RESUMEN
OBJECTIVES: The primary objective of this study is to further explore associations between social influencers of health and markers of disease severity at the time of presentation of patients with pediatric metabolic dysfunction-associated steatotic liver disease (MASLD) using neighborhood-level Area Deprivation Index (ADI) scores. METHODS: A retrospective cross-sectional study was conducted among 344 pediatric MASLD patients. Each patient received an ADI score based on their 9-digit zip code. Groups were defined as low (≤5) and high (6≥) ADI. Associations between ADI and symptomatology and laboratory values at presentation, as well as initial liver biopsy pathology were tested via analyses of covariance, χ2 testing, and logistic regressions. RESULTS: The mean ADI was 6.54 (standard deviation = 2.09). ADI groups did not significantly differ in age of presentation, type of presentation, or associated conditions, except for the higher ADI group having on average lower vitamin D levels (26.70 vs. 29.91, p = 0.02) and being two times more likely to also be diagnosed with low high-density lipoprotein (HDL) levels (p = 0.04, 95% CI 1.04-3.89). Mean transaminases and histopathologic nonalcoholic fatty liver disease (NAFLD) Activity Scores did not significantly differ between ADI groups. CONCLUSIONS: Pediatric patients with MASLD in this study span the entire spectrum of neighborhood deprivation. There were no differences in presentation characteristics or severity of MASLD, aside from lower HDL-cholesterol and vitamin D values in the high ADI group. Area deprivation was not predictive of more severe disease as assessed by serum transaminases and liver biopsy NAFLD activity scores.

BACKGROUND: Cervical and other vaccine-preventable HPV-associated cancers disproportionately impact Hispanic/Latinos in the USA. HPV vaccine uptake may be impacted by community agreement with common HPV vaccine misperceptions. It is unknown whether Hispanics/Latinos have a greater agreement with these misperceptions relative to non-Hispanic whites. METHODS: HPV vaccine misperceptions were assessed through a 12-item Likert scale included in a population health assessment mailed to households in the southwest United States. Linear regression models assessed the association between identifying as Hispanic/Latino and summed misperception score. RESULTS: Among the 407 individuals in the analytic sample, 111 (27.3%) were Hispanic/Latino and 296 (72.7%) were non-Hispanic white. On average, Hispanics/Latinos had a 3.03-point higher HPV vaccine misperception sum score relative to non-Hispanic whites, indicating greater agreement with misperceptions (95% confidence interval: 1.16-4.88; p < 0.01). DISCUSSION: Culturally relevant interventions are needed to address HPV vaccine misperceptions among Hispanics/Latinos as part of efforts toward HPV-associated cancer health equity.
RESUMEN
BACKGROUND: Monoclonal antibody (mAb) treatment for COVID-19 is associated with improved clinical outcomes. However, there is limited information regarding the impact of treatment on symptoms and the prevalence of post-COVID Conditions (PCC). Understanding of the association between time to mAb infusion and the development of PCC is also limited. METHODS: This longitudinal study was conducted among patients with COVID-19 who received mAb infusions at a Federally Qualified Health Center in San Diego, CA. A series of telephone interviews were conducted at baseline and follow-up (14 days and 28+ days). A comprehensive symptom inventory was completed and physical and mental health status were measured using PROMIS-29 and PHQ-2. Pearson's Chi-squared tests and independent two-sample t-tests were performed to test for association between time to mAb infusion and outcomes at follow-up. A Poisson regression model was used to analyze whether time to mAb infusion predicts risk of developing PCC. RESULTS: Participants (N = 411) were 53% female, ranged in age from 16 to 92 years (mean 50), and a majority (56%) were Latino/Hispanic. Cross-sectional findings revealed a high symptom burden at baseline (70% of patients had cough, 50% had fever, and 44% had headache). The prevalence of many symptoms decreased substantially by the final follow-up survey (29% of patients had cough, 3% had fever, and 28% had headache). Longitudinal findings indicated that 10 symptoms decreased in prevalence from baseline to final follow-up, 2 remained the same, and 14 increased. The severity of symptoms and most patient-reported physical and mental health measure scores decreased over time. The prevalence of PCC was 69% when PCC was defined as ≥ 1 symptom at final follow-up. Time to mAb infusion was not significantly associated with any outcome at follow-up. Time to infusion was not associated with PCC status at final follow-up in the crude or adjusted Poisson regression models. CONCLUSIONS: The prevalence of PCC was high among this patient population following COVID-19 mAb treatment. Time to mAb infusion did not predict the development of PCC. Further research in these areas is essential to answer urgent clinical questions about effective treatments of COVID-19.

