ABSTRACT To estimate the national prevalence of arthritis-attributable work limitation (AAWL) among persons ages 18-64 with doctor-diagnosed arthritis and examine correlates of AAWL.
Using the 2002 National Health Interview Survey, we estimated the prevalence of AAWL (limited in whether individuals work, the type of work they do, or the amount of work they do) and correlates of AAWL in univariable and multivariable-adjusted logistic regression analyses. Survey data were analyzed in SAS and SUDAAN to account for the complex sample design.
A total of 5.3% of all US adults ages 18-64 reported AAWL; in this age group, AAWL is reported by approximately 30% of those who report arthritis. The prevalence of AAWL was highest among people ages 45-64 years (10.2%), women (6.3%), non-Hispanic blacks (7.7%), people with less than a high school education (8.6%), and those with an annual household income <$20,000 (12.6%). AAWL was substantially increased among people with arthritis-attributable activity limitations (multivariable-adjusted odds ratio [OR] 9.1, 95% confidence interval [95% CI] 7.1-11.6). The multivariable-adjusted likelihood of AAWL was moderately higher among non-Hispanic blacks (OR 1.6, 95% CI 1.2-2.3), Hispanics (OR 1.8, 95% CI 1.2-2.6), and people with high levels of functional/social/leisure limitations (OR 1.8, 95% CI 1.4-2.3) and was decreased among those with a college education (OR 0.6, 95% CI 0.4-0.8).
AAWL is highly prevalent, affecting millions of Americans and one-third of adults with doctor-diagnosed arthritis. Findings suggest the need for more targeted research to better understand the natural history, success of interventions, and effects of policy on AAWL. Public health interventions, including self-management education programs, may be effective in countering AAWL.

    ABSTRACT: A reliable method to evaluate and follow the course of arthritis is given by examination of the carpal bones within the wrist joint. Humans typically have eight such small angular bones arranged in two rows. The small size as well as the number make manual segmentation for an analysis of the disease progression a tedious process. Further, fully automatic approaches are still not very reliable. To support medical treatment we present a fully automatic machine learning approach which (i) finds a bounding box around every bone and (ii) outlines the contour and computes a 3-D model of every carpal. The proposed approach has been successfully evaluated on 110 clinical wrist data sets of arthritis patients. The data consists of 59 T1 and 51 T2 weighted MRI images. With the point-to-mesh error deviating from ground truth an average of 0.48 ± 0.45 mm / 0.59 ± 0.49 mm on T1 / T2 modality, accurate segmentation results have been achieved.

    ABSTRACT: More than 133 million Americans are living with chronic conditions and this number continues to rise (Partnership for Solutions, 2004); by 2020, it is estimated that 157 million people will suffer from chronic illnesses (Anderson, 2003), a large percentage of whom are in their child-rearing stage of life. Incorporating concepts from family systems and family development theories, this exploratory study examined the impact of maternal chronic physical illness on children. Specifically, it examined the extent to which length of illness and symptom severity of fibromyalgia and rheumatoid arthritis; mother’s age, educational level, and marital status; perceived effects of the illness on parent, child, and parent-child interactions; and parent and child’s perceived availability of and satisfaction with support are related to the child’s parentification. Two-hundred mothers and their oldest child, aged 11-17 years, answered the researcher-developed questionnaire that had been mailed to them; youths also completed the Parentification Questionnaire – Youth. Results indicated that parentification was greater for older children, females more than males, and boys whose mothers had the illness longer. Higher parentification scores also were obtained by children whose mothers reported lower satisfaction with support and who felt more burdened by their illness. Lower parentification scores were obtained by children who reported greater satisfaction with their support, said that they felt closer to their mothers, and whose mothers reported that they felt closer to their children. Implications of these findings for preventative strategies and intervention are discussed and suggestions for future research presented. To date, little attention has been paid to the impact of mothers’ chronic illness on their children. This study suggests that to reduce parentification in children whose mothers are chronically ill, increased support needs to be offered at all levels of the family system - the mother, the child, the mother-child dyad, and the family as a whole.
