Mindfulness-based therapy for insomnia in Black women: a pilot randomized controlled trial.

The purpose of the study was to evaluate the feasibility, acceptability, and preliminary efficacy of mindfulness-based therapy for insomnia (MBT-I) among Black women. The MBT-I group received weekly sessions that included mindfulness meditation and behavioral sleep strategies. The time and attention control group received lifestyle health education (HE) that included healthy eating, physical activity, and sleep hygiene. The primary outcome was post-intervention changes in insomnia severity score by the Insomnia Severity Index (ISI) at week 10. Other measures included: Pittsburgh Sleep Quality Index, Sleep Hygiene Practice, Spielberger State-Trait Anxiety Inventory (STAI), and Patient Health Questionnaire-9 (PHQ-9). Objective sleep was measured by Actiwatch™ at baseline and week 10. Thirty Black women completed the interventions with no attrition. About 97% of all participants attended 6-8 out of 8 sessions. The ISI scores were reduced at week 10 (MBT-I vs. HE: -7.67 vs. -7.22, p < .05). Anxiety and depression symptoms were significantly improved only in the MBT-I group. This is the first MBT-I for Black women with insomnia. Online MBT-I may be feasible and acceptable for Black women. The MBT-I and HE showed a clinically significant improvement in insomnia symptoms (ISI reduction > 7). MBT-I may be more effective in improving anxiety and depression symptoms than HE. Our findings encourage further study efforts with a longer follow-up and larger sample size to address sleep health disparities among Black women.

Study Recruitment, Retention, and Adherence Among Chinese American Immigrants During the COVID-19 Pandemic.

BACKGROUND: Chinese American immigrants have been underrepresented in health research partly due to challenges in recruitment. OBJECTIVES: This study aims to describe recruitment and retention strategies and report adherence in a 7-day observational physical activity study of Chinese American immigrants with prior gestational diabetes during the COVID-19 pandemic. METHODS: Foreign-born Chinese women aged 18-45 years, with a gestational diabetes index pregnancy of 0.5-5 years, who were not pregnant and had no current diabetes diagnosis were recruited. They wore an accelerometer for 7 consecutive days and completed an online survey. Multiple recruitment strategies were used: (a) culturally and linguistically tailored flyers, (b) social media platforms (e.g., WeChat [a popular Chinese platform] and Facebook), (c) near-peer recruitment and snowball sampling, and (d) a study website. Retention strategies included flexible scheduling and accommodation, rapid communications, and incentives. Adherence strategies included a paper diary and/or automated daily text reminders with a daily log for device wearing, daily email reminders for the online survey, close monitoring, and timely problem-solving. RESULTS: Participants were recruited from 17 states; 108 were enrolled from August 2020 to August 2021. There were 2,479 visits to the study webpage, 194 screening entries, and 149 inquiries about the study. Their mean age was 34.3 years, and the mean length of U.S. stay was 9.2 years. Despite community outreach, participants were mainly recruited from social media (e.g., WeChat). The majority were recruited via near-peer recruitment and snowball sampling. The retention rate was 96.3%; about 99% had valid actigraphy data, and 81.7% wore the device for 7 days. The majority of devices were successfully returned, and the majority completed the online survey on time. DISCUSSION: We demonstrated the feasibility of recruiting and retaining a geographically diverse sample of Chinese American immigrants with prior gestational diabetes during the COVID-19 pandemic. Recruiting Chinese immigrants via social media (e.g., WeChat) is a viable approach. Nonetheless, more inclusive recruitment strategies are needed to ensure broad representation from diverse socioeconomic groups of immigrants.

Personal and Social-Built Environmental Factors of Glucose Variability Among Multiethnic Groups of Adults With Type 2 Diabetes: Research Protocol Using Ecological Momentary Assessment, Continuous Glucose Monitoring, and Actigraphy.

