RESUMO
People tend to select romantic partners who belong to the same social group as themselves (i.e., endogamy). However, there is limited research on the proximal psychological motivations for choosing endogamous relationship partners. The purpose of this research was to develop a measure of motivations for endogamous relationship preferences and to assess whether such motivations were associated with actual dating experiences and attitudes toward endogamy across four common social categories: race and/or ethnicity, religion, social class, and education. Data from an online sample of participants (Study 1, n = 341) were used to generate items assessing motivations for endogamous relationship preferences. This initial set of items was administered to a new sample of participants (Study 2, n = 193) to establish the component structure of the measure and to examine whether the motivational components were associated with participants' past exogamous dating experiences as well as the perceived importance of dating within one's own racial and/or ethnic, religious, socioeconomic, and educational group. Endogamy motivations characterized by intergroup prejudice were the strongest and most consistent correlates of endogamous relationships and the perceived importance of endogamy. Study 3 (n = 332) replicated the component structure of the measure and the general pattern of associations documented in Study 2, and provided evidence for the measure's construct validity. The overall findings suggest that intergroup prejudice partially explains preferences for endogamous relationships.

Sex differences in religiosity are cross-culturally common and robust, yet it is unclear why sex differences in some cultures are larger than in others. Although women are more religious than men in most countries, religions frequently provide asymmetrical benefits to men at the expense of women. Two global analyses (51 countries and 74 countries) found that country-level gender equality was consistently and negatively associated with religiousness (i.e. religious attendance, reported importance of God and frequency of prayer) for men, more than for women, leading to a larger sex difference in religiousness in more gender-equal countries. Results were especially robust for religious attendance, and hold accounting for country-level wealth, as well as individuals' religious affiliation, the moralization of sexuality, age and education level. We interpret results through a rational choice lens, which assumes that people are more drawn to religion when it is consistent with their reproductive goals.

Background: Evidence suggests that a combination of biological and social factors influence risk of dementia differently for women and men. In healthy older women, several factors may contribute to changes in cognition. Objective: Describe the characteristics associated with variation in cognition in a sample of cognitively healthy older Panamanian women. Methods: The study includes cross-sectional analyses of cognitive domains at baseline (n = 357) and 17-month (SD = 2.0) follow-up (n = 200) for women aged 60 years and older enrolled in the Panama Aging Research Initiative-Health Disparities (PARI-HD) study. Instruments included clinical questionnaires, physiological measures, and a neuropsychological test battery assessing global cognition and seven cognitive domains. Multiple regression analyses examined the associations between demographic and clinical characteristics and cognition at baseline. Repeated measures analyses were used to investigate changes in cognition from baseline to follow-up. Results: On average, participants were 68.6 years of age (SD = 5.9) with 16.1 years of education (SD = 4.7). Age, income, and education showed robust associations with baseline cognition. Subjective cognitive impairment was associated with lower performance in global cognition, verbal learning, and memory domains. Only performance in the attention domain decreased at follow-up, and subjective health state and depressive symptoms significantly predicted the change in attention. Discussion: Our study findings contribute to the investigation of cognitive health in older Hispanic women and to the understanding of sociodemographic and health-related factors associated with cognitive decline and the progression to cognitive impairment and dementia.

RESUMO
Background: A growing body of evidence points to potential risks associated with polypharmacy (using ≥5 medications) in older adults, but most evidence is derived from studies where racial and ethnic minorities remain underrepresented among research participants. Objective: Investigate the association between polypharmacy and cognitive function, subjective health state, frailty, and falls in Hispanic older adults. Methods: Panama Aging Research Initiative-Health Disparities (PARI-HD) is a community-based cohort study of older adults free of dementia at baseline. Cognitive function was measured with a neuropsychological test battery. Frailty assessment was based on the Fried criteria. Subjective health state and falls were self-reported. Linear and multinomial logistic regression analyses were used to examine association. Results: Baseline evaluations of 468 individuals with a mean age of 69.9 years (SDâ=â6.8) were included. The median number of medications was 2 (IQR: 1-4); the rate of polypharmacy was 19.7% (95% confidence interval [CI]â=â16.1-23.3). Polypharmacy was inversely associated with self-rated overall health (bâ=-5.89, pâ<â0.01). Polypharmacy users had 2.3 times higher odds of reporting two or more falls in the previous 12 months (odds ratio [OR]â=â2.31, 95% CIâ=â1.06-5.04). Polypharmacy was independently associated with Fried's criteria for pre-frailty (ORâ=â2.90, 95% CIâ=â1.36-5.96) and frailty (ORâ=â5.14, 95% CIâ=â1.83-14.42). Polypharmacy was not associated with cognitive impairment. Conclusions: These findings illustrate the potential risks associated with polypharmacy among older adults in Panama and may inform interventions to improve health outcomes in this population.

