The revictimization of older Mexican women: understanding the accumulation of multiple victimizations throughout a lifetime

Background The victimization of women constitutes a human rights violation and a health risk factor. The central objectives of this study were to analyze the probability of revictimization among older adult Mexican women and to examine whether child abuse (CA) and/or intimate partner violence (IPV) are associated with a greater risk of elder abuse (EA) victimization. Methods We conducted a secondary data analysis of 18416 women 60 and older, based on data from the National Survey on the Dynamics of Household Relationships (2016), which is national and subnational representative. A descriptive analysis was carried out using retrospective self-reports of victimization experiences (CA, IPV, and EA). The prevalence of victimization and multiple victimizations in the various stages of the lives of women, as well as of revictimization among older adult women were obtained. Bayesian logistic regression models were used to examine the associations between victimization, multiple victimization, and EA victimization. Results A total of 17.3% of the older adult women reported EA in the last year; of these, 81.0% had been revictimized and 14.0% reported CA, IPV, and EA. The risk of EA rose among women who reported a combination of psychological and sexual CA, and psychological, physical and sexual CA and psychological and sexual IPV, and a psychological, economic, physical and sexual IPV. EA was higher among women who had suffered more than one type of violence. Conclusion CA and IPV, particularly sexual abuse and psychological violence, can be risk factors for EA. Screening tools used to prevent and detect EA should include questions about domestic violence over the course of a person’s lifetime.

Expressive Power of Anti-Violence Legislation

abstract We know more about why laws on violence against women (vaw) were adopted than about how much and in what ways these laws affect society. The authors argue that even weakly enforced laws can contribute to positive social change. They theorize the expressive power of vaw legislation, and present evidence for a cautiously optimistic assessment of current trends on violence against women and the ways that vaw laws affect social norms. Focusing on a time of major legal change related to vaw in Mexico, this article explores trends in behavior and attitudes related to violence by analyzing four waves of the National Survey on the Dynamics of Household Relations (endireh), which include detailed interviews with thousands of Mexican women. The authors find that over this period, the share of women experiencing intimate-partner abuse declined, attitudes condoning violence shifted, reporting rates rose, and most women learned about legislation to protect their rights. These changes are consistent with the authors’ expectations about the expressive power of anti-violence legislation.

Intensive Medical Nutrition Therapy Alone or with Added Metformin to Prevent Gestational Diabetes Mellitus among High-Risk Mexican Women: A Randomized Clinical Trial

The aim of this study was to examine the efficacy of intensive medical nutrition therapy (MNT) plus metformin in preventing gestational diabetes mellitus (GDM) among high-risk Mexican women. An open-label randomized clinical trial was conducted. Inclusion criteria were pregnant women with three or more GDM risk factors: Latino ethnic group, maternal age >35 years, body mass index >25 kg/m2, insulin resistance, and a history of previous GDM, prediabetes, a macrosomic neonate, polycystic ovarian syndrome, or a first-degree relative with type 2 diabetes. Women before 15 weeks of gestation were assigned to group 1 (n = 45): intensive MNT-plus metformin (850 mg twice/day) or group 2 (n = 45): intensive MNT without metformin. Intensive MNT included individual dietary counseling, with ≤50% of total energy from high carbohydrates. The primary outcome was the GDM incidence according to the International Association of Diabetes Pregnancy Study Groups criteria. There were no significant differences in baseline characteristics and adverse perinatal outcomes between the groups. The GDM incidence was n = 11 (24.4%) in the MNT plus metformin group versus n = 7 (15.5%) in the MNT without metformin group: p = 0.42 (RR: 1.57 [95% CI: 0.67–3.68]). There is no benefit in adding metformin to intensive MNT to prevent GDM among high-risk Mexican women. Clinical trials registration: NCT01675310.

