Randomized control trial of a childhood obesity prevention family-based program: "Abriendo Caminos" and effects on BMI.

Background: Hispanic individuals are at increased risk for obesity and other chronic health conditions. This article evaluates the effect of a family-based, childhood obesity primary prevention intervention in a community setting. Methods: A multi-site, randomized controlled trial community program with assessments at pre (T0), post-program (T1), and 6-months post-program (T2). Participating families were recruited from five sites. Only families of Mexican or Puerto Rican heritage with a least one child between 6 and 18 years were included in the study, without weight restrictions. Families were randomized to the intervention and control arms. Intervention families received six-2 h weekly workshops. Control families received printed generic nutrition and wellness information. Heights and weights were measured at the 3-time points to calculate BMI z-scores, BMI-percentiles, and weight status using age- and sex-specific growth charts, according to the CDC guidelines. Results: There were no differences in BMI-z scores between children in the intervention (n = 239) and control groups (n = 187) at T0. BMI z-scores decreased in the intervention group (-0.03, 95% CI, -0.066, -0.003, p = 0.032) at T1, but not in the control group at T1. Changes in BMI z-scores were not statistically significant at T2. Conclusion: The Abriendo Caminos intervention effectively prevented unhealthy weight gain in Hispanic children in the short-term, but not at 6-months post-intervention. Younger children and girls benefited more from the program at 6-months post-intervention. Additional efforts are needed to sustain long-term changes. Culturally-tailored programs can provide families with the knowledge to produce short-term changes and a potential pathway for sustainable changes in implementing healthy behaviors.

Cultural Influences on Family Mealtime Routines in Mexico: Focus Group Study with Mexican Mothers.

Mexico's obesity rates are alarming, and experts project drastic increases in the next thirty years. There is growing interest in understanding how remote acculturation and globalization processes influence health behaviors. The present study used focus group data from a central state, San Luis Potosí, in Mexico to explore mothers' perspectives on factors that influence family mealtime routines. Thematic analysis was used to identify barriers and facilitators to healthy mealtime routines and diet within families. Twenty-one mothers participated in the focus groups; 76% were full-time stay at home mothers, the majority were low-income (65%), and fewer than half reached a high school education. Three major themes emerged: (1) mothers do most of the visible work involving mealtime routines; (2) family meals are different today, and globalization is a contributing factor; and (3) family mealtimes are shifting to weekend events. Empowering mothers to negotiate diet with family members to build healthy routines, navigate challenges due to changing environments, and set family boundaries around technology use during mealtimes should be taken into consideration when promoting healthy behaviors with Mexican families.

How Well Can Family Childcare Providers Report on Preschoolers' Motor Skill Competence?

BACKGROUND: Assessing children's movement skill competence objectively is resource and time intensive. Family childcare providers (FCCPs) are with young children for most of a normal weekday and may have an understanding of their motor skill competence. OBJECTIVE: This study examined how well FCCPs can report on preschoolers' motor skills. METHOD: Seventy-eight 3-5 year olds (53.1% girls) from 26 FCCPs participated. The Test of Gross Motor Development-2 assessed actual motor skill competence and a survey assessed preschoolers' motor competence as reported by FCCPs. Bivariate correlations examined associations between actual and FCCPs' proxy-report of preschoolers' motor skill competence. Regression models tested the predictive power of FCCPs' proxy-report on actual preschoolers' motor skill competence, accounting for age and sex. RESULTS: There were moderate significant correlations for locomotion (r = .30), object control (r = .38), and overall motor skill competence (r = .36). The regression models showed proxy report was statistically associated with preschoolers' object control skills (ß = .78, p = .011) and overall motor skills (ß = .72, p = .022), but not locomotor skills (ß = .52, p = .084). FCCPs' proxy-report of preschoolers' motor skill competence explained 20.9, and 20.1% of preschoolers' variance in object control, and overall motor skill competence, respectively after adjusting for biological sex and age (increasing). CONCLUSIONS: FCCPs may be used as an alternative source of information in reporting young children's actual motor skill competence, at least for the object control domain. There is an opportunity for education of FCCPs regarding children's locomotor skill development.

Predictors and Outcomes of Mealtime Emotional Climate in Families With Preschoolers.

Objective: Mealtime emotional climate (MEC) is related to parent feeding and mental health, and possibly to child food consumption. However, MEC has been inconsistently assessed with a variety of coding schemes and self-report instruments, and has not been examined longitudinally. This study aims to characterize MEC systematically using an observational, count-based coding scheme; identify whether parent feeding or mental health predict MEC; and examine whether MEC predicts child food consumption and weight. Methods: A subsample of parents (n = 74) recruited from a larger study completed questionnaires when children were about 37 months, participated in a home visit to videotape a mealtime when children were about 41 months, and completed questionnaires again when children were about 51 months old. Maternal and child positive and negative emotions were coded from videotaped mealtimes. Observational data were submitted to cluster analyses, to identify dyads with similar emotion expression patterns, or MEC. Logistic regression was used to identify predictors of MEC, and Analysis of Covariance was used to examine differences between MEC groups. Results: Dyads were characterized as either Positive Expressers (high positive, low negative emotion) or All Expressers (similar positive and negative emotion). Increased food involvement feeding practices were related to decreased likelihood of being an All Expresser. Positive Expressers reported that their children ate more healthy food, compared with All Expressers. Conclusions: Observed MEC is driven by maternal emotion, and may predict child food consumption. Food involvement may promote positive MEC. Improving MEC may increase child consumption of healthy foods.