Glucose variability (GV)-the degree of fluctuation in glucose levels over a certain period of time-is emerging as an important parameter of dynamic glycemic control. Repeated glycemic oscillations have been reported to be the link to diabetes complications. This prospective observational study aims to: (1) identify multilevel risk factors (personal and social-built environmental factors) associated with high GV; (2) identify "within-person predictors" of high GV leveraging the intra-person data to inform future personalized diabetes interventions; and (3) examine which lifestyle factors either mediate or moderate the relationship between emotional well-being and GV among diverse adults with type 2 diabetes (T2D). We will recruit 200 adults with T2D from the community. All participants will complete baseline surveys assessing demographics, lifestyle, social-built environmental, and clinical factors. Real-time dynamic glucose levels will be measured using continuous glucose monitoring (CGM). Sleep, physical activity, diet/eating, and emotional well-being will be measured with an actigraphy device and a real-time self-report tool (ecological momentary assessment [EMA]) across 14 days. Two 24-h dietary recall data will be collected by online video calls. Generalized linear models, multilevel models, and structural equation models will be developed to achieve the study aims. The findings from the study will identify high-risk groups of high GV who would benefit from CGM to improve diabetes outcomes and inform the future development of personalized just-in-time interventions targeting lifestyle behaviors with an increased understanding of GV and by supporting healthcare providers' clinical decisions.

Factors affecting unusual postoperative vertical downward movement of mandible after surgery-first approach using intraoral vertical ramus osteotomy.

BACKGROUND: In very rare cases, patients who have undergone surgery-first approach with intraoral vertical ramus osteotomy (IVRO) exhibit unusual downward movements of mandible even up to 1-year post surgery, which makes it difficult for orthodontists to stabilize the occlusion during the postoperative orthodontic period. The aim of this study was to identify factors affecting the unusual downward movement of the mandible 1-year after the surgery-first approach using IVRO, while focusing on cephalometric values. METHODS: This retrospective cohort study sample was divided into two groups based on the amount of vertical movement of the B-point 1-year post surgery (Group S, predictable upward movement; Group U, unpredictable downward movement greater than 2 mm). To evaluate cephalometric changes between the two groups, cephalograms were obtained before surgery, 1 day after surgery, 1 month after surgery, and 1 year after surgery. The data were analyzed using the independent t-test, Mann-Whitney U test with Bonferroni correction, Pearson correlation analysis, and multiple regression analysis. RESULTS: At the initial examination, Group U showed a shallower anterior overbite. The vertical surgical change in the B-point was statistically different between the two groups (p < 0.001), indicating that group U exhibited more upward movement of the mandible during surgery. Group U showed significant downward movement of the mandible 1 month after surgery, and this finding persisted until 1 year postoperatively. Clockwise rotation of the mandible was also observed. Surgical vertical movement of the B-point showed a strong correlation with postoperative vertical movement of mandible (r = -0.674; p < 0.001) along a linear relationship, indicating that the amount of postoperative vertical downward movement of the mandible increased as the amount of surgical upward movement of the B-point increased (R2 = 0.449; p < 0.001). CONCLUSIONS: This study revealed that unusual downward movement of the mandible after a surgery-first approach using IVRO is correlated with the amount of upward movement during the surgery. When planning surgery, in cases in which a significant upward movement of the mandible is anticipated, orthodontists should prepare for the possibility of subsequent unusual downward movement and a tendency for the anterior overjet to decrease during the postoperative orthodontic period.

Using the Implementation Research Logic Model as a Lens to View Experiences of Implementing HIV Prevention and Care Interventions with Adolescent Sexual Minority Men-A Global Perspective.

Adolescents and sexual minority men (SMM) are high priority groups in the United Nations' 2021 - 2016 goals for HIV prevention and viral load suppression. Interventions aimed at optimizing HIV prevention, testing and viral load suppression for adolescents must also attend to the intersectional realities influencing key sub-populations of SMM. Consequently, there is not a robust evidence-base to guide researchers and program partners on optimal approaches to implementing interventions with adolescent SMM. Using a multiple case study design, we integrated the Implementation Research Logic Model with components of the Consolidated Framework for Implementation Research and applied it as a framework for a comparative description of ten HIV related interventions implemented across five countries (Ghana, Kenya, Nigeria, Tanzania and United States). Using self-reported qualitative survey data of project principal investigators, we identified 17 of the most influential implementation determinants as well as a range of 17 strategies that were used in 90 instances to support intervention implementation. We highlight lessons learned in the implementation research process and provide recommendations for researchers considering future HIV implementation science studies with adolescent SMM.

COVID-19 Vaccine Hesitancy Among Medicare Beneficiaries with and Without Cancer History: A US Population-based Study.

