Household Food Insecurity and Sleep Patterns Among Mexican Adults: Results from ENSANUT-2012

To examine the independent association of household food insecurity with sleep duration and quality in a nationally representative survey of adults in Mexico. The Latin American and Caribbean Food Security Scale was used to categorize households as secure, mild (43.7 %), moderate (19.0 %), or severe (11.8 %). We assessed the association between household food insecurity and self-reported sleep duration and quality among 11,356 adults using weighted multinomial and binomial logistic regression. After adjusting for potential confounders, a significant association was found between severe household food insecurity and getting less than the recommended 7-8 h of sleep [adjusted odds ratio (AOR) =1.83, 95 % confidence interval (CI) =1.37-2.43]. Compared with food-secure households, odds of poor sleep quality increased with level of severity (AOR = 1.27, 95 % CI 1.04-1.56 for mild; AOR = 1.71, 95 % CI 1.36-2.14 for moderate; and AOR = 1.89, 95 % CI 1.45-2.45 for severe household food insecurity). Household food insecurity is associated with inadequate sleep duration and poor sleep quality among Mexican adults. This study underscores the adverse effects of household food insecurity on the well-being of vulnerable populations.
