Social Jetlag Is Associated with the Frequency of Consumption of Sugar-Sweetened Beverages and a High BMI Percentile in Adolescents: Results of the Cross-Sectional Family Life, Activity, Sun, Health, and Eating (FLASHE) Study.

Background: Social jetlag (SJL) occurs in adolescents due to misalignment of the biological and social clocks, so that most teens wake up earlier than their biological clocks on weekdays and delay bedtime and wake up time on weekends. This shift in sleep timing among adolescents is associated with an adverse endocrine and behavioral risk profile, in addition to increased food consumption and increased body mass index (BMI).

Objective: The aim of this study was to determine the association between SJL, and the frequency of consumption of multiple food and beverage groups and BMI percentile in adolescents.

A systematic review of nutrition-based practices in prevention of hypertension among healthy youth.

The aim of this systematic review was to analyze the results of observational and interventional research/studies on nutrition-based practices in the prevention of hypertension among healthy youth. The MEDLINE/PubMed database was searched using the key words, "hypertension," "nutrition/diet," "prevention" and "youth." Inclusion criteria were: 1) sample with a majority of adolescents, defined as 10-24 years of age, or findings for adolescents reported separately from other age groups; 2) primary research reports; 3) studies with normotensive participants; and 4) studies that focused on preventing hypertension/lowering blood pressure through at least one nutritional practice.
