Bad marriage, broken heart? Age and gender differences in the link between marital quality and cardiovascular risks among older adults

Gender Differences in the Link Between Marital Status and the Risk of Cognitive Impairment: Results From the Korean Longitudinal Study of Aging

In the context of South Korea, characterized by increasing population aging and a changing family structure, this study examined differences in the risk of cognitive impairment by marital status and investigated whether this association differs by gender. The data were derived from the 2006-2018 Korean Longitudinal Study of Aging. The sample comprised 7,568 respondents aged 45 years or older, who contributed 30,414 person-year observations. Event history analysis was used to predict the odds of cognitive impairment by marital status and gender. Relative to their married counterparts, never-married and divorced people were the most disadvantaged in terms of cognitive health. In addition, the association between marital status and cognitive impairment was much stronger for men than for women. Further, gender-stratified analyses showed that, compared with married men, never-married men had a higher risk of cognitive impairment, but there were no significant effects of marital status for women.

Assessment of Modifiable Factors for the Association of Marital Status With Cancer-Specific Survival

IMPORTANCE

Married patients with cancer have better cancer-specific survival than unmarried patients. Increasing the early diagnosis and definitive treatment of cancer among unmarried patients may reduce the survival gap.

OBJECTIVES

To evaluate the extent to which marriage is associated with cancer-specific survival, stage at diagnosis, and treatment among patients with 9 common solid cancers and to recommend methods for reducing the survival gap.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective, population-based cohort study included patients older than 18 years who were diagnosed with 1 of 9 common cancers between January 1, 2007, and December 31, 2016. Patient data were retrieved from the Surveillance, Epidemiology, and End Results Program. Statistical analyses were performed from August 1 to October 1, 2020.

EXPOSURES

Marital status, classified as married and unmarried (including single, separated, divorced, widowed, and unmarried patients or domestic partners).

MAIN OUTCOMES AND MEASURES

The primary outcome was the time ratio (TR) of cancer-specific survival (married vs unmarried). Mediation analyses were conducted to determine the extent to which the association of marriage with cancer-specific survival was mediated by stage at diagnosis and treatment.

RESULTS

This study included 1 733 906 patients (894 379 [51.6%] women; 1 067 726 [61.6%] married; mean [SD] age, 63.76 [12.60] years). Multivariate analyses found that those who were married were associated with better cancer-specific survival than unmarried patients (TR, 1.36; 95% CI, 1.35-1.37). Early diagnosis in breast cancer, colorectal cancer, endometrial cancer, and melanoma mediated the association between marital status and cancer-specific survival (breast cancer: proportion mediated [PM], 11.4%; 95% CI, 11.2%-11.6%; colorectal cancer: PM, 10.9%; 95% CI, 10.7%-11.2%; endometrial cancer: PM, 12.9%; 95% CI, 12.5%-13.3%; melanoma: PM, 12.0%; 95% CI, 11.7-12.4%). Surgery mediated the association between marital status and cancer-specific survival in lung (PM, 52.2%; 95% CI, 51.9%-52.4%), pancreatic (PM, 28.9%; 95% CI, 28.6%-29.3%), and prostate (PM, 39.3%; 95% CI, 39.0%-39.6%) cancers. Chemotherapy mediated the association of marital status with cancer-specific survival in lung (PM, 37.7%; 95% CI, 37.6%-37.9%) and pancreatic (PM, 28.6%; 95% CI, 28.4%-28.9%) cancers. Improved cancer-specific survival associated with marriage was greater among men than women (men: TR, 1.27; 95% CI, 1.25-1.28; women: TR, 1.20; 95% CI, 1.19-1.21). The contribution of receiving an early diagnosis and treatment with surgery or chemotherapy to the association between marital status and cancer-specific survival was greater among men than women (early diagnosis: PM, 21.7% [95% CI, 21.5%-21.9%] vs PM, 20.3% [95% CI, 20.2%-20.4%]; surgery: PM, 26.6% [95% CI, 26.4%-26.7%] vs PM, 11.1% [95% CI, 11.0%-11.2%]; chemotherapy: PM, 6.8% [95% CI, 6.7%-6.8%] vs PM, 5.1% [95% CI, 5.0%-5.2%]).

CONCLUSIONS AND RELEVANCE

In this study, survival disparities associated with marital status were attributable to early diagnosis in breast, colorectal, and endometrial cancers as well as melanoma and to treatment-related variables in lung, pancreatic, and prostate cancers. The findings also suggest that marriage may play a greater protective role in the cancer-specific survival of men than of women.

Sexual Obligation and Perceived Stress: A National Longitudinal Study of Older Adults

Objectives: This study examines the relationship between sexual obligation and perceived stress among older adults in the United States.Methods: Using longitudinal data from three waves of the National Social Life, Health, and Aging Project (NSHAP), our sample included 1,477 partnered, sexually-active respondents aged 57 to 85 at the baseline survey. We estimated mixed-effects models to test how feelings of sexual obligation are related to changes in perceived stress score.Results: Sexual obligation was positively associated with perceived stress score. The positive relationship between sexual obligation and perceived stress score became stronger over the study period among older men, although it remained relatively stable among older women. Relationship quality only partially explains this relationship.Conclusions: Feeling more obligated to have sex had a significantly greater effect on older men's perceived level of stress over time than older women's. This association became marginally significant after relationship quality was controlled for, suggesting that relationship quality was a key explanatory factor for the gendered patterns in sexual obligation's linkage to stress. These results highlight the importance of understanding gendered sexuality among aging older adults within the context of their relationship.Clinical Implications: Older adults' feelings of sexual obligation can manifest in their daily stress experience. Clinicians seeking to lower older adults', in particular older men's, stress levels should address the context of their sexual life and if they feel obligated to have sex, along with the positive and negative aspects of their relationship, as these could elevate their stress levels over time.

International differences in interspousal health correlations

Using objective measures of lung function, we document strong positive associations in health within couples in all European countries but large and significant differences in this correlation within broad European regions, with Southern Europe having by far stronger correlations than elsewhere. We analyze potential explanations for such differences, investigating the role of measures capturing current and past health behaviors, early life circumstances of each spouse, and measures capturing assortative mating in multiple dimensions. We show that marital sorting patterns by dimensions of early life health and socioeconomic position, as well as by geographical subregion within countries, are key to understanding the empirical patterns observed.

