ABSTRACT
Context: There are no reported data from prospective long-term studies on the relation of androgen levels in young women with development of metabolic syndrome (MetS) before menopause. Objective: We investigated associations of androgens and SHBG with incident MetS during 23 years of follow-up. Methods: We included 366 White and 375 Black women ages 20 to 32 years participating in the CARDIA study and CARDIA Women's study, free of MetS at baseline examination (1987-1988), and premenopausal 23 years later. Androgens and SHBG were categorized into quartiles. MetS was defined according to the American Heart Association/National Heart, Lung, and Blood Institute 2009 Joint Scientific Statement. Cox proportional hazards models were used. Results: By year 23, 30% of women developed MetS. Adjusting for baseline age, race, and education, hazard ratios (95% CI) of developing MetS were 1.46 (1.02-2.10) and 2.22 (1.53-3.21) for women in the highest vs lowest total testosterone (T) and free T quartile, respectively. The hazards of developing MetS were 47%, 59%, and 53% lower for women with SHBG in the second, third, and fourth quartiles (vs lowest quartile), respectively. Associations were attenuated for total T with further adjustments for smoking, physical activity, menstrual status, oral contraceptive/hormone (OCHM) use, insulin level, oligomenorrhea, and age at menarche, but remained statistically significant for free T and SHBG. Associations were similar for both Blacks and Whites, and OCHM nonusers, but not for OCHM users. Conclusion: High androgenicity in young premenopausal women is associated with higher risk of future MetS, suggesting that early assessment of androgens may contribute to prevention.
ABSTRACT
BACKGROUND: Current evidence supports the adoption of healthy diet and physical activity (PA) behaviors in patients with polycystic ovary syndrome (PCOS), given the positive effects of those behaviors on physical well-being. An improved understanding of the associations between diet and PA with PCOS is needed to ascertain whether tailored dietary and PA recommendations are needed for this population. Thus, we investigated the associations of diet and PA with PCOS and its isolated features. METHODS: Cross-sectional study. Of the 748 women who were included in this study from the Coronary Artery Risk Development in Young Adults (CARDIA) Women's Study, 40 were classified as having PCOS, 104 had isolated hyperandrogenism (HA) and 75 had isolated oligomenorrhea (OA). Dietary intake was measured using the CARDIA diet history questionnaire and diet quality was scored using the Alternative Healthy Eating Index 2010; a higher score indicated a better quality diet. Self-reported PA was measured using a validated interviewer-administered questionnaire. Polytomous logistic regression analyses examined the associations between diet and PA with PCOS, HA, and OA status (outcomes), adjusting for age, race, total energy intake, education, and/or body mass index. The threshold for statistical significance was set at p < 0.05. RESULTS: Mean age of the participants was 25.4 years (SD 3.6) and 46.8% of participants were Black women. There was little to no association of total energy intake, nutrients, diet quality, and PA with PCOS, HA or OA status. CONCLUSION: Energy intake, nutrient composition, diet quality, and PA were not associated with PCOS, supporting recent PCOS guidelines of using national recommendations for the general population to encourage health-promoting behaviors among women with PCOS. However, longitudinal studies evaluating changes in diet and physical activity in relation to the development and/or the progression of PCOS are needed to establish a causal association.

Social stratification is an important mechanism of human organization that helps to explain health differences between demographic groups commonly associated with socioeconomic gradients. Individuals, or group of individuals, with similar health profiles may have had different stratification experiences. This is particularly true as social stratification is a significant non-measurable source of systematic unobservable differences in both SES indicators and health statuses of disadvantage. The goal of the present study was to expand the bulk of research that has traditionally treated socioeconomic and demographic characteristics as independent, additive influences on health by examining data from the United States. It is hypothesized that variation in an index of multi-system physiological dysregulation - allostatic load - is associated with social differentiation factors, sorting individuals with similar demographic and socioeconomic characteristics into mutually exclusive econo-demographic classes. The data were from the Longitudinal and Biomarker samples of the national Study of Midlife Development in the US (MIDUS) conducted in 1995 and 2004/2006. Latent class analyses and regression analyses revealed that physiological dysregulation linked to socioeconomic variation among black people, females and older adults are associated with forces of stratification that confound socioeconomic and demographic indicators. In the United States, racial stratification of health is intrinsically related to the degree to which black people in general, and black females in particular, as a group, share an isolated status in society. Findings present evidence that disparities in health emerge from group-differentiation processes to the degree that individuals are distinctly exposed to the ecological, political, social, economic and historical contexts in which social stratification is ingrained. Given that health policies and programmes emanate from said legal and political environments, interventions should target the structural conditions that expose different subgroups to different stress risks in the first place.

