Prior analyses using 2001-2006 NHANES have shown associations between individual consumption of the most subsidized commodities (corn, soybeans, wheat, rice, sorghum, dairy and livestock) and cardiometabolic risk. Here, we re-evaluate this association during 2009-2014 to determine whether and the extent to which the associations remain.
This study included 12,629 US adults aged 18-64 years who participated in NHANES 2009-2014. We used NHANES and 4 federal databases (Food Patterns Equivalency Database, Food Intakes Converted to Retail Commodities, What We Eat in America, and National Nutrient Database for Standard Reference) to estimate grams of the subsidized commodities consumed per day and created a subsidy score, ranging from 0.0-1.0, with 0.0 indicating 0% of total energy intake came from subsidized commodities and 1.0 indicating 100% of total energy intake came from subsidized commodities. Cardiometabolic risk factors were obesity (BMI≥30 kg/m2), abdominal adiposity (waist-height ratio [WHtR]≥0.49, cut-off for tertile 1), hypertension (BP≥140/90 mmHg or use of BP lowering medication), dyslipidemia (non-HDL cholesterol≥160 mg/dL or use of lipid lowering medication), and dysglycemia (self-reported diabetes or HbA1c≥5.7%).
Among US adults, 50.8% of total calories consumed were derived from subsidized food commodities during 2009-2014. The subsidy score was positively associated with BMI, WHtR, nonHDL cholesterol, and HbA1c (p<0.05) using linear regression. Adjusting for age, sex, and race/ethnicity, adults in the highest quartile of the subsidy score had higher probabilities of obesity (prevalence ratio [PR] 1.36, 95% CI 1.19-1.55), abdominal adiposity (PR 1.35, 95% CI 1.12-1.63), and dysglycemia (PR 1.49, 95% CI 1.28-1.73) compared to adults in the lowest quartile.
Consumption of subsidized food commodities greater than or equal to half of total caloric intake continues to be associated with adverse cardiometabolic risk.