Body mass index and vitamin D as risk factors for the development of uterine leiomyomas in Mexican women

Objective: The objective of the present study was to determine if body mass index and vitamin D levels are risk factors for the development of uterine leiomyomas in Mexican women. Methods: A cross-sectional study was designed. Inclusion criteria were women between 20 and 55 years with a suspect of uterine leiomyomas. Transvaginal ultrasonography was made to confirm the diagnosis and clinical variables were collected. Vitamin D levels were measured in serum by chemiluminescence immunoassay. Binary linear regression analysis was conducted to assess the predictors of uterine leiomyomas. Results: A total of 106 patients were evaluated, the mean age was 41.4 ± 8.0 years. The serum levels of vitamin D were insufficient in 94 (88.7%) and 82 (77.3%) has overweight or obesity. However, only 50 (47.2%) of participants have a diagnostic of uterine leiomyomas. BMI not increased the probability of having insufficient levels of vitamin D or uterine leiomyomas. Only, age (> 45 years) and levels of vitamin D (<30 ng/mL) were predictors of uterine leiomyomas (OR 10.345, 95% CI 2.737–39.095; p = 0.001; and OR 2.26, 95% CI 1.011–5.073; p = 0.014), respectively. Conclusions: Insufficient levels of vitamin D are common in Mexican women. Age and hypovitaminosis D are possible risk factors in the development of uterine leiomyomas in Mexican women.

Effect on weight of a homemade diet in women with overweight or obesity: A randomized controlled trial

The official dietetic guidelines for weight loss include the practice of “healthy eating”. However, such recommendations rarely take into account the cultural context. The aim of the present study was to measure the effect of recommending a traditional homemade diet (exemplified by typical meals consumed in Mexico) vs. recommending an iso-caloric healthy diet (represented by the eatwell plate) on the weight of Mexican women with overweight or obesity. Initially 159 women were randomly assigned to the homemade diet or the healthy diet and 30 women completed the intervention. The effect on weight of the recommended diet at 4, 8 and 12 weeks was determined by one-way analysis of variance and by random regression model. Participants on average reduced weight significantly throughout the intervention without statistical difference between the homemade diet and the healthy diet. This finding supports an anti-obesity strategy of recommending traditional diets in culturally recognised terms.

Oxidative Stress Risk Is Increased with a Sedentary Lifestyle during Aging in Mexican Women

Oxidative stress (OS) increases during the human aging process, and the sedentary lifestyle could be a prooxidant factor. In this study, we determine the effect of sedentary lifestyle on OS during the aging process in Mexican women. A longitudinal study of two-year follow-up was carried out with 177 community-dwelling women (40-69 y) from Mexico City. We measured as OS markers plasma malondialdehyde, erythrocyte glutathione peroxidase (GPx) and superoxide dismutase (SOD), total plasma antioxidant status, uric acid level, antioxidant gap, and SOD/GPx ratio. To define OS using all the markers, we defined cut-off values of each parameter based on the 90th percentile of young healthy subjects and, we calculated a stress score (SS) ranging from 0 to 7, which represented the intensity of the marker modifications. All the women answered a structured questionnaire about prooxidant factors, including physical activity specially the type of activity, frequency, and duration, and they answered Spanish versions of self-assessment tests for establishing dysthymia and insomnia as potential confounders. Principal component and Poisson regression analysis were used as statistical tools, being two-year OS the primary outcome. The OS was considerate as SS ≥ 4 and sedentary lifestyle as <30 min/day of physical activity, beside several prooxidant factors and age that were covariables. SS is higher in sedentary lifestyle women after the two-year follow-up; although, the difference was statistically significant only in older women. Four principal components were associated with the OS, and 7 out of 8 prooxidant factors were important for the analysis, which were included in the Poisson model. The predictive factors for OS were the sedentary lifestyle (adjusted PR = 2.37, CI95%: 1.30–4.30, p < 0.01 ), and age, in which the risk increases 1.06 (CI95%:1.02–2.11, p < 0.01 ) by each year of age. Our findings suggest that a sedentary lifestyle increases the OS during the aging in Mexican women.

Cervical Squamous Intraepithelial Lesions Are Associated with Differences in the Vaginal Microbiota of Mexican Women

Human papillomavirus (HPV) plays a critical role in cervical carcinogenesis but is not sufficient for cervical cancer development, indicating the involvement of other factors. The vaginal microbiota is an important factor in controlling infections caused by HPV, and, depending on its composition, it can modulate the microenvironment in vaginal mucosa against viral infections.
