Background: Breast cancer incidence in the United States is lower in Hispanic/Latina (H/L) compared with African American/ Black or Non-Hispanic White women. An Indigenous American breast cancer-protective germline variant (rs140068132) has been reported near the estrogen receptor 1 gene. This study tests the association of rs140068132 and other polymorphisms in the 6q25 region with subtype-specific breast cancer risk in H/Ls of high Indigenous American ancestry. Methods: Genotypes were obtained for 5,094 Peruvian women with (1,755) and without (3,337) breast cancer. Associations between genotype and overall and subtype-specific risk for the protective variant were tested using logistic regression models and conditional analyses, including other risk-associated polymorphisms in the region. Results: We replicated the reported association between rs140068132 and breast cancer risk overall ...

Evolutionary psychologists have hypothesized that men and women possess both long-term and short-term mating strategies, with men's short-term strategy differentially rooted in the desire for sexual variety. In this article, findings from a cross-cultural survey of 16,288 people across 10 major world regions (including North America, South America, Western Europe, Eastern Europe, Southern Europe, Middle East, Africa, Oceania, South/Southeast Asia, and East Asia) demonstrate that sex differences in the desire for sexual variety are culturally universal throughout these world regions. Sex differences were evident regardless of whether mean, median, distributional, or categorical indexes of sexual differentiation were evaluated. Sex differences were evident regardless of the measures used to evaluate them. Among contemporary theories of human mating, pluralistic approaches that hypothesize ...

The objective of this study is to examine the prevalence and factors associated with frailty in Peruvian Navy Veteran's older adults and family members. A total of 311 non-institutionalized men and women aged 60 years and older, from the Geriatrics Service of the Peruvian Navy Medical Center (Centro Médico Naval “Cirujano Mayor Santiago Távara”) were assessed between May and October 2010. Frailty was defined as having two or more of the following components: 1) unintentional weight-loss, 2) weakness (lowest 20% in grip-strength), 3) self-reported exhaustion, and 4) slow walking speed (lowest 20% 8-meter walk-time in seconds). Additionally, information on socio-demographic factors, medical conditions, depressive symptoms, disability, and cognitive function were obtained. Of the 311 participants, 78 (25.1%) were not frail, 147 (47.3%) were pre-frail, and 86 (27.8%) were frail. Using ...

STUDY OBJECTIVES: We sought to evaluate the construct validity and factor structure of the Spanish-language version of the Pittsburgh Sleep Quality Index (PSQI) among pregnant Peruvian women. METHODS: A cohort of 642 women were interviewed at ≤ 16 weeks of gestation. During interview, we ascertained information about lifestyles, demographics, sleep characteristics, and mood symptoms. Stress induced sleep disturbance, depressive symptoms, and anxiety symptoms were evaluated using the Ford Insomnia Response to Stress Test (FIRST), Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder-7 (GAD-7) assessment scales, respectively. Consistency indices, exploratory and confirmatory factor analyses, correlations, and logistic regressions were used. RESULTS: Both exploratory and confirmatory factor analyses indicated a three-factor solution: sleep quality, sleep efficiency, and...

Abdominal obesity (AO) is a serious public health threat due to its increasing prevalence and effect on the development of various non-communicable diseases. A multilevel analysis of the 2019 Demographic and Family Health Survey (ENDES in Spanish) using the Latin American Diabetes Association (ALAD in Spanish) cut-off points was carried out to evaluate the individual and contextual factors associated with AO in Peru. A total of 30,585 individuals 18 years and older were included in the analysis. The prevalence of AO among Peruvians in 2019 was 56.5%. Individuals of older age (aOR 4.64; 95% CI: 3.95-5.45), women (aOR 2.74; 95% CI: 2.33-3.23), individuals with a higher wealth index (aOR 2.81; 95% CI: 2.40-3.30) and having only secondary education (aOR 1.45; 95% CI: 1.21-1.75) showed increased odds of presenting AO compared to their peers. At a contextual level, only the Human Development I...

As part of the International Sexuality Description Project, 16,954 participants from 53 nations were administered an anonymous survey about experiences with romantic attraction. Mate poaching - romantically attracting someone who is already in a relationship - was most common in Southern Europe, South America, Western Europe, and Eastern Europe and was relatively infrequent in Africa, South/Southeast Asia, and East Asia. Evolutionary and social-role hypotheses received empirical support. Men were more likely than women to report having made and succumbed to short-term poaching across all regions, but differences between men and women were often smaller in more gender-egalitarian regions. People who try to steal another's mate possess similar personality traits across all regions, as do those who frequently receive and succumb to the poaching attempts by others. The authors conclude that ...