Understanding COVID-19 vaccine hesitancy among Medicare beneficiaries is critical for increasing COVID-19 vaccine uptake in the US. This study aimed to estimate and compare the vaccine hesitancy rate among community-dwelling Medicare beneficiaries with and without cancer history, also to investigate factors associated with vaccine hesitancy during the first four months after COVID-19 vaccine became available. We used population-based, cross-sectional data on 3,034 community-living Medicare beneficiaries from the Medicare Current Beneficiary Survey COVID-19 Winter 2021 Supplement. Sample weights were applied to account for the complex survey design with results generalizable to 16.4 million Medicare beneficiaries. Weighted multivariable logistic regression model was conducted to investigate the association between cancer history and vaccine hesitancy adjusting for covariates. A total of 39.6% were hesitant about getting COVID-19 vaccine. Those with cancer history were significantly less likely to be hesitant to get vaccinated than those without cancer history (adjusted odds ratio = 0.80, 95% confidence interval: 0.64, 0.99, p = .050). The most common reason for being hesitant to get COVID-19 vaccine was that the vaccine could have side effects or was viewed as not safe (19.2%), followed by not trusting what government says about vaccine (11.4%). Those with cancer history were more likely to report ongoing health conditions, lack of recommendation from a doctor, and doctor recommending against COVID-19 vaccination as reasons for not getting the vaccine compared to participants without cancer history. Increasing the confidence and knowledge about vaccine benefits among high-risk and more hesitant individuals are urgently needed to increase the vaccine uptake.

Estimation of Shape Error with Monitoring Signals.

Recently, extensive research has actively been conducted in relation to intelligent manufacturing systems. During the machining process, various factors, such as geometric errors, vibrations, and cutting force fluctuations, lead to shape errors. When a shape error exceeds the tolerance, it results in improper assembly or functionality issues in the assembled part. Predicting shape errors before or during the machining process helps increase production efficiency. In this paper, we propose a methodology that uses monitoring signals and on-machine measurement (OMM) results to predict machining quality in real time. We investigate the correlation between monitoring signals and OMM results and then construct a machine learning model for shape error estimation. The developed model implements a tool offset compensation strategy. The performance of the proposed method is evaluated under various sliding window sizes and the compensation weights. The experimental results confirmed that the proposed algorithm is effective for obtaining a uniform machining quality.

The effects of acculturation and environment on lifestyle behaviors in Korean immigrants: the mediating role of acculturative stress and body image discrepancy.

OBJECTIVES: Despite high rates of cardiometabolic diseases in Korean immigrants (KIs), little is known about cultural and environmental factors contributing to lifestyle behaviors. The purpose of this cross-sectional study was to examine the relationships among acculturation, environment, and lifestyle behaviors (dietary behavior, physical activity, and sedentary behavior) through culturally sensitive psychological mediators, body image discrepancy and acculturative stress in middle-aged KIs. DESIGN: A cross-sectional study was conducted. KIs aged 30-65 years were recruited online and at Korean community centers and churches in the Northeastern US Participants completed validated measures of dietary behavior (the Nutrition Subscale of the Health Promoting Lifestyle Profile (HPLP) II), physical activity (the International Physical Activity Questionnaire (IPAQ) - short form), and sedentary behavior (the Sedentary Behavior Questionnaire). Acculturative stress was measured by the Acculturative Stress Index and body image discrepancy was measured by the Stunkard Figure Rating Scale. Acculturation was defined as a latent variable measured by Korean and American orientation (Vancouver Index of Acculturation), age of immigration to the US, length of residency in the US, and English proficiency. Data were analyzed with structural equation modeling (SEM). RESULTS: The sample included 361 KIs (mean age = 41.77 ± 10.28 years, 48.1% female, and 46.4% overweight or obese). In the SEM model, acculturation had significant indirect effects on dietary behavior, physical activity, and sedentary behavior through body image discrepancy. Acculturative stress mediated the relationship between acculturation and sedentary behavior. Greater environmental support for physical activity and better healthy food accessibility were related to higher levels of physical activity and healthier dietary behavior, respectively. CONCLUSION: In our study, acculturation and environmental support for physical activity and healthy food simultaneously influenced KIs' lifestyle behaviors. Addressing an unhealthy body image and acculturative stress may be additional strategies for lifestyle intervention programs to prevent cardiometabolic diseases in KIs.

Differences in employment, job characteristics, and work-related perceptions by sociodemographic factors among registered nurses of diverse race/ethnicity.