Snake venom neutralization potency tests are required for quality control assessment by manufacturers and regulatory authorities. These assays require the use of large numbers of mice that manifest severe signs associated with pain and distress and long periods of suffering. Despite this, many animals make a full recovery; therefore, the observation of clinical signs as a predictor of animal death is highly subjective and could affect the accuracy of the results. The use of a more objective parameter such as body temperature measurement could help establish a humane endpoint that would contribute to significantly reducing the suffering of large numbers of animals. We determined the temperature drop in BALB/c mice exposed to the mixtures of Bothrops asper or Lachesis stenophrys venom and a polyvalent antivenom by using an infrared thermometer. Our data show that, based on the temperature change from baseline, it is possible to predict which animals will survive during the first 3 h after inoculation. The data provided in this study may contribute to future reductions in animal suffering, in concordance with general trends in the use of laboratory animals for the quality control of biologicals.

Background: The COVID-19 pandemic was characterized by global increases in depression, anxiety, and stress symptoms. Previous studies have shown that resilience mitigates these symptoms, however there is limited research exploring the link between resilience and mental illness during the COVID-19 pandemic in Central America. Objective: To examine the role of resilience as it relates to the perceived effect of the pandemic on mental health symptoms. Methods: A sample of 480 adults in Panama were recruited from March to May 2021 to complete an online survey. The online survey consisted of sociodemographic questions and scale measures assessing depression, anxiety and stress symptoms, resilience, and social support. Results: Results indicated that resilience mediated the relationship between the perceived effect of the COVID-19 pandemic and mental health symptoms; participants who felt more personally affected by the pandemic reported more depression, anxiety, and stress symptoms via decreased resilience. Further analyses revealed that resilience was moderated by sex and social support, showing that the indirect effect of resilience was greater for women and individuals who perceived low social support. Discussion: These findings contribute to a growing body of research documenting the adverse effects of the COVID-19 pandemic on mental health and reveal potential mechanisms through which pandemic-related distress decreases resilience, thereby increasing symptoms of mental illness.
RESUMO
Background: The impact of the COVID-19 pandemic and the associated restrictions on mental health is being studied. Objective: To analyze the psychosocial response to the COVID-19 pandemic in adults residing in Panama. Methods: A community sample of 480 adult residents of Panama completed a survey that included sociodemographic questions, COVID-19 related questions (e.g., health concerns regarding the virus, knowledge and behaviors in biosafety) and scales of stress, anxiety, depression, prosocial behavior, resilience, perceived social support, and insomnia. Results: Most of the participants (>60%) reported being negatively affected by the pandemic. Women experienced greater depression, anxiety, and stress symptoms than men, and age was negatively associated with depression, anxiety, and stress symptoms. Self-perceived health status and self-perceived social support were negatively associated with depression, anxiety, and stress symptoms. Self-perceived social isolation was positively associated with depression, anxiety, and stress symptoms. Psychiatric illness and insomnia were positively associated with depression, anxiety, and stress symptoms, whereas psychological resilience was negatively associated with depression, anxiety, and stress symptoms. Discussion: These results corroborate other studies regarding COVID-19 and mental health. This study highlights the need for specific prevention and intervention mechanisms related to the COVID-19 pandemic in different population groups. This is the first report of the psychological impact of COVID-19 in the general Panamanian population and one of the only studies in the Latin American region and, therefore, contributes to research in the Latino population and lower-middle income countries.
