Mala-movida: Late bed-timing and wake-up induce malnutrition and underweight in youngsters

malnutrition. Alcohol intake, coffee, cigarette smoking, illicit and stimulating drugs habits, work and school achievements are also considered. Average sleep duration (hours) is 7.26 ± 1.17 (2–11 hours), bed timing 2.00 a.m. ± 1.18 0 (0–6 hours), bed waking up 9.15 0 ± 1.29 0 am (5–16 hours), with an average daily time spent within movida of 3.15 0 ± 2.29 0 (0–14 hours). There is a reverse correlation of BMI with the nightlife time, p40.001, with the waking-up hour, p50.001, and with the sleep duration in hours, p40.0001. These effects were remarkably greater in the 49 youngsters (5.60%) who were frankly underweight (BMI518.0); since these effects resemble those of night shift workers, the term mala movida (bad nightlife) is becoming of current use.