INTRODUCTION: Removal of tobacco industry branding from cigarette packs may reduce their appeal. Adding graphic warning labels (GWLs) should enhance this effect. We investigate whether willingness to pay for various packaging designs changes after 3 months' use of: (1) US branded packs without GWLs (US), (2) non-branded packs without GWLs (Blank), and (3) rotating non-branded packs with GWLs (gangrene; throat cancer; neonatal baby) covering >75% of pack (GWL). METHODS: Californian adult daily smokers not planning to quit (n=287; 56% female; mean age=39.6) completed a discrete choice purchase task before and after 3 months' experience using one of three packaging options. Conjoint analysis and pre-post modelling evaluated the change in importance of pack attributes and willingness to pay for US, Blank or GWL (blindness; teeth; gangrene) pack designs. RESULTS: Price determined ~70% of purchase choices, while pack design determined ~22%. Irrespective of intervention arm, US packaging generated appeal valuations compared with Blank packaging, while GWLs consistently provoked strong aversive valuations at baseline and follow-up. Compared with the US pack arm, using GWL packs for 3 months decreased willingness to pay for US packaging (ß=-$0.38, 95% CI -0.76 to 0.00). Wear-out effects were detected in the discount needed to willingly purchase the gangrene-GWL pack (ß=$0.49, 95% CI 0.16 to 0.82) and Blank pack (ß=$0.42, 95% CI 0.09 to 0.74) but not for GWLs (blindness, teeth) not used in trial. CONCLUSION: Compared with US branded packs, the negative valuation of non-branded GWL packs attenuates with even 3 months' use but does not generalise to non-used GWLs. This suggests that GWLs should be regularly refreshed. The appeal valuation of industry imagery suggests that the US plan to retain such imagery on packs may ameliorate the effect of GWLs.

Purpose: Human papillomavirus (HPV)-related oral cancers are increasing, and lesbian, gay, bisexual, and other people with a minority sexual orientation may be disproportionately impacted. This study examined the relationship between sexual orientation and HPV-related oral cancer knowledge. Methods: Data from 10,859 adult participants in the 2017-2019 Health Information National Trends Survey 5, cycles 1-3, were obtained. The three data sets were merged, and weighted multiple imputation (n = 15) was applied to address missingness. Weighted logistic regression analyses examined differences in HPV-related oral cancer knowledge between sexual minority versus heterosexual participants by sex, after adjustment for race, ethnicity, age, education, income, insurance, regular medical provider, and smoking status. Results: In this weighted sample, age ranged from 18 to 101 years (mean = 56.3 years); 42% were males, 5.2% were sexual minority men/women, and 94.8% were heterosexual/straight. Overall, only 19% of respondents were aware that HPV can cause oral cancer. After controlling for sociodemographic factors, there were no significant differences in HPV-related oral cancer knowledge for sexual minority men (adjusted odds ratio [AOR]: 1.10; 95% confidence interval [95% CI]: 0.86-1.42) or women (AOR: 0.98; 95% CI: 0.76-1.26) compared with those who were heterosexual/straight. Conclusion: Overall, knowledge of HPV-related oral cancer was low, regardless of sexual orientation. There were no differences in HPV-related oral cancer knowledge between sexual minority men and women compared with their heterosexual counterparts. Educational programs are needed to increase awareness of the HPV/oral cancer link. Further research on differences in HPV-related oral cancer knowledge and attitudes by sexual orientation and the intersection of other demographic factors is warranted.