BACKGROUND: Available research on registered nurses (RNs) indicates that RNs with diverse race/ethnicity are more likely to work in disadvantaged workplaces. PURPOSE: To examine differences in employment, job characteristics and perceptions about work among RNs by sociodemographic characteristics. METHODS: We analyzed data from statewide random samples of California RNs (N=895). FINDINGS: Increased age was associated with increased likelihoods of working part-time, day-shift, and in non-hospital settings and having managerial positions. Asian and Black nurses were more likely to work in urban areas than White nurses. The levels of job demand, job control, job satisfaction, perceived organizational culture, and safety climate were significantly different by sociodemographic characteristics. Greater intention to leave the job was associated with younger age and working in non-hospital settings. DISCUSSION: The findings suggest that differences exist in nurses' employment, job characteristics, and perceptions about their work and work environment by sociodemographic characteristics among RNs of diverse race/ethnicity.

Reflections on obesity-related health behaviors over time and suggestions for health promotion programs from African American women.

African American (AA) women have the highest rate of obesity in the United States. To date, there are mixed findings on AA women's perception on obesity and their perceived changes in health behaviors over time that may have contributed to obesity. Therefore, the aims of this current qualitative descriptive study were to explore: 1) AA women's perception on obesity and perceived changes in health behaviors related to obesity through their reflection on life; 2) AA women's perceived facilitators and barriers to maintaining healthy behaviors; and 3) AA women's suggestions for future health promotion programs to manage obesity. Semi-structured interviews with ended questions were conducted with 21 AA women. Luborsky's method for thematic analysis was used to analyze data. Three main themes with subthemes were identified. First main theme was the AA culture that served as a facilitator and barrier to maintaining healthy lifestyle from childhood to young adulthood. Second main theme was gradual changes in their healthy lifestyle due to social and physical environment from young adulthood to middle adulthood. Third main theme was AA women's various suggestions for future health promotion programs. This study found obesity to be a multifactorial phenomenon that is a result of complex interaction of culture, environment, and social networks. Therefore, clinicians need to address the issue of obesity from a holistic perspective for AA women to actively engage with their primary health care. Future health promotion programs should incorporate culturally tailored lifestyle components and increase knowledge on healthy lifestyle against obesity through community-based programs.

Mediating roles of psychological factors and physical and social environments between socioeconomic status and dietary behaviors among African Americans with overweight or obesity.

The study aim was to examine the relationship between socioeconomic status (SES) and dietary behaviors through psychological and environmental mediators among African Americans with overweight or obesity. We conducted a cross-sectional study in 225 African American men and women. Data were analyzed using structural equation modeling with bootstrapping procedures. In the multiple mediation model, SES had a significant indirect effect on dietary behaviors through psychological and environmental factors (ß = -.27; p = .01; 95% confidence interval [CI] = -0.59--0.10), but it had no significant direct effect on dietary behaviors (ß = .06; p = .70; 95% CI = -0.21-0.39). SES had significant direct effects on psychological (ß = .52; p = .01; 95% CI = 0.31-0.77) and environmental factors (ß = -.40; p = .03; 95% CI = -0.53--0.25). Psychological (ß = -.31; p = .02; 95% CI = -0.68--0.04) and environmental factors (ß = .26; p = .01; 95% CI = 0.04-0.47) also showed significant direct effects on dietary behaviors. Thus, psychological and environmental factors mediated the relationship between SES and dietary behaviors in African Americans with overweight or obesity. Interventions that enhance psychological and environmental factors such as self-efficacy, perceived barriers to healthy eating, health perceptions, and physical and social environments may improve dietary behaviors among socioeconomically disadvantaged African Americans.

Feasibility and acceptability of intensive, real-time biobehavioral data collection using ecological momentary assessment, salivary biomarkers, and accelerometers among middle-aged African Americans.

Perceived racial discrimination is linked to unhealthy behaviors and stress-related morbidities. A compelling body of research indicates that perceived racial discrimination may contribute to health disparities among African Americans (AAs). The purposes of this study were to describe the study protocol including data collection procedures and study measures and to evaluate the feasibility and acceptability of intensive biobehavioral data collection using ecological momentary assessment (EMA), salivary biomarkers, and accelerometers over 7 days among middle-aged AAs with a goal of understanding the relationships between perceived racial discrimination and biobehavioral responses to stress. Twelve AA men and women participated in the feasibility/acceptability study. They completed surveys, anthropometrics, and received in-person training in EMA and saliva sample collection at baseline. Participants were asked to respond to the random prompt text message-based EMA five times a day, wear an accelerometer daily for 7 days, and to self-collect saliva samples four times a day for 4 consecutive days. The EMA surveys included perceived racial discrimination, affective states, lifestyle behaviors, and social and physical contexts. The mean EMA response rate was 82.8%. All participants collected saliva samples four times a day for 4 consecutive days. About 83% of participants wore the accelerometer on the hip 6 out of 7 days. Despite the perception that the intensive nature of assessments would result in high participant burden, the acceptability of the study procedures was uniformly favorable.

