Examining the role of ethnic microaggressions and ethnicity on cortisol responses to an acute stressor among young adults.

Objective: This study examined whether the frequency of experiences of ethnic microaggressions and the sensitivity to such experiences were associated with cortisol responses to an acute social stressor (Trier Social Stress Test; TSST) among an ethnically diverse sample of young adults (N = 109, Mage = 18.82 years, SD = 1.40 years, 74% female, 44% Latinx). Method: Self-reported experiences of and sensitivity to microaggressions were assessed using the Everyday Microaggressions Scale. Participants' salivary cortisol was collected before, immediately after, and at three 15-min intervals after the TSST (for a total of 5 salivary samples) to assess their cortisol responses to an acute social stressor. Results: Mixed model analyses revealed that experiencing a higher frequency of microaggressions (p = .005) and being more sensitive to those experiences (p = .001) were associated with a more blunted cortisol response (i.e., lower cortisol reactivity and recovery) to the TSST, relative to experiencing a lower frequency of microaggressions and being less sensitive to them. Furthermore, this blunted cortisol response to the TSST was more prominent among young adults of Latinx and other ethnic backgrounds (i.e., biracial, African American, and Native American) compared to their Asian American and non-Hispanic White peers (p = .034). Conclusion: Findings provide insight into the different ways in which experiences of ethnic microaggressions can be associated with biological markers of stress.

Adiposity, Depression Symptoms and Inflammation in Hispanic/Latino Youth: Results From HCHS/SOL Youth.

BACKGROUND: Inflammation is implicated as one of many factors related to the development of chronic disease; thus, identifying its modifiable risk factors offers potential intervention targets to reduce risk. PURPOSE: To investigate whether depression and anxiety symptoms may indirectly affect high-sensitivity C-reactive protein (hs-CRP) and plasminogen activator inhibitor-1 (PAI-1) through sleep duration and adiposity (i.e., percentage body fat and waist circumference). METHODS: Multiple regression analyses were performed on Hispanic Community Health Study/Study of Latinos Youth (ages 8-16 years) cross-sectional baseline data, which were weighted to adjust for sampling design. Data were collected at a clinical assessment, including fasting blood samples, self-report surveys, and objectively measured anthropometrics. RESULTS: Adjusting for sociodemographic covariates, depression symptoms were associated with log hs-CRP (ß = .011, p = .047) but not PAI-1 (p = .285). Percentage body fat and waist circumference were positively related to depression symptoms (p = .026 and p = .028, respectively) and log hs-CRP (p < .001 for both). When including adiposity in the hs-CRP model, the associations of depression symptoms with hs-CRP were attenuated and became nonsignificant. Monte Carlo confidence intervals (CIs) showed that the indirect effects from depression symptoms to CRP through percentage body fat (95% CI: .0006, .0119) and waist circumference (95% CI: .0004, .0109) were statistically significant. CONCLUSIONS: Results indicate that the association between psychological distress and inflammation may occur indirectly through adiposity in Hispanic/Latino children. If findings are replicated in causal designs, reducing depression symptoms and adiposity among Hispanic/Latino children may be avenues for primary prevention of inflammation in later years.

Engaging Community With Promotores de Salud to Support Infant Nutrition and Breastfeeding Among Latinas Residing in Los Angeles County: Salud con Hyland's.

The Salud con Hyland's Project: Comienzo Saludable, Familia Sana [Health With Hyland's Project: Healthy Start, Healthy Family],was developed to provide education and support to Latina mothers regarding healthy infant feeding practices and maternal health. The promotora-delivered intervention was comprised of two charlas (educational sessions) and a supplemental, culturally and linguistically relevant infant feeding and care rolling calendar. Results indicate that the intervention increased intention to breastfeed exclusively, as well as to delay infant initiation of solids by 5 to 6 months. Qualitative feedback identified barriers to maternal and child health education as well as highlighted several benefits of the intervention.

Double jeopardy: metabolic syndrome leads to increased sedentary behavior in peri-pubertal minority females.

