 6951 participants aged 19–93 years (male 49·8 %, female 50·2 %) from the Fourth Korean National Health and Nutrition Examination Survey. EF was assessed using a questionnaire, and diet quality was defined as mean adequacy ratio (MAR). To explore the association between EF and obesity indicators, we used multiple linear regression analyses with and without interaction terms between diet quality and EF. EF was inversely associated with each obesity indicator, including body fat percentage (BF%), BMI and waist circumference (WC), showing a significant linear trend (P<0·001 for BF%, WC and BMI). In addition, the association between EF and each obesity indicator was significantly altered according to diet quality (Pvalue of the interaction term EF×diet quality=0·008 in the regression model for BF%, <0·001 for BMI and 0·043 for WC). In the stratified analyses according to diet quality, EF had a significant inverse association with BF%, WC and BMI in the high diet quality groups, but not in the low diet quality groups. This study suggests that EF is inversely associated with the obesity indicators when diet quality is high, but not when it is low in Korean adults.