The aim of this descriptive, longitudinal and retrospective study was to determine epidemiological aspects of the classical rheumatoid arthritis in the Rheumatology Service of HCFAP between 1976 and 1992. Two hundred and six cases of classical rheumatoid arthritis were evaluated. The delay of the diagnosis was defined as the time from the onset of the symptoms to the diagnosis itself. There were 169 women (82.03%) and 37 men (17.97%). The mean age was 65 ± 14.43 years (mean ± DE) in men and 61 ± 14.44 years in women. Yhe larger on age group was 46-55 years old (23.30%) and the smaller 16-25 years old. On admission, 48.75 cases presented grade II function. Rheumatoid factor was positive in 70% (P<0,001). The increased frequency of new cases was recorded in 1988 (11.65%) and the decreased frequency in 1978 (2.42%). In the delay for reaching the incapacity, 52.38% was found to be in t...

Research shows that consumption correlates with the experience of subjective well-being. However, there is little literature on this phenomenon among young people. This exploratory study aims to know how university students perceive that consumption and brands intervene on subjective well-being and identify the elements they consider in their consumption behaviors aimed at obtaining well-being. A qualitative methodology of phenomenological design was used, with university students from the city of Lima. The analysis followed a process of descriptive coding. The experience of consumption and well-being reveals itself as a phenomenon relative to each person, in particular their sense of need and value framework about material goods, factors that seem to be modulated by their family environment. Young people find in purchase practices and brands a conduit to meet their social needs, specifi...

Despite the relevance of personalization in research in Political Communication, as well as other fields of study, there is a state of confusion in the literature on the concept. The main reason is that there is no consensus around a widely shared definition. In addition, the personalization of politics can be approached from different perspectives, corresponding to the main actors involved in the political processes, that is, the media system, the political system and the citizens. Consequently, the results and conclusions are varied and, even occasionally, disparate. Therefore, this lack of conceptual clarity represents a limitation for progressing in the study of personalization. Hence the aim of this research is to propose a definition serving as a reference for further studies on this phenomenon.

Objective: The study objective was to evaluate the safety and clinical and echocardiographic outcomes of a new surgical technique in adult patients diagnosed with a giant left atrium. Methods: We analyzed a cohort of patients who underwent left atrium reduction surgery between January 2016 and June 2020 performed by a specialized surgical team in 2 national reference centers in Lima, Peru. We assessed the major adverse valvular-related events and the New York Heart Association functional class as primary clinical outcomes. Also, our primary echocardiographic endings were the diameter, area, and volume of the left atrium. We assessed these variables at 3 time periods: baseline (t0), perioperative period (t1), and extended follow-up (t2: 12 ± 3.4 months). We carried out descriptive and bivariate exploratory statistical analysis for dependent measures. Results: We included 17 patients, 70....

The paper presents a review of the literature of news coverage on female presidential candidates. For this purpose, seven coverage frames are included: a) visibility, b) gender reiteration, c) mediation of the intimate sphere, personality, d) thematic agenda, e) tonality and f) particularities of the media. Finally, an operationalization proposal is formulated for each of the frames that could be used in future research that addresses these political figures. It is concluded that women are represented from their intimate sphere and femininity, characteristics that are far from being culturally appropriate for debate in the public and political arena.

The purpose of this study was to translate the Bedtime Procrastination Scale (BPS) into Spanish and to evaluate its psychometric properties. A sample of 419 students from three Peruvian universities participated in the study. Confirmatory factor analysis was conducted to evaluate the original model of the scale, which initially showed poor fit indices. Improved fit indices were obtained after removing reverse-scored item, χ²(5) = 9.240, CFI = .998, RMSEA = .045, TLI = .997, and SRMR = .013. The internal consistency of the scale, examined using the omega coefficient, was found to be satisfactory (ω = .86). Moreover, measurement invariance analysis supported gender invariance, indicating that the scale functions equivalently across male and female participants. Additionally, convergent validity was assessed by examining the correlations between the BPS and insomnia, as measured by the A...