While most studies have focused on investigating the preventive effects of physical activity on metabolic risk, the longitudinal impacts of metabolic syndrome (MetS) on activity levels is poorly understood. This study aims to examine the influence of MetS on initial activity levels and the trajectory of activity levels in Latina and African American female children over 12 months (n = 55, 9 ± 1 years). Metabolic measures, including fat and lean tissue mass by BodPod, fasting glucose, lipids, blood pressure, and waist circumference, were collected at baseline. Moderate-to-vigorous physical activity and sedentary behavior by accelerometry were collected on a quarterly basis. There were no significant differences in either initial activity levels by MetS status (Moderate-to-vigorous physical activity: 33 ± 12 mins/day for MetS, 48 ± 28 mins/day for Non-MetS, p = .12; sedentary behavior: 408 ± 57 mins/day for MetS, 421 ± 72 mins/day for Non-MetS, p = .67). Longitudinal declines in moderate-to-vigorous physical activity (p = .038) and increases in sedentary behavior (p = .003) were found. Daily sedentary behavior increased by 82.64 more minutes in youth with MetS than in those without over one year (p = .015). This study yields the first evidence of the adverse effect of MetS on sedentary behavior. Targeted intervention strategies to reduce progressive sedentariness evident in minority youth with MetS are warranted.

Longitudinal associations between biopsychosocial stress indicators and sleep in older Puerto Rican adults.

OBJECTIVES: To examine the association of biopsychosocial stress indicators (perceived stress, perceived discrimination, stressful life events, and allostatic load) with sleep outcomes (sleep duration and insomnia symptoms) and to examine sex and age interactions for associations between stress and sleep in older Puerto Rican adults. METHODS: Secondary analyses were performed with 830 participants (72% female) from wave 2 (2006-2011) of the Boston Puerto Rican Health Study (BPRHS), a prospective population-based cohort study (45-75years at baseline) and Boston Puerto Rican Osteoporosis Study (BPROS) (2007-2012), an ancillary study of the BPRHS. Recruitment occurred in randomly selected census blocks using door-to-door and community-based activities. In-home data collection visits included a baseline assessment and follow-up interviews. Questionnaires assessed perceived stress, discrimination, stressful life events, and sleep. Allostatic load indicators were measured objectively. Regression models controlled for sociodemographic, behavioral, and health factors, with interaction analyses, followed by sex- and sex-by-age-stratified analyses. RESULTS: In the prior 2years, participants with chronic stress had 50% greater odds of reporting nonoptimal sleep duration (<7 or >9 hours). Life events trajectories were significantly related to insomnia symptoms. Men ≥65years who experienced chronic stress had greater insomnia symptoms than women, or than men with low stress or acute stress. CONCLUSIONS: Stressful life events may affect sleep duration and insomnia symptoms among older Puerto Rican adults, particularly men 65 years and older who experienced chronic stress. Given the differences in sleep patterns experienced by older adults and their relationships with health outcomes, identifying methods to support sleep health among those with chronic stress is important.

Influence of Home Language Use on the Association Between Parent Education and Child Adiposity in Latino Families.

BACKGROUND: Parent education and language use are associated with child obesity, but the impact of their interaction is less known. This study assessed whether parent education was associated with child adiposity and if this association was moderated by home language use in Latino families. METHODS: Participants (n = 415) were Latino families from the Long Beach area. Demographic data were obtained by self-report parent surveys, and children's body size was objectively assessed via bioelectric impedance. Independent t-tests and hierarchical linear regressions were performed on baseline data from a larger intervention study. RESULTS: In the overall sample, parent education and child body mass index (BMI) percentile were not related (p = .050). However, stratification by home language use revealed that parent education was inversely associated with child BMI percentile among those whose primary home language was Spanish (p = .049), but not English/bilingual homes (p = .296). There were no significant associations with child percent body fat. CONCLUSION: Higher education was associated with a lower BMI percentile only in Spanish-speaking homes. Research to understand how home language influences this relationship is warranted, particularly as it relates to a subset of education and health literacy. Significant results with BMI percentile but not percent body fat highlight the fact that these distinct markers of obesity are not interchangeable.

Longitudinal Associations Between Sleep and Cognitive Function in a Cohort of Older Puerto Rican Adults: Sex and Age Interactions.