As many as 50% of people satisfying diagnostic criteria for dementia are undiagnosed. A team-based training program for dementia screening and management was developed targeting four professions (medicine, nursing, pharmacy, social work) whose scope of practice involves dementia care. An interprofessional group of 10 faculty members was trained to facilitate four interactive competency stations on dementia screening, differential diagnoses, dementia management and team care planning, and screening for and managing caregiver stress. Registrants were organized into teams of five members, with at least one member of each profession per team. The teams rotated through all stations, completing assigned tasks through interprofessional collaboration. A total of 117 professionals (51 physicians, 11 nurses, 20 pharmacists, 24 social workers, 11 others) successfully completed the program. Change scores showed significant improvements in overall competence in dementia assessment and intervention (very low = 1; very high = 5; average change 1.12, P < .001), awareness of importance of dementia screening (average change 0.85, P < .001), and confidence in managing medication (average change 0.86, P < .001). Eighty-seven participants (82.9%) reported feeling confident or very confident using the dementia toolkit at their home institution. In a survey administered 3 months after the session, 48 respondents reported that they had changed their approach to administering the Mini-Cog test (78%), differential diagnosis (49%), assessment of caregiver stress (74%), and accessing community support and services (69%). In conclusion, team-based interprofessional competency training is a team teaching model that can be used to enhance competency in dementia screening and management in medical, nursing, pharmacy, and social work practitioners.

Depression is common in nursing facility residents. Depression data obtained using the Minimum Data Set (MDS) 3.0 offer opportunities for improving diagnostic accuracy and care quality. How best to integrate MDS 3.0 and other data into quality improvement (QI) activity is untested. The objective was to increase nursing home (NH) capability in using QI processes and to improve depression assessment and management through focused mentorship and team building. This was a 6-month intervention with five components: facilitated collection of MDS 3.0 nine-item Patient Health Questionnaire (PHQ-9) and medication data for diagnostic interpretation; education and modeling on QI approaches, team building, and nonpharmacological depression care; mentored team meetings; educational webinars; and technical assistance. PHQ-9 and medication data were collected at baseline and 6 and 9 months. Progress was measured using team participation measures, attitude and care process self-appraisal, mentor assessments, and resident depression outcomes. Five NHs established interprofessional teams that included nursing (44.1%), social work (20.6%), physicians (8.8%), and other disciplines (26.5%). Members participated in 61% of eight offered educational meetings (three onsite mentored team meetings and five webinars). Competency self-ratings improved on four depression care measures (P = .05 to <.001). Mentors observed improvement in team process and enthusiasm during team meetings. For 336 residents with PHQ-9 and medication data, depression scores did not change while medication use declined, from 37.2% of residents at baseline to 31.0% at 9 months (P < .001). This structured mentoring program improved care processes, achieved medication reductions, and was well received. Application to other NH-prevalent syndromes is possible.

OBJECTIVE: To study the independent associations of polycystic ovary syndrome (PCOS), and its 2 components, hyperandrogenism and anovulation, with coronary artery calcification (CAC) and carotid artery intima-media thickness (IMT). APPROACH AND RESULTS: At the year 20 of the Coronary Artery Risk Development in Young Adults (CARDIA) study, a population-based multicenter cohort of young adults, women (mean age, 45 years) with information on menses and hirsutism in their twenties were assessed for CAC (n=982) and IMT (n=988). We defined PCOS as women who had both irregular menses and hyperandrogenism (n=55); isolated oligomenorrhea (n=103) as women who only had irregular menses; and isolated hyperandrogenism (n=156) as women who had either hirsutism or increased testosterone levels. Logistic regressions and general linear models were used to estimate the associations between components of PCOS and subclinical CVD. The prevalence of CAC was 10.3% overall. Women with PCOS had a multivariable adjusted odds ratio of 2.70 (95% confidence interval, 1.31-5.60) for CAC. Women with either isolated oligomenorrhea or isolated hyperandrogenism had no increased risk of CAC when compared with unexposed women. Women with PCOS had significantly increased bulb and internal carotid-IMT measurements; however, no significant differences were noted in bulb or internal carotid artery IMT among women with either isolated oligomenorrhea or isolated hyperandrogenism when compared with unexposed women. There were no differences in common carotid-IMT among the 4 study groups. CONCLUSIONS: In this study, women with PCOS, manifested as both anovulation and hyperandrogenism, but not women with one of these manifestations alone, were at increased risk for the development of subclinical CVD.

