AI Article Synopsis
- African Americans face higher cardiovascular disease mortality compared to White adults due to elevated prevalence of cardiovascular risk factors, but a mobile health intervention has shown promise in improving cardiovascular health in this group.
- A cluster randomized controlled trial in Minnesota involving participants from 16 churches assessed the effectiveness of this culturally tailored mHealth intervention against a delayed control group, focusing on individuals with obesity and other related conditions.
- Results indicated that participants in the intervention group experienced a significant increase in their LS7 cardiovascular health scores, particularly among those with obesity and multiple risk factors, highlighting the intervention's potential impact on enhancing cardiovascular health for African Americans.
Article Abstract
Background: African Americans have a higher prevalence of cardiovascular risk factors, leading to higher cardiovascular disease mortality than White adults. Our culturally tailored mobile health (mHealth) lifestyle intervention () has previously demonstrated efficacy in promoting ideal cardiovascular health in African Americans.
Methods: We conducted a secondary analysis from a cluster randomized controlled trial among African-Americans from 16 churches in Minnesota that compared the to a delayed intervention control group. A subgroup of participants with ≥ 1 diagnosis of overweight/obesity, hyperlipidemia, hypertension, or diabetes was examined. The primary outcome was a change in LS7 score-a measure of cardiovascular health ranging from poor to ideal (range 0-14 points)-at 6-months post-intervention.
Results: The analysis included 49 participants (intervention group: = 20; mean age 58.8 years, 75% female; control group: = 29, mean age 52.5 years, 76% female) with no significant baseline differences in cardiovascular risk factors. Compared to the control group, the intervention group showed a greater increase in LS7 score across all cardiovascular risk factors at 6-months post-intervention, with statistically significant differences among those with overweight/obesity (intervention effect 1.77, < 0.0001) and 2+ or 3+ cardiovascular risk factors (1.00, = 0.03; 1.09, = 0.04). The intervention group demonstrated a higher increase in the percentage of participants with intermediate or ideal LS7 scores than the control group, although these differences were not statistically significant.
Conclusions: Our culturally tailored mHealth lifestyle intervention was associated with significant increases in LS7 scores among African Americans with preexisting cardiovascular risk factors, suggesting its efficacy in improving cardiovascular health among this population.

Among the most pressing problems societies face today are economic inequality and the erosion of democratic norms and institutions. In fact the two problems-inequality and democratic erosion-are linked. In a large cross-national statistical study of risk factors for democratic erosion, we establish that economic inequality is one of the strongest predictors of where and when democracy erodes.

Objective: Aneurysmal subarachnoid hemorrhage (SAH) is associated with high morbidity and mortality rates. In particular, functional outcomes of SAH caused by large or giant (≥ 10 mm) ruptured intracranial aneurysms are worsened by high procedure-related complication rates. However, studies describing the risk factors for poor functional outcomes specific to ruptured large/giant aneurysms are sparse.

Objective: Hand function, an important component of daily functioning, declines with age, yet the degree to which occupation modifies such declines is largely unknown.Methods: Older adults (≥65) completed an online cross-sectional survey containing a standardized hand function questionnaire, occupation-related questions, and demographic information. Participants were then categorized by their longest-held occupation as Blue Collar or White Collar.