BACKGROUND: Evidence on sleep duration or quality and cognitive function in diverse older adults is limited. We examined prospective associations between subjective sleep measures and cognitive function, with modifying effects of sex and age (<65 vs ≥65 years). METHODS: Data are from the longitudinal Boston Puerto Rican Health Study, Waves 2 (n = 943) and 4 (n = 444), with mean follow-up of 10.5 years (range 7.2-12.8). Subjective measures of sleep duration (short <7, ref. 7, or long ≥8 hours) and insomnia symptoms (sum of difficulty falling asleep, waking up at night, and early morning awakening), were assessed at Wave 2. Linear regression models were used to assess changes in global cognition, executive function, memory, and Mini-Mental State Examination, and tested for modifying roles of sex and age. RESULTS: Significant 3-way interaction (sex × age × cognition) in fully adjusted models showed greater decline in global cognitive function in older men with short (ß [95% confidence interval]: -0.67 [-1.24, -0.10]) or long sleep duration (-0.92 [-1.55, -0.30]), compared to women, younger men, and older men with 7 hours of sleep. Insomnia symptoms were associated with a greater decline in memory (-0.54, [-0.85, -0.22]) among older men, compared to women and younger men. CONCLUSION: Sleep duration showed a U-shaped association with cognitive decline, and insomnia symptoms were associated with memory decline in fully adjusted models. Older men, versus women and younger men, were at relatively greater risk for cognitive decline associated with sleep factors. These findings are important for personalizing sleep interventions to support cognitive health.

Comprando Rico y Sano: Increasing Latino Nutrition Knowledge, Healthful Diets, and Food Access Through a National Community-Based Intervention.

PURPOSE: Evaluation findings from Comprando Rico y Sano (CRS), a culturally relevant, community-based intervention addressing nutrition knowledge and food access are presented. DESIGN: No-control quasi-experimental intervention with pre, post, and follow-up assessments. SETTING: CRS was promotores-led through UnidosUS's Affiliate Network of community-based partners. SAMPLE: Low-income Latino adults (N = 966) receiving services at 25 partner sites. INTERVENTION: CRS was a six-hour intervention focused on nutrition knowledge and consumption of fruits, vegetables, and home-prepared meals. It also provided guidance for health-conscious grocery shopping, Supplemental Nutrition Assistance Program (SNAP) information, and enrollment assistance. MEASURES: Self-report surveys assessed nutrition knowledge; intention to change; and frequency of fruit, vegetable, and home-prepared meal consumption. Sites reported monthly SNAP enrollment data. ANALYSIS: Paired-samples t-tests and repeated-measures ANOVAs assessed changes in knowledge, intentions, and behavior from pre-to-post (n = 960) and pre-to-follow-up (n = 115). RESULTS: Pre-to-follow-up increases in nutrition knowledge (P < .001) were observed. Intention to consume more vegetables (P = .027) and home-prepared meals (P < .001) also improved between pre- and follow-up. Increases from pre-to-follow-up were observed for frequency of consuming fruits (P = .007), vegetables (P = .001), and home-prepared meals (P < .001). Across 16 months, 24,359 Latinos enrolled for SNAP. CONCLUSION: Large-scale community collaborations to deliver culturally relevant nutrition education and SNAP enrollment assistance can increase food access, health literacy, and promote healthful diets for Latinos.

Recruitment and retention of African American and Latino preadolescent females into a longitudinal biobehavioral study.

OBJECTIVE: Addressing recruitment challenges faced by researchers when the intended participants are young individuals from minority communities is crucial to prevent increases in study costs, prolonged length of the study, and loss of generalizability that may occur due to the resulting higher attrition rates. This article focuses on understanding the differences in census-tract level income, education, and socioeconomic status of young Latina and African American female participants and non-participants during the first 26 months of recruitment (June 2006-August 2008) in a longitudinal biobehavioral study. DESIGN: The Transitions Study examines the psychological and physiological determinants influencing the decrease in physical activity during puberty among Latina and African American girls aged 8 to 11 years within the greater Los Angeles area. Recruitment and retention through five main steps in the process were examined: telephone contact, telephone screening, consent, clinical screening, and baseline overnight visit. RESULTS: As of August 2008, the recruitment pool consisted of 110 African Americans (17.8%) and 373 Latinas (60.4%); of these, only 40 Latinas and 11 African American girls completed the final step into the study. African Americans were less willing to provide their phone numbers, but more likely to be reached at initial phone contact than Latino families. CONCLUSIONS: Understanding the heterogeneity within minority populations, population characteristics, through careful and timely analyses, could be used to adjust recruitment and retention strategies in a study involving minority youth.

