Description
Background: Latinos have disproportionately high rates of obesity and type 2 diabetes. Family-based interventions may reduce chronic disease risk among Latinos across generations.
Purpose: To assess the efficacy of Athletes for Life (AFL), a 12-week community-and-family-based behavioral intervention, for improving diet, physical activity (PA), anthropometrics, fitness, and biochemical outcomes among mostly Latino parents.
Methods: Parents with at least one child 6-11 years of age were randomized to active AFL participation (n=14) or a wait-list control (n=14) group. AFL consisted of twice weekly 90 minute sessions (45 minutes of nutrition-focused lessons and 45 minutes of PA participation) designed to promote fruit and vegetable consumption, reduction of sugar intake, and increasing habitual PA. Data were collected prior to and immediately after the 12 week intervention.
Results: Participants (37.9±7.2y) were mostly Latino (93%), Spanish speaking (68%), and women (93%). Relative to participants in the control group, AFL participants had a significant reduction in body fat (-1.1±1.2% vs. 0.2±1.2%; p=0.014), resting (-7.6±10.2 bpm vs. +2.1±6.8 bpm; p<0.01), exercise (-8.4±8.7 bpm vs. +0.4±7.3 bpm; p<0.01), and recovery heart rate (-11.9±12.8 bpm vs. -0.3±11.4 bpm; p=0.01), and one mile run time (-1.5±1.0 min vs. -0.1±0.9 min; p<0.01), and a significant increase in estimated VO2 peak (+1.9±1.9 ml/kg/min vs. 0.0±1.8 ml/kg/min; p=0.01). AFL participants also reported an increase in the number of days/week accumulating 30 minutes of MVPA (+0.8±3.2 vs. -1.5±2.3; p=0.004) and daily servings of fruits (+1.3±1.4 vs. +0.3±1.4; p<0.05) and vegetables (+1.8±1.7 vs. +0.1±1.2; p<0.05), relative to control participants. There were no significant differences between groups in changes in diet assessed by 3-day food record, accelerometer-measured PA, weight, blood pressure, visceral fat, biomarkers for cardiovascular disease or nutritional biomarkers.
Conclusions: Despite the lack of effects on diet and PA behaviors, AFL shows promising preliminary efficacy for reducing body fat and improving fitness among adult participants. Future research aimed at improving fitness among Latino parents with family-based intervention is warranted.

Description
Se examinan desde una perspectiva autobiográfica las obras de Yolanda Cruz, Saúl Cuevas, Víctor Fuentes, John Leguizamo, Gustavo Pérez-Firmat, Roberto Quesada, y Esmeralda Santiago bajo los filtros de los espacios creados por la migración y/o el exilio, para lo cual se toma en cuenta el bagaje cultural de objetos que cada uno de estos autores aporta en el panorama cultural euiberolatino en los Estados Unidos. Para su análisis crítico, se consideran en un primer plano el pensamiento en Imaginary Communities: Utopia, the Nation, and the Spatial Histories of Modernity (2002) de Phillip Wegner sobre las comunidades imaginarias creadas desde los espacios utópicos que se convierten en realidad desde un enfoque sociohistórico en un ambiente de Estado moderno. Asimismo, se interpreta la ideología como Misplaced Objects; Migrating Collections and Recollections in Europe and the Americas (2009) de Silvia Spitta sobre los objetos desubicados y la transformación que conlleva con dicho movimiento vía el desplazamiento en los espacios de migración y exilio de los autores en este estudio. Se consideran ciertas similares aportaciones existentes como Hispanic New York: A Sourcebook (2010) de Claudio Iván Remeseira cuyo estudio particular enfoca a unos habitantes euiberolatinos de la gran urbe neoyorquina. Para redondear el pensamiento crítico se ha incluido la obra Lugares decoloniales: Espacios de intervención en las Américas (2008), editada por Ramón Grosfoguel y Roberto Almanza Hernández. Este enfoque funciona como el marco crítico para la perspectiva de nuestro texto que examina los bagajes culturales de las regiones como Zacatecas-Durango y Oaxaca, México; La Habana, Cuba; Santurce, Puerto Rico; Olanchito, Honduras; Bogotá, Colombia y Madrid, España y hasta los de sus nuevos espacios en Phoenix, Los Ángeles, Miami-Chapel Hill, Manhattan, Queens y Santa Bárbara, en los Estados Unidos y más allá en Latinoamérica, Europa y África.

