Trying to figure if I am doing this write. The basics is does knowledge about prevention on obesity truly have effect on someone being obese?
1.The dependent variable for this evaluation is Obesity
2.The dependent variable can be though of as a continuous variable by saying, “Obesity can be measured by being overweight by at least 40 pounds.
3.The dependent variable can be thought of as a categorical variable saying, “Whether or not the person is obese.”
4.The most important independent variable for my evaluation is knowledge about prevention of obesity.
5.The independent variable can be thought of a categorical variable by saying, “Whether or not a person taken 4 or more seminars about prevention of obesity.
6.The other independent control variables are age (adults 18+) and geographic location (Tennessee).
7.When controlling for age and geographic location, what effect does the knowledge about prevention of obesity have on he/she being obese?
here are two hypothesis: 8.When controlling for age and geographic location, people who has taken at 4 or more seminars on prevention obesity are more likely to be obese than a person who has taken less than 4 seminars on prevention of obesity.
9.When controlling for age and geographic location, when a person who goes to 4 or more seminars on obesity prevention has a lower BMI than a person who goes to less than 4 seminars on obesity prevention.
does it look right though what i got?

When controlling for age and geographic location, people who has taken at 4 or more seminars on prevention obesity are more likely to be obese than a person who has taken less than 4 seminars on prevention of obesity.

1. What is the effect size that I will use for my sample?
2. What else do I need consider when computing the sample size from statistical point of view?

I understand that some women cannot breastfeed.

It is obvious to me the reasons a woman would choose to breastfeed:
Breastfeeding is the optimal method of feeding all infants, sick as well as healthy, preterm as well as full term. In addition to the myriad health benefits provided to mother and infant, breastfeeding provides significant economic and environmental benefits for families, employers, and society by reducing health care expenses, eliminating the need to purchase expensive formula, and reducing absenteeism from work to care for sick infants. Excess health care costs totaling more than billion must be paid by the U.S. health care system each year to treat otitis media, gastroenteritis, and necrotizing enterocolitis–childhood diseases and conditions preventable or reduced by breastfeeding. When prevention of obesity, diabetes, and other chronic conditions is factored in, the potential economic benefits of breastfeeding are significantly greater.

It is not so obvious the reason a woman would choose to formula feed her child. Could someone give me a good reason?
It is known that these working mothers who can’t take the time to pump are going to miss time from work to care for a sick infant.

Everyone says it is a "personal choice"
What if I don’t want to? What if I would rather not deal with sore nipples? What if I would like my breasts to go back to normal as soon as possible?
Is that what the "personal choice" is about, my self?

Why is this such a personal choice while excess health care costs totaling more than billion must be paid by the U.S. health care system each year to treat otitis media, gastroenteritis, and necrotizing enterocolitis–childhood diseases and conditions preventable or reduced by breastfeeding. When prevention of obesity, diabetes, and other chronic conditions is factored in, the potential economic benefits of breastfeeding are significantly greater.

Do significant disparities in breastfeeding exist, with non-Hispanic black and socioeconomically disadvantaged groups experiencing lower breastfeeding rates, because it is a personal choice?

Maybe more needs to be done to ensure the achievement of our national breastfeeding goals and to create an environment where women and their families can be successful in achieving their personal breastfeeding goals.

I don’t agree with the way women can just choose not to breastfeed.
Do you think making formula only available by prescription would help with this critical public health issue?

Perhaps formula should only be made available to those few mothers who cannot physically breastfeed?