PURPOSE: Bone acquisition in childhood impacts adult bone mass, and can be influenced by childhood socioeconomic conditions. Socioeconomic status is also associated with body weight which affects the load that bone is exposed to in a fall. We hypothesized that socioeconomic advantage in childhood is associated with greater bone strength relative to load in adulthood. METHODS: Hip dual x-ray absorptiometry scans from 722 participants in the Midlife in the United States Study were used to measure femoral neck size and bone mineral density, and combined with body weight and height to create composite indices of femoral neck strength relative to load in different failure modes: compression, bending, and impact. A childhood socioeconomic advantage score was created for the same participants from parental education, self-rated financial status relative to others, and not being on welfare. Multiple linear regression was used to determine the association of childhood socioeconomic advantage with femoral neck composite strength indices, stratified by gender and race (white/non-white), and adjusted for study site, age, menopause status in women, education, and current financial advantage. RESULTS: Childhood socioeconomic advantage was independently associated with higher indices of all three composite strength indices in white men (adjusted standardized effect sizes, 0.19 to 0.27, all p values<0.01), but not in the other three race/gender groups. Additional adjustment for adult obesity, physical activity in different life stages, smoking, and heavy drinking over the life-course significantly attenuated the associations in white men. CONCLUSIONS: Socioeconomic disadvantage in childhood is associated with lower hip strength relative to load in white men, and these influences are dampened by healthy lifestyle choices.

This article updates trends from five national U.S. surveys to determine whether the prevalence of activity limitations among the older population continued to decline in the first decade of the twenty-first century. Findings across studies suggest that personal care and domestic activity limitations may have continued to decline for those ages 85 and older from 2000 to 2008, but generally were flat since 2000 for those ages 65-84. Modest increases were observed for the 55- to 64-year-old group approaching late life, although prevalence remained low for this age group. Inclusion of the institutional population is important for assessing trends among those ages 85 and older in particular.

OBJECTIVE: To investigate the association between salivary cortisol and two markers of subclinical cardiovascular disease (CVD), coronary calcification (CAC), and ankle-brachial index (ABI). METHODS: Data from an ancillary study to the Multi-Ethnic Study of Atherosclerosis (MESA), the MESA Stress Study, were used to analyze associations of salivary cortisol data collected six times per day over three days with CAC and ABI. The authors used mixed models with repeat cortisol measures nested within persons to determine if specific features of the cortisol profile were associated with CAC and ABI. RESULTS: A total of 464 participants were included in the CAC analysis and 610 in the ABI analysis. The mean age of participants was 65.6 years. A 1-unit increase in log coronary calcium was associated with a 1.77% flatter early decline in cortisol (95% CI: 0.23, 3.34) among men and women combined. Among women low ABI was associated with a steeper early decline (-13.95% CI: -25.58, -3.39) and a marginally statistically significant flatter late decline (1.39% CI: -0.009, 2.81). The cortisol area under the curve and wake to bedtime slope were not associated with subclinical CVD. CONCLUSIONS: This study provides weak support for the link between cortisol and measures of subclinical atherosclerosis. We found an association between some features of the diurnal cortisol profile and coronary calcification and ABI but associations were not consistent across subclinical measures. There are methodological challenges in detecting associations of cortisol measures at a point in time with health outcomes that develop over a lifetime. Studies of short-term mechanisms linking stress to physiological processes related to the development of early atherosclerosis may be more informative.

