Arthritis and cognitive impairment in older adults
Adults aged 65 or older with arthritis may be at increased risk for cognitive impairment [cognitive impairment but not dementia (CIND) or dementia]. Studies have found associations between arthritis and cognition impairments; however, none have examined whether persons with arthritis develop cognitive impairments at higher rates than those without arthritis. Using data from the Health and Retirement Study, we estimated the prevalence of cognitive impairments in older adults with and without arthritis, and examined associations between arthritis status and cognitive impairments. We calculated incidence density ratios (IDRs) using generalized estimating equations to estimate associations between arthritis and cognitive impairments adjusting for age, sex, race/ethnicity, marital status, education, income, depression, obesity, smoking, the number of chronic conditions, physical activity, and birth cohort. The prevalence of CIND and dementia did not significantly differ between those with and without arthritis (CIND: 20.8%, 95% CI 19.7-21.9 vs. 18.3%, 95% CI 16.8-19.8; dementia: 5.2% 95% CI 4.6-5.8 vs. 5.1% 95% CI 4.3-5.9). After covariate control, older adults with arthritis did not differ significantly from those without arthritis for either cognitive outcome (CIND IDR: 1.6, 95% CI = 0.9-2.9; dementia IDR: 1.1, 95% CI = 0.4-3.3) and developed cognitive impairments at a similar rate to those without arthritis. Older adults with arthritis were not significantly more at risk to develop cognitive impairments and developed cognitive impairments at a similar rate as older adults without arthritis over 6 years

Osteoarthritis and Sleep: The Johnston County Osteoarthritis Project
Objective—Little is known about the association of symptomatic osteoarthritis (OA) with sleep
disturbance. We compared the prevalence and severity of current sleep problems among
individuals with and without symptomatic hip or knee OA in a large, community-based sample.
Methods—Participants (N = 2682, 28% with symptomatic hip or knee OA) were from the
Johnston County Osteoarthritis Project. Six sleep variables were grouped into 2 categories:
insomnia (trouble falling asleep, trouble staying asleep, or waking early) and insufficient sleep
(daytime sleepiness, not enough sleep, or not feeling rested). The presence of any sleep problem
(insomnia or insufficient sleep) was also assessed, as were annual frequency and cumulative days
of sleep problems. Adjusted models examined associations of symptomatic OA with sleep
problems controlling for demographic characteristics, obesity, self-reported health, and depressive
symptoms.
Results—Symptomatic hip or knee OA was associated with increased odds of any sleep problem
(odds ratio 1.25, 95% confidence interval 1.02–1.54), insomnia (OR 1.29, 95% CI 1.07–1.56), and
insufficient sleep (OR 1.35, 95% CI 1.12–1.62) in adjusted models. Among participants with sleep
problems, those with symptomatic OA reported higher median numbers of annual and cumulative days of insomnia and insufficient sleep, although these associations were not statistically
significant in adjusted models.
Conclusion—Symptomatic hip and knee OA are significantly associated with sleep problems,
independent of other factors related to sleep difficulties, including self-rated health and
depression. Patients with OA should be regularly screened for sleep disturbance as part of routine
care
Depression, stigma and social isolation: The psychosocial trifecta of primary chronic cutaneous lupus erythematosus, a cross-sectional and path analysis
OBJECTIVE: Depression is common in individuals with chronic cutaneous lupus erythematosus (CCLE). However, how CCLE may impact patients\u27 psychological well-being is poorly understood, particularly among disproportionally affected populations. We examined the relationships between depression and psychosocial factors in a cohort of predominantly Black patients with primary CCLE (CCLE without systemic manifestations).
METHODS: Cross-sectional assessment of individuals with dermatologist-validated diagnosis of primary CCLE. NIH-PROMIS short-forms were used to measure depression, disease-related stigma, social isolation and emotional support. Linear regression analyses (ɑ=0.05) were used to test an a priori conceptual model of the relationship between stigma and depression and the effect of social isolation and emotional support on that association.
RESULTS: Among 121 participants (87.6% women; 85.1% Black), 37 (30.6%) reported moderate to severe depression. Distributions of examined variables divided equally among those which did (eg, work status, stigma (more), social isolation (more), emotional support (less)) and did not (eg, age, sex, race, marital status) significantly differ by depression. Stigma was significantly associated with depression (b=0.77; 95% CI0.65 to 0.90), whereas social isolation was associated with both stigma (b=0.85; 95% CI 0.72 to 0.97) and depression (b=0.70; 95% CI0.58 to 0.92). After controlling for confounders, stigma remained associated with depression (b=0.44; 95% CI0.23 to 0.66) but lost significance (b=0.12; 95% CI -0.14 to 0.39) when social isolation (b=0.40; 95% CI 0.19 to 0.62) was added to the model. Social isolation explained 72% of the total effect of stigma on depression. Emotional support was inversely associated with depression in the univariate analysis; however, no buffer effect was found when it was added to the multivariate model.
CONCLUSION: Our findings emphasise the psychosocial challenges faced by individuals living with primary CCLE. The path analysis suggests that stigmatisation and social isolation might lead to depressive symptoms. Early clinical identification of social isolation and public education demystifying CCLE could help reduce depression in patients with CCLE
Limited educational attainment and radiographic and symptomatic knee osteoarthritis: a cross-sectional analysis using data from the Johnston County (North Carolina) Osteoarthritis Project
Abstract Introduction Applying a cross-sectional analysis to a sample of 2,627 African-American and Caucasian adults aged ≥ 45 years from the Johnston County Osteoarthritis Project, we studied the association between educational attainment and prevalence of radiographic knee osteoarthritis and symptomatic knee osteoarthritis. Methods Age- and race-adjusted associations between education and osteoarthritis outcomes were assessed by gender-stratified logistic regression models, with additional models adjusting for body mass index, knee injury, smoking, alcohol use, and occupational factors. Results In an analysis of all participants, low educational attainment (<12 years) was associated with higher prevalence of four knee osteoarthritis outcomes (unilateral and bilateral radiographic and symptomatic osteoarthritis). Women with low educational attainment had 50% higher odds of having radiographic knee osteoarthritis and 65% higher odds of symptomatic knee osteoarthritis compared with those with higher educational attainment (≥ 12 years), by using fully adjusted models. In the subset of postmenopausal women, these associations tended to be weaker but little affected by adjustment for hormone replacement therapy. Men with low educational attainment had 85% higher odds of having symptomatic knee osteoarthritis by using fully adjusted models, but the association with radiographic knee osteoarthritis was explained by age. Conclusions After adjustment for known risk factors, educational attainment, as an indicator of socioeconomic status, is associated with symptomatic knee osteoarthritis in both men and women and with radiographic knee osteoarthritis in women