OBJECTIVE: To identify whether three types of cigarette pack designs, including three versions of graphic warning label (GWL) plain packs, one GWL absent and branding absent pack (blank) and the smoker's own GWL absent and branding present pack (US), elicit different valence, type and levels of affect. DESIGN: US daily smokers (n=324) were asked to handle each of the five pack types and 'think aloud' their reactions. To avoid a muted familiarity response, exposure to their own US pack followed exposure to at least one GWL plain pack. Reactions were scored on a reactivity scale (-3 to +3) and the text was coded for speech polarity (-1 to +1) and emotive word frequency. RESULTS: Reactivity scores had excellent inter-rater reliability (agreement ≥86%; intraclass correlation coefficient ≥0.89) and were correlated with speech polarity (r=0.21-0.37, p<0.001). When considering their US pack, approximately two-thirds of smokers had a low (31.5%) to medium (34.6%) positive response (reactivity=1.29; polarity=0.14) with expressed feelings of joy and trust. Blank packaging prompted a largely (65.4%) neutral response (reactivity=0.03; polarity=0.00). The gangrenous foot GWL provoked mostly medium (46.9%) to high (48.1%) negative responses (reactivity=-2.44; polarity=-0.20), followed by neonatal baby (reactivity=-1.85; polarity=-0.10) and throat cancer (reactivity=-1.76; polarity=-0.08) warnings. GWLs varied in their elicitation of disgust, anger, fear and sadness. CONCLUSION: Initial reactions to GWL packs, a blank pack, and smokers' current US pack reflected negative, neutral, and positive affect, respectively. Different versions of the GWL pack elicited different levels and types of immediate negative affect.

Dysmenorrhea is highly prevalent, ranging from 16% to 91% among women, and it can lead to multiple reproductive disorders. However, risk factors associated with dysmenorrhea remain unexamined. Cold exposures can significantly disturb blood circulation and prostaglandin production in the uterus, leading to dysmenorrhea. This study investigated the relationship between cold exposures and dysmenorrhea, as well as potential disparities between Asians and Whites and the potential cultural influences on these associations. This was a cross-sectional survey among 197 Asian and 222 non-Asian women recruited from the U.S., with more than 40% from California. We assessed cold exposures, such as the frequency of consumption of cold water/drinks and ice cream, as well as room temperatures at home and public places, for both summer and winter over the past 12 months. The type of cold exposure associated with dysmenorrhea differs between Asian and White women. We found that among Asian women, a higher frequency of ice cream consumption in winter (beta = 1.19, p = 0.0002 when comparing high to low categories) was associated with dysmenorrhea; however, among White women, increased consumption of cold water/drinks in winter (beta = 0.49, p = 0.04 when comparing high to low categories) was also associated with dysmenorrhea. Higher home room temperatures in winter were associated with reduced severity of dysmenorrhea among White women but not among Asian women. All these associations supported our hypothesis and were stronger among women who lived in states with colder winters. However, there are a few exceptions. For instance, women who drank cold water/drinks less frequently during their menstrual period were more likely to experience more severe dysmenorrhea. In conclusion, this study provides crucial evidence to support the link between cold exposures and dysmenorrhea among Asians and Whites. The associations contradictory to our hypothesis are likely due to reserved causation influenced by Asian cultural practice. This paper sheds light on an understudied area that profoundly affects women's quality of life.

Introduction: Few studies have focused on physical activity (PA) maintenance, particularly among minority populations; smartphone apps could provide valuable tools. This study aimed to 1) assess and understand PA maintenance among Latinas who completed a PA intervention; and 2) evaluate the feasibility, acceptability and preliminary efficacy of commercial smartphone apps as tools for PA maintenance. Methods: For this feasibility study, 27 Latinas who completed a PA intervention and increased their PA were randomly assigned to enhanced maintenance (i.e., taught to use commercial smartphone apps, N=14), or regular maintenance (i.e., no additional treatment, N=13). After 3-months, the feasibility and acceptability of using apps for PA maintenance was assessed via survey questions, analyzed using descriptive statistics. PA was reassessed via the 7-day PA Recall and analyzed using longitudinal mixed effects regression models. Qualitative data were collected via open-ended interview questions and analyzed using thematic analysis. Results: 43% of enhanced maintenance participants reported using study apps at least "a little" and 21% using them "a lot." Although not statistically significant, enhanced maintenance participants reported a smaller drop in PA from post-intervention to post-maintenance, compared to regular maintenance participants. Several participants expressed approval of the apps, while others reported on factors that kept them from using the apps for PA maintenance. Conclusion: Incorporating lessons learned from this study, larger randomized trials are warranted to evaluate the efficacy of using smartphone apps to support PA maintenance. The widespread use of apps could make them ideal tools to support PA maintenance after interventions in different settings.
RESUMEN
The ongoing 2019 novel coronavirus disease (COVID-19) pandemic continues to impact the health of individuals worldwide, including causing pauses in lifesaving cancer screening and prevention measures. From time to time, elective medical procedures, such as those used for cancer screening and early detection, were deferred due to concerns regarding the spread of the infection. The short- and long-term consequences of these temporary measures are concerning, particularly for medically underserved populations, who already experience inequities and disparities related to timely cancer care. Clearly, the way out of this pandemic is by increasing COVID-19 vaccination rates and doing so in an equitable manner so that communities most affected receive preferential access and administration. In this article, we provide a perspective on vaccine equity by featuring the experience of the California Hispanic community, who has been disproportionately impacted by the pandemic. We first compared vaccination rates in two United States-Mexico border counties in California (San Diego County and Imperial County) to counties elsewhere in California with a similar Hispanic population size. We show that the border counties have substantially lower unvaccinated proportions of Hispanics compared to other counties. We next looked at county vaccination rates according to the California Healthy Places Index, a health equity metric and found that San Diego and Imperial counties achieved more equitable access and distribution than the rest of the state. Finally, we detail strategies implemented to achieve high and equitable vaccination in this border region, including Imperial County, an agricultural region that was California's epicenter of the COVID-19 crisis at the height of the pandemic. These United States-Mexico border county data show that equitable vaccine access and delivery is possible. Multiple strategies can be used to guide the delivery and access to other public health and cancer preventive services.

