The relationship between sleep duration and snack consumption pattern In adults in Isfahan, Najafabad and Arak: Isfahan Healthy Heart Program

Considering the association between sleep duration and lifestyle factors, this study was conducted to determine the relationship between sleep duration and the type of snack consumption.

This cross-sectional study was done on 9572 people aged over 19 years in Isfahan, Najafabad and Arak counties in the framework of the last phase of Isfahan Healthy Heart Program (IHHP). Dietary information was obtained through a food frequency questionnaire. According to the hours of sleep per day, participants were stratified into three groups with low (≤6 hours), adequate (≥6 and ≤9 hours) and long (≥9 hours) sleep duration. Multiple logistic regression was used to examine the relationship between snack type and sleep duration.

Participants consisted of 4028 males and 3882 females. People who slept more than 9 hours consumed more fruits and natural juices than people who had adequate sleep duration (OR = 1.01; 95% CI: 1.002-1.02). Also, people with longer sleep duration consumed fewer amounts of nuts than people with adequate sleep duration (OR = 0.97; 95% CI: 0.94-0.99). Consumption of soft drinks and industrial juices in people with short sleep was more than people with adequate sleep duration (OR = 1.04; 95% CI: 1.01-1.05).

According to the results, although there may be a relationship between sleep duration and choosing a healthy or unhealthy snacks, it is not possible to determine a conspicuous pattern for snacks.
