Background

Food insecurity, or the limited or uncertain access to food resulting from inadequate financial resources, is associated with a higher prevalence of chronic disease in adulthood. Little is known about these relationships specifically in young adulthood, an important time for the development of chronic disease.

Objective

To determine the association between food insecurity and chronic disease including diabetes, hypertension, obesity, and obstructive airway disease in a nationally representative sample of US young adults.

Design

Cross-sectional nationally representative data collected from Wave IV (2008) of the National Longitudinal Study of Adolescent to Adult Health was analyzed using multiple logistic regression models.

Participants

US young adults ages 24-32 years old MAIN MEASURES: Food insecurity and general health; self-reported diabetes, hypertension, hyperlipidemia, "very overweight," and obstructive airway disease; measured obesity derived from body mass index; and inadequate disease control (hemoglobin A1c ≥ 7.0%, blood pressure ≥ 140/90 mmHg) among those with reported diabetes and hypertension.

Key results

Of the 14,786 young adults in the sample, 11% were food insecure. Food-insecure young adults had greater odds of self-reported poor health (2.63, 95% confidence interval (CI) 1.63-4.24), diabetes (1.67, 95% CI 1.18-2.37), hypertension (1.40, 95% CI 1.14-1.72), being "very overweight" (1.30, 95% CI 1.08-1.57), and obstructive airway disease (1.48, 95% CI 1.22-1.80) in adjusted models compared with young adults who were food secure. Food insecurity was not associated with inadequate disease control among those with diabetes or hypertension.

Conclusions

Food insecurity is associated with several self-reported chronic diseases and obesity in young adulthood. Health care providers should screen for food insecurity in young adults and provide referrals when appropriate. Future research should evaluate the impact of early interventions to combat food insecurity on the prevention of downstream health effects in later adulthood.
