    Risk factors for the development of osteoarthritis in middle-aged women
    (2022) Blumel, Juan E.; Aedo, Socrates; Arteaga, Eugenio; Vallejo, Maria S.; Chedraui, Peter
    Background: Osteoarthritis (OA) is a health problem affecting millions of individuals worldwide. Aim: To evaluate risk factors for hip and knee osteoarthritis (OA) in women aged 40 to 59 years. Material and Methods: Analysis of a prospective cohort of 1159 women attending preventive health care programs and followed during 28 years. They underwent a clinical and laboratory evaluation from 1990 to 1993. The diagnosis of OA was retrieved from registries of a special program for osteoarthritis in 2020. Results: Twenty four percent of participants developed osteoarthritis during the follow-up. At the beginning of the study and compared with women without OA, they were older (median [interquartile range or IQR]: 49.6 [8.5] and 47.2 [8.2] years respectively), had a higher body mass index (26.3 [5.3] and 25.1 [5.3] respectively), and a higher frequency of jobs with low qualification (76 and 62% respectively). The presence of type 2 diabetes mellitus, chronic hypertension, a previous history of alcohol or cigarette consumption, postmenopausal status and lipid and glucose blood levels did not differ between women with or without OA. Cox regression showed a final model that incorporates body mass index (hazard ratio (HR): 1.04; 95% confidence intervals (CI): 1.01-1.07), age (HR: 1.05; 95% CI: 1.03-1.08) and having an unqualified job (HR: 1.88; 95% CI: 1.43-2.47) as risk factors for OA. Conclusions: Obesity and the type of job are the most relevant risk factors found for OD: both may be modified with proper care. (Rev Med Chile 2022; 150: 46-53)

    Severe menopausal symptoms linked to cognitive impairment: an exploratory study
    (2024) Calle, Andres; Blumel, Juan E.; Chedraui, Peter; Vallejo, Maria S.; Belardo, Alejandra; Dextre, Maribel; Elizalde-Cremonte, Alejandra; Escalante, Carlos; Espinoza, Maria T.; Gomez-Tabares, Gustavo; Monterrosa-Castro, Alvaro; Nanez, Monica; Ojeda, Eliana; Rey, Claudia; Rodriguez, Doris; Rodrigues, Marcio A.; Salinas, Carlos; Tserotas, Konstantinos; Aedo, Socrates
    Objective: To evaluate the association between menopausal symptoms and cognitive decline in postmenopausal women. Methods: This was a subanalysis of a cross-sectional, observational study conducted among women attending gynecological consultations across nine Latin American countries. The survey involved late postmenopausal women who were asked to complete a general questionnaire and the Menopause Rating Scale (MRS) to assess menopausal symptoms, with the Montreal Cognitive Assessment used to evaluate cognitive function as an outcome. A Montreal Cognitive Assessment score of less than 21 was used to define women with mild cognitive impairment (MCI). Results: The study included 1,287 postmenopausal women with a mean age of 55.5 years and a mean body mass index of 26.3 kg/m2. On average, participants had 13.8 years of education and 2.3 +/- 1.8 children, with 72.8% reporting having a partner. Additionally, 36.7% ever used menopausal hormone therapy. Regarding lifestyle factors, 50.3% engaged in a sedentary lifestyle, whereas 70.5% had never smoked. 15.3% of women had MCI exhibited significantly more intense menopausal symptoms compared with those without MCI (MRS total score 15.24 +/- 12.58 vs 10.53 +/- 8.84, respectively, P < 0.001). Logistic regression analysis revealed a significant association between severe menopausal symptoms (MRS total score >= 14 points) and MCI (odds ratio [OR], 1.74; 95% CI, 1.25-2.42). Conversely, a lower body mass index (OR, 0.96; 95% CI, 0.95-0.98), sexual activity (OR, 0.70; 95% CI, 0.51-0.96), physical exercise (OR, 0.55; 95% CI, 0.39-0.76), menopausal hormone therapy use (OR, 0.36; 95% CI, 0.24-0.55), and higher educational level (OR, 0.31; 95% CI, 0.21-0.46) were associated with lower odds for MCI. Conclusion: Severe menopausal symptoms in postmenopausal women were associated with cognitive impairment. This study highlights the intricate interplay between hormonal, lifestyle, and sociodemographic factors and cognitive health.
