Purpose:The aim of this study was to evaluate the efficacy of a 17-week,3-component lifestyle intervention for enhancing health behaviors during the coronavirus disease 2019(COVID-19)pandemic.Methods:A parallel-group(intervention and control)study was conducted amongst 79 airline pilots over a 17-week period during the COVID-19 pandemic.The intervention group(n=38)received a personalized sleep,dietary,and physical activity(PA)program.The control group(n=41)received no intervention.Outcome measures for sleep,fruit and vegetable intake,PA,and subjective health were measured though an online survey before and after the 17-week period.The changes in outcome measures were used to determine the efficacy of the intervention.Results:Significant main effects for time￡group were found for International Physical Activity Questionnaire-walk(p=0.02)and for all other outcome measures(p<0.01).The intervention group significantly improved in sleep duration(p<0.01;d=1.35),Pittsburgh Sleep Quality Index score(p<0.01;d=1.14),moderate-to-vigorous PA(p<0.01;d=1.44),fruit and vegetable intake(p<0.01;d=2.09),Short Form 12v2 physical score(p<0.01;d=1.52),and Short Form 12v2 mental score(p<0.01;d=2.09).The control group showed significant negative change for sleep duration,Pittsburgh Sleep Quality Index score,and Short Form 12v2 mental score(p<0.01).Conclusion:Results provide preliminary evidence that a 3-component healthy sleep,eating,and PA intervention elicit improvements in health behaviors and perceived subjective health in pilots and may improve quality of life during an unprecedented global pandemic.