Social Network Structures in African American Churches: Implications for Health Promotion Programs.

The prevalence of obesity among African Americans is higher than among other racial/ethnic groups. African American churches hold a central role in promoting health in the community; yet, church-based interventions have had limited impact on obesity. While recent studies have described the influence of social networks on health behaviors, obesity interventions informed by social network analysis have been limited. We conducted a cross-sectional study with 281 African American men and women from three churches in northeast urban cities in the USA. Data were collected on sociodemographic and clinical factors and anthropometrics. Using a social network survey applying a name generator, we computed network level metrics. Exponential random graph models (ERGM) were performed to examine whether each structural property found in the empirical (observed) networks occurred more frequently than expected by chance by comparing the empirical networks to the randomly simulated networks. Overall, church friendship networks were sparse (low density). We also found that while friendship ties were more reciprocated between dyads in church networks, and there were more tendencies for clustering of friendships (significant positive transitive closure) than in random networks, other characteristics such as expansiveness (number of actors with a great number of friends) did not differ from what would be expected by chance in random networks. These data suggest that interventions with African American churches should not assume a unitary network through which a single intervention should be used.

Obesity-risk behaviours and their associations with body mass index (BMI) in Korean American children.

AIMS AND OBJECTIVES: To describe obesity-risk behaviours (diet, physical activity and sedentary behaviour) and examine the relationships of the obesity-risk behaviours with body mass index (BMI) in school-aged Korean American children. BACKGROUND: Korean American children have a risk of becoming overweight or obese and developing obesity-related complications; however, there is limited research about obesity-risk behaviours in Korean American children. DESIGN: A cross-sectional study. METHODS: Obesity-risk behaviours of children were assessed with well-validated self-report questionnaires (i.e., Elementary-level School-based Nutrition Monitoring Questionnaire) from children and their mothers. Height and weight of children were measured. Data were analysed with bivariate and multivariate analyses using mixed effects models to incorporate the correlation within siblings. RESULTS: A total of 170 Korean American children (mean age 10.9 [2.0] years; 52.4% girls; mean BMI 19.3 [3.2]; 28.7% ≥85 percentiles) participated in the study. Only 38.3% of Korean American children met established recommendations of five fruits/vegetables per day; 56.5% met recommendations for more than 3 days per week of vigorous physical activity; and 40.8% met recommendations for <2 hr of recreational screen time per day. Sixty per cent and 88.8% of children met the recommendation of sleep on a weekday and weekend, respectively. Only screen time was positively associated with child BMI z-score (ß = 0.08; p < .03). CONCLUSION: Healthcare providers need to be aware of the increased rate of overweight and obesity in Korean American children and initiate clinical interventions to improve obesity-risk behaviours, especially sedentary behaviour, in Korean American children. RELEVANCE TO CLINICAL PRACTICE: Clinical assessment and management of the risk of developing overweight and obesity as well as obesity-related behaviours are important to improve obesity-related complications in overall Korean Americans.

Lifestyle interventions based on the diabetes prevention program delivered via eHealth: A systematic review and meta-analysis.

The objective was to describe Diabetes Prevention Program (DPP)-based lifestyle interventions delivered via electronic, mobile, and certain types of telehealth (eHealth) and estimate the magnitude of the effect on weight loss. A systematic review was conducted. PubMed and EMBASE were searched for studies published between January 2003 and February 2016 that met inclusion and exclusion criteria. An overall estimate of the effect on mean percentage weight loss across all the interventions was initially conducted. A stratified meta-analysis was also conducted to determine estimates of the effect across the interventions classified according to whether behavioral support by counselors post-baseline was not provided, provided remotely with communication technology, or face-to-face. Twenty-two studies met the inclusion/exclusion criteria, in which 26 interventions were evaluated. Samples were primarily white and college educated. Interventions included Web-based applications, mobile phone applications, text messages, DVDs, interactive voice response telephone calls, telehealth video conferencing, and video on-demand programing. Nine interventions were stand-alone, delivered post-baseline exclusively via eHealth. Seventeen interventions included additional behavioral support provided by counselors post-baseline remotely with communication technology or face-to-face. The estimated overall effect on mean percentage weight loss from baseline to up to 15months of follow-up across all the interventions was -3.98%. The subtotal estimate across the stand-alone eHealth interventions (-3.34%) was less than the estimate across interventions with behavioral support given by a counselor remotely (-4.31%), and the estimate across interventions with behavioral support given by a counselor in-person (-4.65%). There is promising evidence of the efficacy of DPP-based eHealth interventions on weight loss. Further studies are needed particularly in racially and ethnically diverse populations with limited levels of educational attainment. Future research should also focus on ways to optimize behavioral support.

