Abstract
Introduction: Nutrition, physical activity, and sleep deficits contribute to diminished health status in healthcare workers (HCWs). The purpose of this study was to focus attention on HCWs by incorporating precision health approaches to address lifestyle behaviors believed to influence immune health, cardiometabolic status, and wellbeing.
Methods: In this 1-year prospective observational study, a digital dashboard was created to post a health promotion video, targeted health messages, and personal health data accessible to each participant. Activity-sleep trackers were provided to capture actual step and sleep activity. Lifestyle questionnaires, serum biomarkers, body composition by bioelectrical impedance analysis, and blood pressure were obtained at four timepoints; gene expression was measured at three timepoints. Genes linking host immune response to key nutrients were isolated for correlational analyses with lifestyle behaviors. Participants received a comprehensive summary of their personal results at 12 months. Primary outcome was participant engagement.
Results: 104 HCWs enrolled between July and October 2021. At 12 months, 60% of participants were high adopters for device-wear time and daily step threshold. Daily steps declined by 831 (±3,441) steps per day, t statistic -1.742, p = 0.09 after 1 year. Insomnia Severity Index results suggested persistent subclinical insomnia with a mean score of 8.1 (±6.1) at 12 months. Thirteen genes had a moderate correlation with steps, r (49) = 0.29-37, sleep, r (56) = 0.27-0.37, distance, r (61) = 0.28, and Insomnia Severity Index, r (56) = 0.30-0.38, p = NS, after Benjamini-Hochberg adjustment.
Conclusion: Participant engagement may have contributed to favorable behavior change in the first 6 months, but this was not sustained at 12 months. Novel strategies are needed to boost engagement for longer studies, promote HCW wellness to optimize immune and cardiometabolic health, and abate chronic disease progression.
期刊介绍：
Much of contemporary investigation in the life sciences is devoted to the molecular-scale understanding of the relationships between genes and the environment — in particular, dynamic alterations in the levels, modifications, and interactions of cellular effectors, including proteins. Frontiers in Molecular Biosciences offers an international publication platform for basic as well as applied research; we encourage contributions spanning both established and emerging areas of biology. To this end, the journal draws from empirical disciplines such as structural biology, enzymology, biochemistry, and biophysics, capitalizing as well on the technological advancements that have enabled metabolomics and proteomics measurements in massively parallel throughput, and the development of robust and innovative computational biology strategies. We also recognize influences from medicine and technology, welcoming studies in molecular genetics, molecular diagnostics and therapeutics, and nanotechnology.
Our ultimate objective is the comprehensive illustration of the molecular mechanisms regulating proteins, nucleic acids, carbohydrates, lipids, and small metabolites in organisms across all branches of life.
In addition to interesting new findings, techniques, and applications, Frontiers in Molecular Biosciences will consider new testable hypotheses to inspire different perspectives and stimulate scientific dialogue. The integration of in silico, in vitro, and in vivo approaches will benefit endeavors across all domains of the life sciences.