Dyadic Loneliness and Changes to HbA1c Among Older US Couples: The Role of Marital Support as Stress Buffer

Objectives: Both experiencing loneliness and having a lonely partner can be psychosocial stressors, with implications for health. Yet, marital support may buffer against the cardiometabolic effects of loneliness. This study examines (1) whether own and/or partner's loneliness predict changes in HbA1c over 4 years and (2) whether marital support moderates these effects. Methods: Actor-partner interdependence models analyzed data from 1,854 older couples who provided psychosocial and biomarker data at two timepoints (2008/2012 or 2010/2014) of the Health and Retirement Study. Results: Neither partner's loneliness predicted changes in HbA1c overall. However, significant interactions indicated that both own baseline loneliness and partner's baseline loneliness predicted significant increases to HbA1c over 4 years among those who reported below-average marital support. Discussion: Both the experience of loneliness and loneliness of a dyadic partner may have longitudinal consequences for cardiometabolic health. However, these effects are contingent upon perceived quality of the marriage, specifically marital support.

The Healing Hearts Together Randomized Controlled Trial and the COVID-19 Pandemic: A Tutorial for Transitioning From an In-Person to a Web-Based Intervention

Supportive couple relationships are associated with reduced risk of chronic illness development, such as cardiovascular disease, as well as improved secondary prevention. Healing Hearts Together (HHT) is an 8-week couples-based intervention designed to improve relationship quality, mental health, quality of life, and cardiovascular health among couples in which one partner has experienced a cardiac event. A randomized controlled trial began in October 2019 to test the efficacy of the in-person, group-based HHT program as compared to usual care. In March of 2020, all recruitment, assessments, and interventions halted due to the COVID-19 pandemic. Guided by optimal virtual care principles, as well as by Hom and colleagues’ four-stage framework—consultation, adaptation, pilot-testing, and test launch—this paper is a tutorial for the step-by-step transition planning and implementation of a clinical research intervention from an in-person to a web-based format, using the HHT program as an example. Clinical and research considerations are reviewed, including (1) privacy, (2) therapeutic aspects of the intervention, (3) group cohesion, (4) research ethics, (5) participant recruitment, (6) assessment measures, (7) data collection, and (8) data analyses. This tutorial can assist clinical researchers in transitioning their research programs to a web-based format during the pandemic and beyond.

A National Longitudinal Study of Partnered Sex, Relationship Quality, and Mental Health Among Older Adults

OBJECTIVES

We worked from a life course perspective to examine the relationship between partnered sex and older adults' trajectories of mental health as well as the potential mediating role of relationship quality in this association.

METHOD

We analyzed nationally representative data from three waves of the National Social Life, Health, and Aging Project (2005/2006 to 2015/2016). The sample included 1,911 married and cohabiting respondents aged 57 to 85 at the baseline survey. We examined four factors related to partnered sex: being sexually active, sexual frequency, feeling okay with sexual frequency, and sexual quality. Mental health was measured by self-rated poor mental health, unhappiness, and psychological distress. The relationship quality measures considered both relationship support and relationship strain.

RESULTS

Results from mixed-effects models suggest that being sexually active, having sex more frequently, feeling okay with sexual frequency, and reporting better sexual quality were all related to better mental health outcomes. Relationship quality partially explained the effects of sex on mental health.

DISCUSSION

This study highlights the importance of sex for mental health and relationship quality among older adults. The findings have implications for health policy and programs that seek to promote healthy aging.

Social Relationships and Loneliness in Late Adulthood: Disparities by Sexual Orientation

OBJECTIVE

This is the first national study to examine disparities in loneliness and social relationships by sexual orientation in late adulthood in the United States.

BACKGROUND

Prior studies have shown that lesbian, gay, and bisexual (LGB) individuals often struggle with social relationships across the life course, likely because of stigma related to sexual orientation. However, little is known about whether loneliness is more prevalent among LGB people than among other groups in late adulthood, and if so, which relationships contribute to the loneliness gap.

METHOD

We analyzed data from a nationally representative sample of older adults from the 2015-2016 National Social Life, Health, and Aging Project (N = 3,567) to examine the disparity in loneliness by sexual orientation and identify links between this disparity and multiple dimensions of social relationships, including partner, family, friend, and community relationships.

RESULTS

Older LGB adults were significantly lonelier than their heterosexual counterparts, primarily due to a lower likelihood of having a partner and, to a lesser extent, lower levels of family support and greater friend strain. While they were also disadvantaged in the size of close family and frequency of community participation, these factors were less relevant to their loneliness. Overall, the conventionally defined inner layers of relationships (partnership and family) contributed more to the loneliness disparity than the outer layers of relationships (friends and community).

CONCLUSION

These findings suggest that strengthening the partnerships and family relationships of sexual minorities is essential to reducing the loneliness gap.

The Influence of Family and Friend Confidants on Marital Quality in Older Couples

OBJECTIVES

Relationships with confidants play an important role in older adults' health and well-being. Particularly, family and friend confidants could significantly support or interfere with older adults' marital relationships. This study used a dyadic approach to examine the influence of the structural features of both spouses' family and friend confidant networks on older couples' marital quality over 5 years.

METHODS

Analyses used dyadic data from Wave 2 (2010-2011) and Wave 3 (2015-2016) interviews of the National Social Life, Health, and Aging Project (NSHAP), a nationally representative sample of community-dwelling older adults. Longitudinal actor-partner interdependence models were used to examine the influence of spouses' family and friend confidant networks on couples' marital quality.

RESULTS

Having a larger friend confidant network or closer connections with friend confidants predicted greater marital quality for wives and husbands 5 years later. Larger family confidant networks of both spouses predicted greater marital quality for wives over time. However, husbands reported worse marital quality over time if wives reported having closer connections with their own family confidants at baseline.

DISCUSSION

This study demonstrates the importance of family and friend confidant networks for older couples' marital quality and highlights the benefits of having a larger or closer friend confidant network. Future research should examine mechanisms that account for the effects of spouses' family and friend confidant networks on older couples' marital quality.

Marital Quality and Salivary Telomere Length Among Older Men and Women in the United States

Objective: The link between marital quality and cellular aging remains underexplored. This study examined how both positive and negative marital quality were associated with salivary telomere length among partnered adults in the United States over the age of 50°years. Methods: Data were from the 2008 Health and Retirement Study (N = 3203). Ordinary least squares regression was used to estimate the link between marital quality and telomere length. Results: While neither positive nor negative marital quality was significantly associated with telomere length among older women, positive and negative marital quality had an interacting effect on telomere length among men. Specifically, when negative marital quality was low, higher positive marital quality was associated with shorter telomere length, whereas when negative marital quality was high, higher positive marital quality was associated with longer telomere length. Discussion: The findings speak to the complex nature of intimate partnerships and the implications of these partnerships for cellular aging processes.