The goal of this paper is to determine the association between traveling to engage in sex work in another country and recent access to HIV testing among substance-using female sex workers (FSWs) in the Mexico-Guatemala border region. From 2012 to 2015, through modified time-location sampling and peer referral, 255 FSWs were recruited at Mexico's southern border. Participants completed questionnaires on sociodemographics, migration and mobility experiences, work environment factors, and substance use. A conceptual framework, as depicted by a directed acyclic graph (DAG), guided our analysis. Crude and adjusted logistic regression models were used to evaluate the relationships between mobility experiences and HIV testing in the past year. Overall HIV testing was low (41%); after considering relevant covariates (i.e., interaction with health services and organizations, and sex work characteristics) traveling to engage in sex work in another country was found to be positively associated with HIV testing in the past year. Future efforts need to consider voluntary and non-stigmatizing prevention HIV services and focus on reaching out to less mobile women.
RESUMEN: El objetivo de este artículo es determinar la asociación entre viajar a otro país para ejercer el comercio sexual y el acceso a una prueba reciente de VIH, en una población de mujeres trabajadoras sexuales en la frontera de México con Guatemala. Entre el 2012 y 2015, utilizando un muestreo por conveniencia y por referencia de pares, se invitó a 255 mujeres trabajadoras sexuales en la frontera sur de México a participar en este proyecto de investigación. Las participantes completaron una encuesta que comprendió preguntas sociodemográficas así como experiencias de migración y movilidad, características del trabajo sexual, y patrones de uso de sustancia. Utilizamos un marco conceptual que se ilustra en una Gráfica Acíclica Dirigida (DAG) el cual sirvió para guiar nuestro análisis. Realizamos análisis de regresión logística cruda y ajustada para evaluar la asociación entre experiencias de movilidad y haber recibido una prueba de VIH en el último año. En general, el porcentaje de haber recibido una prueba de VIH en el último año fue bajo (41%); después de considerar covariables relevantes; (ej., interacción con organizaciones y servicios de salud, características del trabajo sexual) encontramos que viajar a otro país para ejercer el comercio sexual está asociado con haber recibido una prueba de VIH en el último año. Es importante que, en el futuro, se concentren esfuerzos en servicios de prevención del VIH que sean voluntarios, no estigmatizantes, y que se enfoquen en mujeres trabajadoras sexuales menos móviles.

Substance use and depressive psychiatric symptoms have been associated with migration and mobility. The Mexico-Guatemala border is a key transit point for internal, regional, and international migration flows. However, there is limited knowledge of the role of substance use, migration, and mobility on mental health among migrants at this border. Our paper explores the association of migration and mobility patterns with possible major depressive symptoms among migrants at this key geographic region. We recruited 392 substance-using migrants using modified time-location sampling. Crude and adjusted logistic regression models were developed. We found that 12% of the sample had possible major depressive symptoms. After adjusting for relevant covariates, including gender, income, and perceived homelessness, we found that recent rural-urban and short-term migrants had higher odds of possible major depressive symptoms, whereas international migrants had lower odds. Findings of this paper suggest that although migrants experience hardship and uncertainty, they may respond with complex and nuanced forms of coping and planning.

