The Spanish version of the Home Environment Survey (HES) among families of children with overweight/obesity: a validation study

PURPOSE

The aim of this article was to validate the Spanish version of the Home Environment Survey (HES-S) and was divided in two studies: (1) to assess the reliability, convergent validity of HES-S in a survey of 145 parents of children with overweight/obesity; (2) to study the magnitude of the association between children's BMI status with the latent scores theoretically defined by the HES model.

METHODS

To test the scale and the model, a confirmatory factor analysis (CFA) and a path analysis were carried out among a sample of 156 parents of preadolescents (106 overweight/obesity and 50 normal-weight children). No CFA or EFA were carried out in the validation of the original instrument.

RESULTS

Study 1, both the Physical Activity and the Eating Habits components of the scale showed adequate levels of internal consistency for the majority of the scales, except for two. One of them, Healthy Eating Parental Policies (HEP) subscale was reduced after excluded two items, although it did not improve substantially. This model indicated that there was a significant association between the two Eating Habits scales and the child's weight status, but child's weight was not associated with the Physical Activity components. Convergent validity was confirmed by correlations with related variables: family eating habits (F-EAT), parent's physical activity (IPAQ), and children's physical activity (assessed via accelerometers during one week). Study 2, our results replicated the original four factor structure proposed for physical activity (CFI = 0.99; RMSEA = 0.03), but the original factor structure of the eating habits component was not supported. In addition, the relationship of the child's weight status, the Physical Activity components, and the two scales of Eating Habits (Parental Modeling and Policies) was explored with a path analysis showing good fit indices (CFI = 0.95; RMSEA = 0.06). Child's BMI was negatively associated with Healthy Eating Parental Role Modeling (r =  - 0.21) and with Healthy Eating Parental Policies (r =  - 0.19), but not with the factors of Child's Physical Activity model.

CONCLUSION

To our knowledge, this is the first instrument to assess obesogenic family environment in Spanish speaking countries, which is a relevant dimension within a health perspective so as to implement new policies and strategies in obesity tertiary prevention. Overall, the confirmatory factor analysis of the HES-S has only provided additional support for one part related to Physical Activity. In addition, Child's BMI was correlated with scales of Eating Habits but not with Child's Physical Activity factor. These results clearly suggest that further research is warranted.

Feasibility, acceptability, and effectiveness of a multidisciplinary intervention in childhood obesity from primary care: Nutrition, physical activity, emotional regulation, and family

Childhood obesity is a growing problem with a complex aetiology, for which multidisciplinary interventions are required. Our programme describes a novel structured psychosocial family-based intervention targeting the emotional regulation in childhood obesity, using a train trip metaphor aimed at improving healthy lifestyles for the family. The aims were (a) to describe the feasibility and acceptability of this psychosocial family-based intervention among children with overweight or obesity in primary care and (b) to examine the effectiveness of the "ENTREN-F" programme (with family intervention) compared with the "ENTREN" programme (without family intervention) among Spanish children regarding anthropometric variables, physical activity, emotional well-being, and family functioning. Children were randomly allocated to either ENTREN-F programme (n = 30) or psychological intervention for children (ENTREN, n = 40), and assessments were carried out over time (T₀ baseline vs. T₁ post/6-month vs. T₂ 6-month follow-up). Both parent groups expressed high levels of satisfaction with the interventions. ENTREN-F resulted in higher adherence to treatment and was more effective in improving z-body mass index, reducing children's anxiety, and increasing family adaptability than the ENTREN programme. There were no significant changes in parents' emotional well-being and expressed emotion. Both groups improved in the children's emotional well-being and light physical activity. In summary, this multidisciplinary psychosocial family-based intervention was succesful.

Interplay between weight loss and gut microbiota composition in overweight adolescents

The aim of this study was to determine the influence of an obesity treatment program on the gut microbiota and body weight of overweight adolescents. Thirty-six adolescents (13-15 years), classified as overweight according to the International Obesity Task Force BMI criteria, were submitted to a calorie-restricted diet (10-40%) and increased physical activity (15-23 kcal/kg body weight/week) program over 10 weeks. Gut bacterial groups were analyzed by quantitative real-time PCR before and after the intervention. A group of subjects (n=23) experienced >4.0 kg weight loss and showed significant BMI (P=0.030) and BMI z-score (P=0.035) reductions after the intervention, while the other group (n=13) showed <2.0 kg weight loss. No significant differences in dietary intake were found between both groups. In the whole adolescent population, the intervention led to increased Bacteroides fragilis group (P=0.001) and Lactobacillus group (P=0.030) counts, and to decreased Clostridium coccoides group (P=0.028), Bifidobacterium longum (P=0.031), and Bifidobacterium adolescentis (P=0.044) counts. In the high weight-loss group, B. fragilis group and Lactobacillus group counts also increased (P=0.001 and P=0.007, respectively), whereas C. coccoides group and B. longum counts decreased (P=0.001 and P=0.044, respectively) after the intervention. Total bacteria, B. fragilis group and Clostridium leptum group, and Bifidobacterium catenulatum group counts were significantly higher (P<0.001-0.036) while levels of C. coccoides group, Lactobacillus group, Bifidobacterium, Bifidobacterium breve, and Bifidobacterium bifidum were significantly lower (P<0.001-0.008) in the high weight-loss group than in the low weight-loss group before and after the intervention. These findings indicate that calorie restriction and physical activity have an impact on gut microbiota composition related to body weight loss, which also seem to be influenced by the individual's microbiota.
