may vary because of different data collection mechanisms (body weight taken in person, age reported via online survey).
dFor questions with yes/no answers, the percentage that reported “yes” is shown; the value column displays the value of the chi-squared statistics for a two-tailed test.
eWhen the expected cell count is less than 5, the chi-squared statistics cannot be calculated.