Validation of the SCOFF questionnaire for screening of eating disorders among Mexican university students.

PURPOSE: To evaluate the criterion validity and diagnostic utility of the SCOFF, a brief eating disorder (ED) screening instrument, in a Mexican sample. METHODS: The study was conducted in two phases in 2012. Phase I involved the administration of self-report measures [the SCOFF and the Eating Disorder Inventory-2, (EDI-2)] to 1057 students aged 17-56 years (M age = 21.0, SD = 3.4; 67 % female) from three colleges at the Universidad Autónoma de San Luis Potosí, Mexico. In Phase II, a random subsample of these students (n = 104) participated in the eating disorder examination, a structured interview that yields ED diagnoses. Analyses were conducted to evaluate the SCOFF's criterion validity by examining (a) correlations between scores on the SCOFF and the EDI-2 and (b) the SCOFF's ability to differentiate diagnosed ED cases and non-cases. RESULTS: EDI-2 subscales showed high correlations with the SCOFF scores proving initial evidence of criterion validity. A score of two points on the SCOFF optimized the sensitivity (78 %) and specificity (84 %). With this cutoff, the SCOFF correctly classified over half the cases (PPV = 58 %) and screened out the majority of non-cases (NPV = 93 %) providing further evidence of criterion validity. Analyses were repeated separately for men and women, yielding gender-specific information on the SCOFF's performance. CONCLUSIONS: Taken as a whole, results indicated that the SCOFF can be a useful tool for identifying Mexican university students who are at risk of eating disorders.

Promotoras and the Semantic Gap Between Latino Community Health Researchers and Latino Communities.

Promotoras are identified as a unique group of community health workers adept at reducing health disparities. This qualitative study was conducted to better understand perceptions of the term promotora, broadly used in research but not well documented in everyday Latina vocabulary. Six focus groups to better understand perceptions of the term promotora were conducted with 36 Latina women living in three nonmetropolitan areas in Illinois. Results suggest that Latina participants in the study do not understand the meaning of "promotora" in the same way as it is used in the literature. Latina participants understood "promotoras" as referring to people who sell or deliver information, or organize events in the community that are not necessarily related to health events or community health work. Furthermore, they usually understood the term to refer to paid work rather than volunteering. Results underscore the importance of being sensitive to Latinas' perceptions of community health terminology by assessing their context, needs, and expectations. These findings call researchers' attention to the need to educate certain Latino communities about the concept of promotoras, with implications for the implementation and dissemination of promotora-led community health programs, as the semantic discrepancy could affect the recruitment of promotoras as well as community participation in the programs they deliver.

Associations between adult attachment style, emotion regulation, and preschool children's food consumption.

OBJECTIVE: The goal of this study was to test 3 serial mediation models of how caregiver adult attachment style influences children's food consumption through its influence on emotion regulation. Three mediators that have been shown to increase the risk for pediatric obesity and that are likely to be influenced by negative emotion regulation strategies in everyday family interactions were chosen: (1) caregiver feeding practices (2) family mealtime routines, and (3) child television (TV) viewing. METHOD: A total of 497 primary caregivers of 2.5- to 3.5-year-old children reported on their own attachment style, typical responses to their children's negative affect, feeding styles, mealtime and TV viewing routines, and their children's consumption of healthful and unhealthful foods. RESULTS: Insecure mothers were more likely to use punishing or dismissing responses to their children's negative affect, and negative emotion regulation predicted the increased use of emotion-related feeding styles and fewer mealtime routines. These variables, in turn, were found to predict children's unhealthful food consumption, documenting serial mediational influences. With respect to TV viewing, caregiver insecurity influenced child food consumption indirectly through its direct effect on child TV viewing. CONCLUSION: Taken together, these data suggest that insecure attachment may put parents at a risk for using negative emotion regulation strategies in response to their children's distress, which may also have important implications for the interpersonal environment surrounding food and the development of children's early eating behaviors.

Six-week Latino family prevention pilot program effectively promotes healthy behaviors and reduces obesogenic behaviors.

OBJECTIVE: To test the effectiveness of a 6-week family-based healthy eating pilot program aimed to reduce obesogenic behaviors among Latino parents and children. METHODS: A 6-week healthy eating pilot program focused on dietary changes within Latino families with a 6- to 13-year-old child. A 1-group, pre-posttest design with 2-month follow-up examining fruit, vegetable, and sugar-sweetened beverage consumption. RESULTS: The program was effective at increasing parent-report of child fruit consumption, (P < .001, effect size = .26), vegetable consumption, (P = .001, effect size = .20), and decreasing sugar-sweetened beverage consumption, (P = .002, effect size = .16). CONCLUSIONS AND IMPLICATIONS: This family-based prevention program was effective at improving healthy eating in Latino families, especially for children. The curriculum can be used in future prevention programs for Latino families with a 6- to 13-year-old child.

