Association of Sleep Quality with Dietary Diversity and BMI

Abstract

Adequate quality sleep is important for ideal health condition. The recommended hours of sleep are 7-9 hours for children, adolescents, adults and elderly to maintain good health. Recent developments in the field of technology have changed the habits and lifestyles of students which causes sleep disorders among students. Sleep quality of the people is affected by several factors such as gender, age, occupation, psychological state but recently it has been recognized that dietary diversity and BMI are also implicated in sleep quality of people. Dietary diversity is the variety or the number of different food group’s people eats over the time given. Studies done in the past have indicated that sleep duration is associated positively with fruits and vegetables intake while the consumption of sweet and snack food items including junk food would lead to lesser sleep duration. Also, short sleep duration and poor sleep were associated with an increase in BMI and fat mass. Another study indicate that poor sleep quality predict obesity and high body fat mass among adults. Several studies have argued that excessive introduction of food, which leads to an increased risk of obesity in people with short term sleep, is associated with changes in hormones responsible for hunger and appetite control especially leptin and ghrelin. Adults and children that sleep less, have an increase in obesity and overweight risk with dysfunctional eating behaviors, decreased physical activity and metabolic changes. The review aims to see how the sleep quality is associated with BMI and dietary diversity in different age group people.