Associations between living alone, depression, and falls among community-dwelling older adults in the US

Social isolation is closely linked to depression and falls in late life and are common among seniors. Although the literature has highlighted age-related variations in these three geriatric conditions, evidence on heterogeneities across older adult age categories is lacking. To address this gap, we present cross-sectional analyses using indicators of social isolation, depression, and falls of older adults constructed from the most recent Behavioral Risk Factor Surveillance System (BRFSS) data. An age-based understanding is critical to improve health interventions since health changes occur at a faster rate among seniors than in any other population subgroup. We included all adults 60 years and older (n = 113,233) in the 2018 BRFSS landline dataset and used the status of living alone, depressive disorder diagnosis, and fall incidences reported by these seniors to respectively create the social isolation, depression, and fall indicators. We conducted multivariable logistic regressions to compare findings on these indicators across the three age categories of 60-69, 70-79, and 80 and above after adjusting for a common set of covariates. Results indicate that the likelihood of seniors living alone and reporting depression is the highest among those 80 years and above. Conversely, the odds of depressed seniors reporting falls is the greatest among the 60-69 year olds. Accordingly, we highlight key implications for targeted health promotion and care delivery to seniors.

Marital Quality and Well-Being Among Older Adults: A Typology of Supportive, Aversive, Indifferent, and Ambivalent Marriages

A large body of work has linked marital quality to the health and well-being of older adults, but there is a lack of agreement on how to best measure dimensions of marital quality. Drawing on a stress-process life course perspective, we construct a typology of marriage type that captures the synergistic relationship between positive and negative marital qualities and health. Using data from Wave 1 (2005/2006) and Wave 2 (2010/2011) of the NSHAP survey from the United States, we examine the association between supportive, aversive, ambivalent, and indifferent marriages for older adults that remained married over the study period on multiple indicators of well-being (depression, happiness, and self-rated health; N = 769 males and 461 females). Results suggest that older adults in aversive marriages reported lower happiness (men and women) and physical health (men). There was less evidence that those in ambivalent and indifferent marriages reported worse well-being.

Relationship Quality Among Older Cohabitors: A Comparison to Remarrieds

OBJECTIVES

Later life marital patterns have undergone shifts over the past few decades, including a rapid growth of cohabiting unions. Despite the increase in older adult cohabitation, research on this population has been slow to keep up. Intimate relationships are linked to well-being and relationship quality is especially important because high-quality relationships offer a number of benefits for well-being, whereas poor-quality relationships often are detrimental. This study compares cohabiting and remarried individuals on two measures of relationship quality.

METHOD

Using data from the 2010 and 2012 Health and Retirement Study, I investigate the positive and negative relationship quality of cohabitors relative to their remarried counterparts and whether the association of union type and relationship quality varies by race.

RESULTS

Across both positive and negative relationship quality, I found few differences between cohabiting and remarried individuals. Black cohabitors report higher positive relationship quality than remarrieds, whereas White cohabitors and remarrieds do not differ.

DISCUSSION

These findings suggest that cohabiting unions and remarriages are comparable among White older adults, but that Black cohabitors may gain more in terms of positive relationship quality than their remarried counterparts.

Marital Status and Dementia: Evidence from the Health and Retirement Study

OBJECTIVES

We provide one of the first population-based studies of variation in dementia by marital status in the United States.

METHOD

We analyzed data from the Health and Retirement Study (2000-2014). The sample included 15,379 respondents (6,650 men and 8,729 women) aged 52 years and older in 2000 who showed no evidence of dementia at the baseline survey. Dementia was assessed using either the modified version of the Telephone Interview for Cognitive Status (TICS) or the proxy's assessment. Discrete-time hazard regression models were estimated to predict odds of dementia.

RESULTS

All unmarried groups, including the cohabiting, divorced/separated, widowed, and never married, had significantly higher odds of developing dementia over the study period than their married counterparts; economic resources and, to a lesser degree, health-related factors accounted for only part of the marital status variation in dementia. For divorced/separated and widowed respondents, the differences in the odds of dementia relative to married respondents were greater among men than among women.

DISCUSSION

These findings will be helpful for health policy makers and practitioners who seek to better identify vulnerable subpopulations and to design effective intervention strategies to reduce dementia risk.

Romantic relationship distress, gender, socioeconomic status, and inflammation: A preregistered report

Poor quality romantic relationships increase risk for health problems; elevated systemic inflammation is one promising underlying mechanism. This registered report utilized data from 3 publicly available datasets with large sample sizes (Add Health, MIDUS, NSHAP) to test this possibility. An internal meta-analysis across all 3 studies determined that romantic relationship distress was unrelated to inflammation (assessed via C-Reactive Protein levels). In addition, this link was not moderated by gender, socioeconomic status (SES), or the combination of gender and SES.

What Can Buffer the Impact of Social Support on Chinese Older Adults' Life Satisfaction?

This study aims to test the moderating effects of home health care, home-help service, and older adults' attitudes toward aging on the relationship between social support and life satisfaction among Chinese older adults. The study used a sample of 5,578 Chinese home-dwelling older adults. Multiple linear regression analyses were performed to test the hypothesized effects along with gender and Hukou type differences. The results show that home health care significantly buffers the impact of social support on life satisfaction, and this buffering effect remains same across gender groups and Hukou groups. The findings of the study provide unique and contemporary theoretical and practical implications.

Perceived Health and Life Satisfaction of Elderly People: Testing the Moderating Effects of Social Support, Attitudes Toward Aging, and Senior Privilege

As health declines with age, it is critical to explore moderators that could buffer the impact of declining health on life satisfaction of elderly people. This study aims to test the moderating effects of social support, attitudes toward aging, and senior privilege on the relationship between perceived health and life satisfaction among elderly people. The study used a sample of 5809 Chinese elderly people. Multiple regression analyses were performed to test the moderating effects of the study variables along with gender difference. The results show that social support and attitudes toward aging do not moderate the relationship between perceived health and life satisfaction; senior privilege however, amplifies the impact of perceived health on life satisfaction for female elderly people. The findings recommend personalized provision of senior privilege based on health status and types of diseases, rather than only based on age; and suggest tailored female-oriented social services such as psychological counseling and humanistic care.

The Persian version of the revised dyadic adjustment scale (RDAS): a validation study in infertile patients

Background

Infertility can have a powerful impact on marital quality. The Revised Dyadic Adjustment Scale (RDAS) is a widely used measure of marital quality. This scale has not been validated in infertile patients. Therefore, this study aimed to evaluate the reliability and validity of the RDAS in a sample of infertile patients.

