- Influence of parental perceived environment on physical activity, TV viewing, active play and body mass Index among portuguese children: a mediation analysisPublication . Carmo, Ariene S.; Rodrigues, Daniela; Nogueira, Helena; Mendes, Larissa L.; Santos, Luana C.; Gama, Augusta; Machado‐Rodrigues, Aristides M.; Silva, Maria Raquel; Rosado‐Marques, Vítor; Padez, CristinaObjectives: The environment is believed to be key in obesity prevention, yet it is unclear how factors in the neighborhood influence weight-related behaviors. The present study aimed to investigate the influence of parental perceived environment on physical activity (PA), television (TV) time, active play and Body Mass Index (BMI) z score, and the mediating role of these weight-related behaviors on the relationship between neighborhood characteristics and children's BMI. Methods: Data of 8472 Portuguese preschool (aged 3-6, n = 3819) and schoolaged children (aged 7-11 years, n = 4653) were collected during 2016/2017. Structural equation modeling was used to estimate the associations between parents perceived neighborhood characteristics (latent variables: unsafety and built/physical environment) and child's BMI z score, PA and TV time. Results: Among preschoolers, the latent variables of the perceived environment were not associated with the BMI, TV time, extracurricular PA, and active play. Among schoolchildren, the unsafety environment was positively associated with both the BMI (SC = 0.050, P = .008) and the time spent watching TV (SC = 0.052, P = .031) and negatively associated with extracurricular PA (SC = −0.125, P < .001). The latent variable Favorable Built Environment for PA (ie, environmental facilitating elements) was positively associated with active play (SC = 0.041, P = .031). Moreover, the TV time was a marginally significant mediator of the relationship between the perceived unsafe environment and the BMI of school-aged children (B = 0.002, P = .096). Conclusions: In conclusion, changes in the environment to targeting parental perception of neighborhood safety could have positive effects on the promotion of healthy weight and the adoption of a healthy lifestyle in school-aged children.
- The environment contribution to gender differences in childhood obesity and organized sports engagementPublication . Nogueira, Helena; Costeira e Pereira, Margarida M.; Costa, Diogo; Gama, Augusta; Machado‐Rodrigues, Aristides; Silva, Maria Raquel; Marques, Vítor R.; Padez, Cristina M.Objective: This study aims to analyze gender-specific associations between sports activity outside of school and obesity, observing to what extent the local built environment contributes to the patterns found. Methods: A total of 2253 children aged 6.0-11.0 years were assessed: 49.3% girls and 50.7% boys. Children's weight and height were measured, age and sex-specific BMI cut-off points were used to define normal vs overweight/obesity. Children's organized sports (OS) activity was assessed by questionnaire, and local facilities for children's engagement in OS were analyzed. Logistic regression models were computed, adjusted for confounding variables. Results: Results showed greater overweight and obesity (25.1% vs 20.1%) and lower OS engagement (66.5% vs 73.8%) in girls as well as greater impact of OS engagement on weight status in girls (OR for having a normal weight = 1.434 in girls vs 1.043 in boys). Additionally, opportunities to engage in OS were scarce for girls. Conclusions: The gender gap in children's weight status and OS engagement might be enhanced by an environmental mismatch that undermines girls' opportunities to play sports. There should be more opportunities for girls to engage in their favorite sports as a means to tackle the obesity epidemic and to promote gender equality.
