Background: Greater abdominal adiposity is associated with insulin resistance and obesity-related vascular disease. Physical activity (PA) is inversely associated with abdominal adiposity yet associations between trends in adherence to PA recommendations through young adulthood and abdominal adiposity in middle age is unclear. Objective: To identify common trajectories of maintaining recommended levels of PA through young adulthood and to examine associations between trajectories and abdominal adiposity at middle age. Methods: The Coronary Artery Risk Development in Young Adults (CARDIA) study is a population-based, prospective, observational study of black and white men and women. PA was assessed at 8 exams across 25 years of follow-up. PA trajectories were identified by group-based modeling (PROC TRAJ) based on likelihood of maintaining recommended PA levels across exams. Visceral, subcutaneous, and abdominal intermuscular adipose tissue volumes (cm3) were assessed by computed tomography at the year 25 exam (43-55 yrs, n=3180). Results: Four major PA trajectories were identified: highly active (27.3%), declining activity (18.2%), modestly active (20.7%) and always sedentary (33.8%). Abdominal adipose tissue volumes by PA trajectory, race, and sex are displayed in Figure 1. Among white men and women, abdominal adiposity was lowest in always active adults and highest in those always sedentary; higher abdominal adiposity was observed with declining activity compared to modest activity. In black women, highest levels of abdominal adiposity were observed with declining activity. Black men exhibited no differences in abdominal adiposity across PA trajectory groups. Conclusions: Maintaining recommended physical activity levels through young adulthood is associated with lower abdominal adiposity at middle age. Highly active adults who exhibit declining physical activity towards middle age exhibit higher abdominal adiposity compared to adults with consistent modest activity throughout adulthood.

Background: Excess visceral adiposity tissue (VAT) is associated with elevated free fatty acids that contribute to dyslipidemia, beta cell dysfunction, and insulin resistance. Greater physical activity (PA) is associated with lower VAT cross-sectionally, but whether PA during young adulthood is associated with VAT at middle age independent of general obesity is unclear. Objective: To quantify by sex and race the associations between PA levels in young adulthood with visceral adiposity measured 25 years later. Methods: The Coronary Artery Risk Development in Young Adults (CARDIA) study is a population-based, prospective, observational study of black and white men and women. Habitual PA was determined as the average of baseline and year 7 levels (18–37 yrs) of the CARDIA Physical Activity Score. VAT (cm3) was assessed by computed tomography at the year 25 exam (43–55 yrs, n=1822). Results: Early adulthood PA levels were 15.2% lower in blacks compared to whites (p<0.001) and 30.0% lower in women compared to men (p<0.001); the lowest PA levels were observed in black women. Compared with the highest levels of PA, participants with moderate or lower PA during young adulthood exhibited higher VAT at middle age in linear regression models adjusted for covariates including year 25 BMI (Table 1). When stratified by race and sex, white men and women with higher PA levels exhibited lower VAT at middle age compared to white adults with moderate or lower PA; an association not observed in black men or women. Conclusions: White men and women engaging in higher PA levels at earlier ages may demonstrate lower visceral adiposity later in life, yet these findings suggest that PA may not be a solely effective approach at reducing/preventing cardiometabolic risk from excess visceral adiposity in black adults. Racial variations in the influence of young adulthood PA on visceral adiposity at middle age may reflect differential influences of PA, PA intensity, or other unmeasured risk factors (e.g., psychosocial stress) on adiposity distribution.

Two separate studies investigated race and sex differences in normal auditory sensitivity. Study I measured thresholds at 500, 1000, and 2000 cps of 23 white men, 26 white women, 21 negro men, and 24 negro women using the method of limits. In Study II thresholds of 10 white men, 10 white women, 10 negro men, and 10 negro women were measured at 1000 cps using four different stimulus conditions and the method of adjustment by means of Bekesy audiometry. Results indicated that the white men and women in Study I heard significantly better than their negro counterparts at 1000 and 2000 cps. There were no significant differences between the average thresholds measured at 1000 cps of the white and negro men in Study II. White women produced better auditory thresholds with three stimulus conditions and significantly more sensitive thresholds with the slow pulsed stimulus than did the negro women in Study II.

The Impact

<b><i>Background:</i></b> Age-related changes in biological processes such as physiological dysregulation (the progressive loss of homeostatic capacity) vary considerably among older adults and may influence health profiles in late life. These differences could be related, at least in part, to the impact of intrinsic and extrinsic factors such as sex and physical activity level (PAL). <b><i>Objectives:</i></b> The objectives of this study were (1) to assess the magnitude and rate of changes in physiologi­cal dysregulation in men and women according to PAL and (2) to determine whether/how sex and PAL mediate the apparent influence of physiological dysregulation on health outcomes (frailty and mortality). <b><i>Methods:</i></b> We used data on 1,754 community-dwelling older adults (age = 74.4 ± 4.2 years; women = 52.4%) of the Quebec NuAge cohort study. Physiological dysregulation was calculated based on Mahalanobis distance of 31 biomarkers regrouped into 5 systems: oxygen transport, liver/kidney function, leukopoiesis, micronutrients, and lipids. <b><i>Results:</i></b> As expected, mean physiological dysregulation significantly increased with age while PAL decreased. For the same age and PAL, men showed higher levels of physiological dysregulation globally in 3 systems: oxygen transport, liver/kidney function, and leukopoiesis. Men also showed faster global physiological dysregulation in the liver/kidney and leukopoiesis systems. Overall, high PAL was associated with lower level and slower rate of change of physiological dysregulation. Finally, while mortality and frailty risk significantly increased with physiological dysregulation, there was no evidence for differences in these effects between sexes and PAL. <b><i>Conclusion:</i></b> Our results showed that both sex and PAL have a significant effect on physiological dysregulation levels and rates of change. Also, although a higher PAL was associated with lower level and slower rate of change of physiological dysregulation, there was no evidence that PAL attenuates the effect of physiological dysregulation on subsequent declines in health at the end of life. Substantial work remains to understand how modifiable behaviors impact the relationship between physiological dysregulation, frailty, and mortality in men and women.
