0836 BORN IN THE USA OR BORN IN MEXICO? IMPLICATIONS FOR SLEEP DURATION, SLEEP QUALITY, SLEEP DISORDERS SYMPTOMS AT THE US-MEXICO BORDER

Abstract Introduction: Previous studies have shown that at the population level, being born in Mexico is associated with fewer sleep disturbances. However, previous studies generally did not use standardized/validated instruments and were not able to account for acculturation. The present study examined these relationships in a small city at the US-Mexico border. Methods: Data were collected from N=100 adults (age 18–60, 53% female) of Mexican descent from the city of Nogales, AZ, on the US-Mexico border. Questionnaires were in English or Spanish. Participants were asked if they were born in the USA or Mexico. Sleep was assessed with the Pittsburgh Sleep Quality Index (PSQI; sleep quality score and sleep duration single-item), and Insomnia Severity Index (items for difficulty falling asleep, difficulty staying asleep, early morning awakenings, categorized as none, mild, moderate, and severe). Regression analyses (linear for continuous variables and multinomial for symptoms) adjusted for age, sex, and education level. Post-hoc analyses examined acculturation (measured with the Acculturation Rating Scale for Mexican-Americans, Mexican and Anglo Orientation Scales) as a mediator. Results: 66% of the sample was born in Mexico. Being born in the USA was associated with 56 fewer minutes of nighttime sleep (p
