Relationship between the presence of insomnia and walking physical activity and diet quality: A cross-sectional study in a sample of Spanish adults
Abstract
INTRODUCTION AND OBJECTIVES
Certain lifestyle habits may influence aspects of sleep quality, such as insomnia. The main objective of the present study was to analyze the relationship of the presence of insomnia, with walking physical activity and diet quality in an adult population.
PATIENTS AND METHODS
A cross-sectional descriptive study was performed (subanalysis of the TRIPLE A study) between January of 2014 to June of 2015. A total of 454 subjects were selected by consecutive sampling. Insomnia was evaluated with the Atenas scale, diet quality using the diet quality index (DQI) questionnaire, and physical activity using pedometers for seven days, evaluating the total number of steps, aerobic steps, and energy expended.
RESULTS
Of all patients, 26.8% presented with insomnia (33.8% in women and 17.5% in men). In a adjusted model, the mean differences of total steps/day, aerobic steps/day, and kilocalories/day spent in performing physical activity, between no insomnia group and insomnia group were: 1022.5 (95% CI: 177.9-1867.0), 743.9 (95% CI: 68.3-1419.4) and 39.8 (95% CI: 5.7-73.9), respectively. We did not find an association between the diet quality index (DQI) and insomnia.
CONCLUSIONS
The findings suggest that completing daily a greater total number of steps, aerobic steps, and energy expended by walking, could be correlated with less insomnia, independent of age, sex, and other confounding variables. However, no relationship was observed between diet quality and…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 454 participants or records.
