Racial/ethnic differences in social support and health among Asian American and non-Hispanic White midlife women: Results from the Study of Women’s Health Across the Nation (SWAN)

ABSTRACT Objective: Although prior research suggests Asian Americans experience physical health advantages relative to other racial/ethnic groups, increasing evidence points to health inequalities within Asian American subgroups. Disparities are especially pronounced among middle-aged Asian American women, who remain an understudied population, despite studies showing that midlife corresponds with distinct social stressors and changes in the availability of protective resources, such as social support. Thus, the purpose of the study was to examine racial/ethnic differences in social support and self-rated health (SRH) among middle-aged women. Design: With data from the Study of Women’s Health Across the Nation (SWAN; N = 1258), we used modified Poisson regression models to estimate incidence rate ratios (IRR), examining how social support shaped the risk of fair-to-poor SRH by race/ethnicity. We tested interactions between perceived stress, social support and race/ethnicity to determine whether the stress-buffering role of social support varies by group. Results: Results demonstrate racial/ethnic differences in SRH. Higher levels of social support were linked to higher fair-to-poor SRH among Chinese American women (IRR = 1.24; 95% CI [1.02, 1.52]); while greater social support conferred lower risk among White women. Interaction analyses revealed additional nuances in the stress-buffering effects of social support among Chinese American women, such that the health benefits of social support depended on levels of perceived stress (IRR = 0.75; 95% CI [0.57, 1.00]). Conclusions: These findings highlight important distinctions in the ways that psychosocial factors shape health across racial/ethnic groups. In particular, this study helps advance our understanding of important subgroup differences in the stress-buffering role of social support for Asian American midlife women. Interventions should focus on identifying sources of social strain among Asian American women that can increase the risk for poor health and identify alternative sources of support that mitigate stressors to improve health.

Arterial Stiffness Accelerates Within 1 Year of the Final Menstrual Period: The SWAN Heart Study.

Menopause may augment age-dependent increases in arterial stiffness, with black women having greater progression in midlife compared with white women. We sought to determine whether and when women experience changes in arterial stiffness relative to the final menstrual period (FMP) and whether these changes differ between black and white midlife women. Approach and Results: We evaluated 339 participants from the SWAN (Study of Women's Health Across the Nation) Heart Ancillary study (Study of Women's Health Across the Nation). Women had ≤2 carotid-femoral pulse-wave velocity (cfPWV) exams over a mean±SD of 2.3±0.5 years of follow-up. Annual percentage changes in cfPWV were estimated in 3 time segments relative to FMP and compared using piecewise linear mixed-effects models. At baseline, women were 51.1±2.8 years of age and 36% black. Annual percentage change (95% CI) in cfPWV varied by time segments: 0.9% (-0.6% to 2.3%) for >1 year before FMP, 7.5% (4.1% to 11.1%) within 1 year of FMP, and -1.0% (-2.8% to 0.8%) for >1 year after FMP. Annual percentage change in cfPWV within 1 year of FMP was significantly greater than the other 2 time segments; P<0.05 for both comparisons. Adjusting for concurrent cardiovascular disease risk factors explained part of the change estimates but did not eliminate the difference. Black women had greater increase in cfPWV compared with white women in the first segment; P for interaction, 0.04. The interval within 1 year of FMP is a critical period for women when vascular functional alterations occur. These findings underscore the importance of more intensive lifestyle modifications in women transitioning through menopause.

The relationships of multiple factors to menopausal symptoms in different racial/ethnic groups of midlife women: The structural equation modeling

ABSTRACTThe purpose of the present study was to examine the relationships of multiple factors to menopausal symptoms in different racial/ethnic groups of midlife women. This secondary analysis was conducted with the data from 980 midlife women that were collected from 2005 to 2013 using the Midlife Women’s Symptom Index. Structural equation modeling was used to analyze the data. The model had the highest fit indices for non-Hispanic (NH) White midlife women, and prominent racial/ethnic differences were observed in the relationships of multiple factors to menopausal symptoms. In all racial/ethnic groups (except in Hispanic women), perceived health status was significantly positively associated with menopausal symptoms (β = −0.149 for NH African-American; β = −0.207 for NH Asians; β = −0.162 for NH Whites). Body mass index was significantly positively associated with menopausal symptoms only in NH Asians (β = 0.118) and Hispanics (β = 0.210). The racial/ethnic differences in the relationships of multiple factors to menopausal symptoms could have resulted from the different cultural contexts in which women undergo during their menopausal transitions. Further cultural studies on the associations of racial/ethnic-specific factors with menopausal symptoms would help in understanding possible causes for racial/ethnic differences in the factors significantly associated with menopausal symptoms.

