Omics feature selection with the extended SIS R package: identification of a body mass index epigenetic multi-marker in the Strong Heart Study
Am J Epidemiol. 2024 Feb 20:kwae006. doi: 10.1093/aje/kwae006. Online ahead of print.ABSTRACTThe statistical analysis of omics data poses a great computational challenge given its ultra-high dimensional nature and frequent between-features correlation. In this work, we extended the Iterative Sure Independence Screening (ISIS) algorithm by pairing ISIS with elastic-net (Enet) and two versions of adaptive Enet (AEnet and MSAEnet) to efficiently improve feature selection and effect estimation in omics research. We subsequently used genome-wide human blood DNA methylation data from American Indians of the Strong Heart Study (N...

Month-to-month all-cause mortality forecasting: A method allowing for changes in seasonal patterns
In this study, we propose a flexible method to forecast all-cause mortality in real-time considering short-term changes in seasonal patterns within an epidemiological year. All-cause mortality data has the advantage of being available with less delay than cause-specific mortality data. We use all-cause monthly death counts from national statistical offices for Denmark, France, Spain, and Sweden from seasons 2012/13 through 2021/22 to demonstrate the performance of the proposed approach. The method forecasts the deaths one-month-ahead, based on their expected ratio to the next month. Prediction intervals are obtained via bo...

Exercise to socialize? Bidirectional relationships between physical activity and loneliness in middle-aged and older American adults
Am J Epidemiol. 2024 Feb 6:kwae001. doi: 10.1093/aje/kwae001. Online ahead of print.ABSTRACTPhysical inactivity and loneliness are both associated with health risks and can affect each other through various social and behavioral mechanisms. However, current evidence on this relationship is equivocal and mostly based on cross-sectional data. This longitudinal study aims to determine whether current levels of physical activity (moderate- and vigorous-intensity) and loneliness are associated with future respective states of themselves and each other. Data from waves 6-14 (2002-2018) of the Health and Retirement Study were use...

Harnessing Causal Forests for Epidemiologic Research: Key Consideration
Am J Epidemiol. 2024 Feb 6:kwae003. doi: 10.1093/aje/kwae003. Online ahead of print.ABSTRACTAssessing heterogeneous treatment effects (HTEs) is an essential task in epidemiology. The recent integration of machine learning into causal inference has provided a new, flexible tool for evaluating complex HTEs: causal forest. Jawadekar et al. (Am J Epidemiol. 2023) introduce this innovative approach and offer practical guidelines for applied users. Building on their work, this commentary provides additional insights and guidance to promote the understanding and application of causal forest in epidemiologic research. We start wit...
