Abstract

Objective: To examine the independent association of household food insecurity (HFI) with sleep duration and quality in a nationally representative cross-sectional survey of adults in Mexico.

Methods: We analyzed data from ENSANUT-2012. We assessed the association between HFI and self-reported sleep duration and quality among 11,356 adults using weighted multinomial and binomial logistic regression. The Latin American and Caribbean Food Security Scale (ELCSA) was used to categorize food security level as secure (25.5%), mild HFI (43.7%), moderate HFI (19.0%), or severe HFI (11.8%).

Results: Overall, 20.8% of individuals reported getting less than the recommended 7-8 hours of sleep/night, 20.4% reported getting more than the recommended amount of sleep, and 20.7% reported poor sleep quality. In unadjusted analyses, severe HFI was significantly associated with getting both less than and more than the recommended amount of sleep. After adjusting for potential confounders, there remained a significant association between severe HFI and getting too little sleep (adjusted odds ratio [AOR]=1.83, 95% confidence interval [CI]=1.37-2.43). Compared with food-secure individuals, odds of poor sleep quality increased with level of food insecurity (AOR=1.27, 95% CI=1.04-1.56 for mild HFI; AOR=1.71, 95% CI=1.36-2.14 for moderate HFI; and AOR=1.89, 95% CI=1.45-2.45 for severe HFI).

Conclusions: HFI is associated with inadequate sleep duration and poor sleep quality among Mexican adults. This study adds evidence to how detrimental HFI is to the well-being of the Mexican population, increasing urgency to address HFI in Mexico.
