Depressed mood but not fatigue mediate the relationship between physical activity and perceived stress in middle-aged women

Effects of mind-body exercise on perimenopausal and postmenopausal women: a systematic review and meta-analysis

IMPORTANCE

The increasing attention to the management of perimenopausal and postmenopausal women parallels the growth of the aging population. Although hormone therapy is commonly used to alleviate menopausal symptoms, it carries a potential risk of cancer. Recently, mind-body exercises have emerged as innovative approaches for improving menopausal symptoms and bone health. However, research findings have needed to be more consistent, highlighting the significance of this study's systematic review of mind-body exercise effects on perimenopausal and postmenopausal women.

OBJECTIVE

This study aims to evaluate the impact of mind-body exercises, including tai chi, yoga, Pilates, qigong, baduanjin, and mindfulness-based stress reduction, on bone mineral density, sleep quality, anxiety, depression, and fatigue among perimenopausal and postmenopausal women.

EVIDENCE REVIEW

Four electronic databases-PubMed, Embase, Cochrane Central Register of Controlled Trials, and Web of Science-were systematically searched from inception until July 2023. The search focused exclusively on randomized controlled trials to examine the impact of mind-body exercise interventions on perimenopausal and postmenopausal women. The methodological quality of the included studies was evaluated using the Cochrane Bias Risk Assessment tool.

FINDINGS

A total of 11 randomized controlled trials, comprising 1,005 participants, were included in the analysis. Traditional meta-analysis indicated that mind-body exercise significantly enhanced bone mineral density in perimenopausal and postmenopausal women compared with control groups, with a standardized mean difference (SMD) of 0.41 (95% CI, 0.17 to 0.66; P = 0.001, I2 = 7%). In addition, significant improvements were observed in sleep quality (SMD, -0.48; 95% CI, -0.78 to -0.17; P = 0.002, I2 = 76%), anxiety reduction (SMD, -0.80; 95% CI, -1.23 to -0.38; P = 0.0002, I2 = 84%), depressive mood (SMD, -0.80; 95% CI, -1.17 to -0.44; P < 0.0001, I2 = 79%), and fatigue (SMD, -0.67; 95% CI, -0.97 to -0.37; P < 0.0001, I2 = 0%).

CONCLUSIONS AND RELEVANCE

The findings of this meta-analysis demonstrate that mind-body exercise positively influences bone mineral density, sleep quality, anxiety, depression, and fatigue among perimenopausal and postmenopausal women.

Translation and validation of the Depression Anxiety Stress Scales for menopausal women in Indonesia

OBJECTIVE

This study evaluated the construct validity of the Depression Anxiety Stress Scales-21 (DASS-21) for menopausal women in Indonesia.

METHODS

This cross-sectional study included 236 women aged 45-60 years and assessed internal consistency using Cronbach's α. The study used convenience sampling. Test-retest reliability was measured twice on an extra 30 women at 1-week and 2-week intervals. Confirmatory factor analysis (CFA) was employed to investigate its structural model fit.

RESULTS

The intraclass correlation coefficient for the test-retest reliability ranged between 0.95 and 0.96. The overall Cronbach's α coefficient of the DASS-21 was 0.95. The CFA results indicated that the goodness-of-fit index was 0.85, comparative fit index was 0.95, root-mean-square error of approximation was 0.07, related fit index was 0.91 and normed fit index was 0.92.

CONCLUSIONS

This study's results indicated that the DASS-21 has satisfactory validity and reliability for detecting depression, anxiety and stress in menopausal women in Indonesia.

General and Central Obesity Are Associated With Increased Severity of the VMS and Sexual Symptoms of Menopause Among Chinese Women: A Longitudinal Study

BACKGROUND

Strong evidence has linked overweight and obesity to increased risks of cardiovascular disease and all-cause mortality in Chinese populations. Menopause is considered associated with increased obesity and central body fat distribution. However, the correlation between obesity and menopausal symptoms has not been well studied.