Methods

The sample of this methodological study consisted of 254 infertile patients referring to a referral infertility clinic in Tehran, Iran. A battery of questionnaires was administered to the participants, including a demographic/fertility questionnaire, the RDAS, the Relationship Assessment Scale (RAS), the Kansas Marital Satisfaction Scale (KMSS), the Couples Satisfaction Index- 4 Item (CSI-4), the Hospital Anxiety and Depression Scale (HADS), and the Perceived Stress Scale-4 Item (PSS-4). Internal consistency of the scale was assessed with Cronbach’s alpha, construct validity was investigated using confirmatory factor analysis (CFA), and convergent validity was examined by correlating the RDAS with RAS, KMSS, CSI-4, HADS, and PSS-4 instruments.

Results

The mean total RDAS score was 49.26 ± 9.34, and 100 patients (39.4%) had marital distress based on the cut-off value of < 48. The second-order three-factor model of the RDAS exhibited an excellent fit to the data, as indicated by χ²/df = 2.26; CFI = 0.96; GFI = 0.91; NFI = 0.93; IFI = 0.96; RMSEA = 0.071 and SRMR = 0.050. The RDAS and its subscales revealed satisfactory internal consistency that ranged from 0.664 to 0.847. Convergent validity was confirmed by strong correlations between RDAS scores and scores on the RAS, KMSS, and CSI-4. These correlations also tended to be larger than correlations with measures of HADS-anxiety, HADS-depression, and PSS-4. Among demographic/fertility variables, only infertility duration was found to be correlated to the RDAS.

Conclusion

The RDAS is a reliable and valid inventory for measuring marital quality in infertile patients. Further validation studies are needed to generalize the underlying structure of the scale in various populations.

Prevalência de hipertensão arterial em adultos no município de São Paulo e fatores associados

RESUMO: Objetivo: Analisar o comportamento da prevalência de hipertensão arterial no município de São Paulo e seus fatores associados. Métodos: O presente trabalho utilizou os dados do Inquérito de Saúde no Município de São Paulo (ISA Capital), estudo transversal de base populacional executado no município de São Paulo. Foram utilizados dados de 1.667 e de 3.184 indivíduos em 2003 e 2015, respectivamente, com idade de 20 anos e mais. Fizeram-se análises descritivas das prevalências de hipertensão arterial com respectivos intervalos de 95% de confiança. Análises simples e múltiplas foram realizadas para analisar possíveis associações com as variáveis socioeconômicas, demográficas e de estilo de vida por meio de regressão de Poisson. Resultados: A prevalência de hipertensão arterial passou de 17,2% em 2003 para 23,2% em 2015. Os fatores associados à hipertensão foram: sexo feminino; idade (60 anos e mais); situação conjugal (casados, separados e viúvos); ter religião; baixa escolaridade; ter nascido no estado de São Paulo (exceto capital); estado nutricional (baixo peso, sobrepeso e obesidade); e ex-fumantes. Conclusão: A prevalência de hipertensão autorreferida aumentou significativamente no período estudado em São Paulo. Considerando o impacto dessa doença na sociedade, conhecendo sua atual prevalência e identificando seus principais fatores associados, evidencia-se a necessidade de intensificar atividades que contribuam para a prevenção desse agravo, atenuando os danos aos indivíduos e gastos públicos.

Chronic Stress and Negative Marital Quality Among Older Couples: Associations With Waist Circumference

Objective

More than a third of the U.S. population of older adults is obese. The present study tests the Dyadic Biopsychosocial Model of Marriage and Health, which hypothesizes that, among married couples, individual and partner chronic stress predicts increased waist circumference and these links are exacerbated in negative quality marriages.

Method

Participants were from the nationally representative longitudinal Health and Retirement Study (HRS). A total of 2,042 married individuals (in 1,098 married couples) completed psychosocial and waist circumference assessments in 2006 and 2010. Analyses examined whether negative marital quality and chronic stress in Wave 1 (2006) were associated with changes in waist circumference over time.

Results

Actor-partner interdependence models revealed that greater partner stress, rather than individuals' own reports of stress, was associated with increased waist circumference over time. Higher perceived negative marital quality among husbands and lower negative marital quality among wives exacerbated the positive link between partner stress and waist circumference.

Discussion

Consistent with the Dyadic Biopsychosocial Model of Marriage and Health, partner stress has direct associations with waist circumference among couples and this link is moderated by negative marital quality. Thus, dyadic perceptions of stress and negative marital quality are important to consider for understanding marriage and obesity.

Marital status and cognitive impairment in the United States: evidence from the National Health and Aging Trends Study

PURPOSE

We provide population-based longitudinal evidence of marital status differences in the risk of cognitive impairment and dementia in the United States.

METHODS

Data were from the longitudinal National Health and Aging Trends Study, 2011-2018. The sample included 7508 respondents aged 65 years and older who contributed 25,897 person-year records. We estimated discrete-time hazard models to predict the risk of dementia and cognitive impairment, not dementia (CIND), as well as impairment in three major cognitive domains: memory, orientation, and executive function.

RESULTS

Relative to their married counterparts, divorced and widowed elders had higher odds of dementia and CIND, as well as higher odds of impairment in each of the cognitive domains. Never-married elders had higher odds of impairment in memory and orientation than their married counterparts but did not differ significantly in the odds of impaired executive function, dementia, or CIND. Cohabiting elders did not differ significantly from married respondents on any measure of cognitive impairment. We found no gender differences in the associations between marital status and the measures of cognitive impairment.

CONCLUSIONS

Marital status is a potentially important but overlooked social risk/protective factor for cognitive impairment. Divorced and widowed older adults are particularly vulnerable to cognitive impairment.

The Quality of Marriage Index (QMI): a validation study in infertile patients

OBJECTIVE

Infertility can have a considerable effect on a person's marital satisfaction. The Quality of Marriage Index (QMI) is a self-report inventory to measure global perceptions of marital satisfaction. The current study examined the reliability and validity of the Persian language version of QMI in a sample of infertile patients.

