Menopause is often associated with an increase in depressive symptoms,
affecting up to 35% of postmenopausal women. These issues, often exacerbated by
hormonal fluctuations, sleep disorders, or age-related body changes, negatively
impact quality of life and lead to increased healthcare costs. In this context,
it is crucial to identify effective and accessible approaches to manage these
symptoms, particularly through nutritional interventions.
This study evaluates the impact of daily dark
chocolate consumption on depression and sleep quality in menopausal women aged
45 to 65. Additionally, it explores potential effects on anthropometric
parameters such as body mass index (BMI), weight, and waist circumference to
assess possible implications for overall physical health.
Dark Chocolate: A Natural Solution for
Depression in Menopausal Women?
Sixty menopausal women with mild to moderate depressive symptoms were selected
and randomly divided into two groups:
- Group 1: Daily consumption of 12 g of dark
chocolate (78% cocoa).
- Group 2: Daily consumption of 12 g of milk
chocolate.
The intervention lasted eight weeks, with evaluations using the Beck
Depression Inventory-II (BDI-II) to measure depression and the Pittsburgh Sleep
Quality Index (PSQI) to assess sleep quality. Anthropometric parameters were
also recorded.
The study revealed a
significant reduction in
depression scores in the group consuming dark chocolate, with an adjusted mean
difference of -2.3 (p = 0.003) and a moderate effect size (Cohen's d = -0.54).
However,
no significant improvement was observed between the two groups
regarding overall sleep quality or its subdomains. Similarly,
measurements of
weight, BMI, and circumferences (waist and hips) showed no significant
differences between the groups after the intervention.
Dark Chocolate: A Small Treat with Big Benefits
This study suggests that daily consumption of dark chocolate rich in
polyphenols can be an effective complementary method to reduce depressive
symptoms in menopausal women. However, no effects were observed on sleep
quality or physical health indices. These findings highlight the potential of
functional foods in nutritional recommendations, though further research is
needed to clarify the mechanisms of action, optimal dosages, and intervention
duration.