Psychosocial correlates of eating behavior in children and adolescents: a review.

BACKGROUND: Understanding the correlates of dietary intake is necessary in order to effectively promote healthy dietary behavior among children and adolescents. A literature review was conducted on the correlates of the following categories of dietary intake in children and adolescents: Fruit, Juice and Vegetable Consumption, Fat in Diet, Total Energy Intake, Sugar Snacking, Sweetened Beverage Consumption, Dietary Fiber, Other Healthy Dietary Consumption, and Other Less Healthy Dietary Consumption in children and adolescents. METHODS: Cross-sectional and prospective studies were identified from PubMed, PsycINFO and PsycArticles by using a combination of search terms. Quantitative research examining determinants of dietary intake among children and adolescents aged 3-18 years were included. The selection and review process yielded information on country, study design, population, instrument used for measuring intake, and quality of research study. RESULTS: Seventy-seven articles were included. Many potential correlates have been studied among children and adolescents. However, for many hypothesized correlates substantial evidence is lacking due to a dearth of research. The correlates best supported by the literature are: perceived modeling, dietary intentions, norms, liking and preferences. Perceived modeling and dietary intentions have the most consistent and positive associations with eating behavior. Norms, liking, and preferences were also consistently and positively related to eating behavior in children and adolescents. Availability, knowledge, outcome expectations, self-efficacy and social support did not show consistent relationships across dietary outcomes. CONCLUSION: This review examined the correlates of various dietary intake; Fruit, Juice and Vegetable Consumption, Fat in Diet, Total Energy Intake, Sugar Snacking, Sweetened Beverage Consumption, Dietary Fiber, Other Healthy Dietary Consumption, and Other Less Healthy Dietary Consumption in cross-sectional and prospective studies for children and adolescents. The correlates most consistently supported by evidence were perceived modeling, dietary intentions, norms, liking and preferences. More prospective studies on the psychosocial determinants of eating behavior using broader theoretical perspectives should be examined in future research.

Psychological determinants of emotional eating in adolescence.

Emotional eating is conceptualized as eating in response to negative affect. Data from a larger study of physical activity was employed to examine the associations among specific emotions/moods and emotional eating in an adolescent sample. Six-hundred and sixty-six students of diverse backgrounds from 7 middle schools in Los Angeles County participated. Cross-sectional analysis revealed no gender differences in emotional eating, and showed that perceived stress and worries were associated with emotional eating in the total sample. Gender stratified analyses revealed significant associations of perceived stress, worries and tension/anxiety to emotional eating for girls, while only confused mood was related to emotional eating in boys. These findings bear potential implications for the treatment and prevention of pediatric obesity and eating disorders because they suggest that interventions would benefit from incorporation of stress-reduction techniques and promotion of positive mood.

Age, Physical Activity Motivation and Perceived Stress in Minority Girls.

BACKGROUND: Physical activity in childhood and adolescence helps support physical and emotional health. PURPOSE: The study aimed to investigate if age was related to motivation for physical activity in minority girls, and whether the relationship may be potentially mediated by psychological or physiological stress. METHODS: This cross-sectional observational study recruited Latino and African American girls ages 8 - 12 years (n = 79) in Tanner stage 1 or 2 via purposive sampling. Intrinsic motivation and perceived stress were measured by self-report survey; morning salivary cortisol samples were taken to calculate cortisol awakening response to estimate biological stress reactivity. RESULTS: Increased age was related to higher intrinsic motivation to engage in physical activity. Lower perceived stress and lower awakening cortisol response were associated with higher intrinsic motivation. Bootstrapped mediation results indicated perceived stress may be a pathway through which age impacts intrinsic motivation for physical activity. CONCLUSION: While motivation to engage in physical activity may increase with age, perceived stress may dampen this motivation, resulting in decreased physical activity. Interventions to help increase pre-adolescent girls' engagement in active behaviors may benefit from reducing children's perceptions of stress.

