ABSTRACT

Introduction: The assessment of the deleterious effects of insomnia on daytime functioning is an essential part of the epidemiology of insomnia.
Objectve: To describe the demographic characteristics, symptoms of insomnia and daytime consequences in Mexican patients enrolled in the international study EQUINOX.
Methods: The EQUINOX descriptive study originally included outpatients pertaining to 10 countries. In this report we analyzed data of patients attending primary care facilities in Mexico, with different reasons for medical consultation. We interviewed all patients for two consecutive days of each workweek. Those identified with insomnia received a standardized questionnaire that included anthropometric and socio-demographic characteristics of insomnia, daytime consequences of insomnia and type of intervention to treat it.
Results: We evaluated 3,021 Mexicans, with a frequency of 62.3% insomnia. Difficulty initiating sleep was present in 1,135 patients (82.4%), difficulty maintaining sleep in 1,108 (80.4%), early morning awakenings in 983 (71.3%) and restless sleep in 1,144 patients (83%). The social, emotional, and professional functioning was affected in 75% of patients and in 25% this involvement was severe.
Conclusions: Insomnia is a very common sleep disorder in Mexicans. Primary care physicians play a key role in the identification, treatment and monitoring of insomnia and its daytime consequences.