RESULTS

The mean QMI total score was 36.54 ± 6.87. The internal consistency of the scale was good, with a Cronbach's alpha of 0.922. All inter-item correlations and item-total correlations were also in acceptable range. The confirmatory factor analysis results provided evidence for unidimensionality of the scale (χ²/df = 3.10; GFI = 0.97; CFI = 0.99; NFI = 0.99; RMSEA = 0.091 and SRMR = 0.020). The convergent validity of the QMI was demonstrated via significant correlations with measures of the Relationship Assessment Scale, Kansas Marital Satisfaction Scale, and Couples Satisfaction Index-4 Item. These correlations also tended to be larger than correlations with measures of Hospital Anxiety and Depression Scale and Perceived Stress Scale-4 Item. Among demographic/fertility variables, only infertility duration was negatively correlated to QMI scores. In sum, the QMI is a reliable and valid brief inventory for measuring overall marital satisfaction in infertile patients. Trial registration This was a cross-sectional study (NOT clinical trial); thus, the trail registration number is not required for the present study.

A descriptive pilot study of structural and functional social network ties among women in the women's health initiative (WHI) study

Few studies examine the network structure and function of older women's health discussion networks. We sought to assess the feasibility and acceptability of collecting social network data via telephone from 72 women from the Women's Health Initiative study and to describe structural and functional characteristics. Women were socially connected and had dense networks. Women were emotionally close to network members, but their networks were not used to facilitate communication with health-care providers. One-third of network members was not influential on health-related decision-making. Collecting social network data via telephone is feasible and an acceptable, though un-preferred, mode of data collection.

Chronic Disease Burden, Sexual Frequency, and Sexual Dysfunction in Partnered Older Adults

This research evaluates the relationship between chronic disease burden and partnered sexuality of older adults by using data from the National Social Life, Health, and Aging Project. Ordinary least squares and logistic regressions identify how chronic disease burden is associated with sexual frequency and sexual dysfunction for men (N = 893) and women (N = 641). Results indicate that an increasing chronic disease burden is negatively associated with men's sexual frequency, while a greater burden of chronic disease is related to a greater risk of lubrication problems for women and orgasm problems for men. The findings reveal gender differences in how disease is linked to older adults' sexual lives.

Gender/Sex as a Social Determinant of Cardiovascular Risk

The social gradient for cardiovascular disease (CVD) onset and outcomes is well established. The American Heart Association's Social Determinants of Risk and Outcomes of Cardiovascular Disease Scientific Statement advocates looking beyond breakthroughs in biological science toward a social determinants approach that focuses on socioeconomic position, race and ethnicity, social support, culture and access to medical care, and residential environments to curb the burden of CVD going forward. Indeed, the benefits of this approach are likely to be far reaching, enhancing the positive effects of advances in CVD related to prevention and treatment while reducing health inequities that contribute to CVD onset and outcomes. It is disappointing that the role of gender has been largely neglected despite being a critical determinant of cardiovascular health. It is clear that trajectories and outcomes of CVD differ by biological sex, yet the tendency for sex and gender to be conflated has contributed to the idea that both are constant or fixed with little room for intervention. Rather, as distinct from biological sex, gender is socially produced. Overlaid on biological sex, gender is a broad term that shapes and interacts with one's cognition to guide norms, roles, behaviors, and social relations. It is a fluid construct that varies across time, place, and life stage. Gender can interact with biological sex and, indeed, other social determinants, such as ethnicity and socioeconomic position, to shape cardiovascular health from conception, through early life when health behaviors and risk factors are shaped, into adolescence and adulthood. This article will illustrate how gender shapes the early adoption of health behaviors in childhood, adolescence, and young adulthood by focusing on physical activity, drinking, and smoking behaviors (including the influence of role modeling). We will also discuss the role of gender in psychosocial stress with a focus on trauma from life events (childhood assault and intimate partner violence) and work, home, and financial stresses. We conclude by exploring potential biological pathways, with a focus on autonomic functioning, which may underpin gender as a social determinant of cardiovascular health. Finally, we discuss implications for cardiovascular treatment and awareness campaigns and consider whether gender equality strategies could reduce the burden of CVD for men and women at the population level.

Assessing spousal support and health in an aging population: support and strain amidst changing social dynamics

This study examined the role of relationship quality on physical and psychological health among older adults. It included 2,298 adults aged 50 and older who participated in the Midlife in the US national longitudinal study of health and well-being. We assessed the effect of spousal support and strain on psychological and physical health, controlling for age, education, income, depression levels and prior health. Results indicated that spousal support and strain affected psychological health but not physical health. Despite prior research showing an association between marital quality and physical health, this study did not support the conceptualization that relationship quality measured by spousal support or strain has a direct effect on long-term health in this sample of older adults. This study does not preclude the presence of a mediated or moderated association between relationship quality and physical health. Higher levels of spousal support are associated with positive psychological health among adults over age 50 while spousal strain is associated with negative psychological health. This study supports the premise that relationship quality has an ongoing impact on the psychological health of mature adults, bolstering arguments to include psychological health screening and couples relationship education among health services provided to older adults.

Relationship quality and functional limitations among older adults with cardiovascular disease in the United States of America

Substantial research shows that cardiovascular disease is a major cause of disability in the United States of America (USA) and worldwide. Despite the well-documented significance of intimate partnerships for cardiovascular health and disease management, how relationship quality contributes to the functional health of older adults diagnosed with cardiovascular disease is much less understood than mental health and mortality risk. Informed by the disablement process model and the lifecourse perspective, this study examines the association between relationship quality and functional limitations among partnered older adults aged 50 years and older diagnosed with cardiovascular disease in the USA. Data are from the Health and Retirement Study, 2006–2012 (N = 1,355). Multi-level linear regression analyses show that baseline negative relationship quality is significantly associated with increased functional limitations over the two- and four-year follow-ups. Additionally, the link between negative relationship quality and functional limitations is stronger among older adults with lower household income over a two-year span, compared to their higher-income counterparts, suggesting that these older adults are doubly disadvantaged by higher relationship strains and limited economic resources. Our findings demonstrate the significance of relationship quality for the functional health of older adults with cardiovascular disease and shed light on the importance of marriage/partnerships as an important social context for a critical stage in the disablement process (i.e. functional limitations).

Social interactions and physical symptoms in daily life: quality matters for older adults, quantity matters for younger adults

Objective: The present study examined how the different attributes of daily social interactions (quality and quantity) were associated with physical health, and how these associations vary with age. Method: Using an ecological momentary assessment approach, participants from an adulthood lifespan sample (n = 172; aged 20-79 years) reported their social interactions five times daily, and physical symptoms and symptom severity at the end of each day, for one week. Main outcome measures: Number of physical symptoms and physical symptom severity. Results: There was a within-person main effect of the quality (positivity), but not the quantity (frequency), of social interactions on the number of reported physical symptoms and their severity. Moderation analyses further revealed that the quality of daily social interactions predicted fewer physical symptoms for older adults, but not for younger adults; in contrast, the frequency of social interactions predicted less severe physical symptoms for younger adults, but not for older adults. Finally, the reported severity of physical symptoms predicted less frequent but more positive social interactions the next day. Conclusions: Our findings point to the bidirectional associations between social interactions and health and highlight the importance of considering individuals' developmental context in future research and interventions.