Factors associated with school-aged children's body mass index in Korean American families.

AIMS: To examine factors associated with children's body mass index and obesity-risk behaviours in Korean American families. BACKGROUND: Limited data are available about family factors related to overweight and obesity in Korean American children. DESIGN: A cross-sectional study. METHODS: Convenient sampling was employed to recruit Korean American families in the Northeast of the United States between August 2014 and January 2015. Child, family and societal/demographic/community factors were measured with self-report questionnaires completed by mothers and children. Height and weight were measured to calculate body mass index. Data were analyzed using mixed effects models incorporating within-group correlation in siblings. RESULTS: The sample included 170 Korean American children and 137 mothers. In bivariate analyses, more child screen time, number of children in the household, greater parental underestimation of child's weight and children's participation in the school lunch program were significantly associated with higher child body mass index. In multivariate analyses that included variables showing significant bivariate relationship, no variable was associated with child body mass index. CONCLUSION: There were no child, family and societal/demographic/community factors related to child body mass index in Korean American families in the multivariate analysis, which is contrary to research in other racial/ethnic groups. In bivariate analyses, there is evidence that some factors were significantly related to child body mass index. Further research is needed to understand the unique behavioural, social and cultural features that contribute to childhood obesity in Korean American families.

Lifestyle Intervention for Sleep Disturbances Among Overweight or Obese Individuals.

Little is known about the effect of different lifestyle interventions on sleep disturbances among sedentary obese or overweight persons. We randomized men and women aged 35-65 to 6 months of a weight loss diet (D); or D combined with supervised exercise training D + E. Measurements were self-reported sleep disturbances, the Profile of Mood States questionnaire, BMI, total abdominal subcutaneous and visceral fat by magnetic resonance imaging, and aerobic fitness expressed as VO2peak. The groups did not differ in changes for body weight, abdominal total fat, VO2peak, and sleep disturbances. The novel finding herein is that reduced abdominal subcutaneous fat and depressive symptoms, with either D or D + E were associated with less sleep disturbances.

Social networks and future direction for obesity research: A scoping review.

Despite significant efforts to decrease obesity rates, the prevalence of obesity continues to increase in the United States. Obesity risk behaviors including physical inactivity, unhealthy eating, and sleep deprivation are intertwined during daily life and are difficult to improve in the current social environment. Studies show that social networks-the thick webs of social relations and interactions-influence various health outcomes, such as HIV risk behaviors, alcohol consumption, smoking, depression, and cardiovascular mortality; however, there is limited information on the influences of social networks on obesity and obesity risk behaviors. Given the complexities of the biobehavioral pathology of obesity and the lack of clear evidence of effectiveness and sustainability of existing interventions that are usually focused on an individual approach, targeting change in an individual's health behaviors or attitude may not take sociocontextual factors into account; there is a pressing need for a new perspective on this problem. In this review, we evaluate the literature on social networks as a potential approach for obesity prevention and treatment (i.e., how social networks affect various health outcomes), present two major social network data analyses (i.e., egocentric and sociometric analysis), and discuss implications and the future direction for obesity research using social networks.

Weight status, gender, and race/ethnicity: are there differences in meeting recommended health behavior guidelines for adolescents?

Healthy behaviors including limited screen time (ST), high physical activity (PA), and adequate fruits and vegetables consumption (FV) are recommended for adolescents, but it is unclear how gender, race/ethnicity, and weight status relate to these public health guidelines in diverse urban adolescents. Participants (N = 384) were recruited from three public high schools in or near New Haven, Connecticut. Descriptive statistics and logistic regression analyses were conducted. Most adolescents exceeded recommended levels of ST (70.5%) and did not meet guidelines for PA (87.2%) and FV (72.6%). Only 3.5% of the sample met all three guidelines. Boys were more likely to meet guidelines for PA (p < .01), while girls were engaged in less ST (p < .001). Black, non-Latinos were less likely to meet PA guidelines (p < .05). There were no significant differences in meeting ST, PA, or FV guidelines by weight status for the overall sample or when stratified by gender or race/ethnicity. We found alarmingly low levels of healthy behaviors in normal weight and overweight/obese adolescents.
