Adherence to 24-hour movement guidelines among rural Brazalian preschool children: associations with parenting practices.

Background: Young children residing in rural areas of low-and-middle income countries (LMICs) such as Brazil are at greater risk of obesity and related chronic health conditions. Yet, the extent to which rural preschool children from Brazil aged 3- to 6-years meet the World Health Organisation (WHO) 24-hour movement guidelines is unknown. Parents play a central role in the development of children's movement behaviors with logistic support, co-participation, modelling, and setting rules and limits recognized as influential parenting practices.

Parental Influences on Physical Activity and Screen Time among Preschool Children from Low-Income Families in Brazil.

Children from low-middle income countries (LMIC) are disproportionately affected by obesity, and low physical activity (PA) and high screen time (ST) are major contributors. Parents are key influencers on children's PA and ST, yet, no study has investigated relationships between parenting practices and children's PA and ST in LMIC families. This study examined parental influences on PA and ST among preschool-aged children from low-income families in Brazil.

Dependent variables were characteristics of the children (weight/age, height/age, BMI/age, hemoglobin, and retinol serum levels).

[Evaluation of the incompleteness in the filling out of death certificates of children under one year of age in the State of Pernambuco, Brazil, 1999-2011].

In order to assess the incompleteness in filling out death certificates (DC) in the regional health offices of the State of Pernambuco a descriptive study was conducted on data for infant mortality information on deaths of children under one year of age in the municipalities of Pernambuco in the 1999-2001 and 2009-2011 threeyear periods. The percentage of incompleteness was based on the blank/unknown responses in the DCs per regional health office and the proportional variation rate of incompleteness between the two periods. It was observed that the filling out of information did not show a well-defined pattern per office, with a reduction in incompleteness occurring for most variables, though the sex, age and place of occurrence of death variables alone revealed ≤ 5% incompleteness in the second term of study, which was considered excellent in terms of the Romero and Cunha scores.
