Background: Patients treated for hypothyroidism with levothyroxine (LT4) monotherapy may present with persistent hypothyroidism symptoms, including cognitive symptoms, despite having a normal thyroid stimulating hormone (TSH) level. It remains unclear whether LT4 monotherapy is sufficient to normalize cognitive function outcomes over time. Methods: This is a multisite longitudinal study of a diverse group of women during midlife representing 5 ethnic/racial groups from 7 enrollment sites across the United States in the Study of Women's Health Across the Nation. Women were screened for a history of thyroid disease and the use of LT4. The study consisted of two primary groups: women with LT4-treated hypothyroidism and control women without thyroid disease. Each participant completed up to 9 cognitive assessments over the study period testing processing speed, working memory, and episodic memory (immediate and delayed recall). Multivariable generalized linear mixed models of scores for each cognitive assessment were developed to determine the association between LT4-treated hypothyroidism and cognitive function trajectories. Covariates included sociodemographic, clinical characteristics, and menopausal status (pre/early peri, late peri, and surgical/post). Sensitivity analyses were conducted to assess the impact of abnormal TSH levels and practice effects (i.e., improvements in scoring after repeated testing). Results: Of the 2033 women who were included in the study, 227 (11.2%) met criteria for LT4-treated hypothyroidism. At baseline, both processing speed and working memory scores were higher in LT4-treated women (mean processing speed scores: 56.5 vs 54.4; p value = 0.006; mean working memory scores: 6.8 vs 6.4; p value = 0.018). However, when considering the effect of LT4-treated hypothyroidism over time, there were no significant differences in the rate of cognitive decline (in any measure) between the hypothyroidism and control groups with or without covariate adjustment. The results were similar when considering LT4-treated women with abnormal TSH levels or after minimizing practice effects. Conclusions: We observed no difference in cognitive decline between women with LT4-treated hypothyroidism and women without thyroid disease. For similar aged patients with cognitive complaints, if thyroid function testing is normal, clinicians should consider causes other than inadequate thyroid hormone treatment to explain these symptoms.

Background: Cognitive decline may progress for decades before dementia onset. Better cardiovascular health (CVH) has been related to less cognitive decline, but it is unclear whether this begins early, for all racial subgroups, and all domains of cognitive function. The purpose of this study was to determine the impact of CVH on decline in the 2 domains of cognition that decline first in White and Black women at midlife., Methods and Results: Subjects were 363 Black and 402 White women, similar in baseline age (mean±SD, 46.6±3.0 years) and education (15.7±2.0 years), from the Chicago site of the Study of Women's Health Across the Nation. Cognition, measured as processing speed and working memory, was assessed annually or biennially over a maximum of 20 years (mean±SD, 9.8±6.7 years). CVH was measured as Life's Essential 8 (blood pressure, body mass index, glucose, non-high-density lipoprotein cholesterol, smoking, physical activity, diet, sleep). Hierarchical linear mixed models identified predictors of cognitive decline with progressive levels of adjustment. There was a decline in processing speed that was explained by race, age, and the 3-way interaction of race, CVH, and time ( F 1,4308 =8.8, P =0.003). CVH was unrelated to decline in White women but in Black women poorer CVH was associated with greater decline. Working memory did not decline in the total cohort, by race, or by CVH., Conclusions: In midlife Black women, CVH promotion may be a target for preventing the beginnings of cognitive decline, thereby enhancing independent living with aging.

In their recent Viewpoint article, Beidas et al. (2023) argue that researchers should test psychosocial interventions in the contexts in which they are meant to be delivered and that they can accelerate the deployment of these interventions by advancing directly from pilot trials to effectiveness and implementation studies without conducting efficacy trials. In this commentary, we argue that this is a well-intended but problematic approach and that there is a more productive strategy for translational behavioral intervention research. The commentary discusses issues concerning intervention development, refinement, and optimization; pilot and efficacy testing of interventions; the contexts in which interventions are delivered; clinical practice guidelines; and quick versus programmatic answers to significant clinical research questions. Testing psychosocial interventions in the contexts in which they are meant to be delivered is a complex task for interventions that are designed to be used in a wide variety of contexts. Nevertheless, interventions can be tested in the contexts in which they are meant to be delivered without sacrificing programmatic intervention development or safety and efficacy testing.

Background: Randomized behavioral clinical trials are the gold standard for evaluating efficacy of a behavioral treatment. However, because participants are generally unblinded to treatment, preference for a specific treatment option can lead to biased results and/or reduced treatment efficacy. The purpose was to describe the relative frequency and correlates of existence of a preference and patient preference for either an in-person group-based or a remote self-directed, lifestyle treatment prior to randomization to one of these treatments., Methods: The Enhanced Lifestyles for Metabolic Syndrome (ELM) trial is a multi-site behavioral clinical trial that compares efficacy of a group-based vs. a self-directed approach to lifestyle change on 2-year remission of the metabolic syndrome. Prior to randomization, participants were asked whether they had a preference for a particular treatment and, if so, which approach they preferred. Baseline data were used for a series of logistic regression models to determine behavioral correlates of treatment preference, independent of socioeconomic factors., Results: Of the 331 participants, 131 (39.6%) had no preference for either treatment. Among the 200 with a preference, 56 (28.0%) preferred the self-directed program. Strength of a pre-existing habit of eating vegetables on most days was an independent correlate of no preference (adjusted OR, 1.27; 95% CI, 1.01-1.61; p = 0.03) and preference for a self-directed program (adjusted OR, 1.55; 95% CI, 1.09-2.22; p = 0.01)., Conclusion: A pre-existing habit of eating vegetables was associated with no preference and preference for a less intensive lifestyle treatment. Post-treatment follow-up of the trial results will determine if concordance between preference and treatment assignment influences outcomes., (© 2024.