OBJECTIVE

To examine the associations between obesity or abdominal obesity and menopausal symptoms as women progressed from premenopausal to postmenopausal status.

DESIGN

This study included 430 midlife Chinese women who had experienced natural menopause and were followed up for 10 years. Physical examinations and questionnaires should be completed annually. The questionnaires include the Menopause-Specific Quality of Life questionnaire, the Hospital Anxiety and Depression Scale, and other physical and behavioral factors.

RESULTS

Among women who were not obese (n=345) or not abdominal obese (n=372) at baseline, 5.8% and 31.7% became obese or abdominal obese at the recent follow-up visit, respectively. Women at the recent follow-up visit had an increased body mass index (BMI) by 0.14%, and the waist-to-hip ratio (WHR) increased by 5.2% compared with the data at baseline. In multivariate analysis, more frequent hot flashes, moderate/severe bothered vasomotor symptoms (VMS), mild bothered sexual functioning, and less anxiety symptoms were significantly associated with obesity. Increasing age, moderate/severe bothered VMS, and less anxiety symptoms were independently associated with abdominal obesity. Multivariable analysis also showed that less education level is independently associated with both obesity and abdominal obesity.

CONCLUSION

Our findings suggest that the proportion of obesity and abdominal obesity increased gradually during menopause. The increase of abdominal obesity is more rapidly than obesity in middle-aged women. Both obesity and abdominal obesity are related with severe or frequent VMS and anxiety symptoms in Chinese women. Although the proportion of obese women in China is lower than in western countries, the problem of abdominal obesity and related complications cannot be ignored.

Psychological Climacteric Symptoms and Attitudes toward Menopause among Emirati Women

Menopause is an inevitable developmental event that women encounter at an age of 42–54 years. The drop of estrogen levels that accompanies cessation of menstruation is associated with multiple vasomotor, physical, neuropsychological, and sexual symptoms, which may hamper quality of life. This study aimed to examine the severity of psychological symptoms and their correlates among peri- and postmenopausal Emirati women (N = 60, mean age = 54.88 ± 6 years). Participants were interviewed using the Menopause-Specific Quality of Life (MENQOL) and attitudes toward menopause scale (ATMS). In four path analysis models, vasomotor symptoms, weight gain, and fatigue had significant direct effects on symptoms of anxiety, depression (only weight gain and fatigue), and psychological distress. Fatigue significantly mediated the effects of vasomotor symptoms and weight gain on symptoms of anxiety, depression (only vasomotor symptoms), psychological distress, and memory problems. These models explained 47.6%, 44.5%, 56.6%, and 29.1% of the variances in anxiety, depression, psychological distress, and memory problems, respectively. Participants with more severe menopausal symptoms expressed more negative attitudes toward menopause though regression analysis revealed that only vasomotor symptoms could significantly contribute to ATMS scores. In conclusion, psychological distress is widespread among menopausal women, and it is associated with vasomotor symptoms, fatigue, and change of body composition (obesity). Psychological symptoms, along with vasomotor symptoms, express a key link to negative attitudes toward menopause. Therefore, interventional strategies that target psychological distress may promote coping with midlife transition and improve mental health among menopausal women.

Recent Studies on Anti-Depressant Bioactive Substances in Selected Species from the Genera Hemerocallis and Gladiolus: A Systematic Review

Herbal therapy is a potential alternative applied to pharmacological alleviation of depression symptoms and treatment of this disorder, which is predicted by the World Health Organization (WHO) to be the most serious health problem worldwide over the next several years. It has been well documented that many herbs with psychotropic effects have far fewer side effects than a variety of pharmaceutical agents used by psychiatrists for the treatment of depression. This systematic review presents literature data on the antidepressant activity of representatives of the genera Hemerocallis (H. fulva and H. citrina Baroni, family Xanthorrhoeaceae) and Gladiolus (G. dalenii, family Iridaceae) and on biologically active compounds and their mechanisms of action to consider the application of herbal preparations supporting the treatment of depression.