Description
Through three investigations, this dissertation examined properties of the family and early care and education center (ECEC) environments related to preschool-aged children’s cardiovascular fitness (CVF) and gross locomotor skills (GLS). Investigation one used a systematic review and meta-analysis to synthesize the effectiveness of school-based interventions at improving CVF, in preschool-aged children. For investigations two and three product- and process-based measures of GLS were collected from children in ECECs (n=16), using the progressive aerobic cardiovascular endurance run (PACER; n=144) and the CHAMPS motor skill protocol (CMSP; n=91), respectively. Investigation two and three examined family factors and ECEC factors for associations with measures of GLS, respectively.
Investigation one revealed a moderate-to-large effect size for school-based interventions (n=10) increasing CVF (g=0.75; 95%CI [0.40-1.11]). Multi-level interventions (g=.79 [0.34-1.25]) were more effective than interventions focused on the individual (g=0.67 [0.12-1.22]). In investigations two and three children (78.3% Hispanic; mean ± SD age 53.2±4.5 months) completed a mean ± SD 3.7±2.3 PACER laps and 19.0±5.5 CSMP criteria. Individual and family factors associated with PACER laps included child sex (B=-0.96, p=0.03) and age (B=0.17, p<0.01), parents’ promotion of inactivity (B=0.66, p=0.08) and screen time (B=0.65, p=0.05), and parents’ concern for child’s safety during physical activity (B=-0.36, p=0.09). Child age (B=0.47, p<0.01) and parent employment (B=2.29, p=0.07) were associated with CMSP criteria. At the ECEC level, policy environment quality (B=-0.17; p=0.01) was significantly associated with number of PACER laps completed. Outdoor play environment quality (B=0.18; p=0.03), outdoor play equipment total (B=0.32; p<0.01) and screen time environment quality (B=0.60; p=0.02) were significantly associated with CMSP criteria. Researchers, ECEC teachers and policy makers should promote positive environmental changes to preschool-aged children’s family and ECEC environments, as these environments have the potential to improve CVF and GLS more than programs focused on the child alone.

Description
Objectives. This study primarily explored the relationship between family meal frequency and youth intake of fruits and vegetables (FV) and added sugar from sugar-sweetened beverages (SSBs) in a population of Latinx parents and their middle school children. The study secondarily explored factors influencing family meal frequency; specifically, whether parent education level, income level, acculturation level, and food insecurity are associated with family meal frequency.
Methods. Latinx parents and their 6th-8th grade children were recruited from eligible middle schools in Maricopa County to participate in a larger intervention study. A sample of parent-youth dyads from the first cohort of the larger study was selected for cross-sectional analysis of baseline data in this study (n=124). Participants completed a survey requesting demographics, family meal habits, and dietary intake. Participants were asked to report annual income, education level, and number of family meals in the home in the past week. They were also asked to complete an Acculturation Rating Scale for Mexican Americans, a 6-item Household Food Security Questionnaire, and a 26-question Dietary Screener Questionnaire. Analyses were run using Spearman’s Rank Correlation test and a Chi Square test of Independence.
Results. Mean daily youth intake of FV was 2.7 ± 1.4 cup equivalents, and daily youth intake of sugars from SSBs was 8.6 ± 4.9 teaspoon equivalents per day. Fifty percent of parents reported 7 or more family meals per week, while 38.7% reported 3-6 family meals per week and 11.3% reported 2 or fewer family meals per week. There was no significant association between family meal frequency and youth FV (r=-0.154; p=0.256) or added sugar from SSBs (r=0.027; p=0.807) intake. Similarly, results from Chi Square analyses suggested there was no association between family meal frequency and parent income level (p=0.392), Mexican-oriented acculturation level (p=0.591), Anglo-oriented acculturation level (p=0.052) and food insecurity (p=0.754). In contrast, a significant association between parent education and family meal frequency was found (p=0.014).
Conclusions. Parent education may play a role in shaping family meal practices in Latinx families. More research is needed to further understand this relationship and the relationship between family meal habits and youth dietary intake.
