Background: To date, few studies have compared the dietary quality of US adults with diabetes mellitus (DM), osteoarthritis (OA), and rheumatoid arthritis (RA) by age groups. Methods: This study used cross-sectional data from adult participants from National Health and Nutrition Examination Survey 2011–2016 to identify dietary quality measured by Healthy Eating Index (HEI)-2015 total and component scores and self-reported disease status for DM, OA, and RA. Associations between the disease status and HEI-2015 total/component scores among younger adults aged 20–59 years (n = 7988) and older adults aged 60 years and older (n = 3780) were examined using logistic regression models. These accounted for the complex survey design and were adjusted for self-reported disease status, sex, race/ethnicity, education levels, income status, weight status, physical activity levels, and smoking status. Results: Among younger adults, 7% had DM, 7% had OA, and 3% had RA. Among older adults, 20% had DM, 32% had OA, and 6% had RA. Moderate added sugar intake was associated with diabetes in all adults. Excess sodium intake was associated with DM among younger adults. Inadequate seafood and plant protein intake was associated with RA among younger adults, while a poor overall dietary pattern was associated with RA among older adults. Conclusions: The dietary quality of US adults varied by self-reported DM, OA, and RA status, and each varied by age group.

Background: COVID-19 vaccines are now available under Emergency Use Authorization for children ages 6 months to 5 years. We examined parents’ intentions to vaccinate their children under the age of 5 years and assessed whether their confidence in making an informed decision about vaccination (decision self-efficacy) was associated with these intentions. Method: We conducted a cross-sectional online survey of U.S. parents between 23 March and 5 April 2022. We examined associations between parental intention to vaccinate their young children (<age 5 years) and confidence in vaccine decision making (decision self-efficacy). A multivariable multinomial logistic regression model was used to obtain adjusted odds ratios (AORs) and 95% confidence intervals (CIs) of parental intention (categorized as intend to vaccinate, unsure, or do not intend to vaccinate). Results: Of the 591 parents in this sample, 49% indicated that they intended to vaccinate their child(ren), 29% reported that they would not, and 21% were undecided. In bivariate analyses, race/ethnicity, health insurance, flu vaccination in the past 12 months, and parental COVID-19 vaccination status were significantly related to parental intention to vaccinate their child(ren). In the multivariable analyses, which controlled for these factors, parents who intended to vaccinate their child(ren) had greater confidence in their ability to make informed decisions about COVID-19 vaccinations compared to those who were unsure about vaccination. Each one standard deviation in the Decision Self-Efficacy score was associated with a 39% increase in intention to vaccinate one’s child versus being unsure about vaccination (AOR 1.39, 95% CI 1.09, 1.77). Conclusions: Parents who are unsure about vaccinating their children against COVID-19 may benefit from interventions designed to increase their ability to obtain, understand, and utilize information to make informed decisions.

In the United States, vaccination rates for many routinely recommended vaccines have recovered to pre-pandemic levels, yet human papillomavirus (HPV) vaccination rates still lag pre-pandemic levels. This study sought to uncover the potential effects of the pandemic on attitudes about the HPV vaccine, and factors associated with changes in attitudes. We conducted a national survey (n = 3968) of U.S. mothers with children aged 9–17 years. Outcome variables measured changes in attitude toward the HPV vaccine following the pandemic. Two logistic regression models identified predictors of (1) those who did not have attitude changes (always negative vs. always positive), and (2) those who reported attitude changes (change to negative vs. change to positive). Attitudes toward the HPV vaccine remained unchanged in 78.9% of participants (58.1% positive, 20.8% negative). Of the 21.1% reporting changed attitudes, 9.6% changed to positive and 11.5% to negative. Those reporting changing to a negative attitude had a greater odds of reporting conservative political views, and being unsure/undecided about vaccinating their child against HPV compared to those who reported changing to a positive attitude. Targeted strategies are needed to address erosion in confidence in the HPV vaccine and other vaccines resulting from mis- and disinformation associated with the COVID-19 pandemic and future pandemics.

Background: To date, little is known about cardiovascular disease risks among older adults with non-valvular atrial fibrillation by their association with diabetes and osteoarthritis status, based on longitudinal data with substantial amounts of non-white individuals. The objective of this study was to examine the risks for three cardiovascular diseases: stroke, acute myocardial infarction (AMI), and heart failure (HF), by diabetes and osteoarthritis status among older adults with non-valvular atrial fibrillation in Hawaii. Methods: We conducted a retrospective observational cohort study for older adults (65 years and older) with non-valvular atrial fibrillation using the Hawaii Medicare data 2009–2017. Their risks for the three cardiovascular diseases by diabetes and osteoarthritis status (diabetes, osteoarthritis, diabetes and osteoarthritis, and without diabetes and osteoarthritis) were examined by multivariable Cox proportional hazard regression models. Results: The analysis included 19,588 beneficiaries followed up for a maximum of 3288 days (diabetes: n = 4659, osteoarthritis: n = 1978, diabetes and osteoarthritis: n = 1230, without diabetes and osteoarthritis: n = 11,721). Among them, those diagnosed with the cardiovascular diseases were identified (stroke: diabetes n = 837, osteoarthritis n = 315, diabetes and osteoarthritis n = 184, without diabetes and osteoarthritis n = 1630)(AMI: diabetes n = 438, osteoarthritis n = 128, diabetes and osteoarthritis n = 118, without diabetes and osteoarthritis n = 603)(HF: diabetes n = 2254, osteoarthritis n = 764, diabetes and osteoarthritis n = 581, without diabetes and osteoarthritis n = 4272). After adjusting for age, sex, race/ethnicity, and other potential confounders, those with diabetes and osteoarthritis had higher risks for HF (hazard ratio: 1.21 95% confidence interval: 1.10–1.33) than those without diabetes and osteoarthritis. They also had higher risks than those with osteoarthritis for HF. Those with diabetes had higher risks for all three cardiovascular diseases than the other three groups. Conclusions: Variation in cardiovascular disease risks for older adults with non-valvular atrial fibrillation in Hawaii exists with diabetes and osteoarthritis status.