Effects of Pilates training on sleep quality, anxiety, depression and fatigue in postmenopausal women: A randomized controlled trial

OBJECTIVES

To analyze the effects that a Pilates-based exercise program has on sleep quality, anxiety, depression and fatigue in community-dwelling Spanish postmenopausal women aged 60 and over.

STUDY DESIGN

A total of 110 women (69.15 ± 8.94 years) participated in this randomized controlled trial. They were randomly allocated to either a control (n = 55) or a Pilates (n = 55) group.

MAIN OUTCOME MEASURES

Sleep quality and self-perceived fatigue were assessed by the Pittsburgh Sleep Quality Index (PSQI) and the Fatigue Severity Scale, respectively. Anxiety and depression were evaluated using the Hospital Anxiety and Depression Scale (HADS).

RESULTS

Significant improvements were observed after Pilates training in all PSQI domains as well as in the PSQI total score, with small to medium-size effects, while significant between-group differences in post-intervention measures were observed only for sleep duration (d = 0.69) and sleep disturbances (d = 0.78). Moreover, intra- and inter-group statistical differences were observed for depression (d = 0.39 and d = 0.86, respectively) and for anxiety (d = 0.43 and d = 1.27 respectively). Finally, participants in the Pilates group experienced a decrease in self-perceived fatigue after the intervention period (d = 0.32).

CONCLUSIONS

For community-dwelling Spanish postmenopausal women aged 60 years and over, a twelve-week Pilates exercise intervention has beneficial effects on sleep quality, anxiety, depression and fatigue.

Illness perception and sense of well-being in breast cancer patients

PURPOSE

The objective of the study was to explore breast cancer patients' illness perception, its relationship to perceived sense of well-being, and the role of perceived social support.

METHODS

Women with diagnosed breast cancer were recruited from the two university hospitals in South Korea between January and April 2018. The questionnaires included the Illness Perception Questionnaire-Revised (IPQ-R) and the Functional Assessment of Cancer Therapy for Breast cancer (FACT-B). A total of 321 participants' data was analyzed using descriptive analyses, multiple regression, and structural equation modeling.

RESULTS

Negative illness perception was greater in participants currently receiving chemotherapy (p=0.044) or had received chemotherapy in the past (p=0.006). Positive illness perception was lower in older participants (p=0.001) or those who had received chemotherapy (p=0.018). Negative illness perception had a direct effect on a low sense of well-being (p<0.001). Perceived social support had a significant mediation effect on the relationship between negative/positive illness perception and sense of well-being (p<0.001).

CONCLUSION

Significant relationships between illness perception and sense of well-being were observed in breast cancer patients. Strengthening patients' perceived social support would be helpful in improving their sense of well-being.

Effect of programmed exercise on perceived stress in middle-aged and old women: A meta-analysis of randomized trials

OBJECTIVE

To clarify the effect of programmed exercise (PE), performed for at least six weeks, on perceived stress (PS) in middle aged and old women.

METHODS

A structured search was carried out in PubMed, Embase, Cochrane Library, Scielo, Web of Science and Scopus, from database inception through January 10, 2018, without language restriction. The US, UK, and Australian clinical trials databases were also searched. The search included a combination of the terms "programmed exercise", "perceived stress", "menopausal women" and "randomized controlled trial" (RCTs). PE was classified according to duration as "mid-term exercise intervention" (MTEI; mean duration 6 months), and "long-term exercise intervention" (LTEI; mean duration 12 months). Mean ± standard deviations of changes in PS scores, as assessed with different questionnaires, were calculated as standardized mean differences (SMDs) and used as effect size for meta-analysis. SMDs of PS after intervention were pooled using a random-effects model. Study quality and bias risk were assessed with the Cochrane tool.