Beverage Intake and Metabolic Syndrome Risk Over 14 Years: The Study of Women's Health Across the Nation

BackgroundAlcohol and energy-dense beverages consumption have been implicated in cardiometabolic disease, albeit inconsistently. ObjectiveThis study tested prospective associations between intakes of alcohol, energy-dense beverages, and low-calorie beverages and cardiometabolic risk in midlife women. DesignThe Study of Women’s Health Across the Nation is a 14-year, multisite prospective cohort study (1996-2011). Beverage intake and cardiometabolic risk factors that define the metabolic syndrome (hypertension, abdominal obesity, impaired fasting glucose, low high-density lipoprotein cholesterol level, and hypertriglyceridemia) were assessed throughout follow-up. Participants/settingParticipants (N=1,448) were African American, Chinese, Japanese, and non-Hispanic white midlife women from six US cities. Main outcome measuresThe primary outcomes were incident metabolic syndrome and the individual metabolic syndrome components. Statistical analyses performedGeneralized linear mixed models tested associations between intakes within each beverage category and odds of meeting criteria for metabolic syndrome and each of the metabolic syndrome components. ResultsEnergy-dense beverage consumption was highest among African-American women and lowest among women with college degrees. Non-Hispanic white women consumed the largest quantities of alcohol. Independent of energy intake and potential confounders, each additional 355 mL energy-dense beverages consumed per day was associated with higher odds of developing metabolic syndrome in each successive year of follow-up (odds ratio [OR] 1.05, 95% CI 1.02 to 1.08). Greater energy-dense beverage intake was associated with more rapidly increasing odds of developing hypertension (OR 1.06, 95% CI 1.02 to 1.11) and abdominal obesity (OR 1.10, 95% CI 1.03 to 1.16) over time, but not with the other metabolic syndrome components. Intakes of alcohol and low-calorie coffees, teas, and diet cola were not associated with metabolic syndrome risk. ConclusionsOver 14 years of follow-up, energy-dense nonalcoholic beverage consumption was associated with incident metabolic syndrome in midlife women. The observed differences in intakes by ethnicity/race and education suggest that consumption of these beverages may contribute to disparities in risk factors for diabetes and cardiovascular disease.

Attitudes Toward Physical Activity of White Midlife Women

To explore attitudes toward physical activity of White midlife women in the United States using a feminist perspective. A cross-sectional qualitative study using a thematic analysis. Internet communities for midlife women. Twenty-nine White midlife women in the United States recruited using a convenience sampling method. We used 17 topics on attitudes toward physical activity and ethnic-specific contexts to administer an online forum. We analyzed the data using thematic analysis. We found three themes: thinking without action, gendered and sedentary culture, and motivating myself. The women knew and understood the necessity of physical activity for their physical and mental health but in most cases had not been able to take action to increase their physical activities. Although the culture that circumscribed the women's physical activity was sedentary in nature, the women tried to motivate themselves to increase their physical activities through several creative strategies. The findings strongly suggest that although women were doing their best, American culture itself needs to be changed to help women increase physical activity in their daily lives.

Menopausal symptom experience: an online forum study

The aim of the study was to explore the menopausal symptom experience of White midlife women. Recent cross-cultural investigations have indicated important ethnic differences in menopausal symptoms and have challenged the universality of these symptoms. Currently available cultural knowledge on menopausal experience, however, is inadequate to guide appropriate and adequate care even for White women in the menopausal transition. A cross-sectional qualitative online forum study was conducted in 2007 with 23 midlife women who self-identified as non-Hispanic Whites using convenience sampling. Seven topics related to menopausal symptom experience were used to guide the online forum for 6 months. The data were analysed using thematic analysis. The experiences of menopause caused women to redefine themselves within their busy daily life schedules. They were optimistic about their symptoms, and tried to laugh at the experience to boost their inner strength and motivate themselves to persevere. Many thought that both generational and life-style differences were much more important than ethnic differences in menopausal symptom experiences. In seeking assistance with the symptoms of menopause, women were not satisfied with the guidance of their physicians. Nurses need to listen carefully to what women themselves say about their own experiences with menopausal symptoms and avoid imposing predetermined symptom management strategies. Further studies of women's perceptions of life-style influences are needed to guide symptom management. In addition, studies of generational changes in menopausal symptom experience are needed.
