IMPORTANCE Estrogens have neuroprotective and antidepressive effects; however, associations between indices of reduced endogenous estrogens and risk for postmenopausal depression have not been systematically explored. OBJECTIVE To investigate the association of age at menopause and the duration of the reproductive period with the risk for depression among postmenopausal women with naturally occurring menopause. DATA SOURCES A search strategy for use of MEDLINE was developed (through January 1, 2015) using the key terms menopause, climacteric, reproductive period, depression, and mood disorders. References of included studies and reviews were also screened; authors were contacted to maximize synthesized evidence. STUDY SELECTION A total of 12 323 articles, without language restriction, were screened by pairs of reviewers to identify observational studies related to the study hypothesis; 14 studies were eligible for meta-analysis. DATA EXTRACTION AND SYNTHESIS Pairs of reviewers independently extracted information on study design and type of analysis by participants' characteristics and methods of depression ascertainment. Study quality was assessed using the Newcastle-Ottawa Scale, and fixed-or random-effects models were implemented. MAIN OUTCOMES AND MEASURES Pooled-effect estimates for depression, defined by psychiatric evaluation or validated instruments, by age at menopause and duration of the reproductive period. RESULTS The 14 studies included in the meta-analysis represented 67 714 women. An inverse association (reported as odds ratio [OR]; 95% CI of 2-year increments) with depression in postmenopausal women was shown for increasing age at menopause (0.98; 0.96-0.99 [67 434 unique participants; 13 studies]) and duration of the reproductive period (0.98; 0.96-0.99 [54 715 unique participants; 5 studies]). Menopause at age 40 or more years compared with premature menopause was associated with a 50% decreased risk for depression (3033 unique participants; 4 studies). Pooling of studies examining severe depression showed a 5% decrease in risk of severe depression with increasing (2-year increment) age at menopause (52 736 unique participants; 3 studies); sensitivity analysis of studies controlling for past depression revealed similar results for age at menopause (0.98; 0.96-1.00 [48 894 unique participants; 3 studies). No heterogeneity or publication bias was evident in the main analyses. CONCLUSIONS AND RELEVANCE Longer exposure to endogenous estrogens, expressed as older age at menopause and longer reproductive period, is associated with a lower risk of depression in later life. Identifying women at higher risk for depression due to early menopause who could benefit from psychiatric intervention or estrogen-based therapies could be useful in the clinical setting.

To investigate the association of dietary habits with cognitive function among elders (>65 years). Complete sociodemographic, dietary information, serum measurements, and Mini-Mental State Examination (MMSE) assessments were available for 237 elderly men and 320 women residing in Velestino, Greece (a rural Greek town). All models were adjusted for age, education, social activity, smoking, depression symptomatology (using the Geriatric Depression Scale), MedDietScore (range 0-55), and metabolic syndrome. About 49.8% men and 66.6% women had MMSE scores <24, with a mean MMSE score of 22.7±4.43 and 21.1±4.73, respectively. Adherence to the Mediterranean diet was moderate (mean MedDietScore of 34.1±3.25 in men and 35.1±2.48 in women). Indicative cognitive impairment (MMSE score <24) was positively associated with age and low education in women and with depressive symptoms, low education status, and low social activity in men. Adherence to the Mediterranean diet was positively associated with MMSE score in men (P=.02), but inversely associated in women (P=.04). Concerning the food groups studied, intake of pulses, nuts, and seeds was associated with lower likelihood of having MMSE score<24 in men (P=.04). Only the Mediterranean dietary pattern showed a significant association with MMSE score positive for cognitive impairment (i.e., protective in men, but not in women), while individual food groups or nutrients did not achieve significance. The latter findings support the role of whole diet in the prevention of mental disorders, and state a research hypothesis for a sex-diet interaction on cognitive function among elders.

At present, COH for IVF does not seem to impart increased breast cancer risk. Longer follow-up periods, comparisons versus infertile women, subgroup analyses aiming to trace vulnerable subgroups, adjustment for various confounders and larger informative data sets are needed before conclusive statements for the safety of the procedure are reached.