Social Integration and Quality of Social Relationships as Protective Factors for Inflammation in a Nationally Representative Sample of Black Women

Social integration and supportive relationships protect against cardiovascular disease (CVD). However, prior studies have examined heterogeneous samples which may obscure unique relationships within groups. We investigate the association between social relationships and inflammation-a known CVD risk factor-in Black women, a population with higher rates of CVD and CVD mortality. Secondary data from wave 4 of the National Longitudinal Study of Adolescent to Adult Health (Add Health) were analyzed. The sample was comprised of 1829 Black women aged 24-34 years. Social integration was a z-score standardized measure of four items (marital/cohabitation status, church attendance, volunteerism, close friendships). Data on the quality of three relationship types was available: perceived happiness with a romantic relationship and perceived closeness to mother and father figure. Inflammation was measured via high-sensitivity C-reactive protein (hs-CRP) in which levels were categorized based on clinical cut-points for risk of CVD (< 1 mg/L = low risk-reference, 1-3 mg/L = moderate risk, > 3-10 mg/L = high risk, > 10 mg/L = very high risk). Multivariable logistic regression was conducted accounting for the complex survey design and wave 4 control measures (e.g., body mass index, smoking, medications, acute illness, overall health, sociodemographic factors). No significant associations were found between level of social integration and hs-CRP levels. With respect to relationship quality, women who reported they were very happy with their romantic relationship were less likely than those who were only fairly happy or unhappy to have hs-CRP levels in the moderate- (AOR = 0.36, 95% CI = 0.17, 0.75), high (AOR = 0.20, 95% CI = 0.08, 0.49), or very high CVD-risk category (AOR = 0.36, 95% CI = 0.16, 0.80). Women who reported they were somewhat/quite/very close to their mother figure (AOR = 0.48, 95% CI = 0.25, 0.92) and those who reported having no mother figure (AOR = 0.25, 95% CI = 0.08, 0.77) were less likely than women reporting being not very close/not close at all with their mother figure to have hs-CRP levels in the moderate- vs. low-risk category. No statistically significant associations were found between father-figure relationship and hs-CRP CVD risk category. In summary, social integration and the quality of specific social relationships were significantly associated with inflammation in young adult Black women. Thus, interventions designed to enhance social connectedness and positive social relationships among Black women may have the potential to be protective for CVD risk. Further researches with the longitudinal social relationship and inflammatory measures are needed to better understand how changes in social relationships may influence CVD risk over the life course.

A National Dyadic Study of Oral Sex, Relationship Quality, and Well-Being among Older Couples

Objectives

We examine how giving versus receiving oral sex, 2 processes that are linked to relationship quality, are associated with older men's and women's well-being.

Method

We analyzed 884 heterosexual couples from the National Social Life, Health, and Aging Project (2010-2011). We estimate Actor-Partner Interdependence Models using the SEM approach to assess three well-being outcomes: general happiness, psychological distress, and self-reported mental health.

Results

Older adults with better relationship quality gave oral sex to their partner more often than those with worse relationship quality; this association was stronger for men than for women. While receiving oral sex was positively related to both men's, and women's perceptions of relationship quality, women's relationship quality was more strongly linked to their partners' well-being than men's. Correspondingly, men's giving of oral sex (and thus their female partner's receiving of oral sex) was positively related to their own well-being through increasing their female partner's perceived relationship quality.

Discussion

Given the high prevalence of sexual dysfunctions among older adults, oral sex may play an important but overlooked role in maintaining an active sexual life, a high-quality relationship, and psychological vibrancy in late life.

Social Role-Related Stress and Social Role-Related Reward as Related to Subsequent Subclinical Cardiovascular Disease in a Longitudinal Study of Midlife Women: The Study of Women's Health Across the Nation

OBJECTIVE

The purpose of this study was to determine if midlife social role quality, defined by the stress and rewards associated with four social roles, is related to later-life subclinical cardiovascular disease (SCVD) in a cohort of women transitioning through menopause.

METHODS

The Study of Women's Health Across the Nation (SWAN) is a longitudinal cohort study of midlife women. Stress and reward from four social roles (spouse, parent, employee, caregiver) were assessed at seven early visits. Later-life SCVD was assessed via carotid ultrasound and brachial-ankle pulse wave velocity at two later visits. We tested whether ever reporting an "extremely" or "quite a bit" stressful role was related to SCVD. We also tested whether cumulative stress and reward, as well as baseline and change in stress and reward were related to SCVD, adjusting for demographics and cardiovascular risk factors.

RESULTS

Among 1602 women, reporting a stressful role during midlife (between ages 47 and 52 years) was associated with later-life (age 61 years) carotid intima-media thickness, which was 21 μm thicker than never reporting a stressful role. No significant relationships between stressful roles and other SCVD measures were identified. Cumulative and baseline change models of stress and reward were not related to SCVD.

CONCLUSION

A stressful social role in midlife was associated with greater atherosclerotic burden in later-life in a cohort of women transitioning through menopause. Social role rewards were unrelated to better later-life SCVD. These findings extend the knowledge of stress and cardiovascular disease in women by using measures of stress and reward for multiple social roles over the years of midlife.

Marriage Dissatisfaction and the Risk of Sudden Cardiac Death Among Men

Conflicts in marriage have been associated with potential risk of cardiovascular disease; however, there is lack of prospective evidence on the association between marriage satisfaction and sudden cardiac death (SCD). We aimed to assess the association between perceived level of marriage satisfaction and risk of SCD. This study employed the Kuopio Ischemic Heart Disease study, an ongoing prospective population-based study in Finland. Perceived level of marriage satisfaction was assessed in 2,262 men using a well-structured self-administered questionnaire. Multivariable adjusted Cox regression models were used to estimate hazard ratios (95% confidence interval [CI]) for SCD. During a median follow-up period of 25.9 years, 239 SCDs were recorded. The mean age of participants was 53 (SD 5.2) years. On adjustment for several conventional cardiovascular risk factors, hazard ratio (95% CI) of SCD was 1.90 (CI 1.09 to 3.32; p = 0.02) for men who were dissatisfied with their marriage, compared with men who were satisfied with their marriage. The association remained consistent on further adjustment for preexisting coronary heart disease, socioeconomic status, and years of education 1.86 (CI 1.07 to 3.25; p = 0.03). In conclusion, dissatisfied marriage is associated with an increased risk of SCD among middle-aged Caucasian men, independent of conventional cardiovascular risk factors.

