BACKGROUND/AIMS A deficit of various hormones during the process of aging and/or a heightened inflammatory state may be causally linked to the development of frailty. Phytoestrogens as weak estrogens, antioxidants, and anti-inflammatory agents may counteract this process. METHODS In a cross-sectional study including two cycles of the National Health and Nutrition Examination Survey (NHANES, i...

It is claimed the hierarchical-age-period-cohort (HAPC) model solves the age-period-cohort (APC) identification problem. However, this is debateable; simulations show situations where the model produces incorrect results, countered by proponents of the model arguing those simulations are not relevant to real-life scenarios. This paper moves beyond questioning whether the HAPC model works, to wh...

Mental health is a key component of a child's overall wellbeing. Previous research using data from the National Health Interview Survey (NHIS) found that about 6% of adolescents have serious emotional or behavioral difficulties. Both medication and nonmedication services have been found to be effective for treatment. Two recent reports from the National Center for Health Statistics have present...

Previous research on cancer information focused on active seeking, neglecting information gathered through routine media use or conversation ("scanning"). It is hypothesized that both scanning and active seeking influence knowledge, prevention, and screening decisions. This study uses Health Information National Trends Survey (HINTS, 2003) data to describe cancer-related scanning and seeking be...

Using data from the 1997-2004 National Health Interview Survey (NHIS), we examine the role of chronic conditions in recent declines in late-life disability prevalence. Building upon prior studies, we decompose disability declines into changes in the prevalence of chronic conditions and in the risk of disability given a condition. In doing so, we extend Kitigawa's (1955) classical decomposition ...

Recent studies have demonstrated the importance of flavonoid intake and disease risk, however the association between flavonoid intake and obesity has not been evaluated in a nationally representative sample of US adults. The objective of the study was to evaluate the association between flavonoid consumption and established risk factors for obesity and obesity-related inflammation. Data from a...

IMPORTANCE Between 1980 and 2000, the prevalence of obesity increased significantly among adult men and women in the United States; further significant increases were observed through 2003-2004 for men but not women. Subsequent comparisons of data from 2003-2004 with data through 2011-2012 showed no significant increases for men or women. OBJECTIVE To examine obesity prevalence for 2013-2014 ...

This article reports data concerning silicosis-related web-activities using Google Trends (GT) capturing the Internet behavior in the USA for the period 2004-2010. GT-generated data were then compared with the most recent available epidemiological data of silicosis mortality obtained from the Centers for Disease Control and Prevention for the same study period. Statistically significant correla...
