Predicting Home and Work Blood Pressure Measurements from Resting Baselines and Laboratory Reactivity in Black and White Americans

The relationship between blood pressure in the laboratory (both at rest and in response to laboratory tasks) and ambulatory blood pressure at home and at work was evaluated. One hundred nineteen normotensive and unmedicated mild-moderate hypertensive black and white females and males participated in laboratory blood pressure monitoring at rest and during four challenging tasks (structured interview, video game, bicycle exercise, and cold pressor test) as well as ambulatory blood pressure monitoring while at home and at work. Baseline blood pressure taken while subjects were at rest was the strongest predictor of ambulatory systolic blood pressure (r = .64) and diastolic blood pressure (r = .77) at work. Among reactivity tasks the strongest predictors of ambulatory blood pressure in the total population were the structured interview and the video game (both psychological tasks) followed by the cold pressor test. Racial comparisons, however, determined that the cold pressor test predicted diastolic blood pressure significantly better for blacks (r = .73) than for whites (r = .40), suggesting a possible difference in blood pressure regulation.     

The effect of a 1-deoxynojirimycin derivative on post-prandial blood glucose and insulin levels in healthy black and white volunteers

Summary BAY m1099 (a 1-deoxynojirimycin derivative) is a glucose analogue which is an -glucosidase inhibitor. Its effects on post-prandial blood glucose and insulin levels was compared with a placebo in 12 healthy male volunteers (6 Blacks and 6 Whites). It produced a similar, significant depression of post-prandial blood glucose and insulin leveles when the groups were assessed separately and when the data were pooled. Although blood insulin levels in Whites were higher than in Blacks, as previously reported, the difference was not statistically significant and did not appear to influence the response to the drug. BAY 1099 produced no objective or subjective untoward effects and appears to warrant further investigation as an adjuvant to dietary control of diabetes mellitus.     

A Feasibility Study of Smoking Cessation Utilizing an Exercise Intervention among Black Women: ‘Quit and Fit’

BackgroundWomen who engage in higher levels of exercise while trying to quit smoking have been shown to be less likely to relapse and to sustain their smoking abstinence longer. This study sought to examine the benefits of exercise for improving smoking cessation among Black women.MethodsWe evaluated the feasibility of a 12-week smoking and exercise intervention, Quit and Fit, tailored for Black women. All participants (intervention and control) received 12 weeks of smoking cessation counseling via telephone and 9 weeks of nicotine lozenges. Participants who were randomly assigned to the intervention condition were also assigned to a 12-week exercise group.ResultsThirty-eight women were enrolled and 27 completed a 12-week follow-up assessment. Women from the intervention group were more likely to complete the 12-week follow-up assessment compared to participants in the control group (80% vs. 61%). Overall, 7 of the 38 participants (18%) were abstinent at 12 weeks (biochemically verified by expired carbon monoxide). Among the 25 women who completed the 12-week follow-up, abstinence was reported in 33% of the intervention group and 20% of the control group. Using an intent-to-treat approach, 25% of women in the intervention group were abstinent at 12 weeks (n = 5), compared to 11.1% for the control group (n = 2). These differences were not statistically significant.ConclusionsThe overall retention rate was 71% (27/38) at 12 weeks with higher among the intervention group (16/20; 80%) compared to the control group (11/18; 61%). The study demonstrates that it is feasible to retain African-American women in a short-term study of smoking cessation and exercise.     

Psychological interventions for depression and anxiety in pregnant Latina and Black women in the United States: A systematic review

Black women and Latinas have more symptoms of depression and anxiety during pregnancy than do their non‐Latina White counterparts. Although effective interventions targeting internalizing disorders in pregnancy are available, they are primarily tested with White women. This article reviews randomized controlled trials and non‐randomized studies to better understand the effectiveness of psychological interventions for anxiety and depression during pregnancy in Latinas and Black women. Additionally, this review summarizes important characteristics of interventions such as intervention format, treatment modality, and the use of cultural adaptations. Literature searches of relevant research citation databases produced 68 studies; 13 of which were included in the final review. Most studies were excluded because their samples were not majority Latina or Black women or because they did not test an intervention. Of the included studies, three interventions outperformed a control group condition and showed statistically significant reductions in depressive symptoms. An additional two studies showed reductions in depressive symptoms from pretreatment to post‐treatment using non‐controlled designs. The remaining eight studies (seven randomized and one non‐randomized) did not show significant intervention effects. Cognitive behavioral therapy was the modality with most evidence for reducing depressive symptoms in pregnant Black and Latina women. No intervention was found to reduce anxiety symptoms, although only two of the 13 measured anxiety as an outcome. Five studies made cultural adaptations to their treatment protocols. Future studies should strive to better understand the importance of cultural modifications to improve engagement and clinical outcomes with pregnant women receiving treatment for anxiety and depression.     

Mortality Associated with Drug Misuse among Blacks in New York City, 1979–1981

A comparison of age-specific death rates from “drug dependence” (ICD 304) among Blacks and Whites in New York City for 1979–1981 found two distinct patterns of mortality. Blacks have higher levels of mortality which extend from the central adult years into middle age while deaths among Whites are confined largely to the younger years (below 35). Among both racial groups, mortality is much higher for males than for females. When male undercount is “corrected,” the ratios between male and female deaths are smaller. The difference in economic opportunities for Whites and Blacks is suggested as a reason why Whites “age out” of the years of highest risk before Blacks.
