RESUMEN

Animals in the wild continually experience changes in environmental and social conditions, which they respond to with behavioural, physiological and morphological adaptations related to individual phenotypic quality. During unfavourable environmental conditions, reproduction can be traded-off against self-maintenance, mediated through changes in reproductive hormone levels. Using the European badger (Meles meles) as a model species, we examine how testosterone in males and oestrogens in females respond to marked deviations in weather from the long-term mean (rainfall and temperature, where badger earthworm food supply is weather dependent), and to social factors (number of adult males and females per social group and total adults in the population), in relation to age, weight and head-body length. Across seasons, testosterone levels correlated postively with body weight and rainfall variability, whereas oestrone correlated positively with population density, but negatively with temperature variability. Restricting analyses to the mating season (spring), heavier males had higher testosterone levels and longer females had higher oestradiol levels. Spring oestrone levels were lower when temperatures were above normal. That we see these effects for this generally adaptive species with a broad bioclimatic niche serves to highlight that climatic effects (especially with the threat of anthropogenic climate change) on reproductive physiology warrant careful attention in a conservation context.

RESUMEN

Background: Hypertension awareness and control are understudied among older adults in middle-income countries, with limited work contextualizing awareness and control across layers of influence (individual to the community). Research on hypertension in Latin America is acknowledged as insufficient. Objectives: This study applies the socioecological model (SEM) to examine individual, interpersonal, institutional, and community factors related to hypertension awareness and control in older adults residing in Brazil and Colombia. It identifies groups of older adults more likely to be unaware of their condition and/or to have challenges achieving hypertension control. Methods: We analyzed International Mobility in Aging Study data of 803 community-dwelling adults 65-74 years from study sites in the two most populous countries in South America. The study framework was the socioecological model. Logistic regression models identified factors associated with hypertension awareness and control. Conclusions: Hypertension was prevalent in both samples (>70%), and awareness was high (>80%). Blood pressure control among diagnosed respondents was low: 30% in Brazil and 51% in Colombia. Factors across the socioecological model were associated with awareness and control, with notable differences across countries. Those with diabetes (OR 4.19, 95%CI 1.64-10.71) and insufficient incomes (OR: 1.85, 95%CI 1.03-3.31) were more likely to be aware of their hypertension. In Colombia, those reporting no community activity engagement were less likely to be aware compared to those reporting community activities. In Brazil, it was the opposite. Women (OR 1.66, 95%CI 1.12-2.46) and those reporting strolling shops and stores (OR 1.80, 95% CI 1.09-3.00) were significantly more likely to have their hypertension under control. In Brazil, those 70-75 were significantly less likely to have their hypertension under control compared to their younger counterparts. In Colombia, this was not observed. This paper highlights the importance of theory-based studies within unique Latin American contexts on hypertension and suggests novel opportunities for intervention.

RESUMEN

Obesity-related information in children with Autism Spectrum Disorder (ASD) is limited, and research findings are contradictory. Thus, this study aimed to use a nationwide non-clinical sample to examine the association of sociological factors with overweight status in children with ASD and reveal the degree of differences in the risk factors for overweight in children with and without ASD. The data for this cross-sectional study, based on the modified ecological system theory model, were obtained from the 2019 National Survey of Children's Health. The weighted logistic regressions were performed to determine the factors associated with overweight status in children with ASD, controlling for demographics, physical activity-related behaviors, and family and environmental conditions. A total of 529 children were identified (mean age 13.78 years, 83.21% boys). Two-parent households, less healthy parents and households, households with smokers, poor sleep quality, and greater participation in organized activities were associated with a higher likelihood of overweight in children with ASD (all P < 0.05). The determinants of obesity among children with ASD go beyond the individual level; family and community support are important. Therefore, greater attention should be directed toward the families of children with ASD and community-level administrative policies to improve quality of life by preventing or reducing obesity in children with ASD.

