Food Insecurity Among Older Adults: 10-Year National Trends and Associations with Diet Quality.

ABSTRACT:

Background/objectives

Food insecurity has emerged as a critical health issue for older adults. Food insecurity has been shown to disrupt healthy eating patterns, but these associations have not been widely studied among older adults. The objectives of the present study were to: (1) examine national trends in food insecurity across a 10-year period, and (2) evaluate the associations between food insecurity and multiple diet quality indices in a recent and nationally representative sample of adults aged 60 or older.

Design

Cross-sectional analysis of the 2007-2016 National Health and Nutrition Examination Surveys.

Setting

Nationally representative sample of the United States.

Participants

The analytic sample was comprised of 5,097 adults aged 60 or older, with household incomes at or below 300% of the federal poverty level.

Measurements

Household food security was measured using the 18-item US Household Food Security Survey Module. Diet was assessed using two 24-hour dietary recalls. Multivariate linear and logistic regression models examined the associations between household food security and three evidence-based diet quality indices, adjusting for sociodemographic and health characteristics.

Results

Across the 10-year period, food insecurity increased significantly from 5.5% to 12.4% among older adults; this increase was more pronounced among lower-income older adults. From the linear regression models, food insecurity was associated with lower scores on the Healthy Eating Index (β = -1.90, 95% confidence interval (CI) = -3.70, -0.09), the Alternate Healthy Eating Index-2010 (β = -1.47, 95% CI = -2.51, -0.44), and the Mediterranean Diet Score (β = -0.54, 95% CI = -1.06, -0.01) after multivariate adjustment. Further adjustment for the presence of chronic medical conditions did not attenuate these results.

Conclusion

Food insecurity is associated with lower overall diet quality among older adults, supporting the need for clinical efforts to identify those at risk of food insecurity and public health efforts to alleviate food insecurity and promote healthy eating behaviors among older adults.

Project description:ImportanceFood insecurity is a pervasive public health issue in the US that is associated with greater body weight.ObjectiveTo examine national trends in food insecurity among US adults from 1999 to 2016 according to surrogate measures of adiposity (body mass index [BMI] and waist circumference [WC]).Design, setting, and participantsThis cross-sectional study analyzed nationally representative data obtained from nine 2-year cycles (1999 to 2000 through 2015 to 2016) of the National Health and Nutrition Examination Survey in the US. The sample comprised adult survey participants aged 20 years or older. Data analyses were performed from July 1, 2019, to March 31, 2020.Main outcomes and measuresThe primary outcome was food insecurity. Data on BMI (calculated as weight in kilograms divided by height in meters squared) were categorized as follows: normal weight (BMI, <25), overweight (BMI, 25-29.9), and obese (BMI, ≥30). Data on WC were categorized as follows: less high risk (men: ≤102 cm; women: ≤88 cm) or high risk (men: >102 cm; women: >88 cm). Food insecurity prevalence by adiposity was further analyzed using key demographic characteristics, including sex and race/ethnicity (non-Hispanic White, non-Hispanic Black, Hispanic, and Other).ResultsAmong the 46 145 adults in the final sample, the mean (SD) age was 46.9 (0.2) years. Of this sample, 23 957 were women (52.0%; 95% CI, 51.6%-52.5%) and 20 825 were non-Hispanic White adults (68.8%; 95% CI, 66.6%-71.0%). The estimated prevalence of food insecurity was 18.2% (95% CI, 15.3%-21.2%) in the 2015 to 2016 cycle, a statistically significant change from 8.7% (95% CI, 7.3%-10.2%) in the 1999 to 2000 cycle. Among all adiposity categories, food insecurity prevalence significantly increased from the 1999 to 2000 cycle to the 2015 to 2016 cycle. The prevalence of food insecurity was highest in adults with obesity (22.6%; 95% CI, 19.5%-25.8%; P for trend <.001). For both men and women, food insecurity prevalence significantly increased from the 1999 to 2000 cycle (men: 8.8% [95% CI, 6.9%-10.6%]; women: 8.7% [95% CI, 7.0%-10.5%]) to the 2015 to 2016 cycle (men: 17.2% [95% CI, 14.1%-20.2%]; women: 19.2% [95% CI, 16.2%-22.2%]; P for trends <.001). For non-Hispanic White and non-Hispanic Black adults, food insecurity prevalence increased from the 1999 to 2000 cycle (non-Hispanic White: 6.0% [95% CI, 4.0%-8.0%]; non-Hispanic Black: 12.4% [95% CI, 9.6%-15.2%]) to the 2015 to 2016 cycle (non-Hispanic White: 13.0% [95% CI, 9.8%-16.3%]; non-Hispanic Black: 29.1% [95% CI, 24.2%-34.0%]; P for trends <.001). For Hispanic adults, food insecurity prevalence significantly increased in those with obesity (1999-2000: 19.1% [95% CI, 12.0%-26.1%]; 2015-2016: 37.6% [95% CI, 33.7%-41.5%]; P for trend ≤.001) and in both less-high-risk WC (1999-2000: 19.6% [95% CI, 12.8%-26.4%]; 2015-2016: 32.5% [95% CI, 27.3%-37.7%]; P for trend = .02) and high-risk WC categories (1999-2000: 19.3% [95% CI, 12.7%-25.9%]; 2015-2016: 36.7% [95% CI, 31.7%-41.7%]; P for trend <.001).Conclusions and relevanceIn this cross-sectional study, the estimated prevalence of food insecurity appeared to increase from 1999 to 2016 and across all levels of adiposity. These results suggest the need for multidisciplinary approaches to address the association between food insecurity and obesity in the US.
