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.

Hazard Functions

Mathematical modeling of cancer development is aimed at assessing the risk factors leading to cancer. Aging is a common risk factor for all adult cancers. The risk of getting cancer in aging is presented by a hazard function that can be estimated from the observed incidence rates collected in cancer registries. Recent analyses of the SEER database show that the cancer hazard function initially increases with the age, and then it turns over and falls at the end of the lifetime. Such behavior of the hazard function is poorly modeled by the exponential or compound exponential-linear functions mainly utilized for the modeling. In this work, for mathematical modeling of cancer hazards, we proposed to use the Weibull-like function, derived from the Armitage-Doll multistage concept of carcinogenesis and an assumption that number of clones at age t developed from mutated cells follows the Poisson distribution. This function is characterized by three parameters, two of which ( r and λ) are the conventional parameters of the Weibull probability distribution function, and an additional parameter ( C0) that adjusts the model to the observational data. Biological meanings of these parameters are: r—the number of stages in carcinogenesis, λ—an average number of clones developed from the mutated cells during the first year of carcinogenesis, and C0—a data adjustment parameter that characterizes a fraction of the age-specific population that will get this cancer in their lifetime. To test the validity of the proposed model, the nonlinear regression analysis was performed for the lung cancer (LC) data, collected in the SEER 9 database for white men and women during 1975–2004. Obtained results suggest that: (i) modeling can be improved by the use of another parameter A- the age at the beginning of carcinogenesis; and (ii) in white men and women, the processes of LC carcinogenesis vary by A and C0, while the corresponding values of r and λ are nearly the same. Overall, the proposed Weibull-like model provides an excellent fit of the estimates of the LC hazard function in aging. It is expected that the Weibull-like model can be applicable to fit estimates of hazard functions of other adult cancers as well.

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: The effect of retirement on cognitive functioning is not clear. We examined the association between age at retirement, midlife occupation, and cognitive decline in the large Atherosclerosis Risk in Communities (ARIC) biracial community-based cohort. Methods: Retirement status after ARIC visit 4 (1996-98) was reported in annual follow-up questionnaires administered in 1999-2007 (n= 8,426), and classified as occurring before or after age 70. Current or most recent occupation at visit 1 (1987-89) was categorized based on 1980 US census major occupation groups and tertiles of Nam-Powers-Boyd occupational status score (a measure of socioeconomic status of occupations, hereby used as a proxy for occupational complexity). Generalized estimating equation models were used to examine the associations of retirement with trajectories of a global cognitive factor score, assessed in 1990-92 (visit 2), 1996-98 (visit 4) and 2011-2013 (visit 5). Models were a priori stratified by race and sex and adjusted for demographics and comorbidities. To account for attrition, we also performed multiple imputation by chained equations. Results: Retirement before age 70 is associated with higher educational level and higher occupational status score in white men and women, and in black men. We observed associations between retirement before age 70 and lower baseline cognitive scores, as well as slower cognitive decline in white men and women, and in black men (Figure). The results did not change substantially after adjusting for the occupational status score or accounting for attrition. Conclusion: Retirement before age 70 was significantly associated with lower baseline cognitive scores and slower cognitive decline in whites and in black men. The lack of similar associations in black women and the investigation of reasons for the observed associations warrant further research.

Background: Atrial fibrillation (AF) is the most common dysrhythmia in clinical practice, and is a significant contributor to morbidity and mortality. Prior reports have projected a large increase in AF burden over time. A contemporary assessment of epidemiology is needed to assess if an emphasis of prevention strategies over the last decade has been effective in alleviating this risk. Methods: We used a 5% national sample of all Medicare beneficiaries in the US from 2002 through 2013 to construct a longitudinal cohort of 2.3 million fee-for-service Medicare beneficiaries administratively followed for ≥2 years using claims data. Trends in incident and prevalent AF were assessed for 2004 through 2013. Using ICD-9 codes, encounters with AF were identified from inpatient, outpatient, and physician claims. AF during the first 2 years of entry into the cohort was defined as pre-existing AF. Incident AF was defined as having either 1 inpatient claim with a diagnosis of AF or 2 outpatient or physician claims with AF. Calendar-year prevalence comprised pre-existing and incident AF for the respective years as well as those with incident AF in preceding years. Age-adjusted time trends were assessed using Poisson regression. Results: Between 2002 and 2013, 219,570 patients had incident AF. At incidence, mean age was 79 years, 55% were women, and 92% and 5% were white and black, respectively. Age-adjusted AF incidence decreased by 0.4/1000 per year between 2004 (20/1000) and 2013 (17/1000). While incidence declined for white men and women (P<.05), it has remained unchanged for black men and women (Figure). Proportion of incident events in the outpatient setting increased from 26% to 40%. One-year mortality was 9%, and remained unchanged throughout the study period. Over this period, the overall prevalence of AF decreased by 0.9/1000 per year (p<.05), however, there was a relative increase in AF prevalence among black men. Conclusions: Between years 2004 and 2013, the overall incidence and prevalence of AF among a 5% sample of Medicare beneficiaries stabilized. There were, however, differences across racial groups, with a slight decline in incidence among white men and women, which was not observed in black men and women.

Because of the West’s scarce labor situation, hop growers early on recognized the need to hire workers from all walks of life, including men and women, old and young, and across racial and ethnic lines. From the beginning, the three-week hop harvest was a multicultural affair that revealed the diversity of the West. The first half of this chapter explains the English origins of the American harvest season, including the actual demands and the festiveness of the harvest that many called a paid vacation. The second half of the chapter explains the opportunities and challenges that American Indian and East Asian agricultural workers faced while working in the Pacific Northwest hopyards during the late nineteenth and early twentieth centuries.

Background: Atrial fibrillation (AF) is the most common sustained arrhythmia in adults and the prevalence is increasing due to the aging of the population and the growing burden of vascular risk factors. Although deaths due to cardiovascular disease (CVD) death have dramatically decreased in recent years, trends in AF-related CVD death has not been previously investigated. Purpose: We sought to quantify trends in AF-related CVD death rates in the United States. Methods: AF-related CVD death was ascertained using the CDC WONDER online database. AF-related CVD deaths were identified by listing CVD (I00-I78) as underlying cause of death and AF (I48) as contributing cause of death among persons aged 35 to 84 years. We calculated age-adjusted mortality rates (AAMR) per 100,000 population, and examined trends over time estimating average annual percent change (AAPC) using Joinpoint Regression Program (National Cancer Institute). Subgroup analyses were performed to compare AAMRs by sex-race (black and white men and women) and across two age groups (younger: 35-64 years, older 65-84 years). Results: A total of 522,104 AF-related CVD deaths were identified between 1999 and 2017. AAMR increased from 16.0 to 22.2 per 100,000 from 1999 to 2017 with an acceleration following an inflection point in 2009. AAPC before 2009 was significantly lower than that after 2009 [0.4% (95% CI, 0.0 - 0.7) vs 3.5% (95% CI, 3.1 - 3.9), p < 0.001). The increase of AAMR was observed across black and white men and women overall and in both age groups (FIGURE), with a more pronounced increase in black men and white men. Black men had the highest AAMR among the younger decedents, whereas white men had the highest AAMR among the older decedents. Conclusion: This study revealed that death rate for AF-related CVD has increased over the last two decades and that there are greater black-white disparities in younger decedents (<65 years). Targeting equitable risk factor reduction that predisposes to AF and CVD mortality is needed to reduce observed health inequities.