Something Old, Something New: When Gender Matters in the Relationship between Social Support and Health

This paper investigates how social support differentially benefits self-rated health among men and women hospitalized with heart disease. Using cross-sectional data about patients admitted to a university hospital, we examine the extent to which gender moderates effects for the frequency of contact with family, friends, and neighbors on health and whether these effects differ between those with new versus established diagnoses. We find that gender differentiates the effect of nonmarital family contact on health but only when heart disease is newly diagnosed. When newly diagnosed, more frequent contact with family is associated with better self-rated health for women but not men. Men and women with preexisting diagnoses benefit equally from more frequent contact with family.

Family status and later-life depression among older adults in urban Latin America and the Caribbean

Rapid fertility declines in Latin American and Caribbean countries since the 1960s have contributed to smaller family sizes among the current cohorts of older adults. This may have mental health implications in these societies as the family unit is highly valued as a source of social support. Utilising data from the 2000 Survey of Health, Well-being and Aging in Latin America and the Caribbean (SABE), this study examines the association between parental status, marital status and the likelihood of experiencing depressive symptoms among adults 60 years and older in seven cities within Latin America and the Caribbean (N = 9,756): Buenos Aires, Bridgetown, São Paulo, Santiago, Havana, Mexico City and Montevideo. Results from multivariate logistic regressions indicate that parental status is not significantly associated with depressive symptoms. Nonetheless, unmarried older adults, both those living alone and those living with others, are more vulnerable to experiencing depressive symptoms than their married counterparts. Marriage is especially protective for older adults in Havana and Montevideo. Older adults’ perceived income adequacy significantly moderates the relationship between marital status and depressive symptoms. Other significant covariates, such as experiencing disability and comorbidity, showed positive associations with depressive symptoms. While families may still represent a critical component for the mental health of older adults, broader investments in health across the lifespan are needed to improve individual psychological wellbeing.

Women's spousal choices and a man's handshake: Evidence from a Norwegian study of cohort differences

Both high grip strength and being married independently relate to better functional capacity and health at older ages, but the combined effect of marital status and strength have not been investigated. Especially at older ages, declining strength can have adverse health and social consequences, where having a spouse could potentially help with everyday support and alleviate some of the negative effects of sarcopenia. We investigate how grip strength relates to being married among two cohorts of 59–71 year olds (born 1923-35 and 1936-48) in the Norwegian city of Tromsø, controlling for a broad set of health variables and sociodemographic characteristics. The baseline included N = 5009 participants of whom 649 died during follow-up. We find that for men, particularly among younger cohorts, the physically stronger are more likely to be married, but no relation is found for women. This is consistent with a hypothesis that women increasingly have selected male marital partners based on preferred individual traits, whereas men do not emphasize strength when selecting women. We find that both marital status and grip strength independently affect mortality, but there is no significant joint effect. However, the distribution of strength and marital status implies that more men than women and increasing shares of later born cohorts have a “double-burden” of low strength and a lack of support from a spouse.

When couples' hearts beat together: Synchrony in heart rate variability during conflict predicts heightened inflammation throughout the day

Hostile conflict in marriage can increase risks for disease and mortality. Physiological synchrony between partners-e.g., the linkage between their autonomic fluctuations-appears to capture engagement, or an inability to disengage from an exchange, and thus may amplify the health risks of noxious interactions such as marital conflict. Prior work has not examined the unique health correlates of this physiological signature. To test associations between couples' heart rate variability (HRV) synchrony during conflict and inflammation, 43 married couples engaged in a marital problem discussion while wearing heart monitors and provided four blood samples; they repeated this protocol at a second visit. When couples' moment-to-moment HRV changes tracked more closely together during conflict, they had higher levels of three inflammatory markers (i.e., IL-6, stimulated TNF-α, and sVCAM-1) across the day. Stronger HRV synchrony during conflict also predicted greater negative affect reactivity. Synchrony varied within couples, and was related to situational factors rather than global relationship traits. These data highlight partners' HRV linkage during conflict as a novel social-biological pathway to inflammation-related disease.

The Case for Insurance Reimbursement of Couple Therapy

A case is made for why it may now be in the best interest of insurance companies to reimburse for marital therapy to treat marital distress. Relevant literature is reviewed with a considerable focus on the reasons that insurance companies would benefit from reimbursing marital therapy - the high costs of marital distress, the growing link between marital distress and a host of related physical and mental health problems, as well as the availability of empirically supported treatments for marital distress. This is followed by a focus on the major reasons insurance companies cite for not reimbursing marital therapy, along with a discussion of advances in several growing bodies of research to address these concerns. Main arguments include the direct medical offset costs of couple and family therapy (including for high utilizers of health insurance), and the fact that insurance companies already find it cost effective to reimburse for prevention of other health and psychological problems. This is followed by implications for practitioners and researchers.

Drinking Patterns Among Older Couples: Longitudinal Associations With Negative Marital Quality

Objectives

Research with younger couples indicates that alcohol use has powerful effects on marital quality, but less work has examined the effects of drinking among older couples. This study examined whether dyadic patterns of drinking status among older couples are associated with negative marital quality over time.

Method

Married participants (N = 4864) from the Health and Retirement Study reported on alcohol consumption (whether they drink alcohol and average amount consumed per week) and negative marital quality (e.g., criticism and demands) across two waves (Wave 1 2006/2008 and Wave 2 2010/2012).

Results

Concordant drinking couples reported decreased negative marital quality over time, and these links were significantly greater among wives. Wives who reported drinking alcohol reported decreased negative marital quality over time when husbands also reported drinking and increased negative marital quality over time when husbands reported not drinking.

Discussion

The present findings stress the importance of considering the drinking status rather than the amount of alcohol consumed of both members of the couple when attempting to understand drinking and marital quality among older couples. These findings are particularly salient given the increased drinking among baby boomers and the importance of marital quality for health among older couples.