Objective: Smoking cessation for individuals with Chronic Obstructive Pulmonary Disease (COPD) is medically critical, but smoking for coping motives is a common barrier., Method: In this evaluation of three treatment components (Mindfulness, Practice Quitting, and Countering Emotional Behaviors), we conducted two studies guided by the ORBIT model. Study 1 was a single-case design experiment (N = 18); Study 2 was a pilot feasibility study (N = 30). In both studies, participants were randomized to receive one of the three treatment modules. Study 1 examined implementation targets, changes in smoking for coping motives, and changes in smoking rate. Study 2 examined overall feasibility and participant-rated acceptability, and changes in smoking rate., Results: Study 1: Treatment implementation targets were met by 3/5 Mindfulness participants, 2/4 Practice Quitting participants, and 0/6 Countering Emotional Behaviors participants. The Practice Quitting condition led to 100% of participants meeting the clinically significant threshold in smoking for coping motives. Incidence of quit attempts ranged from 0-50%, and smoking rate was reduced by 50% overall. Study 2: Recruitment and retention met feasibility targets, with 97% of participants completing all four treatment sessions. Participants reported high treatment satisfaction by qualitative responses and rating scales (M = 4.8/ 5.0). Incidence of quit attempts ranged from 25-58%, and smoking rate was reduced by 56% overall., Conclusions: These two small-N studies provide complementary findings on internal validity and implementation of the novel intervention. While Study 1 provided initial support for plausibility of clinically significant change, Study 2 provided data on key feasibility parameters., Implications: Smoking cessation for individuals with COPD is medically critical. We conducted an early-phase evaluation of a novel behavioral treatment focused on reducing smoking for coping motives. Results provided initial support for plausibility of clinically significant change and feasibility of the intervention., (© 2023.

Men who work in blue-collar occupations (skilled and unskilled trades) experience high rates of obesity and comorbid conditions. This group is underrepresented in behavioral interventions for weight management, which may stem from a mismatch between the features of available programs and these men's preferences. This qualitative study explored the views of these men, their experiences with weight loss, their preferences for weight loss programs, and messaging related to these programs. We conducted remote interviews with 20 men (age: 43 ± 13 years, M ± SD ) currently working in blue-collar occupations (50% construction, 25% transportation, and 25% manufacturing) who had body mass indices (BMIs) in the overweight/obese categories (BMI: 33 ± 6 kg/m 2 ). Deductive codes and summary themes were developed and discussed by the first two authors. A selection of transcripts was reviewed following theme development to confirm accuracy of the themes. Most participants ( n = 16, 80%) reported a prior weight loss attempt. The most common approaches to weight loss reported were increased exercise and following their own approach to changing diet (e.g., "eating less junk food"). For program and message preferences, two major themes emerged: participants wanted accurate and trustworthy information and wanted programs that fit their lifestyle. Results suggest that weight loss programs targeting men working in blue-collar occupations should emphasize the accuracy of information related to the program and the ease of incorporating it into participants' lifestyles. There is an urgent need to incorporate these preferences into effective programs.

Background Prevention of cardiovascular disease (CVD) is a public health priority. The combination of physical activity, a healthy diet, and abstaining from tobacco plays an important role in prevention whereas aspects of psychosocial well-being have largely been examined separately with conflicting results. This study evaluated whether the combination of indices of psychosocial well-being was associated with less progression of coronary artery calcium (CAC). Methods and Results Participants were 312 women (mean age 50.8) from the SWAN (Study of Women's Health Across the Nation) ancillary Heart Study, free of clinical CVD at baseline. A composite psychosocial well-being score was created from 6 validated psychosocial questionnaires assessing optimism, vitality, life engagement, life satisfaction, rewarding multiple roles, and positive affect. Subclinical CAC progression was defined as an increase of ≥10 Agatston units over 2.3 years measured using electron beam tomography. Relative risk (RR) regression models examined the effect of well-being on CAC progression, progressively adjusting for sociodemographic factors, depression, healthy lifestyle behaviors, and standard CVD risk factors. At baseline, 42.9% had a CAC score >0, and progression was observed in 17.6%. Well-being was associated with less progression (RR, 0.909; 95% CI, 0.843-0.979; P =0.012), which remained significant with adjustment for potential confounders, depression, and health behaviors. Further adjustment for standard CVD risk factors weakened the association for the total sample (RR, 0.943; 95% CI, 0.871-1.020; P =0.142) but remained significant for the 134 women with baseline CAC>0 (RR, 0.921; 95% CI, 0.852-0.995; P =0.037). Conclusions Optimum early prevention of CVD in women may result from including the mind side of the mind-heart-body continuum.