Evaluation of the psychometric performance of the SCOFF questionnaire in a Mexican young adult sample / Evaluación del desempeño psicométrico del cuestionario SCOFF en una muestra de adultos jóvenes mexicanos

OBJECTIVE: To examine the psychometric performance of the SCOFF, a brief screening instrument for eating disorders (ED). MATERIALS AND METHODS: Mexican university applicants (n= 3594, 55.7% female, M age= 18.1 years) completed self-report measures and a health screen. RESULTS: Confirmatory factor analyses revealed one factor for females. However a bifactor model fits better for males and females. Reliability was lower for females (KR20 = .49) than males (KR20 = .59). More females (24.2%) presented risk for ED (SCOFF > 2) than males (11.2%). Nomological validity indicated that risk for ED in young women was associated with demographic (e.g., parental education), psychological (e.g., depression, weight management efficacy), physical (e.g., BMI), and social (e.g., family conflict) indicators in conceptually coherent ways. Fewer variables were significant for males. CONCLUSION: Although the SCOFF may be a useful ED screen in Mexico, further research must examine its criterion validity, sensitivity, and specificity.

OBJETIVO: Examinar el desempeño psicométrico del SCOFF, un instrumento de tamizaje para trastornos de conducta alimentaria (TCA). MATERIAL Y MÉTODOS: Aspirantes mexicanos a una universidad (n = 3594, 55.7% mujeres, edad M = 18.1 años) completaron cuestionarios y una revisión médica. RESULTADOS: Análisis factoriales confirmatorios revelaron un factor para mujeres, aunque un modelo bifactorial funcionó mejor para hombres y mujeres. La fiabilidad fue menor en mujeres (KR20= .49) que en hombres (KR20= .59). Las mujeres (24.2%) presentaron mayor riesgo de TCA (SCOFF > 2) que hombres (11.2%). Validez nomológica indicó que el riesgo de TCA en mujeres jóvenes estuvo asociado con indicadores demográficos (e.g., educación paterna), psicológicos (e.g., depresión, control eficaz de peso), físicos (e.g., IMC), y sociales (e.g., conflicto familiar) de forma conceptualmente coherente. Un subconjunto de estas variables fueron significativas para los hombres. CONCLUSIÓN: El SCOFF podría ser un tamizaje de TCA útil en México. Sin embargo, se requiere más investigación sobre su validez de criterio, sensibilidad y especificidad.

Is there a difference between center and home care providers' training, perceptions, and practices related to obesity prevention?

To compare the obesity related training, practices, and perceptions of home child care providers and center care providers. A self-administered survey was collected from child care providers who attended local child care training workshops in east central Illinois from March 2009 to August 2010. Study results were based on responses from 88 home care providers and 94 center providers. The survey questions addressed child care providers' training in the prior year, their obesity prevention practices including written policies, their perceptions of influences on children's health, and factors determining food menu selection. Paired t tests and Chi-square tests were used to compare the difference by child care type. 81.9% of home care providers and 58.6% of center care providers received nutrition training, while 66.7 and 43.0% of these providers received physical activity training, respectively. Nutrition content, guidelines or state regulations, and food availability were the most important factors that influenced both types of care providers' food service menus. Both care provider types perceived they have less influence on children's food preferences, eating habits, and weight status compared to the home environment. However, home care providers perceived a smaller discrepancy between the influences of child care and home environments compared to center care providers. Compared to center providers, home care providers were more likely to have had training, be involved with health promotion activities, and rate their influence higher on children's health behaviors. Findings underscore the need for obesity prevention efforts in both types of child care settings.

Family and individual predictors of physical activity for older Mexican adolescents.

PURPOSE: Low levels of physical activity (PA) are associated with persistent obesity. Adolescent obesity is linked to adult morbidity and premature mortality. This study examined a model of perceived parental influence in Mexican older adolescents to uncover contemporaneous family and personal predictors of Mexican older adolescents' PA. METHOD: Participants 16- to 25-years-old (n = 3,908), Mexican college applicants, underwent a health screen and filled out questionnaires which included information on PA and potential correlates. A logistic regression model was used to ascertain family factors (socioeconomic status, conflict about PA, and perceived parental PA) and individual factors (age, sex, body mass index, depressive symptoms, enjoyment of PA, and sedentary behaviors) associated with adolescents' PA. RESULTS: Most participants reported being physically active (61.5%); less than half reported physically active parents (40.0%). Perceived parental PA (odds ratio [OR] = 8.67, p ≤ .0001), enjoyment of PA (OR = 2.11, p ≤ .0001), and conflicts about PA (OR = 1.16, p ≤ .0001) were important positive predictors of adolescents' PA. CONCLUSION: PA among Mexican older adolescents is influenced by parental PA. The role of conflicts about PA is likely to be influenced by culture and may indicate that older adolescents' PA is not completely accepted by parents.