OBJECTIVE: To estimate whether women aged 20-32 years who fulfilled National Institutes of Health criteria for polycystic ovary syndrome (PCOS) would be at higher risk for subsequent development of incident diabetes, dyslipidemia, and hypertension, and to estimate whether normal-weight women with PCOS would have the same degree of cardiovascular risk as overweight women with PCOS. METHODS: We estimated the association of PCOS with incident diabetes, dyslipidemia, and hypertension over a period of 18 years among 1,127 white and African-American women in the Coronary Artery Risk Development in Young Adults cohort. We classified women at baseline (ages 20-32 years) based on self-reported symptoms and serum androgen measures using National Institutes of Health PCOS criteria. We estimated the association of PCOS and subsequent cardiovascular risk factors, independent of baseline body mass index (BMI), using multivariable logistic regression. Additionally, among 746 women with a second assessment of PCOS at ages 34-46 years, we estimated the association of persistent PCOS with cardiovascular risk factors. RESULTS: Of 1,127 women, 53 (4.7%) met criteria for PCOS at ages 20-32 years. Polycystic ovary syndrome was associated with a twofold higher odds of incident diabetes (23.1% compared with 13.1%, adjusted odds ratio [AOR] 2.4, confidence interval [CI] 1.2-4.9) and dyslipidemia (41.9% compared with 27.7%, AOR 1.9, CI 1.0-3.6) over the course of 18 years; the association with incident hypertension was not significant (26.9% compared with 26.3%, AOR 1.7, CI 0.8-3.3). Normal-weight women with PCOS (n=31) had a threefold higher odds of incident diabetes compared with normal-weight women without PCOS (AOR 3.1, CI 1.2-8.0). Compared with those without PCOS, women with persistent PCOS (n=11) had the highest odds of diabetes (AOR 7.2, CI 1.1-46.5). CONCLUSION: Polycystic ovary syndrome is associated with subsequent incident diabetes and dyslipidemia, independent of BMI. Diabetes risk may be greatest for women with persistent PCOS symptoms. LEVEL OF EVIDENCE: II.

OBJECTIVES: We investigated trends in disability among older Americans from 1988 through 2004 to test the hypothesis that more recent cohorts show increased burdens of disability. METHODS: We used data from 2 National Health and Nutrition Examination Surveys (1988-1994 and 1999-2004) to assess time trends in basic activities of daily living, instrumental activities, mobility, and functional limitations for adults aged 60 years and older. We assessed whether changes could be explained by sociodemographic, body weight, or behavioral factors. RESULTS: With the exception of functional limitations, significant increases in each type of disability were seen over time among respondents aged 60 to 69 years, independent of sociodemographic characteristics, health status, relative weight, and health behaviors. Significantly greater increases occurred among non-Whites and persons who were obese or overweight (2 of the fastest-growing subgroups within this population). We detected no significant trends among respondents aged 70 to 79 years; in the oldest group (aged>or=80 years), time trends suggested lower prevalence of functional limitations among more recent cohorts. CONCLUSIONS: Our results have significant and sobering implications: older Americans face increased disability, and society faces increased costs to meet the health care needs of these disabled Americans.

Data from the nationally representative US National Health and Nutrition Examination Survey (NHANES) III cohort were used to examine the hypothesis that socio-economic status is consistently and negatively associated with levels of biological risk, as measured by nine biological parameters known to predict health risks (diastolic and systolic blood pressure, pulse, HDL and total cholesterol, glycosylated hemoglobin, c-reactive protein, albumin and waist-hip ratio), resulting in greater cumulative burdens of biological risk among those of lower education and/or income. As hypothesized, consistent education and income gradients were seen for biological parameters reflecting cardiovascular, metabolic and inflammatory risk: those with lower education and income exhibiting greater prevalence of high-risk values for each of nine individual biological risk factors. Significant education and income gradients were also seen for summary indices reflecting cumulative burdens of cardiovascular, metabolic and inflammatory risks as well as overall total biological risks. Multivariable cumulative logistic regression models revealed that the education and income effects were each independently and negatively associated with cumulative biological risks, and that these effects remained significant independent of age, gender, ethnicity and lifestyle factors such as smoking and physical activity. There were no significant ethnic differences in the patterns of association between socio-economic status and biological risks, but older age was associated with significantly weaker education and income gradients.
