Socio-Cultural and Environmental Factors that Influence Weight-Related Behaviors: Focus Group Results from African-American Girls and Their Mothers

Adolescent Development in Context: A Decade Review of Neighborhood and Activity Space Research

Over the last decade, two lines of inquiry have emerged from earlier investigations of adolescent neighborhood effects. First, researchers began incorporating space-time geography to study adolescent development within activity spaces or routine activity locations and settings. Second, cultural-developmental researchers implicated neighborhood settings in cultural development, to capture neighborhood effects on competencies and processes that are salient or normative for minoritized youth. We review the decade's studies on adolescent externalizing, internalizing, academic achievement, health, and cultural development within neighborhoods and activity spaces. We offer recommendations supporting decompartmentalization of cultural-developmental and activity space scholarship to advance the science of adolescent development in context.

A decision-support approach under uncertainty for evaluating reverse logistics capabilities of healthcare providers in Iran

Purpose

This paper aims to assess and prioritize manufacturing companies in the healthcare industry based on critical success factors (CSFs) of their reverse logistics (RL). The research involves seven medical device companies located in the Tehran Province, Iran.

Design/methodology/approach

To identify and prioritize companies based on CSFs of RL, the study proposes a three-phase decision-making framework that integrates the Delphi method, the best-worst method (BWM) and the Additive Ratio Assessment (ARAS) method with Z-numbers. The weights required for this method are obtained by a variant of the BWM based on Z-numbers, denoted as Z-numbers Best-Worst Method, or ZBWM. Since decision-makers face an uncertain environment, Z-numbers, which are a kind of fuzzy numbers, are applied.

Findings

First, after customizing CSFs by the Delphi method and obtaining 15 CSFs of RL, these are ranked by the hybrid BWM-ARAS method with Z-numbers. Results reveal which company appears to perform best with respect to their RL implementations. Based on this result, healthcare device companies should choose the highest priority company based on the selected RL CSFs and results from using the BWM-ARAS method with Z-numbers.

Originality/value

The contribution of this paper is using a hybrid ARAS-BWM method based on Z-numbers. Each of these methods has some merits compared to other similar methods. The combination of these methods contributes a new approach for prioritizing companies based on RL CSFs with high accuracy and reliability.

Psychosociocultural Contributors to Maladaptive Eating Behaviors in African American Youth: Recommendations and Future Directions

Childhood overweight and obesity disproportionately affects African Americans, and these children benefit less from standard pediatric weight management treatment programs compared to other racial/ethnic groups. Maladaptive eating behavior has been identified as a behavioral contributor to obesity and is also associated with the development of nonrestrictive eating disorders over time. Unique psychosociocultural factors have been identified that may promote higher risk for maladaptive eating behaviors in African American children beyond the effects of economic disparity. To best treat this group, it is important for practitioners to have a thorough understanding of these factors. We review several of these considerations and describe ways they may interact to contribute to the subsequent development of maladaptive eating behaviors and increased weight. Recommendations are made regarding how attention to these factors could be incorporated into current pediatric weight management treatments to better serve this population via a patient-centered care approach. Future directions will also be discussed.

Using photovoice to explore social determinants of obesity in two underserved communities in the southeast

Over the past 25 years, the adult obesity rate in the U.S. has increased 70%, with obesity placing a disproportionate chronic disease burden on African Americans. Using Photovoice methodology, this study aimed to: (1) explore the social determinants contributing to obesity from the perspectives of residents of two low-income municipalities in Birmingham, Alabama with varying levels of segregation, (2) better understand residents' perceptions of contributors to obesity in their communities, and (3) examine residents' perceptions of interventions that might be effective in promoting positive change. Focus groups (N=10) segmented by race and community were conducted by trained moderators. Transcriptions were analyzed by theoretical thematic analysis. The study design and data analysis analyses were guided by a conceptual framework based on the Social Determinants of Obesity model. Findings from this study lend support to the efficacy of the conceptual framework as a multilevel approach describing obesity disparities in the south. Regardless of community and race, participants believed that elements of their built environment, such as fast food restaurants and unsafe walking conditions, contributed to obesity, and that schools and churches should play an active role in addressing the issue.

Development and feasibility of a brief Zero-time Exercise intervention to reduce sedentary behaviour and enhance physical activity: A pilot trial

A brief intervention using Zero-time Exercise (ZTEx), a foot-in-the-door approach, was developed to reduce sedentary behaviour and increase physical activity. ZTEx refers to the integration of simple strength- and stamina-enhancing physical activity into daily life, which can be done anytime, anywhere and by anyone. This paper presents the development, feasibility, and preliminary evidence for the effectiveness of this intervention under the Hong Kong Jockey Club FAMILY Project. Needs assessments were conducted with social workers from the Christian Family Services Center(CFSC) and the Social Welfare Department (SWD). This single group prospective ZTEx intervention trial, guided by the Health Action Process Approach, included a 3-hr core session at baseline and a 1-hr booster session at 1-month follow-up. Fifty-six participants (social and service-related workers) from CFSC (n = 28) and SWD (n = 28) received the intervention and completed the self-administered questionnaires at baseline. Forty-nine and 43 participants completed the 1-month and 3-month self-administered questionnaires, respectively. Fifteen participants attended the focus group interviews to share their feedback on ZTEx intervention after implementing their community-based ZTEx activities. Intention-to-treat analysis was conducted with missing data replaced by baseline values. Participants reported significant decreases in sitting time by 27 (2, 52) minutes (mean [95% confidence interval]) and 36 (0.2, 71) minutes on a weekday, increases in physical activity while seated by 0.7 (0.2, 1.4) days and 1.1 (0.6, 1.7) days in a week, and improvements in perceived knowledge, outcome expectancies and plan on doing ZTEx at the 1-month and 3-month follow-up, respectively. Balance and muscle strength significantly improved at the 1-month follow-up. The effect ranged from small to large (Cohen's d: 0.27-1.05, all p < 0.05). The qualitative feedbacks support the quantitative findings. Our findings show early evidence that ZTEx effectively reduced sedentary behaviour and enhanced physical activity and fitness. Further trials on this simple and low-cost intervention as the first step to promote higher intensity exercise are warranted.
