Net Effects Of Correlated Determinants Of Health Among U.S. Older Adults, Haomiao Jia, E I. Lubetkin

Publications and Research

Background

The health effect produced by a contributing factor alone may be different from the effect when other interacting factors are present. The effects of a set of contributors, estimated by regression coefficients, may be invalid or inappropriate if some of the predictors are correlated or the model has interaction and nonlinear terms. The net effect (NE) of a given contributing factor is the effect produced by the factor alone, not by other factors due to their correlations with the factor of interest. This study estimated NE of selected determinants of health for U.S. older adults.

Use Of A Microsimulation Method For Assessing Dynamics Of Smoking Status And Gains In Life Expectancy After Quitting In A Longitudinal Cohort Of Us Older Adults, Haomiao Jia, Erica I. Lubetkin

Publications and Research

Objectives: Previous studies were unable to estimate the dynamics of smoking status in the US elderly general population, and no study has assessed the benefit of quitting in terms of resultant gains in life expectancy. We proposed a novel method to estimate the per cent of quitting in remaining lifetime, successful quitting and relapse, as well as life expectancy by participants' baseline smoking status.

Design: Longitudinal cohort.

Setting: US community-dwelling population.

Participants: Respondents from the Medicare Health Outcome Survey Cohort 15 (baseline 2012, follow-up 2014). We included respondents who were aged ≥65 years and alive at the baseline and participated …

Association Between Self-Reported Body Mass Index And Active Life Expectancy In A Large Community-Dwelling Sample Of Older U.S. Adults, Haomiao Jia, Erica I. Lubetkin

Publications and Research

Background: Obesity may have a protective effect (greater survival) in older adults, a finding known as the "obesity paradox." This study examined the association between self-reported body mass index (BMI) and active life expectancy (ALE) among older U.S. adults.

Methods: Using the Medicare Health Outcomes Survey Cohort 15 (2012 baseline, 2014 follow-up), we estimated life expectancy and ALE by participants' baseline BMI and age using multi-state models. A participant was classified as in an active state if this person reported having no difficulty for any of these six activities of daily living (ADLs).

Results: Small differences in life expectancy were …

Validity, Reliability, And Measurement Error Of A Sit-To-Stand Power Test In Older Adults: A Pre-Registered Study, Anoop T. Balachandran

Publications and Research

Objectives: Lower body power declines with age and is associated with decreased physical function in older adults. However, the majority of the tools available to measure power are expensive and require considerable space and expertise to operate. The purpose of this study was to assess the validity, reliability, and measurement error of a sit-to-stand power test (STSp) to assess lower body power. Methods: 51 community-dwelling adults, 65 years or older, completed a power test using a pneumatic leg press (LP), the Short Physical Performance Battery (SPPB) that includes a test of balance, usual walking speed, and chair stand tests; Timed …

An Approach To Classifying Subjective Cognitive Decline In Community-Dwelling Elders, Laura A. Rabin, Cuilling Wang, Jacqueline A. Mogle, Richard B. Lipton, Carol A. Derby, Mindy J. Katz

Publications and Research

Introduction: Subjective cognitive decline (SCD) may be an early symptomatic man- ifestation of Alzheimer’s disease, though published research largely neglects how to classify SCD in community-based studies.

Methods: In neuropsychologically intact Einstein Aging Study participants (n = 1115; meanage=78;63%female;30%non-White),weusedCoxmodelstoexaminetheasso- ciation between self-perceived cognitive functioning at baseline (using three different approaches) and incident amnestic mild cognitive impairment (aMCI) with covariates of age, sex, education, race/ethnicity, general (objective) cognition, depressive symp- toms, and four other SCD-related features.

Results: After a median of 3 years, 198 participants developed aMCI. In models that included all the variables, self-perceived cognitive functioning was consistently asso- ciated …

Life Expectancy And Active Life Expectancy By Disability Status In Older U.S. Adults, Haomiao Jia, Erica I. Lubetkin

Publications and Research

Objectives

The Medicare Health Outcome Survey (HOS) is the largest longitudinal survey of the U.S. community-dwelling elderly population. This study estimated total life expectancy, active life expectancy (ALE), and disability-free life expectancy (DFLE) by disability status among HOS participants.

Methods

Data were from the Medicare HOS Cohort 15 (baseline 2012, follow-up 2014). We included respondents aged ≥ 65 years (n = 164,597). Participants’ disability status was assessed based on the following six activities of daily living (ADL): bathing, dressing, eating, getting in or out of chairs, walking, and using the toilet. The multi-state models were used to estimate life expectancy, …

Aims and objectives: To gain insight into the request, use and associated factors of involuntary treatment in people with dementia (PwD) receiving professional home care in the Netherlands and Belgium.

Background: Most of the PwD remain living at home as long as possible. Due to complex care needs, this can result in an increased risk for care provided against the wishes of the client and/or to which the client resists, referred to as involuntary treatment.

Design: Secondary data analyses of two cross-sectional surveys.

Methods: Dementia case managers and district nurses filled in a questionnaire for each PwD in their …

Life Expectancy And Active Life Expectancy By Marital Status Among Older U.S. Adults Results From The U.S. Medicare Health Outcome Survey (Hos), Haomiao Jia, Erica I. Lubetkin

Publications and Research

Background: Previous investigations of the relationship between marital status and life expectancy and healthy life expectancy rely on the assumption that participants will remain in a given marital status until death. This study estimated total life expectancy (TLE) and active life expectancy (ALE) for respondents by their baseline marital status using a large longitudinal sample of the U.S. community-dwelling elderly population.

Methods: Data were from the Medicare Health Outcomes Survey Cohort 15 (2012 baseline, 2014 follow-up). We included respondents aged ≥65 years (n = 164,597). Multi-state models estimated TLE and ALE by marital status to allow participants' marital status to …

Associations Of Hemoglobin A1c With Cognition Reduced For Long Diabetes Duration, Jeremy M. Silverman, James Schmeidler, Pearl G. Lee, Neil B. Alexander, Michal Schnaider Beeri, Elizabeth Guerrero-Berroa, Rebecca K. West, Mary Sano, Martina Nabozny, Carolina Rodriguez Alvarez

Publications and Research

Introduction: Associations of some risk factors with poor cognition, identified prior to age 75, are reduced or reversed in very old age. The Protected Survivor Model predicts this interaction due to enhanced survival of those with extended risk factor duration. In a younger sample, this study examines the association of cognition with the mean hemoglobin A1c risk factor over the time at risk, according to its duration.

Methods: The interaction of mean hemoglobin A1c (average = 9.8%), evaluated over duration (average = 116.8 months), was examined for overall cognition and three cognitive domains in a sample of 150 “young-old” veterans …

Physical, Cognitive, Social And Mental Health In Near-Centenarians And Centenarians Living In New York City: Findings From The Fordham Centenarian Study, Daniela S. Jopp, Min-Kyung S. Park, Jonathan Lehrfeld, Michelle E. Paggi

Publications and Research

Background: Despite their strong increase, the population of the very old, including near-centenarians and centenarians, represent an unstudied and underserved population. Available studies mostly concentrate on predictors of exceptional longevity, but rarely extend their focus to other areas of functioning. Also, little is known about what contributes to experiencing a quality life in very old age. The present population-based study aims at providing a comprehensive picture of key domain of functioning, including physical, cognitive, social and mental function in very old individuals and to determine predictors of mental health indicators.

Methods: A total of 119 individuals aged 95 to 107 …