RESUMEN

PURPOSE: This prospective observational study examined the association of socioecological factors with quitting behavior among US adolescents who exclusively use electronic cigarettes (e-cigarettes). METHODS: We used data from past 30-day adolescent exclusive e-cigarette users (n = 243) participating in Wave 3 of the Population Assessment of Tobacco and Health study, who were then followed-up with approximately 12 months later for Wave 4. Weighted unadjusted and adjusted multivariate logistic regression models and structural equation modeling were performed to analyze the data. RESULTS: Adolescents were significantly less likely to quit e-cigarettes if they perceived that nicotine in e-cigarettes was "slightly/somewhat harmful" to health (adjusted odds ratio [aOR] = 0.38; 95% confidence interval [CI]: 0.16-0.90, p = .02). Similarly, adolescents who reported that someone else in their home owned an e-cigarette (aOR = 0.43 [95% CI: 0.19-0.94], p = .03) or important people in their life used e-cigarettes (aOR = 0.45 [95% CI: 0.21-0.95], p = .03) were significantly less likely to quit e-cigarettes. The structural equation modeling showed a direct significant relationship of individual-level (b = 0.206, p = .02) and interpersonal-level factors (b = 0.170, p = .04) with e-cigarette quitting behavior. DISCUSSION: Our findings suggest that individual-level (harm perception) and interpersonal-level (e-cigarette use at home and by important people) factors may play a significant role in e-cigarette quitting behavior among US adolescents.

RESUMEN

To understand the evolutionary ecology of disease dynamics, it is crucial to identify the environmental factors that mediate the spread and abundance of parasites and their vectors. However, human-mediated changes in the biotic and abiotic environment and intervention programs are intensifying in the past 30-40 years at a rate that masks the causal effect of the original ecological predictors. In this study, we used archived epidemiological data spanning over 100 years on malaria risk in Hungary to demonstrate that different associations exist between infection risk and environmental predictors during different phases of the elimination program. In the early 20th century, when malaria was quite common in the country and no defense program was operating, as predicted, there was a positive relationship between the area of flooded habitats and the intensity of malaria infection. In contrast, this relationship was absent during middle of the century, when an effective elimination program was already in effect. Furthermore, malaria morbidity in a given year was predicted by the degree of stagnant water cover of the previous year when considering the period before the launch of a drastic mosquito control program by dichloro-diphenyl-trichloroethane (DDT), whereas such relationship could not be revealed for a latter period. Our results highlight that human-induced alterations of the socioecological environment considerably reorganizes the ecological landscape of pathogens and their vectors.

RESUMEN

WHAT IS ALREADY KNOWN ON THIS TOPIC?: Different socioecological factors were associated with childhood pneumonia in Bangladesh. However, previous studies did not assess spatial patterns, and socioecological factors and spatial variation have the potential to improve the accuracy and predictive ability of existing models. WHAT IS ADDED BY THIS REPORT?: The spatial random effects were present at the district level and were heterogeneous. Average temperature, temperature variation, and population density may influence the spatial pattern of childhood pneumonia in Bangladesh. WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE?: The study results will help policymakers and health managers to identify the vulnerable districts, plan further investigations, help to improve proper resource allocation, and improve health interventions.

RESUMEN

BACKGROUND: Research is lacking on community and pharmacy-level factors that are associated with stocking buprenorphine. To address these gaps, this study applied a socio-ecological framework to estimate the association between community- and pharmacy-level factors and buprenorphine stocking among a sample of pharmacies in New York City. METHODS: A telephone survey recruitment strategy was used to administer surveys to 662 pharmacies on the New York City Naloxone Standing Order Pharmacy list in 2018. The survey assessed pharmacy-level factors of private spaces to consult with pharmacists, type of pharmacy (chain/independent), size of pharmacy, having buprenorphine in stock and being open on nights and weekends. Socio-ecological variables drawn from census tract and public health data consisted of racial and ethnic composition, rates of poverty, rates of people without insurance, and rates of overdose. Mixed effects logistic regression estimated odds ratios (OR) of carrying buprenorphine in stock after adjusting for socio-ecological and pharmacy-level factors. RESULTS: Fewer than half of the pharmacies reported having buprenorphine in stock (43.81% n = 290). Logistic regression analyses indicate that several pharmacy-level factors - the number of private spaces (aOR=1.67 95% CI=1.20, 2.32 p=.002), large size of the pharmacy (aOR=1.52 95% CI=1.04, 2.22, p=.032), having naloxone in stock (aOR=1.54, 95%CI=1.03, 2.32 p=.037), as well as neighborhood-level factors of higher rates of poverty (aOR=2.07 95%CI=1.07, 4.02 p<.001) and higher rates of uninsured residents were associated with carrying buprenorphine (aOR=0.23 95%CI=0.14,.38). CONCLUSIONS: Using a socio-ecological framework, this study identified inequities in pharmacy stocking of buprenorphine by neighborhood rates of health insurance. At the pharmacy level, increasing private spaces for consultation and encouraging co-stocking of naloxone with buprenorphine stocking may reduce inequalities in buprenorphine availability.