BMI as a moderator of perceived stress and emotional eating in adolescents.

Emotional eating has often been linked to overweight and/or obesity. Multiple group SEM analyses were conducted using cross-sectional data from 517 minority students in Los Angeles County. Results showed no differences in emotional eating between normal weight and overweight students. Perceived stress was indeed a significant correlate of emotional eating, independent of BMI status, as indicated by the lack of a modifying effect of BMI status. Findings highlight the fact that emotional eating is not an issue only for overweight and obese persons. This study shows that some children in this population at increased risk for obesity and related chronic disease have already incorporated emotional eating as a learned response to stress by the time that they enter adolescence.

Coping mediates the effects of depressive symptoms on sleep problems.

OBJECTIVES: To explore the relationships of perceived stress and depressive symptoms to sleep problems, testing for mediation by adaptive and maladaptive coping strategies. METHODS: Alternative high school students (N = 1676) completed self-report surveys. Cross-sectional data were analyzed via Preacher and Hayes' procedures for multiple mediation. RESULTS: The positive relationship between depressive symptoms and sleep problems was mediated partially by anger coping (positively related to sleep problems). The positive relationship between perceived stress and sleep problems was not mediated by coping strategies. CONCLUSIONS: Findings provide information on psychological factors that may lead to poor sleep outcomes, and are useful for developing health promotion interventions to impact lifelong health behaviors.

Eating breakfast more frequently is cross-sectionally associated with greater physical activity and lower levels of adiposity in overweight Latina and African American girls.

BACKGROUND: Eating breakfast is believed to promote a healthy body weight. Yet, few studies have examined the contribution of energy balance-related behavioral factors to this relation in minority youth. OBJECTIVE: We assessed the associations between breakfast consumption and dietary intake, physical activity (PA), and adiposity before and after accounting for energy intake and PA in minority girls. DESIGN: Cross-sectional data were obtained on body mass index (BMI), percentage body fat (measured by BodPod), dietary intake (measured with 3-d dietary records), and PA (measured with 7-d accelerometry) from 87 Latina and African American girls 8-17 y of age (75% Latina, 80% overweight). Dietary records were used to categorize girls as more frequent breakfast eaters (MF; 2 or 3 of 3 d; n = 57) or less frequent breakfast eaters (LF; 0 or 1 of 3 d; n = 30). Chi-square tests, ANCOVA, and multiple regression analyses were conducted. Mediation was assessed with a Sobel test. RESULTS: Compared with the MF group, the LF group spent 30% less time (12.6 min/d) in moderate-to-vigorous-intensity PA (MVPA; P = 0.004) and had a higher percentage body fat (P = 0.029). MVPA accounted for 25% (95% CI: -8.8%, 58.1%; P = 0.139) of the relation between breakfast consumption and percentage body fat. We were unable to show that energy intake or MVPA was a significant mediator of the relation between breakfast consumption and adiposity in this sample. CONCLUSIONS: Evidence suggests that among predominantly overweight minority girls, MVPA, but not energy intake, was associated with both breakfast consumption and adiposity; however, a lack of power reduced our ability to detect a significant mediation effect. Other unobserved variables likely contribute to this relation.

Influences of social support, perceived barriers, and negative meanings of physical activity on physical activity in middle school students.

BACKGROUND: A profound decline in physical activity occurs in puberty. This phenomenon is not well understood. Therefore, the purpose of this study is to examine associations between family/friend social support for physical activity, negative meanings of physical activity (NMPA), and internal /external barriers to physical activity with moderate to vigorous physical activity (MVPA), and sedentary and light behavior (SLB) in youth. METHODS: A total of 350 participants from 7 Los Angeles County middle schools participated in the study (62% Latina, 79% females). Hypothesized pathways were examined using structural equation modeling. Psychosocial variables and participation in MVPA and SLB were assessed by self-reported questionnaires. RESULTS: NMPA were related to lower levels of family/friend social support and greater internal/external barriers. Family social support was the only significant indicator of MVPA (ß=0.79). Low family social support was related to higher SLB (ß=-0.25). CONCLUSIONS: Family social support seems crucial to promote MVPA and reduce SLB in adolescents and might be influenced by child's feelings about physical activity. Future research should consider the interrelationship between psychosocial correlates of physical activity.