Marital status and outcomes after myocardial infarction: Observations from the Canadian Observational Antiplatelet Study (COAPT)

While divorced or living alone, patients with stable cardiovascular disease are at increased risk for adverse cardiovascular events. The importance of marital status following a myocardial infarction (MI) is less clear. We hypothesized that marital status may affect cardiovascular outcomes following MI. We analyzed outcomes among patients with MI who underwent percutaneous coronary intervention from the Canadian Observational Antiplatelet Study (COAPT). Marital status was categorized into 3 groups: married/common-law patients living together; never married; and divorced, separated, or widowed patients. Patients were followed for 15 months and our primary outcome was the occurrence of a major adverse cardiovascular event (MACE), defined as a composite of mortality, repeat acute MI, stroke, or urgent coronary revascularization. Multivariable logistic regression models were performed, with married/common-law patients living together considered the reference group. Among 2100 patients included in analyses, 1519 (72.3%) were married/common-law patients living together, 358 (17.1%) were separated/divorced/widowed, and 223 (10.6%) patients were never married. Dual antiplatelet therapy use after 15 months was similar across groups (75.4%, 77.8%, and 73.6%, respectively). The risk of MACE after 15 months was similar among married patients living together (12.7%; referent) compared with patients who were never married (13.9%; adjusted odds ratio: 1.09, 95% confidence interval: 0.58-2.07, P = 0.79) and patients separated/divorced/widowed (14.3%; adjusted odds ratio: 0.71, 95% confidence interval: 0.40-1.25, P = 0.23). Similarly, the risk of individual endpoints, including mortality, was similar across the 3 groups. Among patients stabilized following an MI, we found no association between marital status and 15-month outcomes.

Family Relationships and Well-Being

Family relationships are enduring and consequential for well-being across the life course. We discuss several types of family relationships—marital, intergenerational, and sibling ties—that have an important influence on well-being. We highlight the quality of family relationships as well as diversity of family relationships in explaining their impact on well-being across the adult life course. We discuss directions for future research, such as better understanding the complexities of these relationships with greater attention to diverse family structures, unexpected benefits of relationship strain, and unique intersections of social statuses.

Communal Coping and Adjustment to Chronic Illness: Theory Update and Evidence

We present a theory of communal coping that describes an optimal pathway to patient adjustment among couples in which one person faces a chronic illness. Communal coping consists of a shared illness appraisal (i.e., person perceives illness as a joint rather than individual problem) and collaboration with a partner to manage the illness. We present a model of the communal coping process that links patient and partner shared illness appraisals to collaboration and a set of supportive interactions that might be reframed as collaboration in the presence of shared illness appraisals. We then outline a model that identifies potential antecedents of communal coping and mechanisms that link communal coping to patient illness adjustment (i.e., enhanced psychological well-being, improved health behaviors, better physical health) and partner psychological well-being. We review the empirical evidence for this model and conclude by identifying several moderator variables, noting potential limitations, and outlining future research directions.

Changes in marital quality over 6 years and its association with cardiovascular disease risk factors in men: findings from the ALSPAC prospective cohort study

BACKGROUND

Marital relationship quality has been suggested to have independent effects on cardiovascular health outcomes. This study investigates the association between changes in marital relationship quality and cardiovascular disease (CVD) risk factors in men.

METHODS

We used data from The Avon Longitudinal Study of Parents and Children, a prospective birth cohort study (Bristol, UK). Our baseline sample was restricted to married study fathers with baseline relationship and covariate data (n=2496). We restricted final analysis (n=620) to those with complete outcome, exposure and covariate data, who were married and confirmed the study child's father at 6.4 years and 18.8 years after baseline. Relationship quality was measured at baseline and 6.4 years and operationalised as consistently good, improving, deteriorating or consistently poor relationship. We measured CVD risk factors of blood pressure, resting heart rate, body mass index, lipid profile and fasting glucose at 18.8 years after baseline.

RESULTS

Improving relationships were associated with lower levels of low-density lipoprotein (-0.25 mmol/L, 95% CI -0.46 to -0.03) and relative reduction of body mass index (-1.07 kg/m², 95% CI -1.73 to -0.42) compared with consistently good relationships, adjusting for confounders. Weaker associations were found between improving relationships and total cholesterol (-0.24 mmol/L, 95% CI -0.48 to 0.00) and diastolic blood pressure (-2.24 mm Hg, 95% CI -4.59 to +0.11). Deteriorating relationships were associated with worsening diastolic blood pressure (+2.74 mm Hg, 95% CI 0.50 to 4.98).

CONCLUSIONS

Improvement and deterioration of longitudinal relationship quality appears associated with respectively positive and negative associations with a range of CVD risk factors.

Marriage, Cohabitation, and Divorce in Later Life

Older adults are at the forefront of family change as a declining share experiences lifelong marriage and rates of cohabitation and divorce in later life continue to rise. The goal of this article is to review recent scholarship on marriage, cohabitation, and divorce among older adults and identify directions for future research. The varied family experiences characterizing the later life course demonstrate the importance of moving beyond marital status to capture additional dimensions of the marital biography, including transitions, timing, duration, and sequencing. Cohabitation operates as an alternative to marriage for older adults and is increasingly replacing remarriage following divorce or widowhood. The gray divorce rate has doubled in recent decades as older adults abandon marriage in favor of unmarried partnerships or singlehood. The retreat from marriage among older adults raises important questions about the ramifications of family change for health and well-being as well as access to caregivers given that spouses historically have been the primary source of care.

Prehypertension and its optimal indicator among adults in Hubei Province, Central China, 2013-2015

BACKGROUND

Hypertension accounts for 7% of the annual global disease burden, despite great efforts to counter this trend. Thus, interventions targeted at prehypertension might lead to a breakthrough for hypertension prevention. This study focused on the prevalence of prehypertension among adults in Central China and the best indicator of prehypertension, which would provide the basis for future interventions.

METHODS

This cross-sectional study was conducted using multistage stratified random sampling in seven counties in Hubei Province. Data from 30,634 survey respondents were analyzed using logistic regression and receiver operating characteristic (ROC) curve statistical tests, for the prevalence of prehypertension and the predictive ability of body mass index (BMI), waist-to-height ratio (WHtR), and waist circumference (WC) for prehypertension.

RESULTS

The prevalence of prehypertension in adults was 42.2%. The following factors contributed to the risk of prehypertension: male sex, elder age, divorce/separation, drinking, heavy labor intensity, and high BMI (p < 0.05). Being a farmer and exercise exhibited positive associations with prehypertension (p < 0.05). Compared with BMI and WHtR, WC had a higher predictive value for prehypertension (area under ROC curve, AUC = 0.630, 95% confidence interval: 0.623-0.637, p < 0.0001), especially for men. The optimal cutoffs of WC for prehypertension were 79.95 cm in men and 76.85 cm in women.

CONCLUSIONS

The prehypertension rate in adults was high in Central China. Significant factors related to hypertension were identified. More interventions targeting individuals with WC above the cutoff level are needed for timely awareness of prehypertension and early prevention of hypertension.
