Relationship between Parents' Physical Activity Level and the Motor Development Level and BMI of Their Children.

All the variables that arise in family dynamics can have significant effects on the lives of children concerning their nutritional status and motor development. The objective of this study was to relate the PAL of parents to the level of motor development and the BMI of their children. A total of 198 subjects participated, with the age of the students ranging between 8 and 10 years. To measure the BMI, the norms for the nutritional evaluation of children and teenagers from 5 to 19 years were used; to identify the motor behaviors, the TGMD-2 Test was used; and to identify the level of physical activity of parents, the International Physical Activity Questionnaire (IPAQ) was used. For the analysis, the independent samples t-test and the non-parametric Mann-Whitney U test (Wilcoxon) were used, and for the correlational analysis, Spearman's rho test was applied. This study found no significant correlation between the activity level of parents and nutritional status variables (p = 0.162), or between the PAL variables of parents and the motor development of their children (p = 0.738). A parent's level of physical activity does not have a direct relationship with the nutritional status or the motor development of their children.

Sylvatic foci of the Chagas disease vector Triatoma infestans in Chile: description of a new focus and challenges for control programs.

Triatoma infestans is one of the main domestic vectors of Chagas disease. Reports of wild habitat occurrences have recently increased. In Chile, after a successful elimination campaign of T. infestans domestic infestation, a sylvatic focus was reported in bromeliads in the metropolitan region. Here, we report a new focus of sylvatic T. infestans inhabiting rock piles in the Valparaíso region in central Chile. All T. infestans captured were nymphal instars living among the stones, which were inhabited by several mammal species, along with the sylvatic triatomine vector Mepraia spinolai. We found a prevalence of infection with Trypanosoma cruzi of 36.54% in T. infestans, similar to the previous report for sylvatic specimens from bromeliads. Sylvatic populations of T. infestans should be studied at different geographic scales to elucidate their role in the maintenance of the sylvatic transmission cycle of T. cruzi and their possible role in threatening the domestic elimination of this vector. This information should be used to re-design the control programs in Chile to avoid the re-establishment of the domestic cycle.