RESULTS

Five RCTs that studied midlife and older women (mean age 47.0 ± 1.7 years minimum to 71.8 ± 5.6 maximum) were included in the meta-analysis. There was no significant effect of PE on PS score (SMD: -0.16; 95% CI: -0.43 to 0.11). In subgroup analyses, there was no significant effect of PE on PS with mid-term interventions (SMD: - 0.17; 95% CI: -0.59 to 0.25) nor with long-term interventions (SMD: -0.02; 95% CI: -0.42 to 0.38) as compared with controls.

CONCLUSION

PE of low to moderate intensity does not improve PS in midlife and older women.

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

The 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.

Physical activity and perceptions of stress during the menopause transition: A longitudinal study

The transition to menopause is a critical period of significant biopsychosocial change. The purpose of this study was to examine the influence of the transition to menopause and volume of physical activity on levels of perceived stress over five years in 102 healthy middle-aged women. Questionnaire and accelerometer data were analyzed using linear mixed models. Adjusting for age and body mass index, there were no significant effects of menopause status or time on perceived stress. Independent of menopause status, minutes per week of vigorous activity was associated with lower perceived stress in years 1 and 2 of the study.

A path analysis of stress and premenstrual symptoms in Korean international and Korean domestic students

AIMS

To identify the relationships between perceived stress, acculturative stress and premenstrual symptoms, among other associated factors (e.g. depressive symptoms, coping self-efficacy, perceived social support) of premenstrual symptoms suggested in the literature by testing the conceptual framework of the 'Stress and Premenstrual Experience Model: Women in Cultural Transition'.

BACKGROUND

Level of perceived stress has been cited as a major influencing factor for women's premenstrual symptoms; however, how these two elements are related, including possible mediators and moderators, remains unclear.

DESIGN

A longitudinal causal-comparative web-based study design.

METHODS

Data collection occurred between November, 2014 - February, 2015. The convenience sampling method was used to recruit 98 Korean international students and 89 Korean domestic students. Weekly surveys were conducted for 10 weeks to capture women's levels of perceived stress, acculturative stress and premenstrual symptoms from two menstrual cycles. The survey data collected during the premenstrual phase was analysed using path analyses.

RESULTS/FINDINGS

The hypothesized pathways based on the conceptual model were partially supported in the study. Depressive symptoms were a partial mediator between perceived stress and premenstrual symptoms and between acculturative stress and symptoms in Korean international students. The perceived social support was a moderator between perceived stress and premenstrual symptoms in Korean domestic students.

CONCLUSION

This study proposes a revised conceptual model that will contribute to the understanding of stress and premenstrual symptom severity in women in the acculturation process and concludes with suggestions and implications for future nursing practice and research.

Validation of the Perceived Stress Scale in a community sample of older adults

BACKGROUND

Three versions of Perceived Stress Scale (PSS-14, PSS-10, and PSS-4) are among the most widely used measures of stress. The aim of the current study was to validate this instrument in a sample of nondemented older adults to facilitate studies of the impact of stress on health.

METHODS

Seven hundred sixty-eight nondemented adults over the age of 70 years completed the PSS-14 questionnaire and other neuropsychological tests. Exploratory factor analysis was used to determine the underlying factor structure of all PSS versions, and confirmatory factor analysis was used to test the construct validity of factors. The internal consistency reliability of the scales was assessed using Cronbach's alpha, and concurrent validity was evaluated by examining PSS relation with age, gender, depression, anxiety, and Positive Affect and Negative Affect Schedule.

RESULTS

A two-factor model was the optimal fit for the 14-item and 10-item versions of PSS. For PSS-14, all items' loadings exceeded 0.4 for one of the two factors except item 12. Therefore, we studied a 13-item version of PSS and 10-item and 4-item subsets representing PSS-10 and PSS-4. Internal consistency coefficients were satisfactory for the full scale of PSS-13 and PSS-10 but not for PSS-4. Women reported higher levels of stress than men. Higher levels of total PSS scores showed association with higher levels of depression, anxiety, and negative affect, and lower level of positive affect.

CONCLUSIONS

The 13-item and 10-item versions of PSS may be used to understand the experience of stress among older adults.
