Aim: The purpose of the present study was to determine the association of unhealthy dietary food items with cardiometabolic risk factors with and without sociodemographic factors.
Methods: This cross-sectional study used data available to the public from the National Health and Nutrition Survey (NHANES) 2009-2010 where unhealthy food consumption was based on responses to the Dietary Screener Questionnaire (unique to this NHANES cycle), and cardiometabolic risk factors were based on laboratory results, anthropometric measures, interview and examination questions for 2045 adults aged 20-69 and belonging to four racial/ethnic groups: 473 Mexican Americans (MA); 267 Other Hispanics (OH); 389, non-Hispanic Blacks (NHB) and 916 non-Hispanic Whites (NHW) (characterised by NHANES).
Results: A higher percent of MA, followed by OH and NHB, consumed soft drinks as compared to NHW. Consumption of fried potatoes was over 75% across groups and was associated with higher odds dyslipidaemia (high non-HDL cholesterol) in the reduced model: OR = 1.38 (1.10, 1.73), P = 0.009 and full model: OR = 1.50 (1.15, 1.96), P = 0.005. All unhealthy foods measured were consumed more often by males as compared to females.
Conclusions: Dyslipidaemia was associated with fried potato consumption and marginally with processed meats. Dietary interventions, tailored to specific populations, are needed to determine if substituting healthy foods in place of unhealthy ones will improve cardiometabolic outcomes.
