Physical activity and healthy aging

A 16-week multicomponent exercise training program improves menopause-related symptoms in middle-aged women. The FLAMENCO project randomized control trial

OBJECTIVE

To investigate the influence of a supervised multicomponent exercise training program on menopause-related symptoms, particularly vasomotor symptoms (VMS), in middle-aged women.

METHODS

A total of 112 middle-aged women (mean age 52 ± 4 y old, age range 45-60 y) from the FLAMENCO project (exercise [n = 59] and counseling [n = 53] groups) participated in this randomized controlled trial (perprotocol basis). The exercise group followed a multicomponent exercise program composed of 60-minute sessions 3 days per week for 16 weeks. The 15-item Cervantes Menopause and Health Subscale was used to assess the frequency of menopause-related symptoms.

RESULTS

After adjusting for body mass index and Mediterranean diet adherence, the subscales measuring menopause-related symptoms and VMSs decreased 4.6 more in the exercise group compared to the counseling group (between-group differences [B]: 95% CI: -8.8 to -0.2; P  = 0.040). The exercise group also showed significant improvements in the subscales of couple relationships (between-group differences [B]: -1.87: 95% CI: -3.29 to - 0.45; P  = 0.010), psychological state (between-group differences [B]: -2.3: 95% CI: -5 to -0.2; P  = 0.035), and VMSs (between-group differences [B]: -4.5: 95% CI: -8.8 to -0.2; p  = 0.040) in the Cervantes Menopause and Health Subscale compared with the counseling group.

CONCLUSIONS

A 16-week multicomponent physical exercise program showed a positive effect on menopause- related symptoms especially in couple relationships, psychological state, and VMS, among 45 to 60 year old women.

Go for it! Exercising makes you happy and strong

Despite it is generally recognized the beneficial role of physical activity, large portion of the population is physically inactive. Very alarmingly, the well-known gender gap in physical activity is constantly increasing. Several barriers obstacle women to perform physical activity although exercising would be of paramount importance for their health in particular during pregnancy and menopause. In addition to physical health benefits, physical activity may influence well-being and resilience, greatly impacting on quality of life.

Here we explore the relationship between physical activity resilience and well-being in a group of 1107 female residents in the Metropolitan area of Naples.

Menopause research in Latin America

For 15 years, the Collaborative Group for Research of the Climacteric in Latin America (REDLINC) has been conducting research on several topics including age of menopause, metabolic syndrome, quality of life and climacteric symptoms, sexual dysfunction, poor quality of sleep and insomnia, and use of menopausal hormone therapy (MHT) in the general population and among gynecologists. Examples of data to have emerged for this region include the age of menopause (49 years), a high prevalence of metabolic syndrome (42.9%), and a new waist circumference cut-off value for the Latin American population (88 cm). Sexual dysfunction, poor quality of life, and sleep disorders have a prevalence of over 50%, with obesity and sedentary lifestyles affected importantly. MHT use is still low (12.5%), lack of prescription the most important reason for not using it, and gynecologists use MHT for themselves but do not recommend it often to their patients. The prevalence of alternative therapy use, recommended by physicians, is high.

The effect of programmed exercise over anxiety symptoms in midlife and older women: a meta-analysis of randomized controlled trials

We aimed to perform a systematic review and meta-analysis in order to clarify the effect of programmed exercise over mild-to-moderate anxiety symptoms (ASs) in midlife and older women. A structured search of PubMed, Medline, Web of Science, Scopus, Embase, Cochrane Library, Scielo, and the US, UK and Australian Clinical Trials databases (from inception through July 27, 2017) was performed, with no language restriction using the following terms: 'anxiety', 'anxiety symptoms', 'exercise', 'physical activity', 'menopause', and 'randomized controlled trial' (RCTs) in mid-aged and older women. We assessed RCTs that compared the effect of exercise for at least 6 weeks versus no intervention over ASs as outcome (as defined by trial authors). Exercise was classified according to duration as 'mid-term exercise intervention' (MTEI; for 12 weeks to 4 months), and 'long-term exercise intervention' (LTEI; for 6-14 months). Mean ± standard deviations of changes for ASs, as assessed with different questionnaires, were extracted to calculate Hedges' g and then used as effect size for meta-analyses. Standardized mean differences (SMDs) of ASs after intervention were pooled using a random-effects model. Ten publications were included for analysis related to 1463 midlife and older women (minimum age 54.2 ± 3.5 and maximum age 77.6 ± 5.4 years). Eight MTEIs were associated with a significant reduction of ASs (SMD = -0.42; 95% CI -0.81 to -0.02) as compared to controls. There was no reduction of ASs in seven LTEIs (SMD = -0.03; 95% CI -0.18 to 0.13). It can be concluded that MTEIs of low-to-moderate intensity seem to improve mild-moderate ASs in midlife and older women.

Prevalence of metabolic syndrome and its association with lifestyle and cardiovascular biomarkers among postmenopausal women in western Algeria

OBJECTIVE

To evaluate the prevalence of metabolic syndrome (MetS), its components, and their relationship with lifestyle, inflammation, and oxidative stress among postmenopausal Algerian women.

METHODS

A prospective cross-sectional survey was conducted among postmenopausal women at a clinic in Oran, Algeria, from March 1 to June 28, 2015. A diagnosis of MetS was made using the National Cholesterol Education Program Adult Treatment Panel III guidelines. Demographic, clinical, metabolic, inflammatory, dietary, and energy variables were assessed.

RESULTS

Among 183 participants, 106 (57.9%) were diagnosed with MetS. Components of MetS included hypertension (n=144, 78.7%), hyperglycemia (n=135, 73.8%), hypertriglyceridemia (n=125, 68.3%), abdominal obesity (n=123, 67.2%), and low levels of high-density lipoprotein cholesterol (n=121, 66.1%). Although daily energy expenditure was similar among the women with or without MetS, total energy intake was increased in the group with MetS (P<0.001). The following measures were also increased among women with MetS: saturated fatty acid intake (P<0.001), C-reactive protein (P=0.051), thiobarbituric acid reactive substances (P<0.001), and carbonyls (P<0.001). By contrast, decreased monounsaturated fatty acid intake (P=0.024) and catalase activity (P<0.001) were observed in this group.

CONCLUSION

Postmenopausal status could predict MetS, with inflammation and oxidative stress arising from an unhealthy lifestyle potentially increasing cardiovascular risk.

Age-related changes in skeletal muscle mitochondria: the role of exercise

Aging is associated with mitochondrial dysfunction, which leads to a decline in cellular function and the development of age-related diseases. Reduced skeletal muscle mass with aging appears to promote a decrease in mitochondrial quality and quantity. Moreover, mitochondrial dysfunction adversely affects the quality and quantity of skeletal muscle. During aging, physical exercise can cause beneficial adaptations to cellular energy metabolism in skeletal muscle, including alterations to mitochondrial content, protein, and biogenesis. Here, we briefly summarize current findings on the association between the aging process and impairment of mitochondrial function, including mitochondrial biogenesis and reactive oxygen species in skeletal muscle. We also discuss the potential role of exercise in the improvement of aging-driven mitochondrial dysfunctions.