RESUMEN

This study examined the relationship between children's flourishing and socioecological factors, including individual and family characteristics. A total of 45,309 children were drawn from the 2011-2012 National Survey of Children's Health in the US (mean age = 13.6 years; male: 51.28%). An ordinary least square (OLS) regression was performed to examine the association between socioecological variables and flourishing. This study assessed children's individual needs (such as health, education, and emotional and behavioral development), their parents' parenting capacity (the ability to provide basic care and safety), and family factors (presence of community resources and family income). Children's individual characteristics, parent's capacities, and family functions were found to be significantly associated with children's flourishing. In conclusion, multilevel socioecological factors appeared to be associated with children's flourishing. Hence, parents' involvement in their children's physical activities, as well as family and social support, is crucial for children's flourishing. This study makes a significant contribution to the literature as research is lacking a correlation between socioecological factors and children's flourishing; in particular, very few studies have explored or investigated the manner by which children's socioecological health indicators and factors are associated with their flourishing.

RESUMEN

BACKGROUND: Adolescents are among the highest consumers of sugar-sweetened beverages (SSBs) in the United States. More research is needed to understand the relationship of multiple levels of influence on adolescent SSB intake across the socioecological model in a nationally representative sample. OBJECTIVE: This secondary analysis of cross-sectional data aims to explain variance in adolescent SSB intake by exploring the associations of adolescent demographic (ie, age, race/ethnicity, and parent socioeconomic status), intrapersonal (ie, behavioral intention, self-efficacy, and media perception), interpersonal (ie, social norms and perceived parenting practices), and home availability variables. DESIGN: This study included 1,560 adolescents who participated in the 2014 National Cancer Institute-sponsored cross-sectional Family, Life, Activity, Sun, Health, and Eating study. Descriptive statistics, analyses of variance, and stepwise multiple linear regression models were used to explore factors associated with SSB intake. In the stepwise regression, a 4-step model was analyzed with each subsequent step adding variables from different socioecological model levels. RESULTS: The final step that included 14 variables individually associated with SSB intake significantly predicted 16.5% of the variance in SSB intake. Four variables were associated with higher SSB intake in the final step when controlling for all other variables: male sex (ß=.066), non-Hispanic black vs non-Hispanic white (ß=.123), adolescent's report of having parents allow them to have SSBs on a bad day (ß=.150), and home SSB availability (ß=.263). Race/ethnicity other than Hispanic and/or non-Hispanic black vs non-Hispanic white was associated with lower intake (ß= -.092). CONCLUSIONS: When considering potential targets for multilevel behavioral interventions aimed at reducing adolescent SSB intake, emphasis on reducing SSB availability at home may be especially important. Furthermore, although adolescence is a period of increasing independence, parent influence on adolescent's health behaviors may also be a key intervention target. Home and parental SSB factors may be more important than targeting intrapersonal factors and social norms among adolescents.

RESUMEN

This study examined the effect of children's flourishing on the pandemic of obesity from various aspects such as age, gender, race, family, school, and community. By using a subsample of the 2011-2012 National Survey of Children's Health, the Flourishing scale analyses were performed with a total of 45,309 children. Childhood obesity was diagnosed by calculating the percentile of the body mass index. Hispanic Americans were more likely to be overweight (P<0.01). Nonoverweight children were more likely to participate in after-school activities, less likely to have sedentary behavior, more likely to miss school, to be more active, and had more of flourishing than their counterpart (P<0.01). Parent's marital and health status also positively affect children's obesity status (P<0.01). Social capital and neighbor amenities significantly affect children's weight status (P<0.01). A multifaceted understanding of the role of family, school, and community (with proving children's flourishing environment) in terms of how and what could contribute to children's obesity status is important in order to bring about positive impact.
