Question 10

Children in the _____ percentile for body mass index are considered obese.

Accepted Answer

Children in the 95th percentile for body mass index are considered obese, as they have a BMI higher than 95% of children of the same age and sex. This is based on the CDC growth charts, which provide a standard for measuring children's growth and development. Children in the 85th to 94th percentile are considered overweight, while those in the 5th to 84th percentile are considered normal weight.

Question 11

Dr.Annapurna is studying the normal physical growth patterns of children.Every year,she measures the heights and weights of the same 100 children.She will follow their development from birth to age 18.Dr.Annapurna is using a _____ research design.

Accepted Answer

Dr.Annapurna is collecting data from the same group of individuals over an extended period. This denotes a longitudinal study design.

Question 12

Hideo is 4 years old.He's currently 1 meter tall and weighs 16 kg.His body mass index is about

Accepted Answer

To calculate the BMI of Hideo, we need to divide his weight in kilograms by the square of his height in meters. 
BMI = (weight in kg) / (height in meters)^2
BMI = 16 / (1)^2
BMI = 16
Thus, Hideo's BMI is 16 which falls under the healthy weight category for his age and height.

Question 13

Accepted Answer

According to the Center for Disease Control and Prevention (CDC), children with a BMI between the 85th and 94th percentiles are considered overweight, and those with a BMI at or above the 95th percentile for their age and gender are considered obese. Therefore, children in the 90th percentile or higher would be considered overweight.

Accepted Answer

The term "canalized" refers to the idea that development tends to follow a predetermined path despite variations in the environment or experiences. The fact that children's growth patterns are the same worldwide when they receive proper nutrition and care suggests that growth is highly canalized, or predetermined by biology and genetics. This finding also suggests that growth is not highly individualized or variable, meaning that factors such as culture, language, or parenting style have less influence on growth patterns than does biological predisposition.

Question 18

Accepted Answer

Pressuring or bribing a picky eater can create a negative association with the food and make them less likely to try it. Continuously presenting the food without pressure allows the picky eater to become familiar with it and eventually feel comfortable enough to try it on their own.