BACKGROUND: The impact of physical activity interventions for Latina women can be enhanced by identifying and implementing strategies to achieve long-term physical activity maintenance. Physical activity promotion research has mainly focused on physical activity initiation and we know little regarding individual, interpersonal, or environmental factors that influence maintenance of physical activity. This study aimed to qualitatively explore and understand factors associated with maintenance and non-maintenance of physical activity among Latinas. METHODS: Semi-structured individual interviews were conducted with 21 Latinas who increased their physical activity as a result of an intervention, and who completed a 3-month maintenance period without contact from research staff. Data were analyzed using thematic analysis. RESULTS: Important facilitators of physical activity maintenance described by participants included having made physical activity a habit; the ability to proactively overcome obstacles to engaging in physical activity, and satisfaction with outcomes obtained from engaging in physical activity. Additional facilitators mentioned by both maintainers and non-maintainers included having motivation, social support, and opportunities to be active. Both maintainers and non-maintainers reported high self-efficacy for PA maintenance in the future. CONCLUSIONS: Guiding intervention participants to form habits and to set realistic expectations could help them to independently continue engaging in physical activity upon completion of physical activity interventions. Teaching them skills to proactively overcome obstacles may also be important for physical activity maintenance.

BACKGROUND: Performing regular muscle-strengthening activity has numerous health benefits, including improvements in blood pressure, hemoglobin A1c, and lean body mass. Despite the disproportionate prevalence of lifestyle-related chronic disease in Latinas (diabetes, hypertension, obesity), most do not report meeting the national guidelines for muscle-strengthening activity. Existing physical activity (PA) research in Latinas has focused almost exclusively on aerobic PA. Our study examined Latinas' sociodemographic and psychosocial correlates of meeting muscle-strengthening PA guidelines that can inform future PA interventions. METHOD: A cross-sectional study of participants (N = 436) enrolled in a randomized controlled trial promoting PA and cancer screening in Latinas was conducted, and t tests examined the associations between sociodemographic and psychosocial factors with self-reported muscle-strengthening activities. Hierarchical regression was conducted in separate blocks guided by the socioecological model (sociodemographic, individual, and interpersonal factors) to examine the independent contribution of each block to the outcome of meeting national guidelines for muscle-strengthening PA. RESULTS: Participants who met the national PA guidelines of ≥2 days/week of muscle-strengthening activities reported significantly higher social support for PA (p < .001), greater use of behavioral strategies for PA (p < .001), and lower barriers to PA (p < .03) than those who did not meet the guidelines. Hierarchical binary logistic regression indicated behavioral strategies for PA was the only significant correlate of meeting the national guidelines for muscle-strengthening PA (odds ratio = 1.39, 95% confidence interval [1.18, 1.65], p < .001). DISCUSSION/CONCLUSION: Results support a hypothesis that instructing Latinas to use behavior change strategies could help them increase muscle-strengthening PA.

Background: Setleis syndrome (SS) is a focal facial dermal dysplasia presenting with bilateral temporal skin lesions, eyelash abnormalities and absent meibomian glands. SS is a rare autosomal recessive disorder caused by mutations in the TWIST2 gene, which codes for a transcription factor of the bHLH family known to be involved in skin and facial development. Methods: We obtained gene expression profiles by microarray analyses from control and SS patient primary skin fibroblast and lymphoblastoid cell lines. Results: Out of 983 differentially regulated genes in fibroblasts (fold change ≥ 2.0), 479 were down-regulated and 509 were up-regulated, while in lymphoblasts, 1248 genes were down-regulated and 73 up-regulated. RT-PCR reactions confirmed altered expression of selected genes. Conclusions: TWIST2 is described as a repressor, but expression profiling suggests an important role in gene activation as well, as evidenced by the number of genes that are down-regulated, with a much higher proportion of down-regulated genes found in lymphoblastoid cells from an SS patient. As expected, both types of cell types showed dysregulation of cytokine genes. These results identify potential TWIST2 target genes in two important cell types relevant to rare disorders caused by mutations in this bHLH gene.