Measuring the meanings of eating in minority youth.

The aim of this study is to present the development of the Meanings of Eating Index (MEI) in a diverse sample of children. Exploratory factor analysis was performed on MEI items. Factors with eigenvalues above 1.0 were retained. Items that loaded on multiple factors or with item-total correlations below 0.50 were discarded. A 24-item, 5-factor scale comprised the final MEI. Personal Negative Emotions and Disturbed Eating were positively associated with frequency of high calorie snack food intake (r=0.21, p<0.05; r=0.33, p<0.01), and Personal Well Being was positively associated with eating vegetables more frequently (r=0.20; p<0.05). Eating on Behalf of Others was negatively associated with frequency of vegetable intake (r=-.20; p<0.05). Pleasure Eating was not associated with dietary intake. The MEI shows promise as a tool for understanding the affective determinants of dietary intake in minority youth.

The influence of worries on emotional eating, weight concerns, and body mass index in Latina female youth.

PURPOSE: To investigate the effect of worries on weight concerns, emotional eating, and body mass index (BMI) percentile in an ethnically diverse sample of female youth. METHODS: This study used baseline and follow-up data from a brief school-based physical activity intervention trial involving minority female youth. Partial correlations adjusted for intervention status, age, and ethnicity were used to assess the relationships between emotional eating, weight concerns, and BMI percentile at follow-up. Multilevel modeling was used to analyze the relationships between baseline worries and follow-up emotional eating, weight concerns, and BMI percentile. Additional analysis assessed whether emotional eating mediated and/or moderated the relationship between baseline worries and follow-up BMI. Data were analyzed using SAS version 9.1. RESULTS: The sample consisted of 404 minority females (67.1% Latina; mean age = 12.5 ± .6; 60.6% were of normal weight). Weight concerns were positively correlated with emotional eating and BMI percentile (p < .001 for both). At follow-up, baseline worries significantly predicted emotional eating (p = .027) and weight concerns (p < .001) but not BMI percentile (p = .183). Emotional eating did not mediate the relationship between baseline worries and follow-up BMI percentile; however, it did moderate the relationship between baseline worries and follow-up BMI percentile (p = .003). CONCLUSIONS: In this sample, worries were associated with psychosocial variables but not with BMI percentile. Reducing worries in those with high emotional eating scores may influence future weight gain among Latina females.

Anxiety mediates the relationship between sleep onset latency and emotional eating in minority children.

This study examined associations between sleep onset latency and emotional eating in a minority sample of children. A cross-sectional school-based study of sleep, psychological constructs, diet and physical activity was conducted in 6 public and private schools in Los Angeles County. An ethnically diverse sample of 356 third through fifth graders completed confidential self-report surveys. Multilevel regression (MLM) analyses were conducted to study associations while controlling for gender, ethnicity, and the random effect of school. Girls made up 57% of the total sample, which was predominantly Latino (42.6%), followed by African Americans (21.6%) and Asians (19.2%). MLM revealed that there were significant associations between sleep onset latency and emotional eating (p=.030), depressive symptomology (p<.0001) and trait anxiety (p<.0001). Sobel's test for mediation showed that trait anxiety (p=.011) but not depressive symptomology (p=.141) was a mediator of the relationship between sleep onset latency and emotional eating. Thereby providing a mechanism through which sleep onset latency is related to emotional eating. These findings suggest that sleep onset latency is associated with increased anxiety, depressive symptoms, and emotional eating. Although causal inferences cannot be drawn from this cross-sectional data, future studies should examine the possibility that problems falling asleep could lead to emotional dysregulation that in turn leads to emotional eating. Emotional eating may be one avenue by which sleep disturbances lead to overweight and obesity.