BACKGROUND: Physical activity (PA) research extensively focuses on initiation of PA, yet lapse and relapse among PA intervention participants are less well understood, particularly among minority populations such as Latinas in the USA. This study aimed to (1) determine the probability of lapse during two PA interventions for Latinas; (2) assess demographic, psychosocial, and environmental predictors of the amount of time until first lapse; and (3) identify factors predictive of lapse recovery. METHODS: Data from 176 Latina intervention participants were pooled. Survival functions and Kaplan-Meier curves were used to illustrate probability of lapse. Cox proportional hazard models assessed predictors of time to lapse. Logistic regressions identified predictors of lapse recovery. RESULTS: The probability of lapse after 1 month of starting to exercise was 18%, escalating to 34% after 4 months. Predictors of earlier lapse included various psychosocial constructs (i.e., self-efficacy and various processes of change), but none of the measured environmental factors, and only one demographic factor (≥ 2 children under 18). Increased use of consciousness raising at 2 months was associated with lower likelihood of lapse recovery, yet use of behavioral processes of change at 6 months was associated with higher likelihood of recovery. CONCLUSIONS: Lapsing may not be pre-determined by demographic and environmental characteristics. On the other hand, skills that can be learned through interventions, such as skills to improve self-efficacy, seem important in the delay or prevention of lapses. Results pertaining to lapse recovery are less clear.
RESUMEN
The purpose of this study was to assess the effects of a pilot community-based behavioral intervention on the home food environment in U.S. households. Parents (21 females, 2 males; age = 36 ± 5.5 years; 78% Hispanic) of elementary school-aged children attended a 10-week dietary improvement behavioral intervention targeting an increase in fruit and vegetable consumption and a reduction in sugar intake. Home food availability of fruit, vegetables, and sugar-laden foods and beverages were assessed before and after the intervention using a modified version of the Home Food Inventory. Relative to baseline, the intervention resulted in significant increases in fruit availability (7.7 ± 3.2 items vs. 9.4 ± 3.1 items; p = 0.004) and low sugar cereal (2.3 ± 1.4 types vs. 2.7 ± 1.4 types; p = 0.033). There was a significant reduction in sugar-sweetened beverage availability (3.2 ± 1.9 types vs. 1.7 ± 1.3 types; p = 0.004). There was a significant increase in the number of households with accessible ready-to-eat vegetables and fruit, and a significant reduction in available prepared desserts, and candy (p < 0.01). There were no significant changes in the availability of vegetables and sugar-laden cereals. The current intervention resulted in positive changes in the home food environment. Further research to confirm these results in a randomized controlled trial is warranted.

BACKGROUND: Sedentary time is associated with chronic disease and premature mortality. We tested a multilevel workplace intervention with and without sit-stand workstations to reduce sedentary time and lower cardiometabolic risk. METHODS: Stand and Move at Work was a group (cluster) randomized trial conducted between January 2016 and December 2017 among full-time employees; ≥18 years; and in academic, industry/healthcare, and government worksites in Phoenix, Arizona and Minneapolis/St. Paul, Minnesota, USA. Eligible worksites were randomized to (a) MOVE+, a multilevel intervention targeting reduction in sedentary time and increases in light physical activity (LPA); or (b) STAND+, the MOVE+ intervention along with sit-stand workstations to allow employees to sit or stand while working. The primary endpoints were objectively-measured workplace sitting and LPA at 12 months. The secondary endpoint was a clustered cardiometabolic risk score (blood pressure, glucose, insulin, triglycerides, and HDL-cholesterol) at 12 months. RESULTS: Worksites (N = 24; academic [n = 8], industry/healthcare [n = 8], and government [n = 8] sectors) and employees (N = 630; 27 ± 8 per worksite; 45 ± 11 years of age, 74% female) were enrolled. All worksites were retained and 487 participants completed the intervention and provided data for the primary endpoint. The adjusted between arm difference in sitting at 12 months was - 59.2 (CI: - 74.6,-43.8) min per 8 h workday, favoring STAND+, and in LPA at 12 months was + 2.2 (- 0.9,5.4) min per 8 h workday. Change in the clustered metabolic risk score was small and not statistically significant, but favored STAND+. In an exploratory subgroup of 95 participants with prediabetes or diabetes, the effect sizes were larger and clinically meaningful, all favoring STAND+, including blood glucose, triglycerides, systolic blood pressure, glycated hemoglobin, LDL-cholesterol, body weight, and body fat. CONCLUSIONS: Multilevel workplace interventions that include the use of sit-stand workstations are effective for large reductions in sitting time over 12 months. Among those with prediabetes or diabetes, clinical improvements in cardiometabolic risk factors and body weight may be realized. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02566317 .

BACKGROUND: Community-based programs have had modest success in combating obesity in Latino populations. Latino families' norms and beliefs about weight often hold larger body sizes to be normal, leading to lower engagement in weight-focused programs. Because improvements in cardiorespiratory fitness confer health benefits, regardless of weight, they offer an alternative to obesity-focused approaches. We describe the rationale and design of Athletes for Life (AFL), a community- and family-based intervention for Latino families. METHODS/DESIGN: This two-group randomized controlled trial will test the efficacy of AFL for improving cardiorespiratory fitness and diet in 6- to 11-year-old children (N = 160) and their parents, relative to a wait-list control group. Children will participate in 12 weeks of semiweekly sports skill programing and nutrition sessions. Concurrently, parents will participate in sports-focused activity and behavior change sessions that focus on nutrition, chronic disease prevention, and healthy eating. Cardiovascular fitness will be measured by the 1-mile run and 3-min step-test for both parents and children. Secondary outcomes include changes in objectively measured physical activity, dietary measures, body composition, and cardiometabolic risk (waist circumference, blood pressure, blood lipids, glucose, insulin, and C-reactive protein). DISCUSSION: AFL, implemented with a strong community partnership, will provide a test of the efficacy of culturally tailored intervention programming to promote positive health behaviors and improve health outcomes in Latino families. Intervention content, structure, and messaging will provide guidance for future methods to engage Latino families in health promotion programs that highlight their cultural norms, and beliefs.

Background: Failure to recognize children's overweight status by parents may contribute to children's risk for obesity. We examined two methods of measuring mothers' perceptions of children's weight and factors associated with weight perception inaccuracy. Methods: Cross-sectional analyses of clinical and self-report data from 287 Mexican-heritage mother-child dyads. Mothers identified their child's weight category using a scale (e.g., "normal/overweight/obese") and a visual silhouette scale (11 child gender-specific weight-varying images). Children's height and weight were measured to calculate body mass index (BMI). Chi-square tests examined associations between categorical, silhouette, and BMI percentile categories of children's weight. Bivariate logistic regression analyses examined factors associated with mothers' inaccuracy of their children's weight. Results: Only 13% of mothers accurately classified their child as obese using the categorical scale, while 78% accurately classified their child as obese using the silhouette scale. Mothers were more likely to underestimate their child's weight using BMI categories (62%) compared to using the silhouette scale (23%). Predictors of mothers' underestimation using the categorical method were child sex [female] (adjusted odds ratio [AOR] = 1.99; 95% CI: 1.02-3.86), child age [younger age] (AOR = 10.39; 95% CI: 4.16-25.92 for ages 5-6 years), and mother's weight status (overweight AOR = 2.99; 95% CI: 1.05-8.51; obese AOR = 5.19; 95% CI: 1.89-14.18). Child BMI was the only predictor of mothers' overestimation (AOR = 0.89; 95% CI: 0.85-0.94) using the silhouette method. Conclusions: Using silhouette scales to identify children's body weight may be a more accurate tool for clinicians and interventionists to activate parents' awareness of unhealthy weight in children compared to using traditional categorical weight-labeling methods.

INTRODUCTION: Meat consumption has been linked to some negative health and environmental outcomes. Studies have assessed motivations among those who have reduced or eliminated meat consumption; less work identifies strategies to reduce meat consumption among those who consume meat. This paper describes factors associated with lower meat consumption and reviews experimental studies that targeted those factors to either change behavior or intention/willingness to reduce meat. METHODS: A systematic review of the literature was conducted among four databases. Inclusion criteria were experimental and quasi-experimental designs and studies that measured variables indirectly or directly related to meat consumption. RESULTS: Twenty-two articles were identified. These studies targeted factors such as knowledge and skills with informational provisions about health and the environment; values and attitudes concerning the relationship between social dominance and meat; evocation of emotion such as empathy and disgust; social norms both dynamic and growing; changes to the food environment with default vegan menu options, perceived behavioral control, and intentions. The majority of studies (nâ¯=â¯15) investigated the effects of providing information such as personal health effects of meat consumption. In general, increasing knowledge alone or when combined with other methods was shown to successfully reduce meat consumption behavior or intentions/willingness to eat meat. Evoking emotions with animal images and making changes to the environment proved effective. DISCUSSION: Factors identified in correlational studies were generally found to be useful agents of behavior change in experimental studies. However, several factors have not been tested experimentally. More experimental studies are required to confirm the results of this review; for example, experiments focused on modifications of the food environment such as increasing the number of meatless meals on restaurant menus.
